Battery calibration recommended by Apple, why no utility?

Like virtually all mobile computer manufacturers, Apple recommends that users calibrate their laptop batteries every few months, as Scott pointed out a couple of years ago. Unlike many manufacturers, however, Apple does not include a utility to automatically perform a calibration. Given Apple's uncanny ability to make things user-friendly, this seems like a bit of a glaring oversight. What are the benefits of calibration? Primarily the goal is to ensure that the microprocessor in your battery provides an accurate estimate of how much time you have left on the battery. Over time it can lose track of just how much juice your battery has in it, and calibration gives it a very accurate reading on the battery's health. Older battery technologies also benefited from a process called conditioning, which was typically performed the same way as a current battery's calibration process. In a nutshell, you fully charge the battery, fully discharge it, then fully charge it again. It's unclear whether modern lithium batteries gain anything in an actual capacity perspective from this process, or if it is simply a calibration of the microprocessor for the purpose of providing accurate time estimates.Continue reading Battery calibration recommended by Apple, why no utility?Read | Permalink | Email this | Comments

TUAW Review: Richard | Solo Smart Backup Battery for iPhone / iPod

If there's anything I've learned about the iPhone 3G since July 11th, it's that the battery life is horrible. If I'm just texting and making the occasional call, I can survive for a day, but if I try to play games or use 3G I know it's going to go to the dreaded red battery icon quickly.That's why there are a growing number of manufacturers who have extended battery packs for the iPhone on the market. For example, I looked at the Kensington Mini Battery Pack and Charger (US$49.99), but the website doesn't show that it works with the iPhone 3G. My next choice was the Richard | Solo Smart Backup Battery. This US$49.95 lithium-ion battery pack has saved me from running out of juice prematurely more than once! Read on for more information about this must-have sidekick for the iPhone 3G.Continue reading TUAW Review: Richard | Solo Smart Backup Battery for iPhone / iPodRead | Permalink | Email this | Comments

Exchanges begin on October 10, both online and in person at Apple retail stores.
