Steps To Twenty Hour Battery Life

Ok I have been reading since literally the first day the G2x came out about the "Horrible" battery life of the phone. So, after toying with it for about 8 days I have nailed it down so that the phone gets about 20 hours of Moderate use(Constant texting, internet for emails, YouTube, and searches, and probably about 2 hours of light gaming(not Nova or NFS)). So, Outside of the obvious like make sure your bluetooth, wifi, and GPS are off and turn your display brightness down here are my steps to Better Battery Life.
First - Root The Phone. There is plenty of links and help if you don't know how or have questions about rooting.
Second -(Root Needed) Use Titanium Backup or Antek App Manager(Antek is free) and Freeze or uninstall all the bloatware that you don't use off of your phone. Especially Car Home cause along with people on XDA i have also noticed that it does use a fair amount of battery for NO Reason.(Be careful with My T-mobile and My Device might throw your phone into a force close frenzy)
--For some reason people have been asking exactly what T-Mobile Apps you can freeze/uninstall and the answer is. All of Them. I personally left My T-Mobile(To view Minute Usage) and Wifi Calling(Cause I have no service in some buildings) and froze the rest, but you can get rid of everything you don't want or use.
Third -(Root Needed) Set CPU. Have had this on my G1 and N1 and it does nothing but save battery. I currently have it set on 216 - 1000 for when the screen is on and the only profile i have is for when the screen is off and it is at 216-216.
(Alternative) Pimp My CPU. I now am using this for my G2x because I am running custom kernal. Personally I like Set CPU better, but do to the fact that Set CPU can't get past 1000 MHz makes it kinda useless for the G2x Tegra 2.
Fourth -(Root Needed) Battery Calibration. There is an App in the Market for this and it is easier and less of a hassle than Factory Reseting the phone. Just charge all the way to 100% and i discharged to 0% and recharged it and Amazing difference in battery life. (And don't doubt the Calibrator cause right after i set it to calibrate the initial 100% got to zero in about 7 hours, but after that one cycle i was getting the 20 hours i am now)
Fifth - Elixir. Not only does this app display anything you might wanna see about your phone (CPU usage, battery temp, battery percentage, memory...) it also has a widget that lets you toggle your internet on/off. Which is almost necessary since "4G" kills battery like no other.
Sixth - Auto Sync. I shouldn't have to put this, but if you don't know your phone is set up to auto sync all your Google apps(Calendar, Gmail, Contacts) and Social Network apps(Facebook,Twitter). So go into settings and make sure that you turn auto sync off.
Now the next steps aren't proven to give extra life, but i did them just in case and well I get 20 hours of use like i said before.
Sixth - Watchdog. This app monitors all the other apps and processes in your phone and will alert you if a rogue app is draining your better life.
Seventh - I did the "Alternate Battery Fix". This involves changing one setting and who knows maybe it does help me get extra juice.
Link: http://forum.xda-developers.com/showthread.php?t=1051036
Eighth - Wifi Never sleep. Supposedly according to some if you change wifi to Never Sleep it will stop some loop in the programing which in turn will save battery.
Ninth - Wifi Calling. If you didn't decide to freeze/uninstall this app. Make sure that this is OFF, because whenever you have wifi on it will constantly flip between Wifi Calling and normal radio towers, which once again is bad for your battery life.
Well, Thats that and if y'all can think of anything that i missed or have any questions or ideas let me know! And remember this is a Dual-Core, High-End, Monster Phone and duh if you use it hardcore (Movies, HD Games, tons of web browsing) the battery will die fairly quick.
P.S. Will post a Screen Shot of Uptime for 20 hours later(if it doesn't Re-boot before i get to 20)
Update #1: Have read all the posts and have decided to speak up about a couple things.
Task Killers - I feel like these are brought up in every thread ever created about batteries, and well they are useless. So, if you are gonna bring up the ram usage argument. Android is made to kill programs that are either inactive for to long or the operating system will shut down background tasks if a new app needs the cpu power. Than for those who say that it helps close programs and makes the battery last longer.Having a Task Killer that basically re-closes the same apps over and over again(These are usually bloatware background apps that for some reason never stop running) is not gonna do anything except waste precious battery life on running the task killer itself cause the app will just restart. Your best bet is to run watchdog find the apps that are taking to much battery and freeze/uninstall them.
Managing Apps - Apps like Tasker, Juice Defender, and the like are in my opinion not battery savers at all. They are just tools to implement what i have already previously stated, but that doesn't mean that they aren't useful. They are good if you have a busy schedule and have to constantly turn the internet on and off or switch between certain settings, but they are not actually a cause of better battery just a tool to implement what you could do on your own.

