I was an idiot to trust this phone to wake me up.
I set Galarm yesterday night to wake me up today at 7:05AM. The battery read 27% (at 11:00PM, when I went to sleep). Using Galarm I set the phone to "Flight Mode".
The phone's battery run out during night and so I woke up late and was late to work.
I simply can't trust this phone to wake me up. One night the overnight drainge is only 3%, but the next night it's over 27%.
I don't understand what on earth could drain the battery so much if the phone is in standby and in flight mode...
Why not just plug it in overnight?
The battery indicator is essentially guesswork - you can't be exact other than when it's full or when it's empty. If it said my battery was at 27% I wouldn't trust it to last 8 hours, even in flight mode.
Last night at 11pm my battery was on 51%. I set my alarm to 7am using the HTC Sense alarm. It woke me up having only drained 4% over night. I didnt do anything special...it just worked.

When the phone is with me during day, if I don't use it, it hardly drops 1%.
I had the Kaiser and Diamond and Touch HD, and could always trust the battery indicator (that if it read 27%, it would easily last the night).

Yes, sometimes the overnight drainage is only 3-4% for me too. But then at other nights it goes crazy...
The bottom line is that it can't be trusted.
I will try to use BatLog overnight to figure out what causes the drainage.
I usually go to bed about 11pm and alarm I set at 6 am ; everymorning I noted the battery only drains about 5 % - I consider this as very good. If your battery drains a lot , you just have to check which programs are auto accessing internet to update - eg Weather, programs like Spb Traveller, RSS programs, Tweeter ( MoTweets, Twikini etc ) etc : disable all these unless you really need it

But the phone was at "Flightmode".... nothing could access the internet.
Hi all,
In my case the battery over night from 11PM till 8AM goes down with 3%. I monitorized for 4 night till now and the results are the same.
In my opinion is preatty ok this drain and is in normal parameters.
It might be that if goes more then 7% then somethings wrong and perhaps there are some app's running in background or the phone trying to access GPRS or something like that.
Regards,
Seba
I have the same problem. BUT only if battery is below 50% it drains to 0% over 7 hours! if it is >50% it drains only 3-5% over night. I have perfect network connectivity, set to GSM only, softreset before sleep, my location off, no internet connection. Nothing helped! Is the battery f**ked up or what is wrong with it?
Unlike the HD I have owned, my HD2 battery seems to drain very fast as well, Its like every hour it goes down 2%, from my experience, some brand SD card will also drain the power sharply.The microsd card I have used for my HD is a Sandisk class 2 16GB, and for the HD2, is an A-data class 6 16GB, so I am curious which micro sd card are you guys using? Lets see if this is the one of reasons..
Having used the phone for the last 10 days , i found that the internet acces and the vibration mode with ring is the mail culprit. having turned the internrt acces option to off , i was able to use the phone for more than 24 hrs without charge. also the bluetooth and the wifi options drain the battery extremely fast.
I installed the BSB 1.6 teak and have set both the "Power save" and "WiFi power save" to ON, and it looks like it has made a difference. I was charging the phone everyday until the BSB Tweak, now I'm day 2 and still have 28% battery.

Every hour 2%. This means only after 50 hours (more than 2 days) your phone is empty. I wish mine was.
well, If I leave my phone totally unused, no incoming phone calls, message, emails either.I believe it won't be booted after 50hours.
I have just fully charged it, and close my location service and weather auto-update, hope it will help to save the battery.
Good night,we'll see tomorrow.

i find that installing the 1% battery indicator as a tweak drained my battery 40% overnight. hope this helps
..
Over night(about 7hours),my hd2 battery drained to 64% from 99%,no background programme.
I do have the 1% battery indicator installed, but I don't think it makes difference, however, I will give it a try remove it, test again.
I have uninstalled the 1% battery indicator, and disactive flght mode, either works.
Since I had such problem before http://forum.xda-developers.com/showthread.php?t=606093, while charging the battery on AC power,the LED light is flashing（normally it should be a solid amber light),
I had drained my battery totally even the backup battery, then recharged it via usb on my pc.It charged very slowly to full, however it drains super fast.
I guess theres something worry with my battery, just waiting for the battery that I have ordered before Christmas.I hope it will be solved by replacing the battery.
Can you please post here if a battery replacemant solved the problem or not? Thanks in advance!

