Question about the governor/cpu frequency scaling - HTC Amaze 4G

I've just done some undervolting and governor changes on my phone... (faux 012 kernel), build.prop added ro.ril.disable.power.collapse=0, pm.sleep_mode=1
On Powersave (where the CPU frequency is locked at the lowest 192mhz, I was able to hit 9mAh(reported by Battery Monitor Widget with HTC Sensation current detection option enabled) on idle with data on, sync on
Reported by the phone's built in stats:
30 min screen-on time, 1 hour phone on time, >12 hours deep sleep, my battery was just above 50%
of course, with frequency at 192mhz, there was major noticeable lag... one time, there was too much stuff running on the phone when it rang, and it couldn't work fast enough for me to answer the phone in time before bouncing to voicemail
lowest noted current usage before change - after change
deep sleep: 20mA | 9mA
screen on idle: 100mA | 60mA
9 hours usage before hitting 50% | >12 hours usage before hitting 50%
I've looked/used at the other available governors....
the interactive is next "power saving" efficient... clocks up from 192mhz somewhat slowly after some use, and goes back to 192mhz
the conservative is next... clocks up very fast from 192mhz use, slowly goes back to 192mhz
the ondemand clocks up faster and goes down slower
all of them clock up from 192mhz when the usage barely passes 50%
anyways... is there a way to customize my own needs? I want the phone on 192mhz until the CPU goes over 90% for 1s, then clocks up slowly... when a phone call comes in, i want it to use as much as it needs... etc

Maybe it's just me, but this phone is pretty fast/stable without missing with out volting

I just want to be able to maximize battery life when I need(eg when I'm going out and I know I won't be near a phone charger for more than 20 hours, and still need the use of GPS/camera etc)

There are several other things you can do which may be more effective than what you are trying to do- or even more effective WITH what you are trying to do.
First, don't lower the minimum clock speed, 384 is the minimum that HTC chose, probably for multiple reasons. As long as your phone is going into deep sleep, it doesn't use ANY processor, and on any governor EXCEPT battery saver, it is VERY rarely idling at the minimum speed.
Next, look at the init.post_boot.sh and init.qcom.post_boot.sh files(you may have one, or you may have both, faux added the second one in later builds) in the system/etc folder, that sets many of the kernel settings. Do some research into how changing the line for "down_differential"(which is 5 stock, 1 increases battery A LOT, but increases lag a bit too), , "up_threshold"(stock is 90, setting to 95 increases battery, but takes longer to get to full clock speed), "sampling_down_factor"(stock is 4, you can lower to 1 for increased battery life, and slightly more lag), "sampling_rate"(latest faux changes to 30000, setting to 50000 means it checks whether to increase/decrease cpu speed less often, and gives better battery life).. changing those values will have much bigger impact on battery life, while adding a little bit of lag at most if you change them quite a bit. Also, look to see if you have a line that says "echo 1 > /sys/devices/system/cpu/cpu1/online", if you do, change it to a 0, 1 forces the second core on ALL the time instead of letting ICS decide when to turn it on.
Next, look at thermald.conf in the same folder, some of the biggest differences in battery life between roms is because of that file- faux replaces it with his later kernels, but I'm not sure if it is to increase battery life, or increase performance. His is definitely different than any rom I have seen, and people report much improved battery, and that file is likely why.
Doing all of these things with system files rather than with a 3rd party CPU app means the phone will deep sleep more, and be more responsive, because there is no app constantly running in the background trying to make changes on the fly. Also, you can find "battery saver" scripts that can be put into the above files that have their own tweaks you can make if you are determined to use that governor- but battery saver tries to constantly stay at the minimum speed possible(if you read it in some places, it simply stays at minimum speed PERIOD), and will have the most extreme lag, with a questionable amount of increased battery life compared to a tweaked on_demand governor.
And last, before undervolting, try decreasing the max speed of the core.. you can lower it by 1-2 steps and notice NO difference in speeds, yet get far better gains than undervolting, without creating instability. The volts that HTC chose are probably the very minimum that works well for all of our phones, as undervolting by 12.5 may work fine on my phone, but may introduce random reboots or worse on yours- once you undervolt you simply can't troubleshoot any issue on your phone, because the UV could be the cause instead of anything else..
There is more than that you can do also, like making sure that your screen-on and your actual usage numbers are almost EXACTLY the same- get an app like betterbatterystats(available free on XDA) to see what partial-wakelocks are keeping your phone from deep-sleep.. the higher the % of deep sleep, the less you have to worry about ANYTHING to do with the CPU, since the CPU isn't being used at all..

