How We Decided

In determining the best iPhone battery case to buy, we explored construction, wireless charging ability, battery life, simultaneous battery/case charging, and LED battery life indicators.

Construction should be rock solid, with raised bezels and hard backshells for impact protection.

Battery life should be good enough for a minimum 15 hours of talk time and both the phone and case should be able to charge at the same time to get you powered quickly.

LED battery life indicators are a very clever addition. Some picks, like the Apple Smart iPhone Battery Case, have integrated lED battery indicator lights built-in to the back case to show you how much juice the case has left. It is a great alternative to checking your Home screen or an app.

Best iPhone Battery Cases Buyer’s Guide

The Most Important Features to Consider

  1. Construction
    We recommend iPhone battery cases with rugged construction. Preferably, they have raised bezels and hard backshells to provide enough cushioning if dropped. It also prevents the screen from making direct contact with the ground.
  2. Wireless Charging
    Some picks, like the Apple Smart and the Alphatronix iPhone Battery Case, enable Qi wireless charging. A third brand, Mophie, uses Charge Force technology, which adapts its battery cases with wireless charging accessories such as car vents and desk mounts. This is a welcome relief over using flat surface wireless charging pads.
  3. Battery Life and mAh
    We aimed for batteries with a minimum 2000 mAhto power phones with an additional 24 hours of talk time.This should comfortably fit within most people’s tolerance levels for recharging frequency. Keep in mind, iPhone battery cases that charge the phone and case at the same time should be able to power your phone with no down time if you stay on top of manual charging.
  4. Simultaneous Phone and Battery Case Charging
    Look for iPhone battery cases that charge with your phone at the same time. This increases productivity by reducing the time it takes to power both devices.
  5. LED Battery Life Indicator
    Bonus points for iPhone battery cases that have LED indicator lights integrated into the actual case. Two of our picks show battery life in 25 increments. This prevents folks from checking their Home screens or Today View to find out.

When shopping for the best smartphone, like the best iPhone, make sure that you get the best iPhone cases to protect your phone, just as you would when buying the best iPads.