Trying to figure out 1) cause of battery drain and 2) poor power mgmt.
I had a fully charged phone yesterday at 5pm, leaving work.
When I tried to turn it on this morning it was completely, completely drained.
I have 4min timeouts set on the phone for backlight off, and 5min for device off when on battery. I had WiFi tuned off, Bluetooth on.
I did have Wayfinder and GPS active on the way home, and may have just turned off the phone. If I turn off the phone with Wayfinder active, would this continue to drain the battery, GPS reception is passive, is it not ???
How come the battery drained to such an exent, it took 5 min on a charger before it would even power up, from a full reset and WM load.
My old XDA would hibernate at low battery percentage, and still have a reserve charge to keep the phone content/settings intact.
Any views, suggestions.
Peter
When I first got my x1 end of last year, I found I only got around 6 hours out of a battery.
Now I get about 36 hours of normal use out of one charge. Including 1 hour of gps each day/ half hour of wifi.
What worked for me was to, reduce back light time to 10 seconds when standalone. I also found S2U unlock drained the battery, so I now use the standard unlock.
Also, ensure that no auto updates (only manual) are done e.g SPB weather, insight RSS etc.
I have also changed my battery to a Mugen 1800 mAh. This seems to have increased my time by around 25% on average use.
S2U2 no longer drains my battery, one of the old versions did and so did the old version of AE Button but they are both good now, I get min of 2 days and max of about 5 depending on load of use... normal use is about 3... (internet for emails and dling rss feeds and some reading of forums 1 hour, reading books/texts about 4-5 hours and listening about 2hours plus calls and texts is a normal day for me...)
GPS does drain your battery pretty quick though...

There is no poor power management in there.
It is all because of wayfinder. GPS is still active if you leave Wayfinder active all the time and it will drain the battery supoerfat.
Try closing Wayfinder and you will what I am talking about.
I found out that any Battery applications greatly reduces my (juridically - my wife's) X1i lifetime.
AFAIK to measure any battery charge you need to short circuit it for a millisecond or so and measure the current, not the voltage. When any Battery software does it (through the hardware) every few seconds your battery looses its charge faster.

I am running Home++ and its fairly decent as far as drain goes... I dont notice much more than when its not running...
Tks for all your feedback.
I am fairly ok with normal use and battery life.
In this particular instance the drain happened so fast, overnight, and I was not using the X1 at all. (or so I thought so).
So I am curious to know what caused the rapid drain, and why the X1 does not have a more controlled low power close down.

I have already explained. It was the GPS application that drained the battery, nothing else.
Just as a test try leaving it for as few hours running again and you will see.
battery drain
I do have the same effect. but I do not use GPS or wifi at all.
Sometimes it put the phone down, screen disabled and fully charged. No application running.
Next morning the battery is dead.
It happens about once every two weeks without any sign why...
My solution: I bought a desktop charger which is able to charge a second battery and simply exchange it, when this happens again.
Not ideal - but right now we seem to have to life with it.
do you have an old version of S2U2 or AE Button plus on your phone? And I have also read that batti used to cause drain problems... this might be the case with yours(?) if you have none of these installed then I am of not much help...
If u use Push email or active sync, Google sync Hotmail sync any Email sync on arrivel option ur battery will only last 5hours cause the phone is using mobile web at all times and constantly sending and recieving, turn it off an ur phone will last over 19hours with out charge... EG i turned my email sync off at 10am an the batt level was 60% didnt charge it till next day 11am when the batt levels drop to 20%
Is your X1 fairly new?
I experienced exactly this issue about a week after I bought my X1. No apparent reason for it, but the battery just drained right out overnight.
Strangely, the same thing happend about a week after I bought a HTC Touch Pro.
In both instances it has happened only the one time. Since then things have been normal, or drains caused by known software issues (like the buggy version of S2U2).
As earlier suggested, I loaded the Wayfinder app, with its GPS active.
I tuned off the phone when the app was on screen.
Left it for 3 hours, and there was a noticeable drain of the battery.
Lets hope the new WM 6.5 improves Power Mgmt, and has a more elegant low power handling.
Do you have G-Alarm installed? My Battery gets drained very fast when I have this installed. I tried many different versions within the last few month, allways the same.
I experienced this last night for the first time with my X1. I left the X1 on the bedside table at 11:30 with 90% charge and was awakened by the battery low alarm at 6:30 am (not good).
The only thing that I noticed that was unusual was that my X1 had been connected to the PC with ActiveSync in the connected state. I shut down the PC and then unplugged the X1. In the morning after the battery low alarm I noticed that the phone thought it was still connected. I use SPB Phone Suite and it was still showing the Cradle profile. This would not change in the automatic mode so I had to reboot the phone. Everything has been fine since.
So ... I am wondering if ActiveSync can sometimes go crazy and drain the battery more quickly??
I have a faster draining battery since i installed g-alarm. can anyone confirm that?
In my case I dont have G-Alarm installed.
Well my battery is not draining that seriously. it's ok i guess.
But maybe you should try what is suggested in the last post of this thread:

