The batteries on my 7D lasts usually over 2000 shots. After the last recharge (both batteries) drained in the beginning in a pace that would enable only about 200 shots/battery.
The only change from the last time I used the camera is that I enabled the high ISO noise reduction option.
I disabled this option again replaced the memory card and now I am with 500 shots and 60% of the battery power left.
Did anybody experienced strange behavior of the power indicator, because I doubt that the noise reduction caused the problem.
