Hi! I wanted to know if you guys have a problem with the battery life on SwiftDroid RC5. I have a poor battery life and therefore big battery problems.
i had mine and bought a new batt no probs after that
Yes, I do. Since RC4 and RC5 I have very poor battery life. Before it was enough to charge once every other day, now I have to do it daily.
Actually after installing RC5 it was a disaster as battery didn't keep even 24 hours but after recalibration it's better. But even then during the course of the day while doing basically nothing (say, sending and receiving 3 or 4 sms) it goes down from 99% to 40%.
Edit: I should mention that I overclocked to 800MHz, but I used to do it before RC4.

Same here. I'm moving on Cyanogenmod 6.
yeah swiftdroid is a real battery drainer but
on swiftdroid on average my battery lasted 2 days..
but still i use cyan6!!
good in battery and performance!!
Same here. Experiencing battery problems on SwiftDroid aswell. Like mentioned above the battery drains even when doing nothing. Experience this on basically any mod built on SwifDroid ofcourse. Changed to EleganceSwift, waiting for mike to release AOSP with Bluetooth-free radio ;-)
There's something more to it.
Recently I was playing a bit with my phone, installed couple of applications and then suddenly I realized that battery doesn't drain as fast as it used to. One thing I noted is that for example Videos application doesn't reside in memory anymore. I'm not saying this one was the sole battery hog but I'm starting to suspect that those cases of battery going down very fast may be related to some misbehaving app or apps and not necessarily be Gingerbread's fault.
If that's the case, the solution would be, I imagine, to trim system preferences to have such apps killed fast not to let them stay active.
using ASIS atm, but when I was using RC5 I didn't notice much faster draining. Still, it depends how many apps are running on your device and did you overclock it? I used to have min 250MHz, max 600MHz and it was pretty fine with texting, multiple apps running and music. Now with min 825MHz/max 825MHz it's draining faster ofc
Well,I remember a day when i update to SwiftDroid RC5, the batter drains and there isnt any app running in background after that i changed to a another rom.
btw fdespotovski, Multiverse is my favorite rom, in fact, i wrote on the offcial blog but i have problems with the RC3, statusbar sound widget doesnt work properly for now im on RC2
O.O cant stand the bad battery life of 2.2 or 2.3 so back to the old 2.1 im now using this

I'm not using ASIS, still at RC5, and what I reported is that both RC5 and RC4 drain battery much faster than earlier versions. Assuming ASIS is just cosmetic change to RC5 it doesn't surprise me you didn't notice any difference. And again, I do overclock to 800MHz and I do it since M5 if memory serves me well. I know principles of overclocking and I know, and accept, drawbacks that come with it. But when at the same clock RC3 can live two days or more while sometimes RC5 barely manages only one then I suspect something is not right.
I tried to check which applications are responsible for battery drain but system report is not helping when telling that 98% took Android system, 2% cell standby and 2% phone idle.
Sorry for necroposting but I didn't want to litter forum with new thread and the problem itself hasn't go away.
I'm still using SwiftDroid v2.0 RC5 and until recently I still had problem of battery barely keeping one day: whole night on the charger and after moderate to no use during the day on the evening it was almost drained.
Recently I installed one more application (rather unrelated, I'd need really solid proof that CPU Spy directly improves energy usage) and after that the battery easily keeps for two days. Which brings back the theory I have that the short battery life is not necessarily caused by Android itself but by some applications staying in memory and not sleeping properly. If so, installing extra app may help just for this reason that it having higher priority will swap out those misbehaving ones.
Thus I propose little hunt, if anyone's interested. I'd like to stay focused on v2.0 RC5 (maybe RC4/ASIS if you believe the difference is not too big). I need reported both GOOD and BAD battery life. In either case please write down all apps currently in memory (you can skip those you have installed, I'm mostly interested in what comes from ROM). And don't forget to mention which actual version do you use and whether it's good or bad case.
Given some meaningful data I hope to isolate which apps cause excessive battery drainage. I'm not sure what to do with that information next but I think it would be good start anyway.
To make said start, here's what I have:
SwiftDroid 2.0 RC5 / GOOD battery
- DSP Manager
- Usage Timelines Free
- Doit.im
- K-9 Mail
- Auto Memory Manager
- Superuser
- Settings
- TM World Clock
- Go launcher EX (doesn't report itself as staying in memory but I suppose it has to be running somewhere)
custom roms...with gingerbread will definately have faster battery usage!! u cant help it
---------- Post added at 10:33 PM ---------- Previous post was at 10:31 PM ----------
use stock roms.... if u want good battery life!
Guys help please, I have a battery/charging problem after installing RC5, this is my first ever custom ROM, it worked great yesterday, but after charging it over night I'm stuck at 99% it won't go up nor down, the phone won't charge and it won't even connect to PC via USB I tried turning it off completely and then plugged in the charger but it just booted up (is it supposed to do that this is my first android?) and that was it. Everything else works fine, wifi etc.... Is there a way to fix this ? I can't transfer a new custom rom to the sd when it won't connect to the PC

