iPhone X here. Same issue since upgraded to 14.2. SEVERE battery drain just texting a few ppl. Taking a 10 second video etc. if I play a 2 minute words with friends my battery drains by 10-15%. Charging it takes over night (7) hours of starting in the 20% range. I now bring a portable charger with me everywhere just to be sure I’ll make it through a few hours away from home. I don’t have background refresher on apps or mail. The only thing I do is answer calls or texts and I’ll be between 40-50% after 2-3 hours. Most of the time it’s in my pocket. Gets HOT when charging
