Love the phone, but can't get rid of LOS and Terrible battery

So I got the phone last Wed and have tried LoSTKernal, and with that I would get LOS all the time and it would reboot after sometimes. Also Wifi and 4g would sit at obtaining ip address forever and sometimes not connect. I then put 2.6.357_ZedomaxEpicTouchStockv1 on. Now everything works great except I constantly get LOS and also the battery sucks. I'm sitting at 67 percent right now and it was at 100 four hours and 13mins ago, and 70% of use is just cell standby and 12% was android os. I haven't really used it at all during that time.
Any suggestions? I am thinking of going back to totally stock to see how things function, since I didn't spend much time on that and see how it works then. I love the phone but won't be able to keep it if I can't at least get as good of battery life as my EVO had and also the LOS all the time.
When its sitting on LOS and idle, does that take up battery? Is that a possible cause of the terrible battery life?
Also random question about CMR, when I was first using it the power button worked as the select, but not it doesn't, and I have found the home button works to confirm a select, is this normal? UPDATE I just did a backup and power button was working again, and text was orange (was blue before), I think its a different version when I flashed Zedomax.

yes, if you are stuck at LoS for a while, it will drain your battery as the phone constantly searches for service. If you feel motivated and inclined you'd use one of the custom roms available at the dev forums. It makes a world of difference, especially since most of them remove the bloat.
I'm currently on Midnight Rom 2.2 with LoStKernel 1.0.2.4. Been on battery for 9+ hours, with 1 hour of screen on time. Full sync enabled. I typically get about 4.5 hours of on screen time playing a game/browsing.
Phone is great, just needs to be customized a bit.
oh .. you also need to calibrate your battery also after switching kernels. and if you feel inclined, you can use viper's LoS reboot script, works fairly well.
Also, this is in the wrong forum. Should be in General or Q & A.

Be ready to get flamed and called all kind of things ... why? For posting in the wrong section ... oh well.

I've tried all the roms here and two of them I can get 20+ hours with moderate use. Lost kernels help a lot, but the Rom by strong Steve I think his name is, the odexed Rom, is the only Rom I haven't had a los on. Coincidentally its the Rom I went 25 hours of battery with. Give it a try.

Thanks, I'm downloading the steve odexed now and then I guess I'll look into calibrating the battery. Sorry about posting in the wrong forum.

I'm flashing steve's rom now. For the battery calibration script, do you mean run this:
http://forum.xda-developers.com/showthread.php?t=1309034
Will that work with any rom? I'm not having much luck searching and finding what I should install for a 'battery calibration script'.

Try chriss almost stock kernel. Should clear that los right up. Also, make sure to post questions in qna from now on. Xda reserves this forum for development related threads only.

Just wanted to say that on the newest cwm, once you boot into recovery, start pressing the volume down button like ten or twenty times and you'll see it say something like back button enabled or something like that. Then you'll be able to use the power button like you were able to on all previous versions. Hope that makes sense.
Sent from my SPH-D710 using xda premium

here is how i do my batt calibration. i charge to 100 percent, flash the rom, make sure all is well, then plug the phone back into the charger until it hits 100 again. when its at 100 i reboot into recovery, and wipe battery stats 3 times, then reboot and download and enable juice defender. i then use it normally until it reaches 0% on the battery and shuts off. plug it into the charger and turn it back on until 100% and thats it. I have screen shots of 20+ hours every time (depending on the rom of course) . ive never downloaded any kind of batt script.

I haven't had a single LOS on strongsteve's ROM either. Actually, not a single problem whatsoever. I did choose to put back pulled stock kernel on this ROM though. Either way, you will be happy. Performance is identical to stock with the 3600 to 4000 Quadrants etc and great battery

Interesting.

I flashed Steve's Rom and its been working great! Wifi, 4g, and no LOS since I've loaded it, which is over 24 hours ago now. Also been using the phone with light to moderate use today and its been on battery 7 hours 20 mins now and only at 75% so battery life is looking good. Thanks for the help! I may try that battery process mentioned by twoeleven99 if I find the battery life to not be that great, but so far if it looks good I'll just stick with what I've got.

ics and battery life

At first my girlfriend had her Nexus S updated to ics and immediately we noticed a huge difference in how long her battery lasted and she is the furthest thing from a heavy user.
So when I heard that ics ws being released for our phone my first thought was i hope that what she experienced won't be what i do as we have a better phone right?
Well I am sad to say on a stock but rooted rom I experience the same lack of battery life as her.
Now I am no beginner to Android and have changed all sorts of settings available and nothing syncs on its own and when I unplug my phone from charging in the morning I will need to plug my phone in at night before bed as my phone will be completely dead.
I have to say I am very disappointed in the battery life of thr the stock rom and hope some good kernels make it out to help.

