Why does 10w huawei charger, charges faster than a 12w apple charger?

[pagalas]

So I have noticed that my 12w apple charger charges my phone slowly than my huawei charger.

I have used an app for jailbroken devices to monitor the current while you are charging.


These were the images of the currents that I got while charging:

As you can see with the 1st pic it only charges about 400mA (12w charger) while on the 2nd pic it charges for 700mA(10w charger).

So I wonder why is it like that? The apple charger was supposed to charge the phone faster right? Is there some kind of chip in the apple charger that regulates the current?

Please do note that I have 2 12w adapter that came with my iPads and the currents that I got were similar when I tried to use both.

I am no battery scientist, but its probably due to Apple enabling some kind of dynamic limiter to best protect battery chemistry for the long run. I don't think Huawei cares a rats hoot about how its battery performs after the initial hardware sale, whereas Apple took a lot of heat a couple of years ago over battery life on 2-year old hardware.

iPhone is detecting the 12W charger as a 5W charger. Maybe the jailbreak is causing problems.

Doesn't make sense because the power management IC is on the iPhone, not the charger. The iPhone has 100% authority on the rate of charge.

I doubt there’s a correlation between the jailbreak and about the charging.

My phone registers the 12w iPad charger as 12 watts so something is going on with your phone or the charger/cord..

Im using the same cable to charge my phone and only the adapters were interchanged.
