iPad Battery Level Reportedly Inaccurate

March 23, 2012

Although well-received by the public in terms of sales, it appears that the new iPad is having its fair share of problems. First there was the reported issues with overheating, then reported cases of discoloration of the screen, and then an issue with Wi-Fi reception. And here’s one more to add to the growing list of complaints: an inaccurate battery level and considerably longer charge time for the new iPad.

Reports have come in online from users that the iPad isn’t really fully charged when the iPad battery level hits 100%. Instead the iPad battery seemingly continues to charge well after the 100% marker is displayed on screen. Not only that, but the new battery also does not last as long as the iPad 2, with a reported run time of just 5.8 hours as compared with 7.2 hours for the iPad 2. Bare in mind that this is when the brightness is at the highest level, and that when the iPad and iPad 2 are set at medium brightness, the battery life is roughly the same between the two devices.


According to DisplayMate, who took the time test the iPad extensively, the iPad’s false battery level problems might be caused by an issue with a mathematical charge rate model. DisplayMate President Dr. Raymond Soneira is quoted as saying that, “The charge indicator on all mobile devices is based on a mathematical model of the charge rates, discharge rates, and recent discharge history of the battery. It uses this information to estimate how much running time is left.”

Additionally, Soneira found that the iPad, when tested, continued to draw 10 watts of electricity for roughly two hours after the device was supposed to have been fully charged. That’s a pretty big deal as it indicates that the iPad requires more time to charge than any of the previous iPads, and this may be seen as a huge inconvenience for users.

Just as with the other reported iPad problems, Apple hasn’t come out with any sort of statement regarding the battery level issue. Though if it comes down to being a simple problem with the iOS software on the iPad, we’re inclined to believe that they will ready a fix for the issue ASAP.

A few weeks ago my iPhone 4 had a problem and it would turn its self on constantly at a estimated rate of off once every 2 minutes( not counting turning on time) it would stop this for a few hours with battery percentage the same 24/7 charging or not. But still turn off, then when 1% came back on, and restart full process, could the new iPads have a simmular problem as my iPhone 4 had. The problem stopped happily for no reason last week.

Hi Curtis,

By chance, did you download iOS 5.1? We've heard that the iOS 5.1 update fixes many iPhone 4 and 4S battery issues.
