The HTC One M8s is an upgraded version of One M8. The One M8s has corrected whatever was wrong with One M8. One M8s has borrowed it's stylish design from its ancestor One M8. It has a new processor, larger battery and better camera, and all this upgradation for lesser money than One M8. But these upgradations do not necessarily mean that it performs better than One M8. Its performance is a matter of concern. The camera performance is not good, and the new processor eats up the battery. Let us look at the various features of this phone in depth.
The HTC One M8s has the excellent design of HTC One M8. On first look, the M8s looks exactly like the M8, but M8s is a shade thicker by 0.2 mm than M8 at 9.6 mm. The difference is marginal, and you might not be able to notice it with the naked eye. The One M8s has bruised aluminum back and feels great in the palm. It is a little bit heavier and chunkier than the most manufacturer’s high-end phones, but its design copes with that. The phone comes in gray, silver and gold. The design still has a flaw. The power button is positioned at the top, rather than the side. It is a big phone and by placing the power button at the top, it has become a bit more uncomfortable. However, HTC has tried something else as a partial save to that flaw. You can turn on the phone’s screen by double tapping, of you switch on the gestures. But still, the power key on the side would have been great. It seems like HTC has used some leftover parts from the One M8. On both the sides, there is pop out trays. The left one is the nano SIM, and the right one holds the microSD card.
The display on this device is a 5 inch, 1080p LCD. The colours on this device look a bit over saturated. The skew isn’t perfectly managed. The green tones emphasized more than the other colours. Also, there are no controls in the settings to tweak the saturation of colour tone. Other than that, the image quality on this display is good. The outdoor visibility is quite good, thanks to the bright display backlight. The HTC One M8s uses SLCD2 panel, and Gorilla Glass 2 protection, both of them feels outdated as much better versions are already available in the market. However, the viewing angles are good in this phone’s display.
The HTC One M8s runs on Android Lollipop 5.0.2, with HTC Sense 6.0 tweaked on it. The Android version is updated, but the HTC’s custom interface is one generation behind. HTC Sense 7.0 is already available on other HTC devices. The phone has a mid-range chipset, Snapdragon 615 processor. The GPU used is Adreno 405. These are lesser specs in comparison to M9 or M8, but they do not matter. They power the phone enough to make it run seamlessly. It supports top-end Android games at 1080p. However, the benchmarks results are not better than M8 series. It scores 2455 in Geekbench 3, while the M8 scored 2700, but the difference in power is greater than this may suggest.
The phone is 4G compatible and supports GPRS and EDGE as well. The CPU uses Quad-core 1.7 GHz Cortex-A53 & Quad-core 1.0 GHz Cortex-A53. The internal memory is 16GB / 32GB, along with 2GB of RAM.
HTC One M8s uses a 13 MP rear camera and a 5MP front camera. This type of camera specs is usually available in affordable phones. The Sony sensors which are used by most of the affordable phones having 13 megapixels camera, is used here as well, which makes the images look perfectly normal. The zoomed in images look a little noisy, which results in fine details to look stressed. The camera also struggles to get the exposure right. Overall, the primary camera quality on One M8s is not as good as we expected for a 13 MP camera. The app is also not well organized. To activate HDR, it needs three taps. The app does not use the space productively. Also, the front camera is not much good. The front camera quality is equal to some 2 MP selfie cameras.
HTC has used BoomSound speakers here, which are great. The speakers are placed at the front. The music player is also good. You can tweak the sound of any song using the BoomSound EQ mode. It is good for listening to music on speakers, but not good for headphones.
The battery used on this phone is a 2840mAh battery, which sounds good for a 5" 1080p phone. But it isn’t. The stamina of HTC One M8s is poor. You need to charge it at least once a day. The phone’s battery will die by the evening every day. At first, we thought that there was a need for some update or some errant app was sucking up the battery, but it was all alright. The stamina itself is weak. To test the stamina, we played a 90 minute 720p MP4 video, and it ate 30 % of battery. The main reason behind such poor battery performance is the processor. This chipset has some heat and efficiency issues. Also, the screen is SLCD2, which is not as efficient as SLCD3, which was used in One M8. You can try to save some battery by using extreme power saver mode, which changes the UI leaving you with access to basic phone features.
