I am writing this review after using the phone for 2 years. First year, the performance of the phone was not comparable to any phone, it was just fabulous. The camera quality was also awesome, the resultant picture use to be perfect. The working speed of the phone was also perfect. The battery life of the phone was also good, a full charge was giving a working time of around 10hours with WiFi connected and bluetooth disconnected. As the time passed and many updates came, the speed of the phone went on decreasing day by day. These days, the phone’s software has been updated to iOS 11 and from then the phone is acting like an ordinary android phone which takes 10 seconds for each function to perform. Apple has made a disgusting decision of updating the software and slowing down the machine so that the people upgrade from this phone to apple’s higher models like iPhone 8 and iPhone X.
The worst mistake I did was buying a 16 GB variant, because it is so difficult to clean your phone every time. Whenever you are stuck somewhere for work, the phone will give a message to manage your storage as the iPhone is out of memory. If you are an Apple fan, make a rule that always buy a variant above 64 GB else you will always be engaged in cleaning up the memory by deleting photos, whatsapp chats, videos, apps, and much more. At this point of time I would not recommend you to buy this phone because of speed issues.
