[Q] LG G4 Charging Very Slowly

Hi, I just got an LG G4 yesterday. Charging using stock charger, or any other charger I had no problems with S3 before, is really slow. As in obviously slow. The unit is estimating 3-4 hours to charge 30%-40% of battery. Once it took around 20-30 minutes to just charge 5% of battery.
Using Ampere app it is showing on average just 270mah charge. Sometimes it registers 1660mah, then it drops down significantly and settles with 270mah.
Using the dual sim model if that's any help.
Is this a new battery thing? Should I insist to have the unit (or the battery) replaced? Is this a hardware or a software issue? Even if i insist to have this replaced I want to be able to explain that this is a factory defect.

Same problem here..
Really annoying.

Same here, I think it charges at full speed when the screen is off...
I got myself a QC2.0 charger and its doing exactly the same.
It does appear to charge faster with it while the screen is off but I'm wondering if there is an update to the device that needs to be done to fully support QC2.0

i've buy an Aukey Turbo Charger Adapter.
Then my G4 has fast charging more about 75%

I've seen the same thing happen on mine. Highest current I've seen was 1650 mah. And that's with the screen off. Leaving the screen on it reduces to 270 mah

I had the same problem but it stopped after about week. Now it charges quite quickly and that's not with the fastcharge that isn't too impressive.

Same issue. Charging went from 2% to 46% in about 3.5 hours and it says it's still another 4 hours before it completes charging. Totally annoying.

i using the Aukey Turbo Charger and get around 1%-1.5% every min i have done 30%-70% in like 40min

I have a HTC quick charger that I used with my M8. It works well with the G4. With the screen off I have had nearly 2 A charging. It is much less when the screen is on.

Just got my G4 and it's doing the same thing.

are you using the screen while its charging tho? how many times have you charged it already since you got it?

my post was made during 2nd ever charging. i did turn on screen occasionally, but not like it was on all the time.
last night charge was shorter - around 5.5 hours.

This is really annoying trying to stream music and navigation sometimes losses a charge. With nexus 5 I usually gained 30 plus percent on my way to work on 40 ish minutes with car charger.

It "might" be a software limitation, to avoid pushing the battery too hard in its early cycles. Same as a brand new car, they usually tell you not to drive too fast for the motor to actually run with optimal parameters.

I am also experiencing the same. I am getting 640mA. It is really frustrating. Yesterday I connected the phone with the provided cable with G4 with my laptop. And i was using the phone, not heavy using. And actually the battery was draining, rather than charging. I got so frustrated. I found the phone actually charges better while staying idle & screen off, but not very promising.

Yep, add me to that list too. T-Mobile G4 with screen off and no use because I'm driving almost all day just to see a 5-10% more charge after driving almost 2 hours. The original charger behaves the same way too. The only fix I've found is to turn the phone off and charge it. It charges really fast that way only.

Charged mine from 2 to 100% in under 2 hours with my note 4 charger

@fatboypup does this also work with screen on? Imagine using gmaps in the car, screen and gps active - it would be a pity if the g4 lost power in such a situation when on the car charger

As I noted above it is an issue with cars too. I'm lucky to gain 5 to 10 percent with navigation and streaming music in 45 mins. The same situation with nexus was over 30%.

Does this behavior stay or is it only for the first charges? Is there anyone who has no slow charging with screen on? Is the g4 gaining at least some percent when navigating with gmaps?

Charging during night and go below 15% ?

Hello,
I was wondering who is charging during the night and who is going also below 15% battery ?

I was having this problem when not using the included charger.
It seems that the phone actually requires to be quick charged (8V 2A) up to 65% or so and will then switch to the usual 5V 2A mode when it's reached this point.
As a result when I was using a regular charger (Nexus 7 charger, 5V 2A) the phone would "charge" but would actually slowly lose battery power during the night.

Gotta watch out for specific usb cables or charger adapters that don't provide enough power (as mentioned above).

I have 2 Nexus 7 FHD (2013) tablets and my Zenfone2 has exactly the same charger, 5.2V 1.35A
A standard cellphone charger is 5V and about 700-800mA.

I turned on Airplane mode and power saver while using a regular 5V Charger, and it was able to charge over night.....just not fully.

I thought I was the only one with this issue. Everything works fine with the included charger but when using my charger from my Nexus 4, it would charge a bit then at times start losing battery. I've used a friend's Nexus 5 charger and it has been hit and miss...sometimes it charges all the way sometimes it charges a bit and then starts losing battery.

