Hi experts here,
I am new i9000 user coming from G2.
I flashed XXJPK for days, found that my battery drops very fast.
I stop all data access at night and the battery still drops...
I found that the 'Display' uses > 80% !! (even when I slept for 8 hours)
Attached is the screen cap of my battery stats..
Do anyone has the same issue?
This is Android Development, not Questions & Answers! Please post in the right sections!
What have you installed after JPK? Task killer? Lag fix?
Mine is not doing that. I did a hard-reset yesterday, installed my apps (no task killer, no root, no lag fix) and disabled everything (WiFi, bluetooth, GPS, 3G, autosync). Battery did not drop even 1% in 6 hours.
Display should not take any battery if it's off. Maybe you have something that awakes the phone constantly. Check autorefresh on weather, e-mail, twitter, news feeds... I usally have that disabled or set to 8 hours minimum.
got the same problem here.. i do got the docrom (custom rom) ,auto killer installed and lagfix (OCLF v2+) it goes from 100% to about 60% in 9 houres.. without doing a thing.. on top of that i got juicedefender ultimate installed.. but it doesnt seem to help at all..
The problem is why the 'Display' uses > 80% while I off the screen for hours?
Got the same problem here. I just reverted back to jm8 (eclair 2.1) with takayuma Rom.. I think all froyo versions have battery draining issue
I think, you guys must make this and maybe fix battery issue:
Refreshing battery stats after Odin or flashing (important)
or me personal, for my Galaxy very helpfull was this HTC Desire methode:

I'm having exactly same problem with you. My brightness is 75% even in sleep mode and it drains the battery. I guess thats the main culprit to solve my battery draining issue. I wonder why it happens to certain people, because some users only have 48% for brightness and their battery can last more than a day
** apparently using Eclair 2.1 doesn't solve the issue as my brightness is still 70% ... I've tried the batterystats.bin fix and same thing happens. Damn !

It's true. JM8 and the battery fix doesn't help.
But I found that when I turn my connection from 3G mode to Wifi mode, my battery drops only 10% overnight.
I think there is some problem in the 3G connection.
Do you think this is kernel related?
One way to keep the drain down is getting a black theme such as the Transparent theme and setting a black background. Because of the AMOLED screen black is basically 'pixel off'. It helps just a bit.
I have similar experiences with WiFi vs. 3G, 3G drains battery awfully fast whereas WiFi seems to be consuming significantly less power.
So I've been having some issues lately with my battery life and I think I've found the cause. Its a wakelock called "Copsdaemon" in my battery stats. It uses over 60% of my battery as it keeps the CPU on for long periods of time. It also stops my phone from entering deep sleep. Has anyone else experienced this issue? Is there any fixes for it? What is this process and mainly how do I stop it? Cause it is super frustrating to have a battery life of about 10 hours with not much use at all. Thanks for any replies!

Hi, its to do with the 2G network. If your in a good network area set it to 3G then deepsleep will work. If you havnt got a good 3G signal then I don't know apart from a rom change

Has anyone found a solution for this yet? This thing is draining my battery like crazy. Gets me at the most 2 hours screen on time (half of what I used to get on KK). Tried both CM12 and AICP and both have this same issue.
Here is a link to my battery stats - Cell Standby seems to be the biggest battery user when this Mobile Radio Active is going "nuts".

If I catch it early then reboot temporarily fixes the issue but if I don't then in a day's use this Mobile Radio Active can take up to 8-9 Hours of activity! Please help!
This is still an issue.
Stll an issue in the official 5.1. Weird thing, it doesn't always happen... I get this drain from "cell stand by" like 2 days out of 4 or something like that.
It's pretty annoying since the battery really last longer with Lolli, except when this issue is ongoing.
Usually cell standby draining your battery hard is from a weak signal while on data. Not Wi-Fi.
Look at the graph in the stock battery section in phone settings. A lot of red and yellow for the signal bar would confirm that. :good:
Hi - I have a OP3T loaded with NOS 9.0.
Most folks on NOS 9.0 have said that they are seeing great battery life (about 0.5%/hour drain when idle). I am usually seeing about 2%+/hour drain when idle, and I haven't been able to isolate the problem. The folks over at the OP3T NOS 9 thread recommended BBS and posting here.
I have BBS purchased and installed, and I have attached my dump file. There's a lot of stuff in there!
Can anyone provide tips on how to analyze the dump file to identify the mystery battery drain?
Thanks,
GJ?
Adding a second BBS log file for approx. 8 hours of overnight idle time. I was losing 2..3% / hour over that time.
BBS says that my phone was in Deep Sleep 84.7%. I've seen 5%-10% better on Nougat, but this doesn't seem too bad. I don't think that's enough to be losing 4x as much battery life as I saw just a few weeks ago.
Could my problem just be that my OP3T battery suddenly went bad?
Can anyone help me about high battery drainage during standby?
I get upto 45% drain in night with Data OFF (6-8hrs) This is strange. On stock, the drain is about 3-9% with Data ON. Naptime helped one day only, it reduced drain to 6% , but from next night, usual 30% drain happens. on every aosp roms for me, both Oreo and Pie. Any solutions
Found a fix myself.
