Xiaomi Redmi 7A is one of the brandβs most popular budget phones, but even it sometimes refuses to turn on. The reasons can range from a dead battery to software failures after an upgrade. In this article, weβll look at all the possible ways to turn on the phone, from basic to emergency when the device does not respond to the power button.
It's important to understand that the algorithm of actions depends on the symptoms: whether the charging indicator flashes, whether the phone vibrates when you connect to the network, or the screen remains completely black. We will look at each situation separately so that you can determine exactly what to do next. If your Redmi 7A does not turn on after a drop or moisture hits, this is already the case for the service center, but in 80% of cases the problem can be solved independently.
This article is relevant for all versions of MIUI 12, 13 and 14, as well as for Redmi 7A modifications with 2/16 GB and 2/32 GB of memory. Instructions are universal and will work even if the phone has been lying idle for a long time or was reset to factory settings.
1. Standard Turn on: What to do if the phone is turned off
If Redmi 7A is shut down normally (for example, after discharge or on your command), it is enough to turn it on:
- Connect the phone to the charger for 10-15 minutes (even if the indicator is not on).
- Press the Power button (located on the right end) for 5-7 seconds until the Redmi logo appears.
- Wait for the full load of the system (can take up to 2-3 minutes, if you have not turned on for a long time).
If the screen is black after this, check:
- π Charger and cable: try another ROM with output 5V/2A (Original adapter from Redmi 7A has such parameters).
- π Battery status: If the phone was discharged for more than a month, the battery could go into "deep discharge" and not take charging.
- π± External damage: cracks on the body, traces of oxidation in the connector USB-C or battery bloating (seen if slightly pressed on the back cover).

If the charging indicator flashes red, but the phone doesnβt turn on, itβs a sign of a critically low battery.
If you see a red light after you're connected to charging, and it goes off after a few seconds, that's a signal that the power controller is completely discharged, and then you can only light it from another phone through the lights. OTG-cable or use of a special booster for Li-ion batteries.
2. Forced reset (Hard Reset)
If the Redmi 7A is getting stuck on the Mi logo, the screen flickers or the phone doesn't respond to taps, but the indicator vibrates or burns β forced reboot will help. This method resets temporary data in RAM, but does not affect user files.
Instructions:
- Press the Power button + the Volume button up at the same time.
- Hold for 10-15 seconds until the screen goes out and the phone vibrates.
- Release the buttons and wait for the automatic reboot (can take up to 1 minute).
If the combination does not work, try an alternative:
- π Squeeze the power. + Loudness down 20 seconds (to double vibration).
- π If the phone is connected to charging, disconnect the cable before manipulation.
Turn off the charger |
Make sure the buttons are not stuck |
Try the combination 2-3 times with an interval of 10 seconds |
If it doesnβt help, go to Recovery.

β οΈ Warning: Donβt confuse forced reboot with factory reset! Hard Reset doesnβt delete data, whereas Wipe Data in Recovery erases everything from internal memory.
3. Enable via Recovery Mode (if the phone doesn't respond)
If the Redmi 7A doesnβt turn on even after a forced reboot, the next step is to launch in Recovery Mode.
- π§ Restore the system after an update failure.
- π¦ Delete corrupted cache files (without data loss).
- π Return the phone to factory settings (if other methods did not help).
How to log in to Recovery:
- Turn off the phone (if it is on, press the power for 10 seconds).
- Press Power + Volume up and hold until the Mi logo appears.
- Release the Power button, but keep Volume up until you see the Recovery menu.
In the Recovery menu, use volume buttons for navigation and power for confirmation.
| Option. | Description | Effects of consequences |
|---|---|---|
| Reboot | Phone reboot | Safe exit without modification |
| Wipe Data | Reset to factory settings | Delete all data except files on SD-map |
| Wipe Cache | Cleaning the cache system | Safe, does not affect personal files |
| Connect with MiAssistant | Connecting to a PC for recovery | Requires official Mi Flash Tool software |
If you chose Wipe Cache, the phone will automatically restart after cleaning the cache, and if you had to do Wipe Data, you'll need to set the phone up as new.

