I changed 3 hidden Android settings and my phone suddenly had more battery life

Even though Android still impresses me 15 years later, that doesn’t mean there isn’t room to make it better. In fact, every time I set up a new Android phone, there’s a bit of a checklist I run through to instantly improve battery life and make the UI feel faster. The best part about these changes is that they are all tweaks you can make without additional software (even though Android has many great, must-have free apps); you just have to know which settings to look for and how to change them. With these changes, I was able to get an easy 10% boost in battery life, and you can too.
