Hey guys,
So after many months with the XT720 and alot of flashing and trying to get the most out of my battery, i've come up with a few conclusions about battery life in general and how to extend it. I thought I'd share here. This is mostly aimed at people who are new to android and have not experimented like some of the more advanced users we have on this forum. Hope you find this helpful and please feel free to make additions.
General Battery Info
The XT720 was my first android phone, and I came from a long line of typical nokia phones whose batteries would last for ages. I had no idea the kind of power an android device would use. When I started out using it, i was surprised at how quickly the battery would die. You'd think with advancing software we'd have better batteries but sadly batteries are lagging behind in technology. Generally speaking you can expect the following battery life from your XT720.
Heavy use: 10-14 hours
Moderate use: 16-20 hours
Light use: 1 day - 1 day 12 hrs.
Note: New batteries improve with each charge cycle. It is recommended to go through a few complete charge cycles when you buy a new phone. After that, complete discharges are not recommended and its smart to start charging your phone when it hits the 20-25% mark.
How to improve battery life
1: Battery Calibration
If you've ever flashed a new ROM, you must have noticed a sharp decline in battery performance. This is partly due to old battery statistics left behind from your old ROM. Android is a smart OS and collects information over time. The more you use it, the more accurate it gets. In the same way it collects information from your battery usage and reports your battery percentages according to that. When you flash a new ROM, sometimes android thinks that your battery is 100% when its really lower than that and that causes relative reduced battery performance. To deal with that it is recommended that you use a nifty free app called Battery Calibration from the android market. What this does it removes the old battery stats and allows your new ROM to create its own battery stats. Charge your battery to full, use the battery calibration. Drain once till phone turns off by itself and charge to full again. You will notice a sharp increase in battery life.
2. Battery Managment
We all know that android has its own battery management built in but it usually doesnt give complete information about the phone. For that you need to dive deeper into the settings. Usually if you experience battery drain its because of a rogue app and believe it or not some common apps you wont think off drain unnecessary battery. To see your complete Battery Stats input this code into the dialer.
Code:
*#*#4636#*#*
This will take you to a bunch of options. What you're interested in is Battery History. When you tap that it will show you two drop down menu's.
1) Other Usage
2) Since last unplugged
Other usage shows you how long your phone has been running and how long it has been asleep. Also shows you how long your wifi has been on and running and how long your screen has been on. It is important to see how long your phone has been running. For example if your phone has an uptime of 20 hours and its been running 5 hours out of that. Your run time is 25%. Which is very good. Sometimes an app can run even when your phone screen is off. This will represent a longer run time even when you have your phone lying on a desk or something. See this setting and correlate with the amount you have used your phone. Does it seem normal? If no then use the first drop down menu and select
Partial Wake:
Partial wake is basically, any app which takes your phone out of sleep mode to use the CPU even when youre screen is off. These are apps which need to sync or use the phone resources. In this you will see a list of apps and how much they have caused a partial wake lock. See anything unsual? For me one app that caused unsual drainage was latitute. Yes, i had simply signed into it and i didnt know it was updating my location every 5 minutes. Extreme battery drain for me even when my phone was idle. See which app was draining your battery and either tweak the settings or remove altogether.
GPS, Sensors, CPU:
You can also see these in the first drop down menu. Certain apps like screeble use the sensors alot, and hence cause drain. Obviously games, camera, will stress the CPU. See if anything is causing drain in that and adjust accordingly.
Miscellaneous Information
After you have dealt with rogue apps that you don't use that drain youre battery your battery life will depend on how you use your phone. But hopefull these tips will help you with increasing your battery life. I do have some more information on different settings and supposed battery saving applications.
Autosync: When you enable auto sync, you allow google and other accounts to sync on a regular basis. This is important for people who need to use push email etc. It does not drain battery IF you tweak what you need synced. In google for example you can have your contacts, calendar, google+, google reader, gmail all to sync by default. If you just need email, please untick the rest. This will help you save battery life. Increase your update times for facebook and google+ if you dont recieve many updates all the time or turn them off altogether. If you have many services syncing at the same time you will get battery drain.
Wifi Sleep Policy: This is sort of a hidden menu. If you go into wireless & networks >> Wifi settings >> settings key >> advanced >> wifi sleep policy. This has three settings. Never close down wifi, never close when charging, or close with screen off. If you choose never your wifi will always be on, which will in turn crunch the **** out of your battery. If you use it off with screen off, remember it takes about 5 minutes to turn the wifi off. I personally use the never with plugged in. Its an intermediate. So when im plugged in wifi always stays on and when im not it follows the screen off protocol.
Wifi Vs Mobile Data: Having mobile data on all the time, does not drain battery. The only time the battery gets drained is when the data connection is active i.e you have many apps on autosync youll see your battery going down. If you arent doing anything and your phone is connected to Edge or 3G your battery will drain regularly. 2G networks drain less than 3G keep that in mind. If you are actively using your connection, wifi will take less battery because speeds are faster and you will be using it for a little time. Also your signal strength has alot of effect on battery. If you have crappy 3G signals your radio will actively be searching for a connection the same goes for wifi. That is important to keep in mind.
Control Background data: By selecting this option you can allow or disallow apps to connect to data without any permission. Some apps require this like the android market. If you uncheck this apps wont be able to sync automatically in the background.
Milestone Overclocking: This is fairly obvious. The higher you overclock with higher vsel the more battery drain you will have. Some use set cpu with profiles but I found that if i set the setcpu too low while idle It takes time for the cpu to charge up when i recieve a call or turn the screen on. Ringtones lag etc etc. I let android do my CPU management and its fine. and comfortable setting would be 850 MHZ, 56 vsel but you can change according to your phone usage.
Juice Defender/ Screebl / Task killers:
In my personal experience with juice defender ultimate I found that with the above precautions juice defender didnt make much of a difference and actually used more battery. First off theres an extra process going on in the back. Second activating and deactivating the connection everytime the screen goes off uses more juice because your radio has to search for the signal hundreds of times as compared to not having it in the first place. Screebl is good if you dont want your screen to annoyingly turn off while youre doing something but it surely doesnt save battery life. Task killers are a no no for android. They kill tasks which start up anyways, its better to use autokiller memory optimizer which tweaks androids internal memory settings and allows for more free ram without killing processes without reason.
System Apps:
Some system apps run uselessly in the background specially with stock ROM's this is called bloatware. Remove all unused system apps with titanium backup to stop them from running in the background for no reason at all.
A final word
Finally after all this tweaking, just use your phone as normal. Dont worry about the battery all the time checking how much its drained, itll mess your head up and make you enjoy your phone less. Battery temperature also changes battery life. Keep your phone out of the sun or in hot places.
Thanks, good article.
Very detailed and useful

