Strange battery issues

I'm running a Sprint Mogul using no2chem's nueROM 2.2 Preview 7 (8's touchscreen issues made me downgrade), and having some very peculiar battery problems I'm hoping someone has advice about.
A few weeks ago I woke up, pulled my phone from the charger, and watched the battery instantly drop from 100% to around 83%. Over the next 15 minutes it dropped to the mid-70s before leveling out and discharging at a more normal rate. This occurred the next day and so on. Now this was with Seidio's 3200mAh extended battery. I then switched to my (sigh) OEM battery and didn't have the same problem, so assumed it was Seidio's battery, filled out an RMA, and sent it off to be repaired.
Now a couple of days ago the OEM battery started doing the same thing. I'd pull it off the charge and it would have somewhere in the range of 60% battery remaining. I'd have to plug it into my car charger or USB cable on my notebook to charge it up the rest of the way (albeit very slowly).
This morning I decided to watch the process from before I even unplugged it. First I noticed the orange light was on after a full night's charge. If memory serves me, the light's supposed to go out when it's at 100% (I may be mistaken). Meanwhile the battery meter was at 60%. I unplugged it and it remained there. I plugged it back in and watched no2chem's charge meter show the power connection, and I went ahead and left it plugged in for a little while before checking it again. It was now at 63%.
So what I'm finding is that at some point during the night my phone stops accepting a charge, despite the charge light remaining on.
I'm going to experiment with two things to further troubleshoot: tonight I'm swapping chargers with my wife's. I'm pretty sure the phone controls whether or not it's continuing to charge the battery, but I'm going to rule this out the only way I can. Then if that doesn't improve it I'm going to flash back to a Sprint official ROM (sigh) and see if maybe no2chem's power applet or power management settings are somehow causing this oddity.
Does anyone have any extra experiences with problems like this that might give me an idea of what else to try? Otherwise my thinking is if those two steps yield no improvements, then it's the phone's physical battery management hardware that's faulty and I'm going to have to use my insurance to replace the phone. I'd like to exhaust all the other resources before I spend the $50 on the deductible, though.
Thanks!

sometimes mine overheats while charging, at that point the LED flashes orange until it cools down enough to resume charging, this might be happening to your in the middle of the night

I thought I heard purple meant overheating. Either way, it's not clearly describing it. Also this has never happened before, so if it's happening every single night now, I've definitely got a problem.
Anyway, just plugged it in with my wife's charger. Let's see how it turns out in the morning.

Sure sounds like a bad charger.

Now confirmed. Just pulled it off my wife's charger after a full night, at 100%. Five minutes later, 99%. Much better. I wonder what would cause the charger to stop charging halfway through the night, but keep the charge light on. Well, at least the mystery's been solved.

I am sort of having the same issue. A couple of weeks ago I decided to upgrade from the standard Verizon ROM for my xv6800 to DCD's 3.2.2 ROM. The upgrade went perfectly. I always plug in my phone every night before I go to bed. The light turns orange while it is charging and then it is green when I wake up. The phone always showed 100%. Now with the updated ROM, I do the same, plug in before I go to bed, the light turns orange, and it is green when I wake up. But, when I look at the battery level when I unplug it, it is usually at about 94%. The battery level also seems to go down quicker than before, but I figured that had to do with the GPS radio and WM6.1. Why do you think the battery would no longer show 100% when I unplug it? Seems very weird that right after I upgrade the ROM my battery would start failing.

DCD roms included new code to show 1% changes. The original code showed 10% changes only. Originally, you likely saw 100%, 90%, 80% etc. Now you see 95%, 94%, 93%, etc. It seldom goes to a perfect 100% and it LOOKS like it is discharging faster. In reality it is simply showing more detail.

Yes, I noticed the 1% increments, I figured it was Windows Mobile 6.1 compared to 6.0. I think the old method was reporting in 5% blocks.
So, your battery never shows 100%? Very weird. So, my battery is probably fine and it is probably behaving just like it always has?
Thanks for the information.

Wow...just one calibration effort, the whole thing changed.

