Are you experiencing the annoying low battery warning that some Razer wireless headsets, such as the BlackShark, Barracuda, Kraken, or Kaira, give off, even when the headset is fully charged?
Even if you’ve charged the headset to 100%, you can still receive a fake low battery notification, beeping away, indicating an incorrect charge percentage. This notification sound can interrupt or mute all your other sounds, ruining gaming sessions or Discord conversations.
The intervals at which these notifications come through can vary from headset to headset. You might experience it every 10 minutes or only once; either way, it’s a frustrating experience that some Razer headset owners have experienced.
Note: Some of these fixes are only temporary workarounds and not permanent fixes. There is no way to manually turn off the low battery alert, as it’s hardcoded into the headset.
Here are solutions to try to eliminate this fake battery notification on Razer headsets, even when the headset’s charge is green and full.
1. Time Unplugging The Charge Cable
If you’ve charged the headset to full or a reasonable battery percentage, rather than unplugging it straight away, try turning on the headset for a minute or so before removing the charging cable.
This little trick sometimes allows the Razer headset’s battery level to be updated correctly and show the correct percentage.
Of course, it should show the correct percentage either way, but it does seem to be a little software bug that can occur for some people and is worth a quick try.
Note: You don’t need to recharge the headset again if you pulled the charging cable out before turning on the headset. Simply replug the cable and turn it on again before removing it.
2. Recalibrate The Headset Battery
No wizardry here, and is simply a case of draining the battery and then recharging it fully.
A simple battery recalibration resets the headset’s internal battery tracking and can resolve incorrect or stuck readings that cause false low battery notifications.
It also helps eliminate any rogue charges or charging practices that have occurred with the battery.
Here’s how you can calibrate the internal battery:
- Charge the headset until it reaches a full charge of 100%.
- Completely drain the battery by using the headset until it dies and switches off.
- Charge the headset until it reaches 100% (Ensure it is 100% fully charged).
- Remove the charging cable and turn on the headset (Do not connect it to your computer yet).
- Leave the headset to drain to 0% again, but this time on its own without using it.
- Recharge the headset again to 100% and then connect it to your computer.
If this battery recalibration hasn’t worked, try the process once more to see if the correct percentage will show. It is a little bug that can occur within the headset’s internal battery when used straight out of the box.
3. Re-Sync The Battery Level via Bluetooth
This is probably more aimed at an incorrect battery reading, though this could lead to a low battery notification. It’s worth a try if it keeps getting stuck while charging at a certain percentage.
The trick is to connect your wireless Razer headset to your phone rather than your computer when charging. You want to monitor the battery percentage while charging and connected to your phone via Bluetooth.
Try the following:
- Make sure the headset is turned on.
- Connect it to a smartphone via Bluetooth.
- Start charging your Razer wireless headset as normal when connected to the phone.
- Monitor the battery level until it reaches 100% and is fully charged.
- Disconnect the headset from the phone.
- Connect the headset to your computer and see if it has resynched the battery level to show the correct charge level.
Tip: You can try the Razer Audio app on your smartphone if things haven’t worked or if you’re struggling to connect to it.
4. Switch Profiles in Synapse
It’s a common fix for issues with other Razer peripherals, such as mice and keyboards, but can also resolve headset issues.
In Synapse, simply select your Razer headset, whatever model it may be, and add a new profile. You can always download profiles provided by other people online or by Razer.
Select the new profile and use that as the default profile to see if anything has changed.
One known little trick here is to create a new profile, switch to that, and then switch back to your original main profile that you use.
Just give switching between profiles a try to see if anything works for you.
5. Factory Reset
If you’re getting the wrong battery % showing or false notifications, a simple headset reset is worth trying, just in case the firmware is malfunctioning.
There are a few ways to reset your headset, depending on the model you have.
Soft Button Reset:
The simplest reset is a soft reset, which is performed by holding the power button down firmly for approximately 10 seconds while the headset is turned off.
Wait for some flashing lights to show on the side of the headset, and then you’re good to go. If you have any lights on or they stay static during the reset, ensure the headset is turned off and try pushing the button down again for 10 seconds.
Factory Reset Within Synapse:
- Go into Razer Synapse and locate your headset device
- Click on the help ‘?’ icon
- Select the ‘Reset’ button under Factory Reset
The headset should now be reset. Test the headset to see if you’re still receiving low battery notifications.
6. Relaunch Synapse
Boring fix. We agree, but it might provide you with some temporary relief if you just want a quick break while playing a game.
Simply close and reopen the Synapse software while your headset is connected. If you’re in a game, close it down first before relaunching Synapse.
It’s not much of a long-term fix and will likely revert to giving off the annoying low battery notifications after rebooting the PC.
Note: This fix may indicate an issue with your Synapse installation and is worth checking if an update is needed or if reinstalling the latest Synapse version from the Razer website is necessary.
7. Synapse Updates
The generic, but it should still be checked. In recent times, updates to the Razer Synapse software have fixed battery warning issues for some users and headset models.
Ensure you have the latest version of Synapse installed and check if any updates are available to download.
As a last resort, uninstall Synapse and reinstall the latest version straight from the Razer website just to be sure there are no issues with your current version.
Give The Solutions A Try
Unfortunately, there is no way to manually disable these annoying low battery notifications, even when you have a fully charged headset battery.
Try some of the solutions listed above. Some are temporary fixes, while others can completely eradicate the notifications in certain instances.
As with any of these situations, there’s a slim possibility of a faulty headset straight from the box. If you have tried all the solutions above and nothing has worked, try experimenting with Synapse a few more times to see if anything works.
