As Android updates improve speed and battery life, iOS updates suck your battery life and lag your phone to gingerbread-levels.
isnt that same was mentioned for ics , jellybean, kitkat and lollipop????
Focus on battery, how exactly? B ecause with 5.1, they were focused on worsening battery life, despite their blagh-blah hollow claims. So should we expect even worse battery life or it will just be fixed bato to kitkaty levels
They said same about Lollipop and we know how it ended. Ask S4 users...
