    Had one leave a message today, but we we didn't connect live. Will try again tomorrow.

     

    Rewiewing the posts again and on account of my own experiences, I've noticed a commonality; that the problem seems most apparent when under 'basic' use ie; running Safari, Mail, iTunes, Firefox, etc. While these are considered minimal battery taxing tasks, Activity Monitor seems to say otherwise. Just a thought; Open up Activity Monitor, and arrange by %CPU usage. Now open Safari and scroll up and down for a few seconds Does Safari's web content jump to the top of the list at >50% on your machines too? I'm not an expert, and I'm not sure if this is normal pre-Lion, but 50% sounds high to me. Similar percentages can be found when doing this in Mail, Finder, etc. If this is an extreme percentage for scrolling, could this be part of the cause for the extremely low battery life? As I posted eariler, on a full charge sitting at idle I can acheive Snow Leopard's estimates (around 6hrs), but as soon as I open up Safari and start browsing, I get an instant drop to around 3:30. I realize that battery life will drop faster while the computer is in use, but I never saw such a drastic change in under SL.

    MacBook 13" mid-2009, suffering battery loss also since Lion AND iCloud.

     

    It's encouraging to know that Apple is contacting people in this thread.

     

    But I haven't read all the 80+ pages to check if someone had mentioned if Wi-Fi, iCloud and internet have something to do with this also. In my case, I've noticed my battery estimated time drops dramatically after connecting to Wi-Fi (about 5 hours to 1:30!). I guess many of you guys have Wi-Fi enabled all the time, but I don't, so I could noticed this change.

     

    As a iCloud user, some recent syncing issues make me think if a sync bug could be related too. I don't know if it's related or not, I've sent feedback about that to Apple. The more angles they check, the closest we could be to a solved issue.

    Just for the record, same issues here... 2011 15" Macbook Pro...

     

    I can't ever remember my fan not being on...........

     

    Before I got my first two replaced I do remember them being a lot quieter.... I'm always getting a bit of a subtle drone these days.

    Admittedly I have been a fool and one of the early adopters for LION(July23rd). Have read through almost all posts and have tried all solutions suggested other than going for clean install or downright downgrading to SL.Pre so called upgrade running Safari+iTune+Mail on wifi would give me a solid 8+ hrs of life but nowadays can barely get 4hrs(mine is a early 2011 MBP with i7 2.2 GHz, 8 GB DDR3 and 1 GB ATI GPU) against the promised 7 hrs. Have patiently waited for updates and have both patches installed but am at the same horrible place as all others in this thread with the same heating, fan revving up and 50% battery life problems . But surprisingly what I can see is that no one is talking about one issue - the increase in bootup and power down times. Pre-upgarde it would take 15 seconds to bootup and about 5 seconds to shutdown which with roaring LION has gone to about 45 seconds and 20 seconds respectively. So wanted to check with others on this forum if someone else is observing the same? I have tried the usual stuff like clearing startup programs etc but did not help. Any ideas!!!

  • Video Guy Level 1 Level 1 (40 points)

    Yeah, I've noticed the slower startup, shutdown as well. I've upgraded only 2 weeks ago, and was hoping it would eventully get faster, but it sounds like not. 

  • milwaukee_bronze Level 1 Level 1 (0 points)

    I also got a call from a Senior Tech. last night.  They pulled 2 sets of logs which I duly mailed over.

     

    I assumed this was triggerd from my ticket to support but the tech told me he was reaching out based on this thread. (Sound familiar?)

     

    It sounds like maybe we finally hit critial mass. Let's hope all our logs steer them to a clear solution.

    Chiming in again with a late 06 MBP 17" with 2.33 C2D. If an engineer is listening I'd like to add something I mentioned previously in this post: Firewire adds to the heat/volt/power issue. The moment I plug in Firewire, either an external D/A converter or HDDs, the voltage jumps from 0.88 to 1.18. The heat then follows, the fans kick up full blast, etc. So there seems to be a link to Firewire, at least in terms of excessive voltage. My initial suspicion was an problem with the powermanagement .kext. Just my 2 cents.

