This is pobably one of the worst types of shots to use to make any judgement about whether your camera is working correctly. Trees can be a problem for any camera and there is little contrast in the scene. To check the focus, take some shots of a more two dimensional scene with distinct edges - like text on a large sign. Many people take photos of a brick wall with distinct joints. I use a large world map hanging on my wall. Also use a tripod to eliminate camera shake from the variables. And chose a very distinct, contrasty vertical or horizontal line to focus on. And take a bunch of shots. With this arrangement you can and should use a wide aperature to check the auto focus at the shallowest depth of field.

Good luck.

If it's the firmware about battery level accuracy, I've done it, If it's a new "hidden" one, what does it do ?

It seems that the original 1.01 firmware was silently updated (from to since the time it was officially released. No one knows for sure what it does.