I've done most of those things over the course of the last week and I just got a little over 24 hours on my last charge.
Those tips are legit.

Thanks! I was kinda worried about it cause it was my first post!

Great job! I've been getting about 20hrs of battery life using some of these... now I have more tricks to add =-)

Good job! I'm almost done withall the tweaks and have say it helping. Thanks

Great tips. I was doing most of those, but have added the calibration software as well as watchdog. I have also found Juice Defender to be a big help.
Thanks again.

this is still not acceptable for a phone in 2011 to still have that kind of battery, most people out there aren't really concerned about tweaking their phones or dont even know about it. Im not gonna use setCPU or anything else, i expect things just to work flawlessly out of the box.

Tasker can be a friend in this whole deal too.
If you can automate your radios & screen brightness to exactly what you need when you need it you can save significant battery life.

If your WiFi calling app can't stay on wifi, you need to fix your wifi network and not your phone.

With all of these changes having a toggle for haptic feedback I assume would help a ton...considering its a touchscreen and a retardedly fast phone. Otherwise it vibrates on every damn user input. Just curious what others think about this. Anyways, thanks for this post....the forum is getting congested.

Yeah, but on the flip side your an early adopter for technology that literally JUST CAME OUT and so there is no perfected system for it. I mean the version of android we are running right now doesn't even truly support dual-core! So yes this is the price we pay, and if dual core had been out for two years I would completely agree but it hasn't. This is what android has always been built on a semi flawed system but top of the line technology and thanks to the great community we have we can push the limit of every device out there even the g1.

I meant this for people like myself who live in an area ( or college like me) where you are constantly moving in and out of wifi range and that would take a drain on your battery.

I think the reason we have so much haptic feedback though is because we are lacking physical buttons and the small vibration gives us the sense of a solid keyboard even though as you stated everything is a touch screen. Well that is my 2 cents anyway.

I will definitely look into tasker and check it out personally and add it to the list later! Thanks!
Update: I have seen programs or apps like this before many moons ago i used a program called wisyncplus and basically it is just profiles. This I guess could be used to increase battery life, but in my opinion apps like this and Juice Defender and what not are simply 1) too much of a hassle - cause you have to usually set up each profile individually 2)This is more of a convenience - It doesn't actually increase battery life it is just a manager almost like a widget.
Than back to your argument about the screen brightness my auto-adjust does just fine depending on the lighting and honestly in less your watching a movie, playing video games, or doing intense web browsing your more than likely not even gonna have your screen on that long. (and to those of you that say the Auto-Adjust doesn't work remember that this is an LCD screen it is lit from behind so it is gonna seem brighter unlike the Nexus S which is lit in the screen making it viewable with less brightness)
Than for automating radios honestly there is already widgets for that. The stock rom comes with a Wifi on/off widget so no complaints there, and elixir(which is a free and very useful app) comes with a apn off/on widget which is really all you need cause in my experience unless my internet is on I see no difference in battery life being GSM preferred over WCDMA preferred.
So in less you really do have a tight schedule, or just don't wanna mess with changing settings manually(and with widgets), Yes, Tasker is perfect cause it basically does everything for you.(even though i am pretty sure there are free apps exactly like Tasker)
(Sorry if this came off kinda rude I don't mean to flame at all just trying to say all of my opinion and back it up as best i can)

if this is the case, i don't think that an open-source phone is for you. the beauty of android is that anyone can personalize it and tinker with it.
the g2x is sort of like a muscle car- it has lots of [dual core]power, but the trade off is trying to manage battery life.

For the sake of min/maxing battery drain I would think toggling the vibrate after every input would help. I actually like the keyboard without it pulsing all the damn time. And my hearing might be a little sensitive to where I dislike the fart sounding vibrate motor. Haha.

Couldn't have said it better myself. This is exactly why I am a huge android supporter/early adopter, a car fanatic, and a Mechanical Engineering major. Because I love the individuality of it all and to be able to own something that can be unique to me.

