iPhone Sanyo Eneloop KBC-L3 Battery Longevity Roadtest

One of the biggest shortcomings of the iPhone is the dismal battery life. This is big problem if you’re on the go a lot and don’t have ready access to chargers or go partying. This leaves iPhone owners making hard choices like, should I find the restaurant I’m going to on the iPhone or accept one more phone call? Kind of ridiculous when you think about it.

I’ve been looking for a good solution (as in a spare battery) so I decided to check out Eneloops. These batteries are amazing. They have low self-discharge (hanging on to 85% of their charge sitting on a shelf for a year) and high output. So I bought the most compact Eneloop KBC-L3.

I fully charged the iPhone yesterday morning and set off about my day to see how long it would last on an Eneloop alone without plugging it into a computer at my desk or any other power source. The iPhone lasted 24 full hours after installing 5 apps, browsing the web, checking Facebook, going through Flickr through an iPhone app, and downloading emails. The Eneloop gave me roughly 1.5 full charges. Not bad. Definitely, enough power to last for a heavy night out or an extended amount of time on the road.

The only “issue” I had is, that I would have to press the Eneloop’s charge button 2-3 times to re-initiate charging when the iPhone ran really low. This is not an issue with the larger Eneloop KBC-L2. Has something to do with the heat/current setting off the safety switch. If you need something for the road, I highly recommend it.
