How much heat can the N1 take?

So the other day, I forgot to close an app down--the Schwartz Unsheathed, if you are curious--and when I fished my phone out again, it was hot. Very, very hot. Battery information indicated 41C which, in the grand scheme of things, isn't that high (wouldn't worry me with a PC's graphic card, for example, or CPU) but it felt incredibly warm to the touch. Fine, I shut the app down, removed the battery cover and let the phone cool down. No problem.
It might be the apps I've been trying since then, but I have been experiencing performance and stability issues. Things slow down sometimes. On the Desire ROM, Rosie kept force-closing every now and again. On Enomther's which as we all know is just about the stablest thing that ever stabled, Launcher2 does ditto (the Launcher Dock may be the culprit, though, as it seems to do some weird **** and I've removed it since. Fiddling around with BetterCut also seems to cause force-closes). So could that be it? Did the phone overheat (but if so, shouldn't it have shut itself down) and now something's broken? Getting antsy. :/

41°C should not be a problem, but consider that this was a measurement from the battery pack and that a sensor like that can easily go +/- 5 to 10 degrees.
so well, some chip on the nexus could have gotten way hotter than 41°C. maybe something fried, some defect that was already there and now its really broken.
still, this can be a bit subjective, the phone will seem broken if you think it's broken you can always do a factory reset, reflash the current rom and try from there.

Yeah, could just be my own jitters--I'd experienced issues before, usually caused by a ROM or whatever--and lately my PC's been having problems, so it might well be some kind of placebo effect. Unless it and my N1 magically entered a symbiosis or something.
Thanks for the quick reply.

once my phone accidently fell onto my bed and under my pillow while i was charging it over night and i woke up at 4 am and found a burning out nexus under my pillow. i unplugged it and nothing seemed damaged but it still worried me.

I think if you are worried about it and you are rooted you should install SetCPU. It has a profile designed so that is you his a preset temp it will down clock your CPU.
I use setCPU to save my batterylife ie.
100% - 50% run full cpu on demand.
Idle/Standby downclock to 400Mhz
50% or less down clock to 600Mhz on demand
20% or less down clock to min.
I also complement this with locale for low bat. dimness, wifi off, bluetooth off. etc.. etc.. ( a little off topic I know)

Well, looks like updating More Icons Widget was what did it; things seem to work okay now.

Was wondering what the maximum advisable temperature is?
Maybe the phone has protection for the CPU? but Li-ion batteries dont like heat, it shortens their effective life.
my battery reached 44.3C yesterday on a 4 hour journey in the car using co-pilot and the phone actually net discharged despite the fact it was on a 1A USB charger for the entire journey - about 80% at start of journey and 20% at end.
I've installed setcpu now and set the temperature profile to drop the max speed to 768 if temp is >44C and another one to drop the speed if power is less than 30%, may need further tweaking though. This was not in my car and the back of the phone was effectively unventilated, in my car I have an open backed holder near an air vent.

G1 shuts off randomly and thinks it's dead?

Hey, guys, I tried dong some research but I can't find anyone with a similar problem.
I've got a T-Mobile (USA) G1 and I've got Cyanogen's Eclair ROM flashed on it. Prior to flashing Cyanogen's ROM, I was using OpenEclair. OpenEclair was working [relatively] well until my phone randomly started shutting off. I thought it was a battery calibration problem, so I recalibrated my battery by letting it die completely and then charging it fully, but that didn't work. I flashed Cyanogen's Eclair and hoped that my problem would be fixed, but the problem still persists.
I can't really isolate the problem. My phone can shut off in the middle of a call, in the middle of writing a txt message, or without me even using it while it's in my pocket. It shuts off regardless of the battery level (I've seen it shut off at like 97%). This wouldn't be THAT bad except the phone refuses to turn on right after it shuts off. When I press the power button, the phone will show the G1 logo for a few seconds and then shut off again as if it was dead. Sometimes if I press the power button, the phone won't turn on and I'll see the LED flash red which gives me the idea that the phone "thinks" it's dead. In order for me to turn the phone back on, I need to plug in the charger. This is becoming extremely annoying.
Does anyone know what the problem could be? I would try wiping/re-flashing but I don't wanna lose all my data :/
Thanks,
Gerard

