Yes. I like the 7Hi very much but the battery consumption is quite scarry.
Initially I used the Sanyo and realised it does not last very long... then I bought the Energizer and it is better but still not enough. Very fed-up with this, I did some review and bought a powerbank and it is great ! It last 1 whole day with LCD shooting. The power retention is also great if not in used and it can retain for more than a month :bigeyes:
