After several reports that the new iPad incorrectly informs the user when the battery is fully charged, Apple yesterday issued a statement. According to Apple, it is true that the battery indicator shows 100 percent when the charge in fact only has reached 90 percent.
Apple’s marketing manager, Michael Tchao says to All Things D that all iOS devices, including the new iPad, shows that the battery is fully charged, when in reality it only reached about 90 percent. The battery still continues to charge until it reach 100 percent charge.
The reason for this is according to Michael Tchao that at the end of a charging cycle, the battery can be pulled out if the phone is turned on and then be used for wireless networking and other services. The charge can go up and down slightly, but to avoid confusion among customers, Apple has chosen to show that the charge has reached 100 percent, even if it has not.
He also denies reports that the battery in the iPad can be damaged if users keep charging after it has reached full charge.
“That circuitry is designed so you can keep your device plugged in as long as you would like,” Tchao said. “It’s a great feature that’s always been in iOS”.
According to display expert Raymond Soneira on Sonera Technologies, who discovered the problem with the battery indicator, Apple has failed.
“My essential point is simply that if the new iPad is fully charged overnight then my tests show it will run 11.6 hours, which is 1.2 hours longer than if it just charged to 100% (10.4 hours). This will matter to some users,” Soneira continued. “If the iPad has cell and WiFi and background tasks running then I agree with Apple that it will cycle down and up. My lab tests were in Airplane Mode so that did not happen and I measured the true battery state.” , says Raymond Soneira.
So there you have it, more than you ever wanted to know about battery life. Now if only someone would just hurry up with batteries that last longer.