Thanks for this interessting article!
Could you make a list of the bloatware that can be safely removed?
I figured this would just list all the usual stuff I've heard. I'm glad to say I was wrong! A bunch of useful info here I now plan to put to use. Many thanks
Might want to mention the display being the biggest drain of battery on this phone. Setting it to automatic brightness or lower will increase battery life. I love the screen at full brightness so I don't really follow that, but for those looking to squeeze some extra time and don't mind less brightness...
Thanks guys, glad you people found it useful.

Yes! Can't believe I missed that one out. In the start id use the lowest brightness setting, which would be fine indoors. But outside it was impossible to see the phone because of its insanely reflective glass. Since we have an ambient light sensor I use it on automatic and it does a good job. Full bright strains my eyes abit thats why I dont keep it on full bright So for people really wanting to save the juice you can keep your brightness on the lowest level. Also when you take the phone out of your pocket and use it, its better to put the phone to sleep with the power button than let it timeout by itself. Those 10-15 seconds for each time you use phone count towards many minutes of unused display time in the end and does make a difference.
This is a very gd post with lots o useful info!! ok i have a qn, is using the phone a lot while the charging good for the battery? And if u let the battery charge even though its already 100 percent for an hour good? srry if it is noob qn...

1. Using your phone while charging does not affect your battery life, and is neither good nor bad. It is perfectly normal to use your phone while charging and is sometimes recommended while doing battery intensive tasks for example navigating while driving, wifi tethering, playing memory intensive games and finally outputing video through HDMI.
2. Overcharging was a phenomenom is older lithium ion battery. New batteries have bypass circuits. So when your phone reaches complete charge, it does not charge any further. So you should not be worried about overcharging your XT720.
Hope this helps.
Excelent article and good quality info. Thanks and best regards!
awesome article! Great information. Thanks a lot for putting that together. I have already started using a few of the tips mentioned.
u da maaan dude, thanks for a very detailed and informative article

I had seen one too many posts about people asking and complaining about battery drain issues on their G1 phones and it gets tiring to read it every 5-10 posts. So I decided to create this thinktank to pool in ideas from the community and create a set of best practices to maximize mileage of our phones. I'm currently using a HTC Dream with stock battery and my battery life is pretty good with light to medium usage. I would like to contribute to the community by creating this thinktank thread. I hope this can help as a guide for myself and for people who have been having numerous battery drain issues on 5.0.7-DS and variants of this distribution.
This is NOT the ultimate end-all solution for your battery problems. These are just steps to tackle the problem. If you want minimum to no battery drain keep it plugged to socket or plug it in a car battery.
If you would like to contribute your experience, or make any corrections please do not hesitate to post and I'll include them if they seem fit and attach your name as reference. I'll also do my best to give credit where credit is due. Please see the references at the bottom part of the post. Please do not clutter this thread by doing "I'll try this" or "It doesnt work" post. Its more important for all of us to know WHY it work/didnt work. Stick to topic, and be constructive. Be intelligent. Think first.
0. Update your Radio
Updating your G1's radio to the currently-latest version (2.22.23.02) should give you better battery life as well as signal reception (you can always switch back to 2.22.19.26I if it doesn't work out for you)
1. Recalibrate
Take note that BATTERY STATS ARE WIPED whenever you flash a new rom. (since full wipes are required whenever changing ROMS, and /data is where the battery info is.) This usually leads to inaccurate battery readings.
Here's how you recalibrate properly:
- Charge your phone till the GREEN LED shows up. Leave it for another hour.
- While plugged, go to recovery and wipe your battery stats.
- Right after the phone is booted up and settled, unplug and use as per normal till it shuts off. Then charge as per normal.
2. Disabling some basic phone hardware functionality
Turn off GPS, WIFI when not in use. And brightness set to manageable levels. Even loudspeaker. This is self-explanatory. Automation software like LOCALE can be useful, but usually all it takes for you to turn off your ringer, or turn on wifi when you're at a specific area is just a press on the Power control widget.
3. Overclocked kernels
Running on full overclock speed (by default is 528mhz or even higher on some kernels) will drain your battery faster and you'll notice significant heat increase when you're using your phone along with 3G.
Although im using pershoots 576mhz overclock kernel, I do not max it to 576 unless needed. The reason why I use his kernel is due to its UNDERVOLT capability. I have set up my phone using SetCPU
MAXFREQ: 480,
MINFREQ: 176
CPU Governor : ONDEMAND.