I'm having the same exact problem ever since installing cyanogen 5.0.7 Test 1... so im not sure whats going on but i went to T-Mobile today... and they said my battery is warped or somethin not to tech savy... yet it was working fine like totally so... hmmm anyone know anything?

yea this has happened to me too! It shuts off randomly then i cant turn it back on until like 30 minutes later without touching it. I noticed that it happened after i flashed a open eclair rom that wouldnt start but i did flash it correctly. I have wiped battery stats and dalvik cache. Well i hope we can get some answers

I had the same problem I have tried just about every rom out there so dont remember when it started but i ordered a new battery off ebay for 10 bucks and havent had a problem since

So you think it's a hardware problem? I find it kinda hard to believe that all of us coincidentally got this problem after installing Ecalir ROMs...unless Eclair destroys our battery somehow?
:/

yeah same here but mine started with Amon Ra 1.2.3 and the blue haze rom. I updated my recovery to the latest 1.6.2 I think and switched to htcclay's superfast and the danger spl slso tmobile is comping me a new battery just to be safe, although switching rom's seem's to have helped my battery life a little. hope this helps someone.

Have you tried replacing the battery?

Nah, I'm part lazy and part unconvinced that it's a hardware issue. I mean if the phone reads that the battery is like 95% charged, why would it just give out randomly? I don't know much about hardware though, so maybe I'm wrong...
I want T-Mobile to get a new Android phone that's like incredible I want a new phone already damnit!!

im just gonna buy a battery on ebay or something because my battery does look kinda swollen so it could possibly be the battery. Gonna give it a try though

You think you could update us when you find out whether it changes anything or not? :/

This phone gets me really frustrated because first it started shutting off and now i have a unresponsive lock screen! I push all the buttons and the screen is black like if its turned off. I have to do a battery pull but theres a risk of the phone not turning back on and shutting off on the g1 screen. I was planning to buy the battery today but i think im just going to use a different phone for now. I hope someone can really resolve this problem. Cant wait for the samsung galaxy s

For what it's worth, I started having the same issue last week with my G1. I think it's entirely coincidental that you switched to the CM 2.1 Test branch and your phone started getting screwy.
I looked at my battery as the first suspect, and what did I find when I pulled it out of the case? A badly swolen battery. By the end of the week, the swelling had gotten so bad that it was visibly bulging the plastic backing on my G1.
I took it to 3 separate T-Mobile stores looking for a replacement battery. The first two were of no luck, but the 3rd finally had one in stock. The CSR saw my battery and almost freaked out. She says I was lucky that it didn't pop because it was ready to at just about any moment.
Long story short, since replacing my battery, I have had ZERO issues, and my battery life has once again been phenomenal (well, for the G1).

I just checked my battery and I think it's possible that it's swollen. On the side where it says "htc Innovation," is it supposed to be perfectly flat? There's like a rectangle that's slightly raised above the rest of surface. I'm a little hesitant to buy a $50 battery if that's the way the battery is supposed to be.
Thanks,
Gerard

Spontaneous power off - sunspots?
Yes, this happened to me fairly frequently about 3 months ago. Now it happens (maybe) once a week.
In my experience, it isn't a Cyanogen issue - it would spontaneous die when I used Enomther's official rom, SuperD (one of the previous versions), and some others. That made me think it was hardware, but ... I haven't changed hardware, and still drop the G1 into my pocket like usual.
So if it isn't ROM software and it isn't hardware, what is it - sunspots?

It should be perfectly flat. A new, good battery does not have the bulging rectangle in the middle you are talking about. Mine did the same thing. In fact, both sides were swelling. The battery would no longer sit flush in the back. My theory was simply that some sort of movement was causing it to lose contact and shutting off the phone.
If you take the battery out and lay it flat the table, you shouldn't be able to rock it by pressing an edge. If you can, your battery is dying.

I just bought a battery yesterday on amazon for 15$ You should check it out. Hope this battery resolves my problem. I also fixed my lock screen issue. I had set cpu to 120 instead of 128 so it unresponsive.

I have the same problem, and indeed when i now look at it my battery seems a bit swollen. I ordered a replacement battery on dealextreme. They have a few different battery replacements for the G1 for cheap (and lots of other things, regular customer) with free shipping. So i hope that will fix my problem .

