Obviously this will depend on what iPad / tablet you’re using & exactly what you’re working on, but I’m curious to know what’s ‘normal’ if that’s possible.
Today I sculpted for apparently only 2.15 hours on my 2021 M1 iPad pro & the battery went from full to 5% in that time.
I was working with low res shapes, mostly in mat cap, occasionally subdividing as I went on & switching to lit pbr w/ post processing occasionally to check my progress under different conditions.
When I started my brightness was approx 80% so I turned that down to 60%ish when I realised I’d hit 35% battery a bit faster than I’d like, I also had Pinterest open for reference & hadn’t closed down safari & Spotify in the background, but still I was surprised at how quickly it drained. I may be wrong but I don’t think it used to run out so fast, could I have I knackered my battery in less than 2 years?
