MacBook Pro :: Charge When Battery Completely Drained Or At Any Time?
May 27, 2012
I have read about Macbook Pro batteries from apple.com. I use to talk to many people and ask about batteries which brought me upto this confusion. Well, my question is, should i charge macbook pro when it's battery is completely drained or it's okay to charge at any time as long as it's not at 100%? For example, I wanna start charging it while its 60% and make it to 100% or Don't charge it until battery reaches to 5 or 10 percent.

I got my first Mac last Sunday (woo!) but I was using it last night and a battery warning came up. I had been using the MBP, then turned it off and went out with battery still remaining. When I came back again a few hours later I used the Mac and after about 10 mins closed the lid for some reason. When I opened it back up it wouldn't start unless I plugged in the power outlet - the thing had completely drained. Then I checked the battery and it says to 'Service Battery'. It's now holding a charge as normal as far as I can see but the warning is still there.
A couple of other things I notice too:
- When I tilt the MBP to the right sometimes a scraping noise comes from the inside - maybe from a fan?
- When I pick it up from the bottom, the bottom of the Mac dips inwards slightly and there is a click as it makes contact with something on the inside of the case.
Are these things normal? I've made a Genius Bar reservation but I think I might just swap it for a new one.

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?

I was working late and let my battery drain while working. The computer shut down. I immediately plugged it in but the light on the power adapter didn't turn on (either orange or green) I tried other plugging it into other outlets. Nothing. I left it plugged in all night. Nothing. No light on the adapter and the computer isn't working.

My MacBook Pro is just under a year old.I don't do a lot of strenuous stuff... just internet, iWork documents, Sims 3, etc.The battery has been fine up until now, but on two seperate occasions it has completely drained in a matter of minutes.On the first occasion I left the MacBook open on my desk.No applications were open, just the desktop. Battery was at 98% after a full night's charge.I come back an hour later to find the computer completely unresponsive until I plug in the charger chord.It had completely drained.On the second occasion I was at 52% battery.I loaded up The Sims 3 and went to take a shower, planning to play when I got out.When I get out of the shower TEN MINUTES later, the computer was dead... once again completely drained.I know the game is a total battery hog, but I can usually get about an hour of gameplay with 52% battery.

rMBP charged overnight and I woke up at 7am and disconnected it, it is 9:30am and my battery is already at 34%. What ca I do? Only running Safari although a good portion of the morning was youtube videos. Still with some YT video playbacks here and there, should it drain this quickly?

Earlier this morning, I was using battery power until the power drained quickly and unexpectedly. Once it shut down automatically, I could not turn it back on. It does not run on AC charge or battery. The mag-safe light is only a faint green, and I have reset my PMU. I'm hoping to not have to take it to Apple as it's warranty ran out about two months ago.

I just popped in a brand new 15-inch MBP (square) battery into my 2008 MBP with Lion 10.7.4. It has drained to 84% in about 15 minutes. Is it a defective battery or a problem with calibration?

Late 2008 refurb Macbook Pro, 2.53ghz, Windows 7 RC (therefore forced to use the 9600 at all times). According to this report, the MBP got around 3&1/2hrs of run time with a dimmed screen and watching videos. From a full charge, I start browsing the internet (no videos at all), and my battery reading read as follows
91% 1hr, 16mins
90% 1hr, 20mins
89% 1hr, 24mins
87% 1hr, 23mins
Not only were the readings all over the place, but even from a full near charge I wasn't even getting an estimate of 2hrs, while Apple advertised 4 for the late 2008 model, and the review I linked to says they got 3&1/2. Do I have a bad battery, or does simply running the 9600 reduce the battery life by such a drastic amount? I have already calibrated my battery following the guide on the Apple website.

Just 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?Â

I was just looking at the battery info for my PB which is about 1.5 years old. It says that my cycle count is 59. I was wondering how many cycles the average battery will do with a reasonable charge time? My absolute max capacity is 4400. I found the information with the following command:
ioreg -l -w 0 | grep IOBatteryInfo

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?

If 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.

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.

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.

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. Â

Our old battery said it was needing to be replaced and my dad went out and bought a new battery for our 15" MBP from 2008 - running SL. I've put it in, it works, I've plugged the power cord into it, and the little light that indicates it's charging doesn't turn on. I checked in the menu and it said the battery isn't charging.
I've already pulled it out and then put it back in, shutting down of course. And I just tried resetting the SMC which has done nothing. It's not under warranty. I've just put the old battery back in and it doesn't seem to be charging it either. I'd be curious if the power cord was faulty, but it's powering the MBP at the moment.

ijust calibrated my batttery and my charger light is green which signifies its not charging anymore..and the icon at the top of my screen says charged..BUT Coconut battery says my current battery charge is as follows:
Current Battery Charge: 5807 mAh
Maximum Battery Charge: 5853 mAh

Original Battery Capacity: 5770 mAh
@100%
Additional Info:

so my battery charge is stuck at 99% and its been plugged in for the past 3 hours, and its saying my current battery capacity is higher than my original battery capacity.. is that normal?.. i cant seem to get my battery to 100percent and its not charging..
here is a screenshot of coconutbattery after calibration, i just got my macbook last week..should i be worried about the battery at all?

1) When you first get your Macbook Pro, should you let the battery die out completely and then fully charge it? Or should I charge it fully first? Or what? I don't want to mess up the battery with the first charge.
2) Do you leave your Macbook plugged in while you sleep, are not using it, etc? Or is that bad for the battery?
3) I've heard somewhere that it's bad to shut your Macbook off when you go out/go to sleep. Would it be wiser to just set it to "sleep" and keep it plugged in or something?

When the magsafe adapter is connected. Has anyone else got this problem. N.B. The charging icon in the top right hand corner only displays the words (Not Charging)Â I have been told by Apple Care to try a PRAM reset and a SMC reset, but the light on the mag safe never turns amber, just stay lit green.

I'm using a MacBook Pro 13' and it's one year old. I bought it last year March. But after I purchased it, few months later, my laptop started playing up. First, it's faulty hardware, and i sent my laptop in to get a new hardware. Not long later, the battery won't charge. Whenever I touch or drop the adapter or connecter when it's charging, my laptop will shut down itself, and resetting. (when i tried to switch on, the date has changed) And it won't charge anymore. I get frustrated when ever I ask for repair and it seems nothing happen in Apple Care, and they refuse to repair it.

My cat knocked over a glass of vodka/sprite onto my 13" white MacBook (the older version, from 2007 I believe). I let it dry out and took the battery out and everything and let it sit for a few days. It turned on when plugged in but the battery was dead. I purchased a new battery to replace it thinking it was just that the battery got ruined. However, the new battery I purchased will also not charge. It came partially charged and it worked and my MacBook had power without the power cord... until the battery died, and now i cannot get it to charge back up at all. Is this something that can be fixed? If so can I do it on my own or would I need to bring it to a Mac store, and what would that cost me? My concern about taking it in to get fixed is what it would cost me and if it is worth it seeing as my MacBook is pretty old.
