Review: Tylt Energi Sliding Power Case for iPhone 6 Plus

Tylt’s Energi Sliding Power Case for iPhone 6 Plus ($100) is one of few iPhone 6 Plus battery cases to hit the market thus far. Energi for iPhone 6 Plus has the same design as the iPhone 6 version of the case — the phone fits in a slim standalone case which can then be inserted in a battery sleeve with built-in Lightning connector for recharging the 6 Plus. The battery capacity gets a bump up to 3500 mAh in the iPhone 6 Plus case, but the price remains the same. A micro-USB cable comes with the case.

We’ve already focused on the basics of the case in the review of the iPhone 6 Energi case, and the same features remain here. It’s a thoughtful, well-designed case, just larger for the iPhone 6 Plus. The biggest difference between the two cases is seen in the battery performance. While Tylt promises to double the battery capacity of the iPhone 6 Plus, our tests found that wasn’t quite the case.

Tylt’s case charged quickly, but it didn’t hit 100 percent. In our first test, Energi delivered an 87 percent charge to the iPhone 6 Plus in 1:34. A follow-up test showed a slight improvement, with a 91 percent charge delivered in a fast 1:30. Capacity shouldn’t be an issue — Energi has a 3500 mAh battery compared to 6 Plus’ 2915 mAh battery. While the newer iPhones slow down a recharge when nearing 100 percent, that shouldn’t have been a factor in the range where Tylt’s Energi stopped.

Energi is still a good case/battery option for iPhone 6 Plus. Unfortunately, while the iPhone 6 version of the case delivered a 120 percent charge to that device, Energi for iPhone 6 Plus doesn’t quite “double the capacity” as Tylt claims. The design is still clever though, and most users will be plenty satisfied with a fast 90 percent charge for a phone which already has very good battery life. Energi for iPhone 6 Plus earns our general recommendation.
