Battery issue

I am using DCD's newest kitchen and when I have my phone plugged in it will show its 100% charged (green LED and all).. Just as soon as I pull it off the charger it will instantly drop down to 99% then 97% then usually end up at around 95% charged within just a few minutes.. It then kinda evens out and I seem to have fairly normal battery life after that. When I put it back on a charger it will go back to charging the battery back up.
Any idea what would cause this?? Is that really just dead area on my battery that dissipates that quick?
I am on Verizon, using dcds newest kitchen, have a suite of SPB products and s2u2 on the phone...
Thanks for any help or ideas..

This sounds about normal. Especially if you are using the battery meter that changes with increments of 1% rather then 10% like the original battery meter was.
SPB products and s2u2 do use alot of battery power, but this is normal.

yep the 1% meter is built into DCDs rom is my understading..
I could understand (not happily) those products using alot of battery power.. its the INSTANT drop in battery life and the evening out that has me puzzled. I just tested it again and its from 100% to 95% in about a minute. Also when I plugged it back onto the charger it almost instantly pops back up to 100%.. (sometimes within a couple mins)
If that top 5% of power is not usable how can I reset whatever so that it does not even count that portion..
Or is it more of a actual battery issue and I need to get a new battery?

it has nothing to do with battery usage. the moguls are just very inaccurate with their battery meter...htc did not do a good job with this. thats kind of the reason it defaults to 10% increments to begin with.

Battery indicator - setcpu - Juice Defender

Wrapping these all up in the same post because they are related.
I have found that the battery indicator is pretty inaccurate and will jump from say 15% straight to 10%. This goes for the stock battery usage meter in settings, display in the top right on the staus bar, battery widgets, and even setcpu. Anyway to make this actually accurate and provide real time indication?
Also I have been playing around with setcpu and Juice Defender and have found that they essentially do the same thing. They both under clock the CPU at certain times except setcpu doesnt disable wifi and other things. I figured it would be bad to run both so I disabled Juice Defender. If I have to pick one, which should I use?

circle battery widget can indicate the exact percentage.

circle battery widget and other apps only estimates the exact percent, the atrix hardware only allows for 10% increments.

This is not what I have found with circle battery and battery monitor by simmo. They show exact percentages on my phone.

Do you also use setcpu? Did you seem to definitely notice a difference using Juice Defender? Or more importantly any features of the phone change? For example every time you shut the screen on and turn it back on, does it have to find wifi again? Or what about when the screen is off, does it shut down data connections completely so that you don't even receive email notifications?

I used Juice Defender on the atrix until recently. It worked well. I had to set to pull data for one minute every 15 minutes (and it wouldn't stop downloading at the end of the minute unless it was finished pulling what it wanted to. Sure I no longer got my email responded to the second I received it, but it made my battery last ~50% longer.
I also used setcpu to underclock when the battery was <20% and when the screen was off. Juice Defender has this feature for other phones, however, didn't seem to support underclocking on the Atrix.

Thanks for the info

they will show 1% increments but these are just estimates as the atrix hardware cannot show 1%. programs like circle battery widget are not accurate even when they are showing 1%. check out the thread below.

I don't think people here realize how circle battery widget (and other like it work). Nearly all battery widgets just read what the system is saying which is obviously going to be in 10%'s on this phone. What circle battery and a few others do is read the actual voltage left in the battery and make an accurate % report which is why it's 100% accurate down the %. It doesn't matter what battery capacity the battery has either because every Li battery has the same full and empty voltage. So yes circle battery widget is 100% accurate.

^Exactly. Even without knowing that, you can just watch the circle battery widget and the reported system percentage. The circle battery widget always changes consistently with the normal system value, so at the very least it's as accurate as any of the meters displaying the 10% increments.

Not sure where you got the idea that circle battery widget was inaccurate. Like I mentioned above, anyone can observe that it is consistent with the system report, so it at least averages out to be fairly accurate for every 10% block.
Another thing to remember, though a small detail, is the fact that the system displays increments of 5% starting at 15%. That doesn't change much, but that means it's not only 10% increments.

im not saying you are wrong here but where did you get the info that it measures voltage? even if it does im not convinced its that easy to
accurately measure capacity. why are all these phone manufactures have problem with having to recalibrate batteries and wiping stats? why not just always measure voltage and always have accurate numbers?
im no expert im just going with what designgears posted in his thread. he is a developer that made lots of roms with very accurate battery monitor that i used for my captivate. he was trying to make one for the atrix but was told that the hardware only supports 10%. if its was as easy as measuring the voltage then why didnt he just do that?
ive used circle battery and battery monitor that both showed 1% increments for a few weeks and noticed that it was not very accurate. its hard to explain but when i was using the phone it would decrease at a steady rate then when i have the screen off for a few mins it would quickly drop 2-3% (within the few mins that i had the screen off) then it would slow down again, this is why i think its an estimate. dont get me wrong its not too bad for an estimate but if you ever used cognition rom or any other roms on other phones with good battery mods you will see what a really accurate battery monitor is, you can set a timer to it...

