[Q] ROMs that enhance battery performance?

I recently bought a used Sprint Galaxy S3, it is the SPH-L710 model.
It works great, I like it, I got it rooted with no problem, and got CWM flashed to it and I'm getting ready to flash a ROM.
I've been searching forums and sites for about 2 days for the ROM I want to use.
I'm mainly looking for something that enhances my battery performance, the reason for this is when I first got the phone, I updated it to the 4.4.2 KitKat when I first turned the phone on and the battery life was terrible, like I would charge it to 100% and use it browsing the web for about 10 mins and lose sometimes upwards of 10+% within that 10 minutes.
I searched around and found 2 Apps that I am using right now, one is a battery doctor type thing, the other is an app called Battery Saver (root) it changes some stuff and is supposed to make battery life better, since I have started using these 2 apps my battery life has increased, but it still seems to drain a little fast. So I would like to try and find a ROM that perhaps has tweaked the battery life.
Does anyone have any opinions on battery life for any of the ROMs here that would work for my device, like perhaps which one that you have tried that extended your battery life? I know I could just try them myself, but I am hoping to save a bit of time and see if anyone has some input.
Also another quick question, is there a way to test my battery and see if its just bad? A friend mentioned that the battery could have just gone bad so I'd like to check that if possible.

A. S3s aren't known for their amazing battery life. My battery does not go very far either, talking on the phone, which I do a lot for work, gobbles up the battery immensely. (Like 100% to 80% in 30 minutes.) Web browsing is another battery hog.
B. ROMs are only going to do so much as far as extending your battery life. Just bear in mind -- the lighter the ROM, the less battery it'll likely consume.
You'll do more to save battery by flashing a custom kernel on top of a light ROM that'll allow you undervolt/underclock. But, you want to make sure you flash the correct kernel to the correct ROM base (e.g. Touchwiz kernel for Touchwiz ROMs, AOSP/CM based kernels for AOSP/CM based ROMs).
I personally use the DKP kernel found here in the S3 original development thread.
Be careful w/ underclocking and especially undervolting, as this can cause the phone to freeze up. It's also important to choose a governor that has a nice balance between performance and power savings. (I like the freelunch governor.)
Hope this helps.

Thanks!
That gives me an idea of what I should start looking for, and I'll check out the DKP kernel as well..
I just thought of another question I had, maybe you can help me with it too.
Since I'm running Android 4.4.2 on my device, would I need to find a 4.4.2 ROM to flash?
For instance could I use a 4.3.1 ROM on my 4.4.2 device?

It doesn't matter which Android version you decide to go with. Just avoid two things:
1. Do not flash an older bootloader than the one you are currently on (e.g. If you are currently on ND8, do not flash any older bootloaders like MK5 or MD4).
2. Do not flash any modems older than the one you're currently on. Your modem version can be found in Settings -->About Phone --> and the last three letter/number combination under "Baseband Version". Hint: The baseband version also tells you which bootloader/ROM you're on.
Doing either of these, will trip Samsung's KNOX security feature, tripping the kill-fuse, and suddenly, you'll have yourself a nice hard brick.
I know that probably sounds intimidating, but I assure you if you avoid those two things, you can flash any D2LTE ROM you please. (D2LTE ROMs will work with the Sprint S3.)

idk man the batter life of my S3 lasts 2 days where my Infuse 4g would last less then one with a new battery.....so by far the best battery life I've had in a while

Wew! Thanks for that info, you may have saved me from a terrible mistake lol.
One of the ROMs I was looking at was using the MD4 bootloader, so that would have been a no-no xD
Thanks a lot for all your help, I learned a few things from it, epspecially about the bootloaders and modems having to match, I had no idea about that. Now that I know that, it opens up a few more possibilities for ROMs I can use!

Fun fact: The bootloaders and modems didn't always have to match.
Samsung wanted to be able to market their devices to business entities, and in order to do that, they developed the KNOX security feature.
Once it's on your phone, it's not coming off. It matters to corporate security policy people, because they want devices that aren't going to be compromised if someone tampers with them.
And, as you can see, the wrong kind of tampering makes the phone completely unusable and unrecoverable.

Right now I'm sort of leaning towards LiquidSmooth, Quantam4, or Tribute ROM, still sort of looking around though.
If you don't mind me asking @Higgs_Boson, which ROM are you using?
Also, to the other poster, my mothers GS3 is the same way, hers will last upwards of a day and a half, then again she doesn;t use hers for much, while I'm on mine like a computer lol.

