You just unpacked your new Xiaomi Redmi Note 10 and want to keep its battery lasting as long as possible? First charging your smartphone isn’t just about plugging in. How you charge your device in the first hours determines its future battery life and battery life. In this article, we’ll break down the myths and facts about first charging, explain why old tips (like “discharge to 0%”) are no longer relevant for today’s lithium polymer batteries, and give you a step-by-step guide based on recommendations and Xiaomi experts on lithium-ion batteries.
Many users mistakenly think that the new battery requires "training" -- a full discharge-charging cycle. This was true for nickel-metal hydride batteries 20 years ago, but the Redmi Note 10 has a modern Li-Po battery that doesn't need such manipulations. Moreover, deep discharge can damage such a battery. We'll tell you how to properly prepare the smartphone for the first charge, which adapter to use, and what to do (and what not to do!) in the process.
Important: this instruction takes into account the features of the Redmi Note 10 (models M2101K6G, M2101K6I, M2101K6P), including its battery capacity of 5000 mAh and support for fast charging Quick Charge 3.0. If you have another modification (for example, Redmi Note 10 Pro or Note 10S), some parameters may differ.
Myths about the first charge: what actually harms the battery
Before we get to the instructions, let’s deal with common misconceptions that can shorten the battery life of your Redmi Note 10:
- 🔋 Myth 1: "You need to completely discharge the phone before you charge it. Reality: For lithium polymer batteries, deep discharge (below) 3%) harmful - this leads to irreversible degradation of the capacity. Xiaomi recommends starting charging when 20-30%.
- ⚡ Myth 2: "The first 3 charges should be 12 hours." Reality: Modern charging controllers (including: MTK Pump Express in Redmi Note 10 automatically shuts off power when it reaches 100%. Recharging is impossible, and a long connection to the network only heats the battery.
- 📱 Myth 3: "You can't use your phone while you first charge." Reality: Easy use (messaging, calling) doesn't hurt, but games or video editing raise the temperature of the battery, which speeds up the wear and tear. Optimum: minimal load.
- 🔌 Myth 4: "You can only charge with the original adapter." Reality: It's important to keep power (at least lower than that). 18W for fast charging) and use certified cables. adapter from Redmi Note 9 (also 18W) It's okay, but it's 300-dollar. ₽ — no.
The most dangerous myth is ignoring the temperature regime: Charging the Redmi Note 10 at temperatures below 0 °C or above 40 °C can lead to irreversible damage to the battery after 2-3 such cycles. In the next section, we will explain how to avoid overheating.
Preparation for the first charge: what to do before connecting to the outlet
Before you plug the plug into the socket, follow these steps, which will help avoid typical errors and prolong the life of the battery:
Update your firmware to the latest version (path: Settings → About Phone → System Update)
Make sure the temperature of the phone is in the range of 10–35°C (check in Settings → Battery)
Turn off background processes (especially games and social networks) in Settings → Applications → Auto Run
Use the original USB-C cable (or certified with the USB-IF logo)
Check that the charger connector on the phone is clean (dust can cause overheating)-->
Why is it important to upgrade your firmware? Newer versions of MIUI have optimized battery management algorithms. For example, MIUI 14 has added Adaptive Charging mode, which automatically limits your charge to 80 percent at night if you plug your phone in before bedtime, which reduces battery wear by 20 to 30 percent per year.
Temperature is critical. If the Redmi Note 10 was cold (for example, it was brought in in the winter from delivery), let it heat up to room temperature for at least 1 hour. Charging a cold battery leads to the formation of dendrites - microscopic metal "needles" that can close the battery cells.
⚠️ Note: If you bought Redmi Note 10 "hands-on" and do not know the history of its operation, before the first charge check the battery status in the engineering menu. To do this, enter the phone application code # #4636##, go to the Battery information section and compare the value of health with the table below.
| The importance of health | Battery status | Recommendations |
|---|---|---|
| 100% | Perfect. | You can charge without restrictions |
| 90–99% | Normal wear and tear | Follow the instructions, but avoid fast charging. |
| 80–89% | Strong wear and tear | Limit your charge to 80%, plan to replace your battery |
| below 80% | Critical | Do not use fast charging, contact the service |
Step-by-step: how to charge the new Redmi Note 10 correctly
Now, the main thing is the charging process itself, and follow this instruction to maximize battery capacity.