I've had a Captivate since release back on July 17th (or 18th I forget) so I fully understand who DG is (And I'm not to happy he jumped ship completely on this phone like he did but it's his choice and it is what it is). Ok so even though the hardware on the Atrix isn't capable of reading the battery in single percents only in 10's it still reports the actual mV of the battery. If you open "Spare Parts" app for example and go to "Battery Information" it displays your current mV of your battery. Now almost all modern Lithium Poly batteries are considered "Full" at 4.2 mV (Obviously this can vary slightly even within the same battery for the same phone model due to manufacturing tolerances) and "Empty" at 3 mV (I think it's REALLY dead at around 2.5 mV but the phone has a built in safety feature to prevent this because if it drops to low the battery wont even take a charge). Here's a link Lithium Poly Battery to this data. All the Circle Battery Widget is doing is assuming your battery is at 100% at 4.2 mV and 0% at 3 mV, then if just divides your current mV by 4.2 and turns the decimal into a percent and now you have your display %.
Now the reason it may drop faster like you said is because the phone OS itself reports the battery mV and I doubt it checks it every second. So say the phone OS checks the mV every 5 minutes (Just guessing I have no idea) and it reports RIGHT before you play a game or a few youtube videos then you stop playing (phone still shows the same percent) and put your phone to sleep then wake it 2 minutes later and now you've lost 2% battery "Doing nothing" but really the OS just didn't refresh your battery mV before you turned the screen off.
As far as how I know Circle battery widget does this is basically common sense, obviously it isn't it getting info directly from the system battery percent because it won't read any more accurate than 10's. The only way it could get even a relatively accurate percent is by the method I stated above because obviously most other battery meters are just repeating whatever the system is stating in 10's.
That's basically all I've gathered about how it works, I could be completely wrong and if I am I'd love to hear from someone who actually knows because I love to know how stuff works

can you share your settings for jd and setCPU when you used it? sounds like you had a tweaked out well.

Hello
I am the author of Battery Monitor (SIMMO Publications), if you're getting 1% values then your phone is either returning accurate values through the Android API, or there exists a system charge_counter file that is updated by the operating system. It does not estimate the value.
Motorola devices (Atrix, Droid2, DroidX), for some reason, choose to ignore the 1% values stored in this system file. The file is hidden, and not many people know about it (apparently). But it IS updated, so these 10% only Motorola devices are actually capable of 1% level changes.
I hope that helps.

Battery life sucks after Trigger 2.9.2 flash...

... 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.

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.

WTF my battery is insane... any ideas?

Ok so I can't figure this out. My battery is kind of "retarded" for lack of a better word.
I can charge it up to 100%, reset battery stats (even if I don't the same will happen)... then let it drain. It will drain insanely fast... I mean from 100 to dead in maybe an hour sometimes...
Then I go ahead and plug it into the charger... for just 15 seconds... when I take it off the charger and turn it back on it'll have another 50% battery life, sometimes more sometimes less....
It's almost as if the battery isn't reading correctly and then the phone can't detect how much battery is left so won't let me turn it on unless I plug it in really quick...
Tried another battery and that one does the same thing.... What in gods name could be going on...
and yes.. I searched... before I hear the hit the search 2000x times.

Here is the instructions from the ExROM thread, they worked perfect for me:
Code:
--> For battery life: I think that you have to calibrate your battery.
- Run the device down until it turns itself off.
- Turn it back on and wait for it to turn itself off again.
- Remove the battery for 10 seconds.
- Replace the battery, but leave the device off.
- Charge the device until full and then for another hour.
- Enter recovery and go to advanced -> wipe battery status. Apply it.
- Run the device’s battery down until it turns itself off.
- Turn the device on and charge for at least 8 hours.
- Unplug the device, turn off, then charge for another hour.
- Unplug the device, turn on, wait 2 minutes.
- Turn off again and charge for another hour.
- Restart and use as normal.

I shall try those but who knows...
I've literally been turning the phone on, it dies the minute it hits the lock screen. Plug it in now for just 3 seconds until it says VIBRANT, it will load up shut down.. have down this about 30 times...
I'm lost on how the phone has enough juice to boot and shi*.... it's driving me nuts doing this over and over and over.. oh wait just turned on again and it's at 5%. This is stupid....
lol i will post back after I try these instructions I guess....

You MUST calibrate your battery every time you see a weird behaviour or install a new kernel. You wrote that you tried another battery, so we can exclude a premature death of the battery.

are you able to get into RECOVERY mode and stay there without it rebooting? Or even Download mode?

yo i dont understand.. didnt a google employee go out and make a public statement that batterystats.bin has NOTHING to do with battery calibration, its only used to keep the data from the settings>battery use graph throughout reboots? In the same statement, i think i remember she told aandroid users NOT to let their batteries die and charge em full cause that will damage the batt.

