I steadily advocate using a computer for various internet tasks. 55% of internet traffic is by smartphone. Smartphones are good and convenient. I finally got one myself. But computers are more powerful. If you can use one and you do, you can limit your device screen time and do what you want more easily.
If you have a Chromebook, a Windows machine, a Mac, an iPad, a smartphone, a Kindle, another Kindle and older Chromebook that no longer qualifies for updates, you can spend the last hour of every day checking to see which devices need to be re-charged overnight. You have probably read that it is better for battery life of many devices to let them run down to close to empty before charging them up. Battery technology, like many other aspects of today's electronics, changes and different batteries advocate different practices.
Things can get more complicated when some devices age or no longer qualify for official updates. At that point, you may want to dispose of them or give them to relatives or friends that can make use of them. It is sometimes a bit of a question as to whether giving older devices away is a help to people or a hindrance. Theoretically, newer devices are better designed and more up-to-date with current technology. Of course, some changes are not all that important and a few may be actually worse than older versions.
The very use of the word "devices" reminds us that much of today's stuff didn't exist a few years back. I haven't mentioned "IoT"( the internet of things) such as a smart vacuum cleaner or a smartwatch. There is a possibility of devices that need to be recharged but that perform such different tasks that we don't even know what to call them. And between our car, our kitchen, our outside grounds and our desks, we simply forget the drone that needs to be charged or the security camera in the dog's collar. And don't forget to check your Kobo reader and that Nook. And what about the backyard trail camera?
