Hi everyone, I just want to share some findings about two of my galaxy s3 i9300 international version.
I live in Malaysia and have been having the battery draining issue since day one. (During idle with both of my phones).
I've Installed betterbatterystats from xda and found out that the fast dormancy was the culprit.
I've tried various methods such as the:
1. turnoff phone, pull off battery, put back and charge to max then only turn it back on (keep it plugged in until you see the homescreen)
2. disabling fast dormancy through root app method. (AFAIK, Telco in Malaysia supports FD)
3. went into service mode (*#197328640#) and change it to 3G only instead of hsdpa and hsupa.
4. changed wifi settings to never.
5. disabled google now with all the location services and unchecked all three location settings under the settings.
6. disabled all unwanted samsung apps.
7. disabled all sync
Even with all these methods, the drain still there. Android System <20%
So, after some time of reading and dealing with how fast dormancy works in my country (Malaysia) Carrier (Maxis and Umobile specifically), through the utms service mode (*#0011#), I can see that the UMTS RCC stats is switching rapidly between idle to dch or pach.
Moreover, betterbatterystats app shows high usage of multipdp, secril_fd-interface when idle. (Clearly the fast dormancy is not working here).
Done some researches and found out that enabling the data roaming under the settings sorts out all the above issues and the battery usage for android system drops back to <10%, fast dormancy is actually working now (UMTS RCC stats will turn to idle when not in use) and multipdp is no longer showing in kernal wakelocks under betterbatterystats app.
Hope this helps you all.
Added on 3/12/12 - Do remember to do a full shutdown recharge first (refer to method 1 above) before you try to enable the data roaming.
Tested system stock firmwares
4.1.1 I9300XXDLJ1 CSC I9300OLBDLJ1 XME - Malaysia
4.1.1 I9300XXDLJ4 CSC I9300OXADLJ4 BTU - UK
I will test this on ELK4 built and see how it goes.

Strange that should make a difference but I'll try anything that simple if it will increase battery performance!
Will report back what my expedience is!

why not use fastdormancy toggle from play store?
I've tried the fast dormancy toggle but that is not a permanent fix as my country carrier do support FD. Anyway, for those who live in Malaysia, please try to do the full charge first (switch off, pull out battery for 1minute, put it back and charge without switching on. When its fully charged, turn it back on while its still plugged in) then you may try enabling the data roaming and finally unplug the cable and see the difference.
I've left my phone idling for 12 hours with wifi on and mobile data on and here's the results.

Hi
I'm using stock firmware I9505XXUBMF8 and when phone is idle I have high CPU load in range 10 - 40%. I tested it using CPU-Z.
Most using systemui. On pure Android or cm10.1 it also exists?

put watchdog on from the play store, then go into the setting and set it to monitor system processes and then wait for the alarm to go off, i think it set to 40% cpu usage, then you should find out what is causing your cpu usage problem, also it will give you a list of your apps and system process cpu usage.
Also make sure wifi, gps, bluetooth and nfc are turned off.

I have the same problem. And once i saw 2 cores at 1510 and CPU load was 10%.
I have installed the above mentioned app. And the result is Android media process. It is using more than 50 %
lots of hits if you google "Android media process high cpu"
here`s one, though not the S4, but still android.

I see this on mf8 every boot. It usually takes 10 to 15pc battery overall too. Annoying if i want to swap sim or battery

On my tablet i havent similar problem. I think its stoxck samsung problem. Could someone put screenshots from i9505 but not stock firmware
Sent from my Nexus 7 using Tapatalk 4 Beta
It`s nothing to worry about, my HTC One M7 has the same cpu, and cpu-z shows the cpu usage at idle as being anywhere between 5-25% mostly around 10% with one spike of 100% , but two core were asleep all the time.
But the phone is not really idle it has a lot to do in the with background processes, as long as when you put the phone to sleep it stays asleep and does not keep waking up and using battery power, i use the free "wakelock detector" to monitor this, and disable or remove any apps that keep waking the phone up.
John.
Has anyone got more of a handle on this issue. I've now upgraded to XXUBMGA on the I9505 and still get this issue - happens every build
The android media process really does take excessive CPU on a boot - making a swap of a battery or SIM an "expensive" (power-wise) thing to do.
It also with GE Android 4.2.2. There CPU running with 1134 MHz and CPU load like stock.
Hey all,
So im a recent buyer of the S5, got it 3 days ago and last night my phone was at 32% and i woke up with it at 2% thats a 30% i know this is not normal at all how do i find out whats eating my battery or do you guys have any idea what it could be?

You do have wifi on and I'm assuming data is enabled behind that. 30% drop in 7-9 hours(however long you slept) isn't that bad considering this is still stock experience?

phone radio is the calls which y done etc..the data turns off by sliding down the top bar..
and check on settings, and check only for gsm..(gsm=2g)

Phone radio is exactly what it, and the icon in front of it that is identical to the signal bars icon, say: The phone's signal receiver. The one that connects you to the network.
You turn data off by switching off the Mobile Data (and WiFi if you want to turn off WiFi) toggles in the notification bar....
Is this your very first smartphone, by any chance?
there is nothing in setting showing 2G, the only thing i found to turn off data was in Settings - Data Usage -Mobile Data and i checked it off.

it has not 2g but gsm dude..i just explained you that gsm=2g
Go to settings, more networks, mobile networks, then network mode, choose gsm.. Make sure you turn it back on or your data speeds will be slow as hell.. Personally I would just charge it overnight and not bother.

