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.
