I recently upgraded to WM6 ROM, "Jwrightmcps Crossbow ROM Update 2.02.02 WWE", and all went well.
But then at 40% battery my phone died... and this is very similar to a problem I used to had in WM5.
Can anyone tell me which WM6 ROM doesnt cause the battery problem?
For the record, I don't think either my phone or PDA is damaged. The last time I had this problem, I went back to the service center (several times I might add), and they replaced everything eventually (both PDA and Battery). Since then it has worked fine (for about 6mths+), until I flashed to the WM6 ROM.
**** man, I hope this has not damaged my device. Out of warranty already.
I had a similar problem and also initially didn't beleive it could be the battery, but guess what -- getting a new battery solved almost all problems I had including the phone dying at 40% or above. So it might be worth a try...
IT"S YOUR BATTERY
Just trust me
the battery 'dies' after like 6 to 12 months. It just goes bad in a week.
Mine went out on like 20%, then a week later on 54%
replacing it fixes it.
mine crashes over 20%.... the battery it's new
I had same problem with battery,then I buy new battery from ebay, and then the battery status was OK it goes from 100- 4% with warning and everything. But the problem was that battery last only a couple of hours, even aftzer a few days nothing change I must have charger with me all the time.
Then I search the forum and found someons solution, that works for me too.
Just charge the battery full take the cable out and put it in again a couple of times so the battery is realy full charged, the put the device in bootloader mode by pressing Power + Light + Reset, which brings up an un-backlit screen with "Serial" at the top, and "v0.XX" at the bottom. And then just put your device somewhere and dont touch it until it died that coul be the all day. Anyway next day I put the charger in and again didnt touc for all day. And my problems are gone, the battery since then last fortwo or three days if I dont use it much.
Hope that will help somebody
Dears,
i used to read about this issue in the forum again and again.....so i desided to wrote this post....everyone was claming the battery is the reason....OK do not belive this.....it is the rom.....i used the wm6 for sometime and i was facing the same problem....and when my carrier started the 3G i had to switch back to wm5.....and now my device never turns off before i get notified that my battery level is too low it about 10% of the battery....so if you do not belive me just do this test....switch back to wm5...i am using now Hilme 3.5 v1.3.1
regards
Mine dies at 35% with wm6 and wm5 and my old battery, but never dies with my new battery.
Use Radio 1.15
My battery life increased by 200% just by upgrading to this radio ROM.
same here
i m also sufrer of same problem. now after this forum i m confused
Here is the simple fact of the matter:
Batteries are EXTREMELY complicated pieces of equipment
They often give false readings because the chemical reaction that creates the electricity is easily affected by heat\age\use\etc. Also, the electronics that measure the temperature are based on the false assumption that the battery drains in a predictable way down to the same level.
Your battery draining quicker\slower and dying when it says it has charge may be because of the ROM. However, this is HIGHLY unlikely. What is most likely the cause is external factors (eg heat, number of programs running, etc) or that the battery has "died" or become unreliable.
Recommendation: Try different batteries, and remember that batteries have a chemical reaction, before posting here
I don't know... I started having problems as well just after a ROM upgrade... but it was an official ROM upgrade. I start thinking this has something to do with the upgrade process, like some setting being "wiped out" during the upgrade and the battery going "out of sync" with the device, reporting the wrong battery level...
But, more likely, this is just a psycological effect, you install the new rom and then start playing a lot with the device to find the improvements, and you begin noticing the problem for the first time!
My relatively new I-mate JasJar also started dying when the battery level reached 40% the day i flashed WM6.
i posted here, trying to explain that it was perfectly alright 2 days back, prior to WM6.. pointless to say, everyone still said it was the battery 100%
well.. i got a new battery.. and it did indeed solve the problem.
but guess what.
i flashed WM5 back, and both batteries work fine there.
not sure what the heck is going on here.. but i'm certain there are two fixes:
- flash WM5 back on.
- get a new battery and stay with WM6

