MacBook Pro :: Calibrating My Battery Every Day Good Or Bad?
May 10, 2010
I just read how to calibrate your battery, and I found out that I've been calibrating my new MBP 13" battery pretty much every day (unintended). I've been using it quite heavily since I got it last week... charging it fully, and reconnecting it to the charger whenever the battery hits somewhere around 10%.. Is this good or bad ? Should I charge it whenever it hits 50% instead ?
Apple says we are supposed to calibrate it once a month. Is it bad if you do it more often ? Any thoughts on this ?

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?

I calibrated my battery last week and I'm pretty sure I'm getting worse battery life after the fact. Has anyone had this experience? Can battery calibration hurt your battery?

I've done everything correctly that the apple described 'bout calibrating and its not lasting even 2 hrs. All I do is surfing. I have the brightness just one block. No keyboard illuminate. Bluetooth is off and for me to get 'round 2 hrs. I gotta keep closing the macbook's screen.

What effect will the macbook have, if i fully charge and discharge the battery on a daily basis. I will leave it running on battery power when i leave for the day, and let the battery drain/discharge fully through the night.I will hook it back up in the morning to have it fully charged, may be 30 - 60 mins after it being fully charged, i will pull the power out and run the laptop the whole day on battery.

Point 4. Says the computer will automatically go to sleep and then point 5. Says I should turn of the computer. Isn't it the same of the computer stays in the sleep mode?

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.

I want to calibrate my battery -- is there a recommended app for just chewing away to make the process faster? Do people just play movies over and over again?

Any info or links to the one you guys bought would be awesome. Also, is the original battery a 4600mAh or a 5200mAh? Ive seen both listed as the same a1281 battery.

Im a little confused, is the Air Battery life that good? I've taken the following claims from the Apple website. MacBook Air - Get up to 5 hours of battery life on a single charge on the 11-inch model and up to 7 hours on the 13-inch model. 13" MacBook Pro - The new energy-efficient architecture in the 13-inch MacBook Pro gives you up to 10 hours of battery life on a single charge. I understand that Steve Jobs advised that they were using a better way to measure battery life for the Air that reflect real world usage better (WiFi Browsing I think?) so how does this compare to the MBP range? I guess the MBP battery claims were made using another older method, so any thoughts on how the Air's battery life compares to other PC's and Mac's?

I am looking to buy a replacement battery for my 17inch Macbook Pro. It has become a victim of the swollen battery and I have had no luck with getting a swap, since the program closed. Anyone know of a good site?
Also on a side note, I noticed since I removed my battery HD videos on youtube and my HDD. Kinda lag now. I just put the battery back in briefly and the programs gone away. What is that about?

I have a 3 1/2 year old Macbook, my Applecare has ran out. About six months ago my computer began shutting off immediately when unplugged. (Was letting my roomates use the computer, came home one day and it started doing this.) I believe that my battery is OK, it performs between 97% and 99% consistently. When I do the battery test, all of the lights light up.
I've read through the forums and it seems a lot of people are having this problem, but their batteries are bad. What are some options/solutions to this problem? I am willing to invest money wisely into the computer to keep it running smoothly for a while.

I've never full drained the battery below "50%" 61 times so I don't know why it says I've had 61 cycles. I always leave my laptop attached to the AC adapter. Is 61 Cycles with 99% battery life good for a 5 month old laptop?

