Selecting the ideal battery case isn't just about finding the one with the largest capacity; it's about balancing battery size, overall dimensions, and cost. If you're only occasionally using a case, a portable charger might be more practical. However, if you need constant power and protection, finding a case that fits comfortably in your pocket or bag without adding too much weight is crucial.
High-capacity cases often sacrifice features like quick charging or wireless charging for more energy storage. If you plan to keep the case on your phone continuously, these features become essential, especially for simultaneous charging of your phone and the case.
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 are equipped with monitoring systems to prevent overcharging. The only potential issue is overheating if the case lacks proper ventilation.
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.
