How to Choose the Best Battery Case
Choosing the right battery case isn't just about the largest capacity; it's about finding the perfect balance between battery life, size, and cost. If you're looking for something to carry in your bag, consider a portable charger instead. A battery case should fit comfortably in your pocket or bag without adding too much weight or bulk while offering protection.
High-capacity battery cases often sacrifice features like quick and wireless charging. If you plan to keep the case on your phone constantly, these features can be crucial, especially for 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 as long as they are used correctly. Your phone draws power directly from the case, and once the case is depleted, it switches to your phone's battery. Smartphones have built-in safeguards to prevent overcharging. The main concern is overheating, which can be mitigated by choosing a case 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. Completely draining the battery can damage it and reduce its capacity over time.