Right now, I'm on CM11.
I usually switch between two that are my favorites:
CyanogenMod or Paranoid Android.
If you want an all-in-one, there is always PAC-ROM, which includes Paranoid Android, AOKP, and CM all under the same roof. (But then, we get back to that thing about light ROMs.)

I completely overlooked CM
Is CM11 compatible with the DKP Kernel you were telling me about?

yep
Yes it is. I'm that combo at the moment

personally yes after i replace the system UI with the Stock ND8/NDC one and same with the TW Framework and TWframework-res.apk and use the Stockish theme for it.....i like the stock look what can i say but im using xposed at the same time for little things here and there but if you don't want to replace somethings and want it to work 100% use the PCB theme that it comes with.......but either way its pretty smooth and fast and the battery lasts for 2 days with some gaming and listening to music with viper4android installed and making calls and texting the one thing that i would say drains my battery is watching videos but you'll be satisfied

Wow you arent joking. This is one of the best ive seen lately. Nice.

Wicked X, Tribute and Conquest Singularity are all 3 very good ROMs with pretty fair battery life. As stated, Kernal Settings do make a world of difference! I'm on Singularity with latest KT747 Kernal and love it :]

[Q] New LG G3 User here

So, I just got this phone about 2 days ago (After sending one back due to over heating issues) Anyways, I want to get the most out of my new phone.
So, I have a few questions I can hopefully have answered.
1). I want to know the BEST way to improve my battery life if need be and to avoid any type of heating issues since I am a heavy gamer (Order and Chaos, Brave Frontier, PPSSPP emulator)
2). What is the benefit to rooting my device? Will rooting my device void my warranty, and if so, if I were to unroot, would i still be under warranty?
3). ROMs and Kernels, are they stable? My last device was the Galaxy S4. Ran perfectly never overheated (Got slightly warm, even when hardcore gaming) though. When I installed a ROM (Wicked, Cyanogenmod Android KitKat 4.4.4) to it, it started to overheat from just going on Facebook or about 5 minutes on any game. Continued to overheat even after I flashed back to the Original Stock Rom.
Really loving this device as is right now but would love to learn some new techniques especially when it comes to heating issues or battery drains (So far so good, with the exception that Brave Frontier made my phone really hot earlier when on for about 10 minutes on 100% brightness)
Thanks in advance :victory:

Cyanogen - queries

I keep pondering whether to install CM11 and the dev work going on looks like its working well. I'm frankly sick of lag and the lack of smooth scrolling. I'm not rooted so I've not tried debloating it tbh.
However if I take the jump, is it easy enough to regress and reinstall kitkat/lollipop (when its ready)? I know it'll trip the knox counter but will reinstalling kitkat revert it back to OTA's?
I've been disappointed with Samsungs support of their top flight tablet to be honest. I keep being told bull about a fix is coming to address the lag and lack of smooth running but its not landed and I've now had 2 devices since July and they are as bad as each other.
thanks

Have you tried just using a different launcher. Like Nova.

Use nova and greenify. Greenify can hibernate apps so it can stop lag and save battery, it even works without root!

You should be able to revert back to stock without problems. Your flash counter will be incremented, but that's ok.

thanks will try greenify...is there a 'safe' list of apps to greenify ?

Pretty much every app listed in Greenify is safe to hibernate (unless you start checking a whole lotta checkboxes in the setings; in that case, you are expected to know what you're doing)
To be honest: I tried debloating, Greenifying, etc. all before, but even though they helped a lot, they did not get rid of ALL lag.
I can honestly say that I have been using CM11 for over a month and a half now and I still am very happy with the performance.
Batttery life is so-so, but ten again: I have forgotten what it was like on TW Plus, greenify recovers some of that battery anyway.
You should note that the CM11 development has somewhat died for the t700, which I personally think is really sad considering the age of this Samsung flagship tablet.
But the Rom and kernel that are available are pretty much bugfree as they are, so you can use it as a daily driver without a problem

Is like prerooted? How does it go? I know you have to install gapps and the rom itself but my question is about the root.

It is pre-rooted, so all you need is a custom recovery and you can start

New phone where to start?

Hi folks, I purchase a LG Nexux 5X and will arrive soon and was wondering where should I start modding it.
I have done several mods in other phones and on the gear 2 neo, so I know how to use odin and some adb functions.
I usually don't tamper with a new phone unless it is really slow or annoying me with some bug, but would like to know if there are some minor tweaks I can begin to tinker with that will enhance my overall experience with this phone.
Thanks in advance
Best Regards.

