Really Android Tuner 0.7.2??? If so, that is pretty old. I'm using the latest AT free (0.12.7.1) and it shows 2100mA. The incorrect value may or may not represent a problem. There's an option in there to update the capacity (but only in the non-free version so I don't really know what it does). You might also want to look for some alternate system info app that reports the battery capacity and see what it says.
Battery monitoring tools have exploded in the past few months but Better Battery Stats is still the gold standard. Whatever you choose, you will probably find out that a lot of the stock apps keep your phone awake a lot and it's best to freeze whatever you can. Also, default settings such as sync frequency, location access and so on will also lean to the side of usefulness rather than battery life. With some tweaking you should be able to get it to a level you can live with.
The best I've been able to get is about 1.5% drain per hour when idle, about 36 hrs total between charges with light use, but that was with nearly everything useful disabled. Out of the box I was seeing 5-6%/hr when idle - ow!
