Intel showed the first Broadwell-based laptop prototype in September last year. The company is expecting Broadwell to be 30 percent more power efficient and faster than Haswell counterparts. That translates to longer battery life than Haswell laptops. Lenovo has claimed its ThinkPad X240 with Haswell chips could offer 17 hours of battery through internal and swappable batteries.
Intel has had its share of troubles with Broadwell. The chip maker delayed production of the processors due to manufacturing defects, which analysts said could postpone the launch of PCs based on the new chip architecture. Intel went on to say PCs based on Broadwell could be expected in the second half of this year, though no exact time frame was provided.
