We desperately need a full battery charge alarm. This will help us to disconnect the charging as soon as its battery is full thus saving the battery overall health.
All modern phones these days self disconnect from the charge if you put your phone in charging docks or plugs. So full battery alarm is not required. My phone always stays on the wireless charge when I'm in office I pick up and put down the phone on the wireless charge pad all the time and believe I haven't seen battery malfunction at all.
There is a theroy for both. Keep your phone off the charging plug or stays in. But all modern phones doesnt need such features rather if you keep your phone at around battery level all the time it will help improve the battery instead.
