I currently have two batteries. I have a standard battery and an extended battery ( which I use on a regular basis ).
My question is if I charge the extended battery, put it into my desk or whatever, and use my stock battery...will the charged extended battery keep it's chrge until I need it?

I like the extended battery, as it has a 2-3 day battery life, but is quite weighty. The stock battery is a day, tops. I could deal with that while at work or home, but when travelling I would need the extended battery.

Sooo..if I charged the extended then put it away, will it keep its charge for a while?
Also, would it freak out the phone changing batteries with different charges?

 

Thanx for the reply!

By freaking out, I mean this:
As I have been charging the same battery for a bit of time, I noticed that the phone somehow has been 'smart' about it.
When I first installed the extended battery, it took a long time to charge it, but it's discharge rate was quite high. As I charged it over and over again, for smaller times, it seems to be lasting longer. At first, I had to charge it overnight. It lasted a day. I then recharged at work, which took about 4 hours. Lasted two days. I have charged it here and there through the computer and the car and it took less to get to 100% and lasts longer now. I have not changed my browsing/phone/data habits during this. Just seems strange, but I am uneducated about the battery.

 

Thats not too bad! I can deal with that. And considering that this phone has a regular USB connection, I am fine with that. I have a USB connection in my vehicle