I used to think like you, but now I beg to differ, my dead battery never usable under any OS.
It used to be always dead at some % starting from as low as 0 (good ones) and increase until now it is permanent dead at 100%. I have all your intermediate voltages before reaching 100%.
If your's still usable than your battery is not complete dead yet or half dead or maybe soon to be dead.
By the way, I am using helmi_c aku3.5 v1.3 (add on version) as compared to v1.3.1 (vanilla version).
One last thing, please do use big bold characters in forum, sounds like shouting. Thanks!
You cannot judge the battery is old or new by just months.
This older version of Universal battery, it counts by number of time charged I think, inserting in USB for a sync and remove would probably counted as 1 charge.
I now do not sync using those working condition battery, I change to my dead battery for sync purpose.
As I sync only contacts, now Dotfred has a tool and now I hardly use sync anymore.
By the way, there is one guy in this same forum start another thread without reading this (closest info) or all other previous threads.
People like this deserved to be flamed, but I didnt.
IMHO WM6 uses and drains the battery different then WM5
My experience is that everyone that has problems with their device dying just switched to WM6. It has nothing to do with the WM6 itself, it's just that WM6 is more 'sensitive' to a low battery output then WM5. So if you switch back to WM5 it looks like it might 'solve' your problem but in the end the battery will die, it'll just take a little bit longer before WM5 appears to have problems.
You'll postpone the problem for a little while but it's not a fix
Just my 2 cents

Mine still working very good at WM5 as i told you.....just let the battery get off and recharge it till full....now mine is working great and keep working until 10% or less
The point is that WM6 treets the battery and power in different way then WM5. First when you upgrade to wm6 and start it first time it assumes that battery is full (the instruction says that you should charge your battery before uploding new ROM). If the battery was not fully charged then you have a problem. WM6 registers the point of current while starting first time and assumes that this level represents the fully charged batteryl. Then it is programmed for consumption of power according to processor cycles, so after such and such time of use of your device it should reach certain level of power. If your battery was not charged full at the start then it will always show false percantage.
The solution is to fully charge the battery (possibly using the way described in some post above) and then reload the ROM once more.
Of cource when you buy a new battery, WM6 registers this (each battery has unic number) and creats new pattern for this battery. That is way it is so importatnt to properly charge the new battery when you load it first time.
Hope this is helpful.

I have 3 original batteries.
In principle, good battery can goes to perfect 0%.
First battery started half dead (that is phone is dead 30%) after upgrade from WM5 AKU1 to WM5 AKU2 happen to be around 6 months after I start using the phone, I thought it was the problem with WM5 AKU2 ROM. My usage pattern of this battery is that I charge anytime I wish with Power charger and also during sync. This battery is still with me now after 1 year I have encounter the problem. The dead % grow (no change of ROM) until now it is around 100%, that is phone is dead just before it goes to 99%.
Second battery was bought the same time my first battery has problem, 1 year passed. Usage pattern are, never use this battery for sync or short connections to PC USB, never charge my battery until it is 0% (always possible) or less than 5%, never upgrade ROM using this battery. Always charge to LED turns GREEN & always sync & upgrade ROM with the dead stuck at 100% battery. 1 year has gone, the second is still able to reach 0% till now with battery last average 1 to 3 days, normally 2 days & sometimes 4 days depends on usage pattern.
Third battery, claim by vendor that some electronics is modified compared to the those bought last year. Charged this battery, use a few time to check if it is an ok battery, need to do this as I have ever bought brand new dead battery last year. After confirmed it is a good battery, I continue using the second battery and third battery always carry along as backup in case I used up the second battery.
Hope my usage pattern can help some of you to have optimal use of the battery and do not let the manufacturer earn extra money due to the problem in the old version of the battery. Anyway, this original battery will be discontinued soon due to end of life of this product. Guess I will have to look forward of getting imitations when my second & third battery is gone or maybe when my phone is gone too.

