The iPhone 8 has a new glass design offering wireless charging. It's faster than ever, thanks to the new A11 Bionic chip, and now comes with 64GB of memory as standard. iOS 11 also brings some cool new features including augmented reality.

The Samsung Galaxy Note 8 is an enhanced version of the S8+. Even thicker and heavier, it's a massive phone and won't be suitable for everyone.

Sony Xperia L1 reviewSony Xperia L1 review
The Sony Xperia L1 offers the biggest screen you'll find on an entry-level or mid-range phone. But that's its only real selling point. Everything else is very ordinary, and the phone is bulky and heavy too. But if it's a big screen you're after, the L1 is worth considering.
