well if u r using Gboard (i recommend u use it better than Samsung's keyboard) then go to settings>language and in input>on-screen keyboard>Gboard>preference> turn on haptic feedbacks on keyboard and then increase the vibration strength in as per requirement. Attaching screenshot also.
it's better than Samsung.yup battery remains same. try it's Google's product.whenever i change fone typing doesn't affect coz there's already same keyboard available with personalisation
