Think I need to slow down a little...flashed 3 different kernels since yesterday. As a newbie to this and trying to determine what works best with Rom I'm running, how long should I run a new kernel before judging performance? Specifically battery wise. Should I go through a certain amount of charge cycles or make judgement over course of couple hours use. Have been fully charging and clearing battery stats after flashing kernels. Haven't fully discharged and recharged to full with any. Not enough time. Lmao.
you arent crazy, i do the same thign with kernels. but the key is to be patient. the way i do it is this. i flash the kernel, then load current widget and system panel. let the phone sleep all night, and record idle current readings and let system panel monitoring do its job. then analyze in the morning.
i look for a good constant 5mA drain on current, and far under 1% cpu usage on system panel. more like 0.2%, with only 3 items showing up in the list, system, system process, and current widget (of course lol).
that's an acceptable kernel in my eyes.
Thanks Roger, I will try your method...more scientific then my method. I'm pretty lucky that I stay on 4g all day in my area and WiFi at home, have been looking only at display time (basically internet, mail and work web usage). Best display uptime so far 4 hrs. 15 minutes and worst 3 hrs. 45 minutes with different kernels I've tried. Was only getting 3 hours max display time with stock so I'm happy. Your method will give me some more clarity with what is happening during down time. Big difference in how some of the kernels feel on the phone and that matters to me more then the extra half hour difference I get between kernels. Laptop collecting dust since tbolt purchase. Appreciate the help.
Hey guys,
How much battery life do you get on your X2?
I just installed CM7 and I'm down to 60% after 5 hours of LOW use :/. Could I need a new battery?
Are you doing anything with the settings of the CPU, such as setting minimum frequency, keeping both CPUs online at all time (this might be set via tweaking scripts)?
In fact, ARE you using any type of tweaking scripts (V6 Turbocharger, speedy, etc)?
I don't use any of them and my battery life is pretty good. I also have an extended battery as well, so that helps.
Let the ROM settle in. After two days you should get a better picture of what it's like. Don't forget to do a battery calibration. I haven't even done that yet and have been lucky enough to have great battery longevity. Can also look into managers like Juice Defender. There's also another app I have used in the past that can limit when an app can run. Like limit Facebook from always running in the background and syncing for data. Ithink it'd LGE or LBE security?

Are you using the beta and not the alpha? The alpha has a problem with running the CPU at a high percentage when it shouldn't, which cause the battery to suck.
It is possible that you may need a new battery, but more likely is that the X2 simply has notoriously bad battery life. There are, however, things you can try to help. Go to your settings app, scroll down and click on "applications", and from there, open "running processes". Check out some of the processes. There may not be any, and if you see processes running for games or apps you haven't used in the last few minutes, it may mean that they are constantly running in the background. In that case, you may want to consider uninstalling. Try to use wifi over 3g wherever available. Screen brightness is a major battery killer, and as such, may want to keep it on the lowest setting; I've found it to be the most noticeable improvent in battery life. People are going to tell you to calibrate your battery, but I've done that many times on 2 X2s, never seen a difference. My friends and I agree its just a myth, but there's no reason not to try.
Honestly I don't know squat about batteries, but I remember hearing that the voltage of our batteries is 4.2 volts. If that's a measure of capacity like I think, you can try the app "battery left", which I believe has a voltage meter. If its less than that, maybe you should consider a replacement. Please don't take my word on this though, I can't confirm any of this to be true lol. Maybe someone else can offer their opinion on battery health.
This whole post probably seems like a big collection of thoughts. I'm tokin' right now, took me like 20 minutes to type this.
Hope I could help
To add to theredvendetta's comment, if you have your email set to check for messages, it can really have an effect on your battery. If you set it to never check, I'll bet you will see a difference.

I am using the Beta.
@theredvendetta: I installed the Battery Left widget, and when I go into details it's saying some interesting things.
I'm at 50% battery right now. For one, its saying my battery is at 3787 mV. 3.8 volts I would say considerably lower then the 4.3 it should be. My battery is only ~6 months old, but, for 4 of those months it sat unused, uncharged, and in my hot/cold car. I've only run it down a bit and charged it up 4 or 5 times this week since then.
It is reporting "battery health" as good, but idk.
Under "Accuracy" it's saying the charge reading is "Inaccurate" and the bar is totally red, indicating that the estimation of charge is very inaccurate.
Where can I calibrate the battery? I'll look around under Settings for now. EDIT: It's likely I was only around 60% charged or so when I installed the rom.
And as for background tasks, aside from the default stuff and my few widgets (not a heavy user of those) there's just Facebook+Words with Friends, Songbird, GO Keyboard. Not too terrible, I think.

