Thank you cause I've been looking everywhere for answers and seen people blame Roms for battery drain.

After first getting my phone I was told by someone to not let my phone die after charging and only do it once so I did so since then my battery has been terrible after trying custom Roms and updating

firmware.

So I let my phone die from 100% then charged it again to 100% and my battery was great, was going to send my phone back.
[Galaxy S III General] jgalvez21:
for me it wa s - memo and stock browser i freeze those too battery lasting me ages.
[Galaxy S III General] KennyLegend:
No prob. I've answered this several times over the last few months. You can't judge battery life after a few hours on any firmware. It needs a few full charge cycles from 100% to 1% and back to 100% before u can judge battery life/drain accurately.

Having said that... There does appear to be a drain problem associated with wifi on idle on the latest JB firmwares.

[Galaxy S III General] XenomorphXx121:
Think it has to do with the modem, they're still using the one from Germany and it hasn't been updated.

Maybe the signals from that modem aren't fully compatible

Or it could be something to do with automatically updating your location from this device option in google maps/report from this device
[Galaxy S III General] KennyLegend:
Kernel is responsible for wifi, not modem.

Looks like this WiFi issue its also linked to router.I have a Cisco linksys router. I don't have this battery drain issue on LJ4. Even on idle the drain is not more than 3 to 4 % overnight
[Galaxy S III General] XenomorphXx121:
I'm still learning :D

Is the Indian firmware a different kernel and has anyone tried it?
[Galaxy S III General] KennyLegend:
And what have u done on your end? Have u set up a static ip or...?

Does anyone know Is it 2.4ghz related?

Does changing to 5ghz band make any difference?

Sent from my I9300XXDLJ4
[Galaxy S III General] omeryounos:
No, it's dynamic ip. 2.4 ghz.
[Galaxy S III General] KennyLegend:
Ok thx. Might try logging into my Netgear router so instead of my modem to see if it makes any difference. Might be a more stable connection.

Im losing approx 20% overnight with wifi on. Alls good when i turn wifi off. Nothing is jumping out at me looking at BBS log.

Yeah I read this before. It's not good to drain completely but leaving battery go down to 1% is ok.

Is this a ROM or stock firmware? It looks pretty customized.

With stock I can't get this kind of battery life, doing the same things you did, especially with full brightness....
[Galaxy S III General] eggman89:
Same here. THe only wakeloks I get is from Android System.Yet the wifi drain is horrible.
[Galaxy S III General] jnr21:
No, it's not stock. Those screenshots is from omega v31 (based on xxdlj4).
[Galaxy S III General] pähkinä:
I had pretty bad drain when I had Google now turned on. So I turned it off and disabled every option in Google maps under the location options, and now it's back to the way it was on ics. Wakelocks are gone too.
[Galaxy S III General] POLO_i780:
Siyah kernel already showing positive results!

I just flashed the latest Siyah kernel and the phone overall is running faster and im seeing an improvement in power consumption, still, its early days, lets see how it goes over the next 2 weeks. :)

PS. Im on the UK DLJ4 FW.
[Galaxy S III General] dibyajyoti:
A lot of the battery drain comes from Google Now's wake up command similar to that of S voice in GT-I9300.. Disable that from Google Now's setting and you'll see significant difference in battery consumption.
[Galaxy S III General] KennyLegend:
And of course anyone who has read anything on here lately from a number of threads will know this.

I have google now disabled, location services off and maps frozen ;)

Turned off Google Now a while ago, the very day i updated to JB in fact, thanks though! :)
[Galaxy S III General] :
Have been having terrible battery in standby even with data and wifi off.. In 10 hours it lost 13% and that's with data and wifi off.. On ics i would get maybe 2% battery lost overnight with data and wifi off... In battery setting it shows android os being awake for over an hour but don't know what... Don't have a voice or Google now turned on..
[Galaxy S III General] A|ex:
Battery for me is fine, a friend of mine gets a week out of the S3 and i am around 3 - 4 days on JB. Its more or less the same as ICS so cannot complain. Once you have figured out the killers of the battery using betterbatterystats the rest is easy.
[Galaxy S III General] XenomorphXx121:
Leaving on power saving helps also with better network, less drain and don't really see any difference in performance.

