Hi guys
recently i bought new battery because my old one used to jump
from 70% to 100% and had really bad battery life.
i replaced the battery and calibrated it and i noticed that the 20% from 100% to 80% goes down realy fast
should i recaibrate the battery?
what should i do? thanks!
It depends on the rom u r using.
All roms except stock based roms have this problem.

Im using aosp by maclaw studios
the weird thing is that the 70% acts like it 100% and im having really good battery life
from 70%
Its a problem in sumsung charge system.
In custom roms when u full charge battery it is about 80 % charged.

I think you should charge it when the phone is turned off. I noticed that my phone tells me it is "Charged" when it is turned on. However the actual percentage in Go Power Master is 80%.

so it has nothing to do with the battery quality and the battery calibration?
the problem will not appear in the stock rom?
Thats if needed. To check if the battery is fully charged, try these step.
1. Charge the when it is running until it says "Charged".
2. Turn off the phone and keep the charger plugged in.
3. The battery image will appear. If it is not full, wait till it full. When it shows 100% then it is fully charged.
Note that powering up the phone takes some significant amount of battery. If the battery is still draining fast. Calibrate may be needed.

enchanced rom shows 100 percent but still shows charging. So I guess it fully charges
Well the battery level seems to be jumping unusually from time to time . What i do is i wipe the battery stats from cwm , i leave it over night to fully charge without doing anything to it , calibrate the battery with `battery calibration` from playstore , full discharge and full charge again . I do this after each rom that i flash and it seems to do good and seems to point the right amount. Anyway the charge lasts as i hope it lasts , from 1 day if i do stuff with it like some wifi , some messaging , many minutes of calls .... to about 3 days if i do only calls. Cheers

welcome all who see this. alright, my phone is rooted, and i went to upgrade to gingerbread and i used the mikg rom 2.5:1-2. unfortunately i erased the battery stats not paying attention and talking. from then....the phone battery never charges.....even when plugged in it constantly sinks to nothing. even when i charged it turned off for 6 hours, it never gets past 15% HELP! i have tried to rewipe the battery stats, but i only get past draining the battery, because now it wont fully charge. i even bought an extended battery which also drains, but never charges! i am not sure what to do to get battery stats up to par, or to cause this phone to charge any battery! CAN SOMEONE PLEASE HELP! (much appreciated)
im a noob here so i really dont know what im talking about but i had almost the same problem when i bought my extended battery from sprint. first day of use was really good and when i went to charge the next time as soon as i unplugged the charger after a full charge the % would drop soo much...i was getting like 10 hrs which isnt much with an extended battery. i updated to mikg 2.53 and wiped the cache and all the usual and the battery stats and its seem to workin now 1d 4h 54m on battery....hopefully this helps
Use an external wall charger or a different phone to fully charge the battery. Then insert the battery and immediately wipe battery stats.
Should fix the problem.
Using an sbc kernel will allow you to fully charge the battery as well. Use something like Battery Monitor Widget to keep an eye on your charge - 4200mv is fully charged.

It almost sounds like a problem with the phone. I wipe battery stats everytime I flash a new Rom and I've never had problems. You might want to see if the battery will charge on someone else's phone first.

Lately my phone will go through a massive drain until it hits around 55% then it will drain normally. I have not changed anything since this started. Any suggestions? I'm thinking I may need to calibrate my battery.

That sounds like a good idea for your situation.

Thanks for your input. I want to wait a few days before I do it. So it will give it time to see if that really is the problem. This only happened yesterday and today so maybe tomorrow will be better. Besides the only time I really have to do it is later this week.

How does one calibrate a battery? Is this the same thing as "conditioning?"

You charge your battery to 100%, wipe batterystats.bin, then run the battery down to 0%, then charge uninterrupted back up to 100%
Battery Calibration does it help ?
I have a similar situation and i followed the battery re-calibration method too but still didnt help.
Situation - The battery would charge till 88% but will show its fully charged. Recently put Vivokat so now its even more prominent. Every reboot drops the battery by steps, like i would reboot and the battery would go from 80 to 65 just like that, no gradual decline or anything. And even after a full charge (the green light indicator is on) still the battery would continue charging.
Tried - I tried resetting the batterystats.bin file as suggested, fully charged till 100% then removed batterystats.bin file then allowed to discharge all the way then charged continuously till 100%. No outcome
Anything else that can be done ?
So i started using faux kernel and Juggernaut 4.1. I had about 16 hours of battery life. Now my phone drops from 100% to 94% in like 20 minutes. Any help or ideas? Thanks guys.

