Here are a few ways to save battery life on your phones.
Enable battery optimization
Samsung devices come with a very handy tool that optimizes your battery usage. This function automatically closes any apps running in the background and checks if you are using any apps that are using too much battery power.
While Samsung will automatically optimize your battery once per day by default, you can do so manually to ensure the most battery life possible. Here’s how to use it:
Open Settings > Device Care > Optimize Now
If you’re not sure if Samsung automatically optimizes your battery once a day, you can check by selecting the three dots in the upper-right corner of this page, selecting Advanced, and turning on Auto-dark. optimization.
Other Android phones also optimize app usage by default. While you can’t run a generic optimization tool, you can check each app to see if it’s optimized and disable that optimization if you want in a few easy steps:
Open Settings > Apps > See all apps Go to the app you want to check, select Battery.
User can choose No Restriction (no optimization), Optimized (standard) or Limited (restrict battery usage even when the app is running in the background).
Set the application to sleep mode
On Samsung phones, you can put apps to sleep, which ensures they don’t run in the background when you’re not using them. Note, though, that it also means you won’t receive notifications or updates, which helps prevent these functions from draining your phone’s battery. However, Samsung warns that resting apps “may run in the background if you start using them again”.
If you absolutely don’t want idle apps to work in the background, you can put them into “deep sleep”. This option allows apps to work in the background only when you open them, and prevents them from continuing to work in the background even if you start using the app again.
While Samsung devices have a setting to automatically put apps to sleep when you haven’t used them for a while, you can also choose to manually put them to sleep. Just make sure you don’t put essential apps to sleep, like those you use for daily or work-related communications, as you won’t receive any notifications. from them.
To put apps into “break” and “deep sleep” you need:
Open Settings > Device Care > Battery > App Power Management. On Put unused apps to sleep so your phone can automatically put less used apps to sleep mode. Select Sleep apps to manually put the app to sleep when it’s not being used frequently. To add apps, tap the Plus icon in the upper-right corner of the screen.
Select the app you want and tap Add. You can remove an app from the list by selecting the ellipsis icon in the upper-right corner of the screen and selecting Remove. Once you’ve finished selecting the app, select Delete again. Follow the same steps above to add or remove deep sleep apps and add or remove apps from Apps that won’t be put on the break list.
Other Android devices like Google Pixel use Doze mode. This is a similar function introduced in Android 6.0 to ensure that your apps don’t use battery when you’re not using your phone. This mode is activated automatically when the phone is unplugged and idled for a certain period of time, so you don’t need to do anything.
Enable Battery Optimization and Adaptive Brightness
Battery Optimization and Adaptive Brightness are two battery-saving features that use AI to scan how you use apps and the screen and adjust them to the owner’s habits. You should have both enabled by default and they don’t need to be checked.
To enable Battery Optimizer mode:
Open the Settings app and select Device Care > Battery. Select Application Power Management and make sure that Adaptive Battery is enabled. If you have a Pixel or a non-Samsung phone, the process is the same as this: Open the Settings app and select Battery > Battery Optimization Options Make sure Battery Optimizer is on.
Note: After activating Battery Optimizer mode, your phone will remember the setting, and although Battery Optimizer may be turned off, your phone will still perform it silently without is there a way to reset the tool. So, if you have a problem with a certain app (slow notifications for example) and you suspect Battery Optimizer mode might be the cause, the only way to solve this problem is to do a reset. entire phone.
To enable Adaptive Brightness:
Open the Settings app and select Show Find and tap on Adaptive Brightness to enable the feature if it’s not already on. Other than Battery Optimizer mode, Adaptive Brightness can be easily turned off completely.
Use apps that help save battery
There are a number of apps in the Play Store that can help you with battery saving, and many of them are really effective, most notably AccuBattery and Greenify.
AccuBattery measures your battery usage over time and lets you catch any deterioration. The application also provides information when the battery is fully charged or activates the charging mode so that the device does not reach 100% (because many people believe that charging the battery to 100% will accelerate the battery’s degradation process). In addition, AccuBattery can also estimate how much time is left before it runs out of power, depending on how you use your phone.
