Lg g4 - heat!

[sswitzer]

I did enjoy the quality of the Advanced calling feature, but my wife is the only other person I call that uses it (and she doesn't care either way), so it wasn't a big loss for me. I haven't had it go crazy with a weak signal since I turned it off, but it's hard to say how may instances I've experienced with low signals since then. I do get a fairly weak signal at home, though.

The thing that has my attention right now is instances where the GPS just keeps searching and searching and searching (which I see thanks to the notification that pops up). Sometimes, it will lock on to my location and other times it will search, search and search again (even though I'm outside and it just found the location a few minutes ago). I have no idea what is making the location requests. The only thing I can find out is that I can force close Android System and that will stop it briefly and then it starts again. I have tried force closing every single app that is listed as requesting location and it doesn't help. I have even tried temporarily uninstalling those apps (that can be unstalled or at least disabled). I have also tried turning off Location History and it still hasn't helped. I just can't figure out why it does this. :/ Even a restart doesn't help. Within a couple minutes of the phone restarting and it will do it again.

Have you tried changing location to battery saving mode? That turns off GPS.

Also try disabling the LG smart home/settings.

Looking at gsam, is there a big battery drain for a particular app at the time?

That occasional drain / heat is not normal. Culprits could be synching or location settings. Check out the access lock stuff in the Common Issues and Solutions sticky. Try out disabling your synching.

Thanks, it never occurred to me that it might be a sync problem. I was so focused on the issue where it gets stuck searching for my location. Really, though, when I does the location thing, it doesn't seem to get too warm.

I'll try disabling syncing the next time it gets warm for no obvious reason.

I've done all this to no effect. GSam says the big drain is Android System whenever this happens.

Unfortunately, Android System is something that other apps use all the time, so for most people Android System is the #1 battery drain.

If it's at the point that it's making you crazy, the next steps are to reboot into Safe Mode to confirm that it's an installed app that is causing the problem (if so, the problem will go away when in Safe Mode), and then to do a Factory Reset. I strongly suspect that the problem is a particular app that you have running, but it may also be some sort of LG or carrier app that is frantically trying to figure out where you're at, hence the "searching, searching, searching". You can also try clearing the phone's cache. Sorry for not being more help, but these sorts of things are hard to track down.

In other news, I started using my old HTC One M7 for a bit and the battery reached 47 degrees

Following up on this somewhat later...

I recently noticed that my seemingly random big battery drains (and temperature increases) liked to occur when I was in a place where my signal might be weaker (such as a large steel building). I would look at GSam and it would say the signal strength was OK at the time of the drain. Puzzling...

What GSam didn't say is that the signal was NOT LTE anymore. I just noticed over the last few days (while I've been in large factory buildings more than usual) that my phone kept getting quite warm at various times. Once again, GSam had nothing useful to say about it. Signal strength was medium on the graph for those instances. But, I happened to see that it was a medium 3G signal, not LTE. Today, it happened again, In a different building, but sure enough, it was on 3G again.

I found a few other threads around the web where people have said their LG G4 has done the same when their phone loses its LTE and steps down to 3G or 1X (for my VZW phone) signals.

The question I'm wondering now is, is this a hardware defect (prompting me to go through the hassle of a warranty claim) or should I expect all LG G4 phones to behave like this on a 3G signal?

I had to replace mine about 3 weeks ago, it started overheating but it was doing so from other issues, like rebooting as soon as it started, and doing it enough to run the battery dead, crashing when i tried to read a text or send one, or use chrome, or the gallery. and after troubleshooting including removing the sd card, changing the battery for the free one i got from lg and had never used, and factory resetting 3 times, i warrantied it for a new problem that came up after the reset, the camera wouldn't turn on no matter what app i tried to use it with

Just following up on this one last time. I just got a warranty replacement for my phone. After all of the futzing around with it, I decided it has to be a hardware problem. So, I contacted VZW and the replaced it under warranty (after making me factory reset it... again). I've had the new phone for about 1/2 a day now. I already notice that the temperature reported by GSam is significantly lower under just about all situations compared to my old phone. For example, when not in use, my old phone would cruise at about 78 degF. This new one holds at about 63 degF. That's a huge difference. Of course, it heats up when you start doing things, but where my old phone would routinely push 100 degF just from reading a web paged, the new phone runs around 88-90 degF doing the same activity. That is pretty clear evidence that the old phone was throwing away energy unnecessarily. One other major change, on the sofware side, is that GSam is showing significant reduction in power usage by "Android System". This is dramatically different from my old phone (and was very frustrating because it seems impossible to diagnose what actual activies are causing such drains under the guise of "Android System"). I suppose that, whatever the hardware problem was, the software was either trying to compensate for the issue or just not running correctly.

So, that concludes this chapter in my Android ownership life. Now I can get back to enjoying this great phone without having to worry about random episodes of battery annihilation.

My phone is currently at 41 degrees Celsius. All I've been doing is browsing the Web. And Facebook. I've tried everything in all the threads. Bit worried about taking it back to the shop as I replaced the nfc sticker with an nfc and wireless charging one on my leather case. Reckon they'd let me get away with it?