the battery stuck at 99 % is a often coming bug and i don't know any solutions mine goes to 97 % ...
ehen phone is shut down and you plug the charger its normal that its booting(because of fastboot)
connection to pc should work, try another port re-install the drivers
thanks ...............
I also have a battery problem... i have installed this ROM 3 days ago, and now i can't charge my battery over 45-55%. Phone was charging all night long, and batter lasted for a day and a half, but its annoying... btw, what now, do I delete battstats now at 55%, when i can not charge phone to 100%?
I have read little about this issue . Instead of renaming or deleting files can we make auto booting script to kill this process so it will no longer looking for a mobile data ?
I have no android skills so am asking somebody who have it. Maybe there is other safe way to ged ride of that battery eating cell standby process

PS
I have try
(Without doing nothing 50% SCREEN AND WIFI TOGETHER 40 % after change a charg iconia to 100 % and wiape battery stats)
2g/3g mobile data switching best results cel standby takkes only 35% battery
Kill mobile data and prevent to run almost same thing
Cheat with airplne mode same thing
Try to download from market a.k.a batery saver for acer iconia without any results (thor mod with i have is based on assus transformer and market shows incompatible version?)
Dear Pavel,
this is a rather old issue, solved long time ago. You can just add the following lines in your build.prop file, located in the system folder:
ro.carrier=wifi-only
Thor's ROM features this tweak by default so you don't have to do anything - no cell standby.
Well thor rom have this line indeed. And when U check settings about tablet battery indeed isnot showing .
When U install any other app to show battery stats actually shows cell standby and phone idle. I using norton utilities but few other ones shows.
I left for a night tablet screen off, gps off , wi fi on, airplanemode on and after 6h i have 15 % drop down. 8 H on my iconia possible when everithing is off.
Ps
Writing this post 3% down... and tablet was bought on black friday is brand new is that normal ?

If your tablet is new did you fully charge and then discharge the battery to about where it auto shuts off.

There are a couple of things to mention. If you are running an over clocked processor, this will of course use more battery power. Especially with thors roms, because the last time I looked, depending on version, it installed over clocked to 1.5ghz. If you don't need that much, try setting it to 1.2 for example.
Apps that are always running and synching. Things like weather apps, mail, fb, etc. And... those lovely battery apps (a waste of time). And this also includes Norton, as it runs as a process. All of these use battery power.
And as briandigital said, let the battery get a few full changes. Usually takes them about a week to settle down.
I agree with U. Those apps using battery. For example weather widget 0.5 % or norton 0.5 % but still shows 60 + % cell standby or 2% phone idle. wifi over night 30 % with checking mail every 15 min.
Over Clocking got nothing to do with this (1000 on screen on 400 on off) system proces phone is running all the time draining battery.
I have thor 14.2 mod and to get 100 % shure I flash again kernel and dubble chec for wifi-only line.
Wipe battery stats and 10 min after cell stanby 30 % after 30 back to 63 %
Or 5 diffrent apps from market are wrong showing cell standby and system process phone working and draining battery or this all solutins are not really working. If it not showing on /settings /battery is not mean process is not working
Anybody know how to kill that process and prevent to run ?
so can write small script to kill it"

