I did some testing regarding how battery temperature relates to the charge current. My findings are in this thread:

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

As the battery gets warmer, the phone reduces the charging current. From what I saw, when my battery exceeded ~90F, the phone reduced the charge current to my usual 280mA. Below that temperature, I was getting about 600mA. And as the battery cooled further, I got about 1500mA. This is all using the included LG charger and cable, and is measured with the screen turned on, at full brightness.

So if you're in a warm environment, and/or your phone is working hard, you're more likely to experience slow charging.

Good morning,

Same problem here, yesterday the phone was in air plane mode and after almost 4h of charging the phone only was charged about 40%. With a physical USB meter is no charging more than 0'7A and is very hot indeed.

I hope LG give us a solution.

I think the stock charger is faulty/slow

Hi, please help me understand why is my LG G4 charging slow with its stock charger provided in the package which is : 5.0V - 1.8A (Charging time 4hrs 49mins) as its shows in the battery statistics and while I use nokia charger for 930 which is : 5.0 V - 1.5A (its showing 1hr 52mins) - I tried to change the cables thinking maybe the cable has something to do with it - tried it in both 220V-110V outlets - but the situation is the same, my LG charger with high amperes is taking more time then other chargers with low amperes?
[G4 Q&A, Help & Troubleshooting] RedOCtobyr:
Very interesting & informative post, thank you!

How do you shut down the apps? I do Recent Apps (square), Clear All, but I'm not sure I trust that everything is actually closed. I'm not rooted, I'm not sure if there's a way to verify what is still running.

A clarification: Battery Monitor Widget (which I use & like) *can* export to CSV. Click on the gear, then Battery, then Export Battery History.

Wow, I can't believe this issue is still present. I get the occasional email notification about this thread. I returned my g4 just before best buys 14 day return window as I wasn't certain when this would be fixed. I was completely certain that it would have been fixed by now, though. Complete fail by LG. Sorry to you all :/ I have a note 5 now.
[G4 Q&A, Help & Troubleshooting] WooHooT:
Still a problem. I exchanged my 1st G4 to T-Mobile due an unrelated issue thinking I could take care of two birds with one stone. They sent me a new phone and the problem persists. I don't think LG will do much to rectify this problem since the V10 is now rolling out soon (could be wrong) and I'm betting this is a hardware problem (overheating) with software safeguards put in place (to prevent catastrophic problems) so there isn't a fast nor easy solution that LG can deploy short of recalling the phones and giving users new ones. This whole ordeal reminds me of the nVidia Shield Tablet recall with the bad battery. AT least Nvidia did the right thing and recalled their product...

For me, the charging has been very sporadic. Sometimes it charges like it should (less 10% of the time and when the phone is sitting in front of a fan) but most of the time it charges slower than my NOTE 4 ANKER extended battery (which is insane). Sometimes it even LOSES power while its charging via any AC adapter. If it wasn't for this camera, I would have sold the device long ago.

Ridiculously slow charging

My wife has recently hit this issue with a G4 - It worked fine for only a few weeks before developing this problem -

using stock charger , stock cable - even with screen off, all app cache cleared, all running apps cleared - still taking approx. 4 hours to charge from 30%-100%

I have also tried turning the phone off and charging - which doesn't seem to improve things - with Ampere constantly showing between 40 upto 600 usually,m very rarely jumps to 700 or so -

very occasionally I have seen it charging at 1650 - but it stops as soon as the screen is on (one of those days where it's actually charging properly)

somone has tested the phone charging here based on battery temperatures : forums.androidcentral.com/lg-g4/540551-slow-charging-apparently-related-temperature-warm-slow.html

I will test the phone by turning the phone off and then cooling it to see if that fixes the issue

- has anyone tried factory resetting the phone if that fixes the issue ?

[G4 Q&A, Help & Troubleshooting] maydayind:
Asså a fellow imgress player let me enlighten you.

The phone whill charge att 1600ma using screen on.

