I am on my replacement battery and am concerned about battery life issues again. The other night it seemed that the power went pretty fast, but I hadn't timed it. I was just surfing while watching TV. Today I timed out at just under two hours, again mostly internet use and even probably 20-25 minutes of sleep in there. Considering that, this seems awful. All firmware updates have been done and I think I have reasonable battery management settings.

Try optimizing your battery following these

Thank you. Sorry that I failed to mention that I did do the battery calibration procedure with this battery after receiving it. I suppose I could do it again, but I seem to recall it wasn't suggested as being needed even as infrequently as each month if the computer is kept busy every day. Mine certainly is. Am I wrong?

On the page you referenced it says Apple doesnt recommend leaving the laptop plugged in, that it's best to "keep the electrons moving." I'd really be interested to know if MBP owners are actually doing this, i.e. running on battery whenever possible, even when in the office or otherwise near a handy AC source.

I'm getting 90 minutes to a battery. This is not acceptable as I need 2 1/2 hours. I'm not using Shake or FCP on a battery. Mail lists, script writing. Thing you could do an a 99 cent dell laptop. I had one of the first TiBooks and got use to long battery life.

And sleep. Have to close everything down to get it to sleep or it won't sleep.

As a result I have to use this thing plugged into the wall. So I'm going back indoors to my G5 desktop to work.

I've done everything this list suggested. Airport off, re-cycle battery (twice) Bluetooth off. Widgets off. Everything off. Still only 90 minutes.

The battery is not a recall serial number.

Say you are using your MBP for 10-12hrs per day in one sitting and you start at 100% of battery power. Would it be better to discharge, then recharge, discharge, recharge, etc..OR...To run it on AC and just discharge and recharge your battery once per day? Apple recommends not to keep it on AC charge all the time. So to me that would mean that you would need to keep it running off the battery and not on AC, therefore you would constantly be recharging your battery. The problem with that is Apple also said that the average cycle count is about 300 full charges then the battery will go down to 80% of battery power. It doesn't take a very long time to reach 300 charge cycles. Does any of this make any since?

I agree that something's rottten in Apple's Denmark. My Apple-replacement battery zooms down. My settings are Apple's own "Better Battery Life." I have calibrated, etc. etc. And the point about how if one follows Apple's own advice about "keep the electrons moving" and follows the battery-AC-battery-AC-etc. routine, one quickly reaches 300 charge cycles.

It would seem we not only have to buy a 2nd battery and lug it around (better start now rehearsing how you're going to explain this to the airport's TSA folks...), but we have to be prepared to just keep on buying batteries as the present ones reah their optimum charge cycles.

Yes, gloom-and-doom rhetoric from me but it feels that way!

hi, i got a macbook pro a few weeks ago, and over the past couple of days iv noticed that my battery life seems to be around 3 hours, and this is with me surfing the net and thats all. i see how everyone keeps saying oh thats bad etc but noone has given any idication of roughly how long a battery life should be, so could someone give me some kind of rough answer, 3 hours? 10? im just worried that when i go back to uni and use all the CS programmes my battery will drain really fast... im really hoping i dont need to do a swap coz it seems quite a lot of hassle!! oh and iv calibrated my battery.

The September issue of Consumer Reports reviewed 21 Laptops, Apple being one of them. The battery life ranges from 1 3/4 hours to 4 hours, the average is about 3.5 hours for most of them. The MBP 15", 17" and the Macbook all come out on top in general. I am just going to discharge and charge the battery once daily. Forget about Apple's round about cycle of charging a battery.

reading all this I m paniking....means that all batteries are pretty different them.....how is this possible ?
Any way I v calibrated my MBP 4 times.....usually I keep my mac pluged in cauz wen I use it on batteries it keep runing max las 1 hour .
Probably I need to call apple care.
Any way is a bit disapointing...
