After claims that the new iPad’s battery meter has been deceiving users into believing their device is fully charged when it is not, Apple has stepped up and explained that the behaviour is actually a battery-saving feature.
Last week DisplayMate’s Ron Soneira discovered that the iPad’s battery continues charging after the device reports that it is fully charged. Many users and websites were quick to speculate the reasoning for this, ranging from Apple’s inability to take an accurate reading to claims of dishonesty regarding charge times from Apple themselves.
In a statement to AllThingsD, Apple’s Vice President Michael Tchao explained: “That circuitry is designed so you can keep your device plugged in as long as you would like. It’s a great feature that’s always been in iOS”.
Tchao’s statement confirms that existing iPhones and iPods are designed to do the same in order to safeguard battery life in the long-run. This is due to the fact that the lithium-ion batteries found in modern rechargeable devices don’t take kindly to trickle-charging, which reduces the cell’s overall life span.
Instead these devices charge to 100%, decharge for a short while and are then charged back up to 100%. This pattern continues for as long as the iPad, iPhone or iPod Touch is plugged in.
Despite selling millions of units and receiving glowing reviews, the new iPad has made the wrong kind of headlines recently due to heat concerns and user reports that older smart covers are incompatible.
