A method for power optimization for a dual camera imaging device, the method comprising: selecting a zoom factor by a user for capturing image data; determining a zoom factor range that the zoom factor selection falls within; in response to determining that the zoom factor selection is within a first zoom factor range [1.0x,Mx-Bx], providing a series of frames of a scene from a first sensor; in response to determining that the zoom factor selection falls within a second zoom factor range [Mx-Bx,Mx+Bx], providing the series of frames of the scene captured by the first sensor and providing the series of frames of the scene captured by the second sensor; in response to determining that the zoom factor selection is within a third zoom factor range [Mx+Bx,Fx], providing a series of frames of a scene from a second sensor; determining a field of view (FOV) ratio (M), wherein the FOV ratio is a ratio between the FOV (1.0) of the first sensor and a FOV (F) of the second sensor, and the FOV ratio (M) is less than the maximum zoom factor (F) of the imaging device; determining a buffer factor (B) based on a warm up period of the second sensor, wherein the first [1.0x,Mx-Bx], second [Mx-Bx,Mx+Bx], and third [Mx+Bx,Fx] zoom factor ranges are determined using the buffer factor (B), the field of view (FOV) ratio (M) between the first sensor and the second sensor and a maximum zoom factor (F) of the imaging device; and turning off one of the first and second sensors when the other of the first and second sensors is sending frames to a camera application when the zoom factor is within either of the first [1.0x,Mx-Bx] and the third [Mx+Bx,Fx] zoom factor ranges. selecting a zoom factor by a user for capturing image data; determining a zoom factor range that the zoom factor selection falls within; in response to determining that the zoom factor selection is within a first zoom factor range [1.0x,Mx-Bx], providing a series of frames of a scene from a first sensor; in response to determining that the zoom factor selection falls within a second zoom factor range [Mx-Bx,Mx+Bx], providing the series of frames of the scene captured by the first sensor and providing the series of frames of the scene captured by the second sensor; in response to determining that the zoom factor selection is within a third zoom factor range [Mx+Bx,Fx], providing a series of frames of a scene from a second sensor; determining a field of view (FOV) ratio (M), wherein the FOV ratio is a ratio between the FOV (1.0) of the first sensor and a FOV (F) of the second sensor, and the FOV ratio (M) is less than the maximum zoom factor (F) of the imaging device; determining a buffer factor (B) based on a warm up period of the second sensor, wherein the first [1.0x,Mx-Bx], second [Mx-Bx,Mx+Bx], and third [Mx+Bx,Fx] zoom factor ranges are determined using the buffer factor (B), the field of view (FOV) ratio (M) between the first sensor and the second sensor and a maximum zoom factor (F) of the imaging device; and turning off one of the first and second sensors when the other of the first and second sensors is sending frames to a camera application when the zoom factor is within either of the first [1.0x,Mx-Bx] and the third [Mx+Bx,Fx] zoom factor ranges. <EOS>
