Before you suggest i change the battery.. it's just fine.
the problem started the day i flashed WM6 (over a month back) and has only started to bug me lately as my phone died on me 3 days in a row.
basically the moment the battery level gets down to 40-50% the phone just dies.. i could reset it and it powers up for a second or so then it dies again.
i flashed WM5 back.. and the phone was working fine even if the battery level reached 10% (i get a warning bubble but it doesn't just die on me!)
i've searched around and noticed the only suggestions were to change the battery, which seemed kinda useless as i'm almost sure the problem is somewhere in WM6 power management/battery handling.
any comments?
Try another WM6.
If you used Helmi's/Jwright's try DarkForce's/PDAVIET, or vice versa.
Mate I can get mine to die at 90% battery just by switching WIFI Bluetooth and opening a CPU intensive app (Google maps/Tom-Tom).
I’ve ordered a new battery and its coming next week so I will see if this is any better.
This is more than likely a Current problem, an in the battery cant supply enough amps for the phone to function properly, im almost certain that the WM6 ROMS do cause more current to be drawn from the battery but it is most likely that this is just highlighting that the battery is on its last legs.
Ill post back when the new one comes, If its doesn’t fix my problem I will be flashing back to the standard WM5 ROM to do some tests.
its probably the battery
i had the same problem. a new battery fixed it. it would die at 45% but now works all the way down to 5%.
new batt or borrow one from a friend to test.
I have seen the same thing on the BA fora as well: It's not that the whole batery is dead, but some of the cells in the battery are.
There it was also fixed with a new(er) battery...
I had to add a comment
I use a Exec with WM6 and i have a MDA Pro that i keep trying different roms on so i can use and mess with it and at the same time keep my sort of stable exec for work.
i do swop batteries between phones and so on, i cant say what roms i am useing when this happen but i have the same problem on the MDA Pro 40-45% it shuts off, reset and it starts for a second then shuts off, so i then put the battery from the exec ( charged ) in the MDA and away it goes my exec happly sits there at 40 or so % and will go down to 0 flat.
So its not the battery its the phone, but as said by someone else it could be dependent on what rom i am useing at the time
It is the battery..100%...pls buy a new one or try exchange from yr friend..nothing wrong with the Phone..
I tested every wm5 and wm6 roms and i have two batteries: one dies at 35% while the other never dies but gives warnings on the red side.

I still think the main problem is the battery.
But I think WM6 just uses more power intensively then WM5 does. That would be the reason the phone dies.
Mine always goes back on again but then dies booting the OS.
Had the same problem with old PDAVIET rom
Hi, had the same problem with the old PDAVIET ROM 2.08 somethign or other, but since upgrading to 2.10.02, everything is back to normal, and lightning fast.
Try the newer ROM, and then see if the same happens, and if it does, then it is the battery which is definately causing the problem.

I have read somewhere in these forums that when the Networks release their official ROMs for upgrades they all clearly state that you should ensure your battery is at 100% charge as when you run the ROM upgrade the battery management resets its self to the level of the battery.........ie it assumes 100% but if your battery is at only 50%, then 50% becomes what it believes to be 100% therefore half the battery life.
I have to kind of agree with this because my first WM6 upgrade I was so eager to do my M5000 had only been on charge for 10mins or so and after the upgrade battery life was awful, however since then I upgrade only after my M5000 has been at 100% for about 30mins and since have not had any issues wahtsoever with battery life
Hope this helps

I thought it was because when you put your device into BL and flash it to a new rom, during the upgrade the phone won't charge.
So if you update with only 10% battery the device could turn off during the flash, and that would be a bad thing.
So they state (advice) to charge it to 100% before flashing.

