And how would family contact you overnight, in case of emergency?Keeping the phone on 24/7 wears out the battery faster than if it is turned off every night, even if it's left in the charger - due to micro cycling of the battery. Unless you want to talk on the phone at 3am, I can't see any reason to keep the phone powered up overnight.
A fresh reboot every day (if you must keep the phone powered 24/7) accomplishes a lot of good things and only takes 30 seconds.
The battery wear just keeping the phone on 24 x 7 is negligible (in and of itself). I don't believe such wear justifies turning the phone off at night, especially when you can't receive emergency calls.
