Documentation
Actual size and weight vary by configuration and manufacturing process.
All battery claims depend on network configuration and many other factors; actual results will vary. Rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced by an Apple service provider. See http://cms/iw-cc/Site/Component/ for more information. For more details of iPhone performance tests for talk time, standby time, Internet use over 3G, Internet use over Wi-Fi, video playback, and audio playback, see http://cms/iw-cc/Site/Component/.