Wrong. The previous poster is 100% correct. Better charge your battery to 100% before flashing.
What should I do if I had ROMed my Uni not in 100% bat.?
Your PDA needs to be fully charged because during the flashing the battery is not charging. So if your phone runs out of battery before the upload has finished you are screwed.
I never believe that the state of the battery is been used as the 100% level of your battery during flashing. I make elektronics myself, the battery level is always measured elektronically.
I had the same issue. I fix it with a new battery and works fine since then.
A bit of both
WM6 does use more current compared to WM5 and most of us have been torturing our Uni's with all the flashing we do (We don't use them as a phone much more of an intellectual playfield) . Also most of us have had the Uni for a year and some longer. My XDA Exec is 2 years and T-Mobile MDA Pro a year in sometime. The batteries are a bit older and unable to supply the increased power as before. I do have this problem if I use the older batt on WM6 and the newer batt works just fine. But then again the older batt works fine on the MDA pro (unchanged with original MDA Roms).
Cheers
Battery
Hi,
i was suffering from the same batery issue in the last 10-12 months, and let me share my experinces. After my original battery started to die first at 20% and finally at 50% i bought a new one. I read tonns of articles about LI-POLymer batteries and tried o follow as it was written. The result : after 4 months my new battery is in the same state. I bought 2 other. When i started to use the first, i had always recharge it between 10-20%. Now this battery dies at 12-15%. I let my latest battery to go down to 3 % ALWAYS and after 5 months NO PROBLEM AT ALL!.
So my experience:
-let the bttery go down. I don't care what other experts say about the characteristic of Li-Polymer. For me it seems that practice is different.
-NEVER,NEVER,NEVER cahrge the battery if it is not empty. In my car if I want to use my UNI for listening music or GPS then i REPLACE MY GOOD BATTERY with the old one, and then i use the car charger. With my laptop i use only BLUETOOTH connections
-ALWAYS USE original charger. No laptop, no car charging
-If i do an upgrade for any ROM i ALWAYS DO THE UPGRADE WITH THE OLD BATTERY.
-USE at least 2 batteries, one is always charged fully, and if the other goes down you can replace it quickly
I am sure that there are many experts, who can tell me why i am wrong, but the pratice seems to work for me. And i have not found any experts who could explain these strange situations with UNI. Now I have 3 batteries. All is about 10 months old. One dies between 30-50%, the other dies always at 10-12% and the last always at 2-3%.
crikey, the device is big enough as it is without carrying around more batterys. Mine's starting to die at 70% now. When it reboots it seems to die when the radio stack is activated. Had it for 13 months now my stylus falls out too had to put cellotape around it which has sorted it.
Just waiting for three(uk) to bring out the tytn so i can move over with their x-series stuff!!! woohooo!
I've had mine about 13 months now and it started dying at 40% left then 60% then 85% (of battery left!). I bought a new battery and 3 days later without charging it's still on 65% left
Thought I would create this to see if you're happy with the battery life on your Vox and post some tips about charging and discharging for better life.
I am generally dis-satisfied with battery life on the Vox however I keep a fully charged battery in my Jeep, one in my wallet and one in my Vox to always stay connected. I switch to my 2250mAh when I know I'm doing to be using WiFi a lot.
Anyways, here is what I have found;
If you reboot your phone while charging, it will jump to a higher charged state and not properly store the charge. To combat this, I have placed a strip of electrical tape over the 2nd connector to the left on the battery which stops the battery from reporting the proper charge level. I run it down and place it on my external charger. Charges last a lot longer after I do this.
Any tips for how you use your Vox to maximize battery life?
I am happy, because I usually get through one day without any problems and then I am plugging it in over night anyway! I'd love a battery with higher capacity, but I hate those extended covers!
I'm happy with the battery life.
I find it lasts longer if I use the phone until the battery is pretty much dead and then charged until full again.
I usually get 3-4 days out of it that way.

I am not happy at all. 3-4 days ? I bought vox few days back and I get 2 days max, with most of time on standby.
Okay so I received my 2250mAh battery cover, finally. However when using the battery, my device shuts off randomly, this only happens with the extended battery. It also seems the contact sheets are deeper and the pins have a hard time reaching them. If I slide the Vox shut hard, it will also reboot.
Any idea's?
The battery life is fine as long as you don't OC it. I manage to get 3 days with normal use.
With the CPU up to 240Mhz, it barely lasts a day. So i rather use the original 6.0 rom without OC and its still fast. WM6.1 is to slow without OC'ing for me.
So after 6 months of use i finaly found my settings wich i like. And makes the battery life OK for me

I got this too when I just received the battery, but after something like 2 weeks these problems disappeared
I'm happy with battery life...
I get up to 2 days with heavy voice, email, and text -- some bluetooth, very little WiFi or Internet. Personally, I've never had a problem with a phone as long as I get a full day and can charge at night. Even if I got 6 days on a battery, I don't want to have to remember to plug my phone in at some point during the day when the battery is about to go. Much easier to plug in every night.
Battery life is exceptional!
I was having problems with my original battery; the phone would simply power down even though it showed that it was charged; and did not have long battery life.
I bought a new battery now I get 3 even 4 days of use with some Bluetooth and WiFi use (not much though). The new battery also seems to have solved my power down problem; had it for 4 weeks, not one power down. I am using the LeFab VoxRomWM6.1XIP20202_v1.0. Quite fast on it's own; I do not over clock.
Hi people. I'm having battery problems since I bought my TP. I tried many ROM and Radios combinations and the problem persists.
Also tried discharging the battery and long charging while turned off (3 consecutive days) as recommended by some members here in xda.
Nothing solved. What could it be? A hardware problem (TP itself) or only a bad battery? Whats more likely?
I would like to know where can I buy an original spare battery to test this. Anyone know?
Thanks in advance!
google.... Here's one, but it's a yahoo page. Take down the oem # and start from there. Also, i think there was a little booklet that should have came with your tp about accessories... http://www.wirelessground.com/htctprooembatt.html
what about using non-official batteries? its risky? because there are batteries for TP for about 5 usd
You know that it will drain battery as long as it is in "sleep-mode" and not entirely powered down. You have to press the powerbutton for 3-4 seconds and then it asks you if you want to power off.

