Hey all, I've had an issue with my 820 lately in which it has been very finnicky about whether it wants to charge. Sometimes I plug it in and I get no charging indicator at all. Other times (like last night) I got the charging indicator, but the battery life kept going down anyways (it is currently on the last of its life). Sometimes it will charge, but it's unpredictable when that will be. I have tried multiple chargers and encountered the same issue. Has anyone else come across this / how was it resolved?
