Airtag—遺失東西的習慣，消失了。

人地有心偷嘅話
丟咗粒tag已經得

我都想買個睇吓有冇用
有次喺K11揾唔番架車

你粒tag收得埋, 唔畀人掉左就得既

咁可以收埋粒tag....無人叫你就咁擺係當眼處

咁幾好 23號唔知落去鋪頭有無現貨賣呢

停車場唔會成日有人係入面，咁你要搵車就靠自己部電話周圍行，咁airtag就冇用啦

佢真係完全抄Tile

1. The Find My app can help you locate a missing Mac — even if it’s offline or sleeping — by sending out Bluetooth signals that can be detected by nearby Apple devices. These devices then relay the detected location of your Mac to iCloud so you can locate it. It’s all anonymous and encrypted end‑to‑end so no one — including Apple — knows the identity of any reporting device or the location of your Mac. And it all happens silently using tiny bits of data that piggyback on existing network traffic. So there’s no need to worry about your battery life, your data usage or your privacy being compromised.

2. 你可以繼續用傳統Find My 但熄crowdsource Find My network

我遺失左個初戀，唔知買咗佢搵唔搵得返!!

可能佢買10幾20粒然之後趁人哋唔為意，放一粒落去跟住人哋返屋企。

大把場搵死人

唔駛FF 喇, 咪話咗有on/off

加密人地用咗hardware AES accelerator 好多年喇
PC CPU 既例子就係AES-NI, 人地講緊volume 係GBs per second, 何況呢度衹係要en/decode 幾串alphabets 咁輕鬆

HW accelerator 比起SW implementation 有咩分別你知嗎？

我唔知你係生性多疑定係inquisitive

如果個sw implementation 要wake CPU 大核就絕對唔止慳咁少
要lab test 就唔會有相關媒體或者youtuber 陪你喇但可以俾個blackbox testing 思路你:
toggle on/off Find My Network and record standby time

whitebox testing 就係developer 自己知系統幾耐會piggyback send back 一次data 同幾耐collect 一次data, 用frequency 同每次operation 用到既電力評估到power consumption impact
但你要留意佢本身同Apple server 之間都會send data (Settings > Celluar > Apple services) 情況會係e.g. send 40KB data 呢個operation 會唔會一定食電過send 35KB data

另外藍牙本身開住都會有periodically scanning
否則AirPods 個開盒泊埋即用功能都唔會activate 到

一嚟Find My network 功能出咁耐都冇人投訴佢感知上食電咗
二嚟phonebuff 都好多battery test 唔見用iOS 14 而且電池縮水既 iPhone 12 系列至少比起11 有退步

最後你做咁多功夫隨時iPhone 13 加厚機身就nullify 你辛苦搵到既效用證明
真係少咗1% standby time? 比你測完人地13 都嚟緊同舊電大咗n%

巴打, 你唔識可以出少句聲

Find My network 搵到你offline 既iPhone, iPad, iPod Touch, Mac, Find My accessories, AirTag 全部都同一原理
而以上呢堆加埋 (龐大既iPhone 數量) 未必會少過第時既AirTag

你純粹睇返段原文有"Mac" 以為原理唔通用就柒咗喇

將來人人出世植入


不過而家都買左先
