#1 SOUR BATTERY
The most common reason that the Android smatphone refuses to turn on is a battery that has run out to zero. A common reason “why the phone does not turn on Android” is a fully discharged battery.
The solution here is simple – connect the smartphone to the charger. Please note that with an empty battery, it may take a few minutes for the phone to start charging. In addition, to fill the capacity of the battery may not be enough power of the charger itself.
Solution: Frog or Power-bank
If the design of the phone allows, you can remove the battery and install it in a special charger “frog”. The device with a non-removable battery is connected to the power-bank.
Suddenly the battery that has been sitting down is a problem that even the owner of a recently purchased mobile may encounter. In 9 cases out of 10, the problem here is due to improper charging of the gadget. If you want your mobile phone to work as long as possible, please read our recommendations in the article.
#2 DEFECTIVE CHARGER
What if the phone does not turn on even when charging? Here the problem can be hidden in the charger itself, namely in its failure or damage.
Solution: The second charger
To check if the charger is in working order, connect the mobile phone to another storage device. If charging has started, you can safely throw out the first charger – it’s exactly broken.
#3 BATTERY MALFUNCTION
On average, the battery in the phones is designed for 2.5 years of operation. If your phone was purchased more than 3 years ago, the battery life may be running out.
Solution: Battery replacement
With a removable battery everything is simple – go to the nearest salon of mobile electronics and buy a new battery. But with a non-removable battery you have to go to the service center.
#4 PROBLEMS WITH CHARGING CONTACTS
Another common reason why the phone does not turn on is the breakdown of the contacts, which is why even a workable battery will not accumulate a charge.
Solution: Diagnose and repair contacts
Check the contacts that are connected to the battery – maybe they have moved a little. In this case, take a thin tweezers and slightly bend the antennae of the contacts. If you have a special screwdriver for electricians, its indicator will show if there are any voltages in the charger connector. Although in a good way, with this problem it is better to contact a professional master.
#5 INFLUENCE OF EXTERNAL TEMPERATURE
Winter and summer are a real test for any touch phone. The fact is that mobile devices do not tolerate high and low temperatures. For example, if you charge the smartphone 100%, and then go with it in a hot and stuffy bus around the city, on the way out you will find that the battery has sat down almost to zero.
Solution: Warm up or cool the phone
Never charge an overheated or supercooled phone. First you need to wait until the temperature of the mobile phone is balanced, and only then put it on charge.
#6 BREAKAGE OF THE POWER BUTTON
A broken start button is also the reason why the phone stopped turning on. Between the button and the contact is a thin rubber or silicone membrane. From constant pressing it eventually wears out and bursts. It can happen after the smartphone falls onto a hard surface.
In this case, we recommend not to risk and carry the gadget for repairs. Membrane repair is not a difficult, fast and not very expensive task.
#7 MEMORY CARD LEVEL MALFUNCTION
The phone can refuse to turn on and because of the SD-card, especially if it was taken from the hands or in an unreliable retail outlet. In this case, there is a high probability that there is a virus on the card that does not allow the phone to turn on. On the other hand, problems can be thrown up by a user-friendly, but crowded card.
Solution: Deleting or formatting
A defective card is better to throw out immediately, regardless of what is on it. And the card, hammered under the string, should be formatted.
#8 INCORRECT SYSTEM UPDATE
Sometimes, users download the update for the operating system from unreliable sources. Such actions can lead to the fact that the mobile device turns into a useless piece of metal.
Solution: return to factory settings
The most obvious way to deal with incorrect firmware is to roll the phone back to the original factory settings. There are three ways to do this:
- Via the gadget menu;
- With the help of service commands;
- In the Recovery menu.
- Go to phone settings
- Click on the “Restore and reset” section.
- Select “Reset settings”.
- Click the button at the bottom of the screen.
After a few seconds, the system will reset its settings, after which it will reboot the smartphone.
Service commands are a specific code that you need to dial on your smartphone’s keyboard. Here are three main combinations:
- * 2767 * 3855 #
- * 7378423
- * 7780 # * #
To enter Recovery Mode, follow these steps:
- Turn off the phone.
- Hold down the Power and Volume keys.
- Select wipe data / factory reset from the list of options.
- Click Yes.
- Wait until the reset is complete and click Reboot System.

#9 TOO LARGE APPLET UPDATES
Almost all applications installed on the phone, especially those connected to the Internet, constantly pump and install large update packages. Such updates often overload the phone.
Solution: uninstall updates
To reset the updates, remove the battery from the phone, put it back in a few minutes, and remove the update packages. How to do it correctly, read in our article How to disable updates on Android.
#10 SMARTPHONE SCREEN MALFUNCTION
The breakdown of the gadget’s screen is an obvious reason, because of which the phone does not turn on, if there are no problems with the firmware and updates. As a rule, the display does not fail immediately. Pay attention to the moments that precede this:
- From time to time, bands appear and disappear on the screen;
- Sharply decreases and the brightness increases, within a few seconds the screen flickers and is restored again;
- The screen on the phone could suddenly “run off” during work or start flickering.
Solution: service repair
If you encounter such problems the problem lies in the cable that connects the screen to the card. Of course, you can try to repair yourself, but without certain technical knowledge, this can lead to a permanent breakdown of the phone.
We recommend that you do not risk your smartphone and better to carry the gadget to a service where specialists will help you to solve the problem.
Now you know what to do if the phone does not turn on. Let’s also give some recommendations that will help extend the life of your gadget:
- Do not repair serious damage yourself
- Try not to secureyoursmartphone from falls
- Do not install applications from untrusted and unknown sources
