IphonePM received on launch day, playing with it from 5:30 AM until about 9 PM daily, using the 80% charge option. Have used 40 to 45% and 5 battery cycles.
 
15 PM release day - 7 cycles so far. Not using the 80% option.

I think it lasts longer than my 14 PM, but not by much.
 
Base model 15.

Charged to 98% last night, unplugged it and turned it off. Woke up at 7:30am, powered on. It's now almost 5:30 and I'm at 66%. I've used it quite a bit today too. Pretty impressed. If the regular 15 is this good, the Plus users must be over the moon. I just got 10 hours usage on 33%. I could almost get two full days out of this thing if I powered off at night.

Don't want to look at cycles though. It's way too early in the game for me to even worry about that kinda stuff.
 
Launch Day, 6 cycles, do not use the 80%. Take off charger at 5:30 am average 6.5-7.5 of SOT and usually go to bed at 9 with 40% left . Been loving it so far
 
4 cycles, was at 0, got it on Monday 3 days after launch. Stopping at 80%
 
15 Pro since Monday after launch (25.september). 10 cycles. And I'm trying as best as I can to use my Galaxy S23 so I am not killing the battery health to early.
Although... I'm about to give up and just use it as I want, and then I rather take the cost of changing battery if it falls to low. It's too stupid to buy such and expensive phone and not using it because you're afraid of those cycle counts...
 
My launch day had 3 cycles before returning. It was the 512 gb and the battery life was horrible. Friday i picked up the 1tb and battery life is way much better. Currently used 1 cycle
 
The past few days, my 15 Pro has been great and lasting all day no problem. The first few days were another story. A lot of people just freaked out and returned or exchanged for a Pro Max without giving it a shot. The app and OS updates will only make it better over time.
 
Launch day 15 PM. At 5 cycles. Tried 100% the first 5 days where it was 3 cycles. ~3 days at 80% where it was 2 more cycles. Sticking to 100% from here on as I was always at ~25% at the end of the day when charging to 80%.
