MacBook Pro :: 13" Battery (capacity Of 5393 MAh Out Of 5770 MAh) Draining MUCH Faster
Jan 7, 2011
It shows a battery capacity of 5393 mAh out of 5770 mAh with a condition of "normal" at 93% health. The issue is that the battery has been draining MUCH faster than usual. Yeah I know it depends on what I'm doing/Youtube/Flash blah blah blah. I get it. What usually took 6-8 hours of normal time to drain is now taking 2 hours, max. I reset the PRAM, etc --- not much different. Now, here's the BIG issue. I have NEVER been able to recalibrate my battery because after it hits 10-15%, the computer just shuts off. It never goes into sleep. This has happened every single time. Has this ever happened to anyone before? The Apple Store is ways away, and I don't want to waste time going if they're just going to tell me my battery is "normal" since I haven't hit my 80% health indicator.

Recently I've been noticing that my MacBook Pro's battery has been draining really fast. It's draining about 5% every 7 minutes. The battery condition is normal and it only has about 290 cycles on it. My brightness is turned all the way down, bluetooth is off and the only application I have open is Google Chrome, and I'm only using it to do some light browsing. Does anyone have this same problem? I have a MacBook Pro (mid-2010) running the latest version of Lion?

-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 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 have recently started using iTunes to listen to music while surfing the web or using other non intensive programs such as Inkscape. It appears that iTunes decreases my battery life considerably more than any other program that I use, even if I have a song on pause. While using iTunes my fully charged battery will display 4 to 3.5 hours of life remaining. When I have iTunes closed my computer will display a battery life of 7 to 9 hours, often with usage times the exceed that. Has anyone had similar experiences with iTunes and poor battery life, or am I doing something wrong here?
P.S. I have already calibrated my battery.

The title says it all, basically my MBP's battery drains even if the computer is plugged. When I sat at my desk to use my MBP earlier today I noticed the battery was charging. That seemed very weired, I was sure it was at 98% last night. I decided to switch my computer off and let it charge all the way up.
When I turnt on my computer again i checked the battery and everything seemed normal, but after half an hour or so I noticed that my battery status icon had chaged from charged to not charging. I loaded up Coconut battery and the battery was slightly over 90%...and it's still draining out while tipyng... The AC socket is fine and I have an HDTV connected to the same power source. Needless to say the tv is working normally... I do not have an Apple shop nearby, the closest is over 200 km (approximately 140 miles) away.

This morning I set to work on my laptop as usual. I typically leave it plugged in while not moving around, and today was no exception. I h ave a 15" macbook I purchased in December of 2010, and it's currently running OS X 10.6.8, if that makes a difference.
Anyhow, when I started up my Macbook and set to work, the battery was fully charged (indicator read that it was fully charge, and that the power source was the power adapter). The power adapter light was green. I then stood up and did some work for roughly 2 hours away from the laptop. When Ieft, I put the display to sleep - In the background the machine was still running a webbrowser (reading an all-text page) and preview (a PDF was open). This is nothing out of the oridinary, and I do it all the time usually.
What was unusual was when I returned to my machine after 2 hours of idling (with the display asleep) to find that my battery had been almost completely drained. The power adapter light was now orange, and the indicator showed that the battery was only 4% charged. The power source was still displayed as the power adapter.
I understand that during intense processses the Macbook will draw from the battery AND the power adapter - But my Macbook was simply idling! I can't fathom that a webbrowser and Preview would require THAT much draw for power. In fact, I've run my Macbook MUCH more intensely for much longer periods of time when running Final Cut and Adobe After Effects and NEVER seen this issue before.
Is this an indication of a failing battery? Ever since I noticed this, the charging time indicated has held steady at ~1:13 (that's been about a half an hour now). I don't know if the Macbook will discharge the battery completely every so often by itself, or if the battery is just failing and that's why it went from 100% to 4% in just under two hours while idle.

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".

After installing the update for Mac OS (10.7.4) my battery starts too drain too fast. As usual after 100% charge my laptop showing me time near 5 or 6 hours. Of course I understand that this number is relevant, but i always get this numbers when using not so heavy apps (Safari, Mail, Pages, Twitter and iTunes), but now i can see only 2 or 3 hours. After long searches i found the problem. My MacBook Pro 15 inch have problem with graphic-card changing, it always changes to AMD Radeon card when I start Twitter or Reader! I think that Twtitter is not so heavy app that must use diskrete grpahic-card. And because I always run Twitter in background my MacBook Pro's battery drains in a few hours.

Several weeks ago I upgraded my mother's MacBook to Lion. I had also intended to buy lion for myself but my iMac's hard drive died.Since Lion was installed the MacBook's battery life has been very, very poor - even booting up can cost 5%. A lot of people gave been discussing this. I have googled this issue and emailed Apple, but there seems to be no solution on the horizon. So I am going to reinstall Snow Leopard on the MacBook. I had intended to contact Apple to see if a refund would be possible. However, just yesterday I replaced the hard drive in my iMac and it is working fine now. So I was wondering since I paid for the Lion OS, is okay for me to install it on my iMac rather than attempt to get a refund. Is that legal? And would it work? Would the fact that it was bought using my mother's AppleID (my money though ;)) mean that if I install it on my iMac it will make my computer my morher's computer - meaning my morher's login and details will overwrite mine?