Have you tried to find out which app/process is draining your battery? Better Battery Stats can help you identify what is using up your battery.
I had a big keep awake problem when i first installed stock ICS on my T989D. I did a full wipe of the phone and formatted my internal SD card (after backing things up of course), reinstall the same stock ICS and everything works great now. Battery life is about the same as before (stock GB w/ Synergy kernel), which is about 30 hours with moderate use.

Try CM 9. I get almost 2 days of battery life.

Though I am now on AOKP, I had great battery life on stock ICS as well. But, everything is subjective. How many email accounts are being synced? Do you have Facebook / Twitter / G+ updating every hour? Do you have news feeds continuously updating as well?
I have to agree with the poster above. Get Better Battery Stats and find the culprit draining your battery and work from there.

biggest thing draining the battery is the screen.
you can literally watch the battery usage drop 10-15% in a period of 10 to 15 minutes which is absurd when its set to low.

Wait for kernel development. Its underway as we speak. It will make a significant difference.
Some battery saving tips:
- use juicedefender and set it to aggressive mode.
- use romtoolbox or other programs to underclock cpu frequency.
- also try using telus stock ics. Very good battery life.

I have a brand new T989D (I'm new to Android, former iPhone user) and got the ICS upgrade the day I got it (9 days ago). Battery life is terrible, I'm lucky if I get 10 hours of moderate usage. The phone also tends to run very, very hot. Sometimes apps freeze and all I can do is either wait or, in some cases, remove the battery to reboot.
I'm open to any tips that will get this fixed! I haven't rooted yet (no time). I think I will try those wipe tools and reflash the stock ICS ROM.
First post btw - glad to have joined XDA!

Stock, not rooted, my battery life is great. Something is using your battery up, and flashing some exotic kernel isn't going to change that. The stock kernel works fine. You'll want to find the root of the problem. Keep a real-time (or 1-5s interval anyway) eye on the phone's current (mA) usage, and when it's high for no apparent reason, you'll know that whatever is sucking your battery is doing it right then. That should help you characterize the problem. I've noticed when my WCDMA/GSM radio signal sucks, so does the battery life, so I either turn off the radio or switch to GSM only when I'm in that area. If your display is what's eating your battery, well a kernel can't stop that. Turn the brightness down, leave it on auto-brightness, or just deal with it if you need the display on all the time. But if tweaking and modding makes you happy, by all means...

I have the same complaint. The "screen" battery usage is just unacceptable, especially compared to GB. My phone has been draining from a full charge for ~4.5 hours and my screen usage is 70% and battery is down to 65% with hardly 10 minutes of screen-on time.

I use an app called autostarts and you basically enable/disable apps that start running when certain events happen (phone startup, wifi being turned on, incoming call/sms/mms, other apps turning on, etc.). Just make sure you do your homework so you dont disable something critical. Hopefully this app works on ICS. You'll be surprised what different events make certain apps turn on automaticly. Screen, data/wifi, gps and bluetooth are the biggest battery drainers. No matter what Rom you are on if you don't keep control of those items your battery will drain fast. Keep ur screen on auto, let it go off @ 15 seconds ( you have to be pretty used to your phone for that setting not to annoy you), turn OFF your data or wifi when not in use. With bluetooth and gps...well u know that when you use them your battery is gonna drain faster than normal...just keep that in mind. Its all pretty much common sense.
I'm not going to tell you how much battery time I get cuz its nonsense. There are times my phone lasts till the next day and others Im charging it by sundown. Then again Im still on Juggs n Darkside kernel and Im gonna wait a bit still b4 I make the switch. Also don't go by what other people say on battery life cuz if you might not get the same results on that ROM. Everyone of our devices is unique and acts different. Everyone user uses their phone different. You can't define "light, moderate, heavy" use so don't go by that either.

After upgrading to ICS stock unrooted battery life sucked (5-6hrs). I did the whole remove battery, factory reset and still sucked.
Broke down rooted (still stock), downloaded batterycalibration from play, followed the instructions. Easily get over 24hrs before having to charge again. and when I say easily, I mean I still have over 25% left.

