Possible S9+ Charging Issue??

[tmozer]

Brought my unlocked S9+ home from BestBuy Friday (the first day they became available in the US). I successfully charged it up a couple times with the provided Samsung quick charger (wired) and a cheap wireless charger I grabbed at Walmart. However last night, having the phone on the charging stand I noticed the phone's red LED remained on too long even though the charging stand light indicated it was charging the phone. Finally early this morning I checked the battery level and it had gone down. The phone was not charging. I plugged the phone into the Samsung charger for the rest of the morning. After an hour or so I checked again and the level had drop a few more percentage points! WTF?? Anyway I shut down the phone and then tried again with the wired quick charger. This time it charged fine.

I wonder if this is a pending future problem. To be honest I was watching a YouTube tutorial last night on how to bring up the diagnostic screen (using a series of phone pad key presses). I wonder if that messed with the phone somehow (I did not knowingly make any changes. Just tried some of the "tests").

Anyway, hopefully this was just a one time issue...... If not, I'll report back.

Aftermarket fast wireless chargers can be finicky. I highly recommend one of the Samsung fast wireless chargers as it had a fan built in to keep the temperature in control. I've never had a problem with any of Samsung's fast wireless chargers (fixed and convertible). I have had some issues with aftermarket fast wireless chargers in my car where they put in protection circuits for high temperatures where it starts to interrupt the charging while it cools down. when this happens, I usually have to aim my AC vent at the phone for it to work properly.
