[Q] Batery calibration issues. - Galaxy S III Q&A, Help & Troubleshooting

I've been using my s3 for the past one week and my device shows 99% assoon as i remove my charger! i've tried changing the rom, erased my Battery stats, recalibated my battery using playstore apps. even though it shows 99%. please help! by battery life is worst!

All GS3's are like this only. The battery actually never charges to 100. Its purely cosmetic.

Please tell me you've actually tried searching for this before posting since there are literally dozens of threads and discussions revolving around it.
Physically it's very simple. If a battery is 100% full, it's as full as it can get. This is not true for everything but for most consumer-related stuff. (Airplane turbines, reactors and other industry-machines see it as a maximum value for long-time usage but can go quite a bit above)
If you unplug it, your phone starts draining battery since -surprise,surprise- it needs power. So the battery cannot stay at 100% if a (however tiny) part has been removed.
Phones that remain at 100% after unplugging for some time are lying to you to make them look better. And you don't want a manufacturer lying to you, do you?

Better check of you have rogue apps in the background or your screen brightness, my batterylife is quite good (about 2 days with medium/heavy) use. Running stock firmware.

That's perfectly ok. Relax Been discussed here already...
PS absolutely no need to calibrate the battery

This happens to me as well but don't fret over it.... Calibrations should be done regularly but not overly or it'll stress your battery more than necessary.

You do not calibrate your battery regular the year is 2012 not 1995 .
Battery auto calibrates itself use it ignore it .

I'm amazed how people can get nearly 2 days with medium usage. Do you have any apps installed? How many hours screen do you get?
It seems it's pot luck with battery life..

HOW TO: Solve Battery Life Issues

***NOTICE***
The ROM Manager version of CWM does NOT wipe battery stats properly, as with many other things. What you need is jt1134's version of CWM that is all happy and works and stuff.
You can find his happy CWM here. And here. And also here.
And here.
Big thanks to LegionTHEFecalExcretion for the heads up on that.
***END NOTICE***
NOTE: On current DL30 and EB01 ROMs, you will not see battery life like you did on DL09 with undervolted kernels. There are NO undervolted kernels as of yet, everything kernel wise with Froyo ROMs in very much stock. These steps will improve your battery life in comparison to when you flashed Froyo, but you are not going to see spectacular changes in battery life up to what you were getting with undervolted DL09, etc. It's just not possible until we get undervolted kernels and Froyo matures for our device, development wise.
Hi everyone, I've been seeing a lot of threads about bad battery life, whether switching to Kaoscinate, Vanilla, or DL30. Stop it! Just kidding. There is a simple process everyone should follow when switching between different enough ROMs, like AOSP, CM6 and TW Eclair and Froyo. This is how you retrain your battery.
1. Charge your battery to 100% (when it gets there, let it SIT there, your phone is NOT reporting correctly).
2. Reboot to Recovery and Advanced -> Wipe Battery Stats.
3. Reboot, and use your phone until it is VERY low (5-10%, you can let it die if you want).
4. Charge your phone back to 100%
5. (Optional) Power down, then power on phone. (Thanks goes to BrwnSuperman for this suggestion, give it a try!)
Your battery issues should be solved. This needs to be done every once in a while, especially when switching between different ROMs and OS versions.
User dalrym05 posted this alternate method for retraining the battery on page 4 as well, so I thought I would share it here in the OP. I'm posting this as a USE AT YOUR OWN RISK method, as I have not tested it, and am not quite sure what the *228 steps for it actually accomplish and have to do with retraining the OS battery reporting, so I'm leaving it quoted to dalrym05 for the time being.
dalrym05 said:
Here were my steps to better battery.
1.*228 option 1
2.*228 option 2
3. Run battery completely dead to 0%
4. Plug in and boot immediately into cwm
5. Wipe battery stats and dalvik cache
6. Reboot and let charge fully before unplugging
7. Completely discharge again and fully charge again.
After this you should notice a very nice increase in battery as I did. My battery life is back up to par with eclair.

