I just unlocked my phone by 'interop unlock method' and loaded a few homebrew apps on my samsung omnia w.
now ever since i've done that i'm getting wierd battery life.
battery life finishes very quickly and sometimes just switches off when i reach around the 20% mark directly going to zero.sometimes from full 70% available i becomes 10% within seconds. i am suspecting the battery status homebrew app and have also uninstalled it without any solution to my problem
anyway to fix this without having to reset my phone???
Battery: making it last
There's a lot you can do to make the battery in your Windows Phone last longer between charges. The easiest way is to use Battery Saver. You can set it so that it'll turn on any time your battery gets too low, or if you know in advance that you're going to need to make every bit count, you can turn it on to make sure your battery lasts as long as possible.
When you turn on Battery Saver, your phone automatically turns off some of the features on your phone that use battery in the background. So when Battery Saver is on, your phone will no longer:
Automatically receive emails or calendar updates – You can still sync your email manually whenever you want. To learn more, see Synchronising your email.
Update some Live Tiles – The technical explanation is that if a Tile uses something called push notification to get its updates, it'll stop receiving those updates in Battery Saver mode. But the upshot is that when Battery Saver is on, some of your Tiles won't be updated.
Allow apps to run in the background – You'll only be able to use an app if it's open.
You can still make and receive phone calls and text messages, and browse the Internet.
We've also put together some battery-saving tips to help you get started. The key is finding the balance between getting the most out of your phone while getting the battery life you need.
To turn on Battery Saver
On Start, flick left to the App list, tap Settings Settings icon, then tap Battery saver.
Do one or both of the following:
If you want Battery Saver to turn on whenever the battery gets to 20%, select Always turn on Battery Saver when battery is low.
If you want to turn on Battery Saver now and leave it on until the next time you plug in your phone, select Turn on Battery Saver now, until the next charge.
When Battery Saver is on, the battery icon looks like this: Battery Saver icon
Note
When Battery Saver is on, you won't be able to change the settings for features that are disabled (like email, for example). To change a setting, go to Settings > Battery Saver and clear all of the checkboxes. You can turn it on again when you've finished.
Here are some more tips to help make your battery last.
Reduce the time before the screen turns off
Set a shorter Screen time-out duration and set your phone to lock. This helps save battery power and also prevents your phone from turning on by accident when you put it away. For more info, see Lock screen FAQ.
Lower the brightness setting
On Start, flick left to the App list and tap Settings Settings icon. Tap Brightness, turn off Automatically adjust, then select the Level that you want to use instead.
Use a dark background theme
On Start, flick left to the App list and tap Settings Settings icon. Tap Theme, tap Background, then tap Dark.
Sync music and pictures on your computer
When you're on your computer, connect your phone and sync your favourite music and pictures to it using the Zune software. To learn more, see Synchronising music, pictures and videos . You can then enjoy your favourite pictures and songs on your phone, even if you're in an area with poor reception.
Of course there's a lot of music out there that might not be in your collection, and streaming lets you enjoy new stuff while you're on the go. But if your battery is running low or you can't get to a computer or a power source, avoid streaming music for long periods of time because it uses more power. If you listen to your playlists with the screen turned off, make sure that the current playlist doesn't include streaming items. And if you're not a Zune Music Pass subscriber, you can turn off Connect with Zune in the Music + videos settings.
Turn off connections you're not using
When Bluetooth is turned on, your phone checks continuously for available accessories. So if you're not using a Bluetooth accessory, you can turn Bluetooth off. For more info, see Pairing your phone with a Bluetooth accessory.
Also, if you listen to music or talk on the phone for hours, try using headphones instead of a Bluetooth device. And if you are using a Bluetooth accessory or the speaker in a call, press the Power Power icon button to turn the screen off. To learn more, see Making and receiving phone calls.
Not using games at the moment? Then you can turn off the Connect to Xbox LIVE setting in the Games settings.
Sync emails and contacts selectively
To make your battery last a little longer, try one or more of these sync-related tips:
Change the sync settings for your email accounts to a longer interval, especially for secondary accounts that you don't need to check as often. You can change the sync setting on a per-account basis. (On Start, flick left to the App list, tap Settings Settings icon, then tap Email & accounts. Tap the account that you want to change the sync settings for, tap Download new content, choose a longer interval, then tap Done Done icon.)
If you don't use any Windows Live services and don't have an email account hosted by Microsoft, such as a Hotmail account, go into the Windows Live account settings and change the default sync setting to Manually.
Choose which contacts are synchronised to your phone. If your email account doesn't include any contacts that you want to keep on your phone, you can choose to not have them synchronised to your phone. You can also keep your Facebook contacts separate from your other contacts too, which should help reduce the total number of contacts synchronised to your phone. For more info, see Social networking on your phone FAQ.
Be aware that each time you visit What's New for People and Pictures, your phone uses extra power to sync and update.
Picture-taking tips
When you've finished taking a picture, press the Back Back hardware button button to exit the camera viewfinder. (You can also press the Power Power icon button to put your phone to sleep.) When the viewfinder is active, the screen stays on longer.
Also, when it's time to upload pictures, only upload the ones you want to keep and skip the ones that aren't so great. This saves power, and saves you time later when you want to sort your pics at your computer.
Warning
Do not remove or replace the battery when the phone is turned on. If you have a spare battery, turn off your phone, then replace the battery in your phone with the spare. This helps ensure that your data is saved properly. To turn off your phone, press and hold the Power Power icon button for three seconds until the goodbye message appears and the screen goes dark.
i know about these tips. but i have never followed them. phone functionality becomes limited.
appreciate the help.
but is there a known homebrew app which messes with the battery registry??
because there was no problem before i hacked the device

