For those getting +5 hours of SOT, what are your current ROMs and kernels?

Also, how's performance for you?
I'm running a build of Exodus 5.1 with the boeffla kernel, and I'm getting around 3 hours SOT from 100% to 0% battery. That said, I have it set up in a way where I have zero lag (not using performance governor) and I'm getting 76206 on Antutu. with. I've also got Greenify and Amplify.
Just as a side note, how is your charging? I'm getting around 200mAh in (from my best cable and charger) boosted to around 650mAh using boeffla settings. Isn't that a bit low?

Atleast for me and my OPO, only the original charger and cable gets reconized as AC Charger, everything else i plug in as USB Charge, thats why the chip is force values around 200-650mA.
Boeffla Kernel can show u that, if the app says "Ac Charger" + a mAh value then u'r good, if it's not and just shows only a mAh value instead, the Cabel and Chager are reconzied as USB Charger therefore the IC Power Chip limits the throughput.

Sultanxda's 5.1.1 caf rom. Can easily bit 6-7 hours sot. Stock kernal
Before switching roms you should try wakelock detector and/or better battery stats to see if something is keeping your phone awake and killing your battery.
I don't worry too much about benchmark scores, focus on how your rom runs for everyday usage. Performance is just fine for me, but I don't play any heavy games on my phone though

Stock ROM and Boeffla Kernel, 6 hours of SOT with a battery friendly configuration (light undervolt, small underclock and balanced governor), but performances are still great with no lags. However with the stock kernel I never went below 5 hours, which is already a great result

used to have 8h SoT on KitKat. any lollipop / MM rom gives me max. 4h.

Darkobas best battery for me. Around 6 hrs. Then Herna's Omni and RaCyan: more than 5hrs.

slimsaber 0r Omni 6.0.x and sultan CM 13 06/12. CM 07/12build all giving 5+ hrs SOT for me.

I got about 5.5hrs on data (mostly LTE) yesterday across about 14-15hrs usage.
Sultanxda CM13 rom. Everything stock. No greenify and amplify and stuff. Turn of keep awake and wake up for google play services.

recently switched back to kitkat after realizind nobody was gonna fix the sitty battery life on 5.x and upwards. Not regretting my decesion. Bear in mind this is a one and a half year old phone that has seen daily usage, almost half of it was on 5.x, waiting for a battery drain fix. When it didn't come, I came back to 4.4.4 and I'm happy to say my battery is still healthy (was a bit worried all those months running a battery draining rom would have strained my battery). Cant tell you anything about charging since im using stock kernel on official CM11S with a stock charger, other than the fact that it charges really fast. Performance is so good that i decided to try and undervold (to 1950~) and im seeing no noticeable difference. Device is nice and snappy. I'd wholeheartedly suggest a switch to kitkat for the time being for anyone that wants to max out battery usage.
Note: These screenshots were taken after only the 2nd battery charge cycle so the battery still isnt calibrated all the way. After a few more charge cycles, i could probably get back to what i was used to on kitkat in terms of battery life: namely 8h screen time.

My phone running on stock COS12.1 and can get around 7-8 hours of SOT with WiFi in 1 day usage. On 2 days usage SOT 5 to 6 hours. But on Mobile Data I getting a 4 to 5 hours of SOT. For charging I using Apple's wall brick from old Ipad and original OPO cable - 0 - 100% in less then 2 hours.

Sultan cm13 nov build. Getting constantly over 5hr sot with LTE. Standby time 12-16hrs.
Disable the wakeup for google play services.

I'm on sultan's 01/01 cm13 build. Currently have 1:43 sot and am at 78%. Was at 92% after upgrading. So that's 7.357 minutes per 1% battery, or 12.26 hours SOT. Wakelocks are not an issue here because this is continuous use on about 30% brightness, wifi and lte on, sync on, Web browsing and YouTube only (no gaming). Completely stock build with no power saving bs. Sultan for president!
TLDR; depending on your useage, 12 hours SOT on cm13 is possible.

4.4 with cm11s

I've never had more than 2 hours SOT with any rom (stock, sultan's caf, exodus, and others), do I have a battery problem?

5,5-6h SoT with Fusionjack's SlimSaber 6.01 which is based on OmniROM Sources. I'm using this ROM without any modifications, like custom kernel or xposed, neither i'm using things like greenify or similar. I've just tuned the power profiles to save battery while screen is off and limited max cpu frequency to 1958MHz to prevent heating. I'm using Facebook+Messenger and WhatsApp, which are by far the biggest battery hoggers and running Google Now with on Tap with GPS at hight accuracy the whole day. So the reached SoT is absolutely nice. Calculatory that would mean, without Facebook, WhatsApp and deactivated GoogleNow and GPS i could easily reach 8h SoT, but i prefer the comfort over the battery life, coz that's why i'm having such a smartphone.

