proper battery calibration? - Thunderbolt Q&A, Help & Troubleshooting

Whats the proper battery calibration method? I know theres an app on the market too.

In general, you drain the battery to auto shut off, then charge from there. Not sure if there's an app for that, and this is something you should only have to do once in a blue moon.. it should not have to be a regular thing.

Just do it form recovery.

do what? drain the phone, then charge with it off until it turns green? then wipe stats in recovery?

let the phone die and leave it off until the green light turns on. then turn it on still plugged in and let it charge until the light turns green again and unplug. you can calibrate the battery also using the battery calibration app in the market (my method) or you can let it charge to full while off and when the light turns green reboot into recovery and wipe battery stats. i find the app in the market the best cuz it actually shows how many mv your phone has. and you dont have to turn your phone off just let it charge overnight and use the app.

Yep. There's an app that will do that for you and notify you as soon as its charged so it doesn't bleed charge on the charger. It's called Battery Calibration.

Yeah it gives you a little notification sound as soon as it gets to100% and you hit calibrate. Then just use the phone till it turns off and plug it in and let it chage all the way to 100% without stopping. (with the phone on or off I really don't think it makes a difference.)

Ive charged my phone whiles it's been on and then turned it off when it turned green. the phone will begin to charge for another 20 minutes or so, then i've either booted into recovery and cleared the battery stat or used the battery calibration app.

[Q] The battery is drops suddenly on Galaxy S2

After I fully charge the phone, and disconnecting it from the power, the battery suddenly drops to 96-97%, it is normal? I already made a battery calibration past week. Even after I upgraded the phone from XXKG2 to XXKG6, still the same problem here. I bought the phone last month. (by the way, it is rooted and I have on it the 2.3.4 stock)
Post some pictures of the battery usage.
And also some of bestbatterystats.
Try this: After you get the "Fully Charged" notification, try not to take it off charging immediately. Leave it on there for about 10 minutes or so and then take it off of charging, you should see it as 100%. If this does not help. Please post some screenshots of your battery usage screen, we can troubleshoot from there.

Tap your finger on graph above and screenshot that.
Did you calibrate your battery, before or after you upgraded to KG6? If you calibrated it before, then you should try calibrating it again.
1. Charge 100% (best way switch your phone off)
2. Run Battery Calibration
3. Drain the battery until it's totally empty.
4. Charge again 100% (best way switch your phone off)
5. Reboot and enjoy

I think maybe batterystats.bin was not removed, I tried to remove it with Battery Calibration app, but I didn't checked if it was or not. Tommorow or on monday I will try to post some stats from Battery Monitor Widget
That does look very much like a non calibrated battery. Try calibrating it as 'Bruaca' mentioned, and you should be getting the correct readings this time around.

I did another calibration, with the device turned off until battery riches 100%, then I turned it on, then I removed the charger, and it was on 100%, I put the charger back, again after 5 minutes I heard the signal, then I went into Root Explorer and deleted the batterystats.bin, and pulled the charger, now I have 100% + 4143mV, it's normal? or should be more mV?
4143mV sounds a little high. Mine is ~3600. Though I'm getting the opposite problem. What might happen is that I'll leave it on overnight and it'll gain 2 or 3 percent of the battery. I started getting problems charging after I installed font changer, which was also weird. Like, it'll take ages to charge to 100%.
Edit: 4143mV sounds about right for a fully charged battery.

Baterry problems

Hi guys, when i try to charge my battery its stop charging with 90% and never goes beyond that. It starts to happen 2 weeks ago.
Any help would be great to fix it.
Thanks,
Did you search this forum?

Boot into recovery, then go to advanced and reset battery stats, then reboot. Use your phone until the battery dies then fully recharge. If this doesn't fix the issue, you may have a bad battery.

Have you Tried to Recalibrate the Battery?
Sometimes the phone battery monitoring gets out of sync and the remedy is to recalibrate the battery.
You can either try one of the available apps in the Android Market or you can do some manual steps available online(just search for Android Battery Recalibration).
Here is one example, scroll down to Battery Calibration section: http://www.darkyrom.com/community/index.php?threads/guide-battery-life.2551/
I tried wiping the battery stats and calibrating as well but what worked for me was:
1. Charge for at least 4 hours to ensure a full charge
2. Unplug, turn off, and then pull the battery
3. While battery is out, plug charger back in and wait for the battery icon with the question mark.
4. Reinsert the battery (results will vary here, mine comes up as 5% for some reason)
5. Unplug the charger and then plug it back in, it should show as 100% now
6. Turn on while plugged in, wait until fully booted and then unplug from charger (it should read as 100% or 99%, depending on how your battery gauge works)
This is just what worked for me, I am running Navalynt's pi-crust (based on AT&T 4.5.91) so please be careful and research if there would be any issues with other ROMs

Wont go past 95%

Im unlocked rooted running wetdream. Ever since installing it, the battery indicator wont show charge beyond 95%. When charging with phone off, it reaches 100% but as soon as I power on, it only shows 95%. I've done battery cal app, let die completely twice, charge overnight, pull battery while still plugged in (which I never got missing battery notice for) and wiped battery stats in recovery. Is this something I just need to learn to live with or anyone have any other ideas? Btw, im loving nottachs wetdream rom. I know this has been posted elsewhere, I've tried all those tips. Just wondering if there are any new tried tips I can look into. Tia

No need of any app. Just drain the battery till it powers off. Full charge without switching it on. Should get the 100% bck.

