Strange Reset

Strange thing happened to me today with my S9+.

Due to some reason, I was not getting enough internet speed (Mobile Data) and I was in a hurry to book a cab. So, I thought rebooting might fix the issue.

After its rebooted, it showed me a blank screen with a single option "Reset" and a message, "something went wrong, please reset your phone". Nav Bar is also available but none of the buttons are working. Only active option is RESET.

At this point, If I click on Reset, then it will delete all my data. So, I forcefully rebooted it again. This time it went straight to factory resetting and erased all my data. I did not take any backup for today's stuff which includes some videos, pics, messages and some documents. Everything was erased and booted as a new mobile where you setup the mobile.

This is very strange and never happened to me like this in my life. I did not even hold any other buttons while rebooting and did not even root the phone. I'm not sure what went wrong and how it ended up erasing all my data.

Well anandtech has spoken in detail of bad battery life on exynos, that's a kind of bummer.
[Samsung Galaxy S9+ Guides, News, & Discussion] Killer333:
They have only S9 Exynos variant and battery life test is for the same.

But we can already see that battery life is not that great depending on the reviews from our forum members.

On wifi, you'll get decent/good battery life.

But on mobile data, it sucks. Battery drain is more on mobile data.
[Samsung Galaxy S9+ Guides, News, & Discussion] kumar abhishek:
He also said its not specific to s9 but the exynos 9810 battery draw is very high and there is a lot of power leakage.

The results of anadtech are in sync wuth gsmarena which quite in the beginning reported severe standby drain on exynos s9. :(

Hi - I'm about to switch from an LG v30+ to the s9+. Any specific stuff I should be aware of?
[Samsung Galaxy S9+ Guides, News, & Discussion] piku2008:
have anyone purchase s9+ from airtel i.e. pay upfront 9900 + (2799 * 24 months) ?
[Samsung Galaxy S9+ Guides, News, & Discussion] rn9215:
I did on Wednesday and the phone is yet to arrive, not a bad deal IMO, i am already paying around 1.2k a month for my phone bill on Airtel postpaid.

Now thinking about what to do with my S8+ :D
[Samsung Galaxy S9+ Guides, News, & Discussion] Dr.Gonzo105:
Hey!

Once you receive your first bill can you tell my who the bill is.

Like is it mentioned on the first page of the bill about the EMI or is it like other normal bills?

I get reimbursed from the office for the phone bill

But if I they mention anything about the EMI on the first page I won't get reimbursed

So till now one has been able to clear off this doubt ?

New update: Improved Call Stability & Wallpaper Quality

Hit the update on your phone manually :fingers-crossed:
[Samsung Galaxy S9+ Guides, News, & Discussion] v_square:
Sorry to say but you are trying to be delusional here. If something has a problem, we need to accept it instead of defending it. I've been a Samsung user since S2. That's a long time man. But still I never defend them when they screw up. And believe me, they have messed up the frequency-voltage ratios in the wild hopes of chasing A11. And I know what I'm talking about since it's my job buddy.

Nothing is more funny than designing next generation LPDDR (LP here stands for Low Power) RAM for Samsung, and looking at your brand new S9+ sipping away battery stealthily.

If battery life is what you're after, don't bother switching.
[Samsung Galaxy S9+ Guides, News, & Discussion] v_square:
Exactly my thoughts. Why do I need to spend freaking amounts of time running through stupid menus? Out of the box experience is what matrers the most. That's not something Samsung has learned over the years sadly.

Even software experience is sub par on this device. Attaching a short clip.

after that its safer to put it on charge :cowboy::cool:
[Samsung Galaxy S9+ Guides, News, & Discussion] One Twelve:
How much SOT did yu get under similar usage with your previous phone (S7e was it ?) which i presume is on data only according to your screen shot

What is the difference ?
[Samsung Galaxy S9+ Guides, News, & Discussion] v_square:
A 2 year old S7 edge breezed through 4 hours of SoT at least. When it was new, 6 hours was average. To bring things into perspective, S9 can't even deliver what its 2 year old predecessor could.
[Samsung Galaxy S9+ Guides, News, & Discussion] One Twelve:
I'd expect 5h on data to be normal. There isn't all that much difference between generations.You didn't even make it to 3h.

But SOT Data can be variable. On a sunday with airtel i can get an hours more SOT than on a weekday because of less congestion. Sitting in the same spot doing the same thing.

What about wifi only ? less variables and more consistent.

What is the difference in SOT with wifi only between the S7e & S9+ ?
[Samsung Galaxy S9+ Guides, News, & Discussion] Mr.Raviteja:
Anyone using Tempered Glass? If yes which one? Please provide a link.

