Battery saving tips. How to save battery on Phone or Tablet ?

Hi, how can I save battery on Android mobile phone or tablet ?

What are the best battery saving tips ?

To save battery on your phone or tablet, you have to reduce the using of its hardware, like display, Wi-Fi, GPS, bluetooth, speakers, vibration motor, CPU etc. You can reduce the using of device's hardware manually, but there are also some battery saving modes and battery saving apps available.

Battery saving tips:

• Reduce screen brightness - it is one of the easiest ways how to prolong your battery life.
• Let the screen turn off sooner
• Enable Dark Mode - you can try to use dark theme.
• Set the brightness to change automatically - it is a comfortable way how to get enough brightness.
• Turn-off Wi-Fi, Mobile data, GPS, Bluetooth, NFC - disable these hardware parts when you don't use them.
• Turn-off vibrations
• Turn-off keyboard sounds
• Enable data saver for mobile data
• Try to use Power Saving Mode or Battery Saving App
• Disable display high refresh rate - turn off smooth display feature if active.
• Close unused applications that are running in the background

If you often wake up your phone for example to check time or notifications, you can also save battery with using of "Always on Display" mode. It lets you view the time, date, missed calls, notifications or other information when the screen is turned off. With Always on Display you don't need to wake up your phone so often. The feature is also called Active display or Ambient display.

When you are in a low network signal area and you don't need to use your phone, you can turn on the Flight mode to save battery. Low network signal usually drains battery faster, because phone is using more power to communicate to cell towers.

After you activate Flight mode, the phone will stop communicating with cell towers, so you will be not able to make or receive calls, messages and also use mobile data.

To save battery on your Android phone or tablet, you can download and use one of the battery saving apps. Some of them are available for free.

Battery saving apps can identify the battery draining apps and let you simply disable them. In some apps, you can use the pre-set battery saving profiles.

In the recent Android versions, you can enable the Power saving mode to save the battery. This mode can limit the CPU speed to 70%, decrease the screen brightness by 10% or limit apps and Home screen.
The Power saving mode is available in:
Settings > Battery and device care > Battery

You can also set the Background usage limits. This feature limits battery usage for apps that you don't use often. It can put unused apps to sleep. You can find it in:
Settings > Battery and device care > Battery > Background usage limits

You can check which apps in your phone drain the battery the most.

Go to Settings - Device care - Battery - Battery usage

In these previews, you can see the list of the most battery draining apps. You can see the Screen on time, percentage and how many minutes were apps actively used and how many minutes they were running in the background.

These informatiom can be sometimes really interesting. You can find out which apps drain your battery a lot while running in the background. I have found out that some battery draining apps are running in the background, but I don't use them.

In the "Last 7 days" preview, you can check which apps drain your battery on each day.
