Indexing is a thing but looking at some of the graphs you guys have shared, the drain is rather drastic. Whenever I switched iPhones, the first couple of days of indexing don’t drain much. The gradient is rather gradual.

In my opinion, I think it’s part of Apple’s plan to reduce/increase battery life every other year. Before I get called out for speculation and being a conspiracy theorist, here’s what I can back up with.

The iPhone 11 Pro/Pro Max had tremendous battery life when they first came out. Best battery life ever at that point. Sadly the 12 Pro/Pro Max were downgrades in that aspect. A year later, the 13 Pro/Pro Max had major improvements in battery life. And this year it seems like we are following the cycle.
You're totally right

11 pro - good
12 pro - bad
13 pro - good
14 pro - bad

14 pro battery is nothing special, the only real downside to this phone which in every other aspect is close to perfect. It’s marginally better than my 12 with 88% battery health and this is with AOD mainly off. Though admittedly my 12 was stuck on iOS 14 something. Haven’t upgraded to 16.1.1 yet so perhaps that’ll help.
 
This is the battery graph for my 14 PM.

iOS 16.1.1 first 8 days. iOS 16.2 Beta 3 last two days. No discernible improvement.

On average I get around 10% battery use for every hour of screen active time.

Is this typical for most people? Or is my 14 PM an anomaly?

I complained (on here) about the battery on mine but after few softwate updates (currently on the latest beta) it's really settled down.

I'd class myself as a heavy user - at least 5-6hr screen time per day, off charge at 7am, back on around midnight with the phone sitting around 40%
 
Not a heavy user by any means, have turned off AOD, haptic feedback for keyboard; background app refresh is on for certain apps only, but the battery behavior is very inconsistent. One day, i take it off the charger and it's at 100% for almost 4 hours. Other days, take off the charger and battery is down to 97% within an hour with absolutely no usage. Driving me nuts

I said a few months ago that battery life looked really poor on the 14 lineup, and I am sad to see it remains that way. For you to see that I am not all talk, here’s my iPhone Xʀ running iOS 12. It is on Airplane Mode because signal is really bad currently. Light use, Wi-Fi. 3h 10 min of screen-on time with 86% remaining. I’ve gotten more than this, but I reckon this is a decent enough showing. 4 hours 100-30%, like many I’ve seen? Like I said, I get more on a 7-year-old 6s with 63% health on iOS 10…

{FeliApple and I have shared notes before as rare folks that seem to achieve Apple SOT spec}

Curious if you have 24hr battery graph screenshots across the broader range of batt SoC? While 5% batt/hr of SOT seems incredible for a 3yo XR, it’s sometimes hard to extrapolate from such a small sample size. Battery meters lose accuracy over time, some folks reporting their phones shutting down while indicating 40% batt remaining. I recently needed to recalibrate my battery meter and took the opportunity to test the full SoC range (mostly on consistent wifi). Also did the same for my previous phone, a 10yo iPhone 5 wifi streaming YouTube movies. Full rundown tests are the only way be sure.

I’m shocked you can hold Apple spec for years with 100% full charges, as you seem shocked I can with iOS-updates.

I don’t, sorry. I’ll share it with you if I ever have one. I’m a very light user, and the phone drops in standby due to lack of use a lot. I like to track battery life, and tracking a standby-obliterated cycle is useless. So I charge it a lot. Something I haven’t told you is that not only do I not pay attention to any battery conservation techniques, but the phone has spent 90% of its lifetime charged to 80-100%. Not cool for longevity according to every reliable source I’ve found, yet it retains 93% of capacity and achieves Apple spec without a single problem. A 63% health 6s gets flawless battery life with light use as well.

I write down results though. I’ve run it down to 27% once, 13 hours of SOT; to 48%, 9h 6 min; to 70%, 6 hours (once. It is typically a little lower than that, just sharing some highlights). It will occasionally be bad, but that’s due to standby drain. I don’t use it much.

I was disappointed at first and ended up turning off AOD which seemed to help... I rejoined the Public Beta and updated, and I assume initial background indexing of my new Pro Max must have finished as the battery life has improved. I turned AOD and have no problem getting through the day on a single charge. Far better battery life than I ever got on my 12 Pro.
 
Good morning . This is my typical ”battery” day with my IPhone 14 pro.
5h 50m to 7h of screen time . I usually take the phone of charger around 7.30 in the morning, when i m at work or at home the phone is always in wi-fi and the phone is plugged in usb for apple car play for about 25-35 mins every afternoon while i m driving home from work .

At the end of the day i usually have between 15%-35% . For example yesterday i had 35% as you can see in the picture attached.

With the iPhone 13 Pro i had before, the Screen on time with the same exact usage was around 8h-9h.

I usually have everything open apart from Always On screen . I have also done a clean install of 16.1.1.

Definitely the battery usage of my iphone 14 Pro is about 20% worst than my iPhone 13 Pro. Don’t know if this is a iOS problem or my phone is defective. The point is that iphone 14 Pro has definitely worst battery than iphone 13 pro for someone who is using messaging apps like whatapp and social like facebook and Instagram

Did it get any better since Friday?
 
I went from a 12 Pro to a 14 Pro. The first couple of days were horrible, but over time I notice that the 14 Pro has slightly better battery life than the 12 Pro (with 85% battery health) with Always On Display.
 
So my iPhone 14 Pro randomly reset the battery history this morning. Does anyone know why this happens?

Here's my 14 pro after 8 days. The past 5 days have been horrendous but disabled some background refresh and I was mostly on wifi went from 5hours sot to do. This is on 16.2

My iPhone 14 Pro is sill on factory installed 16.0.3, should I update to 16.2? There is some bugs on 16.0.3 but I'm afraid if battery life is worse on 16.2.

Still disappointed about battery life.
It seems some users have the same experience and others has so much better battery life… don’t know why after hours and hours of tests ! What do you think ?
 
Even after all these months the battery hasn’t improved at all. I mean I gotta use Low Power Mode around 16-17h just to make it home… What a stepdown from my 12 Pro.

Is it me or is this underwhelming Granted I don’t use my phone all that much throughout the day but that’s also in part to nurse the battery a little.

I charge overnight and am not interested in micromanaging charging. I have AOD on, widgets on, wallpaper off.
