Question Official battery life thread

yeah but this is chemical science, and it applies on all li-ion batteries since it exist.
Not because Samsung give this option for nerds, that you have to use it.

Yeah, I totally agree... just thought it was funny. Sort of like how some keep old phone screen protectors on, all peeling and scratched, in the name of keeping the screen preserved while they can barely see through the protector. :-D

Tried it yesterday but it didn't work. Routine was running, as I've checked, but it didn't turn off Protect Battery setting after set time. Any idea why? Was this because Night/Sleep Mode was running during Routine?

Don't know i never used night/sleep mode. Can you show your routine?

Here it is:

Additional note, I was using wireless slow charges, not sure if that matters.

For me I find using the phone with mobile data delivers better battery life than WiFi, I charge my phone to 100% for bedtime and 7 hours later I have lost 3-5% on WiFi but 1-2% on mobile data, using gsam battery monitor I see on WiFi the NLP collector wakelock and another NLP wakelock has my phone awake over 10mins but on mobile data these wakelocks are no more than 10 seconds, so must be bug in the WiFi that keeps my phone awake, hopefully a software update will fix this

Is it possible with Wifi on that some apps may be doing some background work because they are only allowed to do so if connected to Wifi?

Should work, try without this night sleep maybe. I also use wireless charger with turned off fast wireless charging.

Hi

I want to charge my batery slowly at night is possible to set this slow charg like oppo or not ?

Is possible to set slow charge, and limit max charge to 85%.

Also, if you play with Samsung routines, you can create a routine that do what you want (like enable 100% charge 30 minutes before your alarm)

Thanks you

it is possible using routines. Time period - battery - slow charging enabled.

Some may sell that this is fake. I say - fine, I am happy with my "good old Nokia" .
You can find my other posts about the settings I applied.

Hi all, how many of us here use adaptive battery? Does it really save any battery? The jury is still out on this feature in different forums. I just wanted to check how everyone's faring here with or without this option.

I disabled it a few weeks ago. Do not see much of a difference. Maybe a slight increase in standby, but that could be placebo.

meta services drain battery during the night (10pm~6am)，anyway to stop this?

Same here..the battery life seems to be better without the adaptive battery.

Yes, get rid of facebook and the other garbage associated with it. But if you practically live in facebook, then live with this battery drain...it's only going to get worse.

 

[donkeyman1234]

I think I will use daily routine to stop facebook working during the night.

It's not going to help because facebook's apps are known to run in the background no matter what. The only way out of it is to delete the apps completely via adb.

The amazing battery life has a lot to do with the display too. It is a hugely more efficient panel.

That actually sounds believable because at first days of setting everything up I was actually surprised to see how much screen-on-time was the phone able to take (over 5 hours SOT with quite heavy overall activity and just about 60i(sh) % of battery consumed to that). Even on these days the estimate for full charge was 3 days, while it is now in about 4 days (and all that without any connectivity functionalities switched off).

Old S20+ was barely able to reach half of that at best. Considering that S20+ had 4 Ah battery and S23 Ultra has 5 Ah we have very significant advancement in overall efficiency.

Well there's no doubt that

I completely agree that there are certainly many ways to "save" battery health, and how you describe the above (in quite a wide variety of scenarios and not even quoting Samsung devices in a comparative way) is probably not the most optimal way to do it either - that is, you could probably save even more, but inconvenience/impracticality would start becoming an issue. However, the question is whether it's worth changing approaches at all specifically for Samsung devices.

I know for Electric Cars, some batteries are much better at reducing degradation than others. Generally, there have been significant improvements all around as battery tech improves. The Blade battery for example is so good at reducing degradation that the manufacturer/sales companies don't bother suggesting/recommending their customers charge to 85-90% only like many other brands do.

I can't speak for the iPhone or for laptops/tablets (also wouldn't surprise me if you're using old models which have older anti-degradation battery tech etc), but I can share my real-world experience with having owned 3 previous Samsung phones (prior to S23 Ultra). With the S7 (owned for 2-years) and S9+ (owned for 3-years), I observed what I'd subjectively say as mild degradation by charging to 100% overnight (and thus leaving it "on charge" at 100% for at least 4-6 hours a day). I use the term "mild degradation" as it did not impact my everyday use of the phone at all in terms of battery life. This is what is actually important, rather than measuring some number with some app which may or may not be accurate.

With the S21 Ultra (owned for 2-years), I actually stopped leaving the phone charging overnight, but always topped up to 100% in the evenings (before bedtime) and then disconnected the charger once it hit 100%. That would be the only period of time I'd charge the phone on the vast majority of days. When the phone was brand new, the estimated battery life reported by Device Care ("A full charge will last about") was 2 days and 2 hours. 2-years later, it remains the same. However, more importantly (as referenced above), I also noticed no change in everyday use of the phone in terms of battery life.

Anyway, it's possible that Samsung battery tech is better than (older) iPhone models and other laptops. Who knows really. But anyway, I still don't see any compelling reason to only charge to 85% for my specific use case, but it's interesting to read about other people's experiences.

There's one thing that is actually used in electric cars and can be used anywhere else where lithium batteries are used - some of battery capacity is hidden from the user making it a "buffer". This way user can see degradation starting only when this buffer is exhausted i.e. the actual battery capacity decreases to the "net level" which is made available/advertised to user.

There's of course another issue as well which can not be hidden - degradation causes the internal resistance of battery to increase which leads to quicker drain under heavy load while behaviour under standby might not seem to be affected (yet).

Anyways one of the biggest factors affecting battery degradation is still the temperature. I usually use the routine that switches charging over to "slow" (fast charging OFF) based on charge level while charging and reverts the change afterwards.
