Battery calibration HELP

So I love the phone but I just can't stand this battery anymore I'm starting to think t mobile gave me a used battery. Ive tried draining the battery to 0 then charging it to 100 nothing. I tried the restart nothing. I work from 8 to 4 and I start the day with 100 and end with 10 if I'm lucky! As I'm typing this its at 87% and its only 9:04. Running services like app pack car home and such are off wifi is off brightness at 50 and I kill tasks a lot with ATK can someone please give me a step by step on how to calibrate even if I have to mod the phone Thank you =)

I'm having the same issue as well. I just received my phone yesterday and I charged it fully last night and kept it unplugged over night. Overnight it only lost about 3%. But after medium ussage this morning which consisted of checking email/texting/surfing the web, the battery dropped a significant 25% over the course of 40 minutes. Any suggestions?

Root phone if you havent already
Charge phone to 100%
Flash clockworkrecovery
Boot into recovery and under the advanced menu select "Wipe Battery Stats"
Reboot

That kind of behavior is normal. The phone loses very little while idle but checking email and web surfing both require a data connection and that uses a lot of power. More usage = faster battery drain.

My galaxy s would easily last a full day with constant email/text and a couple hours of talk. This phone doesn't even seem to be able to last me a few hours. Do you also experience this significant battery loss?

You prolly need to do a factory reset. For some reason some peoples phones use more power even at idle than they should. My phone was one of them. There is a whole thread about it but pretty much doing a factory reset should correct this issue. Did for me. I get almost twice the battery life of my Galaxy S.

No need to go into recovery to wipe the stats, just use Battery Calibration(requires root) its in the market and also includes instructions on how to use the app.

true story. ive never used it so it didnt come to mind lol.

In the passed hour I've now lost 40%. That can't be right, can it? :/ I'm running everything stock btw and I'm unfamiliar with rooting and things of that nature.

I had the same problem. I followed the thread below and it worked. I've ben getting 10-15 on moderate-heavy use. I also did the htc battery calibration before I ran the battery calibration app. I use juice defender as well.

Check out the link jsauce75 posted. If you are running stock that means you most likely have background services running that are pulling significant battery. You will need to root and then use titanium backup to either remove or freeze those services.
Before doing that thought I would download Battery Monitor Widget. Use it to see how much power (mA) your phone is using. When I first got mine I was draining battery fast and when I used that widget I learned that the phone was using over 100mA even when idle. It was like the phone would never go into a sleep state. After doing a factory reset my phone idles at 1-2mA.
There isnt much you can do about battery drain while you use the phone because the screen and data connection are huge battery drains. All these tips are to improve your power consumption while idling. As I said before all I have done is factory reset and removed unneeded services and I have been getting double the battery life of my Galaxy S with the exact same apps and usage for weeks now.

