I've been noticing a good amount of heat up by the camera during moderate use. I thought this was a CM7 problem since I had been on it since day 1, but I am now on UnNamed and the problem persists. After some googling it does seem that many other people are having this problem. Not on WIFI, and not in a poor signal area either. Just wanted to see if anyone had any leads as to the cause. What is a good app for monitoring CPU usage by app?
Yes, it may get a little hot but it isn't something to worry about as far as I know. I've gamed for three hours straight and not had any problems except for a low battery life!
yeah mine gets hot near the camera during use but i dont think its a problem
I use a battery monitor.
From what I've read, it will shut off for protection. I've heard that as long as it doesn't ever get too much above 130 F, you should be OK.
Now if it constantly stays high, there may be a problem. Mine stays around 80 F most of the time and the highest I've ever seen is 99 F but i don't game much or use my camera. One thing you don't wanna do is charge it while hd gaming or charge it in a hot car. My infuse reached 146 F one time doing that.

Somehow 'Words with Friends' caused my phone to really warm up a lot. More so than I've seen with any other situation and on numerous occasions. Luckily I suck at that game and uninstalled it...
Mine is cool unless i put a thick case then itll burn up

When I first got CM7 running on this thing, I tore through the market installing the apps I'm used to. When I was finished, I noticed that it was indeed a bit warm in the area you described. It wasn't hot enough to cause discomfort, just warm enough to note.
I notice when my phone gets hot in that area when it is around 30% remaining and I charge it. I also notice that when it is charging, it really isn't charging but battery is draining. When I got home and charged it at 30%, I left it sitting there for about 30 minutes and when I checked the phone again, it was at 25%. GPS and wifi was turned off. I decided to power down the phone and remove the battery for 5 minutes. I started working fine after that. I noticed it getting hot again today when I plugged it in to charge at 40% but this time it actually was charging. I am running stock rom but rooted. Should this be a concern?
Seems as though a lot of people are having a variation of this problem. Hopefully it is addressed soon.
The CPU will always get a bit warm if it's running.
If it's getting very hot when the screen is off, you've probably got some background task wakelocking the phone.
My phone's screen gets pretty hot when I run web videos/flash videos on HSPA.
Runs a tiny bit warm when i'm running pristine 3D Tegra games on it...otherwise no.
The bottom right side of my NT heats up during normal use. Also the battery seems to discharge really fast? Is this normal or am I being paranoid. My previous NT overheated really bad once so I excahnged it.
I have been using it for about 30 minutes now after a full charge and its at 90% charge left.

yes,I got the some problem
I can feel it obviously
Is it possible you have a run away app that's eating up CPU cycles? Check your battery history and see if something sticks out.

I have noticed the battery getting warm, but it's usually when I've been browsing for a while. It doesn't feel super hot (like my laptop does) but it's warm. I haven't noticed terrible battery life. If I let it sit idle, it goes to about 50% in 8 hours time. If this is an issue, I want to know about it. I'll have to restore it to factory settings and whatnot, but I don't want a faulty device.

No its normal and is because deep sleep doesn't work, hopefully once CM9 gets released deep sleep be fixed.

There were a number of posts from people who were seeing high battery temps after skipping the OOBE. Did those of you having problems in this thread skip OOBE, uninstall B&N apps yourself, and/or use compromise the B&N applications/services in any way?
Just got mine. I noticed that it does get warm but not too warm to cause panic. Mobile phones start getting warm too if you've been browsing over wifi for a while. Are most people running frosty nooks? Should it not feel even a little warm?
Or maybe you can rate the amount of heat, say from 1-10 how hot does yours get?
My rooted nook gets hot while playing Exitium for half an hour, but not when it's idling.
Not I
I use my Nook tablet quite extensively and I don't seem to feel an unusual amount of heat coming from it. 30 minutes of use and down to 90% is not unusual either. Otherwise, I would have to agree that there is probably an app running your CPU full tilt. Probably not your battery that is heating up either, if you look at the pictures of these pulled apart, you would see that if the battery was what was getting warm, it would be almost the whole back of your NT.

I was actually thinking the same thing. I think the warmth I'm feeling is actually coming from the wifi adapter inside, which would make sense because I notice it when I'm browsing the web for a long time or downloading a large file.
No issues with heating up here.

Only time mine heats up is if I have been streaming from my pc to the tablet via dlna server to watch videos which would either mean its the wifi chip or the cpu heating up.

