SetVSel vs. juice defender ?
What you recommend?
I've only used setVsel and i find it very easy and functional.

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.

default settings, only changed value [email protected] to 1000 MHz and run stability test for 30 Minutes -> without a problem and only 34°C
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 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)

Let's see how long this puppy can go without charging.
I'll keep its usage only to phone calls and messaging (which is a lot). It'll be my main phone obviously (and I can't turn it off).
Settings:
a) devoid. rom (link)
b) wifi, gps, 3g, mobile data - off
c) brightness @ minimum
d) auto-sync - off
e) underclocked & undervolted @ 480Mhz (min: 122Mhz)
f) governor set to conservative (still thinking about it)
g) hardware acceleration - off
h) watchdog lite installed (to check for apps gone berserk)
i) load monitor installed (to check for kernel loops and wakelocks)
j) airplane mode when sleeping or at classes, exams or hospital
k) red colored wallpaper (red is in the lower spectrum of visible light EM: higher wavelength, lower frequency, lower energy, lower battery consumption?)
Did I forgot anything?
unplugged
03h30m GMT+0, 12/01/2011
99% battery left
How about the Screen Filter???
LINK AppBrain
It's worth to use it also??

You really DO get bored!
You don't seem to have forgotten anything. I don't know if a red wallpaper really helps, since the big consumer is the backlight which you already minimized.
Good luck, I'll be checking this thread to see your record and I hope you are keeping track of how much talk time you get during this experiment.
What about ringtones? Are they on ?

i just did it to my phone.. but with the original stock lg rom. i set all settings to default , no wifi, no gps.... just calls and messages and a little use of mp3's about 1 hour.
the battery is 1%
and i have done 3 days and 2 hours.
1.31 hours of phone calls.
just when i need it..
i had unchecked all sychronization things, apps and i set it to gprs..
without turning off or airplane mode
the brightness was the default.
i thing it can be last longer..

Hmm, well the brightness is already so low :x
Anyway, I have to restart the test.
Underclock and undervolt seems to consume more battery...
I'll unplug @ midnight of 13/01/2011, GMT+0.
Keep us posted.
I've made a Test with Javali, using the LG P500 just for Calls and SMS, and after 48 Hours i still got 60% of Battery.
14 hours ~ 94% battery, without underclock/undervolt or using airplane mode.
i had cpu tuner and it respond so freaking slow...i wanted to save battery but instead ive managed to drain it more faster....

Intresting results, not bad for a smarphone! How would you rate your device responsivness do, was it realy sluggish since you undercloaked it?

I didn't underclock it.
I did at first but consumption was higher so I put it back to 600Mhz and restarted the test.
So, by extrapolation, we can assume around 6 days of battery life. Still, without knowing the talktime this is inconclusive.
@Noejn
What about undervolting keeping the same Mhz, is that possible?
@
I never tryed draining compleatly my battery because i keep on pluggin it in my computer to test stuff, but I would be happy if my phone could last aprox. 4days.
@noejn
I read in this forum that you don't have a lgp500. Then how come you are testing its battery and other things.

Have you tried re-calibrating your battery? Made a huge difference for me; it's good to do especially with a lot of ROM flashing, but even with just one it can throw your battery calculations off.
FYI follow the instructions to the letter, otherwise you might as well not do it at all IMHO.
I had the same issue using GSB 2.X. Switched to OMGB 1.1.1 and i now get 15 hours with moderate usage and no tweaks.

