Charging the Battery 
The phone battery should have enough power for the phone to 
turn on, find a signal, and make a few calls. Fully charge the 
battery as soon as possible. 
When the battery is low, the phone displays a message on the 
screen. As the phone charges, the screen displays status bar 
with the exact battery level. 
  WARNING! Use only ZTE-approved chargers and USB 
Type-C cables. Using unapproved accessories could 
damage the phone or cause the battery to explode. 
  CAUTION: Do not change the built-in rechargeable battery in 
the phone. Only ZTE or a ZTE authorized service 
provider can change the battery. 
  NOTE: Use the charger included with your phone to charge 
the battery. It is specially built to support QuickCharge 
3.0.