My Apple remote won't pair with my iMac (Lion) or my MacBook Pro (Snow Leopard). It works with iTunes and VLC Media Player on both without being paired, but pairing is supposed to work isn't it?I've used the iMac's camera to check that the remote's battery is OK. When I press any one button, the live camera picture shows a blinking light. However, if I press two buttons (Menu and Next, as is required for pairing) there is no blinking light.Is it possible that the Apple remote's battery is good enough to create a blinking light when one button is pressed, but not when two are pressed? I've hardly used it, so I'd be surprised if the battery was low already.
Also, I'm not sure that when I click on Pair... in System Preferences > Security & Privacy, whether the pressing of two buttons for pairing has to be done while the OK popup is present or not. It doesn't matter when I try it, I never see a paired-remote graphic.

i've had my macbook for a little under a year and i think i may have shortened my battery power. i have a tendency to leave my laptop plugged in long past the fully charged time and allow it to run through the battery till it shuts down. i do this when i accidentally fall asleep listening to music or leave for work and forget it's on or plugged in. how hard on the battery or laptop is it to do this repeatedly? when it's fully charged it tells me i have roughly 4 hours of battery power available. is that the right amount? is there anything i should do to protect the battery? the manufacturer warranty will be up in march, should i take it in for a check up while i may have the option of not having to pay for it?

I just got my macbook week ago. i noticed that the menu bar had a slight pink color on the right side. i went on the apply website and read on calibrating the display but it still has pink lines. anyone has the same issue. also does it matter if we calibrate the display or not. and finally, i read on some site that we supposed to calibrate it in the dark, which i did not do. is that the reason i am still seeing pink color.

i am about to have my first mac, a macbook pro. I live in Turkey and Apple prices are really of the roof here. So i ordered it from Amazon to save 1500$ and had it shipped to my friend's house in USA. He will bring it with him when coming here to Turkey. I ordered on 16th of June, delivered on 23th of June and i will be getting it tomorrow. Problem is i heard that it should be calibrated within a week after buying. I suppose this wouldn't be a problem right? I mean it should be a week after booting it i think?second question is about using while calibrating. I know i can use my laptop when it is fully charged and resting on that state for 2 hours but can i use it while it's charging.

I usually use my 2209WA connected to my Desktop running Windows 7, but sometimes I'll connect it to my MBP. Windows seems to have found a color profile that works very well, which it got from Windows Update, created by Dell, presumably.It might not be good enough for someone who needs 100% accurate color, but it's good enough for me.
I tried two different profiles for this monitor connected to my MBP. The first was one I downloaded from a forum somewhere, and the second was the one Windows is using, copied over. The display looks OK with both, but the color depth isn't nearly as good as it is on Windows. Connected to my MBP, the colors look washed out and flat, while the same colors are much richer when the monitor is connected to my PC. For example, pure blue (#0000FF) looks faded when the monitor is on my MBP, and much deeper when it is on my PC. I tried changing the gamma setting under OS X (manual calibration), but it didn't have much effect. It is set at 2.2 for both 2209 profiles and for my MBP LCD's profile.
How can I make my monitor properly calibrated when it is hooked up to my Mac?
In both cases I am connecting the monitor with DVI (just moving the cable since I'm too cheap to buy a switch), and both OSes have it set at native resolution. The settings on the monitor (color, brightness, contrast, etc) do not change when I switch computers.

I recently purchased a HP 2009m glossy 20" monitor. I have a late 2008 model macbook pro (glossy). I have been having a hard time getting the colors and whites to look exactly the same. I have tried calibrating the display over and over but the whites never look exactly the same even though the default white points are the same for both the macbook pro/hp displays. Any hints outside of getting a sensor/external program?

