When deciding what iPhone to buy next, battery life is most likely a deciding factor. No matter if you’re someone who is going to be camping and want other things to think about or someone who uses the phone a lot but don’t always have access to a charger. In the past years, smartphone companies have started making bigger and bigger phones which means more space for a battery but that doesn’t automatically mean more battery life. Bigger screens with higher resolution consume more energy and phones have actually gotten a tiny bit thicker which could be to keep up with the battery life in older models.
As you’ll see in the table below, the battery life has increased in some models but when you compare them to how much the battery capacity has increased it proves that the phones are using more energy to do the same thing they used to do on a smaller screen.
I would like to focus on Apple’s iPhones today. With the new releases of iPhone Xs, Xs Max, and iPhone Xr, Apple has a lineup of seven different phones with different battery sizes. Let’s take a look at how they compare. I have also added iPhone X even though it’s not for sale by Apple anymore.

Some interesting takeaways about the latest iPhone-models
- Although the iPhone Xr has a smaller battery when compared to the Xs Max, Apple advertises two hours better battery life when surfing the web. This is due to the Xr’s LCD screen. Xs Max is running a higher resolution OLED panel which consumes more power.
- The almost 20% bigger battery in Xs Max vs Xs only adds one hour of internet use, but five hours of wireless talk time and audio playback.
- The battery in the new Xs is 2.1% smaller than the last years X battery but only results in one hour less of wireless talk time.
- Don’t miss that: The newest models have three different screen sizes. Xs has a 5.8″, Xr has a 6.1″ and Xs Max has a 6.5″ screen.
So which iPhone has the best battery life? The iPhone Xr.
If you are looking to buy the iPhone with the best battery life in 2018, the iPhone Xr should be your choice. Even though the battery is smaller (2942 vs 3174 mAh) when compared to the Xs Max, it will deliver two hours of additional internet use when the Xs Max has run out of battery. As written earlier this is partly due to the differences in screen resolution and technology.
That said, there is nothing wrong with the iPhone Xr screen. It has been criticized for not running a 1080p screen in 2018 and while I understand the critique, it could actually benefit people that go camping and don’t have unlimited data or good service everywhere. By having a screen with less resolution YouTube and other video services will not try to run a 1080p video because it doesn’t make sense to do on a non-1080p screen. This will help you save data and battery life.
Something else to take into account if you’re thinking about buying an older model like the iPhone 7 or 7 Plus is that since iPhone 8, all iPhones released support something called fast charge. This makes it possible to charge your phone from 0 to 50% battery in 30 minutes when using the right power adapter. You can read more about that here on Apple’s website.

Take into account that most companies advertise a slightly higher battery life than what users usually see in the real world. I wrote this article to give you a broad overview of what Apple has to offer in terms of battery life.
