Ok, it’s technically not an apple in the most real sense of the word. God or Eve or even the devil had little influence on this fruit. We are talking about an iPhone.
Let my experience with this device be a cost-saving measure for you.
With the lockdowns and subsequent lack of leaving the house, the phone, which usually lives on my person, hardly ever left the desk.
Since it never left the desk, it also never or hardly ever left the charger.
The physics that goes along with these batteries is somewhat elusive, but batteries are designed to be used. Said another way, unlike car batteries, these batteries in your laptop, cell phone, and tablets are designed to cycle on a larger scale than your car.
They are rated in how many times they can be ‘cycled.’
On my desk laid the iPhone plugged up to a constant source of energy. Monitoring the current from the power supply to the phone, I noticed no appreciable current draw but, something was happening.
Simultaneous events occurred during February and March. The phone seemed to split apart. Something inside the phone was expanding. It could only be the battery. Knowing that these batteries can be volatile, a new phone seemed to be in order. Repairing an old phone makes little sense by the time you find a place to take it and so on.
Another thousand dollar phone later seemed to be the right approach. Trying to leave the house presented a whole new challenge. The car battery was dead.
With all the electronic ‘stuff’ in cars today, there is about a 250 ma constant draw on the battery. If you don’t drive it weekly, put a trickle charger on the battery.
Here we juxtapose the two different technologies. Lead Acid batteries are designed to give you that current with a small amount of discharge in the process of starting the engine. Once started, the alternator puts the energy consumed, back into the battery. Hence one cycle is complete.
In Texas, anything over three years is considered a win. Heat is detrimental to lead-acid batteries.
Switch gears to the phone. The Lithium Polymer battery will provide the correct voltage and current until depleted. Translated, if you puncture a phone battery while trying to remove it while still charged, it very well might combust into flames.
The battery in my older iPhone expanded much like a balloon while living on my desk. Not having taken one of these phones apart before, I felt the proper thing to do would be to recycle it and forget it. (but It still worked.)
The longer it sat there with its screen popping off, and the more time I had to think about it, google became the go-to source of information.
$22 later, I had a new battery and the tools to change it on the way to my home.
While the procedure is not for the faint of heart, if you were to follow the directions to the letter, the odds are, you too could save your phone.
The older phone still provides a platform for Zoom, music, and yes videos. The newer phone now lives on an inductive charger, which, according to the manufacturer, will not overcharge your battery.
Since the older phone is repaired and looks great, I unplug it from the charger as I use it like one usually would. Even without actual ATT service, with wifi, there are many ways to use the phone as a phone still.
The trickiest part of the procedure is removing the old battery. It is glued to the phone. This is where you could create an explosive situation if you are not super careful. One tip I would offer is, drain the battery completely before you attempt a procedure like this.
How? Turn the phone on and listen to music until it is dead.
Regarding your car, make sure the trickle charger is rated at least an amp. The trickle charger I bought from one of those box stores used a little wall wart as the supply. It did not provide sufficient current to keep the battery charged and run whatever stand-by devices were drawing minuscule amounts of energy.
I now use a zero-point charger that shuts off when the power drain falls below a few milliamps. As the devices draw enough current to trigger the charger, a cycle is developed, keeping the car ready for when you need to escape from quarantine.
I hope you find this information of some value and that you stay safe during these trying times.
