[Q] Battery Issues / Questions

I read through quite a few of the battery issue threads but would still appreciate specifc advice on the issue I am having with mine.
I already couple times did the stats wipe as per the tweak guide on OT site but do not seem to have any benefit from doing it.
I am encountering the following issues:
Charging
Charging is very finiky. If i am charging in operation or while turned of the tab will seem to stop charging at certain levels of charge between 70% and 95%. If it happens while charging turned off I need to disconnect and reconnect in order to coninue charging, sometimes a few times.
If it happens when in operation similar will happen but also when the charge is reported at 100% I tun off the tab only to find out that the charge level reported by the off battery icon is not 100%. On different occasions it displlayed anywhere from 80 to 95% (estimated). Dont remember ever seeing it at 100%.
Discharging
If I turn on flight mode overnight I will get almost no discharge all night 0%-1% which seems very cool but my normal use is really wireless thethering. I just started not even 10 minutes ago from 100% charge and already at down to 90%. Just playing a game or browsing or reading the forum using the XDA app can completely discharge the battery in less than 2-3 hours. All of this in spite of the fact that I am on Jupiter, UC and UV heavily. I also manualy been stopping running services like skype and yahoo messenger.
I am afraid this could be a a battery hardware issue but would appreciate a confirmation or a suggestion of what else I can try before restocking and going to the service center to get the battery replaced.
Maybe you could advise which system apps I can freeze with Titanium and still be able to maintain wireless tethering and phone functions. Maybe an advice on a task killer and what I can and can't kill to keep the mentioned functionality.
While writing this post I lost 8% charge!!!

Dont get any task killers they kill system process then the system has restart them which kill battery. Have you tried wiping batterystat.bin when below 10% and charging to 100% while powered off.

Or try backing up data and restocking and installing the WIPE version of
Jupiter or of kratos.

thanks mate, I always restock and do the wipe version. currently on Jupiter and will soon be moving over to Kratos. Reading good stuff about it.

The only way I would install a task killer would be if I could get someone to tell me which tasks to ignore so I wouldnt get this issue. No have not tried the below 10% wipe but will do so since you mentioned it. In the Kratos thread somebody mentioned to let it completely discharge and then without connecting to boot into CWM and let it further discharge. Aparently a system full discharge is not a full discharge and there is another couple hours juice left in the battery to keep the CWM going. Would this be a good idea?

Thanks to the helpers and to all you readers I think I found the issue. It seems to be a hardware problem but not with the Tab. The problem was with the charger.
I accidentally came across a car charger, bought it, used it to partially top up a couple times in the car and right away the Tab seemed a bit different. So I went back and bought a mains charger plugged it in last night and for the first time in quite a while it charged to 100% and it happened within expected time. Put it on charge at 1.30am and it was at 100% at 5.30am when I woke up.
Dont think it will effect the drain much but it is definitely giving me more juice to start with.

Oops!

After running Kratos for quite a while with my new chargers and recalibrating by the book I am getting the expected level of battery juice. The tab charges efficiently to100% every time.
Drain is still an issue for me though. If i set airplane mode overnight (8hours) it will loose 1% charge but 9%-10% without airplane mode. On standby and in use the drain is consistant and fast. Not even UC and agressive UV helps.
I did a lot of app freezing and it realy doesn't make a major difference. Normaly I have only 4 services running. Settings, Google Services, AnySoftKeyboard and Google Maps.
I don't think I had the same drain on Hermes even though i didnt UC, UV and had at least a dozen services running. Think my battery life was better while others were complaining about wifi reconnection issues. ASAP I will try going back to Hermes to either confirm the issue with Jupiter/Kratos or to just accept this as normal and shut up.

I finaly narrowed down the battery issue.
When on wi-fi i will get up to 3 days of battery life but only up to 16 hours on 3G.
It has been suggested to change the modem. I am curently on JPZ. My GT-P1000 was originaly purchased in Saudi and currently, until my next contract who knows where in the world, using it in Croatia.
A suggestion on the most battery efficient modem that works globaly would be appreciated.

