[Q] i9505 Overheating @ idle - Galaxy S 4 Q&A, Help & Troubleshooting

I noticed that my S4 i9505 was getting hot despite what I was doing, playing heavy games like RR3, or just seeing some stuff on the gallery, and my battery is lasting around 10h...
So I made a test, put the screen timeout to 10 mins, and let it on the homescreen (with black background and no widgets, I have absolutely no widget on any homescreen), the battery drained very quick, and the screen was hot like hell
I forced to close all apps, cleaned RAM, and began the test again, same thing, battery draining quick, and screen very hot...
So I tried turning off wifi+GPS+mobile data, and made the test again, the battery didn't lose even 1%, and the screen was room temperature...
Now, why is it getting so hot and draining battery with wifi+GPS+mobile data even if I don't have any widget, and I always chose APPs like facebook to keep me always offline and never notify anithing?
This phone was very expensive, and I use Gotya to protect it from thieves, but I need to keep wifi+GPS+mobile data ON with I want this program to work, so I don't want to need to turn everything off and take the risk of being robbed and now getting it back, but also I just wanted to the battery last long enough so I don't need to charge more than at night while I sleep....

These are the options I use daily:

Even with power saving ON on two places, it rarelly lasts enough to not charge it before I go to bed
And this is my homescreen:

Using Wifi+GPS+Mobile Data, it will spend ~4% every 10 minutes... but when I turn them off, it'll spend ~1% every HOUR!

That's not too unusual. What do you expect? Using Wifi+GPS+Mobile Data does consume battery rather quickly on any device, particularly when the screen is on and driving a 5" Full HD screen.
If the Wifi+GPS+Mobile Data have weak signals, the battery will be consumed even more quickly than normal as the respective radio strains to connect to the weak signal. Even when the phone is completely off your phone, the battery will lose power, though at a slower rate.
The art and science of power management is about knowing what you want and prioritizing your needs based on realistic performance expectations. Almost nobody needs to run Wifi+GPS+Mobile Data at the same time, so ask yourself what's the thing you are doing and then prioritize your power expenditure based on those needs.
In my case, I don't use autosync. I sync manually every hour or so if needed, or less if not, and same for location services: Off until I need them. I toggle my data off when not using it, use Wifi over mobile data because it tends to be stronger signal and use less battery, keep my brightness at manually set reasonable levels, and I can easily get two days out of a charge, even with 4-5 hours of screen-on time, which includes gaming, surfing, calls, texts, voicemail, etc.
I'm not dissatisfied with the battery life, but I am dissatisfied with a few other things on the S4. It's not a perfect device, but overall, it's good, and I'm not even running a stock ROM, which is most typically said to give even better battery life overall.
Every Wiz-bang "feature" of Touchwiz comes at a price. There's no free lunch, my friend. Turn off what you don't need, or be prepared to pay the price for it.

About the screen, as I said, in 10 minutes with W+G+M ON (Don't want to keep repeting every time) it spends +-4% with screen turned on (and it even gets HOT!)
with W+G+M OFF it spends 1% or less with the screen turned on (at least on my homescreen that is very dark) (and it keeps on room temperature)
I just expected that it didn't drained the battery so furiously, since I have no widgets to keep getting updates from internet, Sync is turned off, etc...

I live in a warm, tropical climate, and at times, during gaming or in poor signal areas, my S4 will get a bit warm, but nothing unusual, and again, when you have the radios turned on, they are going to heat the device up and consume the battery, and the hotter it gets, the worse the power loss is. It's just a fact. There are inescapable Laws of Physics at play here. There's no way around them at present.
The radios use a lot of power, and much more so when they are all on at once (as you described) and straining to connect in a poor signal area.

By the way you're talking to me, I assume you think I'm a dumbass, it's obvious that the hotter it's getting it's because it's speding more energy, that's why I'm putting enphasis on the fact it's getting HOT, because I'm with absolutely no APP open, even made a "clear RAM" to close everything, and still it's getting HOT of how much energy it's spending even in IDLE
I have a nokia N8, and if I let it with screen on, on IDLE, wifi ON, 3G on, it won't get hot as my S4 is getting from the draining of the battery

That's not what I think. I don't experience what you do, so I can only guess that it's something related to a) Tochwiz and/or your software cong or b) something hardware related to your device.
Have you thought about flashing CM to test it? I'd be curious to see if it continues.
FWIW, I'd love a Nokia-based Android device. Their hardware is amazing.

