  • Normally people will be using this case when your iphone is at 100% and this case is at 100%. From there you will see an extended battery life for your iphone without the need to charge it.

  • That's going to depend on multiple factors, like internal battery health and usage. Using Apple's guide, with a BRAND NEW iPhone 11 Pro Max streaming video, you'd normally get up to 12 hours average, so you'd get up to 18 hours with this case. Up to 80 hours of audio playback normally, so you'd get up to 120 hours and so on.