Sultanxda CM12.1 rom w/ the kernel it comes with. With LTE/WiFi mixed use all day, getting 5-ish SOT and 24 hours battery life total. Installed Greenify but have it limited to hibernating 3 apps only. Likely going to fool around with profiles to see if I can squeeze an extra 3-4 hours out of it.

Hi, I'm running the same setup as you, I was just wondering about the level of screen brightness you are using? Is your phone running on full brigthness, 10%, 50%, 70%? And are you using apps like greenify, nap or anything similar?
I'm getting good battery life with your setup but not as good as you. My screen brightness is always set to full and I'm sure that could drain my battery faster. So I'm just curious to about what level of screen brightness everyone is using approximately to get these kind of great screen on times. I'm just super impressed and hats of to you and everyone who achieves this lenght of usage!!

I got best battery with Darkobas, but my best is around 6. It depends on alot of things: your battery, your signal, your usages... I think my battery is old and the signal here is weak. So you can only compare to your battery life with other roms, other kernels...

I definitely understand that and the factors there is. But I was just wondering if those who are receiving 6+ SOT have their screen brightness turned down or if their screen brightness is fully turned up.

Battery Duration Marshmallow VS Nougat

Hi guys let's share our usage experience about an interesting theme, battery in roms so we can chose more wisely.

Mi experience: supernova light - 10% battery usage gives me 1h30 screen on + WiFi.
Supernova nougat - 10% battery usage gives me 1h10 screen on + WiFi.
I stuck withe Supernova light because battery difference is huge.

Real vs test battery life

Hello guys,
I own an Exynos S20 for a month now and I'd like your opinion on tests we can see on the web that seems legits.
They all show comparisons with other phones etc, and it seems that the recent ones show great battery life on our Samsung s20s.
In fact they show 7 or 8 + hours of SOT and S20 results almost even iPhone 11 pro results.
As far as I'm concerned, I don't have anything near these results as I never went above 4-4h30 SOT on my S20, even if a optimized my settings, got rid of some bloatware, or even set up routines to save some battery. Plus, I'm stuck at home so 100% of the time on wifi.
Do you think these tests are false ?
Thank you for your answers or advices.
Best regards,
Thomas
Here are some links of tests I speak about :

All right, thanks. But this is not on a full charge is it ?
You charged the phone on the middle ?
Still, 7h30 SOT estimated would be great for me. ^^
Could you pls share your optimizations/settings ?

No this isnt a full charge of course. I don't use the device such frequently, it's only a calculation from the app "AccuBattery" which is based of my usage statistic since the last 7 days. What I can say is that it needs 5-7 days till the battery life was okay. Also with the last two firmware updates my estimated SOT raised from 6.3h to 7.1hours. (maybe it is a coincidence)
Realistically I would say (without gaming) I will get 6/6.5 hours out of the device if I stay at home. (So the screen brightness isn't as high as outdoors)
My settings:
- FHD 96hz (you can find the app here in the forum)
- GPS off (don't now if it makes any crazy difference)
- Bluetooth, mobile data and wifi on
- energy setting set to optimized and adaptive
- put all apps to deep sleep (except WhatsApp, Gmail, smartwatch app)
-> you can find it in the battery saving section
I think it will not make a big difference if you have your screen constantly on)

I to wonder about the sot some people get....I get +- 4 to 5.5 hours sot on a good day....most days 3.5 hours....I did notice that 4g/lte drains a lot more power then wifi....the bad sot days are the days when I'm at work and only on 4g/lte....AOD etc is on and I use most of the functions the phone has...120hz etc....Why buy a phone and not use the stuff... I can get through a normal day fine, so I'm okay with the battery...The standby drain on my s10 + was bad...during the night 2-4% per hour....the s20+ I get .5% per hour during the night....

A good stable rom for battery backup?

Hi all
I thought I'd ask the experts about what are in your opinion some good roms for battery backup?
I'm currently on stock MIUI Global 11.0.5.0 (PFGMIXM) but I'm not much satisfied with the battery backup (5-6hours SOT).
I need some stable firmware since I use my phone mostly for work, no gaming, no social media, just phone calls, messaging and some light youtube usage.
Thanks!

Ion OS is brilliant, especially for battery - sourceforge.net/projects/i-o-n/files/device/xiaomi/lavender/ Around 10-11 hours SOT.

Anyone can compare MIUI vs Xiaomi.eu VS Pixel?