This is why every developer insists on backing up ur device before unlocking or using any of their apps..
Even I was getting around a full day of battery backup time on browsing for half an hour,playing xblive games for half an hour, music for half an hour, calling on 3G for half an hour a day when my omnia w was new..now i get some 15hours..
Anyway most probable cause may be u have left the bluetooth turned on unnecessarily..or may be too many background apps are running..if this is the cause, goto settings, flick left/right, goto background tasks and turn off all unnecessary apps running in the background..and dont forget to turnoff bluetooth after usage..And dont overcharge ur battery, stop charging after it reaches 90-92%..

I experienced a big decrease in battery life when using a certain custom ROM, a different ROM was a little better, but I returned to stock, which was quite normal again

I have reseted my phone twice from Settings>about Phone.
i have already looked at the background settings and turned all of them off. i even turned it off in heathcliff's root tool(used interop unlock).
bluetooth was never on in the settings menu (though the option for "audio via bluetooth was toggled on in wp7root tools". but i assume it doesnt keep the bluetooth on)
-What happens is my battery shows a charge of @ 50-60% few hrs after removing from charger and then suddenly the sound for low battery plays and it "goodbyes". and doesn't turn on again. it directly goes to 1% charge and turns off!!!
-yesterday when i rebooted my phone: at the moment i switched off my phone it had 80% charge, but when i booted back on it became 1% and turned off by itself !!
something is messed up
what should i do?
EDIT: going to hard reset using *2767*3855#
after first reset
all i did was use custom accent colour after heathcliff unlock in his tool itself.
still the problem persisted
quite a few tweaks like audio via bluetooth and 3g toggle,etc don't work at all in the wp7root tools for me. they get resetted back whenever i change them and reopen the app

Just take a look at the battery terminals..i think ur battery is out..just check if any of ur frnds have a samsung exhibit 4g/exhibit 2/focus flash/transform ultra/conquer 4g..their battery fits perfectly into ur phone..just to check if culprit is the battery..if inserting their battery solves the problem, ditch ur battery and get a new one..on ebay u can get a 2500mah battery for 10USD instead of samsung's 1500mah one..As far as windows phone devices are concerned,that to 2nd gen samsung devices a hard reset(from settings>about) should solve problems like freezing on app launch, not connecting to marketplace AT ALL, etc.

Any other way i can test the faulty battery??
the link you gave don't ship here in india
- The phone doesn't seem to be reading my battery properly. are you sure its not a registry issue? Because sometimes it turns off at 50% charge but when i plug the charger it says 50% remaining. the battery is just being read wrong. is this because i unlocked my phone?
EDIT: Did a research and have noticed that my battery has swollen and http://www.jesoba.com/2013/02/all-you-need-to-know-about-cell-phone.html this guy has same problem as me.