Usually I would set my phone to 384mhz if im going to stay on it longer (texting/long browsing etc). On the sleep mode I set it to 122mhz to 384mhz.
4. Tame your widgets, minimize using them.
Widgets that constantly connect to the internet, or constantly refreshing on the screen to update data being shown on the screen at extremely small intervals would also give you battery drain. Minimizing widgets can help minimize applications running in the background (free up memory) and avoiding your phone going on "partial sleep". Also tweak your widgets to update as less as manageably possible. If for some reason you can't see the next suggestion.
Aside from that you might want to disable Background syncing and do manual syncing. Aside from saving your data plan, it also saves battery life. You can disable it by doing the following:
Menu > Settings > Accounts & Sync > Background Data - OFF
Click to expand...
Click to collapse
manually update your facebook widget or contacts/gmail by
Menu > Accounts & Sync > Facebook (or GMail) > Sync.
Click to expand...
Click to collapse
5. 3G, 2G, switch off, or automate it.
You'll notice that inside the default settings for mobile networks. Setting to 2G will "save battery" which is actually true. The connection will definitely be slower, but if you like your phone to last longer throughout the day, either switch to 2G or turn it off altogether.
Also, similar to juice defender, I use 2g/3g toggle and toggle data as and when needed.
Another suggestion that I just found out recently is the use of Juice Defender app [d]. It automatically turns on or off your APN settings at intervals. You might want to try to look at that app if you cannot do #4
6. Disable live wallpapers. Auto Updating Sense
Remember that 2.1 isnt actually built for our old phones. and livewallpapers do require cpu/gpu processes. These are also running in the background and may run while your phone is asleep. So turning them off will benefit you.
7. Refrain from using Automated task killers and choose what you kill.
If you see that the app you had been trying to kill a few times keeps coming back. Stop killing it. Everytime you do, and whenever it respawns, CPU flies to 100%. Go back to #4.
8. Disable Market notifications.
- Open the Market application.
- Select the Menu key.
- Select Downloads.
- Select the Menu key again.
- Select Notifications.
- Select the Do not notify me radio button. press [Ok]
Click to expand...
Click to collapse
9. Make your phone sleep.
Open your spareparts application, Go to End button behavior. Select "Go to sleep"
10. Under the hood tweaks
10.1 Extending Wifi scan intervals
Edit the wifi scan interval in /system/build.sapphire.prop (or build.trout.prop if you have a G1)
# Time between scans in seconds. Keep it high to minimize battery drain.
# This only affects the case in which there are remembered access points,
# but none are in range.
wifi.supplicant_scan_interval = 45
Click to expand...
Click to collapse
Changing this number to just 90 second will half your wifi scans. Obviously larger numbers can mean less wifi scans which means more battery life, though it may take a little longer for your phone to pick up a remembered access point when in range. This is not just a CM/Eclair thing, it can also work for Donut phones.
This setting needs a reboot after editing the file. Edit it with Root Explorer, or nano as root if you have CM5, or pull the file with adb then edit it then push it back.
11. Remove your phone from your pocket whenever you can.
Body heat deteriorates battery life no kidding! there had been already studies to back it. I keep my phone either on my hand or outside of my pocket to keep it cool. Do whatever is manageable in your environment. If you're using your phone as a music player streaming using streamfurious and stuff. dont let your body heat add to the heat already been generated by your phone itself.

really? isnt warmth charging batterys? in my old gameboy years i always put my batteries on the heater when the drained completely and after an hour i could play again with the old batteries.
1. Recalibrate [a]
Take note NOT TO WIPE BATTERY STATS whenever you flash a new rom and your battery is less than 90%. This usually leads to inaccurate battery readings. If you already wiped your battery during one of your flashes, here's how you recalibrate properly:
- Charge your phone till the GREEN LED shows up. Leave it for another hour.
- While plugged, go to recovery and wipe your battery stats.
- Right after the phone is booted up and settled, unplug and use as per normal till it shuts off. Then charge as per normal.

This is true, but since battery stats are stored on the data partition, a data wipe also deletes the battery stats. A lot of rom's require a full wipe, meaning data and dalvik, so battery stats are deleted whether you select the option or not.

Hi!
Yes Im very familiar with that practice because i do that too. The reason might be because of the composition of the battery (alkaline, non alkaline). Usually we put it under the sun so that the heat will help change the composition of the compound inside the battery in order for it to lower down its resistance. Leading to a "charge".
But now we are using Li-Ion batteries, and I do not suggest putting them under the sun because it will deteriorate your battery capacity holding charge and its lifecycle.

how about going to setting - about phone - battery use?
there you can find out exactly whats killing your battery and take appropiate action.
Also, similar to juice defender, I use 2g/3g toggle and toggel data as and when needed. Using these two widgets i have no battery issues.

change preferred network type helped for me increasing battery life
Hello all,
as describe in post
forum.xda-developers.com/showpost.php?p=6432560&postcount=1
changing preferred network type worked for me.
default setting: WCDMA preferred drains my battery in a few hours, crazy
within CM 5.0.7-test7 I was able to change to: GSM/CDMA auto and it worked
But now in the final release 5.0.7-DS I can not select this setting. Perhaps it correlates to the this (PRL) info in brackets.
It seems that no "auto" setting want be working so I am trying WCDMA only right now and will see if I have a network in 2G networks too.
Bye morT
Hhmm let me think…
Running a prrocessor that's massively overclocked with software that was never meant to run on our g1's I have an idea.
****** off back to stock or get over it
I mean seriously people come on, we have set cpu for power profile management, basic battery usage which is dim screen, turn off wifi and 3g when not in use blah blah blah same **** written in every guide about battery life for ANY roms from cupcake to eclair.
As I said, get over it or go back to stock.

