Most recent beta.. battery?

[vdawgs22]

Has anyone else noticed a SIGNIFICANT decrease in battery life for the macbook since the most recent beta (i use a 2013 macbook air). I have been using my macbook for a 9 hour office day with no issues of running out of battery. Now after about an hour of usage I'm losing about 30%.

Not me.. every Apple update seems to affect battery life, sometimes positive, otherwise negative. I feel that Yosemite increased my battery life so far but thats just my luck I suppose.

preview 1-7 for Yosemite didn;t negatively affect me.. this one I'm not sure what is going on but now from 9-12 I'm down to 20% on my air.. i should be around 60% under normal circumstances.....i hope the battery didn't **** the bed all at once

I have a CMBP 15'' 2012 running beta 3 and my battery has about 96% of original charge and I still get about 7-8 hours with light to medium use. Watched three movies on netflix last night (~6hrs streaming time) and still had ~40% battery life left (started at 100% with moderate screen brightness)

It seems my laptop is in the same boat. Also appears that Power nap may be enabled on battery for some reason?

No increase or decrease here! Still an average of 3 hours with a maximum of 4 hours and a minimum of about 2,5 hours. MacBook late 2009, with a year old replacement battery and 676 cycles.

Mine is just as good or maybe even slightly better than Mavericks. Check your activity monitor, maybe a daemon or something got out of hand somewhere.

solution to extend battery backup

just check activity monittor,if it shows 100 % cpu usage by calendar application,or nearby figures,its the culprit.Just select it and force stop it.You will have enough battery backup

Macbook Pro 2014 and my battery life is terrible since updating to Beta 3. Lucky to get 5 hours out of it now.

First post and same problem here, MacBook Pro 2014. Can I just re-download mavericks and reinstall? Battery is no where close to what I was able to get while on the Mavericks OS

Anyone notice any changes in Beta 4 yet?

Safari is killing my battery. Energy impact during use is around 20-40, usually on the higher end of that range. Clean install GM1 on 2013 MBA. Projected battery life at this rate of 4 hours, compared to my normal projected battery life of 12-13 on Mavericks.

This has been true for every single DP, half of them clean installs.

Man, that's terrible. They'd better have this fixed by the time the actual update goes public, or they're going to have a lot of pissed of MBA users. The battery life is 99.9% the reason I chose the MBA over the MBP.

I have a feeling I'm in the minority, but yes I do hope that the issue is fixed

I'm streaming pandora in safari and see 6%, no apps using significant energy.

Yup, battery life went way down for me as well. Was PB 3 and got around 11/12 hours and with PB 4, it is now about 5 hours.

Make sure you guys make a Feedback right now....


Edit: Powered up my battery again to 100% and now it shows I have about 11 hours of battery life instead of about 5 hours. Than a couple of minutes later it went down to about 10 1/2 hours. Go figure

Edit: Here are three shots of battery power being reduced within just a few minutes of each other..

Frustrating! Particularly when they touted during the keynote that changes in Safari would reduce power consumption.

Macbook Air mid 2013 - battery life is bad - not eve close to mavericks.

I've been running actual battery tests and I'm getting an average of 5-6 hours browsing and normal writing/reading use— no video or audio. make sure to submit the feedback people!
