Click to expand...
Click to collapse
It's scanning because apps are trying to connect. You will have to remove anything that connect to the Internet or get a firewall

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.
Hi
I have my S2 for 8 months now, flashed numerous roms non stop, but the last 2 months i stayed at RR 3.1.2. This is the latest JB RR which works rock stable for me. Untill recently, i'd say 2 , 3 weeks max, my Sim card gets locked every now and then. This means only Emergency calls are allowed, and i have to re-enter my PIN code. The phone doesn't reboot or anything, it just cuts off the signal and wants my PIN again.
This is bugging me for 2 reasons:
The phone is searching for networks non-stop, consuming a lot of battery
I am not reachable, since no signal.
Once i enter my pin it goes back to full signal strenght HSDPA.
I wonder if anyone else had this problem before, and if yes, was it a software or hardware issue.
Any other ideas, suggestions, even thoughts are more then welcome.

The phone is already on for 10 hours now, and as you can see it looks like it rebooted. It did not as my recent apps are still there, and in Status phone i can see it's not resetted.

Hey community!
We already discussed the problem about the HOX+ Wifi Problem and SmartSync, which is perfectly messed up HTC Dev...
A nice guide to avoid the HOX+ going into deepsleep at night is written by baha76_s:http://forum.xda-developers.com/showthread.php?t=2089452
My problem:
My HOX+ turns into deepsleep after ~15 minutes.
Not receiving any Internet notifications such as WhatsApp, Email etc. AT ALL. (All day long!)
HOX+ only catches notifications after waking up, or within 15 minutes after standby mode became activated.
I've been using baha76_s's trick, making my HOX+ NOT DISCONNECTING from wifi.
So it's connected.

BUT:
Even if my HOX+ is shown up as connected on my fritz!Box 7390 (See picture), and even if the powermanagment shows that the HOX+ is always connected:
I have 100% package loss by pinging my HOX+. (See picture)
I need help for this.

Cheers mates!
I and some other people on android central have had some strange activity with the battery drain and the internet app since the last official ota. I did a little experiment last night and put my phone into airplane mode after charging it and restarting it. Sure enough, this morning:

"lightbox_error": "The requested content cannot be loaded. Please try again later.",

}
I would do a factory reset but my laptop died and I'm away from my desktop. Has anyone else experienced this aberrant internet activity on the stock ROM?
Have you tried disabling the syncing options under your Google account for things like internet to try and see if it changes anything.
You should use an app like better battery stats (available free for XDA users here on the site) or gsam battery monitor to see some more specific information.
Also use one of those apps to see if its using power when it has a data connection. In other words if its using more battery because its constantly trying to sync something while there is no data connection.

Hi
Unfortunately despite many attempts, the phone from upgrading to marshmallows no longer comes into deep sleep.
It's been a year since, I tried everything but nothing, unfortunately I was always on oxygen for stability, I formatted it many times but nothing .. and before that happened it also stopped running the accelerometer, in fact I updated my phone in the hope of doing it again but instead it created another problem.
Now mount the moos 3.6 with the boeffla kernel.
What can the reason for not getting into deep sleep depend on?
Help me please..
I also have experience in compiling rom and kernel and, use adb and i know linux (centos, redhat, ubuntu, debian) if it can help..
I leave various screen shot attachments if it can help..
???
Tanks for any help!
Sorry for my English but im italian

wifi is the problem. turn off wifi scanning.
cellphone signal is also weak. try switching to 2g and manually toggle to 3g/4g when you need it.
