Since iOS 16 was released, users have been complaining about how the update has destroyed their iPhone’s battery life. It is normal for your battery life to be a bit lower after a software update. But something different seems to be going on this time around.
When you update your iPhone to a new version of iOS, there might be a temporary decrease in battery life. This is because iOS is doing things in the background like reindexing files, photos, apps, and more. Once all of the background reindexing is complete, the decrease in battery life usually stops.
After a new software version is released, many people complain about the battery life. This is because the software needs to do a lot of work in the background, which uses up more battery. But usually, after all of that work is done, people stop complaining.
However, this year there have been more complaints than usual. People are saying that their battery life has decreased significantly since installing iOS 16 two weeks ago. And many people think that Apple purposely reduced battery life on older iPhones to drive iPhone 14 sales.
Users have been voicing their concerns on reditt:
My battery drain is hugely more than i usually had. I work in the office and dont use my 13 PM that much during the day, nothing has changed in my behaviour. On iOS 15 I mostly came home with between 85% – 90% left. With iOS 16 its between 65% – 75%. That’s in my opinion quite A LOT when almost not using my phone.
Battery on 13 pro max drains like crazy. It went from 11-12hrs SOT to just 7hrs and it lags like hell when I do facetime or PiP, it just lags in general. I do know it takes a few days for the phone to be normal again but it’s already been almost a week. I’m contemplating on going back to 15.7 but I might need some opinions first.
Apple has not yet commented on the battery life concerns from people who have upgraded to iOS 16. The company released its latest update without any mention of battery life improvements.
Overall, it seems that battery life has decreased for many people after upgrading to iOS 16. So, hopefully Apple will release a fix soon.
Have you experienced a decrease in battery life after installing iOS 16?
Comment below to let us know.

Agreed! Since IOS 16 was installed Battery life is being sucked away rapidly.
I have a question, really. I have been seeing all this stuff regarding iOS 16 on the internet. I have an iPad & I updated a couple of weeks ago to iOS 15.7 & I haven’t gotten any info on an update to iOS 16. Is that update only for iPhones?
Yes it drains very fast.
When I get up in the morning I take my phone off the charger and it’s at 100%. Today, I never used it at all and after three hours of being taken off the charger it was down to 1%. What is going on?! I have an 8 so I have been noticing that I need to charge my phone every 3-4 hours since I use it a lot. But since downloading IOS16, the battery just runs out without even using the phone at all. I thought Apple already lost a lawsuit for purposely making batteries run down on older models to force people into buying new phones. Time for a new lawsuit!
Yes so I had iPhone X and yes the battery seemed to drain faster after 16 updates. I got the new 14 iPhone and it is a little better but it seems that something is constantly running on it.
YES I have noticed that! It seems like I
Am constantly needing to plug my phone on the charger. I like the upgrades but don’t like having to constantly charge’
Yup, big time. Hopefully it will get better. Still love my iPhone 11.
Yes my iPhone 11 battery is discharging more quickly since updating to iOS 16.
Yes, my battery life isn’t what it was before
IOS16. I have a 11 pro max
My battery life has definitely diminished on my Apple 11 which isn’t a year old. This has happened since the upgrade. It’s down by about 35%.
My iphone SE and my apple watch 3 are running out of battery every day after a few hours. Help. It’s got to be ios 16. What do I do?
Yes. My daily battery life has diminished severely. I charge it to 100% everyday. I have not changed how much I use my iPhone XR. Usually I had 30-40% by evening. Now it’s 10-20%. I hope Apple hears all of us.
I have 12 pro max and my battery has been going down super fast
I have noticed a decrease of battery life. I hope the download comes soon to fix it. Thank you for letting me know why
I am experiencing significant battery drain with 16…
Thanks for letting me know why my 8 is running out of battery real fast now. Hope Apple fixes this soon.
I normally have Bluetooth turned off, if I’m not using it and my screen brightness down below 25%, but since I downloaded iOS16, battery level drops rapidly, even after updating to iOS16.2!
Oh, yes…I find that I’m having to recharge more frequently since the update!…glad to know what the issue is and hopeful for a quick fix from Apple!
