OnePlus 2 vs OnePlus One: Camera
Like the OnePlus One, the OnePlus 2 includes a 13MP rear-facing camera with the ability to capture video at 4K and a dual-LED flash. Unlike the One, however, OnePlus has included optical image stabilization, or OIS, to help those with shaky hands. The inclusion of OIS has been a trend in the smartphone industry over the past year and it's nice to see that OnePlus hasn't ignored that. Users can also capture slo-mo video at up to 120 frames per second with a resolution of 720p.
Another improvement is the new low-light sensor found under the camera, which should help the sensor adjust to those low-light situations.
Last but not least when it comes to the rear-facing camera is the fact that OnePlus will be offering an update in the near future offering RAW image support. While the average user won't need access to such high quality camera data, the photographers among us will certainly appreciate it.
Selfie lovers will be happy to hear that the OnePlus 2 includes a 5MP front-facing camera, and while that is the same camera as its predecessor, that's not necessarily a bad thing, and should certainly be enough for Snapchat.
OnePlus 2 vs OnePlus One: Battery
OnePlus has included a slightly improved battery in the OnePlus 2, and with a display that's the same as its predecessor, a larger battery should directly translate to a longer battery life rather than simply the ability to power a higher resolution display.
While the OnePlus One included a 3,100 mAh lithium polymer battery, the OnePlus 2 includes a battery with a capacity of 3,300 mAh. This is a fairly large battery, and should last at least all day, even for the more active users among us.
OnePlus 2 vs OnePlus One: Operating System
OnePlus was rather famously known as one of the few device manufacturers to offer CyanogenMod out of the box, however, for the OnePlus 2 the company took things in a different direction, having developed its own operating system, dubbed OxygenOS.
Like CyanogenMod, OxygenOS is based on Android, and this version of OxygenOS is based on Android 5.1. OxygenOS is a little closer to stock Android than CyanogenMod, and offers a little less customization, however relative to CyanogenMod that probably won't affect most users.
