  "account": "Apple Watch Ultra 4 and Ultra 3 share the same external appearance, but the newer model boasts significant internal upgrades. The most notable change is the introduction of the S11 chip, a more powerful version than the S10 in the previous model. While Apple doesn't provide specific benchmarks, it claims S11 to be its \"most powerful wearable chip.\"\n\nApple Watch Ultra 4 also increases its memory from 2GB in Ultra 3 to a robust 4GB, while maintaining the same 4GB RAM in the AirPods Pro 2nd Gen when compared to ultra 1 and 2. The Health Sensing System received a major overhaul in Ultra 4, which Apple claims unlocks deeper health and fitness insights.\n\nThe battery life of Ultra 4 saw substantial improvements as well. It offers 50% more battery life than Ultra 3 and can provide 18 hours of runtime with just a 15-minute charge, compared to 12 hours with the older model.\n\nOne of Apple Watch Ultra's best features, battery life, receives noteworthy gains in Ultra 4. Additionally, the Watch now includes a new feature called Readiness, a health tool that analyzes a user's recent activity, training load, vitals, and sleep score to provide a daily 0-10 score and an actionable recommendation on how to take on the day. This feature helps users decide whether they should recover, pace themselves, go for it, or take it easy.\n\nLastly, Ultra 4 introduces new watch face complications for tracking steps and heart rate, and will support various Audio Intelligence features. These features are expected to roll out through a software update later in the year. Pre-order for Apple Watch Ultra 4 starts at $799 and ships on September 18.",
