[Tutorial]Battery Recalibration

Though Most of you Might know this already But I'll post it for the new Users out there
So you have flashed your Rom Recently and are finding some trouble with your battery?
Does it dies too quickly? or you see those numbers going down very Soon?
There might be some Other Issues related to Battery drainage but most common problem the user might experience after flashing quite a few ROM's is Mis- callibration of the battery
To fix this install a market app known as battery callibration
https://market.android.com/details?id=com.nema.batterycalibration&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd
You need to have a ROOTED device for that
program does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
When you reboot the phone after calibration a new batterystats.bin is created
IMPORTANT after calibration let your phone discharge to 0% and then charge it to 100% without break
DO IT AT YOUR OWN RISK (although None is involved) I'm NOT RESPONSIBLE FOR
ANY SORT OF DAMAGE DONE.
Hope this helps you guys

This can also be done via CWM usinge the delete battery stats option.

Sure But as stated this is for new users Who are not well acquainted with recovery

Just following logic. If someone has started flashing Roms and rooting devices, I would be surprised if they had not discovered CWM

after doing research on all methods to recallibrate checking pros and cons finally i got the answer brothers...its very simple no need for cwm or drain full abttery kill your batery download recallibrate delete batterystat.bin....all fake bother....just do a simple step remove your battery for 2-5 minutes and than on it....you are recalibrated....simple

but what about batterystats.bin? Why is it there? ^^
And from which research resource you are talking?

Hey..it works,thanks for your efort in researching this
I'm quite desperate coz ever since I'm installing creed 1.7 seems like my bettery drain very fast,too bad coz I like this ROM. Last night I charged it to 100%,then I go to sleep(so my HH is idle) but when I woke up 3 hours later,my battery stat already drop to 84%,strange. So I try plugged out my battery for 5 mins and voila..now it's written 53% but it's been like that for half hour so maybe it's quite stable now. Thanks again dude

since 13 months i m using fit bro and the most annoying thing of android was battery backup so researched almost all sites of android and lion baterry ....checked alll methods of battery boosting from apps and ram clearance,...the battery stats.bin bro yup that you dont have to take care its android system which adjust itself and recalibrate when you make your android without power means no battery for a while and when you insert it again the system itself recognizes....killing your battery specialy lion reduces its self life also its the number of cycles so whenever you charge charge your phone to fullest not like every 5 min you are charging your phone once a day to the fullest just check what i said bro its really works just believe and c

However, as she explains, that’s not the case. Because those battery stats, stored in the batterystats.bin file, are only used to maintain information about what is using the battery when not recharging. That is, it essentially holds the information displayed in the Settings > Battery screen. Nothing more, nothing less. Thus:
It has no impact on the current battery level shown to you.
It has no impact on your battery life.

I did battery re calibration once and it made no difference at all, having a google engineer dis-miss all the myths is good enough for me buddy.

I installed Battery Calibration 1.2. When open it writes the following:
1. Plug in your phone to the charger
2. Wait till it charges to 100%
3. Click 'Battery Calibration'
4. Unplug your phone

Boot-Loop

I'm running on CyanogenMod 10.1 , and out of nowhere, after using the phone for around 10 minutes, it loses all the signal, shuts down and starts boot looping for no reason at all, is there any way to fix this?
The only way i can get the phone to turn on is by removing the battery and letting it sit over night, or by placing it in the freezer for some minutes <.<

Maybe your battery died? How old is it? Is the problem only in this rom?

I've had the problem with a previous ROM, it is roughly one year old, and how can i check if the battery is damaged? Also, in the last couple of days it happens for no reason, even when im not touching the phone, it loses the signal and goes into boot-loop

Tell me how long your battery charge from about 10% to full?
10% to 80% charge faster than 80% to 100%?
When your battery full charge. Shutdown and remove it. Install battery again turn on. Will it drop power about 5 to 10%?

No, the battery doesn't drop back down to 10%, and it sometimes take like an hour? maybe less from 10-20% to full charge

i agree, its probably your battery. buy an anker one much better than stock. but i do feel the need to mention that putting your mobile phone in the freezer for any length is very very very dangerous and can leave your device very FUBAR

no guys
it is a htc common issue after rooting the device
no one has found a solution yet
also if you reboot the device while charging it it will jump to a higher percentage of charge

give a try with different roms and kernels to see
if the issue persists probably it is a hardware problem

Any rom you would recommend? Also, which way is the most efficient to delete the rom etc without leaving anything, I read that my problems could also be caused by a bad recovery/rom install

begin with arhd rom from mike's thread
it is the closest to the stock
before flashing the rom do:
nandroid backup from recovery just in case
full wipe from recovery
flash the rom

Huge battery drain - please help!!!

