iOS 14.7 Battery Drain

I wish the same thing, because I have experienced the most efficient battery life of Iphone 12 lineups on IOS 14.3

now i am on IOS 14.7.1, but overheating and inefficient battery life issue still persist.

It's so frustating.

Thanks for the help and suggestions, whizkid11! I did a restart directly after. No help. I only noticed because I use my phone for very specific things and it's not cluttered. I did find a 14.7 download and have it as a backup if needed. I'm going to continue to monitor progress. I'm hopeful that Apple will address this because it's SO remarkably different. I will continue to test ideas and post progress if any. :)

Also, I took screenshots of the battery life (in settings) for a 2 hour period. What was used and how it went down so quickly. From 5am-8am. 5am-6am=fine. 6am-7am=drained 50%. 7am-8am=fine. The only thing running was Netflix. Interesting :)

Same with me while studying for physical therapy licensure exam. Lasted super long with much heavier, intensive video use along with heavy graphics in anatomy apps. Good luck on the Bar if you haven't taken it yet! Great accomplishment!!

I have to keep mine on the charger 24/7 now and keep it on low battery mode! They have not mentioned anything about a battery issue. They have not even attempted to address or fix the issue on the battery drain! They are really trying to loose millions of people by not addressing or fixing the issue!

Thank you. Same to you!

Just to update. I’m at 50% at 4pm with intermittent use since 10:30am. I never got down to 50% even at bedtime running 14.3. I’d say it’s comical but it really ****** me off.

Thank you for this good, solid advice. Perhaps I've jumped the gun. - I'll wait a few days and see if it's sorted. I didn't know how updates were administered and how different generations could react to said update. I'll give it some time, as suggested. Question - if battery problems continue, are there next steps? Thx. :)

I haven't every experienced a battery drain except the first hours or day after an update, so I don't have any personal experience to share. Some of the things I've read on line include misbehaving apps (either benign or malicious), or something that gets messed up in memory for the operating system, so only after a day would I probably next try a power down, wait 60 seconds, then power back up. If the drain continues, check settings to see if it can identify an app that's drawing a lot. Perhaps there's an app that somehow conflicts with the new iOS version.

Something else that I do is prior to an iOS update is to update all my apps, and then shortly after the update also update all my apps.

There's probably more suggestions on troubleshooting online, or the next thing would be to check with Apple.

Side note -- I wouldn't rule out a problem in iOS, but being a software profession for the past 36 years, if it was purely an iOS problem, even if only on some iPhone models, I'd expect to see a lot more people with problems. So my personal feeling is that it's more complicated than just the OS.

I updated my device (iphone 12) from IOS 14.3 to 14.4 in early February.

In 2 days of usage, with similar activities, I realized that my device battery was draining faster than usual.

I gave it more time, because some people said it could be part of re-indexing process.

unfortunately, the issue still persist and it's already too late for me because apple no longer signs IOS 14.3

I followed every IOS 14 update release, with the hope that latest IOS update could resolved it.

however, it's just stay the same (sometime even worse).

my bro (he's using 12 pro max, frequently for playing game) noticed the issue more clearly.

many 12 pro max reporting that the battery life is great on their device no battery drain and heating issue shown after running on ios 14.7.1? i can't understand so why the performance and battery issue are so differ?

My battery goes from 95 to 30 percent in in a few hours! I have reset my phone that helped so it stays on in the day but I have to keep it on the charger it takes 12 hrs to charge not sure why but happened after the update! I have my phone to 100 percent now at 11:45 pm and by 5 am it’s dead and has not been touched nothing running! My phone is not dependable till this is resolved.

I am one of the first writers of the problem. It’s been more than a week and the problem still persists… Apple owes us a solution or a new battery… Why don’t they let me go back to 14.3… that’s ridiculous…

this is ridiculous i’ve had the phone for 6 months and always got a full days use with a full battery and since i updated if a couple days ago it drains so fast and i have to charge it multiple times a day. I’m seriously considering switching to android… the only reason i even updated it was because of the stupid dimming issue that started two weeks ago out of nowhere and was told updating would help but guess what? it didn’t help ANYTHING and now the battery is screwed. Apple is trash now

Do you have a specify way you charge your phone to keep battery health that high? Like do you ever let it get lower than 20% and higher than 80% ? I ask because so many people say that’s how you keep the battery healthy over a year.

Im not only having issues with battery drain, my phone has been overheating just by looking at some videos and playing games using LTE. It’s gets so hot it feels like it’s gonna blow up. Stupid apple. I just got my 12 pro max two months ago and now this.
