The Battery Percentage of Hearing Aids – With the advent of BlueTooth headphones came independence from cables. Here we tell you how to see the percentage of the battery of your BlueTooth headphones in the notification bar of your Android or iOS cell phone.

Not all BlueTooth headsets are well-matched with the function of seeing the battery percentage in the cell phone. In the market for BlueTooth headsets and other BlueTooth devices in general, the role HSP (Headset Profile) and HFP (Hands-free Profile) are the profiles required for typical operations of mono Bluetooth headsets. At the same time, A2DP (Advanced Audio Distribution Profile) and AVRCP (Audio/Video Remote Control Profile) are the required profiles for stereo headphones.

What profiles do Bluetooth headsets use?

HSP (Headset Profile) – Provides the essential functions required for communication between a handset (mobile phone) and a headset.

HFP (Hands-free Profile) – Offered extended functionality over the HSP profile and was initially intended to control a mobile phone from a fixed hands-free unit in the car.

If your hearing aids have a profile of HFP 1.5 or 1.6, it will not show the battery percentage since it is only available from version 1.7.

1. From the notification bar:

Once the hearing aids are already linked to the cell phone, you can see the battery from the notification bar:

2. From the list of Bluetooth devices:

Another way to see the battery is by entering the list of Bluetooth devices on the cell phone, and within all the previously connected devices, you can see the battery of the hearing aids next to the name or below.

3. Why don’t I see the battery on Android?

It often happens in different versions of hearing aids that the battery is not shown in the notification bar or the list of BlueTooth devices.

The battery performance option is not configured in the hearing aid configuration, even though the HFP profile is compatible. So all you have to do is download an app called BatOn. This activates the battery display feature on Android phones.

If it doesn’t work with the app, the hearing aids don’t have a compatible chip. You can download many applications, but they will show you the wrong information. For example, it will often offer a false percentage, so if your hearing aids do not show the battery on the cell phone without the application, they do not support function.

View percentage or battery level on iOS / iPhone

Once linked, you can see the battery inside your iPhone just by sliding from left to right. Once inside the widget bar, you will see the flurry of both the headphones and the battery.

The box’s battery may be available only when you wear your headphones or show the percentage for just a few minutes. So if you don’t see the battery, you have to pair the headphones again.

Why can’t I see the battery on iPhone?

The percentage of the hearing aids is usually displayed at the beginning of the pairing of the hearing aids to the iPhone. Still, in some brands, they tend to disappear after a few minutes, so if you do not see the level or percentage of the battery of the hearing aids, you will have to go back to link them.

How to see the battery level of the hearing aid box?

The box of the hearing aids is charged with the cable included in the package at the time of purchase. You can use a Micro USB cable, a USB-C cable, or if it’s one of Apple’s knockoff headphones. Now you’ll need to use the Lightning cable.

When charging the box, the LED indicator will light up. For example, if the LED indicator flashes 2 times means 50%. Now 3 times means 75%, and 4 times means 100% charged.

The indication may also vary depending on the make and model of the box. For example, when the box button pressed (in case the package has a control), the LED light will illuminate orange with less than 30% battery and a green light when it has more than 30% battery. In other cases, the light is blue or white.

If you have an iOS device, you can see the charge of the hearing aids and the box of the hearing aids within the battery widget of your iPhone when pairing them.

Remember that you should always charge them between 1h30m to 2h maximum unless the manufacturer indicates otherwise.

You can identify the battery in the box in different ways:

  • The light turns blue/green when it reaches 100% battery.
  • The light flashes blue 3 times and then turns solid orange/green when it comes to 100% battery.
  • Furthermore, the light blinks blue about 3 times and then turns off when it reaches 100% battery.
  • The light stays solid blue/orange when it gets 100% battery.
  • The light turns off when it comes to 100% battery.

There are more ways to identify when hearing aids reach 100% battery, but these are the main ones.
