[Q] Heating up while charging

Does everybody's vibrant heat up like crazy when they are charging their vibrant?

yes I have two of them and they get pretty hot ( you can feel it in the back side underneath speaker)

Mine as well gets hot but it doesnt happen all the time. It's charging right now and it isnt doing it. Weird...

it usually won't get hot unless you're USING it while it's charging.

Mine used to go up to 116 degrees while charging, but them I swapped it out and my new one barely goes past 95

Yes mine gets very hot also. How do you know your phones temperature? Theres a temp guage built into the phone?

Play Sims while charging. That's how I'm planning on keeping warm this winter. Oh wait, Sims keeps crashing now...

Try disabling the Wi-Fi and GPS while charging it....Seems to stay cool when I do this on mine.

When using up a lot of energy and charging at the same time it causes the heat...this is one of the problem with the current battery tech :/..
from experience with other phones..wifi + charging = hot as hell..if you really must use wifi while charging for say tethering then I suggest putting it on a metal surface(which will act as a heatsink in a way) and it won't get hot.

I'm from down south.. And mine sits at 110... seen it at 115 before... Ive never had another phone get as hot..

I noticed this as well too. Seems that it is more noticable if you put in on charging soon after using wifi/gps intensive apps. Maybe they stay on longer when it sees it is on ac power? I even had one point where after over an hour charging there was no noticable gain in battery charge. I imagine it was using so much power that little was left to actually charge the battery. In all cases, a reboot fixed the issue and it charged quickly with little increase in temp.
Kinda remides me of my previous windows mobile phones. Sometimes an app would "hang" even though there was no error message and the app appeared to close down fine, I would notice my battery would be used quickly and the phone would be very warm. Usually it was an app that used wifi or gps that caused the issue. Maybe the app crashed before giving a "release command" or similar to the hardware and it kept on running at full power?

It happened to me twice. My phone went past all of yours. It got to temp of 143F. It was really hot all over the phone. I had to turn it off and take out the battery for it to cool down. It wouldn't even let me charge it cus it was too hot when the phone was off. I woke up to 18% battery charge after 7 hours of charging. It said that the display was using most of the batteries. I believe when you plug in your phone, i noticed a change in the brightness setting and i dont have automatic brightness enable. Now i make sure i fc everything before i charge and the brightness is at 0.

I use battery life from the market, also the phone had a temp gauge but to access it I use the "my device" app from tmobile > storage and battery > battery level
My phone only gets seriously hot, 122 degrees, while using the gps on full brightness

Normal. Remember different phone and different processor .... winter they should be cooler even while charging.

[Q] How hot is too hot for EVO?

I recently have been playing alot of PES11 and about 10 minutes in, my phone heats up to around 106 degrees. After a couple games I let it cool of because I am scared I will fry my phone. Is 100+ degrees hot enought to do damage to my phone? Any insight would be much appreciated!
I am using Myn's Warm 2.2 RLS 5 with Netarchy kernel.

The battery danger zone is 60 deg C +, while most electronic components can exceed that temp. As long as it is not getting too much over 50 deg C, you are all good
(50 deg C = 122 F)

I havent managed to get it that hot yet... sounds like I am good to go. Thanks much good sir!

mine at 117f is that bad im tethering atm of wifi hack

Again, your battery is safe below 140 deg F so once it goes above 122-131 def f (50-55 deg C), then I would let it cool off.
A good idea if its getting to hot, is to make sure the screen is face down so it can ventilate. Don't leave it face up on the bed or anything as that can help heat build up

Cool thanks for the tip

Recently my battery stop working and it use to get pretty hot....think I fried the thing....took it to sprint and was told to purchase the extended one for 60 bucks..... no way I would pay that much.... found one on amazon for 11 bucks....well an OEM standard battery... works so far but still gets hot...think I'm going to buy at least 4 more just in case.... I do use USB tethering alot so mabe that did it...

Sometimes mine would just randomly get hot (real hot) while charging, and the light will start flashing from orange to green, I assume its a warning light and the phone wont charge until its cooled off. Even across multiple ROMs and kernels, I never figured out why it does it.

phatmanxxl do you know what temperature your phone was getting up to? I use system widget to see what temperature my phone is at. Ive never seen or heard of the notification light flashing

probably using that particular GPS software, not just GPS antenna by itself?
does it heat up if you just display GMaps with your location, without doing anything heavy in GMaps? Because I did not notice that much heat coming from using light GPS apps. Gaming - yes, some of those games are killers.

I am using Navigon software. I played Angry Birth and the same,phone was hot after 5min. I know is normal that phone is warm, but this is not warm,but hot.Galaxy S was cold compare to S II.

Of course it's NOT normal. Might be normal for SGS2 but not for others. as I've said on another thread, Navigating with GPS driving it got to 60C, you could slowly cook an egg at 60C.

