POCO X8 Power 5G Review: 10,000mAh, Four IP Ratings, and Wi-Fi 5

There is a buyer Indian phone reviews almost never write for. They are outside most of the day. Their phone is a torch, a map, a payment terminal and a camera, in rotation, in sunlight, often with wet hands. They do not care what a benchmark says and they care enormously whether the thing survives to 8pm without being nursed.

The POCO X8 Power was announced on 4 September 2026 and went on sale here on the 11th, at Rs. 35,999 for 8GB with 128GB and Rs. 38,999 for 8GB with 256GB. Those are launch prices and we are labelling them as such. The one live listing we could read was still sitting at Rs. 35,999 3 weeks later, but we could not confirm a second independent retail listing, so we are printing the figure the maker announced rather than dressing a single reading up as a market band.

10,000mAh, 8.65mm thick, 229 grams.

Take those 3 numbers together rather than one at a time, because separately they are unremarkable and together they are the entire phone.

A 10,000mAh cell used to mean a slab you could stun a burglar with. This one sits in a body 8.65mm thick weighing 229g. The trick is silicon-carbon chemistry, which packs more energy into the same volume than the graphite cells most phones still use, and it is the single most consequential thing to happen to Indian phones in 2 years. 15 months ago this capacity in this thickness was not on sale at any price.

Then it fills at 100W. That combination is the part worth pausing on, because big battery and slow charging is the compromise this category usually asks you to accept: you get 2 days of use and you pay for it with 2 hours on a wall. Here you get neither half of that bargain. It also gives power back out over a cable, which on a 10,000mAh phone is less a party trick than a genuine function - this is a phone that can keep somebody else's phone alive on a long day.

That works out to better specified than 82% of the 206 phones we track on sale in India, and it is one of the most lopsided sets of bars we have printed. 98th percentile on battery and 95th on charging, 7th percentile on one-handed comfort. A phone can be near the top of the market and still be a bad fit for you, and this is what that looks like on a chart.

IP66, IP68, IP69 and IP69K. That is not a typo, and it is not 4 ways of saying one thing.

Manufacturers list these in a row and readers skim them as decoration. They are four different tests and they earn different things.

IP66 is powerful water jets. IP68 is dust-tight plus sustained immersion. IP69 and IP69K are the interesting ones: high-pressure, high-temperature steam cleaning, a standard written for industrial equipment and farm machinery rather than for consumer electronics. A phone carrying that rating is one you can wash under a tap after a day on a site.

At Rs. 35,999 this is the most over-engineered thing on the sheet, and unlike a benchmark score it is the kind of over-engineering you will feel on exactly the day you need it.

A Snapdragon 6 Gen 5, on a phone that costs Rs. 36,000.

Now the bill.

The Snapdragon 6 Gen 5 is a capable, efficient 4nm upper-budget chip, and it is the right chip for a phone that has to make a huge battery last. It is not the chip this price bracket normally buys. Around Rs. 35,000 the Indian market's default answer is a considerably faster part, and if you rank phones by what their silicon can do, this one will finish a long way down a list it is priced near the top of.

Two more things follow the same logic and are harder to defend. Wi-Fi 5 in 2026, on a phone whose own chipset can do better, is a specification from another decade - it caps what you get out of a fast home connection, and it is the kind of corner that costs a maker very little and costs a buyer for years. And there is no card slot, so 128GB is 128GB for the life of the phone, which on a device promised 6 years of patches is a real constraint rather than a footnote.

Better than the price suggests, and smaller than the box suggests.

The display is the quiet win. 6.83 inches of AMOLED at 1280 x 2772 works out to about 447 pixels per inch, which is genuinely sharp rather than the 1080p-class panel this segment usually settles for, and it runs at 120Hz. Resolution and refresh rate are independent facts and most phones at this money only give you the second one. Our display guide explains why the first one is the harder thing to buy.

The cameras are where a battery phone usually falls apart, and this one does not, quite. A 50MP f/1.5 main with optical stabilisation is a serious lens for the segment, and f/1.5 is a wide aperture by any standard. Beside it sits an 8MP ultra-wide, and that is the whole set. Two cameras, both of which do a job.

We want to be clear that this is a point in its favour. A maker chasing a bigger number on the box would have bolted a 2MP macro on the back and called it a triple camera. POCO counted to two and stopped, which is the more honest arithmetic and, on the evidence of our guide to camera specifications, the better photographs.

Against its own sibling, and against the phones its price actually puts it beside.

The most useful comparison is inside the family. The standard POCO X8 5G arrived the same week at Rs. 29,999 with a smaller battery, a slower charger and a lesser chip. Rs. 6,000 buys you the extra capacity, the 100W charging and the better silicon, and if endurance is the reason you are on this page, it is money well spent. If it is not, the cheaper one is the more sensible object. The POCO X8 Pro is the other direction entirely: the performance phone in this line.

Outside the family, the phone that makes the same argument even harder is the realme P4 Power, which carries a slightly larger 10,001mAh cell behind a 144Hz panel of much the same sharpness, charges at 80W rather than 100W, and launched substantially cheaper. Whether it is still cheaper on the day you shop is a question worth asking at the listing rather than taking from us, because that phone has been drifting upwards all year.

The harder comparison is the Motorola Edge 70 Fusion, and we are not going to soften it. It launched in March at Rs. 26,999 and its maker has since raised the list price to Rs. 33,999, so treat both numbers as list rather than as what you will pay. It is rated IP68 and IP69, it runs a 7,000mAh battery at 68W, it carries a Snapdragon 7s Gen 4 - a genuinely quicker class of chip - and it weighs 193g against this phone's 229g. So the X8 Power's real advantage over it is 3,000mAh, a faster charger and the steam-cleaning rating. Everything else on that list runs the other way. If you want the endurance without the weight and without the chipset compromise, that is the phone to look at first, and our battery guide one band down has the rest of the field. And if your budget sits right at this phone's price, our POCO X8 Power vs vivo T5 comparison weighs it against a lighter phone at almost the same money. Xiaomi also sells a near relative, the Redmi Note 17 Pro 5G, with this phone's screen and ratings but a smaller battery and slower charging, and our Redmi Note 17 Pro 5G review sets the 2 side by side.
