Best Battery Case for Apple iPhone 11, 11 Pro and 11 Pro Max
The iPhone 11 family has great battery life already, but you might require extra charge and you definitely need protection.

Apple is getting better at increasing battery life in its iPhones, with the iPhone 11 Pro’s battery lasting an amazing 4 hours longer than the old iPhone XS.
The iPhone 11 lasts an hour more than the iPhone XR, which previously held the iPhone battery-life record.
The iPhone 11 Pro can playback video for 18 hours or blast music out for up to 65 hours - if that’s all you do, of course; most of us use our phones for many tasks, and all eat up power.
But, at the same time, we dream up new ways of using up that battery life as quickly as we can – streaming movies and TV shows, playing games, taking ultra-wide photos, and so on.
And sometimes we all forget to charge our phones overnight, and wake up with the dread fear of a fading battery through the day.
So even if the new Apple iPhones should last longer, they won’t always get you through a busy day of phone use – and certainly not a long-haul flight where you watch your own entertainment channels.
You can carry a spare battery pack around with you (check out our recommended best power banks), but that can be cumbersome and entail loose cables, etc.
Or you can buy a battery case for your iPhone 11, 11 Pro or 11 Pro Max, which will give you up to another full charge of juice for when you really need it.
A battery case also offers you something else every iPhone needs: protection.
iPhone 11 models are all different sizes
Important! Always check you are buying the correct case for your model of phone. Each member of the iPhone 11 family is a different size, so you need to have the exact case for each phone.
The iPhone 11 has a 6.1in screen (measured diagonally), the iPhone 11 Pro is actually a little smaller with a 5.8in screen, and the biggest is the iPhone 11 Pro Max with a 6.5in screen.
What to look for in a battery case
Capacity: In our experience of phone battery cases, 4,800mAh should be fine. Many claim larger power capacities but rarely deliver more than a full recharge (100%) – and that’s all you really need, until you can plug the iPhone in again and power back up.
Protection: The other point of a battery case is to protect your precious iPhone, so look for a decent bumper around the case to save it from drops and a front bevelled edge that will protect the screen from scratches.
Size: There’s no getting away from it – including an extra battery in a case is going to make that skinny, lightweight iPhone into something a bit fatter and heavier. As the iPhone 11 has improved daily power, we think you can keep the battery case for those times when you will need it most: long-haul travel, time away from a power socket, or, most likely, those emergencies when you’ve forgotten to charge the night before. Or you might be something of a power user and drain that 11’s battery faster than most.
You’ll still need a case for protection, so take a look at what we think are the best cases for iPhone 11.
Fit: The case should also fit the phone snuggly, but not so inflexible that it’s a pain to put on or pull off. The best ones are a one-piece design where you pull back the soft top and slide the phone in, where it connects with the case’s Lightning connector.
Make sure you buy for the right model as the iPhone 11, 11 Pro and Pro Max are all different sizes. We have marked compatibility on the individual reviews below.
We have recommended plenty of our favourite iPhone 11 cases, but here is our list of tested battery cases for the iPhone 11 family.
Testing methodology
We test for real-world battery capacity. Simply, we wait till the iPhone is down to 20% charge, and then activate the battery case.
When the iPhone is up to 100%, we turn off the battery case, and leave some in there until you need to use it again. Then we add the two charge percentages together to see how much charge you’ll get from each case.
The Apple case works in a different way, so we just slipped a run-down iPhone into the case to see how much extra it was charged to afterwards.
It’s not super scientific but this is how you’ll use the case in real life.
What’s available now?
Aside from the expensive Apple Smart Battery Case, you can find an army of Chinese iPhone 11/Pro/Max battery cases online for a fraction of that cost, and we have been testing the best of them.
A lot of those with the best online reviews (which we then tested, below) are virtually identical (even the data printed there is the same), but one did stand out with a key extra function. And there are more coming through with some design options.
