How to Choose the Best Battery Case
Selecting the right battery case isn't just about finding the one with the largest capacity; it's about balancing battery capacity, size, and price. If you only need a charger for occasional use, a portable charger might be more suitable. A battery case should fit comfortably in your pocket or bag, adding protection without excessive bulk.
High-capacity battery cases often sacrifice features like quick charging and Qi charging for more energy storage. These features are crucial if you plan to keep the case on your phone continuously, especially for simultaneous wireless charging of both the phone and the case.
Battery Case FAQ
Are battery cases safe for your phone?
Yes, battery cases are safe for your phone when used correctly. They supply power directly to your phone, and once the case's battery is depleted, your phone's battery takes over. Smartphones have built-in safeguards to prevent overcharging. The main concern is overheating, which can be mitigated with proper ventilation.
Should you drain your battery case before charging?
No, it's not necessary to fully drain lithium-based batteries in battery cases. Doing so can actually damage the battery and reduce its capacity over time.
