Which iPhone has the best battery life?

Posted by Lian Nguyen

You’re interested in a getting a new iPhone, and you want to know which phone has the longest battery life. Finding a phone that has a long battery life is a huge factor, due to the fact that the longer the battery lasts, the longer you can use your iPhone, it would be beneficial for when you are on holiday or spending a whole day out.

Apple claims the iPhones with the best battery life are the iPhone 11 Pro Max and iPhone 12 Pro Max. Both are designed to last for 12 hours of video streaming, 20 hours of video playback, and 80 hours of audio playback.


Apple has changed the way they advertise battery life since last year. They now share video playback as streamed, instead of wireless.

iPhone 12 Pro Max has the largest battery, by far. The iPhone 11 has better battery life than the iPhone 12 Mini since it’s a larger phone.


Major factors that can affect your battery life

There are plenty of different factors that will determine exactly how long your smartphone battery will last. Some of these are obvious, some aren't. Here's a quick look at a few of the important ones.

Screen time:

Funnily enough, your phone uses a lot more battery when the display is on (as opposed to sleeping). As such, listening to music or a podcast (with your screen off) won't use anywhere near as much battery as watching a video.


Which apps you use:

Not all apps put the same kind of strain on your smartphone. For example, watching a video on your phone will use less battery than playing a game. For a phone, playing a video is a simple task. To run a game, on the other hand, the processor has to work much harder.


Network coverage:

Patchy network coverage can negatively impact your phone's battery life. Constantly searching for signal and trying to reconnect to a network can be quite a demanding task.



The iPhone 12’s has access to 5G which is good for speed, but this can come to a disadvantage as it tends to drain your battery faster in comparison if you were on 4G.



GPS - and mapping apps - can be surprisingly battery intensive. When using GPS, your device needs to communicate with three or four satellites for an extended duration of time. It doesn't help that your phone is typically running multiple tasks when using an app like Google Maps or Apple Maps. You've got your GPS connection, your phone display is on, and you're using mobile data for the maps and traffic information. There's a good chance you're also moving at the same time, so your device will need to work harder to maintain its GPS connection. Battery life isn't easy to measure. A number of factors will affect exactly how long an iPhone will last. If you don't use your phone much, you'll have a very different experience to someone who doesn't put it down all day.
