It seems that even Apple is frustrated with the iPhone’s abbreviated battery life.
蘋果似乎也對iPhone異常短的電池壽命感到挫敗。

The Cupertino company on Tuesday joined a cadre of accessory makers and released a new battery case for its smartphone. The $100 case, designed for the iPhone 6s, the smaller of the two current iPhone models, promises to boost the device’s talk time to 25 hours and its Internet time over the cell phone networks to 18 hours. Without the battery pack, Apple promises the phone will give 14 hours of talk time and 10 hours of Internet usage. But many owners find that they often get less than that.
當地時間12月8日，這家位于庫比蒂諾的公司效仿一眾配件制造商，發布了針對蘋果手機的新款電池盒。這個售價100美元的電池盒專為iPhone 6s設計，據稱能將設備通話時間提升到25小時，將手機上網時間延長到18小時。而沒有這個電池盒，蘋果手機通話時間為14小時，網絡使用時間為10小時。不過很多用戶發現他們的電池使用時間遠低于這個數值。

The case’s design seems a bit out of step with Apple’s typical aesthetic. It only comes in two colors — white and black. And rather then mimicking the slick, thin design of the phone and other Apple products, it packs the battery in a bulge on the back.
該電池盒的設計似乎與蘋果典型的美學主義格格不入。它只有兩種顏色——黑與白，也沒有如iPhone及其它蘋果產品那般光滑輕薄的外形，而只是將電池貼在背部，凸出一塊。

The case does offer some advantages over its competitors. An iPhone can recognize when it is attached to the case, and when it displays its remaining battery power, it will reflect the boost the case provides. To ensure that it doesn’t degrade a users’ cell phone signal, the case includes a built-in antenna. And unlike many cases, it can be charged with the same Lightning cable that is used to power the iPhone itself.
相比其它競爭者，這款電池盒的確有一些優勢。當貼在這款電池盒上，iPhone即可識別它。當手機顯示剩余電量時，它還會顯示電池盒提供的額外電量。為了確保它不會減弱用戶手機信號，電池盒包含一個內置天線。與很多電池盒不同，它能使用iPhone充電線。

But other battery cases and battery backups provide far more power for the same or less money. While Apple’s battery case has a 1877 mAh battery, Mophie’s Juice Pack Reserve has one that’s nearly as big - 1840 mAh - but costs just $60. For $100, users can get Mophie’s Juice Pack Air, which has about 50 percent more battery power than Apple’s case. Oh, and Mophie and other manufacturers also offer battery cases for iPhone 6s Plus; Apple isn’t making one for it’s jumbo-sized phone.
然而，其它品牌的電池盒、備用電池可以提供更多儲備電量，有的價錢也更便宜。蘋果電池盒容量為1877毫安，而提供幾乎相同容量（1840毫安）的Mophie的Juice Pack Reserve只需要60美元，而用戶花100美元可以購買到Mophie的Juice Pack Air，后者提供的電量比蘋果電池盒多50%。此外，Mophie和其它制造商還為iPhone 6s Plus提供電池盒，而蘋果目前尚未有此類產品。

And that’s not to mention that some other phones offer much longer battery life without needing an extra case. Motorola’s Droid Maxx 2 has a built-in 3630 mAh battery - which is more than double the reported capacity of the iPhone 6s’s battery. Maybe Apple could think about making more room for a battery inside of its phones, instead of making them ever thinner.
更不用提無需電池盒即可提供更長電池壽命的其他手機。摩托羅拉Droid Maxx 2擁有3630毫安的內置電池——這大約是iPhone 6s電池容量的兩倍多。也許蘋果可以考慮在手機內部為電池多留出一些空間，而不是一味的將手機做薄。
