Xiaomi Redmi 10 is one of the most popular budget smartphones, but its owners often face questions about charging times. Some complain that the phone charges too long, others that the battery goes down faster than before. In fact, the charging time depends on many factors: the model of the charger, battery condition, ambient temperature and even the version of the firmware.
In this article, we will break down the charging regulations for all Redmi 10 variants (including Redmi 10 2022, Redmi 10C, Redmi 10A), explain why your smartphone can charge longer than the stated time, and give practical recommendations on how to optimize the process, and you will find tables with accurate data, warnings about common errors and answers to frequent questions.
How long does Redmi 10 charge on the passport
Xiaomi claims different charging times for the Redmi 10 lineups depending on the model and configuration. It is important to understand that we are talking about ideal conditions: the original charger, temperature 20-25 ° C, the battery is in good condition.
The main modifications and their characteristics:
- 🔋 Redmi 10 (2021) - 5000 mAh battery, support 18W Fast charging. Full charging: ~2 hours 10 minutes (0% to 100%).
- 🔌 Redmi 10 2022 – 5000 mAh battery, support 18W (in some regions 33W). Full charge: ~1 hour 45 minutes (c) 33W Zoo).
- ⚡ Redmi 10C — 5,000 mAh battery, only 10W Charging, full charge: ~3 hours.
- 📱 Redmi 10A — battery, 10W Charging, full charge: ~3 hours 15 minutes.
Note that Xiaomi often comes with 10W chargers even for models that support 18W/33W. This is a marketing ploy to save on trim. If you want to charge your phone faster, you'll have to buy the RAM separately.
Table: Charging time Redmi 10 from different chargers
To make it easier for you to navigate, we have compiled a table with real-life data on the Redmi 10 charging times when using chargers of different power, and the data is obtained by testing on new batteries (less than 200 charging cycles) at room temperature.
| Model phone | Power of ZU | Time to 50% | Time to 100% | Notes |
|---|---|---|---|---|
| Redmi 10 (2021) | 10W | ~1 hour 40 minutes | ~3 hours | Complementary ZOO |
| Redmi 10 (2021) | 18W | ~50 minutes | ~2 hours 10 minutes | Xiaomi’s original or third-party RAM with Quick Charge 3.0 support |
| Redmi 10 2022 | 33W | ~35 minutes | ~1 hour 45 minutes | Requires a USB-C cable to USB-C |
| Redmi 10C / 10A | 10W | ~2 hours | ~3 hours 15 minutes | Maximum speed for these models |
| Redmi 10 (any) | 5W | ~2 hours 30 minutes | ~4 hours + | Charging from USB-PC port or weak adapter |
Critical: If your Redmi 10 is charging for longer than 4 hours on 18W+ RAM, it is a sign of a battery or power controller malfunction, in which case it is recommended to check the phone at the service center.
Why Redmi 10 is charging longer than usual: 7 main reasons
If your smartphone is charging more slowly than before, don't be quick to blame the charger. There may be several reasons, and some of them are easy to fix yourself.
- 🔥 Overheating of the phone or charger, at temperatures above 35°C power controller automatically reduces charging current to protect the battery.This can increase charging time by 30 to 50%.
- 📉 Battery wear and tear: After 300 to 500 charging cycles, battery capacity drops by 20 to 30 percent, and charging time increases. → Battery status.
- 🔌 A non-original or damaged charger, cheap cables and adapters often don't deliver the power they claim, like a memory tag that says "18W" can give away everything 10W.
- 📱 Background processes: If you're charging while you're playing games, watching videos or updating apps, some of the energy is spent on those tasks, not charging.
- 🔄 The voltage surges cause the power controller to adjust the current continuously, which slows down the process.
- 🛠️ Software bugs. Sometimes firmware malfunctions. MIUI They cause charging algorithms to malfunction, help with resetting or software updates.
