"I fixed my Adventure Sync (Android, Galaxy 8+ and 9+) and you can, too!"

#PokemonGO: Turns out there are TWO battery saving functions on these devices. One of them is a general "Power Saving" function that you can just turn on and off from the pull down menu at the top, the same way you turn on flashlight, airplane mode, etc.The second one is MUCH sneakier, and is targeted at individual apps. Here is how to fix it:*Settings (gear at the top, when you swipe down from the top of your home screen.)*Device Maintenance*Battery (bottom left) This will pop up a screen with "power saving mode" where you can choose "off" "mid" "max"...make sure this is off, of course.Then scroll down a bit, and you will see a list of apps, with the icon "save power" above them. (DON'T touch that icon.)Just under that list of apps in tiny little font is a pull down menu that says "sleeping apps" with a number after it.*Pull down the "sleeping apps" menu.You will see a list of applications that your device has chosen to put to sleep "when you're not using them." Click on Google Fit. Once that menu opens, you'll see a list of items that look greyed out. "Mobile data" "battery" "storage"...*Click on "Battery." You can do this, even tho it LOOKS greyed out. Down at the very bottom, under the heading "Manage Battery Usage" you will see "Optimize battery usage." Click on that. It will, once again, pop up a list of apps. There is a pull down menu at the top, click on the little triangle and:*Click "all apps." Scroll down to "Fit" and make sure the switch for optimizing battery usage is OFF!Do the same for Pokemon Go, of course.There you have it.I got a half a km distance doing chores tonight for the first time in MONTHS.I hope this helps others.Edit: thank you for my first gold, kind internet stranger! via /r/TheSilphRoad http://bit.ly/2IHp9y8
