While Apple set the tone for premium, high-end smartphones with pricing to match, OnePlus is one of several companies trying to shake things up with flagship specs married to budget pricing. Let's see how the OnePlus 2 compares to the iPhone 6 Plus.
Size
The iPhone 6 Plus is 4 percent taller and wider than the OnePlus 2. The iPhone, however, is 28 percent thinner.
Weight
The iPhone 6 Plus is just 2 percent lighter, but since it's the bigger phone, the relative weight discrepancy will be a little wider than that.
Build (frame)
We've seen a recent trend in Android phones where their frame and backing are made of different material. In this case, the OnePlus 2 has a frame made of an aluminum/magnesium alloy.
"Frame" probably isn't the best description for the iPhone, since there's no separation: its entire body is carved out of a single piece of aluminum.
Build (back)
The OnePlus 2 ships with a sandstone back plate (likely a thin layer of sandstone on top of plastic), but you can also order natural wood or kevlar backs from the company's website.
Colors
That sandstone back on the OnePlus is black, but any of those alternative backings will also give you different colors.
Display size
Both handsets have 5.5-inch displays.
Display resolution
Resolution is also tied up, as we're looking at two 1080p screens.
Display type
It's three for three, as both phones share the key display specs.
Fingerprint sensor
We don't yet know if it stands up to the quality of Apple's Touch ID, but OnePlus did put a touch-based fingerprint sensor in its new flagship.
Storage
Internal storage options are even on the first two tiers, with the iPhone offering an extra 128 GB option.
MicroSD
Neither handset has any expandable storage options.
Processor
Performance isn't remotely an issue on the iPhone, with its speedy A8 chip, and we'd be surprised if there were any issues (except possibly heat output) with the OnePlus 2's Snapdragon 810.
RAM
The entry-level OnePlus 2 gives you 3 GB of RAM, while the more expensive 64 GB model jumps up to 4 GB memory.
Battery
We haven't yet tested the OnePlus 2's battery, but the iPhone 6 Plus dropped 12 percent per hour in our benchmark (streaming video over Wi-Fi, with brightness at 75 percent).
Removable battery
Both batteries are sealed shut, so there will be no swapping on the go with either phone.
Fast charging
Many recent Android flagships added a quick-charging feature (at least when the battery is nearly dead), but neither of these handsets offer anything like that.
Wireless charging
There's also no native wireless charging on either phone.
Camera megapixels
The OnePlus 2's rear camera has the higher resolution ... but the iPhone's photo quality is going to be tough to beat.
Camera aperture (rear)
The OnePlus' rear shooter has the wider aperture.
OIS
Both smartphones have Optical Image Stabilization for their rear cameras.
Notification toggle
The OnePlus 2 has a physical notification toggle that lets you switch among Android's three sound profiles: "All," "Priority" and "None."
Like older iPhones, the 6 Plus has a mute switch on its left side that lets you switch between audible and silent alerts (which can also include vibrate mode).
Charging/data cable
Both phones have reversible charging cables: Lightning on the iPhone, and the new USB Type C on the OnePlus 2.
Software
Much of the iPhone's spec-transcending experience comes from iOS, and its close ties to the hardware (no Android OEMs 100 percent design their phones' hardware and software from the ground up). But if you prefer Android, OnePlus gives you the pure version – its "OxygenOS" is nearly stock Lollipop, with just a few added tweaks.
Release
This isn't a great time to buy the iPhone 6 Plus, as we'll likely see a new model (iPhone 6s Plus, perhaps?) next month.
Order without invite
Only some people will be able to buy the OnePlus 2 on its August 11 "release date," as you need to sign up and wait for an invite before you can order the phone.
Starting price (full retail)
If you haven't yet seen a convincing reason to opt for the OnePlus 2, perhaps this will sway you. Though many iPhone buyers save upfront money by signing a contract or installment plan, the OnePlus starts at just US$329 with no strings attached.