I dont think turning off haptic feedback will really make to much of a difference in terms of battery use.
Our phones are dual core phones, in every test run dual core phones have less of a battery draw because two cpus is better then one. When dealing with a multicore phone/computer the device can have more power without using more energy because there is less stress on the cores. The old way was a bigger battery drainer then this because 1 core would have to use more energy to produce equal amount of power that a 2 core setup would. As spencer said and we have all been saying its more of a software issue then a hardware issue. Imagine loading a computer with 24gbs of memory and have an core i7-Xtream chipset and using windows 7 32bit its pretty much a waste. I believe a lot of the issues that everyone is experiencing will be fixed by a software update or the dev team when roms of the gingerbread nature come out.
Spencer nice post btw!

[Q] Any Decent Battery Savers?

I was wondering if there are any good battery savers for the samsung infuse4G. i have the cpu tuner and not 100% sure how to use it. i have downloaded a half a dozen task manager/killers from the market. as of now i have "advanced task manager" killing every 5 min. i have some apps ignored. on the cpu tuner i messed around with it last night and got all things working fully on it. now it says everything but the power save and performance working. if there is anyone that uses this please let me know exactly how to use it. still a little confused about some settings. and if there is anything else i could try, let me know, and how to use it. Also i am currently on a different rom "bionix 1.2" i have Bluetooth and WiFi and all that normally off. the brightness is lower than 10 % all the time.

First, you posted this in the wrong section. Should be in general.
Second, setting your task manager to auto kill apps will decrease your battery life. On older versions of Android it may have helped, but on Froyo and newer some apps are loaded automatically in the background so they can open quicker when you access them or so they can receive notifications. These apps that are loaded in the background generally aren't doing anything at all and thus aren't using any extra battery. If you set your task manager to automatically kill them they will just keep loading, being killed, loading, being killed, etc., which DOES drain your battery.

This is what I do and may or may not matter but I get great results. Before I flash a ROM, I make sure my battery is charged to 100%. Once you are done flashing the ROM, calibrate the battery by:
- Charge to 100% turned on. Wait for the beep and notification that it is fully charged.
- Unplug and turn the phone off. Once off, plug in and let charge until you see 100% on the screen.
- Unplug again and turn the phone on. Once fully loaded, plug in and charge 100% again.
- Power down into recovery and delete Battery Stats under Advanced menu then reboot.
- Power on and charge to 100% again.
Usually it takes a few days for the battery to settle in but following these instructions, I get instant results.

I just did this. I have the infuse tomm with community voodoo and the battery goes from 100 to 60 in 2 hours with moderate use. I am a heavy tester and the brightness is almost 0 I'm not sure what I am doing wrong

Sorry I was on a phone when I typed that. Meant to say. I have the infuse the rom and I am a heavy texter. Have the brightness on almost 0 and I have CPU tuner going and task manager killing everything except 6 things every 5 min and when the screen is off. I can't figure out why my batter is dying so fast. Like it'll die with moderate use for around 5 hours. even if I have the screen off it'll die. I have some apps frozen with this bloat freezer.

Did you read post #2 here http://forum.xda-developers.com/showpost.php?p=14885241&postcount=2 Auto killing some apps will drain your battery faster than leaving them running. I didn't know this until now. So I have deleted all taskmanager apps I was trying and will only use JD without any task killing functions enabled.

I only use Advanced Task Killer to manually kill tasks. I also am careful not to install tons of stuff at once - that way if I get a "bad app" that eats battery I've got a good guess what the culprit is.
The autobrightness/swipe-brightness trick works great.
Kill WiFi if you're not using it.
The new Infusion undervolt kernel is awesome. One day I was at 50% at the end of a work day (admittedly WiFi was turned on but not in use for a good portion of that), the next day I was at 79% at the end of the day. (WiFi turned off + Infusion kernel set to undervolt with no overclocking.)

Ohh OK. So don't have any task manager; task killers at all? I just figured I would need to have all those apps killed so. I had it backwards. So should I have anything to help the batteRy?

Task killers don't work in froyo and above, because google disabled them.
They're bad. Period.
The one that comes with it is best to use sparingly.

