Oops... There has been a bit of a cock-up on the wireless charging front!
I bought a cheap wireless charger a few months back and have been very happy with it. It recharges my phone at about 1%/minute which typically amounts to only 30-45 minutes for a top-up**. It can also simultaneously (or independently) charge wireless earbuds and/or a smartwatch.
I put my earbuds on charge while I watched a TV show last night before turning in. The phone charger turns off when the phone is fully charged. I just discovered that the earbud charger does NOT! I forgot to check the earbuds before I went to bed so they have been left charging overnight. They got around 8 hours instead of the 2 hours that they needed. The earbud storage case/battery was warm when I switched the charger off just now so it was definitely putting unnecessary power in. Apart from stressing the battery and shortening its life, I think there must be an increased risk of causing a fault which would be a fire risk!
In future I will set an alarm on my phone to remind me to take the earbuds off the charge when it is finished.
** For those of you who can't be bothered with wireless charging... The reason that I have bought a wireless charger is that I have had phones develop faults at the USB socket and sometimes had problems with charging leads too. By going wireless, the only times I have to plug a USB cable in are when travelling without the chunky wireless charger, or to upload the latest version of the game that I am working on (and when I get a Google developer account I will be able to do
that wirelessly via the Play Store). I sync any photos I take to Google Photos so I don't need a cable for that. The phone should be a lot more reliable without me constantly connecting cables to it.
