Smartphones have integrated rechargeable batteries that, over time, can lose their ability to hold a full charge and eventually need to be replaced. To extend the life of your phone's battery, there are a few simple things you can do. First, remove the phone case if your phone gets hot when it charges. Some cases retain excess heat, which can affect battery capacity. Check the brightness level; the less "bright" your screen is, the less energy it uses. You can opt for "auto brightness," which automatically adjusts your phone screen's brightness according to the amount of light sensed by its camera.

An interesting study by the Institute of Lifecycle Analysis figured out how many times a reusable cup needs to be reused before it actually begins to save energy and resources in comparison to a throwaway paper cup. They found a reusable ceramic mug would need to be used 39 times before you begin to see environmental savings; a plastic thermos would need to be used 17 times, and a heat-resistant glass mug just 15 times. What's taken into consideration is the amount of materials and resources needed to make a reusable cup, plus the amount of water and energy to wash it. So the lesson is simple: Buy one reusable cup and use it over and over and over.

Did you know the back of your refrigerator is the coldest? And sometimes the difference in temperature is significant from the back of the fridge and to the front or the compartments in the door. This is important to know when storing your most delicate produces, like lettuces, fresh herbs and other greens like spinach and arugula. If you place these items near the back, they have a high likelihood of freezing, which can change their taste and texture. Keep these delicate greens up front so they're crisp, not frozen.
