When your Android battery suddenly drops to zero, it means that your phone’s battery is totally out of health and you need a replacement. So when you are experiencing this problem for more than 2 times, then it is advised to replace the battery with a new original one.

In Battery Principles, we discuss almost all the battery problems that people are facing in their lives. So in this article we focus on the “Battery suddenly drops to zero” problem, and we invite you to stick around until the end to find out what you’ve been looking for.  

Why has my Android battery life suddenly decreased?

Android Battery Sudden Drop to Zero

You will find that every other piece of content on the web says any reason, like abnormal app usage and things like that. But that is not the real scene behind it. What’s behind the battery life suddenly decreasing is battery health.

When a battery is being used for a long time and the charging and discharging cycles quota is exceeded, the battery starts losing its health. As a result of that, the battery starts losing its power storage ability and time. 

When the battery health decreases, the ampere rate and the voltage of the battery also start to fluctuate, resulting in wrong readings in the measuring circuits. 

So that is why you see sudden drops and an increase in your battery percentage. That is very common, and the problem is in your battery. 

What is draining my Android battery down?

When the battery is draining fast, it is different from the sudden fluctuations in the battery level. There are many factors that can cause your Android or iPhone to drain its battery.

  • Abnormal Apps usage. 

There are applications that use a high percentage of the battery when they are running. So when those applications are running you will experience a faster battery draining. 

You can always see how different apps use your battery life in your settings. So when you’ve noticed one or more of them, simply force stop those apps if you are not working on them. 

On the other hand, some mobile phones notify you about apps that use the battery abnormally. That is very useful for you if you save your battery for a long time as expected, it will be very useful for you.

  • Hardware problems.

If it isn’t an old battery or some misbehaving apps in the background, the fault is most likely in the hardware. 

It is possible that the charging board has failed or that something has gone wrong with the motherboard. It’s not an easy fix; you’ll need to send your phone to the manufacturer’s repair shop.

  • Display settings.

When the display brightness is very high and you are using the optimal graphic settings, then the display uses the battery more than when it is normal. 

So, to save power, you must keep the display’s brightness at a minimum level that is OK for the eye, as well as the battery. 

If you’ve turned on the automatic brightness on your display, then it will be easy for you because the phone automatically controls the power usage by increasing and decreasing the display brightness according to the surrounding lights. 

  • An old battery.

This is the problem that we’ve discussed earlier, and it’s the most common one. When the battery’s physical health is low, it cannot be recovered by software means. 

Even if you don’t abuse your phone by charging and overcharging it frequently, Lithium-ion batteries, which are ubiquitous in phones, degrade over time. This could be the reason why your Android battery abruptly dies.

If you are   able to find out what is happening to your battery, then bring it to a phone repair center and they will assist you in fixing the problem as soon as possible.

Why is my phone battery draining even when I’m not using it?

If you want to see which apps are currently draining your phone’s battery, go to the power settings of your smartphone and look at the breakdown of how its power is being used. These apps absorb electricity, which is why your phone’s battery drains even while not in use.

If you use an app for an extended amount of time, it will most likely be at the top of your battery usage list.

However, look for any unusual behavior, especially in programs you haven’t used in a while. Some apps run in the background without your knowledge, draining your Android battery.

Following an update, some apps begin to cause unexpected battery drain. The only solution is to wait for the developer to resolve the problem. If the battery drain is significant enough to be an issue, remove the program until a patch is released.
