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?
View 7 RepliesJust bought a new 15 inch retina MBP. My question is...should I immediately charge the battery or let it run to zero first and then charge it? Does it even matter?
Info:
MacBook Pro with Retina display, iOS 7.1.2, Retina, 15 Inch
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?

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.

View 4 Replies View RelatedWhen you see the low battery warning, save your work and close all applications. Keep your computer turned on until it goes to sleep.
After your computer goes to sleep, turn it off or allow it to sleep for five hours or longer.
Connect the power adapter and leave it connected until the battery is fully charged.
I calibrated my battery for the first time since Dec. When I plugged it in this morning, it took 3 hours to charge all the way, and now it's stuck on 99% full, 0:00 till completely charged, and I'm getting an error when I click on the battery in the menu bar that says "Service Battery". When I click on the error, it tells me that it may not be functioning properly and to take it to an authorized apple service retailer. Before I waste 2 hours by going to the Apple store and back, has anyone else had this problem, and is there a way to fix it without having it looked at?
View 4 Replies View RelatedIf you look at apple's battery life page it states the MBA battery is removable, I thought it wasn't supposed to be?Battery Lifespan For Apple notebooks with removable batteries ? such as the MacBook, MacBook Air, and 15-inch MacBook Pro ? a properly maintained battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.
View 1 Replies View Related 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?
been using my older MBP with windows 7 for a while and have never notice oddies with the battery until now. Then recently after replacing the failed HD and re-installing Snow Leopard on my 2007 MBP, the battery panel is telling me "Service Battery"; it's battery health according to coconutBattery is fair for it's age (50%).
the unit (battery) has been replaced previously due to being considered 'under performing'. Is Snow Leopard trying to encurate it's users to replace the battery more frequently? If not, does anyone know why this appears? I'm at lost, since it appears to work fine, if not charging completely.
I just want to make sure nothing else is wrong with my Macbook..have never replaced the battery in 3+ years...Always says not charging and once the magsafe is removed Pro shuts off...is completely dead battery the only problem..?

So, I randomly clicked on my battery and noticed this "Service Battery" message. I had never seen it before. Obviously, this isn't a good thing. My Mac is 3 and a half years old so I'm not surprised this message poped up. So, I opened Coconut Battery and noticed my current battery capacity is at 65%. Even though charger says it's green, my battery isn't even charging. Should I make an appointment with Apple? My AppleCare expired so i'll have to buy a new battery when the time comes. I'm sure they're not cheap, either.

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.

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??

View 1 Replies View RelatedI'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.
View 10 Replies View RelatedI 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.

View 3 Replies View RelatedLast 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?
View 10 Replies View RelatedI 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..................

View 5 Replies View RelatedI 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?

your battery drain in your laptop to 0, and then charge it to full? I am under this assumption. Please let me know if this is wrong.Anywho, so today I decided to let my battery drain to 0, and then normally it would sleep and I'd wake it up after plugging it in.. but this time I had to actually press the power button, and a gray screen appeared with a meter-like thing to illustrate it "waking up" I guess?

I have a Mac 10.6.8 running Snow Leopard. My battery won't charge: all I get is "Not Charging" in the menu bar battery status; the power adapter doesn't light up either. It's not a problem with the battery—when I put my battery in my friend's MacBook, it worked just fine. His battery, however, wouldn't charge either when it was in my computer. I have tried resetting the SMC several times, following the instructions exactly. I've reset the PRAM, run disk repair, and fixed disk permissions. I don't have the money to take it to a repairman—even if I did, I need my computer every day for work.
