Facebook has launched an investigation over complaints of 'excessive battery drain' caused by its mobile iOS app.
In a statement provided to TechCrunch, the social networking giant said it was examining reports the app continually runs background processes even when it is disabled - significantly running down the battery life.
A spokesperson said: "We have heard reports of some people experiencing battery issues with our iOS app.
"We’re looking into this and hope to have a fix in place soon.
Circa co-founder Matt Gilligan said Facebook's app had been responsible for 15 per cent of all battery drain over a seven-day period despite when background processes were disabled, in a blog posted earlier this week.
He wrote: "“Because the app isn’t ‘sleeping’ properly when I hit the home button, it continues to drain.
“That extraneous background usage, despite not providing any value to me at all, is keeping the app alive two times longer than my actual usage.”
