RN4(Sd) Charging Time and Battery Information Problem

Hi all. I have a rn4 snapdragon (mido). I have a problem since I bought this phone. I learned that this phone's charging time should be average of 2 hours. But this is 4-6 hours for me. I think my phone's battery percentage is incorrect. Because battery percentage does't change for 1-2 hours when I take it from the charger. How can I solve this problem? Can be the charger or battery broken? (Same problem at custom and stock roms)

How to drain battery fast with flashing script in TWRP

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.

Redmi Note 9 Pro Battery problem?

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)