im sorry does turning on "display battery status" in spare parts still effect battery life? TIA
Ive noticed that bluetooth is killlllling battery life, but dont know if its normal. I charged to 100% and turned everything on, leaving screen on the whole time and what not.
While I was actively using the net over WiFi, I had nothing using the bluetooth, and both seem to eat up 20%..
This might be normal, might not be, but thought it was odd that it being on, but not in use, ate up just as much as functioning, in use, wifi.
whats funny to me is as soon as my phone dies i plug it up reboot it a few times and my battery is at 70%
.... i think its not reading correctly .. i mean fully charged play talk text browse till it shuts off .. plug it in turn it right back on then reboot ..
and my battery is back at 70% which is weird ... anyone else notice that???
also wifi, gps is on screen brightness is standard !!!
batteries really seem to be the least developed technology in our high tech phones. feels like a sportscar with a one gallon tank...the fun's over quickly...
turned off my 3G and got a lot of additional battery life. with bad 3G reception (like in the place I live in) the phone was sometimes sucked empty in just a few hours, now I get two days.
another thing that really helped me extend my battery life was turning on airplane mode when I went to bed.
how about dont use overclock or any other cpu speed up tool....maybe the speed they are factory set to is there for a reason...Hmmmmmmm

Since I have a background in electrical theory and chemistry, let me end this debate once and for all: heat makes atoms (and therefore molecules) move faster. Lack of heat (cold) makes them move slower. In general, fast-moving atoms in batteries mean MORE power, not less. The reason your car doesn't want to start when temperatures are subzero is that the battery acid (electrolyte) molecules are moving too slowly to oxidize (give off e-, electrons) and turn back into positive ions. The same is true for the ol' Gameboy AAs -- put them on the heater, the dry cell warm up, and more electrons are transferred to the anode by anions, the positive ions (cations) are more able to travel to travel back to the cathode (in the case of dry/wet-cell rechargeable storage batteries). Heat acts as a catalyst to produce electricity. Some of you may have even taken your car battery indoors if the electrolyte froze in the winter. Some of your cars may have battery blankets or even battery heaters if you live really far up north. In addition, the process of charging a Li-Ion, Ni-mH, or even lead acid battery will produce heat, because chemical conversion is bi-directional, but anyway . . . you charge the G1, it gets hot. You use it heavily, it gets hot. You know you're spending electrons somewhere when it gets hot period. Keeping the phone cool will not increase battery life or make it charge fast. What lower battery temperatures will do is lengthen the battery's overall life. What happens if you leave meat out in 100F/30C temperatures? It goes bad quickly. Same principle in Li-ion. The rechargeable battery is ideally an efficient, closed system of ion exchange that should work for many (hundreds) of duty cycles, but eventually heat plays a role in deterioration of the electrolyte and chemical catalysts inside.
So put your extra charged batteries (but you don't want a Li-ion or Ni-mH battery to sit very long in an discharged state, so be careful here) in the refrigerator in an airtight bag (rotating on a daily basis) if you really want them to last a long time, but don't charge them frozen (ka-boom!) and remember cold batteries charge slowly. Car batteries in sub-tropical areas are replaced at a rate of about once every 24 months, but in Sweden? Maybe every five or six years. Cold temperatures slow down chemical deterioration just like cold keeps that steak from becoming maggot food.
Again, a hot G1 may weaken its own internal components and batteries over time, but putting it on ice won't give you an extra 6 hours to oogle Miley Cyrus' vBlog
Hope this helps.
For me, unless I'm expecting a text or a call always have my phone on airplane mode. I turn it off every hour or so to see if I got any unimportant texts, and then turn it back on

I'm a truck driver and I'm a heavy user.
I did too before I made the changes below. These all work with the Stock Rom.
1. Installed No Lock (so that I don't have to swipe the screen to unlock, just push the power button)
2. Set screen to turn off in 30 seconds.
3. Installed Brightness Widget (allows changing the brightness from the home screen
4. Installed Screen Filter (lets me really darken my screen at night.
Try those and see how you do.
5. I then flashed the Infused Rom (I now get up to 10-14 hours)

Custom kernal and rom
Running refused and infusion 1.8 rom and I get 14 hours with heavy data use

Also, Turn off GPS and Wifi when you're not using them.
Battery
After much experimenting and monitoring of battery use I find that the biggest drain is the screen display, so go to settings-->display-->brightness and lower the screen brightness as low as you comfortably can. Also when you you are not using the phone make sure the screen is off, I have trained myself to automatically hit the power button every time I put down the phone. If you listen to music through your phone make sure the settings on your music players allow the phone to play when the screen is off and turn the screen off while it plays.
GPS also drains the battery, so I keep it turned off when I don't use the Nav. When I use the Nav I know the battery will drain at a rapid pace, nothing you can do there, even if I have the phone plugged in to car power while using Nav it still drains the battery! Drains slower than unplugged navigating but still drains.
If your watching videos then your S.O.L. there's really nothing you can do that will increase battery life enough to make a difference during video playback.
I get 10-12 hours with regular use and stock rom. Worst was 8 hours best was 24.
Thanks for all the advice this has really helped my battery

There was a recent post that showed a shortcut for changing the screen brightness from the homescreen without any additional software. First, turn off auto brightness. Second, tap and hold the menu bar at the top. Third, slide left to reduce the screen brightness and right to increase screen brightness.

