When you plug a Xiaomi Redmi into a charger, mysterious icons like lightning, words like "Turbo" or "HyperCharge," and sometimes power numbers appear on the screen. What do they mean? How do you know if fast charging is working on your smartphone? And why can the icons on the same phone differ depending on the power supply?
In this article, weβll take a look at all kinds of fast charging designations on Redmi, from classic models to 2023-2026 flagships, how to distinguish Quick Charge 3.0 from HyperCharge 120W, what the numbers on a power supply (e.g., 5V/3A or 20V/6A) mean, and why charging is sometimes slow despite the lightning on the screen, and weβll also give a table of compatibility between chargers and Redmi models so you can optimally charge your smartphone without risking the battery.
1. The main fast charging technologies Xiaomi: how they differ
Xiaomi uses several fast charging standards, and their designations on the Redmi screen depend on the smartphone model and firmware version.
- β‘ Quick Charge (QC) β standard from Qualcomm, supported by most Redmi on Snapdragon processors: QC 3.0 (18W), QC 4.0 (27W), QC 5.0 (100W+).
- π₯ Turbo Charge β Xiaomi proprietary technology for budget and mid-budget models (for example, Redmi Note 10 Pro supports the same model). 33W).
- β‘β‘ HyperCharge β top charging for flagships (up to) 120W redmi K50 Ultra or 210W experimentally).
- π Pump Charge is a rare technology for ultra-fast charging (for example, the Pump Charge, 200W conceptually).
Itβs important to understand that the designation on the screen depends not only on the support of a smartphone technology, but also on the power supply. For example, if you connect the Redmi Note 12 Pro+ (with 120W support) to the 33W block, the screen will display the βTurboβ icon, not βHyperChargeβ, despite the deviceβs potential.
Itβs also worth noting that Xiaomi sometimes changes the designations depending on the region, for example, in global versions of Redmi can display βFast chargingβ, and in Chinese characters (which translates as βultra-fast chargingβ).
2. Quick charging icons on the screen: decoding with examples
On the lock screen or in the status bar, Xiaomi Redmi displays icons that indicate the type of charging. Here is a full transcript with examples for different models:
| Badge/Inscription | Technology | Max. Power. | Example of model |
|---|---|---|---|
| β‘ (lightning) | Quick Charge 3.0/Turbo Charge (Basic) | 18β27W | Redmi 9, Redmi Note 10 |
| β‘β‘ (two-lightning) | Quick Charge 4+ / Turbo Charge Pro | 30β33W | Redmi Note 11 Pro, Redmi K40 |
| π₯ or "HyperΒ» | HyperCharge | 67β120W | Redmi K50 Gaming, Redmi Note 12 Pro+ |
| Numbers (e.g. "120W") | Maximum power of the power supply unit | Corresponds to the number. | Redmi Note 12 Discovery Edition |
| No badge. | Standard charging (5Wβ10W) | Up to 10W | Any model when connecting to USB-port |
Critical nuance: if the icon is displayed on the screen β‘, But charging is slow (e.g. 1% in 5 minutes), the problem may be in the cable or power supply - they do not support the declared power. 33W non-original USB-A β USB-C can only issue 18W.
π‘
To check the actual charging power, install the AccuBattery app (available on Google Play) that will show the current current and voltage in real time.
3. Labeling on power supplies: how to read labels
Xiaomiβs power supplies contain technical information on the sticker, but not all users can interpret it correctly.
- π Input (Input): for example, 100β240V ~ 50/60Hz 0.8A β These are the parameters of the power grid, they do not affect the charging speed.
- β‘ Output: Power profiles are shown here. Examples: 5V/3A β 15W (standard-charging) 9V/2A β 18W (Quick Charge 3.0) 11V/6A β 66W (HyperCharge) 20V/5A β 100W (Notebooks, but some Redmis support)
- π PPS (Programmable Power Supply: If it is labeled, the unit supports dynamic voltage adjustment (e.g. for Samsung Super Fast Charging, but Xiaomi can also use it).
Example of the block label from Redmi Note 12 Pro+:
INPUT: 100β240V ~ 50/60Hz 1.5A
OUTPUT: 5Vβ3A | 9Vβ3A | 11Vβ6A | 20Vβ3.25A
PPS: 3.3β11V β 3AThis means that the block can issue:
- 15W (5V/3A) is a standard USB.
- 27W (9V/3A) β Quick Charge 4;
- 66W (11V/6A) β HyperCharge;
- 65W (20V/3.25A) β for laptops or high-end smartphones
What if there is no marking on the block?