Of course, I mean my TP has a abnormal batt drain with normal use... the batt lasts less than 12h. I unplug it 10am and the battery is finished before 10pm depending on use.
have you by any change changed the TF3D theme?
i made my own theme, but i get the impression that battery drains much faster now. watched the battery fall from 21% to 18% in 3 minutes without doing anything besidesscrolling between TF3D tabs.i think themes might be making more use of the 3d accelerator and drain the battery..
I'm using default theme from ROMeOS v1.20

Oh, I´m sorry
Do you have it turned on all the time in locked mode? Or do you put it to sleep/standby when you not use it?

Standby when not in use. Actually, while I dont use, the battery drain seems normal, maybe 2 days or more. The problem is when I use it.

How about upgrading the Radio Rom!? I have found since going to 1.02.25.28 and having ROMeOS² v1.21 my battery life is much better than stock Roms of both!!
Its something worth trying and easy enough to change back...
Has there been any good solutions? My battery life is starting to annoy me.
Maybe I'll pick up a second battery and charging cradle thing for it...
That's one thing that I liked about the instinct...
I think we need a Stock TP to compare it to .. I know when I bought mine for the first day or two without adding anything to it, I didn't notice an issue with the battery. Now that I've installed tweaking software, theme, etc - battery drain is definitely noticeable. I'm thinking it may have to do with one (or more) of the programs we put on the phone.
Anyone here have a completely stock TP with a battery problem?

tried all radios available in wiki page (except .11 and .16)
but that was with romeos 1.12 and dcs, I'll give a try for .28 with romeos 1.21
but I'm pretty sure that the problem is hardware, since many people use romeos 1.21 and radio .19 and dont have problems...
My phone had a very short battery life when it was bone stock too.
I'm afraid to see what it's like now with the tweaks!!!
mine is original stock TP batterry..but also facing the same problem. in average have to charge twice in a day..and the charging takes a few hours. so my phone is only running on battery for not more that 15 hrs in a day..
I'm hoping now thats its a bad batch of batteries problem and not a phone itself problem
I'm having a simlar issues. Put my TP on off/standby (single press of power button) at around 10pm, on flight mode enabled, all appliactions closed via task manger. Battery was at 80% when I did this. My TP's low battery alert woke me up at 4:30am at 8% charge.
My Blueangel used to last several days in the same state out of it's cradle without needing to be charged!
I to am hoping it's just a duff battery.
UPDATE: Seems I was being a twonk! I had unchecked the Auto-Shutdown option for a game I was playing and forgot to turn it back on, so my TP was turning on at midnight to do it's housekeeping and not shutting down again properly.
I still don't think my battery life is normal though, may try the following:

Found this on Sprintusers.com: It's an 06 post, but I wonder if it's still an issue. Found here http://www.sprintusers.com/forum/showthread.php?t=175896
Received the below from my Sprint rep.
It has been brought to my attention that there is a glitch in Windows Mobile phones that has been there since WM5… Apparently when a phone is first used the firmware looks at the charge on the battery as a reference point as to how long to charge it for until it is completely charged. So for example, if you have a WM phone that has a half charge on the battery when you first plug it in the device will only ever charge up 50% of the battery. You need to basically set the phone to put that marker in place when the phone is completely dead to gain the most battery performance you can.
Here is the best practice for doing this:
----------------------------------------------------------
1. Let the phone completely die on battery power.
2. Plug the phone in and charge for only about 5 minutes (just long enough it can boot up completely)
3. Perform a hard reset of the device, this is done differently depending on the phone model.
4. Then place the phone on charge for at least 8hrs.
---------------------------------------------------------
This should reset that marker that the operating system places on the battery charge cycle and will allow the phone to completely charge the battery rather than only a % of a full charge. This procedure can be done at anytime and I would suggest having your customers try this process first before returning a device based on battery life issues.

