Changing the power management plan
Your tablet has three different power options: High performance, Balanced

use more energy. Balanced (recommended) automatically balances performance
with energy consumption. Power saver favors saving energy to extend battery life.
To change the power management settings, tap the APPS icon in the top-right
corner of the Home screen. Tap Settings and under Device, tap Power options.
Tap Power Plan and tap the power management plan you want.