4. Enable via Fastboot (for advanced users)
Fastboot is a low-level boot mode that allows you to stream your phone through your computer, and you need it if you:
- π± The phone doesnβt even load in Recovery.
- π There was a failure when updating the firmware.
- π οΈ Reinstallation required MIUI zero.
How to log in to Fastboot:
- Turn off the phone (remove the battery if necessary if it is removable).
- Press Power + Volume down for 10-15 seconds.
- Release the buttons when the image of a hare in a hat-eared hat appears on the screen (Fastboot logo).
Further action will require:
- π₯οΈ Computer with Qualcomm drivers and Mi Flash Tool.
- π Official firmware for Redmi 7A (You can download it from en.miui.com).
- π Cable USB (preferably original).
β οΈ Note: Fastboot Flashing removes all data from your phone, including photos and apps. If there were important files on the internal memory, try extracting them first. ADB (If the phone is determined by a computer).
Yeah, I did.|
No, but I want to learn |
I tried it, but it didn't work.|
I've never heard of that.

5.Battery problems: how to "resuscitate" a fully discharged phone
If the Redmi 7A does not turn on and respond to charging, the problem may be deep battery discharge. Lithium-ion batteries after full discharge (below 2.5V) are locked by the controller, and standard RAM does not "see" them.
Method 1: "Lightning" from another phone
- Take a working smartphone with OTG support (like another Xiaomi).
- Put Redmi on it. 7A through OTG-cable USB-C β USB-C).
- Press on the discharged phone Power + Volume up for 20-30 seconds.
- If the charging indicator flashed - connect the phone to the socket for 1-2 hours.
Method 2: Using a booster for Li-ion batteries
If OTG doesnβt help, youβll need a special device (such as the iMax B6 or SkyRC MC3000) that can deliver current directly to the battery contacts.
- π§ Carefully remove the Redmi back cover 7A (It's on the latches, but be careful with the plumes!).
- π Find the battery contacts: + (red) and - (black).
- β‘ Connect the booster in Li-ion mode 3.7V currenty 0.5A 5-10 minutes.
π‘
If you light up the phone, but it's running out quickly, replace the battery. Deep discharge reduces battery capacity by 20 to 30 percent.
β οΈ Note: Do not try to charge the battery directly from the power supply 5V It can cause fire, and only use specialised devices with anti-pole protection.
6. Hardware malfunctions: when to carry in the service
If none of these methods worked, the problem is probably hardware.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| The phone heats up when charging, but does not turn on | Short circuit on the board or failure of the power controller | Diagnostics in the service (repair from 1500) β½) |
| The screen remains black, but the phone vibrates when connected to the RAM | Damage to the display or matrix plume | Screen replacement (from 2500) β½) |
| Charging indicator flashes white/green, but the phone does not load | Firmware failure or damage to the boot partition | Flip-through EDL (1,000 β½) |
| The phone is only turned on when connected to the ZU | Battery wear (capacity < 50% of nominal value) | Battery replacement (from 800) β½) |
If you suspect a hardware malfunction, don't try to disassemble the phone yourself - the Redmi 7A has brittle plumes and is easily damaged when a sloppy autopsy is done. At Xiaomi service centers, diagnostics are usually free and repairs are cheaper than buying a new phone.
The cost of repairs in 2026:
- π Battery replacement: 800β1200 β½ (original or 500-700 β½ (analogue).
- π± Display replacement: 2500β3500 β½ (touchscreen).
- π§ Repair of the board (sweeping of the power controller): from 2000 β½.
- π₯οΈ Flip-through EDL: 1000β1500 β½.

If the phone falls into the water, DO NOT turn it on or plug it into a charger! The longer it stays off, the better the chances of recovery.
