- Start with a fully charged battery. (Duh!)
- Dim the backlighting on the keyboard to off. (Not really necessary. Nice feature though.)
- Turn the contrast down on the screen to about 30 percent. (This is still plenty bright enough to read the screen clearly.)
- Disable LTE receiver and only connect to Wifi.
Note: I expect the battery life to change when I use LTE which I do when I am not in my office, but I haven't tested that yet.