1) You said you're using ATK "a lot". This is adding fuel to the fire. ATK is not needed with today's android systems. These apps you see sitting in ATK are sitting dormant. It's like the task manager of a computer. I have 3-4 apps running in my system tray and around 20 other services running in my task manager.. They are all sitting dormant, using zero CPU. They have ram allocated to them. That's it. That's the same as the Android. They are sitting dormant, and they have memory allocated to them. The best thing about the android OS is that it will automatically shut down dormant apps on its own. A PC doesn't do that. So, look at it this way. Let's say I'm on my laptop's battery. I have 20 apps/services running, and they are dormant. They are doing nothing towards drainage of my battery. But, I decide to turn on my screen "a lot" during the day, and kill the apps. Boom... Battery usage for the CPU to turn the screen on, the screen takes away from the battery, usage for the task monitor to be running.. Then, there is a process to shut down the apps, that takes battery.. Then on top of all that.. When the apps restart on their own.. guess what, they have CPU/Battery usage. You're adding fuel to the fire.... a lot of it, imho.
2) Install Watchdog and Titanium Backup (pay the small fee so you can freeze the apps.. or you can learn how to manually remove them yourself. I like using the app). Now, just to prove the point.. Open up ATK... Then go into Watchdog.. You'll see the apps that are running in ATK are not using any CPU. But.. when they do start up/shut down, there is some usage going on that will contribute. So with Titanium backup, freeze the apps. The apps I have frozen: AppPack, Broswer (have dolphin installed instead), Car home (2 of them?), com.android.provider. applications, com.logmein.resecuesecurity and .rescue, email (using gmail instead), My account (2 of them?), nfs shift, nova, street view, tmo TV, tegrazone, telenav, videochat voice dialer, zinio reader, zsprovider. From there, you can see the apps running in watchdog and you don't need ATK.. But, watchdog also uses processor to "monitor" the usage of other apps.. So place the threshold setting at like 40%, and the frequency at 3 or 5min. This will keep Watchdog from using too much battery, but it'll also notify you if an app is running wild on cpu usage. Maybe for 1 day, put the threshold at 30% or maybe even 20%.. so you can see if 1 or 2 apps are using a lot of power. If they are system apps or apps you want.. just leave em be. If they are not, freeze them/uninstall them.
3) I have found that using wifi and wifi calling GREATLY increases my battery life. As soon as I turn on 2g/3g/4g... my battery starts to take a fast dive. Whenever possible, use wifi/wifi calling...
4) Screen down to the lowest brightness setting. Shut off screen manually whneever you are done, or set it to 15sec shut off. I only bump up the brightness when i'm outdoors.. The glare makes the low setting impossible to see the screen.
5) Shut off syncing, bluetooth, and gps unless you need it. If you're around a computer at all where you can get your email and such, there is no need to use the phone for it. I only use tmo's network and syncing when I'm away from work or the house... typically when I'm on the road.
Lastly, yes, some people want to use their phone... use the 4g service.. etc. I understand.. But also understand that if you're going to use the phone like a computer.. and you're going to get 8hrs out of the battery... I say that's pretty dam good. This post is not meant to say that there is nothing wrong w/ the battery... It's to help you out to determine if there is a problem in the first place. There was a guy complaining about battery usage left and right. When I got involved in disussions with him, he admitted that he's on his phone all day long... txting quite a bit. Well.. duh?
I don't doubt there could be some challenges with a bad app running wild, a bad battery, etc. But I also don't doubt there are people who are using the crap out of a dual core phone.. and are doing things themselves to add to the problem... and then they blame the phone.
That's my 2c....

Thanks for the great detailed response. The OP actually was the one who stated he uses ATK, I don't. I looked through the thread with the recommendations for 20+ hour battery life and noticed that those apps you mentioned above required rooting the phone. I hate to sound so naive when it comes to this stuff but i'm a fairly new android user and have not yet discovered a lot of the technical aspects behind it all. I'm not exactly sure what rooting is and what it entails. Is it something you suggest I do? Also, my battery is slowly approaching 0%. Should I let it drain all the way before charging it again? Others suggested letting it drain all the way and doing a factory reset and that seemed to help their issues.

By default Android restricts certain areas of the OS from being accessed by third-party applications (prolly for security reasons). Only problem is a lot of great apps require such access to function properly. In order to give them that access you must root the phone.
Here is the rooting thread. It is extremely easy to do.

Does rooting affect warranty in any way?
or the ability to perform a factory reset for that matter?

New to android is not an excuse, I was a religious crackberry user for the last 8 years, and I just switched over to android last month. I'd suggest you to root you phone so that you can remove the stock cr4pwares, and the ability to install custom ROMs. Took me 10 mins to figured out how to install andriod OS into my hd2, 25 mins to perm rooted and unlocked my g2(this beast is little bit more "lockdown" than the other), and 5 mins to rooted the g2x. Google is your friend, bud. If you want something more out of your g2x, use the "search" button. Just my 2 cents.

FYI: I'm a first time android user (smartphone user at that..) and I rooted my phone easily. You can unroot your phone just as easy as you rooted it. It's a 1 click method with that software.. check out the link. Seriously, it's easy.
You may have to have ABD ADB or whatever installed first.. Not sure. I heard about it, and did it... and then rooted.. and it worked.

