device is new. 
When i use wireless charger then speed charge. 
What is problem ?

Replace a data line to verify how long it takes to charge the wireless charger and how long to charge the line.

With wifi charger it is charge in 50-70 minute estimated. I dont know really because wifi charge has no problem. it is charge fast and quick. 
But with data cable  more than 1 day it is still charging and not full

FYI,
i have 3 BLACKVIEW BV9900 pro's,  and here is what i have found.

these devices CAN charge at up to 9 VOLTS,  but the software is incorrect and the device only uses 5 volts @ up to 2AMPS.

tested this with 100's of chargers and cables.   (yes i really do have too much stuff)
 BV9900 PRO  with android 10 will not do voltage boosted charging.   
-i need to downgrade one of these to the android 9 version, to see if the software lets MEDIATEK handle charging.  ( have NOT tried android 9 on this device yet )

Hey everyone I had the same charging issue , my phone suddenly started charging very slowly. I could only get a full charge after leaving it almost 24 hrs in original charger for almost 24 hrs. Went on Amazon ordered a new cable and I'm back to fast charging .

Thanks.

Or, which Pump Express charging version is installed on the phone?
