Actual battery life will vary based on the use environment. For instance, there is a difference in battery life when the gimbal operates in leveled or non-leveled use. Non-leveled use will require more power and therefore give you less battery life. The official laboratory test environment only includes the battery life under the ideal leveling state, which is for reference only.
It is recommended that users try to level the phone and use it to get a longer battery life experience.
