ROG Power Saving Mode

Hello,
What do you think about ROG power saving mode which became available after B320 update?
I tried it for a couple of days but found out that it drains the battery faster! In fact after a full charge the battery manager told me that the battery can last 27 hours, and when I turned it off it showed that the battery can last up to 29 hours.

lol, thats odd... do u actually notice the lower resolution?

I only notice lower resolution in one app, the rest seems the same to me. But again, I don't have the sharpest eyes

That's weird I actually think it helps. I never really pay attention to the battery manager. But after heavy use with ROG on I get home from work with 52% left after a 9 hour work day. As far as noticing resolution I'm able to tell the difference because it looks the same as the huawei mate 2 with it enabled .

It lowers the resolution of everything. You can see it on the homescreen pretty easily. Not worth the quality loss for me personally, battery life is good enough.

Battery life has definitely been better.
Resolution reduction does help to get the cpu and graphics load reduction by about 30% and.this helps in smoother performance as well as better battery life.
My friends were unable to make out the resolution change although more.apps have distorted screen arrangements.
Happy with it

Thanks for the replies. I gave the ROG another try and I found out that it really saves the battery life a little.

This mode is great for gaming as the resolution drop in game is not that noticeable. Can definitely squeeze extra 1-2 hours depending on the game.

Newly bought S8 and a 4.5h battery life. Is is normal?

So I got my GS8 yesterday and this is the battery life I get with:
AOD off
No battery saving profile
Wifi on all the time
4G network but no data
Automatic brightness
No gaming, about an hour of video playback
Since I can't share outside links I'll just write the info here: (From 100% to 3%)
Last charged: 10h ago
Screen on time: 4 hours and 30 minutes (812mAh)
Android System: CPU total: 3 hours and 11 minutes (312mAh)
This is not even close to what I expected, do you think this is normal?

Normal. It's happened with both my S8 and my G6. Your battery life will get better in 3-5 days. Android is setting stuff up and optimizing battery life behind the scenes.

You bought it yesterday. Give it time to settle.
Also, turn off automatic Samsung cloud backup, it's on by default.

I am 45% with 4 hours SOT. But I have days like yours with 4 hours SOT at end of day... It depends on how you use it.
Also depends if you debloat it or not (no root required)

What did you expect from a 3000mah battery? It all depends how you use the phone, i can empty the battery in an hour if I want.
4.5h is more than respectable, if you want more lower the brightness and use a black theme.

Another question guys. Is a 6% drain over 7 hours of being idle normal? Wifi on and AOD off.

It pretty much. Also depend on how many apps you installed. If you dont want it run much, add it to smart manager sleep list. My idle about 3hrs/1% man. This is my battery current round and apps list. About 10% wasted battery because I did clear davikcache a few times

This should be normal. with AOD on, my phone takes about 2% per hour, but when browsing webpages, every 1.5 hours costs about 10% of power, watching videos should take more. also, the 1080p and 2k resolution have notable differences. so it seems that the white-background screen cuts down most of battery life, i think.

hmm, i turned my phone as power-saving as possible - brightness is less than half of the bar, suspended all background apps, and FHD resolution. also, after some days of usage, the system should be able to auto balance the power consumption by sleeping some unused apps and some Samsung's system services maybe. so i don't think this is an issue.

Dont believe every sot someone posts here, i've seen a few 8 or 9 hour sot's but i'll bet the brightness was as dim as can be and they used a black theme. Or they were probably reading a book on the phone which uses no cpu at all or using the battery saving feature.
Your z1 also had a 3000mah battery, yet it had a smaller/dimmer screen, lower resolution, less ram, much slower cpu/gpu. How can you be complaining?

yeah, you're right, the AMOLED screen with high brightness and white color is the real battery killer. also BTW, does the 'sot' mean 'screen-on time'? sorry for my bad English...

Yup screen on time

4.5h is more than enough ! I am coming from a S6E+ it used to give me 2h SOT MAX ! Hated my life with it.

Do you plat Pokemon Go? I find a lot of people I see complaining about battery do, that game is very poorly optimized for battery consumption.

How's the screen look? And speed of the device? Hard to hold?

Exteremly perplexed. Out of the box this things battery was amazing on day 1.. 5 hours sot from 60pc to 20+. On day 4, just watching YouTube and scrolling on Instagram for 40 minutes the battery dropped 10pc! Disappointing for a 7nm chip and 5000mah. Ive been monitoring battery consumption and apps, which I haven't installed much. Projected to have 55 hours left on battery, 70 hours on saving and 230 hours on ultra. Do you guys think it's still calibrating?

Yeah, i think it's still calibrating... Remember to never charge your phone to 100% and never plug the charger when it like 1%... Always charge from 20% to 80% ... This will you will have a great battery life...

Excellent battery!

Can we get more posts with app usage? Showing SOT without what apps you use doesn't mean much

This phone is a beast.
With same configuration my Mate 9's best was 6+ hours SOT, Mate 10 pro was just about 7 hours.

