I'm at a loss.
A week ago, phone started random resets and looping resets - usually when using a significant resource (i.e. camera, web).
I removed everything, reflashed rom, reflashed the Cingular rom etc. to no avail - same problem.
Today, I'm running the bare bones cingular rom without add ons. Seems like I'm doing fine - battery down to about 88% at 5pm which seems okay (I push mail from the exchange server). I take a picture with the camera and go to send it via email and the phone starts looping resets. I soft reset and I get a low battery message - 12%. I went from 88% to 12% in about two minutes.
Any expert opinions? Is it just the battery or is my phone turning into a brick?
Thank in advance.
Sincerely,
Jonathan
First off how old is the phone? It could be time to get a NEW battery.. these batteries have shelf lifes.. lol.. there days are numbered.
Phone is about 1.5 years old.
Update:
Interesting update:
Powered the phone off to pull the battery and check it out as I am looking for a new battery on ebay.
When I power the phone up, it now says battery is at 67%
- this makes me concerned that there is a hardware problem with the power management system in the phone...
thoughts?
"bump"
Any help, all. I would really appreciate your insight.
I'd start by buying a new battery. 1.5 years is a long time for a rechargable battery.
I am having the EXACT same problem.
I even bought an OEM Sanyo on eBay. No change. Then, I complained to Cingular and they replaced the phone (it took a LOT of complaining).
I put the new battery in the new phone, totally vanilla install. It worked great for a couple of hours, then the problems started happening again.
WTF? New phone, new battery and it's still happening.
Yeah - probably no way any level of complaining is going to score me a new phone from Cingular because of the age. I have a new battery on the way, but I am worried that it might be something with the charging circuit or something. Wish somebody with some expertise would speak up on this...
If you are lucky: they sell extended batteries on eBay. I bought me one for my TMO USA VARIO. The stand-by times are really amazing!
In case you consider to buy an extended one make sure that it comes with the battery door as pictured at the link below!
In general the prices on eBay are very low, so, if you are planning to keep your phone a bit longer you might want to buy 2 or 3 batteries at once? (Saves shipping and I really expect that the batteries will soon not be available any longer since the WIZ is discontinued.)

I had this problem. Looping reboots, might work for 5 minutes but then a constant cycle of reboots. Mine is a years and 2 months old.
I though it was the phone and was ready to ditch it. The battery showed a good charge.
I bought a OEM battery off of eBay for 10 bucks and the phone has not had one issue since.
No question it was the battery in my case.
Excellent. Thanks for the response. New battery was purchased last week and should be here soon, so I'll let you know how that turns out.
Might also take a look at the extended battery - seems like a neat feature, although it looks like it would keep the phone from fitting in my car stand (I use tomtom with it).
I'll post a reply when I find out if it is indeed the battery.
Thanks again.
Its a battery issue.
I had this problem before.
I would charge my phone using some 3rd party cradle and some how it screws my battery up.
for exmaple. The phone would say the battery is fully charged. but when i use it. the phone only lasts 5 mins.
after awhile. not matter how i charge the battery the battery never went to it's full charge. and like you, it keeps looping.
this was an OEM battery that i had for less then a year.
i got a random cheap battery off ebay to test it. and now it works fine.
i threw out the old battery.
UPSATE
UPDATE: It was..... the battery. Easy OEM replacement off ebay for less than 5 bucks. Running like a champ again. Thanks for the insight. Hopefully this helps someone else in the future.
Cheers!

I recently acquired a HTC Universal for dirt cheap, and have found the first problem to explain the low price: Whenever I'm using a "power-hungry" application (TCPMP, Internet via Wi-Fi) it eventually just blacks out. Full shutdown without warning.
When trying to reactivate the unit, it reboots as if after a soft reset.
In fact, if I try to reactivate it too quickly, even the reboot fails.
None of the above happens when on external power.
This leads me to think that it's nothing worse than a battery that's lost its mojo, but since there is no warning about low battery, and when the reboot finishes successfully even SPB says the battery is somewhere around 70%, I want to run this by you guys.
What do you think? Just go get a new battery, or is there something else going on which will make buying a new battery just a waste of money?
I'd say it's the battery, 99% sure.
I'ts gotten old and its voltage breaks down under load. If you have proper equipment and a glimpse of an idea what you're doing you should drain about 300mA from the battery and measure its output voltage.
You'll most likely see it going below 3.0V quickly.
I'm afraid I don't have that equipment, but all I really needed to hear was that it's probably the battery.
Now I can stop thinking about it and just order a new batery.
Unexpected reboot - Apparently bettery issue
Hey Holybear, my device shows exactly same symptom, If possible let us know if bat replacement solved the issue>

