Part of the reason mine is on vibrate except when on the charger.
No more getting woken up in the UK at 3 AM by a stateside colleague wanting to talk.
I forgot to charge it....
The problem is my new phone is only supposed to be charged when it’s off, and I don’t like to have my phone off when I’m away from the shop, as that’s the first number the security company will call if the shop alarm goes off.
So I have to remember to turn it off and charge it, for short periods when I’m home. The good thing is that it charges quickly.
I don’t know if the low battery alarm will sound if the phone’s on vibrate...