I found this thread because I've been having random shutoffs as if the battery were pulled (black screen immediately, no "Shutting Down" prompt first), and it would only do this when NOT charging. This started happening when I first ran Firerat's all-in-one script but I think it was coincidental. So anyways, I found this thread after wanting to pull my hair out because of the random shutoffs, and sure enough, I pulled my battery and it's a bit puffed out. Time for a new battery.
My question is : does anyone think this is a result of the extra strain placed on the battery / heat generated from being overclocked? Once I get a new battery, I'd like to prevent it from happening in the future.

definately a battery problem. had the same thing on my g1. got into a whole big argument about how it WAS NOT PHONE in the cyanogen6 thread. guess what....it was my phone.
its not the rom. its your phone. seriously.
also, just to point out, most of us here got our phones relatively early in its release, and lot of people are having this problem now apparently. battery has life of 2yrs by my calculations.
if you can mimic a reboot with the phone plugged into usb or wall charger...it may be rom. but if you phone DOES NOT DIE while PLUGGED IN...ITS YOUR BATTERY.

Had the same problem with my 2008 bought g1, swollen battery and random shutdowns. Just inserted an new bought battery. Hope it fixes the problem.

[Q] Phone Signal and Battery Drain -- is there a correlation?

Hello Everyone,
I am new to the forum, but not totally new to rooting and flashing ROMs. I have a MT3G (second android phone to come to the market...yes I'm old school ), rooted and flashed CM7-Gingerbread 2.3.3 and it's working very well.
I also managed to buy a NookColor, immediately rooted it and flashed phiremod nook v5.1. and everything is very good. My Quadrant Score is 1485
However, what I've noticed is that if I compare the battery usage on mytouch 3g vs the nookcolor I see something interesting and I think it might have to do with the overall battery drain I've noticed on the nook....I'm hoping someone here can shed some light.
When I go to my settings > about tablet > battery use, I can see a graph on the top. If I click it, it shows a nice relationship between time (x-axis), battery % (y-axis) and underneath it are 5 variables (Phone Signal, Wi-fi, Awake, Screen on, Charging). These variables are key because you can see what is really draining a battery.
See the two attached images. One is from mytouch 3g and the other is the nook. What you can see is that when my nook is sleep, it drains a lot faster than MT3G and in fact what you see is that the PHONE SIGNAL is constantly on, where when my MT3G is sleep, the PHONE SIGNAL IS NOT....
Is there a way to completely remove this 'phone signal'...I suspect we can get more battery life out of our nook if we can just remove this!!!
Thanks for reading.

easy to do if you have adb.. otherwise use terminal.
rename the following files in /system/app
Mms.apk
TelephonyProvider.apk
Phone.apk (phone will keep forceclosing.
reboot.
If you are not using adb, just force power off using the power button.
When it comes up, you will have much better battery life.

Yeah, I saw that posted somewhere, and I've done that. So does the phone signal still appear on yours after you renamed it?
I wonder if this procedure is enough.....

Enough to remove Phone from being listed in Spare Parts? Yep. It won't change anything.

CM7 is really bad with the battery. It doesn't sleep properly. The phone or lack of phone has nothing to do with it. It doesn't have a cell radio after all ;-)
Apparently there is a bug and it crashes or something? when it sleeps. I read that the devs just disabled sleep until they can get it fixed. I think that will probably happen after video is all working.
It still easily lasts through the day with a fair bit of use though. I just charge every night instead of every third ;-)

Okay, so it's safe to assume that the devs are working on this for future ROMs/Kernals? I really like my nook even though I just got the wifi-xoom today.

There's already been a 20+ page thread on this, where comparitive testing found no actual diference in battery life by removing those functions. The result is a purely cosmetic change where the power consumed under "cell standby" is shifted to "phone idle" or something else, I forget exactly. Any perceived improvements in battery life are a placebo effect and/or simply the result of the variables in different day-to-day usage.
Removing them also causes Market problems with certain apps not showing up due to "incompatibility" with devices lacking those functions, which I suspect is why they are not removed in the first place.
The NC's "high" power drain on CM7 is because it's not allowed to actually sleep due too a kernal bug which prevents it from reliably waking up. This will get fixed eventually. Right now, "sleep" simply turns off the screen.

