Yeah, I was able to do that as well. However, nobody mentions whether or not they were using the unit while in the chargers. I don't at all, and rarely do I use it when in the usb link either other than as a telephone with a Jabra BT500 bluetooth earphone. The screen isn't on or anything like that as I use voice commander. with the screen shut off I really don't know whether the system will shut down or not now that you mention it. Never gave it a thought. Generally there is slightly different circuitry involved with mains power and battery power but I would think that would not involve anything other than the power input circuit. Good point. Like I said, I am not an engineer. Will need to put the thinking cap back on I guess.

Went to town today, games, mp3 for 1.5 hours, mp3s 1 hour, games & mp3's 1 hour, more mp3s for 3 hours, then the trip home total running time around 6 hours more or less of mixed usage. had 40+% battery when I got home. But they are still giving grief to the guys who are still taking them in to SiS in Singapore telling them it may need a new battery, or MOBO or co-ax. ad nauseum. and now telling them there is as worldwide shortage of MOBO's so may have to wait 2 or more weeks. The guys over here are ready to burn the building down.

Good Question,

Whenever my Exec shuts down when the battery is at around 70% (after about 2/3 hours of full charging); I plug it into the mains and then it is perfectly fine, I can listen to MP3, play games, be on the phone, etc without a problem. So dont know what the problem is exactly.

Cheers
[JASJAR, XDA Exec, MDA Pro General] CWKJ:
Some observations, not sure if the rest of you have the same obseravtion,

i) Using UMTS/3G/GPRS surfing internet, shutdown happens at around 40%

ii) Switch to GSM mode, without doing anything, can reach 34% before shutdown.

iii) WiFi mode, downloading email, shutdown around 60%.

iv) Accessing SD Card (playing songs), around or below 45% [update 1]

i), iii) & iv) may explain the heat theory because some form of wireless transmit and receive is going on, where else ii) activities is minimum.

But why, in my case I can surf net (i) or down email (iii) or playing songs from SD (iv) at higher % and no shutdown?

"Questions,

Step 2, how do I know it goes dead? I waited till bootloader message "Serial v1.00" disappear, I thought it is flat, but when I try to bootup (step 3), battery indication is not 0%. I put it into bootloader from where I left off, is it ok?

I also realised that it hit 100% to 30+% in just few hours, but it seems to take very long time from 30+% to 0%, is this normal?

Step 3, do I charge in bootloader mode or normal operation mode?"

Step 1 to 7 does not work for me. The Problems still happens. [update 1]

Problem (ii) seems to be gone after Step 1 to Step 3 only, but Step 2 only managed to discharge to 14% and seems not able to go down anymore. After Step 1 to Step 3, now it can go below 34% without reset and it has reached the Orange Colour portion of the battery indication. But problem (iv) still occurs, so suspect (i) & (iii) may still occur . Maybe after ROM upgrade, the phone is just like new and the battery needs to be charge again to full 1 time and immediately drain (normal usage) to low 1 time to tell the stupid software where is 100% and where is 0%. And maybe certain activities like (i), (iii) & (iv) may trigger some form of protection of the software [update 2]

Hi there, I'm suffering from the same issue after ROM upgrate to laster official... and like most of you I did go for a new battery, even 2 of with extended capacity, 3200mA... end guess what? the Problem is still there just a bit delayed with new batteries... so I do suppose a ROM issue. And Now, since yesterday, I've put on my Universal the Ivan's Coocked AKU 3.2 ROM and I don't have the battery issue anymore.... so, I really guess something wrong with the latest 1.30 ROM from HTC, whatever brand you have, as I've also read several threads on several sites and all had suddently this battery issue after a ROM upgrade to latest.... OK I'm only running new ROM 24h by now, however I did extended test...... I hope HTC will soon release new ROMs with the official AKU 3.X for the Universal.
[JASJAR, XDA Exec, MDA Pro General] vikasmal:
Thats great that you managed to get the full battery life again after using the other rom. My problem definitely started after I upgraded to the new O2 rom.

I wonder if anyone else has had success with the battery after upgrading to another ROM?

Anyone?

