The phone won’t start to boot at all and the screen remains black
The most common issue with the phone not able to even start would be a battery that isn’t charged, try plugging in the charger firmly, ensuring that there’s no obstructions in the port and letting the phone build a charge for a while.
If the device still won’t turn on after charging the problem may be a dead battery, or a cord that can no longer carry a charge. The manufacturer can sell both a new battery or replacement charger. Remember to try another power outlet when charging as you may have a dead socket.
Battery life is determined by many variables. Age is one of the biggest factors, but in considering age you are considering average use and average charge cycles.
Usually there will be specification on the average charge cycles of most batteries. But at the end of the day this information is irrelevant to the user because nobody remembers how many times it has died and recharged. The best thing to do is look out for these major indicators:
• Is the battery not getting a full charge, even after it has been plugged in all night?
• Is the battery icon giving you false readings? I.e. says 100% then 20 min later says 70%?
• Not holding a charge at all?
• Battery is swollen, meaning has an irregular shape/roundedness to it?
All of these are common issues seen by these devices. This is common in most every battery.
If you have answered yes to any of the above questions then you stand a good chance that you need a new battery.
Sometimes after the phone turns off improperly it has a difficult time restarting, try using the device recovery steps to reboot the phone correctly by.
Hold down both the Volume Up, Volume Down, and Power buttons for 30 seconds or until you see the android lying on his back with his belly open. This is the bootloader. Use the volume keys to navigate to “Power off,” and touch the power key. Trying powering up normally.
If it worked when you plug in your phone you should see indication of it charging.
If the above steps didn’t work, another option is to wipe data to reset to factory settings (which means you would lose all your data currently on the phone!)
Once again hold down the Volume Up, Volume Down, and Power buttons for 30 seconds until the android icon appears. Using the volume up and down buttons navigate to “Recovery mode,” and press the Power button. The Google logo appears, followed by an Android with a red exclamation mark. Hold the Power button down and click the Volume Up button to enter Recovery. Use the volume buttons to highlight “Wipe data/Factory reset” and click the Power button.
