Phone loses battery when connected to computer

[Zolotoy]

Just upgraded to 383. Currently the phone is connected to computer. It shows charging. But battery charge is actually going down. It was 22, not it's 20. The phone is a bit warmer than usual. So, what is charging what?

Thanks

I upgraded to the latest insider build yesterday evening. My battery drained down to zero within about 3 hours and was also quite warm. That was last night. This morning I recharged the phone and it's working like a champ. Maybe it needed to sort things out a bit. It's unnerving though isn't it 😨

Guess you are using a 2.0 USB port and your pc detected it as a low cahrging device. try rebooting your pc. USB 2.0 standard is 0.5 Amperes. Not much but enough for stabilize charging during use. USB 3.0 go from 0.9 to 2.0 Amperes according to port techs (Fast Charge, etc)

Who/what needed to sort things out?

That is not a first time the phone is connected to the computer.

I imagine that, that's a random thing

Same after restarting. Does that mean the phone cannot be charged from PC anymore?

No, it means phone is still doing something drainign its battery. Go to Settings -> Battery -> Show use per apps

I see. I checked the apps and I have WatchESPN showing 45%. The settings are: never allowed in background. Is this somehow wrong?

Or you are watching ESPN streaming all day long, or something in their app doesn't work. Ask their developers

After looking into apps the phone all of a sadden stopped draining battery and now it's charging. I guess we just found a 'proper' way of stopping battery drainage.

So I had the exact same problem last night. Something is syncing in the background after the update and it's just going crazy. The good news is it will sort itself out. Connect it to the fast charger (only way I could keep it from draining to 0) and leave it connected to WiFi for a good 8-10 hours. Don't do anything with it (not that you would really want to, swear I could have cooked eggs on it and it was painful to touch). Then it will be back to normal. Took it off my charger at 6am this morning with 100% and it's sitting at 85% now at almost 3pm.

I was concerned initially but decided to leave it alone, seems like it was a good choice.

Btw for me it was Microsoft Health showing almost 50% battery usage. It's dropped now.
