Is it normal for bottom of N1 to get hot after installed froyo?

After I installed froyo, every time i use my N1 to surf the net, it get hot and lose battery charge fast. I don't know it is normal or what but with eclair, it was never like that. Maybe it is a bug but i need some suggestion, should i just wait for google officially release froyo or should i call HTC to replace the phone?

if they would even do it.... certainly does not sound normal at all.... can you just go back to 2.1 and see if it is ok?

Dude, I'm so glad you posted that, I have been worried the whole week because I am having the same problem.
I started noticing it a few days ago, but didn't think it was important because it was a specially hot day here is Spain (we reached 38ºC during the afternoon) and imagined electronics would be affected too.
However, it continued during the next days. The antenna cover (where the letters "htc" are written gets mildly warm / extremely hot for no apparent reason, although surprisingly the battery is cool when removed. Last night the phone had a temperature of 40ºC after having been idle all evening and just using the browser for ten minutes.
I also think it can be because of Froyo, since I didn't have this problem before installing it. However, if it turns out it IS a hardware problem, what would happen? Would htc repair my phone, or replace it altogether? I've never had to send a phone back for repair so I wouldn't know.

My nexus that I just bought last night gets a little warm near the bottom. If it hurts to touch it then it's "hot".
I think it's just that you're paying more attention to your phone now that you've modded it. Kinda like when you get a turbo kit installed on your car. You start paying more attention to it. You hear things you've never heard before. Wondering if the turbo kit is causing problems. When in all reality it's been making that noise before the kit you've just noticed it now. Hope that shed's some light on it.

The question is, it gets a little warm when you're doing what and after how long?
I've also considered the possibility that I'm just more aware now, but I really don't think that's the case. The phone is not boiling hot (as in, it hurts to touch it) but it's not something you would fail to notice either. If you grab it in an horizontal position, the heat definitely gives you an uncomfortable sensation.
I used to feel my phone getting hot after using the GPS for a long time, especially under the sun: but not it happens after browsing for 10 minutes at night, that's just ridiculous.

well i guess i wait until official froyo release and see what happen.

i too noticed this problem. especially the rapid battery draining during browsing jumps out to me. when idle or doing something else, battery life is normal. when the processor is intensively used, i believe the battery drains at a disproportional rate to other use.

stock 2.1 and mine gets pretty warm at the bottom of the back when using for extended period or when its charging. Been the case with most of the smartphones I have had so I just wrote it off as normal, even more normal as this is the thinest smartphone I've had. Coming from a Touch Pro2.

Yea, you just described my situation but when I turn my screen brightness to minimum, the rapid battery drain isn't so bad. The battery temperature stay around 97 to 98 F. I hope the official froyo release will fix all this.

Guys, I have installed the latest CM and the heat problem seems to have gone away. I have to keep checking but can you try and see if it works for you too?

This is an issue with Froyo. it doesn't happen with eclair. anyways i noticed it to. The only time it gets hot is when the phone is in the charger and i'm playing with the phone.

Phone heating normal?

Good afternoon all,
I have my Optimus 4x for around 3 days now, the phone is great in general but i noticed when using applications that require more power the phone heats considerably in the part where the LG symbol is located in the back and i think even more in the front where the screen is.
In my case happened with Skype video call (around 20 minutes) and other time playing a game (frontline commando) for 10 minutes, after it becomes normal again, but as i said i think in general when using heavy applications.
Should i worry about this? is this normal? someone else experiencing the same?
As the phone is new i would like to know if is a defect to send it back.
i have software version V10d
Thank you

Its completely normal, the Tegra chipset is just behind the LG logo.
Got to remember there is a quad core and 3d graphics package sat under there

How hot does it go anyway? Is it hot enough make you feel very uncomfortable during a call with the phone next to your face?

I have never had it get hot during a call. Only during something like Dead Trigger.
Even then, it's hot but I can still hold the phone. When you consider skin burns at something like 44 deg C, its not really getting that hot. Especially when you think it's a quad core CPU with no heatsink or ventilation.