FYI - Kratos Overcome ROM has(or had, there's a new one out today and it might fix this?) a bug with wifi where that if you leave the network and then reenter it without manually turning off then on the wifi, it will constantly reconnect(or something) and burn battery like mad.
For now I just flip the wifi off/on again when i connect to a new wifi since i didn't want to leave Overcome. Hopefully the new one fixes it.
---------- Post added at 07:05 AM ---------- Previous post was at 07:04 AM ----------
and by leave/reenter network, i mean physically walking outside the network range until it disconnects, not disconnect/reconnect through the tab settings.
It may only happen moving from one network to another (i go from home wifi to work wifi to home wifi each day).

Mate thanks for the reply but think you misunderstood. I dont have an issue with wifi. My issue is with 3G/mobile network over SIM card. That one burns the battery.

So to understand what you are saying explicitly.
At home I connect to WIFI -- XXZ.. Its already a remembered network. I drive away from home and come to office here WIFI is YYZ (Already remembered network). So it automatically connects. THIS CAUSES the batt drain????
If yes, I am extremely happy. Coz I dont turn off WIFI it connects at home n office automatically. Please corroborate!

> I finaly narrowed down the battery issue. When on wi-fi i will get up to 3 days of battery life but only up to 16 hours on 3G.
I think that is normal standard consumption. 3G is known battery hog and you cannot compare its runtime vs. wifi. Is 3G on all the time, or maybe you attempted to use interval disconnectors (ie. battery saver apps) like JuiceDefender, Green Power, the likes?

Thanks jtdc!
I move around the world a lot and rarely set up wifi so most of the time I am full time on 3G. I dont use any power saving tools like you mentioned. Insted I use Titanium to freeze any apps that unnecessarily show up in running services.
I only noticed the differwnce with wifi due to an exteded visit with a relative who has wifi in his house. It wont be long and I will again be full time on 3G and would realy like to extend the battery life by minimum 4 hours. Are you aware if there is a known difference in power consumption between different modems or if any of the tools you mentioned can deliver this kind of savings purely by managing the 3G operation?
Sent off the Blue Marble using GT-P1000 on Overcome 7, v4 via XDA App

if any difference of modems that would be minimal to negligible. what always comes as the factor is the strength of signal and of course the tab which always scans for it whenever you're on the move. what you experience is typical, and in best case good because 16 hours on 3G always on? your battery and tab must have been setup really well.
if you can bear with interval disconnector apps like i mentioned, it would increase your runtime. for instance you can have the app connect every 15 minutes to 3G then be online for at least a minute to have all your internet dependent apps sync (email, messages, news, etc) and have traffic threshold detection in case in a minute some transfer still ongoing, then maybe 2 minutes is long enough. then for the next 15 mins 3G is off, then it will repeat the cycle. in that manner there's quite a lot of power to be saved and will definitely extend your runtime.
if really no other choice, i suppose you need to buy an external battery solution, the likes of energizer xpal, so you won't have to worry about battery life.

Great, thanks, that solution is acceptable for apps that require data services. Can you recomend an app to use for setting it up.
I expect it would prevent me from using inbound calls via Skype but how would using such an app impact incoming sms service and voce calls? Would they come through and would voice call quality be impacted.
Sent off the Blue Marble using GT-P1000 on Overcome 7 v4 via XDA App

"Green Power" in android market does the job and its free, that takes care of data connections (wifi or 3G) and will not tinker with the GSM radio, therefore sms and voice calls are untouched. The other app "Juice Defender" you can customize even to turn off the GSM radio, even downlclock the cpu, etc. which will result more savings but is a paid app.
Let us know how that helped to increase your runtime

[Q]Battery Life on LG O2x, how to make it last long?

Hey guys, just got my O2x a week ago and its great. It was flashed with 2.3 and at some point I tested updating using LG Suite and I went to 2.2.2
Anyway, just asking if how long do your batteries (stock) last? Tested mine about 3 days ago and within a day it got drained. Just using browser and played some music and that's it, no Youtube or heavy games or whatsoever. Already rooted my phone and removed everything that LG has there except for the keyboard, Suite, Mobile Support, and Home Launcher. Still, same results. Please help!!

