too much heating on the lg g4

hi,

my lg g4 is heating up like crazy, specially on the front side which makes it really difficult to talk. also when the phone is in my pocket for over 3 0 minutes untouched i still feel the heat on my thigh and battery drops by 15-20%..... anyone with any solution to this?
[G4 Q&A, Help & Troubleshooting] hyperxguy:
Comparing between our Note4, G2s and G4s ... the new G4s generate more heat (warm) ... I can barely feel the heat on our G2s & the note4 is cool.

I don't play games at all. I think the G4s get better over time (it was much warmer the 1st day vs. the 2nd ...)

does your phone still heat up OP? about 4th day with mine and im starting to notice it heats up more than usually and the charging is starting to sloow down.

do you have a case on it?

i do, and i feel like the case it has makes it somehow get warmer
[G4 Q&A, Help & Troubleshooting] One Twelve:
What is your screen brightness set to. mention the number ?

Also mention your previous phone and how it performed under similar ambient temperature.

The problem with your post is there is no frame of reference to gauge with.

---------- Post added at 06:07 PM ---------- Previous post was at 06:05 PM ----------

How hot does it get if you just save the recording to internal memory ?

Those temps seem rather high even for a cpu, anyone know what the operating temp range for the cpu are?
[G4 Q&A, Help & Troubleshooting] nipun1110:
I never used screen brightness over 50%. But the thing is the phone gets hot even at idle condition while charging at day time. My previous one....well that one took 6 hours to charge, used to get hot too and I changed it. New one was flawless on first day, but started showing symptoms like that on next day. This is the 3rd day & I am observing.
[G4 Q&A, Help & Troubleshooting] One Twelve:
Try switching it off and then doing the charge. Any difference ?

its normal to get warm during charging but not hot.

your body temp is 37C, to get to 42c during charging is normal. Going above 45c is not.

i did a test with cup of tea and a thermometer. in 45c tea, you cant leave your finger for more than a few seconds. so 45c or above is hot.

FYI, my first and only Windows phone was a fab LG device. It got extremely hot under normal usage.

I returned the phone. ..but the heat issue was later put down to the early Windows mobile O/S.

The G4 does get pretty warm after long screen time on, when the battery, and even the leather, can feel warm to the touch.

This is considered normal ! and not an issue.

None-the-less, if the back cover of your device does feel "hot" to the touch, then that can not be normal.

[G4 Q&A, Help & Troubleshooting] AhmedSH:
Exactly thats what happened with me, after the 5th day started to heat up and charging period is horribly long (more than 4 hours to reach 100%), in the opposite battery getting drained as hell. Not to mention that i did factory reset twice and its useless

already took it to service center and for sure they claimed that nothing is wrong.

i guess we need to reach LG for this issue since the using of Q 808 basically is to eliminate the heating problem.

LG G4 users need your feedback
[G4 Q&A, Help & Troubleshooting] RedOCtobyr:
My phone has been getting warm. And as it warms up, charging slows way down, as documented in another thread:

http://xdaforums.com/g4/help/slow-charging-apparently-related-to-t3134443

But just as a note, CPU-Z appears to have a unit-conversion math error, in the Thermal tab (and perhaps only in the Thermal tab; my Battery tab seems correct). If you set it to display the temperature in C, and note the value, then change it to F, the two numbers are not actually equivalent. The F display is too high.

It was displaying 36C, then 122F when I changed the units. But 36C is 97F, not 122F.

So temperatures that are displayed in F may not be correct. I'm *assuming* that it is correct when displaying in C.

My G4 burned up the first day. I factory defaulted it and set it up fresh, installed Nova Launcher and it hasn't even gotten warm. No issues staying 100% brightness and long periods of usage.

I heard it is the Widgets that are sucking data and burning the phone up.
[G4 Q&A, Help & Troubleshooting] RedOCtobyr:
I have been trying to figure out what app/widget/process/something might be warming my phone up, without success.

Any suggestion on tools to help figure this out?

