Universal suddenly shuts down; battery or other problem?

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

Extended batt! Please reaD!

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.

oh well, at least it actually does last more than the original one.

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.

Best Battery for HTC HD2?

I bought my HD2 used and the battery doesn't really get me through the whole school day, (8-4:30ish) even if I don't really do anything on it, it drains pretty quickly. I've conditioned it and everything, but I think the best things to do would be to buy a new battery.
I'd like to buy from eBay or a reputable online retailer.
Does anyone have any great stories with any batteries?

Make sure out have the apps Juice Defender Pro, Screebl, and SetCpu (with a profile to run the processor at the minimum when screen is off). With these, plus official extended battery, I get between 24 and 36 hours on my HD2.

go on ebay and there's a seller called c_cell he's got (737177) feedback,he has a 2430mah battery,NOT the extended 1 lol,same size as the origional(1300mah),i bought 1 off him a month ago,WELL IMPRESSED...................let me know how u get on

is that e_cell? for the battery not c_cell?
looking to get the same, whats the life like compared to the original?

yeh sorry,its e_cell lol,battery is around 50% better i'd say,just my opinion,it will vary cos different ppl use different roms & sd cards

There is a lot of complain on Gold battery from e_cell on xda. Anyone else get good result from this product?

so did you have a new batery now?how is it?

can somebody tell me the difference between e_cell and c_cell battery? give me some advice because i need a new one...thanks !

I use Typhoon CM7 NAND Android on my HD2 and I get easily through 2.5-3 days with moderate use (WiFi included) - my avg stand by is 2-3mA but sometimes it even goes to 1mA (rarely but it does).
You shld get rid of wm if you have it and make your HD2 worth it!!!!

I bought a battery which shoul have 1600 mAh but so big like the normal HTC battery with 1230 mAh.
I didn't feel that I had more capacity, it didin't hold longer than with the normal one.
So i bought the original HTC HD2 Power Battery with 2400mAh and it was awesome. I could easy work with the phone for 2 days without loading and i make a lot with it.
The disadvantage of the Power Battery is that its nearly twice as big as with the normal, but i love it to work with the phone without looking on the battery percentage

If want long work time and size does not matter - original with 2400mAh. And no "chinese" batteries with increased capacity.

dot bother with the ecell battery its a waste of time

I'm not doubting that that's an excellent battery, but when you got the 0mA reading you appeared to be charging the phone and 2 days isn't really that hard to manage if you only use the phone moderately. Also don't forget that the ROM itself will have some effect on the results.

you can buy several backup batteries for emergency

[Q] Battery Life

Hello Guys,
I have a new Samsung Focus, around 3 days old.. I have been given a 1650 mAH battery. The battery life is terrible, discharges like 10% in one hour with hardly any usage with Wifi OFF, Edge ON, auto brightness and all the power saver methods applied.
Should i charge it overnight or something ? Like 12 hours at a stretch or something?
Pls help

I'd take the battery out and feel it. If it's a Samsung battery, it should be perfectly flat on the sides. I was having terrible battery life, and it was because the battery had gone so bad that it was bulging.

Can you please detail your WP7 OS build, if it's an OEM Samsung battery or a generic one? It looks like you have a bad battery, same conditions as yours my one year+ OEM battery holds 3days+
There's also a specific thread for battery life I started a while ago over here

The battery is curved on the left and right sides, flat on the top and bottom. Its a SAMSUNG battery EB575152LU 1650 mAh. I am not sure if its OEM or generic
OS version : 7.10.7720.68
Should i ask the seller to send me a 1500mAh NEW battery? mayb thats causing the issues?
Or I should wait for a few charge cycles to complete?

With the infos that you just shared, it looks as the battery has gone bad.
I wasn't aware of an OEM battery 1650 mAh, see my reply here. Can you confirm it looks like that or maybe post a photo of it?
Keep in mind that cheap batteries look like those but there are significant differences, but you'd need an original battery for comparison.
Even one of my chinese cheap batteries still holds 70-80% of the regular battery... (that's 2+ days in the conditions you mentioned above)

It looks just like the one in your post, except for 1650mAh. Looks like original/OEM Samsung.. will send pics once i get home.
Morning charge was at 100% . Hardly any usage, some amount of whatsapp texting, now phone is switched off
The seller has agreed to send a replacement battery. I am just hoping that it is not a phone fault or Mango update screwed it up. Can it be a phone issue?
Checked on amazon, one guy said The battery does not hold charge, otehr said that NEAR FIELD COMMUNICATIOn should be written below Samsung, which is not the case in mine.

7720 has quite good battery life so shouldn't be a phone issue. I have 2 Focuses and both hold about the same and from what I've read so far, only a big hardware problem (like phone overheating) could cause so dramatic battery discharge. Also, weak network signal might cause faster drainage, but not at this rate. You can try switching 3G off (lowering to EDGE) and see if it makes any difference.

Hmm.. I even turned off 3G. Let me check again.
If I install any customs WP7 roms , will it make a difference.?
I 'll re check once i get the new batteries..
Thanks for your help. Appreciated

The dft/miro custom roms offer better battery life, but by a margin, don't expect miracles. Your battery should be able to hold more than a day in your conditions, and I bet that's to blame in your case.
Let us know how it goes with the new battery.

Thanks for your help.
Now, the battery life has increased quite a bit.. getting around 12 hours on a full charge using the same 1650mAh battery . new one is yet to arrive.
Heard 8107 update considerably increases the battery life? but i have ATT uncloked focus in India. If i use ChevronWP7 to unlock it , it gets relocked on zune sync right? I am confused as to "relock" here is whether Carrier relock like I cannot use my local GSM sim here? or developer relock? I am sorry, new to all this

Read my post here. Ignore any flashing, just understand the steps and what's written there (eg: Flashing, downgrading, upgrading firmware etc does not affect Network Unlock).
Basically, after you unlock with WindowsBreak project, you just need to run steps 3 and 4 there.

hi, i got a Samsung EB625152VA (OEM) battery of 1800 mAh.
But it seems the back cover doesnt fit so properly with this battery inside.
Do i need to do any modifications in order to make it fit ?

Battery Issues

I bought a used Note 4 a few days ago which I've been greatly enjoying using. However it has been behaving rather oddly.
It turned off a couple of times, and at first I thought it was random, but then I realised it was turning off at around 20% battery. It wouldn't turn back on until I plugged it in, but when I did it would tell me that I had ~20% battery left. I then realised that it wasn't letting me charge past ~80%.
I tried calibrating the battery using *#2882# (code may from memory so may be incorrect. I think I then allowed it to drain and was delighted to see that it could get to 0% normally. I attached it to the fast charger, it then quickly reached 80% and then slowly progressed past to reach 100%.
However today (the first trip into the world after the first successful 100% charge) it reached approximately 30%, died like before and then when I plugged it in it said it had 11% battery. The battery usage graph will illustrate my point.
Any ideas anyone?

Buy a new genuine battery (preferably direct from Samsung), or get an Anker or PolarCell, sounds like your battery is past its best.

Yes, but it's a used phone, so:
a) you have no idea what the battery has been through or how it has been treated
and
b) you can't be sure it's even a genuine Samsung battery, it could be one of the very convincing fake replacements.
So first thing to try is a genuine replacement battery. If it doesn't make any difference, then at least you have a new one (which will always be better) and a used spare.

But equally, I don't want to spend money on a phone I may have to send back. Though I suppose based on my current experience I certainly would want another note 4
