I have an old samsung S21+ I don't use anymore and was thinking it'd be cool to turn it into a wireless charger via the wireless power share, but every time I take my Flip 5 off it, it turns of Power Share, and every time I leave it for a minute it turns off too.
Is there a way I can keep Powershare on indefinitely?
Indeed!
You can grab a fancy QI stand for like £16 not to mention OP is gonna fuck up their S21 battery using as such.
