Hello Everyone!
I made this thread hoping I can shed some light to those getting very poor battery life. I was also getting very poor battery life, till I went and exchanged my phone for a new one. If you're getting very poor battery life (even after wiping your phone or installing a clean firmware), there is definitely something wrong with your phone or your battery.
I own a i9000m bought from Wireless Wave. I've unlocked the phone and am now using it on Rogers.
My previous phone, I was draining 25% of my battery to just get through 6 hours of standby while I slept. I had juice defender on and autokiller memory optimizer. I turned off all syncing and didn't even use a live wallpaper. My phone was rooted and also had lagfix (which I soon removed). One thing I do remember doing is not charging to 100% when I first got the phone. I did accidentally let it drain to 0% cause I had to use it right away.
After exchanging for a new phone and charging it to 100% right away, I was getting the following results. I have juice defender and nothing else. I changed my band to be WCDMA only. I even have a live wallpaper on. Last night my phone idled for 9 hours and it only drained 2%! Last night going out, I had a moderate to heavy (fbook, 3g, gps, text, youtube) usage pattern on my phone and it only drained 40% after 6 hours of use.
I don't know what else to say, but I'm letting those with battery problems know that the SGS is capable of great battery life. And if all your optimizing and tweaks aren't doing it, then you may want to consider exchanging for a new phone if you still have warranty.
I have a great battery life too in my device compared too the another smartphone i used in the past and now compared to Ip4 and N8 in this devices the bat drain is much higher. So im positive surprised with
the galaxy battery performance, i only use the push email everything else is turned off, livewallpaper and so on..

My phone came with JM7 firmware. My battery life is just excellent, not needing a recharge before a few days with my use
Running JPM here, with darkyy's raw metal ROM, my battery life went up by at least 40% - %50. I was losing 1% per 5 - 10minutes of usage, now its more upwards of half an hour of usage.
I think the phone has very good battery life if you understand what can cause battery drain and adjust it accordingly.
I am now gettining 5% drain per 24 hours on (almost) standby. This would give me about 20 days of standby which is crazy.
Here is my setup:
UK 16 Gb Galaxy S with Eclair JM6 and Voodoo lagfix
Set network to GSM (2g)
Disable internet usage (with APNDroid)
Disable WIFI, Sync Off, GPS Off (with power widgets)
Just before I go to bed, I run Advanced Task Killer and kill anything that doesn't need to be on memory (inlcuding Advanced Task Killer itself).
Using your phone WILL spend a lot of battery. Browsing the internet on 3g is a battery killer. This means that if you do something on your phone that maintains an active 3g connection, it WILL drain your battery in about 3-6 depending on your 3g coverage.
WIFI is better, but again you are looking at something between 6-12 hours of continuous usage, so make sure you only use it when you need it.
Finally, if you need to have your emails the instance they arrive, go for a blackberry because it has the only way of pushing email without maintaining a constant data connection.
I don't need this so I am extremely happy with my phone and the battery life I can get out of it.
I hope this helps.
Have my phone set for 2G with wifi always on.
Use wifi at home.
2G is enough for all normal syncs, and if I need more speed for anything else I temporarily switch to 3G for that.
This way a single charge last me well over 24h under normal usage. Don't even know exactly how much.
With the phone set to 3G, the same usage patern will eat a full charge in something like 8h.

JPM Rom with everything except bluetooth turned on my battery lasted 3 days with low usage (skype a few times and some phone calls and a bit of wifi web-browsing.)
Much better than my wife's iPhone 4... Normally charge it every 2 days.
I am very happy with the phone, just a couple of bug fixes and I would really like it if Swype did some level of contextual checking of words to help minimise unnecessary corrections (perhaps they do already, but it is certainly not well implemented/sophisticated enough).

