I updated my iPhone 8 yesterday and, boy, do I regret it. Whilst I haven't lost any data, my phone is draining battery quicker than a teenager drinking vodka cruisers with a straw. My phone was on 100% charged when I went to bed at 11.30pm last night. All apps were manually closed except for the alarm, as I do every night. I woke up this morning at 6.30am with my phone below 50% battery left from just sitting there doing absolutely nothing. Put it on the charger and it got super hot as it started to charge which it also normally doesn't. Not happy about that. I'm out and about a lot for work during the day and it's a hassle having to drag a charger chord with me wherever I go and trying to find charging ports multiple times throughout the day which I will have to if a few hours on idle drain the battery by half already.
