iOS 14 battery life

An update... 14.0.1 now and fully factory reset the phone twice, it still drains like crazy even during idle.
"Usage by app is not available for xx:xx-xx:xx", so no apps are using it.

What's concerning is that now my SE 2020 went to 98% battery health after only 2 months and 40 charge cycles.
I never let it discharge below 20%, and never let it plugged in after 100% or overnight.

Is anyone else having similar issues or I got a lemon?

I got my SE 2020 less than a month ago, it’s down to 99%, battery life is rubbish on iOS 14 and I’ve tried everything to fix, it’s about 30-40% worse than it was on 13.7

Yeah, the same here. My phone was 45 days in use since I bought when I installed iOS 14 and the next day battery drop to 99%. Apple says it's normal, that I hav got 30 cycles and blah blah blah.

I made a ruler of 3 and more or less 25 cycles are 1%. What I can't understand it's how there's people getting 100% with 8months. What I'm doing right now it's charger between 20-80% even 30% and if I can, put the charger, no more than 95%.

I disable almost everything in configuration/privacy.

Oh, and I did a downgrade because it was possible to 13.7.

in my experience and opinion, it's a matter of luck and what you're battery looks like right when you get your phone. if you use Coconut battery, you can see the design capacity and actual capacity of your phone's battery. i have had phones come just right about 100%, and some that start off at 104% of the battery capacity. with this difference alone, we would expect a fair bit of variation from unit to unit.

beyond that, without any change in use nor charging habits, i've seen some batteries decay in their actual capacity at a faster rater than some others.

i do imagine than charging between 20-80% is the most ideal, but there is still a significant amount of variation in batteries themselves.

Not that it is relevant to this power usage bug, but.. charging the top 20% wears out the battery much more than the bottom 20%. But I wouldn't worry too much about it 😅

Some batteries just have some more damaging substance in them (for example water) that makes them break down much more. If you'd like to find out, you can get a job discovering and counteracting all the ways batteries can break 👍😬

My XS is on 14.0.1 and I have not noticed any additional drain on the battery since updating from 13.7. FWIW my battery health is at 84%. Holding out for the 12 Pro rather than replacing the battery.
 
I've been quite pleased with the battery for 2 years, it's got me through the day mostly. Charge every night to 100 and listen to radio 2 hours and have sound apps for tinnitus in bed, and every morning it's probably around the 60% which I think is great. However..... iOS14 happened!

It's horrendous and I'm gutted I updated to it because the battery doesn't even get through the night and you can just watch the percentage go down. Is this common with the iPhone 8 and any other models. The usage that the phone shows what is used to drain battery doesn't even show the two things that were used in the night, which it always used to with 13. It shows Safari at top which is completely wrong

Is there an easy way back to 13, or something that fixes 14, Thanks for any help and advice. Have done all the usual save battery YouTube type ‘hacks’ and all of them were already off.

Here’s my report on my X.

Charged to 100% and unplugged when I woke up and drained down to 85% after 10 minutes of usage - browsing safari, IG, checking email

Reporting back again on the battery issue. I just got to my office and my battery would usually sit at about 88%. It’s at 65% now.

Note that it was plugged in on my commute as used it for music, podcasts etc.
 
Last 20 messages only guys with iphone 6s, 8 plus, 7... Old phones with battery health 85-90.....
 
I meant on that link you ‘ve posted. Battery life is worse, but for me, only on LTE (11 PRomax). I am not saying problems don’t exist, but it is crazy that people with 6s, that is 5 years old and with 85% battery health complain all the time.
 
For some reason my iPhone SE 2016 (replaced battery in February, so 100%) has returned to somewhat normal battery drain. Just had it take 16 hours from taking it off the charger to somewhere near 20%, no Low Power Mode on. Which ought to be able to have gotten me through a normal pre-epidemic workday.

I did do all the tricks, like restore, removing iCloud and adding it again. So it's hard to say if anything I did fixed it. Or that Apple is pushing fixed to phones to try to fix things.

I do notice that the drain is still kind of flat, e.g. not much difference between usage and standby.

I guess this is where you’d see a greater stress on the battery - somewhat older hardware with an aging battery with a new iOS taxing the system more.

You clearly hadn't been in that situation. I had a 6s before I upgraded to 11 Pro last year. On iOS 13 the percentage dropped every two seconds just while the apps updated in the background. The battery was at 97% health and only replacing the battery fixed it. The issue persisted even after a factory reset and nothing else installed. Apple store employee refused to change the battery unless I pay for it. I told them it’s only been 5 months since I replaced the battery so I’m not paying.

I left home and left a nasty review of my experience with the visit and the store manager called offering me a courtesy replacement which fixed the issue. Nonetheless the battery started draining like there’s no tomorrow after just a few months and I had to charge it 2-3 times a day. Decided it’s best to upgrade considering the improved battery in the 11 Pro.

So don’t tell me it’s crazy.
 
I've got SE 1st gen with 11 months old battery (replaced through Apple). iOS 14 melts through battery, even thought I tried clean install. I regret upgrading a lot. If I leave my phone idle for night, I lose about 30% battery and 'battery setting page' shows that nothing was running at the time. It's even worse when using it. I picked it up today fully charged at 7AM local time. 40 minutes of podcasts later, a couple of short YT videos (LTE good reception), one 20 minute call and a bit of Messenger: 35% at 1PM right now. It was much better on iOS 13.

In contrast, my old pap just got Redmi 9 for about 100$. Yeah, it's cheap Chinese phone but I must say for the money, you get a load. And what struck me: I set it all up, installed tons of apps, upgraded Android and logged him into every possible service and banking (probably 1.5 hours worth of work) and it ran down only 5%. My SE would be at 5% left after such chores.

It’ll be interesting to see how this new small iPhone 12 fairs out, it’ll only have a small battery, won’t be a good look if it’s struggling on iOS 14
 
I had battery drain yesterday in idle especially, i went to sleep and when i woke up the battery was 60% from 81% and it usually drops 2 or 3% at max... no app activity either in settings. iOS 14.0.1 has a battery drain problem for sure.
