Since I took the plunge and got a smartphone, the thing I miss most about having an old non-smart phone is the battery life. When I get my phone out and start using it, the battery life just very slowly dissipates with every click of the on-screen icons. It’s incredible to behold. I used to get all day on my phone’s charge, even though it wasn’t exactly a useful phone. Now I have a phone that can do pretty much anything, and it’s got to be charged routinely or it becomes an expensive brick. That charging process usually means I’m tethered to the wall, but a Chinese phone manufacturer is working on that issue. Huawei has developed a cell phone battery that charges 10 times faster than current batteries.
The battery works not by being substantially different from standard batteries mechanically, but by changing how lithium ions are stored and move inside the battery. In five minutes, the phone charges from dead to 48 percent capacity! There are other companies working on ways to charge phone batteries wirelessly, and others are working on phones that don’t need charging for up to 7 days. Maybe if you combine multiple technologies, you can finally solve the biggest problem with modern phones: battery life!
