Hi there,
maybe this is a stupid question, but last night I updated (via Kies) to 2.3.4. While the instructions in Kies said that I should do this with a fully loaded battery, I did it with 60% charge.
Now my question is, if this will have an effect of the calibration of the battery. Are the battery stats reset when a new Android version is updated? And will the battery stats now think that 60 % is 100%?
No they are not recalibrated .Calibration takes a few days .

The answer is: NO
No recalibration process takes place after regular Kies update. And you don't need to to update with fully loaded battery. Theoretically it is sufficient to have enough power for >30 minutes of operation.
make sure if you want to calibrate a battery to leave it to the max and dont discharge it during the charge....and when leaving it to drain do it again without reboots or interuptions....and always do that a few charging cycles and you be good to go...
just answering the calibration part

Hi ,
I'm on stock ROM KF3 (Rooted) . Since last week I'm facing wierd problems with battery .
Today morning My battery was on ~ 50 % , then after 15 minutes , to my surprise my phone was off . I turned it on & to my shock saw battery critically low notification ( with 1% battery remaining ) .
Also after 10 minutes of being turned on , the indicator increased to 7% automatically .
I then plugged it in and made a complete 100% charge .Within 20 minutes from being unplugged it was on 94% ,So i did a restart and to my shock again the indicator showed 64% . Then within nearly 15 minutes on being turned on the indicator is increasing automatically in steps of 1% & now indicator shows 72% .
Is this an issue with the phone , battery or what .??
FYI I'm using battery monitor widget & circular battery indicator .
I'm posting my battery usage , battery graph from battery monitor widget & battery history from battery monitor widget for diagnosis . Please help .

Please reply.....
Did you try to calibrate your battery? There's an app available on the market called "Battery Calibration".
Charge your phone to 100%, start Battery Calibration and choose battery calibration. Plug your phone off and let it fully discharge. Then charge it to 100% without a break.

If battery calibration doesn't help:
Flash a newer ROM.
I recommend the latest, stable version for your region => XWKJ1.
There is a non-wipe Frankenstein version from Intratech (=> http://forum.xda-developers.com/showthread.php?t=1075278).
Please read the first post carefully. Official Firmwares can be found in second post and Frankenstein versions (with can easily combines with different Modem and/or CSC files for other regions and/or providers) are in the third post.
After flashing the new ROM you may root your phone like described in the first post, or just flash a working CF-Root kernel from Chainfire.
For XWKJ1 CF-Root kernel XXKI4 and XWKI8 will do - as long as there is no CF-Root kernel exactly for XWKJ1.
Good luck !

How is KJ1 the latest for my region .? I live in India and the latest still is KF3 ...
Which is the best out of KI3/KI8 or KJ series interms of battery life and overall performance. ????
You are on android 2.3.3 just download the new version of android ( 2.3.5 ) and you will see better battery stats

Normally you have to choose battery calibration, before you unplug. but yes, that's how it works.

i was also getting weak battery backup pf 10-15hr max.....then updated to custom rom.
1.senesation 1.8 with ninphetamine 2.1.3, now i am getting more than 22-26 battery backup with use of voice call, messaging, browsing, music play.
2. i also collaborate battery by charging battery to 100%(until unplug charger comes) then drain battery until it gets switched off. then again i charge to 100% then immediately went to CWM n cleared battery stats
3. Also i am using Juice Defender
I uploaded screenshots. You can see, Its already done 13.40hr still battery is 57% left.

I have a similar problem. My battery stays at 100% and prevents itself from charging. Last night I left my phone unplugged and when I woke up this morning it was still at 100% and when I plugged in the charging cable it said Phone is charged, remove charger.
This causes some real problems. Like yesterday I was using my phone then bam! The screen shut off. That was strange, I thought. It didn't look like the usual screen timeout and sleep because it didn't dim first. But then I tried pressing the power button and that didn't work either. So I took the battery out and put it back in. Still nothing. I started getting really bummed. What could be wrong? So I connected it to the charger and still nothing. Now I am getting really, REALLY bummed. Well after a minute or two on the charger I saw the big green battery come on with 0% charged level. Well, I am happy because the phone is working again, but confused because I just took the phone off the charger less than a half hour ago. Why 0% now?
I am still on totally stock, no root, no nothing. I have not tried battery calibration, but somehow I don't think it will help my problem.
Hello,
I have ordered a new higher MAH battery for SGS II . I may be running stock ROM/Kernel or any of the custom AOSP ROM/Kernel.
During the kernel/ROM updates I have read that we dont usually need to clear the battery stats (since we are using the same existing battery).
However I will now be using the following battery :
http://www.amazon.com/gp/product/B0058SJ5Q4/ref=oh_o00_s01_i02_details
I need to how to properly calibrate the battery status so I can achieve full charge and maximum run time from this battery. Do I need to clear battery stats (from recovery mode) first and then insert the battery for first time usage or otherwise.
Have read a couple of posts on the subject however none provides a clear defined and fixed approach to the issue.
Any detailed guidance would be appreciated to be of benefit for the community in general.
Thanks.
=================================
Guess there are already enough methods and ways and some even debunk the myth that does the phone really needs any type of calibration/calibration apps at all or not.
Will try diving into it directly to see the effects myself if any.
You don't need to do anything other than sticking it in your phone.
When I got the 2000mah battery, I found my battery life to be equal or even slightly less than the stock one. I fully charged the battery, went to cwm and wiped battery stats, used battery completely till it died and then fully charged once again. It did seem to work as my battery life was much better.