Yes i imagined exactly that there would be the processor, of curse is not hot enough to burn but is definitively hot.
My only concern is if in the long term this temperature wont damage the screen or other parts of the phone as for example in my laptop the nvidia video card heated so much that got damaged.
do you have any idea How should be the "normal temperature", is there any app to measure it?
For example does the galaxy 3 gets also hot ?
Sorry for so many questions but im not an expert and i want to be sure i make the right decision
To answer the call question,for me just gets hot as i said when using heavy applications, i would consider just annoying in the case i received a call meantime i played (etc) and the phone was hot but not to the point to say im burning.
Thanks for the previous reply's

Tegra 3 will be shutting down when it reaches about 90_degrees afaik. Don't worry your phone won't die. Only the battery... :-\

Anyone with any update? Its been 5days since I am using p880 and it gets heated up as experienced by other users near LG logo my OS is up to date (v10e)..also I feel battery drain much faster with when heated. Anyone can confirm same?

..cause->effect, not the other way around, and so on.
But generally, a passively cooled device like this /should/ get hot on the outside fairly quickly, instead of containing the heat. On the 4x, it seems like there's a frame on the inside going around the edges that will lead heat there first. Away from the battery, the middle of the screen, that sort of thing.. Ideally that heat would then disperse without ever reaching uncomfortable temperatures. Thought they did pretty well with the 4x. Seen several tablets.. with lower heat signature than a tegra 3 chip.. end up with a few typical spots the heat ends up on the outside (middle of the screen, contact points on sim card, battery, memory card frame, stereo jack.. copper, see?), because the heat is really being contained inside the device much longer than it should.
And then people happily use the device until it breaks. I don't think that's really a problem with the 4x.

I also have this heating problem land looking for a solution. I have p880g (Canadian AWS version) with 10c firmware. It got really hot before I even finished 1 game of The Game of Life. it wasn't skin burning hot, but hot enough to be uncomfortable, similar to a laptop power adaptor. I also think that it was hot enough for the phone to start throttling. The quadrant benchmark I ran while it was hot was lower than the usual.
I don't think that this game is too cpu and gpu intensive that it''ll max out all the LG O4X's hardware. I tried this same game on Motorola defy with cm9 (overclocked to 1ghz) and galaxy tab 10.1 (stock). Both ran it perfectly fine with no heating issues.
I hope someone can help. It makes this phone's Tegra 3 a bit useless if it starts to overheat with less than 15 minutes of playing a game. If this normal and what LG intended, then will likely be my las t LG phone.

Hi guys! I have the same problem - hot phone when I'm plaing some games. My question is: How many percent of battery drain the game for 10 minutes? In my case, for example bad piggies 10 minutes = 10% of battery. I have brightness of display on 0%. So I installed app called PowerTutor (it show you how much energy drain every app) and this app said that bad piggies drain about 600 J for ten minutes.
How about you phone? Thx for answer...

No one answer?

That's ok. All cpu's are active in this game's so heating is normal.

Heating Problem Solution
After searching this forum more I''ve found a solution. The heating problems for the LG O4X is fixed with the v10f and up firmware update. This thread has more information about it.
http://forum.xda-developers.com/showthread.php?t=1974616

So I have v10H (newer than v10F)...
And I dont think that bad piggies are used all 4 cores, because my friend have only one core and he plays this game smoothly.
When you play this game, prosecutes to charge your phone?

Same in my case when playing games (swing shot, death dome..etc) it gets heated a lot and battery drains like passing minutes...
I played dead trigger with NO wifi,no 2G/3G, no nfc, no bluetooh and less then 50% brightness in 30mins more then 50% battery drained. And this happened with every game I tried.
I bought this tegra3 device only for games but this heating and battery draining is making it pretty useless for game.
Any developer can throw some light please.

Unfortunately v10f couldnot resolve my issue and I find v10f/v10g is same as my regions latest v10e.

heating is not a problem its normal because its tegra3 and Quad-core 1.5 GHz Cortex-A9

