Any battery life reports for new rMBP yet?

[theKitch]

My 15 is reporting Capacity of 8849, Design 8440.

I would say if I REALLY stretched I could do 11-12 hours with wifi and very light browsing.

My normal workday workload looks like I can get 8-9 hours (lots of browser, terminal, my work email app, occasional VirtualBox use)

Heavy workloads could kill things in short order, 4-6 hours.

Just curious about how your battery life is doing in regular daily tasks, even though it seems like it's only been a day. I'm still waiting on my 13" rMBP, so I can't test it myself. (also, nice to see you outside of the Waiting for Haswell thread )

It seems to drop quicker than I expect, but I use Chrome. Wonder why that is since the 13" doesn't have the 750.

I have the mid-level 13". No 750M here. Chrome's just being its power hungry self. It's doing the same thing with my MBA.

If the indicator is to be believed, my 13" should last for about 11 hours total. I have had it on for 5 or 6 hours so far (didn't time how long it slept for while I was in meetings unfortunately, but I've had it on for 7 and it slept for 1-2) and i'm still at 55%, showing 5:49 remaining. So that's 10:49-11:49, that area. Wifi on, bluetooth off, screen 75%, keyboard backlight off. Not bad! Especially since my early 2008 white Macbook that it replaced was getting about 3 hours before the battery completely failed 9 months ago.

Under what conditions are people running these tests.

On my 15" 2.0GHz, 8GB Ram, 256GB SSD, Iris Pro, at 100% brightness for both screen and keyboard, wifi on, bluetooth off, I am currently at 84% and its saying I have 6:29 left.

Does turning the brightness down really impact a lot?

Also, coconutBattery says my current capacity is 8732 mAh and design capacity is 8440 mAh, however this value has gone down a bit since yesterday. Coconut also says that I have 80%. Is it the most accurate battery app?

Brightness has a pretty large impact. tune it down to 50% and it'll go up by a few hours.

I've turned it down to a comfortable brightness which is about 45%, turned the backlight keyboard off, turned Flash off on Safari, and at 85% I am quoted 9:42!

This is much better than I would have imagined on the 15"!

The current capacity has now jumped to 8773! I'm a little confused.

Hmm, I use Firefox as my daily web browser, so I'll have to see how that compares. What I've noticed in the past is Chrome tends to do better in memory usage, but worse in battery while FF is the opposite of that. I would probably get way better battery times if I switched to Safari full time.

Does anybody know how many years can a 13'' rMBP battery (i5 2.6GHz, 256GB PCIe, 16GB RAM) last?

(Under normal daily use, temp. conditions and proper charging)

Besides, can a 13'' rMBP battery be exhausted earlier than 3 years? In this case, is it covered under the APPLE CARE 3-year extended warranty?

 

[NewbieCanada]

That is super-encouraging because Apple only rated the 15" at 8 hours. If the 13" performs as well, we could expect maybe 10.5 hours on it.

That's good enough for me, and would seal the deal on the 13" rMBP.

8 hours is about what the 2012 model gets under Mavericks, so it makes sense the Haswell would get over 9

On my 2013 13" base rMBP, I am pacing about 7 hours in actual usage while browsing, some office apps (147 minutes, 35.1% used).
