Battery issues... what battery issues?

So as I read through the forum I see many people say that the Epic 4G has some pretty bad battery issues. Well, I've had a few Android phones and by far the Epic has the best battery life I have ever seen yet. If you guys have any questions about my settings or anything, feel free to ask me.
Here's a screen shot of my battery life from the other day... it was pretty "Epic".

how much time was with phone actually in use
impressive

I used it with some pretty heavy use. I was texting all day and playing around with some apps as well. I didn't charge it overnight to see how it would hold up overnight and it held up well.
I am using a custom ROM that I have actually created myself that I will be releasing shortly in a few days.

You're also using WiFi, which dramatically improves battery life. I'd also be curious to see what your TWS is - tap on "cell standby" and see what your "time without signal" is. Some days, it's 0-1% for me; on those days, I see great battery life. Other times, I've seen as high as 50%. Those days, I get awful battery life.
In addition, there seem to be issues with the onboard DRM process running in the background (possibly a media hub thing), and other fishiness in general with the stock ROM. So, no, the Epic per se has NO battery issues, but the ROMs have some rather inconvenient bugs that have a significant effect.
BTW, congratulations on your 2^7 posts. It was such a nice number that I felt I needed to comment on it...

Yeah, my TWS is on 50% today... its always a hit or miss with that.
What I noticed is key with WiFi are two apps in the market, WiFi Status & WiFi Lock.
WiFi Status - This app will notify you that you have WiFi on when you are not connected to any wifi hotspots, essentially warning you you're using up more battery than you should be.
WiFi Lock - This app is key for me, it keeps your WiFi signal active even when your phone's screen is off. This prevents your phone from switching networks everytime you wake up your device, a HUGE battery saver I've noticed.
If anyone else has any other questions, feel free to ask.

Wait so you cant just set it to a no sleep policy with wifi from the connections menu? Not a problem to me, just curious

I may be wrong, so someone can correct me if I am, but I have yet to find a system setting that does this.

Nice and all but doesn't really mean anything at all. 21% Idle means that out of all that time, most of it wasn't in use at all.

Well, I just posted my best results but on average I normally get about 10-15 hours with my battery watching videos and playing games on my phone.

Yep. You're wrong. Under wireless networks hit the menu key and it will take you to the advanced wireless settings where you can choose to leave Wifi on when the screen is off.

We're not talking about the battery use percentage. We're talking about Time Without Signal, a completely separate metric that is reached by *tapping* on cell standby (not phone idle, which is yet another separate entity.)

Screebl is a power management app. We are talking about length of battery right out of the box, not modded with an app to control your power.
Right out of the box, no root, no custom recovery, I get 7-8 hours on a good day, with TWS at 50% all day.
Unplugged it yesterday at 630am, used for a little while, was plugged in from 9-10am by 230pm it was at 20%. Today, unplugged at 7am, its 10:30 and i'm at 70%. This gives me a STANDBY time of about 10-11 hours You don't see that as a battery issue?

Thanks for this! I had saw mention in another thread about setting the wireless to stay active but couldn't find where to do it.
Thanks!

I have no idea what is killing my battery now. Went to bed last night. Put phone in airplane mode and killed all the apps, shut down drm and GPS was left on but not in use since all apps were shut down.
Went to bed at 73%, woke up 6hrs later at 43%. No wigets at all except battery watcher. LauncherPro is my launcher. Display was off. That is an atrocious battery lose.

Speaking of battery saving apps, have you tried JuiceDefender? It's gotten me a few more hours of battery life.

I havent yet, just because I don't know what settings to use for it.
Could you possible post the best settings I should be using?

I was super frustrated yesterday because I got about 7 hours of battery right after I had just installed the latest mixUP kernel, which was said to improve battery life.
Then I read up on the DRM service bug, so I charged back up, did the normal airplane mode on/off, killed the OmaDrmConfigService from Running Services and now my life is changed forever! On 3G I'm sitting at about 4-5% per hour battery usage with GPS on, which translates to ~20 hours of life. If you haven't tried that yet, it's at least worth a shot.
Sure, there are some other things about my setup (mixUP kernel, SetCPU profiles, 1 hour sync intervals on Facebook/Twitter/Weather) that may get me to that 20 hour number. However, those have been unchanged since I went from 7 to ~20 hours of battery life. It seems that killing the OmaDrm service is really what knocked down the battery usage for me.
EDIT: Also, no JuiceDefender on my phone. My data flows freely. So that makes my jump in numbers even more exciting for me!