I knew I wasn't the only one withthat problem. I think i've prooved it to be a battery faultt. as if you taake te battery out after it gets to that stage where you just can not get it too complete a boot up without it shuttinng down again
take out battery ,place finer oveer all battery trmminals and plug inn your mainss charger it should now boot up and runn fin off the charger unless your finger slips off the battery terminals. thisshsowws it's the temprature sensor in the battery.
I posted a more in depth reply to a guy in the wm6 threads as wifi heeaating up battery wass shutting off his device as well
@ cyberjak
Hmm, the idea that a temperature sensor in the battery causes this problems is interesting. I'd just expect the device not being cappable of rebooting instantly, because there should be a hysteresis implemented in the battery's protection circuit.
I had the exact same problems and described them elsewhere, but in my case it surely wasn't an issue of temperature.
I'd suggest to take out the battery and wait about an hour for the device and the battery to cool off. Most likely the battery will then take a complete boot but shut down soon after that - without having gotten near to "warm" yet.
If this happens you can be sure that the battery itself is dead without needing to measure anything.
Okay, to tell you what I tried:
I ran the Universal until it spontaneously went dead.
Started bootlaoder to see how much longer it would work on that. Was a bit longer, what with low energy consumption, but soon even that wouldn't stay on for long.
Then decided to try the "old wives' tale" (meaning I don't know whether there's any sense behind it or not) of putting the battery in the freezer for a little while.
When I took it out and let it get back to normal temp, I plugged it in and after a while booted the Universal. It showed 40% battery, lower than it had ever gotten lately.
Recharged for a full day.
Tried TCPMP: went dead after three minutes.
So in my experience the above didn't help battery performance.
Am going to get a new battery in a few days; I'll keep you posted on progress as I try with a fresh battery.
I had the same problem, whenever i did something cpu intensive, it would just black out.
I just bought a new 3100mAh battery. Best thing i ever did. It might be thicker now with the new battery, but it actually feels more comfortable as a phone. Plus the new battery only cost 13 odd quid, so definately well worth it. Oh and it doubles the battery life (3100/1500 = ~2... duh)
Hope that helps.
oh you know wat i have the same problem with my Jasjar and the bigest problem that there is no batteries on market for Jasjars in my country....its looks like im living in Jurassic Century!!!
If you want i can send you a battery xplayer, they're quite cheap here.

I ordered a regular battery replacement, but maybe I'll add a 3100mAh as well.
I could use it as a media player during long train trips.

I revived two batteries by intense cycling to work quite well again. They still black out at 20%, but only under extreme load (active gsm connection, active wifi, bluetooth and having to render a webpage).
But you should be able to discharge them below 25% at least. Else they're most certainly "too dead" already. And you should do at least 3-4 cycles.
My guess would be that the freezer finished your battery off. I don't understand how this method should work anyway, as lower temperatures reduce the time affected capacity loss. Actually the best place to store a LiPo or LIo battery is the fridge, charged about half the way.
But I also ordered two 3100mAh batteries. I'm using the Uni as a laptop replacement and the permanent wifi usage together with some cpu load and the backlight kicks the battery's ass quite hard.
In Germany the China 3100mAhs are overpriced and it's hard to get your hands on an external charger, but on Ebay.co.uk there's a seller that offers battery and charger as a bundle for about 15€. This will give me a solid 6000+mAh per day and should be enough to forget about virtually every setting related to power consumption
@ xplayer
If you haven't donw already, take a look at Ebay.com, co.uk etc and look if one of the sellers there will ship to kurdistan. You may be lucky

