Hi all, I am facing battery issue in RN5pro after flashing MIUI 11 rom. Battery percentage is alwqys showing 50%.
When phone is put on charge after turning off,it shows correct battery percentage. But after turning it on, its showing 50% battery.
I tried battery calibration using app also, but no luck. Anyone aware of this issue?
If you dont care about warranty and have a proper tools and experience, you could try to physically open your phone back-cover and proceed to disconnect the battery from the motherboard and drain all the parasitic current. After that, connect the battery again and you should be getting a proper battery reading. However, if it began to give false reading after no more than 10 charging cycles, most probably your battery are going to fail and its best to just replace it with a new one.

Hello,
My desire, after:
an inability to restore nandroid backup
a possible corrupted sd card
a usb brick and inability to mount some nand partitions
and finally succeeding in fixing it, now using/running:
2.29.405.5 stock rooted rom
a new sd card (samsung 16GB class 6)
clockworkmod 2.5.0.7
s-off
seems that has battery issues. When it reaches below 30%, it drains a lot faster. In example few minutes ago, the battery was below 30% level and after sending a couple of sms messages the phone, without the "Connect the charger" indication shut down. Not even the battery icon was red.
What should I do?
After flashing the above ROM I ran an app called battery calibration (could this be the culprit?).
I haven't experienced such problems before the whole mess mentioned above.
Thank you for your time.
Well, it seems to me like a "classic" battery meter calibration issue.

In order to calibrate the battery meter - FYI the battery itself cannot be calibrated, as Li-Ion batteries have a very low memory compared to old Ni-Cd etc. batteries - you have to go through the following procedure:
1) charge the battery to 100%;
2) let the battery discharge until the phone shuts itself down;
3) plug the wall charger into the phone, boot the phone up then charge the battery to 100% without interruptions.
If the above procedure does not yield the expected results, you can try fully charging the phone (LED showing green) with it completely turned off (after completely draining it). Again, the charging procedure should not be interrupted.
Source: personal experience - had to do this twice after installing new ROMs, as the phone was shutting down at ~14% (working like a charm now).
Regarding the matter of battery wear because of complete discharges, Li-Ion batteries do indeed have a lower cycle count than old-school batteries, but the standard charge/discharge number a Li-Ion battery can take is ~350, so you can't damage the battery pack by doing a full cycle per month (required to keep the battery meter accurate).
Good luck!

Did this work you mate? I have the same issue with my year old batter now... the phone shuts down @ 40% without any warning... and when I charge it, it starts from 0% and as soon as it hits the 58% mark, it jumps to 100% by itself... and i cant seem to figure out what the hell could I do to fix it... I tried calibrating the battery using the awesome method described here http://forum.cyanogenmod.com/topic/11823-battery-calibration-thread 3 times and nothing changed...
bump bump.. i really need help on this guys... :/

Weird that after calibration you still get that kind of issues, does this only happen on your current ROM? I have the latest CM in my desire and everything works just fine... Maybe try another ROM if calibration doesn't work to see if it's a hardware or software issue
i actually had issues with MIUI first.. the phone randomly shut down by itself but when i turned it back on, it was perfect... then i switched back to Oxygen and while everything was fine, suddenly one day the phone died at 40% :S and from that day on the phone charges to 58% and then instantly jumps to 100%... and as soon as it gets to 40% it shuts down itself... i guess i need a new battery but i wanted to see wether i can fix this one somehow so i can use it till the new one arrives...

phone turning off at 20% is fine mate because thats the battery guards against any damage
most of the phones ( smart phones) switch off at 20% as going lower can damage the System .
It shouldnt normally..It's supposed to work fine upto 5%
Have a look at this, it worked for me (but you need a compatible kernel, most AOSP are so)

The battery indicator on my brand new S3 SGH-I747 seems to be displaying the wrong amount of battery life remaining. Each time it hits around 40% the phone dies (no low bat warning) screen just flickers and shuts off. When you plug it in and turn it back on the battery life is at 0%.
After charging and using the phone for a bit I've noticed that if the battery indicator shows say 90% and you pull the battery and put it back in right away, it will drop by like 20%, presumably displaying the actual battery life left.
I've already replaced the battery with a brand new one, after that didn't help I tried flashing it with a few different ROMs none of which seem to solve this issue. Has anyone else had this problem or have any idea what might be causing it?
Appreciate any advice I can get on this, thanks!
Ps. I've cracked the screen a little so the warranty is void and I can't just get a replacement but I was having the issue before the screen cracked.

Try downloading BatteryCalibration from the Google Play Store and following the instructions to reset the calibration.

