This element is one of the most sensitive of any smartphone. Much of its useful life and degradation depends on the user’s hand. OPPO mobiles have the best fast charge on the market, but their batteries are not without problems either, as we will see below.
There are many faults that can occur with the use of the phone’s battery. As with screen problems, in OPPO mobiles that present these problems, the most common is that the phone stops charging or does so more slowly. In this case and before going to the Technical Service, there are several points that we can review ourselves to rule out the guilty. The Chinese firm itself recommends taking these points into account before blaming this component of the terminal.

Why is the battery bad
Like any component of a smartphone, the degradation of the mobile battery is something that worries us, and a lot. But, before this circumstance, the only thing we can do is take certain measures so that it lasts as long as possible. However, if it runs out earlier or takes longer to charge to 100% from one day to the next, it will be more rare.

If your problem has been showing itself over time, it will be more than clear that the error will not be from your charger, nor from the terminal itself, but rather that the useful life of the battery is coming to an end . Therefore, the only solution that we find in this situation will be to replace this component of the terminal.
To find out if it is a problem with this element, you can make use of the Phone Manager that is integrated into all mobiles of this brand with ColorOS . To do this, you will need to search for this app > tap on Diagnostics. Then, choose the Battery and charging option (you will need to connect the smartphone to the charger) > click Run . If there is any failure in this component, it will tell us. As it will notify us if everything is in order.
In case everything is ok, you’d better take a look at the following solutions to fix OPPO battery issues.
Operating system settings
In order to improve the autonomy of a smartphone, we must always make use of all the tools that OPPO phones themselves offer us within their operating system. So, if you want to save battery on your mobile, you better take a look at these tips.
control the use
To determine if there are faults with the mobile battery or not, it is best to take a look at the use we make of the phone. Well, there, we will see if there really is a problem or if it is directly that we are making excessive use of the phone.

To see this information, we will have to go to Settings> Battery and tap on the Use option. At that moment, different elements will be displayed that will be the apps that consume the most energy on the smartphone. If an app doesn’t work for you because you never use it, your best bet is to remove or update it, just in case it’s a software optimization issue.
Optimize the battery
Within phones with ColorOS we find tools with which we can improve OPPO’s autonomy. In this way, we will ensure that the energy of the smartphone is much higher, and we may be able to get rid of the battery problems of the mobile .

To do this, we will have to go to Settings> Battery> Advanced settings. Within this section, we must enable Sleep optimization, with which the phone will spend less energy, and then click on Optimize use. Inside, we must click on the apps and select the option to Optimize automatically .
Pay attention to ColorOS
If you do not know very well what to do to be able to increase the battery of the OPPO mobile , we recommend that you pay attention directly to the advice that the ColorOS operating system will give you.

Within the Settings> Battery section, you will find a tab with recommendations at the top. By clicking on it, we will enter a menu that will offer us a series of options so that we can gain more energy on the phone, it will be as you can see in the previous image. And it is that, in this way, you will be able to save battery on an OPPO mobile easily.
Other solutions
It is clear that nobody likes to go through these situations. But, the truth is that it can happen to us at any time, from the simple fact that the OPPO phone does not charge, until it makes it slower than normal. For this reason, we are going to give a series of instructions that you must follow to find the solution to your problem.
Use the original cable
OPPO’s charging , including fast charging, is one of the best on the market, but we have to keep in mind that its performance will be adequate only when we charge the terminal with the original charging cable and USB adapter. Third party accessories may not be compatible and may cause battery failure.
So, if you have recently changed this accessory on your smartphone for one that is not original, it is likely that there is the problem that has caused it to not charge as fast as before. And, even, it has been able to damage the OPPO battery .

Check for damage
Another step is to check that both the charging cable and the USB adapter have no damage such as breaks or bent ends . If we see something similar, we should not use those accessories and we should try another charging cable and USB adapter that we have in case, and then try again.
And not only this, but the culprit could be the port of the phone itself. So we will have to clean it, to see if the problem is that too much dirt has accumulated inside it, which is preventing it from connecting well to the charger. Clean it by blowing, being careful not to expel drops of saliva, or with a small pointed object that removes any dust that may be inside. And beware, do not do it too hard so as not to end up really damaging it.
change take
In addition, it will also be a good idea to connect it to different outlets in the house, because like everything in life, it may have been damaged. So, to check whether it is a mobile battery issue or not, try changing the wall outlet .
When changing the plug we will see if the error lies here. It is very common for power strips and extension cords to have problems after a while.

Check the connection
In the same way, being connected to a wall outlet, or if we have connected it to the computer, we will have to check if the connection is firm between the charging cable, the USB wall adapter and the wall outlet. If everything is firmly connected, we will have to find another solution.
Check the temperature
These elements are lithium, so, being made of this material, they are very sensitive to temperature. The high ones can cause its degradation if it is loaded at 45 degrees or more. Additionally, downtimes can increase the internal resistance of this component, causing a slower charge, so it will take longer to reach 100% capacity.

To prevent damage, OPPO smartphone will automatically stop charging at extreme ambient temperatures. This usually happens, for example, when playing while the terminal is charging and the ambient temperature is higher, usually in summer.
If you want to see for yourself what temperature the OPPO mobile battery is at, you can download the Device Information app from Google Play. Within the ‘ Battery ‘ section, you will see what degrees it is at that moment:
Close background apps
Apps running in the background can drain power on many occasions. To try to increase the performance of the battery or its charging time, it is recommended to close them. To do this we touch the menu button and press the ‘X’ to close all applications in the background.

Don’t use it while charging
This recommendation is something that is common to all manufacturers including OPPO. And it is that, using it at the same time, means that the effect of loading and unloading counteracts, therefore, the loading time is extended. Also, keeping the phone in the charging and discharging state simultaneously causes battery performance degradation.
Manage loads well
It is not recommended to fully charge or discharge the mobile. When the battery is completely empty , it could fall into a state of deep discharge, this makes it unable to hold a charge. On the other hand, if we connect the smartphone to power after it is fully charged for a long time, this component may lose capacity, which shortens the life of this component.
Software bug?
Another of the most common errors that mobile users will have to face is the happy smartphone software. In these cases, after checking that it is not the fault of the apps, you should see if the phone’s operating system is to blame. To do this, it is best to update the mobile (Settings> Software update ), if it has any available firmware, or format the terminal to correct the error that has caused a recent update.
Before you reset your phone , make a backup. After doing it, go to Settings > Additional settings > Backup and reset > Restore factory settings.
