Cant remove the battery
Will removing the battery delete everything on the phone?
You will have to take the phone apart to remove the battery. There is a video on how to do it. https://www.youtube.com/watch?v=MgDqYBUxGUE&edit=vd
You can't. not unless you disassemble the phone
Simply open the back cover and pull the battery up. You can find this on the user guide you can download on ZTE Quartz page here in The Informr.
