Just having it installed will NOT use your battery. The battery will not be used when the application is turned off.

Sekai Camera uses many sensors when activated, so it requires a relatively large amount of battery power when it is in use, especially in Liveview mode.

If you are planning on using Sekai Camera for an extended period of time, we recommend the use of extra batteries.
