I believe you need a rom in the phone to get it to charge. New batteries normally do not come charged. You can get a battery charger from ebay for only a few dollars ( I just found one for $3.99).

Or you could find someone with the same phone and ask them to charge your battery, so that you can flash again...

Thanks for the informations, I think I have to find my friend to chanrge the battery for me, so does any HTC phone say Prophet and Hermes use the same battery model as Wizard??

Only 0% or 100% batt but nothiung in beetwin

Everything was just fine until yesterday when i realized the batterty's built-in monitor wasn't reading a real batt stat. I was sure I was running out of charge and the divice was still saying there was 50% left. I did a soft reset and my atom didn't boot. I took the battery off and waited more than 3 hours, put it back and couldn't boot. I haven't ever done anything to my mobile. No register tweacks, fisical hits or rom upgrades. I searched the web and found a procedure to get it back. Reset+camera choose 1 option and there you go with your device booting at last. I did so but when it ended whith the system loading proces it sent a notification saying that the battery was exhausted and it went off. Again it couldn't boot in a normal way even with the ac adaptor plugged in. I made sure the battery was fully charged. I did a bootloader again (reseat+camera) with the usb connected and i could get it back again but showing 0% battery indicator and would turn off as soon as i unpluged it. I tested the battery with a multimeter and even when it was fully charged i tried to recharge it until green light then i turned it on and the batt monitor was 100%. I could unpluged the usb and everything was fine. It didn't turn off but the indicator got stock in 100%. After an hour or so of normal use i was sure the battery was 90% or less while it was still indicating 100% of charge. I did a soft reset and couldn't boot again. I think the device knows when the battery is 100% charged but when it is less tha 100% and i do a soft or cold reseat the mobile thinks the battery is 0% and won't boot.
Yes, I have ugraded to ROM Xda-Atom-Exec-ENG-20060721-MOT0822 to see if this fixes it but now i have a rom-upgraded aton exec with the same fatal error.
I am at work rigth now and hopping my atom doesn't need a soft reset because if so i need to plug it in in order to be able to do a reseat+camera and wait some minutes until green ligth shows up. My atom knows 0% or 100% of battery charge but no numbers in beetwin.
Any ideas?
did you charge the battery for 8 hours on first use, continuing to discharge battery completely first three charges?
This is crucial for battery performance I now get at least three days of moderate usage and at least 7 days in standby, my advice is go buy a new battery follow the instruction manual completely, failing any changes (be sure to buy battery from somewhere you can get refunded) return the battery. Try also reflashing using bootloader mode, not using the SD card!
The last time i used bootloader was after hard reset a no card inside then i performed the last ROM upgrede available from O2. It seems to be a hardware problem more than a software problem as i thought at the begining.
I hope you are rigth, i guess the device gets charge information from the battery and the battery is telling it when it is 100% and 0% when it is under 100% and after a soft or cold reset. I am going to drain the battery all the way down and recharge it up to green light to see what happens. By the way i did not charge the battery 8 hrs when new.
Where do you think my atom is geting the batt charge information? From one of its inside sensors or from batt circuits?
Thaks for your advice.
I mean reflash using bootloader mode, ie. enter bootloader then plug in USB and run DSUU installer from your PC. Its hard to say where the fault lies, some Atom's had power management issues and O2 are fully aware of it, if yours is still under warranty I suggest sending it to a service center but be prepared to be without it for at least a month! (should change their name to SLOW2) and also be prepared to have it returned to you only to find they havent done a damn thing!
Its a bad battery, same thing happened to me. Just return it for a new one, the material is moulded with the smart chip inside there is no way to fix it.
Now my battery is beetwin 100% and 85%. I have searched other forums and i found out it is definitly a battery issue. It has been more than 6 months since i bougth my Atom so i have no more battery garanty. I thing i am going to wait before i buy a new one in orther to get the most of it since it still last more than 2 days.
Thanks for the information.
when a battery xp-02 (for atom family) is sometime stop at certain percentage, says 72% for long time, i do a soft reset and it drops to says 40%, is it a symptom of bad battery? or it is a ROM problem?

have you checked that your backup battery, the one built into the phone is fully charged before you take out the battery. (check in your settings menu under power)
i have replaced mine from a totaly broken xda (picked it up on ebay) as mine had failed and would no longer hold a charge for more than a few seconds.
i also had major probs with a hi powered battery it kept failing for some reason, totaly losing charge in a mater of hours on standby and this kept hard resetting my phone. so i no longer use the larger batteries.
The backup battery is fully charged
After have taking off the main battery about five minutes and putting on a fully charged one the back up battery might shows the power percentages about 25%.But It almost takes me about 30 seconds to change a another new battery,it's not possible the backup power's problem. I change battery exactly the same way when I do it.That's just too weird it sometimes hard reset and sometimes just doesn't.

