I am running the July Security Update and July Google Play System Update. 

Your mileage may vary, but recently, I am seeing significant battery drain. 

In a matter of minutes, the phone went from 92 to 86. I'm not playing a YouTube video or anything. I was doing a song search on Spotify and then just checking regular stuff. 

Cleared patrician cache and rebooted. 

No rogue apps detected. 

Again, your mileage will vary and some will say July is the best patch yet.

Woopd like feedback and options from those experiencing battery drain and what they have done.

Oneui8 is coming. Here's to hoping!

I just got this phone and the amount of bugs is frustrating. Can't get notifications, can't turn off some if the apps draining the battery, and can't remove permissions in some apps. That being said, I put it in airplane mode when connected to wifi and that keeps the battery pretty good. Also helps with data

Yes, you can still run Bluetooth and WiFi in airplane mode. A work around, but your case sounds more frustrating than mine. If your s24U is inter warranty you might consider returning for another one.

Having the same issue ever since that update went live. Does your phone completely die at 45%?

I just replied in your other post.

No, mine does not die at 45%.
If it gets down below 10%, which I very rarely am not next to a charger to avoid this, it is a rapid descent to 5% and then completely drained.
You may want to Google your issue. That 45% stopping point sounds familiar from other posts. Might be some fixes out there.

Received a notification that said Google Messages won't work unless you update to the latest Google Play Services. More about it with the link below.

Maybe this will help the battery drain? 🤠

Here's a question...

Which setting do you notice better battery life with, Adaptive battery on or off?

Okay, follow up observations and action steps ahead...

- When charging to 95%, the battery would often drop rapidly in the first 10% of usage—even during idle periods.

- This led to a perception of inefficiency, especially when the phone was not actively used but still receiving notifications.

- Samsung’s adaptive battery algorithm seemed to treat the first 10% as expendable, which raised questions about whether partial charging was actually undermining performance.

**The Solution**

To test this, I began charging to 100% and immediately noticed:

- Improved idle efficiency: Battery drain slowed significantly, even with notifications and background processes active.

- More stable early discharge: The first 10% held longer, suggesting better voltage regulation and system optimization.

- Perceived algorithmic shift: Samsung’s power management may interpret a full charge cycle as a cue to optimize background activity more aggressively.

The Bixby Routine

To preserve battery longevity while still benefiting from full-cycle efficiency, I created a Bixby Routine for wireless charging overnight.

1. Activates during wireless charging, specifically between 7:00 pm and 6:00 am everyday. Wide time range of I go to bed early for some reason.

2. Enables Fast Wireless Charging, Auto Sync, Battery Protection (Maximum), and Always On Display. These are turned off unless charging to save battery. AOD is set to tap to display.

3. Uses “End Routine” logic to trigger a set of actions once charging concludes—ensuring the phone does not remain in a high-power state unnecessarily.

This routine allows for full charging to 100% while maintaining control over background processes and display behavior. It avoids prolonged trickle charging and supports a more intentional overnight charging protocol.

**Why This May Work**

- Battery Calibration: Charging to 100% occasionally helps recalibrate the battery meter, improving accuracy and perceived efficiency.

- Voltage Stabilization: The final 5% of charging is slower and more controlled, which may reduce heat and improve short-term performance.

- Adaptive Optimization: Samsung’s One UI may optimize background processes more effectively when a full charge cycle is detected.

**Takeaway**

This is not just a tech tweak—it is a protocol. By combining full-cycle charging with smart automation, we can possibly:

- Preserve battery health
- Improve short-term efficiency
- Document and refine usage patterns for long-term benefit

If you are seeing similar behavior, consider testing a full charge with a Bixby Routine to disconnect power or manage system behavior at 100%. The results may surprise you.

Screenshot attached for reference.

BTW: It looks like Samsung removed Adaptive Battery Charging. I only see Basic and Maximum as options. The above is a work around to create your own schedule for overnight charging, provided you have a fairly consistent sleep schedule.

Hope this helps. 1754678627356.jpg