I have been using the free version of juice defender and that has help my battery a little so I now cab get a good couple of days out of it. The free version only really stops data when the phone is locked but it seems to work quite well. I also installed juice plotter to see when my battery gets eaten.

Thanks will do that. So basically battery drains more if mobile data is on? Haven't really experience that on my old phone (which is not Android OS).

I had to charge mine every night and sometimes 2 times a day.
Now, on a GB ROM, and with mobile data OFF, it last for at least a day (24h). This is with WiFi on (when awake of course).
Install a widget to quickly turn on/off mobile data, and only use it when you need. Then your battery will not drain that quickly.
Sorry for my bad english
My battery "record" is over 2 days Well, actually allmost 4 days, but then I didn't have WiFi on neither..

Mobile data is the killer only for badly done apps. Things like fb and twitter that sync every hour etc. Make sure when you install every app you check its sync status. Make them as infrequent as possible
Also try see how low you can get the brightness. Mine stays at 30% until out in the sun (have a widget to up it).
Remember even if not using your phone at home etc to switch tho wifi on as its much better
On good days can get 30/40 hours between charges when low use
Sent from my LG-P990 using XDA App

Worth to mention is that to get the less battery drain from turning on the wifi you have to turn of the data. Some people forget that and leave both on making it a double drain.
My only tip that I have that I know works is use it as little as possible. Turn off every thing that's not needed in the matter of syncing.

I'm no expert but is that right? All of the data goes through the wifi when on and connected so data connection is irrelevant surely?
Sent from my LG-P990 using XDA App

Thanks for the input and somehow, I can feel the effects now. Also put LBE Security and turned off most mobile data permission on my apps and even if my Wifi is on, not much of a battery drain but at least it has less loss.

i think that 1day is the real time of this battery with 1charge...intense use...

Yes when wifi is on data is automatically off.... You cannot have both on...
Wifi is no very power consuming when it's connected idle to a network, but think to turn it off if no hotspot is there because network scan drains a lot.

LOL.. anyways, i use juice defender. It does help somehow.

I have a same problem. Using my Optimus with MIUI ROM (Gingerbread 2.3.5) i only have 7 hours.
In my opinion,turning off all data connection to improving battery life, it's not a good idea when we choose Android phone.
So?

O_O My phone came with v20c 2.2.2 and had no issues, ran 3days per charge. Wish I had backups of original ril and BB for they were 100% on any I've tried since going through a bunch of custom roms.

I get 10 hours of *idle* time with 3g enabled. With Juicedefender things are okay, I almost always make it through the day and sometimes even 2 days when I'm not doing anything, but the battery just goes nuts if you use it. Sometimes I browse the web for a minute and bam 5% is gone, and I'm thinking to myself "what the hell just happened?".
You have to be very careful with apps that do not close properly. I discovered that Spotify was draining my phone like crazy and causing it to become very hot (draining it even faster, heat = dead battery in no-time) with no way to prevent this other than uninstalling the app. Then I installed a beta version of Spotify from their website and all is well. AccuWeather also goes nuts sometimes but that's resolved by deleting the widget on my home screen.
I run the latest nightly of CM7. Battery life seems to be about the same as the stock ROM for me. What's interesting is that active 3g data use drains the battery more than playing a game. I can play emulated PSX games for about 5 hours straight on a full battery with data controlled by JD.

Everyone should try the latest rom v20e (or the derivated version topogigi's rom). For me, it improves battery a lot! I don't even use Juice defender (and some people said it worsens battery).

v20e
yes Im on V20e and my battery is preety good !
Almost 2 days and I write almost 100 messanger/day and always wifi on checking emails,fb and more !

Hey guys, haven't posted since testing for about week, I guess...
Anyway, battery seems to be ok now. Juice Defender and Plotter works great, plus now on sleep, it just drain 1% per 2-3hrs or sometimes nothing at all, and its not SOD thats for sure.
Also tried Battery Calibration, it worked somehow also so with lots of messaging, wifi, FB, Tap Sonic, plus downloading torrents, lasted 24hrs in full charge with constant use.

