As we all know, the built-in battery capacity of the iPhone 6s is only 1715mAh, which is far from that of the iPhone 6s Plus in terms of battery life. For heavy users, it is inevitable to charge several times a day. There are many kinds of protective cases on the market that can charge the iPhone, but these products are often thick and heavy, often with poor hand feel.

Apple may have seen the profit margin in mobile phone accessories, and recently launched the official charging protective case "iPhone 6s Smart Battery Case". The shell is made of silica gel, and the interior is made of soft microfiber, which is available in carbon gray and white.

As for this protective case, its appearance can only be said that... the overall shape is poor, the built-in battery of the back cover is obviously prominent, and the chin is too narrow and long because of the use of Lightning interface for charging. It is not enough to say that it is Apple's ugliest accessory product ever. Apple's official website did not specify the battery capacity of this product, but only marked it as "extended to 25 hours of talk time, up to 18 hours of LTE Internet use time", and wearing this protective case will not affect the use of Lightning interface, including charging and data transmission. (Many third-party battery cases can also transmit data.)

As for the price, the price of the protective case is - 848 yuan. Yes, you can see it correctly. The price of this official protective case is up to 848 yuan. what! You said you would spend 848 yuan to buy a protective shell without aesthetic feeling?
