The once-affordable OnePlus's 2021 smartphones come with prices that put them firmly in the premium category. But with the announcement of four years of security updates, they might just be worth it.
Read on to see all the features on the new OnePlus flagships and how its security support compares with other leading brands.
OnePlus' latest flagship looks, at least on paper, like a real contender to the big brands. It hopes to tempt you away from the likes of Samsung Galaxy and Google PIxel with some premium features, most notably wireless charging, 8K video recording and IP68 waterproofing - which means your phone should survive a dip in water up to 1.5 metres deep for up to 30 minutes.
You also get high-resolution cameras - a 40Mp wide, 50Mp ultra-wide and 2Mp monochrome lens on the back, plus a 16Mp selfie camera. There's enough room to cram a hefty 4,500mAh battery in the 6.6-inch frame, and you get a beautiful OLED screen, too. The high 120Hz refresh rate should help your videos to display beautifully and minimise annoying jitters while you're scrolling.
There's plenty of computing power, with Qualcomm's advanced Snapdragon 888 processor backed up by a hefty 8GB of Ram. You can't extend the 128GB of storage, although it's enough that you hopefully shouldn't need to.
The OnePlus 9 Pro is the priciest phone at launch that OnePlus has ever announced - beating last year's 8 Pro by £29.
On the surface, there isn't much to differentiate this model from the cheaper OnePlus 9. There's the same amount of internal storage, an equally sized battery, the same premium added extras (waterproofing and wireless charging) and, unusually, there's no upgrade to the processor or Ram on this premium version.
Changes come on the display (the Pro has an extra 0.1-inch on the 9, the addition of curved sides and a higher display resolution), and an additional telephoto lens on the camera setup. It might not sound like much, but we've seen excellent results from tele lenses in our test lab, particularly in retaining detail while zooming, so we'd expect great things from this model.
We were intrigued by the N10 5G when it launched late last year. It stood out in its price bracket thanks to the addition of 5G, 6GB of Ram and a 64Mp main camera, although the news that OnePlus would only send updates for two years somewhat dampened our excitement.
However, it's not just OnePlus's pricier phones that will benefit from longer support periods. It's also announced that the Nord series, including the N10 5G, will be updated for three years - putting this phone firmly back on the map if you're shopping for a budget handset.
It offers 128GB of internal storage (which can be extended via the micro-SD card slot), and unlike OnePlus's very cheapest phones, it's equipped with near-field communication (NFC) so you can use it to make contactless payments.
If you want to buy a phone that's built to last, you'll have to consider the issue of security updates. These vital patches are delivered via notification for you to download and keep your phone secure, but they don't last forever.
We've long highlighted the problem of short security update cycles, with some lasting for just two years. That's after their launch, too, not the day you buy it, so you could find yourself using an unsupported phone
The length of support is based on the brand you pick, so choose wisely - and bear in mind that the cheaper brands (and some budget handsets from pricier ones) are likely to have shorter update periods.
