I didn't update from lion till 10.8.2 was released .
40% brightness \no Bluetooth\no keyboard light \ just opening safari give me an estimated of 5:30 that starts to dwindles rapidly.
on lion i used to get about 9 hours under same conditions guess I'm going back to lion soon.
so anybody with retina here could provide feedback please

Ps: base rMBP \clean install \SMC reset \ Indexing was done .

same experience here and i don't own a retina.

i used to get up to 7/8 on Lion, and maybe even 10.8.1 sometimes.

now a full charge start at 5:30 with the same settings as you: brightness half way, no bluetooth, low or no backlight keyboard.

basic apps running.

I've just reverted back to lion .While It seems I don't get the previous battery life for some unknown reasons but It is almost certainly better than ML.

I'm experiencing similar issues. On 10.8.1 I used to get solid 8 + hours in actual battery life. On 10.8.2 it's down to about 5 1/2 hours.

That's on a rMBP, 8GB RAM, 265 SSD - base model.

I'm starting to get frustrated with Apple's slack approach to software maintenance and their hardware issues. One of the biggest problems I experience is the image retention. Unfortunately I do not live in a country with an official Apple store. Therefore an exchange / repair / replacement will take several days - if they accept it at all. That's just not feasible if you rely on your machine.

i'm not sure about apple's hardware though i'm very surprised they can release a product like that, i don't usually say it but i would be surprised if steve jobs wouldve allowed that, i would think he wouldve given that a pass and told them to wait for the GPU's to catch up.

but as far as OS's go, i don't see Apple being like their former self, or windows anymore. they have changed their target market, its clearly more a consumer audience they are selling for. Pro market seems alienated more now.

Mac OS is no longer looked at as a Necessety of computers and productivity in the sense of it being an OS thats designed to be Stable and reliable to work on for years.

no.. its quite different model now. apple has adopted the iOS format:

release yearly updates with new consumer features to the OS, at the cost of stability, long term reliability. from now on it will be a rollercoaster ride of new and arguably desirable features, in exchange for the inconsistent performance, and unreliable experience of the OS.

on my macbook pro late 2011.

57% battery left and the timer is at 1:50h. the battery life on 10.8.1 was a little bit better but also not as good as in lion.

hope they get to fix that soon.

Battery life roughly increased by 1,5 to 2h (right now showing 79% capacity which means 5h 34min runtime left with Mail, Safari and iPhoto running).

You battery watchers need to time the actual usage you get and stop relying on the ever-changing time that is displayed. It's just a guess.

WTH :confused: ?? How can :apple: be on the third incremental release of OS X 10.8 / ML, with significant time transpiring between incremental releases, and still not have this battery life / battery meter issue resolved ?? Surely :apple: did not sell the OS X group to Microsoft ... I mean, really ... right ?? ... right ??

I develop embedded hardware and firmware for a living and I can't imagine us getting away with this ... our customers would cut us loose. When you ( :apple: ) control every aspect of the hardware design from the chips on up and you ( :apple: ) control every aspect of the boot firmware and the software ... well, I don't need to say it, I think you see where I'm going.

Unacceptable ... BMA57

After the 10.8.2 upgrade (and waiting for mdworkers etc to finish their business), a fully charged machine showed 5:20 on unplug.

After the battery calibrate (i.e. let battery run all the way down to point of hibernation, and then fully recharge), it now shows 7:25 on unplug.

Early 2011 15" mbp 2.2/8G/256Gb SSD/hi-res

...so, moral of the story, run a calibrate, yo!

That sounds fine and dandy but how much time did you actually get?

1.) Charge to 100%, start machine
2.) Look at clock on the wall - write down what you see.
3.) Use mac until hibernate
4.) Look at same clock again
5.) Subtract step 4 from step 2

:D

Seriously. This is the only way to measure battery life.