If you do everything I said above to maximize battery on the on_demand governor, you can use a CPU app to change to battery saver governor when you know you won't be near a charger, and you just want basic functionality(no games, browser, etc), and DONT set on boot.. that way on reboot it defaults to normal governor.
I tweaked all the things I said above and get at LEAST 16+ hours with 3+ hours of screen on, and will get over 24 hours if I underclock to around 1.2ghz.. battery saver isn't even needed if you set everything else right.
Or you can buy 2 1900mah ankers and an external charger for 29.99 and free shipping on amazon, and simply carry the spare charged battery, and never care again.. much simpler fix if you ask me.

thanks for the tips Silentbtdeadly. I'll look at them this weekend
I am already using the Anker 1900mAh battery, with the latest faux kernel and energy stock ICS rom...
I get maybe 15 hours from 100% to 10% with ~1-2 hours of usage
From looking at BetterBatteryStats, it looks like the phone is falling into deep sleep properly with no obvious problems with wakelocks/alarms...
If I left my phone unplugged overnight with data on and autosync, it levels out.... lost 9% over 6 hours
I think I just have 2 main problems:
Drain from 100%->80% is fast after unplug... I think it takes 30 minutes to get to 90% and another 60 minutes to get to 80%. BBS shows phone in deep sleep, Battery Monitor Widget shows mA usage ~50mAh with -2%/hour, but the %-left slopes down a lot, since i did lose 20% in 90 minutes
when I turn on the phone and use it for <1 minute and put it back to sleep... Battery Monitor Widget shows a sharp drop in %-left even though BBS shows falling into deep sleep
I guess my problem might be the battery-monitoring hardware/firmware... I just received the Digital Timer, will try Bump Charging to see if I can get 16-20 hours with 3 hours of usage

Careful with battery monitor widget, the way it polls the battery creates its own drain.. there is another widget called currentwidget that can actually log how much energy is being used by an app, it too can drain a lot, but it could show you if a certain app is using an absurd amount of power.. I have more info for it in the battery saver section of the bible in my signature.
I think about 16 hours with 2-4 hours of screen on is the most that can be gotten without seriously degrading the performance. If you set the governor options like I said in the last post and under clock a little, you will get a little lag on minor things, but the phone is still quite usable, and 24 hours is totally doable at those settings with 3-4 hours screen on.
Do realize the anker batteries aren't perfect, I bought two at once.. one gives me much more battery life than the other does even tho they were bought together, so that could be a factor too. I try to maximize battery life, but I'll carry a spare charged battery so I don't worry too much, it is the best solution thus far.

with setVSel I was able to extend the battery time to almost 60 hours !
with juice defender I got less battery time than without it (around 48 hours without and not more than 46 hours with juice defender)
So my choice is clear !

What are your settings and what is your usage?
Setvsel installed i noticed little hangs between clock speed changes.
I've made stability tests but testing at 300mhz sometimes the clock speed icon goes to orange (full speed) during the test even at default voltage.

How can you people do 60hrs, with my moto defy, set vsel on 1. 18-300 2. 25-500 3. 40-800, i can do near 30hrs with single charge. I am online on GTalk all the time, and that is all, 10mins call, 30min browser and 1hr Gtalk chat.

Yes I notice the same and prefer performance mode to default on demand mode. Unfortunately performance mode is not remembered at the moment and has to be set every time after restart.

There is a lot of factors, too many to list. But, I'd say the biggest is the rom. I have two defy's, the wife's is running stock tmous 2.2 and mine is running Pays v4 which is blurless. Both are overclocked using setvsel at 30/300, 54/700, 70/1200 with 86% threshold.
I just got 55 hours with heavy use (wifi, mp3, games, talking/text, gps, etc)...had 34% remaining 48 hours in last I checked, but a few hours later killed it off with the mp3 player while running (and using a gps running app) the last couple hours. The wife's phone gets a a little more use from ereading and she is averaging in between 32-36 hours, which is about the same that I was getting before Pays rom.
In short, the more apps and services running in the background even when not in use...the more consumption. But like I said, there are a lot more factors at play.

