LG G3 Overheating warning?

[tech_head]

This phone does not get as hot as my GS4.
My GS4 (AMOLED display) would get *HOT* if the screen was on for any length of time.
The G3 stays pretty cool by comparison.

I have seen two reviews already that stated the phone overheated and the phone disabled settings until the phone cooled. This is now my biggest concern of this handset. Can anyone comment on this issue? I am considering this phone for my wife.

I've been using this phone heavily since I got it, I can tell you that over heating is a rare occurrence, hasn't happened to me, and I have 4 other friends that have an LG G3 and they haven't over heated either. I hope your wife enjoys it

Edit* I'm basing that rare claim on the bases of average consumer usage, not AC reader usage.

You're not the only one. My phone heats up really bad. When I record my device in HD my phone peaks around 80-85C, but when I set it in 4K recording it peaks at 94 Celsius. I'm not exaggerating, my phone gets HOT! Yours doesn't seem that bad comparing to mine. I plan on returning mine.

94 C is too hot, if referring to battery temperature . On my note 3 battery, it says not to exceed 60 C/140 F. This is dangerous and I would advise you to discontinue use immediately. As a reference point, Boiling water is 100 C, so 94 C is close.

I think he meant it for the cpu - it gets hot quite often but cools down after immediately.

Heres a question for those who video record and get the warning sign notification.

Are you all recording in the highest mode?

And is your brightness turned up all the way or pretty high?

 

[carney198]

My cpu sits at around 135F With the screen brightness at 20% and general facebook/forums/Internet etc... Is this concerning?

 

[broseph408]

Can I ask how exactly you're measuring this temperature?

Download Cpu temp application on the playstore, (https://forums.androidcentral.com/e.../details?id=com.yanyan.cputemp&token=hKPvTLQb). There's a setting you can have the Celsius appear on the top screen.

Both methods was used: high brightness + video record on HD and 4K. Then I tested out on low brightness on HD and 4K (made a difference, and idles around 70-73C)

Ok cool gives me more of an idea how to not heat it up. I dont think ill use 4K much. HD seems perfectly fine to my eyes since it is just a phone. Has your phone got hot just from basic use?

 

[broseph408]

My phone gets very warm on basic use with high brightness (60-63C) if I were to go on Facebook, Instagram, Reddit, etc; low brightness 0% reduces down to 54-58C when running those apps. If I lower the brightness to 0%, close all the applications in the background and leave it sitting on my desk, doing nothing to it, it's around 49-51C.

Was there a mushroom cloud next to the high temp warning? Good god.

I didn't get a mushroom cloud warning. My phone auto-sets itself to 85% from overheating. Usually the brightness drops down to 90% after overheating, but mine was at 85% instead.

Would you be able to post a picture of these Temps? Getting that hot would most likely cause internal damage and be to hot to hold.

I'd honestly get it replaced.

I was using highest recording mode but the brightness was turned all the way down. I got the message twice.

Personally, I'm not going to trust that app. It says right in the description that if the kernel doesn't support CPU temp reporting ("getting the exact CPU temperature depends on the linux kernel, otherwise it will show you the temperature by algorithm") you're getting a guess.

In 30 seconds it swung from 0 to 75 C. Multiple times. Without getting too scientific, this simply isn't possible without an external force helping to change the temperature. That would either be external cooling and/or heating.

I have access to a FLIR IR gun for measuring temp, and the hottest I could get the skin temp on the G3 was 44.3 C. That's actually really good thermal performance for a phone with such a high-end SOC in it.

Same on my note 3. See it going from 0 C to 75 C. Ambient temp here is on around 78. No way the cpu is 0 C on my phone right now.

With regards to cpu temperature, there is a fail safe in which the cpu will shut down if it gets too hot. I have seen it happen on my surface pro. But before that, on my note 3 it will reduce cpu power, reduce our stop charging, and shut down apps. I have not seen shut down on my note 3 yet.

This.

I believe the app was reporting erroneous information. 75 C would be burning your hand if you were holding it and that was the actual temperature.

I normally don't get a warning, but my G3 does tend to overheat quicker than my dad's GS5

I was about to start a thread on this but saw this...I've been using the paid version of System Panel to watch my battery and cpu temps. Just sitting idle, in my house with medium light, auto brightness at 35%, screen on, no apps running - battery is 31C and cpu is 42-45C. If I use the GPS for even 10 minutes it hits 70+ and shuts down. What would you do? This is my 2nd G3. The first had a bad vibrator mechanism, it just went off randomly.

Going back to what I said about the previous app being used, without explicit support for the temp monitoring apps it's taking a guess.

That being said, if it's really shutting down then you do have a real problem. I would take it in and exchange it if you could. I will try using GPS on mine again today, but even stressing it out pretty bad didn't force it to give me any sort of warnings.
