Strange how no real users report issues with Mountain Lion battery life. All seems to be these mysterious internet people with unknown affiliations to other tech companies.

Funny how some people don't notice threads on Macrumors and think its just mysterious Internet people.

I have not seen any problems whatsoever in regards to battery in neither Lion nor Mountain Lion. This experience is based on two MacBooks and two MacBook Airs.

It may not be a case of mysterious Internet people, but of the apps they install. People writing reviews for websites will undoubtedly have many apps installed and have tinkered with their systems. When someone from a reputable site opens a MacBook straight from the box and sees battery problems, let us know.

THis is what's strange about this problem;

1. Many never see it
2. Many saw it going from Snow Leopard to LION
3. Some Saw it going to ML from SL or ML
4. The MAC itself doesn't indicate anywhere what the cause is (the strangest part). If there's a "rouge" program - why does it run fine on some o/s's and not others?
5. Some people can fix (temporarily) with the usual SMC/PRAM resets (without changing anything else)
6. Some can downgrade and fix their problem.

The pattern is in the few patterns. If Apple did a better job of telling your where your resources were going then all would be well. MY Android S3 tells me who's using the battery so I guess the MAC could do!!

And yes, even people with new machines.

I love how the second article says that zapping the PRAM requires not only confidence, but a good bit of finger dexterity, lol.

I am a real user, and I have had horrible battery life on my 2011 mba 11", but thanks for making me feel like i dont exist. It's bad enough automatic door openers dont open for me, and now this...

I had huge battery problems on my old MBP, moving from SL to L.
No problems on my 2012 Air, moving form L to ML.

I notice that my battery cycle went to two counts in a day well that's a lot . Before ML my battery cycle is once a day and I am using the MBA with normal usage.

It's probably because Mountain Lion only displays the battery life in percentage now. To view it in time you have to do additional steps that most people aren't bothered to do.

nope its not because of the percentage . coz when you talking about battery cycle it really cycles faster than before ML>

Not to mention the fact that PRAM/NVRAM has nothing to do with battery/power/charging issues. Resetting it will not help. Only resetting the SMC (http://support.apple.com/kb/ht3964) addresses such issues.

It's probably because Mountain Lion only displays the battery life in percentage now. To view it in time you have to do additional steps that most people aren't bothered to do.
To view the time, just click the icon on the menu bar. That's hardly enough work to be called "additional steps". This is already being discussed in several threads:

Battery - Show Time no longer available (http://forums.macrumors.com/showthread.php?t=1397566)
From the CHECKING STATUS AND HEALTH section of the following link:
On the MBPR and on ML, the Menu Bar battery indicator no longer offers "Time Remaining" as an option on the Menu Bar. It still appears in the dropdown menu.
You can use this app to get the same functionality: SlimBatteryMonitor - Battery and UPS Gauge for Apple's Mac OS X (http://www.orange-carb.org/SBM/)
From the BATTERY LIFE FROM A CHARGE section of the following link:
Your "time remaining" indication is an ever-changing estimate, based on the current workload of your system. It will fluctuate up and down from minute to minute as your power demands change. It is not perfectly accurate, but only an estimate.

There are many factors that impact your battery life. See the BATTERY LIFE FROM A CHARGE section of the following link for details, including tips on how to maximize your battery life.

This should answer most, if not all, of your battery/charging questions:

Weird...I thought I was having this exact same problem (http://forums.macrumors.com/showthread.php?t=1412236). I'm glad you cleared things up that no "real" people are having these problems. I guess my 1-3% battery drain per minute on ML must be, like myself, a mysterious thing with no affiliation to anything real. :rolleyes:

That wasn't sarcasm. Which makes your rude response all the more ridiculous. It didn't even resemble sarcasm. I take it you're American? ;)