I've gotten over 30 hours before with GSB, immediately after a recalibration.
Your best bet for battery life is setcpu settings. As long as you're using froyo and gingerbread you'll get a boost.
I suggest Tazz as his ROM's have always worked for me. My setcpu sleep profile is:
min 19mhz
max: 480mhz
governer: smartass
and in advanced settings I have:
polling interval: default
Whatever the next one is: 98
Ignore smart or hwatever the third one is: 1
bias: 4
edit: With this I can get a good day or two of moderate use.
I found on GSB that that 19mhz is too low and the phone does not always wake from sleep. I followed workshed's suggestion of min 480 mhz with max 710 using CM7's CPU settings and all worked very well...that is until 2.0 when battery life went to hell. I recalibrated but i think the problem was my exchange mail app.
Oh, and with smartass you shouldn't have to set sleep profiles. Supposedly it's "smart" enough to figure that out
You can also try collins battery tweak, I use it on tazz gingerbread and it works awesome my phone used to die pretty fast before I tried it and now that I put it back on my phone I am very glad I did.
Im running GSB 2.8 but for me, all seems to be going well.
In one day, off a single charge, I've gone 12-14 hours at a time!
Make sure you always charge correctly, and don't abuse the phone's battery all the time!
Been trying out various ROMs and lately, I've settled on FroShedYo's Final V11 with CM6.1 as my everyday workhorse, stability over speed, and with a bit of battery calibration - getting an average of easily 20 to 30 hours off a full charge on OEM 1500 maH battery originally for the HTC Ozone (so it's about 15% higher capacity than stock's 1300 maH, which I keep as a spare/backup.)
With a bit of tweaking on CPU clocking (Ondemand), turning off vibrate & alert sounds/LED's, and email checks every 60 minutes (1 account only + Gmail pushed) and minimal widgets open, etc. - I can leave the house at the beginning of a long day, go about daily business, voice calls, check email checks, quick news & weather update, etc. and still have 25% to 50% battery life after an extended 12 to 15 hours day on the move, depending on how the device is used. I get a poor 3G signal at the house flipping to 1X often & back, and wifi OFF on the road (BlueTooth ON for driving but no Maps/NAV (ON at home.) In short, plenty of variables on how the battery is getting drained - in standby mode, clock speed is lowered so I could still be over 90 to 95% battery after 2 years but it will slide downward with active usage. After wiping/flashing & reinstalling all the APPS & fine-tuning the settings, I do a NAND backup and then do the battery calibration - and after 1 full cycle, I've been consistently getting these standby & usage time - which I can live with (C2C flashed and extra goodies on a 16GB SD card.) Yesterday, it was showing over 50% after 15 hours of light/moderate usage.
I've tried the latest nearly finalized GSB/GB Roms & variants, they are faster & fancier, but FC's, GPS issues & other minor bugs plus "not as good" battery life had pushed it back to 2.2 OS on the Eris. OMGB 1.1.1.1 and the Condemned CM7 just out this week are pretty cool - but battery life really slide quickly - unlikely to see more than 10 to 15 hours of usage out of a standard/non-extended battery.
The other one that I like is the Nonsensikal 2.2.1 ROM, troublefree, stable & reliable - the edge on battery yielding to FroShedYo's version ( keep that on another 8GB card along with the newest GB releases for "playing")
Otherwise, the xtrSENSES 5.x and xtrROM 5.x are fine as well for everyday use - performance & battery life-wise over the latest stock 2.1 ROM.
Those are my two cents for what it's worth, great work being done here and it's giving new life to the Eris, not quite EOL for some of us - played with the TB in the store, nice big screen & fast, but I'm not about to wear a "brick" phone going out on the job with an extended/bulky battery just for bragging about 4G/LTE. Mobile devices have come a long way, I still got my original analog MicroTac XLT with a 2200 maH tipping the scale at 10 oz in my bottom storage drawer.
On the sideline for a "polished" GB/GSB ROM with the bugs resolved and better battery life, and I'm off to flashing it on my spare SD to test it out. for the "adoption" usage.

6 hours wow thats bad man. i get 30+ running gingertazz
i leave 3g off till i need it and usally just use wifi if around wifi spot
do a recal. like people suggested
So, I went to sleep at full charge, took it off the charger to see how my drain was....I woke up 6 hours later and it was at 64%. I took a look at partial wake locks and it looks as follows (I can't upload .png from my phone)
RILJ (Dialer) 205s count 2178
juicedefender 3019s count 1570
Alarm manager 1543s count 1320
Google services event log also has a pretty high count. I ran the "battery fix" and all that jazz,recalibrated my battery,not sure why drain is so terrible?
Could someone please help me out?
I am running cm7 with faux 0.2.0 1.3 kernel. I have it undervolted and profiles so it never goes above 1ghz unless on ac charger. (456 when screen is off)