Eclair for both. No Froyo.
what i wish to have is greater control over the phone, more easily.
Some kind of powertop GUI that let you see the power usage per process.
So you could plain uninstall apps installing ****ty services consuming the battery.
Likewise i'd like *real* control over which background services are running. I mean running an auto killer wtf? Horrible design!
I just want to switch off a service and that it doesnt start again 5 min later thank you very much.
Even the task manager is quite bad. You see last started apps but you don't know which one is running right now. And if its running and backgrounded since a while and you started other apps.. it might very well not even show up in the list anymore. Horrible design again.
Saying all that because stock the phone battery is excellent, installing a couple of popular apps kills it..

Thanks for your prompt reply. Could you check it more precisely on your current SGS? FYI: Settings -> About phone -> Baseband version and Build number or "call" *#1234# -> PDA, PHONE, CSC version numbers. Thanks in advance.

Sure thing. And thanks. KIES offered an update from JM1 baseband and JM2 build version. We'll see how the new ROM performs in about 3 days. Unfortunately don't have spare time to do that sooner. I suspect there's huge difference within the baseband versions.
hey guys.
i have galaxy s i9000..i also had problem of battery.my battery would hardly last 24hrs...i even switched to gsm only mode n switched off sync.but still had same prob..few days back i installed JPJPA firmware..now its wroking fine.lasts more than 35hrs...n also battery charges quickly
Is it possible that the reading on the phone is wrong? When you say you are getting 24 hours are you letting it run flat.
Alternately is it saying the battery is running low and you recharge before it goes flat?
Just wondering if the meter is simply giving incorrect information.
Been 24 hours since last recharge. Lost 6% so far. Running JP6 Froyo. Rooted. Network Data Off. During this 24 hours, just used Angry birds-30mins and ColorDict 5mins. Haven't installed any unnecessary app.
Had lost 1% on standby after 14hrs with no usage. Thats amazing. Very Happy user.
Also want to tell u guys that GPS with active Data connection and Google Maps running and display on took approx 1% of battery every 3mins.
Impossible using stock battery, this phone draws a minimum of 10% battery per hour the screen is on. Its more likely 15-20% with most peoples phone.
Your battery meter may be inaccurate, for example after flashing once my battery stayed at 100% for hours then suddenly shot down to 20%

I use "Battery Indicator" to check my battery status.
My screen is set to turn off and lock after 30 seconds of idling. So it is quite possible to achieve the standby times listed.
Hi, how long do you have holding time of battery, when you are using wi-fi? (browsing)
[Q] Battery life terrible, despite trying all the supposed "fixes", hardware problem?
I got my N4 a bit less than a month ago by this point. I've rooted and tried most ROMS from stock to CM10.1 to PA, etc. However, my battery life is consistently not so good. Coming from a One XL on CM10, I was used to bad battery life, but I expected the N4 to be better.
I don't have any screenshots, but here are my averages:
Time on Battery: 10-14 hours
Screen on: ~1.5 hours (usually, never have gotten over 2.5)
Android OS kept awake: ~1-1.5 hours
I know I'm among the group of people with the problem of Android OS keeping the phone awake, and I see all of these kernels attempting to fix the msm_hsic_wakelock issue, but I'm still having that as well.
I'm always on auto-brightness, Google sync on (calendar, chrome, gmail), Google Now enabled, etc. I'm also always on data, usually 2 bars + (the signal never gets worse than yellow on the battery graph.
Lastly, on wifi, all of these issues are gone. My idle battery drain is also phenomanol on wifi compared to data or even no wifi + no data. In about 8 hours I drained ~8% even with the data off.
Any ideas? I'm getting really frustrated. I see people claiming 2+ hours screen time or 20+ hours on battery on stock phones! I'm nowhere near the average battery times.