Thanks and Cheers.
[JASJAR, XDA Exec, MDA Pro General] bohr2005:
Just upgraded to several other roms. Had same problems with each roms. Now i have upgraded to new t-mobile rom. same problem. put in new non oem battery 1600. no problems now
[JASJAR, XDA Exec, MDA Pro General] XzaniX:
after several days, with AKU 3.2 Beta ROM no problems anymore with OEM battery... :?
[JASJAR, XDA Exec, MDA Pro General] vikasmal:
Finally great battery life with new non-OEM battery.......

This battery issue has really gone out of hand and am amazed that HTC/O2 are not doing anything about it, least of all they should replace the batteries. The problem I was having was the same as mentioned earlier, 70% and the battery would go off and nothing could restart it except for plugging it in the charger again. Really shocking how in 7 months the battery could go like this; it is deplorable and reeks of bad manufacturing/design.

I finally went and bought a replacement battery from www.gpsforless.co.uk , one of the large 3400 mah batteries with a replacment back cover and thankfully all seems fine now. Battery is alive till the end (I went down till 5% before recharging again); and the best part is that I can use the phone for two days without recharging (with heavy usage of telephone, some wifi, some games/lots of texts, etc).

Guess it was/is a battery issue then.

Cheers.

sms & others

didnt quite follow all that tech discussion but i hope what i have is just a battery problem that will be fixed with a new batt and that i won't have to send my o2 to SiS KL and have to pay for it.
[JASJAR, XDA Exec, MDA Pro General] cmonex:
let us know if it got fixed that way!
[JASJAR, XDA Exec, MDA Pro General] Patrick PPC:
I had my Dopod900 (O2 Exec equivalent) repaired & collected just yesterday. Coaxial cable & mobo replaced as claimed. However, it still shut down at around 32% while playing a video clip at full brightness display. My battery has not been changed. I am not sure whether the cause is due to battery? May be the LCD display required more juice to power up or there is a design or product quality issue considering the high numbers of reported cases. This HTC product is really crap & inferior!!
[JASJAR, XDA Exec, MDA Pro General] Patrick PPC:
Did an experiment just 1 to 2 days back.

I bought a new OEM battery. Replaced my old battery with the new one. Did a full charge for about 12 hrs. Run a movie clip on full brightness display. Monitor my set on & off. The battery power went as low as 3%. Before this at 9% power left, there was a popped up warning message announcing the main battery life is low. Decided to switched off before the set got shut down.

Another folk had tried with a new battery. Let it run & finallydrained out at 1 to 2% available power.....(see ppcsg.com forum)

My guess: the battery may be deterioriating with each charging.

It may be good idea to charge the battery on a standalone charger. On the old battery, I will like to discharge it fully & try a full recharge for 10 to 12 hrs to see if the life can improve to an acceptable %.. If still no good, this goes to show the battery cannot last long..
[JASJAR, XDA Exec, MDA Pro General] Condex:
I had the same problem with my Universal since I dropped it. It all worked fine afterd rop apart from it kept switching off long before the Bat indication indicated it was low.

I have seen several other post on this and posted a couple of my replies there also.

I bought a new battery (take hints from several others observations) and now every thing is fine.

The batteries last approximatley 6 months according to some suppliers. Mine made it for 12 months but the impact seems to have been the last straw.

There have been some threads which talk about the batteries having internal monitoring chips. The original may have a proper current monitoring system and the copies have another type of chip which is not as good. I think this apllies to our PU10 bats but not sure.

Anyway if the bats do have monitoring chips in them this may account for the drop affecting mine. (original Bat) and the starnge bat behaviour in the copies.

In summary NEW BATTERY fixed my problem. simple as that

[JASJAR, XDA Exec, MDA Pro General] HBK:
My old Magician also started switching off at a relative high charge. About 50% when running GPS or under similar stress, and 25-30% at standby. So nothing Exec-specific about this problem!

There's a lot of hear-say about Lithium batteries, and I don't pretend to be able to seperate the whole truth from myths. But there's a few facts that no one in the business seems to argue about:

Fact 1:

ALL lithium batteries have a chip controlling the charge level AND reporting it back to the phone or whatever. So yes, the battery DOES in fact tell the phone how much juice is still left.

