Not across the board. Compared with the global REDMI 15, the global REDMI 17 5G offers a larger listed battery and faster charging, while the REDMI 15 has a sharper display with a higher refresh-rate ceiling. The right choice depends on which trade-off matters more—and on which regional model you are actually buying.
First, identify which REDMI 17 you mean
Xiaomi lists two distinct phones: REDMI 17 5G and REDMI 17, a separately specified non-5G model. Their processors differ: Xiaomi lists Snapdragon 4 Gen 5 for the global 17 5G and MediaTek Helio G91-Ultra for the non-5G REDMI 17. The comparison below uses the global REDMI 17 5G and global REDMI 15, so it should not be applied automatically to every market or to the non-5G phone.

Where the REDMI 15 has the advantage: its display
Both global models list a 6.9-inch screen, but the REDMI 15 specifies 2340 × 1080 resolution and up to 144Hz, compared with 1600 × 720 and up to 120Hz on the REDMI 17 5G. That gives the REDMI 15 the stronger display specification on paper: its higher resolution means more pixels, and its refresh-rate ceiling is higher. A refresh rate is a maximum specification, not a guarantee that every app or use case will run at that rate.
Where the REDMI 17 5G has the advantage: battery capacity and charging
On Xiaomi’s global specifications, the REDMI 17 5G has a 7500mAh typical battery and supports 45W charging; the REDMI 15 lists 7000mAh and 33W. That is a 500mAh capacity difference and a higher supported charging rate for the 17 5G. These figures do not establish how long either phone lasts in everyday use or how quickly it charges in every situation; no independent battery or charging comparison is available here.

Package contents depend on the market. Xiaomi’s global REDMI 17 5G specifications say, “No power adapter is included in the box.” Xiaomi India’s REDMI 17 5G product page says a charger is included. Check the exact local listing before assuming a charger comes with the phone.

Performance, cameras and everyday extras: what the specifications do—and do not—show
Processor and memory
The two global listings name different processors, and the 17 5G has a newer-sounding model name and smaller listed manufacturing process. Those details alone do not prove which phone feels faster in real use: no independent benchmark or hands-on performance comparison is established here. The listed RAM options also differ. The REDMI 15 starts at 6GB, while the REDMI 17 5G has a 4GB option, so compare the memory configuration—not just the phone name—when checking a specific listing.

Cameras
Both global pages list a 50MP main rear camera and an 8MP front camera. Matching headline resolutions do not establish equal image quality, and they are not evidence that one phone takes better photos. No independent camera comparison is available here.
Storage, water resistance and software
Both pages list 128GB and 256GB storage options, microSD expansion up to 2TB, and an IP64 rating. The microSD slot is hybrid, so using a memory card may require choosing between the card and a second SIM; confirm the tray arrangement for the regional model. IP64 is a dust- and splash-resistance rating under controlled conditions, not a claim that either phone is waterproof.

Xiaomi’s global pages name HyperOS 3 for the REDMI 17 5G and HyperOS 2 for the REDMI 15. Software versions, features and update availability can depend on the exact model and region. Xiaomi India states four years of OS updates and six years of security updates for its REDMI 17 5G page; treat that as a market-specific commitment, not a promise for every REDMI 17 5G worldwide.
Regional differences can change the buying decision
The India REDMI 17 5G page lists a 7900mAh typical battery rather than the 7500mAh on Xiaomi’s global 17 5G specifications, and says a charger is included. It also names HyperOS 3 based on Android 16 and gives the India-specific update commitment described above. These are regional claims; do not combine them with global specifications as though they describe one universal configuration.

Xiaomi’s global REDMI 17 5G specs and REDMI 15 specs both flag regional variation.
Quick Recap
Which one should you choose?
- Choose the REDMI 15 if display sharpness and the higher listed refresh-rate ceiling matter more to you than the 17 5G’s battery and charging specifications.
- Consider the global REDMI 17 5G if you value its listed 7500mAh battery, 45W charging support and 5G, and its HD+ display is acceptable to you.
- Compare local prices and exact configurations before deciding. A current price comparison and independent performance, battery-life and camera tests are not established here, so the specifications alone cannot show which is the better overall value or faster phone.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
