Battery wont charge past 99% - LG G5 Questions & Answers

So last night I plugged my phone in and noticed it kept charging all night but would never go past 99%...so I did a factory reset and tried to charge it once more and still the same thing...I've tried the factory charger and a different aftermarket one that I only use for emergencies...so im wondering if it's a charger port thing or a battery issue...do you think the battery can be replaced under warranty?

Try discharging it to 50% and recharging it. The newer batteries won't charge to 100% unless they are below at least 85%

This has got to be an Android bug because i have noticed this same thing on 3 of my devices. Lg g5, the Huawei Mate 2, and an Asus Zenfone 2

Charging Time

How long does it take before your batteries are fully charged?
First, need to start by stating it seems the charger that came with my S3 may need replacing, as the phone doesnt charge when I connect it. I connected my Note's charger though and it started charging.
I let my battery drain to 1% and started charging, its been 2 and a half hours and its at 47%.
Does that sound normal? My Note gets fully charged in about 3 and a half hours.

Have you tried the original charger & cable again after you got a little juice in the battery from Note's charger? Also to determine if its charging slowly, were you using the phone for various things while it was charging??? How long has your screen been on while charging, because that is the biggest battery sucker on a Samsung device.
Just tried using the original charger and no luck. Weird thing is the S3 seems to think it.is just connected via USB as the USB connection prompt appears whenever I try to use that charger, but still doesnt charge.
Im using the Note's charger now and it is charging again.
The entire time the phone was sleeping, screen was not on.

Sounds like either a defective charger, or a defective battery/phone. If you have a warranty, I advise exchanging your device through that method.
Thanks went to Samsung and turns out the cable is defective.
How long does it take for your S3s to fully charge coming from little to no charge?

I never leave mine till 1%. Usually at around 20% and it takes 4-5 hours. Is it better to leave till 1%?
Also how fast are you depleting a? Had a galaxy s and a iphone 4 before and the s3 seems too deplete a little faster.

Charging phone does not work.

My phone dropped to 7% battery. I let it charge for an hour with airplane mode on and it was at 4% battery. The orange light was on the whole time meaning it was charging. I then turned it off, took the battery out and it went to 13% battery. Soon it went back to 4%. I let it charge again for 2 hours this time and it hadn't moved at all and was still at 4%. I then swapped the stock battery for one from China. It started with 60% battery and after a half hour of charging it went to 54%. Why does my battery drain while it charges? I don't even use it when it's charging so I have no idea why it's draining. I'm running stock ics but it's rooted with 4ext. Any ideas?
Thanks.

Charge with AC not through an USB plugged to your computer. Your phone is using more battery than the USB port can provide. If you plug it in through the normal AC charger, it should be fine, as it gives out 1.0A, while USB ports typically give out anywhere between 200 to 500mA (at its absolute maximum).
I am using the ac. That message even appears when I use the ac.
Have you tried turning it of and charging?

I have tried that and it only turns on to what the battery was at before. As I typed this I went from 54% to 21% in about 10 minutes. This is really starting to piss me off. My phone cannot hold a charge. My motorola from 8 years ago could at least hold a charge. This is ridiculous. Thanks so far for the help.
Are you using the factory Amaze Cord to charge your phone?
My factory amaze cord stopped charging via ac. I had it plugged into the wall and it would say usb charging so I'm using a different kind of cord. I've never had a problem using my sisters blackberry cord plugged into the usb converter to ac.
Maybe....just maybe...your devices charging port is defected...
I have some charger from China that goes from the wall straight to my phone without using that charging port and it doesn't charge it either.
China should only be used for one thing...Chinese People
I tried another one of my batteries that had a 60% charge. Within 10 minutes the battery was dead. I have it charging and the orange led is flashing. I waited 20 minutes and tried turning it on. After several presses of the power button it finally turns on. As soon as it gets to the home screen the low battery sound beeps and it shuts down. Seriously what am I supposed to do? This is getting ridiculous.
Thanks.
Have you looked into doing a warranty exchange...

I have not. This has only happened 3 times or so since I got it a week or so after launch. I didn't suspect it to be a hardware problem. I think the person who suggested the bad power port was correct because my Chinese charger charged it full perfectly and it's been good. It just has to be held at a certain angle to charge. I'm going to go to Telus and try and get a new power port and see, maybe I could get an exchange. I have it rooted though, so would I have to unroot it get the exchange?
Thanks.
Step one, dim the phones lighting.
Then check to see if there's an app keeping the phone awake causing it to drain battery while charging,
If its not an app keeping it awake then you my friend are one of the unlucky owners of this picky phone...

