Battery Duration Marshmallow VS Nougat - Samsung Galaxy J7 Guides, News, & Discussion

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.

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 statistics - X800

Hi. I created this thread so that we can all share our battery stats and comments on how battery life can be improved.
I've been using this phone for 6 days now and i can honestly say the battery life isn't great!
I noticed that during use, the battery % will go down by 2% instead of 1% like every other phones do.
Below are my current stats. It didn't even last for 24 hours!
FYI - i am on CN ROM EUI 5.8.017s (not rooted)
Battery life on this phone is just ridiculously awful!
my battery life is awfull
I've tried a lot of different things but keeps being pretty bad , the one that got the best result was setting the CPU to a lower frequency , but that only gave like half a day more.
Agree on the low battery, must be a combination of the processor + the 2k screen
With Android 6 update, I have not noticed any battery duration improvements. Is it possible LeTV has not 'activated' the doze option?
The Duration and good, I do most 3 hours of screen, which uses settings? app?
the battery duration is not very good if you will be using the phone with screen on, you will have a max of 5-6 hours, with full light a max of 2-3 hours.
But if you use it normally, not heavy, it will go throught one day

Battery life: CM13 vs Stock

Hi,
I'm wondering what others are seeing with the battery life of Moto G4 on CM13 vs stock ROM.
I'm a light user ( a little bit of email, browsing, some apps). Overnight, I lost about 3-5% of battery life on stock. So, I can go a week before charging. On the other hand, with CM13 I'm losing 15-20% overnight. Most of it is due to Android System and Cell Standby. So, battery life drops to 2+ days.
Are people seeing similar loss or is it just me?
Thanks

AEX rom with moun kernel
Dunno, I'm on Liquid Remix Pie and so far i like it. It has ''enough'' customizations. I'm using Moun kernel and with average usage I'm scoring around 4 1/2 hours of sot with 40% battery left which is in my case close to Stock sot (this depends on each user individually)

Can you send me your battery usage graph after a normal day? I already downloaded this rom but I had battery draining issues before so I want to see if its good now or if it isnt good enough

Abnormal Battery Drain on MIUI.eu 12, can't find the cause

I have installed MIUI.eu 12 on my Redmi Note 7. Using GSam Battery Monitor, I get 3.2%/h of battery consumption, SOT = 2h41. Most app that consummes energy is system. In the details, Significant Motion Detector consumes a lot of time.
Any way to correct this behavior??
Thanks!
I am also facing this issue after updating to miui 12
Same problem here! Often battery consumption reach more than -750mAh (even -1200mAh!) even when I'm just scrolling homescreen!
What about yours consumption when screen is off? Mine are pretty good, like around -0,5% per hour.
