Hi,
New to playing around with custom firmware on my Galaxy 5 player (yp-g70 US)
I have tried the pacman version and slimbean so far.
They all look much better than the default gingerbread stock rom configuration.
I would love to use one of the custom firmwares but have reverted back to Gingerbread because I have found on any of the custom built firmwares I find here that the battery life is less running custom firmware. This is wth ALL settings that could use battery power turned off, no wireless tried airplane mode etc.. (Disabled all services) I have found from GSAM batter monitor that there is a type of service listed as Phone Radio and under any custom firmware I have tried here it always lists as using most of the power if my player just sits in a deep sleep state. (after 48 hours idle 98% of the CPU use says Phone Radio)
This Phone Radio is NOT present in Gingerbread at least its not even on the list of apps consuming battery power, I even found some type of zip install that I used clockwork mod to run that supposedly gets rid of the phone radio from android/data or something like that. (And I recall verifying this was gone in the file manager)
Is there any way to really kill off this Phone Radio thing? Why is it even present in the custom firmware for the 5.0 Player?
Normally in Gingerbread if I let the player sit in deep sleep mode only like 1% will drop over 24 hours. With custom firmware it seems to be like 5+ percent.
Thanks to any one who can point me in the right direction. I searched this forum first for any threads with Phone Radio in them with no results.
Thanks

The phone radio is a false positive: there's no radio in the device, so there's nothing to worry about. Battery life will decrease on any custom firmware, particularly if you're jumping from Gingerbread to ICS or JB. Personally, I've found running CM 10.2 builds on my 5.0, that I'm able to get around 2 days of light usage (I turn it off at night).

Ahh, ok. I was hoping there was something to that.. Yeah I figured there was something to it.
I was also going to try comparing Slimbean with none of the extra Google apps installed and freezing / disabling as many services as I can to see if I can make it close to Gingerbread..

I don't think freezing services will help much. The battery drain that you're seeing is more a result of the way the 4.x code runs, not so much the services and software. For the 4.x improvements, you're gonna have to give a little to get a little. Unfortunately, it seems that we can't have our cake and eat it too!

Yep you are correct. I spent awhile disabling everything that was not essential for my use. Made no difference with the extra drain. Was going to experiment with kernels, but I suppose it is just a small trade off I will live with.

Hi guys sorry for this thread new here so please go easy on me. Had a galaxy s2 for a few weeks now and i have to say best phone ever. Did the normal rooting and flashing roms and i have noticed recently that my battery has been going down quite a lot after a few hours. I tried roms like Villainrom, Cognition, Batista and etc which i find them very good but on my battery stats it says that i have high display usage and the percentage is like 56 - 85 and sometimes goes and stays to 91. i have since then when back to 2.3.3 stock firmware rooted it as well and i only have display percentage of only 25% which i think is normal and my battery lasts longer. I have spoken to Samsung regarding this situation and they are sending me a new battery but im just wondering why i cant flash a custom rom without having to worry about the high display % and what can i do to fix it? do i have to give it a few days for the battery to settle on the rom or shall i just stay with the stock rom for now till i get my new battery and then try to flash? sorry for the long essay i just need to find out if any one else had the same problem as i really like to use a custom rom that my normal one.
THanks
I too find it very hard on the battery with all the custom roms that I have tried out. I tried, Villain, Cogniton, LeoMar, Batista, etc..etc..etc. I have in fact tried out all the ROMs out here. Tried even different combinations of Kernel, but all only lead to the frustration when it comes to battery life. I finally tried MIUI ROM and I can say that it is giving me very good battery life compared to other ROMs.
It is interesting to note from you that the STOCK ROM has given you better battery life. Could you please tell me how long did your battery last in Stock ROM and what are the Apps that were running in it?
Install Better Battery Stats, I don't think anything wrong with the battery.
See under Wakelocks what apps/processes are going in background and causing the drain. Then take necessary steps with TB Pro.

