Every once in a while, some major OS vendor removes a really useful feature.
As of OS X Mountain Lion (10.8), the battery icon indicator cannot show the remaining time on battery any more, though it uses that time to indicate low power.
I’ve found that feature really useful in Lion (10.7) and Snow Leopard (10.6), and I’m pretty sure OS X versions before that also had the option to show the remaining battery (charge) time.
There is a big thread about the lack: Time remaining on Mountain Lion battery: Apple Support Communities.
A quick scan in that thread got me a these replacements:
- SlimBatteryMonitor – Battery and UPS Gauge for Apple’s Mac OS X. (free)
- Battery Time for OS X. ($ 0.99)
- Mac App Store – Battery Guard. (free)
- iStat Menus, a Mac app by Bjango. ($ 16.00)
- codler/Battery-Time-Remaining · GitHub. (open source)
I hope the $099 one is not written by the people that removed the feature from OS X Mountain Lion (:
After trying a few of the above, I filed a complaint at Apple – Mac OS X – Feedback, clicked on “I have this question too” in Time remaining on Mountain Lion battery and went for SlimBatteryMonitor as it uses the least menu bar estate.
Note that for most applications having icons in the menu bar, this is impossible: osx – Can I change the order of non-apple icons on the menu bar of my MacBook? – Super User.
