MacBook Pro :: How Long Does The Battery Last For A Unibody

Sep 11, 2009

I have a 15" MBP (2.66Ghz, late 2008), I usually don't have WiFi turned off, so I just wanted to know how long does it usually last with WiFi off and semi-high brightness setting for the display. The only activity is typing in Word and maybe a few non intensive Photoshop stuff.

I'd like to get an estimate because I have no power adapters where I'll be using it.

MacBook :: Battery No Longer Holds Long Charge / Worth Pursuing A Replacement Battery?

Jun 2, 2009

purchased a macbook Unibody back in October 2008 when they were released and use it heavily. The battery no longer holds a nice long charge - I get about 2 to 2.5 hours out of a full charge.

The battery has 149 cycles on it, which is obviously high (and correct, I use the hell out of it). With it still being in warranty, is it worth pursuing a replacement battery? Will Apple tell me to go take a hike with the high cycle counts?

MacBook Air :: How Long Should Battery Last

Feb 13, 2009

im just curious (and maybe a slight bit worried) about how long my macbook air should last on a full battery. it seems like it gets less and less all the time. its not my primarily used cmputer (i use my iMac mostly) but i still use my MBA most days whether it be in bed or on my travels to friends' houses etc.

when i do use it ive usually got a socket handy so its always charging and when its in the house not being used, its pretty much always on charge which means the battery running out isnt a big deal but the few times i actually don't have the MBA on charge it seems to run out pretty quickly. i do tend to run a lot of programs, however.

MacBook :: Battery - Memory On Unibody ?

Feb 4, 2009

Do the batteries on the unibody develop a memory like cell phones do if you keep charging them before the battery is drained completely or almost dead? I don't want to kill the battery life and was just curious if apple had maybe done something in the cpu to control that?

MacBook Pro :: How Long Does 13" Battery Last

Apr 23, 2010

Mine only lasted 2hrs 30min on full charge (4th cycle. 4 day old), did the calibration and then it's now lasting about 4 hours. (it showed 7 hours in the beginning but number changed quickly as I opened Safari and browse online)

10 Hours? Come on Steve! Even with the dimmest light, bluetooth off, wireless off, no application running i've never seen 10 hours on MBP13". Not even 9 nor 8.

And I found this article.
"Macworld's 13"MBP Review: The 10-Hour Battery Lasts Four Hours"
(URL)
At least the author was playing Quicktime video...me? Nothing much and 4 hours. (Factory defect?)

MacBook Air :: External Battery For Long Flights?

Feb 21, 2008

What do you think about this battery from Batterygeek?

Specs:
130 Wh
16 or 19 volts output
1.7 lbs

This should give 4.5 times the normal operating time. Should be possible to watch demanding movies for about 7 hours, or do less demanding things for 18 hours.

I'm not sure if the voltage is too high or within limits. The Air magsafe seems to output 14.5 volts.

MacBook Pro :: Battery Capacity - Not Lasting Long

Feb 21, 2010

I have noticed that lately, my MBP Mid-2009 battery isn't lasting as long on a single charge as it used to. So, I downloaded and ran coconut Battery (attached results). After 152 Charges - I'm getting 90% battery capacity. Is there a way I can improve on that. Or, is this number about right for the age of the MacBook Pro?

2008 Unibody MacBook Pro Shuts Down When Lid Closed While On Battery

Jun 12, 2012

I did some google searches, but could not find anything that was exactly my issue. I have a 2008 MBP unibody. If the MBP is on battery only and I close the lid, the notebook shuts down completely. This is even when the battery is fully charged. However if while plugged in and I do the same, the computer "sleeps" as advertised. I have reset both the SMC and PRAM to no avail. The main thing that bothers me is it seems like when this happens on battery, its almost as if the computer is getting a hard shut down. The machine acts as if the battery was pulled while the lid was closed and this is obviously not good for the hardware or sofware.

MacBook Pro, Mac OS X (10.7.4)

MacBook :: Maximizing Long Term Battery Life?

Dec 12, 2008

I have a MacBook and my strategy is to keep it plugged in as much as possible to avoid using charge cycles. If I use it down to 50%, then get home, I'll plug it in so I've only used half a cycle. Then when I'm just using it around the house, I try to keep it plugged in.

My friend has a completely different strategy. At the Apple Store, one of the salesmen told him that he should use it down to almost nothing and then charge it back up again. He would never plug it in at 50%, but wait until it is 10% or less. He gave me this analogy: if you have a bottle of milk in the refrigerator and you have a cow outside, you refill the bottle when it is empty. If you keep refilling the bottle when it is only half empty, that milk is going to go bad. He really doesn't understand how it works himself, but said something about the battery's memory? I never imagined that a battery would have its own little memory or something, but now that he mentioned it, it does seem reasonable.

MacBook Pro :: Takes Really Long Time To Restart After Battery Drain

May 13, 2012

Last night I had a weird experience with my mid-2011 MacBook Pro; I went out to dinner and came back to find the cat had kicked the power cord out, draining the battery. I've had this happen before and wasn't too worried; it's always just restarted after I plugged it back in. This time, however, I plugged it in (getting, perplexingly, a green light on the cord) and nothing happened except for the sleep light slowly flashing; it didn't respond to any pressing on the power button, and the sleep light disappeared if I unplugged the cord. The battery test button on the side got one flashing light (meaning, I believe, a dead battery), which also didn't work if the computer was unplugged.

I left it plugged in while I hunted for info on the problem and about an hour later had just decided that I was going to have to take it in to the Genius Bar when it suddenly booted up. The cord light turned orange and it proceeded to fully recharge over the next two hours.Is this normal behavior after a battery drain? Should I be concerned? Is it worth taking the computer in to get the battery checked, or some other element of the comp? (some of the things I looked at were talking about the logic board, which is not a happy thought)iStat Pro claims the battery is at 41% health, 111 cycles, which I would think would mean it has some life in it yet.

MacBook Pro, Mac OS X (10.6.7)
