Lagging

Ive been plying future fight for over a year and havent complained until now. Lately Ive been getting lagging and freezing problems, but I try to convince myself its my iPhone7. Today I realized its the game because during a "Boss Invasion" the game froze and had to restart the game. In the beginning, my energy was at about 356 and after the freezing problem my energy dropped to 108 energy. Currently Im level 56 meaning a regular full energy bar is set to 108 therefore I lost all the extra energy I was storing up! That right there got me mad! Can the creator get back at me. Its not fair man that this has to happen. I love the game But a bit disappointed. Thanks for reading.
