I really hope Samsung fixes this "issues".

It sucks. Hard.

What is the problems with the exynos processor this year?
You think software issue or harware issue?

 

[htcplussony]

Whats wrong with Exynos cpu. Well it is the tortoise and the hare.

Intel speed shift it is not.

Exynos 9810 seems to be another 5410: made to impress in synthetic benchmarks, and stop at nothing to achieve that.

I will take this review with a grain of salt....agreed most reviewers don't go so deep and basically review their devices after a week of daily usage....but still if the problems were so deep..it would have been reported.

Like i said in the comments there, i believe most of the deductions from that test will not impact your day to day life. Information is great, but one must know when you need a "summary" and when a "thesis"

I am still buying this beauty next month and i am sure i would be satisfied.

Ive heard reviewers say and show on video the exynos having better battery life and a faster processor. Who to believe? I returned my snapdragon for an exynos because my SD got such horrible battery life. Just got the exynos so we will see. At least it can have root.

Grain of salt? Did you even read the review?!

Sure, Exynos this year will still feel smooth, just like it did last year; but there is no denying to the fact that Samsung is still not up in its game when it comes to GPU efficiency. Samsung will still need to tune the scheduler on this Exynos (if not already tuned with March update). And unlike those most phone reviews out there, Anandtech folks actually go back and update their reviews after substantial changes that manufacture might have made (AT also reports those suggestions to OEMs when they review).

Anandtech is one of the few tech sites remaining that review hardware like how hardware should be reviewed.
Do not dismiss such hard work just for the sake of sounding edgy on the internet.

I had the s9 for 10 days, sold it because I got much worse battery life than on my nearly one year old s8 and there were nearly no improvements at all. I only noticed these 3:

1. fp reader, better placement and much more accurate.
2. Sound from speakers which i never use, much better.
3. dual-sim.

In the end i felt that selling the s8 for 400 dollars more than I would get for my s8 was definitely worth it. Very happy with that decision.

As i said , such reviews have no real benefit for me as a everyday consumer. There's nothing to say that the author hasn't done an excellent job...he has. Point is whether you need such deep analysis , when you are never going to be affected. My view is <1% will notice these things.

Secondly battery is a very subjective thing, it depends on user to user and companies generally take a month or two to fix their stuff after a new release.

 

[jrharvey]

So I've had the exynos s9 all day and I gotta say it's much better battery life than my snapdragon s9. Only problem is now LTE doesn't work. Ughhh.

Even with a Exynos cpu, it will has godly performance.

Yes it's in depth but not always how it really is.
Look at his benchmark charts and realize that SD835 is almost every benchmark faster than Exynos 8895 and 9810. Well, we all know it's not the case in real life.
Apple's A11 is fastest soc in every benchmark but in real world iPhone 8 is nowhere faster than Android flagships depending on sort of apps you use.

Never trust benchmarks only. User experience is more important.

Those are not benchmarks; those are to test specific aspects of a SOC.

SD835 does still beat Exynos 8895 and 9810 when it comes to GPU intensive tasks; that is to credit QComm's exceptionally mature Adreno architecture.
SD835 will continue to beat these 2 CPU's when it comes to performance per Watt due to that.

SD810 was a failure, SD820 managed to narrow the GAP with E8890, and SD835 more or less went head to head with E8895.

Sure, synthetic benchmarks still favoured Exynos year after year, but the reality has not been that clear due to Samsung's DVFS being a year late compared to QComm. Those things might not be relevant to how a device performs (due to difference in choice of system variables and tuning); but they are very much relevant to judging how those SOC were designed and implemented. That is what the point of those tests are (over AnandTech and for their usual style of reviewing stuff).

You can check speedtests on ytube for SD845 vs E9810 and decide for yourself (speed tests are usually dumb across different devices but you can make some relevance when it comes to same device with different chips).

One such example:

AnandTech has published a testing article here for those of you who have been following this discussion and/or interested in improvements that Samsung and/or developers can bring to Exynos S9/S9+ via kernel modifications.

Improving The Exynos 9810 Galaxy S9: Part 1

Interesting read.

TL/DR:

Today’s results are just meant as a quick preview of the Exynos S9’s behaviour when removing what I believed the most offending parts of Samsung’s mechanisms. The results are very promising as we are essentially getting real-world performance boosts while at the same time seeing efficiency improvements and battery life improvements.

There is still a lot to be done - I haven’t really touched the scheduler or DVFS scaling logic, but I’m confident that it’s possible to improve things further. It’s unlikely that we’ll end up matching the Snapdragon 845 variant in battery life, as there are efficiency curve considerations at lower performance points that simply cannot be changed through software. But closing the gap as much as possible seems to be an attainable short-term goal.

Now Samsung chimed in on the issue

I'm extremely intrigued but also confused at the same level. I ordered a regular S9 Dual-SIM after reading reviews and reports that told me it was a great device and a nice upgrade from my S7 Edge. Then I cancelled my order because I read that a lot of people with the Exynos variant have battery related issues. Then I kept reading and noticed most of these reports where from devices just a couple hours or days old. The more recent reviews seem to show a different picture. While still a mixed bag, battery performance seems to be much less of an issue in more recent reports. For some it's even better than their previous devices. The reviews/reports who seem to praise the performance (battery) the most include almost exclusively people who compare it to the S6 (Edge), S7 (Edge). So, I placed my order again for a Coral Blue S9 Dual-SIM. Don't care for the Dual-SIM but somehow it's the only variant available in Germany. Whatever.

This is by no means an accurate analysis of the current or past situation. It's my experience. It's not representative in any form or function.

The upgrade will be very notable over s7 generation.

S7Edge gave me great battery (6-7hr SOT); S8 and S8+ gave me lower than that (4-5hr SOT). Now S9+ again gives me great battery (6-7hr SOT).

All of them have been Dual SIM models; and yes, I did change phone that often since I had a way to upgrading for a very small price difference.

S9+ upgrade wasn't as cheap for me, so I'll have to continue on this for a bit longer. It is an exynos S9+ from India; and performance has not been an issue so far for me.

I had the regular s7 before and upgraded to the exynos variant s9, and it is true that battery life during the first week or two is not adequate. Battery life has improved much and overall it's still a great device compared to other devices out there. Yes, I do wish the battery capacity is larger and Samsung do further optimizations to get battery life on par with the snapdragon variant it isn't the worse and I'm able to get a full day out of it. Honestly if you can wait, wait for the s10. The new 7nm chips and rumored higher battery capacity should make a killer device. But you can't go wrong with the s9 believe me. Other devices out there are flawed one way or another and the touchwiz experience is honestly approaching perfection, yes it was terrible years back but now it's way better than stock android in my opinion.

In the screenshot below, the power saving mode only has decreased 10% screen brightness only. No other altered settings.

This is what I'm talking about.
Battery tests, even in-depth semi-scientific analyses are all over the place and inconclusive. It is true that battery life is very user dependant but there should be a common theme all across the board. However, I don't see anything like that. I can't dealt with this for 2 years. I cancelled my order and will wait for a better deal on the S9+.

 

[Sachinfan]

So , it seems , my reaction to the anandtech review was spot-on. S9 , irrespective of the cpu variants, is still a great device and we must not confuse ourselves with too much information where none is reqd.

God willing, I should be getting my hands on the s9 in early May.
