Hi,

I've just acquired a MBPr directly from the Apple store 2 days ago but I've noticed the battery was draining pretty fast. I was wondering if this was normal in the first few usage of the computer. Here are some examples

From 100% to 90% in just over 30 minutes
From 85% to 80% in under 10 minutes
From 80% to 71% in 9 hours in sleep mode

All of that with only chrome opened with two tabs, except from sleep mode I had exited all applications. I've now uninstalled chrome and went back to safari as I heard chrome is a killer.

The only other app that could be causing a problem is my VPN, PrivateInternetAccess, which I also quit to see if it was source of the problem.

Here are two screen shots of the activity monitor as of yesterday and a few minutes ago

As of right now, it's 10:03 and 62% with 9:37 remaining.

p.s. I'm concerned because I have very bad luck with laptop. My first Yoga had a defective battery (wouldn't hold 2-3 hours), had to send back, no more in stock so I got a Samsung Series 9 which I received with a broken keyboard, had to send back to get a replacement.

I'm also very concerned because I leave out of the country Monday for 6 months, so I really hope nothing is wrong!

It's now 10:06 with 61% and 9:07 remaining.
 
Just use the computer as you would any computer.

Turn the percentage indicator off, it's a rough estimate at best.

Your battery life will fluctuate depending in your usage.
 
It must have been Chrome or my VPN, now lost 10% in a hour with Safari, which is good!

*phew

Definitely without a doubt Chrome. Is very well known battery eater (And RAM eater)

Try to stick to Safari on battery and only use Chrome if you really need to.

Google are aware and have said they're going to work on reducing it (Both RAM usage and battery usage).
 
I stopped using Chrome, and all seems good now. The only thing I'm worry about is the almost 10% gone in 9 hours of sleep mode.

That doesn't normal to me

It's actually quite normal.

You should it see go down roughly 1% per hour. Yours is within spec.
 
Sounds good, thanks. Anyway I usually turn off the computer if I'm not using it
 
A new machine would also likely have been Spotlight indexing, that will also use additional cycles and battery until completed...
 
That also makes sens. The more I use it, the better it gets. It only dropped 1% over the past 15 minutes, which is awesome.

Also didn't loose any % while on sleep mode for a few hours earlier. I'm glad the battery is good finally :D

Thank for you help everyone!
