The Chargie will certainly be useful for the many people who don't want to/can't root their phones. But it's also sad that one needs an extra piece of hardware for something that the phone can technically already accomplish on its own.
no they don't. That function is a joke. Only works maybe 2 out of 10 nights, the rest are spent at 100%. I have a Chargie (older version) and it really does the trick, every single night. I don't know how the Android app does it, but the iOS one is really transparent and just works as it should. Big thumbs up for the developer!