Getting my Nexus 5X tomorrow but currently use a Nexus 5. With any Nexus you want to start off with setting up the Android SDK and all the Nexus drivers on your computer so if something does go south, you are ready to fix it with the factory images. The first thing I am going to do with mine is put Android N on it since I haven't had the chance to try it yet. Then root and most likely be happy with that for a while. Since Android N will probably be officially released soon, I'm sure that's when a lot of stuff will start happening around here. Hopefully Xposed will get updated to work with it. If so, that will be my setup. Stock, rooted and Xposed. That's basically what I have been running on my Nexus 5 for a while now. But if you want to try out custom ROMs, there are those too.

Thanks for your reply. good advice to save the original rom image! I will probably root too, because I usually OC my phones hopefully that won't be so much a hassle.

If I were you, I wouldn't OC at all. Snapdragon 800 series likes to overheat and throttle itself, making it slower than usual.

I have the N5X for several months.
I previously had the N4, N5, and OnePlus One (still have it, wife uses it).
I used stock, I used to flash ROMs at least twice a week minimum (same on the other devices). Various ROMs, to test their performance, their tweaks, their perks, their battery life... you name it.
However, flashing ROMs and trying out various mods feels very much like living on the road with your backpack on, rather than staying at home and having a steady job. Because while flashing ROMs, you don't always re-install all the things you had (Even if you backup with Titanium Backup, as some things don't survive data restore very well). Last week I made the decision to go stock and stay stock (well, not really, I went stock Android N Preview 5, which will receive OTA to full Nugget in about a month).
I have to tell you... I don't quite feel any difference other than losing a feature or two. Speed is still great; snappiness is snappy, no bugs and no issues. It feels great even though its encypted (by default), while all this time I was certain being un-unecrypted made the device any snappier; that was just a placebo I guess.
So yeah, you can go ahead and flash a custom ROM (or many of them!), but don't do it for improved performance. Stock performance is truly awesome, and while some ROMs make it better, for sure - it's not THAT better, not in any noticeable way. Do it for features, do it for fun, do it for curiosity, DO IT! But just know the simple truth that Stock Android 6 and definitely 7 are so good and bug-less, that there is no need to get customized to resolve any bugs or performance issues; there are none.

Agree. I used to root and ROM the crap out of phones but with the 5X I've stayed stock. Yeah, I see more ads now and miss Viper4Android but I spend no time F-ing with the phone and all the time just using it. No gyrations to go though to install monthly security updates or trying to get banking apps to work with root (like Android pay). Try it stock for a while.

I was reading that thermal problem post, it does present an issue to me because when I ride a bike I usually have the phone on the handle in a rubber case exposed to the sun and the heat that can easily reach over 35°. Thanks for the heads up.

I hear you, I have prolonged the life of my smartphones more than it should, by tweaking and using customs roms. I have had only 2 other SP in the spam of 6 years and had never had to be subject to a phone/data plan. I just ride the wifis signal or pay per use the 3g signal. Even-thought this LG is not a big inversion in itself, I hope I can squeeze several years of it and the old practice of using custom roms, seems kind of pointless or not worth the trouble considering as you say the stock is as good.

Should I Root My 10?

So I've had the phone for a while, I am confident there are no physical faults and don't mind partially voiding my warranty. I've always struggled with battery life and ever since the Nougat update, my phone has been slowing down and experiencing some random issues such as very high WiFi latency and small 1-2s freezes.
Obviously a factory reset is in order and since I'm going to wipe the phone anyway, I was thinking I might root it as I have rooted all my past HTC phones; the only reason why I haven't rooted the 10 was because I was content with its performance (was) and I was waiting for Nougat, which I finally received.
Since the 10 might get Android O in the future, and it would be much easier to update over OTA, I was curious how everyone's experiences with custom ROMs and Kernels on the 10 has been? Have you experienced noticeably better battery life, performance, etc, what ROM/Kernel combinations do you guys recommend? Do you think rooting is a good choice?
Any comments welcome!

I root all of my devices but for specific reasons. I like to be able to remove unwanted applications and logging, I only want what I want running on my device. I also root to block ads with adaway, although there are alternative non root options now for this. Another benefit of root is modding, whether through a custom ROM or a stock ROM that you flash various mods to.
I initially ran the stock ROM rooted but soon found some limitations with the sd card.
A stock based custom ROM was the solution for me ( leedroid , but there are others ) . My battery life improved greatly and some mods do genuinely enhance the experience. Most roms have an installer that allows you to select everything that's installed, including kernel .
Another advantage for me is Titanium backup, the ability to backup applications prior to updating them and restore older versions of apps .
Your choice, but I enjoy the flexibility and freedom of root to take control over how my phone runs .
