Recently I've noticed that, opposed to the previous 400-500mb, my tablet is using around 680-750mb of RAM. I have not downloaded anything new recently, and the apps on the running thing (and cached processes) on the settings use probably about 60-70mb in total. My battery % thing has also become very inaccurate, although this could be completely unrelated. I have Avast and have not visited any dodgy websites or downloaded any dodgy apps, so it can't be a virus. Does anyone know why its using so much more RAM? Thanks.