[Q] Galaxy S batteries - short life

Hi
Can see a number of threads about short battery life, none quite match mine:
When I got the phone about 6 months ago I took it abroad with me in the first few weeks. Battery life with normal usage was about 24 to 36 hours with fair use.
Dropped the phone, back came off, battery fell out and gold contacts got damaged.
Ordered replacement OE battery from Amazon. Looks identical to original. Battery life as before, for about the first two weeks. Then got worse and worse until down to about 4 hours. Sent it back, replaced. Replacement is going the same way.
Haven't done anything with the ROM, it's all as it originally was, albeit I've installed more apps since it was new.
Battery meter thing built into the phone (in Settings) shows nothing remarkable.
What is odd, and coincidental: if I leave the phone next to me in the house, it won't always pick up emails on ActiveSync (Exchange) unless I activate it (e.g. bring it out of power down mode). At which point you can see it's dropped Wi-Fi. The icon has gone. A second or two later it reconnects (though not before it's used some 3G data - 3G is OK upstairs, barely a signal downstairs as we live at the bottom of a hill so often drops to "G") and then brings down the emails.
This means it churns through 500MB+ of data over its own 3G connection in a month even if I don't take it out of the house, and even when Wi-Fi is available to it, it chooses not to use it. Wi-Fi reception is pretty poor, compared with e.g. our laptop (that shows excellent strength downstairs, phone shows one bar). It did not do this when I first got it. Curiously my old HTC phone did this too, it struggled to switch properly between its own 3G and Wi-Fi and just got stuck on one or the other. We are in a weak signal area.
Are these things related?
Has the phone become faulty? (Bearing in mind battery life much better with the original one)
Is it just a duff batch of batteries and I should send the battery back for a refund, and get one somewhere else?
Thanks
Mark

Typical behavior for a counterfeit battery but the other symptoms suggest that something got damaged and is stressing the battery. Try re flashing the phone. A sudden loss of power could potentially damage some system files.

Thanks rogem_kk - can I just clarify, when you say "reflashing the phone" do you mean resetting it back to its original state (I'm guessing there's a key sequence you press, I can look in the manual to find that out) or completely reloading the OS?
As regards "sudden loss of power" sadly this happens quite often, because the phone crashes now and again and I have to take the battery off the back and put it back in again. The Android OS seems able to be completely taken down by a failing application (I think Flash movies on web pages are the main culprits) quite readily but I'd got very used to that since my last phone was a Windows Mobile one (the old one not the new one) which had the stability of a damp cardboard box in a strong wind.

I mean wiping it clean and installing the ROM from scratch. Factory reset only removes your data and does not restore/replace system files.

Now may be a great time to flash a custom rom, if it all goes well then do a back up with Nitrality app or similar, while you're at it try out a modem i9000 ZSJPG, you can flash it separately via ClockWorkMod, doubled my battery usage with it, great reception & coverage, that way if you at least get a genuine SGS battery you'll get the most from it.
If you're unsure of flashing you'll need to get reading in the rom section, not too hard to learn.

Many thanks.
Down to 3 hours idle time now - it drops by the day.
Have emailed Samsung on the off-chance they can identify a counterfeit battery from the serial number, so I'll see what they say. Could make for an interesting exchange with Amazon (direct, not via a reseller or third party).
Argos appear to be the "official" resellers for Samsung products in our area but they don't actually sell batteries. As otherwise I'd be tempted to buy one there on the basis that it ought to be genuine, and compare. But haven't rebuilt the phone yet, waiting to see what Samsung come back with.

Hmmm...
"Problems like this, although seemingly severe, can occur when the
Android software on your phone becomes out of date. You can update the
software by simply downloading our Samsung Kies programme. Follow the
link below and choose option ‘save’. Then for safe installation of the
drivers, once save is complete, turn your computer off for a few minutes
and reboot the PC. Once fully loaded again, without opening any
applications on the computer, simply connect your phone to the PC with
the USB lead, and your phone should be automatically set you finish the
installation of Kies. When Kies loads and finds your device, you should
be offered an update that will iron out these issues.
If you require any further assistance, please contact Samsung again and
we will be more than happy to help."

I had one of those so called 'original batties' it was a load of rubbish. Still using original one but its no holding charge for as well after a year of use. Maybe time for a real replacement...

