According to the manufacturer, the enormous battery in the back of the device provides the impressive 1100 hours of standby – we are talking about roughly 46 days here, folks! As a side comparison, the Apple iPhone 5s gives you around 10 days of standby (250 hours), whereas the battery of a Samsung Galaxy S4 provides around 15 days of standby. Additionally, the Eton Thor is touted as enabling users to talk just shy of 21 hours while they're connected to a 3G network.
Hardware-wise, the Eton Thor is powered by the first true octa-core chipset in the world, the MediaTek MT6592. The smartphone also packs 2GB of RAM and a Mali-450 GPU. Still, the SoC does not support the 4G LTE that China is currently building. There is no information about the display of the device, however.
The price of the Eton Thor is not known, either. However, there is little chance that you'd lay your hands on this 5,000mAh monster, as it would be most probably sold solely in mainland China.
