Edit: I should note this was on the 6/24 build. May not be an issue on newer builds.
I've actually noticed a problem when on LTE/CDMA. Signal strength seems to drop considerably for me. On LTE/CDMA/EvDo/GSM/WCDMA I will have 4 bars at home. Switching to LTE/CDMA drops it to 2 bars. Can't explain it but I tested it multiple locations and every time it drops by around half.

Just tried that... it didn't drop off for me. But then again, I could be in a particularly strong signal area.
