I am waiting for the OTA update before I root my HOX but I am still trying to calibrate the battery now. I disabled fastboot and I'm running JuiceDefender Ultimate.
When the battery reads at below 5% the voltage is around 3570mV. At 100% I'm reading a voltage of around 4185mV. Is this normal? What sort of min and max voltage readings should I be seeing?
I'm getting approx 12hrs (3:45 hrs screen time) before charging (that's with running Shadow Galaxy live wallpaper, and watching a 2hr movie on MX Video Player)
Thanks in advance.
The phone uses less battery because its turned down or off features such as syncing also with li-poly batteries as they drain their voltages dies down with it. Normally is a Mv in difference. Like with an electric car or RC car when the battery is lower than 5% they too slow down. The amperage pretty much goes out the window.
But for the phone HTC has a pretty insane battery management system, its normal. At 15& the iPhone mv would dropped about a whole volt as well.

Oh okay cool, thanks!

So I pulled my phone off the charger at 6am today, when I got home from work at 5pm(11 hrs later), I had 60% battery left.
weird thing is, I just noticed my brightness has been at 62% all day. Lowest being 11%. I usually keep it at the lowest brightness but I must have tripped it up somehow.
That is amazing battery life given the usage during those 4 hours. Texted, played angry birds, emailed, all of it all day.
I'm running Serendipity 2.0 with glitterballs kernel, 1.2ghz no uv. 1009 and I got it on Amazon.
Maybe the brightness keeps the cpu running at a speed that better utilizes the battery drain?

I think it's just recalibrated device eg batterystats.bin
I'm on an EVO 4g (but I don't think this is phone-specific) and according to the battery monitor widget app (and confirmed by touching the back of my phone), my battery gets pretty warm when the % remaining gets lower. In fact, at 2% battery remaining (a little under 3500 mv reading), the battery temp reads over 40 degrees C.
Is this normal or is this a sign I should exercise my warranty and get a new battery?
Oh and yes its a stock battery.
Normal

I recently got a Sensation, flashed Inquisition, Sense Faux Kernel, undervolted about -50 to -75, and bought an 1900mA Anker battery, and after a few days my battery life can last almost the entire day. For example, yesterday it lasted 13 and a half hours with 2 hours and 30 mins display on (which was about 70% of total battery usage. I have brightness at about 40%. What really gets to me is how the battery drains really fast once it hits 20% or so.
I've attached my battery usage from being unplugged for a few hours.
try bricked kernel. it using 25mA when in sleeping mode no need of any apps

I used to have the same issues earlier.
The fast draining from 20% is because of
Improper battery calibration which needs some time to asjust(it took 6 cycles for me).this I can confirm you because once my phone switches off because of no power left and when I plug on the charger the battery percentage goes upto 15% in just 1 min also this fast 20% drain is always attributed with last longing 100% change ( I mean battery stays at 100% even you've used your phone like for 30min with screen on all the time)

I flashed Bricked kernel last night and unplugged my phone at 4am. Currently, after being on battery for 6 hours 48 mins my battery is down to 57% with only 15mins of actual use/display on...I have system tuner and battery widget and can provide logs if anyone would like to further assist me in pinpointing why my battery sucks.
Is there an app or process keeping your phone awake or using CPU in the background? System Tuner Pro can help you diagnose this.
Also, try a clean install of your rom, stick with stock kernel and check. Re-download your apps one by one from market, checking for a few hours after each.
It should be possible to get standby drain of 1-2% ans 1.5-2 days battery with moderate use I do.

More info. I streamed music for maybe 30 mins.
Do a battery calibration like Mike's 1986 thread in ARHD 6.2.2
it will calibrate ur battery like u will some improvement like I did 2 days ago

Looks like attachment uploading is broken. Anyway, A few changes I've done have improved sleep time, but my phone still looks sad compared to my girlfriends iPhone 4s battery life (17 hours on, 2 hour usage, at 62%).
So I just started using Matr1x kernel and it has to be the best I've seen so far. But I'm wondering about the battery life extender in nstools. Like say if I set it to 110% battery it will charge to 110 giving me extra battery? Is there any harm done by doing this? Tell me exactly how this works
All I know is it limits the charge level of the battery. You can't charge a phone battery past 100%. That's dangerous. The Nexus charges to about 96%. Anything that posts 100% charge is purely cosmetic.

So your saying for the best of my battery life i should set it to 96% limit?
Your idea was.... no offense, kinda funny, it's just like you have a cup that has capacity of 500 ml, can you put 550 ml water in it?
And by battery life it means battery's physical life, not mobile use time.
As for a Li-ion battery, charge to fully 100% or deplete to 0% will reduce its capacity, and this mod was meant to set Max charge under 100%, for me I usually set to 97%, actually as I have 3 battery, I can even make it 95%

Which should be max. battery voltage ?
I have never seen voltage greater than 4.170 mV at 100%, according to Battery Monitor Widget.
My Desire HD instead, reaches 4.201 mV at 100%.
Is this normal ? if not, what should be done ?

Volts are not overly important. It's the mAh that matters. My phone's battery has gone from 3,600mV at 70% to 3,755mV now at 37% (and rose to 3,759 and dropped to 3,756 while I was typing this). My old BlackBerry Torch 9810 used to do the same, my Wildfire S before that. As long as the Elvison battery widget (get it if you don't have it) tells you that your battery is in good health, then you have nothing to worry about.

Thanks for your answer.
I agree, it' s like this during operation.
My problem is the max. voltage when fully charged, which is low compared to the max. voltage of my Desire HD.
