Today, I had a truly unique experience with a Xiaomi Redmi Note 8. Honestly, Redmi issues can be quite strange.

A customer came to me with a Redmi Note 8 that was stuck in an automatic restart loop. The phone would show the white Redmi logo on the screen, shut down, then restart again in the same cycle. Even when connecting the charger, it initially showed the charging icon, but as soon as you tried to power it on, the same problem came back.

What’s the solution? And where is the fault?

At first glance, I suspected a software issue and thought it might be a system glitch. Naturally, I didn’t hesitate and performed a factory reset on Redmi Note 8. I waited until the formatting process was completed but unfortunately, the problem was still there. That confirmed the issue was on the hardware side.

I started checking the buttons, because in many similar cases this issue is related to faulty buttons, especially the power key. I carefully inspected them and tested them using a multimeter. Everything was working perfectly with no faults.

I kept thinking about the cause and told myself it might actually be the battery. Redmi phones are notorious for battery problems, and we often don’t suspect them because they can fail without swelling.

I brought a brand-new battery for the Xiaomi Redmi Note 8, replaced the old one, and the phone powered on as if it were new. It was great news the issue was with the battery, and I honestly didn’t expect that outcome.

Finally, the problem was solved and the phone is now working normally without any issues.

That’s why I wanted to share this experience with you, my dear followers. If you encounter the same problem, try replacing the battery first before doing a factory reset, unlike what happened to me personally.

Common Symptoms of the Redmi Note 8 Auto-Restart Issue

When a Redmi Note 8 suffers from a boot loop or automatic restart problem, users may notice:

The Redmi logo appears, then the device powers off and restarts repeatedly.
Charging appears to work at first, but the issue returns once the phone is powered on.
The device never fully boots into the system.
Factory reset does not resolve the issue.

These signs often make users assume a firmware problem, but that’s not always the case.

Initial Troubleshooting Steps

Most technicians or users try software-related fixes first:

Performing a factory reset
Flashing stock firmware
Updating the MIUI system

However, when the issue persists after formatting, this is a strong indicator that the problem may be linked to **hardware rather than software**.

Why Hardware Can Be the Real Cause

Several hardware components can trigger continuous restarts:

Power button malfunction
Short circuits on the motherboard
Faulty battery connection or damaged flex cable
Dead or unstable battery

In Redmi phones specifically, the **battery is one of the most common causes**, even when it shows no swelling or physical damage.

Hardware Diagnosis: What to Check First

Based on real repair cases, here are the priority steps:

Inspect the Power Button

Use a multimeter to confirm if it's not stuck or shorted.

Check Internal Connections

Loose or oxidized connectors can also produce boot loops.

Test the Battery

Even if the battery looks normal, it may no longer provide stable current during startup. Redmi devices are known to restart when the battery voltage drops during the boot process.

The Real Fix: Battery Replacement

In many situations just like the one described in the introduction the **battery is the root cause**. Replacing it with a new, original, or high-quality compatible battery often solves the boot loop instantly.

After installing the new battery, the Redmi Note 8:

Boots normally
Stops restarting
Charges correctly

Performs like a new device

This solution is fast, inexpensive, and avoids unnecessary formatting or flashing.

Why You Should Try the Battery Before Formatting

Many technicians waste time resetting the phone or flashing software. Instead, testing with a new battery first can:

Save hours of work
Avoid data loss
Prevent unnecessary stress for the client
Confirm whether the issue is power-related

If the device powers on successfully with a replacement battery, no further steps are needed.

Final Tips for Technicians and Users

Don’t assume all restart problems are software-related.
If formatting doesn't help, move quickly to hardware inspection.
Replace or test with a known-good battery before opening the motherboard.
Don’t wait for the battery to swell some fail silently.
Always use an original or high-quality replacement.

Conclusion and Final Insight

This experience is a crucial reminder that faulty firmware or software bugs are not always the source of boot loop problems and forced restarts on Xiaomi Redmi devices. Although many customers think that flashing, formatting, or factory resetting will solve the issue right away, hardware issues, particularly with the battery, are frequently the root reason.

In the previously mentioned instance, the problem was immediately fixed by changing the battery, demonstrating that internal battery failure and startup interruption can occur even in the absence of outward damage or swelling.

It’s also important to understand that this issue is not limited to the Redmi Note 8. The same behavior can occur on various Redmi models such as the Redmi Note 7, Note 9, Note 10, Redmi 8A, Redmi 9C, Redmi 10, and others.

Many Xiaomi phones share similar power management systems, and a weak or unstable battery can trigger the same restart loop across different devices. For this reason, anyone facing this problem should always consider testing or replacing the battery before moving on to more advanced procedures like firmware flashing or motherboard repair. This approach saves time, preserves data, and often solves the issue more effectively than software-based solutions.

If technicians and users adopt this mindset checking hardware first, especially the battery they can avoid unnecessary frustration and quickly identify the true cause of the malfunction. In short, a simple battery replacement may be the key to fixing what appears to be a complex reboot problem across multiple Redmi models.
