Really Irritating Battery drain/percentage "jump"

Ever since I have flashed 4ext recovery My battery jumps percentages. For example: If i charge my phone from ~30% overnight with the device switched on, as soon as I unplug my phone it's fine, but after about 15 minutes the battery plummets to about 90% without me even using it! Second thing, if I decide to reboot into recovery to flash a theme or mod or whatever the percentage when in recovery mode shows that it is higher than what is indicated when fully turned on?? And once again, if i reboot from there, when the device has turned on the battery has plummeted even further to 50%! Yes I've deleted batterystats.bin and calibrated the battery, and yet still this happens!
I experienced a very similar issue with my last phone (HTC Desire) and that was linked to it being "USB bricked" and was able to resolve my problem.
Thank you all in advance

Wel with my experience (do you have a percentage mod installed?) uot kitchen mods react weird with my device. The battery isn't necessarily draining. The mod isn't representing the actual percentage.
My work.around was as follows
Drain to 2 percent
Turn phone off and charge over night
(this way the battery decides when its full)
Deal with percentage reading being way off for a whole day. When it dies turn it back on and there will be the residual percentage that was skipped over. Let that drain down. Then try and turn it back on (repeat steps)
After phone dies completely then charge once again overnight with phone Off.
Wake up unplug phone, boot into recovery, plug phone back in, wipe dalvik/cache then bat stats. Reboot and unplug.
That's what I do. Sounds like a lot but you get a routine after a while. Ya a lot if people percentage mods do that to me.
Hope this helped
Good luck
I'm mobile right now

I have the same problem with one diference, when battery jump - phone turn off

[GUIDE] Calibrating Battery (Battery Wipe)

INTRODUCTION
This thread will be drawn (and the eventual new) ways to perform the so-called "Wipe Battery" or the procedure by which we calibrate the battery of our beloved Android ...
Wipe The Battery does is delete the file "batterystats.bin" which is established among / data / system / .... This file contains all the information "vital" and essential for your battery such as charging the maximum and minimum voltage, the charging time and other info ... this file after it was deleted by this procedure, will be recreated by the system properly ....
WHEN MUST CALIBRATE OUR BATTERY?
1) Always after installing a cooked rom or after the flash of an unofficial firmware.
2) If, after uploading, maybe for a whole night (being disconnected from the charger) our device, we find ourselves with a & abnormal, such as just 99% or so ...
3) If you disconnect the charger from our% battery drops quickly even in standby mode (make sure however that this is due to other causes such .. so many app / widgets running in the background without stopping)
VARIOUS METHODS
- Method 1 -
1. Take the phone to fully discharge.
2. Try to restart, if this happens, do it again to shut down for lack of battery.
3. Load the phone from off preferably a whole night or in any case a long period.
4. Turn on the phone with the charger plugged in and then peel it off.
N.B.Non requires the Root.
- METHOD 2 -
1. Completely drain the phone.
2. Get into recovery mode (if you can not do for lack of battery, connect the phone to the charger).
3. Follow the path to Advanced -> Wipe battery stats and confirm.
4. Go back and restart (or follow the path Go Back -> Reboot system now).
5. Allow to fully charge the phone up to 100% (preferably overnight or at least a long period) and then fully discharge it until it shuts off., Without connecting it to the PC to its charger during this period.
NBBisogna ClockworkMod recovery & Root have installed.
- METHOD 3 -
1. Charge the phone to 100% (with the phone turned on) preferably overnight or at least a long period.
2. Leave the phone connected to the charger and turn it off.
3. Let it load again for 10/15 minutes (again without disconnecting from the charger) in practice you will see the full charge or written% to 100%.
4. Entering Recovery Mode (always without disconnecting from the charger) and follow the path Advanced -> Wipe battery stats and confirm.
5. Restart (or follow the path Go Back -> Reboot system now).
6. Wait until the entire system is charged, then unplug it from the charger.
NBBisogna ClockworkMod recovery & Root have installed.
- Method 4 -
1. Download the app from the market called battery calibration
2. Charge your phone turned on preferably overnight or at least a long period.
3. When the phone is fully charged and then to 100%, unplug, open the program and click Battery Calibration.
4. Now you can disconnect the phone.
5. And 'suggested by the creator of the app (but not necessary) to leave the phone will download after recalibrating the battery, then just leave it off and recharge it fully up to 100% with no breaks ...
N.B.Bisogna have permission to install Root.
- METHOD 5 -
1. Turn off the phone.
2. To fully charge the phone, preferably a whole night or in any case a long period.
3. When the battery is fully charged and scored 100% unplug your phone and remove the battery.
4. Wait for 90 seconds exactly (really must be precise, wait exactly 90 seconds.)
6. Replace the battery and turn the phone.
NBNon are required they will ClockworkMod Root recovery.
- METHOD 6 -
1. Charge the phone from off to 100%.
2. When the display reads 100% off the plug and start it directly in recovery mode
3. In recovery mode follow the path Advanced -> Wipe battery stats and confirm.
4. Use the phone until it shut off by itself
5. Restart (or follow the path Go Back -> Reboot system now).
6. Upload it altogether and just use
NBBisogna ClockworkMod recovery & Root have installed.
IMPORTANT
And 'recommended (but not required) to run the Wipe Battery 2/3 times in a row, this to ensure a perfect and true calibration ...
FINAL CONSIDERATIONS
The various methods described above, are merely the result of a careful search on XDA, and consequent comments given by the various users who have tested ..
As often happens some procedures may be incorrect or not effective .. but you still leave users the right to know and taste to try .. and if you like you can bring your Feedback .. or annotations and maybe point out new ways .. which will be added with much pleasure to those already existing.
I then decided to add a poll .. where you can vote, so that we understand which of the following methods is the most used and most effective
CAUTION:
These procedures / methods are not as risky, or may cause serious damage to your device, but may still be dangerous if not done properly .....
As usual ...... we do not assume any responsibility for possible negative