Hello friends ,
It have been 2 weeks since i got my universal (o2 xda exec) , I have tried most of the WM6 roms here , but most of them dont give good battery life..
Anybody know which is the best ROM with Best battery life? or any tips how to improve the battery life?
I usually read books and rarely hear music and i have 4 apps installed and i find the battery drain fast within 3.5hours. For this reason i turned off the phone and wifi. My uni is a new one , i dont want to have the charger all the time with myself.. I go places , do please help me..
Thanks in advance
battery life is awfull and unpredictable
I have the same problem. I use the same crossbow 2.12.08 version
with update radio ( from 1.15 ) to 1.18
I have a larger battery 3200 mAh, but th ebattery life is never more than one day. Though the battery is brandnew...
Worse is that when charging sometimes it shows 100% but most of the time this drops within a few minutes ( 2-4 ) to 97%
Then after 1-2 hours it is on 60% while usage is minimal. no WLAN, no BT
Also sometimes for some reason the battery is very warm ( during loading ).
When disconnected it turns out the universal is almost empty. Tried to disconnect the battery and leave it outside for 5 minutes then back in. but nithing seems to really improve. Also without memory card the results are more or less the same. Also always I close the applications fully.
Maybe someone can tell me what are the possible reasons...? Is is the software. Does it not see the actual charge correctly? Or is there a "hidden"battery user. Read the article about leds and all that, but this is way out of that league.
Rgds
I think that your battery is no good. My battery is 2 years old, it's the original battery 1650mAh and the battery life is 2.5 hours with WiFi enabled (internet navigation via WiFi)
If you want your battery to last longer, check the wiki:

