How to fix Oppo A37 not charging issues

Fix Oppo A37 Not Charging issues: Just like your vehicle needs fuel to run on, the battery of your Oppo A37s requires some fuel as well. Not as expensive as the automobile fuel though! This need not be clarified since we all are aware of the importance of charging your battery. Keeping these facts in mind, Developers all over the world are engaged in creating technology that modifies the battery power. But what if these all features get a stop on your device? That would be really annoying since you will not be able to operate your A37 normally or not at all.

Why does Oppo A37 not charge?

The reasons for this cause might be relative. They range from easy-to-tackle, not proper charging port to internal or battery issue that would take you to the nearby store for a complete technological repair.

At times, the A37 may not charge as it should or the charging speed may have slowed down. The power lasting capacity of your device may not remain as it was when you bought the A37. These all any many such related issues can be counted in as a problem for the A37 battery.

A damaged USB Port could be one reason that your A37 is not charging effectively in comparison to the time it takes. Another reason could be a third party app that you just installed and which has created some sort of havoc into your device. A software crash may be one reason for the slow charging issue. Faulty Cables or chargers or sockets or adapters can result in slower charging of your device.

Software Updates form one reason of defective charging on A37s. As the new advancements come along with the new update, although a device of newer version can take it positively, the older version at times fails to meet the demands and this ultimately results in a slower rate of charging.

For your problem of the Oppo A37s not charging, here is what you can try to bring it back to normal.

1. Check if the Power Supply is On

No matter how much every foolish this might be sounding right now but trust me, especially people, in hurry, simply forget to switch their power supply on and end up in complaining that the A37 has not charged since the time it was left for the same purpose.

This has happened with me like for a zillion times and I thought maybe you could relate too. Even if this does not happen with you, checking one would save your time for further processes.

2. Use Original Charging Sources

We all come across times when we do not have the charger or our device that came with the A37. And we then make use of some other device’s charger or even some duplicate cheap charger. This could cause a major harm to your Oppo A37s in all. Even if you are traveling, it is recommended to use a charger of your own and in case you use power banks, do use one that is original and safe by all means.

Duplicate chargers can only give you a bad result. Sticking to the original charger your manufacturer provided is the best thing to do.

3. Third-Party App causing hindrance in Charging

Installing a third party application may cause your Oppo A37s to gain a slower charging rate. The apps may sometimes come with some sort of virus or malware or may simply be technologically incompatible with your device and this can have a severe effect on the battery of your device.

The app may cause some internal hindrance resulting in poor charging rate. For times like this or whenever you suspect an app causing a disturbance, you can clarify and check those yourselves by booting your device into Safe Mode. With the Safe Mode on in your device, you can detect whether an app is a reason for the slower charging of your device.


You can Enter the Safe Mode on your Oppo A37s by Holding the Power Button of your device for a few seconds till the small pop up window appears on the screen. Then hold down the Power Off option on the small window for a few seconds as well. This will introduce another confirmation box message that would read if you want to boot your A37 into the safe mode. Tap Ok for the Confirmation and your device will boot into Safe mode. You can know this when the device restarts and you see a sort of tag at the bottom left corner of the screen.

4. Software Update can lower the Charging Rate

When a Software Update is introduced in an older version or device, the device may be incapable of the higher demands of that improved software. This results in a slower rate of charging as compared to earlier and with time this may even become more severe.

What you can do to prevent this issue is that you can rollback the update to the older version of your device. This will in most of the cases solve the problem over there itself. Though it is stated that the risk of your device’s safety is enhanced without an update but the assurance of this is negligible in front of what damage it can cause to your battery and usage.

5. USB Port Fix

One of the reasons could be quite a damaged internal metallic surface of either the battery slot or the USB Port of Oppo A37s. Maybe there is not happening a good contact between the between the charger and the port. The reason for this cause may be a minor manufacturer mistake or continuous usage of the port for charging the A37.

What you can do to fix this issue is- Shut down your device and remove the battery if your device battery is removable. You can either use the SIM card trigger or any toothpick to just slightly lever up the tab inside the USB port of your device. We may find this slight ineffective but for most times this is what needs to be done to fix the problem.

6. Battery dropped in Water

One of the most annoying situations you could have is the battery problem caused due to falling or coming in contact with water. Even though it seems that water contact did not affect it much and your A37 is still working, chances might be that the battery has ruined because of the water.

For situations like this what you can try is- change the battery and use another one and also once check if the water has not harmed the USB Port or any other internal part of the device.

7. Simply Switch it off

For people working in an office or students at college do not really need mobile A37s in most of the cases. Though nowadays everybody is attached to their A37s like some magnet, you can switch your device off while not working on it.

I would recommend this method especially while charging your device. When you have the charger plugged in your device and there is no need to make any use of it, you can let it have a short rest. if there is something urgent that has to be done with, you can use the A37 for the emergency and then again switch it off. This will ensure a better way of charging and hence keep the battery life safe.

8. Replace the Battery

This will be stupid to mention but as you know batteries have a lifetime limited to a period of a couple of years or rarely four to five. But with the increased lifespan, just as humans a certain stage in the lifetime of a battery could result in decreased efficiency of the battery to charge as it would do earlier.

Another effect happening on your battery is the intensity o charging it. The more you charge your battery the more it turns old.

At times you can know that by the bursting of the battery. Also, you can easily detect when a battery is no more reliable when you see some sort of fluid coming out of it. If you won a device whose battery is not removable, you can try spinning the A37 on its backside and watch it horizontally over the surface, you will come to know if it has bulged.

If the battery has been used since two years or more, then its time you have to expel it and bring a new one. Make sure the new one is the original one as well and do not even consider buying a cheap battery to save some bucks. This is something you need to invest on for a better future usage.

9. Use Effective devices

If you are charging your Oppo A37s via the laptop then you cannot expect it to charge as fast as it does not give you any good results, universally. If you are not aware, the wall sockets deliver more power from the source than our traditional chargers which carry comparatively lesser electricity.

Hence it is essential to use a smarter source for your smartA37. If you find the traditional chargers less useful you can shift to the wall sockets. The only thing you need to keep in mind is to take the appropriate wall socket for your device. Do not just go and pick any.

10. Try Switching Cables

The cables are the most sensitive part in any charging system, to be honest. A slight damage to them and they affect your whole charging machinery. Abysmal cables can reduce the charging power by a really large quantity. Despite the endless torment of curling and cramming the cables into small places, you will notice that the cables last longer than expected every time.

Cables are for sure resistant but a continuous use of them would only make them vulnerable. Shifting in between two or three cables can give you a good battery charging rate and take care of the cables as well. The choice to choose obviously depends on your hands, but if you do follow this method you will see only good results. Provided, the cables other than the one your manufacturer provided should be of a good quality and working and the ones that are compatible with your Oppo A37s.

If you Use some poor cheap quality cables, you will end up with no good and probably bad results.

Just like we need some new place to visit or something new every now and then to keep hustling, a change in power source could work as the same for your hard-working battery.

If you are using the same charger ever since you started using your device consistently, it is high time you shift to some other source for charging even though your charger works good, there might be effects unseen to the naked eye. The charger with the regular use may have by now reduced efficiency to work. But do note that whatever other power sources you shift to, it should be reliable and original.
