As the title say, the screen is consuming 53% of my battery, i've tried every single thing and it didn't work.
Here some info about my device:
ROM ICS Pure 7.1 by Spike
Siyah v3.0b7 Kernal
Active widgets: Beautiful weather for weather/clock no animation activated tho
And couple of other widgets (Playstore - Tapatalk - Calender ) Others are just normal icons/shortcuts
Battery calibrated after ROM installation
Today my battery went down from 100% to 50% in just 7 hours of soft use, couple of calls/SMS and games for around 15 min and that's it!
Auto brightness, Wifi OFF, 3G/Data packet OFF
Also i'm using Juice Defender ultimate.
Here is some screenshots.
What's the display on time?
I've tried to use Jd it's a waste of time buddy.i had paid version to. here are some tips which i successfully use: 1 use dark (black) backgrounds for everything including your home screen- this I'd the biggest Batt saver on amoled screens anyway. 2 don't have notifications/active widgets on (they use processor etc)
3 if you really want Batt life increase think about an extended Batt -i have a 3500mah in my gs2. 4 don't use juice defender or any app killers .these things run in background and use processor and Batt. I've been using these procedures and they do work. hope this helps.

ps the screen using most showing most Batt usage is a good sign - it means everything else is consuming less Batt. but your post is a little worrying concerning wat you said 50% Batt. rogue apps are a problem that run in background. or the other major Batt killer is Android OS killing Batt in singer phones. try to look out for these 2 things.

The screenshots do not show under which circumstances the power went down. The battery screen shows only the last 52 minutes and does not include the screen on/WLAN/GPS/awake times. So it does not show which share the screen had in the power consumption during those 7 hours. If you had the screen on most of the time and used your phone - even for light things - 50% seems not too bad. If it was off most of the time, it probably took less than 53% power.
And in Better Battery Stats, you can select between "since unplugged" (that's what you have, showing only 8 useless minutes), "since charged" (that's what you want to check) and "since custom reference" (also very interesting, if you want to check the power usage during a certain time). Also check the kernel wakelocks.
turn down brightnis
Thanks for the replies, here is some more screen shots about Partial/Kernal wakeups
I noticed some wakeups in the kernal, i just changed my background to a black one also done some tweaks, ill report back tomorrow, meanwhile if those screens indicate for a problem, please share the solution
PS: Also i'll try CF-Root LP7 instead of siyah
In battery post your display time
Wakelocks are probably not your problem. The device was awake not much longer than the screen was on.
Also, did you notice that the power went up even after disconnecting from the charger? And before, there is sudden decrease, probably you restarted the phone at that time. You might want to try to reset the fuel-gauge chip with ExTweaks.

That what i thought too, not wake locks, because sometimes battery behave good but it drops fast after it wake up, also i've been monitoring the wake locks and everything seems fine, i've reseted my "Fuel-Gauge" My battery dropped to 12%, What is this chip suppose to do? Thanks

Here is my screen on time.. finally found it lol
Hey guys, I am having a problem with my Amaze, more specifically, the battery is dying absolutely WAY to quickly. For example, yesterday morning, after unplugging my fully charged phone, I dropped it straight into my pocket, and maybe looked at it twice the entire day. When I pull it it at the end of the day, the battery is red, with 8% left. If I were to be using it, the battery would last about 30 minutes on a full charge, most likely. I've also noticed that the phone is really hot, even in my pocket. If it helps, I am on ICS and have been using it since it was leaked in April, however, this problem is new (about 2 days ago is when it first started), as I usually get about 8-10 hours with moderate usage. Can you guys please help me? Thanks!
Well if it just started happening recently, and you haven't made any changes, then the battery may just be going bad... If that's the case, you can call HTC and they will send you one free replacement.

could be just the battery.. but if you don't mind me asking - how long have you owned the device? I suggest you dl JuiceDefender from the playstore and see if that helps - Definitely helps my device get through the day with moderate use and one time charge every 1 1/4 a day but this could vary on owners usage. Also, check your settings to conserve battery life such as turning off wifi, gps, auto syncs on your fb, gmail etc. and adjust your brightness to the lowest if possible and OH... less widgets and windows > less power that the battery consumes. Hope that helps!

