On some iPhone models a swollen battery may expand and break the back cover or even the screen.

When replacing parts does not provide a solution or resuscitate your device, the only explanation is a failure of the Main Board or the Logic Board.
When a device suffers damage, the obvious problem(s) appear to be a component, for example a screen or a charging port. These component failures are readily and immediately experienced by the user to be the proximate problem. Replacing the damaged or non-functional component would seem to be the obvious solution. Thus, a user comes to The TechKnow Space to have this problem remediated/repaired. Typically the doctor (our seasoned technicians) have no problem doing this.
Sometimes however, replacing/repairing components turns out to be an exercise in futility. Further diagnostics establishes the problem to be resident in the Main Logic Board. The replacement of these logic boards is prohibitive and best left alone. It’s time to move forward to a new device.
Bear in mind that these mainboard failures are a result of the initial damage to the device that prompted a visit to the repair shop even though it is not intuitively obvious.

iPhone 6, 6 Plus, 6S, 6S Plus Battery Replacement

The larger size of these models allow for a slightly larger battery inside the iPhone 6, and especially in the iPhone 6 Plus, which means an increase in battery life. This is good news for any iPhone users who find they are struggling to get their phone through the day without plugging it in for a top up at some point.

The batteries inside modern smartphones are becoming increasingly sophisticated. Not only are they more powerful than ever, but have also become much less bulky and heavy than in older cell phones. These advances in technology have allowed smartphone manufacturers to add more functions to their phones and also slim the physical phones down considerably.

With longer-lasting batteries, the iPhone 6 and iPhone 6 Plus are plenty capable of running multiple apps at once, while taking the title of being Apple’s thinnest iPhone yet. The battery is sufficiently powerful to light up the larger screens, watch videos, play games, operate apps, keep your cellular signal and your WiFi alive, and still last you through the day.

According to consumer reviews across the Internet, the latest iPhone’s battery life is fairly impressive considering its size. On top of that, the iPhone’s charging time has been greatly improved. The battery is charged to one-third (about 30%) after about 30 minutes of charging, and is usually fully charged within two hours.

Apple promises the battery will work as good as the day you bought it for at least 500 full charges. (Which if you need to charge it every day is about a year and a half.) On their website, they promise:

“A properly maintained iPhone battery is designed to retain up to 80% of its original capacity at 500 full charge and discharge cycles.”

Forbes magazine explains what this means for you as a consumer:

“This means that after 500 charge cycles – probably something achievable in 14-18 months for heavy users that charge their iPhone 6 every day – your iPhone 6 will have lost up to 20% of its battery capacity meaning it will only last 80% as long between charges. The longer you continue to use the battery, the more it will degrade.”


If your iPhone isn’t holding a charge for very long, or isn’t charging at all, you might need to get the battery replaced. The batteries in iPhones are glued in place, and then trapped under cables, metal clips and a screen that is screwed shut. Do-it-yourself guides on the Internet will make replacing the battery sound really simple and problem-free, but in reality, your experience will go a little something like this:

  1. Buy a replacement battery. Most reputable sources, like physical store locations, won’t sell you a replacement iPhone battery without doing the repair themselves, so your only option is to source one online.
  • After paying for one, and waiting for 2+ weeks, you hope you get a battery that offers a warranty and is not shoddily constructed or poorly insulated to explode within 6 months inside your iPhone 6 or iPhone 6 Plus.
  • Worst case scenario: you buy a battery online but the battery never gets shipped to you and your credit card information is stolen.

(Are you still convinced replacing the battery in your iPhone is a good idea? Well, read on!)

  1. While you’re window shopping online for an iPhone battery that looks the least suspicious, you will also need to buy a special screw driver or two, a special tool for lifting up the screen, and possibly also tweezers. Now that you have the battery and the tools, you must:
  2. Unscrew the two screws at the bottom of the iPhone to open the front of the phone up.
  3. Use the suction cup tool to very carefully life the screen up. But don’t lift it too fast or you’ll break the cable connecting it to the rest of the phone! Also don’t shatter your screen or you’ll have to replace that too!
  4. Disconnect the cables from the screen
  5. Unscrew the screws holding the other cables in place
  6. Disconnect more cables – but be careful with these too! They control the display and the main functions of your iPhone, so they are pretty important.
  7. Finally, you’ve reached the battery! Undo the cable connecting it to your iPhone, but don’t remove the socket holding it or the battery won’t work.
  8. By this point you should have noticed the fairly scary warning written on the battery about the possibility of injury if the battery is mishandled. So now you have to use tweezers, which no matter how blunt they are, are still pretty sharp, to lift the tape holding the battery in place.
  9. This tape runs over and under the battery, and you need to get every piece or your new battery won’t sit right. (but who knows? It might not sit right because you bought it off some anonymous seller on the Internet, so you have that to be concerned about as well.)
  10. Now that the battery is mostly free, slide a thin card underneath it without bending either the card or the battery (if you can work out how to do that, then that’s it! You did it!)
  11. Now all you have to do is put your iPhone back together and hope you did everything right and that the battery works.

Instead of experiencing all this very cool stuff and graduating as the iPhone battery replacement expert suma-cum-laude,  you could bring your iPhone to the Techknow Space and experience the kick-up-your-feet and let the experts go to work for you:

  1. Bring your phone to the friendly customer service representative
  2. Leave your phone worry-free, or have a seat in our inviting lounge, watch TV and grab a coffee.
  3. Come back to the customer service desk after an hour
  4. Pay and walk out with a smile on your face.

I am sure the second option would leave you feeling less guilty ;)

I had an i-pad screen changed. Very satisfied so far with the end quality of the work. The staff was very courteous and did a good job after an initial hick-up. They put on a black colored screen by mistake instead of a white one. It was already beyond their closing time but they themselves offered to change the screen again by staying open late and without any extra charge. I had to wait a little but left very satisfied with their service. Keep up the good work! Thanks

iPhone 5, 5S, 5C Battery Replacement

iPhone 5 Battery Replacement Toronto MississaugaThe battery lifetime has been improved on iPhones 5, 5C and 5S, however, fundamentally, they use the same Lithium Ion technology. That means that the battery would generally have a lifespan of about 2 years, after which you will notice that the battery doesn’t hold enough charge to last you a full day. So it is time for you to get your battery replaced!

Another problem common to Li-ion batteries is that towards the end of its lifecycle the battery can develop internal current. When that happens, the battery heats up and the electrolyte inside starts to vaporize. That’s how batteries get swollen. iPhone batteries, being incased within the device, can damage the screen or the back cover of the phone.  Typically, if you see that your iPhone 5, 5S or 5C screen starts to lift up for no apparent reason – bring it in to our store in Toronto or Mississauga for a battery replacement immediately, before any damage is done to the internals of your precious iPhone.

We carry all batteries in stock for the iPhone 5, iPhone 5S and iPhone 5C, and are ready to replace it in less than an hour.

iPhone 4, 4S Battery Replacement

iPhone 4 Battery Replacement Toronto MississaugaWe always have batteries for the iPhone 4 and iPhone 4S in stock. Replacing your iPhone battery would resolve the following issues:

  • Your iPhone battery doesn't charge;
  • Your iPhone battery doesn't hold charge;
  • Your iPhone shuts off even though it's showing that the battery still has some charge

If you are noticing that the behaviour of your iPhone 4/4S battery has changed siginificantly since you bought the phone - don't wait and get your battery replaced as soon as possible! If a faulty battery is kept in the device for a longer period of time it can affect other components, possibly making the repairs a lot more difficult and costly! For example, a bad iPhone battery can swell and actually break the back cover of an iPhone 4 or 4S!