Thanks for the help guys, appreciate it. I'll let you know how it goes
I'm also having another issue with the phone. I'll see if you guys can help without having to make a new thread.
Yesterday I installed Zedge and downloaded one of the wallpapers there. When I applied the wallpaper I noticed a bit of lag on my home screens, so I reverted back to the default wallpaper and the lag was still there. I deleted the app and wallpaper I downloaded but the lag was still there. I applied a default live wallpaper and the lag disappeared and everything was moving as smoothly as it had been originally, but when I apply the regular wallpaper the lag persists. Any ideas?

now if u do root and remove bloatware what all is safe to remove i have all but my account car home and i think one other can anyone provide a definite list and battery is significantly better after just that

LOL think there's not driver issues. Swapped a dead battery with a fully charges one today and been running almost 2 hours still shows 1%

Battery saving tips

Thought this might help. Please share your tips.
1. Underclock and undervolt your cpu. 1.5 is not needed for every day use. Use system tuner free from market.
2. Set screen off profile lower in system tuner settings.
3. Use juice defender to manage connections whilst screen off. Free from the market.
4. Use watchdog to keep an eye on any mis-behaving apps using too much power. Free from the market
5. Turn off auto brightness. Manage it your self. Most of the time indoors you can have it on lowest setting.
6. Don't charge your battery all the time let it run down to like 30% then recharge.
7. Don't use auto task killers
I've tried most roms and kernals.
My best combo for battery use is
InsertCoin latest with bricked 1.4 and cam fix.
I underclock @ 1.15 and undervolt @-100mV
Battery stats are difficult to report accurately but I use 1% whilst in standby for 2-3 hours

Jeez It's only 3 apps and they run pretty minimally ....... The other 100+ I have installed don't affect my battery either, juice saves about an extra 30% and watchdog let's me know if any apps are Misbehaving. Underclock and undervolt save me loads of battery, don't fancy doing it via script
Could make it 4
Autostarts is a good one it prevents apps from starting unnecessarily

Ah, thanks - that's actually a good explanation.
I will remove the android task killer, but how do you deal with crashed apps... e.g. maps? You can't kill them with the taskmanager, can you?

I have advanced task killer installed with autokill turned off so that I can kill apps as and when I need, apps rarely crash tho....

Well, I don't know if it was just the version of the latest map app, but in fact it crashed on my phone once or twice a day while using the cache-only mode. Anyway, I think we are getting off topic here.

in premium version you have the night mode and can shut off wifi and 2/3/4g.

also i set it up to turn on mobilde data only every 15 minutes for 1 minute to sync data.
works great for me

As far as I am familiar with Li-Ion batteries, that would accomplish nothing... Li-Ion batteries are full at 4.2mV, end of story... Everything you do after that is just voodoo
All you can do is calibrate your system to make the most use of your battery... But Li-Ion batteries are pretty much self-controlled, and self-preserved... They like being charged often, they don't like being too low, they don't like being too full, they like the working atmosphere of the middle range...
Also, they don't mind working while they're being charged

4200mV or 4.2V but yes that is accurate. Allowing the battery to go through full cycles when installing new ROMs helps your batterystats.bin though.

Sorry if this has been asked
I just got my g2x and the battery isn't that good like the mytouch 4g
So can someone suggest a good app to download. I currently only have app killer

It really isnt good to use task killers on phones because it can screw with the Roms and such, but a good app to use would be something like Juice Defender. Hope this helped!

So get rid of task killer and download juice defender. Is there a specific set up I should use. I don't want it to interfere with me getting calls or text messages

It comes with several presets. I use balanced, doesn't effect radio(I don't think any of them do), but one kool thing it does is stop data when your screen is off. That alone gave me a extra 3 to 4 hours, easy. It has a lot of kool other features to help. Advanced task killer- no noticeable difference. Juice defender- anywhere from 3 to 5 hours.
Sent from my LG-P999 using XDA App

Unless you buy the premium version of Juice Defender there is no way to configure for individual apps. I though data off when the screen goes off would be great, but if you need your POP Email in a timely manner it does not work so well.
I have not used it in a while, so someone correct me if I am wrong.
I am going to try Autostarts from the Android market tonight and see if stopping all the runaway apps helps.