ok guys as advised by someone i fully drain my vodafone magic till it dies and then charge it to a 100%.
last night i did the same just before goin to sleep,when i woke up in the morning the battery was at 76% after about 8 hours.I just had 1 missed call,1 sms,1 tweet and 1 email.
How can the battery drain so fast for no work at all???
pls help......
Do you have alot of widgets running? What do you have switched on, Bluetooth,GPS,WiFi? How often do you have the "Data Synch" set for? All of these drain the battery, if they are all working at the same time it goes pretty quick.
Clinton
Woa! For the battery to drain overnight to 76% is crazy. never had this problem with my magic. It actually last very long.
But 76% overnight most likely means your battery is faulty and or you are leaving gps,wifi,and have quite a few things running on the phone like ClintonH stated.
however if you have everything off, as well as the brightness set low. Then contact Vodafone and let them know your issue. they should replace your battery at a free cost.
I suggest people use their battery for a week or 2 to see better results with their battery life. I started having poor battery life with my magic but now I can last about 2 day before I recharge it again.
As other user mentioned, it also depend what you have on or running in the background when your phone is on standby. I suggest you use task manager applications to kill unnecessary applications that might be running.
thanks guys
nope i have gps bluetooth and wifi turned off
i turned the background data off from settings
will try gettin task manager and see if it makes a diff!
thanks once again

I read a quite interesting post in the vodafone forum.
A user complained about the battery life of his HTC Magic. Check the answer from Wayne_Vodafone:
The HTC Magic employs a battery that requires overcharging and topup charging. You must charge it as much and as often as possible. The more you charge the better the battery life becomes. So after a few charges you should see the benefit of this. Letting the charge drain out undoes this so try and charge as often as possible

It actually seems to work. At least for me, try it for yourself.
I have to charge my HT-03A every night if I do not want it to die the next day. I am assuming that is why HTC gives you two batteries, because the battery goes so fast. As long as you are able to carry that second battery around with you, and be able to charge it every night, I don't really see a problem. But for it to go from 100% to 76% overnight means you are running programs that you do not need to. I will add that I have Wi-Fi continuously on, and my Contacts and Calendar are continuously synchronized. With barely any use I am usually at around 50% by the end of the day.

You never want to drain a Lithium-Ion battery. NiCd batteries have memory, in which it's better to drain them. But not Li-Ion. They will die quicker if you do

That could be right.
Depends on what's running.
Where are you checking for 100%?
If you are charging until the green light comes on - that's 90%. The phone takes longer to charge passed 90% than it does to charge up to 90%.
I charged to 99%, and drove around with the GPS on for a few hours (about 2) and came back at about 75%.
However some days, when I charge my phone over night (true 100%), I can listen to music on my way to work (40 mins) on my phone, play with it a bit at work, and 3 hours later it will say 94%.
So, the battery is very touchy it seems...
Try turning off 3G (It's still pretty fast on 2G, try it for a day)
And also make sure GPS is off. Keep your brightness no more than 30%, and make sure WiFi is off. Make sure you don't have any widgets that connect online either.
You should get good standby time
Use apndroid to save battery life
Download apndroid from the Market. Use it to turn off the cellular internet before you go to bed and whenever else you want to save battery life.
There's also an app called Spare Parts in the Market that could help you. As well as giving information about your battery status and battery health, you can also see stastics of your application usage and battery history. A very useful app!
Plus it also enables other features like enabling fancy animations for the keyboard and screen rotation.