Unlike AccuBattery, Greenify allows you to force apps to hibernate (whether they want to or not), saving you from unwanted battery drain.
Disable or uninstall unnecessary apps
It’s always a good idea to periodically check all the apps you have to remove or limit any that are using your battery unnecessarily.
The first is the easiest: go through your app drawer and see if there are any apps you don’t recognize (because they’ve been sitting in there for so long) or you find annoying. Instead of letting them consume energy and memory, you can simply uninstall them.
You should also find out which apps are using the most power. On many phones (including some Samsung models), you can find out which apps have been draining your battery in the last 24 hours by going to Settings > Battery > Battery Usage. But you can also test individual apps. (Note: these instructions are for Samsung Galaxy Note 9 phones; your phone may behave slightly differently.)
Go to Settings, select Apps, then tap an app that you think is consuming a lot of your battery. Below Battery, you can see the percentage of energy an app has used since you last charged your phone. If you see an app using a lot of power, tap Battery. Turn off Allow background activity to prevent apps from working in the background. (On some non-Samsung phones, you can select Restrict to do the same thing.) From the same page (on Samsung phones), you can also adjust battery usage for all apps. your usage by tapping Optimize battery usage. Here you can choose to optimize the battery usage of each app. Of course, enabling the Optimize battery usage option will limit some app functions to save battery.
Use battery saver mode
You can enable power saving mode when the battery level starts to get low. The Samsung Galaxy Note 9 offers several different options depending on how much battery you want to save (note that these options may differ from other Android devices):
Maximum battery saver mode saves the most battery. It blocks apps from using your data or location in the background, turns off Always On Display, and uses dark mode with a simplified home screen. Medium battery saver mode blocks apps from running in the background and disables Always On Display mode. Optimized as a setting I use every day, this mode gives you a “recommended balance of performance and battery life.”
High performance is something you should not use if you are trying to save battery, as it uses maximum screen brightness and resolution.
Here’s how to change the battery mode on your device:
Go to Settings > Device Care > Battery. Select Battery mode and select the mode you want to enable. You can also let the device automatically select your phone’s power mode based on your usage by enabling Adaptive Power Saver mode.
On other Android phones, you can use Battery Saver to do much the same thing, although it only has a single mode:
Go to Settings > Battery > Battery Saver. Use Scheduler to decide if Battery Saver will work based on your habits or percentage of remaining power. You can also choose when to turn off Battery Saver. If you find yourself running low on battery and you have no way to charge it, Extreme Power Saver (also on this page) will shut down all but essential apps. (You can decide which apps qualify as “necessary”.)
If you want to manually enable or disable battery saver mode, you can also do it here, but there is an easier and faster way. There will be a Power Mode (or Power Saver) icon in your Quick Settings drop-down menu on the home screen.
If you don’t see it right away, look for the three-dot icon in the top right corner and tap the Order button. You’ll see all the icons that you can place in your Quick Settings menu; just tap and tap to move the Power Mode icon upwards. For me, turning on Power mode turns on Medium Battery Saver mode and turning it off switches my device to Optimized mode.
Save battery in case of emergency
Sometimes, despite all precautions (even with power saving mode on), your battery percentage keeps dropping, you have no way to charge your phone but still need enough battery to receive phone calls or messages; some of the following may be helpful, although some of them may interfere with normal use:
Make sure all your apps are off. Turn on Do Not Disturb mode to stop notifications. Set your screen timeout to 30 seconds so the screen won’t light up if you’re not actively using it. Reduce screen brightness as much as possible. Turn off Bluetooth, location tracking, and Wi-Fi (unless you’re using it).
You can also use Airplane Mode unless you’re waiting for a phone call or texting. Turn off the notification light if your phone has one. Turn off all your app sounds and vibrations. If your phone has an OLED screen, using dark mode can help save power.
