I had a couple of interesting experiences with charging and battery usage. One night, I was playing around with various apps right after charging. Everything was fine; battery went down to 90%. I turned off wifi and put it back in the dock.
The next morning, the battery was at 50%. Hmm. Shut down the phone, put it back in the charger (which turned it on, of course). An hour later it was at 100%. Went to work. The next time I looked at my phone, two hours after charging it, it was down to 30%. WTF? No apps running. Dead by noon.
Went home, charged again, and it was fine. No explanation.
Last night, I had it connected to my computer to transfer files. Battery went from 80% to 20% in three hours and the battery was overheating at 129 degrees. I went to the battery usage screen and got this:
com.android.email - 40%
Android System - 29%
Display - 13%
Phone Idle - 8%
Cell Standby - 6%
Media - 5%
This isn't the first time I've seen com.android.email sit at the highest battery usage. In fact, it usually is even though I have Exchange set to sync every 15 minutes. (I can't control GMail.)

com.android.email - 79%.... When I shut this down, what does it prevent? checking all of my email accounts?
I have had my new Droid since Saturday 11/28. I have been reading everything I can and setting my options to the best possible while still being useful for saving the battery. I unplugged @ 6:32 am today and have my Bluetooth running, have made 36m worth of voice calls. Had my email being checked every 15m on a single account. Received 3 text messages and sent 2. No web browsing and no game playing. Goggle Talk, Android Keyboard, Corp. Calendar (which I have killed) and bluetooth updating service is all that is running per the app manager in the settings tab. GPS and WiFi are turned off. Screen brightness is at just under 25%. My battery is now @ 40%. Battery usage states that 56% of what has killed my battery so far is the paltry 36m worth of voice calls (this was only 2 different calls by the way). Correct me if I am wrong, but shouldn't I be getting better results then this? Someone did mention that they were able to get a new battery under warranty...is this something I should consider? Thanks for any help ahead of time
Most of the time it's stated to prolong the life of these types of batteries you should run them down all the way and then charge them, above it's stated to charge them as much as possible, is this true? then i'm happy cuz I charge my Droid as often as possible.. thanks
And the Wikipedia article on Li-ion batteries stating that there is no 'memory effect':Memory effect, also known as lazy battery effect or battery memory, is an effect observed in nickel cadmium rechargeable batteries that causes them to hold less charge. It describes one very specific situation in which certain NiCd batteries gradually lose their maximum energy capacity if they are repeatedly recharged after being only partially discharged. The battery appears to "remember" the smaller capacity. [1] The source of the effect are changes of the characteristics of the underused active materials of the cell.[citation needed] The term is commonly misapplied to almost any case in which a battery appears to hold less charge than was expected. These cases are more likely due to battery age and use, leading to irreversible changes in the cells due to internal short-circuits, loss of electrolyte, or reversal of cells.
Lithium-ion batteries do not suffer from the memory effect. They also have a self-discharge rate of approximately 5-10% per month, compared with over 30% per month in common nickel metal hydride batteries, approx. 1.25% per month for Low Self-Discharge NiMH batteries and 10% per month in nickel-cadmium batteries.[31] According to one manufacturer, Li-ion cells (and, accordingly, "dumb" Li-ion batteries) do not have any self-discharge in the usual meaning of this word.[21] What looks like a self-discharge in these batteries is a permanent loss of capacity (see below). On the other hand, "smart" Li-ion batteries do self-discharge, mainly due to the small constant drain of the built-in voltage monitoring circuit.
For your information, we currently offers an Innocell 2600mAh Extended Life Battery that will give you nearly double the battery life! Here are some photos:

Not sure how you got 50% after 14 hours, but hell i want that battery, can you ups that to me pls
Dear God...that is ugly. I love you Seidio, but that is fugly.
I'm hoping their slim battery (that is in development) that uses the stock battery cover has a decent increase in capacity... that one may be worth the wait.