After much experimenting and monitoring of battery use I find that the biggest drain is the screen display, so go to settings-->display-->brightness and lower the screen brightness as low as you comfortably can. Also when you you are not using the phone make sure the screen is off, I have trained myself to automatically hit the power button every time I put down the phone. If you listen to music through your phone make sure the settings on your music players allow the phone to play when the screen is off and turn the screen off while it plays.
GPS also drains the battery, so I keep it turned off when I don't use the Nav. When I use the Nav I know the battery will drain at a rapid pace, nothing you can do there, even if I have the phone plugged in to car power while using Nav it still drains the battery! Drains slower than unplugged navigating but still drains.
If your watching videos then your S.O.L. there's really nothing you can do that will increase battery life enough to make a difference during video playback.
I get 10-12 hours with regular use and stock rom. Worst was 8 hours best was 24.

How does it drain your battery when its plugged into the car? I have never seen that on any cell phone. That my friend is messed up if true.

It seems that Samsung ****ed up and included phone CPU/screen/etc usage when measuring battery charge current.
This means that the 600 mA stock battery charge current limit isn't just going to the battery, it's split between battery/screen/CPU. If screen/CPU/etc go above 600 mA (Navigation at full brightness seems to be the most common way), battery starts draining.
It also means that unless there's something I'm missing (which I could be since the MAX8998 datasheet is super-ultra-secret), our phone isn't going to be able to do proper charge termination - if the screen is on/CPU is running, it will cause a falsely high battery charge current reading, which will cause charging to fail to terminate.

I found that juice defender helped my battery and i just use the free version it's a great app
I used Iphone 3g 3gs 4. None of them drain battery like this one. First time use Android phone and getting a bit disappointed of this phone. It's draining 2% every 5 mins and im using stock Rom.

Install a ROM. Infused v2 nearly doubled my screen-on battery life and tripled my screen-off battery life.

look in about phone battery use to identify the biggest battery user, it should be the screen. anything else and there is a problem.
the cell standby may go high on froyo rom, turning on flight mode and turning it off will correct that, it's an android bug.
on gingerbread the android os or android system may hog battery occasionally. some think it is the wifi sleep policy but it pops up on me without setting the sleep policy. the fix for that is to pull the battery for a couple minutes and put it back in and restart the phone.
next manage the screen brightness
install a custom rom, there are issues with certain firmware keeping sensors active wen they shouldn't be.
turn off unneeded sync options (i find that auto fetching my email uses a lot especially with my gmail already set to sync),
use wifi when you use the internet if possible, turn it off when out and about.
monitor cpu useage of apps that are cached in the task manager
kill apps that use cpu
if needed turn the max cpu clock down to 800mhz
set "use wireless networks" for location when possible for general location (limited to city level at times)

Actually, high cell standby is OK if the phone is screen-off often.
Cell standby is always my top user - but my phone is sitting on my desk with the screen off frequently, in a location with weak signal. Weak signal makes cell standby usage go WAY up.

