Neither Samsung Galaxy Watch5 nor Galaxy Watch5 Pro recharge as fast as advertised

Samsung advertises the Galaxy Watch5 series as featuring a new fast charging feature. Theoretically, the Galaxy Watch5 and Galaxy Watch5 Pro should recharge 0-45% in just 30 minutes. However, an independent test has shown that this is unachievable in practice. Instead, new owners of either smartwatch should expect to wait a lot longer for either smartwatch to reach 45% charge, let alone full charge.

It seems that Samsung has included other misleading information in its Galaxy Watch5 and Galaxy Watch5 Pro listings. As we discussed yesterday, neither the Galaxy Watch5 nor the Galaxy Watch5 Pro are as thin as Samsung advertises. Instead, the Galaxy Watch5 Pro is over 40% thicker, with Samsung deciding against including the smartwatch's entire back panel in its measurements. Also, SamMobile has demonstrated that neither smartwatch matches Samsung's advertised charging speeds, either.

For context, Samsung states that both models should take 'about 30 minutes to go from 0% up to 45% charge'. In comparison, Samsung did not even boast about the charging capabilities of the Galaxy Watch4 or Galaxy Watch4 Classic. Supposedly, 30 minutes on Samsung's official charger only gets the Galaxy Watch5 and Galaxy Watch5 Pro to 36% and 30% charge, respectively. In other words, the pair offer approximately 20% slower charging speeds than Samsung advertises.

Based on our tests with the smaller 40 mm model, the Galaxy Watch4 takes approximately 1:45 hours to recharge fully. According to SamMobile, the Galaxy Watch5 recharges faster despite having a larger battery, although it still takes nearly 1:30 hours. By contrast, the Galaxy Watch5 Pro needs over 2 hours on its charger before it reaches 100%.

Samsung notes that it achieved its results with the Galaxy Watch Magnetic Fast Charging USB C Cable (EP-OR900) and the Samsung 25 W USB Type-C Power Adapter (EP-TA800). SamMobile performed its tests with a Samsung-branded 45 W charger, so it seems that Samsung's caveat of 'environmental factors' affecting charging performance could be particularly true in this case.
