Here is a sum nobody prints. The OnePlus N6x 5G costs about Rs. 19,500 for 4GB + 64GB today. About Rs. 3,000 more buys its own sibling, the OnePlus N6, with 1,000mAh more battery, 3 times the charging speed, a 50MP camera in place of 13MP, and double the storage. And at the N6x's own price, another brand sells a 4GB + 128GB phone with a 7,900mAh cell and 45W charging. The N6x has honest strengths: 7,000mAh, IP64 with a military drop rating, a 3.5mm headphone jack and a microSD slot. It is simply the weakest-value way into its own family. Skip it.
A naming note: OnePlus now sells 3 phones in this series. The N6x is the 5G phone with the smaller battery. The OnePlus N6 is the 5G phone with the bigger one, and the N6 Lite is a separate 4G phone. Spec sheets mix them up constantly, so check the letter before you trust a number.
A practical phone, built for a hard life.
The battery is the point. 7,000mAh is a big cell to fit into a body 8.65mm thick and 214g heavy, and OnePlus adds bypass charging, which feeds power straight to the phone while gaming or navigating on a plugged-in cable instead of cycling it through the battery.
It is built for the scooter, not the showroom. IP64 covers dust and splashing water, and MIL-STD-810H adds a drop and stress rating. That combination matters more to a delivery rider or a monsoon commuter than an extra 20 nits of brightness ever will.
And it keeps 2 things that are vanishing. A 3.5mm headphone jack, so the wired earphones in the drawer still work, and a microSD slot up to 2TB. The card shares a tray with the second SIM, so you choose 2 SIMs or 1 SIM and a card, but the option is there. The screen is a 6.8-inch LCD at 120Hz, so scrolling is smooth even if text is not sharp.
15W, 64GB and 13MP, in that order.
The charging is the one that hurts. 15W is a basic-phone charging speed, and here it feeds 7,000mAh. OnePlus publishes no charge time for it, so we will not invent one, but the shape of the problem is plain: a big battery on a slow charger is a compromise, not a feature. This is a phone you charge overnight, every time, and a forgotten night costs you a morning.
The storage is the one you notice in month 6. 64GB, with the operating system taking its share, fills quickly with WhatsApp media alone. The card slot helps with photos and video; it does nothing for apps. The 128GB model fixes this and launched at Rs. 2,000 more, which puts it within about Rs. 1,500 of what its better-equipped sibling sells for today.
The cameras are basic. A single 13MP rear camera and a 5MP front camera are made for scanning documents and video calls, and video stops at 1080p at 30fps. The screen is HD+, 720 x 1570, so 254ppi on a 6.8-inch panel: fine for video, soft for reading.
And there is no promise. OnePlus has published no OS-update or security-update commitment for the N6x. An unstated policy is not a point in its favour, and on a phone people keep for 3 or 4 years, it is a real gap.
Rs. 3,000 more inside the family. Nothing more outside it.
OnePlus N6, about Rs. 22,500 for 4GB + 128GB today. Same chip, same 6.8-inch 120Hz screen, and then it pulls away: 8,000mAh against 7,000mAh, 45W against 15W, a 50MP f/1.8 main camera against 13MP, an 8MP front camera against 5MP, 128GB against 64GB, IP65 against IP64, and 1,200 nits in high-brightness mode against 900. It weighs 10g more. For about Rs. 3,000, that is a lopsided trade, and it runs entirely one way. Our OnePlus N6 5G review covers it in full.
POCO M8x 5G, Rs. 18,500 to Rs. 19,500 for 4GB + 128GB today, so the same money as the N6x with twice the storage. It carries a 7,900mAh battery with 45W charging, a 50MP main camera, an 8MP front camera, and a written promise of 4 Android upgrades and 6 years of security patches. It also launched at Rs. 20,999 and now sells below that. Our POCO M8x 5G review sets out what its screen costs you.
If you are tempted by the 4G version, read our OnePlus N6 Lite review first; the short answer is that 5G is worth having on a phone you will keep for years. For the wider field, our guide to the best battery life phones between Rs. 15,000 and Rs. 20,000 ranks the alternatives.
- You need a headphone jack and a microSD slot on a 5G phone
- Toughness matters more than speed: IP64 plus MIL-STD-810H
- You always charge overnight and never in a hurry
- About Rs. 3,000 more is within reach: the N6 is a different class of phone
- You want 45W charging and 128GB at this exact price
- You want an update promise in writing
Skip. On published specification the OnePlus N6x 5G is a sound, tough, practical phone with a big battery, a headphone jack and a card slot, and on its own it would be easy to like. It does not live on its own. About Rs. 3,000 more buys the OnePlus N6, which fixes the charging, the camera and the storage in one step, and the same Rs. 19,500 or so already buys a phone with a bigger battery, 3 times the charging speed, twice the storage and a 6-year update promise. Buy the N6x only if the headphone jack is the one thing you will not give up.
A sensible phone in the wrong family. The sibling is the bargain.
The price is for the base 4GB + 64GB model, read from live listings at 2 major Indian retailers on 11 October 2026; launch prices are labelled as such. Rival prices are live listings for each phone's base model, checked the same day. Specifications are confirmed against at least 2 independent sources each, led by the maker's own India specification. Where sources disagreed, such as the Bluetooth version, the speaker setup and the frame material, we left the claim out. Our verdict is based on published specification, not hands-on testing: we have not held this phone.
