If the battery on your ZTE Blade X Max is faulty—short battery life, failure to power on, powering off before reaching 0%—and you have already been through our troubleshooting guide, then you will have to replace the battery.
This guide requires removing the back of the phone. You will have to use heating products to complete this guide. If you are using the iFixit iOpener, or a heating pad, be sure to follow the instructions for that particular product.
To remove the battery, you will have to heat the phone. Be sure not to overheat the battery. If you do, the battery will swell and be rendered useless.
