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

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?

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.

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.

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.
