The Samsung Galaxy S23+ is the large-screen model of Samsung's 2023 flagship line, now a strong value buy since the S24+ and later models arrived. Unusually for Samsung, every unit including the UK's uses the Snapdragon 8 Gen 2, so there is no weaker Exynos version to avoid.
The 6.6-inch Dynamic AMOLED 2X runs at 120Hz with a 1080 x 2340 resolution and quotes 1200 nits in high-brightness mode, with GSMArena measuring 1,205 nits and a 1,750-nit peak for HDR, protected by Gorilla Glass Victus 2.
The panel is bright, smooth and flat, with little to fault beyond newer models edging ahead on peak brightness.
The triple camera pairs a 50MP main sensor with OIS, a 10MP telephoto with 3x optical zoom and OIS, and a 12MP ultrawide, with a 12MP selfie camera and 8K video. A dedicated telephoto is a real advantage over cheaper phones.
The 10MP telephoto resolution is modest next to Ultra periscopes, so long-range detail is the clearest limit.
The 4,700mAh battery returned a strong active use score of 13:51 hours in GSMArena's lab, with 45W wired charging quoted at 65% in 30 minutes, plus 15W wireless and reverse wireless.
Charging is quicker than on the standard S23 but still behind the 80W-plus systems on some rivals, the main weak point.
At 157.8 x 76.2 x 7.6mm and 196g with Gorilla Glass Victus 2 on both faces, an aluminium frame and IP68 sealing, the S23+ is built to full flagship standard, in colours including Cream and Lavender.
There is no microSD slot or headphone jack, the usual flagship trade-offs.
The Snapdragon 8 Gen 2 with 8GB of RAM and UFS 4.0 storage delivers full flagship speed, on Android 13 at launch and since updated, with the four-upgrade commitment and Samsung DeX and UWB rounding out the package.
The chip is a couple of generations old now but remains very fast, so performance is not a concern.
Buy the Galaxy S23+ at a discount if you want a big, bright flagship screen with a Snapdragon chip and a full camera set including telephoto, without paying current-flagship money. Buyers who want the newest chip and a sharper QHD+ screen should compare the Galaxy S24+. Buyers comparing contract terms will find current network pricing in the table above.
