One of the best things about the iPhone 11 Pro and iPhone 11 Pro Max this year are the incredible battery life improvements they bring. Sure the new camera is great, but the iPhone 11 Pro gives you an extra 4 hours of battery life compared to last year’s iPhone XS, and the iPhone 11 Pro Max gives you an additional 5 hours of battery life compared to its predecessor. Those numbers are incredible, but battery life isn’t really worth paying $1,000+ for. Instead, keep your current iPhone X/XS, iPhone XS Max, or iPhone XR and get a Szresm 3,200 mAh iPhone Battery Case on Amazon for only $20!
