The site has compared the wireless charging of the six models – the Galaxy S22 and S23 basic, Plus and Ultra – and has concluded that “the three new members of the Galaxy S23 series charge much slower than the Galaxy S22 series. according to our tests. The worst model to come out of the test is the flagship Galaxy S23 Ultra. The S23 Ultra and S22 Ultra have 5,000mAh batteries and 15W wireless charging, but even with official chargers, the new phone was much slower. The S22 Ultra took 1 hour and 58 minutes to fully charge using the wireless charger, while the S23 took 33% longer at 2 hours and 37 minutes. The phone shows a general reduction in charging speeds that was never reflected in Samsung’s spec sheet. Changes to the base and Plus models from year to year are less relevant, as they also came with higher capacity batteries, so naturally the newer models take longer to charge. The two cheapest S23 models added 200mAh of battery capacity and an extra 15 minutes of wireless charging time.