Thanx for helping the guy,yo folks on xda are the best
Just to give you all the end of the story:
I ordered a regular replacement and a 3200 mAh one, and both have returned my Universal to a well-used life.
Thanks again to everyone helping me out here.
For you guys does the device switch off only when the battery is low, or any time. Cause I have this problem as well, and I was SURE that it wasn't a battery problem until I read this thread. The phone switches off intermittently, sometimes after only 3' talk time right after it had been charging for a full 8 hours! Also, usually if I let it sit there for a few hours I could then turn it back on and it would last a full day, so I knew it wasn't due to low battery.
The overheating theory would explain my problem, as, now that I think about it, all my seemingly-random shutdowns were during radio activity (making or receiving calls, especially when the phone was searching for signal, or wifi, which would almost instantly kill it). Strange that it overheats like this, most phone batteries simply run out of charge faster and faster until they can't hold a charge at all, but mine lasts almost as long as it always lasted even though it's 2 years old - unless I get the shutdown thing of course.
I asked this in another thread, but since this one is full of people who got replacement batteries I'll repeat my question here as well:
How much thicker than the standard battery are the 3100 and the 4200mAh ones?
I also got this problem recently, so I bought a new battery and although it's only a 1600mAh battery it runs great again
hey roodkapje ive got that same problem with my battery for my spv m5000 the bad news is that i cant get that batery in barbados so im all out to see
Hello! Long time lurker, although I rarely post.
There are some rumors floating around most posts that pertain to charging about the fact that if you leave your phone charging on android you can destroy the battery. I feel this is a VERY crucial issue and have yet to see a firm answer supporting either side (done LOTS of searching )
I think there should be a dedicated post to informing people of whether or not this is true because its a very key issue.
Side note: Been using android exclusively for 2 weeks now, and leaving it charging overnight and dont think anything bad has happend. Thank you so much to all the devs, especially to cortulla and darkstone. Youre the best. <3
UPDATE: The general consensus so far is that even though the battery kernel may or may not be fully functional, the hardware should be capable of keeping anything destructive from happening. :] a professional opinion would be greatly appreciated
i always leave mine connected overnight next to me, havent exploded yet...
In my opinion, even if kernel will be faulty (im not saying it is), charging cirquit still have hardware protection, which will block overcharging battery..
^^^ my sentiments exactly.
Plus, my hd2 gets slightly warm while charging, but seems to cool down when charging reaches 100% (or 91%, or 98% or whatever Android decides is a full charge today )
either way, it seems like the either the kernel or the hardware overcharge protection is doing its job for me.
(That being said, I have just 5 minutes ago, unplugged my hd2 when it got to 100% just to err on the side of caution lol.
now - 5 mins of standby later, its down to 96%! WTF? lol)
'Charged' from 96% to 100% in about 30 seconds though
So maybe, charging/battery status shouldnt be fully trusted just yet
I don't think so. But it's bad for your battery if you let it completely drained.
I've got a second battery. So I don't care if they get damaged Android on the hd2 is worth it.
sent from my hd2.
I don't know think that it would explode, but there is reason for concern. I did exactly that, and the next morning I woke up my phone was hot to an extreme. I posted a thread in the Q&A's about this yesterday morning. Now after I found the phone in that condition, nearly 3 hours later the phone booted on its own to my suprise, I was ready to summon HTC lol. So yah I think there's something there are mechanisms that protect the device from such peril, as I witnessed this myself.
There are hardware measures in place to prevent this from happening. Google ds2745.
I leave my phone on charge all night anyway, never had a problem.
I have always charged my phones overnight. Never had any issues, although between work and personal the phones generally need a charge by bed anyways.
switch it off
unless I'm expecting a phone call i always switch off the phone then charge it.
it won't get hot that way, and when you switch it on its a nice clean reboot no matter what os your using
So, i bought the official HTC extended battery, i had read before buying it, that after it goes flat, if i took it out, i'd have 50% more power. Today, i tried that, and it was true. So, my question is: Is there a workaround? Or, do i need to take it out everytime it goes flat? It's not a bad thing, but it's kinda annoying. Thanks in advance!
No workaround although I have heard newer ROMS work with it.

dang, that's dissapointing.
oh well, at least it actually does last more than the original one.
thanks!
Is this really the case? I thought - at least n Android - it was fine. How can hTC release this if it's unsupported via ROMs?

