When you recalibrate your battery, it takes a few life cycles for the battery to stabilize and for Android to get an accurate reading. First life cycle is alway short. Of course, don't play with ROMs so much it may damage your phones read only memory.
I will post my battery life soon, I'm still waiting for the battery to deplete, I haven't recharged my phone in 4 days now after I calibrated my battery.

Wow 4days is huge,iam getting hardly 1day battery after calibrating yesterday....
Actually i removed my phone before getting the 100% notification....
So should i wait for battery to improve???
By the way,when did you calibrate???
Should i calibrate again????
If this wont work i will try terminal emulator method...
So in this method do we need to charge 100% or discharge completely??
Some precautions or just write those commands at any point of charge???
Iam wondering how to thank from the xda app
Thnx to both of u

Same problem here.
Battery drained from 100% to 60% in 3 hours, then to 15% after 5 hours. phone super hot! Widget showed temp 42°C !
Not even used the phone for more than 15 min! REALLY!
Then calibrated before 3 days, now a max of 1 day battery backup only.
Plz help.
And 1 life cycle means I must let the phone charge 100% then let it discharge till it's switched off.
And I should repeat the cycle.correct me if I am wrong.
And I have the habit of not charging to 100% in a single charge session, 2-3 breaks, should I change it?
clarkkov said:
If your phone is hot without you using it, something is running in the background, that shouldn't. Which ROM are you using and which tweaks/fixes have you applied?
One battery life cycle means battery drain from 100% (fully charged) to 1% (fully discharged). Your phone does not have to turn itself off, but make sure it is at 1% when you begin to charge it again. This is important only for a few cycles after calibration, afterwards you are free to charge it as you wish, but while calibrating it's highly recommended that you don't interrupt the charging process (4Hrs).

I am using rooted jpd from samfirmware, no fixes except sdcard speed fix, previously it used to give a good battery backup.
And apps do run in background.
Should I set autokill level to high in task killer?
And I will take care of charging.
Thanks for support.
on DDJP2.. getting a horrible backup since i have updated thru KIES. generally on jg6 used to get almost 1.5 days which has come down to 12-16 hours now. trying to calibrate my battery with app 'battery calibration'.. calibrated once.. but still no change. read somewhr that we get the same backup for first few times even after calibrating.. but to get sure i am writing down my process.. plz chk if m doing right or not ..
1. plug in phone with charger
2. wait till 100%.
3. press battery calibration or delete batterystat.bin with the help of root explorer.
4. unplug charger and use it till it discharges completely.
5. charge again to 100%.
plzzzz chk and tell.
plzz someone reply.
I have a question about batery drain. Apps on backgroung are drainning lot of batery? May i have to stop them always?

Yes.
You need to be aware that wireless services are draining the battery the most. If you are not using 3G - switch it off, same with BT and WIFI. Widgets that update frequently also drain the battery fast, background data, auto sync services/features are battery killers, too.

Thanx for the reply.. i have calibrated once more.. but already showing 80% after hardly 2 hrs.. no clue whats going on... ppl with JP2 shud come up with thr battery backup to get confirmed.
and last thing am waiting for is that someone said .. battery life is worse for first few cycles after the calibration... thats the last hope... :'(

Thx for the aswer, i thought that all the background data are drain lot of battery. I'll try to calibrate and switch off all the thing i can and see if my battery lives more time
Hey there,
scince I use BatteryLeftWidget, I can see that my battery voltage only reches 4171mVolt.
So, batterystat.bin delete doesnt help, so anyone an idea where to put the 4200mV ?
This happens when battery level is below like 30% on my HTC Evo. I am using a customized ROM (Supersense). Whenever the battery reaches 30% remaining, it doesn't drop. However, if I use the phone for a while and restart it, the battery shows only 10%. Clearly, some of the battery management program does not work properly. Is it a bug related to battery itself (hardware) or ROM (software)? Anyway to fix this?
You could try charging your phone up fully then go into recovery and delete the battery stats(Under Advanced in CWM), unplug your phone and use it until it discharges fully and shuts off. Finally, recharge the phone fully again once it has died. I believe this will calibrate the software that monitors your battery or something like that. You can find more specific instructions on the net if you want. Some people like to bump charge and everything else to try to get it perfect but I never found the need to go to that extreme.

Download "battery left" from the market and it will recalibrate your battery. Also yes, I would reset battery stats as well but battery left will actually recalibrate it. Battery stats is how long the phone has been on, what's using the most battery, etc. Correct me if I'm wrong.
Just boot into recovery and wipe battery stats.
I had this problem once.
All I did was download "Battery Left" as VICODAN said and I flashed this zip that I got from somewhere on this site but I forget where. I had to change the updater-script and the binary but either way it works on our Shift. Charge to 100% and flash this, then with Battery Left install use the phone till it dies and after that, you should be golden.
battery calibration
U can try the app battery calibration also in the market. If you're rooted.
*Since we're talking about batteries.
I wish our phones would beep or set off an alarm when charged to 100%.
I was keeping battery calibration just for that, it has that option but only worked maybe 1 out of 20 times the alarm went off.

