send out signals to locate a base station and drains the battery. So, just temporarily turn
off the tablet, or move the tablet in range of a network it can connect to, or temporarily turn
off the wireless connection on your tablet.

battery will drain quickly too. It is normal in this case. User can disable it by selecting
“Never check for update”. However, it is not recommended. User should be cautious
before doing this.
