Best way to calibrate battery

Everytime I reboot my phone my battery drops a significant amount. I tried charging it in full, unplugging it, & doing it again & then wipe battery stats but its still the same. Anything else I could do?

There are different theories/methods for this. I charge to full, unplug, wipe battery stats, plug in and charge to full again, wipe stats then let it run down to about 15% and recharge and wipe one last time. People will say my way is crap but it seems to help. Also, just letting the battery run down and charging back up seem to condition the battery to your new setup. There are several little tweaks made by devs in pursuit of better battery life so it may read inaccurately at first. Let your battery settle in. I say in a day or two, you will see improvement

Dunno about the "best way", but this is a convenient way without having to boot into CWM.

Battery percentage! Help please

I'm experiencing a weird error... the battery percentage has been shown wrong.. I'm using chobits 1.8+ merruk pre 2.0...the performance is good but even weird thing is that I had 43% battery once , rebooted the phone to get 65% and another reboot it shows 90% now once I had 3% battery which lasted for an hour..
I did calibrate my battery but am still getting this issue.. Any assistance could be appreciated..

Just use right method
Fully drain ur battery
(make sure phone boots and then swich off Do that 2 - 3 times to sure)
Then charge ur battery 100% in swich off mode
Dont remove ur charger
And wipe battery status via cwm
Boot ur phone and charge 100% and done

[Q] Arc S battery issue

I have Arc S and I have used Arconium ICS 4.0, 2 months ago without any problems for while.
Now after 2 months without using phone at all I decide to charge phone and when it was fully charged I did factory reset.
After factory reset phone shows 100% battery and after some use (10-20 min) it drops directly to 0% and shutdown. When I connect to charger it goes directly to 100% and works while (10-20 min) and goes again directly to 0% and shutdown.
I tested stock 2.3.4 and some other customs roms (ICS ones), all does same. I never flashed 2.3.2 that might cause 0% issue.
So, is this still 0% issue or might it be just bad battery?

Been monitoring battery with Fuel Gauge fix apk without 0% patches to kernel and it shows battery drains normaly but phone just stick in 100%.

[Q] [HELP] [SOLVED]calibrate battery stats

somebody help me., my battery percentage still on 99%.,
how I can calibrate my battery stats, cuz in CWM doesn't have wipe battery stats., Please.

Re: [Q] [HELP] calibrate battery stats
It is definitely normal, no need to wipe stats. When a battery is full (when it is ON) it will reach 100% (but not so sure since my battery health isn't that good) but if you charge it when it is OFF and you turn it on you will get it at 99%, Always.
Also, no need to wipe battery stats. It is useless. Battery Stats will wipe itself after full-charge.
Calibrate? Don't think so..

Check if the battery decreasing or not in other apps / just go to setting > battery. If it's decreasing in there that means something has missing in your system UI.
For the easy fix just install some new theme and you will be good to go

Noob question. Help! Battery drain fast.

Hi, this is a probably already answered. I am new with root and flashing rom. After i rooted my galaxy note 2 N7105 and using jedi x16 rom. Start to drain my battery fast. I already read many post about cpu governor and tweaks. I tried different governor but it has no help. Still my battery drain fast. Any suggestion why i encounter this battery drain? Sorry for my bad english.
Thanks!

My advice, better stay close to ROMS close to stock. Plus, turn off sync, google back up, motion if you don't use/need any of those features. And explore the settings, there are things that you can turn on/off to save your battery.

Thanks!another question. Is it true that i need to wait a couple of days to so that my noye 2 can adjust to the new rom? Because. I rooted and flash jedi x16 last thursday only.

Since it is recommended by the devs, yes.
Also try charging your phone til 100% then wait for a half an hour at least then unplug it, then go to recovery mode(CWM recovery) and under advance, wipe battery stats.
And you can try DisableService app from playstore, it can disable unnecessary services of any app. Less services running, less battery drain. Be careful though with what services you disable. Here's the link for the app https://play.google.com/store/apps/details?id=cn.wq.disableservice

Okay i will try that. Thanks! By the way i have 2 diffent battery. Do i need to charge 100% and go to recovey mode? I think this is a noob question. XD
Thanks for your reply sir.

Yes charge it until 100% and wait for it to charge a little more, at least half an hour. Cause sometimes 100% isn't really 100%, that's why this procedure is needed for the phone to know what's really a 100% charge. It's like a calibration. I think you can do it only on one battery since every battery is not exactly the same.

Are you using a white theme on your rom? Better change it to black or stock theme. White colors makes the pixel on your screen light up and drain battery.

Install battery calibration by nema from the play store. It will do the same job.

No offense but you know, I used to do all this battery stat wipe stuff. Calib...etc. Then I started seeing articles about battery crash and low burn in. On top of that I read increasingly more about how chain fire himself said wiping battery stats is placebo if you think it is healthy or has any positive effect ...I really wanted not to believe it. Lol but hey that was couple years or so ago. I Dont mess with the stats unless I'm testing my work.
