Samsung do need to optimise the battery and software alot better hoping they do via an update as 4100 battery should really last 1 and half days maybe 2 but it's when the device isn't being used that it seems to drain alot
Just letting peeps know that in order to avoid any confusion I've edited Anerola's post above to include the post they were responding to.
Thanks!! haha I was so confused when I went to look!
For me nothing has worked yet... right now I'm on 56% and I have only used 1hr.59min of active screen use. Can you imagine, 50% of battery for 2 hours of real use...... crazy...