Not sure if it's a bug though but switching off power saving gives less screen percentage but more drain and having it on gives more screen percentage in battery stats but less drain, shouldn't it be the other way around?

I probably have a faulty phone.
[Galaxy S III General] sfjuocekr:
If you use your phone, it won't last a day.

If you don't use it, it will last a day.

It's common smartphone philosophy, deal with it.
[Galaxy S III General] Matcarroll:
I've just noticed something. I have got into advanced settings in WiFi and setwifi to never stay on when asleep. Sometimes it seems to turn off and other times it stays on. It's very random but my phone uses about 4 times as much power in standby with WiFi on rather than WiFi off and keeps awake a lot more also. My best option at present is to turn WiFi off and on as I need it. This gives me excellent battery life but a little inconvenient.
[Galaxy S III General] KennyLegend:
Ok... Pretty happy with mine now. 70-67% in 7 hours overnight with wifi on. And it possibly could have been better if it wasn't for the 3m wakelocks by the "ebay" app.

So it seems that having a good router matters. Must be to do with keeping a stable connection and not having regular dropouts.

Sent from my I9300XXDLJ4
[Galaxy S III General] XenomorphXx121:
Maybe try switching it to static?

I have a brand new netgear wndr4500 router with excellent reception. It's the same on 2.4 and 5ghz channels and also the same at work where it's a poor reception. Will try with a static address over the next few days and see if it improves. Too many people this is happening too for it NOT to be a jelly bean problem though, some people seem affected more than others.
[Galaxy S III General] KennyLegend:
I have the older version of yours.. Wndr3700. ;)

Maybe a static ip will help your problem.

Have u tried a different kernel?

I'm using Siyah and I find it really good.

Sent from my I9300XXDLJ4
[Galaxy S III General] Matcarroll:
I don't want to get into flashing kernels. I'm stock unrooted at present. Just changed to static ip and battery gone down about 4% in 40 minutes or so so didn't resolve matter. Back to turning WiFi on and off manually until Samsung fix jellybean.
[Galaxy S III General] KennyLegend:
You really are missing out. It's easy to return ur phone to stock if u ever need warranty.

Custom kernels are far superior to stock. Siyah and Perseus kernels have a patch to block multi-cast packets from your router. This could be your saviour.

Read the OP here and see what you think.

Get an app called network signal info free from playstore then then you change settings you can see the drop in WiFi or network then if you do flash kernels you can see a change.
[Galaxy S III General] KennyLegend:
Kernels won't necessarily give u stronger wifi signal but they might make it more stable.

I'll have a look at that app too. ;)

I noticed after installing the app and then shiyah 7.3 my network signal is lower but more stable than 7.1 and WiFi is dropping and increasing at a significant pace.

Don't think new Shiyah is good for me, battery drain is also significant
[Galaxy S III General] XenomorphXx121:
Solved my battery drain at last!

Okay problem was that even at having my screen at half way and having power saving on my screen was showing 95 percent, have no idea why plus other things were taking my battery away.

Cycling my battery helped a little but was losing about 1 percent battery every 2-3 minutes on WiFi and just touching my phone.

So what I did was with titanium backup I just saved my user apps and not system apps then factory reset/wiped my data.

After I restored my user apps now my screen is showing correct percentage and battery is less on WiFi and much much less doing anything else.

So happy :D
[Galaxy S III General] KennyLegend:
So u mean u had previously restored system stuff with titanium as well as user apps??

This is a BIG no-no as you can have system files conflicting with those on the rom you flashed potentially causing any kind of strange behaviour, including but not limited to high battery drain.

With titanium backup, only ever restore user apps, not system apps or data.

Sent from my I9300XXDLJ4
[Galaxy S III General] XenomorphXx121:
Nah always did nandroid backups, was my first time doing a titanium one.

