How to fix battery drain in ios 16.1.1 Or How to downgrade 16.0.3 [ ios 16.0.3 was very good]

Greetings ratan292,

For help getting the most from your iPhone battery, follow the guidance found here:

Batteries - Maximizing Performance - Apple

"Optimize your settings.

There are two simple ways you can preserve battery life — no matter how you use your device: adjust your screen brightness and use Wi‑Fi.

Dim the screen or turn on Auto-Brightness to extend battery life.

• To dim, open Control Center and drag the Brightness slider to the bottom.
• Auto-Brightness adjusts your screen to lighting conditions automatically. To activate it, go to Settings > Accessibility. Tap Display & Text Size, then turn on Auto-Brightness.

When you use your device to access data, a Wi‑Fi connection uses less power than a cellular network — so keep Wi‑Fi on at all times. To turn on Wi‑Fi, go to Settings > Wi‑Fi to access a Wi‑Fi network."

Take care.

Thanks to say always the same useless thing, we’re just want to report that last update is draining faster the battery, so say at least that you’re keeping the report and say that you will try to fix it with the new update…..

I’ve had the same problem. Almost two weeks since updating and my battery still drains. My phone is only a few months old and it used to be great on battery life. I’ve even followed all these optimization tips and they don’t help any. My older phone lasts longer.
