TF201 Severe battery drain after KatKiss Rom install - Asus Eee Pad Transformer Prime

Hey all,
Was wondering if anyone else is getting this issue with excessive battery drain after installing KatKiss.
Before install of KatKiss Rom Nougat 7.1, my TF 201 had the stock rom 4.1 and I could leave it in standby mode for days and still have lots of power left when I decide to use it.
Now after the install of KatKiss, the battery drain is ridiculous. After a full charge this morning I decided to leave the tablet in standby and have nothing running in the background, no apps or anything. From 8am this morning till about 9pm when I checked it, it went from 100% to 56%. I didn't even touch it.
Is there something with the settings maybe I could change to help with the battery drainage issue or is it the rom itself. If it is the rom, can anyone suggest another/better one.
Thanks

I also have a battery issue with my TF201. Also have Katkiss installed, but I can't say that the software is at fault, since I did see a slight improvement on battery life while using. I
What I did notice though, is when it is on standby, it does drain faster than it usually did. Probably has to do with battery optimisation in the code?

[Q] Battery status is off

I've had my G-Tablet for over six months and its awesome. The specs are very high for a older tablet so JB Smooth Bean works great. The problem I've had since the first ROM is the battery status. It never charges to past 96%.
I've wiped everything on the tablet! Cleared the battery status in the rom, discharging the batter to 0% and then wiping the battery status in the ROM before charging!
Battery life is still 10hr so the batter holds a charge. I'm wondering if the battery is bad or is it a system issue.
It's a known issue. I haven't been able to fix it myself but then again it doesn't bother me too much. There might be a solution on the forum somewhere...

Galaxy s3 battery issue with SynergyROM.

Hello,
Originally I was running CleanROM 5.6 and felt like trying a new some. I decide to give SynergyROM r484 a chance, a while a few minor bugs bothered me, I really like the ROM. However, the battery is giving me some issues. Two nights ago after setting up r484 I let it charge overnight to 100%, when I got home the phone was at like 24% and eventually the battery went to 16%. It stayed at16% for a looooong time and then shut up. I tried charging the phone and after 4 hours it only charged to 20%. I shut it off and turned it on again after a 3 minute "break" and the battery was at 47% instead of previously at 20%. I drained the battery fully and then again charged it overnight fully to 100% while the phone was off. I was thinking maybe I fixed the issue, but right now I got home like 20 minutes ago and my battery life is decreasing at a "steady" pace but now it's stuck on 23% and has been for a little long time. I feel that my battery is probably around 15% in actuality. It seems upon installing SynergyROM r484, when the battery gets low... it doesn't display the correct percentage and I feel that's a huge issue. I'm also running leankernel 2.2 if that's an issue? I really would like to use this ROM, and while it's functional this battery issue is a serious problem and I'm thinking of flashing to CleanROM 6.0 for something more stable.
Does anyone else have this problem? I was hoping if anyone had any idea of a fix or something along those lines.
Thank you for reading,
Zealex.

[Q] Sudden battery drop

Recently, my battery percentage has been suddenly dropping like in the pictures below. It usually happens when I'm playing a game or doing some other battery intensive thing. I don't think the battery is really drained because it usually discharges to 1% and stays there for a long time in standby. But if I keep playing games, then it will shut down.
I am currently running Neutrino 3.02 and have had the same problem on CM 10.1 with the latest kernel.
I use ravilov's battery calibration app, but it doesn't seem to solve this problems. Does anyone know what the problem could be? Maybe the battery is too old or something else... Thanks for your help!

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 4 (Mido) Battery Drain

No matter which ROM I flash, my phone's battery gets depleted over the night. I can't even see what's causing the drain as by morning the phone runs out of juice and gets switched off. The phone was running fine when I was using xiaomi.eu ROM. I recall flashing the latest firmware and an AOSP based ROM; since then the phone gets way too hot and battery drain ensues.
Right now I have ArrowOS (Android 11) flashed and face the same issues. I'm thinking about downgrading to the last stable firmware that's available here (https://xiaomifirmwareupdater.com/archive/firmware/mido/) in the hope that it would solve the problem.
Is this safe? Is there any way I can solve the battery drain issue? Please help me!
P.S. My phone has stock kernel that came with the phone out of the box.

There really is no reason why this should happen on all custom ROMs.
So either your battery is dying or one of your apps is draining your battery

Try calibrating your phone's battery.
steps-
1. fully charge your phone keeping it switched off.
2. turn on phone and leave it on standby (DO NOT USE IT AT ALL)
3. after it switches off automatically, plug it in again (KEEP IT SWITCH OFF)
repeat this 2-3 times
Also, post your battery log
If this doesn't works, either your battery is faulty or its issue with motherboard

I used AccuBattery to check the health of the battery; it says almost 93% which seems unlikely because I used this phone for almost two years continuously. Surprising thing is I have a Redmi 1S as well which I bought six years ago. It keeps chugging along fine and doesn't have any battery drain issues. If it weren't for the 1 GB RAM and accompanying sluggish performance I would be still using that as my backup.
Anyway, I'm gonna do what you suggested and see if it works. How do I get the battery log?
In terms of battery life, Zeelog's Android 10 with Kernel 3.18 is the best choice, for example, I have about 1-2% loss in flight mode in 24 hours, inactive with WLAN about 3-6% in 24 hours.
Do a clean install.
