Installing or removing the battery

Your smartphone uses a replaceable battery to provide power. It is packed 
separately from your smartphone and needs to be inserted and charged before you 
can use the smartphone.

Installing the battery

Insert your fingernail into the micro USB port between the battery cover and the 
phone. Unclip the cover with your fingernail and lift it off the phone.
1. Align the gold-colored connectors on the battery with the connectors at the top of 

the battery compartment. Replace the battery.

2. Replace the cover and push down until it clicks in place.

Charging the battery

For initial use, you need to charge your smartphone for eight hours. After that, you 
can recharge the battery as needed. Connect the AC adapter cord to the micro USB 
connector on your smartphone.