I'll ask you a silly question.
And only because I didn't see it stated anywhere (or I missed it)
Are you running an A500? or an A501?
3g USB Dongle?
Did you run any "update patches" concerning 3g Dongle support?
Reason I ask, is that I did some of the testing for the kernel version you are using. (3.9r3). And frankly, I haven't heard a lot of 500 users complain about "cell standby" with the 14Rom. In fact the combo should be giving you extremely good battery life.
You said it only shows cell standby when using some other different application? I might suggest the app is not telling the truth.
Typically, losing 10% overnight with wifi on, is pretty normal. During testing, I lost 8% on internal 3g, and about 10 or 11 with Wifi. FB and Mail not's set to 1hr intervals. WX at 3hrs.
The fact you still have the menu system for mobile networks (2g/3g) is very puzzling......
Did you post this issue on Thor's site? www.tegraowners.com

2. No any addons clear tablet nothing plugin, kernel and rom from thor14v2
3. No any updadtes
4. Am not complaining about battery life, am complaining about stupid process what is draning my battery.
5. A can post 5 screenshoots of different apps whitch showing cell standby process draining battery. Whatever i will download from market kit is showing same so i believe they're not wrong.

You should re-think about posting on Thor's site. He's typically pretty responsive. Unless it's a stupid question, or somebody's not nice.
The cell standby issue is an old one. It's because the 500 and 501 share the same hardware with the exception of internal 3g for the 501. And because of that, the share mostly the same OS code.
Thors rom, was based on the asus transformer. I don't run it, as it doesnt fully support internal 3g.
It's possible, that the process is still running, only hidden from view based on the images you supplied with the modified build.prop set to wifi-only.
In this case, I would ask you again, to post the issue on Thors FORUM under the Rom ver 14 topic. It may take him a day to answer, as he's working on ICS right now.
In the meantime, here at xda in the a500 forum, there are several "older" topics covering cell standby on the a500. One of the fixes at the time, was to "freeze" the telephoney.apk (get some error messages) then reboot.
Just do a search for cell standby, and you'll find them. I found them earlier today through Google (but can't remember where), so you should be able to do the same.
Well I did some research before I bother U and other solutions is to rename / remove phone.apk witch may solid brick my acer. Am wonder if I rename it and hard reset can I be able go to recovery ? And restore prev backup or this is gonna be a perm brick
Sent from my HTC Vision using xda premium
Well Pavil, those posts are a little old.
And, sometimes people call things a "brick" when they really don't know what a brick is
BEFORE I would rename any apps, I would try this, Install Titanium backup. Once installed, and root granted of course, Select the telephony apk, then do a "freeze" on it. Reboot and check things. You may want to freeze those other couple apk's if it doesn't fix it. You will probably get some error messages when you first freeze it, but ignore it, and reboot.
But BEFORE you go freezing things, do a recovery backup first This way, you can get back to where you were before freezing.
Then see how things go.
EDIT. Stop using battery apps designed for phones. They may run on Honeycomb, but if they were designed for devices that have a functioning radio, they know no better than to display an erronous stat.
But honestly, battery stats in android are somewhat misinterpreted.
Example. If your device used 10% power. And the stat says Display used 80%, It means that of that 10%, the display was responsible for 80% of it. Not 80% total battery power.
In the meantime, I see you didn't post on thors site? Ok, I'm on good terms with him, so I'll pose the question to him.
Thanks for interesting of my problem. I try today to ps ,get pid and kill but this buster is restarting by it self...
Well i will wait for re ftom Thor and ICS. We will see...

It appears from your screen shots that you don't have your wifi set to disconnect when your screen goes off. I could be mistaken, but if it's not, changing that will help battery life immensely

Yeah, no sense in messing things up. A pity I don't have an a500 or I'd test it myself.
You could try flashing one of the other roms, and see if the result is the same. For example Taboonay. I ran it for quite awhile with Thors 3.9r3 kernel. Or you can use the kernel it comes with.
Answer from Thor is that he's not aware of the cell.standby issue as nobody else has mentioned it, and all his stuff now is set up for ICS, so he doesn't have the time to check it out.
So, maybe you just have to live with it. Seems your battery life is ok, so I would just ignore it for now.
Did you wipe your battery stats from CWM before flashing?... And by the way thor's ROM has CPU clock set to 1.2 GHz by default.
p. s. Moscow Desire is right about apps made for phones.

