How can I utilise my old Android device? - Infosec.Pub

I have a moto g2 lying around for some years. I was wondering if there is anything I can use it for? I don’t plan on inserting a SIM card on it and the battery capacity on it must have reduced quite a lot by now. Can you suggest some ideas which can prevent it from becoming e-waste? (If it hasn’t already become e-waste)

Get one of those telescoping type-C game controllers and turn it into a poor man’s Logitech G Cloud. Those controllers usually have a battery in them, to top up the weak battery in the old phone. Use it on Wifi for Xbox Streaming or Moonlight, or put a SIM card in it for Xbox Game Pass of Geforce Now on the go.
Got a recommendation for something that has a battery? I think the Gamesir one is nice but I’d like one that can charge the phone like you’re suggesting!