I probably should have said this to begin with, but when I was talking about the voltage, I meant 4.2 was the charge when at full charge. I can see I worded my original statement poorly, apologies. Try charging up to full, and then check battery left.
When it says "innacurate", its reffering to the battery percentage reading its giving you. When you have cycled the battery once or twice, it will tell you it is "accurate", and the bar Williams turn green. You may notice parts of the bar turn green while first using the app; this means its picking up readings for the percentage of battery you're on at the time. I mean if you're on 50%, it will soon turn green halfway through the bar. After you have completely cycled the battery once or twice, it will stay green and accurate until you reset it or uninstall.
To calibrate the battery, you have to enter Android recovery. I can't remember 100%, but I believe that you hold the up volume button while booting up the phone. It may be down, you can try both. Hold it until you see text pop up that I think says "fastboot". When you see this, let go of the volume button, and now hit volume down until you see text that says "android recovery". If you accidently cycle past it, keep clicking volume down, as the list loops. When you stop on android recovery, press the up volume key. After a few seconds you will see a new screen with an exclamation mark. Press the up and down keys at the same time. A list of options will now appear. Don't use any of them unless you know what you are doing. There should be an option called advanced or something similar. Cycle to it by using the volume keys, and hit the power button to select it. There will be an option to calibrate you battery in there. Itbwill take a few seconds, and after that, return to the main menu and reboot the phone.
Good lord that took me ages to type. There's no hope with dope kids.
I feel like a broken record, but again, battery calibration does not do anything. If there's a chance the meter is off, just charge until your battery's voltage levels off and use the battery fully before charging again.

I agree with you. He asked and I answered. 'Sides, there's no harm in trying it, as there are no negative aspects to it.
Im running cm7 and the only mod im running is the 8 touch points. I do have my screen set to the most dim setting thoough. My phone gets unplugged at 5:30 in the morning though out the day I'll talk send some text might play a few games and usually be on the internet about a hour or so. When I get off at 7pm my battery is usually anywhere from 75% to 69%. A few times it has gone 18 hours and only been down to 52%. Give it some time, CM7 has by far the best battery life that Ive seen for this phone.
Yeah, after clearing the davlic cache and going through a few charge cycles, it seems to of improve greatly.
I'm running CM7 and my phone has been unplugged for 23.5 hours with medium usage including 72 minutes total voice call time and I'm currently sitting at 23%, hence my signature lol and this is a stock battery.
SBF'd from my tasty X2 MAXX
give it a few days but cycle it hard, like don't plug it in until you're below 5%. I have the BH6X (1850mAh vs. 1600mAh) so it's not much of a jump in capacity... your voltage should start out right around 4.2v and drop to about 3.5 when it's close to dead. My phone sucks at telling me how much battery is left, it always has, I typically run this thing dead every day, but some days I'll have upwards of 40% left (voltage is still above 3.8v)
I honestly don't even pay attention to the percentage 'cause I can watch an entire episode of beavis and butthead in HD with the brightness all the way up using software rendering (more power consumption) when I'm below 10% and it won't shut off on me.
it takes me almost a solid two days to kill my battery and I've been on CM7 Beta for a week as of yesterday. at first my battery life was absolute crap, but it has improved... every time you wipe the dalvik it'll take a solid 2-3 days to rebuild it. that uses much more power.
I am prepping for CM7 now. With my mostly stock X2 using Juice Defender I am getting about 1.5 days between charges. When I charge I am about 20% or less on the battery and this is with mostly lite usage. I expect once I make the switch it could take up to a week for everything to level out as it will have to synchronize many things because it will be like having a new phone. When my X2 was new it took about a week to settle in and stop the random crashes. That was also about the time the battery improved from about 1 day between charges. I will write back in a week or two once I have my phone switched and stable.
I used juice defender for awhile but I realized I was really only using it to control data. I just keep a data toggle in the notifications bar. It's really not that much of a hassle to switch it off and it reconnects fast enough. Saves quite a bit of battery power. When I was doing that with my extended battery on liberty I could get about three days.
I am actually impressed with my x2's batt life (although it is a brand new batter when I got the phone a few months ago). I used to have the HTC Desire, and it wasn't the greatest with battery life. My bone stock x2 didn't have the greatest batt life when I first got it, and still wasn't a whole lot better with cm7 installed. But now that I have installed miui on it, and screen brightness is about 70% constant, with wifi ALWAYS enabled. I am going on almost 24 hours now (maybe more??) and I am at 57% with little usage. I've used the phone maybe 2 times today for a total of about 10 minutes talk time, I have no 3g/data, other then wifi when I am at home, so I'm sure that has alot to do with it.
Another tip, that probably everyone already knows, and some people say it doesn't matter, but it seems to for me. ONLY charge your phone when it is less than 10% left, and then make sure it is charged for at least 6-8 hours before you unplug it. I know they say the newer batteries are not effected by this but my wife had the HTC Hero (worst android phone ever IMO), but she would charge it every chance she got, even if it was at 80%. Now, the phone is lucky to hold a charge for 5-6 hours with NO USAGE at all (except wifi always turned on). Granted the phone is older than dirt, and so is the battery, but still. My desire still holds a decent charge considering how old it is. I can get maybe 14-18 hours with no use on it (or very little use) with wifi always on (granted, the phone is bone dead after this time though).
I just altered the cm7 performance settings... back to normal. This combined with a custom juice defender ultimate profile has easily tripled my battery life..

