Things we’re sure of
- 4″ Screen (in-cell)
- New Design
Things I’m sure of
- LTE on Qualcomm’s MDM9615+WTR1605L chipset
- 32nm application processor (A6), fast dual core (1.5GHz)
- International LTE (on EU-800 and EU/Asia-1800), but no worldwide LTE roaming (international roaming will be restricted due to 3G due to the different models needed to accommodate the various LTE worldwide bands)
IGZO screen for better battery lifeIt appears that Sharp wont be delivering any IGZO screens until 2013. The good news is they had live demos showing IGZO screens using 60% of the power of a regular screen (1.86W vs 1.1W for a 7″ display). It appears the first IGZO screen will probably end up in the iPad 4 in Spring 2013 (and the battery will go back to 25-30Wh).
- T-Mobile support (if not initially, eventually – definitely by end of Q2 2013)
- China Mobile support (655M customers, again if not initially, eventually, expect before Chinese New Year)
- 5GHz WIfi support (802.11n)
Expected Battery Specs
- 12 Hours talk time (3G, since there is no VoLTE networks running yet)
- 7 hours LTE data
- 9 hours HSPA/CDMA data
- 10 hours Wifi data
- 10 hours video (H.264)
Most of the factors that go into this are that the processors are fabricated on a smaller lithography (28 and 32nm)
and the IGZO screen cuts its power consumption by 50%. This is why the battery is only slightly larger instead of a lot larger than the previous generation.
US GSM: Lower 700 (Band 12), 850 MHz, 900MHz (for international 3G), 2100 (for international 3G), PCS (1900), AWS (1700/2100), WCS (2.3GHz)
US CDMA: Upper 700 (Band 13), 850 MHz, 900MHz (for international 3G), 2100 (for international 3G), PCS (1900), AWS (1700/2100), BRS/EBS (2.6GHz)
EU/Asia (Japan/Korea): 800MHz (digital dividend), 850 MHz, 900MHz, 1800MHz, 2100MHz, PCS (1900), 2.6GHz
- The phone as-is wont support Sprint’s eventual LTE iDEN network. This would require a third US model since it would replace Upper 700 (Band 13) with the iDEN band.
- The radio configurations don’t allow international LTE roaming, just 3G.
- China Mobile may end up using the EU/Asia model, but probably reconfigured slightly such that it can use TD-SCDMA (may or may not require new hardware, probably not but we’ll see).
