S25u battery

[dany1219]

Hi all. I just received my new S25 ultra few days ago, the phone looks great but my main worries is about battery . I set it to charge till 85% , today when I took it from charge from 85 % goes to 77% within 1hour ish without using almost at all, only chat little bith through whatsapp. So far I think a full charge battery from 85% it runs about 20 hours for me. 

My question is how long takes a full charge for you using normal day? Is there any other settings tricks? Or the phone is faulty, but on settings on battery health's shows 100%. Or my expectation regarding battery was too high.

Many thanks for answers.

Yeah but the learning cycle of mines ended between 2 days .. and I'm only getting around 7h of screen on time... Will it still adjust

[lminvti]

Yes, anywhere from 1 to 2 weeks. It will adjust. Please post after 2 weeks time or your results, should be day and night difference 😊

But the learning pattern disappeared after 2 or 3 days ... Is that normal and should I be charging it to 100% the first week before changing it to 80%

Just charge it to 100 percent the first startup, and then turn on battery protection with maximum setting and adjust the percentage to 85/90. And charge it when it comes down to 21 percent. You can always tweak the numbers to get more charge, but wouldn't go beyond 95 percent. I will have mine set on maximum and 85/90 percent. And make sure not to drop under 20 percent charge. 

And it's normal for it to get hot the first times you charge it. A part of the brake in period.

Mine is fine

I have the base S25.  Same(ish) issue.  I have battery set to charge to 100%.  In the first hour or two it will fall all the way to 80s with hardly any usage.  Seems to stabilize after the overnight charge cycle (as in it plummets first off charger in the morning, but once I recharge, then it can get to 100% and then takes a much more normal fall off rate).  Hoping "learning" helps considerably.  Don't see any apps that are disproportionately using battery.

Update:
After 21 days since I have the new phone the battery can't last more than 24 hours if not using much, if I use the phone 12 hours. I think to return the phone I'm really disappointed 😞

Have you all the latest updates and adjustet your settings discussed in this tread?

I just received now an update...and the settings are all there, I checked everything. I will keep monitoring as I'm abroad for a week, but if still no luck I think to contact someone from Samsung.
