Battery Level Indicator Reliability..??

What is your experience..?? My bodies seem to indicate a much lower charge level availability
than what is truly available.

Thanks

On my 50D the last segment ont eh meter seemed to last forever, on the 7dII, it doesn't last so long, especially if the GPS is on.

It depends on what body. On my X, it's not as accurate as it was on the older bodies like my 1Ds3, 1D2, 1Ds2. Single shot shooting makes the battery level go up and down a few percent. Continuous HS drive uses less battery and keeps the meter more consistent.

It seems that the newer bodies are off by 10% (probably a "reserve"). When I had the firmware problem with the X and was monitoring it with the SDK, the camera would report a value that was 10% lower than what the SDK was reporting.

I don't pay any attention to it until it starts flashing. Then I just stick a new battery in and carry on. Who cares how accurate it is.