If you have the free version of JD (I do) you can set up your schedule so that JD automagically enables data every few minutes to sync background data. I have it set up as 30 minutes.
Click the "custom" setup in JD. You can also buy the premium version which will give you much more control in the settings dept.
OP,
Used to come from MT4G?? I'm getting WAYYYYYY better battery life compared to my previous MT4G, but maybe that's just me. (I also like the G2x WAYYYY better)

I am also coming from a Mytouch 4G and so far only tried out 1 MIUI rom and still new but got 8 and a half hours of really heavy use with 10% when I got home which I think is pretty good I like this phone much better and notice it's way more faster and less laggy only thing is personally it's not as sexy looking as my white Mytouch 4G was I actually think the design of this phone is kind of weird hoping it looks a little better with a nice case.

For Juice Defender, YMMV. I tried it and my battery life was worse compared to without it.
I admit to using Andro Task Killer. Unlike other task killers it doesn't kill system tasks. I tested it and it improves my battery life by 15%.
Also, install a good firewall like DroidWall and ruthlessly deny internet access to any application that does not depend upon it. This will save you lots of battery life.
Get SetCPU and set a profile to tune your CPU frequency to the minimum when your screen is off.

I use watchdog. When a rogue app gets over 30% cpu running in the background I close it. Helped me more than juice defender.
Sent from my LG-P999 using XDA App

Little bit of advice... App killers are not that great because they will kill all apps and then all those apps will start again draining more battery than they would just quietly running in the background
I also recommend watchdog to kill apps one by one if u want and monitor rogue alps

Actually they do, take a stock rom, unrooted and use a task killer to kill the ton of garbage running then wait a couple of minutes and check back again, there will be at least a few of those killed apps running again, if not more, not to mention any background services that are supposed to be running that likely didn't get killed.
If excess apps running are draining battery life either uninstall some, or if they are stock apps then root+freeze, no more irritating apps running in the background to drain battery life.
Edit: Also, apps like ATK run in the background as well, draining battery life as well, on top of the apps trying to run. Similar with Juice Defender, it's always running, I noticed improvement not only in system performance but battery life after I uninstalled Juice Defender.
The only "batery saver" app that does anything is the one from AnTutu, but it underclocks your CPU and who knows what else, so even that is a double edge sword.

Look, why don't you run your own tests with Andro Task Killer? What you wrote is not completely accurate, and does not change the fact that I get 15% more battery life with my task killer, Period.
That is because some apps spawn background tasks that stay running after you close the app. These background tasks are made difficult to identify without using an advanced task manager like Elixir. They might use your data connection to send background data, or a poorly written app can keep your phone awake. Both ruins battery life.

I use jd ultimate being able to have your antennas off saves batteries period. Not to mention the hundreds of features to tweak it i get substantial battery savings with jd. I am unfortunatly against task killers... i use antek to just freeze the annoying apps instead of killing them over and over and keeping another uneccesary app running...
Making bad decision's one at a time.

Oh p.s. owning a g2x=bad battery life period.

I am unfortunatly against task killers... i use antek to just freeze the annoying apps instead of killing them over and over and keeping another uneccesary app running...
Making bad decision's one at a time.

JD ultimate really helps in addition to setcpu and some undervolting.

