Can you please provide instructions including factory firmware images in order to downgrade my Moto G 2015 from Android 6.0 to 5.1.1?
Since the upgrade, my phone's battery life has been terrible. There are a few other issues, but the main issue that others have experienced as well is the battery life. My wife has the same phone with the same issue.
This will not make a downgrade, but rather, fix your battery issues.
You have to clear the partition cache. Sometimes, with ota upgrade, old apps settings remains and cause trouble. You should not loose any data, but backup anything that worth it.
Make sure the battery is at least 50 percent and that the phone is plugged.
Shut down the phone. Restart it holding volume down + power. Hold both key for a while until you see a menu.
Press the volume key until recovery appears on the right and push power to select it
Wait until a green robot appears and by holding the vol up key, press the power button once.
A menu on the left will appear and using the volume down key, highlight the wipe cache partition and press the power button.
Wait until the end of the process then reboot phone.
