What is Music Enhancer service? - HTC One X+

Had the phone 4 days. Watching battery and monitoring tasks periodically using Android Task Manager.
Noticed 3 or 4 times phone got hot when I wasn't doing something. CPU was nearly maxed for at least 20 minutes. Battery dropped like a rock. I mean, the USB charge can't even keep up with the drain - battery still goes down while plugged into USB. Like 10% in 10 minutes. All times, the real-time process list showed it was "Music Enhancer" and "Sound Set" being the major contributors to CPU usage.
I was not playing any music or had any music apps open any of the times this happened. A day after I got the phone I transferred 16GB worth, 2800 MP3 files. It is almost like the phone is periodically analyzing my music library or something and just hasn't gotten through it. Total guess though.
I have seen reports of users of similar phones that they say there battery life got miraculously better for no apparent reason a couple weeks after they got their phone. Could they have also had large music libraries and there is some sort of periodic initial analysis that goes on..
Not info about what this is ANYWHERE I can find on the net. Trying to get a response from HTC.

Titan and battery life

Hello, I'm just wondering how long does your Titan last and how do you find battery life. I read all over the internet a lot of people very happy with Titan's battery, but mine is quite bad. I'd like to understand whether it's just my phone which has problems or it's normal.
How long does your phone last? Could you describe the average use you do during this time (do you have gps, bluetooth, wifi, push-mail and stuff on or off? How many calls, text messages, web browsing, games and such?).
Because I just realized that I can use it with all options on and xbox live and get from 100% to 10% in an hour and a half... Is it normal?
My Titan lasts two full days (around 48 hours) of normal use. I never use Bluetooth but wifi etc it always on.
Playing games drains the battery quickly so I often hook it up to power when I play gfx intense games.
Overall I am very pleased with the bettery life of the Titan. I get about the same usage with the Titan as I did with the Mozart. The bigger battery clearly makes up for the bigger screen.
Ok, games drain battery quickly, but less than two hours is too quick, in my opinion... That was why I was asking for other experiences. Thanks for your answer anyway.
I leave bluetooth and wifi on all the time, do about 2 hours worth of web browsing per day, listen to about 30 minutes of music per day, send a few texts, about 10 mins of voice calls and sync all accounts every hour, battery lasts me comfortably a whole day. HOWEVER if I am in a poor reception area for cellular, my battery life is significantly degraded because the phone is continuously hunting for a signal, this has been a problem on every phone I have ever owned including my nokia 3310!
Well, today I went out with 100%. I left gps and wifi off and 3G on. I listened to music half an hour, browsed the web for another half an hour, used Freda for reading a book another half an hour and then used othe apps with internet connection for ten minutes (no games though). After three (3) hours I was at 50%... I didn't see any lack of signal so I don't think that could be the reason. I'm not sure but I think there's something wrong with my device...
Since I couldn't find any difference before and after the update I don't think it's a software problem. Do you think that replacing the battery could be a solution?
Do you think this is a good reason to contact HTC for support?
Did you check the list of background tasks?
Maybe some app keeps doing something in the background, draining your battery?
Do you mean the list you find on options/settings->applications->background activities (or something similar, I'm translating from my language, maybe on the English version it's different)? There's only gmaps there and it's disabled.

Yes, that is the one I meant. How much battery life do you not get when playing games though?
Well, I just got from 90 to 80 in ten minutes. It's like games drain 1% each minute. This would mean around one hour and a half to get from 100% to auto-shut down... Now I'll see how it goes with playing videos...
I played with games for a little more than half an hour and got from 78% to 38%. So it's still a rate of 1% per minute... How is it for you?
For videos it lasted more, it drained around 4% for ten minutes of playing. I guess this is acceptable, or not?
I'd try not playing games or videos - just use it for email, some browsing etc... but without the intensive usage of games and videos. See how long the battery lasts then. Mine lasts for at least a day with normal use, sometimes up to 2 days if not used too much (although push email always on in the background, and some other apps with live tiles etc...).
Games do drain it pretty quick IMHO.
I think you should let the battery expose for a few more days and maybe there will be improvements like a break-in thing. imho, the battery is used more when playing games 'coz it needs more drive from the 1.5GHZ processor. As for playing videos/internet, it doesn't require much power from the processor and suppose that it doesn't even have flash so more conservation of power to it.
Today I haven't played nor watched any video. I used internet on 3G (marketplace and explorer, one mail in push), read a couple of pdfs and not much more (gps, bluetooth and wifi off all the time but twenty minutes). I unplugged it at 10am and at 5pm it went in saving battery mode (less than 20%) and I had to plug it one hour later because red blinking light was there. I had some doubts but now I would say there's something wrong almost for sure...

