" CATL has thrown its hat into the ring with the Naxtra sodium-ion battery, with 175 Wh/kg and 10,000 lifetime cycles along with operation from -40°C to 70°C. CATL is planning a start-stop battery for trucks using the technology. It has the potential to replace lead-acid batteries. CATL has announced battery pricing at the cell level in volume at $19/kWh.

Yeah, a friend of mine made a similar argument and I hear it. Personally I'm always right beside a fast charger so it's not an issue for me.

My phone has an option to auto-stop charging at 80% so I use that. I will occasionally charge it to 100% but like maybe once a month. TBH if it had an option to stop at 90% I'd probably use that as a middle ground (my steam deck does and I use 90% with it). I got 5 years out of my last phone and I'm 3 years into the current one and hoping to get many more out of it.

edit:

Personally I charge to about 95% and my phone batteries remain at 98-100% condition after 2 years of everyday use.

That's a good reference point, cheers. Do you not find it a pain to monitor that though?

I think that fast charging is almost as damaging as full cycles.

OnePlus claim it's not and a quick search does back that up. For the one specific to my phone they move a chunk of the work off the device (reducing heat on the phone) and onto the charger. It'll still charge normally with any USB charger but it gets much hotter and is much slower compared to the OnePlus "warp" charge.

Fair enough. I'm using an OP12 myself. I still don't buy into the "fast charge ok" bit, but I also know it's parallel cells and such. I still charge overnight using a 5w charger. :)
