wifi always on, softkeys lights up even when not touched, etc etc - Galaxy S III Q&A, Help & Troubleshooting

Hello everyone,
I have noticed some strange behavior of my s3. I saw that, on battery graph, even when my wifi is turned off for a longer time, it displays as it is on. The other one problem that disturb me is that sometimes, when i read something or play games, back button and menu button lights up, like i touched it. And, ive noticed also, when I turn off and wifi and mobile data, on screen shows up "failure in downloading data" (something like this, ive translated this from my language to english), which (i think)
causes fast battery consumption. Here is the screenshot of battery graph.

where you can see wifi usage and that from full battery to 20% it takes only 5 hours (battery is new one). Should i change the rom, kernel etc, or something else? Any suggestion will be good.
P.S. My s3 is rooted and riding on factory sw 4.3.
Thanks to all, and sorry for opening a new thread, found this as best solution.

Durty flash a 4.3 rom and check if it still is the same.

Wireless->Advanced and check if is checked "scan for free wifi" or similar voice

[Q] Phone wouldn't turn on and significant battery jump (not a battery complaint)

Hi everyone,
This is not a battery life problem. I've read the battery threads and could not find someone with a similar problem.
My problem: I left my phone locked and untouched while I went shower. Afterwards I decided to check my phone but it did not respond. I tried to turn it on but that failed too. The screen stayed black as if it was off. I ended up taking the battery out, putting it back in and turning the phone on.
The phone did turn on but my battery temperature was 45°C and 48%. My battery was 75% before I went shower. I checked the battery status page and here's what it showed. Notice the vertical drop in battery at the end of the graph.

After a few minutes since restarting:
The android os % also has never been this high before. I've also never experienced any battery problems mentioned in other threads. I use my phone quite often so display is always at the top. This is the first problem I've encountered with my SGS2 which had made me quite sad since it's less than 3 weeks old.
Thanks for reading and would really appreciate any input.

I maybe the last to know this battery saver tip

If I'm the last to know you can make fun of me. Just read in my Get Started user guide if you hit the back button instead of the home button it turns the app off.
That's why I always seem to have several apps running
I hit home a lot, now I know
Enjoying my 3vo
in android the background processes barely touch the battery it's managed well and you don't have to worry about them being open.

Bwahahahahahahah!!!!
With that out of the way, there are some really poorly coded apps that kill the battery even if it's not doing anything in the background. Even if the app does not, it takes away available memory, though it's usually not that much.
P.S. The first line is a joke .
any app that you can close with the back button(android has always done this as far as i know) you can also close in the task manager
but ive tested. not all apps close with the back button(still shows as running in Applications). probably something the dev of the app needs to allow

[Q] huge power consumption SGS2

Hi everyone
i have a strange problem that happens often with my phone,
i noticed there are some certain apps or games cause my phone to consume power more that usual.
what happened was, i fully recharged my phone, then installed (Where's my water, the free version) from Android Market last night, and i played it for a while, then i went to sleep and the phone on the stand by mode.
when i woke up this morning and i found that my phone lost almost 40% of its charge over night.
the only solution to recover from that high power consumption is to restart the phone, but it is really annoying!
i took a snap shot to the power graph and i made little explanations on it.

Sorry for bad English!​
Download better battery stats from the market and it should tell you what was eating your battery. I'm guessing an app is keeping your phone awake. Check your uptime and awake time to see if it seems to close in numbers.
thanks for reply, but as you can see from that picture, the phone does not show awake condition while it consumes power.
anyways I'll try to install one of those battery monitor apps to identify what's wrong with the device.
thanks again
please help

Can't get rid of this wakelock

I put the phone into flight mode over night and the drain was a bit less than when on. 15% in 8.5 hours, compared to the 25% with it on.
However, as you can see from the screen shots, something is still causing the phone is "wake up". I've turned off everything in the process of trying to find out what it is, but still cannot find out.
Can someone have a look at the shots and see if ye can pick out something.
I must say that the connectivity issue I'm having(keeps giving me a connected to wifi network notification every few mins) could be causing these wakelocks?? I don't know myself.
Anyways, I'd appreciate any thoughts on how to sort out the wakelocks.

s-voice has a wake up feature turned on by default
Continuously connecting to Wi-Fi is the power saving mode.
You can deactivate it by dialing *#0011#, menu, Wi-Fi.
The only way I found to allow the phone to truly sleep was not to have Wi-Fi on at all. Off when screen off also seems to work.

4.5hrs screen time looks pretty good to me. I'm lucky if I get 4hrs

Wakelocks (?) on Wifi

Hello everyone,
I've had my GS3 for over a month now and I can say I am quite happy with it. Battery life is rather consistent (I come from an Apple IP4).
There is something that is bugging me though. Every time I am connected to a wifi network, battery drains faster than usual. Whenever I check the battery usage, I can see that the phone wakes up for short periods of time repeatedly, mainly when I am using wifi. Here's a screenshot of it.

I am on 4.1.1. No custom ROM and/or rooted.
Hope you can help me.
Something's waking your phone regularly... not WiFi. Use BBS to monitor what is doing it.
It is likely to be an app using a network connection for data retrieval.
My guess is that an app is set to sync\download\upload when you are on WIFI only, and stuck in a loop. Install Better Battery Stats, charge your phone fully, put it on WIFI and then leave it for an hour. Then check and\or post your BBS log.
Happy hunting.
Is there a free app that i can do that with???
Thanks a lot.
Probably wlan_rx_wake wakelock
There are custom kernels for that
You know, as i said, I've only had the phone for over a month. More info on that would be greatly appreciated.