If I could get 1 day and 9 hours even using wifi that would be AWESOME! Please release that ROM!
Today, using wifi, my phone was DEAD at 4pm and I took it off the charger at 730am. I hardly freakin USED IT, maybe ONE 2 min phone call, ZERO texts and NO OTHER USE. In it's current form it's Totally USELESS.

incredible battery life New Nexus S w/ *SCREENSHOTS now

i don't know if I received a "dud" unit in the sense, but i have noticed INCREDIBLE battery life on my Nexus S with moderate use. the first day i had it (2 days ago), I charged to 100% and then started using it. I would say I did about an hour of browsing, an hour of talking, an hour or so of texting, maybe 10 mins of GPS use, and an hour of unlocking, rooting, etc. also just left the phone unplugged from charger overnight. on the first charge, there was a point where i was at 1 day 12 hours and 16 mins on battery and still had about 40% left or so. I even have a pic of the battery usage page I will post. *it should be noted that i turned off wifi, gps, etc when i was not using it. and did not use a live wallpaper. *edit: i also had background sync turned on the entire time. syncing gmail, contacts, calendar, etc.

That's over 2.5h "display on"-time and still 40% left, sounds quiet impressive. There's something wrong with your phone, in a good way.
If your numbers aren't accurate though, it's "normal". Idle use of 1% and less per hour w/o widgets and background active apps is nothing special.

it may also be related to you being on AT&T. i've read in various forms where people say that AT&T's mhzs (don't know the technical term) use less power than T-Mobile and WAY LESS than Sprint, which results in better battery life (the whole CDMA vs GSM thing).

The Sprint CDMA ones seem to have the most battery issues.

I'm actually seeing an increase in battery life with GRJ90....

My phone without mobile data on lasts about 20 hours...with mobile data enabled, but not necessarily active because i am usually on WiFi the battery life is reduced to maybe 5 hours...pretty bad...mobile here is Edge
Could it have anything to do with being in a bulding with thick walls? maybe the phone is using more power transmitting just trying to figure out where the cell is?

While it is true that bad signal harms battery life, 5h is ridicously low. Those 5h, how long is the display active in that period?
Check the battery status and see what is draining your battery so fast.
Try to change the WIFI rules from "turn off wifi when display is off" to "never turn off wifi" (you can still disable wifi the normal way, it just won't time out if there's a valid connection available), you can also set your phone to "2g only", if - as you said - your area has edge only anyways to further safe battery.

well its not a cdma vs. gsm thing, if sprint where able to purchase those frequencies they would have and it would have been different.
Much the same with tmobile them being so late to the game those are the best freq. they could obtain.
much like how sprint/clear's wimax sucks really due to bands it had to run on.

during the 5 hours, display is on for very little time....wifi is not a problem..when the display is off i still get email notifications and all that...i dont turn wifi off when i go out to the street and its constantly searching and i still get like 20 hours...but with 2g on, battery goes fast. I am not worried YET though, as my time at this 2G only location is about to end soon, then i will test 3G. I will spend some time in the US and plan to get simple mobile there...i belive that will be 3G with the Nexus S.
I do more tests once I get there...here I cancelled the 2G data this week since it drained the battery and i barely got 20kbits downloads (literally useless).

Out of curiosity, how much time were you getting before and after the update? I sold my two Nexus phones because I was getting maybe 5 hours tops with average (not heavy) usage!
I am hesitant to try the Nexus again, unless everyone says the update made the battery life much better for the CDMA version.

