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
Hi, I am using Cyanogen's v4.1.999 and noticing a weird behavior on my G1. I charge my phone and it says its charged. Then after some hours if I try to do some stuff like browsing or downloading/installing software it just turns off from nowhere, and when I bring it on again the battery is under 15% and I got the dialog to connect my charger. The problem is that its like my battery meter is nuts, or my battery, or my rom.
Has anyone seen anything like it?

Not the ROM definitely a hardware issue. Also try to put questions like this in the Q&A, some people get pretty touchy about questions in the Dev forum.
For sure 100% it's a hardware issue

I had the same problem with my G1 i will charge my phone all night and it will only show battery is charge 5% so what i did is went to T-Mobile got a new batt that was $39.99 and a wall charger that was $19.99 and took it home and charge it for 48hrs and i sill got the same 5% batt charge so i call HTC and told them my problem with my G1 and they told me it was a hardware issue they ask to send them my G1 and they will give me a replace for free
i got it with in 7days !! then i was happy
Has anyone tried buying a non official battery for their MS2 and care to comment or recommend any? Im going on holiday to france and i know my phone wont last a whole day without charging, so I was thinking of buying a second battery.
I read in another forum that using a non-Motorola battery displays some kind of warning. I'd go with an original battery.

using a non-original battery could have detrimental effects on your phone. there was a discussion on this on the forum of another phone. using a non-original battery could lead to leaks and other problems which would eventually lead to the warranty of your phone being voided.
stick with original motorola products. yes the battery might be very underpowered, but its the safest bet to ensure the longevity of ur phone
With a non original battery, the battery indicator of your phone shows a interrogation symbol. Also, it does not charge with the phone charger.
Sorry my analphabet english xD
@Motorola Milestone 2
bp7x 2300mAh battery
I 'm using a non-original battery . The MOMAX and everything's good ,it feels just like the original one except for battery tempperature sensor. the temp is always 26 in celsius
I personally have used seidio for my milestone and it works like a charm, its the extended 2800mah one it really performs like it should and not like how a lot of people claim thats its way less than stock! It does not always read it correctly but a quick reboot fixes that, like 50% after reboot would usually be about 70-80%. They way i used to use my phone (light to moderate level) would last about 2-3 days but after the extended I got twice that and some more. Just make sure you get stuff from the original manufactures either way and don't go for deals at amazon or whatnot as those guys might be selling either defected or not proprely stored stuff. Batteries are critical components don't go cheap on them! And no, my phone has not been messed up or had any leaks or anything and I have this for about 3-4 months now. The original battery degraded in about 6months if you have to compare.
That sounds promising, does the battery need to be charged with an external charger? And does the milestone complain that you are not using the official bettery

reebooting your phone to get the exact picture also works on the standard battery. my question is, does the back part which houses the battery heat up when used? does the phone get hot during charging? do you need a new battery cover for it? and besides the longer usability, have you noticed any other performance issues on the phone?

Actually the rebooting to get the exact picture is not the same here, a jump to 20-30% on a stock battery? I don't think so. No I never encountered any odd behavior with the other battery. No getting extra hot during charge or use, get the typical little bit of heat while using 3G and browsing like mad but that would happen on the stock battery too. Battery cover for a 2800? of course, that stuff is huge! its protrudes like mad! a quick heads up though, the extended battery for the milestone 1 and 2 can use the same extended batteries. Don't know about the droid x though. Anyways, no performance issues, no heat while charging. The back covers supplied by these after market guys are not the best quality though so if you are someone who loves dropping phones and what not would recommed getting a spare back cover from the guys you get the batts from.