to xdadeveloporian: thanks for your reply bk and sorry to hear that you had the same issues. like i said above i am very new to all this so apologies if i am replying with noobish comments. with wifi on and the normal widgets i had a battery life over a day. only charged it once and it still going. is that rom that you using now good?
and to ithappy sorry what do you mean by your reply i do not understand sorry. and do you guys think with a new battery it will fix my problems and i will be able to flash roms or do i have a faulty phone?
% is not important, what really matters is total time on for the display. Are you sure it isn't that the stock ROM burns more power in other areas, so the display is less? Or maybe the brightness is different? I'm not even sure how the display proportion of battery drain is apportioned - is there really a current sense integrator?
now that i have the stock rom with firmware 2.3.3 display is 30% followed by android os 15 - 19% which i think is normal into regards were i was on customs roms and the os was 15% and display 50% and over. brightness is basically at the lowest i can put it i am using touchwiz launcher and i only have two pages with widgets and nothing else. just a bit confusing thats all. i mean with custom roms the battery should be alot better not the other way round if you get me.
apologies if im not making any sense here. thanks again for all your replies it does help

I don't believe that stuff, why battery life would be better in a Custom ROM, because they added/modified some stuffs, nah. You can make a Stock ROM custom with some little modifications if you are rooted and have great apps like Root Explorer, Titanium Backup etc. I, for me, will never ever use a Custom ROM. But that's just me, don't take it any personally.
And about battery, don't see that how long are you getting with it, like- 1 day, 2 days, they don't make any sense, just keep an eye on the 'Screen On' time, if that is around or above 5 hours then you are very fine. And also keep checking that your Awake and Screen On bar is synchronized or not, if it is not then you must have something going on background, like- Latitude, Email exchange etc. which you can see under Better Battery Stats. And also, when not needed turn off, 3G, Packet Data, WiFi, Auto Sync, Background Sync and check how many apps are on Auto Sync, if not needed then modify it to Manual Sync.
Regards.

Maybe they fixed some bugs - specifically a custom kernel might have improvements or bug fixes (since there is lots of work going on here from many companies making contributions). This takes time to filter through to the official ROMs.
Maybe they removed some of the stock apps which contribute (maybe only slightly) to power drain.
Maybe the small differences in the ROM mean that existing bugs are less likely to have an impact, so even not fixing the bug it seems to have gone away.
Custom ROMs are as likely to make things worse - but if many people are affected then it is likely that someone will track down the reason.
Look all i know is that as soon as i started flashing custom roms on my phone my battery life has been going down like hell. Checking battery stats the most thing that is taking up battery life is the display being as high as 80 even 90 percent. I am not a expert on android having had an iphone all my life so when people say underclocking and other stuff its like new things to me so i do apologise for being such a noob. i do love my galaxy and i think its the best phone out there at the moment. all i need to know is if there is something that i can do to bring the display down and not to have it drain so much out of the battery..
Thanks again for everyone for replying
very niceeeeeeeeeeeeeeeeee
huh? has anyone else experience high display usage on their phones when checking battery stats?
is that from the android market i can get that app?

I have the same phone. I'm using stocklite v2 very happy with it. Installed an ICS theme and did some additional customizing using UOT Kitchen (google it). Works like a charm.
Don't forget to make a backup before installling any roms.
success
Using The End 3.0. Tried Stocklite (both vsns) but battery life didn't noticeably improve. Tweaked my settings on TheEnd and it's comparable to those ROMs now. Not sure how my phone model changed to the regular GT-S5830 though. No more "D" now. I guess that has something to do with the kernel changing?
When I got my SGS3, I could have it on for about 2 days (with minimal use and bluetooth and gps off and such), but ever since I updated to 4.1.2 (from ICS to JB), it looks like the battery drains a lot faster. So I got Titanium Backup and removed most of Samsung's' bloatware, disabled Google now and finally got BetterBatteryStats to pinpoint the source. I found some minor things and disabled them too... I've optimized all settings across the board, yet I still can't get much longer than one day.
Now I get that one day is nice, and most people charge every day, but when you're used to having 2 days (or at least 1.5 on normal use), 1 day is just.. less
So, I am kind of hoping that someone with more knowledge than me (basically everyone here ) would have a look at my BBS dump file, because I'm kind of at a loss.
It would be much appreciated!

Do you mean "Location determined by wi-fi and/or mobile networks"? Isn't that used (among other things) to find the GPS sattelites way faster (because if it knows where you are, it knows where the sattelites are)? Because I use my phone for car navigation, I really would prefer not to wait 5 minutes while my phone searches the sky for GPS...
I'll turn the option off for now, but do you really think that's the main problem? Because I had the option on before this update.
Still, thank you for your suggestion
Location by wifi is unrelated to GPS location, it's just a way of roughly fixing your location by the networks and wifi around you.
It's a battery hog and doesn't matter AGPS, which is used to speed up GPS fixes but gets downloaded via your data connection.
I found JB to be better for battery life that ICS, even on a stock ROM. Since changing to a minimumcustom ROM based on the latest stock I get two days use with around 6hr screen on time.
If you are still on stock that was updated from ICS then you might be better off wiping the phone and flashing a fresh install, even if you only use the stock JB ROM for your country, as things might have become corrupted over time.

