Battery draining a lot - Galaxy S6 Q&A, Help & Troubleshooting

Put all apps on my phone, and I am getting a lot of drain recently. 1% every 7 minutes in standby, battery graph only shows screen which is 4 minutes. Had it on for an hour and it went down to 88%.
Going to do a smart switch rollback on the PC, however the software description is in a different language - does this matter?

put the Flight Mode and disable Wifi

I'm getting results similar to yours.

My drain overnight :

Also enabling Power Suspend with Hacker Kernel helps with standby battery drain.
Adding these lines to your build.prop helps too :

Battery reading issue on Skyrocket

Very weird, and this happens all the time, everyday. About once to three times per full charge since i have the phone. I restart the phone for some reason and when i get back, i instantly lose about 5 to 25% of battery.
I'm rooted on stock rom...also i'm guessing this is a calibration issue so i am fully uncharging / fully charging battery tonight to recalibrate it but in the mean time i wanted you guys to confirm if i'm right
Also if this is in fact a calibration issue, does this mean that my phone is discharging faster than it's actually telling me?
Here is a screenie
one big peak loss a few hours ago and a smaller one just now

Battery life on N5

So I have been using my N5 with average usage. I do not do crazy gaming nor do I have all types of battery saving apps. But I have noticed that the battery life is phenomenal... I don't know if the phone is misreading the battery but last night I left my phone without charging and most of yesterday without charging. I also have a cm alpha installed and lowered CPU frequency when screen is off (to 300). Here is a screenshot of the battery meter

Could this be a misread? Is there a way for me to wipe my battery stats and test then?
Thanks,
Kevin

High overnight battery drain

Losing more than 15% overnight despite having WiFI, BT, AOD turned off. It's been happening since first week of December. I ignored it at first as it wasn't that frequent and most of the time I didn't lose more than 5% overnight but these days it's just frequent although I tried factory reset, restricting apps and more but still half of the time I do lose lot of juice overnight.
I've attached screenshots of Better Battery Stats, help me figure out what's wrong ?

The "android" waking up your phone all the time seems like an obvious culprit, but that's probably just "anything that's part of the system"... Can you get more detail on that?

Android 12 has an option to stop charging at something around 85%... (to protect the battery life)... did you perhaps set that option?

Redmi note battery Drains to fast

Asking if how to fix redmi note 9s Drains battery so fast? I already tried the calibration and formatting it but the problem still occurs. Symptoms of it the phone always rebooting when I open wifi,camera and share it. When it happen the phone drains battery bit by bit and upper back of the phone heats. With 3 hours of screen time only 30% remained. Appreciate fast replies thanks.
The more apps are running ( whether in forground or in background ) the more the battery gets drained.