4.Why there is no fast charging icon on the screen: possible reasons
If your Xiaomi Redmi supports fast charging but doesnβt show up on the screen, the problem may be one of the following:
β οΈ Note: If you use wireless charging, the Redmi Quick Charging icons on the screen are only displayed on models that support Qi 2.0 (e.g. Redmi). K60 In other cases, the indication is standard (no lightning).
- π Unoriginal cable or power supply: even if the unit is 33W, Cheap cable can cut power to the bottom 10W.
- π± Power saving mode is enabled: in Settings β Battery β Power saving mode fast charging is turned off automatically.
- π Firmware problems: after the update MIUI Sometimes you reset your charging settings. Try resetting your settings to Settings. β System system β Resetting settings β Reset the charging settings.
- π Battery wear: If battery capacity falls below 80%, the system may limit current for safety.
To diagnose the problem:
- Connect the original unit and cable.
- Turn off the power saving mode.
- Check the temperature of the smartphone β if it overheats, charging automatically reduces power.
- Install the Throttling Test CPU app to check for heat limits.

5.Fast charging on popular Xiaomi Redmi models: compatibility table
Below is a table with support for fast charging for popular Redmi models (2020-2026). Note that the actual speed depends on the configuration (in some regions, there is a power supply box in the box).
| Model | Max. Power. | Technology | Badge on the screen | Block complete |
|---|---|---|---|---|
| Redmi 10 / 10A | 18W | Quick Charge 3.0 | β‘ | 10W (in some regions) |
| Redmi Note 11 Pro | 67W | Turbo Charge | β‘β‘ or Β«67WΒ» | 67W |
| Redmi K50 Gaming | 120W | HyperCharge | π₯ or Β«120WΒ» | 120W |
| Redmi Note 12 Pro+ | 120W | HyperCharge | "Hyper" or "120W" | 120W (Chinese version) |
| Redmi A2 / A2+ | 10W | Standard. | No badge. | 5W |
Important: In some models (for example, Redmi Note 10S) power supply in the kit does not correspond to the maximum power of the smartphone. So, Note 10S supports 33W, but in the box there is a block on 22.5W. To get full speed, you will have to buy the original Xiaomi unit on 33W.
π‘
If your model supports 67W+, but includes a 33W unit, buying a more powerful RAM will speed up charging by 1.5-2 times (for example, from 1 hour to 30-40 minutes).
6.How to turn on or off fast charging on Xiaomi Redmi
Most Redmi models allow fast charging automatically when a compatible power supply is connected, but some firmware (especially Chinese ones) can manually configure this option.
Go to: Settings β Battery β Battery settings β Fast charging.
In this menu you will see the following options (depending on the model):
- π Enable fast charging - the main switch.
- π Limit charge to 80% β extends battery life, but turns off fast charging after 80%.
- βοΈ Refrigeration when charging β reduces power if the phone overheats.
β οΈ Note: Some models (e.g. Redmi) K60) when activating the Game Turbo mode (Settings) β Special facilities β Game turbos: Fast charging can be temporarily turned off to reduce heating.
If you donβt have a quick charge item on your menu, it means:
- The smartphone does not support technology (for example, Redmi A1).
- A lightweight firmware (e.g. MIUI Lite) is installed;
- The option is hidden in the engineering menu (access to code ##4636##, but you are not recommended to change the settings there).
7. Myths and reality: what is bad for the battery when charging fast
There are many myths surrounding fast charging, and we'll take a look at the most common ones.
- π Myth 1: βFast charging kills the battery in a year.β Reality: Modern Xiaomi smartphones use charging controllers that regulate current and voltage. When properly operated (not to keep charging for days, avoid overheating), the battery will last 3-4 years even when used 120W.
- β‘ Myth 2: "You can only charge your phone with the original unit." Reality: It's not the brand that matters, it's the protocols that matter. For example, Baseus or Anker with Quick Charge 4 support.+ The Redmi Note 11 Pro will charge as fast as the original.
- π₯ Myth 3: "If your phone is warm when charging, it needs to be cooled in the fridge." Reality: A sudden temperature drop is more harmful than heating to 40-45Β°C. It is better to remove the case and put the smartphone on the table (not on a soft surface!).
What really hurts the battery:
- π΅ Charging up to 100% and storage in this state (optimum - 40-80%).
- π‘οΈ Operation at temperatures above 45Β°C or below 0Β°C.
- π Use of damaged cables or blocks with unstable voltage.
π‘
To extend the life of the battery, activate the Adaptive Charging option (Settings β Battery β Battery settings) in the settings, which limits the charge to 80% at night and recharges to 100% by morning.