This is around what I'm getting (without a LOT of Wifi usage, maybe an hour 1 tops.....the rest is on 3G). The way I like to test my battery is to see how far I can go WITHOUT Wifi because of course it will last forever with Wifi on (should anyway). I can average like 15 hrs a day, with around 3.5 hours of display time on (really depends on what I was using it for) after the update....
Along with that, the new Gmail update will most definitely increase the battery life even MORE now because I keep EVERYTHING on, including:
- GPS AND 3G location services (use to turn 3G location services off, but the battery has been so nice on the Nexus I never found the need to anymore)
- Auto-sync turned on for Google Account services (Gmail, back-up, etc.) and Exchange account
- Exchange Push account (syncs 3 days worth of stuff)
- Auto brightness for my display (I drive 2 hours to work and 2 hours back, and on the way home the sun is constantly on the screen so it has to auto adjust for the brightest setting for however long I use it driving home from work).
I don't have many accounts syncing or anything (not into Facebook, although I have one) so that may be why. But prior to the update, my 3G signal was weaker so my battery would die a little faster (although I've ALWAYS been able to make it through a day of work with my Nexus). For me, the battery life has always been the best of any smartphone I've used, but after the update it seems a little bit better; not DRAMATICALLY better, just a little better (still can't touch the iPhone 4 on-call phone I had for work for a week......didn't have to charge that thing but one time during that week )
Again, this is with the Nexus S 4G

I meant 5 hours when it is sitting idle most of that time. Maybe 2-3 hours of actual usage.

I have going long as 15 hours with normal usage.

You seem not to be on Sprint (cdma) so this particular battery issue is not related to you...

I'm really amazed to be hearing about all of these phones with such terrible battery life. I have a Nexus S 4G & my battery gets me through half the day now this could be due to the 1750mah battery I'm using & then I'll switch to the stock 1500mah to finish out the day. I consider myself to be a fairly heavy user because I'm always on it sending text, emails, web surfing, phone calls, utilizing it as a hotspot & the only thing I've noticed that really puts a drain on my battery is downloading massive amounts of data, streaming data & watching movies on Netflix. I even use it to game online with my PlayStation 3 because I'm in an area where there is no internet & signal strength is all but none. I guess I too have an anomaly but nothing like a day & a half I wish. If there is anyway to extend battery life any further I would love to know.

I get amazing battery life on my Nexus S 4g. I owned the Epic and the Evo before the Nexus S and I gave up on those because of the battery life. I'm usually at over 30% at the end of the day. I do have the latest stable build of netarchy installed. I undervolted using setcpu and have 1 profile. Underclock to 200mhz when the screen is off. I sync my Gmail as well.

Terrible battery performance

I recently got a razr HD and i noticed my battery barely lasts a day. I had a flip phone before and it would last a week on one charge, i know i wont get the same type of battery life. I downloaded juice defender and set it to turn off my wifi/data when not in use. It has helped a bit since before that my phone would lose 2% battery an hour just in standby. I haven't downloaded any task killers, but when i'm done with my apps i go in to the settings and close them.

Two things to fix,
one, adjust your brightness to auto. The higher the brightness, the faster your battery dies, that is massive screen use.
two, poor wifi/cellular reception = ****ty battery, the phone uses more power to lock onto signal.
Dont use task killers, they do more harm than good.
I adjusted the brightness on my tbolt and I doubled battery life

Hmmmm. i wasn't very through with my post, but i have mine set on auto brightness. My wifi at home is usually 4 bars and 3 if im in the basement. I get 4 bars LTE for 95% of my day. In the main building on campus i get 1 bar if im lucky but usually its out of service so i depend on the wifi. The only thing i use my phone for is listening to music on my way to school, texting, email (but i set it to sync every hour), some light internet browsing, and calls.
Edit: Also on a sidenote is the smart actions useful? It seems like it does the same thing like juice defender.

yes, smart actions does the same thing with less battery,
UP your sync time! The more often you sync the more battery you use! I would put it on 4 hours and only sync if you need something important.
Turn of your cellular radios at school and that will help battery

Clearly your screen is consuming most of the battery. Try lowering your brightness, If you used it to text and kept the screen on for long time.. it might have consumed battery in that period. Not sure if its helpful or not .. but here are my battery stats after a normal usage day.

The 3 hours in sync shouldn't be eating up my battery though, but i guess every bit helps.

This is after taking it off the charger at 0800, I use my phone all day with limited smart actions.

nah, just change the sync settings to longer and set your brightness to auto and see what happens over the next few days and report back.

I noticed the biggest difference when turning off WiFi and mobile locations.
Also 4.1.2 seemed to increase my battery life dramatically too.

