iPhone not charging when plugged in? 

Once you're certain that it's not an issue with the outlet, charging block or cord— and the phone still isn't charging, then the problem can be reduced down to a few different options: a bad battery, charging port, or tristar. 

Any knowledgable electronics repair shop should be able to pretty quickly determine the source of the issue by observing if the phone draws any current with an ammeter, dryfitting a new charging port and new battery, and observing the response through the ammeter. 

A bad tristar might still result in the phone drawing current, but won't allow the battery to charge. To be certain, a known working battery might be dryfit onto the phone and if the phone still won't charge the new battery, then a tristar repair is indicated.

 

So what is a tristar?

A tristar is a chip (1610A3) on the motherboard that recognizes if the phone is plugged in, and addtionally determines if the battery is safe to charge or not. The tristar interfaces with the baseband and functionality of the chip can be definitely tested by using a digital multimeter on the battery terminal to see what voltage the terminal is carrying when the phone is plugged in. With a working tristar, the terminal might be carrying 3.6-4.2v, but a bad tristar will be indicated by 2v or less at the terminal.

What causes a tristar to go bad?

Typically, charging your iPhone using a third party charger or lightning cable that is not Apple MFI certified allows for larger variables in voltage and current, this then damages the tristar chip and can leave you with a seemingly dead/not charging iPhone. Lightning cables actually have a chip in them that regulate the voltage and current being pushed through into the charging port.

Another common reason for this is also charging your iPhone from the cigarette lighter of your car. This does not regulate the voltage as well as the original AC adapter, since alternatively the power is coming from the alternator. If you need to charge your iPhone or any electrical equipment in your car we would recommend a good quality inverter with your original charger and Apple lightning cable.

iPhone battery symbol not charging

 Plauged with an iPhone 5, iPhone 6, or 6S that does not charge even after a battery replacement and/or a new charger port install?

 

This may be the result of a charging ic on the motherboard typically referred to as the U2 or tristar.

This issue is normally caused by using cheaper third party charger that does not regulate the voltage and as such spikes in the voltage will ruin the charging integrated circuit.

 

Charging your iPhone using a third party charger or USB lead that does not regulate this as much allows for larger variables in voltage and current, this then damages the U2 IC and can leave you with a seemingly dead iPhone. Another common reason for this is also charging your iPhone from the cigarette lighter of your car. This does not regulate the voltage as well as the original AC adapter as the power is coming from the alternator. If you need to charge our iPhone or any electrical equipment in your car we would recommend a good quality inverter with your original charger and USB lead.

 

Having a phone that won’t charge or turn on is one thing, but knowing that there’s a chip inside that’s damaged and preventing it from turning on is an entirely different frustration. But, knowing is half the battle, both when it comes to the cables being used and the steps needed to fix it. Did you ever suffer from an iPhone  that wouldn’t turn on, or charge over 1%?

How to fix iPhone battery shutting off in cold

Do you have an iPhone that battery randomly shuts off in the cold?

 

 

 

  • This is a common problem faced by many users with batteries in the colder climates.

 

The iPhone Battery

All iPhones use a type of battery called Lithium-Ion (sometimes abbreviated Li-ion). This is the most common battery technology found in rechargeable devices.

Li-ion batteries carry certain advantages – they charge fairly quickly and don’t need to be completely depleted before recharging (in fact, it’s better to recharge at 20% then waiting for your phone to die). Unfortunately, these batteries don’t do so well when the temperature outside drops.

 

Lithium-Ion batteries suffer in extreme cold temperatures:

According to Battery University, cold temperature “increases the internal resistance and diminishes the capacity” of a Li-ion battery. Specifically, they estimate that at -18 degrees Celcius a Li-ion may only deliver 50% of its capacity.

During last winter’s Polar Vortex, Global news did an experiment which showed an iPhone left outside dropped 14% in only 30 minutes, while an identical phone left inside dropped only 1%.

 

 

 

Apple specifies that their batteries work best at a range of 0 degrees Celsius to 35 degrees Celsius. While we almost never reach the upper range in Canada, temperatures below freezing are typical for the winer months.

 Because the battery meter is calibrated assuming warmer temperatures, the reduced capacity in the cold can cause the reading to be unreliable. This is one of the reasons your phone may die while still showing 30%.

 

All cell phones use Lithium-Ion batteries and as such as subject to this problem. This issue is also exacerbated when the battery itself has been used for a great deal of time (>1yr) and is already week due to the high cycle counts incurred from multiple charges.

 

The best thing to do when the battery is older is to get it replaced which is a quick and easy repair provided by the technicans working at Wires Computing. Most battery replacements for iphones and other devices are less than $65 and take only about 15-20mins to replace and test.