Simply draining and recharging the battery is NOT calibration. Also, the built-in batteries in the newer Mac unibody notebooks come pre-calibrated and do not require regular calibration (http://support.apple.com/kb/HT1490) like the removable batteries in older Apple notebooks.

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.
The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.

Hi,

I was happily using snow leopard, on a 13 inch mid-2009 mbp (Bought in early 2010) with 2.53 ghz and 4 gb ram.

3 or 4 days ago I decided to upgrade to Mountain Lion.

Computer got hotter than usual, running fans and so forth, till I spotted a "service battery" alert and noticed my battery was going low very very fast. I used coconut battery and found out it was at half its design capacity. Naturally, being my computer 2 years old, I didn't expect it to be that fresh, but it certainly was doing much better a few days before. much much better.

I saw online other people had had similar problems but I couldn't spot a precise solution (smc reset didn't do anything).

I took it to the apple store (I live in shanghai)

They were not aware of similar problems, so, although I'm on apple care, I had to pay to get a replacement battery, because batteries only have one year warranty. I wasn't delighted by this.

I'm home now, my computer is getting quite hot while I'm not doing much, and I seem to notice it goes down fast. I checked on coconut battery and it's already telling me that the battery is at 98% of its design capacity.

What do I do? Do I have to go back to snow leopard? I'm reinstalling Mountain lion, but I hat having to do a clean install..
Is there a way I can get this fixed and also complain about having had to pay 16$ for a software that fries my battery that then I have to replace with another 100 and more $ from my own sorry pocket?

Sorry, this was a little long..

The estimated time remaining is a pretty useless feature that does not tell you much. Have any of you actually tested your REAL battery life instead of looking at the battery remaining estimate? It works like the instantaneous fuel consumption that you see on some cars, where apparently quite often I am getting about 2 mpg. Yet my average consumption is a totally different figure. That's what you should be looking at. Unfortunately the only to test that is to actually see how long the battery lasts.

Girolamo, I have the very same problem. 2008 Macbook Pro, new (!) battery that I bought < 2 months ago at Apple Online and the battery was working absolutely fine until I upgraded to Mountain Lion from Snow Leopard last weekend. Since then the 'battery health' keeps jumping from 95% down to < 50%, then up to 64% and back to now 93%. One time the macbook was not booting and the battery showing completely empty after 20 minutes of use, attaching the charger back "recharged" the battery within 20 minutes, which is impossible. Right now the battery shows 100% but remains charging... Ridiculous.

Called Apple support today, I had a bootable backup of Snow Leopard and (at least) the battery health shown in there is the very same (95%).

I suspect it is a software issue, will call support tomorrow again to see what they say.

The battery was working completely fine until I upgraded to ML (and I waited til 10.8.2 was out..), oh well..:mad::mad::mad:

I am really curious if
-) the battery can be somehow corrupted via ML
-) if just ML has bugs regarding battery life.

Anyways, this is no OS that should be released to customers in this form, imho.

p.s.: and yes, I reset pram and smc.

I was told that Apple is still looking into issues regarding ML and batteries, still at 10.8.2 too.

Hey, thanks,

My battery is going down fast and steady, I replaced it 3 days ago and I'm already at 95% of its maximum capacity, and I haven't used the computer a lot.
I'll wait for another couple of day, then I'll take it to the apple store again, and see what they have to say this time. This battery is under warranty, i really want to see now if they feel like giving me another battery, which will then be sucked again in a week and will have to be replaced and so forth...
I'll keep updating this.

It is perfectly normal if your battery health (maximum capacity) is more or less than 100%, even when brand new, or if it fluctuates up or down over time. For further details, read the CHECKING STATUS AND HEALTH section of the following link.

Thanks for the helpful link. I knew that the "battery health" can fluctuate, but it is not normal to fluctuate for 50 or more percent, and a 2 months old battery should not fluctuate down to 3%.

Will report if it happens with the new battery, too (hopefully not)!

My post about that was in response to another post, which I quoted, not yours. Certainly 3% health is not normal.

