[Q] Help on the battery that is charged up to 21% and then nothing

Hello guys as the title Xoom charges the battery up to 21% and then goes directly to 100% but this is false as soon as 20 minutes of use and the device turns off. I tried several rom made ​​by your great forum but same problem is with the original 3.2 that with the other. I want to specify that the Xoom was bought in New York but is now in Italy Thanks for the help you want me

Make sure if it's a U.S. xoom you use the U.S. roms. I don't think you can flash the euro versions without issues.

This problem has always been I tried to change the rom just to see if anything was resolved, but also turned off when it does and 21% if the attack led to recharge for a few minutes and then immediately green and white and when I turn it on gives me a 100% false
But you can not charge from usb?

No the Xoom requires too much juice to be charged through usb. You must use the wall charger.

[Q] Help on the battery that is charged up to 21% and then nothing (Solved)
Ok guys problem solved. After I installed the root system calibration apk battery went all right now the tablet is charged up to 100% and the battery life of at least 4 days now and with little use. One unique thing I've noticed that when you unplug the charger for a few seconds you see the 21% and then 100%

So it sounds like you had a combination of battery in need of a fresh calibration and failure to charge due to trying to trickle charge via usb (which doesn't work). Glad it's all good now.

They are forced to use every now and then reloading the battery manager because when it stops at 21% and goes out shortly after the septum if the battery through the program to 100%

[Q] Battery problem

Hey guys I am a long time Android enthusiast. I have one of the most popular Samsung devices which is the Samsung Galaxy fit. The problem with my Samsung Galaxy Fit is the battery. Earlier before any tweaking battery used to be normal. After I installed CM7(official build). My battery started draining randomly. At first it was ignorable but then the problem became severe. From 100% it would drop to 88% in just 2 mins use and then from 88% it wud drop to 70% in another 5 mins and the entire phone would be dead in just 3 hours at best. When I would charge the phone again the battery will also be charged randomly going from 5% to 20% and then 20% to 40% all this in just 10 mins. In no less than 20 mins would my phone be 100% charged but that's fake as the battery would drain from 100% to 0% in three hours.
Following are the solutions are tried
Changed the batter,used a brand new original battery(FAIL - DID NOT WORK)
Flashed stock Rom (FAIL - PROBLEM STILL PERSISTS)
Changed Charger (FAIL)
Recharged battery on a different phone and then inserted the battery in fit (FAIL)
If anyone has any solution please let me know. I AM ALSO WILLING TO DONATE IF PROBLEM GETS SOLVED.

You could try Battery Calibrator.. The app is available on Play Store.

Hope this will help you..
1. after flashing custom ROMS, back to recovery or CWM then wipe the battery stats.
2. calibrate the battery while device is on, i ussually use Mugen Power app (install app, choose the standard battery, charge until 100% then click calibrate, after that use the device until the phone is dead then charge until 100% again while device is off).
other Calibration apps ussually have the same steps like the steps i mentioned above, so just use one app..
3. if you still having the battery drain, maybe you should go check the hardware in some technician, coz it could be the hardware that has the problems.

[Q] one mini battery level suddenly drops to 0%

My one mini will drop to 0% when I am using apps like chrome or when I am gaming. There will be a 0% battery notification before shutting down. I also cannot turn on my phone after that. It will charge to 100% normally after that. Have tried battery calibration app and some online methods but they don't work. Weirdly, after I charge my phone to like 20% after the battery dropping to 0, it will discharge normally. It would not do that after it went above 30-50%. Before the incident, I have discharged it fully a few time after gaming. What should I do?

What ROM are you using? I had the same issue on Lollipop but never on KitKat.

Sounds like you've go the same problem as all of us here:

Pixel on Android 10 doesn't fully charge when off

So I've noticed that the phone doesn't charge above approximately 73% when fully turned off. I'm using the standard Google charger for the phone. It also charges normally when the phone is turned on. See screenshot...

My refurbished Pixel also does not show only around 65% charge after being plugged in for the whole night.
But then when I use it, it sort of freezes at a specific battery percentage, so it is on for example 30% for two hours, before it goes further down. See the attached picture.
So at least in my case, the phone is fully charged when turned off and plugged in, but somehow the percentage count of the phone does not recognize it. Maybe it's more or less the same in your case?

I too am having battery issues since updating to the latest October Android 10. I have bootloader unlocked and rooted with latest magisk Canary build.
I can charge to 100% but it then tends to stick at a certain% for a while and then the battery dies at 15-20%. I've tried battery calibration but it doesn't seem to help

I've had a dose of the same lately, had a couple of days where my charge has reached 42% for the entire day? Still charges fine but from a 100% charge I will lose at least 13% - 16% charge in a few hours on idle with nothing showing as draining heavy in battery manager. If I run it down to 18% or less and try and use the camera it will shutdown and if I can get it to reboot it's on 1%. I've come to the conclusion its the battery (could be wrong) purely as it's acting exactly the same way as my nexus 6p did when it's battery started to fail.

OP7 Battery Calibration - without root

I have OnePlus 7 11.0.9.1.GM57AA, on Stock (No Root) I have recently replaced its battery, new battery is going good with decent backup, but with a trouble. It is (I suppose) wrongly calibrated.
It drains from 100% to 1% in 3-4 hours of regular use, and then remains on 1% for next approx 6+ hours, and eventually phone shuts down. I remember something similar happening with my (now vintage) nexus 4, after flashing ROM when battery wasn't sufficiently charged & then I have to re-calibrate it.
Trouble is my phone is not rooted, tried the guides given on reddit like charging it 100% while it was off, and the boot on & charge 100% further, then drain it shut down and charge again for 5 iterations & cache wipe after that. It is not working.
Any other way to calibrate battery please?
TIA

same here, found anything?
