The OPPO K13 is the better fit if you want an OLED screen and faster rated wired charging; the Moto G57 Power is the better fit if you want a slightly larger LCD, an ultrawide rear camera or a 3.5mm headphone jack. Both are 5G phones with 7000mAh batteries. Price listings put them about ₹1,000 apart, but check the same storage variant and your live checkout price before deciding.

Manufacturer pages are the best source for each brand’s own product claims, while comparison listings may reflect a particular market or variant. In particular, confirm the regional G57 Power model before relying on memory, SIM, NFC or charging details. Motorola lists different memory and charging configurations across its US and UK pages.
Display: OLED versus a slightly larger LCD
The K13’s 6.67-inch OLED panel is the key choice if contrast and OLED display technology matter most to you. The Moto G57 Power has a marginally larger 6.72-inch LCD, and both are listed at 120Hz. The available specifications do not establish a direct brightness or color-accuracy comparison, so choose by panel preference rather than assuming one is superior in every viewing condition.
Performance and software
OPPO lists the Snapdragon 6 Gen 4 in the K13; Motorola lists the Snapdragon 6s Gen 4 in the G57 Power. The similar names do not establish which phone performs better in everyday use, and the supplied specifications do not provide a controlled head-to-head performance test.

For another reference point, 91mobiles reported Geekbench multi-core scores of 3,088 for the K13 and 2,931 for the G57 Power, accessed October 5, 2026. These are that publisher’s reported results, not a test conducted for this article, and a benchmark score alone does not predict every app or workload.
The comparison listing shows Android 15 with ColorOS 15 for the K13; Motorola’s support page lists Android 16 for the G57 Power. These are the software versions shown by those sources, not a guarantee of the version installed on every regional unit or of future update support.
Battery and charging
Both phones are specified with 7000mAh batteries, so nominal battery capacity does not distinguish them. OPPO additionally states a 6820mAh rated capacity for the K13. Motorola’s “up to 60 hours” battery-life figure is a manufacturer claim, not a promise of that runtime in ordinary use.

The K13 lists 80W SUPERVOOC charging. OPPO says its lab test charged the phone to 62% in about 30 minutes from 1%, using the included adapter with the display off under controlled temperature conditions; actual charging depends on conditions. Motorola’s charging rating differs between its market pages—33W on the US page and 30W on the UK page—so check the India-market G57 Power SKU rather than assuming either rating applies.
91mobiles reported PCMark battery-test results of 17 hours 2 minutes for the K13 and 15 hours 18 minutes for the G57 Power, accessed October 5, 2026. Those are results under that publisher’s test method, not a forecast for every user’s screen brightness, network conditions or workload.
Cameras and audio
The G57 Power has a 50MP Sony LYTIA 600 main camera and an 8MP ultrawide camera, giving it a clearly specified ultrawide option. The K13 is listed with a 50MP main camera and a 2MP secondary camera; the comparison listing does not identify that secondary sensor as an ultrawide. For selfies, the comparison listing gives the K13 a 16MP front camera, while Motorola support lists 8MP for the G57 Power.

If you use wired headphones, the G57 Power’s 3.5mm headset jack is a practical advantage. The K13 is listed without one.
India price difference
Online prices are snapshots, not guaranteed current offers. The listings available in the comparison sources show:
| Phone | 91mobiles listing | Smartprix listing |
|---|---|---|
| OPPO K13 | ₹21,999 on Flipkart | ₹21,999 |
| Moto G57 Power | ₹20,990 on Amazon | ₹20,999 |
| Approximate gap in those snapshots | ₹1,009, with the Moto lower | ₹1,000, with the Moto lower |
Smartprix says its page was updated September 24, 2026. These figures indicate a roughly ₹1,000 gap in those snapshots, not a fixed current price. Discounts, stock and storage variants can change the checkout total; compare the same storage configuration on live India listings.
Which phone should you buy?
Choose OPPO K13 if
- You prefer an OLED display over an LCD.
- You value its listed 80W SUPERVOOC wired charging.
Choose Moto G57 Power if
- You want the slightly larger screen, an 8MP ultrawide rear camera or a 3.5mm headphone jack.
- You find it cheaper for the same storage variant at checkout.
Do not choose on battery capacity alone: both are specified at 7000mAh. Nor should the processor names by themselves settle the decision. Compare the live India SKU and price, then prioritize the features you will use.