Bingo. Vastly different battery life between ROM's is generally BS. Every once in a great while one of these threads has merit but typically someone saying ROM X had "Killer" battery life is clueless and drinking the koolaid. Then a placebo effect takes place. And definitely someones "Heavy" use is subjective. If someone says they get a day out of an android phone they are not heavy users by my definition. It doesn't happen with heavy use. Perhaps the Razr Maxx or another phone with a very large battery but I've had 5 Android phones. If I get past noon it's because I am not using my phone that much and forget about a full day. It's never happened in the 4 years I've used google OS phones. Never.

SOLVED: ICS Upgrade Myth Dispelled - Factory Reset Does Not Fix Battery Drain

EDIT: Please read this entire thread, there's some good info. Every phone and every situation is different, however it turns out my battery drain was the result of my phone not hitting "Deep Sleep". The culprit was my SD card, if you're experiencing battery drain after upgrading to ICS try removing your SD card and restarting your phone, use the app CPU SPY to verify your phone is now hitting "Deep Sleep". Again please read on, amidst some trolls there is more detailed information.
SIDENOTE: This being my first thread I have to say on the whole I really like this community!
I never thought I'd be that guy saying don't upgrade to ICS, because the OS is so slick and fun. However the glitch with the battery drain nullifies it's value. My brand new phone, less than two months old will die before the end of the day without me making a single phone call. I'm talking maybe an 1 to 1.5 hours of use texting, checking mail, surfing, and my battery now runs dead before I even get home from work. If you go into Settings > Battery it will show you the break down of what's using what. At the top should be your display, it takes a lot of power for to run the ultra bright display and this is what I saw before the ICS update. After the update these are the numbers:
Android OS: 58%
Screen: 18%
Cell Standby: 10%
Phone Idle: 7%
Android System: 2%
The OS is taking 58% of the battery?!? This is crazy!The buzz going around the net is if you do a factory reset it will fix the issue, well it does, but only for a very short time.
I went through the pain and formatted my SD card, then did a factory reset on my phone lost everything, well I backed it up, but still was a long process. After all that I loaded up my apps, and everything looked great. If you I went into the battery break down Screen was back at the top and the Android OS was several rungs below. I was SO happy! It was worth it after all.... THEN
Imagine my chagrin I woke up this morning to a full charge. Didn't make one phone call, just checked a couple emails, and being only a HOUR into my day my battery is at 76%!! I look back at the battery break down, and there's Android OS sitting at the top, draining double the battery juice as the screen display. I mean this almost makes ICS useless, what good is this great cell phone if you have to be tethered to a power cord. WTF!! Point being, don't bother resetting your phone, it DOES NOT permanently help. If you haven't upgraded to ICS don't, we're all just screwed until they come out with a fix, and you see how long it took them just to get ICS.
I don't know what happened between last night and today, but my hope is some dev person will read this and it will help them pinpoint the issue.

Having a bad battery would not make Android OS use the majority of his power though. I have had this problem myself in the past and never did figure out exactly what stopped it. Running Blue Kuban now and my battery life, though never great, is reasonable. FYI, I also run Juice Defender which makes a substantial difference for me.

Running pretty much stock ICS FF18, just have agat safe recovery/kernal installed. Yesterday I left Wimax on all day and when I went to charge it last night it had about 28% left. I made several phone calls, many texts/whatsapp messages, reading emails and using twiitter/fb a couple of times.
The battery life on this is not the greatest, for example, I forgot to turn off wifi when I left my house the other day, well my battery dropped about 30% in just a few hours. I now find that just leaving Wimax on all day is actually better and pretty much on par with just having 3G on, I prefer wifi at home but if I forget to turn it off it kills my battery.
I was so used to Blazers 4.1 battery life, the battery lasted forever and I could leave wifi, bluetooth etc on all day. Just hoping for the ROMs to start incorporating the recently released source so that we can get better battery life on these great ROMS.

This is all known information. That's why you use custom roms that have much better battery life.

I had same issue here with custom rom FF18 touched by SGS3. Went back to EL29, FF18 is glitchy and slower anyway.

Confirmed, factory reset battery drain exists.

OP, why don't you put up a screenshot of your battery graph? The expanded one, not the one that lists the percentages.
There are a number of reasons why this could be happening. One of my biggest drainers on CM9 was Google login service, turned out the "keep this device backed up with Google" in the backup and reset settings was completely preventing my phone from going to sleep. This is but one example.

