After jpengland96 many users confirmed having the same or a similar problem, some of them had a battery life shortened by only a few minutes, but user mevans336 had battery life drop by up to 75% while standing idle for 30 minutes. So far apple has not released any official fix for this issues despite so many users protesting about the problem.

After a small investigation I discovered that problem happened mostly after clean install, and according to forum posts removing or upgrading Dropbox helped in getting back around 1.5h of battery life, but that didnt work for all users. Although many users still complain about shorter battery life I found a few that had their battery life increased on average 50 minutes per charge. Based on that we can assume that problem is not solely on new OS X, but probably on some incompatible applications or maybe even piece of hardware.

Just to remind you, apple had similar problems when Lion came out, so we hope that Apple will release fix for this problem as soon as possible, otherwise they will have to face many dissapointed customers abandoning their brand.