Hello folks,
I've had the Rogers Galaxy S 5 for about a week now, and since day 1 I have noticed excessive battery drain by "Android System". This source of drainage occurs especially during idle periods of time causing me to experience rather poor battery performance.
This here is a sample of what my battery stats look like at any given time, notice "Android System" is virtually always the number 1 source of battery consumption.

I executed a factory reset on the second day of ownership to examine whether this drain would be solved. It wasn't.
I went to bed, and woke up in the morning to check Gsam Battery monitor which gave me this chart:
Notice the part I highlighted in red which demonstrates the overnight battery usage!
Also, GSAM battery monitor still displays "Android System" as the source of the drain.
Among my colleagues I am the only one experiencing this phenomenon, and I am going to factory reset for the third time right now.
Going to run the stock firmware to see whether I am still experiencing this.
I will report back with any new findings soon, hold on tight to your seats!

I suggest you do the following,
-Disable Location in the notification drop down
-Turn off Hot Word detection for Google Voice Commands.
-Disable bloatware
-Turn off always active WiFi in advanced WiFi settings.

AND,
Try giving it a week to 'settle' without resetting it...
It needs to figure itself out...
All my family member noticed significantly better battery AFTER 1st week.

Certainly performed all of the above right after factory reset! Battery still dropped over 10% overnight on standby.

hi guys,
im troubleshooting my battery problem on this phone. just need some thoughts.
the drain is over 2%/hr when the phone is in sleep with flight mode on and nfc on.

the day before i tried this with the network on nfc on, data and wifi off and the consumption was about the same.
i have yet to try flight mode on and nfc off, but i wouldn't think that nfc would use that much.
i use greenify to put a lot of apps to hibernate so they wont wake the phone.
starting to think my battery isnt performing right anymore.

17% in 6.5hrs, airplane mode, no nfc.
the phone is definitely going to sleep.
i could leave the network on and nfc too, difference isnt big at all.
any idea is appreciated. leaning towards bad battery here..
Sent from my GT-I9500 using Tapatalk 2
Why not remove all the extra apps, and see if anything changes. Then, you can install one by one when things are clearer.
i would believe if an app cause the drain with the screen off then it is probably causing a wake lock.
which doesnt show at all. is there any otherway an app can drain the battery without wakelock?
Sent from my GT-I9500 using Tapatalk 2
I don't really see drain? 2% an hour is not that much. In my opinion it's normal.
If you insist on lowering it, then try the following:
- Different rom
- Different modem
- New battery
And search for some guides to lower your battery usage.
You have to experiment yourself.
it didnt use that much before. in 15 hrs i got a bit over an hour screen time before it hit 0.
anyway, just loaded romswitcher, going to see if it happens with CM too. and airplane mode on.
starting to think the battery is going bad already

I average about 0.5% drain during sleep.
See the link in my signature to find out how. I've got a whole guide.
Have you checked the serial number on your battery? If it starts with BD then it's stuffed Samsung should still swap it for free I think.
thanks for all the replies guys.
yes 0.5 drain should be normal when it sleeps.
just tried this using CM rom and it looks all good there, so its not the battery.
going to remove some experimental settings in greenify to see if that helps.

I purchased my 6P roughly 2 weeks ago and I'm not seeing this amazing battery life of everyone else's.. The best I've gotten was 4hrs screen on time with 25% battery remaining. I've tried tons of ROM and kernel combinations, as well as being on stock with locked bootloader, the battery life seems worse with kernels, and the same with stock based Roms. Below is my current SOT with stock rooted, stock kernel. Is there something wrong with my battery? Considering calling huawei for a new battery? This is pretty **** battery. My galaxy S5 had better. I constantly check my CPU States, it does deep sleep perfectly fine. No abnormal wakelocks, I don't even have Facebook installed. The 4 hr SOT I did achieve was with greenify and amplify, which I don't think I need for a phone with this kind of battery...

Depends on a few things. Could be a rogue app, wifi wakelock, or really poor signal.
You could try stock and no apps for a day and see how it performs then.

the apps i use are twitter, whatsapp, tapatalk, slide for reddit, snapchat, instagram, open camera, and neko atsume. thats pretty much it. Of course cpu spy for monitoring, and sometimes i do notice wifi taking up a bit of battery, but even if i disable it and it goes away, the battery life is still poor. I have a moto 360 and I usually have it paired via bluetooth. I also use google now but i set the GPS mode to either device only or battery saving mode. reverting to bone stock google images locked bootloader to see if it makes a difference, again.. even if the wifi isnt draining.. still is poor. I did monitor my signal and i get very good LTE signal all over my city, so I can rule that out. Would huawei honour this request? I am located in Canada if it matters. Also i dont think its app related because i use the same apps on my S5 and the battery is better on it, which doesnt make sense.
Have you tried turning off WiFi scanning and Bluetooth scanning? They're pretty much useless but consumes battery.
Go to Settings > Location > Menu > Scanning > toggle both settings off

So I have had my phone on for two days now and charged back to 100 of course. Total screen on time over that period is 3 hrs.. This is brutal. Phones at 58% right now. I'm noticing this (screen shot) is this the culprit and does huawei do warranty in Canada?
