I have used the S6 Edge for 3 year before getting the new S9+. My experience with the phone was a delight. The phone has great features and an amazing display. It is fast, has decent amount of storage, a good battery and Fingerprint sensor. The only drawback I could notice on the phone is the battery life. It wouldnt last the entire day with use and almost always died at the end of the day just before reaching home. Also the lack of extendable memory is infuriating. The fast charger is great as it chargers the phone quickly and the camera clicks decent pics.
This is the 1st model Samsung had brought out which couldnt be opened from the back which had its drawbacks due to the poor battery performance. Also the phone had a full glass body which collects fingerprints but it is really useful as the phone did not break even after repeated falls, the highest being from 8 feet. The cover for the phone is great which has a see through from which is very handy.
Over the phone is a great one to possess considering its now more than 3 years old and yet performs very well and lasts long.