I'm going to buy that one but I don't trust the seller yet. I'm looking for alternatives. I'm in touch with the seller and I am currently corresponding with him. this is the last correspondence with him
"sir. for electronics.. I generally don't accept returns because I don't see how the product was handled after the purchase. some ppl ask for returns after they have mishandled the product. hence I cannot take returns .sorry. but if you receive a dead product then certainly you can send it back.
also please note there will not be any product packaging for this just a polythene bag to avoid any damage during transit.

What kind of seller sends it "in a polythene bag" without packing "to avoid damage".

Many sellers send such third party items which are small in volume in a polythene bags..that is tragic..but u can't help..according to my experience, a nice thick polythene bag is enough to support the battery against simple damages like scratches..leave alone battery..i had got a screen protector in a polythene bag..which is really heartbreaking..so cheer up and pray god ur battery won't get mishandled..

Hoping someone might be able to help me here..
Within an hour of being taking off the charger (and confirming it was 100% at that time) my battery life is down to 80%.
What's happened so far is:
1) alarm went off (set to ring only - no vibrate)
2) recieved 2 emails on yahoo (set to check every 60 mins)
3) received 1 push email through exchange/active sync
4) 1 calendar appt reminder.
The screen has probably only come on 3 times for no more than 10 seconds each time. My brightness is set to the 2nd lowest level possible. My ringer is on the highest.
Here are the apps I have installed. I have not "launched" any of these today.
.net 3.5
Easy Shares
Google Maps
Microsoft My Phone - (set to sync once at 3am & was on charger then)
Mobil manager for netflix
S2U2
Waze (another GPS app)
Phone is about 4 weeks old.
download HD Tweak and set up data disconnect after to 1 minute. I am almost positive your data is staying on after downloading email because i had the same problem with my Touch Pro. Keeping the data session open is a huge battery drain
My battery life is terrible too! I charge it fully throughout the night and the phone typically dies by the time I get home from work at 6PM or so. I barely use it at work. Never talk on it. The occasional text message. But by the end of the day the phones dead. I have no idea why. I know for some odd reason by phone will not automatically go into sleep mode. It should, but doesn't. Not sure if that kills the battery even though I manually push the sleep mode button each time.
I set up the HD Tweak software. We'll see if this helps. Does it work for the Touch Pro 2 also?
Any of you guys using a case with a magnet on it by any chance?
Possible explanation...

Just curious, did you charge the phone while it was on? If so, I've found it a problem. I once charged my phone while it was on, and I took it off after about 2 hours (the green LED indicator probably showed up an hour before I took it off). I checked the battery meter and it registered at 89%! I found out that there's a flaw in the way the found charges. Once the LED turns green for a full charge, the charger cuts off, but (I think what I'm about to say might be true) the phone thinks it's running something as it charges, thus causing the rapid battery drop.
Since then, I stopped charging my phone while it was on. I now turn off the phone and then charge it. I can last a whole day with about 45 minutes total on the Internet, and my battery would go to about 60+%.
However, as jaas666 pointed out, are you putting your phone near a magnet? The magnet tricks the phone into thinking the stylus/keyboard is being pulled out, thus causing it to wake up, which will drain your battery.
Have you tried a task manager to see if a program is running when it's not supposed to?
http://www.dotfred.net/TaskMgr.htm
I had terrible battery life and found two issues. One program was always taking up around 10% CPU usage (VZO video chat software). Also found that Google Sync, set up through ActiveSync, was having trouble. I'd open ActiveSync and find it in a synching loop. For me the solution was to untick "Tasks" in the sync menu. Since then, battery life has been great.

