What is Xiaomi Redmi VXN4304GL and why it is important to charge it correctly
Xiaomi Redmi VXN4304GL is a portable device with built-in battery that combines Smart TV features and battery life. Unlike classic TVs that require constant connection to the outlet, this model has a 10,000 mAh battery that allows you to use it when traveling, in the country or during power outages. However, improper charging can lead to a shorter battery life or even failure.
Many users mistakenly believe that a battery TV charges the same as a smartphone or tablet. In fact, the Redmi VXN4304GL has unique features: it supports fast 65W charging, but is sensitive to overheating and unstable voltage. In this article, we will discuss how long it takes to fully charge, how to avoid typical errors and what to do if the device does not charge.
It’s important to understand that charging time depends not only on battery capacity, but also on battery status, charger used, ambient temperature and even firmware version. If you just bought a Xiaomi Redmi VXN4304GL or noticed that the battery is running out too quickly, this guide will help you understand the nuances.
Official data: how much time is charged Xiaomi Redmi VXN4304GL
According to Xiaomi’s technical documentation, the Redmi VXN4304GL fully discharged TV can charge up to 100% in 2.5–3 hours using the original charger (65W).
- 🔌 With the original adapter 65W: 2.5–3 hours (0% to 100%).
- 🔋 With an adapter. 30W–45W: 4-5 hours (charging is slower, but safe).
- ⚡ When charging from USB-Laptop port: 6-8 hours (not recommended for permanent use).
- 🌡️ Lower temperature +10°C or higher +35°C: Time increases by 20-30%.
Now, interestingly, the first 80 percent of the battery's capacity is gained in about 1.5 hours, and the remaining 20 percent can take as long, because the last step of charging is down-current to protect the battery from overload.
| Type of charger | Power | Charging time (0–100%) | Recommendations |
|---|---|---|---|
| The original adapter Xiaomi | 65W | 2.5–3 hours | The best option |
| Third-party adapter (Quick Charge) | 45W | 3.5-4) hours | It is acceptable, but check the compatibility. |
| USB-laptop-port | 5W–10W | 6-8 hours | Only as a last resort. |
| Power Bank (20,000 mAh) | 18W–22W | 5-6 hours | Suitable for travel |
Critical information: If the TV does not charge for more than 8 hours using a 65W adapter, this may indicate a malfunction of the battery or power controller, in which case a diagnosis is required at the service center.
Step-by-step: how to charge Xiaomi Redmi VXN4304GL
To extend the battery life and avoid charging problems, follow this instruction:
- Use the original cable and adapter. The cable must support a current of at least 3A, otherwise charging will be slow or interrupted.
- Connect the TV to a grounded outlet. Avoid extension cords and tees, which can cause interference.
- Turn on the TV (not necessarily, but recommended) when it's off, it's slower to charge because of firmware limitations.
- Wait until you're fully charged. Don't interrupt the process unless the battery has gained at least 80%.
- Turn off the power when the indicator shows 100%.
If the TV is completely discharged (does not turn on), wait 10-15 minutes after charging is connected - sometimes it takes time to "wake up" the power controller.
Check the integrity of the cable and adapter|Use a grounded socket|Make sure the temperature in the room +15..+30°C|Do not cover the TV while charging.|Turn off energy-intensive functions (for example, maximum brightness)-->
Tip: If you charge your TV for the first time after you buy it, let it completely discharge and charge 2-3 times, which will help calibrate the battery controller to more accurately display the charge level.
Typical charging errors and how to avoid them
Many users make the same mistakes that lead to rapid battery wear or unstable TV performance, and the most common ones are:
- 🔥 Overheating of the device. Charging at a higher temperature +35°C or in direct sunlight accelerates battery degradation: +15..+30°C.
- ⚡ Using uncertified chargers: Cheap adapters can produce unstable voltages, causing the power controller to fail.
- 🔋 Keeping the battery charge 100% constant, and if the TV is on charge for a long time after reaching 100%, it reduces battery life.
- 📉 Deep discharge. If the battery runs down to 0% and stays in this state for a long time, it can lose some of the capacity. Try to charge the TV at 10-20% charge.
⚠️ Warning: If the TV suddenly turns off at a charge level of 30-50%, this is a sign of a malfunction of the battery.
Another common problem is slow charging, and if the TV charges for more than 5 hours with the original adapter, check:
- Integrity of the cable (bending, damage to insulation).
- Clean USB-C connector on your TV (dust and dirt can impair contact).
- Power saving settings in the TV menu (sometimes limit the charging current).
What if the TV doesn’t charge at all?
How to extend the battery life of Xiaomi Redmi VXN4304GL
The Redmi VXN4304GL battery is designed for 500-800 charge cycles (depending on operating conditions). To maximize its capacity, follow these recommendations:
- 🔄 Avoid full discharges. The optimal charge range is 20-80%. Regular discharges to 0% reduce the life of the battery.
- 🌡️ Control the temperature. Don't leave the TV on charge in a hot room or in the sun.
- ⚡ Use only certified accessories, cheap cables and adapters can damage the power controller.
- 📵 Disable unnecessary features. Wi-Fi, Bluetooth and high screen brightness increase battery consumption.
- 🔋 Store with a charge of 40-60%. If the TV is not in use for a long time, leave it with half the charge.
