I noticed that when I leave wifi on all the time, it drains battery horribly. left idling for 23 hours, it drained the battery 30 percent doing nothing. if i set wifi to only always on when charging, it'll drain maybe 10 percent or so.
I noticed it's just this tablet. my nexus 7s never had such wifi drain. I want to leave it on because i hate that upon wake, when it has to turn wifi back on, it's so laggy for a bit because everything is syncing. kinda annoying.
anyone else notice this?
A bit of reading for you.

Install the free Juice Defender, you cannot edit profiles in the free version, so just install it and turn it on, and forget about it and let it do it`s magic

Even though your wifi might be enabled all the time, maybe it`s not being used as much, maybe some apps or settings, stop wifi from sleeping or you could have a wifi noisy environment meaning the wifi transmitter has to use a stronger signal to break though the noise, meaning more power is used.
Lots of maybe, I dont really know, it`s just a guess.

Is it normal for the back of the phone (around camera) and the screen to get warm when using the phone?
Nothing strange in battery stats, I guess.

see the same under load, so yup sounds normal.
I've not had an android phone that didn't get warm while I was using it and I'm on my 4th one now.

Mine was a bit warm as well last night but I was downloading over 4G, texting, browsing and navigation..
But after I stopped it cooled down in like a minute or so.
My Nexus One got RIDICULOUSLY hot during navigation ALONE. Then the touchscreen would go haywire.
Any phones will tend to get warm during use. And looking at your screenshot, that's a normal load. Nothing to worry about.
I did a Google search for the same problem and got to this thread. I just got my Nexus yesterday and the top right hand side of the phone (I'm assuming that's where the Wi-Fi antenna is) got quite hot about 20 minutes into activating my device.
My phone downloaded about 600mb worth data over that period (downloading apps from the Market) so I assume that was the issue and didn't know if the phone was supposed to get this hot. I've been using the wi-fi sparingly since (no heavy data download) and it is not that hot now. Just wanted to share.
Mine also gets warm there, I assume it has alot to do with the modem as even if my screen is off and the phone is just acting as a hotspot, that area gets fairly warm.
I remember my Nexus S get warm sometimes, but very rarely and there was always a good reason for that (heavy downloading, buggy ROM, buggy app in some loop).
Thanks for the replies!
What the heck killed my battery? This is with the extended battery and I started from a full charge after flashing a new rom and clearing battery stats..
I turned off all connections, and turned off sync.. Sat the phone down and went to bed after about an hour of web surfing.. I went to bed with 70% left and woke up 6 hours later with 37%...

Its all in the last screenshot. Keep awake time is huge. That's the bug if I had to guess.

That keep awake time is normal, nothing strange there...
Your story of browseing for an hour then going to sleep for 6 hours doesnt match your batteries' graph.
According to your story, there should have been a sharp decline from browsing web since the screen would be sucking the power, then a very slight decline from being idle, something was either running in the background (facebook maybe, it has a high % of usage) who knows?
Yeah idk.. If you look at when wifi was on that was when I was browsing.. Then after that there is a steep decline which doesn't make sense to me.. I don't think it was Facebook or anything because all data/sync was off...
I know it takes a day or two for a new rom to settle in but I certainly wouldn't think it would have that large of an impact

I read somewhere that there is/was a bug where after a reboot Google talk or maybe google+ launches the camera in the background which keeps running until you manually open the camera app and close it. I believe I read it some where on Franco's kernel post. Not sure if the bug is still there and if it's the culprit here, but might be worth investigating.
So I charge my phone all night, take it off the charger to go to work at 6am by 3pm my battery is at about 8 percent. Here is where it gets funny, if I turn the phone off then back on I have about 59%. How does that happen

Sorcery. That's how.
I'm guessing the reason your battery gets drained so quickly is because of the poor network coverage.
Could you also provide a screenshot of the apps/programs/hardware that have drained your battery? By that I mean the screen you see after hitting battery under settings.
The fact that it goes up so much after a reboot is very weird indeed. It usually happens the other way around with mine, the battery level drops about 15% for me after a reboot, which I also find weird.
I have had the same expierence with my phone as well. Dont understand it either.
I suggest you use a battery calibration app or s-off/root and install Clockwork Mod recovery to clear your battery stats and run a few cycles. Your phone doesn't know where full is and can't detect it as well as we'd like.
Sent from my Galaxy Nexus using XDA App
I think you need a battery calibration. Before i calibrated mine would drop 10-15% sometimes but now it is good. I would also add expect a small margin of error if you were using your phone heavily and it is warm/hot and you reboot. Some people report, myself included, that you might see a slight spike after your phone cools down.

Hey all,
I just thought I would post this as I thought it was quite incredible.
I don't know what HTC's stats are on 'standby time' (which is usually how long a phone will last with no radio gear active) but look at how long my Desire lasted when I took the sim card out

That's 302 hours
Just Sayin'...
Another thing that I noted was the vast amount of 'awake' time vs 'screen on' time, sometimes lasting hours.
What does android have to do so desperately whilst the screen, radio, wifi, in fact everything is turned off??

Its not Andeoid really. My best bet would be that Go Weather app.
via xda app
I'm not entirely convinced that it is, I could uninstall GoWeather or do a /userdata wipe and retry to see if it'll last any longer?
Even if you put it on airplane mode, the apps you have would still try to wake up every now and then to try and refresh themselves. If you have a resource hungry app then it will wake your device to do the task it needs to perform. It may or may not be go weather app but there is something installed on ur phone that is keeping it awake even on standby. That's what I think anyway.
via xda app
Ha ha ha ha...looks about the same as my desire. I got one hour battery life on idle once with 3G off, wifi off and most of my user apps killed.
My phones been charging for the last four hours and it hasn't moved from 75%. It dies in ten minutes If I use the data connection when it's discharging.
hello,
so i just unplugged my phone at 98% right before my shower and it drained 7% within the 10 minutes (not even) that i was in the shower. bluetooth was on and the phone was in the shower with me (not literally but in the bathroom with me) as i was listening to music o
via Spotify on a bluetooth speaker.
anyone have any ideas why my battery is draining so heavily? only app that was running was Spotify then settings was the only thing open in the background. brightness was at 48% as it was hard to see it otherwise. data and wifi are on but signal for both is good.

Brother i know what you are feeling. Having data on when you are using wifi still results in drain, turn it off
I have the same problem as well and i dont even listen to any music on mine except the FM radio
LG G3 is the biggest piece of crap ever. Will never buy another LG Smartphone again

i love my g3 but i noticed that i took it into the shower with me today and did the same thing except it was charged to 100% this time and ir stayed at 100% the whole time. my shower wasnt much if any shorter or longer than my last one.
yeah im doing that from now on and now im using the free wakelock indicator to see if it helps at all. if not ill re-download 2x battery saver as i know it works.
