battery life

I recently upgraded my Macbook Pro (was bought in 2006) with a bigger hard-drive, more RAM, and installed Snow Leopard. (10.6.8) I also got a new battery because my old one was only holding 40 minutes of charge (while computer is idling) which is not enough for my uses. Before I go on...

I made the mistake of letting my battery run out when my computer was running (though I kid you not, it was for less than a second,) and now its run time is ridiculously short. Before my stupid little mistake, it would run for upwards of 3 hours, now I'm lucky if I get 30 minutes out of it...

Yesterday, I had to change the batteries on my Apple Bluetooth Wireless Keyboard, for the first time since I purchased my iMac in September 2004. That makes 18 months running on a single set of batteries. I can't but think that this pretty impressive. I use Energiser E2 Lithium batteries -...

Hi All, I own a 12" PowerBook G4, and as I'm sure you all know -- it gets LOUD, hot and has horrible battery life. Since Apple hasn't posted battery life for the new MacBook Pro (even if they did, would I take it seriously?) does anyone have any predictions on this (and the noise and heat...

Hi don't know if this is an issue but I suddenly have short battery life after upgrading to Tiger. When working off the battery I can only get about 20 minutes and then goes into sleep mode or just shuts down. When charging it can suddenly charge back to 100% in a matter of 20 minutes. Is...

...is down to 2hrs 50mins. The peripherals attached are an Apple BT keyboard and an external display. Would this cause such a reduction in battery life? I've also noticed that the battery level of the keyboard is down to 60% 2 weeks after starting to use the keyboard. I thought the batteries on...

This battery on this new powerbook is pretty new. It's been calibrated. It's on 10.4.1. But even when I put settings on maximum battery life and turn off both airport and bluetooth, I only get about 3.5 hour battery life? Yet, apple advertises 5 hours. I want my hour and a half back!

Hey everyone! I was given a new iPod mini as a Christmas present a few months ago and, being a musician, was thrilled with it. But I noticed over time that the battery life seemed to shorten. I expected it would do so, as we all know, because batteries naturally lose their capacity as they are...

My only experience up until recently with a wireless mouse was a Dell Mouse on my Windows box that I rarely use. Since I got the wireless setup, probably 8 months ago, I have yet to replace the battery in the mouse. A month ago, I got a Bluetooth Wireless Keyboard/Mouse combo to cord-free my...

I see that they raised the battery life estimate on the new 20Gb ipods (not photo) to up to 14 hours of battery life. Could anyone make an educated (or non-educated) guess as to what this will translate to in the real world for listening to music... while new and also a year down the road ...

I have a G4 12" 1.33GHz laptop, as well as a G4 15" 1.33 GHz. The 15" laptop battery seems to die much quicker than the 12". Is there a way to sustain the life of a bettery before recharging it? Thanks Dean

I have questions/remarks about battery life of the iPod. I own an iMac (G4) and have my iPod connected to it. Several things I have noted about the iPod, its battery life, the battery meter and the way it is connected to my Mac. 1. Every time I start my Mac and I have the iPod docked in its...

How long is the battery in a powerbook G4 supposed to last as mine seems to last approximately one hour whilst running and using Photoshop. Is this normal? Also, does anyone have any tips for extending battery life.

Apple recommends disconnecting USB devices to conserve battery life. Any idea how much time a wireless mouse is gonna suck out of my battery? I'm looking at Logitech's Wireless Notebook mouse in particular. Thanks!

My Powerbook's battery life seems to be dwindling. I used to get somewhere from 2:45 to 3:30 on a single charge. Now I get about 2:20. After running the commands "ioreg -l | grep -i IOBatteryInfo" in Terminal, I see that my capacity is only 3664, when it should be above 4000. Now, what can I...

Is it true that to extend the battery life I should never shut it down and keep it on sleep while I dont use it? anyone know how to preserve the battery on ibook? thanks!!!!!!

Go to terminal (located in your appications>utilities folder) and run the following command " ioreg -l | grep -i IOBatteryInfo" the response will look like this "IOBatteryInfo" = ({"Capacity"=4144,"Amperage"=1200,"Current"=160,"Voltage"=11431,"Flags"=1090519175}) the flags will...

I'm really new to al this, but approximately how long should a battery last for a mac? not in terms of like until iit goes to sleepor runs out of juice, but like until it's dead & you can't use it anymore. Unless that is not possible, 'cause you're charging it right.
