Hey, my time and date changes back everytime i take out the Battery. Now i wonder if there is aproblem with the internal Battery and if there is any and how I can replace it? I already Formatted the Firmware again, did not help always changes back to some 2006 date 12:00.
What is happening there?
could it be that the OVerclocking did that to my internal Battery?
I run the BatteryStatus Plugin on 260 MHZ
Thanks
The prophet has no internal battery as far as I know... Being a WM5 device there's no chance of data loss if the main battery drain out so no need for the internal battery to keep data safe on the device as it was for the WM2003 devices... Think this is the correct explanation on why it doesn't have one...
Then why does my Time reset everytime i take the battery out. Is that a hardware problem?? whats the deal???
I told you... it doesn't have an internal battery...
Allright man, dont get pissed I just want to Know why my time is being reset everytime i take out the battery, should i send it in??
please answer
WM5 devices DO have a internal battery. It is not as big as massive as those in WM2003's version where it needs to keey the memory runnning to keep the data. The one in WM5 devices are probably all tablet little battery. AFAI can remember, there are cases of Wizard forgetting the time/date too and an investigation has been launched to search for the internal battery.
UPDATE: Read this for Wizard
http://forum.xda-developers.com/showthread.php?t=279384&highlight=internal+battery+wizard
it has an internall backup (small) battery, although it is actually a capacitor that acts as a batter. I presume the Prophet has one too. BTW, as the thread mentioned, you can get this problem fixed if you were to charge your phone directly (rather than charging the battery). Read the thread for more info.

YES IT DOES HAVE AN INTERNAL BATTERY.
The Prophet (and all WM5 PPC) does have an internal battery (very small but not a capacitor) for not forgetting the time/date when you take out the main battery.
exxi, your Prophet's internal battery is probably dead.
I have the same problem.
Could be the result of a too high o/c attempt, or the vodka that went into my phone.... who knows ?
I'll send it back on warranty soon, I hope I'll get a working backup battery afterwards ^^
thanks for the responses guys, I really appreciate it, i have the feeling that the o/c did this to my internal battery, I hope nothing else is damaged. I am going to send it in soon, lets see what happens.
Thanks guys!!
Since a lot of users are having that trouble, there's much chances our devices have faulty batteries. For (main) battery switching, if you're fast enough, you can switch them in about 2s, and won't lost date & time. If you're not, well, practice

I'd guessed that not many will discover this 'flaw' unless they swap battery/sim frequently .. as like me, I'm not sure if I have the problem or not.

If you like capital letters, YES IT IS A CAPACITOR (well, at least I'm sure for the Wizard and unlikely HTC will be using different technology on different devices). Attached the screen shot of the service manual of the Wizard. Note the picture and the word "Golden cap replacement", which actually called 'Gold capacitor', is a capacitor, which acts like battery. Read this for more info.
http://www.ttiinc.com/object/FP_pan_goldcap.html
Electric Double Layered Capacitors, known as “Gold Capacitors”, offer the highest volumetric efficiency of all capacitor technologies. It is often compared to a secondary battery. Unlike batteries, the Gold Capacitor does not rely on a chemical reaction to produce electric current rather it is a storage cell that utilizes the absorption/release reaction of ions.
Gold Capacitor has no limit to the number of charge and discharge cycles it can sustain, and does not need a charging circuit. Repeated rapid charge and discharge cycles are also acceptable.

Also note that, it said it needs to be soldered to have it removed. You don't usually solder in a battery, the heat from the soldering will probably damage the battery of that size.
Anyway, having said that, capacitor can be damaged anyway. My Citizen Eco-Drive watch, which uses a cap to store energy, went to the 'hospital' for a change of a faulty capacitor that won't store charges for more than a day (which specification said it will store up to 3 months).

You may be right, but you can't tell that's not the o/c fault just because it didn't happen on your device, that's not logic at all.

I am probably wrong abut it an actual bateery, as you said it is a capacitor', but that is not the issue.
the issue is all WM5 devices (not only Prophet and wizard that by the way have exactly the same internal battery / CAP) does have some kind of an internal battery , that keep the date and time for a few minutes, when the main battery is taken out.
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 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
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.

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 have samsung galaxy s2 just over a month or so and i have big problems, due to battery. I know this is common issue on this device.
Until now i try to recalibrate battery like that, no hard reset. The phone it;s new and it had ICS 4.04 installed on the first place.
1) drain all of your battery untill phone shuts down
2) turn on and drain battery until phone shuts down ( repeat until you are unable to turn the phone on- this step is very important because we need to drain the battery competely)
3) take the battery out and wait 5 seconds or so and put it back in
4) Charge the battery while the phone is off
5) when the charge is 100%, take the charger off then charge again to get 100% again
6) turn on your phone and enjoy your new battery
Once i try to take the battery out after charge, and wait over 2 minutes. I know this is a common issue of s2, but i have some screens, maby someone had similar problem.
----------
-------------
Next, i'll try Battery Calibration (can't post the link, new user) tool from the market / wait for Jelly Bean official update. Then hard reset. Next step: service.

The batteries in these phones can't be calibrated per se. Just use it normally for a bit. The peaks and troughs in your battery graph are because you're clearing the fuel gauge data. Mine would drop from the 73% I'm on now, to about 14% if I cleared the fuel gauge chip data, until it relearnt its settings. Just charge normally and use it for a few days, it will sort itself out.
If not, new battery.

Im having the same problem. Tried swapping batteries with another S2, recalibrating the battery and even installed another rom, same problem persists. The phone will auto switch off after a few hours of not using (overnight especially), and batter will drain like mad when it happens. Brought the phone back to samsung for repair now.
Same here...

I'm currently having the same (really annoying) problem. My international GS2 is less than a month old and uses the latest official firmware on ICS. It happens almost daily -- or should I say nightly? The phone has at least 60-70% of battery left by the time a go to sleep. When I wake up in the morning, it's completely depleted. My stats look exactly as in the screen-shots in the first post. I'm always charging/using it "normally" but it hasn't sorted itself out.
I don't really know how to solve this and it's frustrating. The Internet has mixed "feelings" about the solution(s)... However, same as with my battery issue, I'm looking for something more stable and reliable.
Am I missing something? Does anyone know the exact cause and how to fix it?
Hello, I took the phone to a local service (pointed by Samsung from my country) and they replaced my motherboard and another pice of hardware....something in the recharging sistem, i dont know details. I think there is a "lot' of bad motherboards... people form the service call it a generic name.
In conclusion, the problem was the motherboard, not battery. I have recovered the device from service one day ago, if i'll experience any problems... i'll get back with details.
Cheers
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
