MacBook Pro :: Battery Seems To Lose Charge Quickly With New Mid-2012?
Jun 17, 2012
I recently was able to upgrade from a MacBook Pro Mid-2010 to a new MacBook Pro Mid-2012. I've only been using the laptop a few days, but it seems like the battery goes down from 100% very quickly. For example, right now I've only been using the computer for half an hour and the battery has gone from 100% to 71%. I haven't been watching movies, etc., just browsing the web.
So I usually keep my UMBP plugged in at all times. It unplugged by accident and went to 99% so I left it unplugged but literally less then maybe 7 minutes my battery is already reading down to 92%. Brightness on screen is set all the way up, if that has anything to do with it.
I just bought a new MacBook Pro with a solid state (flash memory) disk. The battery life is good while I'm using it, but if I leave it with the cover off for a few days (asleep, I assume), it'll be mostly discharged when I open it up. I assume this isn't normal - it shouldn't be losing that much charge when closed and hybernating. I don't have "wake for ethernet access" checked, if that makes a difference. What's going on - why won't it hybernate?
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?
Info: MacBook Pro with Retina display, iOS 7.1.2, Retina, 15 Inch
-Model Name: MacBook Pro -Processor Speed: 2.8 GHz -Memory: 4 GB -OS X Version 10.9.3
When starting up it must be connected to the charger and when i turn it on it makes the bing noise, goes to the apple screen with the wheel turning for a second and shuts off. I have to do this multiple times until it works. Another issue that I am having is that the battery is draining very quickly. I just had it replaced a couple months ago.
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?
I bought my Macbook Pro 13 inch last year in August. The health is on 88% with 84 cycles. Original battery capacity 5450 maH, current battery capacity 4809 mAH (Coconut and Istat Nano). I just read in another thread that there are users who have higher health capacity with many more cycles! I took it to the Mac store in Bangkok two weeks ago since I believe that my battery drains quickly. They run a test and told me that my battery is healthy. Then they also downloaded some updates for my Mac and run disk repair under disk utility. The technician told me that these are heavy programs and if they battery drains very quickly there is something wrong.
But according to him this was not the case. I have a 500 gb hdd and the technician said that since this is a big hdd (he recommended 320 gb maximum for 13 inch macbookpro), it will use more battery usage. I don't use heavy programs, only internet (Facebook, gmail, very seldom watch movies, watch news papers), Itunes and sometimes Word. I do a lot of photo processing, but this I always do with my adaptor plugged in. I think I can only use around 3 hours. Sometimes 4 hours. Screen around 80% brightness. Keyboard lights, bluetooth turned off. Do you think that there is a problem with my battery? Oh and I do calibrate my laptop monthly.
I'm trying to calibrate the battery of my new MBP. I need to get the battery to fully discharge and sleep for five hours or more. What are some things I can do to get my battery to discharge more quickly? Do I need to tell the MBP to not go to sleep after 10 mins of non-use, or the battery might last through the night? Or is it just the display that sleeps? I'd like to be able to use my MBP in the morning, but I'd like to make sure I get at least the recommended 5 hours of dead battery.
My MacBook Pro is 1 year old, almost to the day and my battery seems to be loosing all it's juice quite quickly these days. The battery cycle count is only 94. This morning I turned my computer on and I've only done emails. It's now about 4 hours since it's been on and I have 20% battery left. Bluetooth is turned off. Not doing anything any different than I used to. Seems to me the battery used to last 4 days for what I do with the computer. Now I charge it 2 or 3 times a day. I notice the underside of the laptop seems to get quite hot.
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.
For the past month I think I've kept my macbook plugged into the wall. And the battery meter now says 95% but it says fully charged and the green light is on? Is keeping it plugged in hurting my overall charge?
My friend has a late uMB and his magsafe port is very very lose. Coincidentally, his battery stopped charging around 10 days after. His computer always runs on AC power and it says the battery isnt charging but it gains around 4% every hour. He thinks its because the lose port, but I think something else is wrong. Anyone have any ideas?
I own a late 2009 MBP that I use with an external monitor as my work computer each day. At the end of the work day I generally unplug the network cable, Apple Cinema Display, and then just put it to sleep by closing the lid. Some days I use it later after I get home, others I don't. If I leave it in Sleep mode I generally lose about 5-8% of the battery by the next morning.
I'm just wondering if I'd be better off shutting it down completely each night. Any pros/cons? Battery considerations?
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.
The last couple of days my battery has been draining extremely quickly, at full charge it indicates that I will get about 2 hours battery life when previously I was getting 6 to 7 depending on what I was doing. Also, I have noticed that the fan is running almost constantly and at high. I'm running os x lion and this is a late 2011 model MBP 13".
Recently my battery seems to be draining faster than ever before. I'm not sure why. I haven't changed any "display" settings & it's on default settings for brightness settings, etc.
I have a macbook air 2012 with OSX 10.9.3. Until a few hours ago my mac was working fine. I turned it off and left it on charging for a couple of hours only to find that it had not charged at all. When I turned it on, it says battery not charging. I tried resetting the SMC and it did start charging the battery for a minute but again it stopped.
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 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.
having problem charging battery . sign just shows a cross on it.the lead shows green and will not go to orange,hence it is just working off the mains.Bought new battery, worked for10 days now having same problem.
I currently using a Aluminum MacBook 13' but I don't know which way is the best to charge the battery. - Plug-in AC supply and charge the battery while using OR - Take out battery and use AC supply while using