Using titanium backup I froze drm content 2.2.1 and this significantly increased my battery life.
Sent from my Infuse. It is what it isn't.
JuiceDefender!!
I agree JuiceDefender works!! I had to charge in the middle of the day. Now with moderate use it will last all day Im on stock Rom.
I easily get 2 days out of my Infuse, no idea how some of you are managing to only get 8 hours. After rooting my phone and freezing the bloat i easily get twice the battery life of my prior iPhone 3GS.
*Disclaimer* This is all from a personal experience and testing/research from a long time android user, what I have discovered over time and has helped me and some friends. This will work whether your rooted OR not. I kept it as basic as I can so everyone can benefit. If you dont like what you read and disagree, or want to add something PM me, Ill change/add and give credit to you. Hopefully, this can grow with the community.
*Rooted Section Will be Added*
*When I charge my battery I usually drain it all the way down or as much as i can (around 20% left) then charge plugged in till green, then power down and charge for another hour or so. Not sure if this matters or not but seems to help me out try it!*
This guide will help you if your rooted or non-rooted, all the apps I talk about I honestly have no ties to the devs. I don't use any SUPER AWESOME AMAZING BATTERY SAVER 5000 apps or anything like that. Those mostly just turn ur radios off and on and kill apps in the background. In my experience a lot of them cause syncing issues with my e-mail and other notifications. I like to receive my information instantly not have an app waiting for me to turn my screen on to check for updates.
About my personal setup: Basically, I want my phone to last me all day but still perform well with a heavy use, WITHOUT needing to constantly change settings to save battery. With what I have here Im able to keep my Sensation running for a full day of moderate-heavy use (7:30am to around 10pm) with its STOCK battery (Did damn well on my Evo 4G too). Days of very minor use Ive gone into the second day with 60% + battery. Yes, I use all my home screens and have a good amount of widgets, I love sense and its widgets. I play games, surf the web, do a lot of texting, listen to a lot of music, decent amount of fbing and email, usually take a few pictures a day. Half my day is wifi/other is mobile data.
Here goes the real basics, mostly common sense here not trying to insult anyone. Feel free to browse thru it quick (green text) if your not totally new to the android scene, whats after it will be a good read for noobs and vets.
*I use the power control widget, make getting to a lot of settings quicker. Why waste battery digging thru menus?*
Basics:
-Screen brightness: (duh ) these pretty screens eat battery brighter=quicker drain naturally and from my experience leaving it on Auto Brightness kills more battery too. Each time your phone pulls information from the sensor to decide on how bright it should adjust itself too.
-GPS: If GPS is on it should not effect battery unless an app is using it and you see the GPS icon on your notification bar. I noticed a very slight increase in mA discharge when i had it enabled, to be safe leave it off if you dont use it extremely frequently.
Location thru mobile networks: Not to hard on battery. I leave mine on it does add drain but it takes away from my weather widgets updating when Im traveling.
-Bluetooth: Moderate battery drain. I honestly don't use it at all myself but if you do try your best to keep it off when not in use.
-Wifi: Android has gotten a lot better at managing wifi over the past few years. It doesn't drain that bad on battery and it shuts off/on periodically on its own when screen is off depending on whats using it.
Google Back-Up: Takes a little juice here and there no biggie. I dont use it just because I like to fresh install my apps when I try a new rom, run into less problems that way.
2G/3G/4G: This varies phone to phone, the slower speed the better battery life. If you know your not going to be using 4G for a while turn it off. I leave mine on 4G or wifi all day with my sensation. When I had Sprint and my Evo I would leave it off most of the time. Depending on your carrier and how their data works this is a big one. T-Mobile seems to handle well, Sprint and Verizon's 4G Ive seen eat an insane amount of battery.
Sync/Background Data: I lumped them together because sync is pretty much reliant on background data. These kill a lot of your battery in general. It syncs your apps (email, facebook, google data, contacts, etc.), the periodic checks your apps do to check for and download new emails and notifications, using background data (data still transmits when screens off). I always leave these on and still manage great battery life, I like things instant if I wanted to wait Id just wait till i got in front of a PC. Sync and Background data are the settings most battery saving apps control because they really can help your battery if you turn it off. You can control what core apps sync in settings>accounts and sync. Or the power widget that 95% of android phones have has it on there. I recommend minimizing the amount of apps you allow background data with, example: WeatherBug first launch it asks if it can automatically update itself in the background for apps were thats not necessary hit no.
Radio/Airplane Mode: Pretty self explanatory, turns off your connection to your wireless provider. No point in ever turning it off in my eyes, your phones no longer a phone.
What has really helped me with my battery life (non-basics):
There is a lot to be said when it comes down to 2.2+ android phones and whether they need a task killer anymore or not. Since Ive had a lot of android phones and a few now that are 2.2+ Ive done a lot of testing. I usually go about a 2 weeks on one idea or new task killer and keep a close eye on battery drainage using Battery Monitor Widget, free app in the market. It tells you exactly how much of your battery is being drained without killing battery itself. Each phone/rom settles at a different average mA lower the better. In my experience if I can keep my phone anywhere under 100mA when idle im doing good. This held true on both the Evo 4G and my Sensation. Some ASOP roms i could get down to the 30's but for sense under 100mA is good. Keep in mind you will get the occasionally spike here and there its just android and/or apps in the background. You can view the a chart of the battery data in Battery Monitor.
Instead of boring you guys with each task killer Ive used and its results, Ill just get down to what I found out in the end.
Basically, the way android 2.2+ works it really isn't necessary to run a task killer it does a decent job removing apps from memory when you need more memory. But at the same time I found running a task killer periodically (BUT not killing frequently used apps) results in a lower average mA drain leading to overall better battery life.
The best application I have used has to go Automatic Task Killer , trust me Ive used a lot from the top free ones to a few of the more popular paid ones. What this task killer does is kill a selection of apps you allow it too every time your phones screen shuts off and goes idle. On Automatic Task Killer's first boot your shown a screen of every application that could at some point run in the background on your phone. This part sucks a little bit but it is worth it, you need to select which of the apps you want to allow it to kill automatically. It does not kill foreground apps the ones you currently have open on the screen aka a browser or a game. Example your playing NFS: Shift and your boss walks by so you quickly pause and hit the power button turning off the screen, next time you turn the screen on it will kill all other allowed background apps but your game will still be up front and center.
Now the trick is to go thru and set it to kill apps you know your phone won't automatically just restart or you don't use 90% of the time. So don't select things like Dialer, Contacts, Clock, Calendar, Messages or apps you constantly use/check such as a third party SMS app or your main E-Mail Client or third party keyboards (various by person and what you use most). Letting the app automatically kill those is just going to lead to worse battery life because your phone will just restart it each time leading to more CPU cycles (not what you want and part of the reason some consider task killers bad things).
Also, when using any task killer and killing the proper apps sense runs smoother, a big deal with sense 3.0.
So hopefully with a little messing around you can get a good setup where your phone lasts you all day without having to constantly keep changing settings and watching your battery life. All while everything stays syncing and instant. Hope this helps!
*ROOT Section (now that we have s-off )
Everything posted above can be done on any rom, rooted or none. There has been a lot of posts on "freezing apps" that you dont need or typically use, which does in fact really help battery life. Since, we (by we i mean sensation users) now have a permanent root this is my tiny second part of the guide for rooted devices.
I dont freeze my apps I prefer them to be gone for good if its something I dont see myself using or its bloat that came with my phone/rom. Since 98% of us will be using custom roms now this usually isnt an issue since most dev's r good at what they do and remove all the bs we dont need or normally use. Still there is some apps we may not want on our phones so for that I use SystemApp Remover . Its a great App for people who dont want to have to worry about going in manually and getting rid of system apps.
Its just basically an Uninstaller that allows you to access any and every app on the phone for you to uninstall (thats y roots needed). For me I just go in an drop the apps I know i wont use. A lot of roms come with carrier add-ons and such, those I normally delete as well as a few HTC sense widgets and apps I see no need for. It will free up space and increase your phones battery life with most things you delete.
Now, be careful. You are prompted upon opening SystemApp Remover that messing in system apps is dangerous and it is. If your not sure what something is DONT touch it, simply do a google search or ask around to see if its safe to remove first.
Re-calibrate Battery: After you flash a new rom or start using a new battery, you should use your recovery (CWM or other) to Wipe Battery Stats. Before you do this make sure your battery is at 100% and has been on the charger for over an hour with the fully charged green led on. This will allow your device to better drain your battery and can really help battery life.
So hopefully with a little messing around you can get a good setup where your phone lasts you all day without having to constantly keep changing settings and watching your battery life. All while everything stays syncing and instant. Hope this helps!

