gpleica Posted January 11, 2010 Share #21 Posted January 11, 2010 Advertisement (gone after registration) On overall battery performance in the M9: It uses power faster than the M8, for sure. Two processors, and bigger files to write. About 75-80% as many shots for me, on average. The scale is also very non-linear - I get 200 shots out of the first 75%, and about 20 shots out of the last 25% before the camera says "Enough!" and shuts down. On the OFF/S/C switch. In-between settings are to be avoided and checked for. The two times I had M8 "temporary sudden death" incidents that required pulling the battery to reboot, it was after I'd found that the switch had slipped to between OFF and S. I've shot a good 12,000 frames with my M9 since receiving it back in late October and I've had the same experience you are talking about, Andy. The last 25% of the battery life is gone within 20-30 shots. Are you shooting compressed or non-compressed DNGs? Quote Link to post Share on other sites More sharing options...

rosuna Posted January 11, 2010 Share #22 Posted January 11, 2010 I expect we'll see an updated camera at Photokina in 9 months. That is possible, but the changes would be minimal. Something you can add to the current model as an upgrade. The M digital cameras need a rethinking. Better components (LCD display, processor), better interface (menus' design, buttons at the back, power switch), better viewfinder/rangefinder (more focus precision, because digital seems to be more demanding), and better power consumption overall. Some of these changes will come from the S2, but others don't. Photokina may be too early for all that. Quote Link to post Share on other sites More sharing options...
250swb Posted January 11, 2010 Share #23 Posted January 11, 2010 And yet with my OEM and Third Party batteries I'm getting about 250 .dng shots in very cold weather, a very linear discharge (sounds painful) according to the meter, and more than 30 shots left at 25%. But there doesn't seem to be much consistency in any of the posts so something fishy is going on. Steve Quote Link to post Share on other sites More sharing options...
chrism Posted January 11, 2010 Share #24 Posted January 11, 2010 Don't forget to condition a battery now and then with a full charge, followed by discharge to camera shutting off (auto power-off must be off for this) then a full recharge. It's the only way to get the best from your batteries. Chris Quote Link to post Share on other sites More sharing options...
jaapv Posted January 11, 2010 Share #25 Posted January 11, 2010 That is true for Nicad batteries, Chris, however for Li-Ion batteries it only serves to shorten the life of the battery. Quote Link to post Share on other sites More sharing options...
chrism Posted January 12, 2010 Share #26 Posted January 12, 2010 True, but doesn't it do something for the chip in the battery that tells the camera about its condition? That was my understanding. Chris Quote Link to post Share on other sites More sharing options...
jaapv Posted January 12, 2010 Share #27 Posted January 12, 2010 Advertisement (gone after registration) Yes and no - with OEM batteries that cannot communicate with the camera it will reset the battery condition meter in the camera. Quote Link to post Share on other sites More sharing options...
250swb Posted January 12, 2010 Share #28 Posted January 12, 2010 True, but doesn't it do something for the chip in the battery that tells the camera about its condition? That was my understanding. Chris Third party batteries need to be fully discharged and then recharged to get the camera meter to recognise they are full. Its because they don't have the OEM chip. But third party batteries are so cheap it doesn't really matter much because they still seem to have a 'long enough' life even with this abuse.
