I would like to know whether Maverick will let you have longer battery usage on any other MBP or rMBP ? Anyone has this experience please share your thought.

I've used my MBP 15" late 2011 on Maverick for couple of days.. Below is my screenshot on battery mode showing 8hrs for 96% .. I'm not sure how accurate is this but I only running few tab on Safari and Messages ..I don't think it can last 8hrs...maybe only on surfing text? I think slightly 10% battery life increased after upgrade to Maverick

I currently have an issue when my MBP is in sleep mode. I close the lid before sleeping. When I open it next day, the battery has almost no power anymore.

My second dev rMBP had that problem too, then I removed a lot of unnecessary programs from OS X and repaired permissions with disk utility, after reboot sleep worked as before.

Also remember to disable Power Nap.

I had it enabled in my battery profile and noticed slight increase of battery usage when in sleep mode.

Of course it could be my head as I have not heard others have same problem, yet.

But, if there is some problem in it, I expect it to be fixed in following months, thus I will try to enable it back after 3-4 updates.

Why?

Below is my screenshot on battery mode showing 8hrs for 96% ..Why do so many people rely on what the battery stats say? It's just a guess. It changes constantly depending on what you are doing. I suppose if you just sit and stare at that "8 hour" banner while doing nothing else, you just might get close.

The only way to determine how much time you get out of charge is to time it yourself. No two people will get the exact same usage time.

I unfortunately don't have this option under System Preferences > Energy Saver.Power Nap is only for Retina MacBook Pro, and Macbook Air since 2010 (http://support.apple.com/kb/ht5394). If you have a conventional MBP, you can't use Power Nap, so that probably explains why there's no option for it in System Preferences.

Isn't that expected behaviour? Power nap is doing stuff at intervals whilst your Mac is "sleeping". This has to consume more power whilst sleeping than if it was not enabled.

This feature was introduced in Mountain Lion so you should be able to find out if what you are seeing is expected.

Hyuga

My apologies, I should have given more detailed message.

I had it enabled before in 10.8 and noticed after upgrading to 10.9 dp1 that it consumes more battery, or so I at least think.

Has anyone with a 2013 MBA tried it yet? The battery life on those is already ridiculously good, I'm wondering how much more it will improve with Mavericks. :D

Weird. Clean install onto a new partition on my rMBP cut my battery life right down; from 7-8+ hours on a full charge to only 4 or so. I found my battery life to be really excellent under Mountain Lion but for some reason Mavericks is sucking the machine dry. Pretty stumped given that it's from a clean install...

What did you guys do in order to achieve these battery lives? Anything special?

Not anything big, I noticed that it runs bit smoother when you switch between spaces, and of course scrolling is a lot better in safari now, especially if you don't use native scaling.

I was aggressively watching energy tab in activity monitor first few days, and noticed that Safari overall uses most battery in my system. It seemed that safari had trouble with some web pages and they consumed a lot of cpu in the background. Also afterwards I put ClickToFlash back to my safari.

Just watch activity monitor and try to find what is using all your battery.

For people who are interested, see attachment.

Battery lasted successfully (2.6GHz rMBP) flight from USA to Europe, wlan and bt off, brightness was usually around 10-20%. Computer was sleeping during inflight meal.

No surfing with Safari, twice watched short 1080p movies with VLC and listened music from iTunes. Rest of the time it was Word and Excel.

I've noticed a 15-20% gain in battery life with my 2011 MBP 15", too.

Not scientifically measured, but I've managed to get 6+ hours on battery browsing with a fairly flash-heavy website (cisco netacad.com)

The GPU switching is much more intelligent and you can also find out which app is causing the discrete GPU to kick on now too.

My battery life improvement was on DP1. Its possible you have a driver or something that doesn't work with the new kernel interrupt coalescing or something and that impacted battery life.

Haven't tested DP2 on battery yet, will do so in the next few days (just installed a few hours ago).

But DP1 for me was great.

i5/i7 both use similar power when 99.9% idle, as most machines are most of the time.

it may chew more when doing more, it may race to sleep faster.

