The worst nightmare of all phone owners is not that the phone runs out of updates or not finding the perfect case. What terrifies us all is trying to turn on the phone and find that nothing is wrong. A black screen with no apparent sign of life on the smartphone.
A problem that is further aggravated if we verify that not only does it not turn on, but that the mobile does not charge either. Then we will ask ourselves the question: Why does our mobile phone not turn on? Below we review the main causes of this problem and what would be the possible solutions to bring the phone back to life.
Is the problem in the battery?
The first possible errors that we are going to find have a place in the battery, which is the culprit in most cases that the smartphone does not respond, therefore it neither turns on nor has it been able to start charging it.
We start with the charging system
The first thing we have to check is the plug and the charging connector. Since these are usually the ones that cause our mobile to not be able to recognize the energy input and therefore if the battery has been exhausted, it will not be recovered for a long time that it is connected to the current.
But we must not overlook the charging cable, which is as important or more important than the connector itself that goes to the wall. To make sure it doesn’t fail, we can test it with another smartphone or device. In this way we will leave doubts to find out if the fault is in our battery or in the point of union between both.
Beware of dirt
The problems that lead us to the mobile battery not reacting, many times it is due to the fact that the battery or the connection itself do not make contact with each other. In this case, what we will think is that there is dust, dirt, grime or other obstruction in the charging port of the phone. To get out of this situation there is nothing better than a quick blow, carefully pass a pin to the connector and then try it again.
If your Android phone won’t turn on despite doing everything we’ve seen so far, one solution is to perform a battery cycle reset. For devices with a removable battery, it’s as easy as taking it out, waiting a few seconds, and putting it back in. If your smartphone does not have a removable battery as is the case in most cases, press and hold the devices power button for several seconds.
Depending on the manufacturer, you should hold it like this for 10 to 30 seconds. The more the merrier, until some image or logo appears on the screen. This will not be impossible even if the mobile seems to have no battery, as there is always a small emergency percentage for these cases.
Then we reconnect the phone to the charger and wait a minute to see if the charging icon appears on the screen. If the icon does not appear or we see a charging led, it means that the battery does not have enough power to turn on or display any content on the screen. Let the mobile charge for a few more minutes and then try again. If you continue to exit, the battery is dead. In case we see any reaction, we will have to think that the battery is fine and we will focus on the mobile.
Is the problem in the mobile itself?
Even if you haven’t thought about it, your phone may be on without you noticing. It could be that the problem is that the screen is broken and does not show any image. Fortunately, it’s easy to tell if the screen is the culprit. To do this, hold the power button for 30 seconds to turn off the mobile and press again to turn on the mobile and start the system.
Now wait for the smartphone to make a sound or simply call yourself from another number to see (if it is not muted) if the mobile rings. Another way to verify that the screen is the culprit is to connect the mobile phone to the computer, if we are able to control it, this will mean not only that the mobile is not dead, but that we can take all the photos, files and important elements before have the screen repaired.
If even after trying all this, you still see that the mobile does not turn on, we can try to return the smartphone to its factory state. Perhaps the device will power on in this process, but it cannot go beyond the boot process due to a corrupt update or improperly installed ROM. In this case, you can try to reset the device by doing a Hard Reset.
- Press and hold the power button and the volume down button for a few seconds until the Android logo appears on the screen (Miracle, it turns on!)
- Use the volume buttons to navigate up and down in the recovery mode.
- Select Wipe Data / Factory Reset and press the power button to accept.
- Lastly, select Erase all data option and press the power button one more time.
- Wait for the phone to restart.
- This should bring your mobile back to life, but if not, we may be facing a hardware failure whose origin is in the battery or another component and it touches you, or take the mobile to repair or buy a new one.
- We do not have to put ourselves in the worst, since sometimes the only thing that has happened and that will be solved in the technical service, is that the battery has been disconnected from the motherboard and does not receive the signal. But those steps will be better left in the hands of professionals, because touching the battery, even with the right tools, can cause a short circuit that breaks the mobile forever and puts us in danger.
