What To Look for in a Battery Case for iPhone 7/7 plus

The battery case should have some qualities to give power to your iPhone and also protect your phone. To save you time, we have prepared a checklist for you to detect what you should look for to choose the best battery case.

  • First of all, you need to choose the battery case according to your phone’s milliamp-hours(mAh). The mAh refers to the battery capacity. Like, the iPhone 7’s battery capacity is 1960mAh, and the iPhone 7 plus’s battery capacity is 2900mAh. So you will want to buy a battery case that will increase the battery life of your iPhone.
  • Secondly, you need to know that the more capacity the battery case will have, the bulkier it will be. It will add extra volume and weight to your phone, and your phone will be 100-200% heavier.

Now, don’t be afraid of the percentage. In reality, it’s not that much of a weight. Moreover, it’s a good thing because the iPhone’s are becoming thinner day by day.

  • Another important thing is, before buying the battery case, know about its charging method. Some battery cases support pass-through charging and some that don’t. 

Most of the high-end battery cases support pass-through charging. Personally, I am more comfortable with the pass-through one.

  • Look at the capacity indicators. Capacity indicators will indicate how much power is left in the battery case. Apart from the Apple iPhone 7 Smart Battery Case, every other battery case on the market has capacity indicators on its cover. 

Usually, you will see 4 LED lights in the back. Apple battery case syncs with the iPhone and shows an on-screen indicator.

You can buy your own battery case by using this checking. But to save you the hassle, we have come up with the best battery cases on the market for your iPhone 7 or 7 plus. We have chosen these battery cases based on our checklist.