Love the app, so when i got to sleep or I am going to calibrate, I just open the calibration app throw it on charge, it beeps I hit calibrate unplug and done. That way I don't have to open the app when It's 100% or with early morning fuzzy eyes and fingers that don't work right

Wrong forum...you state that you have a Evo, this forum is for Evo Shift.

Hi, today I went to office, I can see the battery reading is 84% after one hour of use in the transportation. When I plug the phone to the charger it shows 100% immediately (Charge so quickly isn't it ? :laugh. It remains 100% even I reboot the phone. Did anyone meet this bug?
Have never encounterd such a thing. Are you rooted?
Sv: Incorrect reading for battery after updated to 4.2.2
Never seem it but try a factory reset. I always do one after a system update.

It's likely nothing is wrong. After every ROM flash, the battery calibration always messes up a bit. Just use the phone normally and the calibration will fix itself after a couple charge cycles. If you want to fix it sooner, run the battery down and charge it again.

That will happen with any/all N4's at some point. More commonly the battery will lie to you, forget to update battery level during deep sleep, etc... Your phone isn't "broken".
Mines just did that today.. Was at around 38, plugged it to the laptop to transfer stuff, took it off showed 100.. reboot fixed it but now I have to recalibrate

i tried it on my old phone and it worked. So far my N4 is still fairly calibrated.
batterystats.bin has absolutely nothing to do with the battery level your phone is showing you. Its a per charge battery history file, i.e. what you see if you go to Settings>Battery.

As far as am aware it doesn't really work? So your saying changing recovery for you helped with your battery, coz like i take it off charge and its 100% then it jumps down to 97% after a few minutes and am not even doing anything.. and i just got this phone this week. Am tempted to send it back, i don't know what to do?

That is because you left the phone plugged in for so long that it hits 100%, then it starts discharging to prevent overcharge.. so it drops to 95%, then charges again. You took it off at 97% (yes, it might still have shown 100% for a little while so you don't go and plug it in again).

So how do i charge it so it doesn't drop, i am getting severe battery drain, i take it off at 100% after checking instagram, twitter and chrome for 10 mins its dropped to 70%.. matr1x kernel with CM10.1..? thanks!
Hi everyone, i have problem with my note 4, battery drops from 11 % to 3% very fast and charges after 85% very slow.. this problems started 2 days ago when i flashed dn5 custom rom i thought it was rom problem and flashed sixperience rom but still i have same issue also i tried battery calibration but again.... what can i do???? and my screen on time is only 3 hour. please help me, thanks.
Have you checked what's eating away at your battery? Settings => Battery (Here you should be able to see if anything is causing a drain).
If the settings screen doesn't seem to show anything, you could try BetterBatteryStats (This app will be able to tell you everything that's going on regarding running processes, wakelocks,... You should give it a day or so from a fully charged battery.)
And if even BBS doesn't show anything, I'd flash the stock firmware again (And check if it isn't the battery).

Well, in all fairness, mine is running CM 12.1, and SOT is a bit under 4hrs. Which isn't fantastic either. Quickcharge does slow down a bit after a certain percentage. You could try a new battery, but might be a waste of money.
I'm afraid I can't help you any further, maybe someone else can.

did u change ur battey? im going to buy anker battery as i know they have good ones
I am facing exactly the same problem .. I don't think buying a new battery will solve this problem.
My mobile is charging by AC very very slow and sometimes it stuck at certain percentage for hours and I tried many things but I am still facing this problem... While recharging if I removed the battery and put it again, the phone shows me that it is 100% while it was not 100% at all.
I wish someone can help us about this problem or if any of u guys tried a new battery and the problem has been solved, so please feed us back in here
Any updates!?

well after 3 4 days (i mean after flashing sixperience rom) everything is ok. discharge to 0% then wait and full charge + calibrate battery may fix issue. but still dont like screen on time. only up to 3.5 4 hours
That sounds weard...
I mean the good thing is we could change the battery.
I have a feeling this is not battery issue. it's exynos + apps running on the background. Try to root + disable unnecessary apps (maybe Android 4.4 Would give you higher SOT). I had Note 3 previously and SOT was at the level of around 6 hrs (snap processor) - now on exynos it's around 4 hrs on stock firmware (5.1.1).
Hello im using validus Oreo ROM
Almost the ROM was good
But one problem
While I switch off my mobile and charge it
After the two hour I look the phone it show me 20% battery
But I use the mobile for an hour the battery was still at 20%
I think it has incorrect battery status bug
Even I restart the mobile again again and again it show only 20%
Any alternative method?? To know my correct battery status
