Battery Life
Equipped with a removable 1500 mAh battery, the Samsung Omnia M provided reasonable battery life, claiming up to 530 hours on standby and up to 12 hours and 40 minutes of talk time on a 2G connection, with slightly reduced times on 3G. The battery performance was sufficient for a day of moderate use, largely due to the efficient nature of the Windows Phone operating system and the relatively low power requirements of its hardware.
