Hello Doje. Thank you for sharing your feedback with us. We are sorry to hear the battery life of your new Apple Watch Series 11 is not meeting your expectations. While it features a thin, durable design with up to 24 hours of normal use (Up to 38 hours in Low Power Mode), we want to help you get the most out of it. We highly recommend visiting the AT&T Device Support portal for useful tips to maximize your battery life under 'Maintenance and optimization': 🔗 https://www.att.com/device-support/index/apple/watch-series-11/ If you need further help, please send a direct message to our official channels on X (@ATTHelp), Instagram (@att), or Facebook (AT&T).
