LI-ION BATTERY PROBLEMS
My phone is a Samsung Galaxy S4 Active. I bought it as a refurb and it came with two batteries. I shipped one with the old S4 phone when I sold it and kept the original battery from that phone. The battery on the right is that battery. Back in the summer the phone started losing its charge more quickly. So I decided to change the battery. I’m starting to think the problem back then was some app that was updating too often. Everything seemed to be okay until about a month ago. I noticed the phone still plugged in and charging but only showing 97 or 98 percent. Then yesterday the display showed 50% when I walked into a restaurant and after watching a 3 minute YouTube video the phone shut down. I plugged it in when I got to my car and it seemed to recharge faster than normal. Then later, off the charger, the phone dropped rapidly to 60% and shut down. When I got home last night I took the battery out of the phone. I noticed it was swollen. I had heard of this problem with a friend’s iPhone 5S. Customers cannot change the battery in that phone, just as we can’t in the newer Samsung and many other brands. I had the old battery here, so I put it in the phone and charged it. I will probably keep this phone a while longer, so I’ll order another battery in a couple of months and see how it performs.
