"Conditioning" the battery by juicing it down to 0% and then charging back up to 100% seems to be the conventional wisdom on this forum. Some even recommend doing this for the first 3 days of battery life.
However, from a technical stand point, there is no need to do this. The old nickel-cadmium batteries did indeed have a "memory". With these types of batteries, it was better for long time performance for you to do the "conditioning", as described above.
Lithium-Ion batteries, however, DO NOT share this characteristic. You SHOULD -at least technically speaking- not have to "condition" your phone with the above technique.
Now, having said that, I still find myself "conditioning" the battery for the first few days. I've researched enough about battery technology, that I know better, but I'm a creature of habit, I guess. Do some research outside of this forum into lithium-ion batteries, and make your own decision.
Now, I keep putting "conditioning" in "", because that is not really how I meant it in my original post. What I meant by conditioning, was just basically using the phone (phone/3G/wifi/GPS/etc.) repeatedly over a period of time. As I said, my stock battery seemed to improve much over the first few weeks of use. I can only assume that the 1750 will increase in time as well.
However, I have heard that digital battery life displays (like the battery widget I have from the market) can have some sort of "memory" effect. If your not routinely showing the software what your battery max's and min's are, it can configure its 0% and 100% to what you show them to be, and thus, become inaccurate over time. Juicing your phone to dead and charging to 100%, maybe once a month, should result in keeping those apps more accurate. I don't personally know if this is true, but I've heard it enough to think it's worth mentioning.
Hope this helps.
