New options now see the budget phone available on Three PAYG at £149.99 with a £10 top-up, along with various contract options.

For unlimited data and minutes it costs £28 per month with an upfront charge of £19, but the first six months are half-price. This same deal is available with 4GB of data, at £20 per month wth six months half-price.

Alternatively, for 30GB of data you’ll pay £27 per month, and for 12GB £23 per month, both with the £19 upfront fee.

Confusingly, Redmi Note 9 Pro and Redmi Note 9 Pro Max had already been announced in India – but with different specs. The Indian Redmi Note 9 Pro is in fact the global Redmi Note 9S, while the Indian Redmi Note 9 Pro Max is the global Redmi Note 9 Pro.

The trio offers the best battery performance you’ll find in the budget phone market, with high-capacity 5,020mAh batteries that support fast wired charging. They also have large IPS displays, quad-lens rear cameras and expandable storage, but cut down on costs without luxuries such as in-display fingerprint sensors and wireless charging.

What’s the difference between Redmi Note 9, Redmi Note 9S and Redmi Note 9 Pro

Redmi Note 9 Pro sits at the top of the new line. It has the same processor and display as the Redmi Note 9S, but switches out its 48Mp camera for a 64Mp model, and the 16Mp selfie camera for a 32Mp version. Wired charging is also faster, at 30W against the 9S’ 18W, and the Pro adds support for NFC (available in selected markets only for Redmi Note 9 and Redmi Note 9S).

The Redmi Note 9 is the cheapest model in the trio. It achieves a lower price by reducing the display from 6.67in to 6.53in, moving the fingerprint sensor from the power button to the rear, and reducing the memory and storage options from 4GB/6GB and 64GB/128GB to 3GB/4GB and 64GB respectively. The Snapdragon 720G processor has also been swapped out for a MediaTek Helio G85 chip, and while the Redmi Note 9 uses the same 48Mp camera as the Redmi Note 9S, the specs for some of the additional lenses and selfie camera have been reduced.