Before blaming ROMs check the device with another battery. I had the same problem too, checked several ROMs and even downgraded to WM5 and at the end it appeared that my battery simply dies, while my other battery showed far better lifetime.
You are definitely having a battery issue rather than ROM. I am using 2.1.2.08 also and can get 3 days of normal mixed use from my original 1620mah battery.
Why not try "resetting" the battery, as discussed in previous forums, I for one can testify to it's success.
Hello all i have seen those threads about battery life but i beleive i have the worst..!
My battery last from fully charged condition in about 10 minutes of reading rss news!
It is rubbish it is also this shi* after flash. . .
anyone has a nice solution? or knows why is this happening?
i am a bit afraid of bying a new battery, because this may continue.
I dont know why vox is draining so much.
Second problem is that i cant get any micro sd wo work on it...!
It is really awfull cause vox has very little flash memory...
Please Give as many advices as you can i would be really gratefull!
Friendly Akuma.
Edit: sometime it hard shut down and then gives me false baterry indicate...
I was experimenting with battery life since mine was quickly falling down from 100 to around 75-80% within 15-30 minutes without much using the phone. My observations are as under:
1) Radio 4.1.13.47 seems to be the best in terms of battery use and call quality.
2) while charging I noticed the progress bar under "Power management" menu in settings. What I found is it suddenly shot to 100% (full) from around 80-85 clearly indiacting false charge.
3) To combat this I used my vox for sometime and it quickly dropped below 80% and then I again put it to charge. This time it charged normally for say upto 90-95% and again jumped to 100%
4) I again used it to drop the charge below90% and recharged.
5) This was continued till actually the battery was charged to 100% in normal spped. The experiment took some time.
6) Now I observe that the battery is much much stable and doesn't drain quickly and behaves like a normal battery should do.
7) Regarding battery showing inflated level after hard shut down, I think this is a problem with vox (or windows mobile?) and I also suffer from this.
Anyway you can try my method for battery charging and report any improvement if you find.
many thanks i will do some testing and try this re-charging method and i'll post my results!
One more thing I observed - Operamini 4.1/4.2beta consumes huge power - almost 1% gone every 2-3 minutes. Better if ucweb is used. I have just downloaded ucweb 6.1 for smartphones (English ver) and testing. Hope Ucweb will help to conserve battery better.
If you wish to test, link below.
http://forum.ucweb.com/viewthread.php?tid=226&extra=page=1
and some other things are that if you have windiows update automatic it runs as a process and using your ram.
i found out that rss is too
anyway you can check out your processes and some disable automatic update for them to stop running.
i hard reset and it got better i will do some further testing with you battery trick.
Don't try Ucweb for smartphone. The device is freezing.
Hello, i'm a newbie to xda developers... I had some problems with my Sensation... I am really a newb to those stuff since i never rooted a phone... The problem with my phone is that the battery doesn't slowly drain... I let it to charge for like 5 hours to get to full 100% and then from 100% it goes to 60% in like 10-20 minutes while i use it ... Other times the battery shows to have more power and other times it straightly goes to 40% from 100%... It drains so quickly i can't even go outside with my phone since its battery gets empty... Sometimes, even if the phone is 60% it randomly shuts down and have to restart it for like 5 times to get it work for at least 10 minutes. Might it be the battery? I tried going to recovery mode but i get the red triangle with an exclamation sign in it... Any reply is appreciated, thanks!
Maybe your battery is rubbish and you should just buy another one.
Although is one thing you should try first, recalibrate your battery.
What all these methods amount to is how to teach your phone about battery performance. Calibration is about enabling your phone to provide accurate estimates of remaining battery charge and will not, in and of itself extend the usage you get on a single charge (though it may possibly prevent the phone going into power save modes prematurely, wrongly believing the battery to be lower on power than it is).
The phone stores information about the battery in a file called batterystats.bin which sits in /data/system. Normally you won't have direct access to that file, but you could find it with an app such as root explorer, which allows complete access to the phone's file system.
When you install a new ROM, or a new battery, or perhaps periodically as the battery ages and performs differently, you need to get a new set of battery performance statistics.
By charging the phone to 100% you are starting at the known maximum for the battery. At this point, the batterystats.bin file needs to be deleted, which forces the phone to recreate the file from scratch, using the information it is about to collect. It doesn't matter what method you use, battery calibration app, or from within recovery - they all do the same thing and delete this file.
The phone is then allowed to drain fully. This gives the other end of the scale, the known minimum. The phone then has then experienced the full charge/discharge cycle of the battery and stored that performance information in a new version of the batterystats.bin file.
Now that the information has been saved, the phone will (hopefully) be able to provide accurate estimates of the battery charge level, regardless of how much of the battery charge you use before reconnecting the charger.
If you don't have root access you can download an app from the market called "Battery Calibration". It does the same thing, deletes the batterystats.bin.

Thank you for your time. You explained really well and i appreciate that... So, to use the calibration apps i need to have root access... should i search a tutorial on that or is there one on the forums? If the calibration can't fix it, should i get another battery? Thank you again! Maybe i should try to buy a new battery first... is rooting safe? can i get back to my old firmware?

