For example, the follow-up to last year's HTC One is supposed to boast a 2.3GHz Snapdragon 801 processor, according to a brochure obtained by GSM Arena.
Also, beneath its expected 1080p 5-inch display, the New HTC One has been tipped to be packing a 2,600mAh capacity battery.

Both phones use a Snapdragon 801 system on a chip from Qualcomm, while the HTC One 2's 2,600mAh battery life is close to its rivals.
The Galaxy S5 includes a removable 2,800mAh li-ion battery capacity, while the Xperia Z2 crams in a non-removeable 3,200mAh battery.
It's unknown whether the New HTC is destined to have a removable battery, but that wasn't the case for its predecessor when it launched last year.
The final interesting detail from the brochure indicates that the HTC One for 2014 will include a nano SIM card and slot vs the typical micro SIM configuration.
