Galaxy s7 (Exynos Dual sim - 930fd) root and rom recommendation - Samsung Galaxy S7 Questions and Answers

I switched from a Lenovo z2 plus to a galaxy s7. The switch has been a mixed bag till now.. i enjoy the camera to the core and the amoled screen..wow.. the main thing that is bugging me is the battery life i does not even last a full day and im not even using it heavily. the z2 plus used to give me a 1.5 days life on medium usage(official lineageos 16).
Could someone point me to the best rom out there(i dont mind the version) in terms of battery life.. i dont mind taking a hit on the performance.

I'm happy with the battery life and the overall experience on unofficial LOS16, but you lose all the stock Samsung apps and camera. The thread seems to be a rather mixed bag of issues and bugs, but it's largely been flawless for me.

is there any rom that allows me to keep the camera performance intact but get battery ?

imo the GCam ports quality is on par with stock, but they're rather unstable and tend to freeze and crash.
Otherwise I haven't used any Samsung based ROMs since Nougat, so I can't say myself which are best for battery.

There are many other ROMs to choose from just check the development section of the Samsung S7 thread.

official lollipop vs cyanogen mod 12

which one is better the offcial firmware of lollipop or cyanogen mod 12 for s4 ?
For me definitely CM12. Why? You have clean Material Design and clean soft. ROM is faster etc. But if you like sammy Camera and sammy sensor functions you should stay on official rom
Obviously Stock. It contains every feature

Whichever suits you best
(IT IS MY PERSONAL EXPERIENCE WITH CM AND STOCK ON I9500 I DONT KNOW IT IS TRUE ON I9505 OR NOT)
CM is a lot faster and smoother with a lot of customization that is very functional for everyday use and stock doesnt have it at all
I prefer CM for everyday use on my phone (I regret why I didnt buy a google play edition or nexus series)
but
something stopped me to migrate to CM
all version of CM on I9500 having heating issue because of charging current is high (usually 1900 mA) all the time but in stock when screen is on it is 1200mA and off its 1900mA
and it cause heating problem in CM ROM and ruin the battery life for just 8 months
in my experience when flash any of CM 12 (europhia resurrection pac man omni or any other) and use device while charging it the device temperature going up as fast as possible until u need to go hospital for your injured hand and then go to Samsung shopping center to buy a new battery

Any S6 user happy with their phone?

Hi guys, I'm going straight to the point: are you happy with your phone (in general, I know every phone has some minor annoyances)? I keep reading on the internet people that keep on lamenting about it (bad battery, laggy, awful RAM management, ect.), that's why I've opened this thread. I don't have the phone and I plan on buying it (it or the s6 edge or edge+, still have to decide - unfortunately the note 5 isn't coming to Europe anytime soon -), but all the reports are making me scared of buying it.
I'm happy with it. But you enjoy it more with root. Custom kernel fixes the ram issue, keeps the system speedy, custom roms add more features and debtor for better performance and ram management. So I'm basically enjoying it because of root

Like osmosizzz above I can say that I am very happy with this phone. Once you root it and remove the bloatware this thing flies. Using a custom ROM and kernel I have better battery life, endless customization options and a speedy UI experience.

I'd like not to have to root, I'm just tired of it (coming from a nexus 4), but I guess I might consider it if I buy the S6
You really dont have to have root as the phone is still plenty fast and with each update that comes out they are improving the software of the phone.
It's the best phone I ever had, my only gripes are aggressive memory management and the placement of the speaker (I usually end up covering it when holding it ), lag and battery are a lot better since the 2nd 511 update, the first update from 501 was rather laggy
I have 2 of this phone. here are my opinions:
1st phone (rooted and on XstrestoLite ROM)
I have great battery life, responses and everything seems fine except for the current bug with BOGG firmwares, which resulted in the keyboard lag when coming for lockscreen (Keyboard open delay about 3-6 seconds) check out my battery life here and here
2nd phone (stock and not rooted ever)
I find that the battery life on this phone not as great as my 1st phone, but however, everything is pretty smooth and great to me. But for a short time i had problems with GPS not being able to lock properly on Waze and Google Maps, however, not sure what happened (i didn't update the phone or anything) but it was back to normal again. and never happened again ever since.
Verdict: i love both my phones, i'll have them only until the Samsung Galaxy S7 comes out.
I owned this phone for over 4 months now. It never lag and blazing fast, the fastest android phone I've ever seen and the most amazing design I've ever seen too. It is just how the poor memory management kills apps at the background when you doing heavy multi-tasking, I've heard the 2nd 5.1.1 OTA fixed it. If multi-tasking is your concern, you should consider S6 Edge Plus comes with 4GB ram.
The battery performance is above average, imagine when you got this ultra smooth speed plus 2K screen and with only a 2550mAh capacity, I'll say it has done the job pretty well on battery life and enough to use a full day for any light to medium usage user. Heavy user will need a 2nd charge but it supports QC2.0(just get a QC2.0 powerbank) or wireless charging.