Like I said, this just started happening. I didn't just decide to leave all my wifi and GPS and Bluetooth on all day. Also, to answer your question, I've had it since the beginning of the year. I think it's just the battery. I'll call HTC and report back.
cool.. i'm hoping its just the battery.

Nope, battery life isn't that great with this phone, depending on how much you use your phone and what all you use it for you will get any where from 6-14 hrs + or - some. Also your Rom and kernel will make a difference..

Nice!... Glad to hear
This happens to me from time to time, and the phone is ALWAYS hot when this happens.
What I've come to discover that it's usually something that' activating the phone while asleep.
The phone is hot, because the processor is being used. That's why the battery is completely dead so quickly, something is pulling it out of deep sleep and causing it to run full bore. The key sign is the phone is hot.
I recommend you get an app that lets you see wakelocks, and what's keeping the phone awake etc (I use GSAM battery monitor) Whenever I notice my phone becoming hot for no apparent reason, I know for a FACT that my battery will be dead in a matter of hours. Lately it has been "Android System" that's the culprit, and I can't quite nail down what is doing it, but it's very random and not much of a problem because I do a reboot and things are back to normal.
First, try to reboot your phone. Get system tuner and see what processes are using the processor when the phone is hot (make sure you show ALL processes, even the default excluded ones). Check the wakelocks. Get battery monitor and check the mA usage (it keeps a running history). When my phone is running optimally, I have a mA drain of around 70-90mA when screen off/deep sleep, and it should maintain this type of drain... when my phone is becoming hot for no reason, I see numbers anywhere from 300-600mA drain for no apparent reason. A lot of the time there was an APP that was offending, so I would first check that. Like I said though lately it has been "Android System" and it's kind of hard to nail that down, but it's so random.
When my phone is cool to the touch most of the time, I know it's running optimally because it's achieving deep sleep. I've found a lot of it has to do with what you had running before you turn the screen off. A reboot ALWAYS fixes it for me. If you can't seem to nail down the offending app, do a full reset back to stock and you should notice that your phone runs very very cool when the screen is off and it's sleeping. I usually get anywhere from 24hrs-2 days of moderate use with the screen off governor set to conservative, and maximum clock for screen off ~600mHZ. I use interactive governor for screen on, but that's for responsiveness and you'll probably have better luck with ondemand for battery life. YOu can set these in System Tuner.
Just remember, if the phone is HOT, it's using energy. If it's hot, something, somewhere, is causing the processor to run at a high clock frequency. If the phone is HOT after being in your pocket/screen off for a good amount of time, something is definitely wrong/rogue app. The phone should never be hot returning from deep sleep. I bet if you check your default battery monitor (The android one) you'll notice that the bar for AWAKE is probably almost solid blue, something is preventing it from going into deep sleep. If I notice my phone is hot when I take it out of my pocket, I immediately know that something isn't right. This should NOT happen.

I'm just past my 9th day of using my Amaze 4G.... so far, if I turn off data and turn off autosync, my drain per hour goes below 1%/hour... so i could get >50 hour idle battery life + 4 hours screen usage
with data on and autosync off, maybe 2%/hour -> this translates to ~ 20hour idle battery life + 4 hour screen usage
with data on and autosync on, maybe 4%/hour -> 10 hour idle battery + 4 hour screen usage

what program do you use to measure battery drain? I use Battery Monitor Widget, but it's not giving me an accurate answer (lets say I had the phone on idle w/o data/sync... the available % is stable over 5 hours (~1% loss per hour), but the current usage says at least -100mAh)
for me, the idle battery drain (apps autosyncing/using data) is the problem
I see my device properly going to sleep (deep sleep is the majority of the usage, not too many wakelocks/processes.....)
with data off and sync off, idle battery usage goes to a minimum

I use battery monitor widget to measure drain.. as far as accuracy, I'm not sure? I don't know if it's EXACT but it seems to be a pretty good indicator of drain. When in deep sleep the phone usually measures anywhere from 70~mA-120mA. Usually it stays below 100. Before I changed the screen off governor / max freq (screen off) it was almost always 100+. Screen off governor is conservative with a max freq of ~600MHz.
I have no idea how exact it is, but when it's reporting ~300mA, my battery is definitely draining much faster.. and when it's reporting 500-900mA~ my battery is draining incredibly fast, so it at least seems to be a solid indicator of current usage.

