OnePlus Nord, purchased new from Murena ~3 yrs ago. I started seeing this issue several months ago, and I should have posted about it long before now.
3 or 4 e/OS versions ago, immediately after an OS upgrade, recharging became extremely slow (30-90 minutes for each 1% of charge – recharge 3-15% overnight).
The first time this happened, I didn’t even connect the issue with the OS upgrade … for a couple of nights in a row, I just thought I hadn’t plugged it in properly, and it quit charging sometime in the night. Eventually, I realized it was just recharging very slowly … but by then, it was down to 15-20% and it took 4+ days (24 hours a day) to fully recharge the phone.
However … after one full recharge and then power cycling the phone, the issue disappeared, and normal recharge speed returned.
The next OS upgrade, same thing happened – this time, I connected the dots. Same solution, too – fully recharging the phone (3+ days), then power cycling it solved the issue.
Last OS upgrade, however (to 3.0), the issue has not gone away. I am now stuck with a phone that I can only recharge, at best, 20% overnight (if I shut off every non-essential app in the phone and turn off the display).
Oh yeah … trying to charge the phone while it is turned off does not work, at all.
I just now upgraded to the latest 3.1.1 version of e/OS, and the issue remains. I even tried the “slow-charge back to full, then reboot” trick, and that has not resolved it, either.
Any suggestions? As usual, thanks in advance.