Android OS is not keeping your phone awake. It's one of those crappy apps you have installed that are causing a wakelock causing the phone not to deep sleep.
Download: http://forum.xda-developers.com/showthread.php?t=1179809
Use it to debug partial and kernel wakelocks (primarily partial wakelocks). Check CPU states using that app or download CPU Spy from play store.
It needs to be deep sleeping.
Google Now: Disable cards that you dont use.
Turn off auto brightness and adjust it to your liking (CM10.1 has a feature if you long press on status bar it will adjust its brightness so you can do it like that).
Use Franco Kernel r23 (it's the most stable one, if you want to experiment you can try r26).
Google Maps: turn off Google Maps Latitude and its automatic reporting of your location and uncheck auto reporting in your location.
https://play.google.com/store/apps/...xLDEsImNvbS5iaWdleWVzMHgwLnRyaWNrc3Rlcm1vZCJd use that app with Franco Kernel (or buy his app) to adjust its kernel settings.
http://zephik.com/upload/Screenshot_2012-12-14-19-05-58.png is a screenshot from last month. Pretty good battery overall for me.
Press the thanks if I helped. Will reply back if you have any questions or follow ups.
I've been on CM10.1 nightly 1231 for 3 days now and I can happily say that my battery is much better than before.
I've averaging 24-28 hours with 3 hours screen on with data only and usually charging at around 10%.
Always Enabled:
All Location Services
Google Sync
Always Disabled (except when needed):
Google Maps/Latitude location settings
Bluetooth, WiFi, GPS
Google Now cards that I don't normally use
Some things I've noticed:
- When I flash a new ROM and restore my TiBu (flashable zip or regular restore) I find that my battery life is average at best.
- When I flash a new ROM and fresh install my apps from the Play Store my battery life is good to great.
- Third party kernels can sometimes be wonky on this phone. I haven't tried Faux or Franco kernel since flashing 1231 because I've been getting great performance on CM kernel.
- When my kernel CPU is set to "ondemand" the performance is average at best. Changing it to "interactive" has helped improve my battery life... with no other kernel tweaks involved.
Apps like Facebook and Facebook Messenger seem to cause issues with my battery life also. When I was on CM10.1 nightly 1223 I had Facebook Messenger installed and my averages were 12-14 hours off battery. So by eliminating a few apps on fresh ROM installs I've been able to see the different effects they've had on my battery life. Basically any app that uses GPS can potentially be a battery hog even when the phone is not in use.
So from my points above are also some of my takeaways. Try a fresh install and watch what apps you install. Try a few different kernel governors (esp if you're on a custom ROM). You can improve performance by trial and error!
Good luck.
EDIT: zephiK's points above are also valid and I can confirm they've helped my battery life also.

I agree 100% with Facebook. The facebook app sucks your battery life HARD, especially if you plan to have it refreshing intervals. The app continues to request GPS location, so therefore because of that I disable the GPS on my phone completely (its that bug where if u have GPS globally on your phone you see it on the top left of your screen, and it doesnt go away). I leave FB all notifications off and manually sync it by pulling up on news feed. It's either that or check FB via mobile webpage.
Another thing I forgot is your refresh intervals. Make sure your apps don't have it on like syncing every 5/10/15/30/45/60 minutes. Set it to a couple hours more. using a twitter app? instead of having it sync in the background, just manually do it so you get all the missing tweets all at once. No reason to have it sync in the background randomly.
+1 on interactive. on Franco kernel it uses Interactive as it's default governor and it includes a lot of the latest interactive patches that really help out. It also includes qualcomm fixes with msic (not 100% but its better than stock), and newer drivers that will most likely be included in the next OTA.
Thank you for the replies everyone. In regards to all of the fixes you've suggested, I've tried all of them in the past week or two based on hours and hours of reading. This problem even exists on a freshly installed ROM with the bare minimum apps.
Now that I think about it, I wonder if there may be a problem with the radio in my phone. I live on a farm with an AT&T tower, yet I'm only getting "ok" signal, when I should be getting perfect signal. Called Google and just ordered my RMA, seeing as this battery problem has persisted from the day I first loaded up stock 4.2.1 on the phone upon receiving it.
If you constantly have a low signal, that will drain your battery a lot, because it has to boost the signal and that needs a lot more power.