Power saving mode off.
Auto brightness on except while on total darkness.
Double SIM cards from different providers active the whole time.
Walking and driving half of the day.
No WiFi at all except when I had to transfer a few GB of data to another phone via WiFi direct.
YouTube vanced active most of the time when screen was on plus a few hours while screen was off too. You can see I downloaded 1.4GB of data yesterday and that was mostly 240p video and last two hours 144p video.
I forgot to say I had Bluetooth on for more than 10 hours, and that's exactly how long time I was playing videos on YouTube vanced. Because I listen through the wireless earbuds.

Is anyone having shorter SOT post the emui9.1 update?

at least it's worse with me than with 9.0

OnePlus 7T, unlike the predecessor OnePlus 7, is
confirmed to have 90Hz refresh rate.
Hence, whoever is going to post SOT, do not forget to mention refresh rate used (90/60 Hz), screen resolution, "tweaks" and "measures" taken in settings etc. Also show full screenshots. Thanks.

GSMArena has given an endurance rating of only 84 hrs (90hz) & 89 hrs (60hz) which are not that great considering OP7 which had 102 hrs. I cant understand even at 60hz why so much difference compared to its predecessor?

Higher clock frequencies

So is there way to underclock to 855 rates and get about 100+ hour battery endurance ? It's big hearthbreak for me these battery stats, still better than my HTC U11, I get around 3.5-4 hours screen on time. Device 2 years old.

Not sure it'll compare to my OnePlus 5 record
Of 14 hours 40 something minutes in one charge
But I think 10 hours should be possible.
Here's my old thread, I always requested proof, app list, battery stats and installed ROM.

No played much, max for 40 mins, in that 6 hrs.

brightness?
Since this screen is a 1000 nit, could it be the auto brightness settings are up way to high, and thus much higher battery use. As far as i know, the clocks on the 855+ are a result of binning, so same voltage with those clocks, unless that is inaccurate?
watching this vid, with what he says is equalized brightness he manages to get 3+ hours of pubg, along with youtube etc, for 8:46 of SOT. Now as i have a 6T this is pretty appealing, but reading a lot of reviews, it seems 5.5 to 6 hours is the average and i wonder is that because of having brightness wayyy up, if the slider isnt balanced, or rather linear. 50% could be 500nit, which is max brightness on a lot of other screens. Thats 45nits brighter than max on a 6T for example. Just trying to sort out the discrepancy, between this gaming test, and what reviewers are getting. I cant imaging 4g modem is that big of a difference.
—------------Update-------------
In terms of battery life, the 7T put in 8 hours and 47 minutes of work in Tom's Guide's custom battery test, where phones endlessly cycle through websites at 150 nits of screen brightness until they run out of juice. Decent though that is, that's not only worse than the OnePlus 7 Pro (9:31); it pales significantly when compared to the iPhone 11 (11:20) and Samsung's Galaxy S10 Plus (12:35).
Click to expand...
Click to collapse
this from Tom's hardware seems to rule out over bright theory as they control nits to 150, but that seems crazy compared to the gaming vid we see above that shows a mere 45 mins less while streaming video and 3+ hours of pubg. It can't possibly be as demanding to refresh a web page at 150 nits. Judging by the video as well brightness looked easily over that level. So guess we'll have to wait for the IRL user reports

I am really finding very minimal difference in haptic motor between the OnePlus 6T(my friend's) and my 7T. But I can say the loudspeaker is really good on the OnePlus 7T.

Thanks for posting that, what was the average screen brightness, ballparked if you dont have gsam style breakdown? Those numbers look better than the 7 pro! This usage mirror's my own, in that i dont do a lot of high cpu/gpu intensive work on my phone, aside a quick few photo/vid edits maybe. No gaming, so overall SOT for emails, msging is important. 8 hours bests what ive got on my 6T on auto brightness.

SS or it didn't happen

I've had this phone 2 days and so far I've had 6 hours 31 minutes of screen time and I have 58 percent battery left. This is mostly YouTube, Web browsing, an hour of downloading apps from play store and a bit of emulation (ppsspp) am extremely impressed with the battery life on this phone.

Battery lasts more than 2 days at Medium Power Saving mode with moderate apps usage(no gaming but with youtube, magic fluid live wallpaper, whatsapp, browsing) and SOT approx 13+ hours in these two days. At the end of second day battery remains at 30-35%.

To come back on it, I have it since today and so far it's looking like the G8 Power has better or equal batterylife, standby drain is somehow bad on the M51, I checked all apps. Still I'll let the software settle and get through more cycles and check Gsam Battery Monitor in a couple of days again.
I honestly blame Samsung's other apps that aren't used and aren't able to be disabled or uninstalled.

