If you own a portable speaker and you’ve noticed they get quieter over time as they play music, you are not alone. One question many people ask is, “are speakers louder when they are fully charged?” After researching this subject, here’s everything I learned.  

In short, yes. Battery-powered speakers are usually louder when fully charged than when they are on low battery. This is because the speaker drivers are able to draw more power required to produce a louder sound from a fully charged battery.

If you are looking for a short, straightforward answer, there you have it. However, if you want to learn more, I recommend you keep reading. I’ll also share some tips on other ways to make your speakers sound louder. 

And then, I’ll follow that up with how the battery life of your portable speaker affects the sound quality. Let’s get straight into it.

Why Speakers Are Louder When Fully Charged?

The part of a speaker that is responsible for the sound we hear is the driver membrane. This membrane moves in order to produce the sound we hear. I explained, in detail, how speakers work in this article. Feel free to check it out.

Speaker’s driver requires power before it can move to output the sound signals that get to them. And as you already know, for battery-powered speakers, the speaker driver gets its power from rechargeable batteries. 

When the speaker batteries are fully charged, there is more power available to drive the speakers. And this is why you must have your speaker’s battery charged when you intend to play them loud.

Fully charged batteries can supply such large amounts of power needed by the speaker drivers to play loud music. Due to this, fully charged speakers will sound louder for longer durations than speakers with low battery percentages. 

As the battery of your portable speaker gets lower, you would realize that the volume of the music being played reduces a little.

What Else Can Make a Speaker Louder?

Apart from ensuring that your portable speakers are fully charged, is there a way of making your portable speaker sound louder when its volume is at the maximum? 

The truth is, a portable speaker cannot be made to sound louder than the maximum volume level it has been designed to play at. 

The best that can be done is to direct and channel the sound energy it creates in a way that makes it seem louder. And there are a few hacks you can adopt to make your portable speaker sound louder.

These hacks deal with the positioning of the speaker and the setting it is played at.

A simple way of getting your portable speaker to sound louder when its volume is at maximum is by putting it on the floor. This is so easy to do and does not need any technical expertise to do so. 

The reason behind this is that when the speaker is on the floor, the bass sound that comes through the speaker has more expression and sounds more precise. This ultimately amplifies the sound from your speaker.

Apart from this, using your portable speaker in a confined location can also make your speaker sound louder. This is because, in a confined location, your speaker’s sound waves get trapped and bounce off the walls. When this happens, all the sound waves fill up the room, making it sound louder.

Another way of amplifying the sound produced by your Bluetooth speaker is by placing it closer to or against a wall. Doing this can increase the volume of your speaker by about 25 percent or more. 

This can be attributed to the fact that, when a speaker is positioned this way, the wall serves as a reflector of waves and as an amplifier as well.

These are hacks or ways to get your portable speakers to sound louder than their maximum volume threshold.

Does Playing Music Louder Use More Battery?

Yes, playing music louder uses more battery life from your portable speaker, thereby causing it to drain faster. This is because more electric current is needed to drive speakers to play louder. The louder you want your portable speakers to play, the more power it draws from the battery.

As you may already know, the power that portable speakers depend on in order to function is obtained from the battery. Thus, playing music louder on your portable speaker causes more power to be drawn from the battery, ultimately causing it to deplete faster. Therefore, playing music louder uses more battery power.

Does Battery Level Affect Sound Quality?

As you may already be aware, the sound quality produced by a portable speaker primarily depends on its build quality. Some manufacturers are known to make portable speakers that sound really good and have excellent sound quality. 

Unfortunately, what you may not know is that the battery level of your portable speaker can affect its sound quality as well.

In general, high battery levels in portable speakers are directly proportional to high-quality sound. This means that whenever a portable speaker’s battery level is at a higher percentile, it outputs great sound. 

On the other hand, the quality of sound that is output by portable speakers tends to reduce as their battery falls.

For most portable speakers, the sound they produce tends to distort and sound weird whenever their batteries go low. The bass they produce at low battery levels may also be uncharacteristically low. 

Thus, you may notice that your speaker does not have full sound clarity and enough loudness. Therefore, the battery level of your portable speaker also affects the quality of your listening experience.

Does Speaker Volume Affect Battery Life?

Yes, speaker volume affects the life of the battery. This is because the volume of a speaker is equivalent to how loud the speaker is playing. Since playing music louder uses more battery, it means speaker volume affects the battery’s life.

There are lots of electronic components inside Bluetooth speakers that consume power. Some of these power-consuming components include; an audio preamplifier, a digital-analog converter, a processor, and a Bluetooth transceiver. 

However, among all these components, the audio preamplifier consumes the most power in a speaker.

This audio preamplifier is the component responsible for volume adjustment. It is also responsible for providing power to the speaker drivers. More volume requires more electrical power. Thus, whenever volume increases, more power is drawn from the batteries by the preamplifier and provided to the speaker drivers.

Since a portable speaker runs or functions on the power that comes from its battery, any power that is consumed by the components of the speaker is drawn from the battery. 

Therefore, speakers consume more power whenever the speaker is playing louder, ultimately causing the battery to deplete.

With this in mind, if you want to extend the battery life of your portable speaker while it is playing, you need to play the audio or music at a lower volume. Doing this will enable you to listen to your portable speaker for longer durations.


In summary, battery-powered portable speakers usually sound louder when fully charged than when they run low. 

This can be attributed to the fact that; speakers use a large amount of power to play music or audio at higher volumes. Thus, when these battery-powered portable speakers are fully charged, there is enough power available to drive them louder.
