ok so i just bought a ppc 6600 second hand and its great except the backup battery doesnt show up at all under power and i get that "backup battery os low" msg and icon each time i soft reset. i was wondering if maybe it needed replacing or something. Right now it does not even show up AT ALL when I click the er menu. It only lists he main LiOn battery. Anyone know where I can butty the battery and how to replace it if it needs replacing. I actually get a "Backup battery is very low" message each time I soft reset so is there some way to maybe charge it?
you could test the back up battery by taking the main battery out for 20 mins then seeing if all you info is still there. but be prepared to lose your data so back it up.
Im not sure how long the back up battery should last for but 20 mins should give you a good idea. Regards to replacing the battery I have no idea sorry
I've got the same problem, low battery message each soft-reset.
No indicator in the enery program and if change SIM i lose every data.
I give it back to assistance....I can't see other way.
I got this, and this is what I did, but I don't recommend it in case it's a bit iffy.
I took off the main battery and stuck it in the cradle (the device) and it gave a red LED. This kind of worried me, so after 15 mins I took it out, replaced the main battery and over a four hour period, the backup charged.
Hope it helps,
Joe
Greetings! First Off I'd like to say xda-developers rock! I've searched high and low for a solution to my prob and cannot quite find one. My Jasjar has a very hard time coming on. Most of the time a soft reset will not do the trick. I bought a brand new battery with no luck. If you take the battery out, wait about 4hrs or so, and put the battery back in sometimes it will boot to winmo and work fine for about 15min. then the screen will fade leaving blue lines across. After that it unresponsive even if you try to charge it. The battery meter in the phone reads 100%
Things I tried/done:
READ THE WIKI
reflush with several different roms.
bought a new battery
check the internal battery
shocked the internal batt with a 1.5 AA bat like mentioned in a post
updated/downgraded boot loader.
I'm at my wits end with this. I love the phone but i might have to sell it on ebay.
PLEASE HELP ME!
what internal battery are you talking about and where did you get the new one?
I got a new external battery from ebay. i used the voltmeter to test it to make sure the correct volts are putting out. and it was
UPDATE: When I plug in the charger, the light stays red for about 1min then goes off. I double checked that the battery was in secure while it was glowing red. Any ideas?
My Desire suffers from the following problem: whenever it's connected to AC, it will charge until 100% but then after some arbitrary time period it will discharge quickly to 90% after which it will slowly charge again until it reaches 100%. This can happen two or three times each night. This means that if you take your Desire out at the wrong moment, the battery charge will be at 90% instead of 100% which is EXTREMELY annoying.
I'm thinking that there must be other Desires with this problem, since my previous Desire (which was replaced because of WiFi-problems) exhibited the exact same behaviour. Does anyone else notice this? Or is anyone else willing to check (by means of using Juiceplotter overnight) if his/her Desire suffers from this as well? I just can't believe that the two Desires that I own/have owned are the only ones suffering from this ...
I already contacted HTC Customer Support and they told me that they would pass on this information to another department.
It's common... even I have it.
Whether it's a security or a bug (or both!) is completly unknown at this point I believe.

This has been discussed many times, and the concensus is that it is normal. When battery fully charged, it will stop until it falls below 90% at which point it will charge again.

My HTC Hero did not behave that way, and HTC did not explain to me that it was intended behaviour either.
Also, that would mean that the battery plot is incorrect since it shows rapid discharges from 100% to 90%, such as in the following image:
Furthermore, it seems that this problem (or feature ...?) disappears on at least some devices after rooting.
It seems to happen to me more often than not when I take the phone off the charger each morning. It's annoying but I need the phone on, so charging it to full while turned off each night's not an option.
This is usually done to exercise the battery.
I worked with developing a phone, and we did the same thing, in order for the battery capacity not to degrade because it keeps trickle charging at 100%.
So you shouldn't worry about this.
same happens to me, however i charge it over night and when i get up in the morning uplug and it charges for another 30mins (whilst i get ready for work) and its back up to 100%/99% which i can live with