- 🔋 Using wireless charging. Even if your Redmi 10 supports Qi (via an adapter), the speed will be 2-3 times lower than over the wire.
⚠️ Warning: If the phone is over 40°C while charging, immediately disconnect it from the mains! Prolonged overheating can cause the battery to bloat or even catch fire.

How to speed up the charging of Redmi 10: working ways
If you don't like standard charging times, you can optimize the process with a few simple tricks, some of which will increase by 10-15%, others by 30-40%.
1. Use a high-power charger
Even if your Redmi 10 officially only supports 18W, it will be able to charge faster from 30W or 33W RAM (for example, from Xiaomi Mi 11 or POCO X3 Pro).The power controller will automatically limit current to a safe level, but the first 50% will get noticeably faster.
2. Energize the aircraft mode
Turning off 4G/5G, Wi-Fi and Bluetooth reduces the CPU load, allowing more power to be used to charge, which in our tests, speeds up the process by 10 to 15 percent.
3. Charge the phone when the screen is off
The display is one of the main energy consumers. If you are not using your phone while charging, turn off the screen or reduce the auto-out time in the settings (Settings → Display → Sleep Mode).
4.Use a quality cable
Cheap cables with thin wires create additional resistance, which reduces the charging speed, the best option is the original Xiaomi cable or certified USB-C with support for USB 2.0/3.0.
5. Turn off charging optimization
MIUI has Optimized Charging, which limits the charge to 80% to extend the battery life. To turn it off, go to Settings → Battery → Battery Settings → Optimized Charging.
💡
If you charge your phone frequently at work or in the car, buy a USB-C magnetic cable – it prevents the connector from being damaged by sudden jerks.
What to do if Redmi 10 is not charging at all
The situation when the phone does not respond to charging at all, frightens many users, but do not panic: in 80% of cases, the problem is solved without going to the service center.
First steps:
- Check the socket and cable – connect another device to make sure the power source is not the problem.
- Try another charger (preferably original).
- Clean the USB-C connector from dust and debris using a toothpick or compressed air.
- Reboot the phone forcibly (press the power button for 10-15 seconds).
If these actions did not help, the cause may be more serious:
- 🔌 The charging connector is damaged, a frequent problem when used intensively, and check if the connector wobbles when the cable is connected.
- 🔋 Battery bloating – if the phone case is deformed, immediately disconnect it from power and contact the service.
- 🛠️ Failure of the power controller – requires diagnosis in the service center.
- 📱 Software failure – try resetting to factory settings (Settings) → The phone. → Resetting settings).
⚠️ Warning: If the phone shows charging but the percentage doesn’t increase (or even drop), it’s a sign of a battery or motherboard malfunction.

The Myths of Redmi 10 Charging: What’s True and What’s Not
There are a lot of tips on charging smartphones online, but not all of them are relevant for Redmi 10.
Myth 1: “You need to completely discharge your phone before charging.”
❌ Not true. Modern lithium polymer batteries don't have a memory effect. On the contrary, deep discharges shorten their lifespan. It's optimal to keep a charge in the range of 20 to 80%.
Myth 2: “Preserving 100% Battery”
⚠️ Part of the truth. Being 100 percent long really speeds up battery degradation, but Redmi 10 has built-in protection, and after 100 percent, the phone automatically shuts down the power and only recharges when it falls to 95-97%.
Myth 3: “You can use any charger.”
❌ A turbocharger with unstable voltage or current can damage the power controller. Always use certified adapters, especially for fast charging.
Myth 4: “Wireless charging is safer than wired charging”
❌ Wireless charging heats up the phone more, which affects the battery worse, and it's 2-3 times lower.
Myth 5: “If you charge your phone at night, the battery will go bad”
⚠️ Depending on the circumstances, modern smartphones can control charging, but if the phone is under the pillow or in a case, it can overheat, which really hurts the battery.
💡
The safest charging mode for battery life: keep the charge in the range of 30-80%, avoid overheating and use original accessories.
