Regarding all these battery issues...

Like most of my fellow XDAers, I've been struggling with battery management issues. What apps to install, CPU hogs and all that jazz.
However, while I've been very pleased with the battery life I was getting from my U8800, I saw several guys complaining of horrible battery performance. I thought that they were just 'doing it wrong'...
I now wonder...
Since November I started noticing strange battery issues. Very fast draining, misleading battery readouts... I wiped my device, flashed it with pretty much all roms (custom and official) available but my battery kept screwing me. And its been worse as time gone by! I now hardly get 8 hours with at most 1 hour of usage.
I'm now posting this after calibrating my battery 4 times the day before and the first time I used our today my battery life went from 100% to 82% in less than 5 minutes! CPU spy reports 85% of deep sleep. Better battery stats has hardly anything logged. I already ordered a new battery but if this keeps going on...
Thoughts?

Why did you calibrate 4 times? How did you calibrate it?
Charge it to full, calibrate battery using app/recovery/deleting batterystats.bin, leave it to totally discharge, fully charge. It is not calibrated until you go through a couple of charge/discharge cycles.

Very high battery drain when IDLE

Hello xda,
I've noticed a somewhat increase in battery drain the last couple of days. I charged it up to 100% and let it discharge overnight, a whopping 25% battery was drained in 8 hours of standby modus.
Now, I've installed BBS and I've come to the conclusion that system_server is taking up 70% battery when idle.

Now i've googled for numberous hours but can't get a real fix for this. I've already resetted it alot and I keep having this battery drain. is there anything else i can try?
Edit: Im running stock rooted with CF autoroot 4.4.2

LG G2 Drain battery too fast

Hello. I have a problem with my G2's battery. Android 5.0.2 (stock). He drain battery too fast. At 2-3min he drain 1% of battery!! I made a reset but it not help. I read about problem with battery on 5.0.2 in LG G2, but i don't know what i have to do. Please. I bought him a few days ago. PS: I Know about Pokemon Go's drain battery but this same problem is without that game. PS2: Sometimes when i not using him the battery gains a few % it's kind of weird. Now i have: On battery 5h 15m, to the end 3h 34m, used ove last 3 h: 38% and no I have 41%

Serious battery drainage

Any idea why my battery would drain about 49% overnight? I attached a screenshot of the battery usage
My battery has been crap the past 2-3 weeks. Right now, it's down to 42% in 9 hours with 53 minutes SOT while on WiFi w/o BT. I was getting 2-3x better than this until recently. No new apps installed. Could be an update, but battery stats has Android OS as the primary culprit.

Idle Battery Drain

Since I updated to Android 10 the idle battery drain on my k20 has been bad. Before Update it would drain 2-4% but after the update it drains like 10-15% overnight. But the SoT if I use is Good. Someone else's with same issue? And is there any fix to this?
