Swearing is brilliant if you smash your thumb with a hammer, or break something expensive. If you swear all the time in normal conversation you don’t have any special words left to use when those things I mentioned happen.

if the device switches off while in use on charge, that’s too slow. if the device switches off whilst charging because it overheats, that’s too fast. in between, forget it, the electronics will handle everything, and yes slower charging is better for battery life but you needn’t obsess over the difference, it’s there but unquantifi able. if you’ve heard anything other than this advice and you believe what you’ve heard, there’s not much point in people here trying to guide you.

Ah, but which brand of washing machine, that’s what we’re all about here in this thread!
