| It’s been long enough that people of forgotten what’s it’s like. Cameras still have replaceable batteries, there are several benefits: I can have two (or more) batteries, if it runs out I just change it. I don’t need walk around with a USB battery pack and cable hanging off the device preventing me from using it properly. I can put the battery on charge somewhere and leave it, even if not completely secure, because just the battery not the device. This way my expensive device and my data is not at risk. I can use 40+ year old cameras, because I can just put a new battery in. This is not something you can do with newer device, e.g. and iPod and you can’t even find anyone who will fit them for the older models. Battery tech moves on. There are now some batteries with charging ports on them. Other batteries offer more capacity than the original ones. Apple even did this once for me, when MacBook Air batteries were fairly easy to replace, I had mine replaced (it wore out) at the shop and they put a slightly bigger one in, which was the standard on the newer models. |
I question whether battery packs would be a good thing to bring back now. USB power banks have 100% interchangeability among many device classes, which is something that not even dry cell batteries achieved. I can choose to leave the house with or without a power bank and just rent one in my city (YMMV). Modern charging wattages are high enough that I don't miss shutting down my Nexus, changing the pack, then rebooting.
It's tempting to say that this could be solved if battery sizes were standardized, but that would inevitably limit device dimensions. For example, I especially loathe how the 18650 has made almost all modern flashlights clunky. I would hate it if Apple pushes for a 4.5mm thick battery standard to kill all foldables because they don't want to enter the market and cannibalize their iPad demand.
