[Q] Samsung Captivate, kernels and battery drain?

Hello everyone I am new to these forums, and pretty much to the whole Android modding stuff...so I installed froyo and rooted my Captivate a few months ago, and since then I've noticed significantly more battery drain. Example, with 2.1 i would have 100% and leave it overnight and when I woke up it would be at 98% 99%, but with 2.2 when I leave it overnight it drops to around 70% in the morning. I flashed to Speedmod kernel to see what difference that would make (it claims better battery life), but the battery actually drains even more quickly anyone know what I can do to get that old slow-draining battery life back?
Thanks!

Really bad battery life

I bought the Nexus 5 on it's release and sadly the battery life has been really bad for a few days now. The phone also restarted a few times randomly while being in standby.
This is my current battery usage (I hope it's viewable):
Yesterday:
h**ps://drive.google.com/file/d/0B5TjklEnFH1Kb3F1dkswQjdiYTg/edit?usp=sharing
About 1 hour of screen on time and the battery is already down to 41%, even though I didn't do anything on the phone, except watching the battery usage. I didn't even use the phone-app and it's still listed.
Today:
h**ps://drive.google.com/file/d/0B5TjklEnFH1KWTFwbEI0amVHdmM/edit?usp=sharing
Screen on time: ~40 min
Cell standby & Wifi running: ~8.44 hours
Phone idle: 8.8 hours

I'm using stock Android (rooted), a factory reset didn't help.
Is there a way to fix this?
Thanks in advance
Your second day seems normal. Nothing to worry about there.
The first day battery killer was the Battery stats plus app. According to your graph it started draining after you rebooted.
On a typical day for me Android system, Android OS, and Google Services all hover between 12-6%
You can try loading a custom kernel and tweaking the CPU settings, you can load the app Greenify

[Q] Is this drain even normal?

So since I installed CM 12 then to 12.1 I have an extrange battery drain that I just can't figure out what is causing it, so I checked on Gsam and it showed that around a 14% of the battery was used by Android OS, and I'm talking about idle drain. I just can't let the phone in idle without losing between 3-4% in less than 3hs... I just don't get it. Back when I had stock KitKat I could let the phone in idle a whole night without losing a single 1%, so I'm thinking it may be a L thing? Can anyone help me here?

[Help] Battery Drain issue in One Plus One

Hello Experts,
My Battery is draining like crazy. I tried almost everything to figure out what is the issue but could not figure out. Below are the details I gathered from the things I tried.
My battery started draining almost 30 % overnight. Initially I thought it was due to the Unofficial Marshmallow Rom, I could see Wi-Fi to be cause of this drain. Hence I tried different Roms (Cyanogen Mod, PA, DarkObas, Sultan ROM, and stock Cyanogen OS ( Past 3 versions, including latest one). but the battery drain didn't stop.
So I decided to flash PA rom again, installed OpenGapps PICO (Only Google play service nothing else). I installed CPU spy and left it over night in Airplane mode. When I checked in the morning (after 7 hours) battery drain was of 25 %. This was surprising as nothing was running on my phone and only the minimum apps were installed. At this time, CPU spy showed no abnormal wake locks and was in Deep Sleep for almost 93% of the total time. The stock battery usage showed only Mobile Stand by and usage of 50 mAh.
Can you please help me figure out what is causing the battery drain.

Massive Battery Drain even when powered off

For the past few weeks, I've been having massive problems with the battery life of the phone (XT1955-4 RETEU2).
At first the battery would last for 3-4 days (Stock firmware Android 9 February patch) but now it will only last for about 12h, draining about 8% per hour, no matter if I use the phone or just let it sit.
Accubattery reports a deep sleep of ~90% while the screen is off.
Even if I turn the phone completely off it will lose about 5% per hour.
When I turn the phone off in the evening with 40% left, it'll be completely depleted in the morning with the battery LED lighting up when I plug it in.
At first I was on stock, then I unlocked the bootloader, hard bricked it first, successfully followed the guide by sluggedlemon (https://forum.xda-developers.com/g7-power/how-to/guide-recovering-hard-brick-t3989753) and then I checked out some of the custom ROMs.
Later I returned to stock and flashed OCEAN_RETEU_PPOS29.114-134-13_cid50 from lolinet.
Since then the battery life is disastrous.
I flashed the stock firmware again using the LSMA but that would'nt solve the high battery drain issue.
Then I tried to revert to OCEAN_RETEU_PPOS29.114-134-10 (February patch) but that wouldn't help either. (bootloader and modem couldn't be reverted)
All custom ROMs I tried seem to have the same problem now.
As I read similar posts about battery life issues after the April patch, I hoped that the Android 10 patch would fix it.
But even as the Android 10 update arrived and the June update soon after, nothing has changed for the better.
Is anyone experiencing something similar? Especially the battery drain when the phone is powered off?
Or has anyone an idea what could cause this issue?
Any help, advise or idea would be highly appreciated.

If it drains when it is off sounds like ur battery needs to be replaced I have a phone that dose that
It looks like there's something wrong with your battery. Maybe you should replace it.
My battery only drains a lot when the device is on standby. To avoid this I use the Naptime app. It helps a lot, you should try it too
