I am precisely doing that since my xiaomi drowned last month. Got myself a spare/ secondary phone that happens to be my primary at the moment. It has another feature I wanted to try: an eink screen, black and white, easy on my eyes (model: bigme hibreak).

I am happy with my decision :) it's like a digital detox in its own way... Most of my app consumption was text > sound >> video, and the latter doesn't look bad at all anyway, so... here we are. Only some content received via Whatsapp but I use the web version at my pc most of the day (e.g. videos of my family or photos from friends)
