I understand people are suggesting to turn off screen time, don’t use fb and WhatsApp etc but that won’t fix anything.
This is my usage after taking off charge 11 hours and still on 50%. I Always use backup to restore since original iPhone , using iPhone X with battery health 98%.

I know battery took dive after iOS 12 release but Turning off features won’t help in my opinion, this need to Fix from apple side, I don’t kill apps in background except fb and gps apps.

Your picture showed some hours with a lot more usage than other times - do you know what you were doing during those times? Maybe some apps don't run well under IOS 12. Did you do anything different during those times or were you on cellular vs. WIFI?
 
12.0.1 released hopefully this will fix the problem??

Unfortunately mine has drained just as fast today on 12.0.1.

Charging my phone to 100% and then letting it drain...

Same. And I am going to charge via the adapter included with the SE in its box instead of the iPad charger I was using. Someone posted it may have an effect. I doubt it, but worth a shot. Apple was pretty forthright in what today’s update fixed in its description, and it did not mention fixing the SE’s battery drain. If an update includes that, I think they will mention it in that update’s description.

Also experiencing worse battery life since updating from 10 to 12 on my SE. My 6 has had no such issues. All the more odd since my SE was the one with amazing battery life. Weirdest part is that the battery percentage drops in batches. It'll be a 50% and then drop to 48 or 47% while I'm looking at it (not doing anything major, not using GPS or watching a video). I've been through plenty of updates and never seen this before.

When I did the update, I was charging but the battery percentage still dropped 10% and the SE was REALLY hot after. Battery health at 90%

Hmmmm I think the battery life on my iPhone SE is quite good for how small the battery is. 100% health as well. It’s my secondary device. I do the same things on it as I do with my primary device (iPhone X).

Upgraded iPhone SE from 11 OTA. No DFU restore or anything. I guess I got lucky.

Hi there guys, I’m back. After updating to iOS 12.0.1 OTA my iPhone 6s 64GB last night and let it charging overnight (around 10 hrs of settling down) I have used this morning my device for around 59’ and battery was still at 87%. Maybe a bit early to tell, but I remember using my phone for an hour and seeing it around 75-80% in iOS 12.0.0...I also counted the time from the battery app and they seem to be the same from the “Screen Time” app. Just my two cents. I’ll get back to you at the end of my day...

Greetings from Spain.

Woke up this morning and my battery "suddenly suck". This happened for the first time, it basically fell from 50ish % to 2% when I woke up(2am to 9am). The last app I used was Photo app, battery has been perfect since day 1 iOS 12. Not sure what is eating the battery overnight because I have background app refresh completely turned off too.

Perhaps it's too soon but I think the 12.0.1 update has improved my battery life. My battery % hasn't dropped by multiple increments yet. Further testing needed but it certainly didn't make anything worse. I didn't install new or restore....just updated

Update: false alarm. Battery life is the same (bad). It seems fine (going down little % at a time at reasonable increments of time) but then it'll drop 4-5% in 2 minutes while I'm doing basic usage (not youtube or facebook)

I was just wondering, when people do these clean installs to make sure everything is "neat and tidy" with no possible dragged settings how do people get their contacts back? I've got over 200 contacts? Do you back that up to icloud and then simply do a restore? What about WhatsApp chats? Messages? etc..? Sorry I've never done clean installs before and I seem to be experiencing this battery issue on my SE and wanted to rule the clean install option out.. (battery usage is 99% so hardly any wear)..

I don't think that will help either, I have backup going from original iPhone and always restore from backup on new iPhone each year.
I have a brilliant battery life, as I mentioned above as well, I did get some battery hit on iPhone X after iOS 12 and getting better on 12.0.1 now so it is not how you using it or fresh install issue.
Apple will need the fix from their end or maybe some apps causing issue on SE, check battery stats and see.

just find android as replacement backup. If i can use ios 10 i would stick to iphone 5s longer then suppose to.

Yea, I thought so too. I thought maybe I would give it a go but all the evidence suggests its an IOS 12 issue.
But in general how is a clean install completed when it comes to messages and contacts?

Don’t get the XR, be patient if you can, you can almost be assured it will be fixed sometime in the future with a software update. It’s not the phone that’s the issue.

If youre operating on iOS 12 you should be able to look at the battery health in settings, under battery/battery health. try to notice anything odd, but what you want to look at is the capacity. If it is above 80% then the battery drainage is not the battery. If the phone drops chunks of percentages and gets really hot, it is rare that the issue is solely the battery unless the battery is swollen. Software issues can cause overheating as there is something taxing the battery much faster than any normal process the phone would be doing. Phones can get hot, remember phones don't have a way to vent, as computers do. If its just sitting there, not on a charger, and getting hot, thats odd, I would have the battery looked at but my money would be on software. Back up to the cloud, erase all content and settings, and set up as new. issue gone.

Totally agree... what a terrible terrible mistake!

I thought Apple said iOS 12 was going to make older devices run great?

if not, it will in my closet. After a year then i buy second hand 6S. it just for my testing purpose only. Not trust as main gear anymore.
 
I had an experience that may or may not be relevant. I'll share it just in case.

Always had good battery life on my iPhone 8 on iOS 11. After I updated to 12.0, battery life was about half. Hard to make quantitative comparison since, of course, they changed the measurement criteria with iOS 12. But I had to recharge about twice as often.

The most noticeable thing was that "Mail background" was now showing up as the app with the most battery drain. This was strange, because with iOS 11 my news apps such as NY Times, Google News, were always showing as the most battery usage. And I did not change my usage habits.

So I spent a lot of time checking all the settings on the apps such as background refresh, etc. and nothing seemed to be different. I also tried closing and reopening the "Mail" app, but that didn't help either.

Then, a couple days ago, I just turned off the phone completely and rebooted it. That seems to have things back to normal. Now have good battery life again, and the "Mail background" contribution is back to less than 10% where it used to be.

If you haven't done so yet, just try turning the phone off and then back on before giving up on iOS 12.

Yes your contacts, email, notes, passwords and messages are backed up to iCloud. Whatsapp has its own cloud service. You can restore your chats by typing in your phone number. Manually backup your photos.

Restore using iTunes. Click on restore, not update! After the restore has completed, on your phone, it'll ask to sign into iCloud. Sign in. After that it'll ask to restore from an iTunes backup, restore from your iCloud backup or set up as new. Select set up as new. Don't worry. Your contacts, messages, emails etc will be back on your phone in a few minutes. You won't have any apps though.
