Never did had great relationship with my mobiles until I got IPhone 5S in my life 2 years back.
As said it is "The Wall" for me, as was Rahul Dravid, because all my phones used to loose their wicket for any normal external damage(robustness), used to get hanged when multi app were opened but Iphone just bats well even if forced to bat on different pitches with new ball at any given time, mean to say no matter how many apps are open, how long you work on it, it just bats all 5 days no more drain, no hang.
Frankly speaking as user I am not a good candidate for handling gadgets, but Iphone proved it the other way.
People often talk, Apple products are too hype for their money, but until you use it you will eventually experience that it is instead a true value for cost, no more time wastage to bang door of mobile repairer, no more switch off and switch on of mobile for every hang, saves times an instead saves money.
Frank advice, adding Iphone 5S in your life is just like adding Rahul Dravid in your team, will bat anywhere, will keep for you, just a selfless phone.
