Samsung’s policy had always been early birds get free gifts while people that can wait get true discounts minus those free gifts.

I bet they will just throw in a charger for early birds.

Unlikely, both are using same ARM reference cores, and both manufactured under the same Samsung 5nm.

The main differences are the GPU and those Qualcomm exclusive features.

Xiaomi’s flagships (early batches) usually use Samsung’s displays. Later batches they might swap in China’s AMOLED.

Sony, but again it’s not much less guilty than Samsung.

Sony been living in their own bubble and pace, they don’t really care what’s happening out there in the market, LOL.

They made their phone to their own likings and priced to their own logics, they don’t really care whether the market will accept or not.

Higher clock =/= faster

You need sufficient cooling to prevent it to throttle.

Vapor chamber, graphite sheets and aluminium frames are the cores to disperse the internal heat.

But again there’s only so much passive cooling can do. When your CPU is consuming more than 5-10W of power, it may not be sufficient.

LOL, what else did they not downgrading?

And Samsung kind of gone in reverse if they omitted the 45W charging which they introduced back in Note10 era.

Though to be fair, blindly pushing for faster charging speed but not finding ways to mitigate the heats generated when doing so will likely backfire as the battery degrading excessively prematurely.

You can just look at GSMarena’s phone review, they started stating the (actual) charging speed in their reviews since last year.

I do agree Samsung’s 25W charging is competitive for what 25W charging can go. But it’s capability is kind of inconsistent, where S20Ultra can match those of Chinese manufacturers of 30+ wattage fast charging, but not so much for 20FE and Note20.

And because of that (adoption of PPS instead of normal PD), it’s picky on 3rd party charger. Most of the 3rd party charger out there don’t have PPS support.

Again, as state in my previous post. The compromise of faster charging is likely faster battery degrading too (heat factor). So except for a clear cut advantage like that of Xiaomi 120W or Oppo 65W VOOC which can further shorten the full charge time and have incredibly short half charge time, the general market standard of >50% in 30minutes and fully charge slightly over 1 hour will be the sweet spot and acceptable “compromise” for most people.

Form the other thread, another former tried this and say he can achieve the 45W SuperFastCharge.

I have the same charger too but didn’t try if it can fast charge my father’s Note10+

For some reasons, N20U is the slowest charging model among all its other galaxy peers launched last year, despite having smaller battery capacity (vs S20U)

So far only S20U can cross the 1hr full charge with 25W charger.

Others fall slightly off (more than 1hr) and Note20U most noticeably so.

The market standard (since Apple introduced 18W PD fast charge) is 50% in half hour. Anything follow close to it (with exception of M51, it’s because the battery is too big by itself, LOL) shouldn’t be much of a problem.

This, except for the assumably bigger heat generated factor, I hadn’t came across a solid claim that fast charging will do significantly more damage than slower charging.

Having to charge by day time indicate that guy may be a heavy user, where the battery will degrade noticeably faster compared to people whom don’t use their phone as heavy loaded.

SD888 is now known as SD810V2, the overheating fireball.

It’s due to the increased clock rate from SD865, but the manufacturing process of Samsung 5nm doesnt seem efficient enough to offset the extra powers, thus the chip consuming more power (and produce heat).

It’s even hotter than Mi11, LOL...
2:07


The video another guy posted above explained in details why the problem with SD888.

In short it’s because SD888 is like an overclocked SD865 (they overclocked the GPU on SD865 and get pretty much identical performance with SD888, LOL) and the worse this time round is Samsung 5nm doesn’t seem to give the die shrink improvement than TSMC 7nm did. I reckon the integrated 5G modem isn’t helping on the heat management either.

Samsung appeared to use graphene cooling, like what they did with some of the Note20U. Strangely for Note20U, vapor chamber or graphene cooling doesn’t seem to affect the cooling performance of Note20U much.

Not really. SD doesn’t fate to win over Exynos yet.

If you take a deeper look at SD888 and Exynos2100, you will realise they’re almost identical on CPU tech this year. In fact Exynos is clocked higher than SD888 cores to cores.

Qualcomm didn’t tweak much off ARM reference design this year round, hence it’s almost identical to Exynos. And to double down on the similarities, Snapdragon this year is manufactured by Samsung too, thus the previous discrepancies caused by TSMC vs Samsung fabrication shouldnt happen again this year.

But again, other than the CPU, other parts of chipset may start to differentiate itself, especially the GPU and modems.

What’s interesting is even SD888 seems over ambitious and over claimed on the improvements this year. Samsung’s 5nm can’t sustain properly the improvements yet. The improvements (benchmarks and etc) are not sustainable unless the excessive heat issue is resolved thermal throttling to a lesser extent. This also translate to higher draws in power and lesser battery life.

Graphene battery is like Quantum computer.

Sounds perfect on papers and mentioned every now and then but nobody seems to be able to manufacture an actual working product just yet, KEK

My 2cents
- Exynos2100 likely on par with SD888 in CPU performance this time round
- they both likely sucks the same way in thermal throttling and power efficiency
- exynos might even do it a tard better in thermal as Qualcomm’s new GPU is just an overclocked old Adreno on steroid, which isn’t going to be friendly to power consumption

Play game go Apple

Play games then Snapdragon is generally the better choice, for the wider compatibility and more powerful GPU.