So I followed the calibration method outlined by Sprint/HTC and wow oh wow, completely night and day.
Before the calibration, I let the phone charged over night and unplugged it to go to work. Within first 2 minutes, it dropped about 4% which is crazy. The rest of the day is gradually fading and I get about 16 or so hours with very light usage.
Fast forward! Did the calibration by plug unplug, plug unplug for like 15 times while watching football. After the calibration, I pulled the plug and it's been almost 3 hours with only 1% gone. This is just crazy if you ask me by just a simple technique.
I'll let it go unplug to see how far I can get. Oh on top of this, I use setCPU to scale and JuiceDefender as well. Same settings before calibration.

If I'm not mistaken its this:
To also help with Battery Life you can do these steps exactly:
1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour
Please tell me if this is not what you were talking about.

I tried both methods and the only way it worked was if I did it every time I charged the phone.

Link to method? I want to try it out.

Crap, I forgot where I saw it but I remembered it for the most part.
Charge your phone fully to 100%.
Once done, turn on the phone, the light should be green. Unplug it and wait until green led goes off. Now plug the phone back in and wait until green led goes ON (it will almost be immediate). Now turn the phone off and unplug the from charger, wait for led to go off, now plug the charge back and wait for the led to go ON (Note: if you are using CM6, I think the screen will turn on automatically when phone is plugged in. If so turn the phone/screen off). Now unplug and repeat this step for about 10-15 times.
After this, unplug your phone and let it sit and you'll notice the difference.

The method above is not what op was talking about. HTC method is above somewhere.
Charge with phone on for 8 hrs.
After charge with phone off for 1 hr
Then charge again with phone for 1hr on (not sure on this step).
That's the HTC method they claim worked a whole lot for them....
http://forum.xda-developers.com/showthread.php?t=712990
That's the way to calibrate it...

The post above yours IS from the OP. That said, he may not have been talking about the official HTC method. Either way, I have tried every method on the forum and all work... for a couple of days. I havent seem one yet that will keep the battery calibrated for a substantial amount of time.

the reason the unplug plug in unplug plug in method doesnt work all the time is basically you are over charging your battery. I dont recommend it personally. I would follow the HTC method. takes longer but less dmg to the life of your battery. I ussually do it about once a month and it holds pretty true.

My solution is to charge the batteries in an external charger. Every morning I out in a afresh battery and its great. Its only the phone that can lose the first 10%.
I don't charge the phone directly anymore.
Sent from HTC Evo.

I just did the "official" HTC method. Well see how it goes....

Or, you could see that the phone has a serious bug and does not trickle charge after it hits 100% and does not start recharging until the phone drops below 90%. So, when you take it off the charger in the morning it will have somewhere between a 90% an 100% charge. This is why, when you unplug it, your phone quickly drops to around 90% and the behaves normally.
You can easily fix this by unplugging your phone for several minutes (5-10) and then plugging it back in to get it back to full charge. You will notice that your battery % doesn't drop nearly as fast and it lasts several hours longer. Or, as was said above, you can charge your battery in an external charger (these don't have HTC's bug).
I get 6-7 hours of solid use (screen on, surfing the web, listening to music, watching videos, texting, emailing, and and making calls). Oh, and I use 4G often and still get 4-5 hours.
Anyhow, that's much simpler than all those steps IMO.

phone charging problems

hey xda friends,
i have a small problem with my batterie /charger.
it is charging very slowly i am running cm7 so i plug it in very often yesterday at 6 pm it was almost flat so i plugged it in but keep on chatting and surfing/reading so battery wasn't gaining and it kept reading 5% (same as when i plugged it in) i thought well it's just usb so i use a lot of power and it keeps it's level
but when i got to bed (1am ) it let my wallcharger do the task
today when i got up(6am) i looked at my phone and it only read 80% (before i deplugged it) perhaps somebody knows the problem (battery /phone) i have just original parts (charger and battery) i am running cm7 for a while (yesterday i just switched to 2.3.3) never had this problem before....
i tried
power off
power on
pull battery
wipe battery stats
....
thank you for your help

Could it be you have something draining the battery heavily?
try a full wipe then reflash

no new installed apps and unplugged it drains normally

Pull the battery, and with the battery out hold the power button for a good 30 sec, on most hardware these days this is how you usually hard reset the power management unit. Try it and lemme know how it goes.
i dunno if this will work for SGS but i guess you have nothing to lose.

thank you for your help unfortunatly it didn't work ordered a new batterie will report

push it real good nanana

if the battery drains normally.. .. then perhaps it's the charger itself (???)