Go into Settings > More > Developer Options > Show CPU Usage. It should indicate which process is using a lot of CPU and heating up your device.

That gotya protection app should be working overtime on all radios keeping it awake and running all the time ... may be something with it's settings or you should find another one to do the job ... generally if you have some apps syncing and an open data connection halves your battery life and even more if that is mobile data but still your case is certainly abnormal and i think it has to do with the particular app you mentioned using ...
uninstall it and test how battery hold with data connections and gps on ...

The power consumption is huge

Yesterday, I was using the Google navigation on 3G network with the phone connected to a 500mA car charger. After 1hr, the battery dropped 20%...Anyone knows if a 1000mA car is enough??
Tonight, I was watching a Youtube HD video on 4G network (2/3 bars on 4G) with the phone connected to a 1000mA USB wall charger. After 10min, the battery dropped 2%...Well, even 1000mA cannot compensate the consumption of the battery.
The power consumption of this phone is ridiculous. Something must be wrong with the system/circuit design.
NOTE: I'm not complaining the battery but the power consumption of this phone. The charging cannot compensate the usage of the power. Think about a laptop. It's even more powerful, but you can use it freely without any concern about the battery as long as you plug it in an ac adapter. Why can't Epic 4G do this?
man i been seeing the same problems i was listen to the sprint radio while hooked up to the charge and would see it stay at the same percent for about a hr before it went up 1%. this battery issues is making me hate the phone right now and i cant find any rapid charge programs or settings for this yet. cant wait for some custom rom to come out that hopes to fix some of these issues
yup 4g is a battery hog which is why people are complaining about battery life,I suggest you turn it off, it's just not worth it IMO, which too bad cause we're paying extra afterall.

I saw a post this morning. The 3G even consumes more battery on Epic 4G during browsing. so we can expect even worse under 3G.
I'm on my third Epic and they have all had battery drain issues. Battery manufacture dates ranged from July to mid August. Right now actually, I'm streaming some radio over 3g and have an AIM client running in the background and the batter is slowly draining while plugged into the charger included in the box.
I have tried a factory reset just to be sure any apps I installed weren't affecting anything and still no dice. Even with running navigation in the car while plugged into a usb charger the battery will drain about 1% every 5 minutes or so. I'm probably returning the phone for good in a few days
This is with 4G disabled, using SwitchPro widget to enable 3G. I also have background updates disabled(under accounts/sync), I manually do them periodically.

That shoul be more than enough. I use a Motorola-branded 850mA microUSB car charger (quite cheap on Amazon). On a recent day-long driving trip, it was sufficient to maintain the battery level while streaming audio over 3G and simultaneously running GPS tracking. I don't think a 500mA unit would have handled the load, however.
I'm really starting to think this phone is an epic fail. I get from 1.5 hours to 2 hours of use from a full charge! Thats with everything off, 4G, wifi, bluetooth, GPS. The sprint store manager wouldn't exchange my phone because he said their is nothing wrong with it. If it takes 6 hours to charge and then I get 2 hours of use, this phone is worthless to me!

Yeah that doesn't sound right. I think most people would have a hard time making it last only 2 hours. Maybe gaming while running WiFi tether.
Keep in mind with CDMA, the lower the signal to the tower, the more power it takes to keep the connection active. For GSM this is less of an issue. How is the signal where you live?
An interesting side note. I plugged in my charger for my Bluetooth which is only 180ma and it went from 70% to "Fully Charged" in 10 seconds. When I unplugged the charger it went back to 70%. It really didn't like that low power feed.
Sorry if it came out orange. I used screenshot the app and that's what i got. Anywho, its a perfect combo what I've done. See the up time, nearly 15 hours up time. I only lost 35% of life during the time too as you can see how full the batt is.
Remedies: Autokiller set to extreme. ATK: Set to aggressive, with auto kill set to when screen is off. Interval every hour. Cachemate: all settings lit up, so it clears about 12-14 MB every hour or 1-2 every manual clear. Set CPU: Conservative 1000/100 with set to boot. Notice, set CPU resets itself every reboot for now, just make sure your good.
Then you should be good as I have for TWO days on one charge nearly 24 hrs ago.