Power consumption between i5/i7 = meh.

I get about 5-5.5 hours with normal use (Web Browsing, watching videos, Microsoft, office, iTunes, etc.), so if this could bump it up to 6, 6.5 that would be sweet.

Curious, did you upgrade or clean install?

First I did a clean install on a new partition and after confirming that all my necessary apps are working fine I deleted the partition and upgraded 10.8.4.

Unfortunately it's not so great, I feel it's less responsive than Mountain Lion and sometimes it will lag so much I have to do a hard reboot, since I can't even force quit anything.
It's fine though, it's beta. When Mavericks is released I will do clean install - I think I have been upgrading since 10.6 Snow Leopard, so it's time for some fresh start

Davmeister
Jul 3, 2013, 03:14 PM
I've noticed that consistently now finder is using about 50-60% CPU, even in the background. By force quitting it, and leaving the application in the background from that moment on, it remains at 7-8%. Opening a window or switching to it shoots it back up to 50-60.

Something surely wrong here on my system.

I shall try this. Cheers.

Sorry, one more thing. I also have this weird flickering of the airport menu when rejoining or waking from sleep.

airportd in activity monitor uses about 600% cpu during this period. Normally settles down after a while. Have mentioned in dev forums.

Hi everyone.

I recently installed Mavericks DP5 to test it out, and to see how it behaves regarding battery life, my most important concern.

I was using 10.8.4 before, with a lot of updates, from 10.6.3 from my old MBP 15" 2010, to my 6 months old rMBP.

First of all, I created a dual boot installation for Mavericks, on the rMBP. I don't notice much speed increase with my old installation.

There is less lag while using the launcher or Mission Control as there is with 10.8.4 with the Retina, that's for sure. But the apps launch as quick as before, the start up is a bit slower (thus I have lots more soft installed on ML).

I used Google Chrome Canary on ML, because Safari was horrible with lots of lags. I tried the Nighty webkit, but it did not improve much.
I reinstalled Google Chrome Canary on Mavericks, and the experience was the same as on ML, quite nice browsing experience, not much lag, quick, reliable...

But I started using Safari 7 on Mavericks. And now, the surfing experience is really great I think, better than Canary, everything is smooth, I don't have much issue, so it became my main browser on Mavericks.

Let's talk about battery life.

I never complained with my rMBP about battery life with ML, it was always btw 5-7h depending on the load, the backlight intensity.
Always unsung the HD4000 on battery, with GFX Cardstatus.

This is only the 2nd time I am on battery under Mavericks, but for the moment, I notice some improvement with battery life.

This is now 6h30 that I'm on battery.
Continuous use and wifi always on, maybe 10 min of standby time.
30 minutes using windows 8 under Parallels 8
30 min streaming videos with flash on
Safari always on with at least 5 tabs, and up to 12.
iTunes turned on roughly for 3 hours
And iStat Menus indicates still 3h20 remaining.
Screen set between 25 to 60% of backlight.

I usually plug the Mac when the gauge indicates less than 15% remaining, I presume that I'll get something like 8h30 of real battery life, which is quite nice considering the power, the screen...

I'll need to do the same test under ML to compare the true gain in battery life., but Mavericks seems to be well born.

What rMBP did you use? Did you see an increase in graphics memory?

Vinz-uk
Aug 15, 2013, 12:27 PM
My rMBP is the based model: 2,3GHz - 256Go - 8Go of Ram.

Yes, apparently on the HD4000, it seems that before there was 512Mo of Ram on ML, and now on Mavericks, the "about my Mac" displays 1024Mo of Ram for the HD4000.
Maybe the HD4000 can use more Ram on the installed 8Go of Ram.

Hi I recently did a clean install of Mavericks GM on a macbook air 2013 (the last model): my battery life is expected to be of 5 hours with 100% ! I realized that Finder is using nearly 60% of the processor although I did nothing special and that is surely the cause of the draining of the battery. Curiously after some minutes Finder's activity is normal but it can reach another 60% a few minutes later. Does anyone has this problem with GM. Thanks for any help.

