I have LG G4. I turn off my phone then plug in the wall charger. After a couple seconds i get the battery icon with moving dots indicating charging. Then a few seconds more the phone turns on.

Can I charge with phone off?

Please Help!

I've only turned on "USB debugging" to allow some programs to be installed and that's all.

There is no "keep screen on while charging" option.

Do you mean "Stay awake" option? (Screen will never timeout while charging)

Just plug the phone in first, THEN power it off. It should just come back on in a few moments to show the battery, but not actually be on all the way.

I know this, but the thing is not to put the charger while it's on... I had a few smartphones before this one, and they all charged while phone was off without turning the phone on.... is this the same with all LG mobile phones?

I'm not sure. All my previous devices acted this way. So if I, for faster charging or whatever reason, wanted to have the phone off but still charging, I would simply plug it in first, and then turn it off.

So when the phone is powered down and your charging it, after a while it powers itself back on? I've noticed this too actually. The first time the battery died on me and I went to charge it. When I went to pick the phone off of it's charger the phone was on again.

This is just the way it is. It's this way for most phones I've owned and I've owned quite a few.

The way to keep it off has been mentioned but plug in then turn off your phone. Otherwise plugging in starts a power up.

Guys, many thanks for clearing that up!

I was very worried about my LG G4, i thought that was defective. Strange thing is that I also have LG L70 and does not have this kind of issue....

So my final question is for the LG G4 owners:

WHEN YOU SWITCH OFF THE PHONE, DOES YOUR G4 TURN ON AFTER ITS CONNECTED WITH WALL CHARGER?

If you connect it to a wall charger, then power off the phone, no it should not turn on.

If you power off the phone, then connect it to a wall charger, yes it should turn on.

Hi I recently purchased the LG G4 and noticed the same thing. I do find it strange prefer to charge with phone switched off sometimes for quickness. I have owned many phone S3, S5 and couple of HTC none have done this! I think just one of those things nothing wrong with handset.

So on my first G4, I tried charging once with the LG charger, with the phone powered down, and that worked. The phone stayed off.

I just tried it again with my second G4, and the phone kept turning on again, even if I had the charger plugged in already, and then powered it down. I tried it a few times, with the same result. It then hit me that I'm currently using my Aukey QC 2.0 charger. I tried a generic, non-QC charger, and the phone stayed off when I powered it down with the charger plugged in.

My guess would be that Quick Charge requires the phone to be awake. If for no other reason than QC chargers need to do some data communication with the phone to find out what voltage the phone can handle, before QC is enabled. So maybe that communication requirement wakes the phone up.

Too bad, I was hoping QC + powering the phone down might give extra-quick charging.

Yes, mine does the same thing:

1) I enabled developer options to make sure the "stay awake" feature was not enabled and it was not.
2) I have already plugged in while off. Turned itself on while plugged I turned it off, it still turns itself back on.
3) Nothing in developer options was been messed with or turned on.
4) No other phone I've ever had has insisted on being on while being wall charged.
5) The phone will charge while off only while connected to the computer's usb.
6) I have the international version of the LG G4 bought on Amazon.com.
7) It is a bit of a pain in the a**

On the subject of charging, Im led to believe that this phone is supposed to be fast charging. My phone has been on charge now for an hour and is only up to 40%. Doesn't seem particularly fast. Ive read claims of 80% charge in 30 mins.

Does anyone have an answer for this yet? My phone turns on while charging regardless of cmination of plugging in / turn off or turn off plug in. I either have to turn all my notifications off, and my voicemail and my voicemail alert, or charge the phone at the other end of the house. Either way it's flipping inconvenient. No other phone I've ever owned has done this, just the LG. Which is going back to the shop if I can't find a resolution for it.