I would love to see more info/screenshots on this. The one SS you included somehow ended up thumbnail sized only. 2 days is nuts, anything over 24h would be.
hey guys
I've been really happy with the battery life on my epic - I get about 12-14 hours with on-off use, 4G off. My battery is sitting at about 35% after playing a bunch of games for about 3 hours in between classes and it has been running off battery for about 8 hours, browsing the web, sending texts and downloading apps on both 3g and wifi.
I'm using Advanced Task Killer and its set to kill aggressively every half hour - it kills all apps except Juice Defender, itself and LauncherPro.
I'm running LauncherPro - if that matters - doubtful, but I didn't like touchwiz. And I'm running JuiceDefender on default settings. Basically it kills the 3G radio when screen is off unless its transferring > then 15kbs of data. The normal radio remains on for calls/texts.

What is the EVO fix? I'd love to try some extra tips.
My two cents - a typical day puts me at home and at work for the majority of the day and night, which both have wi-fi. I've turned off "look for open networks", "never allow wi-fi to sleep" and I leave wi-fi on. After a full night of charge I took the phone off of the charger at 11am on Saturnday and it finally turned off Sunday at 8pm - 33 hours is pretty darn good, almost two days. However yesterday I took the phone off the charger after leaving work at 6:30pm (so no wi-fi, just 3G) and in just an hour with watching a 15 minute long normal quality YouTube video, a few texts and a short phone call I was down TWENTY PERCENT. What the heck.
Over wi-fi, like I said, I'm good - great battery life since I'm not waking up the 3G radio to do anything. But when I get out of those wi-fi areas that's when my battery starts to drop. Anandtech is getting similar results with awful 3G battery:
http://www.anandtech.com/show/3891/samsung-epic-4g-review-the-fastest-android-phone/8
Something is wrong with the 3G radio, and I hope Sprint & Samsung seriously do something about it.
You guys are all failing to look at "Cell standby" details.
Time without signal on this phone - no matter WHAT coverage area you're in - is ALWAYS > 50%. This is bull**** and a Samsung software issue. Take a look for yourself.

I never had a problem with but I've been reading many having a problem with "Cel Standby" going out of control. Mine it at 17%. Highest I have saw it was in the upper 30's range after a full day (14hr)
Just an update on my usage from Pg.1:

I am not seeing this issue. Never seen it above 3%. Besides most of the battery is going to the screen it seems. I am actually wondering if it reporting the usage correctly. If the screen was really take that much of the power, it should be lasting a lot longer.
People getting great battery life are reporting they are using task killers and data connection blockers. That isn't even where they majority of the power goes. The system tells us it is going to the screen. Not the tasks or data connections. It seems counter-intuitive.

Turn airplane mode on then off. (settings -> Wireless & Networks)
This will solve the problem until the next time you reboot. You must do this after every reboot.
I'm working on a more scientific breakdown of power consumption. But here are some brief findings.
The highest power consumer is the display. Even on the lowest brightness setting it consumes more power than a normal LCD (I'm comparing it to my Evo). If the display is only showing a black background it is lower power, but then again if all it is showing is noting, it may as well not be on at all. If you actually want to display something on the screen, it consumes power like it's going out of style. So much for Super AMOLED being a power saver (total and completely false.)
The next highest power consumer is the 3G radio. Under similar circumstances (similar signal strength) the 3G radio is consuming more power than the 4G and Wifi radios combined. Wifi seems to consume the least, followed by 4G then 3G. This is crazy and if not fixed might be unacceptable.
Next is background apps, most specifically anything that uses the network (email syncing, social networking and location reporting services like latitude) being the worst. The sync settings on the Epic are not as robust as the Evo and I've struggled to gain control of gmail without just setting it to manual only. Do not use latitude and although some will speak out against task killers, having one to keep "maps" at bay is worth it alone.
Then there are more obvious things like live wallpaper. Or specifically anything using the CPU / GPU and GPS.
More to come, but right now, something must be done about the 3G radio and GPS or this phone could live up to the moniker of Epic fail. I really hope Sprint and Samsung are doing something because otherwise if the phone worked as it could, it would be awesome.