Miui right now just being laggy and jerky sometimes with animation, thus pixel based cutom rom just some having like miui and some is dont. I prefer evolution x on latest build, which smooth operation per my multitasking usage(on stock kernel obviously), whilst the battery just doing better other than resurection remix, pixel experience etc.

Could you be more specific about how long the battery lasts, I mean that if you are using your phone for like 4-5 days then 5-6h of SOT is quite normal for this phone but if you meant just one day then it should be about 10-11h of SOT as there will be less energy consumed by things like cellural network.
I had pretty good battery backup with POSP by AmulayaX but i found out that slow-motion isn't working so i switched to StagOS (unofficial EAS by Jimgsey) and i like this rom but i have some small issues and i consider switching to official.

5-6h SOT in 2 days. I'm not playing games I only use my phone for calls, whatsapp, emails and web navigation.
I'm on dual sim though.
I could never achieve 10h SOT in stock. Any hints for some good rom that can do that?
Thanks

Someone already suggested you to try Ion Official for Redmi Note 7 as it is EAS & feature rich also. But for more you can try Bliss ROM as well. Last but not the least LineageOS 17.1 Official. I'm currently using Bliss ROM. It is the best in all others upto now i have tried.

U can't reach 10 h SOT by 2 days on battery.
Calculate 0,5 %/h idle drain
2 days 48h - 5 hours Active drain = 43 h idle time
43 x 0,5 = 21,5 %
so round about 20% battery is lost in idle time
so 80 % for active drain.
Charging battery at 15%
80-15 = 60% left for active drain
On mostly all roms i tested i get an active drain by 10% per hour
Wud be for u 6 hours SOT
Seems normal drain with ur MIUI
But aosp roms are so much faster and mutitasking so much better compared to MIUI.
I only got 3 GB model and there no way back to MIUI

I gave PixelE+ a try but I'm experiencing less battery backup than stock (and some random freezes too).
I'll try ION or Xiaomi.eu in the coming days.
Meanwhile what about changing kernel? Any good recommendations please?

for me changing kernel isnt a game changer
its all about SOT, screen brightness for sure and good working deep sleep.
Screen is biggest power consumer.
Kernel maybe change covernor and undervolt cpu. sure this brings a lil power. but trust me it makes just a very lil differece. u cant compare ur drain because ur usage isnt same.
if wanna judge a kernels power consumtion u have to do all the same.
watching 2 hours youtube, play same game aso with same screen brightness with same wifi state aso.
i bet theres no "big" difference.

I'm currently on Pixel and I can make 4h SOT in 2 days. I don't play games or use YouTube. Just phone calls, whatsapp, browser, emails and I'm always on dual sim.
With stock MIUI I used to reach 5-6h SOT in 2 days so with my personal usage Pixel is worse in battery life compared to stock MIUI.
I'm thinking of trying something like Xiaomi.EU now since it's based on MIUI stock...

As i say, for me there are just few differences in battery life from rom to rom.
Miui is slow and bloated compared to non miui based custom rom.
When u just installed new rom u have more drain cause of trying out the rom. U have more usage compared to ur old rom. Lets get rom settle for a while before judge.
At least all rom take power. All rom need display. I think display always takes same power in every rom when u got same brightness.
At home in ur wlan mostly watching YouTube u get better battery (maybe under 8% per hour drain maybe less) than navigating in the sun with mobile data (cost 12% per hourand more) battery

I'm with you however I'm currently on Xiaomi.eu 11 (debloated) and battery backup is much better than Pixel. I hit 6h SOT on the first run, expected to improve in the coming days after a few charging cycles.
Same usage, the exact same apps running.

Stand-by battery life with custom ROMs is bad

In the same conditions (no SIM, no WiFi, no Bluetooth, no NFC, fresh reinstall) using the latest available MoKee ROM and the latest available LineageOS, I get 1 hour of stand-by autonomy for each percent of battery capacity. But using the official 4.4.2 ROM, I get like one day for 6% of battery.
Battery life while watching a video on LineageOS was OK though.
I guess the custom ROMs lack some Samsung deep sleep stuff? I also have a Galaxy Note 8.0 (the tablet) and it has astonishing stand-by autonomy.
Is there something I can do to improve stand-by autonomy of my Note 3? Thanks.

you can use another kernel or you looks at "Tweaks" - Manager for your Note 3.
Here can you change the Settings for max/min CPU, Deep Sleep and another

Well it was the NFC, I thought I had it disabled but it was still active. I seem to be getting a stand-by battery life similar to that of the standard ROM now. I didn't think just having NFC enabled would consume so much energy.