Hm, my HTC Hero did not have this 'great feature'. I'd rather buy a new battery when this one has degraded too far, instead of having a not fully charged almost 50% of the times that I unplug it.
It would be more acceptable on a phone that would be able to go for at least 48 hours without intermediate charges but clearly, the Desire (just like most smartphones) can't do that.
first, apologise for reviving an old thread.
but it seems that charing by usb (via pc) does not have this problem.
also, charging by ac causes the battery to discharge at a faster rate...
Battery falls to 90% as soon as I unplug the charger
Same problem here, plug the charger before I sleep, at the morning the battery widget indicates 100% and the phone light is green, then I unplug the charger and suddently (really suddently, I mean quite instantly) the charge indicator falls to 89-91%.
Considering the poor duration of a fully charged battery I'd prefer not to lose the 10% of the charge before start using the device.
I'm quite sure this didn't appen with 1.15 stock ROM, I suppose I'd noticed it in case...
I can't remember if this appened after FOTA update from 1.15 to 1.21
With 3.1 modaco ROM I had this problem and now even with 1.23.351.1 Build rooted and A2SD+.
I tryed different radio ROMs without results..
I contacted HTC customer support, they told me to use an app manager like Taskiller to close unneeded applications that drain battery... lol
Obiouvsly they don't know anything about this problem..
Any ideas? It really hurts me to start every day with 90% of the battery!!
Thanks to all!
Hey, I have the same problem since I updated OTA version 1.21, never happened to me before with 1.15. Now when I wake up, I have fully (100%) charged battery, but after a minute or two it instantly jumps to 92%.
Any solutions?
Same here after the last update.

I've just sent a e-mail to the customer support of HTC explaining the problem, as soon as I have an answer I will post it here.
It should be interesting to do a factory reset and test with a recharge without installing any other stuff. Is there anyone who have a standard ROM (not rooted, original kernel) and want to do a try?
While I was writing they answered... They invited me to go to the nearest collection point to test another battery if available.
I'm starting to think the problem is not hardware related if other of our devices started to suffer the problem after the update..
I'll contact them again and we will see what appens.
Meanwhile if someone want to try what I suggested, it would be really apreciated.
Customer Support official answer.
The official answer: Send the device to us for repair. First try with another battery if you want (an if you can find another one...).
I'm not too happy to send my 3 weeks old device to them for 20 days so maybe I'll try to flash the 1.15 or 1.21 official ROM to see how the battery works. If anyone with the same problem wants to try to downgrade, please do it just to help to understand which is the problem.
I am having exactly same problem, i dont think its a battery issue either :/
Is there anyone who rooted and "desire" (wow, what a joke! ) to try a Froyo ROM to see if the problem persists? I suppose it should be totally different from 1.21 or 1.23...
I feel a bit lazy at the moment , I've just done a good setup and I'd like not to redo it again....
Volunteers?

Mine is not rooted. I didnt have this problem before the update.
I have some apps installed and a few widgets but nothing "advanced" like different launcher, heavy widgets. After the update I did a hard reset and didn't even backup my settings (have contacts and e-mail via Exchange server). The hard reset didn't help at all...

So I understand I'll be elect "the" volunteer
Maybe in the next days I'll try...
I used the phone till it automatically switched off, pulled out the battery for one minute, tryed to charge the phone when totally switched off and it charghed and stayed at 100% so I'm quite sure it's a ROM related problem.
You can see the next charge in the attached image (thanks to JuicePlotter)...
Battery charge indicator 2.3.5 upgrade problem
Hello everyone.This is my first time come to xda-developers form.I'm from china.
Yesterday I update my wildfire S(China mainland Edition)to 2.3.5+Sense3.0 lockscreen(Taiwan Edition)'s ROM.
I charge my bbttery yesterday evening.I turn off my phone.
When charge compalate.I found that the LED light didn't change green.It was still orange.
Why?How to solve it?
PS:Maybe my post have some Grammar problem。I hope that you can Bear with it.
Try factory reset see if it helps.
Backup important information and personal stuff first.
Just try the procedure of taking the battery out, sim card, micro sd etc etc and see if that works...
are you using the stock battery?
i used to notice with my (so called) extended battery 2430mah Gold battery, the software would say it was 100% charge, but it stayed orange for around another hour or two, then eventually turned green...i assume this is because the phone software had misjudged the charge level...so although it THOUGHT it was 100% full, it was actually still charging?
so if you have changed the battery at all, leave it charging for a bit longer (only an hour or so) and see if it goes out?
should be safe, as the batteries themselves usually have an auto shut off safety to stop them from being over-charged.
I get the exact same on ALL custom ROMs, never on Stock though, would love a fix!

