What are the charging time for both Apple Watch series 8 and Apple Watch SE
Apple Watch with original charger supports faster-charging bro. For my Series 7, it took 1 hour 15 mins from around 10%. And with Ultra, it almost takes the same time or sometimes fast charging does under 1 hour.
As apple watch has optimised charging feature, charging speed adjusted and there is no exact time measurement for any apple watches at present.
