It’s a universal truth that battery life on phones is bad. But it didn’t use to be this way: back in the (relatively) old days, phones had (relatively) fantastic battery life, lasting for multiple days at a time without needing to be charged. And, yes, our phones today are vastly more powerful than, say, a Nokia 3310, but why haven’t batteries kept up with the pace of progress? Researchers are already investigating new battery technology, like solid-state batteries, that could open the door to more energy-dense materials that could offer more power for future devices. There is a catch, though: by the time those new batteries roll around, our phones may be even more advanced and need even more power, which could leave us right back with the same, one-day battery life that we have now.