That is not good at all, I get way more than that, you may have a faulty phone.

That is very poor, I am getting great battery life and I have two email running all the time, facebook, twitter, using wifi, texting, internet etc etc. Get that battery replaced at the very least.
But I'm afraid it might not be just a problem of the battery, it might be the whole hardware which is faulty. I mean, i could buy a new battery and discover that it doesn't solve the problem, that would be a waste of money... Maybe I'm paranoid, but today I experienced even bad experience with phone calls, I couldn't hear the other speaking nor he could hear me and I had to call back three times for less than ten minutes of phone call. I read someone else had similar problems, so I fear it might be a faulty phone and not only the battery... But I haven't had other calls, maybe it was just a coincidence.
Just a quick survey. When you unplug the phone at 100%, before you start using it (without wifi, web browsing, application and stuff) how long does it say it will last? Because as soon as I unplug it I get a 13-15 hours, which aren't very much I think... Considering it should be considered almost standby mode...
Your battery will be covered under warranty by Htc, contact them and tell them the problems your having!
I did and they told me to do some procedures (like taking off the battery while the phone is turned off, or uninstall all apps or reset the device). I'm trying to do this things, if I can't solve I will call them again.
Yeah, that's their standard spiel for any battery problems. I would insist on a replacement handset - how long have you had it?
Hi!
I just got the Titan yesterday.
I haven't had to charge my phone since then! It came with around 78% charged battery. I've synced about 6 emails, 3 social networking with my phone. Downloaded few apps, games, plenty of text messages, couple of phone calls. I've also customised and changed settings etc. Did plenty of youtube and internet browsing. Played Angry birds for about 16 odd levels, played unite for nearly an hour. Today it second day of the phone and I've got 26% battery remaining. Haven't had to plug in the phone at all!
Oh I did plug in the phone for brief time. That's when I downloaded the recent update via Zune. The whole update procedure took nearly 15-20 minutes, so for those minutes my phone was connected via USB. I don't know how much charge or drain this installation of update and restart might have caused.
In a nutshell - The battery life is much better than those nice reviews on the internet.

Bigger battery capacity

Hi all,
I love the Sony Tablet except its battery life. for something that is so huge compared to the others similar products out there, I am sure that they could have squeezed a bigger battery into the unit.
The power capacity is pretty weak. Let's hope that Sony offers a higher capacity battery size. I would gladly pay to upgrade it.
That's weird, my battery life is fantastic. If I play games on it all day it'll last 8-12 hours, but if I just use it intermittently and moderately it'll easily last me a couple of days. On standby it only uses a couple percent a day if that!
I'm the same as unclespoon. Even during heavy use, I get about 9 hours, which is way better than my old Galaxy Tab could ever muster. Standby usage is crazy low, its fantastic!
Not sure what you mean either about being larger than most other devices. The Tablet's 9.4" screen is smaller than almost any other full-size Tab out there (including the iPad) and since the back curves, theres not actually a lot of usable rear space (look at how thin its getting at the thin end, now imagine trying to fit a battery in there!)
I'm not sure you'll find a Tab out there currently with a better combo of size/battery life. The chunkier Toshiba Thrive will last longer, the thinner Galaxy Tab's will last even less, and my Tablet S always outlasts my iPad, so it might just be your device. Try checking Settings -> About -> Battery Use
I'm of the same opinion as the op. My tablet s has dreadful battery life and especially when it isn't doing anything. (50% usage is system standby) my old galaxy 7 was far far better (charged about once a week)
I believe this may just be because it is new (only have 1 full charge) as my galaxy s2 was initially unimpressive and then lasted 3 days of moderate use without charge. Hoping the same will happen to my s1.
Time will tell
My only guess was that you did a shoddy job of conditioning the battery. My old Galaxy Tab (the first 7" one) was hopeless, but when I replaced it, I conditioned the battery better and it was a bit better.
My Tablet S lasts for days and days and the standby usage is tiny. Check whats using your battery in the Battery Use screen and get back to us, we might be able to help..
I noticed advanced wifi lock was causing massive amounts of wakelocks (8 hours out of 10 according to the stats in settings/about).
betterbatterystats is not available via market but I am trying out the XDA APK now