Mine doesn't get especially warm, It gets well 4-5 degrees warmer when I browse the web or watch HD movies

It's think it's high screen brightness in combination with SW (high CPU load)!
Mine is never warm if brightness is kept below 50%

My screen brightnes is 0%. It is hot at the top where is CPU I gues.

How many degrees celsius is taken as very hot on the Galaxy S II?.
I was overclocking my Galaxy S II earlier and my temprature was up to 46 degrees celsius when i was running a stress test on the phone.
So i just stopped my stress test of the phone then.

How did you measure temperature?I have just battery temp. it is 42.

You can download the same stress test program as i'm using from Android Market. It's called StabilityTest v1.5.
it will test your CPU's on your Galaxy S II if you are overclocking it. But you can check the temprature even if you aren't overclocking.

the temp rise is sort of random, i can play games for hours (and its 26C here) with brightness on auto and so on, it doesnt get hot
then suddenly, it does, sometimes even when im not doing much
didnt get the time to pin point w/e thing creates that behavior
(and when i say hot ofc im talking of very very hot - which is what everyone talks about imo)
killall or restart and its good to go til it happens again

I'm running that app now. I wanted to get an idea of temperatures at stock before undervolting/clocking so I could see how much difference it made. But the phone is seriously hot to the touch, enough to be worrying about. The app's reporting 50C after 37min but it feels hotter than that to me.
Some components are designed to run hot. For example I have an ATI 4850 that happily runs 70+C at idle is rated for up to 120C. But I'm worried even if the exynos can handle these temps what about the other components? The top of the screen feels even hotter back. Could this cause damage to the display for example?
This is my first smart phone but having that much heat in such a tightly packed device seems like a recipe for failure.

You will find temps of 50 deg centigrade and more when using all resources of SGS II (e.g. nav with wikitude drive = camera on) and phone attached to car screen on a sunny hot day.
This is normal!
Touch a nav-device in action and You will find it glowing ......
But contrary to HTC HD 2 SGS II does not freeze or crash at that point.
Leave a device switched off in direct sunlight in a car and it will get hot too, but still it will work .....

my phone was getting extremely hot when benchmarking etc, this was default clock and voltages.
the phone reported it was reaching 50 degrees. thought this was "normal". this was on the firmware the phone was running outta the box.
flashed latest firmware and have since messed about with overclocking, @ 1650 my phone never got as hot as it did stock.
so if you have not done it, flash the latest FW...

So your cpu is not 1200 but 1650mHz now?

Been running tons of different ROMs on tons of different Android devices, and every once in a while there is a particular combo that gets tremendously hot.
Once had my N1 get so hot while using Co-Pilot Live and Spotify while plugged into a car charger, that it turned off and wouldn't come on again for some 5-10 minutes.. Definitely worrying.. Switched ROMs and never saw the problem again.

Atrix tends to run hot quickly

I'm running CM 7.2.0 with faux's 1GHz 0.2.4 kernel underclocked to 912 MHz (though I've had this with all CM roms and kernels) and after more than a minute of screen time my Atrix's CPU tends to exceed 50 degrees Celsius while the battery gets to around 40 degrees Celsius (this is recorded using setCPU). This happens most with apps like BaconReader or Facebook but has happened with others too.
I refuse to play games on my phone because it seems to nearly overheat while I'm playing any game.
When the phone starts to get hot, the battery drains faster (like 1% every 2-3 minutes).
Is there something I can do to fix this, or is this a common problem that I shouldn't mind?
Has anyone else experienced similar temperature issues?

Indeed my friend, its the Tegra 2 chipset, in fact, most of nVidia hardware tend to overheat, including Tegra 3 and PC/Laptops Video Hardware.

Probably you have some rogue apps running in the background. You could try the GSAM battery monitor. It shows which app using the most battery and waking your phone.

It is getting hot because it is under a load. Not the phones fault. It is something you added. I had a "bad" app that looped and kept trying to write to cache. I couldn't figure it out till I used logcat. This phone still kicks ass, even if it does have Tegra II.
Also, BetterBatteryStats is free to xda users.

i know exactly what you're talking about, i jumped around all them roms based off of CM7 and CM9, tried different kernels, I did like Clemsyn's 1.0GHz enhanced kernel. In the end, try the rom in my sig, its based off CM7.2 stable, i **** you not my friend, first time ever I have enjoyed more than 24 hours of phone use on a single battery charge, phone never gets anywhere remotely close to being as hot as it used to, something about this build, i dont know but my battery lasts now and phone doesn't cook in my pocket after a phone call, check out log i have of how much battery life I got from 1 full charge
try flashing Jug's battery fix through CWM, it slows down the drain of the battery to a noticeable level where you can see it really does work and helps keep the battery from being pissed away after 2 phone calls

