Redmi 15

Technical specifications

Redmi 15 (4G) 8/256 GB.
model: 25062RN2DY
SN:67677/65U900741
Barcode: 6932554445102
I purchased it officially in a hypermarket last week. Color: Midnight Black. Factory sealed box. Inside, a USB A - USB C cable. A black back cover case and a card tray tool. Manual in Polish, but not much is described there. A factory applied film on the screen.

The card tray contains two slots:
- SIM1 slot
- hybrid SIM2/SD slot
Test code:
*#*#6484#*#*
Currently, it has Android 15 and HyperOS 2. Security updates 1.10.2025. Developer Options after repeatedly clicking on the text "OS version" (Settings/About phone/OS version). After the purchase, there was some work with removing unnecessary applications. I tested everything, especially the reverse charging.

I would add some notes to the specifications, because perhaps models from other locations have different specifications:
- the main camera is probably 50 Mpx. I have no way to check, but manufacturer pages and websites state so.
- there is no Macro mode, as I checked all camera options
- the proximity sensor is probably only virtual, because after entering the tests with the code *#*#6484#*#*, I could not activate this sensor.
- there is a flash with four modes to choose from: off/on/Auto/Flashlight
- digital zoom only up to 2x
- there are two protruding lenses, and the third one at the bottom is not protruding. This is probably some kind of sensor, because no typical lens opening is visible.
- reverse charging starts immediately after connection and there is no need to turn on OTG or any other setting, nor to wake the screen. The manufacturer declares 18 W power. I did not measure it, but it charges.
- the sound in wired headphones via an inexpensive USB"C"-jack 3,5 adapter is good. Clear and stereo. I note that I am not an expert on sound quality.
- there is an accelerometer
- there is probably no gyroscope, because the test application does not include it
- the "find phone" function works even on very slow internet (32 kbps) and does not charge any fees, although the application warns about paid SMS. Everyone must check this individually.
- I have not yet tested the 2 TB SD card.
For 650 PLN, for my specific needs, it is OK.
POCO M7 4G is identical to Redmi 15 4G. Perhaps they only differ in some GSM bands.
I can only thank you for this comment and apologize for the inaccuracies and deficiencies in the specification. It was prepared based on very early data, and later, through my fault, it was not verified during the official premiere. Yes, 50 Mpx camera + sensor, probably 0,08 Mpx, no third camera and no macro. There is a memory card, a hybrid slot and 18 W reverse charging. Indeed, there is no proximity sensor (emulation) and no gyroscope. I will also add that NFC is available in official sales in Poland, but be careful when buying abroad or second hand, because in other versions it may be missing. Once again, thank you very much and best regards. (jf)

Today I received the HyperOS 3 update along with Android 16, and it downloaded as much as 4.9 GB.

It changed to an unattractive custom theme.
There is no way to set the standard theme back. This option has completely disappeared.

It is possible that this only happened to me, because I played around a bit with inserting various widgets, and in the end, none of the available ones suited me.

So I did a factory reset and I hope it will be fine now.
I do not like the AppMall, GetApps, and AppVault applications, so I restricted their operation as well as the notifications from these applications.

Overall, it seems to me that the latest HyperOS 3.0.6.0 has improved the interface appearance slightly. For now, the smartphone is working well.
It was therefore worth performing a factory reset, although it took some time to reinstall the applications and re-configure the settings.

This is a quite large "massive phone", so it is worth taking into account, because it is not a defect but simply a characteristic. There is only one speaker for sound (mono) and it has poor quality. The number of advertisements and suggestions is irritating, as is typical for Xaomi, and you have to spend a lot of time disabling them. The battery performs its function, which is a fairly big advantage. The speed itself is, in my opinion, acceptable; it does not slow down significantly, it does not happen to it.

Update 1.1 GB.
Current status:
HyperOS 3.0.302.0.WBOMIXM.C07
Android 16
Security 1.05.2026
Google Play system app: June 1 2026.

My memory was expanded by 4 GB, but I turned it off, which resulted in a restart.
I turned off GetApps.

As of now, meaning for months, I have not been bothered by any advertisements. However, I previously had to perform certain actions during the initial configuration after purchase.

I bought this phone in October. A few months of use and I already dislike it. In literally every camera mode, if I cover two cameras, meaning the second and third from the top, my hand is still not visible, so only the first one is real. It is supposed to have 144hz, but the phone stutters. A solid 5/10.

February 1, 2026 patch 55 MB. HyperOS 3.0.10.0 Everything seems to be working. Unnecessary applications Agoda and Lazada were added at the same time. Both are invisible in Google Play. I went into Settings/Applications and uninstalled those two applications there.

December update, and HyperOS with a higher additional version number 3.0.9. A 1.6 GB file was downloaded.
