I was able to test out the new Apple iPad charger and it works just like the old one. It charges quickly and then slows down significantly before getting to 100%. In fact, from my calculations, the time it took to go from 1% to 80% was about the same time it took to go from 80% to 100%.
In this article, I’ll explain the basics of charging Apple products. Hopefully, you will have a better understanding of what is going on and be able to provide your own insights. If you are an engineer or someone who knows a lot about this topic, feel free to post your thoughts in the comments!
Power Sources vs Chargers
A power source is a device that provides electricity to your Apple device. A charger is a device that charges your Apple device.
This statement is inaccurate because it omits the important detail that the power source for an iPhone, iPad or iPod is not the wall. The power source for these devices is actually a charger that you plug into the wall.
The charger inside the iPhone or iPad controls the flow of current into the device, not the adapter. If you ever have checked, the iPhone adapter is rated at 5 watts and 1 amp. The iPad adapter is rated at 10 watts and 2.1 amps.
The iPhone and iPad Charger
The battery in your iPad or iPhone is a rechargeable lithium-ion polymer battery. It’s what Apple uses for all their devices, including Mac computers. Apple has a great page that explains a bit about their battery technology, but the best part is this chart they provide: The battery in your iPad or iPhone has a capacity of 10 hours. This means that it can last for up to 10 hours of use before needing to be recharged.
The chart shows that when you charge your device at a fast rate, it will reach the 80% mark in about 25 minutes. However, if you charge at a slow rate, it will take much longer to reach the 80% mark. This is because the device is using up energy from the battery in order to charge.
The iPhone and iPad continue to draw power from the charger even when the device is not being used, a feature called “trickle charging.” This happens because the devices are constantly checking in with the charger to see how much power it has left. When the battery reaches 100% it will stop charging. ..
Why Do We Need Trickle Charging?
So, if you’re ever in a situation where you have to charge your battery up quickly, trickle charge it instead. It’ll do the job just as well and won’t overcharge your battery.
trickle charging solves this problem by reducing the current at the latter part of the charging and completely stopping it once the battery is fully charged. That is why it is also not harmful to leave your device connected to a power source even after it has fully charged. ..
In conclusion, the charger is inside your device and the thing you plug into the wall is the power adapter, not the charger! All this technology is there to basically preserve your battery life over many charge cycles. If you have any questions, let us know in the comments! Enjoy!