Forgive the curtness of the email, am at work typing one handed while chowing down lunch
First point - you dropped your phone. I know that the new battery went okay for a while but is it possible that the phone itself may have been damaged?
Secondly, Email on Activesync over 3g will absolutely smash the hell out of your battery. Especially if you have push email going. Is it on push or is it set to check every so-and-so amount of time? Too short a period will kill the battery. The "Stock" email app that comes with Gingerbread 2.3.3 or lower seems to be just a big hog over push (for me at least). I also recommend changing the email "Amount To Sync" to a shorter number of days and set the amount of data to a lower value than stock (ie, "Headers Only" or 50k or something) so you download attachments on **your** terms.
Thirdly, you state you're in a poor reception area. This will most definitely affect the battery as the phone on a low signal or zero signal will waste battery trying to reconnect to the tower. Check your "Cell Standby" and see how muck time without connection you have. If it's anything above nothing, it's draining your battery. I recommend flashing a new modem (you'll need to investigate which one is good for your region/country/carrier) through ODIN (or Heimdall). Be careful when doing this and make sure you read up on the hows and what-to-do and what-not-to-do before you do - there is a (small) chance of you killing your phone and I do *not* want you to come back onto this thread and say it blew up (I want you to say "YAY THANKS WOGFELLA" ) Doing this voids your warranty so only do it if you either don't care or you really really want to fix your issue (and by default you don't care)
Fourthly, your wifi coming on and off - go to your Wifi settings, press your menu button and click ... advanced? Can't recall exactly (on ICS now). From there you can set your "Wifi Sleep Policy" to either "Never" or the other option that I can't recall. The default is set to turn the Wifi off when screen is off which of course means you lose your Wifi connection. **For your Email issue, try this first.**
Fifthly, your Wifi signal being weak in your display does not *always* equate to an actual poor connection. Sammy does many great things, but he does mess about a bit with icons and funny business. Check step four above and if you get bad Wifi reception when the phone is off (or while using it) then try messing about with your Router settings and also with the settings on your phone (take notes before doing so, I'm just throwing you ideas here....don't come back to me and ask me how to reset your router settings either!!!)
If that doesn't help then try flashing a custom kernel (kernel controls the Wifi). As above, doing this will void your warranty.
Sixthly, you say that everything was hunky dory and then went haywire. I reckon there may be an app doing funky things.
Try installing CPUSpy from the market and check to ensure your phone is going into decently long periods of "Deep Sleep"
Also, try installing the below app from this thread.
http://forum.xda-developers.com/showthread.php?t=1179809
You're looking for high "Wakelocks" which will impact on your phone being awake instead of...well, asleep...when the screen goes off. Awake phone = cpu processing (even if it's not doing anything) = battery drain. Use Chamonix's recommendations on what is classed as a high amount of wakelock.
Facebook 1.7 for example, keeps the phone awake while checking notifications that just plain ain't there. For me, once I wiped this app, I regained about an extra 2-4 hours per day in use.
Seventhly, look over this thread:
http://forum.xda-developers.com/showthread.php?t=939752
Has a heap of tips that helped me (before I got sick of stock Sammy and jumped to CM7 and then ICS)
Eighthly, and this is one that probably doesn't need to be said - cycle your battery and (controversial) bump charge. I mean, let the battery drain fully. Take the battery out for 5 mins. Put it back in and see if it turns on, and if it does repeat. Then fully charge to 100% and then unplug and plug back in. If your phone is already rooted then you can also wipe Battery Stats from Recovery.
Lastly - have you tried factory resetting your phone? It may wipe whatever it is that's making your phone freak out (if not the email) and you can start again. If you find that the battery goes bananas again after installing that app, you've found your issue.
So...to sum up:
Check your phone contacts.
Check your Wifi sleep policy.
Check your Email update rate.
Check the length of time you have the sync set for,
and the amount of data per email downloading.
Check to see if you are going into deep sleep.
Check to see if there are any apps holding wakelock (and bugger them off)
More extreme:
Factory reset.
Mess with your router settings if your wifi signal is still weak.
Very Extreme.
Flash Modem
Flash Kernel.
One thing not specified: What version Android are you running? SGS comes from Eclair up to (once Cyanogen and TeamHackSung get it rolling properly) Ice Cream Sandwich.
Hopefully *SOMETHING* in the above helps you.
Good luck!

Thanks for taking the time.
Sorted out the Wi-Fi sleep issue, CPU Spy showed the phone was going into deep sleep when idle, so no "smoking gun" discovered with that.
Reset phone, and set it back up again with basic email and no new installed apps. Have left it on default (minimal) donwload settings. Had already got rid of Facebook.
Battery life is better. Have begun reinstalling a few apps now and keeping an eye on it.
Will report back - thanks again all.

