hello mates,
I have rooted my htc desire and installed redux 1.2 ROM(gingerbread) with a ManU kernel...When charging the LED changes to green precisely at 90% (which i dont have a major problem with as it will go all the way to 100% if kept on charge)..also the phone will die at 10-15% of battery...I have read other threads regarding this same problem and am wondering if its a calibration error or is the problem with gingerbread ROMs as someone pointed out...Otherwise the battery is fine...and gives me a decent 1-2 days of use with moderate usage...its jus the problem abt the 15% n going dead which is a lil troublesome as the fone has died on me many a time for that last important msg, call or IM...any help appreciated...cheers..
That's not really a problem. The green LED at 90% is normal for android (try to fix it with battery calibration, helps sometimes) and the shutdown at 10-15% is also normal. Just take the last one how it is, all batteries are different. Some phones shut down at 5%, others at 20%.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
noticed this on ICS dev rom too but also had it on my old G1
wipe cache,battery stats try diffrent kernel

You should try calibrating your battery for the 10-15% dying problem.
And as for the 90% LED changing to green, all AOSP ROMs do that, so no worries there
What worked for me was charging it while the phone is on, when the LED turns green, power it off and charge it again till it turns green.
Repeat this twice and then reboot.

This is to calibrate the battery. Some people find it useful to run a program called BatteryRepair, in my case I noticed a clear improvement on battery performance.
To avoid calibration problems with the battery, remember to unplug your phone when you flash a new rom!

Turning off at 15% of battery with Supernova 2.4 ROM
I am using Supernova Xtreme 2.4.0.0 ROM, and my phone turns off at 15% of battery. My battery is freshly calibrated and this problem did not occured with LeeDroid ROM and with the stock ROM neither. On the Droidzon page I have found some info in FAQ section, which says the following:
Question: Recently I let my battery go completely flat. When I switched my handset back on I was bombarded with forced close messages.
This has been reported once previously, but could not be reproduced under Sibere’s extensive testing under similiar conditions. For the same reason, unfortunately, we dont have a solution too. The OS is supposed to prevent a complete drain, and to shutdown at 15% and then 5%. The shutdown at 5% is supposed to be forced too. If it shutdowns, then this issue shouldnt occur. Data2SD depends on a normal shutdown to prevent data corruption. Once Data corruption has occured due to untidy shutdown, data is not unmounted cleanly, and then the issue can recur on every subsequent boot, which would require a complete reinstall.
So it seems to be normal, connected to the ROM, and NOT connected to my battery (it is calibrated).
My question is (which goes to Droidzone firstly), what should I do, if I want to use this ROM, but I do not want it to turn off at 15% rather I want it to turn off my phone at 2%?

I'm afraid this is not similiar to the issue in the FAQ. Your issue is that phone shutsdown at a level earlier than expected. The Data corruption issue is because the phone did not shutdown at the expected level and went down to as far as zero level of the battery, which resulted therefore in an untidy shutdown with no sync or clean unmount of data2sd partition, and hence ext4 errors. The 15% shutdown level is a normal soft shutdown prompt (which was missing in case of the issue reported by the user). The shutdown at 2% is the normal forced shutdown by OS.
As I said previously, your issue seems to be due to a poorly calibrated or defective battery, and it would help to do a calibration as per guides on XDA. If this fails, have the battery checked. To reiterate, it's not a rom issue and not something like a bug in the rom.
Thanks. So normally the phone with Supernova ROM should turn off at 15%. After that I have to be able to turn it on again, and use it till it drains to 2%, and shuts down finally.
For me it just shuts down at 15% and then when I switch it on and it boots up, the battery level shows 0% and it shuts down immediately.

No, a normal rom would popup a warning at 15%, asking the user to shutdown. If he doesnt, it would continue, and then give additional warnings, and finally do a forced shutdown at 2%. If it shutsdown before that forcibly, it's something peculiar to your hardware.
Ooops, so Supernova ROM should behave exactly the same way as a stock ROM (or any other) does in terms of warnings and shutdows.
I might try to do something with battery calibration. Should I do it before or after flashing Supernova? Or it does not matter? If I flash a new ROM, does it delete battery logs or it stays as it was before flashing?

Correct. For all intents and purposes, Supernova is exactly like a Stock rom. Difference is only in where internal apps are stored.
The so called calibration is just a file at /data, which means it will be wiped when you do a wipe for rom install.
[Update] Problem solved. I flashed UOT battery MOD after first boot (not before). Now it works perfectly.
A flashed the ROM again, did the battery calibration several times, but the phone keeps turning off at 15%. I checked battery voltages at different levels of battery, and I experienced that at 16% it is 3635 mV, then it turns off below 15%. When I turn it on, battery level is 0% and the voltage is 3390 mV, and when it is charged up to 1% it is 3723 mV, which is higher than it was at 16%. What is wrong here? Actually I use UOT kitchen battery MOD, can this confuse the system somehow?
i would like to know if someone have this problem: at 60% the battery fall at 49% (see battery history)No wifi, no data, no bluetooth, and screen off.

Merci! I have already follow-up this way. I'll try again.
I don't have CM7 I have MS2Ginger 2.1 but I have the same problem. My battery drops 2 times: from 54--> 49 and from 25-->19...I had the same problem when I was using MIUIs and cm7 ROMs.
I think that the battery is just dead in those areas :-(
What does it mean "the battery is just dead in those areas" because when I use this rom (umts_jordan_emara-user 2.3.6 4.5.1-134_DFP-139 1318560162 release-keysEPU93_U_00.60.00) no problem.
Hmmm...Well Im goin to try this ROM too then.
I thought my battery cells were dead (smthn similar was on my notebook and when I replaced battery, everything was just fine) but if u say that everything is fine then I will try out that one.
Tnx.
Have u tried that CM7 ROM with different battery maybe?

