This belongs in question and answers section.
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

Low battery life

For the past few weeks i've been noticing a bigger drain of battery than the usual and i don't seem to be figuring out what's going on...
If someone knows any way to increase battery life feel free to post any solution. Thanks in advance

have you been fully charging and fully discharging your phone?

What app did you install? Did you install a new rom? what rom are you on? My guess would be a rouge app. Have a look in the battery usage graph or get spareparts and look at the things that are keeping the phone awake.

I would suggest you download CPU Spy to see if an application is preventing your phone from entering deep sleep mode, for example. You may have a lot of widgets refreshing way too often, as well.

The only widget that refreshs at my home screen is SetCPU, in order to monitor the Temperature, but i will try that app in order to check whats going on thanks.

Ok finally I've managed to see what was the problem that was causing such battery drain/loss... The problem is that i wasnt full charging/discharging, now the battery seems to be working fine. Also I've check cpuspy and nothing is interferindo with the deep sleep.. Thanks for the help

Never fully discharge Li-ion batteries.

But is not fully discharging, under %15 damages battery? And also i put from batter over %95 because after %100, it waits until it drops and again charges if i forget there.

Charging Battery

Hi people,
Got a issue with Q JB 28.11 build. It takes 4 to 5 to charge the phone. Is there any fix to it? Don't want to go back to CM7.

What?!?!? Do you have a 4000mah battery???
I' m on SB 3.0 with a 1700mah battery, and it takes 2-2:30 hours to charge (from 2% to 100%).

Did you change the CPU governor? I know that for me, smartass governor gives incorrect battery readings and sat at 65 percent charged when it was already fully charged.

It just 1500mAh. It doesn't make sense, isn't it? It hardly takes 2 hours in CM7.2. But on Q28.11, it takes forever.

I also noticed this with the 04.12 build, it took forever for it to climb up to around 70%, but as soon as I connected it to my laptop, it said it was fully charged. No idea, what causes it. I still find that these JB builds are snappy and shiny and stuff, but I wouldn't take my phone outside the house while running these. After 9 months of White Rabbit usage I trust those better.

Did you try to reset the battery stats in recovery?
Or there might be a bug with this rom. The next one could be better?

By what method do you charge your phone, usb or charger? Charging is slower via usb

Use it...... Charge it often... try not to discharge the battery to zero. Calibration is not needed... This is a newer phone with new battery technology.
Sent from my Nexus 4 using xda premium

thanks I thought to calibrate it you had to discharge it fully then recharge
Sent from my Nexus 4 using xda app-developers app

Yeah just use it like normal. Don't worry about the battery bar too much.

Calibration is a myth
Sent from my Nexus 4 using xda premium

It is a good idea to charge for solid 8 hours and discharge to around 10% the first 2-3 cycles of the battery to condition it. But after that, use as you please, no memory effect or calibration or the like.
Only thing I would add, do not drain completely flat (0%) as it can negatively effect battery capacity, tho modern batteries usually have guards to prevent full discharge, for that reason
Calibration (full discharge) was for Ni-MH battery technology, and is actually a bad thing to do with Li-Ion/Li-Pol batteries

There is no memory effect any more. Just avoid killing the battery fully or leaving it charged for extended sessions, because the heat hurts the battery.
Sent from my Nexus 4 using xda app-developers app

The thing about discharging to zero damaging the battery is another myth. The phone will report the battery at zero well before it reaches the "real zero". So there's an inbuilt safety margin that means you don't have to worry.

[Q] Battery calibration

Hope this isn't a dumb question but after the EVO 4G I stepped away from android for a while (worst mistake ever) ....now that I am back I was curious, the way roms and kernels are being developed nowadays do you still need to calibrate battery after flashing new roms??

Never heard of battery calibration on any android phones in the past 2-3years...if ever.
Just let it drain from normal use to 15% then fully charge it.

I know a couple of years back or whenever the EVO was the big cheese you had to calibrate after flashing. Recoveries even had options for wiping battery stats. I just wasnt sure if it was an issue anymore. But thanks!

A battery is a battery. As far as I know its taken care of by hardware that is responsible for charging it.
Sent from my SAMSUNG-SGH-I337 using xda app-developers app

These phones (Galaxy S models) take care of it themselves. All you do by calibrating is wipe the battery stats, but it won't provide any benefit.

Wow I havent heard anythong about battery callibration since forever ago xD I usually always flash roms on a full battery let them die then full charge for a couple days then start doing the testing of the rom!
Sent from my SAMSUNG-SGH-I337 using xda app-developers app

I remember reading over in the sgs3 forum about wiping battery stats/ calibration was that it was proved it was all a myth. I'll have to look for it....
Omega v3.0, 3minit framework, kt kernel 2.2 Ghz

Calibrating your battery (or calibrating the software to correctly read your battery's charge) was something that needed to be done on the captivate (SGS1) after installing a new ROM but not on any of the galaxy phones since then. Even then the software would correct itself after a charge or two.