On my previous phone (LG Optimus T / Optimus One/ P509, CM9 ICS ROM), Battery Monitor Widget reports more accurate readings (idle with data off= -2mA or -20mA<dont remember>, accurately representing that 1% of battery would last at least 2 hours)
Phone with the new kernel (KozmiK Ruby -0.5a) still goes battery drain crazy (even with Juice Defender installed now).... I hit 10%, then got fed up, turned off data... then the phone slowly sipped battery for the next 3 hours going down only 1%.... sigh
I think Facebook Messenger is the data hogger in my case, since I do use it often... will try a new ROM build without logging onto facebook messenger, see how it goes

What you said is true, at least for data on - autosync on. My battery last around 10 hours idle + 3.5 - 4 hours on screen usage. It seems that autosync eats a lot of battery. Will try to turn that monster off and see how much it will improve. I have bad habit to push refresh button on gmail/facebook widget, even with autosync on,
I used to get 14-16 hours. Now my battery won't last more than 6 hours. I gotta replace my Anker

Most recently I got 1 day and five hours with a fair amount of use by using faux 011 kernel and using CPU editor script to set it to battery saving profile. I'm at 45% right now with fairly heavy use after over 18 hours.
Battery life is totally under your control, it takes some work to get it where you want it.. but you also have the option of buying a bigger anker battery with external charger for $20 and carrying that spare battery, and simply not giving a damn.
Just saying, battery doesn't have to matter for a very small price and a little space to carry the spare battery in your pocket.

I'm having this issue of my phone not sleeping when the phone is off. I checked kernel wakelocks and the number 1 culprit is Power Manager Service. Anybody have any idea what this is. A distant second is wlan_rx_wake but I'm not too worried about this.
The devs are working on it. If you aren't on the latest CM9 build then you should update.

I'm actually not on AOSP stuff. I'm on one of Neo's roms.
Edit: I just ran a test and for 34 minutes the phone slept for 33 of them. Even though the phone lost 4 percent of battery in that time. I see people saying they have crazy good battery drain rates (like .25%/hr). I thought i would get better life but I guess thats just the way it is.

that rate is based on usage. keeping apps from starting. keeping apps running in foreground all the time. lots of frozen unnecessary apps. screen brightness between 10-20%. betterbatterystats monitors wakelocks

When saying .25% per hour I was talking about during sleep but I get 3-4% during sleep. I am going to try and wipe everything and start from scratch. But if my phone is sleeping >90% of the time when the screen is off, there's not much I can do to improve battery drain during sleep no(app wise), and screen brightness won't help at this level cause it's when the screen is off?
have to watch for partial wakelocks or any wakelocks. apps automatically starting when not needed or still running will reduce your amount of deep sleep. use betterbatterystats to monitor usage while it's off
Hi guys, I have a problem with cm10 based rom (PA2.53), cpu doesn't go into deep sleep when it is supposed to. It does go in deep sleep, but for very short lenghts of time, during the night (with quiet time enabled and jd plus) i lost more than 10%/hr (from 100 to 20 in little more than 6 hours idle), I checked cpu spy and of 6 hours idle little more than 1 was in deep sleep and 5 at minimun clock freq (134), there's no app keeping the phone up as battery was drained for 70% by android os (which also shows cpu awake for more than 5hrs).
Any suggestion to fix this? I know battery drain is "supposed" to be high on jb, but isn't over 10%/hr in idle a little too much?
Using mesa 2.3, smartassV2, min 134 max 1200, jd plus, startup manager and fast dormany tweaks in init.d...any suggestions to fix this problem?

