After the release of the new iPhone 7, Apple decided to update its battery case. The new version has 26% more charge with the same dimensions. To be precise, the charge of the Smart Battery Case increased from 1877 to 2365 mAh. Interestingly, Apple itself does not talk about the case as the only solution for a shrunken phone, but positions it as a powerful case that helps keep you in touch from morning to night. iPhone 7 also received an improved battery, so the developers say that together with the Battery Case, users can talk on the phone for 26 hours and surf the Internet using the LTE network for 22 hours. The battery case can be charged independently of the smartphone; for this, a charge sensor is provided on the device case. The charging time of the smart case will be 1 hour. If you charge the case with iPhone 7, then the smartphone’s battery will be charged first, and then the case will begin to charge. When using energy, the battery of the case is always wasted first, and then the device. The Smart Battery Case is already available at the Apple branded store for $ 99.
