Hello! I've got a S4 mini black edition (GT-I9195 with stock 4.4.2) and as many other users I also noticed the battery drainage problems (standby uses too much battery). Is there no way of solving the battery consumption problem without rooting/flashing custom rom? (I don't care much for breaking knox as long as the problem gets fixed). I've read several threads about this issue, but still i need some advice on what's the best solution available these days.
Thanks!
You can try any custom kernel like on below ::
http://forum.xda-developers.com/showthread.php?t=2592308 Thanks to @SilviuMik
or this :: http://forum.xda-developers.com/galaxy-s4-mini/development/kernel-brisk-v1-drain-patches-t2852609 thanks to @TheBootloader
Or you can try any stock based custom ROMs. Check out the " android dev " section.
Without root I am not entirely sure how we can improve battery as main problem is with stock kernel.
Thank you sasank360! I did read the brisK thread before maybe I should it. What do you think its best, those custom stock roms or a cyanogen mod? I'm looking to solve that particular problem only.
Cyanogenmod 12 is great ROM. But for me the battery life is lower that other ROMs I tried. In daily use of about 14 hours I get over 2 and half hours of screen on time with cm12
All lollipop ROMs give me same result. But stock based roms give me atleast 3 hours of screen-on time and I will still have 10% left @ end of the day. All custom kernels for stock based roms are same for me. For CM12 or any lollipop roms you can use @F4k kernel. It offers underclocking and undervolting options.
http://forum.xda-developers.com/showthread.php?t=2568479 This is link for f4k kernel.
I now belong to the "Knox 0x1 club", rooted and running CWM+brisK kernel, hope this solves the problem!
Hello,
My GF's S4 Mini is 2 years old, not a single hard reset, with unrooted stock ROM.
She is happy with performance and with phone in general but battery is bust, it barely holds for 10 hours with light to medium use.
She uses her phone for WhatsApp, Messenger and occasionally taking some photos.
I am not sure though which version does she have. I can find out that later today but meanwhile I would be grateful for your advice.
It doesn't have to be the newest ROM version, it has to be reliable, with good battery and preferably with stock camera app.
Thank you!
There is no perfect rom. Keep the rom she is using. Change the battery , after 2 years is busted as u said
It could also be old problem that battery was draining fast even with 3g/wifi/gps OFF. That`s a motherboard problem that can be fixed by changing motherboard or with a custom kernel that have the fix implemented. Stupid thing is, after u install a custom kernel, u need to root phone and disable Knox apps or they will bother u. Search what version of S4 mini she have, what rom she have and start from there to search. I have for example some kernels with fixes for that problem, but first read on forums.
The above being said and valid...
... I find that this ROM: Resurrection-Remix-LP-v5.5.8-20151026-serranodsdd
works pretty well for me. It is stable enough. You would have to root and stuff but its worth a try.

+1. RR LP 5.5.8 is very stable and battery friendly and also Blisspop 4.0.3 last two versions are good enough. BUT, in these 2 fantastic roms i have found a major bug (at least for me) that during incoming calls most of the times my contacts dont show up their names (only numbers) or sometimes very lately. I asked the devs about the problem but did not get any reply. So m back now to PAC rom KK 4.4.4, i used it for around 4 months continuously before i tried lollipop roms. Stable, good battery(05/01/2015 version) and hell lot of features.
N.B: The above is based on my experience only. It may very from person to person. And also it does not imply that other roms are worse or better, because i have not tried all of them.
What I have observed is temperature and the kernel have big impacts on battery drain. Stock 4.4. drains the battery much slower than 4.2., and the Cyanogenmod kernels also use up less juice than the stock roms.
the same
I have same issue. 2 or more years i9195 with stock 4.4.2 android. Battery drain is about 1%/hour at idle (sleep). When using it raises to 2-5%/hour. I want any other ROM or kernel that drains less battery. Please help
My phone has almost two years. Battery remains excellent. No tricks, such as calibration, etc.
In my experience the best ROM Stock based is this http://forum.xda-developers.com/gal...t/gt-i9192-galaxy-s4-mini-duos-4-4-2-t2832673 .
I never installed another kernel, etc. in its use. I tried several ROMS CM based but always came back to this rom for stability, reliability, battery.
But lately I have been interested in Android M.
And I was already giving up again when I decided to use CM13 (feb / 21) by K2wl without GAPPS (Open GAPPS) or Custom Kernel.
My intention is to test CM13 in its purest possible code.
So far it has been amazing. No call issues, great battery (as in SilviuMik ROM). etc
I'm curious. Will this time be able to use a ROM CM based for more than two weeks without problems with Call and battery? If this happens it will be worth testing other GAPPS.