When several batteries of the same type (for example 1750 mAh) have the same problem, it is more than likely a problem inside the battery. Noname batteries often have a cheap (read: bad!) power control chip.

Fact 2:

Fully discharging a Lithium battery is NOT a good idea! At least not on a regular basis, or you WILL kill the battery before its time. They perform better if they only get discharged a little before the next charge. But be aware that each recharge takes a bit of the batterys life, so either way you loose. Some manufactures recommend fully discharging if the reported power level doesn't match the actual level. Discharging should ONLY be done by using the battery in the device it was intended for!

Fact 3:

Expect max 500 days of use or 500 recharges from your battery, before it starts acting strange. As lithium batteries get older, they often 'overestimate' their own charge level.

For example, my older Sony digicam started reporting increasing standby time, going up from 65 to 90+ minutes. At that time the real standby time was closer to 30 minutes max, before it shut down. Does that sound familiar?

Fact 4:

When the time is up, don't fight it, just buy a new battery. Preferably an original, or you might end up fighting a bad chip!

This is lithium-ONLY info! Completely different rules go for the older types, but who cares about those? :)
[JASJAR, XDA Exec, MDA Pro General] cmonex:
as for fact1: depends on the device also... i noticed my qtek9000 will warn for low charge level with an aftermarket battery which otherwise doesnt report its charge level too well. but the qtek does notice in time when its low... so theres another monitoring system too.

absolute disagreement on the 500 day rule. i have batteries (li-ion) that are 5 years old, and they still hold at least 80% of their capacity :)

edit: i almost forgot about my 8 year old li-ion batteries from 1998 :) one of them has about 60% of its original capacity... the other has 80-90% and the latter clearly has better quality cells, even though its just a sample from sony (the battery of a preproduction pda)

i again forget.. i have even more batts from 1998, that are still good.. well i tend to forget how many as i have about 50 li-ion batts or so in total :)
[JASJAR, XDA Exec, MDA Pro General] HBK:
Absolutely! The device has to pick up the data sent from the battery and process them.

That's 500 days of usage, you know. Not a built in time bomb :) And of course you can get more than that, with a bit of luck. But most manufactures quote a life span of 500 days of usage. Only the bold ones go as high as 1.000 days/recharges.
[JASJAR, XDA Exec, MDA Pro General] cmonex:
about the monitoring, this second system doesnt care about what the battery reports about charge level- not sure i understand your point

no i didnt know you meant 500 days of usage. exactly what does usage mean? :) these batteries are in use everyday, if nothing else, keeping the RAM alive
[JASJAR, XDA Exec, MDA Pro General] HBK:
cmonex,

Not that many moons ago :) I read a brilliant posting about contemporary batteries. It was written by a guy in the business and explained a LOT. Killed a lot of myths too. Unfortunately I have been unable to locate the link for you, but no doubt a Google search will give you some great links on this subject.

Good luck, and have fun. It's actually very interesting reading :)
[JASJAR, XDA Exec, MDA Pro General] cmonex:
i read through batteryuniversal a few times if thats what you meant here :) at least Menneisyys (if the name is familar) always refers to that site.

i don't have any myths about batteries, but am not willing to believe theories that experiences conradict with, or obscure theories that don't explain the fine details so they can be misunderstood easily, such as the 500 days of "usage" as the lifetime of a li-on battery.
[JASJAR, XDA Exec, MDA Pro General] HBK:
Sorry to say, but I really don't care that much :)

I have done my share of reading about how batteries work. I really can't be bothered that someone somewhere in netland see things differently, and I am certainly not going to spend the rest of my life explaining the whole population of the planet individually how lithium batteries work, or at least how the experts say they work :)