This is happening to me as well and only with this Rom have I had this issue. I guess I'll try changing roms and see if that fixes things.

i am using epsilon project v5 and problem solved

[Q] LG G2 Operating Temperatures

Ok, I searched the forum about this topic and didn't really find anything answering my questions. I'm currently coming from a Droid RAZR and it ran hot to say the least. I can't get a straight answer on this phone's operating temperatures and I'm trying to determine whether to put a thick case on or not(with almost no bezel, I'm paranoid it will break on first drop). From what I've read, about 60% of people aren't reporting very much heat. The other 40% say there is a huge problem and most have had to replace their phones thinking it was a defect.
When it came to my RAZR, at rest with a case on, battery temperature would sit at just under 87 F. Under heavy use, I've hit over 124 F. Without a case, 83 F, the highest I've hit is just under 117 F. Extremely significant when you can't remove the battery and swap it out. I believe that it led to it's premature failure. I want to avoid that with this phone.
Is anybody keeping track of their phone and battery temperatures?
What apps and/or widgits do you use?
What is the normal at rest temperature?
What is the heavy use temperature?
Thanks everyone. My phone gets here in a few days and I want to be ready with a case.

I don't keep track of it. However this phone does get really hot (uncomfortable to hold) when playing games. With Tpu cases this was less noticeable. But lately I installed skinomi stickers for back protector, and it always bother me when it gets hot this way.
That being said, normal uses such as Internet, music, YouTube, xda, camera.... The phone only becomes slightly warm.
-LG G2

I keep wondering why no one makes cases that help dissipate heat, for how hot modern phones get! If anything, most cases insulate the phone and make them get even hotter!

Admittedly, I'm not a gamer but the only times I've felt the device get hot enough to register with the Incipio Feather case were: 1) after a wipe/flash, and all my apps were downloading again from the Play Store and 2) when wiping and the device was plugged into the wall charger (CPU temp was around 100 degrees) - other than these 2 instances, I've never felt heat thru my Feather case.

Honestly i just replaced my phone due to overheating issues. It would literally shut down or restart just running the camera for too long. After reading some other reports in the forums I decided to send it in and get a replacement. My new one came in yesterday and absolutely no overheating issues. Even can run antutu without a reboot (my other G2 would reboot about 14% in). So from my experience there was a batch that had some thermal issues... I got mine the first day it came out.

Does anybody know if we can track manufacture/release date using the serial numbers?

I am using this case full time: http://goo.gl/0u05G5
I use Battery and CPU-Z to check battery temps. Even with over an hour of straight gaming, I have yet to see it get above 98F. I constanty run the screen at 80% brightness as well, as that can be a contributing factor. The games I have played this long with are Riptide GP and Madden 25.
You really cant feel any heat through this case, and hand temps are too subjective anyway.

i wonder what the case would look like if it was made for dissapating heat.. probably has a lot of thermal pipelines built in that would be awesome..

One thing I've noticed from people's screenshots is that the screen doesn't use that much battery. My RAZR would sometimes draw 46%. I'm sure that also contributed to the heat. smh.

I'm currently in the design step of a case that uses tubing to disperse heat at the top corners of the phone to cool it down and keep heat away from the hand.
If you'd like to give input shoot me a pm and we can discuss it further.
OnT: I very rarely pass 24c on mine, then again I never game on my phone either. Highest I've hit was 42c during some testing.

Are you guys talking about battery temps or cpu temps?
Get the app CpuTemp from play store, it overlays cpu temp while you're doing whatever, enable only the top two options, enable overlay and start on boot.
Then get stability test app and run the first option at top, classic test.
Then report back here with your temp after you do the stress test for about 27 seconds. I hit 66c after 27 seconds.
Curious to see what everyone else hits.

My G2 gets also around 55°C when using the phone normally (youtube, browser, etc.) and over 67-68°C while gaming. I think this is normal for a high frequency 4 cores CPU. Right?

Hey, I received my LG G2 yesterday and i've been experiencing cpu temperatures of:
42-48C being idle
52-59C during browsing, facebook, viber etc
62-64C when on youtube (after the first 5 seconds)
65C when on gps
As for the stress test after 1:20 and up to 20:00 it was around 72-74 C
The phone feels hot all the time though with no apparent reason.
Screen brightness is set to 30% all the time, 3g connection is off and I only keep Wi-fi on. I even tried turning off features like gestures, I don't know if it is of any relevance.
Of course I haven't trying gaming yet, since I'm not really interested in it, but I want my smartphone to be functional without burning up.
Should I return it and ask for a replacement? Or is it an issue with LG G2 or Snapdragon 800 generally? Will it be a waste of time?
