I told you the other day that the new iPad continues to charge after the iOS it indicates that the battery is 100% charged and that the device continues to receive power through the power supply for another hour after the iOS says that it is finished. The information came from DisplayMate which meanwhile updated them and now it tells us that in reality the tablet takes power from the power supply for another two hours and 10 minutes after the iOS says that it is already charged. The measurements were made by connecting a device to the cable that powers the tablet and which measures the level of energy taken from the power supply during charging.
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 the screen that it was fully charged. Other tablets and smartphones also lie about their charging status. 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.
In practice, iOS "lies" when it tells you that your terminal is 100% charged, and here the culprit is the system that calculates the battery charge level. Those from DisplayMate claim that this system works based on a mathematical model that would calculate charge/discharge rates based on recent battery discharges and estimate the current charge level. It is not the first time that we hear that this iOS system has problems, but it seems that the rest of the tablets have exactly the same problem, so we should not blame only those from Apple.
In conclusion, if you want a 100% charged battery, it would be better to leave your tablet charging even after iOS tells you that it is 100% charged.
