I ran into an issue with Razer Synapse 4 not showing wireless battery percentage for 2 different wireless models.
Both are listed as officially supported and backwards compatible with Synapse 3 and both had the same exact issue with no battery percentage displaying. I uninstalled Synapse 4 and reinstalled Synapse 3. BAM! I can now see all wireless mouse battery percentages. I attempted to troubleshoot with support but it took way too long to get valuable responses and I’m not interested in downloading a software log capture tool. Will check out Synapse 4 at a later date perhaps.
I thought I’d post this for anyone who has a similar problem as all of the threads I’ve seen are requesting PM’s and don’t show a resolution status or troubleshooting steps.
