Batteries absolutely hate heat - don't leave your phone in a hot car. Try to keep your phone above 20% if you can (more stress at 0%).
Most of all, enjoy the phone. The battery will easily last 2-3 years with normal usage. My wife doesn't care about her battery at all - regularly drops it to 0% till it shuts off. Her battery life is within 2-3% of mine after 2 years and I baby my battery.
