Battery Life Estimate

[userlQcCM1wRc8]

Battery life is good but not 4 days 19 hours good. Actual battery life even with heavy usage, 8 hours SOT, texting, calling, videos, etc. is about a day (24 hours or so). 

Everyone's usage and battery life will vary and I am pleased with mine. 

It is the battery estimate that is so completely random, anywhere from 1 day (most true to actual), 2 days, 20 hours, 16 hours, and so forth after a full charge. 

4 days and 19 hours really is laughable. 

All this to say, Samsung really needs to get a handle on the battery life estimate as it is all over the place. 

In 20 minutes of usage SOT and 9 minutes of screen off time the phone used 1% from 100% to 99% and the estimate is 3 days 1 hour. 

Also, the battery report states 2% of usage.

Off topic but I haven't seen Nova Launcher in a minute. Just preference or do you use for something the stock launcher can't do yet?

I thought someone might pick up on Nova Launcher in my battery stats. Nova was purchased by another company but the core functionality not only remains, but has been improved upon over the last year or so.
Short answer to your question, Samsung's OneUI also continues to improve and expand functionality.

Nova is still leaps ahead though and in too many ways to list.
It is really excellent. Yes, it costs me a tiny bit of battery but is very self contained for a third party launcher. The benefits are worth it to me.
That said, it does appear that the new owners have a stake in monetizing the launcher beyond a one time purchase. This would also mean further hooks into privacy. At that point I would probably move back to MS Launcher which is also more advanced than OneUI but still very solid.

I still use nava launcher myself. 🙂

Same here. Nova until privacy concerns are unacceptable.

So how have you kept your battery this healthy? Do you use fast charge? I got my S24U when it launched and it barely lasts 10 hours.

I've considered a new battery. I'm charging twice a day to maintain.

[userlQcCM1wRc8]

Fast charge, but mostly wireless.
I use Bixby Routines so it charges to 85 percent overnight, then tops up to 100 percent about an hour before I get up. The big benefit of doing it this way is that the battery does not sit at max voltage for long periods, which is one of the main things that ages lithium‑ion cells.

I also keep the background environment clean. I removed bloat apps and anything that likes to run services in the background. That alone prevents random heat spikes and runaway processes, which quietly wear the battery down over time.

WiFi, LTE, and Bluetooth stay on unless I am sleeping, and GPS is only allowed for selected apps when needed. Bixby Routines handles all of that automatically. I stay in the standard profile and use power saving all the time. The processor is more than fast enough, and the efficiency gain is noticeable.

Fast charging is fine as long as the phone stays cool and you are not leaving it at 100 percent for hours. With these habits, my S24 Ultra still behaves like a low‑wear battery: smooth discharge curve, low idle drain, and no thermal surprises. I also bought mine at launch and it is still the original battery. If Samsung exposed battery health, I would guess it is around ninety percent or better.

I consistently get a full day or more with heavy usage.

Power saving maximum or standard? I have to have mine set to maximum to get a day

Battery life has been mixed for me. Some days its like it was on one ui 8 with a solid day and others I need to charge 3 times a day 😳 also get random overheating with moderate use and random unexpected shut downs
