Remove AVG. Its terrible on the desktop and useless on a tablet.
But installation of a task manager can be useful - there are a few reasonable & free ones available in the Play Store.
How long are you actually finding the battery lasting?
Can you recommend a good anti virus if I need it please?
If I go on it a couple of hours, which I don't do normally, it's just I am trying to get used to it. It will go down about 25%.
It's the idle bit using 50% battery that doesn't seem right, as I don't leave idle or sleep mode. I shut down propely.
I was on my laptop. Now back on My Hudl is now 93% battery and 35% idle and WiFi 34%
