Can you charge it, let it run down and then post your battery statistics. Right now, we're all shooting in the dark a bit. Better understanding your situation with verifiable stats might help pinpoint the issue.
You need to restore it if it gets "super hot" while charging and won't charge higher than 89%.
If it's not doing these things anymore, don't worry about it. A 39% drop in the battery in 1.75 hours is fine with battery-intense types of usage. I get about 5 hours out of a full charge when using the internet.
