You might be able to fix this by reconditioning your battery,otherwise your battery is just getting old

It could not be getting old I just got it last month

Thats how it is.
cm7 and miui have same problems, and its to save you from over charging, and thats some phones start heating up too much.
Don't worry about it, its for your own phones life.

Ok that's good to know and my phone charge extremely slow and sometime not at all but then I reboot and my battery life goes way up wat is that about
Sent from my SGH-T959 using XDA Premium App

Thats because your phone is mis-reading your battery's charges.
a Re-condition would help phone re-read it more accurately, but idk how you'd do that since to re condition you have to charge till' 100% lol.

Will they change rom to make it 100 cuz I don't want to go back to 2.2 rom cm7 is to good

the CM7 your using is not OFFICIAL, so the problems your facing is up to the developer to solve, not the CM team because as far as i know, they haven't even supported CM7 for us fully yet.

it's just how cm7 is reading the battery. on one revision i would get a max of 95% then 97% on another. just recondition the battery after its been plugged in for while after hitting the 97%. worst case is you have to recondition your batter again after you flash another rom or it gets fixed.

Do you know what cm7 version they've used as a base for the vibrant version? The Nexus S does this by default, to protect the battery as others have mentioned.

YOU need to re-condition, YOU can fix it.
the people on MIUI or CM7 can't.

As stated its a known thing.
I used my Samsung Focus to charge a battery to 100 percent put it in my phone and it discharged to 95% then back up 97%. So the phone isnt charging the phone up all the way as it is. This is also good for the life of the battery and the battery will last longer. Also it gives and accurate reading. Sometimes with phones if it says 100 percent it is discharging thus you actually only have <95%.

I fixed the problem I just switched to best rom(trigger) then reconditioned and it charges perfect thanks for the help

This is by design and should occur on all Roms. Below is a link to a good Phandroid article tiled "Your Smartphone's Battery Gauge is Lying to You and its not Such a Bad Thing". It really does an excellent job with a fair amount of data explaining why your battery will only charge to 95 - 97%.
It boils down to three options:
The phone manufacturers essentially have three choices:
1. Use older charging styles which actually maintain a full battery, thereby decreasing its eventual life
2. Use new charging methods and have an accurate battery gauge
3. Use new charging methods and have the inaccurate battery gauge

RECONDITION.
I told you before everytime you flash a different rom, the battery is going to be different, so reconditioning is going to help you make it more accurate reading. brah.

I did I fully charge then wiped then drained recharge then wipe

You may need to do it a few times.
But since you are on a 2.2.1 rom... no need to worry, when it tells you its at 97% it's actually at 100, soon when you don't notice going from 1% to 2% will take more than regular time, it'll make up for the 3% somewhere along the lines

Ok ill let u know the results of this second try and do I have to recharge when phone off

Why do we got the problems with our BATTERYs ?!

So... I was wondering... WHY DO WE GOT THAT PROBLEMS !?
If we take the NEXUS S Rom and convert it for our PHONES (GT540), where is the TRICK ? Why do we get that problems with the battery and te NEXUS S users not ?!
NEXUS S got the same battery like GT540 and after the GSMarena compare, the GT540 takes it much better then the NEXUS S !
CAN someone explain it maybe ?! Cause I really dont understand

Its the rom itself not the battery.

I know that thx for the reply... But where is the TRICK, why is the ROM quilty for that probs, why is everything else working just perfect and just the battery not ?!
Im sry for that topic and for that question, but Im gonna sell my phone cause of the freakin ****ty battery lifes on every better ROM

Well the rom has a file with the battery calculator. And this isnt calibrated right for all roms.
Also most roms are still under active development so dont get your hopes up about good battery life etc etc

I think battery problem have something with kernel, on 2.1 i use 4 diferent kernel (orginal lg, 666 infernal, quarx, pcfighter) and every kernel have diferent battery life, diferente dischargin steps. So... no orginal kernel no good battery life.

THX for you answer !

I have a Nexus S. The battery lasts 1 day If I use .It is not overclocked (yet) . The battery is same on gt540 it lasts 1 day if I use it.See the attached screenshots from my Nexus S.

What I usually do is that after the battery is charged to 100%, I reboot the phone in recovery and keep it plugged in and charge for anther 15 mins. That seems to give me an additional 1 hour as my phone stays at 100% for at-least an hour before falling back to 99%.

I have had my phone off charge for 5 hours and its sitting on 95%.

