How to Choose the Best Battery Case
Choosing the right battery case isn't just about finding the one with the largest capacity; that could result in a bulky case that's hard to carry. The ideal case balances battery capacity, size, and price.
If you're looking for something to throw in your bag occasionally, a portable charger might be more suitable. A battery case molded to fit your phone is only beneficial if you plan to use it regularly. You need a case that fits comfortably in your pocket or bag without adding too much weight or bulk, while also providing protection.
High-capacity battery cases often sacrifice features like quick charging and Qi charging for more energy storage. These features are crucial if you keep the case on your phone constantly, especially for simultaneous wireless charging of your 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 is depleted, it switches to the phone's battery. Smartphones have built-in monitoring to prevent overcharging. The main concern 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 the battery and reduce its capacity over time.
