Tablet generally declining

Hi, I've had my tablet for about four years and have loved it. Recently, as in the last few weeks, I've noticed a decline in its ability to hold its charge compared to before. I know that it's rather old and It won't run as before, but there's a difference from having charge every three to four days to every single night, when I'm doing even less on it than I was before! Now my camera says it's stopped working, but it did a few weeks ago. I've got it in airplane mode most of the time and still it dies quickly. I don't want to factory reset as I don't think that will help either the camera or battery situation. There hasn't been a software update in over two years, which I've checked online using my Imei number. I know Sony no longer manufacturers tablets. But surely there should still be some sort of software care? As I think that might help!! Device info as follows: 

Imei /idid: <personal information removed>


Android 6.0.1


Security patch level 1 May 2016


Help please!

This is an old post, but yeah, lithium batteries will not retain charge as when new, any brand.
