Hello,
I recently got a MacBook. I'm not disappointed with this purchase, especially since it's my first laptop and my first Mac.
The only small downside is the battery. I don't know if it's normal, but when it's charged to 100 percent, it gives me a battery life of three hours, while APPLE said it would last six hours. Moreover, the 100 percent runs out pretty quickly. I don't do much apart from MSN and email, and I check my blog or Facebook.
Sometimes, I remove the battery and leave my cable plugged in to run the Mac, but I read on the APPLE website that it's not very good either because it could damage the battery if done often, etc... Plus, I don't really like being on the Mac while the laptop is charging...
If you have any tips for making my battery last longer or if I should change it or if this is normal, please let me know.
Have a good afternoon.

Hello
I've had at least 5 MacBooks pass through my hands, all recent models. I've done tests on the battery. I agree it doesn't last 6 hours. But it doesn't last 3 hours either. It lasts a little over 4 hours with Wi-Fi on, screen brightness at half, while browsing the internet or chatting on MSN, or writing something. If we're watching a movie, then yes, it lasts about 3 hours. If we're watching a movie from a DVD, it drops a bit below 3 hours.
So, either there's a problem with your Mac, or you're not only using it to chat on MSN as you say. Oh yes, I forgot, if we turn off the Wi-Fi and lower the screen brightness to the minimum, we reach almost 5 hours.
Rest assured, even if the battery barely lasts over 3 hours, as you say, it's better than most HP or Dell laptops, which barely exceed 2 hours, 2 hours and 30 minutes for the best ones.
And for battery maintenance, you definitely shouldn't leave it plugged in all the time (as I've seen more and more people do). If you found Apple's advice on the subject, follow it to the letter.
Best regards.

Hello,
the battery life indeed depends on how the Mac is used.
Here are some factors that can explain a reduction in battery life:
- Wi-Fi on
- Bluetooth on
- Heavy access to the hard drive (file copying/downloading, etc.)
- Connection of external devices (USB hard drive, USB stick, keyboard, mouse, etc.)
- Ethernet connection and heavy traffic.
- Screen/keyboard brightness too high.

Hi everyone,
the battery of my 13-inch MacBook Pro (2009) drains when it's in sleep mode. Do you think it's because my Wi-Fi is enabled?
If so, should I disable it every time I'm not using it anymore?
Thank you for your help.

Hello,
I have the same one as you, MacBook Pro 13-inch, the battery drains in sleep mode if I don’t close it, whereas when I close it (go figure) it doesn’t wear down... weird, I don’t think the Wi-Fi has anything to do with it.
By the way, what battery life do you manage to get? Personally, when browsing the net and letting it rest sometimes, I get about 4.5 hours (Apple’s site talks about 6 hours). I’ve also switched to Leopard which is (supposedly) much less power-hungry.
My Mac has already been sent for repair, so be sure to back up well because apparently some series have an issue with the hard drive, mine was replaced a month and a half after I bought it.
Best regards.

be careful of double posts.
It depends on what you are watching during the 4 hours of internet. If you are on YouTube, it’s certain that it lasts a bit less than what Apple says on its site. YouTube uses Flash to play videos, which in turn uses the processor.
I have the same computer. On the internet, brightness at half, doing HTML (so no videos, no Facebook, no games) it lasts almost 6 hours. While doing office tasks (Pages or OpenOffice) it easily exceeds 8 hours. When watching videos on QuickTime, it lasts about 4.5-5 hours. I can comfortably watch 2 movies in a row with the same battery charge.
I’m telling you this for comparison.

I just spoke to an Apple Mac Technical Support Advisor, here’s what he told me:
No worries, the Mac can be plugged into the power supply without any issues, preferably when you're at home, even when the battery is charged but not continuously (unplug it when the Mac is not in use).
Key condition: battery calibration as recommended by the Apple site (1 to 2 times every 2 months)
Also, when purchasing a Mac, you get 90 days of free support from the technical service, after that, when the technician records your request, you'll be charged 49 Euros for the service
Small advice: do it before or take the 3-year warranty that covers all risks and services.

1. Update to the latest version of the software
2. Keep away from extreme temperatures
3. Remove certain cases during charging
4. Keep half-charged when storing long-term
5. Calibrate your battery
Calibrating your battery maximizes its potential by fully charging it first, then completely draining it, and finally fully recharging it. Apple does not recommend leaving your MacBook plugged in all the time. Additionally, Apple even recommends charging and discharging your MacBook's battery at least once a month - they even have a calendar event to remind you.
6. Restore Energy Saver.
The first step you should take to ensure that you are getting the best out of your battery is to restore the energy saver settings to their default values. Open System Preferences and select Energy Saver. Make sure the battery settings are exposed and click on Default Settings. This should turn off the Mac after 10 minutes of inactivity, the screen after two minutes, allow the hard drive to sleep when possible, and slightly dim the display when on battery. Do not enable sleep, as this consumes power even when you think your Mac is sleeping.
7. Dim all lights.
8. If all these solutions do not extend your battery life, you may need to buy a new battery. You can purchase it from here: http://www.fr-batterie.com/batteries-pour-portables-apple-batteries-c-1_28.html

Yes, the screen was using up quite a bit of energy. I lowered it and the battery is already draining much slower!!!!!
I disabled my Bluetooth!!
But I'm keeping my mouse lol because I'm on a desk so it rests my wrist!! Other than that, I'll remove it!
Wifi is always on because I go online quite a bit.
Otherwise, yes, I use MSN but I also browse web pages as mentioned earlier but nothing more than that. Just enough time to check my emails, messages, etc.
Thanks for your advice!!! I'll see how things go from here!
Have a good evening.

