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.

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.
-Valynor
can anyone make a 1% battery driver for our tg01?
What do you mean with 1%? That the battery status about 88% or 78%?
yes meaning the battery displaying 1% increments on discharge
The problem with this I think is in the hardware... and batteries in general. To monitor battery charge, you look at voltage level, so the accuracy is based on how much the voltage fluctuates and the sensitivity of our internal volt meter. I think the best you can hope for is 5% increments accurately...
I would also like more accuracy in my battery level indicator.
Someone please correct me if I'm wrong.
even 5% increment is still better then 10%

Exactly. I never had 1% or even 5% increment battery level display on any wm phone i owned. I come to think maybe it's an HTC advantage only
thats not right. on mda vario is 1% status and i thinking it's on all mda versions. greats alcatras

it also was fixed on the SE X1(htc kovsky) by a fix in roms ... stock roms only showed 10% battery levels , patch applied , it was 1% , OP knows whats hes talking about , u should contact the guys who made patches like that for that and other phones (cuz its not the only one that got that patch) to know where to start
Hey everyone,
I'm kind of a noob when it comes to all things XDA (but I'm learning.) Anyways, I was wondering what kind of battery life you all get from the different ROMs you've flashed.
So far I've only flashed Nero, Bionix, and Flagship. I had pretty good battery life from Nero, but I was wondering what kind of battery life that you've experienced with other ROMs like Axura and Trigger (because with Bionix and Flagship, my battery life has been fugazi.)
Thanks in advance, y'all.
Sorry if this topic comes up often.
With axura my battery lasts 16 hours with possibly 600+ texts and youtube alot music about 1 hour a few phone calls alot of web.
I only need it to last 12 hours because I charge overnight so I'm good.
I reconditioned too btw
Does reconditioning actually improve battery life or does it simply make the battery indicator more accurate?
It makes it more accurate. Which in terms helps battery because it reads it perfect so ull last longer
Axura is widely considered to have the best battery life. After flashing a new rom you should let your phone charge to 100% and then wipe battery stats in CWM recovery. It can take several days for reading to be taken from the battery so your battery life will usually improve over time.
Hey, I just wanted to thank you all for your input. I decided to go with the latest version of Axura, and so far I've been loving it. I'm not even a day in and I've noticed a difference.
Thanks once again.
+1 On Axura best battery life........

first thing to do is
Charge Until 100%
choose rom
Run The Phone All Day, Let It Die
Charge Until 100%
Reboot Into Recovery
Select Reinstall Packages (Do it again if needed)
Select Advanced
Select Wipe Battery Stats

Neither. "Conditioning" skews the discharge curve from which the battery indicator indexes it percentages. As a result, the battery appears to discharge at slower rate ("better battery life") over the first two-thirds or so of the discharge cycle and then craters like a lead balloon at the end of the discharge cycle. (You really need to have a battery indicator that shows discharge in 1% increments, such as "blue segmented battery mod" to see this.)
To understand this requires a light understanding of the so-called "battery stat tables." There is an entry in the battery stat tables for each percentage of remaining battery charge, in increments of 1%. So, the table contains entries 100%, 99%,... down to 1%. Associated with each percent of remaining charge entry in the table is a battery terminal voltage and a timestamp. Unfortunately, the smart phone cannot measure actual remaining battery charge. All the system knows is a series of battery terminal voltage measurement taken at even periodic intervals. The algorithm builds the battery stat table to relate each measured voltage to a corresponding “percentage of remaining charge” entry in the table. In normal operation, the system accumulates these measurements over several charge/discharge cycles and analyzes the rates of changes of voltages to refine the discharge curve. After several charge/discharge cycles the percentages, which are displayed on the screen as a battery indicator, become more refined and accurate.
At some point someone apparently thought that it would be a good idea to attempt to manipulate the process of building the battery stat tables. This resulted in the so-called "conditioning procedure." The conditioning procedure consists of fully charging the battery, then deleting the battery stats, and then draining the battery quickly and completely using heavy loads, perhaps in 1 to 2 hours.
What this accomplishes is that the battery stat mechanism builds a new, steep discharge curve based upon the rapid discharge operation. This crude, initial discharge curve has "learned" that the battery should discharge quickly, because it did so during its "training” discharge. More specifically, each "percentage discharge" entry for the first 1/2 to 2/3 of the discharge curve (corresponding to the first 50-75 table entries) will be associated with an abnormally lower voltage (due to the faster rate of decrease in voltage during the "training" discharge cycle) than would be the case if the table had been built normally, over time.
Now, let us think about what happens during the subsequent discharge cycle. We charge the battery to full. Now we begin to use the phone normally, discharging the unit over a period of 12-18 hours, for example. Now the phone experiences a slower rate of change of battery voltage over time, because the load is much lower than that of the forced "training" discharge. Now the algorithm measures a voltage and then attempts to map that voltage to a corresponding percentage discharge table entry. The result is that the battery indicator on the phone shows a very low rate of discharge over many hours. This leads people to erroneously conclude that the "battery conditioning" procedure results in improved battery life. However, this is merely an illusion. The battery indicator is, at this point, simply displaying an incorrect number for the remaining battery life. As a consequence, the battery indicator must "catch up with reality" later in the discharge cycle. This is manifested toward the end of the discharge cycle as the battery indicator drops precipitously from perhaps 35% to zero in a very small amount of time. In any case, fortunately, the weirdness done by "battery conditioning" goes away within a few days as the battery stat algorithm tunes the discharge curve each discharge cycle to bring it ever further in line with the actual average usage of the phone owner. It is a myth that the battery stats become inaccurate over time. To the contrary, the algorithm continuously tunes the tables based upon usage patterns so that the battery indicator becomes more and more accurate.
I do not know where this practice originated, but I do have a cynical hypothesis. The ROM cookers typically mix-and-match code elements from different software releases and otherwise change up the timing, sequencing, etc. of various processes. Doing so may have battery life consequences, because the resulting mish-mash of components may hinder or prevent sleep mode operation, cause processes to run for more time than they should, etc. You can see how "battery conditioning" could mask an acute battery performance problem during the first few hours after a person has flashed a ROM and is watching performance characteristics especially closely. ‘Nuf said on this subject.

