iOttie wireless Qi with iPhone 8

Using iPhone 8 with iOttie Qi Wireless car charger.

iOttie Easy One Touch Qi Wireless

Use iOttie charger for about a month. I would say it is nice that there is no need to plug in cables any more. What is not that great is iPhone wireless charge speed. It is slow.

Apple iPhone 8 charging time

Charging iPhone using different chargers. Results time depends on charger a lot. Starting from long 4 hours charge using standard PC USB port with 5v 0.5A. Ending with 1h 40m using Apple 29W type-c charger with USB PD 14.7v 2A. Despite 29W charger is actually the best one it cost too much to use it as iPhone charger – 75$ (charger and cable). There is other option available for fast charge iPhone. Apple 12W iPad charger with 5.1v 2.4A. It is only ~20$. Same 1h 40m for 100% charge.

iPhone 8

First look on iPhone 8 and iPhone 7 comparison shows that phones have more in common than differences.

iPhone 8 and iPhone 7 have same:

  • size and bumping camera
  • photos (camera) quality
  • accessories compatibility
  • accessories in the box
  • charging time
  • both need cases

iPhone 8

  • is heavier
  • 20-30% faster
  • support wireless charging
  • support USB PD 14.7v charging
  • have glass back
  • got screen auto white balance (True Tone)

iPhone 7 and iPhone 8

As usual a little bit faster than previous model. Little bit heavier. Same size. Compatible with existing accessories. iPhone 8 support charging with 14.7 volt (up to 80%, using Apple USB Type-C power adapter). But quick charge test shows more or less same charging time for both iPhone 7 and iPhone 8. Same need to use case because of bumping camera. Plus, another reason to use case with iPhone 8 is because of its glass back. It may be broken and it get dirty looks fast.  Minus one reason for the case is less slip grip of iPhone 8. The phone is no longer try to fell from a hand all the time. When using a phone in case it is hard to say if it is iPhone 7 or iPhone 8. Screen scratch protection is still not perfect. Couple of days in pocket with coins and/or second phone – visible scratches. Same USB 2.0 wired sync speed. Type-C to Lightning cable is also USB 2.0 sync speed. Phone does not have Apple wireless charger yet, but Samsung and other Qi charges work for iPhone 8.

Traffic on Apple iOS 11 map

Latest iOS update brings among other traffic data in Kyiv.  In addition, map is less outdated compare to how it is usual in Apple maps. Now map based on OpenStreetMaps.  Routing is far from perfect. Traffic is also not always relevant. But at least map improves.

iOS 11 Navigation with traffic

Good news is that map edits that I did during last year using OSM editor now are in new Apple map. Therefore, the way to fix Apple map mistakes exist.

Some streets names are not translated properly.
