Here's what I mean about managing your expectations, explained in very simplified terms. The original battery is rated at 1300mAh, and gets you about 3 to 3.5 hours of heavy use.. Surfing, IM'ing, etc - all constant use. We'll split the diff and say 3 1/4 hours. So take the 1300 and divide by 3.25, you get 400. So the phone requires about 400 per hour of usage. The new battery is rated 1750mAh.. Divide that out to get hours, and it works like this: 1750/400= about 4.37. Essentially, you get about one more hour of active usage from this battery. Simplified, but that's about how it works. So if you found a magic battery that did 2500mAh, you could figure out how long it would last (2500/400= about 6.25 hours constant usage).
In a nutshell, smartphones like those in the Droid family need more power than other phones. Definitely expect to charge it at least daily. This battery should help get through the day, but it can't perform miracles or break the laws of physics. ;)
So, yes, it worked and held a bigger charge, at first. But now, it's garbage. I'm going to buy one of the cheap batteries you see here just to hold me over until I get the new iphone 5 later this year (or NEXT year, the way things are going!).
However, on AVERAGE use, on the first charge, this battery has blown the stock one out of the water. It runs way cooler, and the rate of decay (according to system panel widget monitoring) is roughly half that of the stock battery. Wow. Average use puts me at 78% 8.5 hours after unplug, where the stock battery would be at 50% or less according to the measurement history. Also, it is simply running cooler. Just wow. It is criminal they don't include this battery with the phone.
For example, I've had it for a couple weeks, and I'm positive it's had the 8 hr charges everyone is mentioning. However, last night, the battery was in the YELLOW by 4pm...I was in church a good bit of the day, so there was no heavy usage. So when I came home and put it on the charger...it was hot by the way..it charged, but remained hot. I went out Sunday night and the phone didn't make it. I don't know. It seems like when it gets warm, the battery drains...even on the charger.
Anyway, I thought this battery took some time to condition. Now that I am rooted (thanks XDA Developers!) and have been reading up on it, I believe it is the PHONE that needed to be conditioned. The battery itself isn't going to change in its capabilities, but the phone can learn how to charge it better.
I recommend "bump" charging. After the phone reports 100% charge, turn it off and unplug it. Then plug it back in - still turned off. The LED will show orange for a significant amount of time after this - and the battery will take more charge. This battery often takes 30-45 min of "extra" charge in my phone while turned off. You can repeat this process (unplug it and re-plug it) without turning the phone back on (it doesn't work with the phone on). Using this technique, I got the phone to stay above 90% for the first couple hours of usage with light usage. I believe you can get a good 20% more out of it by bump charging. The first bump is most significant - subsequent bumps will usually turn the LED back to green in less than 20 minutes. I have generally stuck with 2 bumps. When I do, I notice a significant difference in the life of the battery. Hope that tip helps others.
Today, I am ordering a stand/second battery charger so I can always have a charged battery on hand. Also, my understanding is that the chargers simply charge to full and do not have the same software logic about when a battery is expected to be full, so hopefully this will work for me to keep both batteries fully charged and easily swappable.
I also plan to try to re-train the phone. It was originally trained on the 1300, so I think the significant bump-charging is due to the phone thinking it should stop charging the battery too soon. When rooted, you can reset the battery memory file and re-train the phone. Going to give that a shot and see if it helps.
