How does your day look like? Are you waking up early, checking the news at a morning coffee, the weather as well just to be on the safe side, setting up your navigator to accomplish your daily commute, browsing the internet for some juicy feed, listening music and indulging a calculated amount of entertainment material? Well, it turns out you are using your phone just about like anyone else – a lot.

That is not to say excessively, but our lives have inexorably become intricate enough to demand from us an elevated attention to our phones and their applicability. As you may be using your iPhone 8 for tasks beyond phone calls, the battery takes its toll. So how does it all work?

Firstly, your phone is designed to convey a seamless and fast experience through the intricate combination of advanced technology and complex engineering – the iPhone 8 battery not being an exception. It’s continuous and laborious application, however, induces the battery into a state of regression and galvanic decay. It probably also doesn’t sound unfamiliar that your close smartphonic companion, after a year and a half of faithful servitude, has suddenly started his naughty rebellion with periodic glitches and lags. Nonetheless, don’t be alarmed – all rechargeable batteries have their own lifespan, which, when decreased, significantly affects the performance and capacity of the smartphone. It is simply the life of a battery!

But before jumping into problem resolution, here are a few things you might want to check before changing your battery:

Excessive memory usage

If there are too many applications ravaging your internal memory capacity, clean up the running memory and reduce the strain on your iPhone 8 genuine battery.

Delete/close latent or apps of unknown origin

Sketchy applications of doubtful origins lurk around on the internet, and they can quite often find their way into our device without us even noticing. Latent apps remain in the background while also cocktailing some of the energy of your battery. Delete or close them.

Low Power Mode

You can set your phone on low power mode to reduce its power consumption and let the phone focus on only a subset of applications in parallel.

Screen Brightness

Very often one of the main determinants of battery drainage is iPhone 8 screen brightness. Consumers usually underestimate the amount of battery power it can drain, which is why having a low-brightness screen standard will surely expand the life of your battery.

Now, to the matter at hand. There are three main ways to replace your iPhone 8 battery. The traditional method for iPhone 8 battery replacement is signing up for an Apple Store battery replacement support. You will visit the physical store and the technical specialists will be able will take care of the technical aspects of your repair. However, if the one-year warranty or Apple Care subscription has expired, you will have to pay the cost for technical care.

A second option would be to find a third-party repair shop and entrust your device to their technical professionals. This is more of a gray area and it frankly depends very much on the local circumstances. The third-party repair store might be reputable enough to assume liability for their work and solve your issue, sometimes quicker and cheaper than your typical Apple Store.

If, however, you are looking to feel crafty and your pocket is rather empty, you can attempt to replace the battery by yourself. There are quite a few things to keep in mind, but hopefully this list of steps below will prove sufficient to deal with this challenge head-on:

Step 1:

 Discharge your battery below 25%

 Power off the phone before disassembling

Step 2:

 Unscrew the two pentalobe screws at the bottom edge of your phone

 Heat the lower edge of your phone to loosen up the display adhesives. For this purpose, you can use an iOpener

Step 3:

 Use a suction cup on the lower half of the display (without touching the home button)

 Pull the suction cup upwards to create a small gap between the panel and the case.

 Use an opening pick to slide from the beginning of the gap around the edges of the phone while holding the display in place. Note: Do not pry open the top edge of the display from the case – it is attached by plastic clips that may break upon pressure.

Step 4:

 Open the iPhone 8 lcd by swinging the display up from the left side, like the back cover of a book (Don't try to fully separate the display yet, as several fragile ribbon cables still connect it to the iPhone's logic board.)

Step 5 (battery disconnection):

 Unscrew the four Phillips screws sealing the lower display cable bracket to the logic board and remove the bracket.

 Pry the battery connector out of its socket in the logic board and then tilt its cable slightly away from the logic board.

Step 6:

 Disconnect the display connector from its socket, as well as the second lower display cable.

 Remove the three Phillips screws sealing the bracket over the front panel sensor assembly connector and remove the bracket. Disconnect the panel.

Step 7:

 Remove the display.

 Unscrew the three screws sealing the bracket next to the Taptic Engine and remove it.

 Disconnect the diversity antenna flex cable from the logic board.

 Disconnect the Wi-Fi diversity antenna.

Step 8:

 Remove the screws sealing the Taptic Engine, move away the antenna cable socket, and disconnect the Taptic Engine

Step 9:

 Finally, the two pieces of adhesive attached to both the top and bottom part of the battery must be slowly pulled away from the battery until it slips out from between the battery and the case.

After following these steps, you should be now able to do an iPhone 8 battery replacement and reassemble your phone back. The process might seem long and tedious, but it is worth the try and not an ordeal as it might first seem. And now, have fun with your upgraded device!

Catastrophic failures of lithium-ion batteries are rare. When they do occur though, the consequences can be quite serious. There have been past reports of serious injuries and deaths resulting from exploding cell phone and e-cigarette batteries, for example. As such, anything we can do to make lithium-ion batteries safer should be done.

A group of researchers in Germany think they have come up with something. They have devised a non-contact way of measuring the charge state of a battery using magnetic fields. They say their method can also be used to detect potential problems that battery makers would otherwise be unaware of.

How Batteries Work

All batteries rely on a cathode and anode (the positive and negative ends of the battery) to store and transfer energy by way of a chemical reaction. In short, the chemical reaction inside a battery case increases the volume of electrons at the cathode (positive end). When the circuit is completed at the anode (negative end) power is transferred from the battery to the device it powers.

The German researchers surmised that normal battery activity might disrupt surrounding magnetic fields. So, they turned to something known as a magnetometer to see if they were right. It turns out they were.

Magnetometers are routinely used by theoretical physicists in their search for the origins of the universe. The devices are also used in a variety of commercial and scientific applications to measure magnetic fields. So, we are talking about a fairly common device.

What They Did

To test their theory, the researchers created a magnetic field into which they place lithium-ion batteries. They then used a standard magnetometer to measure the strength of the magnetic field and any displacement caused by the batteries. They discovered that the amount of displacement was relative to the charge state of the battery being measured.

Using a magnetometer allows for a non-contact means of determining charge level. It also allows for observing other properties of the surrounding magnetic field that would indicate a particular battery is faulty. Battery faults are not so easily observed through current non-contact means.

Why It Matters

To understand why any of this matters, we turn to Salt Lake City's Pale Blue Earth, an up-and-coming company that specializes in lithium-ion USB rechargeable batteries. The good folks at Pale Blue Earth explain that a non-contact way of measuring battery state could help manufacturers find faulty batteries before they make it into the pipeline.

If that is true for Pale Blue Earth batteries, it should also hold true for cell phone, laptop, and camera batteries. It should hold true for any lithium-ion battery that can be safely placed into a magnetic field.

Imagine being able to measure batteries before they are put on a plane and shipped across the country. Identifying faulty batteries ahead of time would greatly reduce the risks of catastrophic failure in flight. And that is just one example of the implications of this discovery.

Daily Applications

In a more practical vein, the discovery opens the door to developing consumer solutions that would allow everyday users to better measure how much juice is left in their batteries. Such a solution would allow a runner, for example, to make sure her lithium-ion batteries are fully charged before she heads out on a run with her portable MP3 player.

Measuring battery charge state with a magnetometer is so remarkably simple it's a wonder no one thought of it before. But now that researchers have discovered it works, the doors open to all sorts of scientific and daily applications. If nothing else, the discovery could make lithium-ion batteries safer.
