Connect iphone with usb

Question: Q: iPhone connects and disconnects from Mac

When I plug in my iPhone to my Macbook pro, it repetitively connects and disconnects. Therefore I cannot charge my phone through my computer anymore.

I own this iPhone since decembre 2018, and this issue only appeared this week. However when I plug in my iPhone to a wall outlet, it charges perfectly. I also noticed that there is a lag time before my phone starts charging when connected to my Macbook (before disconnecting right away, and then reconnecting etc).

I tried to connect my iPhone to both USB ports of my Macbook, with many different Apple lightning cables and also my Anker cable (MFI certified), but the issue substains. I plugged in my mother’s iPhone 6 to my Macbook and it charged perfectly. I plugged in my iPhone to my brother’s former Macbook pro (15″ from 2008) and my iPhone could charge normally.

Here everything I tried to resolve this issue (which failed by the way) :

— I shut down and turned on my computer and my phone.

— I also restored my phone.

Could anyone tell me a solution?

I specify that I have a 256Go iPhone X under IOS 11.2.5 and a 13″ retina Macbook pro (mid 2014) under High Sierra 10.13.3.

I had same issue on my iphone 6, ios 9.3.2. After searching through the web i found following solution that helped me:

You need to reset your privacy and location info and then trust your iphone with itunes again.

1. Disconnect your iphone from cable.

2. On your iphone: ->Settings -> General -> Reset -> Reset Location & Privacy (accept all things).

3. Connect your iphone back to cable. (iphone will reconnecting again, don’t worry, it will be soon over).

4. iTunes will ask about trust, accept all this.

After that your iphone should stop reconnecting repeatedly and start to charging normally.

But I do think I solved my problem, by something similar.

On the hunch that the computer was trying to set up a network connection via the phone while the phone was trying to do something else, I went into the network settings and found that in the list of services I had an entry for «Thunderbolt Bridge.» I thought it was off, because it was listed as Inactive and the configuration I could see said «Configure IPv4: Off». But to make sure it was really completely disabled I pushed the «Advanced» button to change the configuration details (after clicking the lock icon and authenticating, of course). I changed «Configure IPv6» from «Automatically» to «Manually» and saved that.

After that, connecting my phone to the laptop finally worked. I was just now able to get some pictures off my phone onto the laptop.

I think I found a solution after much research.

On the mac, go to settings>Network> iphone USB> then uncheck the box that says «Disable unless needed»

This worked for my iphone 7

I hope this helps!

I have an iPhone X and MacBook Air. I have done everything and nothing fixed it. Tried this and seems right. I hope Apple figure it out and fix it in new updates, however, I’ve seen that people have had this problem from 2013.

I just wanted everyone to have the solution here that way when others experience it, they can hopefully find this solution quickly. Luckily several of you like ( MrArifFikri ) touched on the solution already, I’ll just specify the reason for clarity.

It comes down to power, or more importantly «current». Specifically, with an iPad, USB power consumption is very finicky. So in order for the USB direct connection to your PC, USB hub, or laptop you need to make sure your iPad is charged to over 51% . This will reduce the power draw the iPad will attempt to pull from the USB connection. This should give you flawless charging and syncing capabilities. Now you can sidestep this in some cases by using USB ports on your hub, PC or laptop that are closer to the power supply, or series on the circuit board.

If your iPad is below 51%, you need to use the «cube» or power block that came with your iPad. (The smaller one for your iPhone is not recommended as it lacks the internal transformer that the iPad power block has) The reason for this is that your iPad is attempting to draw too much current from the USB connection through a substrate, i.e. the PC, USB hub or laptop connection. They are only designed to allow a limited amount of current through those connections, thus your iPad continues to «trip» the charging circuit in the device because the power draw is too low.

I hope this helps stop the «doodledee. deeedledoo» beeping madness you’re experiencing! 🙂

Use iTunes to sync your iPhone, iPad, or iPod with your computer

Learn how to sync music, movies, and more using iTunes on your Mac or PC.

If you’re using macOS Mojave or earlier or a Windows PC, use iTunes to sync content to your devices. Before you use iTunes to sync content to your iOS or iPadOS device, consider using iCloud, Apple Music, or similar services to keep content from your Mac or PC in the cloud. This way, you can access your music, photos, and more on your devices when you aren’t near your computer. Learn more about using Apple Music or iCloud Photos instead of iTunes.

If you use iCloud or other services like Apple Music to keep your content up-to-date across all of your devices, some syncing features through iTunes might be turned off.

What you can sync with iTunes

• Albums, songs, playlists, movies, TV shows, podcasts, and audiobooks.
• Photos and videos.
• Contacts and calendars.

iTunes features might vary by country or region.

Sync or remove content using iTunes

5. Click the Apply button in the lower-right corner of the window. If syncing doesn’t start automatically, click the Sync button.

* You can only sync your device with one iTunes library at a time. If you see a message that your device is synced with another iTunes library, your device was previously connected to another computer. If you click «Erase and Sync» in that message, all content of the selected type on your device will be erased and replaced with content from this computer.

Sync your content using Wi-Fi

After you set up syncing with iTunes using USB, you can set up iTunes to sync to your device with Wi-Fi instead of USB.
