Battery drains within a few hours... - Galaxy S II Q&A, Help & Troubleshooting

Snce I have updated my GS2 to ICS my battery drains insanely fast. I don't even do anything with it. I go to the battery consumption table and it seems like the screen is overusing the battery. The rest are fairly normal percentage.
Like I mentioned in the beginning I only have this problem when i'm using ICS. Right now I have the stock ROM that I downloaded from SamMobile. When I'm using custom ROMs it gets worse. What could this be?
And yes I did try to search for similar problems, because it seems like a lot of people have problem with the battery but no one had the exact same problem as me.
I can just add that since I last charged my phone my screen has been on the lowest brightness and the phone had just been lying on my desk. I haven't even touched it. still 7% has been drained and the screen seems to do the job.
Does anybody know how to fix this?

Same to me....Plzzz guys...Help US.

Battery drain is the hotest topic on ICS these days. I believe the high RAM consumption of ICS is causing battery drain. Almost every ICS rom is having this issue. You are not alone. Relax and wait, you will see improvements.
-
In the mean while, you can install "betterbatterystats" to find out what is draining your battery. Good luck.

Percentage means nothing. What is your screen on time? (Click on display to show these details)

Well now the screen has been on for one hour it says and my battery is on 77%. This is messed up...

So when you clicked on display, it showed that screen on time is 1 hour, and your battery is currently at 77%? That isn't terrible, actually. That means you're on track for a little over 4 hours of screen on time before your battery will reach 0%. Average screen on time for full battery discharge is usually around 4-5 hours.
If you are using the phone, and the screen is on, the battery WILL drain.

No believe me this is not good battery time at all. I have screen on lowest brightness and barely use it. Even when it's just lying there with screen off it drains a lot. I mean I have had this phone since last summer so I have had it or a while and he battery was pretty good before. But since I updated to ICS the battery drains a lot faster than before.

You just said the screen said it was on for an hour, and the battery was at 77% in your post above. So was that not accurate?
If it is draining more since you upgraded to ICS, and you want it to get better, then you have three choices:
1 - Install BetterBatteryStats and other monitoring apps to figure out what is keeping wakelocks and other processes running on your phone that is draining battery...
2 - Do a factory reset/full wipe and see if it was an errant app you installed that could be draining the battery, then slowly start adding your apps back one by one... or
3 - Flash back to a Gingerbread firmware.

Yeah I guess you're right, but at the same time the battery is very very bad compared to before so I'm confused. Maybe I was just enjoying a really good battery time back on Gingerbread?
1. First of all that BetterBatteryStats is too complicated for me. I tried to use it before I didn't get it. What am I supposed to do when I find something that is draining my battery. Should I freeze it? Uninstall it?
2. I have tried this a lot of times, no change.
3. If I use Gingerbread for some reason the APN settings with at&t doesn't work properly. I lose connection very often. So I'll rather have worse battery time for now. Is there a solution to the internet connection?
Thanks man I appreciate you taking your time!

What modem/baseband are you using with Gingerbread, that could make a difference with mobile data dropping.
Also, what APN settings for AT&T are you using? There are a few different APNs. The two major ones are "wap.cingular", and "phone". The one you should actually use will depend on what kind of data plan you are signed up on.

When I'm on GB I use KL1. Is that what you're asking? I had no idea there were two different APNs... I use "wap.cingular"
Do you have the APNs for "phone?" It would be awesome to have that. Then I could just go back to GB until they fix it.
BTW I checked my battery stats again, 24% left. It says screen 56% and Time on: 1h 54min... So it's is pretty bad, right? . It dropped really fast.
Android OS is second with 15%.

APN for "phone" doesn't work unless you have a specific data plan - namely any 4G plan. So if I recall from some of your past posts, (I remember you now) you're on the non-smartphone data plan, right? Then the "phone" APN won't work for you if you are.

So you're running a clean flash? No downloaded apps installed yet? Yeah, that's terrible. Sorry to hear. I would go back to Gingerbread.
Reading stories like yours makes me glad I'm still ON Gingerbread.

The problem is that I'm not really using the screen that much. today I have just listened to music, not even used the screen that much. Just text a little bit an nothing else.
But still it shows up as if I have used the screen more then the other apps running in the background. Remember my screen is on LOWEST brightness level and I barely use it.

Stock XXKI3, (2.3.5) I have several mods though.

