I'd say they execute so well it doesn't matter.
Isn't that what Samsung did by coming out with the bigger screened phones? Samsung knew the market was ready for bigger screens when Apple didn't think so, no?
Secondly - Samsung was forced to sell bigger screen phones because they couldn't achieve good battery life with smaller devices.
Not only that, Samsung was more profitable than apple for 2 consecutive quarters in 2013 before newer iPhones were released. Of course ton of other profits of samsung came from non-phones. http://www.businessinsider.com/samsung-is-now-a-more-profita...
Second, source on that battery story?
Samsung has defeated all old brands that attempted to survive by adopt android, but is now itself being defeated by cheaper new Chinese brands that can steal its low end share while Apple consumes the high end.
What is the point of mentioning Samsung's temporary high profits from other sources when we are discussing phone strategy?
But any how, what's your source for this statement: Secondly - Samsung was forced to sell bigger screen phones because they couldn't achieve good battery life with smaller devices.
