iPhone X, iPhone 8 and iPhone 8 Plus Review - Battery Life and Call Quality

Which device is better in terms of battery life and call quality?

We take a closer look at the battery life and call quality of the iPhone 8, 8 Plus and X.

Battery Life

iPhone 8 Plus has the best battery life of all three new models, which can last for over 32 hours between charges on average. Battery life on the iPhone X is decent, in reality use, the iPhone X lasts a day with some juice left over - but not enough to go for two days, just slightly better than the iPhone 8.

More interesting is the 2,716mAh battery on iPhone X, which is actually bigger than the battery on the iPhone 8 Plus, which has a 2,691mAh battery. But iPhone X still doesn’t last any longer than iPhone 8 Plus. We do not know whether this is due to its new OLED display or something else.

Battery life is obviously one of the most important aspects of smartphones. There is another important aspect of battery life - Charge time. All three models offer wireless charging capability with Qi chargers and all three also support fast charging to the level of restoring up to 50 percent charge in 30 minutes.

Unfortunately, it’ll be a bit pricey if you want to get those speeds. Fast charging requires an Apple USB-C power adapter and Lightning cable. Apple doesn’t include any of these things in the box, they are sold separately. That means not only will you have to pony up for either a 1-meter or 2-meter cable at $25.00 and $35.00 respectively, you’ll also need to buy Apple’s $49.00 USB-C Power Adapter. A pricey investment… yeah, I know.

These three models also support wireless charging. Unlike conventional charging, where you plug a wire into a port, wireless charging happens via an electromagnetic field created by a charging pad. Apple is using a wireless charging standard, called Qi, that nearly every other company in the industry has adopted. Just like the fast charging, if you plan to use wireless charging, you need to buy a wireless charger. Apple sells a couple of Qi chargers in its store, and there are several cheaper wireless chargers on Amazon.

Call Quality

Some earliest iPhone 8 buyers reported a “static” and “crackling sound” when they made a call, but Apple has solved this issue. Now, all three models have the same call quality: They are loud and clear to hear callers from different environments, and the call quality is excellent, especially for those who can use applications like VoLTE and HD voice.


So which one should you choose?

Firstly let's take a look at the price:

  • iPhone 8: 64GB - $699, 256GB - $849;
  • iPhone 8 Plus: 64GB - $799, 256GB - $949
  • iPhone X: 64GB - $999, 256GB - $1149

These are Apple's most expensive smartphones, and iPhone X is the most expensive mainstream smartphone in the world.

We think the iPhone 8 is the best one for most people. The iPhone 8 is lightweight, you can actually hold an iPhone 8 with one hand, even for smaller hands, and it fits nicely in pants pockets. This is a big advantage over iPhone 8 Plus.

Compared with earlier models, iPhone 8 with the six-core A11 chip is more powerful, it also has a better camera and supports fast charging and wireless charging. 64GB model is not too expensive.

The iPhone 8 Plus shares a powerful foundation with the iPhone 8, but a few features give it a distinct advantage over its little brother. Its 12-megapixel dual camera is one of the best we've used, and its bigger battery makes it last longer than iPhone 8, even the iPhone X. While it's easily the best big phone Apple has ever made, its slightly longer, slightly heavier body make it feel a little unwieldy compared to some of its biggest rivals.

iPhone X has the most impressive features, including a better screen, facial recognition technology and more. Compared with iPhone 8 Plus, iPhone X has a slightly larger screen (5.8-inch), but the iPhone 8 Plus (5.5-inch) is bigger and heavier. The iPhone X is the first iPhone to employ an OLED display, which brings sharper and more vivid images than earlier models, but also the risk of burn-in or image persistence. IPhone X’s camera is excellent, the front-facing camera in the iPhone X now supports Portrait Mode right alongside the rear camera, so you can create Portrait Mode selfies with an artfully blurred background. Face ID works well but is slower than Touch ID, and may not be very stable.

All in all, iPhone X is clearly the future of the smartphone, but not perfect, the future is still under development. It's just a cool new thing, and the 8 and 8 Plus feel great ... a bit boring. So ... Which one do you want?