Hi guys,
I have a problem with my Jade. I've charged it last evening and I've barely used it. When I've went to bed it was 96% charged (ARIELbattery) and 10 minutes used.
This morning, when I've woke up, The battery was 33% and and the phone was 34 minutes usage time.
Something is wrong. Since there were no bluetooth, no wifi, no anything activated. And for sure, nobody played with the phone during the night.
This is not the first time when I see this behavior, but is the first time when the decrease is so big.
I suspect an app, but I do not know which of them. How can I see it?
Do you have other suggestions?
thanks!
There are some possible reasons:
Some SD-Cards seem to drain battery, so you can take it out for a test.
Some additional software is told to drain battery. Did you install something?
It is also helpful to switch to "flight-mode" over night. This normally reduces battery drain to nearly zero, if no additional consumers exist.
Hi,
Yes I've installed some software, like gAlarm, S2U2, icontact,ThumbCal, Skype, etc but last night none of them was started.
What can I do with the SD Card?! I need the SD-Card. Which card does not drain battery and which does?
I cannot turn off the phone over night.

I've read those before posting, but there was no answer to my problem. I have 67% drop of battery in 8 hours without touching the phone.
This is most likely that your device goes to screenoff or unattended power state instead of sleep. Your power settings might be corrupted. To change that go to your power settings advanced tab and change everything there (checkboxes and sliders), press ok and then change them back as they were, press ok. I'd suggest to keep the device turning off in one minute while on battery and none of the checkboxes for cord powered mode. There is a really freaky thing that even if you get your device to sleep with power button it will go back to screenoff mode after time specified by the turn off device slider while on battery IF you don't have that turn-off-while-on-battery checkbox checked there.

Thanks for the answer. But I do not really understand what you are saying here.
My power settings are: 30sec for Screen Light and 1 min for Device (on battery).
None of the check boxes is set for the case when the device is powered.
It could also be due to the battery defect. After some time the battery could lose its storage ability (because of the defect), despite the mAH stated.
As a comparison, my battery is nearly one year old. On full charge, overnight drawdown (on sleep mode) is about 2%-3% .

I have no own experiences with this programs but Skype for example needs permanent connection to internet when activated (be care of the background job!). This uses data connection and this drains battery. I can not quantify this in %. In addition Skype does not allow the system to switch to deep sleep because it needs permanent connection!
None of the app was started. I just have Skype installed, but it was not used.

I found some German threads that discuss a problem with this software and battery life. Some loose 10% over night others 50%. I think you should try to uninstall (and afterwards soft-reset!) for a night and see what happens.
Please keep us informed.
First of all, I've disabled the 3G. Now it only gsm with gprs. Since I've done this it seems the battery drop is ... super ok. If yesterday morning I've had 33%, this morning I've had 20%, so 13% drop in 24h, and the phone was used normally as before.
last night the S2U2 was not started.
I will wait until the battery level reaches 10% an I will do a full charge.
I will keep you informed. Thanks to all for advices!

