(CNN) - A long day of running errands, a flight delay, or a concert or sporting event can leave smartphone users without an outlet to recharge – and that dwindling battery often leaves us seeing red.

Restoring a smartphone battery to full charge can take as long as an hour. So smartphone users took notice when an Israeli startup called Storedot recently posted a YouTube video with a prototype for technology that would charge a zapped mobile phone battery in a mere thirty seconds.

The company says it'll be about two years before they'll get a product on the market, so until then, here are some tips smartphone users can keep in mind to save battery life.

- Adjust settings so the phone goes into standby mode or status after a minute or two, rather than ten or fifteen.

- Lower the brightness of the phone's display and disable the auto-brightness feature.

- Location-based apps can also drain a battery quickly. Look for the GPS icon in the upper corner of the phone's screen and disable location services if you're trying to save juice.

- Also disable automatic downloads of apps and music, and close those apps when not using them so they don't run in the background.

- If you're one of those people who knows they'll frequently go a long time between charges, invest in a battery case for your phone, to always have backup.
