Galaxy Watch 9 Charging Stretches to 4 Hours as Users Fight Thermal Throttling
1 articles · Updated · Android Authority · Aug 12
Summary
Galaxy Watch 9 and Watch Ultra 2 owners say full charges are taking 2 to 4 hours, far beyond Samsung’s advertised 80- to 90-minute times.
Charging power appears to fall from about 5.5W to 3.5W or lower as heat builds, with users blaming aggressive thermal throttling for the slowdown.
Reddit and Samsung forum posts show some owners using desk fans, metal mounts and even ice-assisted setups to keep charging speeds from collapsing.
Charger issues may be compounding the problem: some Watch 8 and third-party docks trigger slow-charging warnings or fail, while a few users report older Watch 6 pucks work better.
Samsung had not commented at publication, leaving early adopters waiting for clarity on the cause and any firmware fix.
