My mobile is charging slowly and discharging quickly
What you should keep in mind is that there is no specific solution to fix this problem. Especially if you can't physically manipulate the device to see what could cause it to load slowly and download too fast. However, we can suggest some things so that you can draw your own conclusions and solve the problem.
Check the loading speed
The first thing we're going to do is use the Ampere app. The application gives us a lot of information on the charging speed in amperes, we can see all this in real time. Generally the figure should be kept between 1.000 Ah and 2.000 Ah.
Conversely, if you use fast charging, it will be higher: from 3.000 to 4.000 Ah. What we will do is charge the device and leave the application open to check the loading speed. In case it is less than 1.000 Ah, then we have clear what the problem is: the cable or the charger.
In this case you should try another cable and charger. As far as possible, they are originals from that company. However, you can try anyone to get rid of your doubts.
My phone takes a long time to charge and the battery doesn't last
Be careful with the charger
Following a little of what we have told you previously. It is essential to lend be very careful with the charger. Many people use whatever charger they have available.
You may not have any kind of problem at first. However, you will gradually notice that the phone starts to have one or the other drama. It discharges faster than usual, the battery does not reach 100%, the charging speed is slower, etc.
You should always use the original charger. In extreme cases where you don't have a charger on hand, you may want to use the one that is nearby. But this should be every now and then, not always.
USB connector or charging PIN
On many occasions, simply by cleaning the charging pin or USB connector, the device starts charging normally. To clean it and get rid of your doubts, what you should do is take a toothbrush with soft bristles and lightly moisten it with isopropyl alcohol. Obviously, in order to clean the phone we have to turn it off beforehand. If you don't, you will end up damaging it.
My mobile phone battery runs out very quickly
In case your mobile phone battery runs out too fast. We are about to install an application called GSam Baterry Monitor. It is used to have precise data and graphs on the use of the battery and on all the applications that concern it. But not only that, but we will also see how it affects the mobile network, the screen, the processor, etc.
Once installed, we should have the app open in the background for see the graphs in question and be able to draw our own conclusions.
Remember that having mobile data is not the same as having Wi-Fi. The former consumes much more battery than the latter. Also, if you have activated all connections such as Bluetooth, Wi-Fi, mobile data, NFC, geolocation or GPS, etc. The battery will last you next to nothing.
In case you can't find a solution. Before taking your device for service, we recommend that you try a factory data reset. Maybe some app you have installed or some malware is bothering you. When you do a hard reset, you leave your phone as if you just bought it in terms of software.
So if it's a software problem, with a format you'll fix it. The only thing we recommend before doing this is to make a backup, as all your personal data is deleted.
Factory reset can be done from the settings menu. Although we recommend that you fully charge your phone before doing this.