If you have the free version of JD (I do) you can set up your schedule so that JD automagically enables data every few minutes to sync background data. I have it set up as 30 minutes.
Click the "custom" setup in JD. You can also buy the premium version which will give you much more control in the settings dept.
OP,
Used to come from MT4G?? I'm getting WAYYYYYY better battery life compared to my previous MT4G, but maybe that's just me. (I also like the G2x WAYYYY better)

Do you use POP email? My email is set for 30 minutes. JD was set at 30 and then 15. I missed emails for hours. Love to squeak an extra hour or 2 out of the battery. I am using stock email on 2.3.
Thanks

[Q] How to increase battery life?

hey im a noob here so im sorry if this has been asked before but right now i upgraded my phone to ics and the battery life is horrible and im too cheap to get a battery extender so is there anything i can do to improve it or am i just going to have to deal with it?

Get your phone to 100% battery and then just play whatever you like until it completely dies. Then, plug it in to charge and dont touch it until it gets back up to 100%. That is supposed to increase the battery lasting time by 20%. It only works once...so dont do it 5 times hoping for results. This is supposed to be done when you first get the phone, but if its never been you've never done it, its worth the shot.

Let the ROM 'soak' in. It'll get better. You are probably busy messing with it figuring out all the features which is normal and makes the battery seem terrible. But overall it is pretty good.
And the post above is an old wives tale these days. It's funny to read people still recommending it.

Kinda, when you first flash with a factory reset, you don't have a battery stats file. This is another good reason to flash when your battery is 100% charged. When Senior Members here say "soak in", they are saying that the first boot all of the system apk (application packages) are cached to /cache. Doing too much while these apps are being cached screws up the statistics of the battery stats. If I really want good battery life, I totally wipe, and let the phone sit for 10-15 minutes. I leave usb plugged in till it's 100%, then pull the usb and use the phone until it totally dies.
By this time, the day is over and it needs to be charged anyways. I plug it into the charger before bed and let it charge up all the way with nothing running (no wifi, no bt, no background apps running).
After that charge, battery life seems soo much better. ymmv. it would be good to know if that works for you too.
Otherwise, everyone uses their phone differently, and some people install stupid apps that have intensive background services running that eat batteries, then complain about the rom sucking instead of introspecting about how they use their phone.

Just to clarify - battery stats file have nothing to do with battery performance and the battery stat file "is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point)." Google Engineer Dianne Hackborn

ahh ok thanks guys ill do what you guys said and see if it helps

you can also install one of the battery saver apps on the market, like juice defender or similar. They will typically help and some can control how often background services are allowed to collect data.

These arent as helpful as they use to be. I have seen and challenged people to run with and without and the added battery life is either very minimal or actually worse with these apps.
Battery saver apps where created when android was very young and had bad management of the battery power. The way it works now it should lower the power to the radios low enough to save battery but not completely shut off the radios. Shutting them off will actually harm battery life because it takes so much more power to turn them on and off repeatedly then to let them idle.

no i think it was more designed for froyo and gb because if you try those battery savers in froyo or gb you can see it works and battery last long but if you test it in ics or jb (i have test juice defender with jb in the sgs3) and what i can see its that sometimes it lags (not always just when you like two or three apps open which for me in the sgs3 was weird) and data sometimes hangs i mean it doesn't load pages

Download Gemini from the play store and manage the autorun for apps. That's what I do and it saves quite a bit of battery

Ill agree with you on froyo but gingerbread towards the end was much better.
The biggest thing is people dont realize how much power is used to start and stop things. Letting them idle will use battery but not nearly as much if you start and stop many times a day. Now at night if you want to turn off those things then yeah go for it. But if you are a frequent phone checker then starting and stopping them everytime will chew through the battery.
A good example is this, its summertime go outside and look at your electric meter when the ac first turns on. It will spin reeal fast for a minute or so while the system gets everything going then it will slow down. This same thing applies to your phone and its radios. Each time you shut it off it has to go through a process so you dont get corrupted data. And when you turn it on it has to use a lot of battery to make sure things dont get messed up and get to the proper operating form.
So any app that shuts off the radios manually and such will end up costing you battery if you are a power user.

If you can follow the steps exactly as i wrote them, then install the team FAH-Q kernel found in the dev section...

