- allarm 2y agoYou can use a smart plug that turns on when the battery drops below 20%. I’m going to use this kind of automation for a tablet with HomeAssistant in kiosk mode.
- thaumasiotes 2y agoIf the phone is old enough, you can just pop the battery out.
- jonatron 2y agoIf you don't mind disassembling and finding connectors or soldering, you can connect a power supply with the same voltage as the battery to the battery connector on the main board.
- Retr0id 2y agoThis doesn't always work nicely - sometimes the phone estimates the battery capacity and thinks it's depleting, even if the voltage is constant.
- btbuildem 2y agoI guess you increase the cost of your setup by adding an intermittent power switch / timer that turns charger power on and off. With MQTT, the server itself could drive the switch, and turn the charger on when the battery is low enough, turn it off when full enough.
- Zambyte 2y agoPhones that can have their battery removed tend to work fine plugged in with their battery removed, so that's an option. Also a good reason to make sure you don't buy a device that you can't open. I made that mistake with my current phone, and I definitely won't be making that mistake again if I get another smart phone.

- jarbus 2y agoInteresting, I’ll need to see how this affects my use case. I assumed that devices plugged into power operate on power while charging the battery, at least my laptop does.
- brucethemoose2 2y agoSome phones have limiters to keep the battery at 60%-80%. I believe most can do this with the right software. It's not a fix, but it should extend the life considerably.
- solarkraft 2y agoI've tried a few and so far it worked for all of them.
- throwaway53564 2y agoI've read that leaving phones constantly in the charger is a fire hazard. It's at leat worth checking it out before trying this at home.
