I don't think it would hurt to complain to your dealer about it? perhaps they can reset it? did you vehicle come with it? I had to purchase mine separately. I wonder if there are settings which keep an active sync or sync when you turn the display on? I haven't really played around with mine but I will check it out. |

I did complain to my dealer, and they said it should last "up to 3 weeks". Which is a meaningless statement
Mine was a retrofit, by the dealer. My suspicion is that its the wireless charging i.e. the key stops before its full, even though the display shows it to be full. I suspect the (key) battery remaining virtual gauge is inaccurate. |

I'm currently doing a daily test and log of its battery drain (unused) from 100% wireless charge. I will repeat that from a wired charge after it reaches "zero".
"Zero" being where the display does not work. The key still holds reserve to work the locks and ignition at that point of course. |

Data log & conclusions
Daily LOG with notes. With Key unused, and simply checked daily using an Alexa daily reminder at 9pm.
Conclusions are: 1/ Key battery life is rather short at 16 days. 2/ Battery indicator is faulty, as the battery was depleted virtually as soon as it indicated 50% life remaining. 3/ Battery indicator is not fit for purpose. Outcome: BMW replaced my DisplayKey today under warranty (but new key is not fully working yet, as it has less info and will not pre-condition i8) DisplayKey LOG: Wirelessly charged 100% 10 Feb 2019, 18:29. Display indicates full battery. 12 Feb, 21:14. Full battery 13 Feb, 21:00. Full battery 14 Feb 21:00. Approx 90% 15 Feb 21:24. Approx 90% 16 Feb 21:00. Approx 90% 17 Feb 21:00. Approx 90% 18 Feb 21:00. Approx 80% - hard to be sure, could be unchanged at 90% 20 Feb 21:00. Approx 80% 21 Feb 21:00. Approx 80% 23 Feb 15:42. Approx 80% - hard to be sure, this and above ones could be 75% 23 Feb 21:00. Approx 75% - as above, could be 80% 24 Feb 21:00. Approx 75% 25 Feb 21:00. Approx 60% 26 Feb 21:00. Approx 60% 27 Feb 21:00. Approx 50% - but Key “crashing” and shutting down. This is the usual first sign of v low battery. Screen therefore effectively unusable properly. Then tried to use it again, and key will not activate (display remains off). Placed it on wireless charging pad & tried to activate & charge it. Screen shows charging symbol, but otherwise will not active (boot up). Checked every 30 mins. 27 Feb 23:01. Shows 100% but is still charging. Key can now be used. 27 Feb 23:08, screen self-activated and the key completed charging. |

I've now got my new key, and it's exactly the same. As was the key with the brand new i8 Roadtser I had for nearly 2 weeks.
My conclusion is that all DisplayKeys will only charge to 100% if wire charged. Wireless charging simply does not charge them to 100%. So not a fault but a design issue. |
