If you want to install the iOS 14 beta, using a battery case might fix one of the issues that come from installing a beta
The easiest solution is to buy a power bank and keep it with you all day. The downside to this is that you might need one with a huge capacity. For example, we’ve used a 30000mAh bank and it has much more power than you would need to use throughout the course of a day; while great for those camping trips or in case a storm causes a prolonged power outage, it also is not what you might call pocketable. Even a smaller power bank has to stay attached to your iPhone via a charging cable.
This is how you download the iOS 14 beta on your iPhone
Keep in mind that reduced battery life is only one of the issues that could pop up when installing the iOS 14 beta. Most likely in early September, the final version of iOS 14 will be released and your iPhone’s battery life should return to normal and hopefully, all of the bugs will be exterminated. But if it is battery life fears alone keeping you away from checking out the iOS 14 beta, a battery case can be a good way to soothe those fears so that you can be the first on your block to use App Clips.
