Help I uninstalled the Facebook App and it somehow keeps draining battery

[wilvur7]

So... FB app was taking a lot of battery, so I decided to uninstall it. One day later I find in my battery use feed that the app "com.facebook.katana" keeps draining battery. I've checked everywhere, but the app is no longer there, it just appears in my battery feed.
Is it a virus? Is there anything I can do?
Thanks!

The battery use app is reporting everything that was used since it started counting, even though that app is no longer on the phone.

FB's app is extremely hoggish about battery power.
much better to just use a browser, if you want to conserve battery.

You can Reset the Battery Use chart by allowing the Battery to be 100% charged.
that resets the power use to zero again.


On a side note:
you can limit how FB uses battery power, by turning off Notifications,
and making it a point to always turn OFF both Data and WiFi when you are not using the phone.

That is what I do, this is the items I have just looked at... there are more, I just didn't show them.

FB use is 2%
idle 2%
screen 9%
Cell standby 13%
Android 53%

that is over a 17 hour period.

note, I said that the Internet is OFF when the screen is locked.
