MacBook Pro :: After First Time Battery Calibration, The Battery Time Left Icon Is Not Right?
Aug 17, 2010
calibrating my battery for the first time this morning. i just opened my macbook pro to see that the time left icon jumps every minute. it goes from 8:50 to 12:38 to 6:54 to 11:37 to 7:40! and now it went from 8:45 to 9:19! the percentage remaining is consistent and correct but the time left is way out of whack! sorry for the slang! now it went from 9:19 to 9:11 then 8:47. i have the screen at the lowest brightness, no backlit keyboard, nothing else running except firefox. i wasnt aware that i was supposed to calibrate my battery and its been about 3 months since i bought this. now its at 8:37 now 8:18. this is quite
I have had my macbook for just 6 months....at the beginning it was perfect with a very good battery life.Now at 99% charge (as it refuses to finish charge to 100%) It now says 10:00 where the battery time is and last less than 30mins.
Also its charge capacity is JUST 708 !!!!It was over 4000 just 6 months ago.Im sure my battery is on its last legs, anybody know if I am entitled to a free one?
Charge Information: Charge remaining (mAh):708 Fully charged:No Charging:Yes Full charge capacity (mAh):708 Health Information: Cycle count:110 Condition:Check Battery
I've had my unibody 2.0 since November. It's always said 5 hours or so when i open it up fully charged. This week it's started fluctuating wildy. While typing this post it's gone from 3 hours 23 mins to 4 hours and five mins....it started at 2 hours....now it's up to 4...very odd. Any ideas on why this has started happening all of the sudden?
I have just completed rescuing a water damaged MB C2D which was originally a 2.16 and is now a 1.83. Fun project for a cold Sunday afternoon. 5 hrs I have one issue with the MB and that is the charging of the battery. The battery icon sometimes shows 'no battery' or if it shows a battery is recognized, it isn't charging. The LED on the mag-safe charger is always green. The battery is from the water damaged 2.16 and my thinking is that it may have suffered damage from being exposed to water. Original owner left the MB in the backyard and it started to rain!
When calibrating the battery, is it better to do a quick drain with a dvd or cd burning or a slow drain with the brightness all the way down or does it not matter?
I've got my SSD in an optibay and am using it as my boot drive. As such, I've disabled hibernation on my MBP.I am wondering about battery calibration, as you need to drain the battery down fully and have the MBP enter the hibernation state to properly calibrate the battery.
got my 13" MBA and am very happy about it. I plan to baby this thing, and I am always very conscious of battery life for all of my devices, so do any of you have any advice for how to best handle the first charge/discharge cycle?The machine almost fully charged out of the box. Should I run it down to zero and then fully charge it? Should I fully charge it first and then run it down?
So I just got my macbook pro yesterday 2.8ghz. quick question. I just read up on the battery calibration process on apples website. seems straight forward. just one question. after i let the battery drain and let it go into sleep mode, then wait 5+ hours, then charge it to full. can i use the computer when i start charging it to full? or does it have to be off while im charging it to 100%? t
I just got my first Macbook pro 15" and trying to calibrate the battery. Can my MBP sleep on battery during calibration? Can i finish the process after sleep? It takes a lot of time to calibrate this device.
I just got my first Mac yesterday, 13" MacBook Pro. I LOVE IT! I've been trying to find out some info on the battery calibration that I can't find anywhere. I have tried Apple's website, Google and MRoogle before I made a new thread about it
Ok, so I just did a battery calibration and once the battery got really low, it shut off, but didn't go to sleep like it has done before. It completely turned off; the battery light indicator is not indicating it is asleep. I've never seen it do this, has anyone else had this happen? I have a 2006 MacBook Pro, 2.33 C2D, non-unibody.
