Extra battery power on the go

While the larger handsets like the iPhone 13 Pro Max have bigger and better batteries than their smaller counterparts, this model is getting older and your battery health may have declined a bit. It's worthwhile to invest in a portable battery case if you find yourself away from your charger for hours or even days at a time. The AFTRYOUGO Battery Case for iPhone 13 Pro Max comes highly recommended for its reliability and powerful 7000mAh battery.

However, I'm personally not into battery cases. I find them a bit unwieldy, making the iPhone heavier and more awkward to hold. Since you really only need them when your phone's battery is getting low, they may not be ideal to use all of the time. In my own personal life, I use a regular MagSafe case and pop on a MagSafe battery pack when I need some extra juice. I've tested out a number of them, and the U by UAG Power Battery is the one I'm most likely to grab on my way out the door for a long day of exploring. It comes in several colors and has a handy kickstand/phone grip on the back for video viewing, FaceTime, and selfies.