Hi guys. I wanted to let you know my findings and provide some test results of galaxy m51 battery life. Firstly, I will outline what was my priority for that test. I wanted to check how long the phone can last mainly on google maps navigation with additional apps in the background. Also this test is a bit static so to speak but had no chance travelling for so many hours. That said I believe SOT was tested correctly for my planned usage. I guess in a real case scenario, I would need to do some more browsing and perhaps occasional screen switch offs during a break like filling up the fuel or stop to rest on a bicycle.
How I performed my test.
1. I did some initial installations, downloaded my apps and logged in to social apps such as FB, Spotify so they can work in the background, send notifications etc.
2. Once I completed the setup, I charged the very new phone to 100%. AccuBatter reported capacity was 6800mAh designed capacity not 7000mAh and estimated capacity 6700mAh.
3. CPU-Z reported Snapdragon 730 so I regret it is not 730G and honestly I do not know how to check with online stores as the packaging does not help with this. Also, I plan to test POCO F2 PRO 8gb ram/256gb version the same way and see how it goes since I get better hardware, but I like SD card slot on galaxy m51. Very useful when resetting the phone.
4. Set google maps navigation, lunched another app which uses GPS and LTE for maps showing speed cameras, road works or dangers which I use alongside with google maps. I also start shuffle play on Spotify to imitate streaming the music in my car or on the bike.
5. WiFi, LTE, GPS, Bluetooth, sync was enabled, blue light filter enabled.
6. Between 15-20 apps were in the background.
7. I unplugged the device from the mains.
8. Initial 15% discharge was with a WiFi connection with my router. Then switched of my router for overnight, left wifi enabled on Samsung but it had to continue downloading data over LTE such as Spotify music streaming. I also changed google map setting to day light only to avoid night backlight.
9. I went to bed? and in the morning there was still a lot of juice.
10. Around 20% discharge I took about 100 pictures most of them in burst mode to simulate a trip where you simply stop and take some snaps.
11. I stopped the test at 1% discharge and noticed no heating problem. The phone was cool during the test.
The overall SOT measured until 1% discharge was a staggering 17h 50m? Below you will find AccuBattery screenshots. At remaining 15% I had still over 2 h 42 m of use left.
This phone reminded me of good, old days of my Samsung galaxy s3 with a Zerolemon 7000mAh?
Now with my galaxy s7 deteriorating battery (current capacity just over 2300mAh) this is a great thing. For Galaxy s7 I also own a KiwiBird powerbank case of 5400mAh right from the beginning wich did its job when away from the mains, travelling etc.
I guess for a more accurate SOT, I would need to add some phone calls and browsing but even with I deduct 2h, it is still nearly 16 h of use. Like for me excellent. I also do not plan gaming.
On the downside of this phone it seems like my galaxy s7 takes a bit better picture, but it just might be my perception of selfies taken. Back camera is also just ok on a cloudy day. Ok but that is an offtopic.

I got my M51 yesterday and I am not fully sure yet about battery lifetime. I have charged it to 100% and about 8 hours and 2.5 hours secreen time later I am at about 90%.
Coming from my Moto Z Play I am not sure yet if I stay with the galaxy. The Mot Z Play with Incipio OffGrid Wireless Power Pack mod is about the same size and weight. Though provides less capacity (3300mAh phone + 2200mAh power mod) but battery lifetime still was bout 3-4 days usually.
The M51 is also getting considerably warmer during use.
I noticed also the Samsung battery saver with medium settings can reduce the CPU clock to max out at 70% which is handy. Not sure if there is any undervolting, underclocking tools as I think I would be perfectly fine with less performance - actually I was able to reach insane battery life on my old Galaxy P1000 with TricksterMod and custom undervolting back in the days.
I still believe better lifetime with the M51 would be possible bz reducing CPU clock and also with better screen brightness control. I noticed many times already that the M51 screen was too bright for me and having to reduce the slider to "minimum" position or very close to it. Also I noticed that the screen brightness slider is not linear at all. So on the last notch on the left side the screen really starts to dim properly while to the right there isn't much change. Also I like still to use automatic screen brightness adjustments but found the automatic adjustment often moves the brightness too high.
Also a possibility to limit the used screen area (e.g. display black bar on bottom/top) would save energy on the AMOLED screen while still providing more than enough screen space.
EDIT: One-Handed mode sort of provides this feature, but not exactly what I was looking for (like cinema-bars on top and bottom and no prominent "one-handed-mode" title.
I will continue to use the M51 for a couple of charges and decide if I am going to trade it again. The phone itself is performing well, supporting VoLTE WiFi calling but seems to lack carrier aggregation for no apparent reason. I strongly dislike the slippery, fingerprint-attracting, cheap-looking plastic backside of it.
I also hate that everywhere you tap it tries to sign up to a Samsung account. Also replaced the launcher with Nova launcher.

Below is the answer to almost all above useless posts
Battery life tests - GSMArena.com
Why I say useless ?
Simply. SOT will be completely different when you read ebooks compared when you watch movies or browse Internet.
Gsmarena does standarised comparison
I am fan of long life battery phones. I used "king" Lenovo P2 for over 2 years. M51 is better.

I'm at the fourth cycle of charge.. and got 15 hrs so far.. have done a heavy idb debloating
maby it will increase over more charging cycles?
