On the batteries, at flank you should get about 1/2 hour out of them. That is fairly realistic. Can go all day at 3 knts with the batteries if needed. Pretty close to realistic.

Fuel, not the most realistic but if you watch your speed fuel should not be an issue. I motor to my patrol area at 10 ktns. Once there I conduct the patrol at 7 knts. Flank for the end rounds. Running your fuel in the manner usually allows your 4-5 different assigned areas within your patrol and you should have plenty of fuel to get home. Usually 25% by the time you hit port.

The pop up clock, yep, move it off screen or do what I do as I do use the clock, move it half off the screen. IHMO it should be a bit smaller.

As far as the 4 torps etc. I believe that TM uses NSM, not sure. Personally and with the help of Leo I removed some of the files in NSM to ships sink faster and really, 2-3 torps should take care of the merchant. More often than not, 2-3 torps did the trick. Not 4 torps and 50 shots from the deck gun. The files left behind still provide the reaction of torpedo hits such as the vessel lifting out of the water or rolling over before it sinks. I do not recall what files I moved out. PM Leo, he knows what files these were.