I bought mine from Pai International store on 28th March
[Samsung Galaxy S9+ Guides, News, & Discussion] v_square:
I would partially agree with this comment. Agreed, there isn't much of a difference. But whatever that little difference is, it shouldn't be negative. Right?

See, let me get things straight here. There are 2 routes to getting the max possible performance. Either you improve your micro-architecture, throw in a lot of parallel paths, and, use pipelining as and when possible. Or, use a higher clock frequency. First move requires a bigger die size (chip size), this is the route apple uses. Second route, umm, isn't really ready for prime time on mobile devices. Problem is, higher clock frequency demands a linear increase in power.

Have you ever wondered why Intel processors haven't really scaled up their clock frequency over the last few years? Reason is simple, power consumption. Idea is to not to let the consumption take its precedence over performance. Samsung, when it couldn't deliver the same performance as A11 on their micro-architecture, went the second route. Do you think Qualcomm 845 couldn't run at the same frequency as Samsung's 9810? It can, because the manufacturing node decides the frequency, not your front end design. But Qualcomm can't afford to do that because of one simple reason, power consumption.

And it's not like I'm all out blaming Samsung for going this route. But the fact is, if you choose to use higher clock rates, optimize your design so as to leave minimal power footprint.

My last 2 cents. Won't be writing such essays any further. If you are happy with your device and it's battery performance, stay that way. I'm clearly not, and I will never recommend this phone to a person who's priority is battery endurance. Peace mate. :angel:
[Samsung Galaxy S9+ Guides, News, & Discussion] One Twelve:
Sure so let me qualify. An improvement in SOT to be had going from 820 to 835. 14nm -> 10nm. Thing is i had a tough time getting someone i know with an S8+ to admit this. His SOT's were no different to the s7e he had. But how much can be expected going from 835 to 845 ? this is where gains if any will be less.

Then lower that frequency. If battery is what you want then that is what you do. And you can :)

So qualcom loses to exnos in performance benchmarks that nobody really cares for yet delivers on battery that everybody does care for. Funny how roles reversed there.

I can handle essays that go on for weeks with several people.

But i asked for your wifi SOT :)

On the s9+ and how it compares with the s7e ?
[Samsung Galaxy S9+ Guides, News, & Discussion] v_square:
I would've happily done it provided the Samsung experience didn't stutter this much. It fails to provide constant 60 fps even when it's going all blaze on 2.7 Ghz. How do you expect it to cope up when it's running at even lower frequencies. Do check out a GIF I posted couple of pages back in case you're wondering what I'm talking about.

That's exactly what I'm saying. I'm all in for performance boost, BUT, not at the cost of more power draw.

Don't have the exact figures for the S9+ as of now. I've not been able to spend a whole day on wifi with this phone. Will surely update when possible. S7 edge hovered around 7 hours, when using wifi the whole time.

Nop. Never used one. Never gonna use one .
[Samsung Galaxy S9+ Guides, News, & Discussion] One Twelve:
I did but its hard to see the lag there, You experience it so its more clear

Camera is a mixed bag as well. This phone looked so promising a couple of weeks back. Oh when will they release a snapdragon version in india ?

Right 7h sot is what i was expecting too. Anyway mention me when you have some figures for wifi. i don't put much stock in tests that do not employ humans in the test. That is to say i consider automated testing in this context to be superficial. Nice numbers and nothing more

;)

This tells me offscreen drain is fine. Its using the thing which hovers at higher clocks more than necessary is not. In need of optimisation

https://www.anandtech.com/show/12520/the-galaxy-s9-review/8

Andrei agrees with you btw when it comes to unbearable lag with slower clock speeds. As it is there is this must use it at FHD and nt FHD+ now if somene says run it at a slower clock people will say for what did i pay for this ....

Whether an update can fix this ? yeah, they'll run it at a slower speed like the 845 and everyone will live happily ever after :D
[Samsung Galaxy S9+ Guides, News, & Discussion] v_square:
I couldn't upload the video here. The lag is clearly visible in that video.

And Snapdragon version here? I don't think so. That happened way back at the time of S5. And that too because snapdragon version was 4G compatible.

Right now their focus is on Note 9. S9 is a thing of past for them. I'm not keeping any fingers crossed about any improvements in battery life. I'm gonna switch whenever I get a chance to. I want to love this device, but it seems to not love me back :laugh: Gets exhausted so quickly.

Will try to analyze the behaviour on wifi. I guess the mobile radio modem is really badly optimized.

