[Q] How to use ROMS/Kernels for Battery life - Galaxy S 5 Q&A, Help & Troubleshooting

I just bought an unlocked Samsung Galaxy S5. It's pretty nice and all except the battery life is terrible. I tired to do it by turning things off, but then I was just left with a boring that can't even do anything. What's the point of all it's cools stuff if you have to turn it all off just to keep it alive? I heard that after rooting a phone one can download custom ROMS to improve Battery life. My problem is I don't have a single clue on how to use them. I've tried Omega, Waman, Alliance, Cyanogen and others but I don't know how to use any of them for battery life.
Is there some sort of tutorial for using them? Or anything at all that could point me in the right direction? I'm so confused I think I'd rather just buy and extended battery.

How long does your battery last? Maybe your expectations are unrealistic
I recommend you to flash an AOSP based ROM and install Greenify. Maybe you should also flash a custom kernel for tweaking your CPU.
Furthermore you could buy a new battery

Battery issues

Is anybody else facing this issue?
Gesendet von meinem Nexus 4 mit Tapatalk 2
Nope, my phone is in English haha. In all seriousness, what is the problem? I was never good at those spot the difference puzzles...
Edit: was your phone plugged in that whole time? damn! I've had some battery calibration issues, going to let it run dry tonight and stick the charger in as it's powering off... seemed to solve any battery calibration issues on my previous android handsets.
Yes !
... it was plugged in the whole time. It happend to me 4 days ago aswell.
When I had CM10 installed I thought it was an issue with the ROM but
it feels like there are much bigger issues on Stock.
Do you think it's useful to wipe the battery cache?

Battery drain even in deep sleep

Hello folks,
I'm facing a battery drain problem when the Tablet is idle. In the last week i managed to get >11h Screen on Time and awesome idle battery stats. But now my battery drains even if the device is in Deepsleep with Wlan on and Synch on (>97%) about 1-2% per hour. [With Gnow off, Bluetooth / GPS / NFC off). The curios thing is, it happens with all Roms I tested so far, when I'm replacing the stock kernel of the rom with the ktmanta Kernel.
Can you guys give me an advice ? If there were wakelocks which wake the Device i would know what to do, but with Deepsleep > 97% ? The only Wakelocks are gmail and google account synch.
I would be thankful for every Hint.
Best regards

This most likely and issue with the kernel. If your kernel supports underclocking you should consider doing that because underclocking uses less battery. With all that stuff off and ONLY wifi on, during sleep you should not lose more than a percent every couple of hours. I have kept mine stock but im well aware that most battery issues are relating the kernel. I have a nexus 4 and Gnex before that both rooted and used to run AOKP before but not CM 10.1. So I have seen enough battery issues to kno that this completely because of the kernel.
AW: Battery drain even in deep sleep
Okay, I'm aware that it has something to do with the custom kernel. But the weird thing is, that all was good and then suddenly after 3-4 cycles my N10 started to lose battery in Deepsleep. There wasn't any change in the rom / kernel or settings. If tried several Roms / kernels but only get rid of it, when I stick to cm stock kernel.
Atm I'm on the actual ktmanta underclocked @ 200-1400mhz + undervolted

If it is happening with every custom rom you have tried so far then maybe it is time you try a new kernel. Also, this might not be it but just to be on the safe side, check what apps you have running in the background. Might help.

[Q] Best Stock Rom regarding Heat and Battery

Guys, i have an octa core S4, and i've read everything i could find in the forum about it, and i even have tried many stock roms and i can't decide, so i want some experiences.
I'm trying to find a stock rom that has good battery and doesn't heat up too much. I've tried:
MEA India - Best Result so far. Good battery, heats up quite a lot.
MF8 India - Eats up too much battery
MG1 India - Same as MF8
MG5 India - Eats up too much battery but stays quite cool.
By the way, the temperature measured in the CPU using the *#0*# code were (using MEA firmware):
20º-25º idle
25-37º while browsing through wifi
35-55º while heavy gaming
Now i don't know if these temps are normal, for what i've read in this forum, the browsing temp seems to be a bit high. On the other hand, the temp rose up to 55ºC only playing for 5 mins a very heavy 3d game. Is it normal for it to get heated so fast?
So far, i'm sticking to the INU MEA rom, but i'd like to know if someone has a better experience with a newer rom, but i want only STOCK ROMS, not custom ones. By the way, i've checked for weird process running in the background in every rom i tried and there was nothing suspicious.
Thanks in advance everyone.
Everyone's phone will react differently.