Well, yes I guess you should root your phone first, but I'm not sure
A guide on how to root your Sensation can be found here .You should only do the steps 1-3.
If you don't want to root there is another method somebody wrote (I haven't tested it personally)
1. Turn off your phone.
2. Fully Charge.
3. When getting 100% signal, unplug quickly.
4. Pull off the battery and put it anywhere.
5. Wait for 180 seconds minimum
6. Put back the battery on the right side.
7. Turn on the phone.
Than you should be OK:good:
If you get the same result after "battery calibration" I suggest you buy another battery.
Hit THANKS if I helped you
Hello, i have two more question related to this thread... Is there a way to calibrate my battery without root access? And will buying a new battery surely fix my problem? Thanks again!
You might be able to get a calibration application in the playstore. However most I've seen require root access. But look, they're might be some without root requirement. As for your second question. Nothing is ever 100% guarantee that it will solve the issue. These are suggestions based on the information you provided regarding your issue . How can anyone be 100% certain that will solve your issue. It's defiantly a possibility it will solve the problem but no, for 100% certainty, I don't think anyone can say that. It's defiantly worth a try ! Then you can see if getting the battery solved the problem. I hope it does fix your issue and wish you the best .like I said, no one can be 100% sure but it's defiantly worth trying!Sent from my HTC Sensation 4G using xda premium
Everything said in this topic is PURE NONSENSE. It was even featured on the front page that wiping the battery stats DOES NOT DO ANYTHING. See this article for more information > http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
The only thing you CAN do is charge your battery to 100%, and let it drain to 0%.
Aparently, after i cleaned my battery contacts it DOESNT jump to random values... drains continously.. SO i think the problem is fixed... atleast for a while! I'm new using a smartphone and the battery is a little 2 weak as i was used to my other non-smartphones... I think that's the battery life a 1520AMH can offer me on a sensation! The uptime for it was 6 hours from 100%... thats really weak ( i used the web and games).
Hi
All of a sudden my battery started draining rapidly. See the attached screenshots for ref. I thought maybe it was a software bug since it started happening 2 days ago. I tried booting into the safe mode and the fast drain didn't stop. I also did hard reset with same result. At this point I'm thinking about getting new battery. Just wanna see if xda community has any tips if maybe I've missed something. It's just strange that this sudden degradation happened overnight.
Obviously, that draining is not normal.
In the upper left corner there is a warning that some app is running in background.
When you did the hard reset also you did a restore from some backup? Is the device warm/hot?
Sometimes it shows carrier utility or people apps running in the background. I restored from Google backup (forgot to mention in the OP). Device isn't hot at all.
i stared clean with LeeDroid ROM (had original Sprint ROM on) after wiping the data and the fast battery drain remains. at this point i'm going to replace the batter since it's not a software issue.
I'd definitely say your battery has shat itself. I'd also try something like gsam or battery info in *#*#4636#*#* to see the health of your battery. I'd be interested to know if it reports it as "good" health
It's strange but the standby seems to be better now whereas it was going fast before. Thought maybe it 'fixed' itself, however during a phone call (4min) I lost %3. That's definitely not normal 4636 is not showing any battery info. Can't find anything in gsam showing health status of the battery. Is it in pro?
If the battery drains fast during calls can be due to poor/weak network reception (the modem tries to maintain the best quality and scans the network over and over).
3 sot with 50% (or little more) battery left is a good value, in my opinion.
Oh, when recoveries are made due to some problem is better to not restore from backups. In that backup can be the app or setting that is causing the problem.
Anyway, with the last google play services (14.7.99) I also have noticed a bit more drain during standby.
Sounds like you need to replace it

I have about the same issue. The battery is draining too fast and it's very noticeable when idle, even when idle in safe mode + airplane mode it loose 20% during an 7 to 8h night. I tried all htc nougat and oreo official and unofficial roms and nothing fixed the problem.
I also used the htc diagnostic tool to determine whether my battery is "good" or not and..... according to the diagnostic tool it is "good". Notice that according to diagnostic tool the battery is defective only if it goes from 100 to less than 75% during the test. Mine goes from 100 to 93 during the test which consists in showing a kind of dark grey screen at full brightness during 1 hour.
Even with a battery rated as good I decided to sent my device for repair because it was not good.
I received the device back and it has not been repaired because it passes the diagnosric tool test. test.
So i'll replace the battery myself as soon as i'll receive my new battery.
I suggest you to run the diagnostic tool test and if you get a decrease from 100 to less than 75, they should repair it under warranty, if not, suggest you to replace the battery yourself or pay somebody to do it for you.

I already ordered the battery and will do the replacement myself if the wait times are similar to those of screen replacements. Plus everything points to a bad battery so another test with official app is pointless. Sounds like we both will be doing the swap ourselves.
So I put new battery in and the drain seems slower than before and the charging is not erratic (jumping). When I was removing back cover the black layer came off so I figured it'd be good time to try clear cover mod . I like the look but unsure if anything will interfere with the radios and such due to the missing protection.
