    Love my G4, but I am wondering if anyone else is having the same issue. When I'm using Twitter, Instagram, browsing the internet my G4 gets noticeably warm. It's almost borderline hot. It's not like an hour straight of use either, more like 5 minute of messing around. This is my 2nd phone that has done it. I returned the first one I got that I preordered, so I thought it might be a buggy early device. My first phone was awesome for the first week or so then this started happening. The battery life was amazing, but when the heating issues started battery life suffered too. Anyone else experiencing this?

    Not that it fixes it entirely, but have you tried Lux? http://forums.androidcentral.com/lg-...rightness.html

    I've found that screen brightness and the heat felt by your fingers on the screen are directly correlated; Lux does a great job of managing that brightness so that the phone is still very usable but not as prone to heating. I've used it for a few days and a) I've found my batter performance improving, and b) I don't get that "hot" feeling as often.

    Would you happen to be on Verizon? and how is your coverage? The only reason, when I had the Turbo Verizons coverage went in the bucket, don't know why. Then on 2 bars the turbo was overheating a lot. Imo, I think it kept searching for towers causing the overheating. Now with the LG G4 (on AT&T) no problems. But I have excellent 4-5 bars coverage and just running 4G, not LTE.

    Yup I have to mobile and the only difference is in my first g4 I experienced over heating right out of the box, so I retired that and got a new one and it's the same, check out my forum explaining my experiences and also everyone please try to spread the word to LG, it's a serious issue plaguing a pristine device, we gotta fix it asap, both of my LG g4s got scorching and i did resets have good signal blah blah blah

    What would be considered overheating temp wise? My phone being used in the sun will hit around 45-47 degrees Celsius. It's warm but not hot or uncomfortable.

    Do you get the overheat warning? Does your screen automatically dim due to overheat?

    Never. Just didn't know what temp is borderline overheating.

    Every phone I've ever had gets about the same temp once in awhile, androids and apples.

    Difficult to say what temp is normal and what is defective. Do you have any apps installed that provides battery temp?

    My G4 doesn't get hot. Warm at times, but never hot.

    Same here, never hot. Warm if I'm using Google maps.

    It gets hot and so does the back around the volume buttons. Very noticeable in the hand to the point I put it down. I had the LG G2 and I could use it for 30 mins straight and the screen and back never got hot. I returned it and got a new one. This is my 3rd one. Phone shouldn't be doing that. Bro in law has the Nexus 6 and uses the crap out of it and it and it doesn't get hot. Hopefully the 3rd times the charm.

    I've spent quite a bit of time using my phone in the last couple of days, and I have a few thoughts on the heating issue:

    • For me, the heating is not the screen itself, as I've experienced the heating (temperatures in excess of 40c/104f) with the brightness below 50% using Lux.
    • I can say for sure that the phone gets a lot hotter when using LTE, rather than WIFI.
    • I suspect that people not having this issue with LTE maybe have carriers or tower support better than others.
    • I've been using Location "Battery saving Network Only", but I've now switched to Location "Device sensors only GPS"... I think, if I'm right that this will help.


    My theory, based on what I'm seeing through GSam Battery Monitor, is that when I'm in certain LTE areas the Google services are constantly using the network to establish my location. When on WIFI, even in hot rooms, my phone does not heat up at all. (This theory is also backed up by at least a couple people writing that their phones heat up badly when using navigation.)

    I'm not about to close off location services entirely, because I like Google's location-specific content and help.

    I will update this post later this afternoon -- I'll go back out to the same spot I was just at, but with Location set to use GPS only -- letting you know how well my theory worked.

    I should also note that these last 2 days I've been using my plastic back and Spigen neo-hybrid case rather than the black leather back (I wanted to see how it "feels" in my hand) -- and this may actually be affecting the heating issue, as the heat is perhaps not as able to easily dissipate. If my GPS vs LTE experiment doesn't work, I'll try switching back to the leather back tomorrow to see if that makes a difference.

    My G4 (Verizon) gets pretty warm too with little use, especially browsing. Be curious to see the results of the GPS vs LTE experiment

    The experiment failed

    Going to the same spot, with Location set to "GPS only" did not help at all. Using GSam I can see the temperature chart take nearly an identical spike.

    My next experiment will focus on ambient temperature: the spot where I was testing was outside in my vehicle, and it's gotta be mid-30c in there... now I'm back in my cool office, so I'll turn off WIFI and see how things go.