[Q] Battery life makes me cry

(I'll preface this by saying that I am well aware there have been a million threads about this, I'm sure, and I'm even more sure that there will be a million more. And I have searched, and searched, and searched some more, and I still feel the need to post this question. Flame me if you want. I'll use the flames to heat up some tea, or something.)
I bought my phone last Thursday, it got lit with service Friday. I went over the weekend and into Sunday with stock ROM/kernel, and decided to mix things up by rooting my phone and using the MixUp kernel to see if I could get better battery life.. and it didn't work too well. I mean, life went up a bit, but not noticeably so (maybe twenty or thirty minutes?)
After that, I flashed Syndicate, which had Xtreme Kernel. I calibrated the battery as instructed inside of Clockwork and went with it for Tuesday.. took it off the charger at 8:00 and it died around 4:00. Kept the same kernel and flashed Epic Experience and the attached JuicePlotter shot is where I am at right now.
My usage today has been light browsing and that's basically it. I've got the processor underclocked to 600 with SetCPU, and JuiceDefender and Superpower have been preventing any data from going on when my screen is off, and for the last two hours I've been listening to MP3s using the in-built music player.
This makes me cry considering there are people on here saying they're able to get much more life out of their battery, even with BT and WiFi etc. I'm aware that each phone is different and all that, but still.
All that said, is there a problem with my phone/battery, is this par for the course with the Epic, or should I just stop whining?
Thanks in advance for any help/insight.
A couple of things...get a task killer app so that you can kill the drm process which eats up a ton of battery, calibraing your battery takes 2 or 3 times going from full charge to zero and also, since its a new phone it takes charging to full and letting it get down to complete zero a few times before you will see better battery life no matter what else you do
Edit: oh and also definitely do the airplane mode toggle as well

Also, for each new Kernel you flash, you have to calibrate the battery.
Charge it to full, boot off, boot up in Clockwork, go to Advanced and Clear Battery stats. Reboot the phone, use it until it runs dead and shuts off, than plug it back in and charge it to full with the phone on.
Every time you flash a new kernel, you have to do that process so the battery calibrates to that certain kernel.
Also, try Baked Snack, it gets the best battery life for 2.1 ROMs.
http://www.bakedsnackshack.com/source/
Download Bakedsnack1.6 and Step 2.
Make a backup.
Wipe data/cache
Install 1.6
Boot the phone up
Reboot into clockwork
Install Step 2
Boot the phone up.
I have to have a car charger if I go anywhere. This phone dies so fast with normal usage. Do anything crazy like turn features on, surf the web, or increase brightness, and I am lucky to get 2 hours. I have multiple batteries, both have the same result.

2 Hours..? Whaaaaa? Lol.
When I calibrate my battery, I turn EVERYTHING on, screen brightness all the way up, Pandora running, every widget I can fit on my screens set to update at their quickest setting, screen set to 30min (Though I never let it shut off). Bluetooth, GPS, 4G running (I don't have 4G here, so it just keeps searching, which drains it more than if it was connected). And running the Maps Live wall paper to use GPS.
When I do all that, I can't get it to even die under 4 hours.
Hopefully you were exaggerating with saying 2 hours lol.
Thank you guys for replying!
Sh0wNuF: I killed the DRM service today and used ATK to kill errant processes throughout the day today to no avail. I also used the airplane mode toggle to try to limit my time without a signal.
SemiGamer: Thank you! I did do the clockwork step as I said in my first post, but I will try to install BakedSnack and get back to you guys as to the battery life.
From the looks of that juiceplotter graph, your data is constantly on and destroying your battery. What is the point of having juicedefender if the data is constantly on?
If you set up the phone properly, and there are a MILLION threads on this which state a MILLION times to disable DRM and toggle airplane mode as a mere baseline beginning, you should lose at most 1% an hour when the phone is idle without a data connection and the screen off.
Now it looks like you probably have the data on constantly with emails rolling in, facebook auto updating every 5 minutes, weather checking every half hour and other things that are just destroying your battery life. If you need your phone to do all that nonsense, then you will be crying for the rest of the time you have it.

Thank you for your reply, but as I said in my first post, I was using both JuiceDefender and Superpower to make sure data was off in the background, and as I said in my most recent post, I did disable the OmaDrm service as well as enable/disable Airplane Mode to lower my TWS.

Thats fine, but your data aint off. Look at that graph you posted. Every little blip is either data being accessed or the screen turning on. The line should be smooth if there is no data and no screen on.
So there are two options, either you are constantly using the phone and its the screen killing the battery, or you have juicedefender set up all wrong and its the data killing the battery.
If I remember correctly, any spike below the line is data, either wifi or 3g and any spike above the line is the screen turned on. So from the looks of it your data is literally never turning off and you are checking the phone and turning the screen on and off pretty frequently.
What are your settings in juicedefender?

I have almost identical batter results as you. I do use the phone fairly often to send messages but the screen brightness is all the way down and I use set cpu on the froyo beta leak. I reset battery stats and also (perhaps you could look into this too) checked spare parts for any rogue programs. Does yours say the screen takes up most of your battery even if you barely use it?

