In January, Realme put a 10,001mAh battery inside the P4 Power at Rs 25,999, a world first nobody touched for nine months. Then Vivo walked in with the S2 FE, launched October 6 at Rs 38,999, and its 10,000mAh cell. One milliamp-hour separates the batteries. Rs 6,000 separates the price tags, by the official numbers. So this Vivo S2 FE vs Realme P4 Power fight is really about what brand, camera and software are worth once the battery stops being the differentiator.
Short version: the Realme is cheaper, faster and charges quicker. The Vivo has to justify itself with selfies and software. Let us see if it can.
The Rs 6,000 question is really a Rs 13,000 story
Here is where it gets interesting. Realme launched the P4 Power at Rs 25,999, then hiked it by Rs 3,000 in August (Gadgets360), taking the base variant to Rs 32,999. Against the S2 FE’s Rs 38,999, the gap is Rs 6,000 today. But during Flipkart’s Big Billion Days sale, the P4 Power dropped to Rs 29,999 (Gadgets360), and at that price the gap is back to Rs 9,000.
Note the RAM column: the Realme gives you 8GB at Rs 32,999, the Vivo 6GB at Rs 38,999. The cheaper phone hands you more memory.
Winner, price: Realme, with a footnote no spec sheet prints. At the hiked price the win is comfortable, not crushing. At the sale price it is a demolition. Time your purchase like a flight booking, because the gap swings by thousands depending on the week. The S2 FE does get 10 percent instant cashback and a 10 percent exchange bonus at its October 20 first sale (The Mobile Indian), which softens the blow on day one.
The battery is a draw. The charging is not.
Capacity is a dead heat, and I mean that literally: 10,001mAh against 10,000mAh, per the brands’ official spec sheets. You will never feel one milliamp-hour. Both brands make heroic endurance claims, Realme with 2.5 days of typical use and over 11 hours of BGMI (Financial Express, DailyKiran), Vivo with 68 hours of calling and 30 hours of video playback (Smartprix). Treat both as marketing, but the direction is right: these are two-to-three-day phones for normal humans.
The asterisk is charging. Realme ships 80W SuperVOOC, good for 0 to 50 percent in about 36 minutes (Financial Express), plus 27W reverse charging, so the phone doubles as a power bank for your earbuds. Vivo ships 44W into a 10,000mAh cell, an overnight affair. Our Vivo S2 FE review flagged this compromise, and it stings here because the rival refills in half the time.
The Realme also has bypass charging, routing power straight to the board while you game so the battery does not cook. Vivo’s own S2 has it. The FE, per the spec sheets, does not.
Winner, battery: Realme. The cells tie. The charging does not.
Chips and screens: a tier apart
The Realme’s 6.8-inch 1.5K curved AMOLED runs at 144Hz with a claimed peak brightness up to 6,500 nits (Hindustan Times). The Vivo’s 6.83-inch 1.5K AMOLED runs at 120Hz. Both panels survive harsh Indian sunlight. But if you game, the Realme’s higher refresh rate is a real, felt advantage, and it pairs with stronger silicon.
The Dimensity 7400 Ultra in the Realme is simply a tier above the Dimensity 7300e in the Vivo. We covered what this performance tier feels like in our Realme P4 Pro vs Vivo V60e comparison: smooth heavy gaming, cool sustained loads, headroom for years. MySmartPrice’s expert review of the P4 Power scores it 8.3 out of 10 overall. The 7300e is a dependable daily-use chip with a 3,800 sq mm vapour chamber keeping it honest, and it will handle BGMI at moderate settings. Dependable is not the same as fast.
Winner, display: Realme. Winner, performance: Realme.
Cameras: Vivo owns selfies, Realme owns everything else
Here is where Vivo finally lands a punch. The S2 FE carries a 50MP Sony IMX852 main sensor and, more importantly, a 32MP front camera with the Aura Light ring that flatters night portraits instead of blasting them with flash. If your camera roll is people, this is the better camera phone, full stop.
The Realme counters with a 50MP Sony IMX882 main camera with 2-axis OIS, an 8MP ultra-wide, and a 16MP front camera (opchatgpt, Cashify). The ultra-wide is the meaningful difference: an actual second camera, not a 2MP bokeh decoration like the Vivo’s secondary sensor. For landscapes and group shots, the Realme is the more versatile shooter.
Winner, camera: split, honestly. Vivo for selfie and portrait people. Realme for everyone else.
Built for abuse: both survive, Vivo survives more
The Realme carries IP66, IP68 and IP69 ratings (Cashify), which is already more than most phones at this price offer. The Vivo carries IP68 plus IP69, adds MIL-STD-810H shock resistance, and stereo speakers on top. One monsoon will not kill either phone. A clumsy year might.
Both are impressively light for five-figure batteries: 219g and 9.08mm for the Realme, 224g and 8.59mm for the Vivo, per the official spec sheets. The Realme’s polycarbonate back feels less premium than glass, and it has a single down-firing speaker, a real con for a media-first phone (Cashify).
Software is a taste call. OriginOS 6 on Android 16 for the Vivo, Realme UI 7.0 on Android 16 for the Realme. Realme makes a genuine long-term pitch here: a four-year battery health guarantee, promising to replace the battery if its health falls below 80 percent (DailyKiran). For a phone whose entire personality is the battery, that is the single most reassuring sentence any brand has attached to a 10,000mAh phone this year, and Vivo has no answer for it.
Winner, durability: Vivo, on the MIL-STD rating. Winner, peace of mind: Realme, on the battery guarantee.
Vivo S2 FE vs Realme P4 Power: the verdict
Score it straight. Price, battery charging, display and performance go to Realme. Durability goes to Vivo. Cameras split by buyer type. Battery peace of mind, oddly, goes to Realme too.
The overall winner is the Realme P4 Power, and at street prices I do not think it is close. It costs Rs 6,000 less, charges in nearly half the time, runs a faster chip with a smoother screen, and gives you more RAM at the base variant. Buy it during a sale, when the gap stretches toward Rs 9,000, and the argument becomes mathematical.
Buy the Realme P4 Power if you want the most phone your money can buy, full stop. Buy the Vivo S2 FE only if you are specifically a Vivo person: you prefer OriginOS, you shoot a lot of selfies and night portraits, you want the MIL-STD durability rating, or the October 20 launch offers with the 10 percent cashback tip the maths for you.
Realme’s own August hike narrowed its value story from a landslide to a comfortable win. And Vivo charges flagship-adjacent money for a mid-range chip and 44W charging while Realme sells the faster phone for six thousand less. The battery war is over. Realme won it in January. Vivo showed up nine months later asking a premium for the sequel.
