Rather than announcing just one new iPhone this year with two different screen sizes, Apple shook things up by announcing an entirely new iPhone X with a 5.8-inch edge-to-edge OLED display alongside their typical 4.7-inch and 5.5-inch iPhone models.

There’s bound to be some confusion about some of the most important specs between the devices, so in this piece, we’ll talk about the differences in weight, dimensions, and battery life as we do every year.

Battery Life

Battery life is perhaps one of the biggest factors when it comes to choosing the right iPhone for you. Typically, the Plus-sized models get improved battery life because of the larger surface area that makes packing a bigger battery possible, but it’s still good to know the details.

First, we’ll compare the smaller handsets to the iPhone X:

From here, we can see that the iPhone 8 lasts about as long as an iPhone 7 would, but an iPhone X can last up to 2 hours longer on a single charge than an iPhone 7 or 8 would. There are differences across the board, from talk time, to internet use, to audio/video playback.

On the other hand, only the iPhone 8 and iPhone X support fast-charge, allowing your battery to charge up to 50% from dead within half an hour. These are also the only two handsets that support wireless charging with a Qi-compatible wireless cradle.

Next up, we’ll compare the Plus-sized devices to the iPhone X:

In this data, we can see that the iPhone 8 Plus lasts about the same as the predecessor, but this is where the iPhone X starts to lag behind a little bit. It’s on par with the Plus-sized handsets concerning talk time and audio playback, but the Plus-sized handsets marginally beat the iPhone X on battery life in both the internet usage and video playback sectors.

Just like with the smaller 4.7-inch handsets, the 5.5-inch handsets follow the same fast-charge rules. Only the 8 Plus and the X support fast-charging capabilities, allowing you to juice-up quickly from 0-50% in 30 minutes. Moreover, only the 8 Plus and the X support wireless charging with Qi-compatible cradles.

Size & Weight

One of the other most popular questions is how the device will feel in your hand on a daily basis, and for that reason, we’ve got a comprehensive comparison of size and weight between the three handsets to show you.

Once again, we’ll compare the smaller handsets to the iPhone X first:

What we see here is that there’s a marginal increase in depth, height, and width between the iPhone 8 and iPhone 7 that you probably won’t even notice on a day-to-day basis. In fact, you probably wouldn’t even see it if the devices were right beside one another. Regarding their weight, the iPhone 8 is about 7.2% heavier than the iPhone 7.

Most you are probably interested in the iPhone X, and it’s fairly larger than both the iPhone 7 and iPhone 8. In fact, it’s 3.9% taller, 5.7% wider, and 7.1% thicker than the iPhone 7. Regarding weight, iPhone X is 26.1% heavier than the iPhone 7 and 17.6% heavier than the iPhone 8.

In conclusion, iPhone X is beefier than either the iPhone 7 or iPhone 8, so that might take some getting used to if you’re making the switch.

Next up, we’ll compare the Plus-sized devices to the iPhone X:

In this case, the Plus-sized devices are still the king of the roost. The iPhone X is both smaller and lighter than both Plus-sized models. The dimensions are nearly the same between the iPhone 8 Plus and the iPhone 7 Plus, but the iPhone 8 Plus weighs about 7.5% more than the iPhone 7 Plus does.

Comparing the Plus-sized handsets to the iPhone X, this is where the numbers start to get interesting. The iPhone X is much smaller than both Plus-sized handsets; it’s 9.3% shorter and 9.1% narrower, than the iPhone 7 Plus, but 3.4% thicker. Regarding weight, the iPhone X is 7.4% lighter than the iPhone 7 Plus and 13.9% lighter than the iPhone 8 Plus.

That said if you’re using a Plus-sized device right now and you’re considering the iPhone X, it will feel a lot like you’ve just bought an iPhone 8 or iPhone 7 until you glance at the mesmerizingly-large display, which dwarfs even the Plus-sized handsets.

Conclusion

Keep in mind that the iPhone 7/7 Plus and iPhone 8/8 Plus are nearly the same size as one another, so cases for each handset should be backward-compatible. With that in mind, if you have an iPhone 7/7Plus and you’re upgrading to the iPhone 8/8 Plus, you shouldn’t really need to buy a new case.

If you’re getting the iPhone X, on the other hand, Apple has never made an iPhone quite like it before. You’ll almost certainly need to buy yourself a whole new case to fit the new handset, regardless of whether you owned a 4.7-inch or 5.5-inch handset previously.

In terms of battery life, the iPhone 8 Plus is probably the way to go, but most people will want the latest and greatest features of the iPhone X, so a slight trade-off in battery life probably won’t make or break the demand for it.

If you’re also considering an Apple Watch Series 3 to go along with your new handset this year, then you might want to read up on how the Series 3 compares to the previous-generation Series 2.
