Rooted H910, running de-bloated stock image
Last week, while reading news sites in a lobby, my phone got extremely hot. Also, battery percentage dropped like a rock - like from 70% to 35% in less than 10 minutes.
I shut the phone down, pulled the battery, and allowed to cool.
On reboot, I went through the Apps list, and Force Stopped everything - even disabling Chrome.
When plugged into my travel charger (QC 3.0), the phone reported that it was "charging slowly - use the charger and cable provided with the phone".
Charge rate was agonizingly slow. May 2% in 10 minutes.
Later, I tried the QC 3.0 in my vehicle, and still later I tried the other QC chargers and Fast chargers I have at my house.
In all cases, it reported it was charging slowly.
It was, however, still charging - albeit very slowly.
I dug out my factory LG charger and cable. Same result.
In fact with the phone off, it reports the factory charger and cable are incompatible with the phone.
[see image 1]
I swapped my battery to another LG V20 phone. The battery charged normally in the other phone.
My phone still charged slowly with the other battery.
Over the weekend, I tried Clearing Cache / Dalvic.
On reboot from that, it would no longer charge. It still reported charging slowly, but battery percent would drop while plugged in.
Per this thread, I tried Doing Port / Battery / Charge Tests.
[see images 2 & 3]
No improvement. Battery level still declines while plugged in.
If I start with a fully charged battery, battery usage appears normal.
Anything other suggestions to try before calling LG?

I left my phone charging overnight via the wall charger. Battery registered at 1% when I started the charge.
When I woke up this morning I had a large low battery icon on the screen and the phone won't turn on. I disconnected the charge, tried charging with another charger but everytime it shows the SAMSUNG logo, then the large low battery icon.
I tried removing the battery, cleaning the charger port terminals, swapped out different USB cords, everything but a hard reset.
No matter what I do the phone will not start up.
Has anyone experienced this before, or possibly no how to resolve it?

Happened to me several times (on both my focuses Rogers and AT&T), and I came to the conclusion it's a bug somewhere in the phone or the battery. I'm not sure exactly where the problem is (software, hardware) but I can tell you how I fixed it.
What happens is, the battery is almost depleted, it actually is 1%. The phone incorrectly reads that thinks it's charged fully and doesn't allow further charging the battery. So, you're not able to charge the battery correctly.
Now, as I previously stated in some other posts, I recommend having a standalone charger (Samsung i9000 ones are compatible are very cheap) as well as a secondary battery. The depleted battery gets charged fine in the standalone charger and when it passes 5% charge, it can be charged fine (again) in the phone.
This doesn't happen often, I believe it happened 5 times in more than 300 charging cycles (2 phones x 150 charges, I have them for over a year) so it's not that common.
I also found that it *may* work if you charge the battery in another phone.
As a general thumb rule, it's important not to leave the battery to completely discharge, and connect the charger/usb when it reaches about 40% (when you can, ofc). Please refer to my post here to see how you can preserve battery life.
Today my phone ran down to 0% and it shut down. When I got home I plugged the charger in at around 5pm. Now almost 7 hours later it is still not fully charged. This has never happened before.
Do you know what could be causing it to take so long?
It is plugged in to the wall.
Thanks.
either the phone is not charging at full rate or is discharging very fast. I would try to charge with phone being off, monitor battery discharge during day especially in IDLE and take it from there. You can also download program that shows charging rate.
Solved. The surgery went fine, actually just unplug/replug the battery
and now tablet is charging fine, but only when on. If I turn it off and plug the power cable
I have the onscreen b&w animation of a charging battery but not even 1% increase over the night.
Might consider finding a replacement sooner or later.

Hi every body
My nexus behaves strangely regarding battery charging, I've tried different cables/chargers same result. I've emptied cache, no result.
Actually here's where I am: When the nexus is plugged with original cable+charger, Battery Monitor says plugged, discharging.
The flow shows a negative mA value. I tried charging the tablet while it's turned off, full night.
Sometimes I managed to get a full charge, sometimes only 5% increase during the whole night.
The usb port seems ok, I can plug it on a computer, copy files both ways, speed is ok. But still no charging.
I've read lots of forum posts concerning battery problems with nexus7, my understanding is that I'm facing
a hardware problem, not software. I have to open it and clean/check the link beetween usb port and the battery charging circuit.
Is there something else I can try before trying surgery?
thx
So I let the phone get below 15% the other day and I plugged it into a charger from an older samsung device and continued browsing. Before I knew it the phone was at 0% and it just shut down. While still plugged in, the phone made a few attempts to boot up but at the end I had to get the battery out. After getting the battery in and plugging in the charger again the phone didn't show any signs of life. Like I hard bricked it. After a few desperate attempts the screen flashed and a few minutes later the phone booted up like it normally would (This happened while it was still plugged in). Now it just won't charge as quickly even with the fast charger. The phone normally gets pretty hot while charging, now it just stays cold.
NOTE: I had it charging trough the night with the old charger but it didn't go over 15%.
I am running Ressurection remix 20150714.
I think it's got something to do with the hardware, and if it does, would the warranty fix this?

That's really not normal if your phone don't get hot while charging
Try a different cable (maybe it charging too slow), buy a new charger or charge your phone on PC. Check if an app use much battery/CPU and check if the battery is swollen or try an another battery. Update your ROM version maybe it's a software bug or reflash it. If nothing solve the problem then maybe you need to clear the usb socket of your phone or it's maybe damanged . Be careful if you clear the usb socket!
Sorry for too much maybe's
Good luck :highfive:
I checked the port, it's pretty nasty but I doubt that's the problem. I'll try and clean it up with a toothpick or something.
Checked the CPU usage and apps and it all seems normal.
I'm not home currently, but I'll do a full reset and roll back to cm11 when I get back.
I've used a travel charger from an older device, an Alcatel charger which actually charged my phone and my factory charger. The factory charger works best for now but it still takes like 5 hours to charge. The phone took less than 2 hours before...
Anyway thanks for the help so far, I really appreciate it.
How much mA you get while charging with the original one? Check it via Gsam battery app
Downloaded it, here's what I got.
Gsam is alternative of Bbs, but with better gui. Look at my ss - I can saw mA of discharge and charge the battery. With stock battery Ive got around 750mA
Yesterday for whole night i kept the mobile for charging and it showed 8% charged i thought it charged up and removed the socket before I knew it the phone was at 0% and it just shut down. While still plugged in, the phone made a few attempts to boot up but at the end I had to get the battery out. After getting the battery in and plugging in the charger again the phone didn't show any signs of life. Like I hard bricked it. After a few desperate attempts the screen flashed and a few minutes later the phone showed the sign of charging but it ended up (This happened while it was still plugged in). Now it just won't charge as quickly even with the fast charger and it wont shows any sign of life.
NOTE: I charged for whole night but is charged to only 8%
Everytime I plug in my device and see how much it's charging by, the charge speed is crazy, from 300-1600mA, and it often stays around where it starts. I used to get about 1900mA often (like, a few hours ago at 80% battery), but now I'm getting that less and less (at 50% battery). I'm running Marshmallow 6.0.1.
okay so I swapped it with another charger I had which is the exact same model and it works absolutely great, charging at 1900mA 80% of the time.
the hell?
edit: this may not be it, it still seems to be pretty variable, just less so
I have a similar issue. But it happens only when I plug in my device while it is booting.
For some reason, during the booting process, the charging current is lower.
I have 2 batteries and have to cycle charge them.