Wrong. Google did nothing to disable them, they just reduced the need for them and the effectiveness of them against many apps.
However, some apps just need a good killing when you're done with them, like Facebook. Facebook seems to inhibit a lot of power management functions from working properly... On my old device (AT&T Tilt2 running XDAndroid), Facebook was the #1 culprit as far as wakelocking a device.
However, as I said - autokillers are BAD, and randomly killing stuff unless you KNOW it's a pesky app can be bad.

use setcpu for profiles, e.g. screen off 100mhz - 200mhz with 100% priority.
running Infused 1.5 with Infusion 1.5 kernel (note that the UV in Infusion 1.5 is broken atm)
screen on auto
wifi/data on 24/7
made couple phone calls
navigation used for ~30 min
online surfing facebook/banking
work e-mail refresh every 5min from 7pm to 10am.
15% after 29hrs use. (is that good?)

No, you are, as evidenced by you linking to an article that is almost a year old without checking to see if anything had changed since it was published. Advanced Task Killer is more than capable of killing apps - Google may have disabled it temporarily last August but it's been working since March of this year at least (That's when I first got a Froyo device). As I stated - some apps (like the Music app) are set up so they auto-respawn when killed, but they CAN be killed (However, autokilling them is going to eat your battery). A number of apps also do NOT auto-respawn, as I said before, Facebook is one example, and it's an example of an app that is notorious for eating battery and needing a task killer to take care of it.
Now the way sleep and power management works on our Infuse might mean Facebook is less problematic on our devices, but in the case of XDAndroid builds on MSM devices, the Facebook app clearly would prevent the device from entering deep sleep in a timely manner, causing it to eat battery like crazy. Killing it with Advanced Task Killer would fix the problem.
Edit: As another example, it can also kill the Browser process successfully, which is great for when the Browser process gets wacked out. I haven't had any issues with the Browser on the Infuse, but it could easily make the whole system extremely sluggish on XDAndroid Froyo builds.

Anyone know the best battery saver that really works good?

Looking for a good battery saver anyone knows one? For inspire 4g

I think Juice Defender works fine and its free. It does its job of killing the mobile data when the screen is off.

Yea I use that already but it seems like my battery still be dying kinda to fast.

Juicedefender +1

+1 juice defender
if you have the money for it, buy juice defender ultimate bc u can customize the settings

honestly, I started out using a task killer and a few other apps, and too didn't see much benefit...
biggest thing that helped me was autostarts...but you'll need to learn how to root your phone...
not only will it help you take control over all the crap that runs in the background, but give you good insight as to how often things start up, for what looks like no really good reason.
between that... I only have 4 home screens and try not to have too many widgets that auto update...
also...no sure about your phone, but my vibrant had the wifi calling app on it, and that thing was a resource hog...~20% battery usage on avg...had to forcefully yank that one from my phone...
good luck

All 'smartphones' barely last a day under heavy use.
There is no magic app that will change that.
Turn off wifi + data and use it only to call or write sms and you will get 2-3 days maybe.

Juice Defender definitively. You'll not find out there better than that. If it's not enough for your usage, you should buy a spare battery and switch between them

Defender or more simple..
Juice Defender best. but sometimes, it can be confuse for newbie. Then you should try Deamon Controller, it is simple. You adjust wake and sleep Mhz of cpu, that's it. Don't forget Wifi, gps, data, bluetooth, sync etc. switch-off.. good luck..

juice defender is definitely the best. some say it kills the battery more than it maintains it. but a good app to use for sure!

No, battery saving apps are a joke.
Install BetterBatteryStats and take a look at your wakelocks. See what's killing your battery. Don't install a battery draining app to help save the battery... makes no sense.
Look into lowering your Wifi TxPower if you enable Wifi alot. Look for guides and tips, there's plenty out there.
I went from 7% loss overnight to about 4% after locating and removing evil apps and installing alternatives.

which battery saving app is good for i9000?

[Q] Battery drain + best antivirus prog?

I am running Infused 1.6.0 and lately i've just been having horrible battery life. I'll let my phone just sit for an hour or 2 and it'll drop 10-20% in battery life.
I have a couple widgets on my phone but only one checks for weather and that is set to check every 2 hours.
I do have Lookout antivirus installed...What does everyone else use as far as antivirus? I have heard alright things about antivirus free but then the reviews say the latest update puts out video ads. I am starting to wonder if Lookout is what is draining my battery.
EDIT: Just got up about 45 minutes ago. All I have done is sent maybe 20 texts that is it and my phones down to 81% :-/

Uninstall Lookout and see if that helps.

