Don't charge the battery but use connected power to run the phone

Answers to this question https://android.stackexchange.com/q/130000/131553 explain how charging while phone is in use does both - charging the battery **and** powering the on going activities. My question is different — **Can I stop charging the battery but use the connected power for ongoing activities?** *Why do I want to do this?* * I want to charge the battery within ideal limits (see https://android.stackexchange.com/q/156526/131553) and * at the same time use the charging power to keep running the phone without any heat stress on battery, thus extending battery life. * Also the battery is not drained, enabling me to use the phone for longer time without charging Edit : I am not looking for dedicated cables or hardware that can possibly do this