I would up the Schedule to less often and turn off the traffic toggle. Also, I wouldn't doubt that your phone is never going to sleep. If you have spare parts check the Battery History. If you listen to music with the phone, the service started by the music player, CorePlayerService, keeps the phone awake constantly for me. I ended up making a simple kill music widget using tasker to fix this issue.
I bought a wildly overpriced Samsung stand/battery charger from Amazon. My wife & I each start the day with a charged Epic and a spare battery. No worries

Not the biggest fan of the aesthetics of the ROM.. but I'll live.

When you say much better battery life exactly how much? My battery dropped 20% today while not being used and Display was still at 60% (I turned the alarm off twice). I'm running the Quantum ROM which could have something to do with it but the battery is horrible for me. I can't get more than 8 hours and that's if i barely use it. I have spare parts and no apps are partially waking it. Just Wifi and sync. No GPS, brightness all the way down. The main thing that bothers me is that display is always #1 even if i don't use the phone at all. Any thoughts?
I've ran both Quantum and Viper Froyo roms and aside from making my phone hot enough to fry eggs, the battery life was not good.
As far as battery life goes, I'll start with the obvious stuff.
1. Turn off GPS, Bluetooth and 4G. 4G is a complete power whore.
2. As for wifi, turn it off unless you are in a bad coverage area for cell data. If you are connect to wifi and set Spare Parts to never let wifi sleep.
3. For DRM there are 3 files you need to remove that will prevent it from running / reinstalling and they are DrmProvider.apk, DrmUA.apk, and SisoDrmProvider.apk.
4. Toggle airplane mode every single time you reboot without fail.
For a true test of whether your phone simply needs to be returned as "defective" you should wipe the device, dont setup a google account and let it run for a day after executing steps 1-4 above. It would be best to an apk for Spare Parts and SDX Stock App Remover on your microSD that could be installed using My Files. If you still have problems take the phone back to sprint (after restoring it to factory of course) and tell them it is defective.

Here's a JuicePlotter graph from today for comparison from my original one yesterday.
I still wonder if it wasn't going to sleep because of PowerAMP and I didn't underclock today like I did yesterday.
There are a few other physical issues with my phone (slider seems a bit loose compared to my other phones: if I swipe with slider closed with a bit more pressure than usual, I can feel the screen move up and down; screen seems to slightly come up a bit when phone's tilted a bit, taps make you feel the screen go back down) that also made me want to consider exchanging it on top of the battery issue but if I'm getting good battery life I don't think I'll mess with what works, unless anything gets worse.

[Q] How to preserve the battery life in a location with very poor signal

First to clarify my question: I'm not asking how to prevent the daily battery drain in a poor-signal area. It definitely happens unless the phone is switched to airplane mode. My question is how to avoid the shortening of the battery life in the long run if the phone has to be used in such condition.
My workplace is basically a signal black hole to any carrier. With T-mobile I got no service for most of the time but I can occasionally send/receive text messages/emails say every 15 minutes with flimsy connection. There is absolute no way to make a phone call, so I usually walk outside when needed. I don't have WiFi neither so I prefer to keep the phone on to stay on the grid. However my concern is doing so will shorten the battery life eventually due to the constant power draining and recharging, so I come up with some ways for such condition. Please suggest which you think will do the least harm to battery and allow me to receive email and text.
1. Use it normally. It usually consumes 60% of the battery just sitting on my desk throughout the day. I can actually live with it be cause the battery is large enough for me to waste this way. But it harms the battery life without a doubt.
2. Use it with a charger plugged on my desk for most of the time, so it will supply the power for signal searching. Usually if you keep a battery at full charge all the time, it dies soon due to "slacking." My laptop has this problem and its battery basically serves as a UPS now. I have less concern for a phone because it will still be recharged daily.
3. Use an NFC tag to tell the phone it's in the office, and then use some software to prevent the draining like Tasker/Juice Defender. That makes most sense but I haven't have figure out the profiles. I've used Tasker before (thought it's too complicated) and NFC is totally new to me. I would like to take some suggestions if you have done something similar.
Thanks!

Isn't the issue with batteries related to cycles? I'm not sure it matters that you end up with 40% of battery at the end of the day vs 15% when you charge it up. A cycle is a cycle, more or less I think.
If you don't believe the first point, I also don't think that research really shows that leaving a lithium ion battery plugged in "all" the time has major detrimental effects, and even if it did you would still be using the battery for a good deal of the day, at least the time you're not at work right?
I feel like you might be a little too worried about it.

