How long can your phone last when its 100% charged?

Not long enough about 8 hours, it's an older phone and is losing faster now. I need to upgrade.

The whole day usually, but it also depends on what I'm doing. I discovered constant GPS use lasts me about 4 hours of driving until I run out of battery.

Since mine sits idle almost all the time, it can last several days on one charge.

6 hours

Till now.. i have to go charge it 😬