These screenshots people are posting don't really mean anything. They just show an estimate for the battery, that was calculated at the time the screenshot was taken, by considering the current load of the computer. I had once 12,5 hours left, according to the battery meter. Of course I didn't achieve 12,5 hours..
Having said that, on my rMBP with heavy usage of Safari and having 10 apps open at the same time, I get 5-6 hours. This is a bit better than with Mountain Lion.

Don't forget that Spotlight might be indexing your drive, so battery life will decrease (temporarily).
Mavericks offers vastly improved battery life.

Battery life has become worse in 10.9. It was REALLY great in 10.8. Battery drains really fast now when using Safari. I did a clean install and I just reset the SMC. A little bummed out about this because otherwise Mavericks is great and all my programs are working fine.

However, my computer seems to be running cooler these days, compared to ML.

Looks like i am the only one getting worse battery on Mavericks than mountain lion. i am getting about 4 hours compared to around 7 with ML.

Nope! Me too. I went from 13 hrs with Firefox running on 2013 MBA to barely 8 at 100% charged. down to 6 hours at 85%. Nothing changed but the OS install while on AC power

What can I do? This SUCKS

It's most likely an app that has not been updated for mavericks yet. This post was from back around July when they first announced it. I found out the problem was from an app called cinch that I had running. Once I stopped using that app my battery life was good

Since updating I am only getting around 3 hours per battery charge on just surfing alone where I used to get at the minimum 8 hours depending on what I was doing and I have just noticed that it has only taken 45 minutes for the battery to recharge to 50% so something is obviously not right here although I don't mind the quick charge haha.

Just fully charged (after about an hour) and looked and it says that I only have just over four hours remaining.

Also looking at the battery usage in Activity monitor it says that my time on battery is 18 minutes and the charge has already dropped down to 93% within that time.

Surley this isn't right and it most certainly wasn't like this prior to the upgrade!?!

I have a July 2012 MBP non-Retina 2.6 GHz, upgraded from 8 to 16Gb of memory. When I went from 10.7 to 10.8, I went from 8 hours to 6 hours of battery life. I have tried all kind of fixes, and nothing helped. Going from 10.8 to 10.9 has brought me back to 8 hours.

Weird. Clean install onto a new partition on my rMBP cut my battery life right down; from 7-8+ hours on a full charge to only 4 or so. I found my battery life to be really excellent under Mountain Lion but for some reason Mavericks is sucking the machine dry. Pretty stumped given that it's from a clean install...

What did you guys do in order to achieve these battery lives? Anything special?

Same here except i upgraded from Mountain Lion. The battery life on my MBP 2009 is now less than 2 hrs on Mavericks when i use to get around 3.5-4 hrs of battery on ML

I did repair disk permission in disk utility as when i verified the disk, there were many issues. Along with that i recommend you to reset the SMC. Worked for me and m back to 3hrs+ battery life. Just saw the battery health and its down to 65%. Still very impressed that i could see 3 hrs of video playback at that health. Loving Mavericks.:D:D:D

Nope, you're not the only one. I have a MacBook Air from 2012 and I used to be able to keep my laptop in my backpack on sleep mode the whole day and when I got home it'd still be at 95%. Now when I get home, after not using it at all the whole day and having it on sleep mode, it'll have 45% left.. I find this really weird and frustrating.

I was getting 8hrs+ with ML usually running Safari, Mail, iTunes, Messages and maybe a few other bits and bobs.

I'm getting 5hrs at best under the same conditions with Mavericks after a clean install on an early-2013 rMBP (my battery health is still 100%!).

Any suggestions or clues or just wait it out 'til 10.9.1?

I have a mid 2010 2.4GHz Core 2 Duo Macbook and since installing Mavericks my battery life has significantly decreased. Many other users on the Apple forums are experiencing the same issue. Apple has done nothing to address this problem. Apparently they think nothing is wrong?
I have submitted a couple bug reports about it. I have tried resetting the SMC and completely erasing the hard drive and re-installing Mavericks. Nothing has worked. I reinstalled Mountain Lion and my battery life shot right back up to the way it used to be.
