The iPhone XS is one of the best smartphones on the market with plenty of powerful features. It won’t run forever on battery though. The good news is you can always use a battery case to use your phone on-the-go longer. Take the JX iPhone XS battery case for instance: it has a 5000mAh battery and a LED display to conveniently show remaining battery juice.
This battery case has an intelligent chip for short circuit prevention. It is available in blue and black version. A larger version is available for iPhone XS Max users.[where to get it]
