Same phone here. Also try to have as much turned of if not needed. Keep screen light at minimum. Also use: Face slim, Privacy browser, Smarter wifi manager, Dimmer, Materialistic :D (writing the this comment) All sorts apps, I just try to avoid the ones that keep running on background, or autostart. Unless I really need it. My realtime communication availability is obviously sms and phone call. The phone has 1 year. Charged it this morning. It is at 80%. Been on web, facebook, hackernews...