2g + Wi-Fi drains the battery much faster than 3G + Wi-Fi for me. Both have a good signal strength.
Anyone know why this is?

Batery Usage HELP!!!!

I am currently running 5.7.893 rooted and I have been having battery issues lately. The problem is I sit here , 1h 37m off of the charger and the phone is reading 80%. The breakdown looks like this:
Android OS 39%
Maps 12%
Display 11%
WiFi 9%
and a couple other small things.
It seems like my phone is never going into standby and I can't figure out why. I've checked a bunch of things and no luck. If I click the chart at the top of battery info, I see "phone signal" taking a constant drain on the battery.
The only thing I can think of to do is to factory reset the phone and see if that helps.
Any ideas?

I would recommend the Factory Reset. But first, is there a chance it's a battery calibration issue? Have you checked the actual mV reading with an apps such as Spare Parts?
Before you do the reset, make sure the Backup and Restore are checked in the Privacy setting. And then after the reset make sure you check the two options presented about Backup and Restore. These show during the new setup after you enter you gmail info. Also, if not in a 4G area, if possible connect to wifi before you finish the setup as your apps will start downloading automatically. Good luck.

I did try battery calibration first without luck. I just did the factory reset and I'm charging to 100% now. I haven't done the titanium backup restore, because I want to see if installing the apps I use from scratch again will fix it rather than just restoring them.

That's a good idea. Lately I've been letting Google install the apps and then I use Titanium to only restore data to select apps (such as Tapatalk).

Well, now I'm confused. I haven't installed any apps yet after the factory reset. after 2h 50m of just sitting there, it's reporting:
90% still
32% Android OS
20% phone idle
16% display
16% cell standby
10% wifi
looks much better, but does this look right? I would have expected cell standby to be the dominant process.
wifi

Having the exact same problem. Seems to be draining battery at the same rate it was before the update (which was supposed to fix battery drain or so I thought). I'm-a try a little experimenting before doing a factory reset (HATE doing them). Right now, I'm theorizing the built-in Google backup process might be responsible because I've never seen so much drain before and I usually turn Google backup off since I use TiBu but forgot to disable it after the update.
In the meantime, I've prepared myself for the battery issues by purchasing the battery dock and an extra battery for three total. Swapping batteries is better than staying tethered to a wall charger so much.
EDIT 1: Looks like that did nothing. Next, I'll try wiping cache (didn't do this when I updated)
EDIT 2: Looks like not much change from wiping cache. Guess I will be trying that reset.
EDIT 3: Looks like I use the phrase "looks like" too much. However, the factory reset appears to have resolved the issue, at least initially. Fired up the phone and Android OS was only 8% of the battery usage after 10-15 minutes. Will check back if anything changes.

Disable push sync on your device.
changing and controlling your sync settings will solve your standby issues and improve your battery life.

I think a better way of looking it this is that your phone isn't spending 32% of its time using the Android OS and only 20% of its time being idle. That's just how much battery they are using. Your phone could be spending 3 hours "idle" and only 15 minutes using the OS and this is how it could read. It's just how much battery each one is using, not how much time each one is spending doing that particular task.

I'm with noosympathy on that one.
A ROM will improve better life but not that much... maybe if you ran it on 3G only, but then again, that is a maybe.
A lot of your battery is used when your phone is syncing.
When connected to 4G, it uses a lot of power trying to get a signal as well.
To help get some more life out of your battery, disable push syncing and notifications.
I set mine to 1 hour because I don't like being bothered for stupid bs.
When your in a place where you know you don't get 4G, turn it off. It is going to try to aquire a 4g signal while running on 3G the whole time draining your battery.
If am out and don't need 4G, I turn it off. It only takes about 15 seconds to turn it back on and have it link up.
Do you really need to be on 4G to play angry birds?
I recommend installing tasker. You can program stuff like this into it.
Sent from my Xoom using xda premium

Maybe I'm weird, but I don't have a need for 4G data all the time. 95% of the time I leave it turned off and battery life is quite nice with the Bionic just riding on 3G. If I'm in a situation where 4G would be useful I'll manually turn it on. Battery life is so much nicer when the radios in the phone aren't constantly fighting for supremacy.