This would have been useful in your original post. Obviously "worse" signal is going to cause more drain on your battery. Hopefully it's just a flaky radio for you but if the replacement has the same issues then it's something else and you should keep at it until you figure it out! That's half the fun with these phones.
My only concern was that he said android os was up there, so that means he has a app preventing his phone from sleeping.
personally i wouldnt take a RMA on poor battery life but as a result due to signal.... but yeah signal does play a huge factor in your battery life
Hello all, I am a new comer here. I have a motorola defy plus mb526.
I've been switching between stock firmware android 2.3.5 and CM10 android 4.1.2 many times since I couldn't manage to make 3G/HSPA work properly (I had signal drops, lower signal strenght and no 3G at all, only HSPA worked well).
So after the 4th or 5th time I came back finally to stock firmware, I noticed my battery lasted less than 12 hours instead of the normal 48 hours duration I had before (both android 2 and 4, with even a slight advantage towards android 2).
My battery stats seem to point that my IDLE/Inactive phone consumed 35%, against only a 9% corresponding to the screen consumption. I am 70% of the time connected to WIFI, and sometimes I connect to 3G. It seems my phone is consuming a lot battery when IDLE.
Do you have any suggestions on how to diagnose this issue??
What I did until now:
>> Installed a new battery stats app more detailed
>> Waiting for the battery to clean up, to wipe battery stats and see if that helps (I did it before I installed the new rom though)
Thank you and sorry for my english
JV
First off, for the signal issue you could've changed the baseband from settings/advanced.
And for battery usage problem try a clean sbf flash and wipe data. Then install those apps only which you used earlier when battery life was good. If you get the same level of performance then one of the newer apps is messing with the deep sleep.
Also charge your phone for a couple is hours at 100% to calibrate battery properly

Thanks for the reply, I've been doing some tests and finally decided to go back to quarx CM10. I'm in argentina so 3G pretty much sucks. But i'm gonna have patience and try to make it work.
Apart from this, unfortunately, battery is still down. But I have a new theory. The same day I started experiencing low battery duration (plus the same day I overclocked the phone and flashed it), I removed the screen block (so there was no password or slide needed when turning the screen on), I think that could have been the reason behind the "Inactive/Idle phone" consuming more battery than the screen itself.
I have reverted this and battery seems to last longer (still seems far from the old 48 hours duration =*( ), plus the battery stats no longer report that inactive phone consumes more than screen.
I will be keeping on the diagnostics and hope its not the battery hardware but some crappy battery stats on my phone
Thanks

Get setvsl, and change the battery usage... keep ur phone cool, check the temprature with battery solo widget
turn off data when not in use, us 2G if possible.. lower the brightness....

LG G3 Screen on Time Discussion
Greetings all.
Firstly, this is not a thread to discuss resolution changing! There are several of those already and it has been established that it does not have a viable effect on battery life!
I started this thread as I thought we could use a useful thread which we will discuss SOLEY (SOT) screen on time. After sifting through the rather disorganised battery life discussions I was left with mixed ideas of what a general screen on time for the LG G3 was. There are of course several of these battery threads, but as they all talk about all aspects of battery life, standby included, I thought it would be nice to get some ideas of SOT congregating in one thread.
Format
First of all there needs to be a format in which we standardise our discussion. If you are going to post complaining about SOT or saying how great your SOT is please format your post like so. I propose the following.
Model:
Rom and Version/Kernel:
Modem/Baseband:
Carrier/Country:
GPS:
WIFI:
Data (4g/3g/2g/none):
Explanation of use/modifications:
Screenshots (3% or below):
Would you please state in the explanation, your use of battery saving apps such as Greenify, Amplify, Automatic Data toggles, Tasker, Xposed and so on. Note any messaging/email clients installed as these will have an obvious effect on SOT. What are your syncing settings? For the screen shots post any that seem interesting but a 3% or below is preferred. Mention something about your use, if it was gaming, web browsing, listening to music, or with a long period of standby time. Also please state an aproximation of your brightness settings plus any debloating that you have done, and anything else you think is of relevance!
This is the proposed format for posting. We should be able to get a fantastic database of SOT for the LG G3.
I do realise that everyone's usage differs greatly and it will vary according to brightness, location and many different factors such as how long the phone has been in standby etcetera.. But don't let that stop you posting. I will start.
My Screen on TimeModel: D855
Rom and Version/Kernel: Cloudy 2.5 and kernel
Modem/Baseband: 20P
Carrier/Country: Telecom Italia
GPS: No
WIFI: No
Data (4g/3g/2g/none): 3G on constantly
Explanation of use/modifications: Fast dormancy disabled. All the bloatware frozen with titanium back up. Whats app was the only IM installed plus skype. Screen brightness was roughly below 60% almost the whole time on auto. No gaming. Music listening for 20min, reading xda for the majority of the time, plus a bit of downtime for dinner. No greenify, amplify or data toggles. Purely let it run how it goes. Although I did have the sharpening set to disabled. My signal was around 2 bars for most of the time and my sync for everything was disabled, contacts, all google sync stuff. I had also disabled back ground data for the Google Play Store, which results in a pop up error, but this can be fixed by exiting and resarting the Play Store.