I put FAH-Q kernal on AOKP and it seemed to help a bit. I was using systempanel and it said facebook was sucking cpu at night while the phone was resting... so i took off facebook for the moment to see if any other apps/processes could be causing a drain.
side note:
I spend 15-20 min in the morning going through stuff on my phone. Then I will listen to music in the car on my way to work 35 min. My phone will be at 80% by the time i walk in to work. I check things during the work day once and a while and by 2pm I will be around 40%. leaving work I will have 35-30% .... ok i'll just quit now and say running 12hrs i will have about 15% left. I think I am an average phone user. not sure how much everyone else uses theirs.

Music soaks up a lot of battery as well as display, data, and sync. You can try turning off sync and data when you don't need them. But it sounds like you are doing better. I am still concerned with what else you have running in the background though... however, 12-16 hours isn't bad at all...

What do you mean by totally wipe? do you mean go into recovery to wipe data, cache, and davlik cache? then restore after the battery is fully charged?

Yes, as well as /system/ and at least .android_secure on your microSD
I would recommend against fully discharging your battery as a matter of course. While this might have been useful in the days of NiCads, deep discharges and heat are the Kryptonite of LiIon batteries.

Let's start off with calibrating battery tips. What do you think you need to do to properly calibrate a battery?
Here is what I think is required:
1. Charge phone to 100%
2. Discharge to 0%
3. Let phone sit for 5 minutes
4. Plug it in without turning the phone on
5. Charge without break to 100%
6. Repeat 2-3 times

No problem. Please post advice about batteries if you have any.

For non rooted phones, users should lower the screen brightness, screen uses the biggest amount of battery.
Gps, haptic feedback, data should be turned off when not in use.
Also users can install auto task killers that auto kill processes/apps thus saving the battery.
With android assistant +18 app you can also do that and also disable the start up of certain apps, so they aren't on since you turn on the phone.
For rooted phones, Greenify app can lower the battery battery usage by fiddling with app processes.
Ill edit if I rememember anything else.

Thank you for the advice. No offence, but I heard task killers are bad. I heard that Android kills task in a more effective way if it needs more memory. I also heard that killing tasks require battery to do so. Is this true?

Task killers are great if you have a lot of running apps, they work good for me, set them to kill every 30 mins and you dont have to worry if you left an app running in background.
When the battery life is in question, the little things also matter

Your right task killers are pointless on Android. When you kill something android normally just restarts it (depending on what it is) It also takes more to restart it then it does to leave it be.

Take a look at Greenify app. It hibernates your apps on the fly. Meaning they're frozen until you need them. It prevents power drainage done by Facebook or Maps, and others badly written, yet useful from time to time apps.
It really does make a difference on your battery life.
On the other hand task killers are useless since Jelly Beans, as it handles memory management in other way. Low Memory Killer values are dynamic, changed by OS according to your usage odd the phone. Killing apps does nothing else but force them be run again according to their schedule, which results in bigger battery drain and to top it all task killer needs power as well.
Just my 2 cents from a noob.

I dis try the app for while. But as I don't use alot of apps like maps. (Got a GPS for that) Facebook I only use from time to time and have no issues with it effecting battery life. I normally get around 36 hours on a single charge.

It does sound like a good battery life, but I bet if would look at your wakelocks you'll find Facebook among top of them. Even if you use it just from time to time it wakes your phone to often in my opinion.

Here is charging tips. Please correct me if I am wrong.
NORMAL USE
1. Charge when >50%
2. Charge until 100%
HEALTHY CHARGE (Every month or so)
1. Discharge to >20%
2. Charge until 100%
Make sure to take your case off, it will generate extra heat that is bad for your battery.

Thank you for contributing everyone.

Follow the method of full charge and full discharge. Don’t put your phone on charging when there is the battery remaining it for another few hours unless it’s very important. Charge it when your battery is about to get totally discharged and when you put it for charging, let it get charged totally.

Is it not bad to allow your battery to run down to 0%?

Its actually healthy if you get it to full charge after that, laptop batteries are also kept healthy with that method.
