Hi.
I recently purchased a new battery since the old one is kind of broken.
However it didn't really increase battery life at all. In fact it now shuts down at 35%.
How do I make sure it actually makes use of the whole new battery?

Yes it is.
You must calibrate the battery.
To do it you must be rooted.
Advanced method;
Use a root explorer and go to /data/system. Delete "batterystats.bin" file . Then drain all the battery and charge it while phone is off and unplug the cable whem it says full.. Thats all.
Also there is much easier way to do it if you want. Download battery calibrater app from google play and use it! BUT in any of these methods,you must be rooted.
After doing this it must be normal.Also flashing stock rom and non rooted musn't be problem

This is not true.
http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
This misconception must stop being spread.
Though you're right about the charging bit, op should discharge until it's completely dead, then fully charge it and let it run out, repeat the process.

adytum is right. The phone doesn't need to be rooted. Rooted you can destroy the phones battery statistic file at once but you don't need to. Android permanently learns about your battery (high / low voltage) when charging and discharging.
Have some patience, give your new battery some full charges / discharges and everything should be OK.
I'm going to start working on this then.
Thanks alot !
I was already afraid my whole SGS was broken.
edit: But doesn't draining the battery completely lower its lifetime?

Difficult question - doing big researches will lead to different answers.
The only thing for sure is that completely drained or somehow even completely full batteries will age faster because of electrochemical reactions. Completely drained is worst case, of course.
A common recommendation of the industrie is to store an unused battery charged at about 60-70% and then put it away in some cold storage. That is because even LiIo-batteries suffer self-discharge of about 5-10% per month so it could avoid both stressfull states (0% / 100%) for a long time.
Your phone will never physically drain the battery completely, but will shut down itself before damage is done (don't know if this limit/border could be tweaked, but with StockROMs you should be save). Although it might say 0% there is still some energy left. So it wouldn't hurt to "drain your battery completely" down to 0% a few time if you don't forget to charge it afterwards.
As Android stores the min and max voltage of your battery your really should do complete cycles if you want Android to get your battery statistics right. You even have to do this if you killed Androids battery file on a rooted phone.
Much more damage will be done by keeping the battery at high temperatures, e.g. playing heavy games
I've been doing what has been suggested, however my phone keeps turning off between 30-40%.
Is there any way to solve this?

If you already have a rooted phone and no patience (no experience myself on this matter with ICS or JB), then you could use app "BatteryCalibration" to remove batterystats.bin file as was said in one of the initial postings.
if u use cm10 you can also enter cwm and whipe battery stats, i think under advanced

Hi there; this is my first post so please go easy on me.
Bought a Nexus 4 which is my first Android device, but the battery life is bugging the hell out of me. Surely the screen should always be at the top, right? I left it to sleep overnight on a full charge to find that it had shot down to 60% when I woke up at 7 this morning.
I haven't rooted or flashed or anything like that, because as I said, I'm an Android virgin. I have location settings off, only Gmail syncing and the usual push notifications here and there. Nothing too fancy or strenuous.
Any help on how I can go around fixing this? I'm a little afraid to rooting/flashing/ROMs etc, because I've no clue what works best.
Cheers!
If your saying you left the screen on over night, meaning the phone never went into deep sleep.. If you slept for let's say 6 hours and the phones screen was on for that whole time it's normal that it went down to sixty percent battery.
Maybe I'm understanding your post wrong? Btw I cannot see the picture you posted.

Turn off mobile data and lower the screen brightness to 0 during the day. Also disable WiFi when you're sleeping. I also make sure all apps are closed using the app manager button on the far right.
Mine's been fine following this logic.
Oh sorry, I should meant sleeping overnight, whilst I slept cosily in my bed.

This is NOT the answer. His battery in the image has dropped 7%. If he hasn't used the screen much it is perfectly understandable that screen might not be a large percentage of that 7%. As he uses the phone more screen will use a larger percentage of his battery and Android OS will use less.
If he gets to the point where the screen is on for an hour or two and the percentages are still like this then yes there is a problem.

Actually No the "Screen" should not always be at the top of the stat list. If you use the phone more than it idles, then yes... but if you are like me, mine says "Phone Idle: 20%" (which is on top) and "Screen" is 4th on the list with 12% (Wi-Fi and Cell standby above it) [this is my personal phone, and I mostly use my work phone. hence the high Idle & standby]
I was having an issue with my phone running out of battery, with very little usage from it. I mean very little, I might make 2 calls from it each day, and respond to an email now and then. I found that an App was preventing my Screen from going into "Deep Sleep" or even "Sleeping" possibly. So I uninstalled all apps (well I only had like 4 additional apps installed), except for 2 that I need (Google Voice & Drive). Powered off the phone, charged it fully, then powered back on. Its been running on the same charge for 24+hrs now and reads 68% battery remaining.
So check the apps you have installed, some use background data, and might be causing problems...