True. Having SetVsel + Uninstalling useless or unneeded system services give me 2 days of battery under normal use, and turning off the wirelesss is making now a big difference, 2 days and 4 hours runnning on the same charge at still 55%. (i have to remark i am having almost no use of the phone this 2 days)
I have juice defender and setvsel together they work great i have no problems and my battery doesnt drains fast

Juicedefender is a really beutifull program. The problem is that it spends as many juice as it saves. Its pointless having it. I have 3 days of battery since i manually turn off-on wifi.

I have no evidence, but I kinda think the same...running another app to kill another app might be like robbing Peter to pay Paul. Since my last post, I've decided to go more minimal, got rid of task killer and setvsel and only using milestone (milestone is probably not needed either but can't go completely naked just yet)
The phone is still zippy and I notice it doesn't overheat as much. As for battery consumption, I haven't given it enough time to compare. But given that I'm not overheating as much is a big plus.
i have 3-4 days of battery under light-moderate use. i ussually dont have a chance to deplete it completely because i move pictures between laptop phone, or use adb to do stuff , so it always get some charge from USB.
Omg reading older posts i noticed some people don't realize the advantage of setvsel over everything else including milestone overclock.
First it can work as an overclocker like milestone OC but more important as an undervolter.
Stock values are 33 - 300 Mhz 48 - 600 mhz and 58 - 800 mhz
I go with 18-300mhz 30-600mhz 40-800mhz less volts longer battery life.
And imagine feed the cpu with less volts and at the same time overclock it for faster speed. Yeah. some people do that,
18-300 40-800 55-1000. At max speed you feed same power and get extra 200mhz.
If you use a task killer once, ok, but if the task killer is automatic and kill for you at intervals it worsen performance because android likes to ressurrect apps, it kills 12 apps, and in 60 sec bang, android revive them, so you enter an endless cicle of kill - resurrect.
And juice defender its a heavy app. eats too much cicles.
Oh and Turning Wifi OFF, or "Always ON". increased 20% battery life.

And about task killers, if its a one time use its ok, but if the task killer is automatic and kill automatically at time intervals it worsen performance because android likes to ressurrect apps, it kills 12 apps, and in 60 sec bang, android revive them, so you enter an endless cicle of kill - resurrect.
And juice defender its a heavy app. i see 5% total consumption in battery stats and i think that's a bit high for a program who claims to save battery.
Oh and Turning Wifi completely OFF and/or setting "wifi sleep policy never" . increased 15%-20% battery life. (wierd might seem but wifi sleep policy when screen is off is worse for battery)

Screen Off profile, revisited

I haven't used a CPU control, overclocking/underclocking app since I had the Incredible. Like many, I haven't been too thrilled with the Rez's battery life. A few days ago I decided to grab SetCPU off the forums and see if I could improve things.
I set a screen off profile to 384/192/interactive, and also spent much of the day with the screen on speed underclocked to 810/192 (by default, the minimum speed is set to 384 and 192 isn't used...). Even at 810 MHz the phone is plenty speedy enough for "normal" activities, I.e.: text, email, short browsing sessions. When I needed it I bumped speed back up to 1510.
End result? 14 hours off charger, 47% life left (screenshot attached). With a decent amount of usage, browsing, texting, email, and shooting a 10 minute 720p video. Typically, the phone will lose 5-10% per hour unless I'm not using it at all. With pretty regularly use throughout the day (note the screen on blips) with these new profiles, I was losing about 3.5% per hour. Well worth a barely-perceptible drop in performance, IMO.
this is on the last official OTA, with a TON of apps/bloat removed, and on the stock kernel.
Bud, I am on CleanROM 3.7, use 4G all day long, tons of screen on time, no CPU or voltage changes and I can make it damn near 24 hours off the charger, lol.

