Overheating LG G2 D802 - G2 Q&A, Help & Troubleshooting

Hello, I have a problem with my phone for a while, it overheats a lot, and the battery is empty in 1 hour, I noticed that I have also since a problem with the WIFi (no longer works) I replaced the battery , changed rom, always the same, someone would have a solution.
If not how to disable the reception in wifi (hardware) I think my phone is still looking for network and this could explain the overheating and fast emptying of the battery
Thank you for your comments and solutions

Nobody has any suggestions to make to me?

I have faced the same issue before. It seems that it was caused by overheating. There is no way for me to fix the problem. There was a post talking about the overheating issue which caused broken wifi.
You may have a look on the link below. It gives some solutions for repairing the wifi but they don't work for me. Hope it will help you.

The drainage of battery is caused by the wifi keeping switching on and off, which also causing overheat. If the solutions don't work for you, the only way is replacing the motherboard.

mda restarts while im on the web, then says no battery

my mda says that it has like 93% battery life and while im scrolling around on the web after 15 minutes the phone just automatically SHUTS OFF and restarts saying low battery life and then it dies again. whats the deal with that? what do i have to do to fix this? its sooo annoying. any help will be greatly appreciated!
you might be out of RAM..
close some apps that are running..
IE eats up a bunch of RAM..
Looks more like a faulty battery to me! OUT OF RAM or LOW RAM never will give out the message: LOW BATTERY.!
If you have the chance to try another battery (maybe you own a second one or a friend might have the same device) just give it a shot ...
i tried with a different battery. the phone still reboots if your on the phone or interenet for longer than 10-15 mins. whats up with this?
I have EXACTLY the same problem with my phone. This phone is onlt 1 month old and was a replacement for a previous MDA that had SD card problems...
I have the exact same problem. When I don't use WiFi the battery lasts for several days. But when I use Wi-Fi in 10-15 minutes it restarts and shows battery very low.
I have noticed that if I connect and immediately disconnect the charger, it shows that there is a lot of power left in the battery and the phone will actually last a while. It definitely can't charge it so fast, so somehow its getting confused about how much battery is left.
Can anyone help with this, please?
I just did a clean install of the official T-Mobile Rom, and the problem is still there. The phone keeps restarting.
Help please.
right there with you guys. ihave and 8125 and they same thing happens i am just glad i have a spare phone. Bad very BAd.
Guys
Junner2003 is right. The problem is a failed cell in the battery. If you don't put the wizard under any load it will last for a while however as soon as you ask it to do something (like use the internet) it dies real quick.
Get a new battery (not a second hand one that you know nothing about) and the problem will go away. I had the same problem a few months ago and went through all the same issus mentioned on this forum but a new battery solve the issue once and for all.
Thanks for the input, jt_armstrong. I'll replace the battery and report back here. I am thinking I about getting a high capacity one like this one

Hey everyone. jt_armstrong and Junner2003 are right. At least in my case changing the battery seems to have solved the problem.
I got the high capacity one from ebay, and so far it has been working perfectly.

Bettery isue on AT&T Tilt

Helo,
I have AT&T Tilt. It started to report strange problem. It displays a message "To prevent possible data loss, replace or recharge your battery according to the owner's manul" and doesn not see the battery (or its level).
After that phone won't charge until a restart (when for a few moments it recognises battery level).
Did anyone had similar problem, or can help me.
Many thanks.

