I've been using duet display for using iPad as an external display for nearly two years.
The main negative outcome of such setup is degrading the battery life of the tablet/phone when used with the cable for better latency.
I think if people use sidecar with USB cable for charging all the time, soon Apple might remove the feature due to battery replacement complaints.
- marinhero 6y agoCan you elaborate on the topic of battery degradation? isn't this a scenario that the iPad was built for? how would it be different from hours of watching videos?
- sbierwagen 6y agoIf it lives on a cable, the battery will always be at 100%, which Apple says reduces battery lifespan: https://support.apple.com/en-us/HT210512 https://support.apple.com/en-us/HT210512

- D13Fd 6y agoI've found that it's fine as long as you have your laptop plugged in. Before COVID I worded every day on a Macbook Pro 16 with an iPad Pro w/ Luna as my second display. Everything stayed at full charge. I'll also mention that for whatever reason Luna works far better than Duet. I always get black bars and lag on Duet, but Luna is generally flawless (except for the occasional crash or random switch from wired->wireless connection).
- httpsterio 6y agoIf Macs and iPads are able to bypass the battery entirely and power the hardware directly through the charger, then it shouldn't have an effect on the battery. But it's also possible that it's just charging the battery while also using which will shorten the battery life, especially as you don't allow it to do full power cycles.
