The S10e is a brilliant phone, although there are some devices which offer slightly better value for money. However, this is how it stacks up:
Camera: With a 12MP dual aperture (f/2.4 and f/1.5) main camera with OIS and an ultra-wide angle lens, the S10e takes good photos in good and low light. The camera app also has scene optimiser and a night mode to help improve shots. Samsung’s noise reduction algorithms are sometimes over-aggressive, but either way the S10e’s cameras are great and better than the V30’s. The selfie camera is also pretty good, a big step up from the V30’s 5MP unit.
Battery: With a 3100mAh battery, the S10e has enough battery life to last all day (thanks to its smaller and lower-res screen and more efficient processor) but not more than that. So the battery life is solid/competent/adequate but unexceptional.
Display: Samsung displays are known to be the best in the industry. The 5.8 inch FHD dynamic AMOLED has a punch-hole to house the selfie camera and unlike the other S10s the display is flat with slightly thicker bezels. The display is excellent and the lower resolution isn’t something you would notice unless you look extremely close.
Performance: Packing a 7nm Snapdragon 855 with 6GB of RAM, the S10e has more than enough performance even for demanding users. Day-to-day usage and heavy gaming is handled pretty well, although extended periods with the latter may result in the phone warming slightly (and obviously drain the battery more than usual).
Other: The S10e has 2D facial recognition and a more secure (and interesting) side-mounted fingerprint sensor on the power button. Both work well. As usual, the S10e has an IP68 water resistance rating, headphone jack, expandable storage and stereo speakers. 15W Fast charging (both cable and wireless) is present along with Wireless PowerShare.
Hope that helps!
