I got my first Oneplus phone earlier this year and the fast charging is such a nice convenience. I thought it’d just be a gimmick I wouldn’t care about, but its something I take advantage of basically everyday.
In the past I’ve used Pixels and Galaxys and they tend to claim they have fast charging, but in reality its pretty slow. My old Fold 3 took ~1.5 hours to fully charge.
For comparison, the Oneplus 11 I replaced it with fully charges in under half an hour, usually closer to 25 minutes (though I very rarely actually charge up to 100%).
I bought a second charger to keep in my backpack and it basically completely removes any battery anxiety that I used to have. The other day I was out after work and my phone was down to 5%. I saw that I was near a used bookstore, so I went in and charged my phone for 5 minutes while I looked around and I was back up to 35%, enough for several hours of screen on time.
True, when my phone is idle on my desk for hours, it’s plugged on a old 5V 1A charger to charge slowly. But if I have to get out for a long time and the phone is at 30%, I plug it on the 33W charger (it charges at 11V 3A) and in 15 minutes it goes to 80% or something, good enough.
I only “fast charge” (it is a 33W charger I think) when I want it… Well fast, I have a similar charger like yours and leave it plugged in all night, because I have been using my phone a lot as of lately (you won’t guess where) and I need it completely full.