I'm not sure how much it helps you with your issue, but for me JuiceDefender works very well. I would otherwise have a multitude of data sync apps such as Gmail running, and this limits it while periodically enabling sync.
Start tweaking what apps are using data and the battery life will be better.
I have had a problem the same where I am not so sure juicedefender is helping because I tend to set my phone on the desk when I do homework and the screen comes on after I put into sleep mode and then no more that 5 seconds later it turns on at about 25% screen brightness then jumps to 100% them dims to 25% then goes off, all in a matter of between 10-20seconds. I loom at the battery use area in settings and standby is at least 40% & display is right under and idle is next. my settings that I think may be causing this are the mobile data where the autosync is set at enable (in juice defender) & I tried ping but it does the same thing. I just want to know why the screen comes on ever 5 seconds. I don't know how to contact the developer to try and resolve my problem. I am actually on a thunderbolt but that shouldn't matter. I just wanted to reinforce that "i'm not sure juice defender is working as I get about the same battery life".
Xoom Xoom
I get double the life out of the same roms. I'll try a rom for a day then run juice defender and get a day and a half. Depends on how you have defender setup. The only thing I don't like it doing is disabling my wifi as It sometimes won't reconnect back unless I manually do it. I think setcpu is a joke though. I had it set for 216/456 at screen off and it was running at 1200 for 1/2 the time it was supposed to be asleep. Then whne I opened it up...(Battery less than 50% stay below 1000) and the screen booted up 1300. So to me it's an extra service I don't need.
JD has always given me more battery life on any rom that I have tried.. I recently got rid of it and am trying out GreenPower. so far GP seems to work a bit better than JD. I get a bit more life out of my batter than JD gave me.. try green power out if JD is not cutting it for you.. GP seems a bit lighter as well.. so, could be overall why get more battery life out of it..
Zug
Juice Defender seemed to do little to nothing for my phone. I got rid of it and my battery life remained the same. I can't say the same for everyone else but what works for you might not work for the next guy.
All I'm simply saying is give it a shot and test it out religiously before you make a decision to use it or not.
Works for me another good thing to do if you use set CPU underclock the hell out of it when the screen is off not using it so why not

Not sure what else I should do here? Should I re-flash CM7 with the battery @ 100%?

Install the battery calibration app and see if your charge at 100% shows 4000mV+, if it doesn't, that means your calibration is off and you need to search for juggernaut's battery thread and follow the instructions on that to fix your calibration.

Barely saw any gain using JD...only used it on my Dell Streak though. The atrix will go 2 days if I need it to so I don't see any need for JD.
I m using JD for nearly 2 years now and I have to say that it DEFINITLY improves battery-life - just by letting it switch off your 3G when you don´t need it you save a lot of juice.
When I still used my Captivate as my DD, JD helped alot. With all the firmware leaks I was reflashing my phone all the time and constantly testing different kernels/roms/apps for battery life.
On my Atrix, it hasn't seemed to help nearly as much. Not sure why... SetCPU with faux's OC/UV kernel has boosted battery significantly though.
I got lots of wakelocks using it. For me it's better to turn off data manually.

Interesting. I'll have to try green power. JD said my battery multiplier was 2.10x when I used it. It could just be making that up though. I got 28 hours of life from the atrix and still had 40% battery left (moderate usage: frequent texting and periodic data+wifi usage, I think a 20-30 minute phone call too)
I swtiched to green power. Didn't notice much of a difference in battery life, but Gp is certainly a lot easier to use.
How you guys get even 2 days of battery??
I am tired of tryin gall the combinations of settings / kernel / ROMS nothing has helped till date.
I am not able to get battery for a complete day. Freaking it drains it off in 9-10 hours.
There are users who are getting 2 days of battery with wifi/edge on at all the time, with overclocked phone, and many other options enabled. But I am not getting any of these.
My usage includes
* 1-2 hrs of music
* 1-2 hrs of edge
* frequent texting but can be summarized for 1 hr in a day.
* hardly 10-30 mins of calls
* 10-30mins of games
CyanogenMatt 1.1
franco kernel 19.4 gbs v18cfs
InteractiveX 480-600 mhz
all this is normal and way below average usage but still I am not able to get battery life. I hate recharging the phone after every few hours. Have searched forums tried suggestion but nothing worked.
Maybe I am choosing wrong combination of ROM / kernel , I have gone complete clueless now, any help or suggestion is welcome.

It is because of usage patterns. Based on your usage, I think its normally for your battery to drain just like that.

Well theta because they are using the phone less often. You are wrong , wifi consumes far less battery than edge. Wifi on standby drains minimal battery.