Yeah, he had to back off the original cpu install recently due to a couple users couldn't flash at that speed (1.5). Not all CPU's are made equal.
(the real issue here, is the old "cell standby" issue that a500's had in the past)
But again, like drkalo affirms, you shouldn't be using battery apps that were designed for phones running android 2.3. I suspect (considering nobody else using Thors roms complain about cell standby), that the phone battery apps have this hard coded, and expect it to be there, so it displays a random percentage. Probably because it see's the phone apk's in the OS and naturally assumes it needs to display something.
Yes, the apps will mostly function on Honeycomb, but, are they really made for tablets? Probably not. (even if they say it does).

So what to use to check ral battery / process usage?
Sent from my EPAD using xda premium
Personally Pavil, I do not use one. Except what comes in the rom. There's really no need to get anything else. And frankly, I don't hear a lot about folks running 3rd party battery apps on their tablets. So I'm not going to be much help on suggesting one. I just know most of the task and battery apps, were designed for phones on android 2.3.
I gave up on things like battery apps, task killers, task monitors and the likes a long time ago. I learned to manage things on my own like most others do. There's no reason, once you learn a little about how android works, to add apps that take even more resources.
Bottom line, you can have every app in the world to monitor things, but what really matters, is what the "actual" battery life is.
For example, I can go 12hrs with normal usage, and still have 60%. This includes internet, sms, mail a few times, maybe some video for an hour. It depends.
Or, I can play angry birds 7 hrs straight before recharge. Not bad! And I run my processor at 1500ghz.
You can instal a cpu app, like cpumaster, and set profiles based on how much battery you have left. I typicaly set mine to start at 1500ghz, then do 2 extras to down the speed based on battery. When I use them, I can run for almost 3 days with normal usage. I do this when I know I will be camping with no electricity.
I have 4 of these profiles on my phone, and the longest I lasted, was almost 4 days before recharge.
Wish I could help you more.
First and foremost this guide is based around the Sprint Nexus S 4G. If you do not have the Nexus S 4G, Than this guide will probably not help you. =)
Secondly all credit goes to the wonderful people that work endlessly to make these wonderful Roms and Kernels. Without you guys Android wouldn't be what it is today!
Third: Please make a back up and use this guide at your own risk. I don't want to bare the weight of someone turning their phone into a paperweight by using this guide.
Alright, Now lets get to the fun part.
Case you've already forgotten why you're ready this topic. This is my rough how-to guide on getting easily over 2 days out of a single charge on your phone, Very much possible to push 3 or more days depending on use and other varying factors.
What you're going to need to start:
- Rooted Nexus S 4G with a custom recovery like Clockwork mod.
- Flash the following Rom http://forum.xda-developers.com/showthread.php?t=1417499
- Flash the following Kernel http://forum.xda-developers.com/showthread.php?t=1436313
-Flash the following "KL2" Radio update http://forum.xda-developers.com/showthread.php?t=1077168
After you have flashed all the above and confirmed your phone is running stable with all the default settings. Charge your phone to 100% and reboot back into recovery, and WIPE YOUR BATTERY STATS
Now. Lets begin configuring your rom and kernel!
- Install CPU MASTER FREE from the android market https://market.android.com/details?id=com.antutu.CpuMasterFree&hl=en
Set the following on CPU Master
- CPU Speed 800 MAX and 100MIN
- CPU Governor CONSERVATIVE
- and Scheduler set to CFQ
- Make sure to click apply on boot as well
- Now Install NSTOOLS from the Android market https://market.android.com/details?id=mobi.cyann.nstools&feature=search_result
Set the following on NSTOOLS
- DEEP IDLE: ENABLED
- Backlight Dimmer: ENABLED
- Make sure Backlight Notifications are left disabled. It keeps phone from idling properly.
- Leave all other settings alone and make sure to check set on boot
- Now lastly install Antutu Battery Saver from the Android Market
https://market.android.com/details?id=com.antutu.powersaver&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5hbnR1dHUucG93ZXJzYXZlciJd
Activate Battery Saver and set to level 2 battery save. Easy as that.
Basically your done! =)
If you notice your phone has a slightly worse or little to no improvement on the battery this is due to you deleting your battery stats. As you use your phone it will write new stats and you will begin to notice a difference after a few cycles. Just make sure your battery is charged when you wipe them, Let the phone run almost completely dead. Plug it up, Let it charge back to 100%, Unplug it. Rinse and repeat. Just be sure to unplug it when you notice it's fully charged even if you don't plan on going anywhere. Just let it sit and run on battery so that it calibrates the battery stats while it's idle as well.
Now as you should already know your battery life is going to heavily depend on use and SIGNAL STRENGTH. It seems a lot of people don't realize the more signal you have the longer your battery will last. If you're in an area with very low signal it can kill your phone in a matter of hours.
I have attached a screen shot of my battery life using this above method. Other settings I will mention
- WIFI ENABLED and CONNECTED
- Bluetooth and NFC DISABLED
- Automatic backlight control enabled
- Facebook notifcations, Weather and Contacts are the only things set to SYNC on my phone.
- Usage: Light to moderate. This includes a few texts throughout the day. A few phone calls, and a brief checking of facebook every now and then.
If I'm missing anything I will update this post. That is all for now. Happy modding and may this tutorial work the same wonders for you as it did me.
Also I should state that the phone finally died at around 2Days 17hrs on battery. My goal for 3 straight days was cut short after a few 30 minute phone calls and other work I had to do on the phone.
If you have any questions. Feel free to post, or PM me. I'll be here =)