600 texts in 16 hours is nearly 38 texts an hour, 4,200 texts a week, 18,000 texts every month. WTFBBQ?
My phone is 1h30m out of the charges and at 78% battery level, out of those 68% is "phone idle". What is exactly "phone idle" and why it eats so much battery where name suggests on it's own that it shall not be using any battery since it's "idle"

Do you have a feeling this started happening after "battery fix"? I feel like it started happening since I install fix yesterday.
I had the same problem, both before and after the battery fix. I cant get my atrix to last 12 hours with light use before its crying to be charged. Just installed the battery fix and Ninja rom last night; ill give that a try and see how it goes.
Man guys, I'm just rooted, and running the latest stock rom, and I'm amazed at how awesome the battery life is. I can go for almost a day and a half. I do most of my rss feed reading on my phone, and I tend to go for hour long jogs with it strapped to my arm running gps.
Maybe my usage model has something to do with it. When I'm not running, I'm either at home or at work, where I connect to wifi. That might have something to do with my stellar battery performance.
i have the same problem it started yesterday well noticed it yesterday
i went with the new recovery and after a bad install of ninja
installed the new cherryblur I had a problem with the new recovery wipeing user data and had to reinstall after a wipe with fastboot. dont know what the problem is.

after a week testing with everything i can tell you that the guilty was the Kernel.
Flash again the rom that you have been using but do not install that kernel.

The less you are physically using your phone, the higher the percentage of usage Phone Idle will have. Typically, for a normal user Phone Idle will ALWAYS be the highest usage.

this is true. if your not using anything else to drain your battery something will always show up on the list. say you lost 20% of battery in 4 hrs. you have had it sleeping the whole time. well that list looks at what applications have been running so it builds a list on what took out the 20% so if you didnt do anything phone idle would have taken say 78% of the 20% of battery you lost. it doesnt mean its draining your battery more then normal. it means it was the only thing to drain the battery at all. followed by display, android system etc....
International user here with 2.3.4 ORANGEFR. After flashing edgan's kernel my battery issues are pretty much gone. I undervolted as much as I could. At 70% battery right now with 8 hours of moderate use.

That's fine but the problem (see original post) that despite low usage I do have big battery drain and in this case "idle" is in fact appears to be eating 2/3 of it.
I'm in the orange already after little use today and i've only been unplugged for 6hours. I just flashed GB on friday.
Normally I would suggest installing the app Spare Parts to monitor which apps run the heaviest while the phone is supposed to be sleeping...however, on the Gingerbread ROMs, Spare Parts can't show you those stats anymore...very unfortunate.
but spare parts+ can

you never post what android version you are using, im assuming HKTW on ATT atrix? i had the same problem with that build, its full of problems. dont bother installing apps to try to figure out what is draining your battery, its the build itself it is known to have battery issues. theres def a problem if the phone is using 22% on just 1.5h of idle. there's no fix for it. install either ken's gingerbread rom or one of the other roms based on ATT 2.3.4. theres no battery issues with those

Well, no REAL battery issues. The meter still jumps around wildly unless you have the fix installed if you are using the 1% mod. So you can reboot and suddenly have 20-40% more battery than before.

Have you done the battery fix for the GB ROMs? Without it, the drain is reported as being more than it really is.
Have you set up a more conservative profile under the battery management (or wherever the hell it is)?? With light usage, change your settings there to be less performance based, since you apparently don't need it.
And as previously stated...SOMETHING will use your battery. That will either be idle, or Angry Birds. If you aren't using apps, the browser, etc...then idle consumes battery. Use your phone more...or adjust your profile settings to be much more conservative (including turning data off after a shorter time period).

this is a very minor problem that doesnt effect battery life as in it doesnt shorten battery life. it jumps up after reboot but if you use it for a while it will jump back down on its own. there is also a fix that works so its not an issue anymore.
I'm using Kenneth ROM with default kernel. Idle is still top consumer ( more then screen for example). I did not do battery calibration but will do now but I don't think this will fix the issue.

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.