Now thats inpressive. Do you live next to a cell phone tower? Or have an extended battery or what! Thats some impressive screen on time. Do you think you could get more?
This phone has such variation with SOT. More than my old S4, that had maybe 1 hour difference between users at most. But 7 hours SOT!?! What apps do you have installed/not installed. I'm going to flash your setup! That's utterly incredible!

My cell signal is normally 2-3 bars so not especially strong. Just the stock original battery, around 6 months old at this point.
I have installed nova launcher, basic Google apps, poweramp, chrome, just typical everyday stuff. Removed everything LG except quickremote and quick note.
Could probably push over 8 hours if I underclocked more and messed about with custom kernels but I want to maintain the performance and stability I have.
I don't know how you guys can get 5 hours SOT.I barely get 4 hours sot and that too only on wifi.
Location is turned off,gestures off.Bright ess always on 35%.
I use whatsapp,fb,tapatalk and youtube.Little bit of gaming.
I have a used d855 and it was from an australian carrier "Optus" but i have flashed v20u kdz,rooted and using gabriel kernel.
I don't know if it's battery have got weaker.It's one terminal has gone somewhat black but other three are fine.

That is still phenomenal. I cannot comprehend having 7+ hours of SOT. It really is the only real gauge of battery life. At least for me. Idle battery drain is easily fixed by controlling wakelocks, but SOT is the main thing that I look for in a smart phone.
Before I bought this phone, which was about a week ago, I was impressed by 5 hours SOT, but knowing that this phone can have upwards of 7 hours makes me want to look into this issue more. It doesnt make sense to me. Do you have a BBS log from these screen on times?
Was your update OTA? I assume so. I currently don't have any wifi so I'm going to search for a hotspot, download the firmware from the XDA thread, flash it and see how I go. I am in Italy so it could be interesting.

The gaming really kills it. The GPU has a time with the screen. At least thats what I have found. I did about 20 min of that Shark Game to test out the phone and got 5 hours + SOT by 2% remaining. Facebook wont be helping. Whatsapp doesn't seem to be a problem for me on the drain side. It drains a bit, but not alot. Also does Optus support Fast Dormancy? If not its probably best to disable it.
Remeber to post in the above format so we can start to piece together the perfect combinations!

Wow guys, your phones are like beasts. I've never ever have gotten 4hr+ SOT on my G3. Nowadays I usually get 2,5 hrs with 40+ hrs of total battery time. I have no idea how you're doing it. I've tried to find the culprit, but everything seems normal. Atleast that's what apps tell me. Can you please help me find the issue? Give me tips?

Wow guys, your phones are like beasts. I've never ever have gotten 4hr+ SOT on my G3. Nowadays I usually get 2,5 hrs with 40+ hrs of total battery time. I have no idea how you're doing it. I've tried to find the culprit, but everything seems normal. Atleast that's what apps tell me. Can you please help me find the issue? Give me tips?

