Hot/warm when using - Samsung Galaxy Nexus

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 killed my battery?

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.

Weird battery activity

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.

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.
My grandma beat me down and took my nexus. Sent from a jitterbug with beats by dre.

[Q] Warming up?

So warm up check is something you can do the moment you get the phone (or at least it was like this with the Sensation).
Can someone that has already received the phone comment if the phone has a warm up problem while playing games or web-browsing etc?
(I know most of the phones warm up, the question is if it's fine or if it's becoming an oven like the early versions of the Sensation)
Been toying with it for about an hour now, battery just about to die so I can charge properly. No heating issues what so ever. It is as cool as ice tbh. I've played Glowball a bit and the screen has obviously been on for an hour now, 6% battery left, started with 27. Wifi on, data on, heavy game on. It does NOT heat up and Glowball runs perfectly smooth for me. I will be doing more tests in a day or 2.

Another battery drain with screen shots

Ready to go back to @??/€..... hate that but im sick of this battery drain randomly
Ive found a few things to be consistent maybe others can chime in.
With google services. Its not always bad. Recently had everything on and no issues. Including gps, Google now, location services etc.
I have found out to last more than a work day. Come home with 45-50%
But today..... Phone just restarted randomly, not the first time either. Usually there is an update for something and the phone restarts to update an app or whatever.
Today, just restart. Then 40 min to 1 hour later. Phone is getting HOT, I look and I had gone from 70% batt to 56 in minutes. Then to 40 then 15 and all the way to 2%
I wanted it to shut down on its own and restart it with a charge but, I had to drive home and car isnt 100% reliable and I didnt have a car charger. So I plugged it into pc to get a few % up.
Google plus went rogue I guess. As you'll see below. But why? And why doesn't @??/€ have this problem?
I just want the phone to last a full day. I dont even use it at work hardly at all with the exception of a bit of tapatalk and facebook......
Screen shots below for help.

Not to state the obvious, but have you considered freezing or uninstalling Google Plus?
Also, check out the link in my signature about keeping Google Services in check.
I forgot to mention that I'm on 4.2 .2 . In addition I didn't do anything to the song, I did not force stop loss, nothing. And everything is back to normal today

why does wifi always on kill battery so much?

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.
