Should I turn my phone off at night or just lock it, to minimize battery usage and battery wear, and also wear to the flash memory? This question is similar to Should I keep my Android tablets' power off or leave them on standby mode?, but my phone's encrypted, so everytime it boots up it has to decrypt, which I'm guessing uses up quite a bit of battery to do and IO operations to the device storage.

Personally I enable airplane mode at night to minimize battery usage. So the device doesn't require a boot when I'm ready to start the day. Just disable the airplane mode.

Airplane mode just disables radio signal (cellular services, bluetooth, etc), since it draws most battery juices.
