So I'm upgrading soon from my Lumia 520. Been using this phone for a year now. And I've been thinking about getting an iOS device instead of Android or WP. But I'm not sure if this phone is still good though. I heard lots of problems with the battery after the iOS 8 update and some slow downs and other problems. I don't want iPhone 5c or 5s or even the 6, their price in our country is ridiculous. What do you think guys? This could be my very first Apple device. Thanks!
