Why does the Spring and Verizon phone only have up 8 hours of talk time?
Why does the Spring and Verizon phone only have up 8 hours of talk time while the Unlocked version has up to 23 Hours of talk time? If i get the unlocked version then connect it to sprint will it still have up to 23 hours of talk time?
In short, the unlocked phones are GSM/UMTS based. So, they will not work on Sprint or Verizon's CDMA (IS-95) networks. CDMA networks (Sprint and Verizon) cause a greater battery drain on a mobile. In CDMA, it would operate best if cell coverage areas can overlap one another. But that is impossible because of buildings, highways, or just zoning that will not allow this to happen. This triggers the rake receiver (multiple fingers locking on to multiple cells..normally 3 will lock while one is searching for next best signal) in the phone to work harder to maintain proper RSSI (signal strength). Performance is slightly better on W-CDMA (used by at&t and T Mobile) because of the guidelines set forth by 3GPP.org. Talk time is slightly better depending on distance of tower (cells) but some features are based off of GSM standards and maintaining battery life of the mobile is a priority. Hopefully this helped without getting into the full theory of CDMA vs W-CDMA