Sorry to revive a 5yr old thread but I had to. What would you suggest a person to do when their phone is absolutely NOT resetting the calibration? My sons phone was saying it was at 4%. I put his battery in my phone and it said 51%. I find it very interesting that it is claimed that clearing battery stats will do nothing when there is a 50% discrepancy in the battery from phone to phone. On a 100% charge, his phone lasts less than 6 hours with bare minimal usage. (I.E. turning it on long enough to check the time and such non draining functions.) The phone is doing this with 2 batteries. It simply is NOT calibrating them properly which I would say would debunk the debunkers claims. Before you say it may be the batteries, No. I have used both of them in my phone, both last me a little over a day from 100% charge and I actually use mine as a mobile hotspot as well as various drain causing functions. Swap it into his phone, less than 6 hours and phone says 2%. The batteries are both brand new with less than 2 weeks usage on them. I believe I would go with the battery stats wipe than put up with this broken calibration garbage or some person claiming he debunked this so called myth.

Well, it won't help. Unless your son use the phone for gaming (that would drain in <4 hrs) the phone is broken. I would RMA it ASAP.

Moto Maxx never going below 15% battery

My Moto Maxx is never going below 15% battery for quite some time.
I was running CM 12.1 before and I am running the CM 13.0 preview now.
The problem now seems much worse.
This could be my battery dying?

Wait its not going below 15% or above 15%? Also, did you flash the ROM with a clean wipe (no dirty flash)?
Another thing to note is that the CM 13.0 Build is a "PREVIEW" which means that there are a TON of bugs in there. I would advise you go back to CM 12.1 for the time being.

It is never going below 15%.
On CM12.1 it also happened.
When it reaches 15% percent, the phone shuts down and needs to be charged.
After sometime charging, it displays the battery as above 15% and I can turn it on again.

Mine had always done that at 5 percent. Here lately it's closer to 7 percent.

I'm on original 5.0.2 and also facing that issue... I've heard onde it's related to the use of non original chargers, or even QI chargers... Never got rid of it, even after a full wipe/factory reset...

I've had this problem too and made a post over in the Droid Turbo forums but no one ever replied..
At least I'm not the only one that has this problem.

Yeah I've always had this issue between 5-8% on my three Turbos. Stock Rom and other flavors. They all shut the phone down around there.

Solved the problem with this app: https://play.google.com/store/apps/details?id=com.newagetools.batdoc&hl=pt_BR
Now my battery goes down to 1% again, yahoo!!!!

how can that app fix it?? i would think its a placebo effect as i see dificult for an app to read or fix battery info...
maybe it locks out the bad parts (like an old chkdsk on a HD)
anyway i will tryit if i see it tries to go rogue with the Ads it Dies..

Batteries in laptops and phones have a file that keeps track of battery life. They use this to estimate percentage.

still having this issue

I have the same problem. It started as shutting down at %5, then %7, now it's %15 shuts down.

The same thing on my XT1254. It shuts down near 5%, I will try to charge it with my old i9505 charger, it could be a problem related to TurboCharger.

Hello guys,
My girlfriend's phone had this issue some months ago, what I did in order to fix this issue was:
1) Let the battery drain until phone shutdown. (try to turn on again until you cannot)
2) Fully charge with an original Motorola charger (phone turned off)
3) When it reached 100%, turn on the phone but enter in the fastboot mode and wipe caches
4) Uses the phone normally and let reaches 0%.
Making these steps, the battery back to have a "normal" behaviour

I´ll perform these steps, thank you

Although you see the battery as percentage, the operating system does not see it that way. It uses lower limit voltage of the battery to shut down the device in order to extend battery life. Batteries do not like to get and stay deep discharged (below low level voltage)...if you do this frequently, you will severely hamper your battery's life.