- Bluetooth and NFC DISABLED
- Automatic backlight control enabled
- Facebook notifcations, Weather and Contacts are the only things set to SYNC on my phone.
- Usage: Light to moderate. This includes a few texts throughout the day. A few phone calls, and a brief checking of facebook every now and then.
If I'm missing anything I will update this post. That is all for now. Happy modding and may this tutorial work the same wonders for you as it did me.
Also I should state that the phone finally died at around 2Days 17hrs on battery. My goal for 3 straight days was cut short after a few 30 minute phone calls and other work I had to do on the phone.
If you have any questions. Feel free to post, or PM me. I'll be here =)

I thought it was the More Bars you have the more Data Kills Your Battery... but sprints 3G sucks .. some users only experience a .5kbs to 1.0 Mbs (if your lucky) ... that being said I think that's why your battery lasts longer. But then again I'm on Wifi so my battery has lasted all day ^_^ 15% left. Nfc on , Bluetooth off , screen at 50% brightness and heavy usage. Buuuut in your screen shot below your on 3G ... the 2 days.. was it always on Wifi?
- Google
What is your screen on time?
I don't use any "power-saving" apps, just AOKP Milestone 2 with Steve Garon's 1.14 kernel to run 50hrs with nearly 4hrs of screen time.
100/1100mhz, interactive governor, standard voltage, bln/bld on, wifi used whenever available. It doesn't help that my office is in a poor signal area - battery life would be much better if the signal reception bar stayed green all the time.

Screen time out is on 30 seconds. and Wifi was connected virutally through the entire time, exception was when I visited a friends house which is why in the screenshot it does not say it's connected, However it was still active.

Those are very nice stats, Question, On your battery log, What are the massive drops in battery from? low signal or just heavy use on your phone?
Also I believe I'm going to go back an retry my experiment with SmartassV2 governor and On Demand. because I recently read they are better than conservative.
By all means play around with these settings and if you report back something I can approve on I will be happy to update this post and give credit to whoever finds more tricks to improving the battery life even more =)

They're from heavy use, probably angry birds or web browsing. The poor signal usually results in much slower drain.

Not saying you're wrong, but based on past experience when I lived in an area where my phone was constantly losing and gaining signal or especially switching between Verizon (Roaming) and Sprint to find a signal, My phone would get very warm and it would cause massive battery drain.
Also in regards to the Sprints 3G speed.
Here in town where I live now, with the new KL2 radio
Edit:
I have attached screenshots of 3G speeds. It seems today when I ran the test the speeds aren't that special, I guess it all depends on network load.