I don't think setting the brightness to Auto is the best for saving battery. When in auto, the light sensor is turned on and some processing has to be done to define the brightness every time the screen is turned on. And that consumes energy.
I always keep mine at 50% and, when in very bright places, I go for 100% brightness.

Hi again, today i disabled my wifi and data manually whenever i wasn't using them and manually enabled it whenever i needed it. It worked a lot better and i left my house with 85% charge and i used my phone a little bit more than yesterday and it used up a little bit over 25%. I also played around with my juicedefender settings and hopefully it will work better. I will set my brightness to 50%. I'll post back in a few days. And is my battery working properly, because i honestly expected it to last a lot longer. Also thanks for the suggestions.

I really like 2x battery for controlling battery usage by data connections. There a light version as well. It basically turns off mobile data when the screen is off and turns it on when the screen is turned on. It can do the same for wifi as well. The light version will reconnect and sync everything every 15 minutes (or you can turn sync off). I paid for the full version and it allows you to change the sync time to longer increments. I use it mostly because I don't want to have to remember to toggle and where I work the 4G signal isn't so great.

Have the same problem! Brightness is low, internet is off, when I don't need it, still the battery is weak!

You said you had a flip phone before and the battery lasted a week, is this your first smartphone?
Smartphones have a 24 hour battery life at best, This phone has an above average battery I have had 48 hrs out of it..
other things to get in mind is the ROM you are using, I see you are on stock Ice Cream Sandwich, ICS have a good battery life, I have tried Telstra Jellybean and it was not as good, I also get excellent battery life with epinter's CM10

I am very satisfied with the battery life! I also recommend x2 battery, which seems to prolong battery life with little to no impact on the usability of the phone (at most a potential short delay on emails when not on wifi). I generally use wifi whenever possible which use much less battery than the mobile modem. Also I have disabled a few stock apps that I don't use e.g. the non-gmail (stock) email app. The phone is not rooted and using stock o2 JB rom.

Wow sick battery life, do you have the MAXX HD?

I think it is as well. I admit it may be a little "inflated" by using Wi-Fi mainly rather but impressive nevertheless. Wi-Fi or not I generally experience good battery life. I have the normal non-Maxx edition bought in Germany September last year.

Also have a look using Better Battery Stats app to see what your most battery hungry wakelocks are, especially Kernel wakelocks.
I had issue when I first got my razr as I was using it on a network that doesn't have Fast Dormancy yet the phone has fast dormancy enabled, so i had to freeze it and battery life improved a little.
But unfortunately fo me the main problem was where i live. I'm in a city, so it's not a lack of cell towers, but for some reason at home my battery usage is insane while connected to mobile data, 9%-11% an hour with no use compared to 2%-5% elsewhere around the city. (Am thinking it must be getting bounced from tower t tower trying to get a better H+ connection) As soon as I switch over to wi-fi tho (which I have set to always on,) my battery usage drops to about 0.8%-1.2% per hour in standby.

[Q] Nexus 4 Bad Battery and S.O.T?

Hello everyone,
I have had my Nexus 4 for about 8 months now.
And to be honest I think my batterylife has been quite poor.
I'm currently using ParanoidAndroid 4.2.2 - 3.69 in combination with Matr1x Kernel
My phone is undervolted and due to Matr1x the minimum CPU frequency is 192Mhz.
I have JuiceDefender set to Agressive. And I no longer have any sort of Wakelock.
Location Services and Google now are Turned off.
I can get around 2 and a half hour Screen On Time with the screen Brightness turned to minimum and 3G on 70% of the time.
When my screen is not on I luckily don't have any drainage. The phone could stay on for ages. I just slept 10 hours and left it all with antenna enabled (Juicedefender turns off 3G by default when the screen is not on and only let's data through once every 30 minuts). The charge dropped from 73% to 70%.
When I'm at home and turn all my antennas off, activate wifi and connect to my home network. I can use my phone for about 3-4 hours with lowest screen brightness.
Listening to music with screen and antennas turned off doesn't seem to drain my battery by a lot when listening for a few hours.
So what I was wondering is;
Is this battery life normal?
I've seen a lot of people who have 4 hours screen on time with auto brightness outside.
Is this a hardware issue, meaning my battery is due for a replacement, although I can't remember battery life being better the first few weeks. I remember only getting 1 and a half hour screen on time. I was able to increase that by undervolting and lowering the minimum Cpu frequency. As well as installing battery management apps.
Here are some screenshots I took yesterday.