It's mostly about background tasks. Install supercharger and a task killer to kill your tasks on screen off. Then disable unneeded autostarting applications with Gemini or Autostarts. This way I get about 1% battery for 4 hours without using my phone. And I strongly advice you to use 480/YourMaxStable with SmartassV2 as Smartass automatically manages the current CPU frequency. Your brightness should be between 25 and 50%. And also disable any unused at the moment radio (including mobile data).
how would I disable radio?
do you mean not using radio is disable it??
Well here's how my phone goes on for 2 days
android assistant app for cleaning memory every 10 minutes and for killing apps on startup
Advanced task killer for killing tasks(set on auto kill)
Antutu power saver which has some good features(puts phone on flight mode at night for few hours)
or use juice defender(has extra features)
try keeping edge/3g/wi-fi/bluetooth/gps off when not using(saves a lot of battery)
reduced brightness(40-50%)
and keep screen off when not in use
also keep OC freq at 729/480 its the best know OC for our phone performance and battery wise
and InteractiveX is well know for battery saving
(i prefer on-demand because of performance and gaming )
the above things help me use my phone for 2 days or i must say 1&1/2 day
with 4-5 hours gaming(3d HD games)
1-2hours browsing the net
few messages and calls here and there
on a full charge and normal usage at the end of the day i have phone battery at 40-50%
A radio is basically a wireless I/O device. GPS, Bluetooth, Baseband, WiFi, FM... - these are different types of radios. They drain power when powered on so if you want battery life you should simply disable the ones that you aren't using at the moment.
@viv_jen: There is no need to autokill every 10 minutes if you don't have unneeded autostart applications. Task managers also drain battery if used too often. It's also a good idea to use the long-press back key feature of CyanogenMod (It kills the currently visible task).
To pitch in my 2 cents worth,
I've found wifi uses quite a bit less than edge/3g data on this particular phone.
This phone has shocking battery life, even for a smartphone.
What you are getting seems about normal for your usage. My battery will be between 20 and 30% after 4 hours of music and 3g browsing. Once I stop doing these things it goes down at about 2% an hour on wifi, about 3% an hour on 2g, and 5% an hour on 3g. I ended up keeping my charge cable on me when I go places and actively use the phone, and "topping up" the battery when I'm sitting at a desk or whatever.
thank you guys for valuable inputs,
could the combination of ROM + kernel also help?
I tried cyanogenmatt + goldenleaf after some of the user suggested that it gives enough battery.
I also heard void gives a good battery.

@nogav: WiFi drain depends mostly on Tx (Transmit) power. Mostly we receive information from the internet (Which means Rx is way more important than Tx), so after running a few speed tests (Speedtest.net app) at each option avaliable at the Wifi Tx Power app from market I found out that internet speed at a Tx power of 4dBm is roughtly the same as for 32dBm. Also, our device only supports 801.11b/g mode, so internet speed isn't the best thing about Optimus One (Excluding HDSPA).
@droidevil: The thing that drains most battery is Stagefright. It is able to play 520p mp4 videos almost smoothly, but it is a battery killer. Hardware acceleration also increases performance at the cost of battery, but it is reasonably balanced. Other things that depend on roms: number of preinstalled apps. Deodexed apps load faster, and the less of them there are, the faster the phone boots and runs. If you have about 100-200 programs installed, Autostarts, Advanced Task Killer and Supercharger are likely to be used.
thank you guys for your useful information..
Just raised all urs thanks meter for helping me out..
Well I have installed android assistant set to auto kill on every 10 mins.
Installed gemini and stopped the apps which are set to open on boot.
brightness is the minimum
480-728mhz with InteractiveX
so far 12 hours have passed by and have 50% left
Normal texting, gprs browsing, music no games though.
Lets see how far can I pull it off.

Nonono, don't use autokill, they are just crap, not needed, they drain more battery.
I have installed void forever to see whether it helps in battery performance.
The ROM itself is very fast, just wondering which kernel will best suit the rom to give the desired battery performance.
Any suggestions please..!!!!!
My LG optimus v running iho cm7 only gets about two hours of battery through normal use.

I have read around that fserve's kernel also gives good battery...
IMHO, actually your battery drain is actually pretty good for a usage like that, I am using more or less the usage of yours and everyday I have to charge.
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.

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.

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