I dont get your question. Are you running a stock ROM? If you are then it should work just fine. Even most custom ROMS support it. If you mean you're running and Android ROM then you have to find the kernel that supports the extended battery (usually labeled eb) and you'll have no problem. I have the extended battery and have no issues with it. I'm using Dutty's ROM.
I'm running Energy Rom, and when my phone has no power, or it says it has no more power, i just take the battery out, and bam! 50% more! and when the power finishes again, i take it out and bam! some 28% more! and i do it again, and it gives me some 3% more the next time, and then nothing.

Ah the extended batterys again. (Also posted on Q&A threads.) But here is what I have been told to do when you use an extended battery
It must be an official battery, not a cheap ebay china copy (As the second battery is usualy duff)
As you are aware, when you take battery out of mobile and put it back, its still showing a greater charge. (You see the power has gone up.) OK here is waht we do.
Run down the batt to 15%, take out and put in mobile again. Still greater than 15%. keep doing his until it is 10 to 15%. Now the trick here is to switch off and charge it up via the power point (Not via the computer) and you must charge the battery for at least 12hours.
It has NOT charged when the light is on green, do not be fooled by this. Remember your mobile still thinks its only one battery and not the two that the extender has.
It has only charged up to one battery, hence the green light making you think it is fully charged.
Another thing i was told was to re-flash/Re-set the rom when you first put in the now fully charged double battery.
The rom should now see that there is extra power (Mamps) so now you should find the power numbers go down a lot slower than before.
Thanks to my brother-in-law for this advice. (Steve at R&D Motorola near Basingstoke)
and the techs at Thuraya for the same problem with the extender batt on my sat phone.

Ok, I'll try to do that!
I apologize in advance if there is a similar thread; I could not find one.
My EVO has been fine, no issues. I use it heavily every day. I'm running Cyanogen 7 nightly 147 (I think) and have been for 4 or 5 days. Using the Tiamat kernel running SMARTASS.
Last night I shut down around midnight with around 50% power. I plugged in the charger but don't remember if the charging light came on then. This morning there is no charging light and the phone won't boot. Tried long holding the power button, battery pulls, pulled the SD card (for lack of anything else to try). Nothing has had any effect.
Does anyone have other ideas? I'm at a loss. If it's dead, it sure chose a strange way to go. Any advice would be very appreciated. I need this thing for work and home. Many thanks.
Just after posting I went back to playing with different chargers and power button pushes. The white HTC logo flashed for a second and the phone vibrated but it went right back off. It's the first sign of life I've seen, but I can't get it to repeat or go further.
This happened to my sisters Evo when she first got it last summer. Luckily it was the battery and HTC shipped a new one for free. The warranty on the evo is 15 months so you can try and request a new battery!

I have found one similar thread: http://forum.xda-developers.com/showthread.php?t=913258. So maybe it is a dead battery. Been getting amazing life recently, so it seems crazy that it would suddenly be dead. Is this common?
Any suggestions for going to the Sprint store with a rooted phone? Since it's a bad battery, they may not need to look at the phone once it boots. I haven't had to do this before, so I'm not sure what to expect.
if you do go to a sprint store, i would not let them keep the phone or even take it out of your sight. if that happens you may well find yourself unrooted. but thats just a guess. you can get on ebay or any other similar site and buy a cheap battery for less than $5. then if thats not the problem go from there. this same problem happened to me but luckily one of my friends also has an EVO so i just used his battery and my phone worked great. so i just bought a new battery
Thanks for the input. Headed to the Sprint store in a minute to see if a battery will solve it.
It was the battery. They tested in at the Sprint store and pronounced it DOA. They said they don't normally have spare batteries but they happened to have one, luckily. I was pretty grabby with the phone and didn't let it go for long. Once it started to boot I took it back and they never saw the Cyanogen screens.
Overall they handled it very well. I was impressed with how responsive they were. I was out of there in 10 minutes.
