MacBook Pro :: Charge Techniques And Usage To Preserve Battery Life?

Aug 8, 2009

I have been reading posts about charge techniques and usage to preserve the battery life but its often inconclusive and comes with different opinion. Even Apple do not have a proper usage/charge guide to maintain battery lifespan. Therefore, I have decided to conduct this study and perhaps produce a certain conclusion on what is the best charge technique to maintain the battery life of our Macs. Please fill in the following template and a final conclusion will be produced once we've received enough inputs. Use software like Coconut Battery to retrieve the relevant information required by this study.

MacBook Pro :: Charge It Or Let Battery Drain During Normal Usage?

Aug 20, 2010

Is it better, during normal usage, for example at home, where you could either charge your MacBook Pro or let the battery drain until it is used up (5%, ...).

Some people say that letting the battery cycle is the best option, yet other people, including my friend who had lost many many cycles even though he had attempted precautions (Dim screen brightness until one block remained, wireless off, bluetooth off) had said that having your laptop plugged in as muchas possible is the best option, as there would be no cycle change.

MacBook Pro :: Battery Life Test - Keeping Track Of Usage Manually?

Jul 9, 2009

I just got a new MBP and I want to test how much battery life I am getting. Is there a way to do this other than just manually keeping track of how much time I used it for? A program or something that tracks it for me?

MacBook :: 91% Battery Life After 30 Charge Cycles?

Mar 18, 2010

I noticed that my MacBook doesn't run as long as it used to before I have to charge it again. I downloaded CoconutBattery, and it tells me that my battery is down to 91% of its original capacity after only 30 charge cycles. It's 5 months old according to CB, and I bought it new on Dec. 24th. (It's a Unibody White...) Is this normal, or should I take it into the Apple Store for a replacement?

MacBook Pro :: Short Battery Life For Unibody Battery'

MacBook Pro :: Battery Life Slightly Shorter After Calibrating Battery

May 4, 2012

I calibrated my MacBook Pro battery and then noticed that the battery life seemed slightly shorter after that. I calibrated it according to this: [URL]

Just wondering if I have done anything wrong...  

One more question... What do they mean by "At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep." Does it mean that I have to use the computer until it just shuts down or should I shut it down once the "Low Battery" warning pops up?

MacBook Pro :: Battery Getting Hot / Battery Life Reducing

Aug 10, 2009

I've had this MBP for just over 8 months now, I'd intially purchased one in november, but the audio out used to give a crackle sound so they replaced the laptop. Moving on to the point - in the last week or so, I've noticed the MBP suddenly seems to get very hot and the fans turn on and thus suddenly becomes very noisy. I was using it on the bed so could appreciate that I may have been blocking the vents, but I've had it on a stand the past couple of days and it still seems to do it for no particular reason. The charger usually always gets ridiculously hot, but the MBP used to stay relatively cool, now the MBP gets hot independently of whether its being charged or not. Moreover, my battery life has gone from what used to last 4 hours, to around 2.25.

Cocunut battery gave the following stats:
Current Battery capacity: 4483mAh
Load Cycles: 222
Age: 8 months

MacBook Pro :: Late 2008 15 Battery Life - Watching Movie From Hard Disk Use Less Battery Than DVD?

Nov 11, 2009

i just ordered a late 2008 macbook pro 15 with the dual GPUs (9400m and 9600m GT) and I'm a little worried about the battery life.

-What can I expect if just doing normal every day stuff (web surfing mostly?)

-does watching a movie off of the hard disk use less battery than watching it off a DVD? Is there a big difference?

I'm not a big gamer but would like to have the horsepower to play a game should one come out that I want. I'm also not a big traveler so battery times are only of average importance.

Basically, I'm asking if I made a good purchase considering I have only average concerns for both battery and game performance. They had the new 7 hour battery 15" macbook pro for the same price but it doesn't have the dual GPUs.

MacBook Pro :: Unable To Charge Complete Battery / Service The Battery?

Nov 15, 2010

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.

MacBook Pro :: Unable To Charge Battery / Charging Stucks At 99 Percent With Service Battery

Aug 20, 2010

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?

MacBook Pro :: Wants To Know About Battery Life

Jul 18, 2009

I have a quick question about the battery in early 2008 MBP. The laptop is 13 months old, with 273 load cycles, and it is already down to 72% of original capacity. I've read that it should still have 80% at 300 cycles. Is this normal, or is the battery dying faster than it should? I don't suppose there's anything I can do short of buying a new battery right??

MacBook Pro :: To Know About Temperature And Battery Life ?

Sep 4, 2009

I have a late 2008 15" macbook pro, 2.8ghz. Since I got it, it's been running fairly hot at times. It's summer right now and pretty warm here, but it's idling at about 67 degrees. I've seen it get a lot higher, up to around 85. Is this normal? Does it need a trip into the apple store?

My other problem is battery life. I'm only getting about 2.5 - 3.5 hours with the lower end video card, just using safari, and I don't know if that's normal or not.

OS X :: MacBook Pro With Only 3 To 5 Hours Battery Life

Sep 30, 2009

I have the 13" MacBook Pro with the beefiest processor and a 500GB HDD. When I bought the machine, I quizzed the guy at the store about a couple of things. In particular I asked about the battery life. He told me apple claims that this machine should have 7 hours of battery life when doing light tasks, but that he personally was able to squeeze out over 8 hours of battery life with simple web browsing.