No, I use my original charger and no complains or warnings by the phone. Not on the milestone 1 at least. In fact some times i use my ipod's adapter so no big issue. And it charges at the same pace as the stock, additional 1 hour or whatever. restart the phone to getting a proper reading as it shows 100% but upon restart its 70-80% since only the stock level is charged. I hear this app called battery left does great for calibration.
ALSO a thing to note, I only know of Seidio and Mugen to be relialbe after market battery guys hence their hefty pricing at times. The others claiming to have bigger batteries have cheated people with stickers and what not and usually end up underperforming and degrading considerably faster than burning paper! I remember 1USD batteries for nokias back in the day good for a quick one time run i suppose but these 1USD guys are now selling them with a better branding for like 20-40 USD.
Anyways Sedio and Mugen have facebook profiles and keep people posted on the latest on devices usually there, although its kind of sad since seidio have not followed through promised products at times.

thanks for the info mate. ill do a lil more research and probably check it out myself.
Thanks for the info i have bought a Seidio Innocell Extended Life for Motorola milestone 2 from mobilefun £30.49 its the 1500mah version same size as original battery so no extra cover is required.

Cool but as I suggested try and get them off the manufactures themselves as I have noticed some people complaining when purchased via 3rd party retailers.
Also another bud of mine had picked up one for the Nexus one, that phones back cover is a full one unlike the moto's and he too can vouch for the products positive performance. Either ways also check out some reviews from amazon.com for peace of mind.

No complaints from the phone about it being the incorrect battery the battery has been charged within/by the phone no external charger required. I got the 1500mah version from mobilefun I doubt it will give much more performance but will see.

Wifi was on most of the time, I was using my phone for the usual things. Occasionally checking socialfeeds, engadget, xda every hour or so and internet browsing I played 10 minutes of angry bids. Updated some apps and downloaded a few new ones.
Overall not a significant increase in battery life maybe an hour or so more from what I am used to.

Been running Clean GB BML rom (latest version) since it came out and haven't had any problems. Battery has been decent (not grand but not bad), and its been pretty snappy.
All of a sudden this morning i take my phone off the charger, as I do every day, and the battery meter is basically just counting down and draining. The phone lasts about 2 hours and its practically dead. I charge it up at work and again the battery is draining like crazy. I popped the battery out and cleared battery stats, no luck at all. Battery is smoking hot too.
So in an effort to hold on to juice, i fire up juice defender. This of course helps some, but still draining. And then it starts getting VERY laggy. A text comes in and the screen won't rotate for 10 seconds after popping out the keyboard and things like that.
I haven't installed any new apps in the last few days. I really haven't done anything unusual or different than I normally do.
Any ideas what might be wrong? Battery gone bad over night? Phone is actually dying?
I'd rather not have to flash a new rom, but of course if i have to i will.
help! lol

I had this issue, except for me, it started to last 6 hours, then in December lasted for 2 hours, and before new years it lasted 30 mins. I went ahead and ordered an Epic Touch 4G battery and it's back to the norm of 12- 1 day battery. Do try Marcusant's advice, but if you ask ME, as surprising as it may be, batteries don't last forever and it sounds a lot like what was wrong with mine. They're made to last about a year or two. Buying a new battery won't hurt, and if its fixed with Marcusant's advice, having a spare will only help for when it does eventually die.

My crappy chinese battery that I bought on ebay a year ago is dieing on me, the phone just shuts off randomly. I don't mean shuts down from low battery, I mean literally the screen goes black and it won't turn back on until I pop in my other battery.

That use to happen to me on my bad oem after I kept trying to turn it on past the 30 mins. Also another good indicator of a battery not holding charge is if you notice its got juice, and when it "dies" on you, it claims to have none, then it magically charges in about 15 mins.