I can get about 4-5 hrs on screen-on time a day with a full charge before it dies. I couldn't imagine spreading that amount of time over three days unless I was travelling again or something lol

Haha yeah sorry about that guys, That could have been helpful for me to post, but I actually just now realized you could view your screen on hours by clicking it. I feel about stupid now.
After I tweak some more settings and do this little experiment again I'll be sure to actually include that, Seeing as it would have been helpful LOL

How do you get your phone to idle so well? I can never get the battery stats to flatline like that. Could it be due to me having BLN turned on as the OP said that causes an idle bug?

There's a possibly you're running an app in the background that's preventing your phone from deep idling. Also try the battery saving app I mentioned in the post as well. It works wonders for some, and others don't notice difference. There's a lot of varying factors.
Have you wiped your battery stats and calibrated your battery with the method I mentioned above? Also you can check to see if your phone is deep idling by going into NSTools and clicking Idle stats.
If you see that your idle numbs are higher than your deep idle stats, Than yes, Something is preventing you're phone from doing so, and I would recommend disabling BLN and seeing if that fixes it.
It could be an issue with BLN and it may not be. My entire post is basically the steps and settings I've figured out and tweaked on my own to achieve maximum battery. I've read around and it seems some others have used BLN without any noticeable difference in battery at all. I guess it really just depends.
Also to the other post, The main reason I run my phone unclocked is basically, in use, I prefer the CPU to be at the lowest max speed possible, while remaining smooth, and I've noticed no lag at 800max, So therefor even when I'm using my phone it's still not going to be pulling as much power as if lets say I had it set to 1000 or 1100. Overclocking is great, Don't get me wrong, but unless you're doing something heavy like gaming or a sheet ton of crazy multitasking, I don't really think it's worth it. That's just my opinion though =)
So you're at home all this time? Then why go through all this trouble and handicapping of features and performance? Why not just plug it in?

How exactly am I handicapping? I had people asking me how I was getting my battery life and wanted me to post up details on it, so I decided I would. I run an underclocked phone because like I stated in my previous post, I don't see the point in running a overclocked phone unless you're going for benchmarks or doing a lot of heavy multitasking and then by all means, Take the 5 seconds to change your max CPU speed. If you're referring to me not running BLN, That's because for some, including me it keeps your phone from idling and will cause battery drain. It works fine for some, others it doesn't. I'm SURE it's a problem on my end, but until I get it worked out I'm just leaving it off for now.
I've been learning about rooting and modding since the Sprint HTC Hero days. I'm far from a professional and will be the first to admit I'm an amateur compared to you guys, I cannot develop, I cannot code. I'm simply wrote this guide as a reference point for people wanting to get good battery life, That's why I said tweak with the settings and have fun.
The main reason I'm so ecstatic about the battery life, is up until now I've barely been able to get a days normal use out of an android phone even running custom roms and all that good stuff. Now I can actually use my phone throughout the day, Throw it on my dresser at night, and wake up the next morning with still enough charge to use it again without having to worry about plugging it up every night.
Home or not, this info can prove to be very useful depending on an individual's circumstance. I work multiple jobs and when I get home, sometimes I'm so tired I don't even bother to fiddle with my phone's charging cable and just crash on my bed. I've gotten great battery life using similar tactics (went to bed with a 13% charge once, woke up with the thing still alive and kicking), so again, some may find this extremely helpful. Good work!

Thank you kind sir. I'm glad you were able to find this poorly formatted guide useful! =D
So I got my Nexus 4 on April. I was super happy with my phone and already knew how to root and install custom ROM's. So throughtout the last couple months I've installed custom ROM's and kernels. Well with several ROMS's and kernels my phone began to overheat a lot so my solution was to install another kernel to see if it worked. For example: the Franco kernel overheated my phone a lot and I asked myself if it was normal, I still don't know if it is. Since August, I've noticed I have horrible battery life. I have to charge my phone constantly frequently and can't use it a long time. So I flashed my phone to stock to see what happened with the battery and it stayed the same. So I don't know what to do. I'm not sure what damaged the battery but I think it might have been the overheating or all the ROM's and kernels i've installed. Please help!

its not overheating. if it overheats, the phone will shut itself down. what is your average cpu temp when the phones idle? battery temp when the phones idle? most likely its your own setup. apps that open in the background, and apps that sync. it can also be your signal, as lower quality signals drain battery fast. anyways, do you have many apps with notifications? do you have facebook installed? greenify is a good app to start with, for controlling your apps that is. the key to good battery life is controlling your apps, and setting up your phone to not waste battery.
I would highly recommend backing up all your data from your phone to your computer and flashing the google stock image through fastboot (there are youtube videos to walk you through that if you have never done it before). If you still have severe battery issues after that, then you can confidently say your battery is damaged.
It's normal for the phone to get hot.
Try other kernels, personally stock & Franco both have me terrible battery, HellsCore is giving me great battery though.

