Help Battery dies FAST!!!

[landovr]

So my wifes phone is only two months old and the battery is acting really wierd. Yesterday she sent two text messages and after 11 hours the battery was at 12%. This morning the battery was fully charged and I took the battery out and put it back in and turned it on and the battery is at 79%!!!!!!!!!!!!

Update: After putting the battery back in and reading 79% I charged the battery to 100% and took the battery out and put back in and still reading 100% so I guess for some reason it was getting an incorrect reading of the battery charge. We'll see how it does after a day of use I guess.
