Checking Available RAM and CPU utilization on your Sony Xperia Xz2 Premium is very helpful if you are thinking about removing more Apps.

Looking at which Apps drain your RAM, CPU time, and battery will help you decide which of them should be removed from your phone.

To do this, just follow the simple steps below:

  1. Go to your phone settings. You can do this by swiping down the home screen to reveal the notification bar. From there, tap on the gear icon to open Settings.
  2. Look for Device Maintenance → Memory
  3. Alternately, you can also tap on “Data Usage,” then scroll down to see which apps are taking up CPU power.
  4. You may also look for “Smart Manager.” You will see the status of your RAM and Storage in this area. If you tap RAM, you will see a list of apps that are taking up much of your RAM.
  5. For Huawei users, you can look for “Storage” under Settings.

All methods from 2 to 4 can be accessed on the Phone Settings alone. There are certain variations, depending on your phone or unit.

This section should also show what is taking up valuable CPU time. Useful if you think some Apps are draining your battery.

To soft reset your phone press and hold the Power/Lock button for around 8 to 10 seconds. The phone will restart automatically.

If that doesn’t work, then remove the battery (if it has one). Wait 30 seconds and put the
battery back in. Then press the Power/Lock button to turn the phone on.

Some devices also provide reboot option on pressing Power Button.

If you tend to run out of battery power quickly, then you can turn on Power saving mode.

Pull down the notification screen by swiping your finger from the top of the phone. Then select Power Saving. You may need to scroll along the available icons.

You can also select to turn on Battery saver automatically, once battery reaches at certain level. To enable this, go to Settings – Battery – Battery saver, and then turn Automatic Battery Saver on.

If you call someone regularly this can be useful as you will have a shortcut to them handily placed on your homescreen.

To bookmark a Contact on your Home Screen, then first go into your Contacts App.

Find the Contact you want to add to the Home Screen and press on them.

Then press More or the Menu key and select Add shortcut to home.

Then go to your Home Screens, find the Contact you’ve just added. Press, hold and drag to another position.

If you like your Apps neatly sorted into folders, then there is a simple way to accomplish this.

First find the first App you would like in a folder. Then choose a second App. Press and hold on the second App and drag it over the top of the first App. They will both combine into a folder.

You can repeat this process to add more.

Once you have done this grouping, you can give specific name to that folder. For that just open the folder (containing different apps), and tap on Unnamed Folder tab and add your desired name.

Sometimes you may need your screen to stay on when plugged in via USB.

To do this, Drag down your notifications screen and press Settings. Then under System, select Developer Options. Then check Stay Awake.

If you can’t see Developer options then you need to enable this. Go to Settings – System – About device and press on Build number 7 times. Developer options will now appear in the System section of your settings.

To change the backlight screen timeout, drag down your notifications screen and press Settings. Then under System select Display. Then under Screen timeout you can set the screen time out duration.

You can also tell the phone screen to always stay lit when it is plugged in via USB. Go to Settings – System – Developer Options. Then check Stay Awake.

Note: Developer Options is not always enabled by default. To enable, go to Settings – System – About Device. Then tap on Build number 7 times to enable this secret option.

If you don’t want to hear the shutter sound when you take photos, then there are a few things you can try.

Firstly, some countries have laws to force the phone to play these sounds. Assuming you’re not in one of these countries, then the first thing you can try is to go to the Camera App – Settings – Shutter Sound – Off.

If that doesn’t work, then you can try turning the volume of the phone down or put it in silent mode when taking photos.

The last option is to Root your phone. If you don’t know what that means, then it’s best not to attempt it unless you have thoroughly read about the process. Once Rooted, go to this folder on your phone: /system/media/audio/ui and rename the camerashutter and/or cameraclick OGG files to something else.

Alternatively, on a rooted phone you can use a Root Browser, to edit /system/csc/feature.xml and set the option to TRUE. Then you should be able to go to Camera App – Settings – Shutter Sound – Off.

Android manages Apps very well and some Apps do not have the option to close them specifically. Normally the App will stay running in the background and only close when many other Apps have been opened.

If you do want to close or terminate an App, then press and hold the Multitasking key on your phone. On some devices you may need to long press the Home key. Then you can swipe the Apps off the screen to close them.

Even after doing that, there may be some apps still running in the background.

To close these apps, go to Settings and open Application icon, from here you can open applications list and tap on any app you want to close.

From here simply tap on force stop and application will stop working in background.

If you have forgotten your custom unlock pattern, then don’t panic.

After 5 unsuccessful tries a button should appear saying ‘Forgot pattern’. Press this and you will be asked to enter your Gmail username/password.

The phone will then ask for a new unlock pattern. If you don’t have a Gmail account, then you might have to either call your carrier or factory reset your phone.