So much better and easier than nandroid
[Galaxy S III General] KennyLegend:
But they don't do the same thing.

Titanium is for backing up apps, app data, widgets etc.

Nandroid is basically a snap shot of your whole rom at the point you backed up.

With titanium, you choose what to backup and what to restore. With a nandroid you restore the whole rom backup which is apps, settings, sms, calls etc.

Don't confuse both.

Titanium is used after a clean installation or factory reset to restore all your apps and a nandroid is used if you get a bootloop from flashing something that doesn't work or from flashing something you don't like. ;)

Sent from my I9300XXDLJ4
[Galaxy S III General] XenomorphXx121:
I know but my nandroid was a bugged nandroid so whenever I restored it I'd restore it back to bugged.

I've had the battery loss since first updating my firmware to jellybean so I'll do a nandroid of my now bug free phone so I know it's now safe :P
[Galaxy S III General] KennyLegend:
But you still shouldn't use titanium for that purpose! U don't ever restore system apps or data.

You should have done a clean install with no titanium restore.

Sent from my I9300XXDLJ4
[Galaxy S III General] XenomorphXx121:
Yeah but it worked and it wasn't my user apps that had the problem it was my system so I just backed up my user apps.

My system apps get updated by google and my contacts get updated by samsung anyway so i've not lost any data and my phone is now perfect so all turned out okay.
[Galaxy S III General] KennyLegend:
I think you're either very confused or I'm just not understanding u properly :confused:

Your system was probably screwed after u restored system stuff.

Google play updates your user apps, not system apps. Or are u talking about Gapps? Either way u don't restore them either.

Maybe I've got the wrong end of the stick here but it sounds like it's pot luck you have everything working correctly.

Sent from my I9300XXDLJ4
[Galaxy S III General] XenomorphXx121:
I know what I'm talking about so it's okay.

Only needed my nandroid 3 times because of a boot loop and two errors I picked up.

I've not tried any roms yet that needed full wipe so I've always stuck to jellybean stock, my phone came with the screen bug and had it since and I really didn't want to go through the hassle of adding my apps back one by one so just backed them up.
[Galaxy S III General] XenomorphXx121:
The jellybean 4.1.2 is good for battery especially using wifi, does drain a little if you have navigation on for google now but I've seen none when I don't have them ticked in settings.

In the last few days my phone has once again started hemorrhaging battery. Stock, 4.1.1, rooted, Meteor IRL. It happened when I first moved from ICS to JB OTA. A factory reset sorted that. Now maybe 3 weeks later same thing started happening 2-3% per hour when phone doing nothing, WiFi off etc etc. No recent updates but came across the Samsung push service. Have frozen it via Titanium and lo and behold it seems to have stabilised the drain. Seems to be a fair amount of chatter online about this service also. Pain in the hole of a thing - only thing with this service frozen you cant use Samsung Dive if you mislay your phone

---------- Post added at 05:32 PM ---------- Previous post was at 05:28 PM ----------

What about non stock diallers - exdialler etc?
[Galaxy S III General] sox978:
I think it's due to the Samsung push service too.

Well and maybe Line and the other same apps.

:crying:
[Galaxy S III General] XenomorphXx121:
Yes I have all my push notifications disabled, even the xda app I'm using now was draining battery as it had notifications on.

Playstore and most games are bad for notifications especially any gameloft games or free games that require ads that causes drain.

Another drain is samsungs very own ad service

Also found changing my router settings to 5ghz was better and faster for wifi with what seems like less drain...not sure yet.
[Galaxy S III General] Galactus:
Hmmmm whatsapp has always been ok for me. Facebook too, just set refresh to manual and receive updates via push. I can easily hit 4 hours screen on over a 24 hour period. My battery is destroyed if I play punch hero though, so addictive lol

[Galaxy S III General] cboss718:
I'm stock, non rooted, and my battery life is amazing on wifi. I had 3 hour screen time, phone unplugged about 10 hours, and I still had 34% left. But my battery when I go out is TERRIBLE. I'm on 4G all day, and my battery drains ridiculously. I check better battery stats and there's no unusual draining. The other day my phone was at 50% after 5.5 hours, with an hour screen time. Can someone please explain this?
[Galaxy S III General] flashflash:
You are right! My battery drain is back to pre jelly bean levels with WiFi on. About 1 pct per hour compared with 4. Thank you for finding this. Since the GPS is only used when apps request GPS, I'm keeping it on!

