Your Pocket keyboard will keep you typing for up to three months of regular use.
You can check its remaining battery power any time you like. To check the battery
life press fn + the battery key (ctrl). The LED will flash one of three ways.
1. Three green flashes indicate a full battery.
2. Three yellow flashes indicate low battery power.
3. Three red flashes indicate critical battery power. When your Pocket reaches a
critical level, the red light will flash once every two minutes.
To help preserve battery life, your Pocket will enter sleep mode if left on and
not used for several minutes. To awaken your Pocket, press any key. The Pocket’s
battery has no memory and may be charged whenever you wish.