well, I`m on v20a official software. With v10h I had the issue of overheating when playing a flashout 3d free game - I dont know how, but thermal protection didnt work. After 5 minutes of play, I felt big heat, so I came back to home screen and at this moment my beautifull-brand-new 4XHD went black screen - no buttons worked, even keeping long pressed power...so I took out battery and re-inserted. After start the screen was shaking like it had low-refresh rate applied...I was terrified. I took out the battery for one hour and after this all went to normal. Then I updated by official LG app the software to v20a and checked that phone gets very hot with this app again, but this time I managed to close and uninstall app without burning my new phone...so I gave it a 1-star rating and a comment in google play. Now I installed some app to monitor temperature inside and I see that with nfs:most wanted after 15 minutes of game, it was at 40 degrees (celsius). I checked with other apps and I see this was max and it felt/feels very hot, though this wasnt so hot like I felt with flashout 3d.
My question to all of you 4x HD users is:
can you tell me your temeperatures? Min/max ?
I mean: I have minimum 26/27 celsius (phone in the pocket), with data,bluetooth,nfc on I had about 30 celsius, and maximum 40 celsius (when playing demanding game). Also I saw big increase in temperature outdoors with bright sunlight(I have automatic brightness on all teh time) and while having data,bluetooth,nfc and GPS on.

Atrix HD has been getting HOT lately

I've had this phone for nearly a year (8 gb AT&T version). It is completely stock running Android 4.1. Lately, the phone has been getting extremely hot with even low to moderate use, to the point of having to even stop using it for about 15 to 20 minutes to let it cool down. and the battery seems to be draining a lot quicker than it ever used to be (5 to 6 hours).
When looking at the battery stats, it says that "Android OS" is eating up most of the battery, which seems atypical to me; usually its the screen that eats up most of the battery.
So is there anything I can do to fix this? I know rooting and installing a custom rom would probably help the battery life, but because the device is still under warranty I don't even want to take the chance with it, because my contract expires in October and I don't want anything to happen to my phone in between then.
Like I said, the device is still under warranty so is overheating/lower battery life a plausible reason to get a replaced phone? Also, would I have to go through Motorola to do this or through AT&T? Any insight is greatly appreciated
Thanks!

Battery is a reason and I'm sure it overheating is also so if you do in fact have a warrant and don't want to run a custom rom I'd bring it to att.

I remember when I was on a road trip my HD got extremely heated to the point where the phone itself wouldn't let me do anything (error message saying the phone was overheated) Maybe you life in a hot place? That was my issue at the time. Excessive use?

Have you been using the stock charger?
I agree with echofiive. I've noticed the overheat warning when ambient temperature is very hot.
I'm not sure your condition would warrant a replacement though

I live in New Jersey, so its typical summer weather but I don't think the weather is the cause, it just gets really hot from normal use. I'll give an example, I was sitting in a car a couple days ago (not the driving) and was bored so I decided to play some candy crush. I played for maybe 5-7 minutes until the phone got too hot to even touch. I never got any error messages or anything but I had to put the phone down because it was too hot. I also checked that the battery went down about 5-6 percentage points, just for playing a simple game for 5-7 minutes; candy crush is not a very demanding game like some 3D games are. the same thing happens when i'm just using the phone on facebook/twitter/browser etc. for around 10 straight minutes, I end up having to put the phone down. I was never having this problem before which is why I am concerned and my warranty expires in less than a month so I want to try to get a replacement before the times is up.

Yes I use the stock charger with the stock cable. I occasionally charge on my computer, but thats only once in a while. And even though I haven't gotten a overheat warning yet, I'm sure if I used it for just a little longer than I usually do I could probably get it (and burn my fingers in the process). Wouldn't that warrant a replacement? The phone obviously isnt supposed to get that hot that fast, and the battery isnt supposed to drain that fast as well.

Hmm, the problem seems to be battery related then. Some sort of short between terminals?
I guess you could take it down to the store and explain the situation. They'd probably have to open it up to have a look. I have a feeling that by swapping a new battery it might get fixed.
And as for battery usage, my Android OS is also consuming more battery than the screen so that really isnt a valid indicator. Im not sure exactly how hot your phone is getting because a warning message should pop up on your display.
Let your phone completely discharge till it switches off. Then recharge till it hits 100%
Try this cycle atleast twice and then use it and see how it works out

Yeah I'll definitely try to do a few power cycles. I may be able to get bette battery life that way. Not sure if it will help with the heat but its worth a try. And I will probably still go to AT&T just because I still have warranty so I might as well give it a shot.
Maybe its just too hot for my general comfort, maybe thats normal for a dual core phone, it just seems hotter than usual. I do have a case (that I usually dont use) that I can put on to maybe make the phone not feel as hot while I use it.

