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 life, size, and cost. If you're only planning to use the case occasionally, a portable charger might be more suitable. A battery case should fit comfortably in your pocket or bag without adding excessive weight or bulk, while also providing protection for your phone.
High-capacity battery cases often sacrifice features like quick charging and wireless charging for larger energy storage. These features are crucial if you prefer keeping the case on your phone continuously, particularly for simultaneous wireless charging of both the phone and case.
Battery Case FAQ
Are battery cases safe for your phone?
Yes, battery cases are safe for your phone as long as they are used correctly. Your phone draws power directly from the case, and once the case's battery is depleted, it switches to the phone's battery. Smartphones have built-in monitoring to prevent overcharging. The main concern is overheating, which can be mitigated with proper case ventilation.
Should you drain your battery case before charging?
No, it's not necessary to fully drain lithium-based batteries in battery cases. In fact, allowing the battery to completely discharge can damage it and reduce its capacity over time.
