Why does my phone battery run out quickly even when fully charged?

The bigger the battery, the more power your device can get, but battery life is still something that most users care about. This is a big deal for modern technology, but that doesn't mean you should plug your phone in multiple times a day. If your phone's battery is draining faster than usual, here are some possible causes and solutions.

1. Screen

The screen is the biggest battery hog on today’s smartphones. Panels are getting bigger, brighter, and more colorful. Now we have large foldable screens and dual-screen devices. While these improvements greatly improve the overall user experience, they also drain more battery than ever.

How to check battery status:

1. Open the Settings app .
2. Select Battery .
3. Click on the 3 ellipsis menu in the right corner of the screen.
4. Select Battery usage .
5. Click on the 3 ellipsis button in the right corner of the screen.
6. Select Show full device usage .

When you check your battery usage, you will see that the screen accounts for a very large percentage. Display technology is developing at a rapid pace, much faster than battery technology, which leads to battery life becoming a burden in the future if it does not keep up with technological developments.

Tips to reduce battery drain due to screen:

• Reduce screen brightness : Reducing screen brightness can help save battery life a lot.
• Use auto-brightness : This feature helps you have a bright screen only when needed, saving battery when not needed.
• Reduce screen auto refresh : Some devices have high screen refresh rates and you can customize these settings.
• Reduce the number of times the device locks itself : Lock the screen immediately after use instead of waiting for the device to lock itself, this will help you save a lot of battery.
• Don't use animated screens : Animated screens can be nice, but you don't have to use them all the time. Animated screens are a huge battery drain.
• Use a black screen : If your device has an AMOLED display, a black screen saves the most battery because it doesn't have to activate as many pixels. The difference isn't huge, but every little bit adds up.
• Take advantage of the small screen : Some phones like the Samsung Galaxy Z Fold 2 have a small screen on the outside of the device. Use these screens often, when you don't need the big screen.

2. Poor connection

Areas with poor cell signal are silent battery killers that are even more annoying than a video that won’t load. Your device will constantly be communicating with nearby cell towers, trying all the time to connect. Sometimes these attempts fail, and your phone will have to work harder to get you to use your device.

If you live in a remote area or in a large building, your phone battery life will probably be much worse than other people's.

How to improve signal to reduce battery drain:

• Switching Carriers : Your carrier's signal will depend on the area and city you live in. Do your research and find out which carrier has the strongest signal in your area and stick with that carrier.
• Airplane mode : Airplane mode is a feature that forces your phone's antenna to stop working. It turns off all connections so your phone doesn't try to connect anymore. You can use this method when you're in places with poor signal. You can also use smart tools like IFTTT to automatically turn on airplane mode based on your area.
• Network extenders : Carriers often have network extenders that use the Internet to provide you with a signal. Consider getting one if you're going to be in a place with poor signal for an extended period of time.
• Signal boosters : Signal boosters can be quite expensive, but many people are willing to pay for them. These products usually have an external antenna to pick up the signal.

3. Background applications and services

Check your apps if you notice your battery draining too quickly. Some apps use more power than others, typically streaming services like YouTube, Netflix, etc. You can avoid playing games a lot if you want to save battery because they will be extremely battery-consuming, especially games with beautiful graphics.

There are many apps that drain your battery without actually being used. Apps like Facebook, Messenger, Instagram, and WhatsApp are examples of these. Chat services like these are always running to keep up with the latest information. This means that these apps are constantly running in the background, using data, location, sending notifications, etc. Not to mention that you often spend a lot of time using them, constantly checking for new information.

How to solve the problem

• Download as few apps as possible : Most people only use 20% of the apps on their devices at any given time. These apps often run in the background and drain your phone's battery. Clean up your data and delete unnecessary apps.
• Prevent apps from running in the background : If you find that an app is using too much battery, you can limit its activity. Go to Settings > Apps & notifications > Select the app > Advanced > Battery > Background restriction > Restriction . However, this restriction will make some features unavailable.
• Closing apps : Android devices are designed to multitask and closing apps can be a bit disruptive to your workflow. However, sometimes closing apps is the best option. Sometimes apps aren’t working properly, which can cause your battery to drain quickly. Go to Settings > Apps & notifications > Select the app > Force stop .
• Use smart, use carefully : Sometimes you want to have longer battery life but playing games, watching movies and spending hours surfing the internet is the opposite of that desire. So use your phone smartly to avoid the situation of the phone running out of battery when you get off work.

4. Age of the phone

How old is your phone, and more specifically, how old is its battery? Smartphone batteries degrade over time. In fact, time is the main reason your battery life is getting shorter. Older phones also don't perform as well as they did when they were new.

Solution:

• Buy a new phone : It may sound obvious, but the truth is that when the battery is too old, the functions will no longer work effectively. You are the one who understands best the problems you encounter on your device.
• Replace the battery : For devices with removable batteries, replace the battery with a new one. Devices with built-in batteries can also replace the battery by removing the device and replacing it with another battery, but this will pose more risks. You can go to a warranty or repair facility to replace the battery.

5. Picture-in-Picture mode

If you use YouTube Premium, Twitch, or a similar app on your phone, you may have used Picture-in-Picture mode before. This involves watching any video or stream in a small viewing box on the screen while using other apps. While this is convenient, using multiple apps at the same time can drain your phone's battery.

So you can disable Picture-in-Picture mode by going into the advanced settings of the app you selected and turning off the Picture-in-Picture option.

6. Stay connected 24/7

People often keep WiFi or data enabled at all times so they can stay connected day and night. But this can drain your phone's battery significantly, as you're constantly getting notifications, background updates, etc. when you don't necessarily need them.

Bedtime is a great time to turn off WiFi. Of course, you can just put your phone on airplane mode. However, if you're worried about missing an urgent call, you can instead turn off WiFi and data so you can still accept phone calls. You can do this by going to your phone's WiFi and mobile data settings and turning both off. Keep in mind that putting your phone on "Do Not Disturb" mode won't turn off WiFi or data.

7. Location tracking application

There are lots of apps that can track your location. Google Maps, Bumble, Deliveroo, retail apps, etc. And, while you might think that these apps only track your location when you’re directly using them, this isn’t always the case. This constant location tracking requires power and can affect your phone’s battery life. So how can you avoid this?

The easiest way to disable location tracking is to turn off your phone’s location entirely. This can be done in the phone’s drop-down menu or in Settings via the Location option. However, if you want certain apps (perhaps safety or navigation apps) to continue tracking your location, you can turn off location tracking individually through the Permissions section of each app’s settings. Doing so may take a little time, but it will give you full control over which apps do and do not have access to your real-time location.

8. Other battery issues

• GPS, Wifi and Bluetooth : Do you use these features often? GPS, Wifi and Bluetooth always drain battery, even when used sparingly. Turning them off when not needed will save a lot of battery.
• Camera : Taking photos and recording videos consumes a lot of battery. If not necessary, you should not use this feature too often, especially third-party photo and video recording applications.
• Temperature : Actually, low temperatures affect battery life quite a bit. Keeping your phone too cold is very harmful to the battery, so the best way is to keep your phone with you to keep the temperature stable, especially if you live in a cold country.
• Software updates : Software updates will help improve battery life, so update regularly to the latest operating system version.
• Buy a reputable charger : A good battery charger will protect the battery, help it work better, and "live longer".
