HTC One vs Samsung Galaxy S III44
HTC doesn't list official talk times from the 2300 mAh unit in the One, while Galaxy S III pegs its 2100 mAh battery as capable of a more than 11 hours convo in 3G mode. The S III also scores pretty high in video playback hours, pegged at around ten, while unofficial tests show the One to master about eight, but in browsing endurance the HTC One will likely beat the S III handsomely on account of AMOLED's higher power consumption while displaying white backgrounds, so it would be a pretty tight overall score in the end.
Samsung's Android mojo does a disservice to the Galaxy S III with its ability to lose value slower than other brands. Granted, without carrier subsidies the Galaxy S III is roughly 20-30% cheaper than the SIM-free HTC One, but you get so much more from HTC's handset in every department, that it's probably not worth the money saved.
The HTC One sports a sophisticated and head-turning design, brighter high-res display, much better sound recording and output, as well as superior low-light camera footage. Thus one of the very few reasons to pick the S III before the HTC One is if you have to have a swappable battery and a memory expansion slot, in all other cases HTC's current finest is a clear winner before Samsung's last year bestseller, as can be expected.
