The HTC One A9s is just one of those entry-level phones that's hard to get excited about. Announced at IFA, the One A9s is essentially a downgraded version of the One A9 designed to hit a lower price point.
The 5.0-inch 1080p AMOLED has been swapped out in favor of a 5.0-inch 720p LCD, while the SoC gets a notable downgrade to a MediaTek Helio P10 from a Qualcomm Snapdragon 617. The One A9s also packs 2 or 3 GB of RAM depending on whether you get the 16 or 32 GB models, and there's microSD card storage as well.
The camera is nothing remarkable: a 13-megapixel sensor with an f/2.2 lens; there's no OIS here, unlike the standard One A9. The entire phone is thicker and heavier, although that allows HTC to cram in a 2,300 mAh battery rather than the tiny 2,150 mAh cell in the A9. Connectivity-wise there's a fairly typical arrangement, including Cat.6 LTE and dual-band Wi-Fi 802.11n.
HTC hasn't said exactly how much the One A9s will cost, but it will be significantly cheaper than the One A9's $499 launch price. Renders of the One A9 suggest that the phone will hit the market on October 14, although HTC again hasn't confirmed any specifics here.