Im also using ipad 2 charger..works well as a normal charger for zenfone 2. Especially if your gaming and charging same time..mine does not over heat..but dont recommend to do it always

In fact my question was more about who is charging all night their phones and also who is using his phone when the battery is lower than 15%.
Happy to see some others bugs on the ZenFone 2

Slow Charging Issues

For the past few days, I've noticed very slow charging on my Pixel even if it says "Charging Rapidly". However it would say it will take around 3 hours to fully charge. When fast charging works, usually clocks at 1 hour and 30 minutes.
I really don't know what can be causing the issue. It's the original charger, and cable. Normally removing the cable and putting it again would fix the issue but it's becoming a common thing for it to take 3 hours.
I remember a similar issue on my Nexus 9 and cleaning the cache would completely fix the issue, but the Pixel XL is missing the Wipe Cache option in the recovery.
Any similar experiences?

On the OEM included charger?

Yup.

Could try a factory reset.. probably the only software related solution. I can't remember, but Chainfire may have said that the cache.img was one of the things that got removed in 7.1 so I don't even know if you could wipe it if you wanted to. You could also hit up Google support... maybe they'll send you a new charger to try. Make sure you're using the OEM cable too, at least for now, until you figure it out.

I had this exact issue with mine, factory reset / charging in safe mode didn't work.
Turned out to be a faulty usb cable but Google insisted on replacing the entire package (handset etc) Replacement works fine

Well, thanks for the heads up! What sucks though is that it's type C to type C, I have some Type C to regular USB, I guess I'd have to buy one.

If it makes you feel any better, Google exchange process is amazing.
Raised the return on mine about 4pm and the replacement was on my desk 9am the next morning, they also give you 14 days to send your old one back so you're it without a phone.

I use ampere to see what the charging rate is and I don't feel like the fast charge is that fast.... My 6p charged at a faster rate and my pixel charges at a faster rate using my Choetech smart charger. I'm going to have to drain the battery and see how long it takes to fully charge with the stock charger

When I checked mine it was charging at something like 2600-2800 but i only watched it for a few minutes, might have gone higher

Yeah but they will most likely put a $769 hold on my card... :S

Some phones ie lg v10 do not "fast charge" while screen is on (while youre looking at it) to avoid overheating. Ampere cant show max charging rate. I use a usb sleeve (usb doctor) that displays that info or turn on notification display
EDIT: Supposedly Pixel do not fast charge while in use either.

I think I can confirm this. Last night mine showed 27 minutes to charge from about 50% but after keeping the screen awake for about 30 seconds, it went up to 51 minutes.

I also find my Pixel charges very slow as well even though it says Charging Rapidly (OEM charger, cable). The GSM Arena review said they went from 0% to 46% in 30 minutes, I get more like half of that at most. I used Ampere and it said i was only charging at 710 mA.....

If you charge it from almost empty it charges very quick, but slows down once it gets nearer to full

Yes i started charging my phone when it was 4%, and when i looked at it about 20 minutes later it was only at 16%. I think it took about 3 hours to fully charge. The only modification I've made to the phone is unlock the Verizon bootloader and flash the P software (which was subsequently updated to V). I'm seriously wondering if the charger or cable is defective.

Potentially, mine was and I had to get the whole thing replaced

Rapidly charging?

Is there any indication which I can see on the phone when it does rapid / fast charging?
What to check if my 2 XL doesn't fast charging? I am using included charger and cable, but I found it is terrible slow to charge. When I check the battery setting, it said "3 hours ... until fully charged" something like that

Completely normal
Google has done it intentionally to increase the longevity of the battery

Pixel will initially display "Charging Rapidly" on the lockscreen when you connect the cable. Disappears after a bit, only to return if you disconnect/reconnect.
I find rapid charging to be a bit slower than with the OG Pixel XL. I should let them both discharge and compare.

Slow wireless charge problem maybe?

So, I've got a question and a problem, maybe.
To wireless charge my 20ultra, I use my old anker circular 10w wireless charger. It works great on my s10+, but I noticed today that to charge from 4% to 54% it took 2 hours and half, which means it would take about 6 hours to charge from 0 to 100% (with fast charge enabled).
Now my question is, is this normal or should be much faster? And if should be faster, is it possible that the problem is that my s20u cant fully charge with my actual anker charger? Ive noticed that the camera module keeps the phone with little space over the charger (not much, but it's not totally touching it, lets put it that way), and with ampere app i noticed that when it charges it says 200-250mA (i think my s10+ had much bigger charge rate).
Do you guys think its definately the charger the problem? And can you suggest a good one working with s20u? I dont like having the phone standing when i charge it, which is why i always used the circular ones from anker, but it seems to have problems with the camera module... anyone else has it and can confirm me that?
Thanks!