Hi,
So now, 2 weeks later... after setting my Jade to GSM only (no 3G) I get 7-8 days of normal usage. As I said, before I always had to charge it the third day.
Normally, i get -28mAh drain in standby. When the screen is on around -130mAh (for wake up) and then -70mAh. In a gsm call i get around -250mAh.
I did not switch the phone back to 3G yet, but I will and I will see again the battery drain.
PS: the values were provided by Mobadi.
i believe i have S2U2 installed... and my phones fine!
i have the overloaded rom... and battery life seems great only needs charging every 3 or so days and i do use it quite alot!
so...
after some time of testing and re-testing I still have, from time to time, the behavior that during night I see a massive drop in battery level and an increase of the usage time.
I do not know what is going on, but I suspect that some app is waking up the device to do some work (without turning on the screen), and the Jade cannot go to sleep anymore for a while.
I've notice the same behavior on a HTC Diamond 2.
Since none of the app I have installed on my Jade are installed on my friends Diamond2, I have no idea what app could do that.
If anybody has any idea, feel free .... I am idea-less!
I've made myself a little application to log the current values of the power data. So, I've saw that my phone wakes up each hour by himself, without turning on the screen, does some work (cca -70mA) and after 30sec goes back to sleep.
Any ideea about this?
Ye, my battery just went from 48% to 3% in about 3 minutes. Does anyone have any idea why this is?
Same problem here. From about 43 % down to 7 % while it started to charge the battery with the original charger. Afterwards the Tab didn´t charge at all. Battery drained and got very warm.
I Called Vodafone and was told i have to send the Tab in for fixing. I hate waiting for the tablet 3 weeks.
Update: After 2 hrs. of waiting the Tab cooled down and i was able to start it again. Did a factory reset and was able to charge again with the wall mount charger.
Just wanted to bump this as my battery life is miserable and it discharges really fast in standby...
My HTC desire has been on for 52 hours, used for a lot of stuff and is at 20% battery.
The Tab charges to 100%, I unplug it at night and in the morning it has lost approx 10%, I leave it a few more hours and it't down to around 60%. This is with no use and no apps running!
I've tried killing apps or leaving them in memory and it doesn't seem to make much difference. I also use setcpu and have a profile where the CPU speed decreases when in standby to conserve battery?!
If I charge to 100% and use it constantly, I get fair life out of it maybe 4-6 hours of light use - some streaming over wifi, web surfing, kindle, sudoku etc. If I use it occasionally or heavily though, it dies very quick and if I leave it at about 40% on the evening, it's generally dead in the morning.
Why does it discharge so fast in standby??
Check to see if it continually searching for a signal. I've noticed that mine loses a lot of power constantly searching for a signal, cellular and wifi. So, I used airplane mode to conserve power. Remember that it syncs to different services that require it to periodically download data. That may be your issue.
Sent from my SCH-I800 using XDA App
Thanks Chuck, I use it in airplane mode all the time and only use web over wifi (bought unconnected in the UK). Would it still be syncing for email etc? I didn't think it could turn on wifi and sync itself but only when I turn wifi on. I always turn wifi off when not in use. I had problems with widgetlocker asking for superuser permission quite often and that killed the battery quicker so I removed that until it's fixed and saw an improvement.
I'm not seeing the times that other people are though, losing at least 10% overnight and there's nothing really running.
I installed battery doctor and the times it quotes are high for different types of usage and nowhere near what I'm getting.
I'll make sure email and calendar are set to manual update, adjust brightness etc and see what happens. It seemed better when I first got it so perhaps an app is draining it? I installed system panel to monitor this but it's hard to see what is actually draining it, any recommendations anyone???
Quite disappointed at the moment, ipads barely drop 1% overnight and I'd rather not have to turn it off to conserve battery when it should maintain it in standby...
Check the task manager and see what application are running. Also you can go in settings- about device - battery use to see if a specific application is using your battery out of normal. Also , the display is generally the battery hog, you may have set it to a super high level. One last thing you may have the buggy 3d gallery app, and it will show in the battery usage.
P_
this is an interesting problem. its very similar to the Apple Macbook Air.
The Macbook Air was very thin - very nice looking - however it needed to depend on wifi to do most things.
the association i am trying to build here is this: the Tab needs a bluethooth headset so you dont get all your calls broad-casted over speakers and that could drain the battery a lot.
for me the battery drainage didnt seem so bad and its been on for the last 36 or so hours. the battery icon didnt look like it moved so much and i was impressed considering this thing had a gigantic battery. then i loaded up a utility that read the battery and said i had 59% so my jaw dropped. not only is the battery indicator wrong there maybe rogue processes casuing the battery drainage. and this is on 2.2 which is supposed to be somewhat battery efficient.
i dont know - frustration is what i am all about here with this thing. it seems that every time i buy a new android device i want to move to another android device. no one is getting the damn thing correctly setup.
Am at work right Now, Charged the tab overnight, just few minutes ago my battery said 60% left and now the tab is completely dead, wont turn on, I ll wait until i get home to charge, fingers crossed.
Change the battery...

