Chosen Solution

For the last year or so, my tablet would spontaneously reboot unless I kept it plugged in all the time. However, for the last two weeks, even when plugged in, it will spontaneously reboot every minute or so. I’ve read about how the battery connection probably needs to be soldered, but how do I do that? I assume I need to purchase a soldering gun , etc. Perhaps it’s cheaper to get a replacement, but won’t the replacement do the same thing? Are the refurbished tablets soldered already to prevent this problem?

I just replaced the battery using the steps this site provided here. Excellent! My tablet works great now! No more rebooting! The micro USB charging port looks to be soldered in, meaning i will have to take the time later and use the soldering gun to remove it? The back still warms up, but after a lot of reading, it appears it is the CPU and i am using an app from google play called “Phone Cooler Master” its a fan with a red dot in the middle of it. It works well to lower the CPU usage and cools my tablet. Samsung Galaxy Tab A 8.0 Repair