About the charging cycle, I read something here: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries. Basically it shows deep charging cycles has more detrimental effects on the battery capacity. My point was if the battery is cycled deeply everyday, it is under much more stress compared to those working with good signals.
Maybe I worry too much but I feel really bad just to see my phone sitting there wasting a lot of battery.
I have had the same problem with you as my office is underground.
From my experience, it's best to turn off data. You can turn off the radio all together, but I guess you still want to have signal where you can.
This can be automated by Taker (haven't used) or Juice Defender. I don't know if Juice Defender Free can do this (it should), but Juice Defender Ultimate have an option to turn off wifi and data when the screen is off.
Having the charger next to your desk is also a viable option. But rather than plugging it all the time, you should charge when it is needed.
Edit: as discussed elsewhere, you should not try to do full charges (0-100%) as this would not work out well for you at office as well as it it will shorten battery life.
Edit 2: Juice Defender Ultimate
=> Enable Advance profile (Status Tab)
=> Go to Control Tab
=> Enable Mobile Data and Wifi control (first and third option)

Can you try only charging your phone at work? From the options you've listed,leaving it plugged in seems like the best option at work seems like the best option. Assuming you currently only charge your phone once a day, it shouldn't make much difference to switch the charging time to during the work day.This way your peak energy usage will fall on a time when you have unlimited power available and you should have enough battery to go home and come back.
build.prop tweak
There is a build.prop tweak but I can't guarantee that it works.
You can try it out and tell us about it :fingers-crossed:

#improve battery under no signal
ro.mot.eri.losalert.delay=1000
The number value is how often to re-connect to the tower. A phone in a poor connection area will
attempt to reconnect all the time, draining the battery. It's in milliseconds so 1000 = 1sec. I wouldn't
exceed 2sec but you already knew you are on your own with this one.
I have the exact problem at work.
My question is if I connect the phone to the charger at work, will the phone runs on the juice from the charger or from the battery? If it runs on the juice from the charger (like laptops), that should have minimum effect to the battery. If it uses the battery and the charger just charges the battery then the battery life will be cut in half (2 charge per day instead of 1 charge per day).
I have terrible signal at work and my Inspire has a small battery. My phone is in power save by lunch. I charge mine during lunch every day and leave it on the charger at night. I generally will not plug it in if I can't charge it all the way up. My original battery is now 18 months old and works as well as it did new. Other Inspire/DHD users have had to replace batteries in less than 12 months, so I don't think my charging cycle variations have harmed it too much.
It only has to last until after the holidays when I can order my N4. Even if I had to try to push it to 2 years, I think I wouldn't worry too much.
Also, by the time it is not under warranty, the batteries will be cheap and will always be easier to change than an iPhone.
Sent using the power of the dark side.
Thanks everyone. Based on the discussion I think I will just use it normally and charge whenever needed. The phone should be my slave not the other way around. I'm not planning to root it, at least not now, so I won't change the build.prop.
I did tried Juice Defender yesterday. It slowed down the battery drain but not very impressively, because it only turns off the data not the entire cellular radio. I installed the app during lunch so you can see the difference from the middle of the day. Google+ was a real ***** because it tried to upload my camera photos with such connection... I turned it off too so it also helped.
"Android OS" should not be this active.
It's possible that you have some background process draining the battery. Try disabling as many services as you can.
If you have Wifi at work try turning it ON. If not then turn your Mobile Data OFF like KyraOfFire suggested.
I get weak signal at my work as well. Thankfully, we have WiFi, so I usually force my phone to use 2g then connect to WiFi. :good:

[Q] Unrooted Note 3 - Battery Drain, Most Tips didn't work.

