I have had my tablet off the charger now for 1 day 14 hours and I have 61% battery left. I have used it periodically to read the paper and check email over the course of the least two days.
My settings include auto brightness, screen sleep after 10 minutes and wifi always on. I let the tab go to sleep on its own.. I do not force it with the power button. I revive it with the volume control.
I am running for months now tnt 4.1.0
I am not sure why there are complaints about a true "standby" or sleep state as I can not expect any better always on battery life than this.

There are two levels of sleep. Screen off but CPU on and wifi on will run about 3% per hour. If you run the stock rom and let it go into deep sleep it will halt the CPU and shut down wifi after 2 minuets or so, and in that state it should burn about 1% per hour. It wont do alarms or reminders or check emails when in deep sleep.
So you can go about 33 hours without deep sleep. Or pretty much one day of use with alarms/alerts/push email. Or 3 days and off and on use with deep sleep. I prefer the one without deep sleep. I just charge it every night. I agree though, in with case it seems fine to me.
There are so many threads on this issue... it'd be good for the mods to combine them or lock/link to one master? Much like the 96% issue... both need dev attention and less General threads!
I have raised a bug with CM7 on the idle power problem. Idle power usage is huge compared to other devices. Hopefully this can be fixed...

"Currentwidget shows >300ma power usage at idle" from your report... do you happen to have the OC pegged high in SetCPU? Because wifi on, bt off, idle/screen on should be in the low 200s (214mhz clock scale) and wifi on, bt off, idle/screen off should come in at 100-120.
This isn't a "dev" issue - it's a hardware design issue. The gtab isn't designed for long standby, no amount of dev attention will fix that. 100ma seems to be the floor (with wifi on.)

I agree, I can go about 30 hours before I have to charge it again. I do let it sleep but keep the wifi active as it has issues otherwise. It is a hardware limitation on the device not a dev issue.

This was with wifi on, bt off, screen on auto brightness, cpu pegged to 214mhz with screen off, pershoot kernel.
I disagree that it's not a developer issue. Based on my experience with Android on the HD2, a lot of the battery usage issues eventually came down to kernel optimisation -- incorrect GPIOs causing devices/sensors to remain on when the kernel thought they were off, high bt idle drain, incorrect voltages against cpu speeds in the scaling tables, backlight driver loops, etc. I do not think this is related to the device itself.
I can get ~48 hours standby, but this thing should be measuring standby in weeks, not days. My HD2 can get >2 days standby, probably 4 or 5 in airplane mode. It draws 3ma!
Cheers,
Jason

Right - that would be a firmware deep sleep, where the firmware halts the cpu, and powers down hardware.
Note that when cpu halt ends the control of the OS right there.
The gtab's "deep sleep" isn't a whole lot better than "screen off, cpu lowest speed." No amount of kernel work is going to fix that.
Running VEGAN Ginger Edition, I get a full 8 hour work days use at the cost of about 20% battery life, probably about 6 hours of that is idling, the other two are browsing the web / goofing off playing Meteors or something.
Is deep sleep a stock state for our phones(all Android phones?) or is it a product of the custom kernels?
Ever since I installed Doomkernel v3c and created a screen off powersave profile with setcpu I'm getting stupid good battery life. A full day of moderate useage and I'm still in the 75-80% batt life and obviously a big part of that is all the time spent in deep sleep when the screen is off.

some1 knows how Deep sleep works ? From the technical side...
the SoC totaly deactivates CPU part, and phone works on another small processor ? or still works but only clocks with 19 mhz ?
as much as i know i think the Deep sleep things totally deactivates CPU and whatever work being down will be paused and transfer to Hard drive/non volatile storage.. the only thing active at that moment is RAM. and in Deep sleep even u have noticed that it takes a fraction of second extra as compared to normal mode .... coz the processor cache is fully flushed at the time jus before Deep Sleep...
Jus answer based on xperience of what i think ..might be rite or wrong too !!
Im getting battery drainage problem on my X10 in sleep mode it drains from 100% to 75% just in seven hours im running WB 4.04S. Please help me i ve tried all of calibration methods but all of them suck.
Install CPU Spy, Reset Timer, Let phone go to Sleep mode! Look again after 5-7h. I'm sure you're phone isn't the entrie Time in Deep sleep, its only Screen off.
Maybe...
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.

