Secondary Smartphone

A while ago I was introduced to the concept of a secondary mobile device. The idea is that one's primary phone, the one that has an always-on connection to one's cellular network, is used strictly for actual communication purposes; another device, which can only access WiFi, is used to store things like games and social media. As someone who likes to embrace the Unix philosophy in his daily life, this system sounds quite appealing to me.
The secondary-device paradigm isn't entirely new. Palm tried it in 2018 with the Palm Companion Device, but it didn't sell very well, likely because it was limited to Verizon and couldn't be used as a standalone smartphone. Recently, though, the idea has become popular in the digital-minimalism and social-media-detox spaces. A current example is the Clicks Communicator^, a full-fledged smartphone that markets itself as a companion device alongside one's current daily-driver smartphone.
I've been interested in this concept for a while. When I finally received my Pro1 X from F(x)tec in November of 2023, I had intended for it to be my daily-driver phone. I soon discovered that it was missing a key antenna frequency that made it almost impossible to use in my area on my provider. I ended up switching back to a carrier-supplied device, at which point the Pro1 X ended up unused and collecting dust in my basement. It didn't take long to come up with the idea of moving apps to it that I didn't use or wanted to break an addiction to. However, the Pro1 X is a relatively fragile phone, with no case and no screen protector, and spare parts are very hard to come by.
Now that I own a Unihertz Titan, as well as plenty of spare parts for the Pro1 X, I'm ready to explore a secondary device more seriously. However, while they're both keyboard smartphones, the Titan and the Pro1 X are suited for slightly different use cases. The Titan's keyboard is easier for my large thumbs to type on, and its large square display is comfortable to read text on; meanwhile. the Pro1 X has official LineageOS support and is better for media consumption. I dislike watching YouTube on the Titan, and I dislike typing terminal commands on the Pro1 X. My solution? Use them both.
In my shoulder bag, I now carry my primary phone (a Samsung Galaxy A15) with a second phone, and I swap between the Titan and the Pro1 X as my secondary. Both have advantages and disadvantages, and they're currently configured to do sightly different things. I already notice a huge difference in battery life across all 3 devices: my A15 only handles calls and messages now, my Titan doesn't drain itself playing YouTube all day, and the Pro1 X isn't bogged down with terminal operations.
I'm determined to try this paradigm for a month or so and see how I like it. It's possible I might come to hate it, and I end up selling all my secondary devices and go straight back to one smartphone containing everything. For now, I enjoy splitting functions out by device and better managing the time I spend on those functions as a result. And let' be honest: both the Titan and the Pro1 X just look cool.