I noticed that as well. If you have Advanced WiFi lock activated the tablet won't go into deep sleep mode, there of massive battery usage. I still have Advanced WiFi lock on my tablet, but only activate it when I need to download/update something that takes time. Otherwise I turn it off. It's not worth the battry drain.
Wow. Your battery life are fantastic. 9 hours? That's huge. I have not used my Sony Tablet till flat but given the rate of battery loss think maybe the most is about 5 hours which is similar to what many reviewers are saying.
Just can't imagine that those reviewers are so far out of the ball park compared to you guys. I am using juice defender Beta. Not to sure if its helping or not. But at least if I not using WiFi it shuts it off automatically.
My battery used to drain badly during standby. I found that the Friend Stream service was preventing the tab from sleeping. Killed the service a while ago and battery has been fantastic since. Pushed it to 3 days with light use. About 3 hrs of browsing and facebook. My battery level is at 68%, been off power for 20h40 mins, and used for about 4hrs today - facebooking, Internet browsing. Note that no specific conditioning was performed.
What are the settings that you have on your Tablet? Auto brightness, background sync turned off ?
how did you stop friendstream, and what the heck is it, did you just kill the process and it stayed dead? (sometimes as u know u kill process but it will come back).
Good question. What is the Android software revision now. My is Android 3.2.1 (revision 2)
I acutally just uninstalled the crap-app. nothing I use anyway. It is an app for facebook, twitter and other social networks. So just get rid of it. Uninstall and be happy
my bad. I confused the HTC name and Sony name.
Social Feed Reader was misbehaving. Once started it kept running... rather than dropping off to sleep (and into Cached Apps).
Something wasn't right so I force stopped it and it stayed dead.
An additional note - the Setup, Applications, Running Applications feature isn't 100%. Some background apps aren't displaying as running or Cached. Go figure.
So any special method to stop the social feed reader?
I'm getting those kinds of numbers on mostly auto brightness (and sometimes lower, at night), with background sync turned on, WiFi sleep policy set to default, and no battery monitoring or saving apps running. The only thing I did was single initial conditioning cycle and since then its been great.
Also note that software-decoded video files will take a lot more of your battery than the equivalent properly encoded file. I havent had any trouble with Social Feed Reader, but I never even set it up and judging by the many stories around here, I would uninstall it if you're worried about battery..

Hi, that's good to know. Thanks for sharing. Unfortunately think I screwed up the initial conditioning. so I guess I will have to live with the 5 hour battery of my Tablet.
Btw how do you do battery conditioning?

In Setup, Applications, Running Services have a look at the awake time (listed on the right side) of the running processes. You'll note that system processes (the ones with the Android icon) have been awake since last boot.... but you might finds others that are as well. I noted Social Feed Reader showing high awake time and decided to nuke it. Simply click the offending app. You'll be given the option to stop the app... which is what I did. It's an app so doesn't restart once killed. Hope that helps...
Final thought: at the top right of the screen there's a 'Show cached processes' option.
The could be an offending app in there. Kill any installed app you suspect might be a problem and see if that helps.
my battery life is excellent.

Rezound severe battery drain

So, have my new rezound (old D2 r2d2 lost a fight with the driveway) unlocked and rooted, running 2.01.605.11
Display brightness is set to ~25%. Running on CDMA only 3G. Only auto sync tasks are my email accounts, and those are push updates (only get 5 or so emails a day). All other accounts and apps (weather, news, Fbook, etc, are manual updates when opening apps)
Yesterday i charged to full, wiped the batt stats in recovery, ran it dead and recharged to full overnight.
Unplugged around 7am and then gave the charged phone a bump charge to bring it up to full. Turned on the phone right around 8am. In just a shade under 4 hours (only 22 mins of which were screen on time), the phone went from 100% to <20% charge. Phone had signal 100% of the time, no roaming etc.
Yesterday i charged to full, wiped the batt stats in recovery, ran it dead and recharged to full overnight.
Suggestions? I just ordered a 3400mh battery, but still, I gotta believe something is WAY wrong here. I really don't want a huge battery that's still just gonna die in 6 hours....
Screenshots of relevant stuff attached
what the temperature u getting
if its not getting heat enuf i mean 45c
ur battery could be not good i guess u replace it
After 15 hours (7 am to 10 pm) of moderate use yesterday, couple texts, a few emails, couple short phone calls, 2 hours of listening to music at the gym, checking facebook couple times and I was at 60% when I plugged it back in to charge it. So something is definitely wrong with yours. Under Settings>Power>Power Mode I have mine set to Normal, I also turned off all animations but have all notifications and auto updates are still active and have weather set to update every hour. Set to CDMA only out of the box too.
Are you playing words with friends? How about any other ad supported apps like Angry birds? All ad supported apps are battery killers even when you aren't using them.