I installed the hard drive with no problem and have experienced greater performance, no clicking nor vibration, and no freezeup or rainbow wheel. I also did a clean install of Snow Leopard. I did a PRAM reset at the beginning and calibrated my battery. However, now I noticed my battery is draining FAST, only lasting 2 hours. I looked a little online and discovered I may still need to reset the SMC (shift-control-option + power key), which I will do shortly. The battery lasted 6-7 hours before with my old hdd and is at 96% capacity.

I just got a Mac Pro Octo 2.93. It has a 4870 card and 4 1tb drives. I also have a Sonnet E4P e-SATA card installed. Would a 780 Watt 1200 VA surge suppressor be enough?
The other question is about waking the computer up. My old G5 Quad (7800 GT card, E4P card, 2 500gb drives and 8gb RAM) would wake up and while the afore mentioned surge suppressor would beep, the room electrical breaker wouldn't be tripped. Using that same suppressor for the Mac Pro results in the breaker being tripped when the computer wakes up. Would getting a bigger suppressor help with this? In other words, does a unit with a bigger battery capacity allow the battery to take the extra load when the computer wakes up preventing the breaker from tripping?

My AppleCare expires on Monday September 6th, and I am wondering if my 87% capacity at 51 battery cycles suggests I should visit an Apple Store this weekend? The closest store is around 25 miles away, so if I would be wasting my time, I would rather not take the trip. My concern is mostly based on my warranty ending. This is a 2009 13" MBP.

I used an app on my MBP called Coconut battery. it said that my current battery capacity was 94% of what it was since I bought it. I assumed that means those 6% are never coming back and I should start using it more responsibly to make it last longer. I read a lot of forums on how to use your notebook effectively, when to plug it in, how much I should let it discharge etc. After 2 weeks of my new habits, I checked my battery life again and now it says 96%. Is it even possible for it to go back up?

I have MacBook Pro about 17 months old (bought new Summer 2008). According to Coconut Battery, my current battery capacity is 96% after 185 cycles (see below). This was taken just after I re-calibrated the battery last night. I usually work the laptop from the battery ... I rarely leave the laptop plugged in unless charging, and when fully charged I always unplug and run the battery down before plugging in again. So, is 96% battery capacity good or bad for a 17 month old MacBook with 185 charge cycles? Is the way I'm charging ok, or is it better to have the MacBook plugged in continuously and have less charge cycles (would this give me a better battery health %)?

So I just opened Coconut battery, and it is saying that I have 101% battery capacity. How is that even possible? In the other hand, iStat says 100%.

Got a question about the battery in my wife's white Macbook. I just downloaded (and ran for the first time) Coconut Battery and it reports the following info:
Current Battery Charge: 5281 mAh
Maximum Battery Charge: 5281 mAh
Current Battery Capacity: 5281 mAh
Original Battery Capactiy: 5020 mAh
Battery-LoadCycles: 60
Age of your Mac: 8 months
Now, I'm no rocket scientist, and I'm definitely not complaining, but how in the world does my battery have More capacity now than it did when it was new? Is this an error in Coconut? System Profiler reports the same capacity and my research online seems to concur that 5020 mAh was the original capacity.

I've got a 4 month old Macbook Aluminum 2.4 ghz. I was getting great battery life for the first couple of months. But I'm now getting 3:10 with screen half light, and wifi on, bt off, doing a bit of downloading, etc. I've recalibrated the battery a number of times. According to activity monitor my cpu is hovering under 10% when I'm doing my battery test. This is at least 2 hours less than I was originally getting. Coconut Battery tells me that the original capacity was 4100, but its currently at 4052. Battery load-cycles are at 97 and it says the Mac is 5 months old. Should I take it in to the Apple store under AppleCare?

I bought my MacBook Pro 13.3" 5 months ago (according to Coconut Battery) and the battery-loadcycle is already at 51 and 89% battery capacity. Anyway I wanted to know, if I keep my Mac plugged in on the charger will the battery-loadcycles decrease?

I get ready for the next disappointment tomorrow (maybe no MBP update) and looking out for a MBP at eBay. I've found a good one (August 2009) 2.53 GHz, 4 GB RAM, 500GB HDD etc. for round about 900� (1.200$) (in Germany we pay 1533� for this model so round about 2088$). The guy sent me a screenshot of the battery capacity which is 87% (4762mAh) after 56 loadcycles. Is that acceptable? IMO it's a bit too low - what do you think? Maybe I'm going to buy a AppleCare Protection Plan afterwards ... would the battery be covered?