And you say you are getting around 4 hours SOT? So you are running Cloudy like me, I'm not entirely sure yet, but it seems to me that it could infact be worse than some versions of stock, for screen on time. I'm currently out of Wifi so I have not yet had the chance to flash the 20U stock. I want to try it with my exact set up and see how I go.
That is strange, 4 hours SOT. It's not alot. I have auto sync disabled, along with every google syncing aplication under accounts disabled so nothing syncs. I also disabled back ground data for the Google Play store, which causes an abort dialog sometimes, but it is easily fixed by exiting the app, swiping it from recents and starting it again.
I also have my 3G set to only 3G whichvis annoyingly changed to auto on a reboot. But this certainly helps. As for modems how is your cell signal battery consumption under stock battery info? Whats your period of no signal? Of course, all those messaging apps probably ruin your SOT as most of them are polling all the time, at least try congregating all your messaging into one app, and make sure that app isn't messenger.
Also are you sure your carrier doesn't support FD? Are you getting massive phone wakelocks when FD is enabled?

4 hours of SOT would be awesome for me. As I said it's only 2,5 hours nowadays. I got Gmail syncing all the time as it's essential for my work. There isn't any time without signal but the phone idle and cell standby is right under the screen in consumption with 10-15% each. My phone sleeps well, almost no battery usage while the screen is off. But as soon as I turn on the screen it goes crazy and consumes battery like mad. Messenger must be a huge battery drain but I used to have the 4 hrs of SOT even 5 on lighter days with messenger. I don't think my carrier support FD. It's a small country without any really advanced tech.

Well it seems to me that your problem would be your modem/baseband/radio. If cell standby is up there with screen, I would assume that your phone doesn't have great reception. I say this because, supposing you have your screen off for a long period yet the radio isn't communicating that much data, but then once you turn the screen on, I'm going to assume that you are using the internet for browsing or responding to emails, messages ect? I would think that this would mean the phone must send alot more data with a bad signal, which could suggest why your standby times are fine and you SOT times aren't so good. 3G is definetly the way to go for SOT, you have no chance on 4G. Try enabling FD and seeing if phone starts having wakelocks in Better Battery Stats.
I also advise that you swap out Gmail for something a bit less ruthlessly active on the syncing side of things. I use stock, some people like others like cloudmagic, but there are a billion so try them out. Something that you can at least customise more to be push or pull and not syncing every 5 min. You can probably also disable all of the google account syncing tasks. Download greenify, and it has a setting there that allows you to see all the hidden Google services syncing tasks under accounts. I find that is one of the best things about Greenify. I don't use it for freezing apps, but that setting helps stop your phone syncing every second. For example who cares about chrome bookmarks syncing? Not me.
Edit: Sorry I just read that again. 2.5 hours S0T. That is utterly horrendous. Attach a BBS log.

Sorry for the delay answer and thanks for you help so far. I've tried out your Greenify tips and install a more recent version of the kernel i'm running now as it was having battery drain issues. Also I noticed someting weird in BBS. Please see my attachment.
"No or unknown signal" 100%. Is it normal? Can it be the issue?

Nah, I don't think so. Unless you actually have no reception? I get that too sometimes. I'm not sure if it is a bug or what it is, but if you had signal the whole time then you can probably ignore it. I had that too and wondered what it was. Never found out.
Also make sure you have your data set to 3G not auto and manually select your provider under cellphone networks. Because I have a feeling if you say you want to stay on the same one, you wont have it trying to switch when the signal gets low from that provider, it will just go to no signal. I'm not sure about your carrier, but some carriers have a switch over agreement with other carriers, which would make your signal reception reporting not entirely accurate. If you select one provider. It will always be that one provider
Here you go I will attach one of my BBS logs from when I got more than 5 hours SOT.