And your phone is the definitive guide for what Android OS usage is? Maybe his phone woke up those services for a period of time longer than normal.
The answer of "lol looks wrong root and install kernel" is terrible advice when so little information is given.

A longer battery graph would help a lot. If yuppy want top search XDA there is a free app called better battery stats that will help you diagnose if something is running in the background eating battery or even if your phone I'd properly entering deep sleep.

See now it is much easier to see that you actually do have a problem and what it is. You have the wakelock problem as you can see from Better Battery Stats which falls under Android OS on the other screen. It also appears that you have somewhat weak signal which could cause the wakelock to drain battery even more. There's not much you can do about that wake lock, some kernels have patches for it but those have their own issues as well.

Could I just install any kernel on stock android and be OK with it? As I've said I've no idea what's best for me; just something nice and clean that doesn't have issues like this. I live onsite where I work so my WiFi is pretty much on all the time if that helps in anyway whatsoever
I'm gonna let it run down completely tonight and charge it, but I don't expect it to help much.

I never told him to install a kernel. The advice I gave is to do a reset then I asked if he was rooted or running a custom rom or kernel because that might of been the problem.

Fully charged overnight, battery still sinking like a ship. 45 minutes and I'm already down to 94% already!
Idiot question; will installing a kernel just solve this? For now as a new guy I'd like to keep it as stock as possible before fiddling with it.

The battery on the n4 seems horrible.
I'm completely stock I just got my phone yesterday, I charged it to 100% now its at 64% battery with only 47 minutes of screen on time.
on the s3 I would be around 83% with 47 minutes of screen on time.
I'm gonna unlock the boot loader and root soon and try Franco kernel I've been reading good things about it.
Sent from my Nexus 4 using xda app-developers app
The battery life on the stock kernel isn't great because the CPU management isn't optimized well. It ramps up the CPU (frequency, number of active cores...) very easily and keeps it there long, which removes the occasional lag but sucks more battery. Flashing a more battery friendly kernel would definitely help you if that is the root of your battery issues and not a badly coded app.
Franco's kernel is a very popular one, and very battery friendly compared to stock (and that doesn't mean you lose performance). It is the one I'm currently using. Most people report of screen on times of 4 or 5 hours. With not so heavy usage and wifi (not 3g) I can also pass 5 hrs.
To install a kernel you need to unlock your boot loader and install a custom recovery. No need to root, but.. why not since you're at it
You can try different kernels with the stock ROM. You don't necessarily need a custom ROM. Just be careful to read the dev's OP and instructions, and definitely not to flash a kernel for another device.
Also another thing that reduces battery is your mobile data, if there are a lot of programs that sync on the background. You can use a program that turns off your mobile data when your screen is off and switch it back on just for a sync every xx minutes. Juice Defender is such app, though I like to use Tasker for that. If you use Tasker and are interested in that project, ask or send me a pm. It works great.
I used to have 4-5h screen time but recently i noticed that i can barely reach 3. I havent change anything. Ang sugesstions? Thanks in advance.

Try using this app:
http://forum.xda-developers.com/showthread.php?t=1179809
It's very detailed.
Check if your phone goes into deep sleep.
I agree with above poster and if you been around xda enough you know there is a laundry list of stuff to try and no one can tell you why your battery life got worst. But there are apps that can help you and worst comes to worst just factory reset and start over.
Wherever I charge my Note 3 fully, even if I leave it on for extra 30 mins, unplug charger and reboot the phone, phone comes on to 98%. Even when I charge full and just unplug, it drains to 98% on idle in 20 to 30 mins. Whenever it gets to 98% then it stops draining. I believe I need to recalibrate?
I have tried everything I can but to no avail! Every good re calibration app with super reviews! Still nothing! Even Manual recalibration and FULL WIPE (Including Internal SD), tried total drain to 0% and switched off itself too.
Need suggestions. Cheers!
the battery will charge to 100% then turn off and allow the device to go down to about 95% before recharging back up. It stops you from overcharging your battery and destroying it, there is no drama with your battery from what you describe mine does exactly the same thing on both devices I have had

I understand u very well, but it just seems off! Because going down to 98% without even 'touching' the phone, NO WAKELOCKS, nothing serious enough at least... And it wasn't always this way. Just started about a month ago or so. My S2, S3, and S4 never did like so... But thanks for your time bro!

