The latest Lenovo smartphone, S860 is well known for it's strong battery life. The good news is, the rumor said that they are working on a new smartphone that provides more battery life, the Lenovo P70t.
This 5 inch 720p Android smartphone uses MediaTek MT6732 64-bit quad-core 1.5GHz ARM Cortex-A53 with LTE support. It has 1GB of RAM, 8GB of internal storage, microSD slot, dual GSM slot, 13MP rear and 5MP fron camera. Lenovo claimed that this model will come for cheap. No pricing information though.
Sigh.. if only it has 2GB of RAM.