Hello everyone,
I have had my Nexus 4 for about 8 months now.
And to be honest I think my batterylife has been quite poor.
I'm currently using ParanoidAndroid 4.2.2 - 3.69 in combination with Matr1x Kernel
My phone is undervolted and due to Matr1x the minimum CPU frequency is 192Mhz.
I have JuiceDefender set to Agressive. And I no longer have any sort of Wakelock.
Location Services and Google now are Turned off.
I can get around 2 and a half hour Screen On Time with the screen Brightness turned to minimum and 3G on 70% of the time.
When my screen is not on I luckily don't have any drainage. The phone could stay on for ages. I just slept 10 hours and left it all with antenna enabled (Juicedefender turns off 3G by default when the screen is not on and only let's data through once every 30 minuts). The charge dropped from 73% to 70%.
When I'm at home and turn all my antennas off, activate wifi and connect to my home network. I can use my phone for about 3-4 hours with lowest screen brightness.
Listening to music with screen and antennas turned off doesn't seem to drain my battery by a lot when listening for a few hours.
So what I was wondering is;
Is this battery life normal?
I've seen a lot of people who have 4 hours screen on time with auto brightness outside.
Is this a hardware issue, meaning my battery is due for a replacement, although I can't remember battery life being better the first few weeks. I remember only getting 1 and a half hour screen on time. I was able to increase that by undervolting and lowering the minimum Cpu frequency. As well as installing battery management apps.
Here are some screenshots I took yesterday.

Your idle time seems pretty normal, but 3-4 hours OT on wifi is pretty horrible. I can get almost 6 with wifi only. and 4-5 with 3g/LTE. I'd try a different kernel. This worked well for me: http://forum.xda-developers.com/showthread.php?t=2256887 if you're on 4.2.2. You should consider upgrading to 4.3 I heard it gives better battery for a lot of people.
This also looks helpful: http://forum.xda-developers.com/showthread.php?t=2424729&highlight=sot

It does seem a little low compared to my phone. However your signal is pretty low a lot of the time which could definitely hurt your battery life.
Chrome is also very high on the list, were you using it ?

Yes, I was using it for around an hour I believe.
The low signal was because I was travelling with a train. But really, even with normal signal it's somewhat around 2 hours and half SOT on lowest brightness.

To be honest I don't mind paying for a new battery and changing up if the problem turns out to be the battery.
However I would first like to see what the actual issue is.
Because it would be pretty useless if I got the same results even after putting a new battery in.
My CPU governor is currently "OnDemand", what profile do you use?
I'm now testing Wheatley to see if I'm getting better results.

Running paranoid android with the screen on I was sometimes losing 2% every 10 or so seconds whilst on HSPA+, I don't know if that's my fault with kernel settings or what but on CM10 I'm at 70% at 8 hours of HSPA usage and just under 2 hour screen time.

Hmm, interesting.
Stock was a lot worse on My phone though.

Bump.
Should I contact Google?
Who should I contact for help on this?
I'm now trying Wheatley governor instead of OnDemand and undervolted an additional 25mV. Am I the only one with this type of battery life issue here?

I can get away with 1025mV @1.5ghz, I like interactive; in trickster mod go to hotplug and make sure min cores are at 1 as Matrix sets it to 2 I believe (this excludes screen off)

It was at 1 by default.
What do you like about interactive?

your battery life is normal. not bad, and not extraordinary. you can probably get more out of it though, control your apps and background processes. thats where the most battery life can be gained. how many apps do you enable to notify you of stuff? also, apps that are made to save you battery actually use battery, dont use them. battery life mostly comes from how you set up your device and how you use it. from what i see, you need to set up your device be more battery friendly, if that is what you are worried about. and chrome is terrible to use if you are that worried about your battery, the aosp browser is much much better.

My G2 is getting Crap battery life!

