Hey guys.

  1. Why isn’t the Safari bug fix which was the cause of the inconsistent battery life in MBP 16 not addressed in the updates list? (pic attached)
  2. I’ve done battery life test in my 2016 MBP in 10.12.2 for a continuous moderate-heavy web browsing session throughout which yielded unacceptable battery life for me. I don’t want to do the same thing again, it’s tiring. Is there something like an automated web browser test which repeatedly loads uncached websites to get a new estimate of the battery with the update similar to something what ConusmerReports did as in the attached pic?
  3. Is this update gonna give any improvement for my classy 2015 rMBP which is already on 10.12.2 with Safari?

According to this:

http://www.macworld.com/article/3159737/macs/macos-sierra-10123-update-fixes-the-safari-bug-that-affected-macbook-pro-battery-life.html

it does include the fix for that Safari bug, which should help with battery life on the MacBook Pro. Also, note on the bottom of that link that it states the update includes security fixes. Here are the details of them:

https://support.apple.com/en-us/HT207483

And, there is another thread about battery life which you might want to look at:

https://www.mac-help.com/threads/macbook-pro-2017.223012/#post-1544774

Note that on that thread, some folks expect Apple to be more "exact" about battery life. That's not going to happen, just like MPG ratings for automobiles.

So I guess as a normal user, caching turned ON by default, there is nothing to worry about for most Apple's user base. That's why I guess they didn't mention anything about this in the change log.

Quoting from Apple's website,

The wireless web test measures battery life by wirelessly browsing 25 popular websites with display brightness set to 12 clicks from bottom or 75%.

So Apple's stupid enough to use caching for their own test loading 25 websites with 75% brightness. No wonder why I don't come close to Apple's estimated battery life even in low brightness. Isn't this pure cheating?

I use Google Chrome, so I am not affected by the "Safari bug".

As for battery life, I already stated in that other discussion forum about getting more than 9 hours watching videos with VLC (both TV series and movies). I don't have the brightness turned down on my MacBook Air.
