The battery drains too quickly. And there is a fingerprint recognition error.

Hello, I received delivery of my device yesterday.
I am using it with overall satisfaction.
However, the device gets extremely hot during communication and the battery drains quickly.

Another issue is that when using the Chrome browser, touching the fingerprint reader causes the page to refresh.
Because the fingerprint reader is located within easy reach of your fingers, it is very inconvenient for this to happen.

Can I solve these problems?

I solved the problem of Chrome browser refreshing when using the fingerprint scanner by remapping it through the 'Button Mapper' app.

I put a flip case on mine, and that practically eliminates the issue, as you are then unlikely to accidentally trigger it.
We have a terrible long thread on (mainly DIY) cases, but long-story-short, it requires either a 3D-printed case or some tinkering with existing cases.
I have my own blah blah on the cases I made, and have been using for five years here.
