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%

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.

What roms have good battery life?

I'm currently running Valhalla final rom and it drains my battery very fast with even minimal use.. I aslways have GPS and wifi off. Always quit all my apps and free the ram when I'm done... any good roms out there with good battery life?
Sent from my SGH-T959V using XDA

I get 2-3 DAYS with valhalla final, so I'm not sure that swapping roms will change your battery life much. You can try one-click gremlin remover before you flash your next rom of choice though.
also, do you have any apps/services that run in the background, like facebook?

+1 to Mike
Alex - there are several recent threads tegarding battery life in the Q&A section. Browse them and see if you can learn a few things how to improve battery life and what the big battery drainers are.
All the ROM's, for the most part, have the potential for great battery life if you use them correctly. WiFi, Sync and GPS need to only be on when you need them. Many apps sync on their own - adjust the sync intervals on them. Use Gemini App Manager or AutoStarts to disable autorun scripts in the apps. Adjust screen brightness. Any data hungry apps (i.e. music streaming, Netflix, etc) will drain your battery regardless what you do. Undervolt with Tegrak Premium. Minimal widgets on home screens.
It is not the ROMs - it is how the end-user uses the ROM and their phone.

Turn off data and background data, until you need it. I get over 2 days sometimes depending on usage

Im running NO widgets, no facebook sync.. the only account that syncs on my phone is gmail... nothing extra downloaded really just mostly valhalla final rom with a few apps.... Im noticing a big difference in battery life from stock gingerbread... I know for a fact that my battery is good because i was always able to use it fully for one day.. i dont charge my phone often to keep battery health in best condition I charge only when its super low.. and once in a while I let it die completely then recharge it fully
I even see a better life on icbinb rom than valhalla.. just wanted to see if anyone else notices the difference guys

You saw Mike says he gets a couple days on Valhalla. Try the Gremlin Remover. Do everything the thread says. It is effective.

Stop doing this. Li-ion batteries are a different breed.
I suggest taking a read over this page.
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
In brief stop treating your li-ion battery like its a ni-cad otherwise you will never have good battery life.

http://forum.xda-developers.com/showpost.php?p=23108980&postcount=33
Last run was for 5 and half days with about 3:30 of display time (internet and such), 1:30 of music streaming and like 20 min of voice calling on stock rooted and debloated KJ6.
Yup, I know, for 5 days that's not much of a usage but point is that SGS4G does not use too much juice when idle.

I keep GPS and Wi-fi on all the time, use the phone pretty hard during the day, and still have 60-70% battery left each evening.
You say that you "quit all my apps and free the ram", so I assume that you are using an app killer. My experience is that they are actually detrimental since they aren't needed and many apps just restart in the background, sucking more battery.

Omg people...your using an android....you want everything at your finger tips and wonder why it eats battery
Try all this while on your laptop without plugging it in.....just get an external charger,and a few extra batteries....all in which are very cheap now.......and then we dont have to listen to all this over and over any more.

I share this app for those who don't know this app and want to test. There is some good feedbacks for other devices. Personnaly I don't use it so don't ask me if battery life is better or worse, test by yourself, share your feedbacks, etc...

That wifi function was what i missed from xperias stamina mode and this has tons more. Hopefully the app keeps at light weight and dont end up drain battery itself.
Looks good! Lets put it to test.

I just installed it. Not expecting much, but we'll see.

We'll see how this works, seems like it could be decent. It says 4 days to calibrate, so be wary of that, crackflashers!

First night deep sleep battery usage dropped from ~60mAh to 24mAh. Seems like a realdeal. :thumbup:

In used this on my DNA and noticed no improvement. I wonder what it'll do with the S800. Going to try again.

I installed it & when it came out of the dormant mode to start saving battery for me, it asked me to keep the location sharing always ON in the LG UI settings, which i had disabled to save battery, i don't understand why does it need location ON?

I don't understand this either. But.... I am at 52% battery with almost 4 hours off screen time and my location services have been on constantly. I believe I read the location services were to determine when it can turn wifi on and off. I'm not 100% on that.

This app didn't do much on my one.
Imo the g2 doesn't need it
Sent from my LG-D801 using Tapatalk 2

I will report back when learning mode is done, sucks that it needs the location services turned on,that alone might defeat its purpose I think.

I used it for a couple of days after 4 days of calibration, i can hardly find any difference. Uninstalled it.

Because it learns places you use wifi and will turn it on and off depending on where you use it.

Guys. The app is designed for people that use their smartphone. Most people leave location services on. Try using your phone with location services OFF and UNINSTAL the app. See how much battery you use. Then use the the app. It causes a HUGE increase in battery. But if you usually leave location off, you won't see much of a difference
Sent from my LG-D800 using Tapatalk

I count about 42% difference on this. My Juicedefender config gives me 96% on average. I'll stick to that.