Well I just scored a 15 inch 2.4 from Bestbuy for 10% off. SOmebody just returned it having never even used it, but they had to discount it because it was opened. I love it love this thing!We did migration from our imac and everything came over. AmazingOne question about calibration. I charged it fully and let the power cord be in it for an extra 2 or so hours. I then used it unplugged until it basically shut off due to no power. Cant I just plug it in and let it charge all the way without letting it sit for 5 hours. Its not sleeping I dont think. It actually shut off suddenly as it was at zero percent. There is no power to it at all that I can tell. Will charging it now without leaving it unplugged for 5 hours ruin the calibration??
I've just calibrated my battery on my 2.4GHz MBP (let it run out until it slept, then woke it up, then used it till it shut down, then charged it) and it's stuck on "finishing charge". Additionally, the battery health has gone down to 23% from 37% since I have done this.
I was sick of the battery life I was getting on my 15" Macbook Pro 3,1 (early 2008 model), so I went to the apple store yesterday to get a new one. I was over 400 cycles, so I had to just buy it, they wouldn't replace it for me. I expected that, so no big deal. But I wanted to treat this battery right. I got home, charged it up to 100%, let it sit at that for a few hours, and then let it drain overnight and rest at empty for a few hours. This afternoon, I plugged it back in with the intention of letting it fully charge and thus complete my battery calibration, but at around 40% charged, the cat yanked the charger cable out from my laptop. And then a little bit later, my girlfriend did it again. So, has my time been wasted here? Battery calibration is such a pain in my rear. i hate it. I use my laptop often and expect it to be available to me whenever I need it, regardless of how many other computers i own. I really don't want to deal with it again in the near future. And I may not.
So I just got my first MBP, and I have calibrated my battery. Both iStat and Coconut Battery report my battery health is 98%. Do you think this is reason for concern, considering the MBP is supposed to be new? What is your new MBPs battery health?
Last night I calibrated my battery. Let it fully charge for 2hrs, took it off the charger, turned up the screen brightness and keyboard backlight all the way, then proceeded to run the battery down watching videos and whatnot. It went to sleep and I went to bed to let it sit for 5 or more hours. Woke up, charged it up, turned it on and noticed that I went from 97% to 87% (coconut battery says 86%) and I only have 54 cycles. Should I go to the genius bar or something? Or try re-calibrating the battery? Did I do something wrong when I did it? Does it matter how long it takes to run down the battery after it's fully charged?
I just bought MBP 17 i5 model a couple days ago from a local apple store(Keystone Mall). and I calibrated my battery yesterday. The thing is I know MBP should sleep when the battery is really low(running off reserve) then when the battery drains out, MBP should do the "safesleep" thing where it stores the current state of the machine so that upon turning the machine back on by supplying the power to it or after charging, MBP returns to the stored state.
But, when i was calibrating my battery, I did get the low battery warning(reserve battery blah blah) but then it drained down to 0 then the screen flickered(literally made a flicking sound) and went dead. When I got up in the morning I plug the adapter on and turned the MBP on and MBP just freshly boots.. rather than restoring the previous state..................
I have a 30 month old MacBook Pro (the SantaRosa line from June 2007)... And was still using the original battery up until 3 days ago. Its capacity suddenly dropped from 83% down to 45%, so I took it to an Apple store, they did a diagnostic, and without question told me the battery was defective, and just gave me a brand new battery with only 1 loadcycle on it. So today I decided to calibrate it, had it charged up, unpulgged it and let it run until it was 'supposed' to go to sleep... It had 0% left on it, the screen shut off, and the sleep light was just starting to dim, when I heard the hard drive go . (As if one pushed and held the power button, aka hard shutdown).
It seems it didn't have enough reserve capacity to let it go to sleep, so instead of waiting the 5 hours (as it wasn't sleeping, and pressing the button on the battery showed no lights at all), I decided to plug it in right away. Would it be a good idea to calibrate again, or simply wait a month or so and do it again then?
When I turned the computer back on, it didn't even resume at my desktop, so not only did it not get to sleep properly, it didn't even have a chance to write the memory to the hard drive, and now the actual battery capacity in Coconut battery is showing up 95%, 5253mAh
Just curious, as 30 months ago when I first got my original one, it calibrated properly and didn't completely die when it got to reserve capacity...