If all else failed, try shutting down your phone, take the battery out and clean the battery contact points. Dirty contact points might be the culprit.

[Q] "Suspend" + "Events/0" Processes Draining Battery?

Hi guys,
So for the past week or so, I've been noticing really bad battery drain on my GS2, and I think I have finally pinpointed the problem.
"BetterBatteryStats" has told me that there are 2 specific wakelocks running in the background, which prevent the phone from going to 'deep-sleep'. These are the "suspend" and "events/0" processes. They are on for hours, preventing the phone from going into a proper 'deep-sleep', and keeping it awake.
My question is, how would I stop these processes from running? I know for a fact that it is not such a common 'bug', because tons of people are getting >18 hours on their GS2 with moderate/heavy use, while I'm only getting about 10 with light/moderate usage.
So in short, why are the "suspend" and "events/0" processes running while the phone is supposed to be in sleep mode, and how do I stop them from running and draining battery?
Thanks everyone!
Well I don't have that problem so can't say. You should ask it on the BBS dedicated thread,
http://forum.xda-developers.com/showthread.php?t=1179809

This is the famous "Android OS" bug, which happens only on SGS2. Search the forum and you'll see quite a few threads about it. There is no solution, but keeping wifi off when not in use or setting is to sleep when screen is off helps quite a bit.

It's not only a bug on SGS2. I've been fighting this problem for quite a while on my Nook Color with CM7. Here's the thread I started.
hmm, I am having this problem as well, I'm used to my iphone, where i can use it all day and still remain above 50% meanwhile every time i pop the screen on my GS2 the percentage is down from last time. its horrible, very much considering going back, I love this phone, but this battery draining situation is out of control for me.. midnight -8:30 i lost 45 percent battery.. screen off..

well for me, installing the siyah 1.8 kernel has sorted it and my battery life is pretty damn good now.
Others will tell you its not fixed and the extra battery life im getting is a placebo. But all i know is i used to get 3 hours screen on time and lose 15-20% battery overnight. Now i lose 2% overnight and get 5-6 hours screen on time. If thats placebo then so be it.

hmm, ok, I will look into kernels, I am using an AT&T SGS2 so its a little different kernel wise. I have yet to find anything in my specific forums though.. just switched from an eperimental kernel to a stable, so maybe this will help
I think I just read somewhere in the Galaxy S2 forum that AOS isn't exactly solved on the .14 kernel (which siyah 1.8 is based on)..... it just merely not include suspend and events/0 into the Android OS count for the battery.....
Anyone can shed some light on this?

is siyah 1.8 better for battery life compared to siyah 2.1 or the newer one?
I tried 2.1, but I still have high android OS.
Using bbs, I see that suspend and events/0 is still around 1 to 3 minutes each day.
I have turned off:
Accounts and sync > background data & auto-sync,
Privacy > back up my data,
Location and sec > use wireless networks.
Any other advice?

Use a 2.3.4/2.3.5 based ROM such as CheckROM HD or Hyperdroid-Androidmeda with Darknight-Siyah Kernel.
I get 3 days of use if i keep data off . With Data on and normal usage i get on average 0.7-1% drop per hour compared to 3-4% of 2.3.3 ROM.I think it's a combination of kernel and ROM that solves the problem.
Earlier CPU Spy used to show lots of time spent at 800Mhz which is what android OS bug does. Now i see it spending 1-2% time in 800Mhz and most of time in deep sleep.
thanks for the reply.
now I am using CRv3.1.1 with speedmod 18test3.
but it seems that from day to day, events/0 & suspend are getting bigger and bigger.
do you know why?
I upgraded to KI3 a long time ago, and froze the hubs + wifi sharing / wifi sharing manager (i never even used the hubs anyways), and what do you know; my battery can now easily last me a LONG time, after 16 hours it still always has AT LEAST 40% remaining, and that is with a few hours screen-on time, data sometimes on, wifi usually always on! I'm extremely happy now!
So in short, for those of you with bad battery life, the least you could do is upgrade to XXKI3 or XXKI4 (they're pretty much the same thing) firmware/kernel. Even completely stock without root/frozen apps is A LOT better than any other 2.3.4 / 2.3.3 ROMs.
CRv3.1.1 is already based on xxkj3, and I have already frozen most of samsung bloatware.
However, I have just found out that kernel is an important factor in high suspends and events/0.
Now I use the previous version: speedmod 17 test 1, and suspends & events/0 decrease a lot.

