That's normal (with a lot of ROMs). It doesn't mean it's stopped charging, it should still charge to 100% it's just that 90% is the trigger. Nope, no idea why but rest assured there's nothing wrong.
Batteries don't last forever, they lose charge over time.
To calibrate charge up to max then go into CWM and delete battery info or delete the proper file and that's it.
If you want to make sure the calibration is done correctly then let the battery discharge fully and charge up to max again without a break.
Anyway that's what I have always done and works great for me.
I've never relied on the percentage of battery. I just used the Current Widget and stop charging when it shows 0mA. From my observation, that usually take about 1.5 hour after the led first change color.

The more often recommended method is (via HTC & copied from sticky)
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
Now you can boot into recovery and wipe the stats.
I only suggest this as you have been woping the battery stats a lot and want to make sure all is ok. Although it is also good the first time you get the DHD.
I've done all the steps that everyone has mentioned I was just wondering about the led light going green at 90%

In case there's confusion, I wasn't offering advice to fix it, it's normal behaviour in this case, my advice was just to correct any possible bugs from all the battery resets you have done.

Hey there,
I tried to calibrate my battery the last few days...
There where so different descriptions on how to do it right.
But well at some point they all said to charge the phone turned of ( well it automaticaly jumps into recovery, right?).
And it was said charge it till the led goes green.
But I think it never happens in my case.
In one case I fully chagred my phone powered on and then turned it off, plugged it in again. The red/orange led staied there even after 3 hours...
The other day I fully discharged the phone and wanted to charge it in recovery mode. So I plugged it in, the red/orange led began to flash, recovery booted and I went to bed. About 10 hours late I woke and the led was still flashing as before.
I had no patience and turned it on. With the system running it tells me, that its at 100%.
Turning it off again unplug and replug it will show the red/orange led again but not flashing.
Its a european desire z (germany)
On Virtuous 0.9
With clockwork 2.something
Any ideas? Should I have been even more patient to see the green light in recovery? How long could it take?
Thanks,

It seems the question of how to charge the battery pops up at least once a week now, with the same misconceptions. There is no such thing as calibrating the battery. All you are doing is calibrating the battery meter (just a volt meter) on the phone. Li ion batteries cannot (and should not) be calibrated or conditioned. The best way to calibrate the meter is to charge the phone to 100%, drain to about 20%, repeat a couple times. You should not discharge the battery below 20%. I cover it a little more in depth on the following post:
http://forum.xda-developers.com/showpost.php?p=11026655&postcount=7
I don't see any advantage to charging the phone while its off (except that it will charge faster, of course). I always charge mine while its on (with screen off).
I don't know why your green light is not coming on. Mine comes on after the phone has been charging for about 2 hours or less. But I am on the stock ROM, so its possibly something to do with the ROM, so you might have some better response by searching or asking in the Virtuous thread.
Yeah I know that you just calibrate the voltage meter but its just easier to say battery calibration.
Well maye the misconceptions occur because there are plenty of different answers spread and its easy to become confused. I just avereged over these methods and the consensus was to change fully while turned off.
The only way I could think of loading in recovery is better, is that the software prevents loading when it thinks battery is full (but in fact it is not), but I relly dont know.
And you say even after deleting battery stats there is no need for discharging till shutdown (to show the limits or anything)? To reset on full battery is enought?

I want to calibrate battery and delete old stats.
Thanks & Greets
Well, your problem first if that you said you had recovery 2.x and that if you turned it off it automatically jumps to recovery.. you seem to have the first recovery that the power off feature wasnt quite working well.. upgrade to a 3.x then like the above user said but drain the battery until it reaches %15.. thats when the Connect To A Charger popup shows up.. and charge to 100% and do couple cycles of these..

