There are a number of factors that contribute to the poor battery life of your Android phone. Thinner housings, brighter screens, faster processors, more background software, and faster Internet connections put a strain on the phone's battery. For this reason, battery compartments and portable batteries have become increasingly popular.
Google added Doze with Android 6.0 Marshmallow This feature puts the phone in sleep mode when seated on a table, except for urgent notifications (eg text messages) and occasional syncs. With this battery optimization your phone will be charged automatically. However, you can take a few other measures to improve battery life.
Since this is true for Android, the options for activating these services vary depending on the handset. A quick search in the settings should call them.
Enable energy-saving mode
Do you think you are stuck in a situation where you need your phone Battery lasts longer than usual? Put your phone into sleep mode, which automatically disables features that may affect battery life.
For example, there are two options on the Samsung Galaxy S10 . The first option limits display brightness, CPU speed and network usage. The second option restricts your phone to the most important apps and services.
Samsung phones also offer device maintenance that eliminates crashed apps, bad data, and other contaminants that can expose space on your phone and consume energy.
Wi-Fi is your friend.
Your battery's network data is exhausting Disable the mobile data services in your phone's quick settings to prevent the phone from using cell phone data. You can also use airplane mode to disable all data network features and turn Wi-Fi on. This, however, interferes with incoming calls and SMS texts.
Take a break for the active pursuit.
Features such as Bluetooth, NFC, Samsung phone visibility, and location services are useful, but it helps keep the battery charged when you call the phone to connect and update. If you want to conserve juice, turn it off until you actually need it.
You may not always need your language assistant program. If you have google assistant working, go into wizard settings and deselect it. This prevents Google Assistant from actively listening and relieving the battery.
If you have a Samsung device, you can also turn off the Bixby voice The wizard feature that comes with the company's Android phones.
Your screen is too light.
Smartphones today look great with pigs. Your device probably does not need to be set to the highest setting. Enter the display settings and reduce the brightness of the screen. Your eyes and your battery will thank you.
You should also consider turning off automatic brightness, which adjusts to your perceived needs, but can also raise the brightness of your screen higher than it needs to.
You can also change how long your screen stays active. In your phone's display settings, set it to turn black after a few seconds. In the notification settings, you can disable notifications for specific apps so your phone does not light up each time a new notification arrives.
Rethinking Wallpapers and Widgets
 Keep away from moving wallpapers because your display needs energy to animate them. It's also a good idea to limit yourself to a background with fewer colors because the display consumes more energy when it has to render many different colors.
Widgets are tempting and practical, yet they are essentially active programs that can be used directly from your home screen. So the phone uses up energy to keep it running. Just say no to these little boys if battery life is a problem. 
Silence Your Phone
A phone that constantly beeps and buzzes with notifications is annoying and a battery is empty, so stop it.
Your phone needs to make an internal hum to an engine that, as you guessed, consumes energy. Go into the settings for noise and vibration and reduce the intensity of the vibration. You can also disable haptic feedback here so it does not vibrate when you tap or touch the screen.
Take control of your apps
Developers put in a lot of work is needed to make sure their apps run as efficiently as possible. Update your apps as often as possible to make sure you are using the best available version.
However, app updates can be quite extensive, affecting data and battery life. Therefore, it may be a good idea to restrict the updating of apps (and operating systems) to Wi-Fi updates. Or, temporarily turn off automatic updates until you can restore juice.
You can also disable automatic updates in apps. Your Instagram app may automatically be updated with new content as it becomes available. This is great for keeping up with your friends' selfies and holiday stories, but it's all – now! – a battery discharge. In your phone's settings, you can disable the option to automatically sync data and manually update those apps when you use them to extend battery life.
In the meantime, look for apparently ad-supported apps breaking batteries. As BuzzFeed reported in March, ad fraud programs can hijack in-app ads to run videos in the background. While you will not be able to see these videos, they will be registered as advertisements for the advertiser, which means you paid when your battery drops to zero. It is therefore a good idea to periodically check if there are outliers in the apps that unload the battery that you can erase.
Ask for a third-party app.
If all this is too much to remember, a service like If This Then That (IFTTT) supports automated workflows that can extend battery life. Use IFTTT to disable services such as Wi-Fi and Bluetooth based on your location, or disable certain services when the battery reaches a certain percentage.
Apps like Greenify meanwhile analyze the apps on your phone and determine which batteries are most likely to affect the life of your battery. Inactive apps that are considered to be problematic will be put into hibernation to ensure that your phone's battery is functioning as smoothly as it was the day you received it.