Proz - Screen's been off for like 2 hours now, plugged into a wall charger, temp is 43.2 degrees C. I disconnected it from the charger, and let it sit for 10 minutes with the screen off - temp went down to 40.3 deg C.
I've noticed high temps occasionally, especially if i'm streaming netflix while charging, or running screen at full brightness for an extended period of time. When it gets that warm, and I plug in to charge, the LED alternates green and yellow, indicating overheating, but after a minute or two with the screen off, and plugged in, it cools down and charges normally
kzoo - not really. The only apps I use are the yahoo fantasy baseball, and aldiko reader. The phone still has all the bloat on it, but I don't ever open any of those apps. Also, i do run advanced task killer before i shut the screen to kill programs and background tasks. I then exit out of ATK - I don't keep that process running on auto kill, as I've heard that when you let it kill stuff every 1/2 hour, those processes re open, and ATK kills them again, and that open/close/open/close cycle just chews up battery even with the phone off
i would replace that battery and ask for more info in post ur battery thread too
while only charging the battery should be the room temp'
that look too high

The fantasy baseball app could be doing it. That 71% display usage is high, are you accessing the fantasy baseball app a lot during the day or for long periods of time? And of course Netflix will be a big battery drain too as it takes a lot of juice to power this display for long periods of time. I get the same % display time that you posted on my wifi only Incredible that I play Words With Friends on during the day and my battery on the Inc only last about 6 hours when I'm playing it. My Rezound's display only uses about 30% for 15 hours but I don't play games or stream music or videos on it.
Maybe try uninstalling all your personal apps and see what kind of battery life you get just plain stock.
Edit: Are you connected to wifi or 3g when your doing all this?
I don't think it's the yahoo app though - i got the phone friday, and was dealing with the major drain all weekend. didn't install the baseball app on the phone till monday. No appreciable performance difference with the app installed and being used
also, i think one of my screenshot showed my screen on time - 22 minutes on, out of 4 hours, maybe 10 mins of that was on the baseball app, 5 on aldiko reader, and the rest going back and forth in my settings/app settings to double check that i had all the sync settings set to my preferences (i.e. push only on gmail, lowered brightness, etc)
Yeah then something is not right with the phone. I added some screen shots of my battery stats for today in my last post. With 9 hours on so far today, I checked email about 20 times, made a phone call and got a couple texts and played music for an hour at the gym and I'm still at 84% battery. I'm getting great battery life out of this thing without any tweaks.
cool - i'm going to wait and see what kind of battery life i'm getting with the 3400mh battery. If it only doubles to 8hrs, i'll know it's the phone and not the battery. If it jumps to like 16 hours of usage on one charge, then my stock battery is going to be on a one way trip to the scrap heap
i'll post an update in a few days when my new battery shows up
in the meantime, do you think VZW will give me a new stock battery if I go to the store and show them how hot this one is running?

It's worth a try and asking them for a new one otherwise they would have to replace the entire phone. I had them check my battery on an Eris a couple years ago when I had charging issues with it and they were ready to swap out batteries with me but it turned out it was the phone that was the problem.

[Q] HTC Desire X-battery

hello, my english is not so good but I hope that you will understand me, because I used google translation
can anyone tell me whether this smartphone too much battery consumption if I turned 100%, then:
surfed on the net ten minutes
played medium demanding game twenty minutes
Runtastic worked a 2 hour (GPS and mobile internet)
1 hour listening to music
and watching a series of half-hour*
at the end battery status was 60%
Otherwise, I noticed that for about ten minutes surfing the internet battery falls to around 5%, so if it's ok or not
Thanks in advance for your reply
I think that's ok. Just surfing the net does consume a lot of battery, gaming and watching videos as well.
Thanks,but since I'm new with android I thought that the battery can last longer
To preserve battery-
Turn brightness to lowest.
Turn off unnecessary app sync.
Increase duration between sync of weather and mail and other apps.
Turn off network data connection n GPS when not in use.
Uninstall useless apps which you installed but never use them.
sent from my HTC DX
90-100% of batter never gives right amount of battery, under 90% its much more precise
this battery consumption seems fine, apps like runtastic or google track eats a lot, games acctualy too (fpse is the worst, its like vaccum cleaner), movie player... dunno, i dont use them, but they wont be battery-friendly
Recently I tested a lot of my HTC Desire X, so I can say that I am generally satisfied with all, except that my surfing over 3G networks too quickly consumes battery (recent example: 20 minutes on Tapatalk battery drains about 10%).In the first days of use I even thought that the smart phone serviced(or maybe I should), but it seems to me that I have to get used to it, and use the mobile internet to a minimum.

