If you've been playing Pokemon Go for a while you've probably noticed your battery is taking a huge hit, so here's a few tips to help you get the most out of each charge.
Click on the Pokeball at the bottom of the screen.
Now go to settings.
And then pick the box beside Battery Saver option.
First, you'll need to find a Pokemon.
Once you target it, you'll see a AR toggle appear on the top of the screen.
Slide it to the left and you'll no longer see the [UNKNOWN] in front of View.
This one is more of a last resort move.
Go to your display settings, or just slide to view your shortcuts and turn off auto brightness and adjust.
