The POCO X8 Power is one of the most unusual mid-range smartphones launched in India this year, not because of its display, camera or processor, but because of one specification that immediately stands out: a 10,000mAh battery.
POCO launched the X8 Power in India on September 4 at a starting price of ₹35,999, with an effective launch price of ₹32,999 through introductory offers. The phone will go on sale from September 11. (91mobiles)
The battery is paired with 100W wired charging, a Snapdragon 6 Gen 5 chipset and a 6.83-inch 1.5K AMOLED display, according to Gadgets 360’s launch coverage.
On paper, that sounds impressive.
But there is a more interesting question than simply asking how large the battery is:
Does a 10,000mAh battery actually make sense in a phone you have to carry every day?
A 10,000mAh Battery Changes the Use Case
Most mainstream smartphones have spent years around the 5,000mAh mark.
The X8 Power effectively doubles that familiar capacity.
POCO uses a silicon-carbon battery, which allows manufacturers to increase energy density without making the phone proportionally thicker. 91mobiles lists the X8 Power at around 8.65mm thick despite its 10,000mAh cell.
That is probably the most important engineering achievement here.
A few years ago, a phone with this capacity would likely have looked and felt like a specialist rugged device.
The X8 Power still looks like a conventional smartphone.
The Trade-Off Is Weight
There is no escaping physics completely.
The X8 Power weighs around 229g, according to Gadgets 360’s India specifications.
That makes it noticeably heavier than many mainstream phones.
Whether that matters depends heavily on the user.
For someone who spends most of the day near a charger, carrying extra weight for a battery this large may feel unnecessary.
For a user who travels frequently, games for long periods, records video, uses 5G heavily or spends long hours away from power outlets, the trade-off may make much more sense.
That is why the X8 Power should probably be judged less like a conventional mid-range phone and more like an endurance-focused device.
The Real Test Will Be Two-Day and Three-Day Use
POCO has promoted the X8 Power around extreme endurance, but manufacturer battery-life claims should always be treated as controlled-test results rather than guaranteed real-world figures.
The more useful questions for an actual review are:
Can it comfortably last two full days of mixed use?
Can heavy users get through a full day without worrying about charging?
How much battery does an hour of gaming consume?
How much standby drain occurs overnight?
How much does 5G affect endurance?
Does the phone remain cool during long use?
A 10,000mAh number is impressive, but optimisation matters just as much.
A poorly tuned phone with a giant battery can still disappoint.
100W Charging Makes the Huge Battery More Practical
One obvious problem with a battery this large is recharge time.
POCO addresses that with 100W HyperCharge, while the phone also supports 27W wired reverse charging, according to 91mobiles.
That faster charging support is important.
A huge battery paired with 25W or 33W charging could be frustrating because a full recharge might take a very long time.
100W does not automatically mean every charging session will sustain maximum power throughout the process, but it gives the X8 Power a much better chance of remaining practical in everyday use.
A proper review should test:
Those results matter more than the headline 100W number.
Reverse Charging Could Be More Useful Than Expected
The X8 Power’s 27W reverse charging is another feature that makes more sense because of the huge battery.
A 10,000mAh phone can effectively act as a small emergency power bank.
That could be useful for charging:
For many users, reverse charging on a normal 5,000mAh phone is something they rarely want to use because it sacrifices too much of their own battery.
The X8 Power has enough capacity to make the feature genuinely practical.
Snapdragon 6 Gen 5 Looks Sensible Rather Than Exciting
The phone uses Qualcomm’s Snapdragon 6 Gen 5, paired with LPDDR5X memory on supported configurations. Gadgets 360 lists the chipset as a 4nm platform with clock speeds up to 2.6GHz.
This is not a flagship processor.
That may actually be a sensible choice.
A battery-first phone does not necessarily need the most power-hungry flagship silicon.
The important thing will be whether the Snapdragon 6 Gen 5 delivers enough performance while keeping thermals and battery consumption under control.
For everyday use, the X8 Power should have enough power for:
Social media
Streaming
Multitasking
Photography
Normal gaming
The bigger question is sustained gaming.
A review should focus on frame-rate stability and temperature after 30–60 minutes rather than simply quoting benchmark scores.
The 1.5K AMOLED Display Helps It Feel More Premium
Battery-focused phones have historically made obvious compromises in display quality.
The X8 Power does not appear to follow that formula.