[Q] Battery Life ICS vs GB?

Just throwing this out there, I have played around with a few of the ICS roms, using safestrap installs, to retain the back to GB option. I have found that I get about 50% less battery life on the ICS roms. On an average day I use my phone moderately, past two day, back on GB, at around this time of day I am at about 60% battery. While on ICS leaks, I was at about 30% with similar use throughout the day. Anyone else have such a stark difference with ICS?
You have to give it at least a day to settle in. I get better on ics.

I have stayed on the Roms for several days(a week on first round of trying them out) and still much worse battery life. You are on the GSM Razr? I am on CDMA, you know of any difference with radios that would cause the difference? Generally have LTE off both GB and ICS.

if you go into your battery usage youll see that your screen is using 50% or more of the battery. there are battery issues and moto knows about them, im hoping they will fix this, ive read articles that they are gonna fix this bug before releasing the ics to the public.
my battery is the exact same way on ics, i hate it, but since i got a maxx now i could care less. i accidentally deleted my screen shot of the battery usage. and if you look at the ontime of your screen youll see that it is a 5th of the ontime of phone, (at least for me it was)

I was a bit hesitant to agree about there being a battery issue, until i was satisfied that id had enough time with the ROM.
But the truth is in the pudding so to say... I am able to make it through the day but i am getting at best 2/3 the amount i was on gingerbread.
9.5 hours of battery, 80% of which was taken up by screen time of 4hrs.
Yesterday i was convinced battery was fine, today i know there's something's amiss

I have found the exact opposite. My office gets horrible cell reception and my phone was constantly trying to connect on gingerbread. It would always show the kernel as using the majority of the battery. Since ICS my phone rarely drops connection and my kernel now barely consumes any battery. I'm making it until five everyday with 50% battery left while with gingerbread my phone was always dead by five.

I was in the soak test, 1st I got the standard email getting everyone's opinions of the soak. Then yesterday I got a 2nd email from the MFN for a 2nd survey. This 2nd survey was all about the battery life. So, yeah, Moto knows that there are some issues with decreased battery life. I've noticed a decrease in battery life. Even so, I'm still happy with ICS. Most of the issues I've noticed have more to do with apps than ICS itself. Some apps, when I want to go back a screen, it instead takes me all the way out. Even the XDA app does this. Anyone else notice this issue?
I'm not 100% sure what the cause of the battery issue is.
In my case, on GB I would could typically go from about 6AM to 4PM before I would need to charge it again on a normal Droid RAZR. On ICS, at first I could only go for only about 2-3 hours before experiencing a 50% drop in power - meaning only about 5 hours before needing to hit the charger. For this reason, and other issues, I opted to perform a Factory Reset. It solved the problems I experienced, including my battery issue. On ICS, I can now go from 6AM to 6PM with a battery meter reading of 50%. Translation - for the first time with this phone and normal use (for me) I can go all day without having to worry about a charger. So, this is a huge improvement. But it did require a Factory Reset for me to get this level of performance.
I would like to be able to say the same but.... I did a factory reset before and after loading ics.

Just curious, when you installed, how did you go about installing/reinstalling your apps? When I did the reset, I just let Google Play do it automagically for me. It got me about 90% there. There were a few things I needed to add and configure. Also, I stopped using another launcher and just went with ICS. I don't know if those are differences that might make a different or not.
I actually did not let google restore anything. I wanted a fresh base to work off of. Installed from market one at a time.

Actually the first china leak (120) gave my battery a lot more usage time,significantly.
But when i switched to MIUI rom my battery life significantly dropped down,every minute of usage=1% of battery .
Try to use the stock rom for a couple of days,at least the stock leaked china rom has very good battery life for GSM devices .
I've had ICS for a week now. At first my battery didn't lady add long. But after a few days and a FDR it its lasting longer than it did on gb.

Values 5-10% for "Android OS" are the values of my dreams as I am used to +/-25% on the GB...

