Introduzione

If your iPhone 11 Pro Max screen is cracked, not responding to touch, or not showing a picture when your phone is powered on, use this guide to restore your iPhone to working order with a new screen, a.k.a. display assembly.

The combined earpiece speaker + sensor assembly affixed to the back of the display is paired to your individual iPhone from the factory, so you must transfer it from your old display to your new one during any display replacement. It contains the flood illuminator, which is part of the biometric Face ID security feature. If it is damaged or replaced, Face ID will cease to function, so take extra care not to damage any of these components during this procedure. If damaged, only Apple or an Apple-authorized technician can restore Face ID function.

Note: True Tone functionality is disabled after a screen replacement, even when using an original Apple screen. Additionally, your iPhone may temporarily show a warning about the “genuineness” of the display.

  1. Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured. Power off your iPhone before beginning disassembly.
    • Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Power off your iPhone before beginning disassembly.

    • Remove the two 6.7 mm-long pentalobe screws at the bottom edge of the iPhone.

    • Opening the iPhone's display will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your iPhone without replacing the seals.

  2. If your iPhone has a cracked screen, keep further breakage contained and prevent bodily harm during your repair by taping over the glass. Lay overlapping strips of packing tape over the iPhone's display until the whole face is covered. This will keep glass shards contained and provide structural integrity when prying and lifting the display.

    • This will keep glass shards contained and provide structural integrity when prying and lifting the display.

    • Wear safety glasses to protect your eyes from any glass shaken free during the repair.

    • If the broken glass makes it difficult to get a suction cup to stick in the next few steps, try folding a strong piece of tape (such as duct tape) into a handle and lifting the display with that instead.

  3. Heating the lower edge of the iPhone helps soften the adhesive securing the display, making it easier to open.
    • Heating the lower edge of the iPhone helps soften the adhesive securing the display, making it easier to open.

    • Use a hairdryer or heat gun or prepare an iOpener and apply it to the lower edge of the iPhone for about a minute in order to soften up the adhesive underneath.

  4. The next two steps demonstrate the iSclack, a handy tool that we recommend for anyone doing frequent repairs. If you aren't using the iSclack, skip down two steps for an alternate method. If the plastic depth gauge is attached at the center of the iSclack, remove it now—it's not needed for larger iPhones like the iPhone 11 Pro Max.

    • Position the suction cups near the bottom edge of the iPhone—one on the front, and one on the back.

    • Press both suction cups firmly into place.

    • If your display or back glass is badly cracked, covering it with a layer of clear packing tape may help the suction cups adhere. The iSclack also includes two pieces of tape for this purpose.

  5. Hold onto your iPhone securely and close the handle of the iSclack to slightly separate the screen from the rear case of the phone. Don't try to completely separate the screen; a small opening along the bottom edge is all you need. Insert an opening pick into the gap under the display on the lower edge of the iPhone.

    • Skip the next two steps.

  6. If you're using a single suction handle, apply it to the bottom edge of the phone, while avoiding the curved portion of the glass. If your display is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken screen.

  7. Pull up on the suction cup with firm, constant pressure to create a slight gap between the front panel and rear case. Insert an opening pick into the gap. The watertight adhesive holding the display in place is very strong; creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, apply more heat, and gently rock the screen up and down to weaken the adhesive until you create enough of a gap to insert your tool.

    • If you used an iSclack and it's still affixed to the iPhone, remove it now.

  13. Open the iPhone 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. Lean the display against something to keep it propped up while you're working on the phone.

So far the newest iPhone I have repaired is an iPhone 7 - should I give the 11 pro a go?

TheRe - Replica

iPhone XS Max, a bigger phone format of the 2018 flag-ship iPhone comes with a battery of 3,174 mAH. That battery can be significantly large for a few and not so much for a few. The battery life, as claimed by the manufacturer, does vary when put to use.

Depending on your use, if you use your iPhone XS Max for browsing, calling, and checking a few emails. The in-build battery is pretty good for you, but in case you are a pro user, it might not be. That means you are making the most out of your iPhone XS Max.

And after the half-day, there is a possibility that you are falling short of the battery power in your iPhone, but your work is yet not completed for the day. In that case, either, you can get a charger and look for a charging port and stay near it until the iPhone charges. Or, get a … '''Read More'''