I use JuiceDefender, I like it. It manages my connectivity pretty well and it does help.
This is excellent, many thanks. As a converted WM 6.5 user I have to say, I am enjoying android considerably more and I prefer it to the Metro interface of WP7. It's nice to know the little tricks to get the most out of it. Thanks again. ^_^

Thanks for the info, and for sharing, i will try the different methods
i havent really bothered with task killers but ive found reducing the brightness and disabling data and sync makes my battery last alot longer. i just re enable when i need them.
also, i downloaded setcpu and added a profile for while the screen is off. that helps alot. the drain is about 5% with the screen off after every 3 or 4 hours.
Very good info thanks

Full version is much better.
It's killer app indeed. I think many of it's features should be natively included in android.
Options like "Turn off 3G/EDGE when connected to Wi-Fi", "Turn off all radios when screen is off", "Turn off Wi-Fi after x minutes if it doesn't connect to a network", "Set screen brightess to minimal when battery is low", etc....it wouldn't be that hard to implement and battery life, perhaps most criticized aspect of Android, would improve immensely.

Your mobile network DOES turn off when connected to wifi, and if all radios turned off when the screen went off, how would you ever get calls or emails with the phone in your pocket? The wifi after x minutes would be a nice feature, but I don't like things touching my screen brightness.
Thank you for your information.
my own original article with original thoughts for starting my first post on xda its also on my blog
Android technology is one of the exceptional operating systems of the world. With its great embedded features its quick and loaded. Billions handsets are running on this OS these days. Right from Eclair to ICS 4.0 all are great to use android versions of OS. But with certain brilliant embedded apps like google apps i.e. gmail,gtalk and some other bundled apps like facebook,twitter and other downloaded apps it becomes a rather heavy os and uses handset battery a lot.
Though Android OS is a revolutionary one but still it has shortcomings which we think Google will certainly with its innovative perception will make it more efficient in near future. Android based handsets are mostly run on either GPRS(3G)or WiFi. They are kind of internet based OS handsets. So it requires a constant use of internet on these handsets and that makes it even a more battery draining OS. Certain applications which we download from Google Play(app store) also uses the internet and battery in background. These are mostly free apps as because these are available to you for free but developers to have to adhere a cost on it and they try to recover it from inbuilt ad packages that some times becomes annoying for us while using the app or playing the game but we have to bear with it as nothing in this worlds comes for free.
Certain issues with android OS according to me are :-
1. Applications most free applications uses battery a lot as it runs in background and that drains a battery a lot
2. Some applications require a constant gprs or wifi facility to stay updated like facebook,twitter etc. again use of constant gprs will surely drains battery 40% faster then when gprs is off.
3. Sync problem every time you add Twitter,Facebook,Gmail of other social apps it tries to sync the phone book with it thus contact list become so huge even when you try to send a message you cannot differentiate whether its a phone number or an email of the contact your are selecting thus converting it to a multimedia message(Again battery is used to a great extent)
4. Location services running in background drains battery a lot as they use gps
with all these problems android still seems promising to me as it has changed the way mobile OS used to be. It gave mobile computing a new heights, with a use of gps,3g and wifi like services in a average looking handset.
To overcome these issue i have a made a checklist which you can follow to overcome these battery draining issues in your android handset:-
1. Always turn off your location services by turning of wifi and gps in settings will make your battery's life longer than usual.
2. Turn off GPRS and WiFi when not using internet so that your battery doesn't drains out quickly as it used to be as we know the major source of battery consumption is anytime activated internet services on OS.
3. Use a good kill task app as it will kill your apps running in background so as to reduce the battery usage for example Taskman etc.
4. If you like a free version of app and game try to buy the full version of it as it will come free of annoying ads thus will reduce your battery usage to a great extent.
5. Try not to stay login onto social apps for automatic login as they will run in background to keep continuously for resumption of internet services to sync back to where you left previously. I know its a bit annoying but a good way to reduce your battery consumption
6. Try to adjust the screen brightness to a an extent it makes your phone screen optimum for your eyes don't keep the brightness to 100% as it will drain the battery much faster.(Ideal would be to keep 50%-55%).
7. Last but not the least try to fully dry out your battery and then when your phone is switched off then plugin the charger for charging as it will reduce your battery usage and increases the life of battery.
These are few of my suggestions regarding the battery draining related problems in your android based handsets. I know we all love our android devices because of their amazing capabilities and multi tasking abilities as we know every good things comes attached with certain shortcomings though we have to bear them but still it is fruitful enough to enjoy. Try my suggestion will certainly make your android experience a bit better.
Hi there,
Nice first post. It's good to see folks contributing their thoughts. I do have some comments on a few of your suggestions...

The GPS-based location service doesn't actually consume any battery power unless an app is actively polling for a location - in which case you'll see the GPS indicator in your notification bar. Just go ahead and leave GPS enabled - again, it won't drain the battery when it's not being used. Additionally, in the unfortunate event that your handset comes up missing, apps like Lookout's Plan B require GPS to be enabled in order to locate your missing device.
2. Turn off GPRS and WiFi when not using internet so that your battery doesn't drains out quickly as it used to be as we know the major source of battery consumption is anytime activated internet services on OS.

