Turn screen brightness down and check for wake locks using BetterBatteryStats.

Most likely, it's an app misbehaving.

Try using something like juicedefender lite or go power manager from the play store. They can help you set up different modes that toggle things that eat battery life. They also tell you what apps/hardware is using the most battery.
I found that on mine, the screen was using a ton as was the 4g at work (bad connection). So Juice defender will turn off/on my 4g every 15 minutes and download updates without draining my whole battery. Good luck!

you have an app keeping your phone awake alot.

How come NFC is waking up my phone when I have it turned off and frozen?!

The thing is I use the task manager a lot closing my apps and all. But it has not improved my battery life at all. And its frustrating since I'm out of the house almost the whole day (9 to 10 hrs sometimes 12 hrs). Should I change my kernel or something?

stop using a task manager. that is probably what is killing your battery.

Add this tweak to /system/build.prop
ro.ril.disable.power.collapse=0 - This setting puts your phone into a deeper sleep when on standby. This may improve battery life.
pm.sleep_mode=1 - This sets the phone to use power collapse when in standby.
0 - Power Collapse Suspend
1 - Power Collapse
2 - Apps Sleep
3 - Slow Clock and Wait for Interrupt (default)
4 - Wait for Interrupt

... Thanks that was really helpful. I still stand by Juice Defender. In areas where my data connection is weak (like at work) my phone is on for hours without dropping more than a couple percent.

there are many reasons that are responsible for fast battery drain.
1. App using the Processor to its fullest.
2. App misbehaving (restarting multiple times in background)
3. Overheating of device due to any external or internal factor
4. Battery fault.
I would recommend you
1. Set the brightness of your phone to "AutoMode"
2. Use Power saving mode while not playing resource hungry games.
3. Download Clean master. that will solve the app misbehaving problem which results in Overheating.
4. Charge your phone wisely.

Could you try the cpu temp notification, just turn it on and off like 10 times and tell me if you get any FC or if its not showing.
Thanks

Version 1.7
A lot of bug fix. Fixed governor settings not applying, added a check box to set governor at boot, fixed clear cache for ROMs that doesn't support it, fixed crash for CPU temp notification, fixed loop when device can't reboot, clear cache, etc. Added GSF id and System id info, (Will just show it to you).

If anyone get any other FC when enabling CPU temperature read, please report it again, since it should be fixed. Thanks.

New version with Rom management. Only available for CWM Recovery!!

I think you have a minor typo in OP 'turn off CPU 2' should be 'turn off CPU 1' as cores are CPU 0, CPU 1 (duel core) then CPU 2 and CPU 3 (for quad core device)

Yes I know that, but for not developers people seeing a number 1 is like the first CPU will be off. Since you normally start counting with the number 1. I did name it number 1 in one of the tests and I received a lot of e-mails asking me if its safe to turn off the first CPU and why I'm not doing it with the second CPU. So I decided to change the number so that way people wont get confused.
So basically you are right, but I did it on purpose.

[Q] One X overheating and not going into low cpu speed - Trickster MOD

Hi there!
I have 2 HTC One X, one of them is overheating in normal use and the other, with exactly the same use, is not.
I mean normal use by 10 minutes on facebook, 5 min on e-mail program, 5 min on internet browser.
Both have the same stock ROM version with Android 4.1.1, HTC Sense 4+, Software Number: 3.14.707.24.
During the tests they were not charging, almost same battery level and same installed and running apps. Also were purchased the same day in the same store. The only things that actually changes are the accounts, contacts and other personal data.
After use I have checked on Trickster MOD app to compare the temperature. And the Hot One X was really hotter, as expected:
- Hot One X:
Battery temperature: 42ºC Health: Good
CPU temperature: 52ºC
- Other One X:
Battery temperature: 35ºC Health: Good
CPU temperature: 39ºC
But, besides that, I saw something odd on the "Hot One X", it was not going into low cpu speeds.
Trickster MOD says:
Not Used States
51 MHz, 102MHz, 204Mhz
This explains why is getting hotter.
Also this is only happening on the "Hot One X", on the "Other One X" the Not Used States list is empty.
Here is a screen shot of the Hot One X:

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Also, comparing to the "Other One X", the 340Mhz cpu speed is much less used on "Hot One X", what means it uses more higher speeds. There was no lags on neither phone.
So my question is:
Is there any way to make it use also the low speeds? I mean, is there any configuration for this?
I think that maybe there is some way to enable/disables cpu speeds, or make a profile: uses more that, less that.
If that is true, how to do it?
Thanks

anyone have any ideas?

Anyone facing the same issue? Install trickster MOD free from Play Store and check your One X

Which governor are you using?

Both using "ondemand", but I tried "conservative" too and the same issue. Also I tried "powersave", but both devices became so so lag that I couldn't even open any other app (about 5 seconds to scroll down a page) so I selected "ondemand" again.
The overheat was happening on the Hot One X since the Jelly Bean update, even before Root Unlock and Trickster MOD. The Trickster MOD just helped me to guess what was happening.

tried factory reset already?
Reflashing rom and kernel might help
Or a simple RESTART might help too.

