More and more Android phones are being shipped or updated to Android 6.0 Marshmallow, and with that, new issues are being found weekly. One of the new major issues is the battery draining quickly when connect to Wi-Fi. This is affecting all device but if it is affecting yours and you are at your wits end, great news, we have found a fix! If you follow the steps outlined below, you will be able to fix the issue too.

You have now reduced the power consumption Wi-Fi has on your battery. If you ever want better GPS Just go back into your location settings and change it back to High accuracy. If Android ever pushes out an update that corrects the battery drain when on Wi-Fi then you can just undo everything you did and be back to normal with great battery life again
I should mention the results will vary, but there is no harm in doing any of these steps.
