I've been told that modern phone batteries are best to keep topped-up and that the battery life is actually more affected by the number of (near) total discharges. So keeping your phone connected to a charger/USB/Cradle shouldn't have any negative effect on battery life whatsoever..... correct me if I'm wrong....

You should get about 500 charge cycles out of a lithium battery (where charging from 50% to 100% would be 1/2 a charge cycle). So it doesn't matter how often you charge it or how full/empty the battery is when you do it. Apparently the only reason to fully discharge this type of battery is to keep the battery status indicator accurate, so a full discharge/recharge ever month or two should keep that sorted.
Well that was right a year or so ago, unless anyone else knows better.

"Memory Effect" is a condition of reduced battery performance (and eventual failure) due to a battery only using those cells that are fully discharged and charged on a regular basis. In other words, if on a regular basis a NiCd or NiMH battery is only partially discharged before being recharged, it " forgets" that it has usable capacity to further discharge all the way down. The result is degraded battery performance and shorter battery life because the battery is using less than it's true full capacity. Lithium-ion batteries do not develop the "memory effect". NiMH batteries, while considerably better than their NiCd counterparts, are prone to developing "memory effect." However, proper care and conditioning over the life of a NiMH battery will significantly reduce the potential negative impacts"
