So.... I've always had an iPhone since the iphone 3. I tried to use a Samsung Galaxy skyrocket and that was not a pleasant experience then ended up going back to the 4s after a weekend. Needless to say making this purchase of another android phone came with some hesitation. I've had the iPhone 6 since launch and with its upgrades I still felt like I longed for something more or something different. After seeing early reviews on the z3c I felt like it was my dream machine but still skeptical. I've used the ip6 for almost 2 weeks but now using the z3c for about 3 days and this is my comparison: Camera iPhone 6 camera is amazing. Everything stays true to color and the definition is great. The z3c is also very nice with many more options but it does take some skill to take a perfect shot. Playing with settings is key. Slightly better camera on ip6 but not huge deal for me as I've taken side by side pics with both and have had mixed outcomes. Speaker Ip6 speaker is louder than the 5s was, making it a good upgrade. The z3c is just as loud but you are listening in stereo due to the dual speakers and they are placed in a better location. Even like this there can be a muffled sound on certain audio files but it really depends. I would say sound is even. Form factor The z3c has pretty much the same size screen as the ip6 but a lot less form factor due to the beautiful bezels. You can use the z3c very easily with one hand just we did with our iPhone 5. It feels nice and heavy and it screams quality as well. To me the z3c feels just as premium and more comfortable than the ip6. Screen display The z3c looks as good and to me better than the ip6. Brighter beautiful colors I am not accustomed to being new to android phones. The resolution specs mean nothing in this comparison it's a stalemate. Either way you can't go wrong but I slightly prefer the z3c in this. Processing power etc. Both phones are fast. The only thing I've noticed is that scrolling through Facebook and Instagram is more fluid on the ip6. Why is there still some studder on these android phones? It's not a deal breaker by any means but there is a difference to get used to. Gaming, there is no difference. Browsing is the same on both... Fast. No issues with ram on either. 1gb v 2gb blah blah blah. No difference. Battery Ip6 battery is good. I can go a full day on normal use. The z3c battery is bigger, a good amount bigger. Yesterday I left to work on a 89% charge. Played my vegas on lunch, browsed Facebook off and on as well as Instagram and flipboard throughout the day. I got home around 7 pm and played music throughout an hour workout on pandora. At MIDNIGHT I started to download 30 free songs on an android app that added these songs straight to my music app (amazing to me,no need to use iTunes) I was also streaming song previews while they were downloading. After all this I still had 20% left on the battery at bed time. So the z3c battery is very good. Do not think your going to get 2 days out of it though. It will give you one full day easy no matter what you throw at it. What do I miss from the ip6? Fingerprint scanner. The apps seem to be a bit better quality from the App Store. The easy use of the camera and scrolling on Facebook that is so fluid. iMessages What do I like on the z3c? Form factor, waterproof, speakers. I love that I can customize more and download music straight to the phone. I like the led notification light so no need to turn on the phone to know if I got a text or email. Double tap screen to wake. Conclusion: You can't go wrong with either but surprisingly.. I am using the z3c and I have not gone back to my ip6 like I thought I would right away. Is it because it's something new? Is it the form factor. No clue, but I do know that's its a beautiful device and the ip6 is no longer the only choice on premium devices. Both are awesome, my problem is now... Wth do I do with two phones I can't choose between?
