Current iphone X user. I am sending in my iphone X today to apple via fedex for a replacement, so itll take a few days for them to get it, and then a few days to get my new one shipped to me.. plus weekend doesnt count.. Got me thinking of having a backup iphone. I have a galaxy S8 laying around ( wll give to family member soon) but being out of the eco system is terrible. Most of my work related messages are all imessage groups and also my apple watch wouldnt work. I have an iPhone 4S laying around and im trying it now, and i got almost all my usual apps installed minus Apollo, but performance is just soooooooooooooo slow. Also cant use apple watch with 4S. Also i usually trade in my phone to apple when i get a new phone just because i dont want to buy the newest iphone and then sell later , or sell before the new one launches and be without a phone. Having a better iphone backup (but still budget option), in case of emergency, problems with main phone, or simply being able to use backup iphone while i sell my main one when i upgrade would be nice. So i was thinking of the iphone SE, can anyone chime in with experiences using it on the latest ios?