Call it as you will. I leave data off unless I need it for something and when I do use it I only use 3g. Most of the time I'm in a wifi area so I'll just use wifi. Speaking of wifi I leave that turned off also unless I need to use it then I turn that on for the time being and turn it back off when I'm done with it. Other then that I use my phone mainly for texting, and calling when need be. If I'm home I use the home phone to talk, and when I'm at work, I use my cell strictly for text and if you really need me I'll talk to you by office phone. I also leave gps off. I see no reason to leave it on. I tried to post a pic of battery life yesterday but it would not take for some reason.. Like I said. You can call BS all you like. I know what my phone did for the last 30 hrs. Last night I charged it. Downloaded a few apps, and updated some app and played angry birds for awhile last night before I threw it on the charger. Maybe that charge was a fluke. I dunno, but that charge was honestly what I had. Pretty sad to sign up to a forum, look for good info and also try and help out someone else with this phone and give insight and then be called a liar by other folks. Maybe I just won't post anymore. Hope you all enjoy your phones and ROM's. I'll just tend to myself.

Droid 4 battery issues...unbearable.

I spent a few hours looking through other threads, but nothing seemed to quite fit my scenario.
Stock droid 4 with the latest over the air update.
I use the phone very sparingly during the day, and my battery drains very quickly...
Usually take off the charger around 8am and battery is below 20% by 2pm.
My usage is usually one or two 5 minute calls, and probably 10mins of facebook.
Is there a good smart action I could try?
I had one that turned off the 4g while the screen was off, but it made sending picture messages unbearable...
My battery use indicator blames screen, then OS, then facebook....
I feel as if it's not reporting the culprit correctly...
Any help is much appreciated.

I've had similar issues, not sure what I did to cause them. When I first got the phone, 16hrs+ with what I would consider moderate usage was normal. I've flashed AOKP and the battery life is back to normal (on track for 15hrs today), but the stock rom is a disaster.
I'll let you know what I turn up (if anything), but I have a feeling I'll probably be wiping everything out since I actually like the stock ROM (plus no hw accel in ICS).
Edit: Also, how did you have a smart action turn 4G on/off? I was under the impression we can't control that at all, except via system menu. Is a downside to VZW's 4G...

I believe that was actually via the app Juicedefender.
even with it on i was still only getting about 8 hours...
I am semi interested in rooting/flashing a rom etc, but my last experience there was a disaster(thanks to a ****ty droid eris)

I disabled all widgets except for facebook, being that it's the only one I use...
The only non essential apps running all the time are battery circle, and facebook(widget i guess?)
I'm now charged to 100%, gonna see where these changes take me.

What are your settings as far as Brightness, Haptic Feedback, Screen Timeout, Vibration (Incoming Message/Call or End Call). Also, I recommend just using the FB app instead of the widget as I notice most of the widgets draw power even when the screen is off.
I am currently running Eclipse 1.3.7 w/ xrjxMod, Brightness all the way down, all vibration and haptic feedback is off. Since I am rooted I also used ROM Toolbox to adjust my scan interval to the minimum. I have the screen timeout to the max, but I always turn it off manually after use. I am constantly on either FB, XDA, txt messages or the occasional game/Netflix use and with the exception of watching a full episode or movie on Netflix, I am averaging about 6 to 8 hours on a full charge.

My battery is now sitting at 46%.
Since my last post I used the phone for 18mins of phone calls and nothing else.
The breakdown is 46% voice, 23% android OS, 12% display, 9% phone idle, 8% cell standby...
The brightness is as low as possible, haptic feedback is off, phone is set to vibrate(thats the only way I get calls)
All three location settings are on....Should I turn them all off? I dont know which are important...

