WOW! So I unplugged my new 13" rMBP to give it a fresh cycle and says 18hrs 44mins remaining. I know that's idling but my old 2009 MBP was down to 2.5-3hrs idling on a full charge.

What kind of battery life with actual usage have you been experiencing?

I've seen my 15'' haswell max model hit 19h 45 min with 4 ticks brightness, wifi off, and microsoft word open.

If I am just word processing, low brightness, wifi off - It lasts a solid 16 hours
 
I got my 13" thursday, and it had about 80% battery. I used it for web and word processing for about 8 hours, and it was still over 20%. Not overly scientific, but I was impressed.

I haven't run it down that far since.
 
Does anybody know which is the max. battery life of 13'' retina MacBook pro?

I consider normal use, under normal weather conditions (mostly) and normal charging cycles without staying on AC power for a long time.

Any estimate? :rolleyes:
 
Well after using it for a full charge I can say I got about 9-9:30 of my normal web browsing usage on my 15". It all depends on how you use it of course, if you use it very light on low brightness you can probably squeeze 10+ hours out of it. On medium to heavy use you should get around the 8 hour quoted number. Granted these are just my estimates after using it just a couple days. For a quad core 15" laptop with a screen of this resolution it seems pretty great though.

Thank you.

Also, do you know battery life limit? 3-4 years or less?
Does APPLE CARE extended warranty cover battery replacement under normal daily use, correct charging and average temp. conditions?
