Samsung Galaxy S21+ 5G review

GSMArena Team, 5 February 2021.


Almost as big as the Ultra, but not quite as camera-centric. Nearly identical to the vanilla, but with a plus-size screen, extra battery and a more premium touch. Yes, we're talking about the middle option in the 2021 Samsung S-series roster, the Galaxy S21+.

Plus stands for 'more of it', and the S21+ has a bigger display - at 6.7 inches in diagonal, it's a lot closer to the Ultra's 6.8 inches than it is to the S21 proper's 6.2. Beyond the size, however, it's more vanilla than it is Ultra - the resolution is 1080p, and the Adaptive refresh rate handling is the half-there variety, but Adaptive it is nonetheless.

There's 'more of it' when it comes to battery capacity, and here, too, Plus aims for the Ultra - at 4,800mAh, it's oh-so-close to the 5,000mAh of the top model. More importantly, perhaps, the middle option is the only one that's gotten a battery upgrade this year.

The third area where the Galaxy S21+ differs from the S21 is the build. And here, from the vantage point of the S21+, the choice of plastic for the S21's back makes sense - this way, the Plus has one more thing going for it. Maybe.

We touched upon the differences between the S21 and S21+, two out of three of those quantitative, the other - well, qualitative. Here's a reminder of the other bits that make up the S21+.

Samsung Galaxy S21+ unboxing

The Galaxy S21+ arrives in the same half-height box as the other high-end Galaxies for 2021 and, likely, from here on. When you don't pack a charger and headphones, there's no point in wasting cardboard, is there?

Samsung Galaxy S21+ 5G review

We're not strictly against the disappearing chargers trend. There are charging stations in the office with QuickCharge 3.0 outputs, and those have been serving us well for several years now and will continue to do so. Additionally, between us, we've bought an assortment of USB Power Delivery adapters for personal use and the bulk of us likely fall in that group of people who won't be needing new chargers with their next phone purchase. So there could be actual benefits to this, eventually. Perhaps the way the marketing teams have been sugarcoating the process is what's been most annoying. Anyway, on to the design.

Greeting I use s21 and I have a problem with contacts. The contacts have been saved on gmail for over 10 years and whenever I changed the phone I always synced and everything was ok, now I haven't changed the device recently but the contacts ...

Is this a worthy upgrade from s20fe 5g

The battery life isn't so bad because I do serious gaming with it and it lasts about 7 hours of nonstop gaming I'm using the snapdragon variant
