WhatsApp's dark mode has made several appearances in beta updates in recent times.
And although there is no official word yet, a recent wabetainfo article reports that in the new 2.19.353 update, WhatsApp allows for automatic enabling or disabling of the Dark Theme based on the user's battery saver settings.
This replaces the previous “System default option" for Android versions that were not supported.
The set to battery saver option will now be available on Android 9 and lower versions, while Android 10 users will see the System Default option.
Reportedly, users will now have the option to change their mode to 'set by battery saver', 'dark' and 'light'.
While work continues on the dark mode, WhatsApp is also working on a slew of other updates. This includes, according to reports, a self-destruct message feature, the opportunity to access your WhatsApp account over multiple devices simultaneously, and more.