HD Tweak works fine on mine, I've also heard of some people using Diamond Tweak. I mostly text all day maybe some internet but I have gone a day and a half without charging and even then my battery had only gotten to ~20% so I think with a few changes it could be fixed. I'd check out some of the Tweaks threads here and at PPCgeeks for registry edits u can do to save the battery too
I had those issues with my 2000mAh battery on my sprint tp1. With my verizon tp2 my battery life is fantastic. I use the crap out of it all day also. Was wondering if the bad battery life is happening mostly with sprint users.
I have my active sync connected at all times for wireless email calendar task syncing. I charge with the phone on all nite long and the battery drains only slowly throughout the day. Less than 50% today. It is on 24/7 I never shut it down unless I'm soft resetting due to a file or app install. I use my ms3.5 task manager to keep stuff closed after using. I always put it to sleep mode by the button when I'm done with it. My screen is set to brightest and stays on 2 min. before sleep mode engages unless I manually do it.
I'm sorry to hear your battery issues, my tp1 with sprint was really hard on battery juice. I found it would struggle to find a signal alot, one reason I switched to vzw.
Hope you figure it out.
Sad to say that my less than 4 days old Sprint TP2 is disappointing to say the least in battery life and all around usability. Now i'm coming from a Treo Pro and so used to one handed operations and such. But i digress...
Battery life on this beast is sad, really sad. Someone alluded to Gmail Exchange ActiveSync as a potential battery drain so i might look into that. Basically i'm gonna hard rest and start from scratch applying less tweaks. Basically i find TF3D tedious really..takes too many steps just to do some basic things. I turned it off and managed better a bit but i just might go back to my Treo Pro and sell this thing..
My battery "appears" to drop quickly, but actually hangs in there quite nicely. My old phone only showed me 20% increments, so going to 1% makes it very noticable.
I ran cleanup first thing, then went back and customized.
I use Activesync in push mode (7 days per week 8am - 9pm), have it checking Hotmail, stocks, weather every 30 minutes. BT is on, Data on, WiFi off. I even went back and turned auto screen back on as I couldn't read cleanups default change in the sunlight.
Gets turned on at 7am, and at 10 pm I'm ussually 30-40%. Medium user - 40 minutes phone use daily, 1-2 hours total IE time, ALOT of email checking, hardly any SMS.
I do use a magnetic holster too. S2U2 fixed that issue.
Biggest drain I noticed is screen. If I turn off auto and go back to CleanUp default, I can get through almost 2 full days if I turn it off around 11pm, and back on 7am.
And as far as battery total use, my older phones always turned themselves off at about 15%. THIS THING WARNS ME AT ABOUT 4% and turns off 2-3%! That's alot of extra battery use.
There is a company making a 1750a battery that will fit in stock case.

