Question. What does it trickle charge down to? 90%? Or does it just keep discharging?
I mean, its not a big deal to me as i have full Sprint bars and leaving my Pre now over night i lost about 5%.
That's not what "trickle charging" means. Most rechargeable devices have a circuit that, when the battery is full, will continue to "trickle" energy into it to keep it at that topped-off level until it's unplugged. The Evo, on the other hand, charges to max (or is it only to 90%?) and then stops charging altogether. It's basically not drawing any current from the charger once it goes green, so if you plugged it in at 10pm and left it all night, it might charge by midnight, but then it would be running off battery power until morning, so it's basically taking 6 hours of standby time off your day before you even get up. More if you leave your radios on all the time.
I can't imagine it would be hard to change this at the software level, or even hack it. If I was a programmer I'd write an app for this right now.
