I updated my phone last night and noticed something strange. By 5 PM, my phone, which is usually at 80%, was down to 38%. It’s losing a percentage every few minutes when I’m using it. This never happened before. Does anyone know how to fix it? I’m using Verizon.
You could try clearing the system cache. Also, check if a specific app is causing the issue in the settings. You might want to recalibrate the battery too and see if it makes a difference.

Where exactly do I find the system cache?
Thanks for the suggestion. I’ll look into the settings too.
@Sam
By the way, is this kind of issue normal after an update? I’ve never had this happen before.
@Sam
To clear the cache, turn off your phone. Then, press and hold the Side key and Volume Up button. When the phone powers on, release the Side key but keep holding Volume Up until the Recovery Mode appears. Use the volume buttons to navigate to ‘Wipe cache partition’ and select it with the power button.

Thanks for the steps! Just to confirm, will this log me out of all my apps? I checked online and it doesn’t seem like it will. Also, are there any downsides to doing this?

No, it’s perfectly safe. The only thing it might do is reset the battery calibration, and even that’s not guaranteed. It won’t log you out of apps or affect your accounts. I’ve done it a few times myself and didn’t notice any issues. Some people even recommend doing it after every update to help with battery life.
@Kieran
The cache partition mostly holds temporary files, like logs or updates in progress. It’s not going to mess with your personal data.

Exactly. Just temporary files. Nothing you’ll miss.
It’s actually normal for battery life to drop right after an update. Here’s why: when the update first installs, apps aren’t fully optimized yet. Android will optimize them later, especially when the phone is idle and charging. This process improves efficiency over time.

But in general, the more processes your phone is handling, the faster it’ll drain the battery.
