There’s something similar to Moore’s Law happening in the arena of smartphones. Each year new phones are released with more of this, double that and a load more of everything in between. With one exception: battery life.
Remember your trusty Nokia 6210?
I can remember going away for the weekend with one of these guys, the thought of bringing a charger was definitely optional.
Not so with our current iPhones.
Part of the presentation at a new iPhone launch is invariably something on battery life; “it’s increased by X%” but it never really translates into much in the real world. Sure I understand, there’s a lot going on inside a modern iPhone, a lot to drain the battery very quickly. I’m also sure that there’s research going on to come up with new ways of powering these devices, in the mean time we have to find other solutions.
When away from the office this is what my day usually looks like, yes that’s 9 am and already down to 30% battery.
Enter the recharging iPhone case
These are not new, various manufactures have produced cases for a number of years now that are capable of re-charing your iPhone throughout the day.
What is happening though is that they’re getting thinner and more powerful, which are the two key features you’re looking for in a product like this.
The MiLi Power Spring 5
I’ve recently been using the MiLi charging case, it’s certainly a great little device. It snaps onto the iPhone 5S and feels snug when installed. It does add a little bit of thickness to the phone but it’s not ridiculous. When trying to stick it in the back pocket of your jeans it fits well, in reality it’s not much thicker than many standard cases.
The MiLi’s hard plastic shell feels good in your hand while being rugged enough to protect your phone if you drop it.
Obviously, you need to plug the case into your iPhone. There are two methods I’ve seen on the market. Either the case is bigger than the phone and the connection is inside the case or there is a cable that is outside the case that plugs into the iPhone’s lightning connectors. The MiLi is the second of these two.
I think there a pros and cons to each method. The plus side of the cable on the outside is the case can be the same size as the iPhone – which I don’t mind at all.
The core focus of the product is power, so a nice touch on the back of the case is LED display that shows you how much juice you’ve got left. It also indicates when the case is being charged.
To charge the case itself there’s a USB cable provided, it’s standard USB one end and mini the other. I like this as you can plugin it into a standard iPhone charger or of course any USB port on your Mac.