I have tried to calibrate and wipe batt stats.
What can i possibly do?
Should a calibration have fixed this or not?
Charge phone 100%....then complete wipe; dalvik, battery, etc....reflash ROM...then another battery wipe and a reboot...should do the trick

It does not matter. When i turn it off and put in the charger it goes to green straight away!
Once you have taken it to 100% take it off the charger use it for 5 mins turn it off then put back on charge while phone is off. Or just check out the link yourself

It does not mentioning using it for 5 mins?
Also i already mentioned that I HAD calibrated the battery.
Does anyone know how one can test and see if the battery has been calibrated succesfullt?
Using AOSP Gingerbread ROM? Many users reported their phone shutting down at 10+%.
I'm still on froyo an phone shuts down at 1-2%.
Yes exactly! Using Oxygen 2.0.3
Actually I haven't found posts about other users with shutoff probs around 10%!
---- edit
But actually i also had the problem before rooting and changing rom on stock desire 2.2.
But there it turned off at around 7-8%
I actually came across a lot of posts/threads with this same issue.
Anyways, you should try the following:
1. drain you battery until the phone turns off.
2. switch on phone (it should now say 0%) and drain it, till it shuts down again.
3. charge it to full while swithced off (then take out charger).
4. turn on, let it boot fully and after 5 mins put on charger till it is fully charged.
5. reboot and and in the custom recovery wipe battery stats.
Also this method is depending on the kernel.
TBH, I don't know which isthe best kernel for Oxygen, but stock should do it.
The original version:
This has been taken from the thread on XDA by vidler.
The following steps should significantly extend the battery life on your phone.
Please connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged.
Disconnect the phone from the charger, and power it off.
Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green.
Disconnect the phone from the charger and power it on. Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green.
Disconnect the phone, power it on (OPTIONAL: Enter Recovery at this point and Wipe Battery Stats (from Advanced menu), and use it. You need to use this sequence only once.

I've had the same problem on stock unrooted 2.2. Did a full wipe, root, S-OFF and installed InsertCoinHD yesterday - same issue, hibernation at around 12%-13% battery left.
Everytime my phone reaches 10%, the phone will shut down itself and it won't turn on again.
i have tried bump charging and calibrating the battery but still without success... anyone got any soulutions other then buying a new battery?
thanks.
Try this: fully charge the phone then let the battery drain completely, until the phone shuts down. Plug the phone into the wall charger, let it charge for a minute or so then turn the phone on while still plugged into the charger and let it charge completely. After a full (100%) charge, the battery indicator should be precise.
I've noticed that if i restart the phone of plug it in after charging, the battery indicator will show an extra 10%, so that's the main reason for the shutdown at or a little below 10%.
This operation should be repeated once a month, just to keep the battery and the battery stats fresh.
Don't wipe battery stats and don't try any other calibration tweaks. They might damage the battery. There are some people here complaining about that.
If the phone still shuts down at 10% after the above-indicated trick, then your battery might be old and in need of replacing, but i wouldn't replace it just because of a 10% indicator error if it can still hold a proper charge.
I have the same problem. I also calibrated my batterie and everything but it still turns off at ~10%.
But since I know that, it's not really a problem
Its always turned off at ~15% for me. I accepted that this was normal. I've seen a lot of posts around but no one seems to of found a proper solution. I actually doubt that there is a proper solution to this.
Punched in..
snq's kernel? I take it is normal with it as none of the GB sense rom managed to come even near the 1-2%. A bug with the kernel probably.
Flashed Oxygen last week - bam, phone turns off at 1%. No calibration was needed even .
Every time this happens to me I charge it 100% then I reset battery stats. Then let it discharge threw normal use then give it a proper charge, plugged into wall charger, not PC.....! And once its 100% ignore green light check it says 100% on the top bar then I unplug. Its normally always sorted then. But I have had to repeat twice in the past.
I also agree about kernal, often after updates it goes bonkers, and I'm on miui, lots of updates

Mine also used to turn off at ~14%. After using a battery calibrator, i could push it down to 7%. However, on the other "side" of the scale, it goes down qute quickly from 100% to ~92%. All this on GV2.8, and the unofficial ManU kernel 2.1.1.

