- Add more capacity to the internal battery. iPhone: >3Ah, iPad: >10Ah.
- Improve the structural weaknesses and usability of Lightning (to USB) cables. See these reviews and these articles. The main issues are:
- Cables break easily, especially just below the bend protection
- Damaged or worn cables can short out and start to burn
- The cable jacket can start to crumble, possible due to material choice
- 'Accessory not supported' message can appear even with MFi or Apple original cables
- Add stereo microphones to all iDevices. This will prevent mono-only video's when shot on an iDevice.
- Introduce black Lightning-to-USB cables.
- Replace the Lightning connector with USB-C on all Apple devices.
- Create a quad-core A-series SoC to improve multithreaded app speed.
- Add support for LTE X13-X16 (3GPP Rel 12-14).
- Refuse (technical and ideological) support for LTE-U to prevent WiFi band pollution. See this article.
- Add support for 802.11ad (57-66 GHz).
- Add front-facing speakers to the iPhone and iPad; the current iPhone speakers are not loud enough.
- Add a small (color) LED indicator to the front of iDevices. Add an entry in the Settings menu to configure this LED to respond to f.e. incoming mail, iMessages etc. Currently only the LED Flash can be used for this purpose (accessibility feature).
- Add a second SIM bay for dual-SIM functionality.
- Remove the mandatory SIM insertion while activating an iPhone. Some users prefer to use an iPhone without SIM card (WiFi-only).
- Add a haptic feedback motor to the iPad. This is useful for games and accessibility feedback.
- Add 3D Touch to the iPad.
- Enable the LED flashlight functionality by double-pressing the power button.
- Go to the previous app by press and holding the home button.
- Add support for Qi wireless charging. Alternatively, add support for distance charging.
- Add support for Quick Charge to iDevices. Possible standards: 5V (>2A), 9V, 12V (QuickCharge Type A) or 20V (QuickCharge Type B)
- Place the Power & Volume buttons on a different location than on the iPhone 6/6s. These buttons are at opposite sides of the device, which makes it cumbersome to use.
- Give apps direct access to navigation details like the number of locked satellites, constellation type (GPS, GLONASS etc) and other info. See this page for more details.
- Add an 'eraser' functionality to the back of the Apple Pencil, so it can be used like an analogue pencil with rubber eraser tip.
- When charging the Apple Pencil, the iOS GUI shows no indication of the charging process, nor any way to determine what charge is present in the Apple Pencil (f.e. a % value).
- Add a space on or in the iPad to store the Apple Pencil.
- Not all image file types can be imported with the Apple iPad Camera Connection Kit. F.e. screenshots made on macOS can't be imported in iOS.
- Allow 2 Bluetooth headsets to listen to 1 source, f.e. an iPhone. This is ideal during a duo workout.
- Add an IR booster to iDevices and open up an API for third party developers. Possible uses: control external devices like TV's, receivers etc.
- Add a FM/DAB+ tuner to the iPhone and iPad (f.e. enable the FM section of the Murata 339S0228 chip in the iPhone 6). This would be ideal for real-time media consumption without the need for a mobile service or -signal. Optionally, add a DMB/DVB-T tuner to the iPad for mobile TV uses. See this article for more information.
- Add a 'shatter-proof' display to the iPhone.
- Add 'always-on' displays to both iDevices and the Apple Watch.
Add proximity sensing abilities to the display.
- Stop using non-standard Pentalobe and tri-point screws. Instead use Philips screws to improve repairability.
- Improve the scratch resistance of screens. Notably, the iPhone 6 screen seems to be more scratch sensitive than previous iPhones.
- Please prevent the use of glue in Apple products. This would greatly improve the repairability of the device.
- Create an expandable Mac destop computer, like the 1st generation Mac Pro.
- Create an expandable Macbook Pro (RAM, CPU & GPU aftermarket upgrade options).
- Place the power button on an accessible location, not at the back of the computer, like on the iMac and Mac Mini.
- Add a delete button to all Macbook keyboards.
- Improve the support for Continuity on older Mac computers. See Dokterdok for technical details.
- Bring back a 17" Macbook (Pro) option to the lineup.
- Bring back a matte screen option to the Macbook (Pro) and iMac lineup.
- Add an (optional) 4G/LTE modem to the Macbook (Pro).
- Add an optional quad-core i7 CPU for the Mac Mini.
- Create an Apple Keyboard with black keys and/or LED illuminated keys. Optionally, add e-ink displays to the keys to allow for keyboard layout changes.
- Improve the recyclability of Apple products. See this article.
- Stop using non-standard Security-Torx or Pentalobe screws.
- Please prevent the use of glue in Apple products. This would greatly improve the repairability of the device. See the AppleTV for inspiration.
- Macbook power adapters don't have (ferrite) noise filters to block powerline ethernet signals; they interfere with the audio circuit of the Macbook.
- Improve the USB 'unmount' operation. a) it takes longer to unmount an USB stick on macOS than on Windows and b) it would be nice if the unmount operation itself can be eliminated for better usability.
Upgrade the current USB 2.0 connection to USB 3.0. This will greatly improve the transfer speeds to external harddisks.
Add Powerline Ethernet support (IEEE 1901)to Mac(book) power supplies. Normally you would need a Powerline Ethernet device (to plug into a mains socket) and an ethernet cable or built-in WiFi hotspot to connect the Mac to the Powerline Ethernet signal. Implement Powerline Ethernet directly in the Mac power supply and allow it to pass the ethernet signal directly via the mains power cable to the Mac, eliminating both a Powerline Ethernet device and/or an ethernet cable, combining it all into one (mains) cable.
Implement this as well in the Airport Express and/or Airport Extreme to make it function as a supplier of Powerline Ethernet signals into the home mains grid. This way all the Powerline networking can be integrated into existing Apple devices, streamlining the user experience and delivering high bandwidth, even in areas with Wifi band pollution.
- Create a Bluetooth 3.5mm dongle. See this mockup for inspiration.
- Create a cheap audio-only Airplay adapter. This device would be ideal for adding Airplay support to older/unsupported audio devices like amplifiers.