Thank you bhai! But, do you think it's MJ7 firmware? Battery is not as good as MI2, and earlier. And can you we flash MJ6 over MJ7? Since both have the new bootloader, it should work fine yes?
Mine does the same! 98% limit.
I get 10hrs usage before recharging again. :good:
Stop being so anal - . Battery will drop slightly, mine does it, as do many others in this thread. 100% to 98% is nothing. It's usually after 90% that you start to see the real battery life anyway.

Do you understand words have more than one meaning? - In this instance you "seem" to think that the term anal is used in a sexual context. Whether it's a miscomunication in language/Lost in translation or you are just too stupid/naive to realise.. I do not know. - So think before you start crying in a thread next time. A word you may say in your country may offend many here also -
-- As for the battery percentage question, I gave an answer for that, so stop being anal about it.
What you said is same as saying dont be an a**hole!! And second dont refer other people as being stupid/native just because you know 1 or 2 things!
About the battery % it isnt a problem. Its normal system fuction it happens to everyone including me. And I get 10hrs of use with single charge.

Calling someone anal does not constitute the same as saying someone as you put it "an a**hole!!" - I never called you stupid or "native" (Naive is what I said) I merely stated I didn't know if you were either of these you implied otherwise... I never claimed to know anything, So your point is moot. (Google it if you're stuck)

-- Again with the battery situation, it's perfectly normal, It seems this subject has been hijacked by someone who has obviously got lost in translation and has disctracted the thread.
Stay away from Battery calibration Apps, they can play havoc with your phone also, at first they work but they always have a tendancy to mess up at some point.
Unless your battery is draining at a crazy speed I wouldn't worry too much. - You should be getting about 15-20 hours with an average of 3-4hrs screen time out of the devce with moderate use.
Sorry i mean stupid/naive not native.
Mate, there is no need for all these...
If im boring dont reply.
Next time try to explain without putting anyword to show or trying to make people feel stupid. This is my point.
We arent in english gLass and the thread is worldwide, just get to the point and move on.
Just that.
My battery is okay...I get 10hr of heavy use. 3g and bluetooth always on. My s3 had only 6hrs of heavy usage.
I dont complain of battery draining is normal for my usage.

So moving on, you get a solid 10 hours with heavy use currently? - how is your consumption at night? - mine drops about 5% over a period of about 7-8 hrs roughly.

My Note 3 also drops from 100% to 98% very quickly even with no use of the phone.It also seems to drop to the low 90% range very quickly but then it settles down and battery life is excellent.Surfing the web seems to use more power than watching videos.I lose about 3 to 4% overnight.
I noticed my battery discharge faster after upgrading to latest MJ7 firmware. Before the update, my battery lasted very long. Hopefully samsung release a small update fix on this battery bug.

My nexus 4 heats up very much when using 3G data or while charging. It also drains battery very quickly while using 3g data or even when the phone is idle. Here's how I fixed it. [ YOU MUST BE ROOTED IN ORDER TO DO THIS]
WORKS ONLY WITH ANDROID 4.4.2
1.You need to flash franco.kernel for nexus 4.
2. Calibrate your battery. There are tons of apps to do this which are available on google play store.
3. Enjoy your Nexus 4.
Thank me if it helped or Thank me even if this not helped. Thank me if you read it xD
1. Why? There are many great kernels avaible for the Nexus 4 , why does it have to be franco?
2.You should read some more about how batteries in modern smartphones work , its just a placebo effect , "calibrating" doesent help at all , and actually running your battery low on purpose can hurt it.
3.The nexus 4 has a fairly small battery and it gets hot because of its design, but i can get 4-5 hrs OST and it isnt that hot anyways .
OMG., after searching for answers for a year, someone finally figured out how to wipe the cache....
I see a thread closure in your future.

Ha don't be so hard on him there was also an time that we were in that beginner phase, let him learn -±- and it might help other people, who would ask the same. But it doesnt need to be specifically franco but he can mention to look for an custom kernel and that he prefers franco kernel, i prefer now hot weather and beach but also turn off location in 4.4.2 cause location is annoying (thats how the NSA is tracking every terrorist) but i am giving one thanks to him for amusement? so if you are feeling now like? well LG Life's Good you know?

Simply cuz ur tutorial is misleading... For sure franco's kernel may be better than stock so u may get better battery and less heat "issues", but that can be achieved with any custom kernel when correctly tuned.
