How to Choose the Best Battery Case
Choosing the right battery case isn't just about finding the one with the largest capacity; it's about balancing capacity, size, and price. If you only need a charger for occasional use, a portable charger might be more practical. A battery case should fit comfortably in your pocket or bag, add minimal weight and bulk, and provide protection for your phone.
High-capacity battery cases often sacrifice features like quick charging and Qi wireless charging. These features are crucial if you plan to keep the case on your phone at all times, as they allow for convenient simultaneous charging of your phone and the case.
Battery Case FAQ
Are battery cases safe for your phone?
Yes, battery cases are safe for your phone if used correctly. They provide power directly to your phone, and once the case's battery is depleted, the phone's battery takes over. Modern smartphones also monitor battery health to prevent overcharging. The main risk is overheating if the case lacks proper ventilation.
Should you drain your battery case before charging?
No, there's no need to fully drain the lithium-based batteries in battery cases. Doing so can damage the battery and reduce its capacity over time.