i have recently spent several evenings re-calibrating my Dell U2711 display and have finally come up with a fantastic image so I thought I'd share my results for those having trouble calibrating this display (given the low quality AG coating this display comes with, calibration can be quite tough). Plus, during my Google search, trying to find some calibration tips, I was surprised at how little I found. Most of the forums I went to are discussions about the AG coating with hardly any talk about calibration. So, because of that, I figured I should share my calibration steps.
I edit video so I managed to come up with a calibration that shows great shadow detail (without crushing the blacks) yet still gives a deep, rich look for the graphics as well. Everything from the highs to the lows look great! And parts of the screen such as the dock look so vivid it's hard to distinguish from an Apple Display in terms of richness and clarity (without the shine, of course). You can still see the grain of the AG coating on bright areas of the screen but it's hardly distracting at all. On a side note: this is a great display for editing video even with the AG coating but if you edit still photography I would stay away from the U2711 entirely: still image + still grain = disaster!
Unfortunately I don't know much about internal computer system settings or if all displays that Dell ships are identical, so I can't say for sure that the calibration I did will work for everyone. However, if all Dell Displays and Apple computers (I use a 2010 MacPro) are 100% identical when shipped, then, if you follow my steps exactly, you should be able to come up with something similar to what I got. But I can't say for sure:
Step 1: Setting up the display.
Set the contrast to 100% and the brightness to 80%. Set the Gamma to (Mac), the Mode Selection to (Graphics), and the Preset Mode to (Custom Color). Now, in custom color leave the green at 100% and set both the Red and Blue to 98%.
Step 2: Setting up the Mac.
Run your Mac's Display Calibration Assistant (located in the Display section of System Preferences). Select the checkbox for Expert Mode and keep clicking continue till you get to the section with the lined boxes with the Apple logo in the middle.
Now, for all 5 'lined box' steps, make the Apple logo disappear using only the left slider (do not touch the right slider at all). To make the Apple logo disappear (blend into the box) you must squint your eyes until the lines that make up the box itself become one solid color (my eyes were about 75% closed). Take your time and make sure you are confident that the Logo is gone.
Then, when you come to the gamma screen either select 2.2 or 2.15 - the proper setting should be 2.2, however, I found the blacks to be not as deep as I'd like them to be (most likely because of the AG coating) so I choose 2.15 which I found to be the key to giving the display the richness it needs to look great.
When you get to the 'Target White Point' screen, select the checkbox 'use native white point'.
Then save you calibration profile and exit the assistant. Now go back to your Dell display settings and set the brightness to 100% and you should be good to go! Note: if you find your screen to be a little too dark, re-calibrate but try selecting 70% or 60% for the brightness during step one. That way, when you raise the brightness to 100% at the end, it should be somewhat brighter.
I hope this works as great for you as it did me! And even if it doesn't, hopefully you will end up with something half decent. But either way, please do share your results - I know there are a lot of people out there struggling with this display because of it's AG coating and some are even attempting to remove the AG coating with bad results. I even considered removing mine but now I am glad I didn't take the risk (I suck at doing those type of mods, haha). Now, my display looks almost as good as an Apple display (and without any glare!

I recently got the Dell U2410 and I felt like out of the box the color and everything was way off, and certainly no where near matching how things looked on my MBP screen. I went through the little calibration process in the system preferences (with the advanced options) and it's somewhat better (I don't think the gamma was at 2.2 before), but it still doesn't seem so great. The brights look kind of blown out, the shadows are a bit too black, and some of the colors look off. Also, if I look at a solid color I can see moving lines (almost like a much more mild version of when you record a computer screen with a camera running at a different refresh rate).
Did I get a crappy one, or do I need to do something different? I had heard so many good things about this monitor and now I'm considering returning it for a 24" ACD.

My machine: 17" 2.33ghz mbp.After installing Snow Leopard, when trying to calibrate the screen it gets to the end and then reverts back to the ****** default snow leopard calibration and says: "An error occured. The new calibrated display profile could not be created or set to be the current profile for this display."also, i noticed they spelled "occured" wrong. It should be "occurred" no?any of you guys have this issue? and if so, how do we fix it?

I have just completed rescuing a water damaged MB C2D which was originally a 2.16 and is now a 1.83. Fun project for a cold Sunday afternoon. 5 hrs I have one issue with the MB and that is the charging of the battery. The battery icon sometimes shows 'no battery' or if it shows a battery is recognized, it isn't charging. The LED on the mag-safe charger is always green. The battery is from the water damaged 2.16 and my thinking is that it may have suffered damage from being exposed to water. Original owner left the MB in the backyard and it started to rain!

My battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.