No, here in Hungary there is no agreement. It will only stay on my provider. Our 4G and 2G coverage is great but the 3G one is not so. I need to have 2g on too. Usually I got 2 or 3 bars at home. While in the city it really depends. Sometimes barely any signal, then all of a sudden max bars. Maybe my battery is faulty?
Edit: Also you got No or Unknown Signal (): 11 m 21 s 2.1% while I got 100%. I need to figure this one out.

Yes I noticed that too. Interesting. I suppose that you could try a new modem? Perhaps that would help your 3g signal?

I changed modem, now I'm waiting for results. So far better. Also I noticed one more thing. My battery charges itself overnight. I went to sleep with 50% remaining when I woke up it went up to 52%. This happens very often. Also, when I'm using it under 30% it discharges even faster. Is it the battery or it's just miscalibrated? I've tried calibrating it by draining it almost to 0 then turned it off and offline charged it until it was full. Never worked. Anymore tricks?

Yeah, I noticed the exact same phenomenon actually, draining speeding up from 30%. I made a thread about it but no one took any interest. I read somewhere that perhaps LG does it to create a false sense of better battery. I would like to find the problem here though, because it is a rather annoying problem. Having inaccurate battery readings under 30% is the last thing you want. Perhaps they made it like that to make the battery saver feature seem like it is doing more than it really is?
As for charging over night I had that too on some other devices. I think it is a common bug across android or general lion batteries, because it's not uncommon to hear about. I'm sure there is a lot of discussion out there about it. Still, two percent is rather nice to gain over night without charging!
One more question, are you using the stock charger?
I got a S4 i9505 with albe95 S6 port ROM. I've tweaked the settings to pretty much disable all background activity so there's no syncing, no GPS, no bluetooth no NFC etc. I've got airplane mode on 24/7 with WiFi turned on. I've also installed Greenify and System Tuner Pro (I have root) and disabled a few GooglePlayServices services and stuff. Followed a tutorial for that. Looking at the settings app, I've got 40% battery remaining and have been on battery for 2 hours 40 minutes. Probably slept for 30-45 minutes and when it was on, I go on chrome, mess with Theme engine and some other light stuff. Now I just waited 20-30 minutes and it drained 4% screen off. I waited 5 minutes and it drained 1%. Is there an app that runs in the background and I leave my phone screen off overnight to tell me what processes are using the most battery and then disable those processes? I've tried to google it but none have helped. I've disabled Gtalk and a bunch of other processes, no luck. About to download Titanium and mess around with Greenify a bit more. I'm new to Android, reason I don't like Android is it's battery life. My iPod touch 5's 910mAh battery lasts 5 hours watching YouTube, surfing the web and light gaming (Clash of Clans) while the S4's 2600 mAh battery lasts 3-4 hours. Triple the size but less battery life?
Android's root is a lot more complicated than iOS, we just go to Cydia and download tweaks like an app from the Play Store. But yeah, any apps you guys use to check background processes using battery?
It's called BetterBatteryStats.
I don't think you will find it on the play store. Or if it's free there. There is a free version on the forums here. And I mean free, not cracked or anything.
And there's more to battery life than just mAh. Your iPod has a smaller screen and a smaller resolution. Which means less work for the GPU.

Right so I messed around with BBS and I discovered the different tabs. Looked at Kernel wakelocks and Partial wakelocks. Did some research and PowerManagementService is a big one. Was told to go to partial wakelock and found RILS and RILJ0. Did some more research on that and it's related to radio and wireless stuff. (Radio Interface Layer) Did some MORE research and apparently my modem is the problem. Someone suggested me to get "GetRIL" from Play Store and see if the two ... things match but GetRIL either isn't compatible or it doesn't work. Now problem is, I have Airplane mode on 24/7 and WiFi enabled so cellular should b turned off, right?
With airplane mode on yes, network should be turned off.
The modem can be changed anyway. So maybe you just have to update the modem.
Also try a different rom.

