[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.

Yeah I agree too..Not much difference
but still not that difficult too (Matter of seconds?)

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

Thanks for this! I heard from some android users that Battery Calibration is a myth, but it appears to be really effective anyway.

This work for me. Don't wipe battery. After install ROM, remove battery about 5 minutes and it is well.

Cell Standby Battery Drain

Has anybody else had trouble with rapid battery drain and Cell Standby being the process that's taken up most of the battery? I'm completely stock and unrooted at the moment

It's a known issue. They apparently added the wrong power draw amount when calculating the percentages so those are wrong but it's not really using more battery, just misreporting.

Do you know if this works only with a custom ROM or can I just use the non-Odin root method?

I used the non-odin route and just installed it on mine. Cell standby dropped from about 30% to only 3% after install.

So with that calculation being incorrect does that result in your battery life draining faster? I just got mine on 9/22 and battery is draining significantly due to cell standby (cell radio being at the top of the list) I heard through a friend that this will be fixed with jelly bean update?
Can anyone shed some light as I just switched over from iPhone 4 and this whole battery issue is disappointing, thanks!

Battery not draining faster. Percentage reported in stats is wrong. 30% shown is actually 3% and should be at bottom of list.

Thanks for the reply prdog..one more question cuz I just came back from the Verizon Store and they can give me a new one if I go back since I just got this on Saturday..
So the reported stats is wrong as you stated in Battery setting..so thats the reason why I see my battery level indicator draining? Because it does drain pretty fast.

Battery life very poor in nougat

battery life is very poor in the latest nougat update.. when the screen is on my battery percentage fell form 60% to 50% in just fifteen minutes... all i was doing was chatting and listening to some songs.... is it just me or the battery life is really this poor?
any way around?

factory reset your device. should sort it

Having the same problem. Latest XEF.
Factory restore did nothing to help.

Try German dbt firmware, users have reported good battery life on this version of firmware

At least I have pretty good results with nougat m .imgur. com/M5NpRFB m .imgur. com/ra2NRrE (delete space)

Battery issue

I am getting SOT of 2.5 hrs with just normal usage...dunno whats wrong

LoL how is this possible tho?wish someone has a solution for this...

120hz drains the battery soon. Set the refresh rate to 60hz if you need more battery life. This issue may be solved in any update

I've already done it,the 88% is with 60hz if i had it 120 probably it would be like 95% lol

Mine is 93% at 60Hz and I still get 10+ hours of SOT.
I highly doubt it's anything to worry about..

It just means that out of all the battery that was used up to that point 88% of the used miliamps went to the screen, which makes perfect sense since it's the heaviest battery user out of all the hardware bar the CPU.
You wouldn't want Android System to be using 88%, wouldn't you?

Well it make sense i guess...tho never had screen in first place on any android phones i had anyway if this is normal then i guess this solved my questions and my doubts

12.0.3 update has reduced screen battery consumption
SOT also increased from from 5-6 hrs to 8-10 hrs

It's a stable update. Changelog: system stability and reduced system lag
Edit: tried updating but it failed for some reason. Maybe Magisk is the reason? Idk. Checked update again and the size changed to 2.2GB

@Slim K -- I just restored from MiUi from xiaomi.eu and just saw the update! factory reset after applying the update!

Ahh, yesterday It wasnt available for me yet. Today i could update It. For sure, they have changed the way the % of battery use is calculated.

Yes, less battery drain and I've noticed that the phone seems to be faster and smoother.
