I am using this phone. It is really very fast I have never experienced any issues in this phone. It is really worth money. Games and other apps can be run smoothly. We will never experience any issues with this phone. Thats a guarantee. I never had lag or slow down while playing PUBG. Thanks to APPLE. They are not going to settle down on performance. It has a good battery. I have never experienced any heat problems or battery drain problems. Such a good phone to trust on. It provides ?? security rather than any other phones.