Just wanted to bump this as my battery life is miserable and it discharges really fast in standby...
My HTC desire has been on for 52 hours, used for a lot of stuff and is at 20% battery.
The Tab charges to 100%, I unplug it at night and in the morning it has lost approx 10%, I leave it a few more hours and it't down to around 60%. This is with no use and no apps running!
I've tried killing apps or leaving them in memory and it doesn't seem to make much difference. I also use setcpu and have a profile where the CPU speed decreases when in standby to conserve battery?!
If I charge to 100% and use it constantly, I get fair life out of it maybe 4-6 hours of light use - some streaming over wifi, web surfing, kindle, sudoku etc. If I use it occasionally or heavily though, it dies very quick and if I leave it at about 40% on the evening, it's generally dead in the morning.
Why does it discharge so fast in standby??

I am experiencing the same thing. Tab on flight mode and charged to 100% overnight. Unplugged at 9am, still on flight mode with no apps running, and it is 88% at 2pm.
12% drop in 5 hours with no usage whatsoever is way too much imo, comparing let say to my HD2, even not in flight mode. Wonder if they have a bad batch of battery for certain tabs........
Just wanna report back after my last post. When the percentage was dropped to 85%, I did a reboot. And guess what, now it displays 95% !!!!!!
5% drop from the morning til now in flight mode seems right and okay. Does it mean the tab is miscalculating the percent left?
PS.
I have been following the voltage in Spare parts this morning. All settings are the same (no apps opened, same screen brightness and in flight mode. Only turn on to record voltage)
94% - 4087mV
91% - 4081mV
88% - 4075mV
85% - 4067mV
But then after the reboot
95% - 4040mV
Man, I am not sure whats going on here........

let me jump in here again and share a similar deli-ma i had with my X10i.
while i was messing around with some custom roms i decided to stick to one that looked somewhat nice. well the funny thing is the battery indicator would always display 100% and for about 4 hours it would drop ever so slightly. then i removed the battery and put it back in -- the battery indicator showed 0% and i got a red light flashing ....
after screwing around with it for a bit i re-flashed the stock firmware from Sony-Ericsson and magically my battery meter and my battery worked fine.
so to sum up -- it maybe a software issue like the one i had on my SE X10i above?
My Huawei has a horrible battery life. I'm using stock rom (rooted of course) and the battery drains really fast, like 5-10% an hour even in sleep mode. I have used a battery calibration app recommended by someone here in xda, but I don't think it made any difference. My last Android phone used around 1% an hour, even with data and sync on, but with pretty much the same settings, I can hardly make it through the day with my Huawei.
So, what to do? I don't need the battery to last for days, but having to recharge twice a day at worst is just too much.
My battery drops around 7-10% overnight.
Probably a defective cell?
mine after i installed custom rom (b160) and a battery calibartion in flight mode during my sleep after 7 hours that passed and woke up it was 1% dropped and now 7 almost hours afterwards in normal mode it has dropped 7% with very light use of course...
i want to say just that with gsm active it drained 5% more than in flight mode...
so something must be going wrong , like you don't have a good signal and it uses much power to keep your connection alive and have better signal....
i must say that i have a profile with setcpu when the screen is off with min 122 and max 460...
and just for the record i think that with custom rom also mine was dropping more...
i don't know why although...