I agree with azreal. Check your setting. Haptic feedback sucks up juice and unless you like it is more of an annoyance imo. There is an option for it in language and keyboard as well as in the screen menu for your soft keys.
Do you have your gmail setup to constantly sync? If its not needed un-check it in you accounts menu.
Are you leaving wifi on when your not in range of a remebered router?
If you are not in a strong 4g area set it to cdma only in your wifi and networks menu.
My opinion of apps to extend battery life is a negative one. Its an app that always runs to make things stop running???? Some work ok but most do not.
If all else fails I would suggest the eclipse rom for the d4. As long as you are safestrapped and follow directions properly you can't go wrong. In the case of a bootloop shut the phone off and reboot and you will come back to the recovery screen to try it again or go back to stock. Its nearly foolproof.
You may also want to do a battery stat wipe if your still having issues. Just discharge your phone completly, then fully charge wipe stats and completly discharge again then fully charge once more, and see if you notice a difference.
I get around 15-16hrs on stock and up to 22hrs on eclipse (varies with usage) by following these few things.

I have 4g almost all the time.
I use a gmail, but I cannot find a way to limit it's syncing...I still want it to check for emails, I guess just not as frequently.

I would hazard a guess that having 4G on all the time is one of the main culprits. I leave 4G off unless I am browsing the web, forums, or something else where the extra speed is nice. I use the 4G Toggle widget from the market to turn 4G on and off. I always turn it off before hitting the power button to turn off the screen. No need for it to be sucking juice when I'm not actively using my phone.

I just installed the toggle switch, I'm gonna give it a go.

To turn off the gmail sync go to accounts click on you tap the account. Then uncheck the sync box.
When you want to check your email go to the gmail app hit the menu and sync. Takes about 30 seconds extra but saves some battery.

I'm always skeptical when people blame gmail sync or 4G on battery issues. When the phone was new on stock, and on ICS now, I have three gmail accounts, a yahoo account, and one Exchange account all syncing in the background + 4G on 24/7 and getting around 16hrs of battery life. This was the case for weeks. Then I started having trouble with Verizon's Backup Manager, did a factory reset, and now stock battery life is ~ 8hrs, with 4G OFF
I'm thinking at the very least, there is an issue with the stock battery information panel. My feeling is it hides battery use by the stock bloatware...

I agree that there is probably more to it than just 4G or syncing. Especially where people are getting only 8 hours or so battery life. I personally have noticed definite battery savings with 4G toggled off when not in use though. I can usually still go most of the day even with it toggled on all day but with 4G off, except when I actually need it, I usually get to bed with 30% - 40% battery left as opposed to 10% - 20% left with 4G on all day.

I would also turn all 3 locations off. No need to run the gps when not using navigation. I keep my 4G on as I use it frequently but I am going to try the toggle as well for the extra savings on battery when not netflixing/browsing.

Yep. I'm also having big issues with my Droid 4 battery. First I thought it was the firewall. But even after uninstalling the app, the drainage is absurd. The battery drains so fast, the phone gets warm.
I don't know where to look. I read something about logcat in another thread but could't find it anymore.
My Droid 4 can work about 5 hours on one battery charge. No gps, no 4g and no wifi. If I turn on wifi, it lasts about 8 hours, so I'm suspecting that some process loops when in non WIFI mode.

If you're out of options try using an app called watchdog. It let's you see if there is an app that's draining your battery unusually fast.

Thanks for the tip. But what whatchdog should I use? There are many apps called watchdog

Watchdog task manager lite (free version).

I tried that this morning. Still poor battery life on stock, but watchdog doesn't flag anything. Very weird
Oh well, I would definitely recommend AOKP for anybody having battery problems.
For me today: 4 hours 55 minutes since unplug, 80% left.
Screen time on: 50 minutes (!)
That being said, I do keep my screen on pretty low. Still, you can tell I've been using it...

Watchdog couldn't help me but. My data monitor showed that motorola.services was generating a lot of data the past few days (800+ MB :O ) and responsible for the battery drainage. I blocked it with droidwall. It's better now, but sometimes it still pops up and generates data despite the fact it's blocked.
So glad that I have an unlimited internet plan or else I was really screwed

