Open the iPhone and have a brand charger port at hand
Every week we get roughly a dozen customers coming into our store asking if we fix an iPhone 7 Plus that is not charging. In most cases the iPhone 7 Plus is a simple fix and can be diagnosed using a simple guide online. Whereas other methods, such as a faulty Charger IC or no sound problem due to a fualty Audio IC, and require a trained technician to fix the problem. In this article, we'll show you the steps you should take to help you determine why your iPhone 7 Plus isn't charging and give you actions you should consider fixing your iPhone 7 Plus for good.

In most instances no. The battery doesn't affect the charging capabilities of an iPhone. In fact, as a phone technician, the battery is one of the last things we try in troubleshooting an iPhone 7 Plus that turns on and isn't charging. Our reasoning being that the battery doesn't control the phones charging capabilities. Testing the battery first on an iPhone 7 Plus is relevant when a phone doesn't turn on.
It's the middle of the night. You're getting tired so you begin get ready to go to bed and you notice the iPhone is at 15% battery life. You plugin a charger to the iPhone but it doesn't show the usual lighting symbol you get when its charging. You wiggle the charger searching for the right angle to charge your iPhone. You think you found it. The iPhone is now charging but you continue to feel some resistance when inserting the charger. In the morning you reach out to get your iPhone and you see that the battery is down to 10%. But why?
In 2017 we published an in-depth article addressing this issue on iPhone's not charging properly due to lint or dirt inside the charger port. With confidence I can safely say that seven out of ten customers have this issue and this method is still relevant in 2019.
If the word "wiggle" comes to mind when plugging in your lighting cable then lint may be the cause of your charging headaches. At our cell phone repair store we use the word "wiggle" as a keyword to help us diagnose this charging issue that is common with iPhone's.
As shown in the image above, you can see that the lighting cable is not inserting properly. This is the best indication that your iPhone 7 Plus is not charging due to dirt or lint inside the charging port. If this is the case with your iPhone 7 Plus then all you need is some tweezers to clean the lint from your iPhone and some patience.
The video below shows you exactly our method to safely removing lint.

When you purchase a brand new iPhone, inside the box includes a brand new USB lighting cable and wall charger.
Aside from lint, even though less common, a defective USB lighting cable or wall charger can be another reason why the iPhone 7 Plus can experience charging difficulties. After our lint/dirt inspection fails, the next thing we check is the USB lighting cable.
We've had plenty of customers stating that they've tried multiple USB chargers but the phone still didn't charge. We've also seen the shocked in a customers face when their iPhone began to charge with our lighting cable. In this instance we advise them to check the USB lighting cable and wall charger hub. Chances are that one, if not both of the components are defective.
Inspecting lighting cable
A damaged lighting cable is a common reason an iPhone can experience charging issues. This lightning cable is a multi-purpose cable that can be connected with wall chargers, used to transfer data between a iPhone and computer, and can be connected to a car charger.
This means that users are constantly removing the lightning cable instead of leaving it at one location. Constantly unplugging the lighting cable can put a strain on the cable and cause the connections inside the cable to be stretched over time.
My suggestion to inspecting a USB lighting cable are the following:
Inspecting USB Wall Charger Hub
The method we use to inspect the USB wall charger hub is pretty similar to what we talked about with the lighting cable.
Apple is constantly releasing new software. Occasionally these software updates get released with bugs. Even though it's very rare, software updates can occasionally cause a software bug that prevents the iPhone from receiving power.
To test the validity of a software bug causing a iPhone 7 Plus to experience charging difficulties we recommend to first try a hard reset and if that doesn't work then you can also do a factory data reset. A factory data reset should be done as a last resort and damaged components can prevent your iPhone 7 Plus from completing the factory reset. We recommend you backup the data before a conducting a factory data reset.
If you've made this far into the article, then that probably means I have failed you. Your iPhone 7 Plus is still not charging and will require you to take it to a professional. My goal now is to equip you with knowledge on hardware failures that can prevent your iPhone from not charging and give you a few recommendations on fixing your iPhone 7 Plus.
Testing these hardware issues may be a bit difficult to diagnose especially without the proper tools and knowledge. My goal here isn't to show you how to repair your iPhone yourself but explain the steps we take diagnose an iPhone 7 Plus that isn't charging. These repairs are difficult to do by yourself because the motherboard needs to be removed completely repair either issue.
Diagnosing a Damaged iPhone 7 Plus Charger Port
A diagnosis can be done without installing the entire charger port. We will show down below our method.
Open the iPhone and have a brand charger port at hand
Connect the new charger port and try it with the lighting cable
Give it up to 30 minutes and wait to see if the Apple logo appears
Once we see the Apple logo, we conclude that the charger port was the one malfunctioning and would need to be replaced. The charger port replacement requires the technician and can take up to two hours.
If the logo never appears then we attach a brand new battery to check if the iPhone charges with a brand new battery. It's possible that the battery may have malfunctioned. If iPhone continues to show no sign of it charging then we conclude that the Charger IC U4001 chip set has malfunctioned.
