It does matter. Modern smartphones have such abysmally short battery life that I have to charge my Samsung S6 twice during the day, in addition to the overnight charge. Which makes a slow Qi charger useless during the day.

Battery life seems to be almost entirely down to how much you're actually using it. My work Samsung Galaxy A5 (2017) lasts several days (really) because I only look do email and calendar stuff on it, a few times a day.

My iPhone 6s often lasts through the day and half way through the next, when I'm not doing much other than playing Spotify and using a bit of WhatsApp. If I'm actively using it, though, I have to plug it in towards the end of the day.

Depends on the modern smartphone, I have a Xiaomi Redmi Note 4 and it has amazingly good battery life (much better than my company-supplied Samsung Galaxy S8), I can sometimes go two days without charging.

They do cheat with ridiculous background app-killing "features" though (I've tweaked it to my liking and now prefer it)

when i'm in the office, i leave my phone on the bay to charge. i don't literally use my phone while charging, but i do pick it up from time to time to check notifications and then put it back on the bay. so it pretty much charges all day. it probably won't save me more than a second or two every time i pick it up and put it back down, but it's become so second nature to simply drop it on the table without looking that i can't imagine going back to a system where i have to use both hands (and more than an eye) to get a phone charging.

when i'm out, and if i know i will be out for a long time, i'll bring a battery along.

at night, it charges on the bay when i'm asleep.