NOTE: I did edit his post to make it a little more clear. I'm slightly anal retentive that way.
HybridByNature had an excellent suggestion on page 4. If people have good tips and tricks for maintaining good battery life, and they are easily reproducible, then I will gladly add them to the OP here. What works for you?
HybridByNature said:
This might also be a good place to add tips & tricks to extending battery life.
IE
-Close programs that you aren't using.
-Don't leave your camera or navigation running in the background.
-Turn off WiFi & GPS etc when you aren't using them.
-Don't run your screen at full brightness if you can help it.
-Figure out what uses more battery life than other things:
Pandora, internet browsing, downloading, camera/camcorder, Angry Birds etc.
If you are rooted, try and narrow it down to the best kernel/theme for your situation. I've found that I have better battery with a non-voodoo kernel but the performance increase is worth it so that's a trade-off that I make.
Let's hear from our readers: What is working for you?

Would not surprise me if this is all it is. I have turned my phone off at 5% for an hour and turned it back on without charging and then it showed 45%. I know when batteries are low letting them sit a little bit can help, but not that much.
It is just being reported inaccurately by the OS.

Yes, but not as a thread, it gets posted in everyone else's "Why does my battery life suck ass" threads, so I made this so maybe people would see it and try it before posting another useless question thread in Development.
Definitely works though. Did it yesterday. Good post. It has been posted in other threads ... but I think we all know people don't read through everything very often.

I have the battery charger and 3 batteries, I always run my battery low and leave it in the charger for a day.
I did this last night and it didn't work too well for me.
Also, when I go to wipe battery stats in the recovery, it doesn't tell me if it wiped or not, just goes back to the advanced menu.
And also, should I be concerned that when I cold boot into the recovery, it doesn't appear to be CWM? It says Android recovery...I know I have CWM recovery installed.
Samerhing happens to me... and I just took it off the charger and I'm on 96 percent in less than 1 min

Wow same here..I just took mine off the charger bout 10 minutes ago and it's at 95% now. I guess I'm gonna let the battery run completely dead and charge it and see what happens.
I did something similar. I charged to 100% while it was on, removed from charger then powered off. When phone was off I plugged charger back in and waited til it was at 100% then unplugged again and powered on. Waited until phone was completely on then unplugged again and connected to charger. Waited til it was at 100% and while still plugged in at 100% booted into recovery and wiped battery stats. Then rebooted phone into OS and unplugged. I had tried this previously with DL09 and it helped a little. Last night I wanted to see how my battery would drain after doing this. With WiFi on and I got about 10 emails during the night, from 8:30pm to 6:00am I lost only 13%!!! Previously I would have lost from 35 to 40%. ymmv

Spare Parts says "Time spent without sleeping: 53m 15s (100%)
Wow.
If I go to Battery History and change the top dropdown to Partial Wake Usage, it says Android System at the top with a bar that's at least 75% full.

This is a proven technique, and it takes patience. Seeing the battery drop from 100% down to 95 or 96% after unplugging is normal behavior. I've done this already. Left my phone unplugged overnight and lost 1% battery. If you're too impatient to take the time to do this, that's your loss. You'll see the battery life "improve" over the course of a few days as the reporting gets more and more accurate.
Sent from my Fascinate using the XDA app
I agree with supplysidejesus. This is a standard practice and should be done with each major rom or kernel install. This leak hasn't been put long enough for most of us to know what our expected battery life will be yet. Give it a few days for your phones to adjust.

try disabling gps in the notifications, that worked for me, but once i turn gps on again, it will drive up to a high percentage.

Flashing decrease battery life?