[Q] Terrible battery life

Somehow, it seems over time battery life on ICS has consistently diminished. May try some things but this is stock rom, and really not a lot of apps widgets. Is everyone having this?
Example, Sunday I unplug it at noon, and by 7 its at 4%, made a few calls, say 3 under 5 min. Used navigation some, texted some, and a bit of fantasy football app. But that seems below reasonable expectations.
Widgets: 1 weather, Tim Hutt ICS calendar, SiMi Clock, battery & Weather(lockscreen), Widget Locker, Google Music. Launcher: Apex pro.
Did a bit of surfing and didn't see much around stock ICS (could have missed it)

I'm on the US AT&T stock ICS. Have not tried any roms.
If you upgraded via kies or OTA...the chance of a corrupted flash is high.
I'm not saying that it is, but we have had several reports of failed OTA or kies upgrades to ICS...
The only good fix is a re-install of the build...
I would go to samfirmware.com, and push the rom to the device again, and then test the battery life.
this would not be the first bad rom image we have seen from the upgrade.....g
And remember, it takes 3-5 days of normal usage after a fresh install, for the dalvik cache to build, and for the device to "settle" before any accuracy can be measured...g

If this is the case, should I try something like a factory reset then reinstall? I initially updated via Keis.
What is typical battery life on ICS? I recall I got the note right before going to SXSW and it would run from 8am to 11pm with solid use and maybe a 10-20% top off somewhere in the day. This has given me serious cell phone "range anxiety", even bought a external battery to address it.

Best screen on times I've seen are ranging from 3-4 hours, and overall battery times are going 18-24 hours...
Now mileage varies greatly between users, and i'm running ICS as well, and since 6 a.m. today, I've used 14% battery in 7 hours...
I've made 2 phone calls, sent 3 texts, and messed around with settings for about 30 minutes...
It does sound like you may have gotten a dirty flash image...but it's so hard to tell, unless you get random freezes, boot loops etc.
But the stock ICS battery life was horrible for me........g

It boots and actually runs fine. Occasionally cell standby chews the battery out of nowhere, andriod os and phone idle too.
I pulled it off the charger today at 9am and as of 2:00 I was at 68%. Checked email, messed on flipboard while making coffee, updated a few apps. Checked traffic. Mostly just sat on my desk.

Understood ...
Fortunately, the note is painless to use on custom roms ...
With the ATT version, you simply push a custom recovery to the device via Odin, then download and flash the rom.
No root needed. And if you don't like it, you restore the stock nandroid backup and presto...no more rom.
Root is very nice though, as it allows sooo much more control ....g
Extra Batteries, their cheap and totally worth it just make sure you get a wall charger too
I've pretty much given up on eking out more battery life since it seems universally bad.
A bit more than 4 hours screen-on time seems to be the limit without setting the screen to ultra dim.
Standby seems entire dependent on my signal strength and whether I have LTE enabled or not. If it's strong, 24+ hours isn't unreasonable.

Phone battery draining quickly after JB update

Hi,
I have recently (half a week ago) updated my SII to Jelly Bean from ICS. It's fully stock without root. However, I noticed right away that the battery started draining very quickly and the phone sometimes gets hot. Did a factory reset. Factory reset the phone and format the internal SD and remove the external SD. Didn't help in the slightest. Phone starts draining after resetting. I have tried to flash another stock JB ROM (XEU) and afterwards factory reset the phone again. No dice. I installed CPU Spy to see CPU consumption and it says the phone didn't go into deep sleep at all and 95% of the time it was at 200 Mhz over an 8 hour period or so. So there's a wakelock that's keeping the phone continuously on.
At first, "Media" in battery settings in Settings was the culprit, it drained about 50% of the battery. I have searched the web and it's a pretty common battery drain on JB. I did try to disable the service and its battery consumption went down dramatically. But for some reason it turned on again. But right now Android OS and Android System are both draining most of the battery. I have also installed BetterBatteryStats and according to that app there is a partial wakelock called "NlpWakeLock" by Google Services that's draining most of the battery. Last night, around 60% of the battery got drained overnight (80% > 23% to be precise). Which, clearly, is unacceptable.
I'm at my wits end. I have no idea how to solve this and because I really like the new JB features I don't want to go back to ICS (I did a fresh ICS install and the battery drained 2% overnight which is how it's supposed to be).
If there's any information you need to know let me know. Any help is appreciated!
Go back to GB with speedmod kernel is an option.

