Battery - how to treat to expand lifetime (Optimal Charging Tips)

I read somewhere that you can expand a battery’s life by trying to hold the condition between 30 and 70 % and once a month you should discharge it completely and after that load it completely. Is that right? Or do you have any other recommendations? And by the way, is there any possibility to see the battery condition in % on home screen?
