I just can't get the expected battery life

[nalbagli]

Thanks for all the inputs, I don't have any extension installed on Safari, and I've been constantly checking the Activity Monitor and Safari is usually having a High Energy Impact that moves from around 90 to 120. This is a screenshot of my activity monitor with only Safari open and non with flash content only forums twitter and stuff like that.
About Console and Disk activity, sorry for the ignorance but I don't know how to do that could anyone guide me. This has been a pretty frustrating experience with battery, especially because I love this laptop

Thanks

I have just realized usually something called Safari Networking is what consumes the most energy...does anybody know a fix for this?

1- Uninstall Dropbox or update it to the latest version, I have read others have had issue with DB eating CPU cycles.

2- Create a new user account with the same privileges and try the same web sites, this will help to "prove up" if the issue is solely related to the web or your accounts set up.

Thanks! I'll try that and tell you how it goes.

Other thing I've noticed is when browsing a Facebook tab for example with a video playing, cpu usage is close to 80, is that normal?

Cant say as I don't use Facebook, equally 80 on Activity Monitor is less than 25%, (2 CPU Cores + 2 Virtual Cores). For instance if you encoded a MKV video to MP4 with Handbrake the CPU usage would be close to 400. it`s likely the OS has to convert the video "on the fly" I have see the same on video with some streams,. Sometimes reloading the page helps, or you have to just live with it.

It may be simply the drain is systemic to your usage; so in that case look at my post (#2) earlier in the thread and try turning somethings off, as small savings add up. If this is the case the relationship regardless of Notebook will be linear i.e. you will repeatedly have less run time than others with the same system. In the case of the rMB the battery capacity is small to start off with, resultantly it`s easier to negatively impact. I see 6-10 hours on my own rMB 1.2, clearly the runtime is highly dependant on the usage. If you want more running time then you will likely have to compromise as your usage "I think" is driving the issue, I don't think there is a specific issue with your Mac given what has been described. Hopefully this helps, or at least elaborates some.

Any errant application would stand out in the Activity Monitor (CPU and or Energy) as you don't observe this it has to be the sum of everything, or possibly you have a persistent application that the OS is unable to "freeze" when not in use, equally this should also be apparent in Activity Monitor (Energy Impact).

I'm stealing this from another thread, but someone said they noted they had pretty poor battery life on a MBA and eventually figured out that it was due to too many "active" notifications and when they curated that some, it got a lot better. Not sure if it's the issue but just putting it out there.

I tried some of the things and know I don't see Safari Networking draining that much energy, neither is safari, with youtube playing it's around 40-50, strange thing is now my battery estimate is even worse! around 4 hours with 87% of battery and draining fast. I can't make no sense for this