[Q] Screen battery drain after update to 4.3, but weird one.

Hello, new guy here. Thanks for having me here.
Did a search for the issue, but none thread found comes close. I did an update on Monday (24.03.2014) OTA to 4.3. Of course it failed - forgot to do factory reset before that so what I got was famous samsung screen with blue LED on. Long story short, managed to recover. I had all the usual after-update-battery-drainage issues, but after tweaking and forcing shut a lot of stuff it is much better. Except for screen.
When I use phone with screen on, the battery level drops almost visibly. I would estimate it at 1% for 1.30 mins. What's more - when I use Google Maps Navigation in my car, the phone loses charge even when plugged to the charger (old trustworthy TomTom USB, rated at 1000ma). Slow - about 1 percent for 7-8 minutes, but still. Oh, and phone gets very hot then. With screen off (power button or automatic off after 30 sec) the battery life is awesome and it charges like a sponge. even with constant H/H+ internet connection, audiobook player with headphones on and of course phone services. Comparing to "before update" its much better. Of course it may be due to lot less freeware (read: adware), but it is better.
However, screen is a killer in this deal.
60 hrs uptime, 15h 15min on battery, 47% of it screen usage. Next is Device Idle with 13%. During that time screen was up about 5h total, of that 3h while plugged to charge. I also went through two audiobooks totaling 20 hrs, browsed net (heavy with the downloads - 3gb total) for 2h, used Kingsoft Office for 2h and navigated with google maps for about 4h, did about 3.5h calls, emails check every 10 min (just headers), some texts and camera. All times approximated, but fairly accurate.
Phone is 1,5 years old, is and always was stock. Bought in UK, used in UK, locked with H3G (Three).
Does anyone have some advice? Tips? Tricks? suggestions? Much appreciated.
Thanks,
Adam
What you have is normal, you need a new charger is all and probably a new battery. 5hrs screen on time from a full battery is the best you can expect..

Thanks for quick reply.
Well, since my SGS3 is 16 months old I would say that max screen for me would be bit less than 4h. Battery was used and abused (had message about it being too hot for charging a few times etc.), but right now it is more like 2h on scree time. And NOT charging while navigating is new. Started right after update. And this not charging issue is of supreme importance. I've a roving job over quite large area so I'm driving a lot. And sat nav is a must. And since it's draining battery even on charge it worries me as phone is used extensively - technical chats, calls, online and offline documentation etc.
Anyway, will change the charger. Battery... Have half a year till end of contract, so will think if I need the expense.
Oh, one more thing. On Monday my SanDisk 32gb SD died - that's why I updated. Wasn't sure which gave. I had unexpected unmount message with this card. Could this issue use more battery as well? different card now.
Thanks again.
Sd card issues will drain battery. Charging stops when the battery reaches 50°C so if you are navigating and don't point an air vent at the phone it will overheat and stop charging.
Batteries last six months before capacity is reduced, after 16 months you will be lucky to have 50% the original capacity, less if it has ever overheated.

Oh, that I know. I'm hard on batteries, but not in phones. None of my phones ever had failed battery pack, but laptops... all of them. But that's not the issue.
Battery is essentially low energy chemical reaction, so obviously it will be degrading. No issue there. That's why I'm not shooting for max parameters and not worried about it, especially since update phone lasts more. Waaay more.
I changed chargers and it's the same (I have two more never used TomToms and one Tortoise rated at 2 Amps). So i'm starting to think that the issue is not batter, charger etc. I think Google Maps on navigation (which uses simultaneously Screen, GPS and internet) also goes on max on CPU and GPU. that's why tere is overheating and not enough power for everything.
So it looks like software issue. Google maps in particular. Do another factory reset? Everything is up to date. Or maybe I overlooked something?
Partial solution found
Hi all,
Sorry for late update, but was out of the country and all that.
Thanks for suggestions. They were useful to solving most of the issues.
First, changed cables, not chargers. cleaned also contacts in the socket of the phone, so battery gets charged well and fast all the time. And is even better after couple of cycles of full discharge/full charge.
Probably because of having less "apps for free" it is simply phenomenal - normal sync (incl. emails), normal gsm, heavy music listening - takes about 5-7% of battery charge per hour, depending on signal strength. It is much worse when working with screen on, but still good - about 5-6 hrs of gaming for example.
There is still issue of excessive battery drain while using google maps, but this may be software issue. will be uninstalling/reinstalling it soon. Should help.
Will inform on that one as soon as status changes.