- Step 1. Connect the original adapter. Use the power supply from the kit (18W, 9V/2A). If it is lost, take an adapter with similar parameters (for example, from the Redmi Note 9 Pro or POCO X3). Do not use charging from old phones (5W) - this will increase charging and heating time.
- Step 2. Put the phone in the socket. Connect the cable to the smartphone first, then plug the plug into the socket, which reduces the risk of a power surge.
- Step 3: Wait for 20 to 30 percent of the charge, and if the phone is completely discharged, let it stand on a charge for 10 to 15 minutes before it turns on, and that protects the power controller from overloading.
- Step 4: Charge to 100% without interruption. Don't disconnect your phone from the network until the indicator shows 100%. For the Redmi Note 10 with fast charging, it will take about 1 hour and 40 minutes.
- Step 5: Disconnect from the grid immediately after full charge.Despite recharge protection, long-term network connection (more than 2 hours after 100%) increases the battery temperature.
What to do after the first charge? We recommend that you run 1-2 full cycles (20 to 100%) in the first days of use, which will help calibrate the battery controller. However, do not discharge the phone before automatically turning off - this harms lithium polymer cells.
💡
If you plan to use Redmi Note 10 intensively (games, video shooting), activate Performance mode in Settings → Battery → Battery modes only after full charge. Enabling this mode at low charge speeds up battery wear.
What to do with the first (and subsequent) charge
Even if you do the first charge correctly, some actions can negate its benefits. Here are the most dangerous mistakes of Redmi Note 10 owners:
- 🔥 Use your phone in your case while charging. Cases (especially silicone) degrade heat sink. Battery temperature can rise to 45.°C, which reduces its resource by 10-15% per year.
- ⚡ Connect to smart sockets with a timer, and if the socket turns off power by 80%, the battery controller may get lost, and the phone will show the wrong level of charge.
- 📵 Charge from USB-Computer port or power bank (2.5W–5W) Not enough to properly calibrate the battery 5000 mAh. Exception: power bank with Quick Charge 3.0 support.
- 🛌 Leave it to charge overnight, even with adaptive charging, long-term grid connection increases battery temperature, optimal: charge up to 80% before bedtime and turn off.
⚠️ Warning: If the Redmi Note 10 gets too hot during charging (the body is hot, not warm), disconnect it immediately from the grid.°C can cause the battery to bloat, in which case do not turn the phone on until it has cooled down completely (at least 30 minutes).
Pay special attention to the cable, and if you have a damaged insulation or a bent USB-C connector, you can short-circuit the cable.
- 🔍 Cracks or scuffs near the plug;
- 🔌 Luft when connecting to the phone;
- 📉 Falling charging speed (e.g. with 18W before 10W).
How to extend the life of the Redmi Note 10 battery after the first charge
The first charge is just the beginning. To ensure that the Redmi Note 10 battery retains 80% of its capacity after 2 years, follow these rules:
💡
The optimal charge range for battery life is 30-80%, and constant charging up to 100% reduces the life of the battery by 15-20% per year.
| Action. | Impact on the battery | Recommendation |
|---|---|---|
| Use of fast charging (18W+) | Increases temperature, but slightly reduces the resource | It is allowed, but not daily. |
| Charging from a wireless station | 30% less efficient, heats the body | Use only as a last resort |
| Storage with 0% charge | It leads to deep discharge and failure. | If you don’t use it, charge up to 50% and turn it off. |
| Charging games | Battery temperature can exceed 50°C | Avoid or use a cooling stand |
The Redmi Note 10 has a hidden Battery Optimization feature that limits the background activity of applications.
- Go to Settings → Battery → Battery modes.
- Select "charge savings."
- Activate the “App Optimization” option (you may need to unlock additional settings through For Developers).
This mode reduces charge consumption by 10-15% without noticeable performance deterioration, but it disables background synchronization for some applications (such as mail or instant messengers), so use it only when necessary.
What if the battery is discharged quickly after the first charge?
