Why in the world don't you charge properly the battery before rebooting the device ?
My HD always reports the right battery values because I don't let the battery drain that much, if you wan't the battery to last many months please don't let it drain so close to 30%.

Because I want to test the battery consumption of HD .
Perform a complete discharge, recharge fully and then test..

Also some of us have no choice,
My device never lasts a whole day,
The battery consumption on the device is very bad.

I have the same, when I reboot my HD.
The last 20% drain very fast to 0%

You should say: some applications I installed or functionality I have enabled are draining my battery badly. The device itself with the standard applications does not drain the battery in one day.
I agree that for example using wifi is a major drainer, but I do not beleive there are other devices out there that do it a lot better, like say continous wifi for two days...
Battery cosumption is always a problem in all devices. There is no single PDA out there that does not have a "battery" thread and how bad it is blah blah blah...
I can give you examples of devices that will be drained within a couple of hours, and the same devices being able to last for three weeks or more. It all depends on what you run and how you use it.
Your may be right or maybe not,
I think I'll un-install my apps and reinstall again with each new app being added one day at a time, to work out if any of them is killing my battery

A "normal" application doesn't drain your battery. By a "normal" application I mean something that you open, work on, and close it again.
You have to pay attention to applications, which are running in the background and/or are polling every few seconds something.

Hi,
the battery took long to reach 50%... about a day of heavy usage but after 50%, it took less den an hour of heavy usage to get to 10%. anyone experience this? or is my battery fautly? thanks.
i know that between soft resets my battery will change values, usually go up e.g. if its 40% when i reset when it reboots it will be 44%
i have the same issue here
but the battery last 2 days with me

Same here...on my device from 50 to 10% goes WAY faster than from 100 to 50%. To me it means crappy indicator. Must be a HTC problem, as my Prophet displayed similar behaviour.
This behaviour ("jumping" percentage after power-off) is completely normal, but the explanation would be very long.
Short version: What the battery % displays is in fact a translation of the voltage of the LiIon battery. When you switch off the device the voltage recovers a little bit, thus you get a higher % value when you switch it on the next time .. and which will fall rather rapidly until it stabilizes under the present load of the battery. Also the discharge curve of a LiIon battery is not completely linear.

... and from what I'm reading, trigger gives great battery life. So how do I see what has been eating my battery life up? For instance, I unplugged 40 minutes ago and I am down to 91% already.
The regular option on the phone doesn't do a great job of troubleshooting this issue and just says "Display" and "Cell standby" as the relative battery use culprits. I figure, though, that this must be something I downloaded that is killing the battery. I love the ROM overall, but if this battery issue can't be resolved, I need to find something else quick. I'm a slave to a charge port.
Thanks.

Have you tried conditioned your battery by wiping your battery stats.bin? Why didn't you flash the newest Trigger?
Yeah, you need multiple cycles for battery to be even close to accurate, and you should recalibrate.
Are you using other kernels or themes?

Let your phone die wipe battery stats in recovery mode. charge to 100% then use the battery calibration app from the market and re-calibrate the battery. I always repeat the process. Sometimes when flashing new ROMs your batterystats.bin can get a little funky so I always do this after flashing a ROM and my battery works great.
Definitely check the Kernel and Modem your running if there not the ones that came with Trigger than that could be causing your problem as well.
From what i have got from prior experiences. Using odin to go to stock as if your phone just came out of the box and then flashing removes all the old files. When i did this i went from getting almost 10 hours... now my phone gets 17 normal and if i dont use it as much as a normal day it iwll hit 24 hours no problem.

This post (http://forum.xda-developers.com/showthread.php?t=806022) is saying to wipe battery stats at full charge... So what is it?
And why didn't I flash the newest version? It was when I flashed it.
What was the use in the 40 minutes after charge? I could see that if you had screen brightness high, and lots of wifi surfing or video use. I downloaded an app called 'screen filter' and it lets me lower the brightness lower than stock and I have noticed significant battery length increase since use. The stock dim options are not enough. Its still too bright and a waste of battery.

Both. I wipe mine at 0 and at 100 but once you wipe make sure you fully charge without interuption and vice-versa

same here, and i suggest you do the charging during night when your sleeping, so then there'll be no interruptions, like having to reboot for some odd reason etc. That can disturb the process of recalibration/conditioning.

Pretty much nothing... Maybe looked at Facebook once and replied to a text?
So I drained it, wiped the battery stats, then looked at what it was doing - probably 1 minute after it was totally dead and wiped. The screen said it was at 14% already.
In less than a minute - 14%...

