Samsung Galaxy S23 vs Samsung Galaxy S26+

Our Verdict: Hardware priorities split the decision here, with the Samsung Galaxy S23 strongest for the lighter 167g body versus 190g and the Samsung Galaxy S26+ stronger for the larger 6.7" screen versus 6.1", up to 512GB storage, the larger 4900mAh battery, with the usual caveat that capacity is not the whole battery-life story. The Samsung Galaxy S23 is currently cheaper on the lowest total contract cost at about £209, roughly £587 less than the Samsung Galaxy S26+. There is also much wider deal availability for the Samsung Galaxy S26+, with 14,029 active deals versus 110. That makes the Samsung Galaxy S23 the value-led pick, unless the larger 6.7" screen versus 6.1" on the Samsung Galaxy S26+ is worth paying extra for.

The S23 5G is the cheaper one to own: around £544 over a typical contract, £320 less than the S26+.
