Android phones, apps and tablets

Depends what "off" you mean.

If you mean, screen off. Then it should wake for alarm.

If you mean, power off. Then it will not wake for alarm.

The Blackberry doesn't actually power off unless you remove the battery. It just goes into a low power standby. Which is why it can still wake for an alarm.

And the stock S2s do use battery like nothing... mostly due to the background Samsung apps. A good way of stretching battery life is to disable WiFi when not needed and to use 2g over 3g unless you need the fast data.

oh my.
thanks for the replies TS Dammit VB, its as bad as i feared.

what's so great about being tethered to needing a socket? how is this an advance... clearly I don't get it.

i want my blackberry back.

I have a new project for mircrosoft / intel / whoever makes these things..and their batteries.
