I would recommend going into the windows repair settings, and fully erasing/resetting the computer. If you are not able to do that, then here is what you must do: (1) Go here: https://www.microsoft.com/en-us/software-download/windows10ISO and put this ISO file onto a bootable USB drive (2) Once this is installed you can use the USB to reset the computer. Fully turn off your computer and restart into boot options. (to get to boot options it should be one of your F keys that you press while it starts up. The computer will tell you, keep your eyes on the top corners of the screen. (3) Once you are in this menu click on the USB to boot into. (4) Then go through the menus until you reach where it asks you which drive you to want to install windows 10 on. First, click on each drive and press delete. This will delete all of your data (but there is no other option, your windows are corrupted). Once everything is deleted, click on your main drive to install windows on and continue. (5) Continue the process as the...

Hi, This is likely because of the physical battery in the device. If you use one of them significantly more than the other it can negatively affect the battery. Using one a lot more than the other will cause it to have more cycles and cause the battery to deteriorate faster. Unfortunately, the batteries on airpods tend to die after ~ 1 and 1/2 years, and the batteries are essentially unreplaceable. It might also be that you keep one plugged in far too much, causing the battery to deteriorate from always being connected to power. Edit: As mentioned below, you could also disable siri in one of the airpods, which may decrease power consumption. Apple tries to do always on Siri so that it is always listening and ready for you, but this isn’t always necessary and can be a drain on battery.

Hi, This is just a function of the software. The volume for headphones, Bluetooth devices, Siri, and onboard speakers all have different volume memories. The volume will always default to whatever it was the last time you used the device. e.g: Plug bluetooth speaker in and turn volume to 5, disconnect it from the phone and the main phone volume is at 3. When you turn up the phone (without the Bluetooth speaker) the phone’s volume will increase to 6, but after reconnecting the speaker it goes to 5 (the volume that speaker was last at) if you were to disconnect the speaker, it would go back up to 6.

The battery may no longer be secured to the logic board, before replacing the battery try to open the device and fasten the power connector first. If its loose light movement, or just sitting over time could cause it to power off. BTW coconut battery is usually correct, apps on iPad usually get it wrong.

If you did it yourself then probably not as the adhesive is probably not as strong as it was at release. DO NOT trust it in the water. Its still risky even if apple did the repair as they will not replace any device for water damage even if it is within warranty and you kept the phone with in the water resistance limits. Also its water resistant not waterproof.

It could just be an alignment issue, is the metal part of the home button bracket (which is the contact for the button) aligned with the center receiver of the home button?

Its most likely that the connector is incorrectly attached. There is a 99% chance of that being the issue. 1% chance that you have a bad part. It is most likely that you incorrectly plugged something in on the inside.

They are not interchangeable. The u is for T-Mobile only while the u1 is unlocked for all carriers. Changing them would not work on a non T-Mobile network. To get even more specific it will only work on T-Mobile within the US. Changing the u to the u1 should work fine however

It may be that you forgot to plug back in a component such as a separate GPU so the system is running off of a weaker GPU that comes standard soldered to the motherboard. You may have also forgotten to plug in a fan so the CPU is throttling itself to be slower since its not getting the cooling it got before. Look at all components again and make sure that everything that should be attached, is attached/plugged in.

Review this and see if you can solve it with what they talk about: https://www.macworld.co.uk/how-to/iphone/fix-frozen-iphone-screen-3626629/ Otherwise try taking the display off and cleaning the glass on the inside. If that does nothing then yes the digitizer is the part that does that, so that would need to be replaced.