ADR USR, your suggested ROM Stock is for i9192. Will it work with i9195?

I do not think so. But this is not a problem. Just try the kernel to 95:
http://forum.xda-developers.com/showthread.php?t=2592308
I believe that all you need. I never got to use debloated version of this ROM. I'd rather do it manually.

I used the official CM12.1 nightlies (& kernal) for about a year on my I9195, in the first few months I did get almost weekly random restarts, as you might expect on a nightly, but towards year end almost none. Then I installed the last Snapshot YOG9 (or whatever) and didn't get a single reboot in months.
http://forum.xda-developers.com/gal...i9190-i9195-cyanogenmod-12-1-s4-mini-t3100159
Currently I'm on an unofficial version of same CM12.1 that has latest monthly security updates patched (which will be built until a stable release of CM13 is out) as the official CM12.1 development has stopped due to CM13. I've not had a single crash or reboot on this CM12.1 ROM, so that's about 6mths with no problems all together.
http://forum.xda-developers.com/gal...i9190-i9195-cyanogenmod-12-1-nightly-t3300836
My wife is on CM12.1 (NightOwl) too on her old Note N7000, she has not had a single problem in the 2mths since I installed it. So long story short I'd say almost any version of CM12.1 is now very stable (provided you clear caches etc when installing and don't load dodgy apps )
CM13 version not suggested yet?
The best choice is the updated CM12.1?

I have been using cm13 nightlies ever since it came out. Almost updated every new package. Since then i had to revert it twice. For me so far it's stable. Using it with gapps pico. But do nog use any extended cm13 roms like bliss or rr, as they are highly unstable, lagy and full of buggs.
Have a nice day to all. I have an i9192 (GT-I9192ZKAAFR, S4 mini DUOS) with the latest original I9192XXUBNB1 ROM and the CSC is I9192OJVBNB1 (AFR / Kenya / AE). I have to use this phone again and it is horrible. Often becomes hot and unresponsive. Sometimes just simply shutdown itself or reboot. That is why I moved to another phone but that is in service now. Otherwise this is an amazing little device. I decided that it is time to take steps towards to a more stable ROM. Phone has Knox and it is still 0x0. Manufactured in 2013 and bought in 2014 so support has definitely gone. Therefore I am not really keen on Knox status but would be great to keep 0x0.
I am a Hungarian user and I would like to use Hungarian language on the phone. I see some ROM recommendation here. Is that true for Hungarian language as well? What about different region, modem or so? Are these ROMs working on my device? Is it possible to revert my phone to any factory version? I am not familiar with flashing ROM on this phone but read some tutorials and more or less trained.
Hi,
I'm on Exodus (+ Gapps pico) & very happy by the quality of this rom. (I haven't tried many other roms though)
I've flashed a lot of Roms but can't seem to find one giving good battery life. Yes, my battery is fine I checked. Any recommendations on which ROM to use guys? Phone is rooted right now on RR ROM and I know what greenify is with Xposed features.
(KitKat to the test cm14.1)-pick a ROM
Cyanogenmod 13. Not perfect, but the best you can IMO.
Hi I am facing a problem in my z2 plus which I purchased this January, I root the phone in march and then installed custom ROMs on a daily basis, I liked to try out the different ROMs available for my set, then I noticed that the battery life of my phone was decreasing, I thought it was because of a single custom ROM but no custom ROM gave me the perfect battery life, so if I install stock ROM will my battery performance be like it was ?

Try Qfil if battery backup is hindered because of some rom stuff then it will be resolved else it's hardware issue.