[Samsung Galaxy S9+ Guides, News, & Discussion] lycan_codex:
I was lucky enough to have a colleague who wanted the S9+. When pixel 3 releases he will.take back his phone and I will take mine to exchange and buy the next pixel phone.
[Samsung Galaxy S9+ Guides, News, & Discussion] One Twelve:
Lag is one of those contentious topics where a microsecond here and there that is unbearable for one isn't a big deal for another. If you used a pixel or oneplus previously then its even more apparent. But that's not what you said you said you find there is a delay compared to the s7e

heh, you remember that sh*t show. S5 loses 25% of its sale price within a month. Smashing news for early adopters. If you were waiting you think ah, give it a few more months. Say you wait for 3 months then decide to jump in. No, in the 4th month sammy decides they will offer a snapdragon version with 4G so i imagine a few people got their fingers burnt with that S5

They will fix the battery life. Then people will complain that it lags like they always say with previous exynos. This is why lag is contentious. Then there will be custom stock based roms that 'fix' the lag and we're back to mediocre battery life once again. but see its faster than everything else out there. It gets warmer too now that's why the battery doesn't last that long. But you know there is fast charging bla bla..

As i said earlier i'm wiling to live with some lag if it translates into good battery life. And exynos for the last three generations have outlasted snapdragons

I just don't get it. Who makes the 845 ? Sammy Who makes the exynos ? sammy

yet there is still this differernce...

ya, i know you explained why. But if you get it why hasn't sammy..
[Samsung Galaxy S9+ Guides, News, & Discussion] v_square:
Qualcomm, Apple and even Samsung design the hardware. Only the design, or you can say the microarchitecture. You're least bothered about hardware implementation at this stage, called front end VLSI design.

Then comes the back end VLSI design. Manufacturers like Samsung, TSMC etc who actually translate that design into real hardware and build real chips.

Both stages are critical. A package is only successful when both the teams know exactly what they are after.

I've to give credit to Samsung, Intel and TSMC for drastically reducing the individual transistor size (almost 6nm now).

Now coming back to S9, their's nothing wrong with the manufacturing process here in this case. The microarchitecture is not optimized and strives to achieve the max possible performance, which isn't good for a mobile device. This won't be an issue if the same chip was used in a device with AC power supply.

Also, as you said the battery life can be improved by slightly bringing the frequency range down, but then it'll lag. Well, it's true to some extent. Look at the competitors for example. No chip currently runs at 2.7 GHz in a smartphone except this one. Still, somehow Samsung Experience isn't the smoothest. See, problem is, if you've lazy fat ass engineers just passing their time, you'll end up with such half baked products. A 'mobile' device is meant to be 'mobile'. How do you expect us to call it a mobile when it doesn't fulfill that basic criteria?

On a side note, I'm working on GDDR6 DDRAM. If you feel you feel your PS6 isn't snappy, come and criticize me :D
[Samsung Galaxy S9+ Guides, News, & Discussion] One Twelve:
What screen resolution are you on btw ? FHD or WQHD

Screen brightness in %

Whether you are running in performance mode or other

When i look at the Exyns battery thread i find some getting results you expect and others unable to get anywhere close.

Take

this

for example. His 4g is either band 12 or 20 or other similar 3 digit 4g frequency so its close to a wifi sot. His only two tweaks are 10% brightness (adequate for indoors use) and dark theme. I'm surprised he gets as much with qhd tbh, thats what i'd expect with 1080p
[Samsung Galaxy S9+ Guides, News, & Discussion] v_square:
Do you still believe full hd or qhd make any difference? It does, but only when you extensively use your phone. Extensively in the sense you're quickly shuffling between lot of items on screen. See, the only margin here is the juice saved by putting less stress over gpu. That's anyhow is very minimal. Display still takes the same amount of power, after all no pixel is being turned off.

I'm using everything on auto. Optimized performance mode. No dark theme.
[Samsung Galaxy S9+ Guides, News, & Discussion] One Twelve:
The difference in savings is as much as an hour with heavy use. Heavy use defined as down to 5% in little over 12h or under. Under those conditions i expect an SOT around the 7h mark with wifi only or a 3digit frequency 4g band

I've seen tests demonstrating this. I was surprised there was a difference between resolutions but there is a good reason sammy's ootb default to FHD and not WQHD. And there isn't any good reason to have QHD on a phone size screen. Even on a 15" laptop i use FHD instead of 2 or 4K and its perfectly fine.

I can't tell how much you gain with FHD, you will have to test. But that other quy isn't facing any hit with qhd, maybe he is.

What is brightness in %, auto isn't clear. Adaptive brightnes is a pain, its supposed to learn but it doesn't. Earlier auto birghtness was better. With M or is it N this adaptive nonsense can screw with battery. Try manual brightness maybe

---------- Post added at 11:21 PM ---------- Previous post was at 11:05 PM ----------

Check

this

out,

40/60 4g/wifi

Down to 5% in 14h, SOT 7h+

Normal
[Samsung Galaxy S9+ Guides, News, & Discussion] v_square:
There's no point of comparing my results with others. All I care about is my usage. And as per my usage, it's not enough. My usage pattern hasn't changed and it's still the same as before. 2 hours of music and a bit of social media while commuting to work. I barely use the phone at work. It just stays there on the desk. AOD enabled though. Listen to music again when heading back home. A bit of YouTube, browsing, and chats before sleeping. It's dead by 11PM with around 3 hours of SoT.
[Samsung Galaxy S9+ Guides, News, & Discussion] One Twelve:
In other words should be doing better with this pattern of use.

