Ok, I have been reading some thing about batteries here, and I want to merely state a few facts.
-Trickle charging is not what you people are referring to. If I have a batter made to accept a charge at 10 volts, trickle charging is putting a 2 (or any number less than 10) on it, and getting a smaller current flow. Lithium batteries CAN NOT do this. It ruins the batteries. The ones in your phone will accept a charging voltage at about 5V (USB spec). When you say trickle charge, you mean charge at less than 1 ampere (USB spec is 500mA). There is never any reason for you to charge your battery at anything other than 5V +/- 5% or so. All chargers and USB ports do this. Although in an emergency you can use something else (I have seen a 9V used in emergency b/c current flow is a more important thing no to exceed), it is not advisable nor logical to do that for everyday charging.
-Batteries live longer with a slower charge and moderate discharge rate. Although 1A may be within the appropriate tolerances of your battery (it is what your chargers are set as their max), a 500mA charge if you have the time may be healthier in the long run. Note these are all maximum currents. Depending on the resistance of your charing circuitry and battery, you may be getting less current. The circuit just trips at the max. The voltage is the invariable specification on chargers (except exotic ones that you will probably never use to charge a phone).
-When charging, your battery goes up to out 4.20V per cell. It almost guearenteed has a built in circuit to stop charging at 4.30 V/cell, as that is the border of unsafe. The time you spend at 4.20V/cell should be minimized.
-Lithium ion batteries require no break in or anything of that sort. The first charge is as effective as the 30th, and that is it. That being said, a complete charge and discharge will calibrate the digital charge estimator, and your battery does auto shutoff when the charge is too low (it prevents itself from dropping to "OMG my batter no longer holds a charge after that last discharge" level), so make your own call. Perhaps no more than once a month? I usually do it if I notice the battery indicator is too off, as it getting 3 hours off a charge after it says 10% remaining. I also do it when I first get the battery...I play with it, full charge, full discharge, full charge, possibly another full discharge if it happens (if not, it is probably still calibrated), and that is it.
-Lastly, a point on how a battery charges. It goes up to about 70% charge, and then tops off as the current drops down to about 10% of the initial current. Fast chargers only go up to 70%. The last part, the topping current, takes about 2x the time the first part does.
Hope that clears something up,

I dropped mine in the toilet 
... had it in my back pocket.
