How to Fix My Samsung A70 and A71 Not Charging

By John Adebimitan

Have you plugged in your Samsung Galaxy A70 or A71, and it isn’t charging? Unfortunately, this is common, and there are various workarounds to it. The Samsung A70 and A71 are some of the best midrange Samsung Galaxy phones out there, and it packs a ton of features.

However, the phone may stop charging for several reasons. For example, you may be using an unsuitable cable or adapter, some third-party applications may interfere with the charging process, or some debris lodged in the phone’s micro USB port.

In this article, I’ll explain the possible causes and solutions when your Samsung A70 and A71 are not charging. The problem is also more likely to be a charger issue. So, I’ll be giving you some recommendations on the best chargers for your Samsung A70 and A71.

Possible Causes of Your Samsung A70 and A71 Not Charging

If your Samsung A70 and A71 are not charging, then the following are the likely causes:

#1. The charging port has an issue

The way the charging port of the Samsung A70 and A71 are designed makes them prone to charging issues. However, the charging port is type C, which means the hole is larger, and you can insert your cable end however you choose.

Lint or dust getting into the charging socket or improperly inserting the charger is very often responsible for the smartphone no longer recognizing the charger.

#2. You’re not using an original charger

Some smartphones are so selective of chargers that when you charge them with non-powerful, non-proprietary, or non-model-specific accessories, they tend to misbehave or perform slowly. For example, if you’re not using 45w and higher chargers or your charger isn’t type c to type c, your device might not charge.

#3. The charging cable is bad

If you’re sure the charging port of your adapter is in good condition and your phone will not charge at all, charges slowly, or charges and stops when you fondle with the cable, then the cable may be the problem.

Curling, stretching, matching, or putting the cable in your pocket can damage the cable.

#4. Your phone dropped in the water

The Samsung Galaxy A70 and A71 have no water resistance of any sort. So if your phone recently dropped in water, you may have charging issues, especially if water gets in the charging port or battery area.

If you drop your phone inside water, you’d have to send it to an authorized repair shop so they can have a look at it. However, a good home trick is inserting the phone into uncooked rice.

#5. Background apps

Some background apps may cause your phone to have charging issues. Samsung confirmed that some apps had been found to drain the Galaxy range of smartphones and tablets.

So, if you’re the type who likes to use the phone while charging, you may not see any difference, especially if you don’t have a fast charging cable.

#6. System problem

When your Samsung smartphone isn’t fully charging, it could be due to a system problem. If you’ve been ignoring the notifications for updates because of data needed, maybe it’s high time you decided to make an update.

An update can fix charging issues. It also goes the other way around. Perhaps you just made an update, and the problem started after that.

Then the problem might be the new operating system update, and you need to roll it back.

Samsung A70 and A71 Not Charging? Working Fixes to Try

You don’t have to rush to a repair center if you have the Samsung A70 and A71 not charging issues. The cause may be minor issues. You can try the following solutions at home:

Fix #1. Replace your phone’s charging port

This is the number 1 cause of charging issues in almost all phones. The charging port is likely bad if you confirm that your charger is in good condition and the problem persists. Then, a technician has to replace it from the board.

I recommend talking to Samsung support or taking it to the nearest local Samsung support center if your phone is still under warranty for a professional repair.

Otherwise, any experienced phone technician can replace the Type C charging port, and your charging issue will be resolved.

Fix #2. Clean the USB port of your charger 

If you have lint or dirt in your charger port and it’s not allowing the cable to contact fully, you can easily remove the dirt with a wooden or plastic toothpick.

However, never use electrically conductive metal materials. By the way, you shouldn’t do this while it’s plugged in too!

Or you can get electrocuted or create a short circuit that can damage the hardware irreparably. You can also use a compressed air duster or a brush to clean this charging socket.

Fix #3. Restart the device

As earlier mentioned, some background apps may cause your phone to have charging issues. Restarting the phone may solve the charging problem by stopping all background services.

Fix #4. Optimize your power-draining apps

As for background apps that drain the battery and cause charging issues, Samsung suggests that you optimize all apps or adjust app power management:

How to optimize all apps

  1. To optimize all apps, you must ensure your apps run on the latest versions.
  2. Then go to Device care on your phone
  3. Navigate to Settings
  4. Tap on Battery and device care
  5. Finally, tap on Optimize now, and all your apps will be automatically optimized

How to adjust app power management

  • First, head to Settings on your phone.
  • Tap on Battery and device care >> Battery >> Background usage limits.
  • Next, you need to adjust your settings as desired. You can choose from the following settings:
  • Choose Put unused apps to sleep so that apps not used for a while will be put to sleep automatically
  • Select Sleeping apps by choosing apps you don’t want to run in the background
  • By setting some apps as Deep sleeping apps, the selected apps will never work in the background except when opened

Fix #5. Check for software updates

When your Samsung smartphone isn’t fully charging, it could be due to a system problem. To fix this, make sure your phone has the latest software version.

