It's clear you don't actually own a SDS100, and are merely regurgitating secondhand misinformation and urban legends without attempting to apply logic and common sense.
The first batch of SDS100 scanners shipped with a battery that only lasted about 5 hours. But Uniden was clear about what the battery life would be for the early adopters, and promised a free larger battery with an 8-hour runtime, once they became available, to everyone who purchased one of the initial batch, BEFORE the first SDS100 shipped. And Uniden delivered on that promise.
Some people complain that the SDS100 audio is too tinny. It's not possible to fit a speaker with good low-frequency response into a SDS100 case. If you want more bottom end from the speaker, you need to make both the speaker and its enclosure larger. There's plenty of bass if you listen on headphones or an external speaker, though. Other people say the SDS100 audio is fine, and the SDS200 has too much bass. You can't please everyone.
And the fact remains that without good analog receiver performance, you can't have good digital receiver performance. You can't decode meaningful bits from static; the receiver has to send a reasonably clean RF waveform to the ADC before the digital side can do its mathemagical stuff. It's mathematically impossible (literally) for a digital radio receiver to have digital performance better than its analog performance, because all signals start out analog when they come in from the antenna.
