Unfortunately, Redmi 15C doesn’t support inductive charging. It is only possible to charge using a traditional charger up to 33 W. Our advanced search will help you find phone models that support inductive charging.
The manufacturer of Redmi 15C has included the option to connect wired headphones via a jack socket in the device's specifications. The user is therefore not limited to using only Bluetooth headphones.

In a word, a low-quality device. Six months of use and the screen burned out. Previously I had a Redmi 13 and it was fine, it did not break until I broke it. I recommend the Redmi 13, but not the 15C.

Very good phone, brilliant battery. The only downside is the lack of a camera, the camera does not handle bright light, it does not handle low light, it is present only because it would be inappropriate not to include one.

Positive opinion

For those complaining about freezing: I had this at the beginning; it probably slowed down for them too. I noticed that the Play Store update from the security level (security status) was responsible. After installing them (there were as many as 4 and the phone had to be reset after each one), it started working very efficiently without delays. A corrective patch was also released, which is worth downloading. I also changed the animations via developer mode from 1.5 to 0.5. This improved the performance; nothing freezes now. Unfortunately, the battery life could be longer. I reported a request for optimization regarding battery stability to them. I will also add that a protective film is applied to the screen at the factory. No LTE band aggregation. Unfortunately, a modem was installed that may drain the battery to some extent.

The worst phone I have ever had in my life – it constantly freezes and heats up. Additionally, when I try to launch something, a black screen appears along with errors stating that the application is not responding. The device was also unable to display the wallpaper that was set; instead, it showed a black screen. I had to wait several seconds for an incoming call to show who was calling, even though the ringtone was playing normally. When taking photos, the phone also froze, which caused the message "Camera is not responding" to be displayed. The only advantages of this phone are a better battery, a large screen, and fast charging; otherwise, it is simply a useless device and I do not recommend it to anyone.

Negative opinion

Patrycja

This phone is no different from its older brother - Redmi 10 5G. A multitude of unnecessary applications, including the entire suite from Google, which no one needs, and most of them cannot be uninstalled or even disabled. The phone has just been taken out of the box, yet it operates with a massive delay. Entering the settings takes about 3-4 seconds. It takes the same amount of time to wake the phone to check the time. After unlocking the screen, even loading a few icons exceeds its capabilities. If anyone claims that this phone works fast, they have probably never encountered a phone that is simply fast. By some strange miracle, a 7-year-old Huawei P30, which is still operational, works more smoothly.

I warn everyone against purchasing this "phone". It is extremely slow, it is the first time I have encountered something like this, basic functions such as calls, messages, or the camera operate with a huge delay or do not work because of these delays; for example, the incoming call window can appear only about 25-20 seconds after the ringing starts (the ringtone is heard but there is no way to answer). After taking a photo, the camera freezes the phone every time for about 30 seconds, it only starts working again after saving. Overall, everything works terribly.

Negative opinion

Aga

I have been using it for two months and I have already ordered a Samsung, Redmi stutters and freezes, someone calls and I cannot answer because I do not see who it is, it is very slow, previously I had a Huawei pro 20 so I have a comparison (excellent phone I recommend it), pages open slowly even though I have a minimum number of applications and few photos.

I find the opinions below somewhat amusing, claiming that the phone is bad, slow, and experiences delays; for me, everything works excellently, including the camera, games, and applications, and the screen is pleasant and bright. The phone is functional and inexpensive; one should buy it and not complain.

Positive opinion

For this price, the phone is very good. I have had it for a month and it performs better than the Galaxy A16, or at least it starts up more quickly. I am surprised that there are negative opinions. I recommend the phone with a clear conscience.