Hello guys,
I have a problem with my new Galaxy S7. The battery is draining way too fast.. I'm constantly getting around 2 hours of SOT a day and the battery lasts about 12 hours... I'm desperate... I have tried everything from turning off Wi-Fi, Bluetooth, uninstalling apps to even factory resetting the phone. The problem is still there.. Please help me

BTW, my battery level is dropping 1% every 2-3 minutes

No, I have 1% drain every 2 minutes when using the phone on light tasks( Internet, messaging, Facebook and email). Little to no battery drain is visible when not using the phone. But I can'tell get more than two hours of SOT on a full charge

I'll suggest you do something that worked for me, charge your phone to 100% and then restart it. Idk if it will work for you but tell me if you see any difference.

Facebook app is draining battery like that for me at the moment.

Uninstalled Facebook and it's still there... Nothing funky in battery stats apart from high usage on Android System

That's weird, try disabling everything you don't need like Bluetooth, NFC if you haven't already. Turn screen brightness lower, disable fast charging and "nearby device scanning", optimize the apps in settings/battery. Then do a restart and see if it makes any difference.

Hi mate,
I was in the same boat on Monday with a faulty device that overheating and kept freezing.
What I found was I had a weird bug, and 'Mediaserver' was constantly the biggest battery drain.
So saying that, when you go to your battery stats, what is your phone telling you is the main culprit?

Try this: charge your device to 100% restart it and then unplug the charger.

Hello,
The main battery consumer when looking at the battery stats is Android System.

Take a look at this

After a couple days of owning the S7, I checked battery usage of apps
OM Customise = 10%
KNOX = 10%
I've installed Package Disabler Pro, and disabled both the above, charging the phone now and will see if it makes any difference
If the above is true, that should give me 20% back by the end of the day

Battery drain

Hello,
I don't know what can I do. I must charge the battery 2 times a day. With custom ROM and Kernel ,also in stock unrooted and with locked bootloader. It's not normal, I think. Has anyone the same Problem? Maybe the battery is damaged. What do you think?

I think it's damaged .The second charge today.

Mine is very similar. I think our batteries are gone. I am about to do a factory reset and reinstall my ROM to see if it makes any difference to battery load.

Did you try to go back to Lollipop 5.1.1 firmware .264? Works miracles for me... as I have >6h SoT (screen-on-time) on Lollipop, but <4h SoT on Marshmallow
/PS: In my use case anyway, yours might vary, yet I believe you'll see a longer lasting battery

Same problem for me until yesterday. After repair with Sony Bridge for Mac and installing only important apps it is ok.
I can not add screenshots. BetterBatteryStats says 2,8%/h. 73% Deep Sleep. Usage: 1d 5h 12 min. Now 15 % Battery remaining.

I start from beginning and the what happens.

First try to see what apps run in the background, maybe there are some services draining your battery. Is Mobile Radio Active draining the battery? If not than 100% that your battery needs to be replaced.

Try Nova Battery Tester (look for apk) set to long test and see what capacity it measures.

If your SOT run time is normal, the battery is most likely ok.
There are edits you can do if rooted but that's beyond my knowledge as to where/how to access them.
Otherwise try a battery calibration by charging to 100%, run until low battery shutdown, repeat.

Use the battery voltage to estimate the charge state of the battery.
If all that's wrong is a misreading you could just adapt to it.
You can try a hard reset (simulates pulling battery) and clearing the system cache but I doubt that will help. Worth a try.

It simulates pulling the battery and doesn't touch any data.
It's usually done but holding the volume control and power buttons down until it reboots on my N10+ if I recall correctly. It's hard to find this with a Google search but the instructions are out there, somewhere.
Of course if you have physical access to the battery you can simply disconnect/reconnect it.

On rooted phones there's a file edit you can do to fix that. I've seen it on XDA before. It doesn't apply to me so it was a curiosity.
Sorry I can recall the thread or file name.
Try this.
Try this Google search: fix battery percentage,xda rooted
Or something similar.
