When the battery charge drops below 6% for the 7000 mAh PowerPrecision+ standard battery, the device

NOTE: If you place a device with a deeply discharged battery on a device charger, the battery has to pre-charge to an op-
erational voltage level before the device can resume operation. This is indicated via the blinking amber LED. You must avoid
deeply discharging the battery as it can reduce the overall battery health.

Observe the following battery saving tips:
• Set the screen to turn off after a short period of non-use.
• Reduce screen brightness.
• Turn off all wireless radios when not in use.
• Turn off automatic syncing for Email, Calendar, Contacts, and other apps.
• Minimize use of apps that keep the device from suspending, for example, music and video apps.
