    Any recommendations for a multi-port charger that stops charging iDevices when the device reaches full charge?

    I've used many of these third-party multi-port chargers (e.g., from Anker) and they keep sending a charge to the device after the battery has hit 100%. This results in the device buzzing or sounding a tone signaling a full battery charge over and over––a terrible annoyance when sleeping.

    apple devices switch the circuit off when fully charged. they switch it back on when the charge drops. Its all built into the software following apples philosophy, it just works, you shouldn't have to think about it because we did it for you. Just plug it in and be done.

    ^ So why is it that my devices repeatedly buzz and show the "battery full" notification when using certain third-party chargers? (Anker's chargers, as I mentioned, are evergreen culprits.) I've never had this problem with Apple's chargers.

    As above its the device not the charger that stops the charging phase. The control circuit has been in the actual device for a long time now.

    I had similar issue once with a third party cable. Try that same cable with Apple charger and see if it still happens. Or try an other cable with that charger.

    Also iOS devices don't make any noise when they hit max charge. They do make a noise when they are plugged in to a charger though.

    That's the noise I'm hearing! It's the "starting charge" notification that I'm hearing and seeing. So why might I be seeing that repeatedly after a device hits a 100 percent charge?

    It seems that for some reason the connection between the charger and device drops and then it connects again and so on. Either the charger, the cable or the device is faulty or incompatible. Switch one component at a time to find where problem is. You could try that charger and cable with someone else's device.

    Basically any USB-charger should work. Some (cheap) third-party cables might not. Also check the cable that there aren't any visible damage.

    Use the Belkin Conserve Valet, it stops charging when devices reach full.

    Charge M.E. is also one of the best multi port USB charger suitable for any commercial or residential space. You can use this device to charge iphones, ipads, tablets, android phones and other gadgets. It will also solve your purpose.

    So if it's still connected while it's at 100% it's actually using the battery until the charge drops a certain amount instead of using power directly from the charger? I've heard conflicting reports about this so I'm curious if there's a definitive answer to this.