[Q] battery issues - 3 charges most days

Hi everyone,
I brought this wonderful phone (or atleast i thought wonderful) couple of weeks ago ( delivered on release date)
Now i expected the battery to be good as its 2300 mah but it the phone doesnt seem to last no way near as long as other claim i had an s3 before this htc one, 9 times outta 10 i only had to charge it once a day and never activated power saver mode,
On the htc one i constantly have power saver turn on and it just doesnt seem to be doing anything , i havnt changed my usage of my phone, if anything ive used it less,
For example the s3 lasted my full 8 hour shift with nothing running expcept the tunein radio app, the htc one only seems to last 4-5 hours with everything closed except the tune in radio app. Ive not changed networks so low signal shouldnt be causing the drain as there isnt a difference in signal levels,
So is there anything else i can do to stop bettery draining. Bluetooth, wifi, nfc, etc all turned off, screen on auto brightness ,
Sent from my htc one with just 26% battery left and i havnt even rrached 4 hours of my shift yet, left house at 9:45 with 100%

You probably have an app preventing the phone from sleeping. There are loads of tutorials on how to check for partial wake locks to fix this.

Try this or this to detect the wakelocks. For more info on wakelock, read this thread

Definitely sounds like you have an app which is preventing the phone from sleeping and you should be getting a pretty easy 1 day out the battery at the very least in moderate use.

How have you TuneIn setup.
As general when you press pause rather than stop, itt continues to record that station and is always active. Iif you go into the app settings and turn off 'autostop recording' which should be defaulted to 8 hours - turn this to never and try again to see if it improves. I've seen TuneIn eat battery life on other devices where ths happens (people thinkits stopped when its just paused and recording away in the background...

That's possible ^^^^, however if he was just to hit exit on the app it should stop the services. That and really want to be sure, swype it away in the multitasking section.
Can try Betterbatterystats in the play store as a lot of people rave about that.
Also make sure Google Now is disabled. It sucks battery life like no other. Awesome tool, however to much drain on the battery.

Would be great if you posted a picture of the battery use. You must have a wake lock.

Guaranteed that you have horrible wakelock issues. Rogue apps, bad settings, and anything in between could be the cause.

I can go to bed with the phone fully charged and, 8 hours later, wake it up to see it's still at 100% (mobile data, GPS, WiFi left active.)
Once I'm bored of constantly picking it up and playing with it (i.e. get back to standard usage patterns) I get the feeling it will likely run to 3 or more days between charges. Won't be this month though

The Same happens with my phone.
The battery is really good. It feels like it is the battery time of my Onex x3

Well there are various reasons for this..Maybe an app that drains much battery not leaving cpu to sleep.You can download better battery stats and see the wakelocks and the cpu states that your cpu runs on.. You may also need a battery calibration.It will not increase the battery capacity of course but it will eliminate the faulty battery stats bin that tells the system the battery percentage.You may have for example 25% battery left and your device may show 2% or even close.
I assume that you do not have wifi always on, screen on for hours or using mobile data..The consumption of battery is huge.

how ? when u first got the phone ? did you turn it on or did you charge it?

Worth dialling *#*#3424#*#* and doing the battery test, although as everyone else has said it's more than likely an app.

I had a sgs2 over 2 years,rooted and optimized in battery usage, i was already happy. Now with the htc one it's a completely new experience....already now after a few days,with root but still no tweaks i get 60% left at 11pm!before the sgs2 was empty...can't wait
For fiture developement!!

Download Better Battery Stats, leave it for a day and then upload a screenshot of your wakelocks. My battery is easily lasting the day (ended at 11pm at 76% yesterday)

Same-ish problem.
Hey i'm having a similar problem,
I bought the HTC One (silver, 32Gb) A couple of days ago and the battery isn't even lasting a day with what I'd say as Medium/light usage. I do leave Mobile data on so i can get Skype/Facebook/line calls ect instantly, but i assumed that's normal.
I just left my phone alone for an hour with the screen off and it lost 4%, could this be a battery defect?
Are you telling me to get over a days usage, i have to leave mobile data turned off and only turn it on when i want to use Skype ect?
I saw a post above that one guys gets 3 days of usage with Mobile date, Wifi, etc all turned on. Is this the norm, or does he have a super hero battery?
I see the general consensus is to download "Better Battery Stats" and send pics of wakelocks, but Is there comparable app for free that will do the trick, as i don't have money currently on my English account.
Thanks to all those taking time out of their own lives to help others.
