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 everyone,
I have noticed that my when my wifi is on, phone drains much less battery. Does that just simply implies that my phone service provider sucks with bad signal quality? Or anyone have any insights on this problem?
Thanks

Not at all, and attributing wifi being on as "improving" your battery life may be a faulty assumption... your drain looks fairly good? its just the awake time that is draining it, would likely have little to no difference on if your on WiFi or not. Looks really good to me LOL I wouldn't be able to get 20 hours on a single charge the way I use mine!
Well, I beg to differ. I am on 2.3.5 and for me also the drain is significantly less if I leave the phone on wifi. I think its because when you are on the network, there is a periodic ping to the tower and also as the signal quality keeps changing depending on the load on the tower you are hooked to, it keeps downgrading/upgrading between H+ and EDGE. I may be completely wrong but I think you always save on wifi so long as we have pethatic network operators.
Thanks,

This dont usually happen. In fact, it only happen once.
All this while, the display always use the most battery life, about 50%
followed by android OS, about 10-15%.
my phone was fully charged before i sleep.
but i woke up with 5% battery left, the battery info says android OS used 60%!!
here is screenshot as proof.
i'm really confused, the phone state is appear to be NOT awake,
but the CPU usage is 1000MHz constantly while i sleep.
all this while i've been using rom tool box CPU slider to underclock it to 1000MHz, so thats the maximum my phone can go. i prefer it that way so its much less warm.
any idea whats causing this? as i mention before, this only happen once.
Even so, i'm very curious about this. any one experience this before? or know whats goin on?

Better Battery Stats thread and partial wake locks is your start point .

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
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
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:

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.