I think your issue is fast dormancy as you have the secril_fd wakelock.
There is an app on playstore that can toggle fast dormancy on or off on the Galaxy S3.
Give it a try and see if things improve.

Ok, I've installed it and turned FD off... I'll do a full charge now and see how long that keeps. Thanks for your suggestion! Is FD a new feature since JB? Because I haven't changed providers so if this has always been the case, it's probably still a seperate problem.
To be completely sure, I'd still like to do the complete reinstall, so I would really appreciate it if someone would point me in the direction of official updated stock roms. Thanks!

You can reset it completely through Kies if you go to Tools>Firmware Upgrade and Installation and follow the instructions this will flash the latest firmware and reset your phone, do any backups you need first like contacts etc, then root the phone again or do whatever you want afterwards.
FD is not new. It just depends whether you provider supports it or not. If it is not supported and switched on it can cause battery drain.
Saying that my network does support it but when I first upgraded to XELLA I started getting the secril_fd wakelock. Switching off FD solved it at the time. Since then I have made a few changes, including modem and have switched it back on again without issue.
I noticed you've also got the Multipdp wakelock. A modem change sorted that one for me.
As I say I've since moved back to XELLA without issue and neither wakelock has returned.

Ok, thanks for the info. I don't think that's my problem though: my provider hasn't changed, the only thing that changed is that I upgraded to JB. Either way, I tested it: with FD off I still have pretty much the same result (maybe a bit better, but I need to properly test that. Yet it's definitely not the problem ). Too bad, it was a good suggestion.

Thank you! I just did this. I expected that all my settings would be gone, but apparently that's not the case. All my apps remain, so I wonder if this wiped it properly? I did lose root though. Well, I'll charge it to 100% and we'll see what happens from there. Thanks!

overnight it lost 25% in 11h42m, so I'd say that's a definite improvement. It didn't see any use in this time, but it should last me at least 1.5 day now, so I guess the problem was in the update after all. The battery of my (6 months newer) SGS3 still holds out longer, but I think that's the battery itself: hers also charges faster than mine.
Thank you all, for helping to think up solutions and get it working for me again! :victory:
Edit: Multipdp is now a lot higer up in the list (it's the top partial wakelock), maybe I should change modems. Can someone tell me how?

Hello,
I'm running 2.3.6 now and I wonder if I switch to 2.3.4 will I have less battery drain? Are there any functional lacks on 2.3.4 comparing to 2.3.6? However, I use GO Launcher on rooted phone.

Well next time please do post questiona in the general sub forum Anyway I think it is better to just update to 4.1.2 since you are rooted anyway. I get better battery life and signal on 4.1.2 compared to 2.3. My choice of a rooted stocked based rom would be NeatROM Lite by Sale :good:
I agree. Generally, upgrading rather than downgrading will increase performance so I would just go wit a higher version. Also, if you feel you have an unnatural battery drain, there are other options except switching versions to handle that. Maybe it is one of your apps that causes the battery drain. Other possibilites are sync cycles or kernel. If you switch to another kernel that might help your problems better than switching ROMs (although switching ROMs is always recommended, just for the fun of it )
gulypi which
I don't know if I am doing something wrong, but I just flashed NeatRom 5.0 and the battery life is terrible.
From my point of view, 2.3.4 stock with speedmod kernel was the best with my s2. I had battery life for 2 days. With latest roms I have battery life for max. 24h. I always did a clean install with factory reset. Don´t know why the battery life is so bad with my phone.
But now I ll give it another try. I will format the whole phone and try sentinel rom again which i liked most
NeatRom 5.0 killed my battery also. Trying 4.9 for now as I jumped from 4.6. If it's buggy I will switch back to 4.6