Actually, I'm guessing that the number one source of battery drain on any given device under normal usage will be the display. Similar to the GPS, the radios don't use all that much power when they're not being used. A better suggestion would be to use wifi whenever it is available, as the wifi radio is much more power efficient.
3. Use a good kill task app as it will kill your apps running in background so as to reduce the battery usage for example Taskman etc.

NO. Task managers are a no-no. They interfere with Android's built-in memory management and cause way more harm (and battery drain) than any benefit they might provide.
4. If you like a free version of app and game try to buy the full version of it as it will come free of annoying ads thus will reduce your battery usage to a great extent.

Agreed, but more so just to help support the developers that create great apps and games.

This is good advice. Any app/service that is constantly or frequently polling for updates will use up juice in a hurry. Many of these auto-syncing apps will have a configuration option for how frequently to poll. Try perhaps every half-hour rather than 10 minutes for email, and 3 hours rather than 1 hour for weather.
6. Try to adjust the screen brightness to a an extent it makes your phone screen optimum for your eyes don't keep the brightness to 100% as it will drain the battery much faster.(Ideal would be to keep 50%-55%).

If you're saying here what I think you're saying, this is also a no. You should never (or at least rarely) let your device drain all the way before charging it. At least with the popular Lithium Ion batteries, "If at all possible, avoid full discharges and charge the battery more often between uses." (source)
number 4
just install adfree if you are rooted user.
But i read @ sony forum that draining to full atleast once a month and frequent charging ( wont affect battery life) will help the lasting of battery ( from the forum staff) which way we go now?

It depends on the technology of the battery, really.
And there is some benefit to fully draining an Li-Ion battery, as it helps with calibration so the OS can more accurately measure the battery's state. It's certainly not something you should do every day though.

5. Try not to stay login onto social apps for automatic login as they will run in background to keep continuously for resumption of internet services to sync back to where you left previously. I know its a bit annoying but a good way to reduce your battery consumption
6. Try to adjust the screen brightness to a an extent it makes your phone screen optimum for your eyes don't keep the brightness to 100% as it will drain the battery much faster.(Ideal would be to keep 50%-55%).
7. Last but not the least try to fully dry out your battery and then when your phone is switched off then plugin the charger for charging as it will reduce your battery usage and increases the life of battery.
These are few of my suggestions regarding the battery draining related problems in your android based handsets. I know we all love our android devices because of their amazing capabilities and multi tasking abilities as we know every good things comes attached with certain shortcomings though we have to bear them but still it is fruitful enough to enjoy. Try my suggestion will certainly make your android experience a bit better.

Out of the 7 points which you have given, after reading the 2nd point, switch off the phone and throw that away, thats the best think we can do.
Everywhere , almost everywhere this is the solution given to save battery, if all features ( atlast the basic features ) are meant to be turned off, then why a Smartphone ? Nokia 1100 phone is better. I will wait for somemore time on android, and next I will defintely to switch to iOS, atleast its using the battery while we using the phone, not while sleep.

I have an S22 Ultra 128Gb on Verizon and the battery life id absolutely horrible. The pictures below will.show my average and my battery for today, could really use some help to fix this (ive had the phone for about 2 months now)
Pretty obvious to me that Life360 and USAA SafePilot are using a lot of battery. It's probably because of the continuous GPS tracking. Unfortunately if you have tracking apps running in the background 24/7 you can't expect a decent battery life. Here's some suggestions to improve your situation:
1. Get rid of the tracking and SafePilot apps altoghether, this would make the biggest difference;
2. Try to find alternatives to these apps that consume less juice;
3. Within the apps, navigate the menu and check if there are options to reduce accuracy or extend the period between tracking pings;
4. Reduce GPS accuracy, if allowed by the apps to keep working, by going to Settings-Location-Location Services and disable Wi-Fi Scanning and/or Bluetooth Scanning, then in the same menu tap google location accuracy and turn it off. All of these, of course, will decrease the accuracy and responsiveness of tracking;
6. In Device Manager, go to Battery-More battery settings ad toggle ON Adaptive battery. This for sure will save power but you have to let it learn your usage for a few days, give it a try if it's disabled and wait for about a week in order for it to be effective;
7. Check your nework (4G-5G) availability. Sometimes a bad battery life comes from bad signal. If you have bad signal in the areas you normally are, then consider changing your network provider;
8. Turn the Processing Power to Optimized or High;
9. Keep the phone away from warm environments like the car dashboard;
10. Try to not use the phone while charging;
11. Get rid of all the apps you don't use. Some apps, even if not shown in the battery resume, can drain small amounts of juice but combined can make a noticeable difference. A good (BAD) example of this are in your case the Facebook and TikTok apps;
12. Last resort would be a full device reset, starting from scratch and not importing your backed up settings. It can be a long and frustrating process but, given that you can always restore all your data if you make a backup, it can solve some underlying issue that is not easy to identify;
13. Keep your phone always updated, specially for a new device as the S22 Ultra the first updates make a huge impact on power management;
14. Try to harge your phone before going to bed, unplug it while sleeping and eventualy top up in the morning if you need that few extra percentages for the day; furthermore, is in general a good idea to keep the battery percentage between 20% and 80%, don't get to 100% if not strictly needed and start charging as soon as you are approaching 20%, of course if it's possible at all; in the medium-long term, this makes a huge difference on battery health;
Even if you do a lot of these things, don't expect your battery life to double or something like that. You are having a pretty bad battery life but it's not tragic as I can see you get a full day of usage. It's for sure possible to improve it!

I did get rid of the safepilot for a little to see if it would have an effect but it didn't do much from the looks of it
