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 size, overall dimensions, and cost. If you only need the case occasionally, a portable charger might be more practical. However, if you're looking for a case that stays on your phone, consider one that fits comfortably in your pocket or bag while offering adequate protection.
High-capacity battery cases often lack features like quick or wireless charging. If you prefer to keep your case on your phone at all times, these features can be crucial, especially for simultaneous 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. The phone draws power directly from the case, and once the case is depleted, it switches to the phone's battery. Modern smartphones are equipped with safeguards to prevent overcharging. The primary 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. In fact, doing so can damage the battery over time, reducing its capacity. It's best to charge these batteries whenever convenient.
