Why Suddenly Samsung Phone Battery Draining Too Quickly?

Sudden Battery Drain Syndrome is a dreaded problem of Android smartphones. A major sign of Sudden Battery Drain Syndrome is quick battery drain without any heavy usage. It can be so bad that after a full charge, the smartphone is completely drained within 2 hours without using it.

I must inform you that the price of Samsung’s battery is not just huge. In India, it costs around $12 in the service centres. But, you should troubleshoot the thing, find the culprit, and take a full backup.

As it happens suddenly, the first and foremost important work is to recall what app you have installed within the last 7 days. An uninstallation unlikely to solve the problem, but still it is a practical first step. The second step is to reboot in safe mode, charge it to 90% – 95% and watch for the rate of discharge. If the problem persists then it is the infamous “Sudden Battery Drain Syndrome”. There are limited things you can do before visiting a service centre:

1. Google services are the usual culprit behind creating the condition. Open Google Play and update all the apps. Check for any software updates.
2. Click on Settings > Go to Battery and Device care > Tap Battery > Tap on the Graph to view the apps sucking battery. Therein, you’ll be able to know how the battery is consumed ranging from Apps/systems to hardware devices.

Different Google services sometimes get stuck resulting in a power drain. The constantly polling process results in a rapid drain on the battery. Often this happens in a particular model of the phone running a certain version of Android. It is not unusual to end up with a near-dead Android phone. Remember – poor network coverage can drain the battery quickly. Sudden Battery Drain Syndrome requires testing activating airplane mode.