My MacBook Pro is only 3 months old with 37 battery loadcycles. I calibrate my notebook monthly and the battery capacity stays the same. I have also tried resetting the SMC and nothing happened I do not have my laptop continuously charging, the most would probably 4 or 5 days straight. My current battery capacity is 91%. What should I do?
What's the best thing to do with the MBA out of the box? Should I use it and drain the battery to zero or not even turn it on and just charge it?
I want to treat it nicely from day one ...
Also, on the same topic of treating it nicely, do you recommend a screen or keyboard protector? I had a keyboard protector on my PowerBook G4 (iskin). While it kept the keyboard nice and clean, I suppose it didn't give me the best experience I could have had with the keyboard itself. I now realize that I can't really read the keys because the protector is so dirty.
I routinely put my Macbook to sleep with a full-charge at night, then unplug it (the power cord doesn't reach where I keep my computer at night). When I wake it up, it generally has 93% of a charge left. This has never happened and I am wondering if it is time to replace the battery.
I am totally new to macbook. After being a very supportive Windows user I finally decided to change that and get the Macbook pro 13". I was trying out the battery and wondering there a bit. I charged it fully and when I started running the mac on battery the remaining time showed around 10 hours, then it would start jumping, suddenly it went to 9:30 and further down. The lowest within half an hour use was 4:30 and right now it's up at 8:50 again. I was wondering whether this kind of "jumping" is normal or whether just my macbook is doing that? I am really happy with my decision so far, I love the macbook and I am sure while trying it out in the next week or so I will come up here with some more questions!
The battery time on my Macbook Pro 15" goes from one time to another in a matter of minutes. I fully charged the battery after it had been drained. This is what I mean by fluctuating:
I've been meaning to calibrate my computer for some time now, but it seems like a wee hassle. I ask you this: must I calibrate my battery? Will it in any way affect my battery life during one cycle? What about the overall life of the battery in terms of number of cycles?
I'm in to buy a second hand Macbook unibody - the one that didn't exist for very long, until it was slightly upgraded and rebranded as Macbook Pro. 13,3".
Differences I've found so far add up to these: 45 watt changeable vs 60 watt built-in battery 2.0 Mhz vs 2.26 Mhz - vs Firewire 800 and SD card slot
One question would be - how much does the battery time differ between 45 and 60 watt?
Then I heard that the screen might have been updated too, something that for me makes more value than all the above. A quote comparing the white Macbook ("WhiteBook") with the unibody Macbook pro: "While both machines have 13.3-inch glossy displays, the unibody has also been upgraded to a higher-quality screen from AU Optronics with 60 percent greater color gamut, another advantage over the WhiteBook."
Does the unibody Macbook have the same screen as the white macbook, or does it have the same as the unibody Macbook pro - or something in-between? Does someone know of a comparison between the two?
I'll do a lot of graphics - picture editing - so it's important for me.
In the coming days I am supposed to be in delivery of my new MacBook Pro and was wondering if it is better to just use the built in battery to power on my MacBook Pro for the first time and just power it off the battery until the battery is fully discharged? Or should I power my MacBook Pro from the power adaptor?
My new MBP has 5 hours of battery when doing light web browsing at medium brightness. Only 2-3 hours when playing low res youtube clips, and 6:45 hours with all apps and wifi turned off and screen brightness at minimum.
When I first turned on the MBP I charged it to 100% and then discharged it down to 0. Is this battery life normal? What happened to 8-9 hours with wifi and web browsing? I can't even get 7 hours with everything off!
I have a rev B MBA, which is gorgeous but I have found myself using it less than any other Laptop I've ever had and it is simply due to two reasons:
- Heat, pretty much anything except simple browsing raise the heat - Battery time, simply lousy (including charge time)
Have had it for a while, 14 months, but at this point I have started looking at the 13 and 15 inch versions as replacements down the road. I thought it would make a great compliment to the imac but due to the limitations above I use it less and less. If only they had added a fraction of an inch of thickness to allow better heat handling and more battery.