     

    I can also confirm CPU spikes when scrolling, and much longer boot and shutdown times. And oh yeah, significantly reduced battery life. My model never got 7+ hours, but I have gone from 3.5 to 4 hours down to less than 2 hours.

    Any extra electrical load, like spinning the motors in a hard drive will cause more heat, more work=more heat.

     

    Now, where are you getting the 0.88v & 1.18v readings from?

  • rgnabisco Level 1 Level 1 (0 points)

    the readings are coming off istat menu. looking at Volts to the CPU.

     

    I understand that a spinning HDD might cause/require additional voltage to operate, and at the end of the day simply unplugging solves the problem. but let me just say this: I get the same voltage spike when I plug in a D/A converter that has no moving parts. Also, all of my firewire devices have their own dedicated power supplies, therefore they shouldn't need additional power from the computer to functions. Also, I'm talking about voltage to the CPU....why should that be affected by plugging in a device and letting it sit idle? Finally, with the exact same setup under SL, this voltage spike does not happen. I'm not, I repeat, NOT a computer engineer, but with hardware staying constant, that tells me it's a software issue.

  • Csound1 Level 8 Level 8 (44,135 points)

    All electrical devices draw power from the USB bus, spinning motors tend to draw more but it does not matter what you plug in, if it requires electricity to operate then the Mac has to supply it (unless it has it's own psu, in which case power required from the Mac is lessened)

     

    CPU voltage varies with CPU load, unless you are corelating this with CPU load factors it means nothing other than a process needs CPU attention, probably connected with whatever you plugged in.

    Adding to the list of affected users with my July 2011 MacBook Air 11" which came with Lion pre-loaded, now at 10.7.2 . Until a few days ago, battery time was 6 - 7 hrs. The only thing that dropped that time noticeably was watching video. I mainly have Chrome open with 5 - 10 tabs, Evernote and some light Office Word or Excel use. Even playing Angry Birds didn't cause unusual, major draining of the battery.

     

    Now the Air battery loses about 5% every 10 minutes even when sitting idle (nothing open at all) and lowered screen brightness. The only thing that has changed is that I bought an iPhone 4S and set up iCloud on it and on the Air. I also created a Google Apps account for my domain and on the Air, I keep the email for it open in Chrome. Tried turning off iCloud on the Air, tried some of the suggestions in this thread and from other threads and articles. Using Activity Monitor, I've tried a few other tweaks like quitting processes (Evernote Helper, my printer's Network Scanner). Nothing has helped so far.

     

    On the iPhone, the Google Apps Gmail is set up using Exchange. Since the 5.01 update about 4 days ago, and turning off Exchange and Gmail calendar/contact sync the iPhone battery life is finally stabilized with 67% remaining today after 12 hrs of email and a few long-ish calls. As soon as the iPhone stabilized, the Air started the crazy battery draining.

     

    Sure hope they fix this soon.

    Same problem here too. I updated to Lion last night and my battery life was cut more than half. I normally get about 5 hours with safari, mail, and word open and using all at the same time. I now get 2 hours and it drops to one hour VERY FAST! I took it in to Apple Store today and they blame an "error in the downloading process." They say that if the Internet connection is interrupted then the software can become corrupted. They wanted me to buy an external  hard drive, back up, and then let them reinstall lion. That was basically my only option (which i did not take). They also acted like no one else had come in reporting this problem.......

    I hope they release an update for this SOON!

    Who ever told you that is full of $#!~ and have no respect for the customer!

     

    If you can, go back to SL10.6.7 (make sure not to update to 10.6.8) and battery life will be as used to be or continue with Lion (really nice) and hope that Apple will come up with the fix soon

  • Sir Allan Level 1 Level 1 (0 points)

    Still nothing...

     

    I am losing my hope.

  • monkeyandy Level 1 Level 1 (0 points)

    Yep - me 2! Great batt life on Macbook Pro Mid 2009 until Lion upgrade, was getting nearly a full day off my battery but now about 3.5 hours. Bummer!
