I never want my Android table to go to sleep, I can I prevent sleep mode?
How can wifi receive data when it is in sleep mode? Will it wake up regularly, or do something else? I tried to make a ping test to a full power management (sleep just after transmission) phone, and ...
So what exactly is sleep current? I need to measure the same when my android device is put to sleep and when it wakes up. How do I measure it? Is there any specific app / tool / device?
