SnapChat
universal
confirmed x ∞
inherent
needless
when used
possible background drain
Causes: screen usage, camera usage, filters.
Workarounds: reduce brightness, don’t have the camera side open unless required, avoid filters
Snapchat is based around using the camera (there is a notable “click” when switching to camera view), and the filters can be CPU/GPU intensive. Historically it has not been programmed efficiently, even though they claim to try to improve it. Since it requires a connection to receive messages it may add background drain, but this is not confirmed yet.
