Checking the remaining battery charge
You can check the remaining battery charge of the rechargeable battery.
When you are wearing the headset
When you remove the headset from the charging case and put on the headset, voice guidance indicating the remaining battery charge of the headset can be heard from the left and right units of the headset respectively.
“Battery about XX %” (The “XX” value indicates the approximate remaining charge.)
“Battery fully charged”
The remaining battery charge indicated by the voice guidance may differ from the actual remaining charge in some cases. Please use it as a rough estimate.
When the remaining charge becomes low
If you hear the voice guidance say, “Low battery, please recharge headset”, charge the headset as soon as possible.
When the battery becomes completely empty, the headset sounds a warning beep, the voice guidance says, “Please recharge headset. Power off”, and the headset automatically turns off.
When you are using an iPhone or iPod touch
When the headset is connected to an iPhone or iPod touch over an HFP Bluetooth connection, it will show an icon that indicates the remaining battery charge of the headset on the screen.
A: Remaining battery charge of the headset
B: 100% - 70%
C: 70% - 50%
D: 50% - 20%
E: 20% or lower (needs to charge)
The remaining battery charge of the headset is also displayed on the widget of an iPhone or iPod touch running iOS 9 or later. For more details, refer to the operating instructions supplied with the iPhone or iPod touch.
The remaining charge which is displayed may differ from the actual remaining charge in some cases. Please use it as a rough estimate.
When you are using an Android smartphone (OS 8.1 or later)
When the headset is connected to an Android smartphone over an HFP Bluetooth connection, select [Settings] - [Device connection] - [Bluetooth] to display the remaining battery charge of the headset. It is displayed as “100%”, “70%”, “50%”, or “20%”. For more details, refer to the operating instructions supplied with the smartphone.
The remaining charge which is displayed may differ from the actual remaining charge in some cases. Please use it as a rough estimate.
Hint
- You can also check the remaining battery charge with the “Sony | Headphones Connect” app. Android smartphones and the iPhone/iPod touch both support this app.
Note
- The remaining battery charge may not be properly displayed immediately after a software update or if the headset has not been used for a long time. In this case, repeatedly charge and discharge the battery multiple times to properly display the remaining battery charge.
