I’m in the same dilemma kind of, but happy with the 16P now.
I've got a 16 Pro on the way from Xfinity, really glad to read these comments about good battery life. By the way guys, I wanted to charge and listen to music (wired not bluetooth) in my vehicle, will that be a USB A (car side) to USB C cable like this? Thank you for any replies.

When my battery drops rapidly I plug it into the charger and perform a hard reset. This usually solves the problem for me.
FWIW I returned my 16PM but on average I was ending the day with around 25-30% more battery than the 16P. I'm ending with 10-15% more battery life at the end of the day than the 14P I replaced it with (with 100% battery capacity).

I am using a Galaxy Fold 6 and iPhone 16 Pro simultaneously with the 80 % cap limit enabled on both and I have noticed that I finish the day roughly at the same percentage, which is kind of interesting because the Fold has to run 3 screens and isn't really known for it's battery.
The iPhone 16 Pro's battery life has definitely improved this year it's closer than ever to the Max!
Officially the 16P is very close to the 15 PM battery life, but don’t know… not for the moment until they fix some drain culprits.
Interesting! How do you utilize two phones in your life? I think Samsung are great phones, but intrigued to know what you do with two different operating systems and phones.
It works really well actually. I transitioned to using Google services (Photos, Calendar, Contacts) so both are always in sync. In Germany we also have something called "Multi SIM", so I can have the same number on up to 7 devices sharing the same plan. When I get a call, both phones ring and the other one stops as soon I pick up. Both are basically a clone of one another. I also use a second sim on the iPhone for work
No the 16pro has about 10-15% more capacity than the 14P in my own use. I did not use the 14P on iOS 18 very long so it could have been skewed. But it did get a fresh battery not too long before I got the 16pro. My weekday usage is pretty consistent and after a month or so I'm usually confident in the kind of battery life I'm seeing as normal.
It’s difficult to compare as I only charge the 16 pro to 80%. Whereas the 14 PM was always charged to 100%.
That cable will work in the car. I use an Amazon Basics usb-a to usb-c for wired carplay and it works just fine.

Ever since iOS 18.1, the battery life has gone downhill. iPhone 16 Pro cannot make it to 10 hours SOT anymore, it's more like 5-6 hours SOT.
I don’t know what happened but since yesterday my 16 Pro is super hot and battery is draining super fast even after multiple restarts and hard restarts. Must be an iOS 18.1 issue. Ugh.
I’ve been experiencing similar issues with my phone since Tuesday. It gets hot and the battery drains quickly. I haven’t had any problems like this before the update to 18.1.
I’ve just got a 16 pro, which I’ve had for 5 days now, and I’ve noticed INSANE battery drainage.
The phone came, and I updated to iOS 18.1. The phone seems to be losing 1% every few minutes or so, with just browsing. The issue occurs on both WiFi and 5G (which is expected to perform worse). However, coming from the 15 Pro Max (wanted a smaller screen), which I did run on 18.0 for some days and was perfectly fine, I expected roughly the same, maybe slightly less battery life, but this is ridiculous. The phone seems to randomly also lose 1-2% upon using the camera.
Just by typing this message, I lost 2% (admittedly on 5G but with full coverage and nothing running in the background). Is this an iOS issue, something with the phone, or the battery is just bad? 😐
The phone doesn’t mention anything about indexing.

Why the F is my 16 Pro so hot? Even coming thru the silicone case like super hot and battery draining fast. About to throw it out the window.
I have changed it 3 times in total and this is my 4th phone. All of them had cosmetic defects. There is no cosmetic defect in this phone, but the battery drains very quickly and the sound is booming when sending messages on WhatsApp. I do not notice it while watching videos or talking on the phone. Has anyone encountered such a problem?(16pro battery production date is July)

The same here. My average is:
- I use the phone between 8:00 AM and 9:00 PM
- During this time I can achieve 6h screen time and still have like 20-25% battery
- to have 10h screen time I would have to use the phone constantly for 10h and web browsing only or maybe tiktok scrolling
In total, I can make it through the day but no chances to have like 10 or 11h screen time and still have 20% battery backup.
I spoke with Apple (in my country we don't have Apple Store only resellers) about this issue(?) and I bought my unit directly from Apple Online Store (official, local branch). They told me that this usage seems to be normal even decent and the SoT may vary depending on apps we use. It is hard to compare. At the same time they performed diagnosis which returned all results 100% correct, no errors. As they stated, this diagnosis is enough to decide if the phone should be diagnosed further or not.
What I have done so far:
- clean 18.1 installation via DFU and Finder
- did not restore the backup - I logged in only with my iCloud account. Rest of the apps I have restored manually
- AoD, 5G, background apps refresh, raise to wake up: turned off
- I use WiFi 90% of the day
- Phone calls via WiFi activated
Attached my stats.
At the same time, before 16 Pro, I had 16 Pro Max for 7 days and the battery life wasn't impressive as well. While I was seeing peans about the battery, 18h SoT and stuff like that, my phone had 4h screen time within 50% battery usage. So I returned the phone.
Both units were manufactured in September 2024. 16 Pro Max was from T-Mobile official store and 16 Pro is from Apple. 16 Pro Max was working under 18.0.1 and 16 Pro is working under 18.1.
I have three options:
- to return this unit and try with another one which gives me no warranty that it will solve this problem(?).
- give it to the service point for the in-depth investigation but it will take 3-5 business days. If the phone will be sent to Apple in Prague, then it will take up to 8 business days which, in both scenarios, will close my 14 days return policy window.
- To keep this unit and accept that it works this way. I have never been in the situation when I would need phone to be charged in the middle of the day I to have no charger or possibility to charge it.
Alternatively we can wait until 18.2 which, as I read on one of the local Apple-related websites, officially introduces apps
I read about users who had replaced their units even 4 times and the battery was behaving the same way as ours.
One more interesting thing:
I connected mu 16 Pro to coconutBattery (device has 5 days now) and iOS shows 85% battery but coconutBattery 82% in Full Charge Capacity.
To be honest, I don't understand it and how to read that: which capacity is real (iOS or coconut)? Why there is a difference?
EDIT: Ok! I understand it now. If I am not mistaken:
Battery design: this is a declarative battery capacity.
Full charge capacity: is a capacity which is the battery capacity resulting from the manufacturing process because it's probably impossible for every battery to be accurate to 1 mAh
So I could assume that iOS reads the current charge and calculates it based on the declarative (not actual) battery manufacturer capacity). So the calculation is: 2979 mAh left : 3544 mAh declared/hardcoded in the system: ~85% which shows my iPhone. If consumption was calculated in terms of the real, chemical battery capacity of 3627 mAh, iOS would indicate ~82-83% battery.
However, comparing what iOS shows (85% - which, again, is also more of an estimate without decimals) and calculating against the claimed capacity (82.1%) the difference is up to 2.9% which does not seem like a huge difference.
The conclusion is that my battery capacity seems to be legit. And I don't believe that the difference of 2% in battery capacity could cause 4h screen time difference.
