Why does a battery warning keep popping up on my phone?

[AC Question]

My phone keeps randomly redirecting me to the Internet and saying 'mobile phone battery module is not upgraded, easy to cause battery to leak and the system shuts down, files and data loss eventually' then there's a link below to download the upgrade which I haven't pressed because I'm worried it may be a virus. Does anyone know why this is happening? If so please let me know, thanks.

It sounds bad. Report it to Google.