I tried a last resort solution and it seems to be working (not too stable but better than before) I completely discharged the phone, recharged it fully while shut down and battery consumption seems to have improved. I lost 6% right away when unplugged it from charger within 30minutes, but now i have 12.30h running on battery and it's down to 84%, so aside form the 6% that drained immediately from 100 to 94 the rest seems to be keeping up pretty well. I'll keep an eye on it though as it seems to vary from time to time...In two days new pa and new fxp should be out, I'll see if that makes anything better...
Thanks for reading and for the replies so far
I think i found out what is causing the high battery drainage, it's the mobile data connection. For some reason JD (or the system) can't shut it down when phone is at sleep. Last night i switched mobile data off and in the morning i had almost less than 0.5% drainage, as soon as i turned it back on battery percentage started dropping at sight...
Battery Calibration
Download BatteryCallibration app from the market and follow the steps given there..
Helps me everytime i have a battery issue...
HIT THANKS IF THIS HELPED
Thanks for suggestion but that doesn't help, i used zepps die hard calibrator before, but it's not a battery problem. Random processes at random times will keep the cpu running when it's supposed to sleep, that's what's draining the battery..
Perhaps an app is polling the net too often, facebook anyone?
Xperia mini (smultron), CM10 150, Xtended kernel + rom
No i have app control which prevents any unwanted things to start-up automatically (and fb is on the no-fly list )
I think i kinda sorted it out, what causes the problem is thethering. When i disconnect tethering according to phone wifi and data are off, but in truth they keep staying on. I shut tether off and can still see my hotspot from pc even if wifi is completely off on the phone! So it's wifi and data which keep staying awake (even with screen of for long periods of time) and slowly drains the juices.
Well i just got the LG G3 and am using it on GSM.
prior to using i rooted ,TWRP and loaded jasmine 4.0 , also put in skydragon kernel 2.9.4 s 3.0 had crazy boot times.
I am trying to get the max out of the phone what ive noticed is that the phone just doesn't wanna deep sleep.
I have greenify , xposed (amplify) and noticed the issue of battery being drained when idle , i went to sleep and saw it was at 50% , woke up to 10% battery, my older phones never dropped more than 2% overnight,
To investigate loaded BBS and wakelock detector , nothing that pops up out of the ordinary
So my question is what do you guys do to max the battery outta this , what can i do ? i dont really see any apps causing it to wakeup . suggestions or any would be appreciated
any other stock rom also if you could suggest for battery life ? ive heard good about cloudy 1.2 as well.
I have really gotten great battery life out of sky dragon along with the 3.0.2 SD kernel (kernel is in the orig Dev section). Along with amplify ad greenify.

Are you connected to WiFi when your phone won't deep sleep?
I work from home, so my phone spends 90% of its time on WiFi - I was getting terrible battery drain and only 50% deep sleep on a good day. One day, I left the house and noticed great battery life and plenty of deep sleep on a 4G connection (which is the opposite of what I expected).
After trying nearly everything, I discovered the fix was as a simple as turning on the "Battery Saving for WiFi" setting under Settings -> Wi-Fi -> Advanced Wi-Fi". I've been getting great battery life and deep sleep times when I'm at home now.
Give it a shot and see if it solves your issue.
Also, ever since daylight savings time went into effect, I noticed both my phone and my wife's phone keep randomly changing time zone for no reason. Looks like the phone is struggling to automatically detect the time zone from the carrier and causing battery drain as a result. I disabled the setting to automatically detect the time zone (and manually set it for PDT) and the battery drain stopped on both of our devices. Could be unique to my area but may be something to try as well.

Give it a shot and see if it solves your issue.
Also, ever since daylight savings time went into effect, I noticed both my phone and my wife's phone keep randomly changing time zone for no reason. Looks like the phone is struggling to automatically detect the time zone from the carrier and causing battery drain as a result. I disabled the setting to automatically detect the time zone (and manually set it for PDT) and the battery drain stopped on both of our devices. Could be unique to my area but may be something to try as well.

I thought the same as well which is why I discounted this as being a cause for 4 months....I have 15 other android devices and none have exhibited this behavior so I was surprised that such a trivial setting could have had this impact.
To answer your question, I am currently running:
- BeanTowns stock 11B ROM
- SkyDragon 2.9.7 kernel
- Xposed installed with Disabled Services running
- Selected stock apps/services disabled
I don't use greenify/amplify (don't see the need as my average daily drop is anywhere from 1.6% - 2.4%/hour with moderate use).
