The recently launched Samsung Galaxy S7 and S7 Edge have been getting massive critical acclaim for their incredible battery performance, speed, and cutting-edge features.
How to stop your Samsung Galaxy S7 from draining too fast? Turn off all the functions you don’t need, reduce your screen brightness, use the power saving mode, reduce background data usage for apps, uninstall unused/faulty apps, install the latest software/app version, clear the cache for both the apps/device, make sure the charger/outlet you are plugging it in is not damaged.
Some of the Galaxy S7 battery drainage reasons may seem a tad bit too simple, but they are the true perpetrators, especially when your phone is new.
Why Is My Galaxy S7 Battery Draining So Fast?
Battery life relies on various factors, including capacity, usage time, version, and apps installed. These are the main causes that affect the operating time.
- Load And Usage Frequency
If you use your phone a lot, the battery will quickly lose power. But the operating time also relies on the load.
If the load (apps used) is high, such as with movies, mobile internet, and games with heavy graphics, the battery drains in a few hours.
If the load is optimal, such as with books, conversations, SMS, and music, the battery lasts longer.
- Glitches In The Operating System
With time, glitches and bugs appear in the operating system. The reasons vary; for example, the user installed low-quality apps, incorrectly updated the firmware and uninstalled them incorrectly, or didn’t clear the unused and old files from memory. The more bugs/glitches there are, the quicker the battery drains.
- Quality And Number Of Installed Applications
The more apps you install on your Samsung Galaxy S7, the faster your battery will run out. The quality of poorly made applications also strongly influences the battery, as they constantly load the processor and keep the device going into sleep mode.
- Cellular Signal
The quicker the battery runs out, the worse the cellular signal. This is because the transmitter of the smartphone is forced to work at a higher power to maintain a connection to the network.
- Battery Status
The battery usage capacity decreases with time. The older the battery, the lesser charge it carries.
- Wrong Charging Methods
If you use an adapter or a charging cable that Samsung does not officially brand, it can cause a phone’s battery to quickly run out. The phone only charges best when used with the accessories provided by the company.
How Do I Stop My Galaxy S7 Battery From Draining So Fast?
To recognize the application causing energy drain from your mobile device, let’s check that the problem is not linked with the hardware. Use the mobile device in Safe Mode.
1.Scan For Problems
- Click on the power button and choose the “Switch Off” option.
- When the phone is off, press and hold the “Switch On” button for 2 seconds.
- When you see the Samsung logo, press and hold down the “Volume Low” button.
- You will see the word “Safe Mode” in the lower-left corner of the screen if the process is completed successfully.
- Now you can use the phone and see if the battery timing improves. If you only notice a change in battery timing by 15-30 minutes, it might be a problem with the phone’s battery health, and you will have to replace the original battery.
- Still, if the battery timing gets better and increases by up to 40 minutes, the main problem causing the battery drain is the corrupted software, and you can solve the problem by booting your phone out of Safe Mode.
2.Recalibrate the battery
In some cases, this step alone can be quite effective at tackling the problem of the phone’s battery draining too fast.
- Discharge your phone fully until it turns itself off.
- Turn it on again and let it turn itself off.
- Plug your phone into a charger and, without turning it on, let it charge until the screen says 100 percent charged.
- Unplug your charger.
- Turn your phone on.
3.Clear the Cache
This is a pretty common culprit that can make your phone’s battery work significantly worse, especially if you don’t have a habit of clearing your device’s cache from time to time.
- Press and hold the Power button, select the Switch Off option.
- Hold the Home button and Volume Up button simultaneously, then press and hold the Power button too.
- When you see Samsung Logo, release only the Power key.
- When the Android logo screen appears, release all the keys.
- Press the Volume Down key until the Wipe Cache Partition is highlighted
- Press the Power key to select the option and restart your device.
4.Delete Malfunctioned Apps
After recognizing that the issue originally lies within the applications, choose the applications that use a whole lot of battery and remove them.
- Drag down the notifications bar and choose “Settings” from the drop-down menu.
- Within “Settings,” click on the “Battery” option and tap on the “Battery Usage” option.
- Within the details of battery usage, identify an app that is using a lot of battery power.
- Delete the app if it is not one you use regularly.
- Observe if the battery drainage has stopped.
- If the problem persists, try to delete more apps that consume a lot of battery.
- If the problem still exists, try the 3rd solution.
5.Restart Your Phone
If your battery problems were caused by either some software or charging issues, this simple step will help you. Just make sure to restart your phone from time to time to eradicate the minor glitches.
6.Check For App/Software Updates
If some of your apps or your software version are not updated, they drain the battery by consuming more power than needed. Thus, in this step, we recommend you check for updates for all your installed apps and apply them if the latest versions are available.
- Unlock your phone and go to the Google Play Store.
- Tap on the “Menu” button on the top left corner and choose the “My Apps & Games” tab.
- Click on the “Updates” tab and choose the “Refresh” icon.
- Choose the “Update All” option and wait for the apps to be installed and updated.
- See if the issue (battery drain) persists.
To check for the software updates, do the following:
- Go to your phone’s Settings.
- Find and click the About Device option.
- Click on Software Update.
- Select the Check for Updates option.
- Download the updates if there is any option available.
How Long Do The Samsung S7 Batteries Last?
The Galaxy S7 battery can last up to 9 days and 10 hours if no activity or operation is performed on it. Because of the 3,000 mAh battery, the battery life can reach up to 10 days and 2 hours. The standby time in the phone is called the Snapdragon version. In the Exynos version, the battery can last for 10 days and 2 hours.
Considering both versions of the Samsung S7, with the Exynos version, the battery has a 10-20% better life. The Samsung Galaxy with the Snapdragon version also has good battery life, but it does not last as long.
When both versions are used non-stop, the phone’s battery can last up to 6 hours. So, you can use your Samsung S7 for 6 hours maximum. This includes music, browsing, playing games, and using the camera.
Can A Samsung S7 Battery Be Replaced?
Yes, you can easily replace your Samsung S7 battery by following these steps:
- Power off your smartphone.
- Remove the sim card tray.
- Put a suction cup on the backside glass of the phone.
- Use a heat plate or heat gun to soften the adhesive material across the corners of your Galaxy S7’s back cover.
- After removing the back cover, use a screwdriver to remove the screws keeping the rear house fixed.
- After removing the screws, detach the center, top, and lower plastic modules. After their removal, you will be able to see the battery.
- For proper removal, you must unlink the battery flex cable.
- Then, soften the adhesive material by using the spudger to lift the battery carefully. Don’t puncture the battery.
- After removing the malfunctioned battery, put the new battery into the phone with great care.
- When you reconnect the battery flex cable, repeat step 7 in reverse order.
Battery replacement is a time-consuming and complicated process and demands professional assistance. As the disassembly of the phone is complex, we strongly recommend you seek help from a professional phone repair service.
