Over the past 2 months, my iPhone Air has been running noticeably warmer (almost uncomfortably warm) and battery life has worsened significantly, despite no changes to my usage, apps, or charging habits.

Previously, I could easily make it through the day and charge before bed. Now I’m often reaching for a charger around 18:00.

I took the phone to the Apple Store and Genius Bar diagnostics showed no hardware issues.

The only thing that has changed is that battery health has dropped from 100% to 97% during the same period.

A typical day: I start around 06:30 and am often down to ~35% by 18:00. Before this started, I’d have substantially more battery remaining.

Has anyone else experienced increased heat and battery drain recently? Could this be related to a recent iOS update, or is a 3% battery health drop enough to explain both symptoms?

Any insights would be appreciated. Thanks.

a battery health drop of 3% over a two month period would be very unusual, if accurate.

i have an Air.
i set my max charge to be 80% and am using it very heavily throughout the day, and have around 40% at 19:00.
health is 100%, with 152 cycles.

my Air has gotten slightly warm maybe around two times over the past several weeks, which i attribute to my using some very heavy AI process Fitness-Health apps.

So this was my experience up until 2 months ago. The genius at Apple Store said that it was most probably software related but I don’t consider myself a heavy user. Through the batter usage stats safari seems to be the culprit. Otherwise I have done all the usual stuff. Turned off location for most apps, background refresh etc.

I will look into coconut battery, thanks for the tip
 
What version of iOS are you running? My Air is on 26.5.1 and it’s not great! They just can’t seem to sort it out, thankfully iOS 27 is showing early signs of being great!

Hopefully iOS 26.5.2 will be released soon and then 26.6 is in the pipeline bringing more stability.

Yeah I am also on the latest build 26.5.1. I have been eyeing the beta for this exact reason.

I'm on the same 26.5.1 and my Air battery life is nothing short of outstanding so I'm not sure the version is to blame!