Noticed this myself. i use spotify alot on the phone, walking, bicycling, at the gym. and it drains a whole lot of power even in offline mode. but if i set it in flight mode the phone last for hours and hours without even dropping 5-10% of power. but when gsm or data traffic is on the battery life just drains out so quickly! so it is definitly something serously wrong in this rom. Im hoping gingerbread is coming soon to this phone, so maybe all these small issues has been fixed.
I've found highly variable battery life. Sometimes it's awful, almost 50% overnight when it's sleeping on my nightstand, other times it's much better and only drops 7-10% under those conditions.
One thing is Google Maps, even when not in use it seems to suck battery like crazy if it's loaded (and it has a habit of getting loaded even when you don't run it or any apps that use it). There's a long thread on this in the Google support forums, but no sign of a fix from Google yet.
I've found doing a 'force stop' on Maps if it's running often helps, another thing is to reboot the phone after you charge it, that seems to fix it for several days sometimes, but then it starts sucking juice again for no apparent reason, so I tend to reboot it after each recharge. There can also be other apps that due to bugs can suck battery, for a while there app killer did this but the author put a fix out pretty quick and it shouldn't be an issue now.
Just noticed that there's an Android update from Huawei now available for download, maybe that'll fix some of the irritations and help with battery life; I'm off to install it!
where can you find that update? through phone's settings->check for update (in my case it says i got the latest version) or online?
My phone has been on for nearly 48 hours.. charging it right now. I played, connected to wifi, browsed the net, facebook, gmail etc.. and I really played hard on it for a few hours.
30mins ago it switched off, dead battery.. I'm quite pleased with the battery life

Exactly the same problem here. I formatted now both the internal and external SD card, let's see if that helps.
edit: No it doesn't. The problem seems to be that my phone doesn't sleep properly. I charged it to full, then turned the screen off for one hour. App called Spart Parts shows that since last unplugged, time spent without sleeping is 36m.
it took mine 2 weeks to get to the full battery life. now i get 36-48 hours from it.

After 5 weeks i get about 12hrs. No GPS, no 3G. About 10min ago i took the charging cable off. Now Battery History in Spare Parts show that "Since last unplugged" time spent without sleeping is 10m 33s (99.9998%), and time spent with screen on is 3m 23s.
im thinking of buying this phone is it available in India ? also can this device be rooted n what about the custom roms ? are they available as there is nthng on XDA :'( . And what about its battery life even being 1500mah is it so awful ?

something is running background...
after i removed all these applications such spare parts and other i got 3 days with light use of course...
with screen off after 3 hours it drops 1% !
and this is fantastic for me!!!

Now after factory reset it seems that this is fixed. Over night with Wi-Fi and all sync's enabled, it took about 20% which is quite ok.

The problem is back... For some unknown reason the phone doesn't go to sleep and starts to use more battery.
Battery History:
Other usage, since last unplugged:
Running (100%)
Screen on (3,2%)
Partial wake usage, since last unplugged:
Android System: Total time: 13s
Dialer: Total time: 0s
Maps: Total time: 0s
It seems that reboot helps with this every time. After reboot, running-% is 32.9 when screen on is 6.5%. It would still be interesting and helpful to know what causes this.
its an android thing

Do you mean it's a common bug, or is it normal thing for Android to not go to sleep after few hours of using the phone?

That's not true. My battery history shows that correct(as far as I can perceive) running time.

I get most of the time also. But after charging, at one point (after some time) for some reason the time spent without sleeping goes to 99%. The problem is, that the partial wake usage doesn't show that something is wrong. Usually restart helps, but sometimes it can be already late, because 100% running has already taken quite much of the battery.
Also, when the time spent without sleeping is 99% or 100%, the CPU is still NOT in heavy use. So something just prevents the phone to go to sleep mode, and it seems that it is not the CPU that causes it.

I got it through the phone, it was the 2.2.1 B136SP02 update. Not online at Huawei website. It doesn't seem to have improved battery life alas (or the frequent WiFi dropouts I've had since new, particularly while downloading app updates). Main feature of the update is WiFi tethering/hotspot support, at last...
What seems to have worked for me after a couple of weeks++ of REALLY crappy battery life is a battery stats wipe.
FullCharge while the phone was off. First boot in recovery, battery wipe and then i just let it run close to dry before the first charge (almost 48 hours of medium use). Note here that i am now using the charger that came with the phone because i noticed that my generic usb one had an output of 0.7A instead of the full 1A of the factory charger.
Another point arose however. Does anyone else have stability issues when battery drops below 25%? I am talking about some serious crash/reboot/lag/noradio issues.
