1 16 hours of battery life is approximate and is based on testing conducted in California in 2023 on pre-production hardware and software, using default settings across a mix of talk, data, standby, and use of other features. Battery life depends on features enabled, usage, environment and many other factors. Use of certain features will decrease battery life. Actual battery life may be lower.