Since I unlocked my phone's bootloader, rooted and installed custom recovery I have the same problem too.
If I charge the battery with the phone turned on, the led turns green at 100% and everything is fine.
If I charge the battery with the phone off, the led stays orange forever even when I disconnect the charger. Then I have to remove the battery and insert it again so that the led turns off. If I wait enough time charging the battery reaches 100%.
This is a strange sympton that only started with the rooting/recovery flashing process.
Oh and BTW the way, I use stock battery but now I'm waiting for the arrival of two batteries I ordered on eBay.
One is a Li-Ion 1500 mAh and the other a Li-Polymer 2430 mAh.
Will see if the same happens when they arrive but I'm almost 100% sure this has something to do with the bootloader unlocking process.
Does anybody know how to fix this? I would really appreciate it.

I for example left my phone charging for 8 hours (during the night) beyond the normal charge time. And the worst is that I have to remove the battery in order to turn off the orange led and be able to turn on my phone...

have you try to wipe battery stats in recovery mode?
perhaps this will help, although I had not previously encountered a similar problem

Same as, pain in the arse!
Great news! At least on my phone this problem is gone.
You wonder how? Simply by updating recovery to v5.0.2.8 from ROM Manager.
I almost didn't notice it it but a few hours ago I plugged my phone to the charger while still on. After finishing my work I turned it off (no fastboot).
In the meanwhile I needed to use my phone far from the wall plug and disconnected the usb charger cable.
My gesture was to immediately remove back cover to remove the battery but fortunately I noticed the orange led went off.
So I decided to plug it again and wait for the charge to complete and for the green led. It did!
So run to the Market, download ROM Manager and let it update your recovery to the latest version.
I hope this annoying pest won't bother you no more.

thanks, i will definitely try this, ive been having a hard time looking on ways how to solve this problem.. also can i now do battery calibration steps after that?
cause im having battery drain issue on my WFS after flashing of ROM, im not getting 4.219V my only maximum was 4.196V. And yesterday i tried charging my phone in OFF state for 7.5hours and when i open it 100% at 4.077V, and now 87% just after 15mins of use..

Hi guys, I'm experiencing some power issue with my ZL. I have recently updated via Seus to .283 firmware....once I reboot, it gets to the Sony screen and then it shuts down. If the phone is plugged in it boots fine and remains on. The battery charge shows 80%. Afterwards I unlocked the bootloader and flashed the KK advanced kernel to see the battery percentage in recovery and it also shows 80%. Is there anyway to check if its the battery without replacing it?

There is a battery testing app for Sony devices (you can find it here), but, obviously, it requires your phone to be able to stay on battery power for the time of the testing...
What happens with your phone if you unplug the charger once fully booted? Does it immediately shut down, or is only happening during startup?
The phone shuts down immediately after I remove the usb cord. Offline charging looks as though it's working. I'll see what the app says, thank you.
* btw the phone stays on when in recovery which is odd
* the battery app requires you to remove power which I cannot do
* help me!..using a Z Ultra at the moment...things huge!

Well, yeah, that's what I meant saying the phone has to be able to stay on battery...
I think (just an uneducated guess ) that the recovery doesn't have a mechanism to analyze battery health/status, but the Android OS does (and so does the bootloader). That's why it stays on in recovery, but when booted (or in the process of booting) into the OS, the system somehow thinks that the battery level is too low, and shuts down as a safety measure. I have seen multiple times that the battery levels shown in recovery and in Android are drastically different, which kinda confirms my thoughts...
All in all, it looks to me like your battery is acting up. Just to save you an effort and expense of getting a new battery, at least until you know for sure the battery is the problem, I can suggest something to you... I am expecting a replacement for my battery in a day or two. My old (current) battery still works, it's just old and doesn't last very long, that's why I am replacing it. I could send the old one to you (Vancouver to Winnipeg is not a big deal), so you can try it out to pinpoint the problem. If it works, then you know it's the battery, and you can either buy a new one, or keep my old one for the time being. If you are OK with the idea, just send me a PM with the address to send it to.
I think I'm just going to buy a battery of ebay. I really appreciate your offer to send me your old battery, but its probably best I go new since I don't want this issue arising again. Thanks again for all your help.

No problem! I was just thinking you could use my battery to confirm the problem before buying the new one, not to keep it for the long term, of course (that would be silly). But I am pretty sure it's the battery, anyway... Good luck!
I was wondering if the battery ever fixed the problem, I am having the same issue
really mad, I'm going on a business trip and this started happening. this week I updated the firmware to 293.
I didn't know you could replace the ZL battery.
After 2 years of use, my phone suddenly just died when I was playing a game. It won't boot without the charger ever since. I'm so sad because I expected this phone to last longer