+1.
HTC phones generally do not get good battery life, but I haven't had the terrible life that a lot of people on the forums do. It's on par with the Incredible, I'd say. Not great, but it could be much worse.
then you are one of the Lucky ones or have an extended battery. I see a lottttttt of guys who can barely make it 12 hours on a charge.
I envy you or anyone that can underclock under 1188 without freezing.
sent from my ICS flavored HTC Vigorous Vigor. If I helped please use the "thanks" option!
I have various profiles that set the CPU at different speeds depending on screen state or battery life.
It goes from 384/1728/interactive when its at 100% and gradually scales down to 192/540/conservative when its <8%.
When the screen is off, I have it set to 192/702/interactive, unless the battery is less than 25% at which time that profile (192/648/conservative) becomes active even when the screen is off.
When on a phone call, the CPU speed is set to 384/1022/interactive, even when the screen is off, unless the battery is less than 25%.
My phone actually behaves pretty reasonable at 192/540/conservative. It must not lower the GPU speeds, as the graphics appear to draw just as fast when underclocked as it does when overclocked. Where I do notice a difference is when I'm tethering - lower CPU speeds usually results in noticeably lower throughput to tethered devices.
LOL, I can't imagine doing all this BS to get a little better battery life.
I leave everything on, full speed, 4G all day & carry a spare battery -problem solved.
Hell, these batteries are so small & light you could carry four extras & not even know they where in your pocket.

Agreed. Mine only drops 1 or 2% overnight if I forget to plug it in. As long as the screen is off, the Rezound practically lasts a week. Its the damn screen that actually kills it so fast!
Can't fathom why if you are sleeping and not using the phone, not putting the phone on the charger??
Putting it in airplane mode defeats the primary purpose of it being a phone as well.
I really don't use my phone as a daily wakeup alarm except for unusual wake up times from time to time, but not having the phone fully charged in the morning seems kind of pointless when you have an easy charge time avail when you are not sleeping.
My phone lasts typically 12 to 14 hours with everything turned on except BT if I'm not using it.

Someone who doesn't need to use their phone all day should do a test with exactly the same cpu on both phones, except one has just a screen off profile so we can rule out almost all variables and see if screen off actually does help

Battery Drain EXTREMEMLY Fast

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!

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

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.

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.

Share your battery life & temperature please

Hey, so I've seen several people claiming fantastic battery life, etc. So, I am just wondering what's your experience in general. If you've got some free time and feel like typing, can you list several things like:
roms & kernel
stock/anker battery
battery life
screen time (and possibly voice call time or whatever else that seems to consume lots of the battery life)
highest battery temperature (I recently got pretty high so I was kind of worried)
and anything else you think might worth sharing (favorite actress? :silly
As for me, I recently installed Speed ROM 6.5 with stock kernel on stock battery
I only got 8 hours battery life to get to 14% with 3 hours of screen time (mostly used for game, browsing, and flipboard)
I got up to 100F (~40.5C) after playing a game for about 15-20 mins which made me leave it for a few mins to cool down. The next time I played the game again, it got up to 109F (~43.5C) after playing for 20-30 mins....
I am wondering whether that kind of high temperature is normal or not, and whether my battery life seems ok or bad; which is why I am hoping people can share their experience here. I haven't try using faux kernel though (might try it tomorrow in hope for a better batter life)....
So, again... if anyone got free time and feel like typing, please share it with me :angel:
From my g2 to this phone all I ever see is how bad the battery is. Never noticed a difference switching roms and battery across all smartphones I've used is allot what I expect.
Some people just can't be happy you know. Not to mention people never agree on anything (me included ).
Just my two cents

Well, first off, I am not trying to complain about the phone here. All I am asking/trying to find out is whether my experience is "normal" or not for Amaze.
I also come from G2 and obviously the battery life will be worse on the Amaze in general. This phone is 1.5ghz dual core and 4.3" display compared to 800mhz single core and 3.7" display on g2 with only extra ~300mah on the amaze.
I just want to know if my experience of getting only 8 hours battery life (with 3 hours of screen time consist of game and browsing) and getting a high temperature of 109F on the battery is considered "normal" or not for this particular phone. I only have one phone here; so, I don't know if my unit is bad unit or if it is normal for the Amaze.
So again, by all means, I am not trying to complain about this amazing phone here. I am just trying to find out if this is what normally happen with this phone.
And yeah I'm one of those guys that can never be happy :silly:. When I used G2, I want larger phone and faster performance. When I got Amaze, I want slightly larger screen and much better battery performance. So, yeah I can never be happy with my phone :laugh:
The temperature thing is definately normal, it can get pretty high. I've had it go above 109f while on video chats on Skype. As for thebattery, that's normal too its just dependent on the user. U may have something that's running continuously in the background that your not aware of that's causing drainage. Many things that could be effecting the battery really