Just wipe battery stats in recovery after full discharge if you changed ROM, and then let it charge to 100%.
Used the battery calibrator app (for nexus one) with detailed instructions. Now batt lifeis awesome, turns off at 3%.

Did the thread move or die, or is the link just wrong?
Lately my phone will go through a massive drain until it hits around 55% then it will drain normally. I have not changed anything since this started. Any suggestions? I'm thinking I may need to calibrate my battery.

That sounds like a good idea for your situation.

Thanks for your input. I want to wait a few days before I do it. So it will give it time to see if that really is the problem. This only happened yesterday and today so maybe tomorrow will be better. Besides the only time I really have to do it is later this week.

You charge your battery to 100%, wipe batterystats.bin, then run the battery down to 0%, then charge uninterrupted back up to 100%
Battery Calibration does it help ?
I have a similar situation and i followed the battery re-calibration method too but still didnt help.
Situation - The battery would charge till 88% but will show its fully charged. Recently put Vivokat so now its even more prominent. Every reboot drops the battery by steps, like i would reboot and the battery would go from 80 to 65 just like that, no gradual decline or anything. And even after a full charge (the green light indicator is on) still the battery would continue charging.
Tried - I tried resetting the batterystats.bin file as suggested, fully charged till 100% then removed batterystats.bin file then allowed to discharge all the way then charged continuously till 100%. No outcome
Anything else that can be done ?
Hi,
I keep getting multiple views when search the forum regarding CORRECT method for charging One for first few times and then after. Kindly suggest if you know for sure.
Many Thanks...
as allways: full --> empty --> full
most say two or three times is enough
Do it again when you install a new ROM or kernel

don't know which thread but i remember reading about not to drain it down to zero, suggesting to charge when down to around 5%. Hence the dilemma.
Give a hint if you find it again. I haven't read it before
I'm doing as written and have a quite good (in comparison to what you are reading here) battery statistic.
Would you charge it power on or off for first few times?

You have a li-poly battery, and a lithium polymer battery doesn't need any particular charge method or charge cycle... However there's two things you can consider doing for your phone's battery.
1. Charging the phone for a full 5 hour period (even if it shows 100% charged, keep it plugged in to the end of 5 hours) and then wipe battery stat in cwm recovery if your phone doesn't detect remaining battery correctly.
2. Charging it from 50% remaining battery life is much better than letting it go all the way down to empty!
(I know lots of people told you to let the battery drains completely and then fully charge your battery, but trust me, i'm an electronic engineer, I know better, both draining the battery to 0% and charging it to full 100% are bad for your battery life, those were for ni-mh batteries not li-poly)

Exactly. No need to do full charges. Just plug it in whenever. If you are anal, then keep the charge cycling low. Eg keep the battery on a small band of charge state for example 50%-75%.

So, when the phone battery is down to 50%, we charge it.
And then when charged to a 100%, let it stay charged for an additional 5 hours, after that, or 5 hours TOTAL, from the time it is plugged in?

5 hours total, the point of this is to let your battery voltage go to it's maximum capacity (something around 4200mv, you can check the current voltage by dialing *#*#4636#*#* in your phone and going to battery information section)
And also note that full 5 hours charge cycle is just necessary when your phone doesn't detect your battery remaining percentage correctly... In normal situations just charging the phone from around 50% to almost 100% is an optimal charge method and you don't have to do the 5 hours charge...

The point you're trying to make is that for better battery life, it is important to re-charge when the battery falls to 50%, and not wait till it drops to 5-10%. Correct?
For Li-Po batteries, how low is it okay to let it go, before a re-charge?

Exactly...
It's better to charge your phone between 35% to 75% (optimal value is 50%) and not letting it go under 35% but after all as I said there is no need for an specific charging method and this precautions just give you something like 25% more battery life (and battery life is overall life of your phone's battery before you have to replace it, not the 100%~0% duration)