I have been flashing back and forth ROM and Mods... I felt my battery getting worse compare to stock (stock Rom removed lot of ATT craps and other unused app).
Now doesn't what Rom i use: S8, Unname and CM7. My battery died at the end of the day which should last 1.5 days as my normal use.
Hmmm... well I jumped onto the ship already.
But I have to thanks for all developers that cook Rom. You guys are best.
Battery lifestyle will improve once you build up cache. Was battery life good when you first got your phone? Probably not. After awhile battery life gets a bit better.
Sent from a Galaxy far far away...
I noticed the same thing when I flashed from UnNamed to S8.
I followed some other users' suggestions and reflashed at 100% battery life, allowed the battery to discharge all the way until the phone died, then charged all the way to 100% again without taking it off the charger. I just got 25 hours with moderate usage and about 4 hours of screen-on time.
download the batteryCalibration app from the market, it requires root and makes you charge to 100% first. After that let it drain and it should do better after a couple cycles.
If you delete your battery stats in clockwork the phone relearns them and works better. But it will be ****ty for awhile

None of these do jack on our phone. I've read the kernel source for our fuel gauge driver, clearly none of you haven't and are blindly applying HTCisms to a Samsung phone even though I've posted MANY times that diddling with batterystats does NOTHING WHATSOEVER on this phone.
If someone's experiencing bad battery life after flashing a new ROM, especially a debloated one like Unnamed or S8, they most likely installed a drainer app.
If you run Skype, nuke that crap from your phone ASAP. It's a known battery drainer, and it's particularly insidious because of how it drains the battery - the usage shows up as Android OS but it's Skype that is at fault.

[Q] A Very very Wierd Problem...Please Help !

I was really suffering from massive battery drain....see here - http://forum.xda-developers.com/showthread.php?t=1933012
ive now found out that i am having a very wierd problem...My rom is showing some 30% battery while 4ext shows 50%......Sometimes it is exactly the opposite....Once i discharged my phone to 2% (rom reading) and when i saw in recovery it says 17%....
I have completed many many cycles of battery from charging to full....and discharge to 0.....Also i used the battery callibration app SEVERAL times!!!!........But nothing seems to work...
Can somebody help...Please
I am really suffering from massive battery drain http://forum.xda-developers.com/showthread.php?t=1933012 :crying:
Did you try to delete battery stats? Or use an app to improve battery life?
I have the same issue too when booting into recovery. I don't worry about it. I suggest the same as Ramjet in your other thread.

I had this issue with my old battery and old charger,
Now I dont use my phone while charging , I charge other batteries with the wall charger while using other ones and everything is fine now.... battery % seems to be same in both android and recovery.
I have that same issue too. Lol maybe the recovery can't read the battery correctly. It'll show up higher in recovery and then when I reboot, it will read the same way like in recovery. Tried numerous batteries with the same result. Although I havnt tried battery calibrating. Ill give that a shot.
Is there any solution ??
Try klect's solution and go into recovery, wipe battery stats. Then let your battery drain and die. Then charge your battery back to 100% with no interuptions like pulling your phone off the charger too soon. When you wipe your batt stats you are getting ready to recaliberate your battery. After you let it charge to 100 percent. Let it drain to 0 a couple times to recondition your battery.
You do know that the evo 3D gives around 3 hrs of screen time dont you? even on stock rom on normal usage. If you have the wifi on all the times you'll get around 2:30 maybe 3 on a full charge.
Your battery certainly is draining faster than usual but have you tried keeping it idle and seeing what kind of drain you get? From that screenshot in the other thread it seems like your phone is getting some heavy wifi browsing or something (and do check if facebook or email apps are the culprit. Having push email on drains a lot)
And the recovery/rom reading wrong stats happens all the time. just recalibrate your battery like these good folks here have already suggested
Yes i keep wifi on all the time...
But once i kept my locked for abot 3 hours after full charge...when i unlocked it showed 99%...i was happy and i didn't do anything just surfing my screens it dropped very very fast to some 70 % !!!!
Also please hit our thank you buttons please. Even if you didn't get the exact answers you wanted. It's appreciated for helping one another.
you really should check your apps battery usage using one of the apps ramjet73 told you about
ramjet73 said:
There are a bunch of tips here.
Usually that kind of drain is caused by an app. Try running a stock ROM for a day or two and see if the issues go away. Or use one of the battery monitoring apps (BetterBatteryStats, SystemPanel Standard, Battery Monitor Widget) to determine which app is causing your drain.
It may take some work on your part to isolate the problem since there is no global solution to battery problems.