Serious Battery Charging Issues

From yesterday I have been seeing some major battery charging issues with my S3.
Battery drained in evening, came home and connected it to charger for 3 hours and saw battery was just 8%. I removed the battery and put it back and left it for whole night charging. Woke up and saw (after 8+ hours) 22% charged.
Now that's a serious issue. What else can be done now? Is my adapter not working? or that mini dock? or something else?
Samsung disappointed.
Try reboot. Could be a rogue app constantly pushing your CPU. If it does not charge faster, try shut the phone off at a percentage you know, charge a hour and boot it up. Should have charged at least 40% in that time.

When the battery drained. The phone was switched off. Charged for 3 hours and it was just 8%. And yes, I rebooted my phone twice. and removed the battery too.

Try wiping battery stats in cwm?
or
use a different cable/plug
There are quite a few faulty wall chargers around. Mine was totally dead others work only sometimes... Maybe try charging @pc or with a different adapter.
Due to the software update via Kies, Root access and CWM was lost. Will use a different adapter...
Now it's being charged via my laptop (very slow though) but adapter was not doing anything except just showing the red LED light. :/
I think I have to change the adapter.
It's the adapter which is not working. Charged from Galaxy S2's charger. Have to get it replaced from samsung service center.

Problems with charging (or not charging )

Ok recently i have noticed that sometimes when my phone is plugged in to charge it wont actually charge although the battery has the lightning sign indicating its charging..
example .. two mins ago it was charging on 83% looked again 2 mins late it 80% when it works it works fine , but when it doesn't it can take about 8/9 hours to charge or it will get to say 40% i'll use the phone to update facebook and it will go down 2 or 3 %
also something else that has not happend before but has recently is when i plug phone it betterbattery stats shows a box with dumpsys or sysdump any suggestions
any suggestions
checkrom 5.5 , xxdli2 modem , stock kernel
thanks
I have the same problem
I also had the same problem but I flashed the ARHD JB with siyah 1.6.8 kernel and changed the AC CHARGING to 1200 from stweaks and now my phone charges to 100% from less than 10% in 3 to 4 hours
I have a similar problem but I think my S3 is simply broken. It used to charge fine, now it charges slowly and discharges rapidly. Replacing the battery and doing a complete wipe did not help. More interestingly, I noticed it even discharges when completely turned off, which I consider proof that it must be a hardware issue.
What USB cable are you using?
It seems the phone won't charge when cheap cables are used. Only fancy ones and the ones supplied by Samsung/HTC/Nokia.
I tried 8 cables in total
I'm using all official cables

I have since started using a charger I brought from a market and it works perfect. Go back to the original one and it plays up again

Battery charging during night: 90% max. (Strange)

Hi, I have a strange issue (not very important):
When I charge the phone during the night (6 to 7hrs)
From 40 or 50%, every morning the battery is at 90%.
Not using quick charge during the night.
But during the day in my car or at work quick charge I have
100% with no problems.
Have you got the same issue?
I can't say I have the same issue but out of the blue my phone won't charge past 99%...it just keeps saying it's charging and not getting a full charge...I'm having that issue with any charger I use...think I going to look into at least a battery replacement...

had similar issue using LG G Watch wall charger (700ma output) which charged well any other phone.
G5 instead was everytime charged till 80%.
Instead using LG Nexus 5 wall charger (1200ma) or even iPhone one (1000ma) i got 100%
I think it's maybe a kind of protection with some chargers. I don't know, first phone I have this issue.
And for your 99% I understand that can be boring, it's just 1% but..
I really don't care but it's not normal so may as well get it fixed somehow since it's under warranty...

If you aren't using the charger that comes with the G5 this is your answer. This happens with other phones as well typically the S6.
I use charger that came with my LG G5
You're wrong. I'm using my LG G5 original charger but it charges only to 90%. And this is just my second day owning it. First day it charged to 100%. (Unplugged after reaching 100%)
Something similar happened to me. The phone wouldn't charge past 92% a few times. Then the problem was solved by itself. :/
