Why Xiaomi Redmi Note 10 is discharged at night: a full analysis of the reasons

The situation where Xiaomi Redmi Note 10 loses a significant percentage of battery power during night downtime is familiar to many owners: you go to bed with 85% on the indicator, and wake up with 60%, even though no one has used the phone. It's not just a minor inconvenience, but a signal that the system is running resource-intensive processes that should not work in the background.

The self-discharge phenomenon is often associated with the MIUI operating system, which aggressively tries to sync data while the device's screen is off. However, don't blame the hardware or battery wear right away. Most of the time, the problem lies in software settings that require your intervention to optimize.

Next, we will discuss in detail the technical reasons for this behavior of the smartphone, the methods of diagnosis and the specific steps to eliminate the power leak, and understanding these processes will help to prolong the autonomy of your device and avoid deep discharge.

Background activity of Google apps and services

The main reason Redmi Note 10 runs out at night is the incorrect operation of the background applications. Even if you closed all the windows, many programs continue to hang in RAM and periodically activate the processor to receive notifications or update content, especially social networks and messengers that are not configured for energy saving.

Google Play Services can also be a high-consumption service, responsible for geolocation, email sync, and app store operation, and sometimes syncs get stuck and start cycling to connect to the server, draining battery power and heating the case, a common problem after system upgrades.

To identify the culprit, you need to go to the battery consumption statistics, and you'll see a list of apps that are sorted by energy consumption, and if there's an app at the top of the list that you didn't use before bedtime, it's the one that's blocking your smartphone from going to sleep.

• 📱 Social networks (Instagram, TikTok) often update the feed in the background, even if notifications are disabled.
• 📧 Email clients can try to download "heavy" attachments with a weak Wi-Fi signal.
• 🗺️ Navigation services sometimes do not close access to the GPS-The module continues to track the location.
• ☁️ Cloud storage (Google Photos, Mi Cloud) can start backing up your gallery at night.

⚠️ Warning: If you notice your phone warming up in the camera or processor area during downtime, check the running processes immediately. Prolonged heating is harmful to the chemistry of the lithium polymer battery and can cause it to bloat.

Problems with mobile communication and network search

One of the most hidden but energy-intensive causes of discharge is a weak cellular signal. If you live in an unstable reception area or the walls of your house screen the signal, the Xiaomi Redmi Note 10 has to constantly increase the power of the transmitter. The communication module runs at its limit, trying to maintain a connection to the base station, which leads to rapid battery depletion.

During the night when you sleep, your phone may constantly switch between communication standards (e.g., with a phone or phone). 4G on 3G And then you can look for the network if the signal goes away, and this is called ping-pong, and you can actually consume a lot of energy, and you can visually see it by the flashing indicator of the network, or by the E icon instead of the E «4G/LTE».

The solution may be to turn on overnight flight mode if you don’t need to call the craps, or to force the switch to “Only” mode. 3G/2G», if 4G It's not good. It's also worth checking the settings. SIM-If there are two cards, the second SIM in the area of poor reception can be the main energy devourer.

You can use an engineering menu to force a change in the type of network, but it requires caution. A safer way is to use standard settings:

→ SIM-maps and mobile networks → Preferred network type

Choose an option that is stable in your location, even if the Internet speed is lower. A stable 3G connection consumes less power than the constant jumps between 4G and E.

Features of the screen Always on Display

The feature is Always on Display (AOD) — It's a beautiful widget that shows the time and notifications on the screen that's off. AMOLED-It's a matrix where each pixel is lit independently, and although it's considered energy efficient, it puts a lot of stress on the battery at 8 a.m., and thousands of pixels are running.

The problem is compounded by the Always On mode, which is a continuous screen, and a more sensible approach is to use 10 seconds after touch or Schedule mode, which many users forget to set up after purchase, leaving the phone in a constant glow mode.

Also worth paying attention to is the style of the watch: complex animated dials require more energy to render than static prime numbers. If your goal is maximum autonomy, it's better to give up AOD completely or limit it to night time.

The Influence of Widgets and Live Wallpaper

The MIUI shell offers many ways to personalize, but they come at a price. Live wallpaper (video wallpaper) continues to consume CPU and GPU resources even on a locked screen, as the system must support their playback in the buffer. This is a direct route to discharge overnight.

Desktop widgets, especially those that are updated in real time (weather, currency rates, news), also wake up the phone. Each data update requires you to turn on a Wi-Fi module or mobile Internet, process the data packet and redraw the interface, and there can be dozens of such cycles overnight.

It's recommended that you do a desktop revision, leave only static widgets and install regular, non-animated wallpaper, which not only saves you charge, but also speeds up the interface when you wake up the device.

Synchronization settings and accounts

Synchronizing your Google account and Mi Account data is an important process, but it needs to be optimized. If you have a lot of photos, contacts, or notes, your phone may try to download them all at once when Wi-Fi appears. At night, when your phone is connected to your home network, this process can be activated and last for hours.

A common error is the enabled synchronization for all types of data, including those that are not needed constantly (for example, synchronizing Play Games data or Google Drive in the background).

You need to go to your account settings and selectively disable sync for rarely used services. Also check your Google Photo settings: if backup is enabled in the original quality, the phone will waste a lot of energy processing and downloading files.

Diagnostics and reset network settings

If the software methods didn’t help, network protocol errors may have accumulated in the system: resetting the network won’t delete your personal data (photos, contacts), but will return the Wi-Fi, Bluetooth and mobile Internet settings to factory values, often solving problems with sticking in the communication modules.

Once reset, the phone will reconnect to the towers and router, which can eliminate background errors that cause the discharge, and it is also worth checking for system updates, as newer versions of MIUI often come out with patches that fix power problems.

As a last resort, if the discharge remains critical (more than 20% per night without use), it is worth considering a complete reset to factory settings.

⚠️ Note: Before resetting your network settings, make sure you remember passwords from your Wi-Fi networks, as they will have to be re-entered.

💡

Use Second Space or Guest Mode for the night, run your phone in a clean profile without apps installed, and leave it overnight, and if you don't discharge, it means that one of the apps you installed is the problem.

💡

The main reason for the night discharge of the Redmi Note 10 is not battery wear, but the background activity of applications and unstable communication signal, which prevent the phone from going into deep sleep.
