If you're a OnePlus 2 owner who's been wondering whether the new model is worth the upgrade – or maybe you're torn between buying new and old right now – perhaps we can lend a hand. Join us as we compare the features and specs of the OnePlus 3 and OnePlus 2.
Size
Height and width are nearly identical, but the OnePlus 3 comes out 25 percent thinner.
Weight
The new model is also 10 percent lighter.
Build
The OnePlus 3 goes with what's now more or less the industry standard among flagships, an aluminum unibody design.
Last year's model had an aluminum and magnesium frame, but with interchangeable backs. It ships with a standard plastic one, but there are also bamboo, apricot, rosewood and kevlar options to choose from.
There's a similar setup for the OnePlus 3, but instead of new backs for the phone, they're protective cases made out of (some of) the same materials (plus "Karbon" and sandstone, and minus the kevlar).
Colors
The OnePlus 3 currently only ships in gray, though there's going to be a gold model at some point as well.
Last year's model shipped with that default black backing, though the replacements added two brown-ish colors and a couple of black-ish options.
Display size
No changes here, as OnePlus stuck with a spacious 5.5-inch display.
Display resolution
The company also stood pat with 1080p resolution. That's plenty sharp, though it does fall short of the ultra-sharp eye candy you get from QHD phones like the HTC 10 and Galaxy S7.
Display type
OnePlus switched from IPS to AMOLED with the new model.
Always-on display
Thanks to that AMOLED display, there's an option in the OnePlus 3 to have an always-on display, where time, date and other info show on an otherwise black screen.
Processor
The Snapdragon 810 still holds up well today, but we find 820 phones to be noticeably zippier. It also benchmarks quite a bit higher.
RAM
OnePlus went with an insane 6 GB of RAM in the 3. The OnePlus 2 originally shipped in 3 GB and 4 GB variants (tied to storage tiers), but it looks like the company now only sells the 4 GB model.
Storage
If you're buying either phone right now, then 64 GB is your only storage option, as OnePlus appears to have phased out that 16 GB storage/3 GB RAM version of the 2.
MicroSD
It's a good thing you get all that internal storage, because there's no expansion here.
NFC
Curiously, OnePlus left NFC out of last year's model – a questionable call, since mobile payments were starting to catch on right around then. The new model remedies that, and supports Android Pay.
Battery
The newer model has a slightly smaller battery, but that won't necessarily translate into shorter battery life. Stay tuned for our review for battery impressions.
Fast charging
Another missing piece from the OnePlus 2 was put in place with the "Dash Charge" feature in the OnePlus 3.
Wireless charging
There's still no wireless charging, though, on either handset.
Camera megapixels
Both cameras get a resolution bump; this is another one to watch out for in our review.
Camera aperture (rear)
No aperture change, though, could potentially mean low-lit photography doesn't drastically improve.
OIS
Optical Image Stabilization is still around for 2016.
Fingerprint sensor
No surprises here, as both phones have fingerprint sensors below their screens.
Water resistance
There's no water resistance on either OnePlus phone.
Charging/data port
The OnePlus 2 was the first big flagship to go with USB-C, and the new model sticks with the reversible standard.
Software
For a phone that runs a near stock version of Android, it took OnePlus an unusually long time to roll out the Marshmallow update to the OnePlus 2. It was stuck on Lollipop until about a month ago, eight months after Google pushed Marshmallow out to Nexus devices.
You might want to keep this in mind if you buy the OnePlus 3. Its software may look Nexus-like, but don't expect a Nexus-like turnaround after Android Nougat launches.
Release
The OnePlus 3 has been available since last month, and fortunately the company ditched its annoying invite system this time around. You can finally go online, order the phone and get it a few days later – no more gimmicks.
Starting price (full retail)
If you don't own either phone and you can afford that extra US$100, the OnePlus 3 is a faster, lighter and thinner phone with a higher-end design and a few other perks.
