My single biggest takeaway from SXSW was all the talk about battery life. Every single person. All the time. People changing plans because they needed to recharge their phones. People walking around with chargers. People who were chargers. Mophies galore. People uninstalling apps that would drain power. People putting phones into airplane mode in areas of weak signal. People borrowing other phones so they didn’t have to waste the power on their phone.

Power. Power. Power.

This talk is nothing new of course, but it’s ramping up. As we transition into an LTE world, it’s going to be more and more of an issue, as Farhad Manjoo points out today. One of the most impressive things about the new iPad is the fact that it maintains the 9 to 10 hour battery life even with the addition of LTE. The next question is if they can do that with the iPhone as well. We’ll see. It’s gonna need a bigger battery.

To me, the most impressive thing about my MacBook Air isn’t its size, it’s the battery life. I routinely get 6 to 7 hours on one charge. Just a few years ago, this was unthinkable for a laptop (especially one this size). Part of that is better technology, but a large part is also simply a larger battery.

Manjoo is right that unlike the rest of the technology we use everyday, battery technology hasn’t evolved all that much over the past few decades. It’s constantly being refined and perfected, but it’s still largely the same. Want more battery life? Get a bigger battery.

If someone can truly disrupt this space, it will act as a lubricant that accelerates our already amazing pace of technological transformation. 

I want a laptop that lasts for a week on one charge. I want a cellphone that lasts a month. I want to be able to go to SXSW without a Mophie in each pocket. I don’t want to have to be constantly worrying about battery life every single time I leave my house.

Today’s battery technology is holding back several other advances in technology in major ways. And we are about to see just how bad the situation is in the coming months. Maybe wireless power sources that constantly charge and re-charge devices is the ultimate answer. But it just seems like battery technology is really ripe for disruption.