CPU-Z was showing this morning that my CPU speeds kept staying fairly high (4 cores fairly consistently at 1.2GHz, and the last 2 occasionally jumping to 1.8GHz), which helped suggest that something is staying active. But I have not been successful at figuring out WHAT is causing the problem.

I factory reset mine on the 2nd day I owned it, and am still using the stock launcher.
[G4 Q&A, Help & Troubleshooting] rsbenedict:
I wonder if it's actually the battery. My battery got hot according to various apps, but it was hot higher up on the phone, behind the buttons, not in the battery bay. When I took out the battery, it was warm, but not as hot as the button area. I presume that's where the CPU is.
[G4 Q&A, Help & Troubleshooting] AhmedSH:
yup, and its warmer from the screen upper area as well

Interesting. I had the phone on the charger overnight the last 2 nights, screen off.

Yesterday morning, the battery was 102F when I unplugged it, and the phone was warm around the camera area.

This morning, roughly the same ambient temperature in the house, the battery was around 70F when I unplugged it, and the phone obviously felt cool/normal. The night that it ran warm, I had WiFi off, and the night it stayed cool, I even had WiFi on. I get a good 4G signal at home.

Verizon, no SD card. Some app/process must periodically be "getting stuck" and using a bunch of CPU time, and keeping the phone warm. But I've been unable to figure out what that might be.

Mine yesterday i used for gps on my car and after 20 minutes i had message for high temprature and after that the phone closed. I see the cpu temp and it is only 57 celsious.

Maybe i had all this because inside on my car the temp it was realy high.

Today i try it again but no in front glass of my car. I put them next to the seat and works with temps up to 52. After that i try to capture video and after 6 minutes i had the same message of heating issue and the phone closed again.

I understand the average temp in Greece is high but all this is very strange. You see that normally?

I still have two days to change it but do not know what to do. Never had other heat issue with this phone playing games, watching video or browsing exept this.

Sorry for my English.

First real huge battery glitch for me. My phone froze and I had to force restart it. It was charging fine before the freezing. Afterwards, it won't charge beyond 41%. It's been stuck there for at least 30 minutes and it still says 1 hour 21 minutes until full. I've never seen this before. Temp is running at 96F and it won't register knock code or double tap to unlock at all. Screen is noticeably warmer (though not as hot as my first phone). I am on an ANKER quick charger that usually gets me about 1.5% charge per minute. But now the battery is frozen at 41%. I'm going to restart the phone and see if that fixes it. I am texting on the phone simultaneously, but I've been able to do that before and have the phone charge normally. Very weird.

Update: I restarted the phone and it actually was charging and showed 97% after restart and charged normally thereafter. The touch sensitivity also returned. So not sure what happened. Still running a bit warm at 98F.

One question my friend.

When you are on 33celsius and you try to capture 5 minutes 4k video what temperature you have after that on cpu or general cpuz?

The 4k video it want power and the phone heat up temperature. For me after capture i have on cpu 44-46 with abient temprature 30 celsius.

Maybe for that is only 5 minutes or else the phone will overheat.

If you really needed to do that, and wanted to avoid condensation, put the phone in a sealed plastic bag, then put it in the fridge. When you take it out, leave it in the sealed bag until it comes back up to room temperature, then take it out of the bag. You may get condensation on the outside of the bag at first, but not on the phone itself.

I was reading on Android Central where people are getting exchange devices because of excessive heat. Today on my way home from work I decided to turn on navigation and then I drove straight to the nearest T Mobile store. I handed my phone to the associate and asked her to feel it. She was shocked and wondered what I did to cause that. She offered an exchange but I needed the receipt and box. My current device is only 6 days old.

I took the phone in to do the exchange. The guy that worked with me was rather condescending. He tested the phone on their laptop software and didn't find anything wrong. I didn't feel like unleashing the wrath of God at the time so I walked out on him. I did a factory reset on this thing and didn't allow it to download everything automatically. It seems to be doing a lot better now. For example, I have been using this thing for 2 hours now and the battery has barely dropped when before it would have dropped drastically.
