A fix is likely coming soon for your overheating Samsung Gear S3
According to users on Reddit as well as Sam Mobile, it appears that Samsung is performing a slow rollout of a new Tizen update to Samsung Gear S3 smartwatches. The update addresses a widely-reported charging and overheating issue.
After updating to Tizen 3.0 (the proprietary, Linux-based OS for Samsung smartwatches), some Gear S3 owners reported a troubling problem: Gear S3 watches would overheat while on the charger, never fully reaching 100 percent capacity.
Instead, watches would get to 90 percent charge, then begin overheating. Users could remove the watch from the charger to cool off, then place it back on the charger where it would then finally fill to 100 percent.
Best smartwatches (June 2018)
Smartwatches are still a very new thing to a lot of people, and for good reason. You don’t absolutely need one to get through the day, and some of the best smartwatches are much too expensive …
While not exactly a debilitating issue, it’s certainly not ideal for charging purposes, and the constant overheating could drastically affect the longevity of the watch.
It looks like Samsung is pushing a new 16MB update to Tizen 3.0 with a build update of R760XXU2CRG3 for the Samsung Gear S3 Frontier and R770XXU2CRG3 for the Samsung Gear S3 Classic. The changelogs for both updates mention adjusting battery-charging algorithms to address this overheating problem.
While many users worldwide are reporting receipt of the update, it is not clear if Samsung is, in fact, performing a full rollout. As such, it might be some time before you see the update. In the meantime, you can manually check for updates on your Gear S3 by opening the Gear app and going to Settings > About Gear > Update Gear Software.
