These days we rely on our phones more than ever, which makes it a real bummer when your battery runs out. When that happens, you may find yourself wondering, "Why is my Samsung battery draining so fast?" If your Galaxy device is struggling to make it through the day, here are some practical ways you can cut down on your energy usage.
1. Adjust Your Samsung Galaxy Display Settings
Long screen time-out settings can significantly reduce your battery. By adjusting your settings to turn your screen off sooner, you can help cut down on the amount of power that you're using. To change this, go to "Settings," then "Display." Touch "Sleep" and reduce the amount of idle time before your phone goes to sleep.
2. Lower the Brightness Setting on Your Cell Phone
The brightness setting on your device is something you probably don't think about very often, but it can have a real impact on how long your battery holds a charge. Reduce the brightness by pulling down the "Notifications" menu and using the slider to select a lower setting.
3. How to Turn on Dark Mode on Your Samsung Galaxy Phone
Enabling "Dark mode," will turn your phone's background to black. This reduces the amount of energy your phone screen is using and helps the battery to last longer. To enable this, simply open up "Settings," then turn on the "Dark mode" icon. You can also schedule Dark mode to turn on at specific times. To set a schedule, go to "Settings," "Display," then "Dark mode settings."
4. Turn on Power Saving Mode
"Power Saving Mode" will differ slightly between different devices. In general though, "Power Saving Mode" will close all unnecessary screens and apps to help cut down on needless power usage.
5. Check Your Device's Sync Settings
Frequently syncing your phone drains your battery much faster. Check the sync settings on your apps or email to make sure they only sync as often as you need them to.
6. Turn Off Your Mobile Data Usage
Using mobile data in areas with a low signal uses a lot of battery power. If your battery is running low and you don't need your mobile data, switch it off.
7. Update Your Galaxy Device to the Latest Firmware
Is your device currently running with the most recent software? If not, be sure to update it as soon as possible to help it run more efficiently.
8. Turn Off Wi-Fi, Bluetooth and GPS on Your Device
Wi-Fi, Bluetooth and GPS all regularly check for a signal, which uses battery power. If you aren't using these applications, turn them off.
9. Close Apps When You're Done Using Them
It's easy to mistakenly leave apps running in the background, but this wastes battery power, especially in the case of GPS enabled apps. If you want to keep them from draining your battery, close them after you're finished using them.
10. Minimize Your Phone's Exposure to Hot and Cold
Extreme heat can cause your phone to overheat, while cold can lead to unexpected shutdowns. Try to avoid using your device in extreme temperatures. There are also a number of ways to cool down a phone that's overheating and keep your device from dying in the cold.
11. Check Your Galaxy Charger
If you're having issues with your battery's performance, check the amperage of your charger. Does it match the amperage of your device? If not, you'll want to pick up a charger that's more compatible with your model phone or tablet.
Additionally, the way you charge a device can have a serious impact on its battery life. Be sure to avoid letting your battery run all the way down as this can harm it. Ideally, you should never let your battery discharge below 20%.
12. Replace Your Cell Phone Battery
If you've tried everything above and you're still experiencing issues, it could be due to a bad battery. Cell phone batteries typically last between one and three years. After that, they have a hard time holding a charge. If you think your battery might be dying, bring it to your nearest Batteries Plus and have it tested for free.
