Battery technology is considered slow to progress if compared with the development of phone technology, so that the speed of battery depletion is almost the main problem and the common denominator among all users of smart devices of various kinds, and we find that phones are smaller in size, but batteries increase in size and companies try in various ways to stop this bleeding in batteries and that. By creating new types of screens with less energy consumption. Upon the release of the new iPad, a large number of specialized centers studied its battery in order to contain two major energy-consuming features, namely the retina screen and the fourth generation services, and the results were good, as it was proven that the new iPad battery lasts for a period approximately equal to the same period of time as its predecessor, the iPad 2, but they They found surprising that the iPad continues to charge even after reaching 100%, so why does this matter?

Dr. Raymond, a technology specialist, connected his iPad to electricity to be charged until it reached 100%, then he used it until the charging was over and recorded the time period and found it 10.4 hours, then he plugged it back in the charger and skipped the charge of 100% (virtual) He waited for the charging to stop and used it (the same as the previous use) and found the new time period of 11.6 hours, and Dr. Raymond thought that this is considered a malfunction of the iPad, but Apple has explained why this happened, but before explaining Apple's explanation, let's first clarify some important points about the batteries .

How does Apple measure the amount of charge?

The first information that should be known is that estimating the battery charge is not as easy as expected, it is not like a car, by looking at an indicator, you can know precisely how full the tank is with fuel ... According to Isidor Buchmann, a specialist in the field of electronics, there is no accurate way to tell you the level of the battery at a specific time Rather, the number that appears is an approximate number, so the specialists calculate the amount of electricity that the device gets to calculate the amount of charge, so the more the device is charged, the more electricity it gets. For example, with regard to the new iPad, when it is recorded that it is charging at 4.2 volts, then this means that the battery has completed charging ... As for why the amount of electricity consumed for charging increases, this can be known through the following illustrative example:

Suppose you want to fill a balloon with air ... In the beginning the balloon is completely empty, so it does not expend effort to enter the air in it, but after it is close to full, you make a double effort to enter new air because the balloon is almost full and it is difficult to receive more and this is exactly what happens in the battery in the beginning The battery is empty, so it is easy to fill it with electricity, but after a while the difficulty increases gradually and the amount of voltage increases until it reaches the number 4.2 volts, and this means that it is fully charged.

 How are Apple devices shipped?

Apple stated that its devices, whether iPad, iPhone or iPod Touch, show the user that they have reached 100% full charge before actually reaching this number, but at this moment the charging does not stop, but rather continues until it reaches the actual 100% and then stops so the battery is discharged A little bit then it recharges again until charging is complete to 100%, then stops and repeats this process until you disconnect the device from electricity. And I told Apple that this has happened for a long time in all its devices and nothing new, and this matter is useful in the event that you forget the phone in the charger for long periods. It also explains to us why the previous time difference occurred from 11.6 hours until the charging stopped compared to 10.4 hours upon reaching 100% because as we explained reaching the number one hundred does not mean completely charging and because the battery of the new iPad is huge and equals more than 8 times the battery of the iPhone 4S. The difference between actual and apparent charging is large because the battery is large.

Have you ever noticed that your device continues to charge after reaching 100%? Do you forget your device for long periods in the charger?
