Many people around the web have complained of issues with battery life after installing the Yosemite update – in fact a Reddit discussion has been devoted to it. As one user shared,

“I'm on a 2014 MacBook Air 13 inch and the battery seems to drain noticeably faster. When I'm doing simple tasks such as web browsing and playing music, the battery seems to go down quite a bit faster then before. Has anybody had any issues like this?”

To which another added,

“Same problem here. Charged to 100% two hours ago, and I'm sitting at 64% right now, whilst barely having touched the computer (checked my mails and went on FB for about half an hour). Now it says I have approximately 4 hours of battery life left.”

The Fix:

If you are also experiencing a problem with battery life on Yosemite, fortunately a user on Reddit was able to offer an explanation and a reassurance that it’s only temporary.

According to Redditor, seraphls

“Whenever you do a major update, the battery needs to recalibrate and Spotlight needs to reindex. It takes a day or two, and battery life bounces right back.”

So for all those fearing that bad battery life is the tradeoff for Yosemite’s new features, don’t worry. That problem should remedy itself shortly.
