MacBook Pro :: Battery Capacity - Not Lasting Long

Feb 21, 2010

I have noticed that lately, my MBP Mid-2009 battery isn't lasting as long on a single charge as it used to. So, I downloaded and ran coconut Battery (attached results). After 152 Charges - I'm getting 90% battery capacity. Is there a way I can improve on that. Or, is this number about right for the age of the MacBook Pro?

MacBook :: Battery No Longer Holds Long Charge / Worth Pursuing A Replacement Battery?

Jun 2, 2009

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?

Mac Pro :: Unit With A Bigger Battery Capacity Allow Battery To Take Extra Load

Apr 13, 2009

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?

MacBook Pro :: Battery Capacity 87% After 51 Cycles

Sep 3, 2010

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.

MacBook Pro :: Can Battery Capacity Increase From What It Was?

Sep 22, 2010

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?

MacBook Pro :: Current Battery Capacity 96%

Oct 20, 2010

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 %)?

MacBook :: Battery With More Capacity After 8 Months Use?

Apr 4, 2009

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.

MacBook :: Battery Capacity Only 3 Hours

May 4, 2009

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?

MacBook Pro :: 87% Battery Capacity After 56 Cycles?

Mar 1, 2010

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?

MacBook Pro :: Why Battery Capacity Too Low (33 Percent)

May 7, 2010

I've had my Macbook Pro for just over 2 years and recently bought one of the 2010 models. I'm about to sell my old one but when I downloaded Coconut Battery, I saw that my battery holds a lot less charge than it did when it was new: Have I been doing something wrong or is it just low because the laptop is 2 years old? If it's something I've been doing, I don't want to make the same mistake with my new one.

MacBook Air :: Battery Capacity - Unfavorable Results

Nov 16, 2008

Please post your battery capacity on your Gen 2 Air. Just received mine on Thursday. I have the following unfavorable results.
Capacity: 4789 mAh
94% Life
Original Capacity 5090 mAh
Battery loadcycles 11
Age of my Mac 2 Weeks....
Am I correct in assuming that my capacity should be around 5200 mAh and that this is indeed a defective battery? Please share with me if I am incorrect, as web browsing after a full recycle is about 2.25 hours, without doing anything else.

MacBook :: Solution To Increase Battery Capacity?

Jul 18, 2009

As in thread, I noticed in CoconutBattery and in iStatNano widget that my battery is losing capacity, yesterday I had 96% now I see 94%, I've got my MacBook since May and it has 59 cycles yet.

I think that it shouldn't lose capacity now, ok, later but now is to fast, do you think so? Is there any solution to increase this capacity? I've got MB Unibody 2GHz, Late 2008, but I bought it in May 2009 "as new"..

MacBook :: Battery Capacity Dropped 5% In Two Days?

Nov 18, 2009

I bought a MacBook in late October, and it was my first, so I'm pretty new to Macs. Love it so far!

But anyway, here's my question -- my battery capacity has been at over 100% since I bought it, according to coconutBattery, and yesterday it dropped to 98%. I decided to calibrate it because I hadn't done that yet. So I let it put itself to sleep and left it that way overnight, then recharged this morning. When I first plugged it in, the capacity was at 99%. Now a few hours later, it's at 95%.

So, is it more likely that my capacity has been 95% for awhile and the calibration just helped synchronize the capacity display with the actual capacity, or did I really lose 5% in two days?!

I'm trying not to be totally crazy obsessive about this, but I really need a good battery life, and I want to keep this one going for as long as possible.