Bad news bro, your battery is bad. If you full discharge/recharge all the time, it will just hasten its death. Deep cycle charging when the battery is that far gone doesn't really have the same effect.
Try coaxing it back to life by recharging it to 100% then hitting the charger again at 75% a few times. This will increase the capacitance of the battery if there is hope of life. If it doesn't improve, its life is almost over.

thanks for the interesting read, i love reading things that the mind thinks as something for a weird reason.. Placebo effect etc.
Putting your battery down to an absolute 0% will do nothing but hurt your battery. This would have worked if we were still in the 80s and 90s, but these are Li-on batteries, they work differently and it actually hurts them.

Ok so I have RESTORED the battery...
Here is what was going on after further looking. I downloaded a battery stat/drain program to see what exactly was going on...
Under a load the battery mV will change drastically, then once it settles down the mV will actually rise making the % rise...
So I completely killed the battery, I mean dead.. Restarted the phone, plug it in for just a second.. I took it to the point that I killed the SOB battery.
I then charged it up, and while charging I would use the battery drain program. the mV would change drastically and I did this every 10%.
So far so good, the phone has been on for 4 hours now and i've only drained 8%... I will see how it continues.
I've also been resetting my battery stats not because I believe it relates the phone to the actual battery % but the % would fluctuate on the phone, and I thought the phone was saying "batterys dead don't turn on" kind of thing...

Ok. Again.
Here is a more in-detail article with a quick google.
http://www.atomicmods.com/Categories/QandA-Batteries.aspx
How long will these batteries last?
Lithium-based batteries have a lifetime of 2-3 years. The clock starts ticking as soon as the battery comes off the manufacturing line. The capacity loss manifests itself in increased internal resistance caused by oxidation. Eventually, the cell resistance will reach a point where the pack can no longer deliver the stored energy; although the battery may still contain ample charge. Increasing internal resistance is common to cobalt-based lithium-ion. The speed by which lithium-ion ages is governed by storage temperature and state-of-charge. Figure 1 illustrates the capacity loss as a function of these two parameters.
Click to expand...
Click to collapse
Although, there has been arguments for years about Li-ion "memory". Li-ions are not afflicted with the "memory" issues of other chemical types. What they are afflicted with is the inability to hold a consistent current under stress/load with age/oxidation (aging effect of the Li-ion batteries). This is where your battery sits. On the precipice of death. You may get another year or two out of it (if you're lucky.. really more like a few months) with a few correct charging cycles, but that is it.
Bringing a Li-ion to near 0 and back does not help the battery, it is 100% a placebo effect with short term gains at best. A common cause of your particular problem...
Lithium-ion batteries are often exposed to unfavorable temperatures, and these include leaving a cell phone in the hot sun or operating a laptop on the power grid. Elevated temperature and allowing the battery to sit at the maximum charge voltage for expended periods of time explains the shorter than expected battery life. Elevated temperature and excessive overcharge also stresses lead and nickel-based batteries. All batteries must have the ability to relax after charged, even when kept on float or trickle charge.

I'm giving random googling as I know it's difficult to believe a random person on the internet. No two type of manufactured batteries are created/engineered the same, but I'm basing my statements of chemical composition and the basic fundamentals of the Li-ion battery tech.

How to check the true current state of the battery.

This is a simple test to see the real efficiency of your battery, since we often blame a kernel, applications, or rom responsible for the low efficiency of the battery.
I remind you that is also useful with regards to warranty replacement of the same, since the battery is integrated into the phone, has a two-year warranty.
In fact, the battery has a limit if after the test result in lower, then it is repaired under warranty.
how to perform the test:
To test, first charge the battery to 100%, unplug the charger and put the phone in airplane mode.
then type in this code: *#*#3424#*#* will appear, the HTC logo, and you have to choose ACCEPT, then select BATTERY TEST and then RUN.
the test will last approximately one hour, at the end of this will give a result that varies from 0 to 100.
if the result is 75% or less, it means that the battery is faulty, if it is higher than 75% means that it is ok!
If you want you can write a post with the result so to get an idea of the status of our batteries.
good test at all.

My battery =>70%, just use 10% for test, from 100% to 90%, is that ok?

i think HTC builds in some kind of chargign scheme where the charger doesnt full charge yr battery

I did it when the battery was only 1 week old and it lost 6% of the battery. will do the same test half yearly

My battery =>70%, just use 10% for test, from 100% to 90%, is that ok?

should, but next time do it with the fully charged state, is the most truthful.

is there any other faster way to check?

For those of us not using stock Roms, what other options are included in this HTC menu? Any chance we could get some screen shots?