Never used lookout but, I know a lot of ppl do. I use bitdefender b/c of the built in find your phone option. As for battery life, download juice defender and a task killer from the market, you can even go so far as download something like SetCPU a set the values low and scale to powersave to save battery.

Actually I have setCPU but haven't really messed with it. I have it set to conservative right now but that doesn't seem to be doing much. I have heard mixed things about task killers...but seems when I kill a task now it just starts back up again. Stuff I don't need to be running either. I will check out juice defender.

I have a task killer but only use it when I'm doing multitasking. SetCPU has plenty of options, just mess with it until you find an optimal combo. Juice Defender does wonders for my battery life.

Battery saver apps

I really need a better battery life for my business phone. My last 3 androids have all had a 20% battery by 3pm....
All of the battery apps claim to turn off network when screen goes blank and so on... however I still have bars of service imidiately after turning screen on. Will I still receive phone calls?

Root your phone, under clock when screen off and manually turn off your interwebz...
Rooted MT3G XM-8 Even Moar Stripped with XDA Premium..

FB is one of the bad culprits. I generally use Autokiller on strict to tweak the Android process things and it works good.

Did you try Juice defender? It's the only one I've tried and works fine so far. My battery last 30% longer after using it, and it wasn't tweaked.

If you don't want the hassle of underclocking, then just go for apps like Green Power and Juice Defender. Set it to turn on every 15 minutes during the day and totally off during the night when you sleep; you'll be surprised how much time you can squeeze out of your battery.

You must use battery saver pro or juice defender and task killer

Okay, task killing apps randomly won't always improve your battery life, for an example, if you kill let's say a play on tv app which is a system app, you might end up wasting more battery as it re-starts.

Juice Defender
I can personally vouche for Juice Defender Ultimate. I love this app, it's always the first I install when I get a new phone. It's saved me at least 3 hours of battery per day. I have the extended battery upgrade on my HTC Rezound, and I used to be at around 30-40% after a day at school (somewhat heavy 4G use, like listening to Grooveshark, browsing the web frequently, etc). Now, with the same, if not more usage, I'm at close to 60% by the end of the day, and it lasts me usually until around 9 at night.
So, Juice Defender=awesomeness. And you're going to want the Ultimate version for extra settings, definitely worth it.

I personally found that Easy Battery Saver which is free on the market gives me the best battery life even better than JuiceDefender which I found hard to believe till I saw the results. My Motorola Atrix has really bad battery life usually only lasts me about 5 hours without the app but with the app it lasts up to 8 or so which is a pretty swell improvement if I say so myself.

I would also say that Juice Defender is a good app... saves quite alot of battery.
but all of the apps using data in the background (facebook etc.) are the battery life drainers

Use juice defender

I use Juice Defender myself. works fine. you can edit what you want on or off. Also memory killer works but you need root

I really need a better battery life for my business phone. My last 3 androids have all had a 20% battery by 3pm....
All of the battery apps claim to turn off network when screen goes blank and so on... however I still have bars of service imidiately after turning screen on. Will I still receive phone calls?

I can second the votes for JuiceDefender - it's done wonders for me.
For the rest of your questions...
Even when an app is toggling your data connection for you it won't affect your cellular connection. You'll still see bars of service (though without a data indicator next to it like "3G" or "H").
You will also still receive phone calls and text messages as (again) your network service remains untouched. Emails or other data services will be delayed until the app enables data.

Try out Bataria. I really notice a difference using it.

That's weird, I got about 1 day of battery life with my Atrix, sometimes 2 when I disable data from time to time.
Which rom do you use ?
Anyway I also use JuiceDefender.

it depends what version of android it has with 2.2 or higher i read that they manage memory pretty well so the task killers might actually take more battery rather than save it. If your Phone 4G you will save alot of battery by turning it to 3g and only turning on 4g when you need the speed

Task killers are never necessary on Android. Apps to manage and toggle data and radios are far more useful - and can be quite beneficial to your battery life.
