Samsung eyes new battery tech to break free from its 45W charging prison
-
I read somewhere about a phone that had 2 batteries, that way you could swap batteries with the phone remained turned on during the process!
That was the case on the old Motorola StarTac. One battery was attached to the top of the flip, and then there was a larger battery that could be clipped onto the back. Both would power the phone so as long as one had power you could swap the other.

I mean after their latest hideous UI 7 update I'm never getting a Samsung again. I'm tired of them chasing Apple trash.

If they can charge a car in 5 minutes using 1.3 MW charging, why wouldn't 120 Watt be fine for charging your phone in 20? Also the charging is protecting the battery by reducing speed as it approaches 100%. The lifespan seems fine, I'm not detecting any deterioration. By today's standards it's not even that fast. And it is very convenient to be able to top it off quickly. That way I also don't have to leave it charging overnight, I can do it while I make coffee and eat my breakfast. That way I minimize trickle charging which can also harm the battery.
The battery has to be made for fast charging, and Samsung is apparently way behind on that.
that’s already faster than what I’m comfortable with.
Then why did you buy a Samsung?

This is why all battery protection reduces charging wattage as the battery gets more and more full. Fast charging damages batteries, faster charging means faster degradation. There's no way around that, it's just physics, entropy comes for us all. Battery makers are just betting you'll buy a new device before it becomes noticeable.

Charging when the battery full or very close to it is absolutely harmful, and that's what trickle charging does. It especially harmful if the charger isn't 100% accurate, and especially for Lithium batteries.
Apparently some people also use the term for just slow charging in general, but this is obviously what I meant in this context.
Trickle charging compensates for self discharge and the idle power used, so even when accurate, to keep charging a little bit to maintain a 99%-100% charge is definitely harmful.
It's way better to only charge to 80% for instance. Which is the reason all fast charging times for cars a measured up to 80%.Trickle charging is damaging if for instance you charge your phone when you go to bed and don't disconnect the charger until morning, that means many hours of trickle charging at near full capacity.
Because my phone charges fast, it never trickle charges for long at near 100%.

Phones have had pretty good battery management for many years now. My phone adaptive charge gets to 80% and stays there without charging until 20 minutes before my alarm when it activates charging again to get to 100% exactly as the alarm goes off. The default behavior is a basic care that makes it so the battery stops charging at 100%, waits to drop to 95% then goes back again to full in a cycle. The risk of overcharging from leaving a phone charger connected overnight has been null for about a decade. Fast charging, on the other hand will always degrade the battery. It is way too much tension over way too short of a time span.
Trickle charging has only ever meant keeping electrical voltage on a full battery for acid batteries (actually overcharging). It has never meant that for consumer electronics.

Except charging speed of a phone depends on the capability of the battery used for that phone, and new batteries that are made for it, can handle way faster charging than older batteries.

Oh my god, that is the absolute worst. So the day you are extra busy and have to get up a little earlier than usual, and depend more on your phone than normal, it's only charged to 80%! That's exactly the kind of unintelligent solutions I hate. They always fuck up when it's most inconvenient.
the battery stops charging at 100%, waits to drop to 95% then goes back again to full in a cycle.
So repeated charging from 95% to 100% which is clearly not good for the battery.

I can't wait until one if these devices blows with 5000mAh of energy

You are wrong in all of your replies, but I have ran out of time to educate you. Good day.

I dont keep up with apple products anymore, what did samsung do to mimic them in one UI 7? I thought they just added a couple of nothing features from stock android.

With a replaceable battery, you just carry a second one and swap them on the go
Isnt the problem with a swappable battery, like you describe, that the phone will lose its waterproofing?
Dont get me wrong, i dont think they should be welded to the internals like they are these days, they should be easily removable, but getting into the phone shouldsnt be super simple unless they find a decent way to waterproof a removable back plate.

In which you'd need a power bank and cable that youre carrying if you don't want to be tethered to an outlet (which may or may not be available.)
Seems a second battery is just a better option.
You shouldn’t need to do that anymore, batteries are much larger and chipsets are more efficient than when removable batteries were the norm.

Personally, couldn't care less. I always disable fast charging and have been charging my phone at 5W for forever now without issue.

A pet peeve of mine is when I drop my phone 2 feet from the floor and the battery pops out.
I'd rather see a different mechanism where you trigger a battery removal by inserting a sim tool pin, just like how the sim cards are removed. This way, we can preserve IP ratings.
Pretty sure it’s by design. It transfer the kinetic energy when it falls and keep the phone safe.
There’s reason why old Nokia is called indestructible.

I'm going to reply with a link to review of a phone that solved it with IP67 rating

That's pretty cool! i never had the S5. Looks like a good solution. It looks like it would work on a lot of phones today.
Although, i think there are design changes to consider on newer phones with more powerful hardware. I believe they contain empty space that is there to aid with cooling the phone so the solid body of the S5 shown in the link might not work, meaning there would need to be a specific cut out space for the gasket to seal against.
I appreciate that its probably not the most challenging problem to overcome, and i would very much appreciate companies spending more money on solving the issue. But i don't think its a "one size fits all" solution in a world of vastly differing design choices, folding phones and modular phones.
Having said all that, i would much prefer for there to be less makes and models of phone and for the focus to be on designing something that won't be useless in 5 years. It should all be about longevity and reducing e waste.

They split the notification shade and control panel into two separate screens, accessed via a swipe down from either the top left or top right portions of the phone. It's quite similar to how iOS has worked for a long time now. I can see the benefits if you're someone who receives a lot of notification spam, because now you can see more of that on a single screen, but I've always been very strict with app notifications so it's essentially watered down the usefulness of both. It's far from the end of the world, though, and I'm sure I'll get used to it.

Oh! I quite like that change. I guess it's similar to apple in that it's separatated notofocations from quick settings, but doesn't apple have a swipe up and swipe down? Or is it double pressing the home button? I haven't held an iPhone in many years now, so i can't remember. But how you access the two menus is different. I dont think an apple user who tried android for the first time would intuitively know how to access the two menus. So i wouldn't say samsung had copied apple. Rather, they have been influenced by the idea. Plus, i believe stock android has this as an option in versions 15 and 16
That aside. You can go into your settings and swap back to the old notification shade.