I came past this thread searching for something completely different, and thought I'd share some of the stuff I have read in the 1.2 million similar threads. If you are gonna use that info or not is up to you. I am outta here. Have a nice day :)
[JASJAR, XDA Exec, MDA Pro General] cmonex:
hi, it is ok. i did hope you didn't take it very seriously. :)

this was about nothing basically, i replied only because i see the same stuff quoted from battery experts over and over again and it is plain obvious that parts of it is just theory (the other part of your original post i didn't reply to isn't like that :) ), same happened with the ni-mh's a few years ago before new experiences changed the theories. li-ion is still relatively new, and i can only hope the theories will become well established in practice too - you see a lot of people still try to handle li-ions like they were nicads or ni-mh's. :) i'm sure this is going to change once and your post may help some people with that too. (as you can see, you certainly didn't need to explain this stuff to me as i've read a lot myself too)

you too have a nice day!
[JASJAR, XDA Exec, MDA Pro General] pauliu:
It looks like the battery level information is stored inside the battery. I have both Atom and Atom Exec, one of the battery showed 100% fully charged, while unplugged the charger, the battery level dropped down to 65% immediately, I put it on another Atom, the battery level was same.

I checked the battery voltage is over 4.2V which is a fully charged voltage, so I suspect the battery level information is stored inside the battery.

I changed back the registry tweaking

HKLM\Drivers\BuiltIn\usbfndrv\EnableUsbCharging

from "1" (enable) to "0" (disable)

and charge it again, very soon it charged up from 65% to 100% , now even I unplugged the charger, the battery level drops normally (ie. 99%, 98% ...)

It seems that the WM5 USB charging cannot update the battery level correctly in some case, especially the battery was ever charged by third party external charger. After "disabled" the registry, the battery level can write to the battery again.
[JASJAR, XDA Exec, MDA Pro General] Patrick PPC:
Did you encounter auto shut down at certain percentage of battery power? May be you should run your set after charging to see if it crashed above 30%..
[JASJAR, XDA Exec, MDA Pro General] Condex:
Now that is interesting!!! Apart from drop my PDA I also had to by a new charger as I left mine in Brunei when I travelled to UK. I bought an Orange charger and used that it chargerd for 3 hours and then the CHARGER failed NO LIGHTS. Took itback they changed it for a new one. That lasted me a week until I got back to Brunei (typical) and then Fail same why CHARGER failed no lights.

But the use of the Orange charger was at the same time that I droped my PDA AND when my battery problems started.

I still have the old battery and my original charger is back in use so must look intio this registry issue and see how it works with the original battery that was having the problem.

[JASJAR, XDA Exec, MDA Pro General] Patrick PPC:
Chk my pda phone but couldn't find the registry:-

Is it found in other location?

BTW, a fren of mine had cut up a lithium battery & told me there was a microchip in it. He is a whiz in electronic stuff & computer. Bought compatible battery & resoldered to get it up & going...Just hope it didn't explode in his face when using his notebook..haha..!
[JASJAR, XDA Exec, MDA Pro General] skywriter:
every PDA i've owned has had a lion battery in it. and everyone has had a deleted capacity to charge over the years. my old ipaq 3100 won't even charge anymore. i won't buy a pda that doesn't have either a replacable battery (prefered) or an extended battery option.

i ordered a 3800mAh battery from expansys august 1st, and today it finally shipped! of course expansys doesn't list them anymore... anyone know why?

Phone shuts down after enabling wifi, gsm, bleutooth, umts

One and a half week ago I noticed that my phone was shutting down when the battery level was reaching 42%. Then I read the article where somebody was telling about the problems with the co-axal cable that connects te mainboard to the display.

Afte some testing I must confirm that he is right. First thing I did was getting a new battery (1750 mAh). The first day it was working fine. But after I charged it with main power (not usb) I noticed that my phone was getting very hot. Tha day I was not using my phone a lot but still it was much warmer then before. At the end of te day with 60% power left I activated wifi, beleutooth, gsm, umts and after about 40 minutes the phone shut down. At first I though that the problem was still there, but as soon I put my phone in the cradle in my car without connecting it to the power supply it started working again within minutes. It kept working with every feature enabled until I came home and left te car. Why was it working in the car? Then it hit me. My cradle was in front of the airco outlet and it was cooling my unit. This morning I activated everything again and within the hour my phone was shuttng down again. When it cooled down it started to work again with the same battery. So I immediatly went to the T-Mobile shop and explained the problem. Ofcourse they never heard of this problem. I will see if the problem is solved when I get it back.