It uses a 6.83-inch 1.5K AMOLED panel with a 120Hz refresh rate, HDR10+ and Dolby Vision support. Gadgets 360 also lists up to 3,500 nits peak brightness and Gorilla Glass Victus 2.
That is a strong specification sheet for multimedia use.
The combination of a large AMOLED panel and a 10,000mAh battery makes the X8 Power particularly interesting for users who watch a lot of video.
The real-world review questions should include outdoor visibility, colour accuracy, low-brightness behaviour and whether 120Hz noticeably affects battery life.
Cameras Look Functional Rather Than Flagship-Focused
The POCO X8 Power uses a 50MP main camera with OIS, an 8MP ultrawide camera and a 32MP selfie camera, according to Gadgets 360.
That is a reasonably versatile setup for a mid-range phone.
But the X8 Power is clearly not being sold primarily as a camera phone.
For a proper review, the most important camera tests would be:
Daylight detail
Dynamic range
Skin tones
Night performance
Ultrawide consistency
Video stabilisation
The presence of OIS on the main camera is encouraging, but image processing will ultimately determine whether the camera feels competitive at ₹35,999.
The Software Commitment Is Strong
The X8 Power ships with HyperOS 3 based on Android 16 and is promised four major OS upgrades and six years of security updates, according to Gadgets 360.
That is important for a device built around longevity.
A phone with a huge battery makes more sense if the software remains supported for several years.
The unanswered question is how well the battery itself will age.
A 10,000mAh battery that loses capacity slowly could make the phone unusually useful over a long ownership period.
Independent long-term testing will be required to know that.
Is 229g Too Heavy?
This may ultimately be the most personal part of the X8 Power.
At roughly 229g, the phone is not absurdly heavy, but it is heavier than many alternatives.
Users who frequently:
may notice the weight quickly.
For someone used to large gaming phones or Ultra-class flagships, however, 229g may not feel particularly unusual.
The key point is that the battery advantage comes with a physical cost.
Who Is the X8 Power Actually For?
The POCO X8 Power makes the most sense for users who prioritise:
Maximum battery life
Long gaming sessions
Frequent travel
Heavy 5G use
Video streaming
Reverse charging
Long software support
It may be especially attractive to users who regularly carry a power bank.
If the X8 Power can replace both a phone and a separate power bank for some users, the added weight becomes easier to justify.
Who Should Probably Skip It?
The phone may make less sense for buyers who prioritise:
Lightweight design
Compact size
Flagship performance
Premium camera hardware
One-handed comfort
Those users may be better served by a lighter mid-range phone with a 5,000mAh to 7,000mAh battery.
The X8 Power is clearly designed around endurance first.
Is ₹35,999 Too Expensive?
The POCO X8 Power starts at ₹35,999, with launch offers bringing the effective price to around ₹32,999. (91mobiles)
At the effective price, the package looks more convincing.
You get:
10,000mAh silicon-carbon battery
100W charging
Snapdragon 6 Gen 5
1.5K 120Hz AMOLED
50MP OIS camera
IP66/IP68/IP69/IP69K protection
Four Android upgrades
Six years of security updates
At the full ₹35,999 price, however, buyers should also compare phones that prioritise stronger processors or better cameras.
The X8 Power’s value depends heavily on whether battery endurance is near the top of your priority list.
The Real Review Verdict Has to Wait
The POCO X8 Power looks extremely interesting on paper.
But this should not be mistaken for a full review.
Until the phone is tested properly, several important questions remain unanswered:
How long does the 10,000mAh battery really last?
Does 100W charging create excessive heat?
How comfortable is 229g after several hours?
Does gaming performance remain stable?
How good is the camera in difficult lighting?
How well is HyperOS optimised?
Those are the details that will decide whether the X8 Power is simply impressive on a specification sheet or genuinely practical.
Final Thoughts
The POCO X8 Power proves that a 10,000mAh battery no longer requires an extremely thick rugged phone.
At around 8.65mm thick, it remains surprisingly conventional in shape, though its 229g weight makes the trade-off obvious. (Gadgets 360)
Its 100W charging, AMOLED display and Snapdragon 6 Gen 5 also mean POCO has not built a phone around battery capacity alone.
The real appeal is straightforward:
For users who are constantly worrying about battery life, the X8 Power could be one of the most practical phones of the year.
For users who already finish most days with plenty of charge remaining, carrying a heavier 10,000mAh phone may solve a problem they do not actually have.
That is why the most important part of reviewing the X8 Power will not be proving that its battery is huge.
It will be determining whether that huge battery makes everyday life meaningfully better.
