I have both an iPhone 6 and 6 plus love the battery life of my 6 plus but way too many lag issues anyone else? I'm thinking of returning it and getting another iPhone 6 plus or will I just have the same issues? This thing is acting like a droid
No prob, many software issues are attributed to faulty old backups used on previous hardware devices or created under older ios versions etc...
Give it a try for a few days setup as new and if it still freezes or lags bring it to Apple for replacement.
