Why does turning computers off and then back on again fix so many issues?

My phone wouldn’t connect to the wireless charger I have in my office. Quick google search tells me to power it off, let it sit for a few minutes, and then turn back on. BAM! Connects immediately.

Why does turning it off and then back on again work so well for so many computer drivers devices?

Long answer short...it clears out stale, bad data that is hanging up the application. The reboot allows the app to get a fresh, clean start. Like notsince98 said, app developers are supposed to clean up after themselves in their code but that doesn't happen nearly as often as it should.

I've told my wife if I'm ever on life support, unplug me. Then plug me back in, see if that helps.

Most little bits of computer frickiness are caused by one of the million little scripts running behind the scenes failing. You could spend dozens of hours trying to figure out which it was, then restart it manually. Or, you could just restart the entire system, which restarts every script, including presumably the one that shite the bed. Problem solved by brute force.

Microsoft and Google are anyway. Their software in particular is what seems to eat memory and cause Windows to run like trash.

In one word, cache, a reboot clears it out and gives you a fresh start.

How often should we be restarting phones? And, is powering down ever needed/good?

When I worked in corporate support at a major manufacturer, I would use a version of this Sophie's choice all the time. "Sir, we can spend the next two hours unplugging things and rebooting, and hunting down a corrupted driver, or, we can restore the system to factory configs, and you go get a coffee and wait half an hour."

They tell you they can't afford half an hour of downtime (maybe even telling you what that would cost them), then you spend two hours trying to find the ghost in the machine, still can't figure it out, and end up restoring the system anyway

When they start acting fricky. No real need to make a habit out of it. I very rarely restart my phone, but if I am, 90% of the time it's because it's running hot at idle, which means some dumbshit app in the background isn't idling itself properly, so instead of trying to figure out which it is, I just do a restart. Saves a lot of headache. And battery.

I had a user that worked for the Louisiana Department of Education call me once. I needed to ship her a part. She was spelling out the street name, and said, "K as in cat."

You better clarify those directions to make sure she plugs you back in within a minute and not a few hours later

Why do you run better after a fresh dump?

Clears the old shite out.