My apologies if I am here with the same complaint, but I tried searching this forum and found nothing that works for me.
Basically, I rooted and flashed CM 5.0.8 and I have been having battery issues. Now its not that my device is draining battery at a very fast rate (seems it is indeed doing that), but I suspect there is some problem with the battery meter.
So from all the stuff that I read, I decided to recalibrate the battery. I charged it up to full, until the green light went off, until the status showed 100%(full) and then some more. I then restarted into recovery(Amon-RA 1.7.0) and wiped the battery stats and rebooted back into CM, while having the charger connected at all times. Its worth noting however that during the time the phone was booting itself into recovery or into the ROM itself, the charging indicator stayed off. Thanks to that, when the phone booted into CM, the indicator was red for a few mins before it turned green (charge had dropped 99%)
Now I've done this 2-3 times, including letting the phone die due to an empty battery, but I am still getting very little life from the phone. For the record, I have the end button set to sleep and I don't have any continuously running widgets and my syncing apps (twitter) are set to sync only every 1 hour.
Anyway, again I don't think these apps are draining much battery, since once the battery dies down and the phone switches off (after light to moderate usage as compared to the life 1.6 Donut gave me), when I put it back to charge and turn the phone on after 5-10 mins of charge (while the phone is off), the meter shows a charge level of around 65%. So I suspect that the battery charge is at around 50-60% during when the meter reads it as around 1% and forces the phone to turn off.
I also tried switching on the phone after it had turned off, but it switches off immediately after booting (at least on 1.6, I could reboot it a couple of time on a 'dead' battery)
Are there any other tips that I can use to recalib my battery? Any idea will be much appreciated as my phone dies out each day before I can get back home and put it on the plug. Should I consider upgrading to CM6-RC1? Has it been proven that the battery performance is better on that?
Have u tried swapping out the battery with another one to isolate it to possibly the battery itself? Isolation is key, that way could it be ur extusb isn't charging correctly or is it the battery?
Well, I do have a spare - the one I saved from my bricked G1, but I haven't tried it out yet. The battery was working perfectly well just a few days ago when I had a stock Donut. So, I suppose it isn't a battery problem, but no harm in trying out the other one.
i had issues with my lithion battery and found out it happened to be on its last breathe. And with my spare i had it worked good. did u drop the battery at all? with lithium ion batteries can be as delicate as expensive china or porcelain. And to be honest the batteries that came with our g1's aren't really that good. If you can I would suggest getting an ext. battery from ebay. ive heard that fully discharging a lithion battery isn't the best practice either. I'm no expert just experience Best of Luck!

reading the Cyanogen 5 thread I noticed at least 5 people with a broken battery...
for the record mine is broken too...
it's all swollen up... I mean, I can use it but it doesn't last a full day and it doesn't fit perfectly anymore in its slot inside the phone...
I'm starting to think that maybe for some reason flashing cyanogen 5 caused this issue, since so many people had this problem at the same time...
or maybe it's just a time defect of some stock htc batteries... who knows...
@GigiSpligi: Nono... don't blame CM for the swollen battery. Batteries tend to swell up after a lot of usage (charge discharge cycles). The battery on my old Nokia phone had swollen up after about 2 years of use. Similarly my friends E51 battery. Also my G1 batt seems to have swollen a little bit already. So nothing to do with the ROM.
Of course, if the ROM is making you charge frequently, then it is indirectly causing the effect on the battery.

The exact same thing happened to me ... actually on all ROMs now ... i'm gonna look into getting a new battery and sdcard which kinda sucks, but oh well. when i think about it, i wasn't have any problems till i started flashing sense based ROMs, especially Slide ROMs. so i must have done something wrong. i can't even make a phone call for longer than 10 mins before the phone shuts off and have to plug it back it into a charger just to get it to boot to the home screen
... hope there is a solution ... haven't read through this thread yet. just wanted to let you know you weren't the only one with the exact same problems

