iPhone SE battery drains quickly

Hello,

My iPhone SE 2020 battery is giving me almost 2 hours of on-screen plus 30 minutes of off-screen time. Apple support thinks that the battery is doing just fine, can anyone please help me figure out what's wrong here?

1 - battery health is 90%

2 - no app seems to drain most of the power (even if some app is draining more than other, I am getting 2 hours 30 minutes of background+on-screen time)

3 - auto brightness is on, and I usually use phone indoors so screen brightness is always very low

First thing is to test battery for self-discharge. Health is only an indication of capacity and not actual chemical health.

There also may be apps that are inherently incompatible with the new iOS

Start by removing any VPN or security apps. Apart from being totally unnecessary they are also a strong contender.

Many mainstream apps need an urgent update, so go to App Store and scan through your apps for those that need updating.

While there, uninstall any apps you haven't used for some time. They are unnecessary update burden.

Check Settings, Privacy, Location services and make sure none of them say Always.

Check the battery usage chart in battery settings for any obvious bad apps but not every background process is shown.

Any streaming apps or apps that can run with phone closed, or Clocks that hold the phone unlocked, always force close them afterwards, despite the accepted wisdom not to.

Only after all that do you need to do the simple stuff advised in