Could be a problem with the battery. Pretty sure there is a chip in it to report its level

[Q] Uncanny battery life

Hi!
I have been experiencing strange battery issue for some time now. First, I have to point out that I am using the Nexus HD2 ICS ROM with an early May update. So, the problem is that sometimes the battery drain on standby and when using the phone is huge - 70% for 4 hours on standby, with Wi-Fi and 3G turned off. I guessed it was a faulty battery (there was problem during charging as well - if the battery died completely, when inserting the charger, the phone would constantly reboot before reaching the splash screen), so I decided to buy a second battery to replace the old one. There isn't a charging problem anymore, but the battery drain issue sometimes occurs, which makes my phone awfully unreliable. My question is - is that a problem coming from the ROM, or is it a hardware problem (and in such case - how can I fix it?)? Thank you in advance!
P.S. I am using original HTC batteries and chargers, so it's not form faulty production line

Might be the ROM because recently I've been getting extremely inconsistent and unpredictable battery drain on the same ROM. Sometimes its great and I can last a full day with ease, but at other times it barely lasts me a few hours. I think I need to calibrate my battery though (it seems to run out faster at lower percentages) but that's clearly not your issue.
am having the same problem it suck any fix or ill have to flash whit an other rom using miui ics
The reboot problem is caused by Android's bootloader: it can't charge when the phone is off, so it tries to turn itself on.

[Q] Wakelock/Sleep of death (charging and not charging)

My phone has always had this problem, but since Kitkat it seems to be happening more frequently.
It happens when
1. Phone is on charge over night
2. When the phone sits idle for a long period of time.
I've tried several roms/kernels but the problem always persists, I had a nosey around but couldn't find anything in specifics. I tried an that solves the problem when it is on charge well it seems to work it happened a lot less but still happened.
What causes this?
Are there any solid fixes?

making the lower CPU frequency a little higher solves the issue. i've been having this exact same thing.
so instead of setting the minimum CPU freq to 384000, make it a little higher, maybe 486000 or 594000...

Hi, did you manage to fix this by raising the minimum CPU speed? I have the same issue on KitKat 4.4.2
I suspected it could be an app (possibly G+ which is known to drain the battery). Others have suggested it is to do with the wifi policy and the phone locking when the wifi disconnects or reconnects. I am use CATACLYSM ROM now and it seems more prevalent on this than it was on Stock, so I may simply switch back and monitor. Cheers.

Cell standby killing the battery

The image shows the phone was without signal for some time which was about 32% and it will consume power. Don't know the reason behind this, but if phone really had no signal for a long time, then be in another place where there is a good signal and test there. I have seen few times with my old Moto X, that sometimes after using internet via mobile network(without wifi), the connecting would somehow still be open and it would consume battery and the way to fix this, I had to restart the phone.

this is ridiculous ! i never had an issue like this with any of my older phones
best bet do a factory reset and see if it still persists
Same happens to me too. Yesterday I went outside my house and traveling in the city - my battery went from 100% to 43% in 6h40min. I had SOT only 1h. I am wondering if something related to GPS is killing the battery as it always drain very fast if i am moving - but in the other hand it seems that phone radio is draining also the battery a lot. Any advices what could I do?

cell standby is not related to gps and location services i dont think so at least iam pretty sure it is mainly phone network related
Cell standby drains too much battery
I'm using Galaxy S8 Exynos Version (Dual Sim). Facing this cell standby extreme battery drain issue recently. I have tried several options like- reset network settings, restart / power off-on, factory reset and wipe cache partition to see if the problem goes away or not. These things can solve the problem only for 2-3 days. Then after that same cell standby battery drain occurs again. The only thing left is to hard reset. But I don't think this will solve the problem either. These are not the permanent solution. When I first got the phone this problem was not there. For the last 2-3 weeks I have been facing this issue and it is bothering me a lot coz my battery drains too much even when i'm not using my phone. I really need a solid solution for this. Can anybody help? And I hope Samsung will address this issue and solve it asap.
I think cell standby is the worst problem in the S8. It really kills battery. It can make your phone drop 2% per hour.
Same issue here. Didn't have this issue before the latest two updates. Before I had 6-7 SoT and now barely 2-3 hours.
yes, this issue was not pronounced before the latest updates (one or two as mentioned)
Same thing here. After the last update there is a battery problem with standby. Hope they fix it with next release.
same with my s8+ dual exynos