My problem is that I can barely get 3,5 hours worth of batterylife out of the machine before it gives up the ghost. And this is with the backlight on the display turned down to 1/3 of full brightness. And all I'm doing is browsing text webpages with no flash. Is this normal? Or have I simply overlooked some basic power option that I need to toggle?

MacBook Pro :: How Do Increase Battery Life

Apr 19, 2010

I have a question with regards to behavior that can either extend or diminish the overall life of a laptop battery. My friend recently purchased a new laptop (sony vaio) at a local Microcenter. The salesman was very insistent upon lecturing my friend as to the proper way to take care of a laptop. One of things he mentioned was to never move the computer while it is on, and to always close the lid before engaging in any sort of extensive moving (due to hard drive? processor? any verification on this?). Another thing that was very insistent upon was to always let the battery deplete from full to near empty on every charging cycle, and only charge the computer when replenishing it back to full. He claimed that this would dramatically increase the overall life of the battery.

My specific question relates to the MBP and this battery concept.

1) In general, can anyone verify this / does anyone believe that it would make a significant difference?

2) I remember watching one of those apple videos on the apple website where they were talking about their new battery technology, and they mentioned something about a chip that regulates the power distribution to the battery cells, thus preventing over charging, or something along those lines. Would this negate the advice given by the friendy salesman at Microcenter?

MacBook Pro :: Battery Life After Replacement?

May 16, 2012

I have a MBP supplied in Feb 2011, something was not quite right with the keyboard so they replaced the top case.  I went to upgrade the ram and noted that the battery was damaged, they broke one of the plastic pieces that the screw goes into to hold the battery.  At the same time the top case that they repalced discoloured. I mentioned both things and apple replaced the top case and the battery.  While after some use the top case looks fine I can't say the same for the battery.  It seems not to last as long, while happy to monitot it for a short while I wanted to check if anything should be done when replacing the battery?  Does the MBP need to be told it has a new battery?

MacBook Pro :: Best Way To Optimize Battery Life

May 31, 2012

so since my late 2010 Macbook Pro died I just got a new one this weekend. I was wondering what the best way to optimize the battery life on it would be as I'm noticing the battery life seems shorter on it than the new one. Is it true that if you use your Macbook more often on the AC charger than just on the battery itself it will make the battery life better in the long run?

MacBook Pro :: Very Poor Battery Life?

Jun 2, 2012

I know this has been asked many times before but seeing as im a new mac user ill ask anyways. I bought my Macbook pro 13" i5 yesterday and have noticed the very poor battery life. A partial reason i bought a mac was because of the long battery life advertised. My battery is lasting 3 hours off charge ( the same as my 3 year old eePc) I have called support but unfortunately being a Sunday no one is available to chat. Lets see my chances on here.What can I do to make my battery life last longer than 3 hours!?It the battery drains even when im just browsing the net with no other applications open... as im writing this it has already drained from 59%-50% within a 10 minute time span..

MacBook Pro :: How To Check Battery (life)

Jun 13, 2012

I bought a 2009/2010 MBP a couple of years ago (still have AppleCare on it) and the battery life on this machine has been absolutely atrocious. I feel like I unplug it from my desktop and sit down on the couch and thirty to forty minutes of web surfing and i am down to 25%. and i have to plug in or I will get a warning that i am under 5% in another 10 minutes.Does anyone know if this is partially or fully due to Parallels? I just checked and with not much running all i see is a prl>vm_app that is taking up 12.6% CPU.

I mean I hesitate to ask this because I ran a test about six months ago by fully charging it and turning it on (no apps running) and my recollection was that it went into deep sleep in about three hours. This was when it was doing nothing.Any facts to measure this against or any way to do an actual analysis on my end? The cats at the genius bar are always like "situation normal" which makes me think there is something wrong with this class of machines or something.

MacBook Pro :: New Battery Not Getting Charge

Mar 1, 2010

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.

MacBook Pro :: How To Charge Battery

Jun 1, 2010

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?

MacBook :: Good Battery & Terrible Battery Life?

Jul 16, 2009

I have a 13" 2.4 GHZ white macbook that I bought in march of 2008. About 4 months ago I all of the sudden started having problems with battery life. It was very abrupt. I used to be able to take my macbook and sit through 3 classes or more with no trouble in regards to batter life. Then suddenly the battery would drain within a few hours. It has remained that way since.

I've spent the last month or so looking around forums and other places to try and find someone with a similar problem and possible solutions. As a result I've discovered that my situation seams to be somewhat unique.

Using cocoanut battery I tested my battery's capacity and it remains at a solid 98%. How can my battery still be at 98% capacity and have such a short battery life? I also seam to be losing charge while my macbook is closed. How and why does that happen? If I leave my macbook closed for a day or two it can lose up to 25% charge just sitting there!

I've tried loads of things including turning off unnecessary things such as sharing and bluetooth and calibrating my battery, all with no avail.

What is going on?? My battery is too old to be eligable for a recal and I'm not paying $30 just to have a phone conversation with a "Genius". If anyone has any idea what's going on and any possible advice, I would greatly appreciate it.

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?

I got my MacBook Pro on the 1st of September and I'm a bit worried about the battery life. At the moment the screen brightness is one bar and bluetooth is off, which is how I normally have it and the battery life time estimate keeps changing quite a lot. 5 minutes ago it said 5:11 left, and since then it's changed to 7:30, 7:58 and now it's saying 6:50 and is now on 95% and 8:03. I'm not doing anything differently and I don't know why it's doing this.