Hi Guys,
Firstly, I know there are several threads with different tips and suggestions but most of them didn't work for me.
Recently (since more than a week) , I have noticed strange drain in battery and getting hot pretty quickly. It has kitkat and I didn't get time to use it properly in the beginning. After reading different threads and forums here's what I did:
- Let it drain completely, shut off, took out battery for a couple of hrs and then charged without switching on. x2
- Rebooted after charging
- Uninstalled some apps I thought might be problematic
- Factory Reset (such a pain!)
- When attached to Kies, it prompted for Firmware update N9005XXUENC2 followed by another factory reset and hard reset.
- Cleared cache by going into recovery mode.
- Rebooting after charging
But seems like none of it made much difference, my routine use
- couple of hours on wifi
- no heavy games, only temple run, subway surf etc.
- no streaming
- no lengthy calls, not a lot of messaging
- 1, 2 hrs of music
- Syncing off, gps off, blue tooth off, Wifi mostly off, power saving on, brightness on auto, no 3g/4g data, almost no photos and video capturing, sensors, motions off except smart stay
I don't want to root the phone because of my busy schedule, with some difficulty I was able install WLD on it which resets after Rebooting. Point is, I am not a heavy user and this being a "beast" isn't quite unleashing the beasty-battery-life. I do get more than a day but that is when it's in deep sleep for 20hrs or more. I took some screenshots after reseting, updating firmware. It's past 3 battery cycles now, I will attach the latest one's to not clutter it up. I like this phone, but this battery is just not good enough. So, please helpful answers that don't require rooting.
Thank you for reading and Good day!
Is the battery drain consistant or does it happen at certain times (at home, at work, etc.)? If you are in an area where the signal changes frequently that will drain the battery because the radio is using power to maintain a connection. With wifi scanning for google services even when turned off setting make sure it is off if you dont need it. How do you charge the phone? If possible always use the charger that came with the phone, charging from a usb port from a computer is not as strong and can affect the memory of the battery and do not wait till almost dead to charge. It works best to recharge when between 35% and 45%. Look at your background services and see if anything out of the ordinary is running. And it could be possible the battery is defective and you might want to have it tested. I use my Note3 lightly and get 24 to 25 hours over two to three days (turning off at bedtime). This may not help any but this is what I have learned from others with similar situations. Good luck!

Hey MPDnnrd,
Thank you for your response.
It is sort of consistent, did you see the screen is just at 18% and the Android system at 30%? I think this is where the core problem lies - just don't know what and how to fix it.
- Signal Strength: Pretty good, hasn't been a problem
- I normally keep the wifi-scanning off and Now I turned off the location services to see the impact but then I think what's the point of premium device if you have to switch off everything.
- I prefer to use the factory-charger over usb-charging and I read it on several threads to let it completely die and then recharge, guess that didn't help.
- Background services - I don't think so, I kill all the apps as soon as I stop using them, use Greenify to hibernate other, switched off all auto-updates and notifications. Even on Playstore, I switched off the auto-updates and notifications.
- Defective Battery: Now this one, I haven't tested yet not sure how to - the phone's just 2 months old so shouldn't it be good enough?
I know they are not very helpful, but still thank you very much. :good:

I'm sorry to have to say this but I think you got a pretty normal battery drain by looking on your screens. You played almost one hour subway surf(which drains the battery pretty quick) and I guess the other hours where internet (also known to drain battery) or calls/messages. On a not rooted device with stock kernel that seems like normal battery usage to me!!!
However if you like to check these maybe u get a couple of percentages(not that much though I guess):
-Power saving mode in notification drawer makes your cpu clock go down (not sure u got it on not rooted device sry)
-check turn of pen detection in s pen settings
-put the brightness on auto or put it down manually
-if you can change the theme color in apps do so(make it black)
-check the svoice settings so it doesn't listen to your voice
-if you don't care how your phone looks buy a zerolemon battery(I think it makes your phone too big but that's preference)
-don't use a bright background keep it dark colors and no live wallpaper as well
Maybe that helps a little.
I don't see any drain either. Almost 6 hours screen on during 24 hours is excellent, additional 1.5 hour awake time for other services. Excellent battery life.
Settings - General - Applications - disable unnecessary apps
In Google Settings, opt-out interest-based ads and disable location access.
Thank you for your reponses guys - thing is it actually had much better battery life. What I don't understand is the fact that Screen % used to be on top and android os and system was below it but now it has been on top.
I have tweaked quite a few things already that 4aces suggested and the S-voice thing seems new, I'll look at it. Today it didn't even last a full day whereas I know people who even after heavy usage get easily more than a day - mine one, I don't use it this much. The Zerolemon thing is beast but then the phone is a freakin block lol so heavy and big, good travel etc. where you can't charge your phone and has a rugged case.
But there's a change that I saw today, Android System is now below the screen so I am not sure what made it do that but may the next time I charge it gets better and so on. I'll keep you guys posted after charging it today, I'll monitor what I do.
Blondasisko - I wouldn't really call it excellent, but it's sort of getting better than it was in the first 2 cycles. But how do I reduce additional awake time for other services? Moreover, you might've noticed I got till 1% to get this much time like really stretched it to get there.
Someguyfromhell - Already done, locations were off starting today.
Can anyone else comment on their daily routine of usage and the battery drainage ratio?
If I get 12 hours and 4hrs screen time I'm happy. I don't even play any games. Have a lot of accounts syncing lot of Internet and a bit on the calls, gps. I get on average 14 -16 hours
I have brightness on high. If you put it on auto it makes a big difference.

