How to control Dozing apps
Doze is a new feature designed to significantly increase your battery life by putting your device to sleep when it has been idle for a certain amount of time. You will still get notifications if the developer of the app enables it, though. For example, Gmail and Hangouts will still showcase notifications when in Doze mode.
That’s all fine and dandy, but there might be another app that’s important to you, one you want to see notifications from even while in Doze mode. To enable the feature, simply open Settings and select Battery. Then, tap on the three dot menu in the top-right corner, select Battery Optimization, and tap Not Optimized before selecting All Apps. You can now select the apps that you don’t want optimized for Doze mode. Keep in mind, doing so will hurt your battery, so only do it for the apps that are really important.
How to see what apps are using the most memory
Sometimes your device might run slow for no reason. Now you can tell what apps are using the most RAM on your device with a new feature called Memory. Just open Settings and select Memory. You’ll be able to see the average memory used during the last three hours, six hours, 12 hours, or the entire day. You can also tap Memory Used By Apps to find out how much RAM each app has used. This can help you to pinpoint any apps that are using too many resources.

If you’re a frequent user of Google Translate, you’re going to love this new feature, exclusive to Marshmallow. Assuming you have Google Translate installed on your device, just select the text from any app that you want to translate, and selectTranslate from the copy-paste popup menu. This means you no longer need to copy and paste the text, or open Google Translate separately. This should work with any app that has the standard Android text selection enabled.
How to use direct sharing
You’re likely already familiar with Android’s sharing menu, one in which you can can share information from one app with a number of different apps. With Marshmallow, Google has implemented the ability to use this same sharing menu to share content with other people. This means if you want to send a picture to a friend, you merely tap Share while looking at the picture and select your friend’s Hangout conversation to do so. This is much easier than sharing it via the official Hangouts app. Sadly, there are no apps that currently support the feature, but we expect developers to jump onboard quickly.
Play a the Flappy Bird clone Easter Egg
Google throws in a cool Easter Egg with every version of Android, and Marshmallow is no exception. This year’s surprise is similar to last year’s Lollipop Easter Egg in that it’s a Flappy Bird clone, one in which you must navigate a sea of marshmallows instead of lollipops. You can now add up to six players as well.
To open the game, just open Settings and tap on About Phone. Now tap Android Version rapidly until you see the Marshmallow “M” icon appear in the center of the screen. Tap it once and it will change to a picture of a marshmallow with antennas. Now tap that icon repeatedly — or, at least three times — and follow it up with a tap and hold.
How to customize the Quick Settings menu
The Quick Settings menu that appears when you swipe down with two fingers from the top of the display is awesome, but it’s even better when you customize it. Thankfully, Google finally added the ability to do so with Marshmallow, but you would never know how unless you know the trick to unlocking the System UI Tuner.
To do this, just tap and hold the Settings icon in the top-right corner of the Quick Settings menu. After a few seconds, lift your finger and you will see a popup at the bottom telling you that the System UI Tuner has been added to your Settings.
Now, tap on System UI Tuner from the main Settings page (it should be at the bottom) and tap on Quick Settings. From here, you can tap and hold any of the tiles to move them around or remove them from the menu. There is also an Add Tiles option if you want to add tiles that you may have previously removed.


How to display the battery percentage in the status bar
It’s nice to be able to see how much battery life you have left in the status bar, but many people prefer to see it as a percentage rather than the “cup of water” method. You can do this from within the System UI Tuner that we enabled in the previous tip. Assuming it’s already enabled, just tap System UI Tuner from the mainSettings page, followed by Show Embedded Battery Percentage. Doing so will toggle the feature on.
How to silence your phone with the volume button
This almost doesn’t even seem like a tip because it’s an obvious function, but it wasn’t as easy to silence your phone with Android Lollipop. Thankfully, Google has brought back the ability to silence everything — aside from alarms — by simply turning the volume all the way down.
