5X only charges fast with screen off

[lordratner]

Is anyone else seeing this? My 5X is plugged into the included charger. If I am using the phone while it charges the battery stays at the same level. On the battery page it says 11 hours until full charge. If I leave the screen off it charges quickly, as advertised.

This happens whether I'm playing a game or just web browsing. On my old Nexus 5 I was able to charge the phone while using it easily. Obviously it went faster with the screen off, but it would still charge up while I used it.

With the 5X it seems like the charger can just barely keep up with normal use, which makes no sense to me, given how much power it provides.

Thanks,
Seth

When you plug your cable into your device, do you see the "charging rapidly" on the lockscreen?

 

[lordratner]

Yup. but if I'm using the device it'll say something like (11 hr until fully charged). If I leave the screen off for a while it'll say a normal charging time.

I'll have to pay closer attention. Have not noticed this happening to my 5X.

I have not that it had that experience. In fact I got a rapidly charging car charger that I can plug it in, at stop lights check things, do things here and there, and then whenever I get to my destination I've got hours of juice to use. At this point I don't even care that the battery life isn't up to par or going to last a full day for my normal use because of the chargers that I have stationed wherever I go. I only hope that they can create something for rapid charging so I can use my Mophie in case I am traveling during the day and need to charge.

Now sure I would love to have an all day battery like in the droid turbo, I don't know how they do it, and a Sony Xperia Z device, which I came from and was really spoiled with the excellent battery life. I'm hoping that the Nexus 2016 device will give us double the RAM, nothing over a 5.2 inch screen, and have a battery life that makes everyone happy. That is my dream!

Seems like a good feature. If you're using the phone while it's plugged in, it would probably overheat if it was also charging rapidly, so it makes sense to only charge rapidly when the screen is off.

Yes. I measured the charge current externally, watched debug messages and tried to get a clue from the source code where those messages come from, and come to the same conclusion.

The charge current seems to be limited if the screen is on (the temperature of some component seems to play a role here). In my case it typically drops to around 600mA. Reducing the current during screen on may be reasonable at some point, however those 600mA are just not enough to at least keep the phone at its current battery level.

Especially if using Google Maps etc., I'm wondering how this is supposed to work on longer trips.

After searching a bit on google, it appears as if the LG G4 has exactly the same issue, which is propbably no surprise.
Same manufacturer, same chipset.

I hope, LG will be adjusting this current limit to at least 1A or something more reasonable.

As a previous G4 owner, I was just about to mention I experienced something similar on my G4. It would still charge though. But...barely at all.
I have a habit of using my phone while it's charging...particularly in the car for music and GPS. This made it sometimes DEPLETE instead of even stay at its current percentage. I didn't like that.

I'm sad to hear the 5X does the same thing...I guess it makes sense, but it does make me give another slight point to Huawei's 6P as I try to decide which I want.
I just wish the screen size of the 6P were around 5.0-5.2.
