If your iPhone battery tends to run out before the end of the day, or you spend a lot of time traveling without easy access to a charger, a battery case could be the solution. But with so many out there, how do you know which are the best models?
These iPhone cases all provide some extra juice when you need it most, but beyond that we’ve carefully selected our top picks across a range of criteria – whatever your needs, we’ve got you covered!
Best on a small budget
Anker Premium Extended Battery Case (£30)
Going cheap doesn’t necessarily mean you miss out on quality: this Anker case is thin, light, and will more than double the battery life of your iPhone (with an impressive 3,100mAh capacity) without breaking the bank. What you lose at this price point is durability and looks. It’s a fairly plain-looking design and the plastic isn’t especially resilient to knocks and scrapes. For the money, though, this is an exceptional battery case and easily holds its own against more expensive models.
Best for a slim profile
Spigen External Portable Charger Case (£40)
This Spigen case has the exact same capacity – 3,100mAh – as the Anker model, offering a decent extra charge as well as protection for your iPhone. The main difference between these cheaper models is aesthetic, and down to your tastes. This one’s pretty slimline for a battery case, roughly doubling the thickness of an iPhone. An LED bar on the back shows how charged the case is, and it includes an auxiliary adapter to ensure compatibility with even the chunkiest of headphone jacks.

Best for long battery life
Mophie Juice Pack Ultra Case (£130)
If you want the juiciest battery money can buy, this Mophie case has you covered with it’s huge 3,950mAh capacity, which equates to around 150% of additional battery life. In other words, if you normally get 10 hours usage, you’ll now get 25 on a single charge. It’s not cheap, but it’s pretty slim for the size of the battery and also provides decent drop protection for your iPhone thanks to a clever internal bumper system.