Media scanner fix for battery problem on neat ROM should fix this. Also Apollo kernel is great mix with any stick Sammy ROM.
I don't know why flash modded kernels (at least if you are about to have better battery life, not other mods)? I have plain stock GB 2.3.6 XWKL1 (DDKL1) and just use Go Power Master, Set Cpu and calibrated battery.
At first when I went back from ICS to GB battery lasted for 14hrs. I charged battery fully on and battery "learned" new system and went up to 23hrs. Then I calibrated battery: fully discharge till phone went off, again started, playing till off again and again till it won't on. Then without turning it on I charged battery fully, unplugged charger, waited till battery went to 99% and plug in charger again till 100%, and again. I was using WiFi over half time of usage, flight mode at nights, play wit phone settings, installing apps, browse internet a little, use as phone as usual, listen a music a little, browse photos, etc, and battery lasted for 39hrs on stock battery which previous owner using for last two years and he didn't care about healthy battery usage. I got Samsung Extension Pack with 2000mAh Battery and flat back panel but it waits for new S2 I bought yesterday. I will put new battery after ROM flash and get all restored to state I have now, then I calibrate that bigger battery for new phone.
But anyway, question was if someone was playing with 2.3.4 and 2.3.6 stock ROM's in order to achieve better battery performance? I read somewhere that guy had over 4 days on stock battery and 2.3.4 GB. So I wonder if I switch to 2.3.4, which may be probably less demanding system than 2.3.6, will I get more time on one charging? I don't care about how it may or not look like cause I use GO Launcher anyways, but does it have same stuff and functionality as 2.3.6?
The problem with comparing your phones battery life is that it's depending on too many variables. You can't just say 'My phone lasted 30 hours with this and that usage', because everybody is using it differently. If you really want to test it, flash both versions yourself and try.

In addition to Donnie's very good point, you're asking about 2yr+ old firmware. Do you realise how few people on a site like this are actually running firmware that old ? You'd probably find a fair number of 'ordinary phone users' out there who are still running GB because they may not be technologically au fait enough to do an OTA update.
At the end of the day, changing firmware to squeeze every last drop of battery life becomes a game of diminishing returns in that you can spend a lot of time to get that last tenth of a % of use out of every charge. You have to ask yourself is it really worth it, or is it worth simply enjoying your phone & chucking it on charge every night (or if you really chew through battery, getting a spare).

Well, the thing is I don't understand why people update their phones and then complain about battery life if 2.3.6 works fine from what I observe here and there.?
As per Donnie's post, there's too many variables involved to say 'This Android version will definitely give you better battery life than that version'. Personally, I get better battery life out of JB roms than I ever did out of GB or ICS roms, not that I got poor battery life out of either of those though. And the reason for that is I worked at it.
There's no magic simple A-B-C to better battery life, regardless of what rom/kernel/Android version you're running, you have to experiment & try stuff out to find out what works with the way you use the phone/have it setup.
People who complain about battery life & attempt to pin it on the particular Android version they're running tend to have a really poor understanding of 'how it all works', because it isn't that simple as I've said.

People can also update their phones because of other reasons than battery life. ICS was the best for me with battery usage, but after JB downgrading isn't an option for me as I would miss to many new features and other additional functions.
The choice is yours to make. If you are satisfied now, I would stick to 2.3.6 if I where you. If you are curious about other versions -newer or older- try those
I installed cm11 on my s2 a while ago using the installer and since then im trying to figure out the reason for the huge battery drain. Cm works great but it drains the battery in an average rate of 19% per hour (a special app did the math,and i can clearly see for myself ). I dont do anything more than music, surfing and whatsapp. Android stats usually say the screen is the no1 battery drainer. Android os second.
I searched the internet and tried every possible tip there was. IMO the only thing I hadn't tried is flashing different modem and different kernel (didn't find good guides for it and was afraid to brick the device)
What I have tried:
1. Flashed neatrom just to compare. A little improvement but still not like old days and of its not a good performance like cm.
2. Went back to cm through recovery backup and Used battery stats, taking permissions away from every app with a redundant wake/cpu lock.
3. Got new battery, assuming the problem may have to do with an old battery (bought the device 2yrs ago)
4. Calibrated battery both with the app and also using the manual trick (chrage while phone off, take batter out, wait five mins and put back in).
5. Tried different governors.
Might be forgetting other things. Nothing works!
What can I do? I really wanna use cm and not get lost flashing less good roms.
Thanks
This device uses an old Exynos SoC optimized for Android 4.1, In new versions is normal battery performance loss because there is more consumption of resources
It also warms up and all.... You recommend flashing older version of cm?

Yes, only if you really need more battery life. I have a Galaxy S Advance, who died in the 4.1, Battery life in 4.4(CM) is 30% lower than the official 4.1.
