A good battery case should fit comfortably in your pocket or bag, adding protection without excessive weight or bulk.
High-capacity cases often sacrifice features like quick charging and Qi charging. These features are crucial if you plan to keep the case on your phone continuously. Wireless charging capabilities are particularly useful for simultaneous charging of both your phone and the battery case.
Battery Case FAQ
Are battery cases safe for your phone?
Yes, battery cases are safe for your phone when used correctly. They provide power directly to your phone, and once depleted, your phone's battery takes over. Smartphones are designed to monitor battery health and prevent overcharging. The only potential issue is overheating if the case lacks 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 damage them and reduce their capacity over time.
