apple claims 10H battery on these things


thanks in advance,

LOL Depends on what you are doing with it. Apple's battery tests are performed with ideal conditions. Real life is always less.

For instance my 2009 model claims 7 hours. I got about 4 hours. I get about 5 now that I have uninstalled flash.

Skype and Garageband use a lot of resources, and which websites you visit may, as well, especially if they have multimedia or Flash content. Read the link I posted for Apple's conditions used to achieve their advertised time on a charge.
 
Configure the battery. My reported battery life improved after I did it.

Anyways, I get around 6-7 hour on an identical model with web browsing (no Flash), music playing through headphones.

how do i "configure" the battery? ps. its gone up to 4:30h lool! but still it should b more..

No, you can calibrate it anytime. Do that first, so you know your readings are accurate.

I'm sure they meant "calibrate", since there is no way to "configure" a battery. Do yourself a favor. Read the Battery FAQ I posted. It really will answer all your questions. After you read it, if you have more questions, ask here.

ill calibrate it at 2nd charge... is that ok?
and yes i have read the battery thread.. :)

Yes, as long as you follow the calibration steps in that post exactly, you can do it at any time.

If you read that FAQ, then you know that your time remaining is an ever-changing estimate, based on the current power demands of your system. The estimate will go up and down as your workload changes.

ok, thank you so much!!

Just a question..
in steps 4-5..
4. When you see the low battery warning, save your work and close all applications. Keep your computer turned on until it goes to sleep.


5. After your computer goes to sleep, turn it off or allow it to sleep for five hours or longer.

so, after it goes to sleep..( because of no battery) do i let it rest for 5h or more?
 
If I am continuously working on mine, it tends to last about 4-6 hours, depending on what I am doing. If I ever play games that seems to drain the battery extremely fast and I will have to recharge after 4 hours.

Hello i just put post on the same issue, i bought a MBP 15 and the battery is empty very quick. after 4 to 5 hours that,s less then apple tells people in the site. So what to do?? or is this normal after watching You Tube and surfing on the internet!! I just want to let you know that i have the same problem , it makes me feel bad

Watching videos (flashplayer) increases CPU use. Increased CPU use means the computer is working harder, which decreases battery time.

Keep an eye on time remaining. It will decrease quite a bit while watching a video. Now quit watching the video. After a few minutes you should see your time remaining jump back up a bit. Just the way it is.

Apple's battery time is the MOST it could possibly get. However, running any applications will decrease this time. Any application that is CPU intensive will lower the battery time even more.
 
Yeah as long as you let it unplugged for atleast 5 hours, you can charge it as long as you want after that. But it has to stay plugged in until fully charged.
 
very well, now i have to wait 5h.. is there a problem if the MBP Charges all nite?
As the Battery FAQ states:
CHARGING

...When it reaches a full charge, the light on your MagSafe adapter will turn green. This indicates that it has stopped charging your battery and you are now running on A/C power with a fully charged battery. It will not overcharge your battery. It's also perfectly safe to let your Mac notebook sleep with A/C plugged in.​
 
is it ok if i never shut down my mac.. if i only sleep it?

think about it this way. do you need sleep? YES. similarly the computer also needs a good sleep. and this is called "shutdown" not the weird term sleep (why someone would say that is just plain ridiculous)

all in all, shut it down. the computer needs rest like you do, and the sleep function is for "temporary" usage. like you will come back to it after a few hours.
for the longevity of your computer, it is recommended you shut down your computer.
 
I would assume it is ok from my personal use. The longest my MBP was turned off when it was in my possession was when I changed hard drives which was a whopping like 20, maybe 21 minutes lol

Whenever I use Skype my battery tends to flatline as it and some websites are continually using resources where as sites which you just read load and use resources for a much lesser time in comparison to when you are reading through an already loaded website.
 
is it ok if i never shut down my mac.. if i only sleep it?
Yes, it's perfectly fine to sleep vs shut down. Many Mac users go months at a time without shutting down.
similarly the computer also needs a good sleep.
Completely untrue.
and this is called "shutdown" not the weird term sleep (why someone would say that is just plain ridiculous)
There is a sleep mode. That's what it's called. It's not ridiculous, but your comparing a computer to a human is.
think about it this way. just like you need to sleep for hours and hours, so does the computer.
No, it doesn't. It's a computer, not a human.
although the sleep mode on the computer does allow it to "sleep' it still has things running.
When your Mac is in sleep mode, nothing is running.
all in all, shut it down.
Absolutely not necessary.
the computer needs rest like you do
No, it doesn't.
for the longevity of your computer, it is recommended you shut down your computer.
There is no such recommendation.

A computer can run for years without shutting down. It does NOT need rest, like a human does. It is not a living organism. It is an electronic device.
