People complaining about the weight of the XR: It's literally .7 oz heavier than the iPhone X. It's not that heavy. it has a bigger battery and the longest battery life of any iPhone ever released, getting 3 hours more internet use and wireless video playback than the X. Heck the iPhone 8+ is 7.12 oz and its screen is .6" smaller than the XR (albeit a higher dpi display).
Seems Apple can't win. Smaller battery, lighter phone = "battery life sucks!" Bigger battery, better battery life = "OMG I can barely lift it!"