The problem is often cables.. Cheap cables work for about a week then u get som dropps in amp. As a ingress player u are more likely to burn 10 cables a year.

Try a original lg cable or any other major phone manufacturer brand. Make share it a original and not a China copy. If u still don't get any good charge then try another cable or Powerbank. Still problem. Clean your USB connector or try replacing battry. .. If u are bootloader unlocked u can flash a kernel with fastcharge and the cable don't matter..

The charge current is limited by kernel. The kernel measure the resistant between dsta+ and - in the USB cable. (of course temperature and battery status are a counted for)

Is this bad?

I cant attach a screenshot of my problem but I will try to tabulate it.

Here's the story I accessed the hidden menu via *#546368#*xxx# where xxx is model number and navigated to battery status

I found some interesting facts

Default/Stock Charger and Cable

Current(mA) = -551

Voltage(mV) = 4126

Temp = 30 degrees C

Health = Good

Stock Charger / Different Cable

Current(mA) = -912

Voltage(mV) = 4309

Temp = 31 degrees C

Health = Good

Is it really a negative value for current??

Possible Solution To Slow Charging On LG G4

Try running the battery all the way down and letting it die.

Then charge to 100% while the phone is off, and restart it.

It worked for me, I think it's some sort of calibration issue.

been suffering this for several months now, it comes and goes, it auto fixes for absolutely no reason and starts charging super slow again all of a sudden. besides that my battery now last nothing 10 to 13hs with 3hs SoT, it used to last 20+ hs with more than 4hs SoT, phone has about a year of use, I absolutely hate it, had a G2 before this and was a delight, G4 except for the camera is a pile of garbage, screen ghosting, ultra slow charging issues, incredibly poor battery life after less than a year of use (and is not the battery because I have 3 and they all last the same)
[G4 Q&A, Help & Troubleshooting] biorpg:
My G4 was eating the battery daily with little use, so I did drain it 100%. I made sure it was as drained as could be by pressing the power button to let it come on and say "Battery too low to turn on" over and over. I had to do this like... 100 or more times, but luckily the restaurant I was at was very slow making my food!

It didn't fix my problem right away, which was actually a background process eating the battery, but once I stopped it from running, the battery was back to its brand-new level of performance. I like pulling my phone out at lunch time and seeing 100% still :D

Try draining the battery like suggested above.

All lithium ion batteries respond well to this, or rather respond poorly to being partially drained and partially charged over and over. Fully draining and then fully charging lets the battery recalibrate itself.

my G4 usually charge from 15% to 100% when turned on in a little more than one hour. But a few days ago when I try to charge my phone using my friend's laptop and USB cable it almost didn't charge even 1% after one hour (while I was using phone) and from that time super slow charging problem started for me. Even using stock charger and phone turned off it took about 2.5 hours to charge and if turned on it took more than 4.5 hours to reach 100%

Hello guys, new member here.

So recently I've noticed a bright tiny spot on my Tab Pro 8.4 screen. Not sure if this is what is called a stuck or dead pixel because in my case it does actually change color except with black, other than that it looks like a tiny bright light, like if you held a flash light behind a screen. So my question is will this be a problem later on and I should send it for repair or this is something I can repair myself ? My device is still under Samsung warranty. I tried taking a photo with a real camera but it failed to capture it. Thanks for any help.

Any problem related to repair, you should deal directly with Samsung unless you have warranty cover by BestBuy. All of those guys at BestBuy or Fry's Electronic cannot do any repair related to laptops or tablets, simply they're not trained to fix them, and most important: they don't have any spare parts to replace a defective one. All they can do as a middle man and send it to an authorized service center to have problem fixed. Don't waste your time at BestBuy as these geek squads cannot do any repair related to Samsung tablets.

Well, since the white spot wasn't that big of a deal I was willing to live with it... until another issue started to affect my unit. This time it was what seemed the battery, quick story: once the battery would get hot or fall bellow 40% the unit would fall in a reboot cycle, only way to stop it was to cool down the tablet in front of a fan or plugged it to the charger.