@OP, most likely you either have a bad battery, or your phone isn't sleeping properly on idle, or your phone has some problems with the RUU
Code:
Battery is ~1900mAh. If you use it for 3 hours active at around 400mAh, that is 1200mAh
700mAh left for idling the rest of the 5 hours. My idle current usage is around 9-40mAh as reported by Battery Monitor Widget(go to settings, change monitoring mAh to HTC Sensation to get a better reading)
700/5 = 120mAh/hour.... this means your phone isn't sleeping properly
Get CPU Spy... install it, then put your phone down for an hour without using it.... after that, does the report show that it goes to deep sleep?
When I got my phone and flashed the ENERGY rom, I had ~8 hours of total uptime (1-2 hours of usage)... i reflashed the RUU (do it on 100% battery), then it is better now
Now, on the Energy STOCK ICS rom with FAUX latest(0.12?)
Anker battery
15 hours of uptime
1-2 hours of screen-on time(roughly 2-3 hours of phone "awake" time)
don't remember battery temps, but i don't ever remember ti being that high
interactive governor, max frequency 1.4 ghz(to maximize battery life)
data on, autosync on, 2 gmail accounts synced only
My 100%->80% battery drains in 90 minutes, but after that, it slows down
I added the following to build.prop to tweak more battery life
Code:
# Power Save Tweaks
ro.ril.disable.power.collapse=0
pm.sleep_mode=1
If you really want to stretch out the battery, change the governor to powersave(forces processor to 192mhz always), but it definitely lags and I wouldn't recommend it unless you really really need to max battery life
EDIT: Go to Settings->power->see what is using my battery, post a screenshot (this one is 16 hours plus ~2 hours usage)
see the part that says "awake", and the part that says "screen on"? It should be correlate mostly -> when you use your phone's screen, the phone is awake.... when you turn off the screen, the device should be sleeping and not be awake

I guess this phone is just that "hot" eh....
So, you're saying that I should be able to get a better battery life than that?
By the way, did you use Juice Defender or anything like that? Or did you just let your mobile network and wifi on all the time?

Hmm... I would try to check the stuff that you said. I did see the battery use like you did and I have much more awake (since I used it for games and browsing continuosly). But, when I was not using it, it doesn't show that many "awake" status which is why I thought that Amaze battery performance is just that poor. I forgot to try third party app like battery current widget or cpu spy. I will check those out.
Did you use Juice defender or anything like that? Or, did you just set them manually when you need it?
And I did leave my WiFi and auto sync on.... From your usage, I'd assume you turn off your WiFi when you're not using it, right?
Thanks for the input
Edit: So, I am guessing there's a rogue app on my phone? I just reboot my phone, leave it for a minute, and battery current widget shows 200mA on my notification bar
From what I'm reading your a heavy user. Like me lol. The most I get is 6-8 hrs. With 1.5-2 hrs screen on time. Comparing that with others who get double digits It's nothing but I'm a heavy user. I stream Pandora daily surf the internet for 1 hr non stop, xda for most of the time. . And on weekends I'll have most 4 hrs. But 3.5 of those screen on with data streaming and screen on with out going off. Kinda like watching a netflix movie on mobile network. I use my phone like if it is my laptop now. I rarely use my laptop. I don't have internet nor WiFi to connect to. But if I tether I would run out of data faster so I avoid it. Besides battery draining faster.
I think there is a difference between:
1. leaving the screen on for a while, causing the phone and battery to get hot. Specially when gaming because CPU is constantly running.
2. And total screen on time accumulated of 2-4 hrs screen on. Which is achieved when sporadically checking phone for text, calls, email, quick surfing. Then shutting of screen through out the day.CPU goes to deep sleep phone stays cool.
Now that's what I call a heavy user.
Remember when phone is hot battery drains faster so you need to find a way to cool it down. Sometimes there are settings in cpu apps that when phone reaches certain temperature that app will force cpu clock down a lot as to use less power to start cooling down but causing lag.
I've got a 4 month old stock battery with latest faux kernel v.16 with battery saving tweaks on it. Energy rom stock 8-1. If there is anybody that reaches double digits with 6-7 hours 4g mobile streaming not wifi at all. 2 hrs without turning the screen off not 2 total hours. Please say I? I'd really like to know your secret.

