Overview

The Honor 400 Smart has one of the biggest batteries you’ll find in a budget phone – and it’s also higher capacity than most high-end phones, at 6,500mAh. With that, you can potentially get days of life, and this battery won’t wear out fast either, with Honor’s tests finding that it should retain over 80% of its capacity after five years.

It also charges fast, at up to 35W, all of which is good because this is a phone you’ll probably want to use a lot – especially if you’re a fan of AI, as it has a dedicated AI button.

This button will give you smart recommendations related to what’s on your screen if you long press it. So, for example, if your screen is showing a picture of a dog, then a long press might tell you the breed and provide an option to share the image. But if instead you simply tap the AI button, then you’ll be shown shortcuts to all sorts of apps and tools.

The Honor 400 Smart is also dust proof and resistant to water splashes and drops, so it’s more durable than most budget phones, and it has a dual-lens camera, with a 50MP main sensor and a 2MP depth sensor. That combination – coupled with AI photo editing tools – allows you to capture and create some striking images.

It also has a large 6.77-inch 120Hz screen with handy features like an eye-friendly low blue light mode, plus a capable Snapdragon 6s Gen 3 chipset, 5G support, and impressive dual speakers, which have a remarkably loud high-volume mode.

With a slim 8.4mm thick build in a gorgeous Velvet Black colour scheme the Honor 400 Smart is a stylish handset too, and it comes in at a highly affordable price.
