On my device the charge is set to cut off at 91%, with the maximum charge current set to 500mA. If I'm in a hurry though I typically boost the max current to 1.1A, or the manufacturer's 2.7A if absolutely necessary (although I think that's a bit high personally).

To be honest a 1A max charge current would be a good balance between charge time and battery longevity IMO - the main purpose of the lower charge current is to reduce internal battery heat during charging, change the growth characteristics of lithium dendrite clumping within the battery, and reduce the chance of the battery swelling.

I also try to not discharge below 30%.

I'm not an expert on any of this at all though, I just mainly follow Battery University and some takeaways from a handful of research papers analyzing Lithium-based batteries