When the phone is idle, it gets to 31°C and on normal use (facebook, instgram) it gets to 38°C. I actually have good care of the battery. I always have Wifi, Bluetooth, NFC, GPS and Sync off. And I have Automatic Brightness. And I don't have much apps with notifications.

I actually used Faux123 and it gave me great battery life. But when I updated to PA 3.6 or 3.9, I installed it but it actually sent me to a weird yellow error screen when I tried to boot up the phone, so I had to flash stock to the phone to restore it. Which ROM that works with PA 3.99 would you recommend for battey life?
Like others have pointed out.. Your phone wasn't over heating. The N4 has a glass back. Glass is able to move heat very well pulling of from the inside and irradiating of outwards which will make it feel hot. My battery temp runs me between 80 and 110 degrees Fahrenheit.. (Or between 26 and 40.. Something C. ) never had an issue..
As for your poor battery life.. What Lind of screen on time are you getting? What a full charge last you with said screen on time.. Do you make or take a lot of phone calls?
It all comes down to usage .. Your screen and voice calls will obliterate battery. among other things.

those are normal temps, some might even be jealous of them. the ambient temp also plays a role in your phones temperatures.. the warmer its around you, the warmer your phone will be/get(or vice versa).
as someone pointed out, voice calls impact the battery greatly as well. calls take a lot of battery juice. also, facebook is a know app that like to misbehave, and take your battery, when not even using it.

Hi all,
I just come with this Screenshots to know your opinion on the consumption of my s5. Honestly Im jealous of those people getting 4,5hours of SOT in a full charge. I believe I can barely achieve 2h. My phone is rooted, de bloated with smart debloater and uses Greenify (which has not provided me a noticeable gain).
I've seen a very big drain just after plugging off the phone (like 5 or 6%) in two hours without using it. Also everything I unlock the phone the drain is very fast. So idle state seems no to be the cause
What are your thoughts? Thanks in advance.
By the way, while writing this post I've lost 5% of charge.

Need a new battery I think and with the battery you gotta keep it cool, don't charge you phone and use it when its under 20 ℅. And the hotter the battery gets the faster it will discharge and if your charging at the same time the CPU will work harder to charge the battery and do whatever you want to do with your phone making it a double whammy wearing out your battery much faster than normal. You not supposed to let our batteries to go below 20 %. Well you can but don't use it at the same time your charging.

Thank you very much for your information. Any suggestion about a new battery? I've seen this one.
I've just plugged off from 100% and I got a battery drain of 5% just by speaking 15 minutes (no hand-free). I think it's a very big battery drain for just a small talk. I think that confirm your hypothesis of the wasted battery.
Is there any way to know the real capacity of the battery I currently have? It is just to know how far it is from its original performance.
I've checked on Go Power Master app and it claims 2520 (at 90%) mah in my battery. Is this confident? If so, I shouldn't expect a big improvement buying a new battery. What about using other roms or making a factory reset?.

How old is your battery? Mah rating and the rate it discharges are different you can discharge 2600 mah batter in an hour or 3 days depending on use and environment and conditions. Like I said before the hotter your battery gets the faster the disharge go same with the cpu the hotter it gets the more power it demands from the battery. And if your battery get under 20% fast charging comes. Into play as well which is bad for the battery as well.
If your dropping off that fast I think is a defective battery or over clocked cpu settings. My s5 did he same till I bought a new battery I last 8-12 hours of heavy use now compared to 4 hours. With a new battery I suggest a higher capacity but same dimensions as the old one they can be expensive but a bigger battery will damage your phone over time.
I have a 5600mah battery now by 5he way.