ICS works really well for some, but for others it renders the phone completely useless. I'm one that it won't work for as well. The battery life is **** and 4g connectivity is non existent. As a result, I'm back to EL29/GB until a patch is made.
I spent 4 days after teh OTA was released trying to find fixes, trying to make it work, using different kernals and modems, but had no success. I posted about it many times and more or less was told that I was doing it wrong.
On that not, good luck mate. Here's to hoping for a patch from samsung soon. :good:

I have a thread stickied in general called "welcome to he et4g" that might be a good place for you to start, from there you'll figure out what you need to search for to learn more... there is no best rom its a matter of opinion, so read the dev threads and see what looks good to you... bottom line without seeing more information from you I would guess you have something running in the background preventing deep sleep, as mentioned earlier... also are you leaving wifi, Bluetooth, etc on? That'll kill your battery quick... do you live in an area with poor sprint signal? Constantly searching for service will also drain you battery. What do you have to set up to sync? And how often? There are easy ways to prolong battery life on ff18 and the vast majority of people complaining about battery life have not taken positive steps to learn more and resolve their own issues... it can be done, good luck

Help Battery Life

I have been stressing myself out about this for over a week, trying different things, buying new batteries trying new chargers, changing roms.
Turning so many things off basically making my phone into a dumbphone to try to figure out why my battery life is so bad. Could it be I just have a bad phone and need a new one??
I had a Galaxy S3 gave it to my GF, never turned any sync services off and I am able to get 20+ hours with that phone, this phone is HORRIBLE.
I was stock getting about 5 hours before dead battery (phone would get real warm- battery stats showing 33C+).
So I rooted and took it back to an LJC rom (4.1.1). Tried different modems, kernals, files tweaks with root explorer.
I bought BBS, a battery calibrator from the market and still cant see any problems that would do this?

last picture......
Should I just take it into Sprint and get a replacement???

I am running Macintosh 3.0 and I have power saver turned on, and I run DS Battery saver all day long. I am getting 2.5 days solid with moderate use. I am pretty sure DS Battery Saver is what is saving my battery. Let me know if you want to try the app. I have the .apk saved on my sdcard.

Also try uninstalling and reinstalling facebook. My girlfriend's phone (GS3, not a note) went from 8 hours to probably 14 hours just by using the mobile web version of facebook instead of the the app. Facebook is atrocious at making apps.
But it really does sound like you got a lemon here, I'd get a replacement from Sprint. I don't think I could kill my battery in under 10 hours unless I was playing a game non-stop. My phone is completely stock.

I will uninstall Facebook, and test it out. Thanks!

OP. Your problem is not your ROM or anything else. Jeeze people.
Those partial wakelocks are PURELY from Google Now and the wifi/network based location. Either turn off Google Now, or turn off network-based-locating and those partial wakelocks will disappear....I'd also wager you have Sprint Connection Optimizer still running causing your phone to hangup trying to find a network conenction.

My battery took a good hite when I updated to 4.1.2 used to get 20+ hrs with 7+ screen time now I get about 14-15 with 4-5 hrs screen time

Ok I turned off Google Now, network-based-location, and Sprint Connection Optimizer. I have also installed DS Battery Savor Pro running in balanced mode. I dont have facebook installed anymore also. Here are the screens, still just as bad........

Based on your first pictures, your status bar, and the amount of awake time your phone is showing I'm guessing a couple of things. Do you have a phone signal where you spend most of your day? If my awake bar was solid like yours I wouldn't have a battery after 7 hours either. I would backup everything and do a full wipe / clean install and run the phone a day or so.

What of the borderline useless bells and whistles do you have enabled? I.e. face recognition/unlock, auto-brightness, SPen battery saver etc? Things like battery savers unsurprisingly don't help so i'd nix it as it is only wasting battery.

Meh. On this device I always aim for getting 10%/ battery usage per hour of screen-on-time on TouchWiz ROMs, and a fraction of a percent per hour in screen-off....something is burning battery here, and it is probably a system setting.

I am going to try that now, going to do a wipe of everything and not install anything except the battery tools.

No face recognition/unlock, auto brightness is enabled, but with that little screen time does it really matter? No SPen battery savor. Thanks for the suggestions.

