Samsung Galaxy Note 4 Won’t Stay On Issue & Other Related Problems

One of the main strengths of the #Samsung Galaxy #Note4 is its battery life. This 5.7 inch smartphone uses a 3220 mAh battery which is enough to last more than a day of normal usage. Once the battery life is low all you need is to recharge the phone using a wall charger otherwise the phone will turn off.

Note 4 Won’t Stay On

Problem: My phone is constantly power cycling and won’t stay on.  When the phone is plugged in it will, sometimes, stay on and I can use the phone.  To add a twist, the phone did stay on one time during this, until I attempted to use the camera and it went back to power cycling again…I have followed all listed troubleshooting item listed…and they do not fix this problem…can you help?

Solution: I’m assuming that you did the troubleshooting steps up to the factory reset. If the problem still occurs then it could already be hardware related. Try to check if your phone battery is causing this problem by replacing it with a new one. Sometimes if a battery is not supplying the correct voltage then the phone may turn off.

If the problem persists then I suggest bring your phone to an authorized service center and have it repaired.

Note 4 Restarts When Battery Level Is Low

Problem: 2 months ago or so my phone started shutting restarting once it got to 34% then it would completely die. It kept doing that and even at 54% it starting shutting off on its own if I was using an app like lyft or snapchat. Today, it was at 80 something and when I tried to charge it, the battery bar on the screen pops up and goes black. It just keeps repeating until I unplug the charger.

Solution: The first thing you need to do is to determine if this problem is caused by an issue with the phone software. To do this you will need to backup your phone data then do a factory reset. Once the reset is done do not install any apps just yet. Observe your phone first if the problem still occurs. If it does then try getting a new battery as the battery you are using may already be defective.

If the issue still occurs even if your phone is already using a new battery and you already performed a factory reset then this could already be a hardware related problem. If this is the case then I suggest you bring your phone to an authorized service center and have it checked.

Note 4 Only Turns On When Plugged To Charger

Problem: Note 4 restarts when being used, when it gets to the SAMSUNG GALAXY NOTE 4 screen it’ll restart again, it’ll only turn on if I plug it into the charger. It only happen when I start using the phone. I did a factory reset already and problem still persist

Solution: It looks like this problem is caused by a faulty phone battery. The phone is able to detect the voltage being supplied by the battery. If the voltage decreases below the minimum working value then the phone could shut down on its own. One other factor that makes me believe that the battery is causing this problem is that the issue disappears when the phone is connected to its charger. Try to replace the battery with a new one then see if the issue still occurs.

Note 4 Not Recognizing Charger

Problem: Note 4 does not reliably recognize and connect to external power. Cleaning connectors, changing battery and charger, resets, do not affect this.

Solution: It appears that you already performed most of the troubleshooting steps needed to resolve this type of problem. Have you tried using a different USB cord? If you have then the problem may be with the power IC of the phone. I suggest you bring your phone to an authorized service center and have it checked.

Note 4 Not Charging With Fast Charger

Problem: My note 4 is note charging from any fast adapter but it charges as A/C current charge with non fast charging adapter.My fast adapter works fine with other note 4 mobiles.

Solution: Have you checked if the fast charging mode setting of your phone is enabled?  To do this go to Settings > General. Tap on Battery then check “Fast charging”.

If fast charging has already been enabled then try to replace the charging cord that you are using. This cord gets easily damaged especially if it is constantly coiled or bent and can prevent the device from fast charging.

You should also check the charger port of your phone for any signs of dirt or debris. If necessary clean this port using a can of compressed air or cotton bud dipped in alcohol.

One other factor that can prevent the phone from fast charging is a glitch in the phone software. If this is the case then you should backup your phone data then do a factory reset.

Note 4 Battery Drains Extremely Fast

Problem: Battery drains on my wife’s phone extremely fast. Sometimes it drains from a full charge to dead in a matter of minutes or an hour. Having trouble getting most recent update from carrier. It starts upgrade and fails and says upgrade is interrupted. Can you help?

Solution: There are two possible reasons why your phone drains extremely fast. First, it could be caused by the phone software. A rogue app running in the background, corrupt temporary data, or an unnecessary process that is running can cause this problem. If this is the case then you should start the troubleshooting by checking the battery statistics of your phone and see what is using the most battery life. If it is an app then you can try to uninstall it. If it is a media related process then your phone microSD could be faulty. If the card is faulty your phone will have a hard time getting data stored in the card which will drain your battery. Try removing the microSD card if this is the case.

If the problem is caused by some form of corrupt data then I suggest you start your phone in recovery mode then wipe its cache partition. If this fails to resolve the issue then I suggest you backup your phone data and do a factory reset.

The second possible reason why your phone battery drains quickly is if the battery itself is faulty. If this is the case then try to get a new battery then check if the issue still occurs.

As for the software upgrade issue this will be most likely resolved after the factory reset. If the problem persists then upgrade your phone software using Kies or Smart Switch.
