Looking for a brand new smartphone? Our best phone ranking is here to give you a definitive answer on the next phone you should buy. We've put together this list from our wide variety of reviews of handsets from a variety of manufacturers in the Android and iPhone space.

If you already have your mobile operating system allegiance set, you may want to check out either our ranking of the best Android phones or best iPhones. If what's on offer in our best smartphone list is a little too pricey for your taste, then you may want to check out our ranking of the best cheap phones

Our best smartphone list has undergone some major changes in the last few months with the introduction of them OnePlus 9, OnePlus 9 Pro, Oppo Find X3 Pro, Xiaomi Mi 11, Samsung Galaxy S21 Ultra, Samsung Galaxy S21 and Samsung Galaxy S21 Plus

This list has seen an almost complete overhaul, plus 2020 saw the iPhone 12, iPhone 12 mini, iPhone 12 Pro and iPhone 12 Pro Max enter this list. There are many more upcoming new phones in 2021 with the iPhone 13, Sony Xperia 1 III, Nokia 10, Samsung Galaxy Z Fold 3 and many more expected by the end of the year. 

We know that it's not all about the high-cost, super spec phones all the time, so we've made you a handy list of all the top smartphones that you can get on the market right now and we assess what really matters to you.

We test these phones rigorously through our review process, making sure that we check every angle and feature - but most importantly, considering whether they've got a decent battery, great screen, strong design and a cracking camera.

Then, perhaps most importantly, we consider the price too. Not everyone can afford (or even wants) a supercar-like handset in their pocket at all times, so we've ensured to give you a full ranking.

The Samsung Galaxy S21 Ultra is our best smartphone in the world right now, and we think it's a fantastic choice for you with one of the best cameras, phenomenal power, great battery life, a solid design and a whole host of other great features.

The Galaxy S21 Ultra isn't a cheap handset, the price is high for this one, but if you're looking for the ultimate smartphone experience in 2021 you will be hard pressed to do better than this latest from Samsung.

Screen: The Samsung Galaxy S21 Ultra features a top 6.8-inch screen with a 120Hz adaptive refresh rate and a Quad HD resolution. This is one of the best smartphone displays on the market.

Battery life: The Samsung S21 Ultra's battery life is solid, and we found it'd often see us through a whole day from a full charge. If you're playing around with the 120Hz refresh rate, battery life is likely to be lesser but it's a top choice if you're after a long lasting phone.

Note the Samsung Galaxy S21 Ultra doesn't come with a charger in the box though, so you'll have to use your existing one or buy one separately.

Camera: Samsung's 108MP camera on the Galaxy S21 Ultra is going to be the highlight for many, and the camera doesn't disappoint on this phone. Like its predecessor, you can take 100x zoom photography, but it's far improved here over the Galaxy S20 Ultra with two cameras working to do the heavy lifting.

Mini verdict: The Samsung Galaxy S21 Ultra won't be for everyone with its high price, but it's the ultimate smartphone you can buy right now taking our crown for the best smartphone money can buy. Be sure to read our full review before making your final decision, but if you're after one of the best overall smartphone experiences we believe you'll find it here with Samsung's latest.