The thing is, I have a Galaxy S3... The Note II is setup no different then that, settings or otherwise. I am trying all of these suggestions, but why did I not have to turn any of these off on my S3?? Same service area obviously. I took the Galaxy S3 off the charger last night at 100%. Put a new battery in the Note II so it was at 100%. Let them both sit on the counter for 1 hour. S3 had 98%, Note II was at 87%... No calls no texting, no screen time. It is so fustrating! I have had my fair share of battery tweaking with previous phones (HTC EVO, HTC hero). It seems something isn't right. I had problems with stock rom, that is why I rooted so quick, to try a different ROM.
If the wipe does not work I will try to get Sprint to get me a replacement, was hoping the get this figured out before I fly to Florida for a week. Good thing I have extra batteries.

I would get a replacement. You should not have to turn off all thr features to get decent battery that defeats the purpose of having a smartphone.

Bought Ds Battery savor. Charged phone to 100% put it in airplane mode went to bed at 11pm (phone at 100%), woke up at 7am and it was at 8% Fail! 0 screen time, 0 talking, zero everything and lost charge in a little over 8 hours! Going to use it in florida the next week, with my extra batteries and most likely going to return when i get back
Thanks All for your suggestions!

[Q] Battery Life Issues

I received my S6 Edge on Wednesday and rooted it the same day via Ping Pong. I'm on G925TUVU1AOCG. Is that even the latest version? Anyways, battery life is literally ****. I can't get more than 2 hours of Screen on Time. Even my Galaxy Nexus from 2012 gets at least 2+ hours.
Is this because I'm not on the latest version, rooted, or something else people have experience with?

I've had horrible battery life since I've rooted using ping pong this week. I don't think my phone is going into deep sleep but haven't checked it yet. It drains fast when not being used.

Yea so I flashed the stock ROM with Odin and unrooted. I didn't wipe data however. But battery life still sucks. For anyone that cares .

I read a trick about disabling google now and it seemed to help drastically.

I went through this issue with my first S6. Re-root and download better battery stats - or CPU Spy. See if your phone is going into deep sleep. Mine was constantly kept awake by lli_pm_wlock. I couldn't find ANY information about it on the internet - but it was keeping the cores active and burning through battery like crazy. It would occasionally enter deep sleep, but only for a few minutes at a time.
I ended up returning the phone and getting my new S6 Edge. I tried everything - factory resets, flashing stock firmware via Odin, basically everything possible without tripping KNOX with a custom kernel.

My battery life has been awful. Specially after rooting with Ping Pong and specifically last night. 100% at 10PM, and at 11AM with 58 minutes of on screen time, the battery was at 13%. That is just horrible. Worst battery life I have ever gotten out of the phone.
Pains me to say it, but if the battery doesn't improve by unrooting it, and waiting for a future update to 5.1, I'll most likely change to a LG G4.

If you have it rooted install Better Battery Stats and figure out the problem. If it's a wakelock, the problem is it's just not going to sleep. Something is keeping the CPU active even when the screen is off and nothing is going on. It's a common problem on the rooted phones - but usually PingPong Root doesn't have the issue. Enter recovery (turn off - then power, vol up, home at the same time) and clear the cache. Reboot and run BBS for a while.

I also have the same experience but instead I just keep my phone on Ultra Saving mode

It's been really difficult for me to try to drain my phone to see my average screen on time.
But is this normal? I'm not sure what is a decent Deep Sleep percentage.
Btw: This is after I unrooted without factory reset.

Yea we're having very similar issues. I would try the G4, but the Edge is too beautiful!! This is the first time I've gotten a phone so soon after release, so I'm probably gonna stick it out for a month or 2 and wait for bug fixes.

So I purposely didn't charge it last night, and you can tell it has really really bad standby time.

Try disabling WiFi or set it to keep it on only when plugged in.

That is not normal. Backup your data and flash stock firmware with SmartSwitch then restore what you want. See if that makes your battery last any longer.

I had horrible battery life when I got it out of box. It wouldn't last more than 5 hrs with very little use. After I flashed stock firmware with SmartSwitch, Battery+ RAM Usage issue got solved. Now I get whole day with single charge. I take my phone out from charger by 7 AM and by the time 10 PM in night, Phone would still have 35-40% battery left. I get many emails [50+], 2hrs of GPS+Music streaming + random facebook & Instagram and even after this, I get good battery life. So I would 1000% recommend that you do a flash stock firmware with SmartSwitch.

I tried using SmartSwitch and unfortunately, battery life was only a tiny bit better. However, I started getting a bunch of force closes, and the phone became laggier than before. I would try it again, but it's so much work resetting up my phone! ...especially without root.
So I ordered the G4. Hopefully I'll be getting the Note 5 in a few months .
