A smartphone battery that drops quickly can become frustrating, especially when you have to charge your phone more than once a day. Sometimes an old battery causes the problem, but apps, display settings, mobile networks and other features can also increase power usage.
If your phone battery is draining fast, you do not always need to replace the battery immediately. A few changes in your phone settings can improve battery life and reduce unnecessary power consumption.
Here are some simple ways to stop your phone battery from draining fast on Android and iPhone.
1. Check Which Apps Are Using the Most Battery
The first thing you should do is find out which apps are consuming the most power.
On most Android phones, you can check this under:
Settings > Battery > Battery Usage
The exact option can have a different name depending on your smartphone brand.
iPhone users can go to:
Settings > Battery
You will see which apps have used the most battery over the last several hours or days.
Social media apps, games, navigation apps and video streaming services can consume more power because they use the display, internet connection, GPS and processor.
If an app is consuming unusually high battery even when you rarely use it, try updating it. You can also restrict its background activity or remove it if you no longer need it.
2. Reduce Your Screen Brightness
Your smartphone display can consume a large amount of battery, especially when you keep the brightness at a high level.
Reducing screen brightness is one of the easiest ways to improve battery life.
Instead of keeping the display at maximum brightness throughout the day, use automatic or adaptive brightness. This allows your smartphone to adjust the screen depending on the surrounding light.
You can also reduce the screen timeout duration. For example, setting your phone to turn off the display after 30 seconds of inactivity can prevent unnecessary battery use.
If your phone battery is draining fast, changing these two display settings can make a noticeable difference.

3. Turn Off Always-On Display if You Don’t Need It
Many modern smartphones come with an Always-On Display feature.
It allows users to check the time, notifications and other information without fully waking the phone. However, the feature still uses some battery.
If battery life is more important to you, consider disabling Always-On Display.
You can usually find the option under your phone’s display or lock screen settings.
Some smartphones also allow you to schedule Always-On Display. In that case, you can keep it active during the day and automatically turn it off at night.
4. Limit Background Activity for Unnecessary Apps
Some apps continue working even after you stop actively using them.
They may refresh content, check your location, download information or send notifications in the background.
Individually, these tasks may not use much battery. However, several apps constantly running in the background can contribute to battery drain.
Android phones usually provide options to restrict background battery usage for individual apps.
On iPhone, you can check:
Settings > General > Background App Refresh
You do not have to disable background activity for every app. Instead, focus on applications that you rarely use or that show unusually high battery consumption.
5. Use Battery Saver Mode
Both Android phones and iPhones include built-in power-saving features.
On Android, manufacturers usually call this Battery Saver or Power Saving Mode.
On iPhone, Apple calls it Low Power Mode.
These modes reduce certain background activities and other power-consuming functions to extend the remaining battery life.
Battery Saver can be especially useful when you are travelling or do not have access to a charger.
You can also configure some Android phones to automatically enable Battery Saver when the battery reaches a certain percentage.
6. Check Your Location Settings
Location services are useful for Google Maps, weather apps, ride-booking services and other applications.
However, not every app needs access to your location all the time.
Open your phone’s privacy or location settings and check which apps have location permission.
For apps that do not need constant access, change the permission from Allow all the time to an option such as Allow only while using the app, if available.
Also, remove location access from apps that do not need it at all.
This can reduce unnecessary background activity while also improving your privacy.
7. Poor Mobile Network Signal Can Drain Battery
Your mobile network can also affect battery life.
When you are in an area with weak network coverage, your smartphone may use additional power while trying to maintain or find a connection.
As a result, you may notice faster battery drain while travelling or staying in an area with poor mobile coverage.
If Wi-Fi is available and reliable, using it may help in some situations.
Similarly, if you are in a place with no mobile network for a long period and do not need calls or mobile data, Airplane Mode can prevent the phone from continuously searching for a signal.
8. Change 5G Settings if Necessary
5G provides faster mobile internet where supported, but network conditions can affect battery consumption.
If 5G coverage in your area is weak or constantly switches between 4G and 5G, your phone may consume additional power.
Many smartphones provide automatic network settings that switch between 5G and other networks depending on availability and usage.
If your phone battery is draining fast and you are regularly in an area with poor 5G coverage, you can test using 4G/LTE for a day and see whether battery life improves.
However, there is no need to permanently disable 5G if your phone already provides good battery life.
9. Reduce the Screen Refresh Rate
Many modern smartphones offer 90Hz, 120Hz or even higher refresh rates.
A higher refresh rate makes scrolling and animations look smoother. However, it can also use more power than a standard 60Hz mode.