Yes, I've tried factory reset 2 times with Jelly Bean.
Haven't tried to reflash the rom, I'd like to use the original rom Jelly Bean or ICS, is that possible?
Isn't there any configuration for enable/disable cpu speeds?
Restarted several times using: turn off / turn on, restart from menu, turn off / hold power button for 20 sec. (slow startup), disable fast boot and restart.
Thanks

Any more ideas?

maybe you had mods installed on the other one? i had this before the cpu wont go down 1.5hz and then it over heats

Sorry, what mods do you say?
By the way, both devices were hard reseted and were installed exactly the same apps.
Isn't there any way to enable/disable cpu speeds? I guess it should be that somehow, maybe failure applying htc rom update.

Maybe mods like changing build props etc or sound mod or mods that changes framework my suggestion flash a rom without any mods then check and see if itll fix it.

It's a stock Jelly Bean rom, original, never flashed any other ROM. It's rooted right now, but the issues appeared before root.

Maybe u can try to flash new kernel or better yet flash stock rom again see if it still like that.

[APP] 'Data Lock' : unplug 3G while the screen is off

Hi
I'm not a developper but I created an app with the Tasker App Factory that unplug 3G one minute after you lock your screen. The one minute delay is here to prevent the phone plugging and unplugging at any time the screen goes off. During this delay, if you wake your device, the process will stop and begin again when you turn the screen off. When the screen is off, after the 1 minute delay, 3G is stopped while the phone is in your pocket to prevent battery drain
Once it is stopped, if you wake the device a new 5 second delay is started, for those who just want to check the clock , and then the 3G is plugged with a ''Data restarted'' toast
Note : Tasker IS NOT required to use this apk :victory:
Feel free to request any modification like the delay or the toast text, I'm here to share such things. And if it helped, don't forget the :good: button

cpu usage
Your app gave me a watchdog alert as it's using more than 50% CPU. This would counteract any benefits as eating CPU results in battery drain.
It also uses 15.3 mb of ram when its role is simple and in no way justifies the ram/CPU usage.

Going to try this as I am tired of manually switching to 2g all the time.

It seems to be using more juice than saving it.
Shows up as 2nd highest draining source after screen.

You seem to be right... That's too bad because I use tasker 24 hours a day with many profiles and tasks and it saves my battery!

very good.
i make a few sugestions
1. hide icon (dont need show icon, dont have config to make)
2. create widget or icon in notification to enable or disable
3. put in google play for updates
4. thats be good work in wifi too. or switch this option...

Thank you, but, you know, I'm not a dev, I just like the app tasker and they propose to transfer their context into apps. I'm absolutely not able to do what you're expecting (yet)

Verizon took out Battery Saver, here's Qualcomm's solution: Snapdragon™ BatteryGuru

I, and a few other users have noticed that Verizon decided to have HTC strip out their battery saver toggle on the Sense ROM (4.2.2) that ships on VZW's One.
Luckily, Qualcomm provides a standalone application which covers 90% of what the toggle does.
Snapdragon™ BatteryGuru
https://play.google.com/store/apps/developer?id=Xiam+Technologies+Limited,+a+Qualcomm+company
(personally, I haven't found the need to use it yet, but I figured it would help some people)

Thanks man, I was looking for that battery saver mode everywhere, but I guess this will do as well.

Thanks for this info. Anyone know if this is particular app will perform better from more generic battery extenders like Juice Defender?

According to the reviews all it does schedule syncing. Don't know how that is going to save battery...

Battery saver apps are a joke. The only thing I liked about power saver mode was that it cut the CPU frequency down and cut data off after a certain period of time. Other than that, if you need to save more just turn your brightness down, turn off bluetooth, use WiFi as much as possible, and use the phone less.

I normally agree - I realized the other day though, that I don't need background *push* email - but I'd like to have my phone "fetch" email every time I wake it up. Anyone know of anything like that?
(there is a manual setting, but it is when you *enter* the mail app, I'd like it to fetch every time I use the phone.)

Think about how often you "actually" need to have your emails and set it to that. For me, my Yahoo emails I don't need it to check but once hourly. But Gmail is push automatically so I won't mess with that. My corporate email defaulted to push but I often don't need it to constantly update and annoy me so I'm contemplating on 30 min intervals. Setting your emails to longer intervals should reduce that "email stress" that most people seem to endure these days.

The app has low power mode controls.
You can turn off mobile data during inactivity.
Some other features.
It basically gives you battery saver control on any Snapdragon based device.

Lol you could always just use BoneStock ROM. Andy threw the battery saver apk from (can't remember dev's handle. sorry) back in it.

It limits CPU, dims display and disables vibration feedback. Basically everything you can do yourself in stock and if you have a CPU app like SetCPU. Just a one click option that Verizon took out bc they hate battery life I guess idk.

Im running bonestock now, and the power saver has increased my battery life fairly significantly, i'll take that, because at first i wasnt impressed with the battery life, and i watched the ifixit tutorial on how to tear this phone apart to replace a battery, and i want nothing to do with that
