How To Save The Battery Life Of Your Smartphone: The ability to fit larger batteries is one advantage of larger cellphones. Although battery life isn’t as much of a hassle as it once was, people still frequently worry about running out of power. We’ve compiled some battery-saving advice on what works and what doesn’t because most of the information available about how to prolong the battery life of your smartphone is outdated or questionable.
How To Save The Battery Life Of Your Smartphone
How to maintain your smartphone battery to make sure it lasts as long as possible and how to acquire a battery replacement when the time comes may also be of interest to you. Check out our guides on the best wireless chargers, best portable chargers, and best Apple 3-in-1 wireless chargers if you’re seeking for ways to keep your phone powered.
Turn on Power Saving Mode
Every smartphone has some sort of low-power mode that lowers or pauses particular tasks, features, and visual effects. When your battery is running low, these modes are perfect for preserving precious battery life, especially if it will be some time before you can reach a charger.
- Go to Settings > Battery and toggle on Low Power Mode.
- Add it to the Control Center via Settings > Control Center > Customize Controls and pick Low Power Mode.
- It turns off automatically when your battery is charged to 80 percent.
Depending on the manufacturer, the instructions for Android phones vary a little. There are typically two power-saving modes on Android phones. While the second is more drastic and disables notifications and the majority of apps, the first conserves battery life by restricting some activity and aesthetic effects.
- Go to Settings > Battery > Battery Saver and toggle on Use Battery Saver. You can also find it in Quick Settings when you pull down the notification shade (if it’s not there, tap the pen icon to edit and add it).
- Tap Set a Schedule on the Battery Saver screen to decide when it kicks in.
- Tap Extreme Battery Saver to decide when it should be triggered and tap on Essential Apps to mark any apps you want to exclude.
- It’s also a good idea to turn Adaptive Battery on in Settings > Battery > Adaptive Preferences.
- Go to Settings > Battery and Device Care > Battery to find Power Saving Mode.
- You can configure what it does on the Power Saving screen.
- It’s also worth tapping More Battery Settings to toggle on Adaptive Battery.
Reduce Screen Brightness For Battery Saving
You should set the screen brightness as low as is comfortable for your eyes because it has a substantial impact on battery life. Every time you swipe down to open the Control Center on an iPhone or the Notification Shade on an Android phone, you can adjust the screen brightness by sliding the Brightness slider. Another option to think about is automatic adjustment based on ambient light level.

Turn Off Always-On Display and Reduce Screen Timeout
It’s also a good idea to shorten the time the screen is on because it uses the most battery. Select the timeout that works best for you because the lowest value can be annoying.
- Go to Settings > Display & Brightness and set Auto-Lock to 30 seconds. Consider toggling Always On off.
For Android Phones
- Go to Settings > Display and set Screen Timeout to 15 seconds. Consider turning Screen Saver off.
- Go into Settings > Display > Lockscreen and ensure Always Show Time and Info is toggled off.
Prevent High or Low Temperatures
Your battery will suffer in excessive cold or heat. There isn’t much you can do about it, but try to stay away from things like leaving your smartphone in a hot car on the dash.
Locate The Source Of Your Battery Drain
If you’ve adjusted every setting we’ve mentioned so far and you’re still having trouble getting through the day on your battery, it could be worth looking into. You can see where the power is going by looking at the battery usage charts that come with smartphones.
- Go to Settings > Battery and scroll down to see usage charts of the past 24 hours or 10 days.
- If you select Last 10 Days and scroll down, you’ll see a list of apps. You can toggle between the battery percentage they used and the activity (which includes onscreen time and background).
- Go to Settings > Battery > Battery Usage and scroll down to see the apps and system functions that have been guzzling power over the past 24 hours. You can also tap on two-hour blocks in the chart at the top.