Battery Current Widget... go to the options (top right), change the current selection(should be first row, then middle row) to "HTC Sensation" (it'll be more accurate)
that program doesn't accurately report mA if you don't change it(before changing, it'll be screen-off deep sleep 100mAh, but after switching, 10-40mAh)
I don't have Juice Defender on... autosync and data is on all the time
try w/o wifi on... i think wifi should take less battery power than data, but it always depends
on my screenshot, if you go back one and click on the screen-on... what does it say?
what does CPU Spy say about your phone going to deep sleep?

if you are only getting 8 hours uptime with 1-2 hours of usage, then your phone's not going to sleep properly... I'd reflash the RUU, then flash Energy ROM and faux kernel... i had that problem before I reflashed RUU (but that was before I knew more about CPU states and mAh usage on this phone, so I don't know if it was a problem with the deep sleep, or the phone not properly updated to ICS when I got it from someone else)
you want to try to max battery life? I can give you hints to hit that mark... it's all about physics/electronics
your battery is 1900mAh.... Using Battery Monitor Widget(with the Settings changed to detect the phone as "HTC Sensation", see above)
With the tweaks in my first post of the build.prop, BMW shows my idle around 10-40mAh..... 10 hours of idle = 100-400mAh. Note, this is with sync and data on... if you use Juice Defender or data off, probably less
So, idle, you use up 400mAh... you have 1500mAh left
1500mAh / 6 hours = 250mAh each hour.... with BWM, it shows that the current usage goes between 100-500mAh depending on how much screen brightness, data used, processor speed... If i choose powersave, I think it goes between 50-300mAh, but its really laggy, noticeable
300mAh * 6 hours = 1800... close enough
to avoid the 100%->90% fast drain, employ bump charging:
either
1) charge your phone to 100%. remove plug, wait for it to drop to 90%. replug it, charge to 100%... repeat for 5-10 times
2) charge your phone to 100%. remove plug, shutdown. Replug it, wait till the light goes green, boot up, charge to 100%, remove plug and shutdown, replug it , wait till light goes green etc.... do the cycle for 5-10 times
I was trying to see how much I could get out of my phone. I used my phone as little as I could, putting it into airplane mode when I slept.
ROM and Kernel: I was using the latest build of Energy and Faux Kernel v.15 at the time of the picture
Using stock battery, unfortunately I do not know what the highest battery temperature is.

unfortunately, for this device, the screen brightness and dual-cpu takes up a lot of power... if you see the pic below, when you use your phone(screen-on/awake), the battery % left has a sharp drop
I know for my old phone, LG Optimus T, I didn't have a data plan... the phone had data off all the time, and I got days out of using it(phone calls, wifi/browsing, checking gmaps offline)... once I enabled a data plan, it got half (like 1.5 days instead of 4)
if you calculate your usage... its possible
24 hours * 50mAh during idle = 1200 mAh
2 hours * 300mAh/hour during screen-on usage = 600mAh
total = 1800mAh, the capacity of your battery

So if I use either of those 2 methods above, is my battery 'cured" of the 100% to 90% fast drain? Or do I have to keep doing it over a period of time?

bump charging only helps you for that one time... you have to do this every time if you want max battery capacity
the problem is 2 things
1) the hardware/software is configured to maximize battery lifespan, meaning to slowly charge it and not go to 100% (high voltage, damages battery)...
2) the hardware/software is poorly coded, can't read the battery voltage properly...
either way, doing this means you are forcing current into the battery every time... your battery will hold less charge in a few months if you force it to full everytime... so you have to get a new battery aftera couple of months or live with lower capacity
I will just try to observe it better tomorrow using all those apps. With much less usage (1.5 hrs of screen time), i only got 11hrs of battery life. The screenshot below is for those 1.5hrs f screen time... I dont use jd and got email sync every 1 or 2 hr though....
Sent from my HTC_Amaze_4G using xda app-developers app
I tested the idle-deep sleep capacity of the phone...
got 21 hours idle, 17 minutes screen-on (minimal use of phone) with 50% left
here is my phone with data and auto-sync ON, I got roughly 10 emails(all received during different times), had about 10 minutes of phone calls
NOTE: around the first part of the graph, you see the %-left spike up... I rebooted my phone then... and you can see that the battery-monitoring software/hardware part recalibrates itself to the real value
NOTE: cell standby-time of 21 hours used more battery than screen-on of 17 minutes.
When I used the phone for another 15 minutes, screen used 35% of battery while cellular standby dropped to 22%
tl;dr, using the phone, especially the screen, kills the battery a lot more... not using the phone = lasts a long time

