Big test for mine yesterday coming back from Scotland. Off charge at 7am and then an 8 hour coach ride with mixed no signal, 2G, 3G, 4G and 5G coverage, i watched a 2 hour film, read flipboard, used Facebook, used twitter, sent messages via Signal, sent messages via Google Messages, listened to some music using Poweramp, got home posted loads of photos on social media (finally back on Wi-Fi) and at 9pm last night i had 40% left and had to put it on charge for the December update.
Mine is fully stock, Wi-Fi left on, Bluetooth is on for Fitbit connectivity and Covid tracing, NFC is on, AOD off.
