POCO M8x 5G Launches Today in India: 7,900mAh Battery, Price and Specs

POCO’s M8x 5G launches in India today, August 21, 2026, at 12 noon — and the pitch isn’t a flashy camera or a huge display, it’s a 7,900mAh battery POCO claims delivers three full days of use. The phone goes on sale exclusively through Flipkart, and POCO has already confirmed the core specs itself, which is more than I can say for most of the “leaked ahead of launch” phones I write about — this one, the company put the real numbers out early instead of letting rumor sites guess.

I’ve covered a run of budget-to-midrange Indian launches this month — the iQOO Z11’s Dimensity 7500 Turbo push and vivo’s S2 going on sale — and the M8x fits the same pattern: brands in this segment have mostly stopped competing on raw specs and started competing on the two things people who keep a phone for three years actually notice, battery life and how long it gets updates.

What POCO has officially confirmed

The headline number is the 7,900mAh battery, paired with 45W wired charging and 22.5W reverse wired charging — meaning you can top up another device off the M8x in a pinch. POCO says that battery is good for roughly three days of typical use, a claim I’d treat the way I treat every “X days of battery” marketing line: plausible for light use, optimistic for anyone who actually games or streams video on the thing.

Powering it is Qualcomm’s Snapdragon 4 Gen 5, built on a 4nm process, with POCO citing an AnTuTu score north of 650,000 — respectable for the segment, though AnTuTu numbers are best read as a rough ranking tool rather than a real-world performance guarantee. RAM tops out at up to 12GB, with 6GB of that coming from virtual RAM expansion (borrowed storage, not physical memory) layered on top of 6GB of actual LPDDR4x, and storage runs UFS 2.2.

POCO also confirmed a triple-layer cooling system — a 12,439-square-millimetre graphite sheet, a 1,924-square-millimetre copper foil layer, and thermal gel — aimed at keeping the Snapdragon 4 Gen 5 from throttling under sustained load, which matters more on a budget chip than a flagship one since there’s less thermal headroom to begin with. Build-wise, the M8x gets IP64 dust and splash resistance and Corning Gorilla Glass 7i on the display, both genuinely useful inclusions at this price point that budget phones skipped just a couple of years ago.

The software commitment is the other half of POCO’s pitch: four years of Android OS upgrades and six years of total software (security) updates. That’s a meaningfully longer support window than this segment used to offer, and it’s the kind of spec that only matters in year three when a cheaper competitor has already stopped getting updates and yours hasn’t.

What’s still unconfirmed at launch

A few widely-reported specs haven’t come from POCO directly and are still sitting in leak territory as of this writing: a 6.9-inch 120Hz LCD display and HyperOS 3 (built on Android 16) are the most consistently repeated figures across the Indian tech press, but neither has appeared in POCO’s own confirmed spec drops the way the battery and charging numbers did. I’m treating the display size and refresh rate as likely-but-not-yet-official until POCO’s own listing goes live at noon.

Pricing is the biggest open question. POCO hasn’t announced a number, and estimates cluster under Rs 20,000 — but that figure deserves some skepticism. The M8x sits directly below the POCO M8 Power 5G, which launched earlier this month at Rs 24,999, and the M8x runs a newer-generation chipset (Snapdragon 4 Gen 5 vs. the M8 Power’s older silicon). A meaningfully cheaper price on newer silicon is possible, but POCO undercutting its own recent launch by five-figures worth of rupees while using a newer chip is the kind of gap that tends to close once the actual number lands. Worth checking POCO’s Flipkart listing directly once the event wraps rather than trusting the pre-launch estimate.

Where it fits in POCO’s lineup

POCO has been unusually active in India this year, and the M8x slots into a family that already includes the standard M8 and the higher-spec M8 Power. The strategy looks deliberate: use the “M” series to blanket every price band under Rs 25,000 rather than picking one sweet spot, forcing budget shoppers to compare POCO against POCO instead of drifting to Redmi, Realme, or iQOO. Whether that’s smart segmentation or cannibalization depends entirely on where the M8x actually lands once pricing is public — a phone with a bigger battery and newer chip priced too close to the M8 Power would eat its own sibling’s lunch.

Should you wait for the price before deciding?

If you’re shopping this segment right now, yes — wait the few hours until POCO’s Flipkart listing goes live rather than pre-ordering blind. The confirmed specs (battery, charging, chipset, durability, software support) are genuinely strong for a sub-Rs 25,000 phone, but a phone’s value proposition in India’s budget segment lives or dies on the final price tag relative to what else is available that week. The iQOO Z11 launched days ago in a similar bracket with a 144Hz curved AMOLED display and a larger 7050mAh battery; if the M8x’s LCD display rumor holds up, POCO is betting that four extra years of software updates and a bigger battery buffer will outweigh a lower-refresh, lower-resolution screen for buyers who keep phones long-term rather than chase spec sheets. That’s a reasonable bet for the “I want this to still work fine in 2030” crowd, less so for anyone who cares about display quality day one.