Just to clarify, you're saying if it is sitting idle - not being used, and the screen is off - for eight hours, it will drop 50% of the battery? I just picked mine up, and after almost 11 hours sitting idle it only lost 5% of the battery. It sounds like you might have an app causing a wakelock.
No heat in mine and it does retain charge while sitting with screen off. I rarely turn it off and charge every day or two depending on use. I read somewhere it is not good to let the battery go completely dead.
Not sure what OOBE is but I have been turning it off to avoid it from overheating really bad like my first book.
Not really sure how to scale it but I would guess maybe a 5 if a 10 is where it wouldn't turn on and a 1 is its cold to the touch.
I used Indrects method.
How would I check to see if a app is doing something like that? Tgps?
I guess I could just leave it on for a day then check to see how the battary is after like 15 - 20 hours.

I skipped OOBE, I used NARS to root. I don't have this problem.
Never heated up for me, not once.
Overall I'm more than pleased with battery life. Watched 40 mins of youtube 720p video with jetvd yesterday (over wifi) and battery went down only by 10%. My SGS2 would've lost like 60%.
What's the longest anyone has managed to stretch their battery life while actually using their Transformer Prime?
I seem to get 2-3 days with average use, some light gaming, etc. but I did manage almost 4 days once:
Well due to my noobness here I can't post a proper link to a large screenshot, but it was 3d, 16h, 46m, 2s at the time of the screenshot.

Not too long for me, only a day and a half or so. Then again, I use this thing a LOT.
I stretched mine about an inch before it died...

Thanks for the offer, it let me fix the link myself since I made a few more posts tonight.
I have managed to run it out in half a day before with heavy use, so I know it can be a hog when it wants to. Overall I've been pleased with the battery life I've managed to get from it thus far. Only once have I found myself in a position where I wanted to keep using it but the battery was low. Every other time I've been plugging it into the charger just to top it off in case I need it more the next day.

Obviously very dependant on use.
This screenshot shows my typical use i.e. undocked, wifi on 24/7, in sleep mode a lot, but awakened every few hours for a bit of browsing etc.
One thing that did occur to me was the small battery loss when using tapatalk a lot. This is presumably because I have the display with black background and white lettering. Wouldn't it be good if there was a web browser that allowed the same ? or is there ?

On standby, mine lost 56% in 16 days during an RMA.
Wow, pretty jealous of you guys and wonder if I have a battery problem.
I get about 2-3 days if I use the tablet for about 2 1/2 to 3 hours a day. Is this normal?
I didn't do the full charge out of the box as recommended though...
Would say it is normal. With Wifi on, all sensors on, Balanced mode, auto brightness on (mostly around medium brightness), normal ips mode mostly brwosing the web and playing I get around 6-7 h continuous screen on time. Measured with better battery stats. I think this is quite good. Everything without dock.
Wow...my battery life blows. I've been on it constantly surfing online for almost 2 hours and I'm down to 72%. My battery just drains so quickly when online on 25% brightness. I'm only syncing gmail.
OK what in the hell am I doing wrong? Stock non rooted prime and I'm only getting around 6 hours of battery life out of it per day, I got more out of my tf101 then this....
Wifi turning off when screen is off, its sleeping, brightness on auto no super ips.

I've been able to get about 12-15 hours of battery life with some pretty intensive gaming. you should probably get it replaced for another prime.
Crap well I can't imagine it could be anything else other then bad batt
Sent from my Transformer Prime TF201 using XDA Premium HD app
I get the same after the last .21 update. Can you look into you batt stats? Mine shows 60+% for wifi usage.
Ya mine Is normally a little less around 44%
Even if I turn my wifi off every time I turn my screen off I get the same amount, less then 7 hours before it dies. Are you getting more even with the new update and the wifi ussage being higher?

