One of the most common complaints about Apple’s mobile products is their length of battery life. Whether someone is using an iPhone, iPod Touch, iPad, or a laptop such as MacBook Pro or MacBook Air, the battery life is one thing most users will say is problematic.

The first thing to realize is that a device’s battery is largely determined by its usage. For example… An iPhone that is generally used to check email will have a longer battery life than an iPhone that is more commonly used to shoot video. So when deciding if your device is having battery trouble, first ask yourself about your usage.

If you still believe your mobile device to have a problematic battery, one option is to recalibrate it.

Step One: Use the device until the battery has drained to the point of self-shutdown. Basically, use it until it turns itself off.

Step Two: Recharge the battery without any interruptions until it is fully charged to 100%.

Step Three: For mobile devices such as iPhones, iPads, or iPod Touches, reset the device by holding the Sleep/Wake button at the top and the Home button at the bottom until you see the Apple logo then release. You can ignore the “Swipe to Power Off” option.

For laptop Macs, there’s no need to reset the device but you can choose to restart it if you’d like. The main thing to remember is that the electrons in your lithium-based battery need to move occasionally so leaving it plugged in all the time is not the best thing for your notebook computer. Please keep in mind that current laptop Macs don’t need to be calibrated. More info here.

When it comes to how frequently you should perform this maintenance, every few months is just fine. It’s also good to know that you won’t see any more of an increase in performance by calibrating more than once a month. Just keep an eye out for software updates that frequently improve your battery even more than using this tip. If after you’ve calibrated your battery, you still feel that your battery drains quickly, it’s worth it to pay a visit to your local Apple Store to have it looked at.

If after all this, you still find that your battery isn’t lasting as long as you need it to, you can always purchase an external battery pack such as this one to keep with you in case you need it. is here to serve as an reference archive for older articles until 2015 but will no longer be active as I take paternity leave.
