One of the improved features of Android 6.0 Marshmallow is improved battery life. Be it the Doze mode or the polishing of the rough edges of its predecessor, most people – at least the reviewers – seem to be noticing that their devices aren’t as thirsty for juice as they once used to. Unless you have a Nexus 5 or 6 that is.
I finally switched back the Nexus 5 couple of days ago and I immediately noticed how fast the battery of my phone drained. Today at work, I was down to the 30%s in no time. When I checked the battery status from the settings app, I notice something weird. The item that was using the highest percentage of battery was Wi-Fi. Why it is weird is because I did not have Wi-Fi enabled while I was away from work. So how could the Wi-Fi feature be responsible for draining the battery.
Google search – ironically in this case – came to my assist. It appears that there is a feature called Wi-Fi scanning in Marshmallow which helps improve the location by letting system apps and services detect Wi-Fi networks any time. I am not sure if it really helps with anything, but all I know is that I am not getting my whole day battery life anymore.
