The iPhone 4 usually does a great job of lasting all day before the battery runs out, but on those days when you are out of the office and using your iPhone the most, you may find your battery running low in the afternoon, which means it is time to use a battery to recharge the iPhone. I’ve long been a fan of the RichardSolo batteries because they are tiny enough to carry around, but the downside is that they hang off the iPhone when attached — not a problem if you are at a desk, but awkward if you are on the go. The solution is to use an iPhone case that doubles as a battery. XPAL Power recently sent me a free review unit of its $70 PowerSkin case and battery for the iPhone. It works very well.
It is very quick and easy to insert an iPhone 4 into a PowerSkin. Just slide the iPhone into the connector at the bottom of the unit and then fit the silicone rubber around the iPhone. If you look at a picture of the book of the PowerSkin, there is a line near the top that makes it appear as if there are two parts, but this is a one-piece design so you don’t have to worry about it coming apart.
