Summary of iPhone 6 Plus reviews

For nearly a month, I've been using my iPhone 6 Plus every day. As one of the first users of such device in Korea, I decided to take an in-depth look at its improvements and functions whenever I can, to show what the Korean users are going to get soon. Now all the hard work is done, and I present to you the summary of all the reviews I wrote about it.

iPhone 6 series will finally launch in Korea officially on October 31, 2014, according to Apple's official announcement, and carriers are preparing to accept pre-orders about a week before that. I hope these reviews will help you decide if iPhone 6 Plus is right for you.

Unlocked iPhone 6 Plus bought overseas is found to have LTE working on Korea's SKT & KT networks automatically. Also, real life LTE speed comparison is made between the 6 Plus and the 5S.
5. iPhone 6 Plus - VoLTE Compatibility (2014-09-25)
Initially, all calls were made in 3G mode despite changing the settings to allow VoLTE. To have the VoLTE actually working, a visit to an SKT branch office and a device registration process was needed.
6. Testing iPhone 6 Plus battery w/o bending (2014-09-29)
Real-life battery discharging and charging tests are performed simultaneously on iPhone 6 Plus and iPhone 5S to see the difference. Belt cases made sure the phones didn't bend.
7. iPhone 6 Plus - General Performance (2014-10-01)
Performance comparison across multiple apps are made between iPhone 6 Plus and iPhone 5S. This included 3DMark, Geekbench, and various JavaScript tests.
8. iPhone 6 Plus - Camera's Quality (2014-10-01)
Compared to iPhone 5S, the camera on the iPhone 6 Plus has improved dynamic range and enhanced night time photography performance. Image stabilization works well, too.

10. iPhone 6 Plus - M8 Motion Co-processor (2014-10-08)
The M8 motion co-processor and its new barometer are tested out by walking up the stairs and seeing how many floors are registered. Other uses are also taken a look at.
11. How far does iPhone 6+ & SKT's VoLTE go? (2014-10-13)
How the SK Telecom's network treats the attempts to make a VoLTE call from iPhone 6 Plus varies by how the person at the other end is connecting. All the possibilities are tested.
12. Thoughts on a month of iPhone 6 Plus use (2014-10-14)
Using the iPhone 6 Plus one-handed is not as convenient as Apple would hope. However, the big screen that caused this also offers many benefits that maybe considered as worthy trade-offs.

iPhone 6 Plus - M8 Motion Co-processor

  
iOS 8's Health app shows the stair climbing recorded by iPhone 6 Plus

Last year, iPhone 5S came with a motion co-processor called M7 that can collect various sensor data relating to iPhone's motion. The most notable use for this was recording how many steps a user took while carrying the device. In other words, the device acted as a pedometer. This year, iPhone 6 series has updated the co-processor to M8 and added another sensor - a barometer. The Health app that comes with iOS 8 makes an immediate use of this. It records how many floors the user has climbed, adding another dimension of knowledge to the user's movement.

Apps that are updated to use the Healthkit in iOS 8, such as Argus, can read this stair climbing data. The notification widget from Argus is able to display the number of floors I moved up during the day if I'm using an iPhone 6 Plus. If I'm using an iPhone 5S, there's no such data available, so the widget simply doesn't mention it at all.

While I'm comparing the data from both devices, I should note is that the pedometer function acted very similarly between each other. However, as you can see in the pictures, iPhone 5S consistently recorded a bit more steps than iPhone 6 Plus, for some reason. Perhaps the bigger form factor and weight of the 6 Plus dampened the recorded movement a bit.