hahaaha well that didn't take long to read ... yeah my battery is somewhat swollen and i did drop the phone once ... time for a new battery i guess ... sucks
[x-posted from Cyanogenmod forums]
Ah well... gonna have to pull out a new battery and see if that helps in anyway. I will have a look at the device usage stats to see if anything is causing unnecessary drain. Since there has been a drastic change in the battery life after the upgrade, I do not want to blame the battery itself yet. Guess some app is driving the phone nuts.
Ok, I was just seeing the battery usage history in spare parts and I there are some interesting usage stats there.
Network usage - While Market, Android System, Google, Calendar are around 1% - .5%, almost 100% of the usage has come from Media. I think this has been trying to keep the network alive throughout the time. I dunno if network means Data or just the voice network. The packages listed under Media are Camera(twice), DRM, Download Manager, Media Storage. Is there any reported issues with Camera or Media Player?
Also, Spare Parts says my Battery Health is Good. Is this a reliable indicator of the battery life?
I believe spare parts receives the battery info via "Testing" which comes stock on android. Let me know how the new battery works out cuz I want to research further when it comes to phone environment versus the actual battery itself.
I have same problem with my battery. I guess maybe battery life since it already use 1 half year. Anyway, who knows.
new battery
just picked up a brand new battery today. gonna leave it charging overnight. will report later on whether it fixes the problem with the random shutdowns
... on a side note, i think there has been a battery issue since CM5 correct? in my sig there is a recalibration method by xda member 'my_former_self' for those who have not read it and if your battery is still good to go ... worth a try
new battery
so it turns out my battery issues was in fact the battery. the new battery is working awesome. phone hasn't randomly shutoff on me all day with heavy texting, some youtube vids, mild internet browsing, and several apps ... 17+ hours later about 2% charge remaining. gonna run the battery through its conditioning cycle.
fyi i turned airplane mode on when i was in class ... approximately 2 hours
New battery it is
After spending over 4-5 days with the battery, I pulled out the spare that I had (with a couple weeks of usage) and installed that on my phone. Just to be safe, I drained the battery after some initial charging and ran it through this battery recalib method.
I did this yesterday morning after it being charged fully. I also installed SetCPU after recalibrating. Its run 2 full days of regular usage and I still have over 50% charge left. Ain't that cool or what? I think I will leave it uncharged tonight also and I guess it should last the whole of tomorrow as well. I don't think even the stock cupcake or donut lasted this long on a single charge. So in that case CM 5.0.8 has actually managed to up the battery life a lot (with SetCPU and, sleep on end).
Exactly how long does your battery last? It's no secret that CM5 (and any Eclair ROM) is just plain poor on battery life in these devices, even on my in-warranty Magic it chews through the battery about 25% faster than any Donut ROM such as Dwang, SuperD or CM4.
Seido sell extended batteries which fit in the original phone housing (unlike those ridiculous ones on eBay which have an extended back and turn your phone into a 2001-era brick), they seem to get good reviews, maybe give one of them a go.

Co-sign. I'm using one of their batteries and they work well.
Hey all,
I am currently running CM9 (bhundven's 7-29 herring build) on my Galaxy S 4G, and I am having some problems with random shutdown. This has only been happening for the past few days or so (EDIT: and I have been running CM9 for about three months with no issues). It seems that the phone works perfectly fine until the charge gets to about 60% starting from a full charge, and then the phone randomly shuts off. The phone will not start back up unless I have it plugged into the wall, and the results are a little unpredictable. The first time it happened, I turned it back on and it said the battery was at 1% and charging. Now, after clearing the battery stats, it reboots to 60% battery. It seems to work perfectly fine after that, and yesterday it went all the way down to about 12% before I started charging it again. It just happened again today, and when I turned it back on it said it was at about 60%.
My charging habits are pretty bad for Li-Ion batteries; I tend to let the charge drop all the way to about 10% or 5% before I plug it in and charge it all night, way past what is necessary to get to 100%.
The battery does look a tad swollen, but I might be exaggerating.
I just wanted to know if this is a bad battery with 100% certainty, or could it be a problem with the OS or internal parts, etc. I can easily buy another battery online, and I probably will.
EDIT: Also, I have had some overheating issues with this phone, and I can often smell electrical smoke in the charger port area behind the speaker, which is why I say it might be an internal parts issue.
Thanks everyone,

You need a new battery. I was having the same issue lime 3 months ago; phone was dying at half charge the when it rebooted, battery would be dead. Then when I plugged it in, it would charge in 20 minutes and the repeat the cycle. Put the battery on a table to see if its still flat. If it rocks or spins excessively, its usually an indicator of a bad cell.
Mine JUST started doing the exact same thing last week. Battery is definitely swollen. I replaced it just this evening and I'm in the process of doing a full charge from 0->100 to see how things go. I'm 99.999% sure the battery was dead. Replace yours.
Sorry for the thread necro, but I wanted to thank the OP for asking this question and to the helpful replies. We just had a heat wave here and maybe coincidentally to that, I've been having random shutdown problems. Having looked at this thread and my battery, I can tell that I definitely need to replace that. So thanks, all!
