    I think this is a Lion issue because I'm experiencing it with the new Macbook Air i7 256GB SSD 4GB RAM. This is a HUGE issue since the Air is suppose to be portable. My battery has already decreased from a health of 100% to 96% within the two months of buying this computer. I was waiting for the 10.7.2 upgrade, but I'm not sure if it made it much better.

     

    After the 10.7.2 upgrade. Preliminary testing shows that my battery goes down to 80% after 38 mins, then 78% after 46 mins which means about 3hrs - 3.5 hrs of usage. This was starting at 6488 mAh.

     

    I've also started tracking some Coconut Battery information:

    Starting at 5490 mAh - Screen Brightness Half Way - iTunes Playing - Mail Full Screen - VPN running - Chrome Surfing - Word 2011 open in background. After 3 minutes the charge is 5433 mAh, 4 minutes after that 5328 mAh, then 4 mins after that 5267 mAh. That's 223 mAh in 11 minutes, with a total charge of 6488 mAh, which gives an estimate of 5hrs and 20 mins.

     

    So I'm not sure which is a more real number, the battery left that I have remaining or the way that Coconut Battery is going down? Currently at 5045 mAh and estimated to have 5:13 hours left, but then it jumped all of a sudden to 4:20 hours, and then jumped back to 5:18 hours.

     

    I guess we'll have to wait and see...sigh.

    I am seeing a slight improvement after the 10.7.2 update on my 2011 15 inch 2.3Ghz MBP, finally seeing 6/7 hours battery life again.

  • Poikkeus Level 4 Level 4 (2,785 points)

    rennyz,

     

    I'm glad to see that you see some improvement on your battery. This issue have begun to really interest me.

     

    How do you actually calculate the battery life? Do you rely on the prospective times on your MBP, or do you time an entire session until you get the actual time a unit is used, and subtract the sleep time? Many users begin with a 7 hour battery - but when you pay attention to actual use, it's closer to 3 or 4.

     

    Thanks for your input!

  • rennyz Level 1 Level 1 (0 points)

    I actually just refer to the battery status on the menu bar. I think if I timed it, it would actually be more than the estimated time. It also depends largely on what programs are running, screen brightness, whether I have Bluetooth or WiFi on/off, etc.. if I only have Safari open, I can get 5/6 hours. If I have WiFi and Bluetooth turned off and I'm using a program like Pages/Text Edit, I can get up to 8/9 hours.

    Now I see where people are getting these numbers from, I feel a lot better.  Extrapolating existing usage is like politicians arguing about  the economy.

     

    Does anybody have actual data on battery life under different use scenarios; document editing only, surfing only, video conferencing, games playing etc.

     

    Is there a proper benchmarking system available that everybody could use?

  • DrChandra Level 1 Level 1 (0 points)

    We are all just dummy users and there is no need for benchmarking. The only criteria is that under the same circumstances we don't get the same with Lion what we used to with SL, end of story. There are almost 100,000 hit on this forum and that should give to Apple and all visitor some indication that this is the real issue.

     

    I'll repat for all new comers:

     

    1. Battery performance if you use Lion is very poor

    2. Apple still didn't fid a fix

    3. Not officially recognized by Apple

    4. Potentially affects battery health (overall)

    5. Log tha call with Apple in case you need battery to be replaced

    6. We need a volunteer to create a Facebook page to go public about this issue

  • mpavlekovic_CRO Level 1 Level 1 (0 points)

    I have same problems like other. My Macbook Pro work 2 hours less then SL. When I back SL have again 6-7 normal operation. I'm disappointed with Lion. I hope Apple will fix this.

    I'm thinking about returning on SL again I wan't back my 6 hours on battery.

    You have no information regarding your battery life other than an estimate, if you can't be bothered to actually measure your battery life then who cares.

    If you're really new to this thread, you should also know:

     

    1) Is not true for all users

    2) Is only true if you're in a small minority

    3) Apple only "officially recognizes" issues in most cases by issuing a fix

    4) There's no evidence that battery health is affected in any way other than would have normally been the case

     

    5) I wholeheartedly agree - if you are having an issue, log a call with AppleCare about it.

     

    I still experience longer battery life in Lion than I had in Snow Leopard.

  • marysplacestudio Level 2 Level 2 (385 points)

    Small minority? Not sure how you determined that. It would appear—having followed this thread from the beginning—that it is affecting a significant number of users. Many users may not report it or even notice it if, like me, they remain plugged in most of the time, only to travel here and there for short spurts.

     

    You could add that battery performance is significantly affected by which browser you use, and of course, whatever third party software you may be running. Furthermore, there are improvements in battery power for some users who reset their SMC and, on newer laptops, use the gfxCardStatus switching software (though I personally saw little significant improvement).

     

    For the record: I bought two brand new MacBooks running Lion, and both of them were getting between 2-3 hours with basic email and web browsing. So I returned them and bought a third brand new laptop that still ran Snow Leopard. It gets about 6-7 hours basic use with the screen half-dimmed (that drops significantly when using Firefox or Chrome or any Adobe software). 

  • Rayced Level 1 Level 1 (15 points)

    @Kucharski:

    I think the small minority are those claiming a longer battery life in Lion than in SL. I mean, seriously, are you just trying to drive nuts people even more than this issue is alredy doing? Playing with two different OS versions and other uneeded applications because of the very poor battery life we're experiencing with Lion, is far, very far away from the old days of user experience Steve Jobs had in mind.

     

    Otherwise, please, tell us what have you done to get a better battery life with Lion on your laptop compared to SL.

  • William Kucharski Level 6 Level 6 (14,890 points)

    1) Installed Lion.

     

    I went from about 3.5 hours on a charge running Snow Leopard to over 4.5 hours on a charge in 10.7, up to five in 10.7.2, depending on what I'm doing, mostly web surfing over Wi-Fi.

     

    Note my use of Flash is minimal at best, and most web pages are reasonably static without all kinds of animations and video.

     

    Energy saver settings on my MacBook Pro 5,1 are set to "Better battery life" and the GPU is set for better battery life as well.

     

    I can certainly imagine there are glitches that reduce battery life for those with the newer auto-switching GPUs, but among the thousands of MBP owners I work with daily, the complaints have been minimal, usually centering around updating Flash and not leaving things that constantly access the network running in the background.

  • terifromwinchester Level 1 Level 1 (5 points)

    Rayced, After doing everything I could on the forum, to no avail.....

    I went to the Genious bar hoping to get a new battery since I am still under warranty and was told Carbonite is the culprit that is sucking up my CPU and my battery. Once I disconnected those, speed increased and battery life went up from 2 to 5-6 hours.

     

    I am glad, but not completely satisfied as under SL I could have Carbonite running and an External HD and not have the snail speed or short battery.

     

    For now, I am disabling Carbonite and external HD while I am on the computer and enabling overnight to do my backups. Not ideal, but that is what is working for me, until Apple admits there is an issue and puts out a fix for it.

     

    I am not going back to SL.

  • Rayced Level 1 Level 1 (15 points)

    Well I've done exactly the same as you, except I don't even have installed flash player! My battery life is, as for other users here, around 3-4 hours now while before was around 6-7 even with flash player installed.

    By lurking the thread it seems there's a plethora of other users here in the same situation as mine, you're the only one claiming a longer battery life after installing Lion.

     

    Lucky man, aren't you?