Do you mean going back to Gingerbread? I haven't figured out what the speedmod kernel is yet but if I were to switch back I would rather switch back to ICS. But preferably I'd stick to JB since I do love all the new features and options. I'm willing to flash another JB ROM without the battery drain issue. However, all stock ROMs that I have tried had the issue.
Do you know of any good JB ROM? I prefer to keep it as stock as possible. I did root when I had ICS installed though.
Battery Drainage is very common in JB Stock

Hey Kaigo ,
I have faced the same problem as you have faced ... Gone through a lot of problems to fix this Many of the Stock JB's for GS2 are having a lot of issues with the battery drainage
Well I had found a solution to this problem You can try installing the JB France update (XEF) & the UAE update (XSG)
It worked pretty well for me Try it and let me know if it worked for you

Well repeating other peoples posts isnt helping anybody.
An update. I've installed the XEF update initially it had the same draining issue. However, I've also cleared cache and data in recovery mode and it seems to have solved most of the issue. I've got pretty good battery life now (about 1%/h idle).
But I did find another culprit draining the battery which is Dropbox. According to BBS the processes "wlan_rx_wake" and "h2_hsic" were draining the battery but I've uninstalled Dropbox now and it seems to have solved the issue. I really use Dropbox regularly though. Anyone got any idea what could be causing that?
Thanks for the help so far everyone! :laugh:

I have always had that feature disabled since I don't want to use it anyway. I have no clue what could be causing it. I want to use a packet sniffer to see what is sending and receiving data but the phone isn't rooted so I can't really do that unfortunately.
Hold on, I'ma freeze it with TiBu.
Test time.
PS: You really need to root that phone.

I just greenify Dropbox (actually, all apps which rely on an internet connection). Unfortunately for you, it requires root. IMHO, almost worth rooting for, although there's many better reasons than that.
Greenify is almost like a temporary freezing of the app, by stopping all background processes for the app. They automatically restart when you launch the app, and automatically turn off when the phone goes to deep sleep.

Well Dropbox always keeps on syncing stuff from the cloud and that might the real cause You should disable all the automatic syncing and keep it to manual sync as it syncs only on your commands and saves your battery!!

Check how much data is being downloaded. If a lot is being downloaded off WiFi, switch it off and see if that stops your drain. Then switch off Data on your cellular. Just to check which one's causing the drain. Believe it or not, I just rebooted my home wifi router and battery drain issue was over on my Galaxy S2.

I had previously rooted my phone when I was on ICS. I never used it too often though. I wanted to use Nandroid. I have no clue how to root JB though, without flashing a modded kernel (which I did with ICS).

That's very interesting. This might just be a good reason to root the phone. So I can use network log or shark to see which apps are sending and/or receiving data. I have this feeling Dropbox is going to be one of them..

Hmm, but I guess that you can't really freeze apps like Whatsapp, since you wouldn't be able to receive any messages then until you turn on your phone. But I'm getting convinced to root the phone again so I'm definitely going to give it a try.

[Q] Poor battery life Verizon SGS4 ME7

So here I am, upgraded from the GS3. I understand that the ME7 radio is locked and that safestrap is the only option. But here's my dilemma. I used to get 14+ hours of battery life on my GS3. Now I'm lucky to get 8 hours, if I'm not touching the phone whatsoever. I've tried stock, Jellybeans, and Darkslide (seems to be my only options but feel free to prove me wrong.) Is this normal? Do I have a defunct device? This just seems extremely poor to me... They can't advertise that this phone is so much better if it's getting less battery life than the fricken S3...
Side note: I've tried running w/o my apps, and by turning all of the motion sensor stuff off, but I do not see a difference.
I also am pasting a picture of my battery in stock. You can see that in one day, I have to put it on the charger. Yes, I use wifi, but I honestly wasn't using the phone (and I do not have my apps installed.) The first fall on the graph is me using netflix for an hour (battery decline here is understandable). The second fall is my phone sitting on my desk while I'm at work. I'm on my computer, not my phone... and it's almost declining as much as if I was watching netflix. I've restarted it.... used the android task manager to kill the ram... you name it... Every rom I flash I've flashed is like this. It's astronomically frustrating...

It's obvious that some apps you have installed are causing this, I can get 14+ easy on mine. I highly suggest using Greenify to hibernate misbehaving apps and try to use auto-brightness if you can stand it.

A different rom wont make much difference if its something with the settings or a specific app you have running constantly. Do you have location services enabled. Thats a big one that causes alot of drain.

I will definitely take a look at Greenify, and see if it helps me. Thank you for that suggestion.