Hi Dear all,

I just bought 2nd hand dopod 900, 2 days ago...

Batttery is dam bad, 80% it start to shut down ...

The past i am using O2Atom, normally i will use battery till it totally flat... Then change another stand by battery, fully flat battery will have longer life span before charging.
[JASJAR, XDA Exec, MDA Pro General] Patrick PPC:
Jojoe,

Go buy a new battery at South Asia or SLS. Along the way, visit Bugis Junction to buy for yourself a traveller charger @ $10 from 1 of the the Pasar Malam stalls there. This traveller charger is a standalone charger that will slowly charge any lithium ion batteries including those used on normal handphone. It has contact points that can be adjusted to make the contact on your battery. Your battery contacts are the extreme bigger ones. The inner smaller contacts are not for charging. Suggest u charge for 8 - 10 hrs for a new battery. Indicator light will turn full green.

This charger is a very good buy. You need to check out if it is working properly before you buy. Bring along any lithium battery to try out.

Good Luck!

Re: General Battery Info

Hello!

I'm just having the same problem with my Qtek. Battery freaks at 54%... :evil:

I hard reset the PPC but the problem remains...

Well, just guessed this may help solve my problem...

At the end of point 2, the PPC was ded and I plugged the charger and started WM5. It was at 39%. I guess that means that made something good to the battery.

Now I'm fully charging again to let it die once again!

I'll try to heal my battery this way, otherwise I'll have to buy another one (my Qtek has 6 months and half old :() warrancy doesnt cover battery :(

Anyway, just thought you should know..

Hi again!

Just did what I've told and It didnt fix my battery!

I recharged it completely and then it hang at 51%

I'll try it tonight again, if it doesnt result, I'll buy a new one!

Any other ideas?

Thanks

My experience:

-first battery cutting off at 35~40% after seven months

-second battery from Honk Kong (eBay, P/N :35H00058-00, made in China): problems, "charging" after cable unplugged, cut off at ~80% on some applications with high energy consumption, cut off at 35~40% generally

-3rd from gpsforless.co.uk (1720 mAh): problems, showing 100% all time, cut off at 35~40%, device not wakes up some times pressing power button...

-4th from expanys (P/N :35H00058-00M , made in Taiwan): all seems ok, first warning at 20%, second warning and SD off at 10%, cut off not checked yet.

Jasjar goes dead at 60 % Battery charge

My jasjar is one year old, and now a days, it goes dead at 60 % charge left on the onscreen battery indicator.

Please help
[JASJAR, XDA Exec, MDA Pro General] :
Okay, my XDA Exec had identical problems and luckily (because O2 just said sent it back) I decided to consult this forum. It is DEFINITELY the battery.

My advice would be to goto eBay and get a replacement battery. There are 2 varieties

a) standard replacement (plug replacement fitting inside case)

b) supersize replacement (take away original battery and battery cover and replace with superize battery)

I bought both and have started to use the supersize replacement for my black O2 XDA Exec. I have the following notes:

Some reports say that only the original parts mesh with the EXEC Power display, i.e. the replacement batteries may always show up as 0% charged.

My supersize battery does not have this problem.

The supersize battery is great since its quite difficult to drain the battery between laptop assisted USB charges even whilst heavily surfing (WiFi hammers the battery).

My supersize is dark grey thus totally clashing with the (now ex) cool black colour scheme of the XDA Exec which now has this big fat grey lump on the back. Still its functional and works fine and avoids the frustration of running out of juice or random powering offs.

Bought a new original 1620mA Dopod Battery and it is okay now. Battery is able to go down to low % with correct voltages.

Does anyone knows if there is a charger that is able to charge the battery outside the phone?
[JASJAR, XDA Exec, MDA Pro General] Patrick PPC:
CWKJ,

You can buy a standalone universal charger around bugis junction walking towards SLS. Several phone accessories stalls (pasar malam looked alike stalls) sell it. You can purchase it at $10 though it is a slow charger. It can be used to charge any normal phone & camera lithium ion batteries too..