He's right. Your battery calibrates itself with a full charging.
i read in a number of articles that you should reset/wipe your battery stats with CWM once your battery is at 100%, then switch off your phone and connect to a charger usb/plug until it will be charged to the actual 100% (usually only 1-2% at most)...

All 100% wrong .
As it only wipes the stats that show and plays no part in calibration of the battery .

thnx for the correction, what do you think about "Battery Monitor Widget" app? Does its function to calibrate actually work?
Got intrigued by the issue...
No, it doesn't. Due to hardware 'limitations', battery apps can only provide a rough guess at best of charge remaining, discharge rate, etc on SGS2.
And genuine (made by Samsung) batteries don't have to be (and cannot be) calibrated. There's a fuel gauge chip in the battery which does this automatically.
Some people having issues with the battery report charging to 100%, removing the battery for a few minutes (so the fuel gauge chip doesn't have power for that time) & putting it back in the phone fixes their issues, but even that sounds like voodoo to me.

I have a extended battery. I usually get 2 days use on a charge. about a week ago I cannot make it thru a day. The battery is only about 6 weeks old. I tried another battery and same thing. I use task killer and app cleaner and have restarted several times. When I look in battery usage is shows the Android OS using 24% Display 26% and phone idle 24%. I did update all my app and this seemed to help just a little. Anyone have any suggestions before I return my extended battery or do a factory reset. tks in advance.
have you tried draining the phone completely till it shuts off, then plugging it in and letting it charge to 100% with the phone powered down?
Battery instructions say NOT to every let battery drain to 0. So not sure I should try that.

That is about the life that I get on mine on a bad day. Now that you have had the phone for a while, more than likely, your battery has not changed but you have installed more apps which are draining you battery even faster. You shouldn't use task killers either, they screw with the roms built in memory management. However, if you must, then use "Task Manager" the built in stock task manager to end apps. Also i agree that you should completely discharge your battery and then let it recharge completely without turning it on and without using it.
PS: You have a nice avatar. Conservative til i die

This is not true. The phone has its own power management. When you reach 0%, the battery has still at least 3100mV (on mine it's more than 3200mV).
Li-On and Li-Pol batteries are designed to operate between 4300 and 3000 mV when they reach more or less, than they are damaging.
So you can charge and discharge your phone everyday between 100 and 0%, without any battery damage.
Other thing is Android power management, every time you wipe battery stats or restore backup, or you spend some time in recovery, Android doesn't know, how much capacity is remaining and you need to make more charging cycles, to teach it again and get full capacity from battery. I still don't understand this kind of management in Android.
I've tried all the battery stuff. No dice still discharging fairly quick. In the Battery Usage section It still showing Android OS using around 39 to 40% usage all the time. I have done a full factory reset on the phone 2 days ago and still same.
I noticed, you are using the task killer, stop using it, you have probably loop of killing and starting of some services. Task killer kills, android starts, again and again...
I have uninstalled task killer restarted the phone and still got the high Android OS usage showing.
You won't notice any difference immediately, make one discharge, charge and discharge cycle and you'll see.
Do NOT discharge the battery completely. Over discharging Lithium ion batteries can be harmful to them. Here's a great article going into probably a little too much detail but it gets the point across: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
As far as your problem goes it may be an issue with the phone itself I've seen a couple photons that needed to be exchanged due to issues that sound similar to yours. If it's doing the same thing on a different battery I'd take your phone into a sprint repair center, you could also try a factory reset if you have not already done so. If your only seeing this behavior with your current battery then I would return it or request a warranty replacement.

root your photon (if not already rooted) and download battery calibration from market, also after rooting go to android development and download th3bill's extended battery mod

