Why do cell phones have no crosstalk? (and other questions)

I just replaced my old Motorola analog flip phone (#550) with a new digital phone.

I'm disappointed in the sound quality. The analog phone had reasonable sound quality and some crosstalk. The new Motorola digital phone sound is "choppy", as if someone has sliced off bits of the signal. (figuratively and literally). If the other party isn't speaking clearly directly into his phone, it becomes garbled. There is no cross talk at all, and often in the conversation I wondered if we were still connected.

Also, the analog phone had a big LED display that clearly showed signal strength and battery power. The new phone has very tiny little symbols I could barely see.

Is this typical of today's digital phone quality?

Do new digital phones give a warning signal before the battery runs out? My analog did with the older style battery but not with the newer style premium battery.

They say I should "cycle" the battery--charge and discharge. Could someone elaborate?

Thanks!