Really god i need to invest time in re calibrating mines shocking 13hrs then it died

Battery depends on few things.
1. Kernel
2. Rom itself
3. It will drain faster with data on.
4. Some crapy apps kill your battery.
Choose kernel and rom wisely. Turn off your data if you don't need it. Uninstall unnecessary apps

FOR all those WHO GOT the same problem like me...
I fingered out how my battery is holding for 4 days now...
When you plugin your phone into charge mode... just dont let it to go into "SCREEN OFF"... make your Screen OFF to 30minutes and just hit the screen every 25 mins... or just install an app which doesent allow your phone to autoScreenOff it
After this lil trick... it just works for me now... I hit 113Hours with this trick on Muraiks M6 Version !!!!!!!!!

{Battery Issues} Phones mysteriously cuts off and loses charge

one min my evo is on and battery might say it's at 49% charged. then out of no where, my phone will cut off and when i turn it back on, sometimes its completely dead. sometimes, it's showing 2-4% battery life left.
WTF is going on?

Is it a stock battery from sprint/htc or one you got from eBay or any other seller?

Ive been purchasing 2000mha batteries from eBay and they have been working great for some time now.
I believe that sometimes the length of your battery life experience will depend on the way you charge it through out your day and the amount of charging cycles you've used during the life time of that battery.
Sure I do agree that certain things can be done to improve battery life, but sometimes... It's just time to discarded it and get a new one, imo anyways.

I figured that, but I didn't wanna get a new battery if it was a bad ROM flash or something.. but I'll use my extended battery when I get home and see how it plays out. I just that damn bulky Ness to that battery.

Change roms and wipe battery stats in recovery. If its still acting funky then it must be your battery. I think sprint replaces them for free if you tell them that your battery is disfunctional

Yeah, just did that. Think it was over used. Regular charge, trickle charge, over charged. It's toast.

Been running the new battery over a day now. No restarts at all. Guess it was the battery.

Can anyone upload batterystats.bin??

I have calibrated my battery at 4175mV with calibration app. I let it drain and then charged till 4171mV without any break yet it gives me 1 hour battery life. I have seen in others forums that by replacing batterystats.bin with fully calibrated file, it increases the battery life. So anyone with good battery life and calibrated please upload it for CM7. It is located in data/system. It will help everyone with bad battery life.
PS: I am pretty sure my battery is not faulty one, just not properly calibrated.
Thanks.

after you calibrate battery with app...batterystats.bin gets deleted...so i suggest you to fully discharge battery till phone shuts down...then fill it up to 100%...and then again draining it....your system needs some time to create new batterystats.bin....so for the first 3 cycles it may drain fast...but after that it should get stable...

If your phone is not more than 6 months old from buying date.. then your battery is in warranty.
you see service center people are most probably leaned to soo-off an customer complaint so they'll probably looking for problems with your phone or might say battery got damaged and stuff like that..
so on a safe side, go with STOCK firmware and deny any damage done to battery, just say it doesn't give backup and i want a replacement.

[Help] Battery Drain Problem

Hi All,
Everything was ok till the day before yesterday. But suddenly from yesterday I am facing a huge battery drain problem i.e. 1% per minute on my S4. I am running the latest version of Arrow Rom.
I did format everything and reinstall Arrow Rom but no luck. Then I restored my previous Stock CWM backup and again problem is same.
One more thing my phone's battery is taking too much time to full charge. It takes 5 to 6 minutes to charge 1%. Sometimes it takes more than that.Although my phone is only one year old. When Iam using phone for browsing or chatting with charger plugged in its not charging properly its decreasing.
Can anybody tell me what is the problem?

Your battery is more likely to be uncalibrated. Download Battery Calibration from Google Play and follow the steps on how to calibrate it. It requires ROOT. Any other things that can cause this are wakelocks, be careful what kernel you use. You can monitor wakelocks using Wakelock Detector from Google Play.

Or your battery might be a faulty one, check if its swollen

Use power saving mode install stock rom
Auto brightness
Format sd card
Remove unnessesary apps
Stop all unusual apps like google plus hangout and play books etc etc those you don't use.
Disable chrome use dolfin or other's.
If you are using custom kernel or mods like audio mod or performance mods don't use them.
Auto sync off when not needed
If these steps don't work then change the battery
For charging use 2amp charger with a 16amp socket
Use stock usb
Clean your battery's copper area with petrol and also clean your
Usb cable and ports sockets
Hope this will help
