Common iPhone 7 Plus Problems & Solutions

Alright, let's get down to business. What are the most common issues that plague the iPhone 7 Plus, and what can you do about them? We'll break it down into the most frequent culprits and offer actionable solutions. Remember, before you start any repair, always back up your data. Seriously, data loss is the worst. Back it up to iCloud or your computer. Okay, now that we've got that covered, let's move on to the problems.

Cracked Screen

A cracked screen is probably the most common ailment. You drop your phone, and bam! Suddenly, you have a spiderweb of cracks staring back at you. First things first: assess the damage. Is it just a few hairline cracks, or is the screen completely shattered? Depending on the severity, you might still be able to use the phone, but the touchscreen functionality could be affected. Replacing the screen is often the best solution. You can either take it to a professional repair shop (make sure they are reputable, read reviews!), or you can DIY. DIY screen replacements are possible but require some technical skills, patience, and the right tools. You'll need a new screen, a set of iPhone repair tools (including a pentalobe screwdriver, suction cup, and spudger), and a guide. iFixit is a fantastic resource with detailed guides and videos. When replacing the screen, be extra careful with the home button flex cable. It's delicate, and damage to it can render your home button useless. Also, remember to transfer the earpiece speaker and front-facing camera assembly to the new screen. They are important for calls and Face ID. Always disconnect the battery before you start working on any internal components. This prevents any accidental shorts. If you're not comfortable doing this yourself, definitely seek professional help. The peace of mind is worth it!

Battery Drain

Is your iPhone 7 Plus battery draining faster than usual? This is another biggie. There are several reasons why this might be happening. The most obvious is an aging battery. Batteries degrade over time, and they eventually lose their ability to hold a charge. If your phone is more than a couple of years old, this is likely the culprit. Other factors include: Using power-hungry apps (like games or video streaming apps), keeping your screen brightness too high, or having location services constantly running. To diagnose the problem, start by checking your battery health in Settings > Battery > Battery Health. If the maximum capacity is below 80%, it's time for a replacement. Even if the battery health is good, try reducing screen brightness, disabling background app refresh, and turning off location services for apps that don't need it. Close apps that you aren't using. If you have done these things and the problem persists, a new battery will probably do the trick. Battery replacements are generally easier than screen replacements, but you'll still need the right tools and a little bit of know-how. Or, if you prefer the easy way, visit a professional repair shop. They can replace the battery quickly and efficiently.

Not Charging

Your iPhone 7 Plus won't charge? This could be a frustrating problem. The charging port could be full of lint and debris. This is a very common issue. The lightning port can easily accumulate dust and pocket lint, preventing a good connection. Grab a toothpick or a small plastic tool (avoid using metal objects) and carefully clean out the port. Be gentle! You don't want to damage the pins inside. Try a different charging cable and power adapter. Sometimes the cable or the adapter is the issue, not the phone itself. Try charging from a wall outlet instead of your computer. Wall outlets provide more power. Check the charging port for corrosion. If you see any green or white buildup, that could indicate water damage. In this case, you'll need to seek professional help. If you have cleaned the port, tried different cables and adapters, and the phone still won't charge, the charging port itself may need replacing. This is a more complex repair that requires soldering, so it's generally best left to professionals. Before assuming the worst, though, try a hard reset (press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the power button until the Apple logo appears). This can sometimes resolve software glitches that prevent charging.

No Sound

No sound from your iPhone 7 Plus? This is a bummer, whether it's the earpiece, the speakers, or both. Check the volume levels. Make sure the volume isn't muted or turned down all the way. Check the mute switch (the physical switch on the side of the phone). If it's on mute, you won't hear any sound. Clean the speakers and earpiece. Dust and debris can block the sound. Use a soft brush or compressed air to clean them out. Check the audio output settings. Make sure your phone isn't connected to a Bluetooth device or AirPlay. If it is, the sound will be routed to the connected device instead of your phone's speakers. Try a hard reset. Sometimes a software glitch can cause audio issues. If the issue persists, the problem could be with the speakers or the audio IC (integrated circuit) on the logic board. Speaker replacement is a relatively straightforward repair. Audio IC repairs are very complex and often require micro-soldering. In this case, professional help is required.

Wi-Fi Issues

Having trouble with Wi-Fi? Check your Wi-Fi settings. Make sure Wi-Fi is turned on, and that you're connected to the correct network. Check the signal strength. If the signal is weak, you may experience connection issues. Try restarting your phone and your router. Restarting these devices can sometimes fix Wi-Fi problems. Reset your network settings. Go to Settings > General > Reset > Reset Network Settings. This will reset your Wi-Fi, Bluetooth, and cellular settings. You will need to re-enter your Wi-Fi passwords. The Wi-Fi antenna could be damaged. If you've dropped your phone or it's been exposed to water, the Wi-Fi antenna could be damaged. Wi-Fi antenna replacement is a moderate-level repair. In some cases, Wi-Fi issues can be caused by problems with the logic board. Logic board repairs are very complex and should be left to professionals.

Okay, let's zoom in on the specific model RA 2737901i N259M. Why is knowing your exact model important? Because, as mentioned earlier, there can be subtle differences between different iPhone 7 Plus models, even those that look identical. These differences can affect the parts you need for a repair.

You can find your IMEI number in Settings > General > About. The IMEI can be helpful for identifying your phone's specifications, checking its warranty status, and checking if your phone has been reported as lost or stolen. The IMEI is useful if you need to contact your carrier or Apple support. If you are ordering a replacement screen, or battery, or any other component, look for parts that specifically state that they are compatible with this particular model. If you are unsure, contact a reputable repair shop and ask for their advice. They will be able to help you. Always be careful. When in doubt, seek professional advice.

iPhone 7 Plus Repair: DIY or Professional?

So, you've identified the problem, and now you have to decide: DIY or professional repair? This is a crucial decision, and the right answer depends on several factors. Let's break it down.

DIY Repair Advantages:

  • Cost Savings: Repairing your phone yourself can save you money. Parts are often cheaper than professional labor. This is especially true for simpler repairs like screen replacement or battery replacement.

DIY Repair Disadvantages:

  • Risk of Damage: If you're not careful, you could make the problem worse, or damage other components. Static electricity can damage sensitive components.
  • Time Commitment: Repairs can take time, especially if you're new to the process. You'll need to research the repair, order parts, and follow instructions. Expect to spend hours working on your phone.
  • Tools and Expertise: You'll need the right tools (screwdrivers, spudgers, suction cups, etc.) and a good understanding of how the phone works. Repairing the internal components will require special tools and experience.

Professional Repair Advantages:

  • Expertise: Professionals have experience and specialized tools. They know what they're doing. They can diagnose the problem quickly and efficiently.
  • Warranty: Most repair shops offer a warranty on their work. If the problem persists or reoccurs, they will fix it for free. This gives you peace of mind.

Ultimately, the best choice depends on your comfort level, your budget, and the severity of the problem. If you're comfortable with electronics and the repair isn't too complex, DIY might be a good option. However, if you're not comfortable or if the repair is complex, it's best to go with a professional. The professional knows what they are doing. Either way, always back up your data!
