PinePhone Not Charging.
#1
Ok, I didnt want to post "me too" for gab's post of pinePhone not charging, but: "me Too".

I have +3V , +5V on the pogo pins, so I can guess that the USB is making a power connection to the mainboard.
The 4 pin battery connector has 0Volts on all 4 pins. The PinePhone seems to recognize that the phone is, or isnt plugged in, but will not charge it.

I have tried turning off all the kill switches, resetting, removing the sd card, at no point will the battery charge. Can I get a schematic of that circuit?
I have some hacks on how to force this thing to work (like solder a wireless charger directly onto the battery), but I'd really rather get it working as its supposed to.
I dont expect much in terms of warranty service, but some schematics, or community support would be much appreciated.

Additionally, are there any requirements for the usb charging device?
What is the charging power?  Is the USB C cable  anything special?
Can I charge the PinePhone via a computers USB port?

Hi,

Not sure but, from what I've understood, the battery will not charge when there is no OS running and supporting charging.

For charging, a 15W capable charging unit is required for optimal conditions : https://store.pine64.org/?product=pineph...ly-adaptor
I once connected my Pinephone on a USB port (500mA ?) of my computer while using the phone (with Ubuntu Touch). The battery level hasn't gone up or down.  Using a 15W charging unit, the battery charges.

I noticed that while the phone is off with battery in place, the battery discharges pretty quickly.

I don't have a USB-PD charger yet, but my 5V/1.5A capable chargers were able to charge the battery (slowly) even when the phone was on. Didn't leave it alone w/ screen on, so that may still be a bit much to ask.

(I also used a USB volt/amp monitor to confirm that voltage stays at 5V and was indeed using full 1.5A)

except for testing several OSes from the SD card,  I have not made any changes to my Brave Heart edition phone.

I ran the battery down while "Testing"  turned it off, then removed the battery to make sure it was turned off,
  THEN, reinstalled the battery and connected the charger and it charged to 99%
 **( I also removed the SD card, because I noticed that some OSes seem to start on their own when you plug in the battery charger )  ?

I have been using a 28 watt Samsung phone charger.

NOTE :   Seems if you attempt to run only on the charger/adapter with the battery removed,  the wifi and the modem will not function...