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.

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.

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.
I just got my Alpha SM-G850F last week and I went straight to flashing 5.0.2 on it. After a couple wipes and reset to defaults it's now working fine but I'm still not happy with the battery life, especially while the device is idle.
My idle drain is about 3% per hour, which to me it seems a lot coming from a Z3c which usually has around 1% per hour in the same conditions (on WiFi at work or home).
Deep sleep seems to be active most of the time (according to CPU Spy), no rogue apps seem to be active (I even removed the official FB app for this tests) and I don't know what to look for anymore.
Here are the stats:
https://goo.gl/photos/fC5BbXqfZ8PpZFmy7
Some info on my setup:
- no power saving
- brightens on auto set to minimal
- location ON with high accuracy
- Bluetooth ON paired with G Watch R (switching it off at night does not make much difference)
- WiFi ON and connected
- Google Now OFF
- Nova Launcher instead of TouchWiz
- S Voice, S Health and the rest of S Krap disabled
I was wondering what's the average idle drain on WiFi for you guys.
PS: Is it normal that CPU Spy does not report above 1300Mhz (was it not supposed to go up to 1800) ?
First of all, Sony Xperia Z3 Compact has a bigger battery, 2600 mAh compared to Alpha's 1860 mAh battery. Second thing G850F has 2 processors, one clocked @ 1.3 GHz, second one clocked @ 1.8 GHz. I recommend turning all these settings off when you can (e.g. WiFi, bluetooth, location)
I've got a question though; does your touch screen work at the top left corner of the screen, like you can try swiping the navigation bar slowly from the top left corner and tell me if it goes back to its place (when im playing games buttons sometimes dont function)..
Best regards,

Of course there is a battery difference but still there is a big difference. Assuming the Alpha was half size that would still mean at most 2% drain. That's why I was asking for people to share their idle usage so I can compare. At the moment I'm flashing KK and I will report back after the weekend. I'm not about to dumb it down by turning off all the smart features that I use. I also remember I had the same high drain in the first version of lollipop for the z3c, but they fixed it in the meantime.
Regarding your touch screen issue, I saw your thread but I'm not experiencing it. I have no games to try with but in other apps I do not sense this issue.
Perhaps it's related to CPU usage which I assume it's pretty high during gaming ?
Battery is better in KK, idle drain dropped to less than 1.5% per hour, also memory management is way better and most of my apps are always in ram so they resume instantly, tho the system overall does not feel as snappy as with LP.
I miss the lock screen notifications and smart lock but I'm gonna stick with KK until a new version of LP turns out (hopefully 5.1.1).
Here are the stats:

I dont understand your statistics,but obviously Android system & kernel drain your buttery and this is not normally
but we have only first build of 502 jet,and I think newer version of 502 will be much better
Actually that's normal when you don't have any apps wreaking havoc in background when the screen is off. So basically what you're left with are the notifications, communication (WiFi, Bluetooth & GSM), location and the rest of the google/samsung stuff that you can't really control. Overall 26h with 1.5h SoT for such a small battery is reasonable to get you through the day.
Here is my idle drain after full charge and leaving the phone untouched through the night.

Power saving is off and I`m on Ozcan ROM. With my pattern of usage battery lasts for 2/2,5 day with around 2,5h SOT (no power saving and brightnes on auto 5).

Looks good. My battery went down about 14% over night from fully charged (as much as 20% on other 5.0.2 roms). Do you have exchange accounts? I've found them a bit of a drain in the past. I'll try again tonight and post some stats.
I have facebook, messenger, snapchat and 4 gmail accounts that have push notifications. I also use greenify with experimental functions enabled - it indeed saves some battery power.