I never had this on stock, but with the 10% changes in battery, would I have noticed.
When you are installing custom ROM, this is expected. You can try this,
Steps:
1. Drain your battery till gets shut off, then charge it till it says "Fully Charged" irrespective of 95% or 100%.
2. Once charged, Reboot the phone in recovery mode, keep the phone plugged into charger
3. Start it in Recovery mode using CMW, then remove battery stats
4. Switch off the phone
5. It show battery icon with %, with plugged in remove the battery
6. it will show missing battery icon, then insert the battery.. it will show 5% or 20%
7. Charge it for 3-4 hrs, then reboot the phone, you will see 100%
This Fixed for me...
Hi I've been using Neutrino for weeks and have not been able to get past 97pc battery using all techniques on xda. I finally fixed it yesterday when I installed clamsysns 1.5 kernel and charged over night and it was back to 100.

Just an update. I installed the newest version of wetdream yesterday. Got it to charge to 100% then thru resetting up phone and such, dropped to 18%. Recharged but didn't make it to 100% this time. Got to 95% but 4200mv, so I assumed full charge. At that time it was bedtime, so decided to just plug back into charger for the night. This morning it read 100% again. So its basically getting its full charge, just not showing all the time. A glitch I guess ill have to live with.

[Q] Charging Problem X10

If I keep my phone on charging even after its on 100%, it starts rolling back. As in from 100 to 99 then 98, even if its pluggen in.
Don't know what kind of a problem this is, hardware or software.
Or there's some issue with the battery.
Please help.

I know the reboot helps.
But usually I put it on charging at night before sleeping.
And when I wake up in the morning, the battery % becomes even less than what it was when i plugged it in.
I'm usually in a hurry then to leave for college in the morning . Can't go to college with battery % less than even 10
Thanks for the reply anyway !

Maybe You have some program that syncs something all the time. Did You try to turn off data and wifi. You can always check it if the reason is the hardware or Software. Just make a backup of Your whole ROM, delete the data and leave the phone over night. I hope it is only software problem.
EDIT: Does Your battery go hot while charging? Oh, and try to wipe battery stats

The x10 charges the battery to full then if still plugged in it will stop charging until batt drains to set level ,then will charge to full again and over and over all night. X10 wont over charge batt when left plugged in. Kernel/bootloader handle this. There is an app current widget that can log charge levels.
EDIT: I had a tip on charging here but removed it after further research read more about batt here..

EDIT: the best tip I usr for battery life is, let batt runout until phone shuts off, then pull batt, then plug in charger, then replace batt into phone, then phone will boot, enter xrecovery on first boot and wipe batt stats. After wipe while still in xrec pull batt then unplug. Now plug in phone then insert batt. Phone should boot in charge mode( big batt icon only on screen) dont start phone untill light green for 1-2 hours to get full charge . I do this about once a month, when phone starts to shut off around 15%

As mentioned above as well, this is normal. After charging to 100%, the phone stops battery charging, and will activate charging again only when battery falls a bit (say 97%). Also, battery heating while on charging (and also when using the phone continuously while playing a game) is normal. Relax.. your phone is fine
@ToledoJab
I am having the same issue with battery... phone switching off at 15%, even at 22-23%, when playing a game or something. But switching it back on, and leaving it idle, phone might run for another 2 hours. So it is the extra load while running a game that the phone cant take any longer (i remember getting the 15%,10% and 5% reminders earlier while playing games)...? Does the battery calibrate method actually help in your case? does it go all the way down to 0% or 1% before shutting down.. ?
I just did this after posting that. And yes my phone reported warnings @ 25% 15 10 5 and then shutdown @ 1%.
This way is like reconditioning an old rechargeable ni-cad batt.
All this does is completey drain batt then, with least amount of drainage (phone on, apps& radios running) allows battery to full charge.
There is also a way called recalibrate battery. But this way over charges the batt.
EDIT: I think the phone load will effect reported batt left. I think batt gage use average loads to estimate remaining power. Meaning games, full brightness of LCD, radios -3g -GPS -WiFi -Bluetooth will use more than avg power
edit 2: I found this thread also has some very good points and links. after reading this i will not intentionally take my batt to 0%. I hit 0% about 1-2 times a month on accident as it is. i will just make sure when i do go 0% to wipe stats (dont know if it helps or not) then preform a long (overnight) full charge with phone off.

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.
