uNu iPhone 4/4S Battery Case

The Woot-Off is dead, but these deals live on!

Smart phones do just about everything.

Judging by the battery life, smart phones are pretty busy.

Boy, iPhones sure are great. You can make calls on ‘em, play games on ‘em, navigate via GPS with ‘em, text with ‘em, price real estate with ‘em, and so much more. We could spend all day just listing ridiculous apps with which you can occupy your time. Unfortunately, odds are good that your battery would be dead long before we finished said list. Turns out doing just about everything is pretty tough on the ol’ battery.

We don’t know if it’s poor battery design or just asking too much of limited resources, but it seems like our iPhones die before we even make it into work most days. So maybe we should look into something like this uNu Protective Battery iPhone Case. It protects your iPhone while almost doubling your battery life. It’s about as minimal as most iPhone cases out there, so you don’t have to worry about it never fitting in your pocket again; and you can still sync your phone to your computer and charge it without having to take the case off.

And let’s face it, you’re going to need that extra battery life for all the screwing off you do.

Top Comments are discussion forum posts we have deemed worthy of your time. Listen, we get a lot of comments, and most of the time, it's pretty forgettable stuff; but sometimes you rise to the top like butterfat in milk. We don't recommend you base your self-worth on how often we feature your comments, but we don't expressly forbid it either.