Two things to try

Boot into recovery and wipe the cache. See whether your lag remains or goes away. Whether battery improves.

If not then start again from scratch with a factory reset. Firmware updates are nothing but a dirty flash and can sometimes go wrong.

Do those two things and then show me the same SOT's you've got and maybe there is something to what you said earlier.

Having read that entire thread there are mixed results, some with normal results and some with abnormal results like yours.

Try and lets see.

What is your standby drain btw, if you leave the phone overnight without touching it for say 6-8h, how many % does it lose ?
[Samsung Galaxy S9+ Guides, News, & Discussion] v_square:
Can't afford to do it now. May be on weekend.

Night time drain is around 4 5 percent. But data is off at that time.

Factory reset is what I'm thinking about. But I know that's not gonna help. BBS shows no abnormal wakelocks. It's just that the battery keeps on leaching out.
[Samsung Galaxy S9+ Guides, News, & Discussion] One Twelve:
4-5% overnight is little over 0.5%/h that's not bad for stock. BBS won't show much. It means your off screen drain is normal

But your on screen drain is not. There are no tools i'm aware off to diagnose here. And this is difficult to figure out other than surmise that its using more power than necessary by running at higher clock and staying warm longer than necessary. Might not be sleeping properly during the day

Wiping cache helps to sort out off screen drain, buggy behaviour it might not help with on screen drain. For that only a full reset might help.

You're already running in optmised mode so there isn't any extra load here.
[Samsung Galaxy S9+ Guides, News, & Discussion] v_square:
Problem is when data is on. It just sucks away all the juice. And this is when I'm not even using Facebook or anything of such sort, turned off Bixby, turned off google feed. The only app I use is WhatsApp. God knows what would happen when I start using them.

[Samsung Galaxy S9+ Guides, News, & Discussion] One Twelve:
Maybe do a standby test with data enabled then. Remember to let it sit at least 6h without touching it. Screen on must be less than a minute within that period

Actually do two standby tests. One for 6h without data enabled and another with data enabled for comparison

Poor battery life

Hello guys. I have been getting poor battery life for the past 8 days. First 5 days were good when i got 4 grs sot with 18 hrs stand by. Now its got worse. Overnight standby drain is 1.3% per hour. Drained 11% in 8 hrs. Is this nromal for s9 plus give that the battery life isnt too good. Any tips to improve? I have tried all the setting settings including wifi scanning and others to avoid background usage.

Attachin screenshots . I did use maps for 2.5 hrs but so mcuh battery drain wasnt expected. When i used my wife's Note 8 it drained just 20% after using maprs for 2 hrs
[Samsung Galaxy S9+ Guides, News, & Discussion] Dr.Gonzo105:

Battery life is horrible

It's not even lasting one whole day
[Samsung Galaxy S9+ Guides, News, & Discussion] v_square:
On the contrary, mine has improved a bit. Won't say it's good, but at least it's better than before. Attaching 2 bbs logs here. One is with data off, another with data on. I must say idle drain isn't an issue for me. It's when I use the phone the battery takes a serious blow.

Also, I've been using the phone on FHD resolution, power savind mode on with CPU throttled to 70%. No black themes and no social media apps.

Attaching my screenshots after I 'tamed' the device. Low performance mode and FHD resolution. Wifi and 4G mix usage. Although these stats look decent, if I use the device to it's full potential, SoT won't cross 4 hour mark.
[Samsung Galaxy S9+ Guides, News, & Discussion] One Twelve:
When does power saving mode kick in ? when battery is lower than a certain % or all the time. Is this same as battery optimised as mentioned in the anandtech article ?

If you were giving directions to some one to use power saving mode, what are the steps ?

I don't see a problem with off screen drain with data on 0.9% from your BBS logs. Curious that BBS reports highest CPU clock at only 1.79GHz though thought it goes higher on the s9

Still, you said you don't use the phone much at work yet it still drains excessively, at work ?

I hear AOD drains at 2%/h which is double what it should be. That's 20% battery gone in 10h, your 3500mah is like a 2800mah. Surprising, AOD's usually 1%/h on LCD screens, you'd think amoled would be better still because no backlight. i suspect it might have something to do with brightness. Maybe it drains less if auto brightness is disabled. Then the ambient light sensor won't create overhead.

Are you using face recognition

Do you use push notifications much

Try turning off google location history reporting and see if that helps for drain.
