Battery draining

i agree with quicktimekirk, but also check your battery health, especially considering your phone, maybe if its decently low, like maybe around 85% or below (normally 80% health is fine for new phones like the iphone 11 and stuff but considering your phone is the first gen iphone se, i'd consider 80% to be bad for your phone because it didn't have excellent battery life to begin with), you might want to see if you could get the battery replaced, the new update is VERY intensive on various things like animations, contrast (color wise), a lot of stuff like that which may be hard for a phone like yours (i honestly am presuming its old, it is the first gen after all), or maybe you could upgrade to a newer iphone, its all up to you, but definitely check battery health, and check just the battery section in general and see if there's anything you could optimize, like maybe you have a third party widget that takes up 56% of battery, definitely either delete the app, or just remove the widget, stuff like that.

QuickTimeKirk, how unhelpful! I have the same issue which started straight after I updated to iOS14.1. I have now updated to iOS14.2 and it hasn’t improved. I don’t use Apple Watch or Health, which others have found caused the issue. I always turn my phone onto low battery mode as soon as I take it off the charger and it used to last all day and now I have to charge it two or three times per day. I am on an iPhone SE 1st gen, but it isn’t all that old.

I might upgrade if the new SEs were as small as the 1st gen , but the new SE won’t fit in my pocket because it is bigger. I also like the home button and I like the large bezel which makes it easier to hold with one hand if you are taking photos at a stretch, or don’t want to keep accidentally touching links and having your screen cut away to to something random.

I am having the same problem. iPhone SE 1st generation, 128GB. I love my phone. It isn't even 3 years old. The battery is suddenly dropping 1% per minute or less! The phone doesn't even last an hour unless I put it in low power mode and even then it doesn't last long. Previously it was lasting all day. There has to be a fix. I have tried all the battery saving strategies with no luck.

That's what batteries do.

Charge it more often.
