Flagship phones

Samsung Galaxy S21 Ultra 5G

Specs

The Galaxy S21 Ultra gathers all the cutting edge tech Samsung can offer to the public, short of a foldable screen. A quad camera with advancements all around, a superb display with all the bells and whistles, including S Pen support, class-leading battery life - there's hardly anything missing.

Flagship killers

Xiaomi Poco F3

Specs

The Poco F3 is one of the hottest surprises this season. It's a proper flagship-killer, the catchy name behind all those overqualified mid-ranges. The F3 impresses with a 120Hz AMOLED screen and the second-best Qualcomm chip right now - the Snapdragon 870 with 5G.

Camera phones

Xiaomi Mi 11 Ultra

Specs

Breaking a streak of Galaxy title holders, the Mi 11 Ultra is our latest Editors' choice for cameraphone. It packs a unique combination of top-class hardware and puts it to good use, producing great results across virtually all scenarios.

Gaming phones

Asus ROG Phone 5

Specs

Nobody does smartphone gaming quite like Asus. Four iterations into the ROG Phone line, that remains a fact. The ROG Phone 5 is a true powerhouse in every sense of the word - a phone that is specifically crafted to deliver the best possible gaming experience, with any other concern or consideration taking a back seat. It just so happens that when you make an excellent gaming flagship, you usually end up with an excellent all-around device in general that has plenty of appeal outside gaming.

Battery life champions

Xiaomi Poco F3

Specs

The most recent Poco F3 replaces our previous top pick for a battery life champ - the Poco F2 Pro. It is currently one of the most powerful smartphones and the most dependable performer when it comes to battery life.

Compact phones

Apple iPhone 12 mini

Specs

We sure thought Apple was done with the small iPhones this year after the new iPhone SE premiere. Yet, Apple managed to surprise us with a proper mini flagship with no missing features. Indeed, the new iPhone 12 mini is a smaller version of the iPhone 12 and it's lost nothing.

Premium all-rounders

Motorola Moto G100

Specs

The Motorola G100 is replacing our previous Motorola pick for this category - the Moto Edge. It offers nice perks such as a smooth 90Hz LCD screen, one very powerful Snapdragon 870 chip and Ready For (DeX-like) desktop capabilities.

Midrange all-rounders (up to €300)

Xiaomi Redmi Note 10 Pro

Specs

There is no better mid-ranger than the Redmi Note 10 Pro if your budget is around the €300 mark (MSRP of €279). The phone offers excellent screen and camera quality, plus splash resistant glass design . Its chipset may not be the fastest, but it's up to par.

Midrange all-rounders (up to €250)

Xiaomi Poco X3 Pro

Specs

The €220 Poco X3 Pro is easily the best phone around the €250 mark. It has a large 120Hz display and one enormously powerful (for the class) Snapdragon 860 chipset with plenty of RAM and storage. The phone is IP53-rated for splash resistance and offers Gorilla Glass 6 screen protection.

Midrange all-rounders (up to €200)

Xiaomi Poco X3 NFC

Specs

There is no better mid-ranger than the €189 Poco X3 NFC if your budget is around the €200 mark. It was, in fact, our previous top pick for the €250 category, but now it's even cheaper!

Entry-level phones

Xiaomi Redmi 9

Specs

Our top pick to buy in the most affordable category is the Redmi 9. It is a great budget smartphone with a large 6.53" 1080p screen and powerful enough Helio G80 chip. It has four cameras on its back - wide, ultrawide, macro and depth.
