Android M.

First off is doze mode.

Now doze mode effectively is going to

help save your battery life. Now Google are claiming up to a four times improvement

in battery life by using this technique. Now what this basically means is

the apps that you currently have on your Android device tend to

have the ability to do things in the background including updating themselves.

Now that's good for a certain group of users if you need

your data to be fresh on your device every time you pick it up. But for those people who are

looking to

extend the battery life of your smartphone that can be a bit of a

problem. Now the idea behind doze mode

is it will selectively put apps to sleep and

by putting them to sleep it will actually put them to sleep. They will

only wake

up if they have to receive a high-priority message which you yourself

are able to

obviously toggle on or off as you need to. Now you can set doze mode on an

app by app basis which is very, very useful. I think this is probably going to be the

big change really in Android and that the majority of users are

going to notice. Purely because everybody notices battery life.

If Google as claimed are able to increase standby time by up to four times

the current benchmarks then that is a major benefit all round for everybody.
