Hi guys, today i was charging my Redmi Note 9 Pro and I observed that it stopped on 86% (it said charging) and waited for like 2-3 minutes and it didn't change, and I read about battery calibration so I downloaded first app in google play and calibrated it (with root, I have magisk), now it charges normally.I also read that I need to wait for 2-3 weeks to see the battery working properly. Is it ok if I calibrated it from 82% ? Or is it better to calibrate it manually without any apps?
Now my battery discharges faster than before, I mean not from 100% to 50% in 10 minutes but a bit faster discharging
P.S read this post https://forum.xda-developers.com/t/xiaomi-redmi-note-9-pro-question.4329433/ that I did from my second account (read Question 1) in it I said that I flashed stock miui rom maybe this is the problem (incorrect battery status)

Hi there!
Since I updated from CM 10.2 to CM 11, I've been having battery drain issues with my S3. It drains really quickly, and won't last me through the day most of the time. Today I unplugged the phone at 6AM, and by 2:30PM, the battery level was at 10%. It was after 2PM that it started losing like 1% of battery every minute or so (even when not in use!) so I switched to airplane mode in order for the battery to last until I got home. Also note that I only used the phone for a while today (1hr 23 mins - see battery stats) and the usage was light - 20 mins music playback, one Bluetooth transfer, 15 mins WiFi tethering, 5 mins Hill Climb Racing - these are the most 'demanding' things I did with the phone. What really shocked me was that around 2PM, my friend's Huawei phone was at 60%, while mine was at 20%, but he'd had 2.5 hrs of screen time while I only had 1 hour. Not to mention his phone is more powerful and has a better screen...
I have Location set to Battery saving mode and have Location Reporting & History as well as the hotword recognition thingy turned off.
I've been on CM 11 since January, and recently updated my phone from M2 snapshot to the M3 version. While updating, I wiped the cache, dalvik cache and wiped all user data, thinking it would fix the battery drain. It didn't. Back on the M2 snapshot I tried greenifying Facebook, Messenger, Google+ and WhatsApp, but that also didn't solve the problem.
Also, about a month ago, I bought a new (original) charger for the phone, because the old one wouldn't charge the S3 when in use and when not in use, it would charge really slowly (like only 70% overnight in a few cases). The new charger fixed those issues, but could the battery drain be connected with the charger issue? Could the battery be damaged or dead? Or do you think it's a CM/Android issue?
I'll probably try to buy a new original battery, but I wanted to discuss this as a new battery might not fix it.
Thanks!

BETTER BATTERY STATS
http://forum.xda-developers.com/showthread.php?t=2539568
I did perform a search and I know there are many threads about battery life but thought my problem was a bit different so I made a new thread. Thanks for the links, though. Even though I've already done many of the suggested tips from the guide, I switched to ART yesterday and installed Better Battery Stats.
Now, 13.5 hours since unplugged, I have 37 % of battery left with 2 hours of screen on time. I guess enabling ART might have helped a bit...
Just a question, what am I supposed to look for in Better Battery Stats? I mean, is it Kernel Wakelocks or Partial Wakelocks that drain the battery more?
Oh and btw, the second link took me to OnePowerGuard Pro not Better Battery Stats. Just saying.
Hi,
My phone battery is behaving abnormally since few days. The phone goes off at around 40% battery showing a low battery warning. It does not switch on unless I put it on charge and switch it on. After switching it on it shows random battery percentage like 23% or 71% etc. The battery is also discharging fast these days.
My OS is Miui 8.5.7.0 updated 2 or 3 weeks ago.

This could be due to faulty or a degraded battery
I have had also faced this problem on my previous devices and that was bcs of degraded battery over time
Can u tell me what's ur device age and also to make sure it's a faulty battery or something u should first take backup of everything and then clean Flash miui using Mi Flash tool
Thank you for replying. My phone is of 1 year old. I can bacup & clean flash but I have too many important things on my phone that I do not have time or I can't take risk of missing something. If I have no options then I can flash. The battery quality of Redmi is very poor, my nexus tab is running fine even after using it for 4 years and doing more recharge cycles.

hi there,
as the title says,
what i wanted to do is to drain my battery to complete zero.
my phone will die suddenly when the battery indicator shows 40%-50%.
so i think a way to fix this is to drain battery completely and charge it back up again from 0%(or at least 1%).
the battery problem happened when i moved to custom rom.
cant do the strong vibration, high acc gps, max brightness since when the battery reaches ~50%, my phone will shut down immediately.
so, is there a way to drain battery?
thanks
How to fix Xiaomi Redmi Note 3 (kenzo/kate) battery problems on Custom ROMs
Hi @dewasa98, I had these battery problems too when I switched to a custom ROM (LineageOS) some year ago. my phone was already about two years old though. the phone would shutdown at 25% or sometimes 50% of battery. it also had a weird behavior while charging, it would start charging at 25% while it has just shutdown...
I replaced my battery, and all these problems were gone! The phone feels as if it were new
My advice for you is to get a new battery and replace it yourself. it's very easy and straightforward on RM N3. Watch a video before you do it, and everything will be fine. This will extend the life of you phone two more years at least :good:
The battery reference for Redmi Note 3 is: BM46, in case you want to get a new one.
Hey OP, did you ever find a TWRP script to drain battery? That's what I'm currently looking for.
After updating 9.2.4 china stable in update app on mi pad 1 I decided to downgrade to miui 6 to get clean experience and better battery.
In mi recovery I cleared cache and then installed update.zip to system one as someone said it fixes bugs and runs new rom smooth. It indeed fixed the time taking to turn on wifi problem but battery started draining like hell(jumping from 70 to 55 to 42 etc)
Then I tried all other stock miui 7 and miui 9 but the problem now is battery INSTANTLY charges to 100 and discharges to 0.
With charging however it works normally but battery stuck at 100 and turn offs seconds after I unplug the charger
I checked battery connection is well with motherboard and its not swollen and with usb connected to pc (which charges very slowly when it was good) when I heavy use it it stays for a lot of time.
Please help me with this issue asap.
