Here are a few tips for salvaging the length of your battery life:
1. Charge your phone throughout the day whenever you can, instead of once at night.
2. Don’t charge your phone to 100 percent, as a high voltage stresses the battery. Your battery will behave the best if you take it off the charge before it hits 100 percent.
3. Don’t keep your phone plugged in when it’s fully charged. This keeps the battery in a high-stress, high-tension state, which can wear it down.