I was seeing something like this but not as drastic. Tried a different wall plug and things were better.

i tried it at two spots but with same results on both outlets my desire hd charges nornally
i think it could be the battery
i get a new one on monday i will report

I have a similar problem. My phone also never charge to 100 percent. It reaches to max 85-90 percent and if i continue to charge it starts discharging. If i let it to charge till morning, when i disconnect the charger i read 65-70 percent. I have another battery but not original, it behaves more weird. Dont know if the battery is problem.

I have tested with the wallcharger. It charges to 100 %. And the phone battery drainage is normal. Like 2 days.
Remaining possibilities.
1) Firmware problem. Reflashed the phone with the new firmware. I will see if it changes anything. Not likely though.
2) Hardware problem. The phone's charging usb part damaged and there is some kind of disconnection.
3)May be bootloader got damaged??? Even if the phone closed, it doesn't charge to full capacity.
Edit: The problem seems to be the second one. While flashing with odin it failed many many times. I was just scared that the phone was brick.
Then i realised that the connection with odin is not stable. I press with my finger the the usb charging cable to left and right and I have seen that
the connection comes and goes. After that i have succeeded to flash the phone while pressing to the mini-usb part with my finger. it seems that
that while charging also the connection is not stable so it never fully charges.

[Q] Samsung Tab 7.7 - Battery Life & Warnings

Hi there, I purchased my 7.7 Tab 3 weeks ago. Loved it as expected. I've got few concerns about the battery though. Hope someone can share solutions / experiences with me.
The battery life isn't so impressive as I heard about from reviews and all. It lasts hardly 48 hours after a full charging with no real use for more than 30 minutesx2 times within less than 48 hours. However, it was connected to WiFi all the time and was syncing as well (but on standby all the time). Now another bugging problem is that when I plug the charger after the battery having completely drained and the device is turned off by itself (before completing 48 hours), the screen shows a warning logo first instead of the charging icon. The warning logo has warning sign and the icon of a drained battery with a red color at the bottom of it. I do not know what does that mean. I just know that when that appears, the device is not charging at all. I have unplugged and plugged it back 3 times to get it charging again. So far, it happened two times and I am sure it will happen again but I just want to know whether this is the sign of an unhealthy battery or any other parts of the device? This happened to anyone else? Your feedback is welcome and well appreciated.

Install SetCPU. :good:

sometimes... the cable is the culprit... a damage cable will gave the same error... btw.. it is not advisable to really drain the battery dry before charge it... but that just my opinion... just try to check the cable... and if there is anyone around you that having the same cable... test to charge your device with their charger...

First of all, you may not want to have left the battery completely drained, as this might damage the battery. Secondly, since your battery is completely drained, some undercurrent protection mechanisms must be activated, and there should have enough input current before the battery could be charged again. The data cable should not have enough current to charge up the battery at this state, it is lucky for you that you got it charging again after three trials.
If you drained up the battery again, it's recommended to charge it up with the AC charger.

[Q] Is my phone dead?

I recently was on my phone texting and I set it down for about 2 hours and came back to it and it was off. So I thought, well thats strange and so I tried to turn it back on and nothing happened. So I took battery out and put it back in and it came on for 1 second then off, every time i took battery out and repeated. So I held power down for about a min w out battery, nothing...tried recovery, still turned off. Tried different battery, nothing. So Im sorta confused idk what is causing this...is it like dead? Can I fix it?

Interested to hear of anyone else has had this problem. 4 batteries and all showing over 90% in CWM, which does stay up when I bring it up. Have you got into your recovery and does it start on okay for that @Rocklee99

I cant get into recovery or download mode, itll shut down before it reaches their screens

I ended up getting rid of my China batteries. The external charger (purchased off of eBay with 3 batteries) would show the battery fully charged, even in reality, I'm guessing it was only partially charged. After so many times of "partially" charging and then discharging in the phone, I'm betting that the battery was more like 20% but showing fully charged. Confusing but these batteries do have a memory and if the wall charger is only charging to 20% capacity and shutting down the charge circuit, thinking is at 100%, after a few times of that, that's all these batteries will charge up to. Bad batteries, because new batteries were just fine with a new wall charger.
