Two phones launched at effectively the same price. One of them is still there. The other drifted up by Rs 12,000 and now wants to fight above its weight. That is the whole Realme GT 8 Pro vs OnePlus 15 comparison in two sentences, so here is the short answer: buy the Realme GT 8 Pro. It has the better cameras, the sharper display, and the honest price. OnePlus is left winning the rounds that matter less to most people.
Now the working.
The Rs 12,000 problem
Beebom lists the OnePlus 15’s starting launch price at Rs 72,300. Today the same phone sells at Rs 84,999, and Beebom says it plainly: Rs 12,000 higher than launch. OnePlus’s own festive sale (announced October 8, per Telangana Today) had the 12GB/256GB at Rs 84,999 with up to Rs 3,000 bank discount, a net Rs 81,999. The Diwali offers confirmed the same math: regular Rs 85,999, sale Rs 84,999 (Times of India, October 22).
The Realme GT 8 Pro never left the station. 91mobiles lists the 12GB/256GB at Rs 72,999 on Flipkart, updated October 23, with the 16GB/512GB at Rs 78,999. So the gap on the shelf is about Rs 12,000, a gap the launch prices never had.
That price hike is not an OnePlus quirk. Every flagship got more expensive this year and every brand is happy to blame memory chip costs, including ours: our OnePlus 16 China launch story notes the new flagship costs 50 percent more than the 15 did at launch. Convenient, that. But blame does not change the math for the buyer holding two phones side by side.
Realme GT 8 Pro vs OnePlus 15: cameras
This is the round that decides the comparison, so it gets its own section.
Realme went to Ricoh. The GT 8 Pro’s triple setup is a 50MP main with anti-glare coating, a 50MP ultrawide, and a 200MP periscope telephoto stretching to 120x digital zoom, co-tuned with Ricoh GR and loaded with five film presets (NDTV Profit). A dedicated HyperVision AI chip handles imaging, and 91mobiles’ review calls the phone “a fresh take on flagship design and photography.”
OnePlus went the other way. The 15 carries three 50MP sensors, the telephoto at 3.5x, with no Hasselblad branding and a new DetailMax processing engine that QuickTechnos lists as “still in its infancy” among its cons. Their verdict is blunt: “camera performance is not the best in class.” MobDeck’s aggregation of YouTube reviews lands in the same place: excellent for gamers and heavy users, but “camera downgrades… may disappoint those prioritizing photography.”
One brand invested in photography. The other visibly disinvested. Camera winner: Realme, and it is not close.
The swappable camera module deserves one honest sentence. It is a launch-week party trick, fun to show friends, forgotten by the second month, and Realme knows it, which is why the actual cameras underneath are good enough to carry the phone after the novelty wears off.
The rounds OnePlus still wins
Credit where it is due. Both phones run Qualcomm’s Snapdragon 8 Elite Gen 5 (Beebom, 91mobiles), but OnePlus pairs it with years of gaming-first tuning and a 6.78-inch 1.5K AMOLED at 165Hz. Gadgets360’s summary is fair: flagship-tier performance, a massive 7,300mAh battery, and if “sustained flagship performance and multi-day battery life are your priorities, then the OnePlus 15 is a no-brainer.” 91mobiles’ expert review scores it 8.4 out of 10. Software is OxygenOS 16 on Android 16 (Beebom), which still has the cleaner reputation of the two, and the battery beats Realme’s 7,000mAh. Both charge at 120W with 50W wireless. Battery winner: OnePlus, narrowly. Software: OnePlus, on reputation.
Where the Realme answers back
The display is the honest swing round. Realme’s panel is a 6.79-inch QHD+ at 144Hz pushing 7,000 nits peak brightness (NDTV Profit). OnePlus’s is 1.5K at 165Hz. Nobody’s eyes can tell 144Hz from 165Hz, but everybody’s eyes can tell 1.5K from QHD+. Gadgets360 called the 2K-for-165Hz tradeoff “a misstep.” Display winner: Realme, on resolution.
And then there is the money. Realme is roughly Rs 12,000 cheaper for 12GB/256GB, and its battery instinct runs deeper in the brand: our Realme P4 Power review covered the 10,001mAh phone that set Realme’s battery-first reputation. OnePlus’s official sale price leaves the 15 fighting phones it was never meant to fight, like the iQOO 15 at Rs 72,999 for 12GB/256GB (Gadgets360), which is sitting exactly where the OnePlus 15 used to be.
The verdict: who buys what
No fence-sitting. Category by category: price and value goes to the GT 8 Pro. Cameras go to the GT 8 Pro, decisively. Display goes to the GT 8 Pro, on resolution. Performance for gamers goes to the OnePlus 15. Battery goes to the OnePlus 15, narrowly. Software goes to the OnePlus 15.
The overall winner is the Realme GT 8 Pro. Four rounds to three, and the four it wins are the ones most buyers actually feel: the price on the shelf, the screen in front of their face, and the camera that captures their kid’s birthday.
Buy the GT 8 Pro if you want the best cameras Rs 73,000 can buy, if you notice screen sharpness, or if the idea of paying Rs 12,000 extra for the OnePlus badge annoys you as much as it annoys me.
Buy the OnePlus 15 if you game hard enough to feel the difference between good and elite tuning, if OxygenOS is the reason you stayed with OnePlus this long, or if that 7,300mAh battery is the feature your day is built around. You are paying the premium and getting an excellent phone, just not the better deal.
If Rs 73,000 is more than your budget allows, our Oppo F35 Pro vs OnePlus Nord 6 comparison settles the Rs 40,000 fight, and our OnePlus 16 China launch story shows what OnePlus thinks flagship money looks like now.
