What’s the best iPhone 6s battery case for you? Find out in our roundup of cases with built-in batteries.
Low on battery? Here we review the best iPhone 6s battery cases and iPhone 6s Plus battery cases, which also work with the older iPhone 6 and iPhone 6 Plus.
The Apple iPhone 6s has a battery life shorter than most owners would like it. Who hasn’t cursed as the “Low Battery” warning pops up? For all its fancy apps and super camera the more important feature of any smartphone is its battery, for when this expires so does everything else.
Apple went for super-thinness rather than significantly better battery life when it designed the iPhone 6 and 6s. So those of us who want our phone to last all day, and then some, have to lug round a battery power bank or forgo Apple’s slimness for a bulkier battery case that will recharge a fading iPhone battery back to full life without having to stop to find a power socket.
The iPhone 6 and 6s battery cases aren’t fully compatible with cases for the iPhone 7, iPhone 7 Plus, iPhone 8 and 8 Plus. Instead you can find out round-ups for those battery cases here: iPhone 7 battery cases, iPhone 8 battery cases.
If you fancy carrying a portable power pack (rather than a protective case) around with you, read our round up of the Best Portable Battery Power Banks .
Many of the iPhone 6 and 6s battery cases reviewed here are very similar me-too products, but each has its own pros and cons. What has excited us are the cases tested here that show some real innovation – such as the Tylt Energi Sliding Case and Esorun iStand, that offer something more. There are also cases reviewed here that are slimmer than most, or offer massive battery capacities. And sun hats off to Mophie for offering a battery case that’s also waterproof, the H2PRO.
Battery capacity can be measured in Milliamp Hours (mAh) and Watt Hours (Wh). The higher, the more charge you should get from the extra battery enclosed within the case.
