Bezels of oblivion
I have not used old HTC phones but used M8/M9, HTC 10, and U11 and U11 is best in my opinion..previous htc phones was average in battery life and camera though sound/software was still great....it personally come down to our preference that we we do like most in phones i.e camarea, design, sound, battery life, price to spec ratio, software etc
I had the M8 and it was a fantastic phone. I swapped it for a M10 and I am well disappointed. It's slow and the battery on it is crap. My works note 8 is brill. I am reluctant to touch another HTC.
The Desire HD was a great phone weighing in at 4.3 inches and 800 resolution. One Plus seem to have taken the baton from HTC in terms of value for money.
Excellent battery life . Its capacity only 3000mAh but getting same screen on time what i used to get from p20 pro and others phones with much bigger battery