Yeah I've seen nothing come from battery calibration. I have problems with my meter some days draining really quick and some days just normal. If it's bothering my I'll do a reset and that will usually sync it up. I'll try the charged voltage level off and empty thing and see if that helps.
Thanks.
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.

I leave my phone on all night since I use it as an alarm clock, if the battery is relatively full at night I don't charge it. I just turn on airplane mode, silent mode and wifi, I have it underclocked to 384 also. It barely drops any over night!

I use mine for an alarm every morning, but I leave it in 4g and turn the screen off. It uses virtually no battery at all overnight and has never failed to go off as set since day one.

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
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 ).

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.

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?

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?

Maybe you should try to mod the Atrix Lapdock... if it works, you get a larger screen and a 35W battery

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.

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
Can anyone with an HTC one tell me about how the battery life is on yours and what helps make it go longer? Because I would call the battery on mine awful.
I would recommend that you install an application from the Play Store called "BetterBatteryStats". This will enable you to closely check what application uses the most battery, how long your phone is in deep sleep for and much more.
Charge the phone fully and after about a day, or until it almost dies, export a text file using the share button and upload it onto here and we can have a look at what is using your battery.
Just out of curiosity, how long does your battery usually last? Mine lasts 2 days on light usage and 1 day on heavy usage.
It's awesome. I'm running arhd with greenify hibernating all my apps. I get like a day and a half of battery time.

thats bad...it should not get hot like that...any device lol...even on standby, for a device to get unbearably hot is bad ... do you have a lot of chat apps and background apps running? like apps that require push data services and etc?
Nothing. I run a lean system. I close all apps and I'm using the stock messaging app with the stock keyboard. I've concluded it's just that this phone is a piece of ship board.
With respect...

My guys are getting upwards of 30+ hrs and 3hrs screentime with 4.2.2....usage may vary....
You could put your phone in power saver mode. I haven't bothered with it much, but those who have say that it doesn't impact performance in any noticeable way. I tend to have 1-3 hours of screen on time, depending on the day. I've never had any issue getting that with this phone, at least not yet.
As someone else mentioned, it does get quite warm to the touch, however. Never to the point where it's uncomfortable to hold, but enough so that it bothers me. I think it's just because in the back of my mind I know that, in general, electronics getting hot = bad. Yesterday my One got warm in the car while I was using GPS to navigate with it and the sun was just pounding the interior of my car. So I held my One up to the vent and blasted it with the air conditioner from time to time (i.e. not while driving, so spare me the lecture). Seemed to cool it off pretty well
Perfect rom
I have been using the RayGlobe Rom 6.0 and the battery is more than adequate for me and runs cold. Lots of mods and themes also. Might give it a try.

With stock sense, my battery was pretty bad, to the point where I was pretty worried about having to get a different phone as it wouldn't last a day. But I put CM 10.1 on here last night, and it has been pretty amazing today.
I actually just picked my One up this last week and have been running battery tests with moderate use throughout the day and it can easily last 20+ hours (I didn't have time to let it go for a full 24). Maybe i'll do some heavy use tests and see how it goes.
I too am having battery issues... One day the battery last forever, the next day it drains quickly. I recently installed cpuz to see the max speed of the cpu when power saver mode was on. The max speed I observed was 1134 ghz, however I again checked the cpu speed after I rebooted my phone (with power saver still enabled) and cpuz now was indicating the cpu was running at full speed 1728 ghz. I turned off power saver and then re enable power saver mode and then cpuz showed the cpu to be throttled again at 1134 ghz. It appears (at least on my phone) that power saver mode does not automatically start after a reboot even though the powersaving mode was left on prior to reboot and the the phone shows the power saving symbol as active after reboot. Would someone test this scenario on there phone to verify the problem exist on other phones?
I converted the AT&T HTC One to full Google Edition and my battery life is solid. After 10 hours of usuage (BT on & connected, Wifi on & connected, Exchange email on push, 2h of screen on time, 2h talk time ...) I get to about 20-30% left of battery.
Good enough for what I need compared to my retired GS2
