New iPad Charges Up to 2 Hours After 100%

We all know about the increased battery capacity on the new iPad due to its Retina Display; we also know that it cannot charge under heavy processing and that it heats up a tad more than its predecessor.

New findings by Dr. Rayond M. Soneira from DisplayMate shed light on another battery-related issue: based on his tests, the new iPad doesn't reach full charge when the 100% icon is shown, in fact, it takes up to an extra hour or two to do so before charging stops. The problem lies with an inaccurate battery-charge display algorithm, he elaborates.

DisplayMate - 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. ... So there is something wrong with the battery charge mathematical model on the iPad.

At 2:00 hours after reporting 100% charge the new iPad hardware started to reduce the charging power. At 2:10 the recharging cycle fully terminated with a sharp decrease in power.

The new iPad battery is truly fully recharged 2 hours and 10 minutes after prematurely reporting on screen that it was fully charged.

Owners of the new iPad who want to make full use of their gadgets might want to rethink their charging habits by waiting up to an hour after the device flashes a 100% badge.
