  "account": "The Apple Watch Ultra 4 has been launched alongside several other products such as the iPhone Duo, AirPods 5, and iPhone 18 Pro and Pro Max. There have been no changes in design, pricing, or color options. The watch features a redesigned rear health-sensing system, an S11 chip with Secure Enclave and separate always-on processor, a new Readiness Score, and two new AI features that will roll out later this year. The Ultra 4 also boasts a bigger battery with 5% more capacity compared to the Ultra 3, coupled with efficiency improvements, leading to extended battery life. It can provide up to 50 hours of use in normal mode, up to 84 hours in Low Power Mode, and up to 45 hours in Max Extended Workout Mode. The watch already offers a day or more of use, getting close to two days. A new Apple Watch Charger with faster charging capabilities is included. The watch’s health-sensing capabilities, processing power, battery, and charging have seen upgrades. The author is waiting for more time to judge the impact of the bigger battery and efficiency gains on real-world usage.",
  "summary": "I’ve spent several days with the Apple Watch Ultra 4, and while it looks familiar, the bigger battery, new health-sensing system, HRV, and faster charging are already standing out.",
