Terrible MacBook battery

no thank you Mr. Obvious
everyone with the battery problem has normal cpu activity. we need some real ideas to what the culprit may be.
You're the one saying something is wrong. Apparently you'd rather continue with that assumption, rather than troubleshoot and resolve the issue.
That's not true.
yes finally - someone who agrees. I barely use anyhing just surf the web. if this is "normal" and this is apples standard then i'm not a satisfied customer. i was advertised 7 hours which ive never gotten and like ive said i would be happy with maybe 6 hours or 5 and a half but i havent gotten that either!!
brightness full or lowest doesn't matter it consumes the same much battery
If it's out of the 14 day exchange/return period he cannot return it. Also, they don't HAVE to replace the battery for free. Apple only replaces the battery if it fails their diagnostics.
I don't think this is normal. I bought a 15" cMBP last year in August, I have 67 cycles and 98% battery health (and it's been 98% for months on end now). At 50% brightness, I get over 7 hours of battery life if I'm just web browsing. Right now I'm at 86% battery and it shows 7:07 left.
I would at least take it to Apple, they can run the diagnostics for free and tell you if they can replace it for free or not. It's then up to you whether you want to do whatever they tell you they can do.

That doesn't make sense. That's simply not possible. (Regarding the brightness level).
Can you download Battery Health from the app store and tell us what the battery health is?
That's not true at all. There are many factors that impact your battery life, and screen brightness is one of the more significant ones. See the BATTERY LIFE FROM A CHARGE section of the following link for details, including tips on how to maximize your battery life.brightness full or lowest doesn't matter it consumes the same much battery
The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.
From the first post:
thank's for telling me whats true and not true? i have watched the batter for several months now and ive just dont a test and here are the screenshots - i was browsing the web and listening to my itunes playlist

I own the exact same machine you do. 2012 13" MBA with 128GB SSD and 8GB memory... identical.
Using my machine like you just described I get about 6-7 hours on battery.
I don't see anything in your Activity Monitor screenshots chewing up CPU cycles.
Something is definitely not right there and the battery dropping like that in 1.5 hours is not normal. I would take it in to Apple for troubleshooting.
You have a TON of stuff running up there. Uninstall that stuff (or better yet do a fresh install of OS X) and see what your battery life is.
But even running full-tilt your battery shoud last longer than an hour and a half. Take it to the store and have them look at it.
what do you mean i've a ton of stuff running? i have dropbox which doesn't do anything... memory clean and battery health... that's all and caffeine which doesn't take any battery. and the 19 thing is my adobe updater.
nothing there really don't know what you're talking about?
please explain a bit more?
Some programs have bugs in them and won't let your Mac fall asleep, or they increase idle CPU usage, activate your dGPU (if your Mac has one) etc.
I'm not clear what your trying to say. The OP's screen grab show every single process but one sitting at zero CPU usage. The one process using CPU is the window server, and that is only using CPU cycles to constantly redraw the Activity Monitor window that is running. He has an Air with no secondary GPU.
I had a 2009 MBP a while back that experienced major battery issues. The battery would drain faster than it should have, and then at 30-40%, would go to zero and shut off instantly. It was 1.5 years old at the time, no longer under warranty, but Apple replaced it for me for free anyway. They do stand behind their batteries if they are actually defective, as mine was.
Your issue may be a defective unit - but it might also be a software problem, as many people have already suggested. The only way to know is to take it to Apple.

What isn't true was your statement that screen brightness doesn't matter in determining battery life from a charge. It absolutely matters.
What these screenshots don't show is during that time what your screen brightness was, if you were using Bluetooth and WiFi, what websites you were browsing and if they have Flash content or other multimedia content, what other processes were running during that time, etc. As I said before, there are many factors that impact your battery life from a charge. You have to look at all of those factors together.
Yes, it shows on the Menu Bar if you have those on at the time of the screen caps, but it doesn't show if you were using them or how much during the entire time between screen caps.
no offense but honestly GGJstudios - I don't know what you're trying to prove here? I mean even if I did have flash related things open in my browser that wouldn't lead to the loss of 80% in 1 and a half hours.
I don't know what you're trying to tell me. Obviously there is something wrong with my battery or either it's a software related issue.
You've told me before you think that it's a software related issue and in response to that I asked - what do I do about it then? You still haven't told me what I'm supposed to do but you keep on trying to find ways to prove to me there's nothing wrong with my battery when quite clearly there is.

I'm not trying to prove there's nothing wrong with your battery. If you suspect the problem lies with your battery, rather than posting about it here (which won't fix it), take it to Apple and let them check it out. However, a failing battery isn't the only possibility. There are many other possible contributors to a rapidly draining battery, including screen brightness, processes running, etc. These factors are far more common causes of rapid battery drain than the likelihood of a bad battery. Prudent troubleshooting suggests you look at all factors, rather than discarding them without investigating.