No. I have my defy+ since November so the battery is new. I have only try ms2 ginger2.1 with the same problem. Only with motorola oem rom no problem like this.
I have erased files in /data/battd/ and wipe stats battery (i don't now if is the same things). I will come back after this test.
Try recalibrating with the method in this link: http://forum.xda-developers.com/showpost.php?p=11803458
I've used this many times without issues and it always helps with my battery life. With the Defy you have to follow the method that requires reinserting the battery before the lockscreen pulls up.
So after doing steps 1-5 then 6 then do we have to do step 7?
I didn understand you when is the right time to put back battery? Like in 8b?
After this crazy method, u don't have battery drops?
Skip step 7 and continue following from 8b. Hold your phone in your hand while it's booting without the battery and you should feel the haptic feedback (minor vibration) before the phone finishes booting to the lock screen. As soon as you feel the haptic feedback put the battery back in. Leave on the charger until it reaches 100% and then another 20 minutes after that.

ok i will try this method. Im crazy with this problem. When i use cm7 the battery say 49% and with 2.3.6_4.5.2-109 DHT25_themed MultiLanguage, i have 39%, even with battery monitor widget.

can i use "battery callibration" for step 2 :
"2. Delete /data/system/batterystats.bin" ?
Ok. i confirm this steps works for defy+. Before unplug i have 4198mv and after 4164mv. Now, wait and see.
I have Defy with red lens and installed 2.3.6_4.5.2-109 DHT25_themed MultiLanguage ROM yesterday and fully charge it to 100% and one hour over that...Battery was on 4164mV...When unplugged it 99% and 4164mV.
But then i had like this:
54% - 3769mV
50% - 3757mV
49% - 3773mV
48% - 3760mV
...
...
27% - 3686mV
20% - 3692mV
19% - 3670mV
18% - 3679mV
Funny thing is that when gaps happened lower % has more mV than upper % ...
I will try this "new weird" method of calibration tomorrow when I fully charge my phone again tonight. Really hope this will fix my battery.
my defy on Cm 7.1 stable and i get 4160mV on 100% charged and still plugged in to electricity.
but after i unplug the charger, it downs to 99% - 4125mV..
i think i'll try that 'hard' calibration method

Same problem: 69% ( 3782mv) and after 49% (3814mv!) and now at 40% i see 3782mv idem with 69%
What is the problem???
And when u are on your stock ROM those things never happen?

No.
i have a noob question for all: is it possible that the last 20% charge (80 -100) with a 1650 defy battery and rom not based on stock rom, be 'virtual', because i have 20% lost (69%-49%)? (sorry for my english)
Now i decide to put a new Battd file from the stock rom and i try again this hard calibration: charg at 100%. after step 8 i see 5% and 4317mv.
(100% full for defy+ battery is approximately 4320mV)
okay so for the past weeks, i have been running the latest cyanogen rom nightly and i read about the script by puremotive that improves you battery life so i flashed it, everything was working wonderfully, noticed increased battery life but yesterday when i woke up my phone was off some how, so i turned it on and before i could even open an application it turns off. i mean like just turns off no bootloops whatsoever. When it turns off, if i have like full battery charge its drops down to 15%
so i was wondering is it my battery thats the problem or the phone?
and yes ive tried wiping everything and even flashed a different rom.

Ehhh it seems like its the battery, cause my phone only works when plugged into a charger
My phone was all fine, till i flashed Arco's CM10, then my phone started randomly switching off. When started, it showed 0% battery, which was weird as it was always properly charged.
Then i restored my CM9 backup, to check if it was a ROM bug, but I got the same error again.
Attached screenshot for battery stats. Battery problem or Software bug ? Anyone with same bug ?
After flashing the ROM, did you wipe battery stats? If not, that will probably be the cause of the weird readings......
Basically, over time, your phone would have calibrated the battery usage to your previous ROM....when you installed your new ROM (that has different battery usage patterns) your phone is still trying to apply the stats from the old ROM which is what is causing the problems.....wipe your battery stats then complete 3 or 4 full charge - full discharge cycles, and things *should* settle down....

Try the battery calibrator on the playstore.
If it still persist then the problem is in your battery.. suggest you change the battery with the new one
Pressing "Thanks" button will be much appreciated if user's posts useful for you
Or you can try this:
Clear battery stats via CWM. Turn off your phone, and charge it. Wait until the charge indicator shows up on screen. Then turn on your phone and leave it until it's full.
Sometimes when I get batt weird reading, that trick works for me.
In some occasion I found that offline charging and online charging shows different battery level.
when should i plug the cable if use ur trick?

Clear the battery stats first via cwm then turn off your phone after that you can plug in your charger.

Just like reddvilzz said above. After charge indicator shows up on screen, turn on your phone (but do not unplug the charge) and leave it until it's full.
Hi
I have a strange problem with my DHD.
Problem: not charging when phone is on, nothing happened, diode not lighting.
But when phone is off it is possible to charge the battery.
Problem is occurred on 2 batteries (unfortunately not original - one is Andida and another one is compatible from other HTC device) and on different ROMs.
Some time ago everything works perfect until something happened with battery status - it started showing wrong stats and the charging problem was appear.
Is there any solution?
And sorry for my bad English
If You install different ROMs - wipe battery stats.