My S3 drains much faster when using 3G. It is much better when using wifi. Any hint?

Restrct the background data, although 3g will still drain faster than WiFi

No restrict the background data so your apps don't keep updating using your 3g

[Galaxy S III General] amund7:
I'm down to 0.5-0.8%/hr with wifi off, 3g/hdspa on. Google sync on, but now and location services off. Just installed the latest Polish 4.1.2, and zero difference, wifi on= 2,5%/hr

I don't get it. Is this just my phone? Why? What happens? Are some of you able to get below 2%/hr with wifi on? Why am I not?

When I first realized this, on the first stock JB, I tried everything, 3-4 different kernels, different roms. Some were slightly better with wifi, but none were good, where good = less than 1%/hr idling.

Previous JB roms location service and google Now was a crazy battery hog, now it seems to make zero differnce - just wifi on = 2,5%/hr, wifi off (3g on) = 0,5-0,8%

This is obviously not affecting everyone, why??? And why is there no real solution yet??? Siyah is better, but not as good as wifi off. On every other rom before JB, and every other Android phone I've had, Wifi use less battery than 3g.

[Acer Iconia A500] dbaps:
First, thank you for any help you provide.

I've read how to unencrypt my Acer A500. Right now I'm running ICS with Icylicious Rev. 12. I'm sad to see it's not on the site anymore. It's been rock stable.

Anyway I am on the ICS Bootloader 1.031.

If I want to upgrade to Jellybean do I have to remove the encryption? I can't format the /Data partition unless I remove the encryption. I'm just not sure if Jellybean requires me to remove the encryption.

Finally do I need to upgrade the ICS bootloader to a JellyBean bootloader? Is it optional? I found a thread about this but haven't been able to find if it's required, plus the added issue of being encrypted.

Thanks everyone...
[Acer Iconia A500] dibb_nz:
I see over at tegraowners someone unencrypted used a full and proper wipe via cwm recovery here and I see other threads where folks

havent been able to wipe via cwm????

But further reading suggests NOT to change roms UNTIL you un-encrypt so that you are able to wipe yr userdata/cache.

Yes you will also need to install the unlocked bootloader to install JB customs - but the OP will ALWAYS have installation requirements listed so check these first...you may also have some luck posting yr question in the rom thread as well BEFORE doing anything....

civato's v8 unlocked bootloader thread has all the info you need to flash that side of things...

Title pretty much says it all, my gnex says charging but instead of the percentage going up it's dropping at an unreasonable rate. When plugged into my laptop via usb it says usb debugging, and the lockscreen once again says charging, but although I can transfer files as usual the battery percentage still drops. Last night I plugged it into the wall at 30% around 2 AM, when I woke up 5 hours later it was at 0% and died as I looked at it. I have tried 3 different cords and plugs and many outlets.

Ideas?

Best idea: google any question you have, you'll find answers to everything.

Other than that, i would say check the micro usb port in you phone. The middle part is creating a short by touching The metal frame of the port

Use a needle and try to center the middle piece in the port, its touching one of the sides. I had this problem before and fixed it by doing that, be cautious not to break anything.

Hello guys , as you may imagine i am also turned od this nexus 4 device so bad , but unfortunatelly its not available on google store in my country (Montenegro) so i will have to find alternative way to buy it. And that is the problem , there isnt many alternatives left. It will come late to local retailers and providers , and when it comes they will put very high price tag on it. I think it will cost something like 550euros , which is quite high compared to 349 dolars. So if you could pls help me and other ppl , give ideas about how to buy it , without having to wait long or pay extremely more than 349 dolars. Cheers