Download "battery calibration"
Follow steps provided within app
All fixed
Unless you Hella used your in 20 minutes to make it drop that fast

since you're rooted, you can use cwm(ClockWorkMode) Recovery, go to advance and clear battery stats(battery calibration)... or you can shut off you phone, let it charge 100%.. takeout the battery for about 50sec(inspect the battery for leakage"which could damage your phone, if it's leaking" if it's leaking replace your battery), put it back, plug your charger, turn you phone on, while plugged let it show the 100% charge on the notification bar then you should be good..
I have noticed that my battery life drops pretty quickly if i am doing a lot of browsing, etc on the phone.
If its in standby it loses 1% approx every 7-11 minutes.

I think it was normal, all i can think of is you leave wifi on, weak wifi signal when screen off. BTW im just saying
Im having some battery issues as well.. except ive done the battery calibration through the die hard battery script and by wiping my batter stats through CWM. ive tried both of these ways then using the phone for about a week after ive done either. the problem is that my phone wont let the battery fully drain.. or even close, ill show to have about 5% left and ill check the remaining mV through the die hard script and it will have 3615mV left, which according to the the script, should be about 40% remaining. fully charged battery has 4208mV at total capacity does anybody know what the mV level should be when the phone is less than 5% and how i can fix this?? I am getting pretty good life out the battery usually lasting from 22+ hours but if this is right i should getting alot more.

Its great compared to stock but Im on a mission to maximize the battery as much as possible and when i cant use the remainder 40% of the battery it gets frustrating...

Hello all,
Before some days I came back to GB from ICS and my "Android System" drains much battery. I installed mexdroid and I changed to elitemod to see if it is mexdroid's problem, but I got the same problem with elitemod. (After 4~ hours discharging with 2-3 calls and 15 minutes play game only, I got 60% battery.) Does anyone know what is going on? Thank you.

Well, you could order a new battery for next to nothing and see if that helps. If not, try flashing a new kernel. I had a battery drain issue on a gb rom before i went to ics. I have had amazing battery life with ics.

Remember that every time you flash a new ROM, you need to do a couple battery cycles in order for the battery meter to recalibrate. Charge the phone to 100% (leave it on the charger for a while to make sure its really full) then use normally until about 10 or 20% (don't drain to zero, as this is not good for Li ion batteries). Repeat a couple times. Your battery meter is not accurate until you do this.
Thank you I will try this and I will report back to tell you if the problem exists
I usually let the battery drain until its almost dead before charging right after flashing a rom.
Yes you should definitely charge to 100 and let it drain to dead. That will calibrate it. Then just charge it back up.

Hello everyone,
I observed a strange behavior of my arc s , when the phone reaches 100% charge and later when i unplug it my phone spends almost 20 minutes at this point and after some time it starts to discharge ie. it comes down by 1%.
But if i use it hear after it discharges rapidly.
I find this behavior very odd !
Can anyone explain me this behavior ???
Thank you in advance.

Check battery use
Check battery use to see what is consuming the battery
Maybe WIFI and sleep policy,Bluetooth,Network type WCDMA/GSM ,GPS and accounts sync ?
Observe the diagram or the slope in the battery use to see is your battery draining fast or is it normal,also what rom and kernel are you using
Isn't that the normal behaviour of a battery coming from a smartphone? .-. Mine's like.. 20 minutes on 100% before starting going down, and it doesn't affect my overall battery life at all..

I have observed all of that.
Everything is fine, as the display uses the battery predominantly.
My guess is that is a sign for use to change the battery.
And also i see spikes in chart instead of going down the charge goes up and down.
Sent from my LT18i using xda app-developers app
how old is the battery?
how old is the battery ?if the spike goes up that means it is connected to USB and the phone is charging .attached is my battery usage 7 % in 11 hours the slope is continuously going down as it's been unplugged and running on battery only ,phone and battery are a year and half old
The "spikes" you refer to are because your battery isnt well calibrated...
You can charge it fully, use it and when its around 5% charge it again to full. And if you delete the battery stats your battery must sette down over some day or two.
But for a better response you need to upload a picture of your battery stats.
My battery sometimes stays in 100% some minutes, some other times is goes down to 99 very quicky, but its normal for me cause it usually lengths for two days + with normal use

Its a year old.
Yes i totally agree the oly time the graph should go up is when its plugged in and not wen unplugged.
But i sometimes see the spikes when unplugged.
Nevertheless it has not degraded the performance.