I guess after using all those apps that you mention, I can kind of see that Amaze battery is just way worse than my G2. I was pampered with my G2 battery life for a week and now I realized how bad Amaze battery is. lol
I got 11% left after 12h 15min. That's about 1550mA used (I use stock battery).
almost 3 hours of screen time (3*350) = about 1050mA
25 mins of phone call = ~120 mA
about 8h 45 mins of idle = 360mA
So, yeah, it summed up about right this time (more accurate compared to my first result where I think I got a rogue app)...
**I am eagerly patiently excitedly waiting for a fully working stable CM9 by sport :angel: **
On a side note, just wondering if anyone know if galaxy s2 have better, worse, or about same battery life? I am just curious since s2 is supposed to be amaze rival at t-mob....
Here's mine
Rom: Fourth Bar Jellybean Fusion
Kernel: Faux's Kernel, latest edition [August 15th]
Average Temp: high 90's
Average Battery Life: 5-6 hours.
Realize that what you do with screen on makes a significant difference- If I play organ trail(awesome zombie game styled after old school oregon trail game) I can play for a long time with little battery drain.. but it is a 2d game, and not going to be very processor intensive. If I play final fantasy 3, a 3d game, wow.. battery will drain much quicker, but then again, it IS a 3d game, and processor intensive. So HOW you use your phone is even more important than the screen on time.
With the latest faux(17) kernel, and 2-3 hours of screen on, the last few days I have 45% battery left after 15 hours since unplugged. Maybe 30-45 minutes was organ trail, but not much other gaming. The only changes I made, were made to the kernel, which I posted here(be aware that making all those changes will create some small lag changing screen orientation or opening app drawer, but haven't noticed anything else). http://forum.xda-developers.com/showpost.php?p=30298629&postcount=4
I also underclock to 1.2ghz- this doesn't create any lag, and no game or app I have used seems to work ANY better @1.5ghz than it does @1.2ghz. The main difference is the voltage it uses at max speed will be less @1.2ghz.
If you have weak 4g signal, there is an app i recently posted in some thread that puts it on 2g while screen off.. that has helped a lot too. If you have constantly good signal, then it won't make MUCH difference(tho 2g does drain less than 4g even with good signal), but it takes up to 2 seconds for it to switch to 4g after screen on. I can wait two seconds before opening an app, I don't care.
I assume you have used betterbatterystats to see what apps keep your phone from deep sleep, under partial wakelock?
And when I get obnoxious drain, but NOT because the phone isn't going into deep sleep.. I turn on the logging of an app called currentwidget- it can actually measure the MAH used while using specific apps.. the app itself can cause a bit of drain, but you'd only use it long enough to see what app is so battery inefficient. I have more about how to use that under battery savings part of the bible in my signature.
Edit: And I consistently get battery temperature of 77.7-77.9F, I always have, no matter the kernel or rom or settings.. perhaps it raises a TINY bit when I play some intensive game, but never noticeable. I am using an anker battery tho, so if you are using stock, perhaps that is a factor.

