WHAT A BAD BATTERY CAN DO TO YOUR BELOVED IPHONE
Okay folks, pay attention closely if you own an iPhone 5, 5C, or 5S. The life of your phone could depend on it.
Tonight, I had the pleasure of fixing a gentleman's iPhone 5 that had a situation where the screen was popping up. Plus, when pressing your finger on the front glass, you could see discoloration on the LCD in a vertical area.
At first, I thought he just had a defective screen assembly where the glass separates from the plastic and metal brackets. But the owner also told me that he had a bad battery, and believed it was bulging and forcing the display out from the metal phone frame.
I asked him if the battery was doing strange things, like discharging rapidly, or charging erratically. He said no, the charge was doing fine, but it was only the problem of battery bulge. I wouldn't have believed it until I saw it.
Just as you seen the in picture, his phone was coming apart on the top end of the screen, which made it extremely difficult for me to remove the LCD assembly from the metal frame. It took quite a while for me to carefully pry up the screen without permanently damaging the LCD.
I told him that it was a 50/50 shot at getting this screen removed and having it go back in without any problems, but we decided to trudge forward. After much to do, I successfully got the screen removed from the frame.
Lo and behold, the battery inside the phone was bulging, just as he described. What causes this to happen is that the layers of lithium inside the battery that are separated by a thin film find a way to short circuit, thus making the battery bulge.
The battery bulging will force the screen assembly out of the frame, and could end up in permanent damage to the LCD. But worse than that, the battery can bulge to the point that it eventually explodes, or in rare cases, catches on fire.
I learned a good lesson on just how dangerous dealing with lithium ion iPhone batteries can be a couple of years ago when I hastily removed an iPhone 4S battery from a frame. Using a metal spudger, I forced the battery out quickly, causing it to bend. That bending caused the thin layers of insulation between the lithium layers to break down, short-circuiting the battery.
I grabbed the battery with my fingers to pry it out after bending it with the spudger, and noticed an acutely painful sensation in my finger. After I snatched my hand away from the battery, a small orange ember appeared, and then a flame shot out from the battery.
Keeping my burned finger in a bowl of ice half the night to cool the barbecue sensation taught me a fine lesson about respecting lithium batteries, and how dangerous they can be. That's why I knew to be super careful when I removed the screen from this iPhone 5 only to discover a bulged battery that needed to come out.
The Apple Corporation did a massive recall on the iPhone 5 for defective batteries. But they left half the defective phones out in the wild, denying a great percentage of people a repair covered under warranty. So they are still out there.
If you notice your screen popping up, know that this is a potentially serious issue that you should have checked out immediately. And don't try to remedy it yourself unless you are willing to potentially tear up your phone, burn your fingers, have your battery explode.
My advice? Leave it up to the experts, and get it fixed as soon as you notice the symptoms!
