Galaxy s4 battery problems

[OneMoar]

The battery already sucked with the stock ROM, and there appeared to be a slight improvement with Cyanogen, probably due to less junk running in the background.

what s4 on what carrier are we talking about
if its a i950/5/6 with a unlocked bootloader i believe there is linage os builds

SPH-L720 on Freedompop (Sprint MVNO)

Bootloader is unlocked, at least unlocked enough to flash Cyanogen through Odin... or maybe I flashed TWRP through Odin and Cyanogen through TWRP once it was installed. Was a bit of a while ago when I did that so I don't remember exactly the specific details.

Cool, I'll try installing that tomorrow. Running android 7.1 instead of 4.4.4 would be interesting. I actually downgraded from 5.1 or 5.2 when I flashed this cyanogen ROM.

 

[OneMoar]

running 4.x is likely part of your problem the kernel is trash
do note that jumping from 4x to 7.x WILL require a full wipe including a full delete of all partitions except for EFS/modem

edit: make sure you update twrp before you flash anything

Must have been trash on 5.x too, the battery was even worse then.

Strange. I had the official Samsung 5.1 on my S4 for about 2 months. Not as bad I thought. A full charge can hold 2 days, that is constant emailing/msging and tracking of fitness data.

Who knows, maybe it shipped with a garbage battery. It was "refurbished" after all.

Well, that didn't work out too well. It won't connect to the Freedompop network with that ROM. I tried changing APN settings but it still didn't connect after that. I might be able to get it to work if I play with it more (open to suggestions) but no time now so I rolled back to my backup. Good thing I made one! Learned my lesson about that the hard way not too long ago. Seems like when you remember things better when you learn the hard way...

had the same problems with many samsungs over the years, you're getting fake/B grade/refurbed batteries.

Make sure to get a genuine one in the samsung retail box.

 

[OneMoar]

did you try flashing this after the rom
http://www.mediafire.com/file/mc1kipz9nugftbi/Freedompop+APNs+fix.zip

old but might do it
I know that rom works with freedom pop there are people in that thread using it

make sure you don't wipe the modem/efs directorys

I am sure its just a APN problem it usually is

this in the apn's from that .zip

edit: freedom pop apparently requires multiple entries to work (bah stupid 2d tier carriers)

flash the zip after rom and gapps

make a backup of the 7.x rom that way you can fiddle with it without loosing service

would probly be of help as well

happy flashing

Just my few cents from warehouse...

Is it genuine though?

Fake batteries are big business and there are only a few brands that make good replacements that are trustworthy

I don't do stuff with fake knock off parts. This is sourced directly from Samsung. An OEM part.

 

[Ahhzz]

I'd be tickled to move higher than the 4. OS that I'm running, if I could get a stupid root to take :/

 

[brandonwh64]

Rom's that are not poorly built can cause these issues. My old LG G3 would have crazy battery issues with Cyanogenmod roms but other would be good after a battery calibration.

@OneMoar already tried that APN fix .zip, didn't work. I'm sure it has in the past... but not now, for some reason. Not really interested in dual booting... but thanks for the option.

It's my big weekend (3 days) so I have time to muck with it. I'll see if I can come up with something.

Well, I got that ROM working. What I did was copy down my APN settings from my previous working 4.4.4 rom and entered them manually once I flashed the new ROM. Seems to work okay...

The ROM seems to work well, so far. I opened the STweaks app and selected the extreme battery governor profile, so maybe that, combined with the updated version of Android (and a slimmed down, tweaked ROM) will help.

 

[OneMoar]

do everybody a flavor and post what you did in rom thread so people can repeat

also the kernel/rom should support doze which will go aways

zzmove is good but it can have some stablity problems if you get Rr's thats where you should look

Not sure what any of this means... lol

I'll post in the thread later, though. Interestingly enough it looks like you posted the same data I entered manually... I wonder why it didn't stick when I flashed that .zip?

that zip is very old and probably very broken on anything above android 5.0

could be anything from a permissions issue or a formatting change in xml parasing

I am ever bothered enough maby ill update it I don't use freedom pop but i have been considering it as a second line

zzmove is one of the governors in the alucard kernel you said you switched to extreme battery saving that usually means zzmove

I dunno. I seem to remember the zip working in the past but you could be right, that was certainly with an older version of Android. This is the first time I've had a current version of Android since I got my Nexus 4 back in 2013 I think, when Jelly Bean or KitKat was current. I'm liking the ROM so far... as a PC enthusiast who likes to tweak things I love finding ways to tweak other things and make them better. Giving an older (but still capable IMO) phone new life with a custom ROM not only updated to the current version of Android but also with all the junk cut out of it is nice.

A bit off topic but since you said you're considering FP as a second line, I'll share with you my experience as a customer. This is all based on their free plan, so keep that in mind. It's 500MB data, 200 minutes talk time and 500 texts. You can get around the talk time and text limit by using another app like TextNow (though it has ads if you don't subscribe to them, and AdAway doesn't remove them). Once you reach 400MB data usage, you're cut off, in order to prevent you from going over the 500MB limit (so they say) so you should really only consider it 400MB. At this point you can buy more, of course, but then it wouldn't be free... anyway, the actual cell service, at least in my area, is honestly pretty lousy. They run off the Sprint network, so that's what you'll get... and since FP runs off VOIP, call quality is directly dependent on how strong your signal is. Calls work okay with decent wifi of course but if you're depending on a less than stellar cellular connection, forget it. In a nutshell try not to depend on it for anything important if you can help it.

No doubt you have a faulty battery. It reports as 40%, but it's really zero. Time for a replacement.

This doesn't sound software related at all.