I guess I should feel lucky, I have ZERO syncing, auto brightness, no live wallpapers or gimmicky stuff on, no gps, hardly 10mins or so on phone calls and prolly 30-60mins on messaging a day.
@all others - and the Android System is back on top - what could be the possible reasons for it?
I think its because of such minimal use that the system goes on top. The system still had to operate so when you have hardly used the phone then the system will go on top. Though with that usage you've stated you should get nearer 2 days really

You're right probably, this is what I'd like to know as to what is running in the background that drains more battery? Exactly, at-least 1.5 days is what I should get with this usage. May be I should buy a new battery and see how it works.

Unrooted 6P on Nougat Hot in Pocket, Cool on Desk (Project Fi)

Hi, I've had my Nexus 6P since June now and I've been noticing some issues with battery life and Android N. The weird thing is, the battery is only having troubles when the phone is in my pocket. If I leave my phone on my desk the battery drains very slowly, but while in my pocket the phone gets hot and the battery drains much quicker (e.g. a short 10 minute run to chipotle for lunch left me with 5% lower battery. My phone didn't leave my pocket the entire time).
I'm using Project Fi for service and am in Manhattan, so service isn't an issue. I use the phone with backlight settings at 50% and I don't use the screen more than 30 minutes a day on average. I have location services disabled, I'm on the most recent Android N preview, I use WiFi at work and at home. I have a Pebble Time smartwatch that is connected via Bluetooth to my phone all hours of the day. My phone is Unrooted and has no custom bootloader. I don't have any apps that contribute significantly to my battery drain.
I suspect that my battery issues are from the new and 'improved' Doze feature on Android N.
I don't have a battery breakdown handy (cause I stupidly plugged it in before screenshotting) but the top stat on my battery drain is Android System, with CPU total over 1.5 hours in a given day and Keep awake over 45 minutes at least.
If anyone has experienced similar behavior or might have a clue as to why my battery is dying and how to fix it, please let me know!
Thanks!
- Eric
I turned off the 'ambient display' option in Settings/Display almost immediately upon getting the phone (which I've had for 3 days now!) I found that it would wake the screen and turn off a bunch of times if I was just carrying the phone and not actually interacting with it. I can see that being a big battery drain just for the screen time.
Good luck!
I don't have a solution, but my Nexus 6P has a similar symptom: It gets hot when it's in my pocket at work.
Based on the wifi wakelocks I've seen in Wakelock Detector, I suspect it's trying too hard to stay connected to the wireless network. We have a few access points at work, and it's possible my phone is switching back and forth between the two closest access points. It's also possible that the wifi signal isn't strong enough, so the phone boosts power to the wifi radio.
I'm on Project Fi, and I know the T-Mobile and Sprint signals are both weak at work. I don't know how much energy the phone wastes trying to keep itself registered on the mobile network, but I imagine that could also be related. Even though Project Fi will successfully use wifi to send and receive messages and phone calls, I'm pretty sure it still keeps trying to get a better connection to the mobile network (like every other phone).
It's difficult to judge whether the phone actually does something to cause a higher temperature while it's in my pocket, or if it just dissipates heat better on my desk. My pants are definitely too tight, so I'm sure that doesn't help.

Hey, thanks for the tip about ambient display. I turned it off and I'll let you know how it goes
This is pretty simple. Phones rely on airflow to remain cool because they have no active cooling. A phone on a desk has airflow. A phone in a pocket doesn't. No airflow means hotter phone. A hot battery drains much faster than a cool battery. That's all it comes down to.

Totally not what's going on. When in my pocket, the processor gets really hot, the rest of the phone warms up from my leg heat, but there is a hot-to-the-touch feeling to the top of the screen near the CPU which indicates higher clock speeds on the CPU while supposedly 'idle' in my pocket.

Hey, thanks for the reply. The "Android System" app is currently listed as using 19% of my battery followed by android OS then Chrome.
Android System has a CPU Total of 1 Hr, 30 Minutes, 34 minutes of keep awake and 800 mAh computer power use.
My screen has been on for 13 minutes and is computed as using 42 mAh.
This is all only 6 hours after taking my phone off the charger.
Thanks.

There's a lot of processes covered under Android System. I would start with location services by switching them to off for at least a day.

Location services have been off since I got the phone. I only turn them on when needed for maps.