The backup battery is fully charged even after having take off the main battery for three minutes!so there is nothing to do with the backup power.
I change battery exactly the same way everytime.Why just sometimes it gets hard restted and sometimes it doesn't.It makes me wonder.
Is this eda ii a broken one?Maybe I should turn it back to the repaireman's house for a few weeks?you know how bad China's services are ,they never do things that customers need.
Thanks your heartkinded help anyway

Thanks the same way though your idea seems not where the problem at.
like i mentioned it could just be because one of your batteries has an intermitant fail, as i said i had the same problem with a hi capacity battery, it somtime hard reset my phone for no reason.
just try buying a couple of new batteries, or lable your batteries and see if its only on one of them that the HR occurs.

Runs only on charger - broken phone or battery?

Yesterday everything was OK. I flashed my phone to newest version of OpenEclair, put phone on charger (like every night) and then went to sleep.
Today, when i plug phone off charger they automatically turn off. When i plug charger on the phone is running ok, but everywhere (eg. in Spare Parts) they shows that battery is 0% charged, battery level is Good (100%), and battery temperature is 67.7*C (153.86*F).
I tried to insert other battery to Phone. I found that, Nokia BL-5C battery have similiar parameters, but everything was identical to situation on original battery.
What may be wrong? What should I do?
Sorry for my bad english.
Use the recovery image in my sig if you don't have it already and wipe battery stats, reboot and let the phone charge fully.
Doesn't work.
Now the situation on
HTC battery & charger: phone turns on (on power on blink one time red) and after 1min they shut down without any information
Nokia BL-5C battery & charger: phone turn on (blink one time red) and still runs without any problems.
I'm not sure, is that battery or phone disfunction? Important is that Nokia BL-5C battery has only 3.7Wh. HTC battery has 4.25Wh.
Damn your phone is 2x hotter then mine xD
its only shown temperature, i dont believe [and dont feel] this temperature

My comment was assuming he started with a full charge in the first place.
Reboot the phone and use it normally, but don't charge until it shuts off.
Recharge the phone completely and then use as you normally would.

I have bought new battery for g1, and this problem still exists...
Is any program or anything, which "cheats" system about battery?
Phone can run out of charger only in recovery menu - at normal theyre shutdowing because of low battery.
Can i do anything without visiting service? Any ideas?

Sounds like phone. A new battery would've solved this problem. Why do you not wanna visit service? Just unroot and demand a replacement.

Charging new battery with NAND

Hello guys,
I'm buying a new standard battery because my current one is going bad. Meanwhile, MAGLDR is known of not charging battery correctly while the phone is off. What should I do know since I heard that new battery must be charged first while the phone is off. Thanks.
The new battery will come with some charge in it. It will not be empty. Lithium batteries do not have 'memories', you do not need to give it a full charge to get the best performance out of it as you used to have to do in the old days. Google for Lithium battery information if you are unsure.
Don't worry about it
Insert the battery, boot into Android and charge it.
Afterthought...
If you are worried however. Just backup your build, flash Windows Mobile back on to the phone. Turn the phone off and charge it with the phone off. Then flash MAGLDR again and recover your backup build.
thanks man, I heard about that too but what makes me doubtful is if that's correct then why almost all phone manuals instruct us to charge the battery until full before turning phone on for the first time.

From personal experience I can say it's pointless to charge full while the phone is off.
All i do everytime is use the charge the battery came with untill the phone turns off by itself, then turn on and plug the charger for 16 hours.
If you do this - full cicle - several times in the begining, the battery is working perfectly.
This way the cells are loaded to the maximum in the begining and the battery is "conditioned"
the use of HD2 with Android is quite a different issue...
Dont know bout all builds(I have nexusHD2 1.9a) but I charged my battery after my phone went comatose-just connect the phone to power with battery and -then- turn it on.If that doesnt work you can always buy el cheapo charger from Ebay.
I bought new battery from ebay,which works great.10$(M | less)for battery+charger.
Cheers
damn, so many different thoughts about li-ion battery i don't know which is the best one.
anyone else? before i receive my new battery tomorrow
