The iPhone 16e, which arrived yesterday, February 28, has a long-lasting rechargeable battery, probably due to its low power consumption.Today, March 1, I recharged the battery for the first time since I purchased it because the capacity of the rechargeable battery was about 3% in the evening.At that time, I measured the capacity of the rechargeable battery with a USB tester, so I am writing about it here.

The iPhone 16e consumes less power

I started using it yesterday, February 28th around 12:00am with 80% charge, it was down to 30% when I woke up this morning and 3% in the evening.

Although it may depend on how the system is used, the system will last until the evening at 30% in the morning, which is probably a low power consumption.

Amount of electricity to fully charge the battery

The battery was charged for the first time from the point where the charge level reached 3%.At that time, we charged the battery through a USB tester and measured the capacity of the rechargeable battery.The USB tester used was the following product.

Charging started at 17:00 from a 65W Type-C adapter.Immediately after charging starts, the battery is charging at about 25W (8.5V, 2.9A).

Here it is at about 17:20, with 722 mAh and 6.5 Wh (34%) charged, at about 24W as it was right at the start.The temperature rose a little to 43°C.The unit felt a little warm to the touch.

Here it is at about 18:45, with 2424 mAh and 18.8 Wh (97%) charged, the voltage has dropped to 5.0 V and the current has dropped to 0.5 A.

When I checked the battery around 19:20, it was fully charged.The amount of charge was 2,552 mAh or 19.4 Wh.Since the voltage and current seem to be controlled according to the amount of charge, the mAh amount cannot be relied upon.The capacity of the rechargeable battery is about 19.4 Wh = 3,900 mAh at 5V conversion.

I was able to charge my iPhone 16e from a 3% rechargeable battery to over 95% in about 2 hours.In the beginning, the battery is charged at 24-25W, and then lowered to about 2W in the middle.Is this to protect the rechargeable battery?

The capacity of the rechargeable battery is 19.4 Wh, or 3,900 mAh at 5V equivalent.It should last for about two days if used in the same way as today.

The capacity of the rechargeable battery is information that has not been officially released.We hope this information will be helpful.
