Solved Samsung Galaxy S8 Charger Disconnects Reconnects Rapidly

The #Samsung #Galaxy #S8 is a flagship phone released last year that sports a new design that is a departure from the previous flagship model of the company. This new model uses a much larger 5.8 inch Super AMOLED display with very minimal bezels. It does not have a fingerprint sensor or physical home button at the front instead the sensor is located at the back of the device. Although this is a solid performing phone there are instances when certain issues can occur which we will be addressing today. In this latest installment of our troubleshooting series we will tackle the Galaxy S8 charger disconnects reconnects rapidly issue and other related problems.

S8 Charger Disconnects Reconnects Rapidly

Problem: Just bought an adaptive fast charger for my Galaxy S8. It seems like it works but it keeps restarting charging several times as if I kept on re-plugging the charger into the wall outlet.  Can you help me solve this issue?

Solution: In most cases this issue is usually caused by the phone and charger not having a good connection. To fix this you need to follow the troubleshooting steps listed below.

  • Clean the charging port of the phone using a can of compressed air making sure that any dirt or debris stuck in this port is removed. Check if the issue still occurs.
  • Try using a different charging cord to charge the phone. Sometimes this issue can be caused by the cord that you are using especially if it has some loose wires or if it does not fit properly to the charging port of the phone.
  • Try using a different wall charger.

In case the issue persists at this point then you will have to bring the phone to a service center and have it checked as the problem could be caused by a faulty charging port.

S8 Not Powering Up

Problem: My S8 isn’t powering up when using the button the only way I can tell it still kind of works is when put on a wireless charger and the recent apps and back button lights up. Volume buttons work too as I can hear the beep every time I adjust my ringtone volume.The led light comes on occasionally in blue to indicate I have notifications. AND DO NOT TELL ME TO GO INTO SAFE MODE RECOVERY MODE OR ANYTHING. I CANT EVEN TURN IT OFF. i forced restart it and did not see any samsung logo. I’m guessing it’s the lcd screen malfunctioning?

Solution: Try charging the phone first for 30 minutes using the wireless charger. Once this is done check if you are able to start the phone in recovery mode. In case you can access this mode then you should do a factory reset from here. Take note that the reset will erase your phone data.

In case the issue persists then this is most likely caused by a faulty hardware component possibly the display assembly. You will need to bring the phone to a service center and have it checked.

S8 Incorrect Battery Level

Problem: Hi. I recently rooted my phone, hoping to take advantage of what I’ve learned about lithium-ion batteries and install a program called Battery Charge Limit which allows the user, with compatible phones, to custom set the threshold for charging, so the user can leave their phone on the charger without it actually charging to full. This, from what I’ve gathered, if essential to increasing the longevity/lifespan of these type of batteries. You can, for example, tell the program that you want it to charge the phone when it gets below 25% and charge only to 60%. After struggling to root the phone (to allow usage of this program) and finally succeeding, I installed the program and discovered, much to my dismay, that although it would initially stop charging at the limit I had set, after several minutes it would continue charging. Around this time I also started keeping an eye on the charge voltage and realized that although Battery Charge Limit would say that it was in DISCHARGE mode, it was actually charging as the voltage continued to climb. Long story short, after experimenting with different settings for about a week, I finally gave up on the program and uninstalled it. Since then, I just keep an eye on the charge voltage through a Battery Status page . Here’s the rub. I’ll unplug the charge when the voltage gets around 3.92 volts, but the battery gauge/meter often has not risen to reflect actual state of charge. Let’s say I start at night, before bed, with the phone at 50% and 3.92 volts charging. I unplug the charger and turn off the phone after closing all open apps and clearing all the Cache junk with Security Master, an installed app and PowerPro, another app I use. By morning the battery gauge is in the low 30s even though the voltage is still pretty high. Maybe 3.8 volts. Pretty soon I get warned by the phone that the charge is getting low (15%, I think) and even though I can charge it back to 3.92 volts, I can’t get the gauge to register much higher than 30%. The only solution I’ve found is to turn off the phone and boot up after several minutes. Then, sometimes, the counter will go back to somewhere in the 40s. What’s going on? Do I have to use the phone until it shuts off and recharge FULLY to get the gauge working correctly again (something I’m hoping to avoid because this practice is harmful, from what I’ve read, to lithium-ion batteries)? Is this problem related to rooting the phone, and, if so, should I unroot it? I can’t find mention of this problem with this model on the internet, but perhaps it is/was a widespread problem that was solved by a software patch or update that I haven’t gotten because my phone is unlocked and no longer tied to a carrier (it is a branded T-Mobile).  I’ve tried wiping the cache partition in Recovery Mode, but this doesn’t help. Only restarting seems to provide a temporary solution. Many thanks for any input you can provide.

Solution: The best thing that you can do right now is to check if this issue is caused by some software glitch by doing a factory reset. Make sure to backup your phone data before doing the reset. Once the reset is complete do not install any apps in your phone. Try checking first if the issue still occurs. If it does then the battery might already be faulty. You will need to have this checked and if found to be defective have it replaced at a service center.