Be careful with that. They sent me these crap 1200 maH batteries. I went through 3 of them before 1 would work. I got fed up and called them and they said if I bought an OEM battery somewhere I can fax them the receipt and they will reimburse me. And they did. Got a genuine OEM from Ebay for $12.
I have an L01F, a Japanese G2. The ROM right now is CloudyG2 3.3, with the stock Cloudy kernel. My problem is that the phone seemingly doesn't charge to 100%; it usually stops at 93-98%, but unplugging it and a simple reboot immediately changes the reading to 100%. I dug around, and whenever the phone stops charging at a level below 100%, the voltage reading is at ~4200mV, which is supposed to be 100%. I've done battery calibration numerous times already, and nothing seems to work. The problem first started showing when I installed KK Dorimanx kernel when I was still using CloudyG2 2.2 (KK). I've moved on to CloudyG2 3.3 (LP) with proper wipes, but to no avail. Anyone have any idea what's going on?
EDIT: the battery voltage hovers at around 4330mV when it stops charging below 100%
Seems like battery controller problem?..
Would that mean I have to replace the battery to fix this?
I don't think that you should do that.
For example my Mac shows 99% max, and wife's older one shows 93% max.
Just an update:
I recently found out that, using the hidden menu *#*#4636#*#*, the battery hovers at around 4330mV when it stops charging below 100% (in the past it would stop charging at around 4200mV). I think that this is detrimental for the battery's longevity, and I need to fix this asap. I've tried calibrating the battery again using the appropriate steps, still no luck. Anyone have any idea? Could this be a ROM bug? Kernel?
2 questions. How old is the battery? Have you let it completely drain and recharge?

The battery is around 1.5 years old. And I have done complete discharge and (undisturbed) charge cycles multiple times now. It only gets straight to 100% if I leave it turned off while charging. Else, I would need a reboot to change the reading to 100% after it stops charging.

At that rate I'd look into a replacement battery. Litium cells build internal resistance over discharge cycles.and Given uve done full discharge/charge cycles only getting a full charge when off is a good sign.
If I remember right u said you have a LG G2. It does not have a replaceable battery it is very easy to swap. I can try and do a basic teardown video of a G2 tomorrow at work if you would like.

I would appreciate that, would be very helpful. I guess it is indeed time for a replacement battery. No rush for the teardown though, I'd still have to look for a replacement battery. Thanks!

Not a problem man. I'll dig through the boxes at work tomorrow to build a G2 and tear it down. A new battery should be pretty easy to find on eBay, swappa, or some of the various parts dealers on line for pretty cheap. That used to be one of the biggest problems with g2's aside from broken lcd's

Try draining the phone till it shuts itself off, then charge it to 100% while the phone is still off.
Boot it back up with the power cord still attached.
It should be back to 100%.
If you have the time, a normal discharge refresh is 100%>0%>100%>0%>100%. So 3 cycles.(I do this with my 3000mA LiPo batteries at 1amp and it takes like 15 hours.)
If that doesn't help, you could try to check internal resistance, if it's over 500mili-ohms, it's a bad battery.

Thanks for the tips! And nope, I haven't been able to perform a normal discharge refresh. Unfortunately, I don't have that much time to spare away from my phone. But will definitely try this if I do find the time (before getting a replacement battery, that is).
Are you getting the same results with other roms too? Try Dirty Deeds rom, if you haven't tried it yet.

Unfortunately, it's the same with other compatible roms. AFAIK only a few roms are compatible with L01F (Japanese G2), and Dirty Deeds isn't one of them.
What I haven't tried is flashing the kdz, since I don't have the time to do that, plus I don't like JB (though the stock JB gave me the best battery life by far). Thinking back, this problem might have started when I played around with the charging speed options in the KK Dorimanx kernel back when I was in CloudyG2 2.2.

Sorry it took so long to get this made. finally got a g2 to tear apart. all thats needed is a gituar pick/nails/etc, p00 Philips screwdriver
turn sound off, theres no important audio.
1 remove sim tray
2 pry up the corner and use pick to remove back cover
3 Unscrew top and bottom plastic pieces, remembering where the black screw goes
4 remove associated ribbions and peel buttons back.
5 Pry battery out, Use a little caution here since it is a lithium battery, and you are using the back of the frame and lcd as leverage.
the frame is pretty sturdy. and the battery is taped in pretty good. a little 99% alcohol can help loosen it when the corner is peeled up,
Reinstall is opposite
sorry the video is in 2 parts, and uploaded to mega

Funny thing ive recently replaced my old battery with a new original one and stiil getting 100% at 4330mv too. Haven't figured what's wrong, still searching :/