Not sure if this will help you but some phone cases can cause battery drain. Read here:
http://forums.wmexperts.com/showthread.php?t=175441
Okay, I have an Imagio (please don't judge me ) and like many of you TP2 owners, the only real complaint I have about the phone is the battery life.
For me, I rely heavily on the device as a phone first (no big surprise, right?), email second, and then text and internet. Based on how I use my phone, I think the biggest contributor to my quick battery drain is the fact I have to leave my data connection 'on' to auto send/receive email.
I'm interested to know if there's a tweak or something out there that would allow me to leave my data 'off', automatically turn it 'on' to send/receive email at my specified interval, and then turn it 'off' again once completed. I know I could do that manually but was curious if there's something out there that could run in the background.
Also, thinking about it, has anyone looked into changing the weather tab uppdate time? I'm also wondering if the weather sync feature is sucking battery power?
Ok, my TP2 with Telus I have on data all the time, with push email (so more frequently goes active) and have no problems at all with battery usage. I can go several days between charges, but don't because I plug my phone in every night anyway.
How much talk time do you have on the phone on an average day? How many emails do you recieve? Is it exchange based on POP/IMAP?
You can easily set up the email sync itself to be manual, i.e. open your email app and click on send/recv - this way it won't hop on itself to grab emails all the time which will help with your battery life, but not really by much.
Similarly just set the weather application not to update automatically.
Keep in mind that a single phone call (on average) lasts about 3 minutes, a single data session lasts only a few seconds.
But even if you still want it to send/recv at a specified interval then when the connection is dormant (i.e. in between scheduled send/recv) it's not really taking any more power than if it was "offline" - this is just a state that both ends know, not an always-active transmit/receive when there is no actual data.
If you really need more battery life then just wait a few seconds when you check your email or the weather for it to go online and grab the data on demand.
Thanks for the reply Telek. Since I've had the phone, my talk time per day has been pretty low, relatively speaking. I seem to notice the drain after the phone's been sitting idle. I charge daily but if I didn't, I'm guessing I wouldn't come near several days on a single one.
I do get poor reception while I'm in my house and I'm thinking that might have something to do with it. What you wrote about the data connection while inactive makes a lot of sense - I should probably be looking elsewhere.
Also, my phone is set to CDMA only in case any viewers are thinking of asking the question.
Well poorer reception will hurt battery life, but only while the phone is active. CDMA signals all have to reach the tower at the same strength (IIRC) so if a phone has poorer reception it will have to up it's broadcast power.
How many emails are you getting daily? Is it feasible to just go to "on demand" and manually do a send/recv to see if that helps your battery life?
It's possible that the phone isn't going into sleep mode, or times out at a much longer interval than normal. Perhaps try going into the power management page and shrinking the timeouts?
Not sure what else to suggest - maybe you just have a bad battery?
I am in the same boat here. Although I use pop and don't get that much email. I use it as a phone, text, then data. Just through a days use, sometimes not making a phone call at all my battery will be near death. I HAVE to charge it daily. I have a car charger, charger at work, and 2 chargers at home so I always can charge so it isn't that big of a deal for me. My signal strength is normally above 70% through my house and work.
I am ready to try out a new rom to see if that makes a difference.
PS not trying to thread steal but throwing out some info that might help.
I have to charge my TP2 like 3 times a day. Between Twitter, email, and reading on the net it goes pretty fast.
My battery life isnt too good either...I have email set to check every 2 hours. If i browse the net for about 15 minutes I lose a notch in battery life. I have to charge every night too!!
I got the 2100 extended battery in the mail today, im going to try it out and see how it does...if it's not a big improvement then im sending it back...the extended battery cover is ugly and slightly bulky so I dont like that to well...
Has anyone fooled around with the power management settings in ATC? If so, any notable changes worht exploring?
Well for my usage on a Sprint Touch Pro 2, I get good battery life. I make maybe 10 calls a day but each call is less than 2 minutes.
I surf the web maybe an hour a day and send + receive maybe 75-100 texts a day. I dont check my email to often.
Maybe 3 times a day I press Send/Receive but after I finish my stuff, I go to Communications and turn off my Data Connection.
At the end of the day I have about 60%. Although I have my backlight set at 30%. Others like it halfway and others fully set.
30% is ok for me indoors but once outside I turn it up to 80% if I really need too but then set it back to 30% once indoors.
Some solutions to Imagio battery drain
My 1st Imagio had no problem with battery, but the "end" key broke so I had a replacement sent. The replacement had nicks on screen and major battery drain, with overnight charge, by 3:00pm I had 5% left. So I sent for 2nd replacement. Same problem with the battery, fully drained by midday. Frustrated, I went to Verizon and requested replacement battery. All seemed well at first. Then, the new battery began to drain. I started eliminating programs running and now, at 10:00pm, I still have 72%, I talked, texted, sent pic mssg, got email, updated weather...etc. This is what I changed.
I turned the phone to CDMA only.
I changed input back to default HTC qwerty (I had sip change to swype)
I set email to check once a day, but I hit send/receive periodically
I set weather to check once a day.
Sorry, but I also uninstalled "codyppc performance booster"
I reinabled Auto Divice lock. (this seemed to help save battery by locking)
I am running spb mobile shell 3.5 and WM 6.5 interface. Whenever I run the HTC Touchflo3D it seems to drain more battery, along with suck up memory.
I check running applications often, reset a couple times a day. I am having an issue with my spb time alarm going off in the morning though. I will try something tonight to eliminate that as the culprit. Overall, I think anything set to run regularly will drain the battery. With these fixes, now I LOVE THIS PHONE. I have all my programs on it, lots of program and storage memory left, (more than I had out of the box) tweaked just the way I like. Hope this helps someone.
Please don't forget Clean Ram(search xda) , helped me alot.
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.

Thank you very much
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

You should go through a battery recalibration - steps on the first page.
Best Practices for Improving Battery Life for CM 5.0.7 (and variant ROMS) is to use this ROM, Thanks.
Do whatever you like, show or hide battery status in the Spare parts, calibrate or not....the battery remains....for loOng....enough time....
hot/cold controversy

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
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
Sent from my Milestone XT720 using XDA App
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.