I've been calibrating for two days and I'm hoping that after calibration has finished, I can just leave my wifi and gps on all the time and it will know when to turn it on and off without my input.

That's exactly how it works I am a flash aholic though:/ so can't use this app

I'm not a flashaholic but I'm seriously looking forward to the day I can flash CM onto my Wind D801!!!! I used CM on my S2 and I really see the value in CM!

At least you'll have the inevitable uninstall to look forward to

It's not looking promising but I'll mess with it a few more days just for giggles.
I seem to be using MORE battery after finishing the learning period. In the morning I check a few news sources then don't touch the phone again until about 10am where I've been, according to the Guru battery indicator 99%. This morning I was at 96%.
Besides changing some autosync settings it didn't apear to do much before and seems the same now.

[Q] Battery saving tips

Hi all,
Although I am more than pleased with the Ascend Mate 7 (silver edition) battery life, I was used to try and save as much battery as I could on my Gnex.
Do any of you use any apps or settings on the Mate to stop it's battery from dropping when the screen is off? I've got Greenify installed as well as Amplify, but although apps are hibernating I still get that popup that app X is using battery in the background. I've also got the usual strange wake locks keeping my device from falling asleep (*backup*, framework services...) , but I'm trying not to get too bothered by them because I know nothing about those sort of things to start messing around.
What do you do to keep the battery life to a maximum?

Battery life is fine for me, I like to have speed so no power saving for me, brightness high (auto), everything allowed data etc.
I just dont worry about battery life, a day of heavy use and I still have a bit left so all is well.

It is the modem that is the biggest battery drainer in this device. best battery tips is use wifi if possible...
This will give you a few more extra battery life.. up to 9 hours screen on time.

Hmmmm. So you say: kill mobile data when you are on wifi?
Do you know of an app that does this automatically, switching between wifi when there is a trusted network and using data when there is not?

This is my observation, people who use minimal amount of 3G or 4G data and wifi instead is those who get 9 hours Screen on time.
People who use no wifi and only 3G/4G and maybe 200-400 MB per day are those who get 4.5 hours of screen on time.
This is nothing unique for this device however this modem is for sure not the most power efficient modem out there..
This is also the reason why people get astronomical differences in battery time.

Do you guys use titanium backup? What apps do you freeze?

I've got it installed but lack the knowledge to use it safely. I am interested to know as well, also which system/stock apps to uninstall safely

Had my mate 7 delivered yesterday. After using it till 2% battery I then charged it up for about 4 hours till fully charged. I took it of charge and went to bed. This morning it says 76% how can it use that much power in standby? It did have a notification about Google play services waking up many times. Any fix? Surely this isn't correct for a phone to do.

Hi @vimto25 I don't really know how to shut down the google play services wake ups. I've tried to use System Tuner to limit the wake locks like in this and this thread, but ultimately I found it made things worse on my Mate 7. Have you installed Better Battery Stats to see what is really keeping your phone awake? Then just search around this forum for a solution or post your wake locks in the better battery stats thread!
Could it bee (this is a laymans opinion) that since this was your first time, your email was busy syncing all your mail?
Hopefully someone else really knows how to help you out! At night I always use the ultrabattery powersave option and never lose more than 10%. And if I do, I usually have a strange wake lock myself, like google play services, *backup* or framework.

I only have 25 emails synced which they synced when I set the phone up earlier that day.
I have looked how frequent it.synced and it said every 15mins which sounds very frequent but all my devices I've had emails syncing around 10 mins.
But I'm guessing it's email that's my problem hence why it said 40% with over 1 hour cpu time. Hmmm I've changed the sync time but I can't see that helping much.
I think I'll do what you have done by enabling power saving mode at night. I currently use normal all the time.
I LOVE this phone just need this small problem sorting.

It would be nice if someone can list some information on how he has set up his phone for battery performance.
Anyway i always use ''smart mode'' of the battery,
i have 5 email accounts in push , always pushing , but my battery on 8 hours a day of screen on and messenger chatting, on mobile data or wifi always on its battery lasts like 1day and 3/4 on !
you can enter the phone manager app and disable the user apps from booting up. just live the ones you need, like whatsap, messenger, google service, gmail, super user or smth else.
Hope it helps !
cheeers !

I'm going to see how it is again tonight. I may restart the phone before bed and see what happens. So far battery isn't very good for me but I can see it has potential so it's how the device is set up the end of the day. Just didn't expect my battery to drain that much and esp using email on standby.

Do not set it manual, just set your E mail in push mode. Not by interval.