If your phone provides an adaptive refresh rate, keeping it enabled can be a good balance because the device can adjust the refresh rate based on what you are doing.
Otherwise, users who prefer longer battery life can switch from 120Hz to 60Hz.
The difference can be useful if you spend several hours each day using the display.
10. Update Your Phone and Apps
Software problems can sometimes cause unexpected battery drain.
For example, an app may contain a bug that keeps it active in the background. Similarly, a system issue can affect battery performance.
Therefore, keep your smartphone software and important apps updated.
Android users can check for system updates through their phone’s Settings app. The exact location depends on the manufacturer.
iPhone users can go to:
Settings > General > Software Update
You should also update apps through the Google Play Store or Apple App Store.
However, immediately after a major system update, your phone may temporarily perform background tasks. Battery usage can sometimes appear higher during this period before returning to normal.
Other Simple Ways to Improve Phone Battery Life
Apart from these major settings, a few smaller changes can also help.
Turn off Bluetooth, hotspot or other wireless features when you do not need them for long periods. You can also reduce unnecessary notifications from apps that frequently wake your screen.
Using Dark Mode may help save some power on phones with OLED displays, especially when apps use truly dark backgrounds.
Avoid using live wallpapers if battery life is your main priority.
You should also avoid constantly closing and reopening every app. Modern Android and iOS systems manage memory automatically, and repeatedly reopening apps does not always save battery.
Why Is My Phone Battery Draining Fast Suddenly?
Sudden battery drain can happen for several reasons.
A recently installed app could be consuming too much power in the background. A software update, weak mobile network, navigation app or unusually high screen usage can also cause temporary battery drain.
If the problem started recently, check the battery usage page and compare it with apps you recently installed or updated.
Restarting your smartphone can also help if a temporary software issue is causing unusually high battery consumption.
If the problem continues for several days, you may need to investigate battery health.
Check Your Phone’s Battery Health
Smartphone batteries naturally lose some of their capacity as they age.
As a result, an older phone may not last as long as it did when it was new, even when your usage remains the same.
iPhone users can check battery information under:
Settings > Battery > Battery Health
Some Android manufacturers also provide battery health information, although the location and available details vary by device.
If your battery has degraded significantly, changing settings may improve battery life only to a limited extent.
In that situation, an authorised battery replacement may provide a better long-term solution.
Does Fast Charging Cause Battery Drain?
Fast charging itself does not mean your battery will immediately start draining faster after you unplug the phone.
However, heat can affect lithium-ion battery health over time.
Modern smartphones include charging and temperature management systems designed to protect the battery. Still, avoiding excessive heat is a good practice.
For example, avoid leaving your smartphone in direct sunlight or using demanding games for long periods while the device is already very hot.
Should You Charge Your Phone to 100 Percent?
You can charge your smartphone to 100 percent when you need the maximum possible battery life.
However, modern phones may also include features designed to reduce the amount of time the battery remains fully charged.
Apple offers Optimized Battery Charging, while many Android manufacturers provide similar battery protection or adaptive charging options.
Enabling these features can be useful if you regularly keep your phone connected to a charger overnight.
You do not need to constantly worry about the exact battery percentage. Avoiding extreme heat and using your phone’s built-in battery protection features is generally more practical.

When Should You Replace Your Phone Battery?
Not every battery problem can be solved through software settings.
If your phone is several years old and its battery drains quickly even with light use, the battery may have lost a significant amount of its original capacity.
Other warning signs can include unexpected shutdowns, unusually poor battery life or battery-related warnings provided by the operating system.
A swollen battery is more serious. If you notice the phone’s back panel lifting, unusual swelling or other signs of physical battery damage, stop using the device and contact the manufacturer or an authorised service centre.
Do not try to puncture, press or repair a swollen battery yourself.
How to Stop Your Phone Battery From Draining Fast
If your phone battery is draining fast, start by checking battery usage to identify which apps and features are consuming the most power.
After that, reduce screen brightness, limit unnecessary background activity, check location permissions and use Battery Saver when needed. Users with poor 5G coverage can also test a different network mode to see whether it improves battery life.
According to Google Android Help, users can improve battery life by adjusting settings, limiting battery-heavy features and managing apps that consume unnecessary power.
However, settings cannot completely fix an old or damaged battery. If your phone continues to lose charge unusually quickly after trying these steps, checking its battery health or getting the device inspected may be the next step.
For most users, a combination of sensible display settings, app management, software updates and good charging habits can help the phone last longer between charges.
