[Q] Battery Drain, Log Shows Unknown Wireless Event - Captivate Q&A, Help & Troubleshooting

I'm running Cezar's ROM, and I'm having a terrible time with battery life. As most people who use the ROM report fantastic battery life, I installed OSMonitor to see if I could find the culprit.
In the "Message" panel of OSMonitor, I keep getting a lot of repeated messages saying:
[Warning]
SSS: ROAM ~~~~~~~~~~~
[ERROR]
eth0 (WE) : Invalid/Unknown Wireless Event (0x8C0A)
Could this be something to do with my battery drain?

Take a look here.
In post #2 there are some links to threads about the issue. I don't know much about it but an extremely short term fix is to turn WiFi off.
In some post they talk about it being a samsung bug in JPY. In another it's said it can be fixed but I don't remember seeing a solution anywhere yet.
EDIT: After reading more about the wifi bug... it looks like what you have and they have may be unrelated. Sorry. It might still be worth turning off wifi to see if you get a better battery though.

Will fix it in my next addon.

Thanks to both of you. Crossing my fingers that this wifi bug is the cause of my miserable battery - I'll turn wifi off when possible now and wait for the fix

Battery Draining: Please share your Battery_Use>Display % info

Hi, I'm having a problem regarding battery draining issue, no matter Eclair 2.1 or Froyo 2.2, I left my SGS fully charge 100% at 12am and find out it only left 75% at 6am. So you guys can imagine how suffer I am to survive using this phone especially on heavy use. But I really love this phone
The main culprit which I believe is the Display which consumes high power as you can see in my snapshot bellow
I would like to ask your favor to share what is your Display % and Do you have any battery draining problem?
You can find the % info as below
Settings>About Phone>Battery use>Display
Do you have any suggestion how to solve this? Or any recommended ROM that can fix it?
Terima kasih. Thank you. 谢谢. Obrigado. Gracias. Спасибо. Vielen Dank. Dank u. Shukran

More info:
**I've tried the batterystats.bin fix
**I've closed all background running programs
Currently I'm using i9000, Froyo 2.2 xxJPK, rooted, OCLF v2.1, standard TWLauncher
Have you tried turning off 3G and WiFi overnight?
I get the impression that "Display" actually covers everything other than Cell Standby, Wifi, and Phone Idle.
Use the test menu *#*#4636#*#* from the dialler to get more detailed battery history, especially check the CPU usage stats as a runaway process may be chewing through the battery.

[Q] lollipop battery problems

Does anybody know if the .726 firmware has any issues with low battery life and overheating?? I have the update available but i didn't do it because i red that many z3 compact-lollipo users had problems with battery life. Thanks
Battery Issues
I had an issue when I installed it, battery life was terrible the first day. Something about Mobile Radio Active... I turned off Queue Background Data in Power Management and it seems to be better now. I haven't had any issues with overheating, although I might not be the best person to ask, cause I'm not really a heavy user. Just every day apps.
I installed the update immediately because I got sick of not being able to do anything with my sd card! I don't really see any other reason, so if you don't wanna risk it, don't update!
EDIT: Ignore what I said, battery is still terrible. It appears that lollipop's battery stats is just bad. There is something wasting my battery and I have no idea what

I upgraded my gf z3 to lollipop and the damn phone overheats constantly and has an insane battery drain. It usually drops to 40% by 8 or so for her on normal usage (she barely uses it) but since the update it dies before 9pm. There is something seriously wrong with this and I'll continue looking into this. Really aggravating. And the heat is unbearable.

Anyone else with big battery drain on 5.0.1?

Hello
I have this device since yestarday, And what I have noticed that battery drain is huge even when I don't use BT for smartwach, NFC, cellular internet or any other things. With very low usage battery runs out very fast.
Does anyone else have such problem with this device? is it something common?
Well i noticed that, after work around 3 p.m. i had 60% battery and now i have like 30%, very weird
I turned off double-tap-to-wake feature and I'll see if it change anything.
It's not that. It depends on the version you are running. If it's android core apps fault, then you must replace the messaging and dialing apps with some apps from play store. You can see which process is draining that much battery from checking the battery consumption in settings menu.
I have partially solved the problem by disabling double-tap feature and also the one that prevents phone from random actions in the pocket.
I have only few apps intalled and eveything that I don't use is disabled. I'm not going to root my device yet, but I will debloat it someday.
What apps may be disabled? Thanks

Android OS WakeLock from Hell

Hi,
When my My MotoG 2 is connected to WiFi Android OS sometimes keeps the device awake, eating up my battery until I restart the device. It just happens sometimes, not always.
My device isn't rooted yet due to warranty. I disabled everything I could in Settings>Applications.
Any advices?
Hum, maybe Ambient Display is the offender, let's try it....
Well, I've been testing it in the last few days, and it seems to be solved.
I turned off "Ambient display" and installed Glimpse Notifications for similar funcionality. Now Android Os keeps the device awake few minutes instead of many hours.
Hope it continues this way!

This is not how you troubleshoot wakelocks.
You need an app that analyse the cause of it, like Better Battery Stats.
Once you installed it, you've to leave your phone for around 2 or 3 hours without using it. Then you'll be able to see what causes the wakelock.

Please, read before reply.
Without root these apps are useless, that's why I used such a "brute force" approach. And I shared my results here just in case someobe else finds the same kind of problem, not to teach how to troubleshoot wakelocks, there are plenty of tutorials on this subject around.

Battery suddenly drops to 1%

Hello everyone, today I woke-up with my phone pretty much dead, with only 1% of battery. The weird thing is that before bed, the battery percentage was around 70ish percent.
Here's a screenshot of the battery usage:​
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Some details to help me figure it out the issue:​
Auto optimize daily is on.​
Auto restart at set times is on (it restarted around the time that the battery percentage drops to the floor).​
Adaptative power saving is off.​
Background usage limits is configured properly.​
Any help will be appreciated, thanks in advance!​
it's possible the Google services was running (updates and such) and used up a lot of the battery. Google being the OS developer tends to run quite a lot of things in the back without users knowing, and this is quite normal. As to draining such large amount, is your location in a poor data coverage area? if you are, then the phone likely was using extra battery to strengthen the signal. Note that even with wifi connection, data is still used for some activities by the phone.
if this keeps persisting then Google is probably not the culprit and you'll want to report the issue right away to samsung using samsung members app > get help > error report. just be sure to see the drain and immediately report.
Also, I've seen some users install 3rd party apps to track in finer detail on what is using the battery the most. I myself do not know as I don't use it, but you can easily find some recommendations on Reddit i think.