External storage can be overcome easily with this cute staff.
Since I'm a one-hand lover and the S6 size is the max. acceptable limit to me. I'm thinking to swap to Sony Z5 Compact later but that's s810 cpu overheating issue scared me away, I may just stick with S6 until S8 out, still not decided yet atm.
Its pretty good, but the RAM management and the occasional battery freakout (background drain) are irritating. If 5.1.1 fixes these 2 issues, I'm gold.
Before anyone tells me I can custom, its a work phone, I need full stock unrooted/knox intact otherwise I can't hook into my work's MDM systems (yes, its really nazi security).
But even without root, debloating via package disabler pro/debloater makes a noticeable difference to battery, which is a poor indictment of Samsung (6th generation Galaxy and still not learnt their lesson?).
The camera is out of this world and you get REALLY used to having a reliable fingerprint reader, I just rest my thumb stupidly on the home button on other people's phones (and if there isn't a physical home button I just stare stupidly at the screen for ~2 seconds lol).
I've never actually used the 'swap battery' feature so don't miss it, work phone so I got the storage bumped but if I paid for it myself I'd probably be irritated at the cost
One happy user here.
Battery life, my only gripe. Otherwise a perfect phone for me. Won't be rooting, just changed the launcher (Nova prime) and Skinomi case. Happy S6 user here!
apart from the camera I don't like any thing about this phone.
Best phone i,ve ever had,fantastic camera/screen/battery lasts me a full day no problems at all
Unhappy user here; bad battery life, laggy software, agressive memory resulting to bad multi tasking; will definitely change the phone.

I'm quite pleased with it, and I didn't even root mine. I'm especially impressed with the GearVR.
Count me with the happy owners!
I will root soon anyway to get more flexibility and customization.
Since updating to the EVR firmware (for network specific settings) I love it, super fast and great performance even with intensive games. My one issue is battery life; although it lasts the day with ordinary use it does drain after a while of continuous use, but then again with fast charging I just plug it in for a few minutes and all is good.
Is there any fix for the memory management?

Only thing I dislike about this phone is the battery, but as other have said. Root->custom rom + kernel (and MAYBE soon Xposed) and this phone is at least average in battery life.
If you don't root (and is a power user, the phone is not for you). With root + custom rom + few tweaks I can go around 3-6 hours SOT on data (depending on brightness) and 6+ on wifi. Without I barely hit 3.
Phones like the Xperia Z3 compact can hit 6 hours SOT without root. So yeah, if rooting this phone is great, if not it sucks from a power user perspective.

Latest 5.1.1 has fixed it.

Best & most stable custom rom?

Hi!
Currently with Moto E 2015 model. Really happy with it with custom rom (really good battery life: 2-3 days with my normal use and phone is rock stable).
I thinking of getting Moto G 3rd mainly because the camera (I need good quality photos in my work and don't want to spend 300-500 euros for phone).
Are there really good quality roms for this phone? I tried to look but everyone seemed to have some issues. Mainly I need to have it stable, good battery life and camera should be working fast. I don't like official roms, I want to root the phone, have tasker with automation etc.
Really appreciate any help and replies!
I suggest holding off for now as the camera quality is worse than stock in all custom roms (the MM ones, at least) right now.
Battery life can be made better than stock by tweaking the kernel.
All major roms are stable though. The CM based roms have only one noticeable bug (it shows 'Invalid Number' when the call is disconnected from the other side)
For me the most stable ROM with the best battery life is AOSP-CAF, but it doesn't have nearly as much customization as other ROMs.
I don't think there is a "best" Marshmallow custom ROM yet, and I don't think there will be until CM13 for osprey is in the official nightly stages.

Do custom kernels significantly increase battery life?

So I just picked up a pixel 3 and the battery life is fairly mixed but I guess I was spoiled with my previous device (Oneplus 5).
Will installing a custom kernel improve my battery life? I haven't really bothered since my Galaxy S2 which was a shambles.
If so, are there any specific kernels which aim to do this by default?
My opinion is that this is all imaginary.

A custom kernel typically gives you the option to customize the way it behaves. Increased battery life will come at the expense of performance. But even then you won't see a major difference. The biggest battery killer is poor cell service. Also, eliminate apps that run in the background, at least the ones you don't need running all the time. Screen brightness is another large battery user. Google does a pretty good job of optimizing the kernel out of the box.

They used to, quite a bit. But most of that went away with O. There just isn't that much left to optimize anymore. Now they are about extra features.

Debloated & Fast & Good Battery Performance Rom

Welcome,
My S7 started being lazy recently. Everything is much slower and the battery performance is tragic. Accu Battery says it's 64% so I think I can still use the actual battery for some time.
But... I'm currently on stock 8.1 but I was wondering if I would install some custom ROM like Lightroom or Lineage OS - would it be a good idea?
The most important would be for me to make my S7 fast and improve the battery performance. Also, the banking app & google pay should work (I will fix this with Magisk I guess).
Any ideas? Is this worth changing?