Let it die again and wipe again. Your stats are off from the flash its normal. Just let completely die wipe charge wipe repeat. It will take a couple times normally to get back 100% right

I used to chage my battery overnight with good results but since going to gingerbread it usually drops from 90-100% whne unplugging. was reading up and found out it's saftey feature created by Sammy.
It is still early days, but I thought I'd share this with all Android users on the HD2.
Like almost all members here, I flashed my HD2 to Android, now using a ROM on the SD, which takes up more battery power. Like almost all users, I too got battery draining issues. So I bought an original HTC 2300mAH battery, and.... no difference!
After installing a simple app called Battery Monitor (NOT Battery Monitor Widget), and changing the battery reading to volts within the app, I continued using the phone. The app showed, at the time of installing, 85% and the standard icon showed 43%. I disabled power saver and continued using the phone ignoring all battery warnings. The battery monitor showed 65%, when the standard icon showed 3% late in the night. I kept the phone on all night with syncing on, expecting the phone to switch off, but, in the morning, the standard icon showed 2% and Battery monitor, 58%.
My point being, the standard battery software clearly didn't read the extended battery's charge/discharge levels and probably needs to be recalibrated. Also, could it be that the standard batteries too are not being read correctly? I mean, we all may be thinking that the HD2 is a power hogger, which may not be the case.
I will be trying this experiment on the standard battery as well, and let all know on this.

Hit "Thanks" if you found the post useful.
do the battery calibration. completely charge and keep phone charging, open termimal emulator and type:
$su rm /data/system/batterystats.bin
reboot phone, after completly reboots remove the batterystats.bin again and then unplug phone and allow to die out. recharge and it should start reading correctly... 100% is aprox 4.2+, use battery indicator to read battery levels and info.

Hey!
You do realize, that the difference between the android system battery level and the battery level provided by the app "battery monitor" is due to different minimum voltage levels?
The minimum voltage level where the system would shut down is around 3.600 mV.
The minimum voltage level of "battery monitor" on the other hand is 3.200 mV by presettings. (actually you can set the minimum voltage manually)
As a result, "battery monitor" lets you discharge the battery more which results in a longer time you can keep the device running.
I would be careful though, cause undercharging is very bad vor lithium batteries, meaning a decrease of the battery lifetime.
Take care,
Ric

Hi!
At the time I wrote this, it was discharging and I was keeping an eye on the voltage. You're right, it completely discharged at around 3.66, and I set that as the minimum voltage.

Hi Friends
i have a galaxy s4 GT-I9505 and my issue is battery calibration.
if i use my mobile battery drain quickly and percentage goes to down and when i put it on standby then battery some battery percentage increase. pic shown the graph when battery percentage up
plz help me out my battery status attached with it
Charge to 100% while your phone is on, pull the battery, put it back in, charge again until 100% while its off.
That's all you need to do to calibrate.
Why are we still discussing battery calibration as if its a real thing?
There is no need to calibrate a battery. Its not a thing. This has been thoroughly debunked at the highest levels, including coders from Google.

Buy a new battery. Try a different rom. Do a factory reset to see if that clears any wakelocks.
Those are all options to try. Calibrating the battery is not. You would have just as much luck with a witch doctor putting a curse on battery draining apps.
This is curious. It's been this way for about a day or so. No actual battery life issues that I can tell. No heat or performance issues. Battery calibration?
T-mobile rooted and my only mod is AdAway.
Other than this issue, all is normal.
Thoughts?

Someone else reported something like this in another topic. I can't remember what type of V20 they had. My thought was that the battery was bad.

I'm almost 100% certain that it's a calibration issue. 100% software. There were similar issues in a Samsung 6.0.1 ROM as well. Bad battery would be never reporting as "FULL" to the OS. Fortunately, even if it's a bad battery, thank jebus for replaceable battery!
One of the things I'm trying was to pull the battery, hold the power button down to discharge any capacitors in the charging or power circuits and then replaced the battery. Now it shows 89% and charging as well as "collecting battery info... please wait.". I'll let you know if it breaks 94%. I think the calibration was off after going a full day of constant usage but plugged in (drove 10 hours while using Waze).
Definitely a calibration issue. The above method had the predicted effect. Fully charged at 100% again. Spread the word. FYI, I held the power button for a good 30 seconds with no battery in the phone and obviously unplugged.
Peace!

Well, you see, at first I thought it was a bad battery, but last night, my battery began acting funny. It was at something like 40% and then I did 1 reboot and then battery was at 25%. Then I had to reboot again, and battery was suddenly at 18% and stayed that way for a long time. I decided to try the calibration thing and it may have solved some of my battery issues (I did a few other things too, so not sure exactly what helped). I was always told that battery calibration was no longer necessary. Something about the way that Android reads the voltage of the phone rather than the capacity now... Or something... I forget the technical mumbo jumbo. Anyways, that's one reason I always had been telling people that calibration is just a placebo and that their battery may just be bad. Now I'm not too sure what to think!