You could also try wiping the battery stats in recovery, thus resetting the battery readings.
I'm assuming one of their responses helped out? I ask because I am having the exact same same issue.
Hi everyone.
Just to write a solution for the commonly problem on the battery of this tablet; I had the problem that battery ran out almost on 1 or 2 hours! of use after it turned off I turned on again and the gauge showed for example 30% or some cases 40% of battery I was crazy about that and had to do some research; tried to bring the tablet to warranty but they did not could help me (I don't know why) after that I read there were more users having this problem; some of them suggested to bring the tablet to a repair center or open the tablet and do some technical reparation; the solution is pretty simple that it seems to me; my solution was to open the tablet with a spudger (I don't have one so I made one by sanding a piece of plastic) after that just unplugged the battery conector and reconnected it again; rebooted if recovery mode and erased batterystats.bin, turned off and charged until 100%.
At this point I have been using the tablet by 3 days and the gauge seems to show a more precise battery percentage.
Anybody that is having battery problem, and have checked that a app is not causing the battery drain, should try the battery calibration method below, before opening their tab
Try apps like watchdog or an wakelock checker app, also any apps like alarms and weather check apps or any apps that sync the tab can keep the tab from going to sleep.
On my tab s 10.5 i only charge to 70% and never unless i am doing a calibrate drop below 20%, I use my tab for video, ebook and internet.
I use an app like Gsam to sound an alarm at 20% and 70% when charging, and i dont charge to 100% as it can cause cumulative damage to the battery, check the link below for more info on how to care for lithium based battery`s

Below are a few screenshots from my tab s 10.5 , It has been running continuously for 142d without restart and i have a battery life of 3d21h according to Gsam app.

You can calibrate the battery like this before you decide to buy a new one
Fully charge the battery with the phone on and when the phone is fully charged, unplug the charger and turn it off.
When your phone is off, plug it into the charger and let it charge to 100% again. The green LED light will indicate when this is don
Next unplug the charger, turn on your phone and set the option to ensure that your screen doesn’t turn off, if you have this option. Then reconnect to the charger and wait for it to charge again to 100%.
Once charged to 100%, unplug the charger again and do not charge until the smartphone turns itself off after reaching a 0% battery level. Once off, fully charge it again and it should work properly. The screen setting can put back to normal again (meaning turn off after a certain amount of time).
phones with oled displays should not show static images for a long time as it can cause burn-in

I might have to give this a try. Like my battery has no problems with its connectors or anything since I have never had that problem. Recently, every time I charge my device, when it charges up to 97%, it immediately jumps to 100%. Rebooting still shows 100%. So when I turn off the device and charge it while it's off, it shows its at 98%. So I know it's an calibration problem. This only happens when charging up to 97%. So I might need to recalibrate again.

You should not discharge to 0% too often, as it can causes curative damage and the battery could actually fail, you would not want that to happen if you are out of warranty, I rarely discharge below 20%, a couple of % inaccuracy is not a problem really.

I hardly ever discharge to 0%, I usually charge it when it tells me my battery is low (20-15%). Well, I bought this tablet in July so I have reached probably 300+ charge cycles. I read some threads regarding battery skiping and it happens when either it's uncalibrated, or battery is slowly going bad, and something else I forget. But thanks for the tips on the battery stuff! I never knew charing and discharging fully could do such a thing!

I bought my device from Kuwait so it's firmware belong to united Arab of imarats.
At the beginning , I faced some issues with my device such as. After about 3 weeks I found the the battery stay only for 10 minutes even if it charged to 100%
I had to put my device in charge all the time so I can use it.
I send it to repair center and told them that I need to replace my battery.
After one day they call me and told me that it just asoftware problem and we solve it.
I got it from them use it for just 3 days and found anew problem that the home,back and multitask buttons dosen't work very well . That I need to but it on it's back or use the desktop cover to make it work.
In that point I tried another country firmware with kitkat 4.4.2 and that dosent solve anything
And when I found that the lolipop came to galaxy tab s with France and Canada and sanghfore , I installed it
I found that when I connect the wall charger , the device immediately turn off and give me the sign of battery with out any process in charging and dosent want to turn on.
And when the device work , it give me ablack screen when I shake it between my hand or but it on it's back (such like ablack screen flashing)
I don't know what to do.

i have a samsung galaxy s6 edge
Hi! My old battery was inefficient (45% health at AccuBattery) and it swelled so I decided to replace that one. Everything goes easy because it wasn't my first battery replacement in this phone but just after replacement I noticed that the new battery is draining fast also. I was operating on MIUI 12 by Xiaomi.eu, so I decided to rollback to Stock ROM with MIUI 11. I flashed it with MiFlasher (With full wipe). But still new battery was draining fast (51% health) in AccuBattery. Then I want to make sure if this new battery is actually new, so I bought another battery, but this time from other company with good rating and replace it. And this do nothing because the newest battery phone is using only with around 50%. I tried to recalibrate battery once, I drain phone to 0%. And then I want to charge it to 100% without turning it on, but it turns on automatically and it gives no effect.
What should I do now?
Only one right way is to measure battery capacity with special charger. Something like this.
Drain battery to 0%, turn phone off, connect through device, and charge to 100%.
