A base button steps through five heat settings that span 125°F to 145°F, and the app stays available for finer tuning. The sliding lid extends battery life to more than three hours per charge and helps curb spills, while the redesigned mug is now top-rack dishwasher safe. Starting at $129.95, the Mug 3 makes [premium temperature control](https://www.trendhunter.com/trends/pixelmug) easier to live with day to day. On-mug controls and dishwasher-safe cleanup broaden its appeal beyond app-led gadgets to buyers who want [hot coffee or tea](https://www.trendhunter.com/trends/cuptone-teacup) with less upkeep.