I waited until 10.8.2 to upgrade from Lion because of the battery issue. I have a MBP 5,1 15" with an SSD/8GB Ram and a brand new battery from the mac store a month ago. Prior to the upgrade I was getting 5.5 hours and now I have dropped 10% in the last 10 minutes AFTER calibrating. In the process of running down the battery with just safari running it took nearly 5 hours. So I am not sure if the battery life has been depleted or if the software estimate is just way off. Guess I'll have to time it with a stop watch to see the actual battery life and report back.

Hey guys. I did a clean install of Mountain Lion from Snow Leopard.

On Snow Leopard, I got 6-7 hours with normal usage.

With Mountain Lion with the same uses, I get 3-4.

This is kind of ridiculous.

If the situation was serious I would have known of it.
I think it is just the applications you run, possibly your iCloud acting and etc causing poor battery life.

I've got this problem too. I have just notised it. The battery is showing me the "service battery" message.
I have upgraded to ML few days ago and now I see that I am loosing 1% of battery every 2 (or less) minutes. Damn what the ****!
I ve got 2011 Macbook Pro 15'.

that is how ridiculous the drop is on my mbp5,3. unplugged at 16h55 when at 100%. by 18h05, I had 8% left.

Does anyone of you have NTFS programs/driver installed?

Mine 3g driver is at 50% load whenever I'm downloading things form the internet, even with small bandwidth. I always have to add my bootcamp partition into the Spotlight exceptions to reduce this load.

When I do this, my battery will last for up to 8-9 hours on normal use and 12+ at night when I dim the screen.

My battery time on Air has improved dramatically with 10.8.2 ... Depends what I'm doing of course, but for the first time it is saying battery health 100 percent, rather between 95 and 99, and time when fully charged 8 to 9 hours whereas was best about 5 or so before.

While I do check on this and other things in iStat etc, I am also following advice from someone here in not being too concerned with it.

Are you downloading directly to an NTFS drive? If you're on Mac OS X, most users download to the Downloads folder, which is usually on the HFS+ drive, so NTFS drivers shouldn't be involved.

You might consider uninstalling/reinstalling NTFS-3G or try Paragon (http://www.paragon-software.com/home/ntfs-mac/).

Well, Mountain Lion is 3 months old so don't make a quick decision and downgrade to Lion. At least wait until 10.8.3 is out. It should be out in 2 months or so. I know it is a pain in the ass, but please be patient.

What exactly do you do on your computer to get 9 hours? I can get 7-8 hours on my retina Macbook if I just surf the internet lightly. That means no youtube videos or sites with flash. In addition to that it means I am also staying on the page or site for longer periods of time. I also have my brightness set to 50% and my keyboard to 33% brightness.

I don't use any other apps in the background like itunes or anything else to get that 7-8 hours. However if I start going on youtube for 30 minutes to an hour, listening to music, and changing from one site to the next every minute or less I can get between 4.5-5.5 hours

I actually almost never browse or use my Win partition when I'm in OS X. The load is just there when the network card is doing something, and even if NTFS is not related at all. When networking is disabled there is no load. Very strange issue. I'll give paragon a try then.

Well I'm running a 2012 rMBP which has had excellent 7+ hours battery life.

After updating, eventually, to 10.8.2 and the recent MBP/Air update (graphics drivers?) I am now down to less than 3 HOURS !!

No other environmental factors have changed, I'm not doing anything differently. Working (text editor) in the 20 minute taxi to the airport this now it has consumed 15% of the 100% after overnight charge.

People claiming "well I've not seen this", "I've never heard of this" or "stop watching the percentages and time the actual battery life" need to pull their neck in. This is a very real issue for a lot of people, just becuase it doesnt currently affect you doesnt give you the right to troll other people.

Yes, this "update" has, for me, CREATED a battery life issue which I didn't have before.

I really hope that 10.8.3 does something to change this, its obviously software/firmware related.