Whoa... I suppose there is someone out there with similar condition with mine... I almost thought I am the only one

Good to know that. I used a different app to check the current mah and it seems reasonable. I forgot to use better battery stat; but, based on cpu spy, the deep sleep time seems about right... I haven't updated my kernel to v17 (still on v15) and haven't done any edit that you mention since I was still switching roms to find the ROM that suits my need. I might try to do those stuffs today and hope for the best.
And btw, I am kinda jealous with your battery life... 45% left after 15 hours unplugged and 3 hours screen ON
I might get similar result; but my battery left will be 10% and those screen on are mostly on flipboard, xda, and browsing....
Like right now, 6h 10min unplugged, 40 mins of screen on (xda & flipboard), and I am down to 66% :crying:
**On a side note, I just get my hand on gs2 and I am just curious to try and see how good it is since gs2 seems to be such a hyped up device compared to amaze.... :laugh:

Just checked my usage. I'm sorta similar to yours in terms of screen on time. 11 h 43 m since unplugged, 39 min screen on (facebook, news, texts) and I'm down to 62%. My screen on time isnt that high, yet something else is draining my battery.
Awake time is 1 h 44m. Lots of Alarm Manager partial wakelocks. need to figure out what's causing those

*TRICK* The Proper Way To Obtain Peak Battery Life!

So I have been testing the LG Optimus G E970 AT&T for quite some time now.
What I found is stock, non-stock, custom kernel, stock kernel, custom rom is it doesn't matter what choice is made, Battery life sucks. Wouldn't you guys much prefer a couple days compared to a half a day?
The absolute best way to obtain good performance at least acceptable performance and get days and days of battery life is simple. Primarily it has to be Cyanogenmod 10.2.0 Official Stable Release on stock kernel.
Cyanogenmod 10.2.0 by stock though gets about 15 hours as stock does. Though there is a couple cool things to do to get insane battery life. First is proper calibration by draining to absolutely dead. In terms of Android auto-shutdown, then boot up to recovery screen or bootloader. Let it sit on the bootloader until it's dead as a door nail. Prepare for a device which may not turn on with or without power period. It would appear bricked/ dead, however its far from that. This is a force calibrate procedure and if it doesn't power on or respond to power after that it's clear the battery is heavily damaged from improper charging. I had to remove the nano screws on bottom, and nano screws holding the battery ribbon connector. Which I left the screws out for easy quick battery access in the future. I had to disconnect the battery ribbon, then plug in power and watch it start up to lightning bolt charging mode. I then unplugged and plugged in the battery ribbon. This time it started charging from absolute 0%. I charged it from absolute 0% to 100% without stop. It will then be properly calibrated and will stay that way as long as you charge appropriately when it dies or gets below 5%.
You must leave developer options disabled as well as it'll force interactive as governor. Range by stock 384-1512mhz. You will need two apps one is DS Battery Saver and set it to Slumberer, and in options settings deepsleep uncheck check background data and battery triggers to ignore. This alone will force 24-36 hours with full 1.5ghz performance but will lose 25% per hour heavy use as normal.
Next step will be download MULTICORE CPU CONTROL FREE. Set Core 1,2,3 to always disabled and set Core 0 to max 702Mhz via custom profile select profile save.
The difference between running on a single core at 702mhz vs all 4 at 1512mhz is a delay in milliseconds.
1512mhz on all cores give less than 100ms delay of response and gives horrible battery life while in heavy use. It will lose a couple percent per minute while in use.
702mhz on one core gives roughly 750-1750ms delay response. That means it is 17.5 times slower though the battery life is insane! Even my mind runs fast and I can deal with that delay no problem, even with how picky I am about snappyness.
Now on every boot you pretty much need to go to the profile edit and re-save if you set auto apply on boot up it'll still ignore it. So edit profile save on each boot and check time spent in states to make sure only core 0 is active 100% of the time and at 702mhz max.
So far I have achieved 1% loss per hour while in heavy use. Which should in theory approach and exceed 99 hours on battery without charge. However realistically it'll achieve now more than a day and could last closer to a week when idle!!!
Anyway Good Luck Guys!
whoa what? can you tell me your findings thus far?

The CPU Profile disabling cores does improve battery life but I just got sick of messing with the app. Developers should create an AROMA Kernel installer to do just this without toying with it every boot.
So far though I'm getting no less than 48 hours out of it now... Not bad but I'm gonna buy a new phone anyway the in call volume is horrible and clarity of both ends is horrendous.
So I'm gonna buy a Galaxy Note 1 or 2 probably one because it's less than $100. Note 2 is like $125 but I'll be okay with a dual core for $90 and 5.3" Screen. It's also the Mass Storage will be way better. The E970 hates my SD card it doesn't like it not one bit plus the Storage Configuration on E970 is straight up stupid.