I read that ROMS and kernels have no affect on battery life other than disabling sync and background stuff in the settings app. Only time it will affect battery life is if it's badly written.
So if cellular is turned off, why is "Cell Standby" the second most draining thing behind "Screen"? All the websites I looked at just say "Turn airplane on and wifi on" but what I'm really looking for is to completely disable cellular with "System Tuner", or do something with root permissions to force stop cellular. I've got no SIM card installed.
Not true. Both kernel and ROM can have a significant effect on battery life. For the kernel, a custom kernel can improve battery life by allowing the processor to be undervolted, thus using less power per CPU cycle. The ROM could also have battery-saving features, e.g. Doze in Android 6.0. The ROM could also have battery-sapping bugs.
The modem is separate from the ROM and kernel. It will have its own enhancements and is updated frequently, so you should update it.
If you dial *#*#4636#*#* you should get to a menu where you have the option to turn off radio. But that's probably the same thing as airplane mode.
And roms and kernels do have an impact on battery life. I once flashed a kernel that drained my battery very quickly. The same rom without that kernel was fine and with great battery life.
So, as I said, consider changing your rom. Just to see if it is rom related or not.

I updated my modem and bootloader from the same thread as my ROM, not sure if it did anything but I've managed to raise battery life from ~4 hours to ~7 hours just non-stop google chrome, theme-ing, downloading apps and trying to get better battery life. Also watched some YouTube videos.
I actually flashed this ROM because of themes, specifically the Avengers theme. Also there's a few pure black themes, did some research and pure black actually gives your battery ~40% more juice. Real world usage will probably be at least 15-20% more battery. But I'm still trying to find out how to fully disable cellular, anybody know? I've got root and Titanium Backup. I'm not sure what to freeze though and "Cell standby" continues to be the second most draining thing in the settings app.

Dialing that says "Not registered with network" because I have no SIM installed. Cellular would kill my battery but even without a SIM, cellular still is active because of emergency.
I've googled everything I can think of, within 2 days I've increased my battery by at least 60% but cellular is driving me nuts. It's using ~20 of my battery while using my phone, that's 20% plus another ~20% once I find a way to get a pure black theme that works in third-party apps as well for my AMOLED display. Also, titanium backup isn't able to convert Google Play Services or GSF into a app so I can greenify it. It just processes and processes.
There is no theme that can make all apps black. Dark material makes many apps pitch black, but it's for CM based roms only.
You can get the pro version of greenify and maybe xposed. Then you can greenify system apps. Including Google play stuff. But greenify works only when screen is off. When screen is on, the greenified apps will run again.
Or use titanium backup to freeze everything Google play related, until you need it. But doing so will require you to input your gmail account again.
You might also freeze the phone app and anything else related to network. Since you're not going to use the phone for calls. Maybe that will solve cell issue.
Right, I have no idea how I did it but my phone for the past hour and a half has not dropped a single percent and has mostly been in deep sleep. No more wakelocks too, only thing I noticed was a alarm from Google in BBS but didn't mind that too much. Excited to see how much it will drop overnight.
Also, do you know the largest battery for the S4 that I can buy on amazon.ca? I don't want a case or a separate battery, I just want a battery that's more than 2600 mAh. So far, I think the ZeroLemon 3000 mAh battery is the biggest but I heard it's got no NFC. I don't use NFC or anything wireless other than WiFi but could you give me a quick explanation of what this does cause apparently it's a part of the battery itself.
You know that thing where you put two phones together (back to back) and it transfers data from one phone to the other? That is NFC. You can basically send web pages, app pages in the google play store and phone numbers with it. Just bring whatever you want to send on the screen and touch your phone on another phone to send it.
You can't sent actual apps and files.
The connection is established through connectors on the battery. That's why it won't work if the battery doesn't have one. It also is a method to verify the autenticity of batteries. Fake batteries don't usually have working NFC.
Now, the biggest S4 battery I heard of is about 9000 mAh. The second is 7500 mAh. I don't know if you can find them on Amazon.ca.
Use amplify and limit all "safe to limit" wakelocks.
