Currently Being ModeratedJun 20, 2010 2:35 AM (in response to awan0912)Hi Mate,
I am having the same issue, i just realised once i read your post, after 3 cycles my battery is on 5536mAh and the battery health shows as 95%. I have properly calibrated the battery as per the knowledge base support. I use iStat nano to show the battery status. Has anyone else had any issues like this. Should i speak with technical support?
Many thanksMBP 13" 2010, Mac OS X (10.6.4)
Currently Being ModeratedJun 20, 2010 10:58 AM (in response to awan0912)I purchased a new MacBook Pro 15" yesterday with an i7 processor. I was told in the apple store that the battery life was expected to be from 8-9 hours. I charged it all night and unplugged it this morning. The battery life said it was full charged when I unplugged it. The percent then went straight to 96%. It's been unplugged for approximately 20 minutes now with average use (internet surfing) and the battery is already down to 90% and the battery time says 4:21. I'm thinking of calling Apple tomorrow and notifying them of my issue and seeing what their advice is.
Any advice?MacBook Pro 17" i7 Processor, Mac OS X (10.6.3)
Currently Being ModeratedJun 21, 2010 9:05 AM (in response to LandonL)exactly same issue with my new MBP 13' when fully charged then unplugged battery displays 96% hold only about 3.5 hours instead of 8-10 as my other MBP....2010 MBP 13', Mac OS X (10.6.4)
Currently Being ModeratedJun 21, 2010 11:42 AM (in response to awan0912)Hi awan0912,
One thing to note... Apple does not use a 3rd party application like iStat Pro or Coconut Battery as a means to determine machine performance or battery performance. Apple has their own application (that their technicians use in stores or at service locations) to determine battery performance. Apple states that their new batteries will maintain 80% (or more) of their original charge capacity at up to 1000 cycles. That being said... your machine meets that criteria.
On the other hand if you're not satisfied with your machine then I'd absolutely recommend bringing the computer in to have it looked at by a technician. That way you'll get an official answer and a resolution if one is necessary.13" MacBook Pro (2.4GHz/4GB/250), Mac OS X (10.6.3)
Currently Being ModeratedJun 23, 2010 9:09 AM (in response to awan0912)I am in the exact same position as you; i bought a basic 13inch white macbook last year in New York and it was awesome, but recently (about a month ago) I upgraded to a brand new 13inch macbook pro, but i'm convinced the battery was twice as good on my old macbook
I keep this macbook pro fully charged, and when i unplug it from the charger, and lower the brightness to 1/3rd, it never says the battery will last longer than 5 hours, usually 4 hours and 10 mins!
this must be a fault because this battery is meant to be better than my old white macbook?
i don't have apple care, what should i do?macbook pro 13inch 2010, Windows XP
Currently Being ModeratedJun 23, 2010 7:01 PM (in response to blood_secrets)Hi blood_secrets,
It's free to make a Genius Bar appointment and have them diagnose the machine. They can determine if your battery is defective or there's an issue with the machine. If the machine is older than a year with no AppleCare attached then you'd be responsible for paying for any service (or parts) outside of the initial Genius Bar appointment. But at least let a qualified individual determine what the problem is and then propose some solutions.13" MacBook Pro (2.4GHz/4GB/250), Mac OS X (10.6.3)
Currently Being ModeratedJun 23, 2010 7:33 PM (in response to awan0912)I'm possibly experiencing the exact same thing. I was fully charged and after BARELY 2 hours of using my laptop, I'm already down to 80% and fast falling. And just after 3 charge cycles, my Current Battery Capacity is now down to 96%. Should I be complaining or am I just paranoid? Are applications like coconutBattery and iStat accurate enough to believe them for their readings? By the way, I've only had my laptop 3 days ago and have yet to calibrate my battery. Thank you all.MacBook Pro 2010, Mac OS X (10.6.4)
Currently Being ModeratedJun 23, 2010 8:55 PM (in response to marcomp)You're paranoid. It's WAY too early for you to be obsessing over your battery. You've used 20% of a charge in two hours — that's ten hours on a full charge.

Currently Being ModeratedJun 24, 2010 9:26 PM (in response to eww)I guess you're right, hahaha! Although according to my coconutBattery, I'm down to 95% on my Current Battery Capacity with only 4 Batter-Loadcycles. Does this even make sense? Thanks.

Currently Being ModeratedJun 25, 2010 11:11 AM (in response to marcomp)Yes, it does. That figure will fluctuate up and down by several percentage points from day to day and week to week throughout the life of your battery. If it drops below 80% and stays there for longer than a couple of weeks before your battery has 1000 charge cycles on it, that will be the time to be concerned.

Currently Being ModeratedJun 30, 2010 9:10 AM (in response to awan0912)I have the same issue. After the second charge it went to 99 and then the third to 96. What I did next was drain the battery all the way down and chaffed it back up to 100% and it went all the way back to 100. Try this and see if it works for you. I believe that ut has somthing to do with by letting the battery discharging down before plugging it back into the power source. Email me at firstname.lastname@example.org if you have anyother issues or want more detailed steps to try and fix this.15" MacBook Pro 2010, Mac OS X (10.6.4)
Currently Being ModeratedJun 30, 2010 10:37 AM (in response to awan0912)I also have recently updated to a 13" MacBoook Pro, previously used a MacBook. I was used to bad battery life with my MacBook- my dad ran down the battery I think, so I was expecting great performance/life from a brand new computer but was disappointed right off the bat.
I just spoke with someone at Apple Support and he said that each time I use my laptop, I should use it down to 20% before I plug it in. He said otherwise, if I kept it plugged in all the time, when I was not using it that is, my battery could start memorizing these bad practices and for instances start thinking that a 90% charged battery was really 100%.
I dunno...anyway, what I wanted to ask was, is this true? Should I wait until my battery is at 20% before plugging it in? He said this was hugely different than letting the battery dip below 10% (he said below 10% and 0 were very similar) to recalibrate it.
I hope this makes sense...I know I ramble....

Currently Being ModeratedJun 30, 2010 7:35 PM (in response to MMulhern)No, it isn't necessary to run it all the way down to 20% before recharging. That will run your cycle count up unnecessarily fast, because you'll be using 80% of a cycle every time you recharge. Apple describes the ideal pattern of use for its notebook batteries as running the computer on battery power while commuting to and from work on a bus or train, and keeping it plugged in all the rest of the time. So if you run your machine on battery power for an hour or two every day or two, the battery will get all the regular exercise it needs without being cycled unnecessarily. If your work requires you to use it differently, by all means do what you need to do: the computer exists to serve you, not the other way round. But recognize that you may end up replacing your battery sooner than someone whose usage pattern is closer to optimal.