No dramas - just be careful as CPU Spy will show length of time in deep sleep but a high proportion of wakelocks won't really be detected and those wakelocks are the ones that smash your battery when sitting "idle"
As you have reset then I think you need to let your battery calibrate first (let it drain fully and recharge fully a few times and that's all you can do if you haven't rooted your phone)

.. one more update..
Battery life is better, but not much better. It still won't last a day without charge even with very light use, 7 hours is about the maximum. I'm certain it used to be better than that when I got it e.g. it survived a whole day on holiday using email and maps quite a bit.
Have changed to 3 from O2 but will have to revert back as 3 doesn't get a signal at all downstairs in some parts of the house. Does mean the phone is going on and off network a lot at the moment.
I reverted to Samsung to tell them their link didn't work and they have sent a link to an authorised dealer for parts if I wanted to buy another battery. I'm all for buying the real thing which is why I bought an (apparently) OE one from Amazon which was about £16 not the £5 that some were.
However this is, er, forty four pounds for a tiny little battery.
http://www.4mysamsung.co.uk/cgi-bin/product.pl?PID=2986318&brand=&model=galaxy s&part=
They also sent links to repair centres.
Now I plugged it into charge earlier, and even after 8 hours, it was dead. Plugged it in again - beeps once as normal - nothing on the display - still not charging. Take battery out, put back in, repeat. Charging now.
Might make you wonder if that part of the phone got damaged e.g. the "socket" where the mini USB thing/charger goes in, but, it's always worked before. It doesn't for instance fail to detect if I plug into the PC and it's never done this before either.
Given how much the battery is and the fact it might be getting to the point of dying altogether I wonder whether to just get a quote for repair and go that way for certainty.
One might have thought it's as simple as: take the thing somewhere and have the battery tested to prove one way or the other.. but I'm really not sure where would do that other than the repair place.
I'd be prepared to try replacing the OS as suggested, but it does remain the fact that the thing worked better when I first got it and even after a complete reset it's still playing up so I feel a sort of mental paralysis over what's best to do now
I'll have a look at the wakelocks thing next when it charges again. If it charges

HTC One M7 Battery Drain and Overheating

I just replaced my aging iphone 4 with an HTC One M7.
So far, I'm loving having an Android phone, and I'm really glad I switched, but I seem to be having a problem with the phone.
It is getting pretty hot and the battery is draining alarmingly fast.
The phone was reset to factory settings when I received it yesterday, and it is the AT&T software version. It is on Android 4.4.2
Although this is my first Android phone, it is not my first Android device (Xperia Play used as a portable emulator, Nvidia Shield, Asus Memo Pad HD7) so I knew the obvious things to try.
The phone feels slightly warm at all times, even when just sitting in my pocket. When I have a CPU-intensive app (youtube for instance) running, the phone gets pretty hot.
I understand that the aluminum chassis transmits heat very efficiently, and that this phone should feel warmer than a plastic phone, so I installed a CPU temperature app.
I'm getting in the high 40's to low 50's (celsius) with no CPU-intensive apps running.
Looking in my running apps, I don't see anything that looks like it is making heavy demands on the CPU.
While at work today, I put it in airplane mode (but kept wifi on) because I don't get a very good signal at work anyway, and I thought this might be causing the battery to drain quickly.
I forgot about this, and so the phone has been in airplane mode since 1pm today (it is now 8:45).
While browsing the internet just now looking for a solution to the problem, I watched as the last 18% of the battery drained down to 1% in around 15 minutes.
This is in airplane mode, with battery saving mode activated, Blinkfeed deactivated, and the screen on minimum brightness.
Does this sound like abnormal behavior?
I need to know fast, because if there is something wrong with the phone, I need to return it without delay.

I just replaced my aging iphone 4 with an HTC One M7.
So far, I'm loving having an Android phone, and I'm really glad I switched, but I seem to be having a problem with the phone.

Is the phone brand new? It runs more the first time you turn it on, I think due to some profiling. If it's still like that the day after turning it on for the first time I'd probably be concerned. It could be due to something you've installed--what have you installed (if you don't mind sharing)?
I've definitely experienced what you're talking about on CyanogenMod, but never that I can recall on the stock ROM. When it happened on CyanogenMod, rebooting generally seemed to fix it.
