Never used wireless charging but also never really understood what is so dramatically elevating about it. Is it just the requirement for 1 hand vs. 2 hands that people find so life-changing? Doesn't it waste a ton of power in the process?

It's one of those things that you don't think you'd need until you have had it, and then wonder why you've gone so far in life without it.

As someone who constantly has to step away from my desk during the day, I don't have to think about charging the phone anymore. It automatically goes on the wireless stand (directly in front of me) when I'm back at my desk. I can be certain that if I choose to go out for the evening after work, I wouldn't have to worry about being stranded somewhere far from home because my phone died. (Side note: Uber and Lyft have really decimated the taxi industry, even for a downtown area in a medium-size city.)

Oh I see. But putting it in the charger all the time just makes the battery die more quickly, right? Though I see the value now if you don't care about that.

Apple specifically has software features to protect the battery from the consequences of that usage pattern.

It might lose some life from keeping the battery at a high level, but it will gain life from using the battery less.

If you can keep it from charging too high, it's all upside.

The last 10-20% of the charging causes most battery wear (many times more than in the mid band). So charging from almost-full to full many times per day is going to be harder on the battery than charging fewer times per day.

This is especially pronounced on phones, where batteries are already calibrated to have a high charge cutoff (ie battery longevity vs capacity compromise is heavily at the capacity end).

What I don't get is why phones can't be configured to just never charge past 80% or so, for people who rarely need that 100%, and would rather the battery wear less.

It's a thing for some laptops; e.g. Lenovo specifically advertises such a setting.

Apparently you can do it on rooted Android, though I haven't tried it (eg https://www.androidexplained.com/battery-charge-limit/)

You need it to work around the inability to charge while using headphones.

(Not using wireless charging either)

One advantage is that it does not destroy the USB port. Constant plugging and unplugging can really wear some ports after 1-2 years, depending on manufacturing quality. To the point that it won't charge anymore. (Hopefully will be less of an issue with USB-C which seems better designed than microUSB). Plus the convenience.

A cheap workaround for me is to use magnetic USB connectors & cables. They are small enough to have a connector permanently attached to most my devices and I have several matching cables on my desk, in the car etc.

I found about this option on a motorcycle forum where a specific helmet headset was quite sensible to breaking the micro USB charging port. I bought a couple of cables and several micro-SUB connectors, then I bought a handful of USB-C ones and a few more cables and now everything is by default using magnetic connections.

To counter that though, it's not nearly as efficient and the additional heat definitely puts more stress on the battery possibly lowering it's lifespan.

[ss3000]

My hunch is that you're probably correct about the heat effects of wireless charging on battery lifespan to some degree, but I'd love to see more emperical studies on the topic. Especially comparing it to usage of wired quick charge solutions that tend to result in much higher spikes in temperature than wireless charging, but over a shorter timespan. It's not obvious to me that one would be more harmful to battery lifespan than the other.

Newer wireless chargers also usually have some form of active heat management (i.e. fans), and anecdotally my phone only ever gets lukewarm to the touch, even with a somewhat bulky case on it.

At the end of the day though, I personally wouldn't mind having to upgrade my phone slightly faster than I would otherwise in order to enjoy the convenience offered by wireless charging, but definitely speaking from a position of privilege here.

Seems like an expensive way to workaround a weak port