Hi Guys,
My LG G2 D802 is getting totally unacceptable battery life. I've tried everything but I just don't know what's killing the battery. I've actually got 4 hours screen time max (which is average for the G2) but I was expecting much more. Today, I've barely got 2 hours 45 mins screen time and 22% left... This is just mostly from reading facebook, xda, news apps etc. I've even turned sync to a minimum and am using easy battery saver so when my screen if of, data is off and syncs once every 30 mins for 15s. I have no idea why Android OS and especially Android System( in screenshots below, its used almost 50% of the battery).
What to do? I've attached screenshots of my battery usage and better battery stats.
Thanks
Sean

honestly thats about what I get.....stop comparing your stats to other. most of the time the people that have huge screen on time is because they stay in wifi areas all day, turn down brightness to 0 and turn off syncing completely.

I have sync on absolute min... I've disabled it almost... I was expecting much more from the G2... Even my old Xperia Z1 got 3 hours screen time.. I was at least expecting 5... Anyways, I've always got a strong signal (mostly 3G+4G) and use wifi for 1-2 hours a day so I really cannot understand that.
Also, I'm quite sure that the Android System and OS shouldn't be using so much battery... Something is definetly wrong there...

Not so. I get 5-6hrs screen on and usually go about 16-18hrs between charges. On the heavily modded stock rom. I have Facebook/Twitter & 2 email accounts and only control syncing with battery guru. I'm never on WiFi because my ISP stinks. I live in a great 4g area and have unlimited data so that's what I use.

Have you tried uninstalling/disabling any bloatware or apps you don't use?
Did you make sure your location services are turned off?

I haven't disabled or uninstalled bloatware but I don't use it... Still I shouldn't be getting this much battery usage from android system... Can someone put up a picture of their daily usage especially the % ?
Thanks

If you haven't already, I recommend you download the Gsam Battery Monitor app (available in playstore).
Take screen shots of every menu in that app after you've used your phone from 100% down to 10% and post in this comparative analysis thread.
For your reference, I get anywhere between 4hrs to a maximum of 6hrs of screen-on time depending on usage.

get cpu spy and check what frequency your cpu is at most of the time when not sleeping.
try a couple of battery depletion then charge till full cycles. If no improvement factory reset and try from there.
turn off gps/bleutooth/carrier iq if its enabled btw.

Having 1 bar of signal is probably killing your battery

I remove almost every bloated lg app from stock rom. But with 1 hour screen time with max 30% brightness screen is not the bigger drainer. It is android system with 37% usage. Processor worked 5 minutes, waking was 4 minutes. Yet how this could be bigger drainer than one hour screen time.

How often have you ran it down to 10%?
Are you using the OEM charger?
If you have like a 1000mah or 550mah charger, I'd try doing a slow charge overnight (it'll take 4hrs on a 550mah charger) to see if your battery life is improved.

I've been draining down to below 10% each time I've used it (5-6 times)... When I root later, shall I use one of those battery calibration apps? Trickle charge is out of the question for me as I don't have time at night to charge it and I use the OEM charger always... Let me root, try greenify some stuff and see if it helps...

You don't have time at night when you sleep?

I don't like leaving stuff on the charger and going to bed... I usually forget to turn it off

it should help recondition. just keep it on charger half hour after it says its charged.
At this point I would recommend doing a factory reset on a full stock rom. On earlier phones debloating could have caused a lot of errors and thus weird stuff happening we want to eliminate that. So going back to full stock might be last way of eliminating all else. After that I think hardware issue.
on full stock seek ways to disable that iq cartier, disable locations and switch off gps etc. Perhaps via recents, go to task manager then menu bitton and services. Disable all you dont use and check battery life.
this is all I know.
btw, this is first phone I didnt need to debloat to get amazing life

But isn´t debloating something to improve battery life little bit? Because all LG system stock apps drain quite a lot from battery.

amazing battery life for me
Iv been having amazing battery life. Yesterday from 7am-11pm the phone only got down to 47%. Of course with everything shut off untill im on wifi at home and when im not using data i shut it off. The one thing i know that uses wayyyy to much battery is google now. I turn it off and clear the data and cache. I even have my brightness at 50%. Right now the phones has been on for 5 1/2hrs unplugged and its at 90%. used pandora, watched a video on adult swim app and some light browsing.