top culprits are mostly facebook,email exchange,google maps and pretty much anything that syncs alot
Also try using you phone on min brightness auto brightness is also a battery killer
I cant beleive no one asked you this but which kernel are you using? And is it overclocked?
I am on mwakious 13.1 default...no changes to it

S3 Has poor and constantly changing Battery life

So, my phone's battery life is overall quite poor for the most part. some days it absolutely burns through my battery with little phone use, and other days it gets decent battery. i downloaded better battery stats, and for example. today my phone drained at about 10%/hour, but yesterday for example it drained at about 3%/hour. And today i did not even use my phone that much. Please help, as this is getting really annoying.
Here are some screenshots of my battery stats on two bad battery days
Day 1 Screenshots: http://imgur.com/a/bd5pl
I know it looks like dolphin burned alot of battery, but that it just because it was practically the only application i opened and i used it for a couple minutes which i normally wouldn't do. then i few hours later, this was where my batter was at, and i swear i pretty much did not even touch my phone at all! http://imgur.com/NIfYnkl

the wifi is on for 4 hours as well the screen! turn off wifi when not in use! if the problem persists, try changing roms & kernels. even then? replace the battery with a new one.

The screen wasn't on? its an unrooted phone btw. and you think simply having the wifi on is the reason it drained at 11.5%/hour?

[SGS2][GUIDE] GT-I9100 Phone shut-off at 30%-50% battery issue

Device: Samsung Galaxy S2 (GT-I9100) T-mobile carrier- unlocked, Rooted ,Running stock rom with a Philz touch recovery
Problem occurred after about a week of purchasing a new battery since the old one got swelled... but i have two brand new batteries now both are not original but good quality (1 Year Warranty) With both batteries I had the Problem
Let me explain the problem :
______________________
Device would go off in at a certain battery level from 30%-50% (as for my experience):fingers-crossed:
To turn the device ON plugging in is compulsory... but then the battery would be Completely drained..
Also if you try to do a restart at a battery level which is closer to the sudden death the after re boot the battery will be at a extremely low level and wont rise...
I searched all of i can to find a cure to this because the last thing u expect in a situation is your phone dying?
Apparently the problem seems to be that the phone is reading the battery wrong? about a 40% so simple do a calibration Nope Nothing not even a change...
Here is what I tried
_________________
Calibration Methods - Apps and manualy
Reset the device
Let the battery chip reset
and all other methods
but finally i decided to reflash another stock rom :silly:
and I Downloaded This file I9100XWLSD_I9100XENLS1_XEN Since it was a Genuine Netherlands version but i decided not to go with T mobile this time:fingers-crossed:
I Wiped all the phone in Recovery then went to download mode and using Odin V1.85 I flashed the stock rom:fingers-crossed:
Turned it on using a Fully charged battery that i charged separately and i used it for some time max brightness max vol radio and gps wifi bluetooth etc. to drain the battery and at 38% phone started to flicker and turned off again:crying: (no Sim or Memory inserted no apps downloaded)
But i decided to go again i plugged it in ( never changed the batt) and let it charge for about 95% and turned all on again and this time i put on my simcard and memory and did all what i did except that i downloaded whats app and instagram. and also when it reached below 55% i Played some music and locked the phone (NO SCREEN LOCK USED) and after some time i checked batt was at 38% :fingers-crossed: immediately i locked it back and left it again....
Viola !!!!!!!:laugh: last time i checked it was 15% low batt warning came ( haven't seen it in weeks) and then the battery drop was a bit fast and at 12% the screen got a little flicker so i plugged it in.. I think the problem is halfway solved, ill let the battery go some cycles and update soon.. also i will attach some screen shots off the battery level too and take a close look at the time and battery level after 15% on the pics
:victory:
Here is the original thread i created

So yesterday I plugged the device until it reached about 85% and unplugged it when I was going to sleep, and at about 8 o'clock this morning i noticed that the battery level has risen to 96% , I think that is because the phone slowly gets to know the battery level correctly.. and right now it 11.08 am and I had turned on Mobile Hotspot and Data from 8 am , battery level is 82%.
I'll update again tonight when the battery drains completely

Can you also share the SoT ? I know it depends on how a person uses the phone but still I want to have an idea. I might also try this to have a better battery life.

