I recently purchased the Monaco 3500 battery for the Samsung Epic, this past March, because I was frustrated with the batteries I have with this phone. This phone can go through some batteries, maybe I had a ton of apps, or I was not optimizing the battery, but I have about 3 extra batteries, 1 or 2 are 1300 and one 1200.
The Monaco 3500 worked great, I could go a whole day with minimum interaction with my phone and it would last the entire day, instead of the half a day with the stock battery. The door is bulky, but whatever, that is the least of my problems.
Now, I will mention, I have completely replaced my phone, minimized the apps that I absolutely use, and it has worked great. But, in the last couple of days, I am not sure, if its the battery or the charger, because some days, I can get to 15-20%, then next thing you know, its completely dead. I have seen it at 52%, next thing I know, the phone is off, turn it back on, battery completely drained.
The only reason I came on this forum today, was because last night, I was trying to charge it, and while doing things on the phone, with the phone plugged up to the charger, the battery continued to go down. Once it reached zero, and I unplugged it from the charger, the phone of course shutdown. I removed the battery and placed it on another type of charger, and its been charging for several hours.
So, to date, the jury is still out on this battery, because, I can easily go back to other batteries, but of course, now I have to carry the custom cover also. Anyone else having issues with this 3500 battery?
