Reply to comment by dynamojess in Samsung's S23s don't have an answer to Apple's Emergency SOS via Satellite by needlesfox

Samsung actually has a fantastic ultra power saving mode that turns it into essentially a Nokia. battery for days.

It really does keep your phone alive for days. When I had an S20 I tested it out. Ultra power saving, barely touching my phone at all. Lasted 6 days

And they just figured out that if they use a different tape inside the battery (over simplified) they can cut battery drain dramatically

But isn't that only for powered off devices?

TheQuarantinian t1_j6z38xg wrote

Probably not. The electrochemical reaction exists if the phone is on or off, so you will probably see some savings even when using it, it just won't be as obvious

Still it looks like it could be much better. Old phones could last for 2 weeks if not more, in stand by (not turned off - they could receive calls). And they had a much smaller battery and theoretically much less efficient electronics. Seems like the new version is still doing a lot of things in the background. If you wanted to make a true low power stand-by mode for a smartphone it should be lasting weeks, not days. Of course, at least for most phones, you still have the option to just turn it off.

Because old phones were glorified calculators with one or two radios in them, not 8 core computers with 7 inch 4k screens and 20 different sensors and GPS and multiple high powered internet radios in them.

You didn't understand what I said.

What I said is that you could have a power saver state in a modern phone that disables all those sensors, put the processor in a low power state (which is much, much better than those in any old processors), you aren't using your screen because the phone is just standing by not doing anything, and in such a state it should last much longer than an old phone because it would have lower power consumption and a larger battery.

Obviously it's not going to last long if you're using all those features, but it should be able to last long if you aren't. The reason why it doesn't is because even the ultra power saver setting on the phone still leaves things working in the background. Why not have a hyper-super-ultra power saver setting as well that disables them too?

My Galaxy S5 Active, in Ultra Power Save mode would last 12 days according to it's in phone estimate. I was never able to push it in that mode the whole way through, but 2 days sipped about 10 percent of my battery when I tried, so I fully believe it was possible on that device. It downclocked the processor, turned basically everything off, like you said, and even lowered the display resolution and color to greyscale. I don't think I've seen a later phone than that with such a huge Ultra Power Saver.

My iphone does that without changing a setting. You just charge it and if you barely touch it it will last several days.

DepartmentOk1054 t1_j6x7hwm wrote

Not sure why the downvotes, but you are correct. I had the iPhone 13 Pro Max, that thing lasted days before I had to recharge. On my S22U Ultra. I have to recharge it everyday.

Oddity_Odyssey t1_j6x9p5n wrote

My regular 12 will still get me two days and it's on 90% battery health. And like I hate iphones. I only got this one when Google fucked up the pixels. But I mean you can't deny the power of iOS

It's mostly because of notifications. I honestly think Google's code for handling notifications is not efficient.

Just turn off all the notifications and turn on battery saver mode to medium (CPU runs at 70%).

My phone still lasts 3 days of on/off usage. It's a year old.

Also manual sync for calendar and email. I don't have a Samsung but my old LG used to have a sync when charging option that I wish I had that on my Motorola.

Otherwise it would sync if I opened the app.

Not even ultra power saving, but just the regular power saving mode is great too. I keep my S22 Ultra on that literally all the time, and it often lasts more than a full day of regular use, longer than my old phone. The baseline performance is so great that you never notice that it's been throttled.

ticcedtac t1_j6y496w wrote

Do they still? I think that was replaced by Emergency Mode and my S22 Plus lost it when I updated to oneui 5 and there doesn't seem to be anything equivalent anymore :(

Right but only helps you if you were at 100% and turned it on before you started out on whatever you are doing that would warrant an emergency satellite phone. In reality, you drove out to where ever, used the phone for directions, and now the phone is down to about 60% by the time you start. Being out in the hot/cold kills your battery while it constantly tries to find service. And before you know it your battery is at 10%. A garmin inreach in its most battery-heavy mode and conditions will last for 2 full days. If you are going for full battery saver mode it can be ready to use for a full year.

My phone is currently at 70 percent and battery is in good health. Estimated time was 2 and half days......ND have the s10. The batteries have gotten bigger on newer gens

FrostyMittenJob t1_j704kyx wrote

So you just got back from a 8 hour hike without cell coverage and used your phone to navigate to and from home and are still at 70%?

welchplug t1_j70543i wrote

Well usually when I am on hike I don't touch my phone. Why the hell would be on my phone? In addition my phone is always on normal power saver mode. After a work (about 12 hours) my phone is usually around 60 percent and that's with listening to music all day.

FrostyMittenJob t1_j707q23 wrote

Right and that's great in a climate controlled environment with wifi or strong cell signal. It's an entirely different beast when you are out, it's over 85, and your phone is constantly trying to find a signal. It ultimately doesn't matter if you are using your phone or not. If it's on the battery is being nuked. This isn't just some random opinion, this is how battery powered electronics simply work in the extreme heat and cold

I go snowboarding on mountain tops all the time. I keep my phone in my pocket. Its not sitting in the snow lol. Yiu are just trying to justify your purchase lol.

FrostyMittenJob t1_j70l6ze wrote

I don't own an inreach. Obviously your phone isn't sitting in the snow but the air, crazy as it may seem, is cold too.

Here are a few articles to help you out

I realize is this r/gadgets, but there is actually the option of just turning off your fucking phone when you don't need it

If you are buying your cellphone because it has a feature that you are going to rely on in a life or death situation you don't want the usability of that contingent on whether or not you remember to turn off your phone

Btw I don't work in climate controlled environment. I own a bakery. It's regularly 90+

FrostyMittenJob t1_j72e6jm wrote

Of course they still work, but being exposed to high heat leads to faster degradation and quickly drain your battery. This isn't my opinion this is a well documented phenomenon.

welchplug t1_j72hnj8 wrote

Yeah marginally and not enough to be really noticeable. Again 12 hr days of being in the bakery with 60 to 70 percent charge at the end. The battery doesnt instant drain just because its a little hot. Anyways good day!