Yes of course because it depends on the use, but even when the phone doesn't reac exactly the same, the hardware is basically the same for every i9500, so the behaviour of everyone's phone should be similar, unless of course there's a defective handset
Best stock ROM is the Symbian S40... trust me.. you wont find anything more stable than that... :sigh:

How is battery in Android MM + Custom Kernel compared with LL + Custom Kernel?

Hello to all, how is your battery experience comparing MM+Custom Kernel and LL+Custom Kernel?... I'm still thinking if I will go to MM or not yet.
Thanks!
Actually wondering the same. Tagging along.
Battery with stock kernel is almost the same as in LL at much better performance and smoothness. With skyhigh kernel battery is bit better, but slightly slower. Since yesterday there is a new audax kernel out with good performance , still evaluating battery life.
The step to MM is worth it, you should upgrade.
Gesendet von meinem SM-G928F mit Tapatalk
Getting around 6hrs 20mins screen on time on MM.
Thanks for the feedback, I agree that MM is better than LL, battery a bit better with much better performance compared with LL.

Yesterday I also got 6.30h with Google now, location... I'm trying not to use mobile data. It sucks battery badly!

If you dont use mobile data buy a tablet...
I get screen time 4.30hs, more than enough for the heavy use I do to the phone. Don't install Audax Kernel because it drinks the battery.

What kernel are you using? In my opinion, Audax kernel is far better than SkyHigh
Performance is better with audax 1.0, with little bit less SOT

Skyhigh, Audax in my phone drinks the battery, why do you think Audax is better?
Audax has better Performance at the cost of battery ?

Best Kernel-Balance Between Battery and Performance

Which is The Best Kernel For you with Oxygen OS or OOS Based Rom's For Best Battery Life and Performance Balance?
I used FrancoKernel But I Don't know why I am Getting only around 3.5 Hours of SOT When others are getting 10Hours
In the Stock Kernel and OxygenOS I am Getting Around 4 to 4.30 Hours of SOT
well bud, you should know how to use a smartphone. there is no way on the earth that OP5 lasts about 3hours. No offend, you should consider switch to iPhone. Android is a different thing. you should know how to get rid of wakelock, what consumes the battery the most, or what keeping your phone awake etc. No kernel or rom can help you.
Stock, don't be fooled, there is no kernel that give you extra hours of battery life or rocket speed.. that's just placebo or bored users that they need to flash something.
Oneplus 5 is quick enough, apps opening instantly, to where you want to push it more?
Even if you find some way how you throttle down performance to gain couple of minutes on battery where is the point, when on the end you put
your phone on charger that in couple of minutes give you power for another day?
just enjoy the phone..that's my opinion

I Got your Point,Thank You for the Information
I Just Switched From Iphone 5S Maybe That's Why i have Devoleped this Laziness to Not to Look into Advanced things,I will Research more
I Used to Use Android in 4.0
There is something else that is draining your battery, such as an app, it's not the kernel
I flashed a lot on my elephone p9000. No need to on op5 stock experience is perfect
SimpleGX has very good feedback regarding battery saving and stock performance.
I'm currently giving it a try but it's early for me to comment properly.

What a negative bunch of responses.. I use franco, naptime and get 5hrs plus SoT easily.
You don't need to be a power user to have android. Stock is fine, but modded is better (this is xda after all).
Fresh install latest OOS, keep installed apps to a reasonable amount (which do you -actually use-?)
And then... Use. If you are a business user, expect less SoT. If you only watch YouTube on wifi, expect longer SoT.
You go and most importantly, explore! OP5 is a wonderful phone!

This or stock. I've tried all the other kernels (with a friend who also has a OnePlus 5). Stock beats everything else in terms of battery by at least an hour of SOT in daily usage, more if you use the whole battery in one sitting. Nobody seems to have a straight answer as to why this is. Simple gx stays close enough to stock that battery life is pretty much identical to stock. I have no idea why battery on Boeffla, blu_sparks, elemental x, Franco, etc isn't as good as stock, doesn't make any sense to me. Same results on 2 different phones, but ymmv I guess?