" I did a ton of reading on this prior to flashing, but from what I see people are only reading my first sentence and trying to answer (which is why the, "Doing a little bit of reading goes a long way," comment irked me.) I have been a rooted android user since Droid X, so I know how to read/research/troubleshoot phone issues. Believe me, I've had to SBF that phone a million times because each flash was like a crapp shoot. This issue however is a commonality between multiple SGS4 roms (Stock, Jellybeans, and Darkslide).
I always shut my location services off the second I flash a rom (unless I need to use my navigator, which as mentioned, I don't have installed at the moment.) But this is definitely a valid troubleshooting question to ask.

Turn off Google location services, see if that helps. That was killing my battery on ME7, same as yours. If your not into rooting, the 4.3 update has fixed that bug, I'm back to 3.5ish hours of screen on time. I did give up root though, so pick your battle i guess.

FYI it is possible to retain root and take the update as explained here: http://forum.xda-developers.com/showthread.php?t=2504408 If you've already updated though you'll just have to wait for an exploit.
To the OP: It's also possible you just have a bad battery... there have been cases of faulty batteries and some were even swelling up so perhaps you could try to get a replacement to see if it fixes it.
Here is a post I made a few months back..I was battling Horrible Battery life (approx 5-10% per hour). Since i caught the culprit in my home netork I get less than 1% drain idle per hour:
"I had bad battery life on my S4 right after release. I tracked it down to Multicast being ENABLED on one of my Access Points. I would recommend logging into your routers and/or) access points and look for anything related to Multicast and Disable it (or uncheck it).
Granted this was for a totally different device (note that my Nexus 7 was NOT affected by multicast) but it certainly cant hurt anything by disabling multicast..If it does, just enable it again.
My S4 was using approx 5%-8% of battery per hour with multicast enabled...once I disabled it, I now drain about 1% per hour.
This took me almost 2 weeks to discover...keeping in mind that my S4 never connected to the affected AP. I use that AP for older legacy devices.....just having it on the network affected my S4.
Give it a try..if it does not work..enable it again."
PS..disabling Google location services also helped me slightly with a runaway battery drain.

Ya, I saw, but not having root is kind of a penance, makes me appreciate having it more when I do get it. I've also decided flashing roms gets old, but for sure I'm missing Xposed framework.

Here is a post I made a few months back..I was battling Horrible Battery life (approx 5-10% per hour). Since i caught the culprit in my home netork I get less than 1% drain idle per hour:
"I had bad battery life on my S4 right after release. I tracked it down to Multicast being ENABLED on one of my Access Points. I would recommend logging into your routers and/or) access points and look for anything related to Multicast and Disable it (or uncheck it).
Granted this was for a totally different device (note that my Nexus 7 was NOT affected by multicast) but it certainly cant hurt anything by disabling multicast..If it does, just enable it again.
My S4 was using approx 5%-8% of battery per hour with multicast enabled...once I disabled it, I now drain about 1% per hour.
This took me almost 2 weeks to discover...keeping in mind that my S4 never connected to the affected AP. I use that AP for older legacy devices.....just having it on the network affected my S4.
Give it a try..if it does not work..enable it again."
PS..disabling Google location services also helped me slightly with a runaway battery drain.

FYI it is possible to retain root and take the update as explained here: http://forum.xda-developers.com/showthread.php?t=2504408 If you've already updated though you'll just have to wait for an exploit.
I have been hawkeyeing that thread all day lol...
To the OP: It's also possible you just have a bad battery... there have been cases of faulty batteries and some were even swelling up so perhaps you could try to get a replacement to see if it fixes it.

I'm seriously starting to consider that as well... I'm on hyperdrive now but it really hasn't improved that much. I'm currently sitting at 19% since 8:45 am this morning (currently 4:01 PM here). So I'm going to just dip over 8 hours today, sitting at work while on my computer mind you, which is still sad in my eyes...

Turn off Google location services, see if that helps. That was killing my battery on ME7, same as yours. If your not into rooting, the 4.3 update has fixed that bug, I'm back to 3.5ish hours of screen on time. I did give up root though, so pick your battle i guess.

I'm definitely considering that OTA w/survival mode... no doubt about it.
Today I was using Navigation for about 4 hours straight, GPS and location services on, with LTE, also using Bluetooth the whole time for music and Poweramp with some texting in between. I only dropped 35%. It definitely sounds like you got a lemon (either the battery or phone).
Wow, I am jealous... Yeah, I think you're right.
