What matters most
What to consider
When selecting a battery case for your iPhone 6 Plus, consider your primary needs. If you're a power user who needs to last multiple days without a wall charger, prioritize cases with the highest mAh capacity, like the Alpatronix BXX or ZeroLemon. For everyday use, a case offering an additional 50-70% charge, such as the Mophie Juice Pack Plus, might be sufficient and offer a more balanced form factor.
What to consider
Think about the level of protection you require. If you're prone to dropping your phone, a rugged case like the ZeroLemon will be more suitable. If you prefer a slimmer profile, look for "ultra-slim" designs from brands like Anker. Finally, consider your budget. While premium cases offer more features, there are excellent value options like the JCE battery case that provide essential power extension at a lower cost. Always check recent reviews for the most up-to-date user experiences.