[Q] X gets hot while charging? normal?

today is the 4th day with my Moto X...and i'm a little worried about my phone because of my battery issues.
the first day i got my phone, it came with 50% of charge and after some usage it got down to 14% but then, suddenly it dropped to 3%. I have some experience with this issue in my previous android phone, so i just tried a charge cycle and it is pretty much ok now.
BUT THEN
yesterday, my wifi was on and i was charging my phone and it went really hot, according to Antutu Benchmark the temperature was 45.1°C (113.18°F)... i quickly unplugged the phone, and it cooled down within 3 mins..
now today morning,
i made the phone shut down itself by draining its battery, kept on charge, i was not ussing it, only wifi was on and the temprature went 44°C (the charge was around 30-40%).. i left the phone as it is.. and then when the phone charged up to 92% it got better (37°C)
IS THIS ALL NORMAL? DO YOU GUYS FACE THIS?
if not, i'll have to replace this, so please help...
apart from this, i noticed that the device runs for a pretty long time at 1% charge

My phone definitely gets warm when charging. I don't have any apps to tell me the exact temperature, but it doesn't scare me. 45 °C is far below what the electronics can handle, and I wouldn't be concerned, it is well inside normal operating range in my opinion.

My battery is currently 102°f on network surfing the net unplugged. I've seen it as high as 113° and have not had any issues with the battery. I'm still getting 24+ hours between charges.

have you guys seen your X go as hot as 54°C??
its a moth with my Moto X, and it gets hot REALLY EASILY, like do a little bit video recording or take some photo spheres or maybe just play candy crush while charging it goes 48°C
and once... i kept a lot of files for upload on drive.. and it was on charge... nothing else...i kept the phone aside...and within 10mins it was hard to hold.. 54°C
i am seriously worried.. but not willing to go for a replacement, since the service in my country is too bad.. any help? :crying:

Batteries naturally degrade over time. That simply speeds up the process slightly (light tasks) or slightly more (gaming). I've done it on all my 7 smartphones (including my first from 2011) and all the stock OEM batteries are working to this day.
I've even gamed heavily (when I enjoyed those things..) on my S2 i9100 and iphone 4s and both those phones get awesome battery life to this day. The S2 was even left on a shelf in the garage over an entire winter lol.
It's just the word damages could misguide people so I wanted to clarify.
But charging temperature can vary between two identical smartphones. My first iphone 5 was rather cool to the touch while charging where as the warranty replacement I got (dust under the lens, they swapped it for a new one) I got tends to be warm and even slightly uncomfortable to hold while using the device moderately and charging at the same time (same charger). It's just variance in manufacturing. No two processors are alike, no two batteries are alike.

thanks for your reply everyone... i guess i'll have to live with it..
maybe i'll just avoid using my phone while charging..

[Q] Unusual battery spikes in battery stats

I bought my moto x 3 days back and i see that in the battery stats that the discharge values are inaccurate. I could see the charge value going up and down and instead of a steady drop. I dint charge
my phone straight away till 100%. Please help me.

Battery level can go up and down a bit due to phone temperature. If it gets cold...it can lower, and rise when it warms up. That's just one answer.
Anyway, its perfectly normal. Unless its huge ups and downs....that's not normal.

Yes its perfectly normal. It will smooth out a bit over time as the battery gets conditioned.

Sorry for bringing this up, but I'm seeing the same behavior sometimes in my Moto X. And I bought it 3 days ago too. I did a topic yesterday. Its like sometimes (not always) it suddenly rises up like 2 o 3% by itself and then it sudden drop that same amount. I can see these little spikes in the battery stats, however, I noticed it 2 or 3 times. Thing is, I'm quite obsessive so I did see how it sudden went from 50 to 53% and then I saw that 3% drop later on.. Its not that I'm always looking at the battery but I have the numbers in my status bar and I use to check them out (and rememer them) every time i pick up the phone lol.
The temperature is really hot down here right now, maybe that's contributing. I hope after more days of use and charges it gets normal.

itz absolutely fine
I brought this phone about 6 months earlier and i too had the same problem. But it will be fine in few months because i dont get any kind of problem nw days
For instant i could suggest u to try to drain the battery to completely to zero and let it get switch off automatically. Then without switching on charge it to 100% and repeat this 2-3 times, hope it get well soon

Do you have your phone rooted..?? If it is are you using xposed module??