Yes, there is an additional reserve that the Smart chip will protect by turning off the battery once it reaches the "0% mark". The Smart chip will also continue to drain the battery further past the 0% mark eating into this battery reserve. Now one full discharge like this probably would not hurt the battery as long as the battery is recharge within a reasonable amount of time. However it certainly does nothing to benefit the battery health whatsoever and it is never recommended to let a battery fully discharge. There are some practices of only charging the battery to 75%-80% that can improve battery life, but individual run time will be sacrificed. My recommendation is if the battery is under 65% than to charge the battery if it is possible to do so.
After doing a factory reset the same problem remained. Sprint exchanged the phone for a new photon. Put my extended battery back in and so far no problems at all with the exception of not being able to join my contacts with my FB contacts.
I have been discharging my Photon and previous phones to 0-5% at least 3 times for a week and did not find any difference in capacity, compared with the new battery. Lasts from the morning to the evening. If I should charge it on 65%, then the phone would be unusable for me.
Like Schale said it could be an actual phone issue, but i highly doubt it. I would try some things before assuming its a problem with your phone. Do this... Also this assumes you are unlocked or at least rooted.
1: Factory reset so to start fresh with no crap applications (task killer apps do more harm than good, as do most battery saver apps)
2: Drain battery till the phone shuts itself off (Dude what right about it reserving a certain amount of juice to not cause damage)
3: Charge to 100% (Dont use the phone during this time.)
4: Use a battery calibrator app (rooted) or recovery (unlocked) to wipe the battery stats.
5: Drain power as fast as possible till phone shuts off
6: Charge to 100% (Again, dont use the phone during this time.)
You can now use the phone how you normally would. If you don't notice a drastic increase in battery after discharging and recharging three or four times over the next few days, I would be comfortable in assuming it's a phone problem. Good luck!
im using this Battery Calibration and the directions say to "let the device fully discharge after calibration, and then charge it to 100% without break"...and the voltage meter should read around 4200 mV on a normal battery.
i read that my battery should be calibrated after any new rom i flash? has anyone else done this or does it? i just calibrated it and am on the part of the process where right after i "calibrated" it, im supposed to discharge all of the battery (where i am at now) and then after that im supposed to fully charge it again. but i noticed that my battery (after i pushed the 'calibrate' button) has reached down to 30% alot faster than before the calibration. is this only because its still "learning" since this is its first full charge after the calibration and itll be faster after it learns? or should i not even have bothered and this is just a waste of time? thanks.
ps. and during the first run after the calibration (during the "learning" part) is it ok to turn on all my features so my batter will drain faster so i can finally recharge it and be done with it or just let it drain thru how i would use it normally? cuz the app says after i calibrate it, then let battery discharge completely and then charge it one last time.
I actually used this app and it did work for me. My battery lasts much longer. It shouldn't matter how its drained.

A little more info would be nice. What rom are you using? Do you have root permissions? Are you s-off?
The first solution is:
On OVO 3D sometime if battery is charged to 100% he starts to use battery power instead of charger so if the light is green you need just to connect the charger again and it will start to charge again.
And the second:
After you installed some kind of ROM you need to calibrate the battery again. You can do by discharging your phone to 3-5% and then charge it to the full. You need to repeat this process few time and then you have calibrated battery.
Sorry but i forget to say that before recharging you need to delete old Battery stats

The first thing is correct. When the phone is fully charged the charging stops and the phone uses power from the battery.
As for your second statement - you are partly right. Even though most developers say the same thing you said I found the battery calibration is the best way to get the most from your battery. I tried everything that developers suggested and it didn´t work so well. Battery calibration did the trick - now my battery life is great
Anker batteries seem to work the best
Hey. Thanks for the replies. I'm using the 4EXT recovery and KingCobra3D - ICS 1.6 ROM. The thing is that my phone doesn't even charge up to 100%. Is it necessary to discharge the phone to 1-5% and then charge it to full and then calibrate via recovery or can I just calibrate the battery without having to discharge it first?
Also, I have root on my phone and S-ON.
My anker battery has reported like 4000 charge since I got it and I tried using the calibrate app but it still reports the same after a few cycles? It should be reporting 1900.

If you don´t use battery calibration you should go into recovery and wipe battery stats. Then boot up and fully charge the phone and let it discharge to 5-15%. Charge it to full and that should be it.
If you use battery calibration just charge to full, enter calibration app, hit calibrate and that is it

Okay the phone charged up to 100% but it took ages. I've downloaded the Battery Calibration app from the Market and hopefully everything's gonna be well now.
I have battery life issue too. I will try battery calibration.
