If you’re dealing with a fully charged battery that’s relatively new and in perfect condition, it will take 2-3 months for it to lose all of its charge. If you have an older battery, you may need to wait a bit longer. The battery’s capacity is measured in milliamp-hours (mAh), which is a measure of the amount of energy that can be stored in a given volume of space.

The more energy you can store, the longer it takes to charge the battery. For example, if your battery has a capacity of 1,000 mAh, and you charge it with 100 mA (milliamps), it would take 1.5 hours for the charge to reach 100% capacity. This means that if you use your phone for 10 hours a day, then you would only be able to use it for 2 hours before it runs out of juice.
