Apple iPhone8/iPhoneX battery performance evaluation: a new generation of mobile phone battery and function

Since Apple released the iPhone 8, iPhone 8 Plus and iPhone X, it has attracted worldwide attention. Among them, the most talked about is the battery problem of Apple’s mobile phone. The Apple iPhoneX uses a dual battery and iPhone8/X wireless charging.

Since Apple released the iPhone 8, iPhone 8 Plus and iPhone X, it has attracted worldwide attention. Among them, the most talked about is the Apple’s mobile phone battery. The Apple iPhoneX uses a dual battery and iPhone8/X wireless charging.

Reduced battery capacity

The batteries of the iPhone 8 and 8 Plus, one is 1821mAh, one is 2675mAh, compared with the iPhone 7 (1960mAh) and 7 Plus (2900mAh), the battery capacity is reduced, continue to compare the iPhone 6S and 6S Plus battery, respectively, 1715mAh and 2750mAh. In other words, Apple’s new generation of mobile phones have a lower battery capacity than the 7 series mobile phones. After they have bought the iPhone 8, it is necessary to carry the charger with them.

Double battery

The biggest highlight of this new Apple mobile phone is that the iPhoneX uses dual batteries. In addition to the two motherboards, the new iPhoneX is also equipped with two batteries for the first time. “Battery A” and “Battery B” are “L” shaped. This is called “Substrate-like PCB/SLP” technology. This technology can pile up dozens of layers so as to reduce the size of the motherboard and evenly distribute more space to the battery. Therefore, there is more internal space for “Battery B”. , and A, B two batteries are connected in series.

Use up to 2 hours longer than iphone7, up to 21 hours of talk time, up to 12 hours of Internet usage, up to 13 hours of video wireless playback, up to 60 hours of audio wireless playback, and fast charging : Up to 50% charge in 30 minutes; Built-in lithium ion rechargeable battery; Wireless charging, fast charging.

Ultimately, the iPhone X’s two batteries add up to a capacity of 2700mAh, which is higher than the 1960mAh of the 4.7-inch iPhone 7, but it is 200mAh less than the 2900mAh of the previous iPhone 7Plus. This increases the area and reduces the internal capacity of the battery capacity. What exactly does it do? Apple said that the second-generation performance controller and battery design will allow the full battery life to be extended by up to two hours compared to the iPhone 7.

Wireless charging

The wireless charging that has been discussed for many years was finally realized on the iPhone X. The wireless charging is the non-contact wireless way to realize the energy transmission between the power supply and the power consumption equipment. Currently available wireless charging technologies include electromagnetic induction, magnetic resonance, radio wave, ultrasonic, infrared laser and electric field coupling. Wireless charging technology is the most widely used electromagnetic induction type, with high conversion efficiency, short-distance charging and other advantages.

Apple has created a shared charging dock for the iPhoneX, Apple watch and AirPod. Apple calls it Airpower. Electromagnetic induction unlimited charging joined iPhone8 and iPhoneX, but the wireless charging base needs to be purchased separately.
