[Update]: Sudden battery drainage and overheating issues? Try this fix first.

Samsung launched its latest Galaxy S7 and Galaxy S7 edge earlier this month. This year’s impressive Galaxy S7 duo is among the best Android smartphones that you can get. But, with all the shine and glamour also come the regular issues. One of the most talked-about and possibly most annoying problem that you can have on your Samsung devices is the battery drain. Several users have confirmed the battery drain problem on Samsung’s Galaxy S7 and S7 edge. However, you can easily fix Galaxy S7 battery issues as most of the times it’s about a bad app or some other services running unnecessarily in the background, more than a problem with the device itself.

Samsung has employed a massive 3,000 mAh battery pack in its Galaxy S7 and a bigger 3,500 mAh in its Galaxy S7 edge. For comparison Galaxy S6 has a 2,550 mAh battery pack, while iPhone 6s Plus flaunts a 2,750 mAh battery. Which means that your phone should ideally be able to last you longer than previous Galaxy devices. Still not happy with the battery life? Follow this post for a detailed checklist to see if you are missing out on some important aspects of your new smartphone that could help you get more battery life.

Here are some of the tips to help you fix Galaxy S7 battery issues, which will also work on Galaxy S7 edge. Many of the following tips and features will help you get more life from your other Android smartphones regardless of their manufacturer.

– Turn off Briefing:

Samsung Galaxy S7 and Galaxy S7 edge bring an app called “Briefing” out of the  box. When you swipe left on the homescreen, you will see this app curating info from multiple sources to get you everything at one place. It may sound like a useful feature, but it’s often very laggy. Not only is using Briefing a pain in itself, but also affects battery life (and for some users, performance issues) on your Samsung device.

Our suggestion? Disable it! You can use Flipboard’s Android app or any other similar apps offering way better functionality and services.

  • To disable Briefing, long-press on a blank spot on the homescreen.
  • Now, swipe over to the left which will take you to Briefing > turn it off.

– Close unnecessary running apps:

There are many apps running in the background, even when you don’t use them. Find out these and close them. Some messed up third-party application (read: Facebook) could easily be the culprit behind a bad battery life on your Android smartphone. Go to Settings and in the Battery section, look at what apps are eating out the most of your battery life. If you find the culprits, either force stop these or uninstall them altogether. Reinstall the essential apps to see if the problem is fixed.

– Turn off radio communications:

We have a habit of keeping everything ON, even when we aren’t using them. From WiFi to Mobile Connection and Bluetooth, communications have a huge impact on your device’s battery life. When you are in no need of Wi-Fi, Bluetooth, NFC, GPS, or even the cellular data, turn these services off. These services slow down the devices by constantly updating and hence draining battery life. Make a habit of only switching them on when you actually need these services and you will experience a huge difference in Galaxy S7 battery life.

– Reduce tethering:

Samsung Galaxy S7 and S7 edge not only allow you to share your mobile connection with others, but they also bring a new feature of WiFi sharing. While this is all pretty cool and helpful when you need them, tethering drains the battery very fast too. Turn tethering on only when it’s needed, don’t keep it on for longer hours, especially when you need your device to last longer.

– Disable location services:

Disabling location services not only helps in increasing your Galaxy S7 or S7 edge’s battery life, but it’s also important for your privacy. We don’t really need the location services unless we are using maps for navigation or any other apps that offer us services or information based on our current location. It’s super easy to enable location services when you are using any such apps, so consider turning it off at all the other times.

– Manage background sync

Some apps consume a lot of battery and when they are left to run in the background, be ready to see your Galaxy S7 run out of a fully charged battery in less than a few hours. Since I don’t use social networking apps, Google Photos works as that one app for me consuming all of battery life in a few hours. An essential and powerful photo storage and sharing app, it doesn’t really need to be run in the background. As I have over a few hundreds of photos that need to be backed up, I enable background sync at the night while plugging my smartphone.

You can do the same with your other apps. Disabling background sync will help you fix Galaxy S7 battery life problems. But, to take advantage of background sync, you can manage it to suit your own needs and at times when you would either be at home with access to a power outlet or won’t need the battery to last you longer.

Go to Settings, Accounts and disable sync for the apps that you don’t need. Power-hungry apps like Facebook, Photos and similar other third-party applications should never be allowed to run in the background at all the times.

– Battery charge cycle:

Not only for Samsung Galaxy S7 and S7 edge, but for all your Android and iPhones, it has long been recommended to let your device go through at least one full charge cycle a month. Full charge means charging the battery to 100% and then completely using it down. Power cycling this way helps in getting accurate battery usage data and is good for your battery maintenance too.

– Use a black wallpaper:

From Settings > Personal > Wallpaper > From Gallery, choose a black Galaxy S7 wallpaper. You won’t find in the default option but you can always find one online or create one for yourself.

– Fix Galaxy S7 battery by disabling notifications:

Receiving notifications for every single app is not only annoying but also eats up resources of both data, battery and the processing speed. Make efficient use of notifications and disable them for apps you don’t require notifications for.

– Restart your Samsung Galaxy S7 and S7 edge:

It is always recommended to restart your gadgets if you are facing any kind of performance, battery, or heating issues before resorting to any other solutions. Hold down that power key and turn the phone off. This simple Android tip might help you solve some battery and heating issues. Here’s how to force restart an unresponsive Galaxy S7 or S7 edge.

– Factory reset Samsung Galaxy S7 or Galaxy S7 edge:

If none of the above tips work for your smartphone, it is time to go for the last resort: factory resetting Galaxy S7. Go to Settings Personal Backup and Reset to factory reset Galaxy S7 duo. Because factory reset wipes off all the data on your gadget, keep a backup before proceeding.

Important: use Galaxy S7 default battery settings

Android 6.0 Marshmallow brought a ton of battery saving features to the devices. Go to Settings, SystemBattery and you will find a Power Saving Mode and an Ultra Power Saving Mode. Using Power Saving Mode, you can make your Galaxy S7 or S7 edge last much longer when you need it. This mode limits the processor performance, turns off vibration, reduces screen brightness, and disables other such features. It doesn’t stop you from using anything, it simply cuts down on fancy things like vibration and screen on-time.

Power saving mode is all awesome, but dire times call for tough decisions. With Ultra power saving mode, you can squeeze hours out of your dying Galaxy S7. In this mode, Galaxy S7’s screen will turn to black and white and a grayscale theme. This means you will go back to the days of phones when they weren’t so smart. You will get limited functionality, including access to text, call and web browsing. But, your phone will last hours, even with a single digit battery percentage.

We hope that the above tips help you in fixing Galaxy S7 battery life issues. You can always choose to enable the airplane mode to disable all the communications with a single tap. Also, don’t forget to make it a habit to occasionally restart your device, as it will fix several battery and performance related problems.