Can't calibrate new battery

Hello.
Recently (~one+ month ago), I replaced the battery of my OnePlus.
The problem is that I can not find any way to calibrate it. I have tried the "manual method" (fully drain then charge, then fully drain again and charge again e.t.c.) many times. I even tried to use some applications (that I really do not trust them for their reliability, but...).
Today, I have found some time and reinstalled the phone's OS (I am using Ressurection Remix - latest build). Nothing changed.
Here's the problem, with some concepts as examples:
I charge the battery until it gets to 100%. I use the phone for example till it gets to 60% (the drain is NOT quick. It needs some time till I get to that point). Then, if I restart the phone two (2) times, I get again 95-99% of battery. Then again, I use the phone till it gets to, for example, 40%. I twice reboot it again. ~90±%! If I do not reboot it twice, the battery indicator will not change. Or it will just lose 1% percent (for example, if I reboot one time when the phone is at 60%, I may get 59% when the phone will power up).
I charge the phone until it gets to 100%. I let the phone drain out the whole battery (0%). I boot it up again. No, the battery is still alive and it may give me around 70-90% (I am not so sure about those numbers, but the idea is that the phone can still operate - there is enough juice for the phone to work).
Any ideas? I really do not know what else to try.
Thanks in advance.

All generic batteries have these issues.So far,there's no perfect replacement to be found for battery.Visit Battery Thread in General section for more information.

try to flash CM 13.1.2 from BRT (Bacon root toolkit). it should work..

Poco f2 pro charge only to 89%

Hello guys,i bought poco f2 pro global a week ago.My problem is the follow:
When i put my phone for charging the process go to 89% and freeze there.if i disconnect and connect again the charger then its make it 100%!?u can wait 5 h but no more than 89%.
Its very anoyning ,coz when i got to bed i put the phone on charge and at the morning i get it on 89%.
Factory reset didn't solve it.Any ideas?thx

Try draining the battery to 0%, then let it charge uninterrupted and see if that helps..

Hi if you've seen some of my posts. I got a Poco F2 Pro and on the second day it started showing 1% battery charge all the time. As well as an overheating issue and would close the camera after 5 seconds. Not sure what I did other than turned it off and let it charge a few times. For no known reason it started working fine. That was a week ago, so haven't had the problem occur since.
I'd check while the phone is off what the battery level shows as. If it still shows 89% it might be more serious, otherwise could be a bug

ITs not uncommon a miss-calibrated battery. Make a full discharge, wait all the time until your phone is power off. Once completely drained, try (without charger) power on some times, to be completely sure is totally death. Now, make a complete Full cicle. This time, the phone should reach 100%

Thank you all for the suggestions. I discharged the battery to 0 %,then plug it again and the result was 92%.So no luck..I really hope that this is software bug and will be fixed with miui 12 .Will be very unlucky if my unit is defective.the phone is a week old .what do you think,if i download the present software and flash it , maybe that's will help?

This so called "calibration of the battery" is total BS.
At every boot with at least the latest 4 Android versions it will "calibrate" itself and nothing one can do about it to "trigger calibration" or that kind of stuff.
When the battery won't charge beyond 89% something else is causing it, faulty battery or software related.
Did you unlock your device or is it still locked?
When locked try to manually download the whole rom new from the update menu and reflash it.
Then check if it charges correct of not.

Some devices that I have seen with the same behavior would not think the same as you, obviously with a healthy battery. A bad battery can behave abnormally too, but I doubt that is the case.
And yes, it can be called a ... "calibration", although nothing to do with the supposed magic cures of deleting the battery statistics file. What happens is not that % battery is lost or that the battery is not fully charged. In fact, if the battery is fully charged, it is the count that fails. This is perfectly evident, when the phone reaches 1% it stays in that% much longer than usual, because the phone really did not have 78% (for example) and is not full drained yet. Once the battery is completely drained, the margins are recalculated correctly again. It is not a bad battery that is not fully charged, it is fully charged, what happens is that the battery reports incorrect data due to a "calibration" mismatch.
In any case, the partner will be able to tell us perfectly if it worked, or not . I repeat, there are many phones that I have seen with this behavior and many that have returned to their being. It is clear that if the battery is bad it will continue to be bad. It has happened to me in the past with a pair of Xiaomi phones, the last one a Redmi 6, is not uncommon

Hi
Sorry , i don't have anything intelligent to say about battery calibration (except that if the battery sound faulty, take advantage of the phone warranty while you can!)
So... I just saw @Snah001 had a F2 pro and a Mi 9T pro... Could you please give us your quick opinion and advice here ? https://forum.xda-developers.com/poco-f2-pro/help/poco-f2-pro-t4137287
Thanks so much
Cheers !