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!

u da maaan dude, thanks for a very detailed and informative article
Hello everyone!
I was just wondering between these two apps...
Which one works better for you and if will be great if you can share your configuration!!
Also, does anyone knows is any of these two disable whatsapp and gmail notifications?
Many thanks for sharing!
Cheers!
IMHO
I can answer about Green Power Premium:
It doesn't have such option like disable notifications. He does such thing like disables data connection for amount of time you chose (for me it is 15min) and then enables data connection for amount of time you choose (for me it is 2min)
Now my Galaxy Note works 2 times longer (from 10h to 20h)

WOW! double time!!
thanks for sharing!
I have been trying both, and while both of them seem to deliver a noticeable reduction in power draw (actually in my case a dramatic reduction), of the two I'd have to give my vote to GreenPower (I'm using the full version). The power reduction is at least as good as Juice Defender Ultimate, and the premium version is significantly cheaper.
Both work by turning various features (mainly Wi-fi/3g/BlueTooth) on and off automatically, but as result can cause delays in things like receiving push-mail and that kind of thing. With Juice-Defender I found this to be quite noticeable, but I'd have to say that with Green-Power I haven't really noticed it slowing down messaging or anything else.......
I've used them both - and deleted them both. I'd rather manage power myself.
i am using 2x Battery for me this is the best. simple and clean.
I usually use JuiceDefender but decided to try out Green Power. I really like it but I have a hard time getting my phone to sleep properly on GP.
i use widgetsoid and just enable my connection when i want it (wifi/3g)
i could never find the proper app that did exactly what i wanted- rather just have control.
going that was and using the phone an average amount my battery goes from 100 -> 75 from the time i wake up (7am) to the time i got to bed (12-1 am)
the 2500mah battery is pretty good!
With JuiceDefender I can get my phone to sleep 95%+ of the time but with GreenPower, my cpu is only sleep 40%+. Can anyone give me tips to get my cpu to sleep more to preserve battery?

Just out of interest, what happens when you browse the web and GreenPower has turned off the Data Connection?
Or you're watching a youtube video and it decides its time to turn off data?
Tried both versions and found green power premium to work better for me. (Price was a good point too.)
However the next day I found that if I left my phone for a while (Around 1 1/2 to 2 hours), the display would not turn on and If I called the phone it would not ring. Only way to fix this was to press the power button for 10 seconds to reset the phone.
Uninstalled green power to see if this was the cause and hasn't happened since.
Was wondering if something similar has happened to other people?
I had to go back to JuiceDefender since I couldn't get my phone to go into deep sleep with GreenPower.
Hi, i went for Green Power. I found it simpler to configure, more focused on the job. Juice Defender has to much possible settings and complexity, this makes it a great tool but might also lead to poor efficiency.
I have never used green power before but im on juice defender. I have experienced auto turn off by the note due to a set cpu settings that govern lower clock to cpu at a certain condition. Due to the big display on note i think lower cpu clock wont do it. Because of that the device turned off itself. Upon failure to operate. Hope this solves your problem
I have tried JuiceDefender but ultimately prefer to do everything manually. Some how I always feel the auto manage apps will have everything off precisely when you need it. I use the SwitchPro widget to quickly enable/disable the various radios from my home screen and it works great.
@ Aldragor
I have/had the same problem. In the beginning I thought that my launcher would be the cause for this problem, but after I disabled my Green Power Premium it hasn't happend since now.
Juice defender ultimate, the feature of switching 2g 3g on stock ROM alone was worth the price!
After figuring out how to config GreenPower properly, I went back to it.
I used JuiceDefender and thought it was great.... when it worked. However, I used it mostly as a scheduler with about 15% battery saving which I took as the icing on the cake.
I want all connections on during the day (peak) so I can take skype calls, etc.. When I'm home, I just want to periodically check for mails, etc (so have connection enable every 15min) and when I go to bed I don't want to be disturbed by emails, messages, etc but still want phone/sms on in case there is an emergency. And most of all, I didn't want to have to manually do that every day.
Problem was that it never really stuck to the schedules. This was the ultimate version but it was a crack as they never offered the ultimate on a trial. I wanted to evaluate the ultimate and buy if it did the job. So, it might have been a bad crack which caused the problem, but I guess I'll never know as I don't want to risk wasting the money if the schedule problem persists.
I am a lover of juice, it keeps he juice in and right
