Macbook Pro Retina battery problem?

I know but today is Sunday everything if closed.

I'll do it tomorrow.

Just check if there is anyone with the same problem....

Thank you p

I think the one thing that people may be overlooking here is which CPU you have in your configuration. I had this with my Vaio Z a few years ago - 7 hours battery life is given for the macbook pro retina. But it doesnt say which CPU is being used - with the Z, the higher CPU meant more power consumption and lower battery life.

So it would be interesting to know which CPU you have. I have the 2.7ghz i7 quad core which is going to be hardest on the battery. I dont really use mine off the mains, but unplugging shows about 4.5 hours - thats going to go up with tinkering, but Im not expecting 7 hours on this model. If it was the 2.3ghz, well theres a difference there that youre going to notice and I would expect 7 hours fur sure.

2 hours sounds too low and needs investigating with Apple.

Hey there, I don't relieve what you are saying is entirely true.

I have the 2.3ghz 16gb.. And to be honest I get between 7-10 hours constant use between mail, word, excel, wifi, 60% brightness, and max res enabled. This is also with 3 spaces enabled and 4 safari windows open all the time.

I don't think a bump of 0.3ghz is going to affect battery life unfortunately

Its a hypothesis - given there isnt much to explain the difference of battery time without knowing the model differences or if firmware is an issue. Or knowing exactly that the 7 hours applies to all configurations.

Previously with my vaio Z the higher processor came with a different cooling system and different make up, so although the bump didnt appear great, it did have quite an impact on the battery life. At the time this was pretty well documented - of course Apple is a different co, but it might explain some of the differencial.

I had the Sony Vaio Z. I wanted it to work out but it went back after it failed dismally to impress me. It replaced an 2008 MBP. It was a clean install if windows, with office and adobe on it. Nothing else. Battery was bordering pathetic. And the quality felt a bit EeePc after getting over the Carbon style body. My one benchmarked on 3dmark06 at 2100.. Which was pathetic. I know it's not what everything was about, but I paid $4k for that, most I've ever spent on a laptop and to be honest was as exciting to own as an old Acer I had.

Apple is one of the few companies that deliver battery life they have promised. If yours is not delivering something is wrong. It's got nothing to do with the extra ram or 0.1 or 0.3 extra ghz.

It should be 7 hours connected to wifi doing some safari. Minimum.

Mine does about 7-10 doing a lot more.

I'm not including gaming with it. UTS normal stuff I mentioned in the above post.

If your getting less than 6 return it no questions.

Number one thing I do with all my iPhones and MacBooks is run them dead then fully charge.. Do this a couple of times a month and you'll see a massive difference.

Ruin batteries?? Definitely not. I never have. My iphone 4 was great, 4s, 5, and all my iPads and MacBooks.

This to me is undisputed.

My problem is not a duration problem. After updating the mountain lion to 10.8.2 my RMBP didn't recognize anymore the charger.

Wow Wisdom Tooth, You put your heart and soul into that one. I'll check it out.

Apple now says running the current -generation notebook battery down low is not necessary initially, and not helpful for battery life in the long run.

They now suggest you simply USE the battery once a month to keep the electrons moving about, and they suggest running it down really low will reduce battery life.

Batteries - Notebooks

Dont worry about what Apple says, if you want the best life your battery can have, let your phone/macbook die. Then fully charge it, uninterrupted.

Just trust me.

I like to give experience more than to Hypothesize, and help everyone get real experience.

Now your trying to be clever.

That was my experience / learning applied to perhaps explaining part of the problem. Sharing, discussing and helping, that's what these forums are for.

Checked my set up more thoroughly, rebooting and resetting applications and I'm getting over 7 hours.

In sharp contrast to your contributions, i got some good info from another member on the battery differences on he higher CPUs. disregard Sony.

Firstly I'm not trying to be clever. I think you mentioned something passive about me putting it all into my last comment, which was there for your benefit only.

If you have difficulty dealing with a no ******** approach to problem solving. I'm sorry for you. I do t get weighed down by the inefficiencies of communication, or another persons banter. It is what it is. Keep hypothesizing, an ill enjoy my long battery.

If I needed to sound smart, I wouldn't do it helping someone in a battery forum on the apple website.

Hope you get good battery life.

Thanks.

No, you were trying to be clever. Undisputed.

Your a whiny person. Just stop now before you embarrass yourself any further.

Since your last few posts have been to have a go about me sharing my experience, you sound like you're the one that has something to prove.

Suggest you keep on topic eh. Wisdom Tooth.