Hello everyone!
With all the confusion reigning on the internet, I decided to get the information straight from the source (Apple Technical Support)
I just spoke with a Mac Apple Technical Support Advisor, and here's what he told me:
No worries, the Mac can be plugged into the power source without issue, preferably when you’re at home, even when the battery is charged, but not permanently (unplug it when the Mac is not in use).
A key condition: calibrating the battery as advised by the Apple website (once or twice every two months).
Also, when purchasing a Mac, you receive 90 days of free technical support, after which, when the technician records your request, you will be charged 49 Euros for the service.
Small tip: do it beforehand or take the 3-year warranty that covers all risks and services.
I hope everything is clear now!
Here’s the explanation:
First of all, it is unnecessary to remove your battery to preserve it when you plug your laptop into the power source. Indeed, Mac OS X includes a power-saving feature that detects the charge level of your battery and stops charging when it reaches 100%. So you can use your Mac without worries, and once again, everything has been designed to simplify its use for you.
However, to prolong the life of your battery, Apple recommends calibrating it every two months. This calibration procedure is very simple but takes some time. You just need to remember to do it. The ideal is to set a date.

Hello, as you may have been told, the battery doesn't necessarily last 6 hours as Apple states; it depends on what you do, the brightness, the connections, the devices plugged in...
I would like to get an idea of your battery status, here are the instructions to access power information:
1) Click on the small apple in the top left corner of your screen
2) Click on "About This Mac"
A small window will open
3) In this small window click on the "More Info..." button
A larger window will then open
4) In this window click on Power (in the hardware sub-menu)
5) Write to us what is written (you can add it by selecting the text about Power and then copying/pasting it)
Also, Apple provides recommendations for using and preserving your battery in the best way, it's here: https://www.apple.com/fr/batteries/maximizing-performance/ (official website)
Your MacBook's battery initially has 1000 charge cycles after which your battery will have less capacity (I'm talking about autonomy...)
That's my opinion...
Goodbye and see you soon!

Hi, here’s how to calibrate your battery:
Plug in the power adapter and fully charge your PowerBook's battery until the adapter's light turns green and the menu bar indicator on the screen shows that the battery is fully charged.
Leave the fully charged battery at rest for at least two hours. You can use the computer during this time as long as the power adapter is connected.
Disconnect the power adapter without turning off the computer and run it on battery power. You can use the computer at the same time. When your battery is low, a dialog box will inform you.
At that point, save your work. Keep using your computer. When the battery is very low, the computer will automatically go into sleep mode.
Turn off the computer or leave it in sleep mode for at least five hours.
Connect the power adapter and leave it connected until the battery is fully charged again.
See you later :)

I have a 13-inch unibody MacBook, purchased in early 2009, so it's been 4 years now. It's from late 2008.
I use it morning and night, and often during the day.
Today, it shows 1607 cycles while the maximum according to Apple would be 1000, and the battery has exactly 3 hours of autonomy, less obviously than when I bought it.
I use it this way: when the charge is full, I unplug it and let it completely discharge. I only plug it back in when it approaches 0% charge.
Only Bluetooth is turned off.
Reading various sites that discuss the issue without really knowing "the" solution, it seems that my way of doing things is the right one. "Good" is indeed the term used in the "battery information" for the section titled "conditions".
I had a PBG4: by leaving it plugged in all the time, battery inserted, it had no autonomy after 2 years. Later, since it served as a desktop Mac, I ended up buying a new battery and removed it to put it back only when necessary (travel or moving). This was also a good initiative, as when the Mac was stolen during a burglary at the age of 5 (poor thing), the battery, 3 years old, was in top shape.

A MacBook Pro battery normally lasts 6 hours, but it all depends on what you're doing. Personally, when I'm on the internet and not watching videos, my battery can last over 5 hours.
When I'm just on iTunes and LibreOffice, my battery can last 7 hours!
Maybe it also depends on the type of Mac.
Side note: YouTube uses a lot of battery!
Anyway, I see that this question was asked a long time ago, so I think my answer doesn't serve much purpose, but in my opinion, your Mac has a problem if it only has 4 hours of performance.

Just unplug the computer if you're not using it. Maybe get a larger capacity battery. Also, use your computer plugged in.