By default, Auto update is enabled on Samsung Galaxy A70 and A71. This regularly checks whether an OTA update is available and then informs you. If you still want to check for an update manually, proceed as follows:

  1. Open the Settings app on your Samsung smartphone
  2. Switch to the Options tab at the top
  3. Go to the Device information menu.
  4. Now tap on Software update and then on Update now. The device now checks the Samsung servers for updates and downloads them if necessary.
  5. After the update is complete, click on Install. The update is now imported fully automatically, and the device restarts automatically. You should not use the smartphone and wait until it has completely restarted.

Fix #6. Try a different power source

Make sure the socket you use to charge the phone works by plugging something else and checking if it works.

Occasionally, a component in your home may be having electrical problems. Try alternative home outlets if you’re having trouble with your current outlet.

Fix #7. Replace the battery

Assuming you’ve done everything I’ve mentioned and still can’t charge your phone, it may be time to replace the battery. A phone’s battery life should last at least two years, although various factors can affect this.

But first, you can check the battery to see if it’s not leaking or swollen. Samsung Galaxy A70 and A71 are built-in and not easily removable. So if the battery is swollen, you must ask the technician to replace it. 

Fix #8. Replace your charging cable or charger

The problem can also come from the charging cable. So if there is any obvious damage to the cable, it’s time to replace it. But you may confirm this by charging your phone using another cable. Then, assuming it still doesn’t charge, the cable is not the problem.

Things to Do if Your Samsung A70 and A71 Is not Fast Charging

If your phone is charging, but it charges slowly, here are a few things you can do:

1.      Stop battery-draining apps

Another tip is to stop excessively draining applications that work in the background. Restarting your phone may stop them, but you can also set these apps to not work in the background.

2.      Update your device

Updating your operating system can also fix all charging issues. So when next you receive a notification for an OS update, accept it. Or you could do it manually by going to Settings >> Options >> Device information >> Software update >> Update now. After the update is complete, click on Install.

3.      Get a fast charger

If your Samsung device isn’t fast-charging, your phone charger is most likely ineffective. Perhaps it has had a short circuit, it is old, or you’re using a charger that is not designed for the phone.

These smartphones have a big battery (4,500 watts) and support 25W fast charging.

But, if you don’t find a charger to match this demand, the charging will be slow. So, the first tip is to get an original charger (I’ll be recommending the best models shortly after) and cable. 

Best Fast Chargers to Use for Your Samsung A70 and A71

Below are some of the best Samsung chargers that meet the minimum 25-watt output required by your Samsung A70 and A71:

1. Best for Samsung A70: Ubearkk 45W Super Fast Charger

The Ubearkk charger is a 45-watt charger that can take your phone battery to 68% within 30 minutes of charging. It is designed to work on Samsung Galaxy models, including the Samsung Galaxy A70.

There’s no information on whether this works for the A71, but it works for Samsung Galaxy A51, A52, A31, A32, A80, A90, A42, A50, A40, A41, A60, and A72.

The charger has a long 5 feet removable cable that can also be used as a data exchange cable. The connector type is Type C, which you have on the Samsung Galaxy A70 and A71.

In addition, the charger has various charging protection such as a voltage regulator, overcurrent prevention, short circuit protection, and temperature control.

2. Best Versatile Fast Charger: Sacrack USB C Fast Charger

The Sacrack USB C fast charger isn’t your regular phone charger. Instead, this is a 90 watts compact charging station with six ports, including USB C and USB A outlets. So, it’s not just suitable for your Samsung Galaxy A70 and A71 but also for iPhones, iPads, and more.

It charges at least three times faster than any old charger. It has 3 USB-C ports with a combined power of 60 watts, meaning you have 20 watts outputs for each port. In addition, there are three USB A outputs, delivering 10 watts of charging power.

This model also has a 5 feet AC cord. Like the Ubearkk charger, it has several charging protection features, such as a voltage regulator, overcurrent prevention, short circuit protection, and temperature control.

3.      Best Powerful Charger: INVZI 100W USB C Multiport Charger

This is it if you’re looking for a multi-port charger that also delivers high charging power for each port. Unlike the Sacrack charger, which has six ports but 10 to 20 watts outputs, the INVZI charger has 4 USB ports.

The first two type C ports deliver 100-watt output power each. Then there’s another Type C port with a 20-watt capacity for charging smaller phones.

Finally, the last port is a USB A with an 18-watt capacity. However, like the Sacrack charger, no USB cables come with this charger, which is why it’s not that expensive.

Meanwhile, this charger works for Samsung Galaxy phones and tabs. It also works for iPhones, Note, and Pixel phones. The Type C ports can also charge your laptops, specifically a MacBook Pro Air or a Dell XPS.

In Summary

If your Samsung Galaxy A70 or A71 phone won’t charge or fast-charge, it’s most likely due to an old, slow, or faulty charger (the adapter or cable). So, try getting a more powerful charger with an output power of at least 25 watts since that’s what these phones support.

And if it still won’t charge, it could be due to software issues or background apps. Try updating the operating system or downgrading if the problem started after updating the OS. You should also stop some apps from working in the background if you don’t need them running all the time.

And if you change to another charger and still will not charge, the charging port could be damaged. You should take it to the repairer or contact Samsung support.