Hi, what I have noticed is that on my Prime the battery is very good, 5-10-% drop in 8-10 hours of minimal use, but if I keep it in the dock, it sucks up battery. I found it is much better without the dock. Can anyone test the same thing? I might need to see if I can get the dock replaced and see if there is a difference.
Well after replacing my Dock my issue was fixed, so it can be a hardware issue as well. I also had some stability issues and I resorted to a Factory reset and this is also better now. So now my Prime is almost what it says on the box
Try a factory reset? It can solve all kinds of annoying bugs that might prevent a process from ending properly which may eat up battery life.
Mother fer
So I just spent the last three weeks getting my prime warrentied. They said they replaced the battery and I just did a hard reset and charged it upper all night then ran it today. Nothing special just internet stuff and I have 20% left and screen only on 4.5 hours and the wifi is at 5.3 hours. What the hell could be wrong with this Pyle?
Sent from my Transformer Prime TF201 using XDA Premium HD app
get cpu spy from the market...and check if your prime has been able to go to deep sleep...getting wifi off with screen off does not necessarily improve battery life...rather your device should be in deep sleep mode when screen is off...
if it fails to go to deep sleep and shows continously as awake or running at 102 mhz...try removing some apps which constantly run in the background...
Yeah, I'm getting the same -- about six hours of screen-on time.
Are there really people getting 10+ hours (of *screen time*) on their Primes after the .21 update? I've read in other threads that a lot of people have seen definite drops in battery life after the update, with increased wifi usage/power suspected as being the culprit.
I've only had my Prime for a few weeks and upgraded straight away, so I have nothing to compare it to. But I'd love to hear from people getting over eight hours of usage. Then I'll definitely go with a factory reset.
Ya did that right after I got it back and its sleeping just fine. Maybe it is just that after .21 the wifi sucks the power out of this thing?
Sent from my Transformer Prime TF201 using XDA Premium HD app
Yeah, is possible to get 10 hours+ screen time... with wifi off. Making it turn off when screen off does nothing, cause it actually uses no power while it is in idle mode.
Its when the damn thing starts transferring data when it sucks the battery up.
Being there's so much difference in battery life, I was curious if there might be a bad batch of phones. My phone gets great life and my dad's gets significantly less. He works about 2 blocks away from me and actually has a stronger signal in his building than I do at mine and his battery drops like a rock with nothing running. I'm rooted and froze the AT&T bloat. He's stock.
My serial number contains a PTM and the end number is in the 40000's. His serial number contains PZK and ends in a number in the 30000's. If you have time post your serial # info and how your battery life is.
I returned my ladies OG and now her battery life is better. Even b4 I rooted it drain was better from prior phone. Could be a batch. That's my lead as well

I'm contemplating returning my phone just in case of a 'bad batch,' but I'm afraid I'll get a phone that's even worse lol. I can't forever replace phones. I'm just trying to make it work.
Does this phone have the ability or need to reset battery stats? I know you couldn't do it, or it was unnecessary on the SGSII. Just curious if it's a calibration issue.

Resetting battery stats actually has no correlation with battery life whatsoever. It is not what controls the percentage that we see in screen. I believe it just tracks what apps or system files are or have been using up the battery. Battery stats gets an automatic reset whenever you reboot anyways.
For those with bad battery drain, just try and see what your serial numbers are n post it here to compare.

First time I read it, it blew my mind. Talk about placebo effect.
Jesus...its a SOFTWARE bug...not hardware. We ALL have it. We just use our phones differently.
Dude, you're blowing smoke off an asbestos fire. You have no idea what exactly is causing it.

The battery life on my phone and seemingly most folks is great. Granted some folks probably live on the cusp of LTE coverage in their area and the radio is killing the battery while liking for signal (that happened to me with my EVO 4G).
If it were all devices, then only the battery life fanatics who shut down everything would be seeing 20hrs on a charge.
I think there's a bad batch of hardware or there.

crap battery
my s/n: KPUU 40000's the high end. I dont think its a batch.
seems odd that those who are having the issue are not likely to make to 10hrs on a charge (often 1/2 that)...while others are bumping 20hrs (myself included).
i have 4 emails on constant sync, as well as, facebook, weather, xda and a chess. each day has a couple hours of screen time. 1hr each day of either Pandora or Audible. 20-50 text and @45min - 1hr of phone time. ... in case you think i put my phone in my pocket and forget about it.
granted, i do connect to wifi at home and work. and i live in an area where i have solid LTE coverage at all times.
audible and screen time are my worst battery drains.

We got ours off the box. Not sure where you'd get it in the phone.
Did a little more research. Set them side by side for an hour with screens at same brightness, always on, with Nexus live wallpaper running. Both were hooked into wifi and the microcell. Battery usage over a 1 hour period was pretty much identical (within 1%). Then did some web browsing and hit all the same links and drain was the same. We thought it maybe was just battery conditioning. When I first got it I did 2 full drains and recharges with it off. He did that about a week in and thought it was fixed.
I left and a couple hours later his battery started to tank. Only thing we noticed was his accelerometer hung for some reason and had 5 hours on. He hadn't used anything that should have turned it on so no idea why it got stuck. Turned it off and the battery usage slowed to what one would expect. Then it had another couple minute burst of dropping. that was the last I heard.

The one thing I've notice about my phone is that when looking at my wireless icon in the notification bar, there is something transmitting 90% of the time (download it appears as it is just the bottom arrow blinking). It does this even when sync is turned off. I've gone through the phone and I can't see any app running. Has anyone else noticed this?

I'm convinced there's a bad batch.
My replacement phone literally just ran all night. I had been awake backing up my system with Titanium, and it stalled before I went to bed. TB kept my phone running for 8 hours straight with the screen on and my phone is only at 18%.
If your battery life is ****, return it. Currently running Stock, rooted and unlocked with dormancy fix.
So this is what betterbatterystats is showing me. I'm using around 5.8% a hour that's not the best but that's not bad right?