So... Now the problem is still there.....
Phone went off at 43% and also figured that there has been a near vertical drop of battery from 40 % to 12% and thats when the device was standby,
phone goes off only when im using it?
Can a Expert please look into this matter and help me please. looks like all what I did has been useless

I have the same problem. when I reboot my device in most of cases the battry level showed is a 10/30% lower than before and also my phone shuts off showing 10% percent or less and the sreen brightness goes a bit crazy for 2 secs before it shuts off. I have the original Samsung battery but I also bought the 2000mAh extended kit but now this issue happens in both of them I've read that I have to callibrate battery so I will try this and post results
1. Turn off your phone.
2. Fully Charge.
3. When getting 100% signal, unplug quickly.
4. Pull off the battery and put it anywhere.
5. Wait for 180 seconds exactly (be careful )
6. Meanwhile, take this opportunity to dust off the internal compartment.
7. Put back the battery on the right side.
8. Turn on the phone.
9. Pray the Battery god
10. ... and voilà !

I did it and my results were this. My phone shuts off at 5%, slightly less than other times. I rebooted it once while 80% percent and remained the same. Battery lasted 2h and 40 mins with medium/high usage
I would say it fixed something for me but not a lot. Now im going to try it with the 2000mAh samsung battery
Edit1: now after another full cycle the battery lasted for more or less 3 hours with medium usage and shutted off at 8% now im going to try on my 2000mAh battery that had an 8% and it shutted of normally with the shutting off screen and without weird screen brightness tweaks

Well I think it worked for you because you had a Original Samsung Battery Right?
In SL a Original batt would only come with the phone :crying: Fakes have invaded,,
So i read some where that fakes dont have the original capacity? so if it is then it would match perfectly !
so now im in hunt of a original hopefully this is not a phone problem
No its not definetly a phone problem and it isn't a big deal to find an original samsung battery for sgs2 however the Samsung 2000 mAh battery kit its waay harder to find and the ones that I found are more expensive than when it came out
Yeah, I definitely think the problem is with your battery, so you just need to replace it.
Btw guys, what is your general Screen on Time with your standard 1650mah battery (not extended)? I'm running CM13 and I barely get 2h on a single charge, but then I read reviews from the early days of S2 and for instance here they have 4h24 browsing time (with screen at 50% brightness) or 8h video playback.
Is it all related to being a different ROM, or my battery just needs a retirement? Being a different ROM would impact so much on the Screen on Time? Also, I have auto-brightness always enabled, would that have such a significant impact?
Greetings
EDIT: Since I generally use the phone indoors I don't think that would be the difference in such a different Screen on Time

With 1650 mAh and on CM13 nightlies, my best so far is 2h and 28 mins with brightness at between %0 and %25 and only wifi is on.
That 4 hour SoT is probably on gingerbread though.

Being gingerbread would make so much of a difference? It's like twice as much SoT...
Thanks anyways

Never used SGS2 on gingerbread but it is possible I think. I remember reading on forums that people started to get worse battery life with ICS and with JB it got even worse. So yeah probably possible.

Hi Bolshoi! I will definetly update the SOT on the stock rom after the new battery arrives! I asked one of my friends who is in Netherlands to buy and send me a batt. Regards!

Im From Sri Lanka Achimakulo its so rare to find a Genuine Samsung battery for a older device like mine and even if i found one its either old or way too much priced
I think its because my device is so rare in this country
Is it fixed now??
See attachment
battery level drop is natural? ?