Oh my power app tells me I have 2520 too but I really dont....heh
---------- Post added at 03:12 PM ---------- Previous post was at 02:46 PM ----------
Oh that battery looks OK I can't read the language lol just make sure its not refurbished or used and check out if u can refund it or not lol
My battery is from October 2015. It's the original one that came with the phone
Here is last report:
Despite performance is not the worst, do you think the difference with a new one is very big?
Back in my S3 Mini days I had to change the battery and the difference was huge for it. A year ago I replaced my S5's battery for the first time (I own my black beauty since february 2015) and I remember that I saw an improvement in battery life and in performance a bit as well.
A trick: take out your battery and put it on a flat surface (table or whatever) and try to spin it. If it spins freely, buy new one for sure.
I'd advise you to also update from KitKat to Marshmallow as that made my phone brand new but I see you're on 6.0.1 already so nevermind
I myself lose the first ~10% of my charge in one hour or even less...while not doing literally anything with my screen off. So yeah, maybe it's gonna be time for another replacement in a few months
By the way I tried Greenify today. The drain was far worse than when I didn't have it installed lol. Android Marshmallow is finally that one guy who's capable of handling himself alone without helpers like Greenify so try without it, it eats up your CPU anyway (as minimal as it can be, it still does).
With 3G always enabled I can get between 3 and 4 hours of screen on time (no games ofcourse) and around, idk, 10 hours total time until it hits below 10% and asks for some juice.
This^ was simply impossible with android 4.4.2 on the same phone so 6.0.1 really impressed me a lot as I had awful memories of Lollipop (that's why I didn't update for so long actually).
To sum up: try all the software ways of extending your battery life - with/without Greenify, uninstall/disable/optimise certain apps like Facebook and Spotify (says they slow down my phone), change ROMs, change kernels, change settings and if nothing works get a new battery.
PS: When Samsung go back on track and put a removable battery + all old features in a new flagship, I'm switching to that (S9, S10, SX, whatever xd). Newer phones got water cooling (~30 degrees while gaming, S5 gets 36-40C).
Thank you very much for your long answer. Honestly I don't trust too much battery savers. I've tried in the past many of them with no visible results. In fact greenify has never shown me any benefit. Notwithstanding, in this specific case, I've seen that hibernating "mi fit" (from xiaomi) I can appreciate a considerable improvement (5-10% of gain). I own a mi band and apart from keeping Bluetooth on (which seems not to be a big drainer) mi fit abuses of this connection. In fact "tools & mi band" seems to be more energy efficient with the connection to the mi band.
In any case I'll order a new one as it is not normal to have the drain for 100 to 90 being off and idle
I've changed old battery for a new one and I haven't seen any considerable improvement. After it, I've done a factory reset and a battery calibration (using the app on the store that requires root) and nothing... Any suggestion? I have the feeling that new battery is OK but somehow my phone is unable to take advantage of its performance...

Right now I have DreamUX V2 A7 (2017). I flashed one week ago hoping to remove this strange battery behavior. But it remains. Do you think reflashing stock firmware will fix it? I'll check instructions before going ahead. Thanks to both!

If it gets fixed after firmware reinstall then it's a software bug. If it gets fixed after changing the battery then it's a hardware bug. If it doesn't get fixed after trying both things then it's black magic :s
Also try to clear dalvik-cache and cache and do factory reset before and after flashing.

OK I'll go ahead with this. Good guide to reflash stock rom?
I'll do several factory resets to see if it helps, but I start to think that it's black magic

Sorry for the delay in replaying but I've made several attempts with not specially good results.
Now I'm getting 24 hours battery with 2h SOC for WhatsApp and browsing. Furthermore, I use Bluetooth for the miband.
The battery drop from 100 to 90 still remains. Maybe it's smoother but significant.
I've changed battery, changed roms (several times wiping everything). I've tried battery calibration app from rooted devices. I've tried the calibration procedure for non root devices (here I think I've obtained a little bit of improvement) but in general I have the feeling my phone is not detecting well the capacity of the battery (either new or old). Any tip? Advice?. Could it be the charging circuit? Can it be fixed? Should I keep doing calibrations more often to see if I grasp more capacity little by little?
Thanks for your time and help
