I just found another painful bug....this one is related to charging (battery). I normally put my qtek on charge all through the night when I go to bed. For the last 4-5 days I have been unplugging the device when it showed 100% charge, put it on standby (no wifi,btooth,gsm etc.) and made sure there were no applications running. I usually leave it in the standby state for 2 hours while I finish my morning exercise.
whenever I return, I see a power loss of 20%!! I was shocked to see how I could loose 20% in 2 hours ith my device on standby mode. this time, I even made sure I pressed the power button before I closed the lid, and still...no luck :-( I still lost 19%
I guess the problem is, when the charger is connected and the battery gets completely charged, it stops charging further. I guess it reaches a fully charged state within 2 hours, and the battery starts to drain all through the night...and wm5/htc don't start charging once again when the levels go down....i'll have to do a cuple more tests until I can totally confirm that this is the bug...until then, are anyone of you guys experiencing the same problems?
Another thing I forgot to mention, once again I charge my battery from 80% to 100%, and it lasts through the entire day(12 hrs) and drops to only 40% with highhh usage (bluetooth ON throughout, gsm on with 3hrs talktime, and some light gprs usage). so it really is not a problem of my battery as I see it!
Cheers,

Hmmm. I hate to say, but I don't see that problem. But I do have the unlocked JasJar Universal from HTC, not the qtek. If this happens with other qtecs, maybe they load a custom software that is acting up. In fact, I could leave the device on for two straight hours off a 100% charge and I don't think I'd lose 20% unless the phone was on too.

have you tried charging your device for well over two hours before unplugging? (around 8-9 hours of charging for instance?)
I don't really think it has anything to do with the qtek rom/device. the qtek rom has the least ammt of customisations on it...
I still suspect that the charging process halts and it starts to drain the battery....but the os doesn't reinitiate the charging process once again....hmm
I'll have to wait till tomm before I can do another round of checking....tomm, I want to charge it....and before I unplug, I'd remove the battery and put it back and see what it indicates...I suspect that the power would have already dropped to ~80% by then...that's the only explanation I can think of at the moment....

Hi Dreamtheater!!!
I exactly follow you as far as charging is concerned and I hv a Jasjar....just to inform you...I started charging yesterday at 11.30 PM and just got up to see the charge..it is 100%...no power loss...

it shows 100% for me too...but in just 2 hrs, it drops to 80% which is weird! from then on, it drains normally...
I still need some time to nail the exact cause for the problem...hmm!

Hey dreamtheater, I charge my Exec overnite everynite just like you. Usually at least 7 to 8 hrs everynite, but I have yet to experience what you mentioned here. My Exec always start fresh from 100% and by the time I get home at nite, it will drop to about 70% so no, I'm not getting the batt drain issue like you do..
I did not experience any such behaviour with my Qtek. It charged fine over night and had 100% battery when unpluged.
Are you sure your's does not wake up for some reason after you suspend it?
Dreamtheatre, I charged my XDA Exec overnight (7 hrs) and after 2 hrs with GSM/UMTS radio on the unit lost 5% battery charge.
@DT,
You need to set the device to switch off after a specified time interval. This can be done by going to start>settings>battery>advanced and check the device timeout box. I usually set it to 1 minute.
Last night i was browsing on my JJ and fell asleep while doing so, IE and notes and inbox applications were still open. When i started, the battery level was 93%, i browsed for about 10 minutes over Wifi before i fell asleep. The device shut itself off and when i woke up the battery level was 82% which is prportionate to my 10 min WiFi use and probably 1 minute standby time before it shut itself off.
Try it out, i'm sure you will stop seeing the massive battery drain
Cheers.
Another thing. Contraty to what people think, keeping the universal's battery topped off improves battery life. Prevent it from dropping all the way to say 30% or so. You will notice the difference in battery life in just about a week or so
Another source of battery drainage i've found is when i'm charging my Exec from the USB connection on my PC - If I leave my Exec connected and put my PC into standby, it will literally suck the life out of the battery over the course of a few hours!
I think some of you have got me wrong...let me restate the problem...
I charge all night
Wake up with 100% charge
Pull off the charger
Leave it on standby for ~2 hrs (no apps running, gsm, wifi, all off)
Come back, and find a ~20% drop
Back to my findings now.......
Another morning, no luck :-(
It had 100% charge...I pulled off the battery, put it back in and restarted....still showed 100%, so I guess it really was fully charged after all. This time I turned off receive incoming beams as well....left it for a couple hours, and was disappointed to see 82% when I got back :-(
However, through the day I get excellent battery life....all day's use ends up consuming roughly 30-40% charge which is excellent compared to my prev xda2 which would comparitively loose all of it by eod. I guess if I park my device in flight mode it tends to start draining quickly....now that's my only available reason or cause that I can think of....
tomm I guess I won't put the device on flight mode and leave it just On instead. This is weird because its just me having this problem :-(
San
PS: I'm using the regular ac charger itself for charging...hmm
DT, I disabled PowerSave and switched off the GSM/UMTS radio on my Exec. After about 8 hours I had lost about 30% charge. So your 20% does seem high. It could just be the battery as loss of charge is not linear. Why not let it drop to say 60% and then do your test again. By the way there spare batteries seem to be available now for the Universal.
Dear All,
I have a strange problem here.
I just purchased a used wizard and installed a new t-mobile rom, but, once I connect the charger or the usb, the orange charging light starts blinking!
The battery doesn't charge, but drains very fast.
I re-installed another rom, but it's the same, and I installed another, but also the same.
I checked the battery on another phone, but nothing was wrong with it, then I installed the battery of the other phone on my wizard, and it did the same problem!
I checked another charger, but it's the same thing!
The phone is fully functional, and works 100% other than when charging it!
Any suggestions???
Same problem here. The battery drains almost emidiatly when I charged it. After a couple of time it wont even charges anymore. Tried 3 batteries. All batteries seems to have died. Horrible.
Please... anyone recognize this problem?????
To add: I put in a brand new OEM battey from Sanyo. Charged it with the wallcharger. Then when I put on the device it drains almost imediatly. A brand new battery !! Then tried to recharge the batery and then the phone shows a red led light? What is going on!.
OH, AND NOT FORGET i DID install a new ROm from Moski but the same problem. So, replaced the ROM and battery. Is the wallcharger defect or my QTEK 9100??

Sounds like a defective wizard to me. Might be time to return it and get a replacement.
If you have already purchased new OEM batteries, and you're still having this problem, one would have to assume that it's the charger you're using. A buddy that works with me bought a mini USB wall charger for his Cingular 8125, and on the 1st charge, it completley drained his battery, and it was unable to charge again. $50 bucks later for a new OEM battery and charger, and never had this problem again.
Thanks for the responces. I ordered an aftermarket charger and hope that that solves the problem. I recently bought it for about 210 euro 2ndhand. Sometimes it does startup and looks ok but then in less then a minute the power dies. I will look after the 5 volts and 1 amp. on the new charger by the way.
Once again, if someone recognice this problem I really are interested in the solution if found.
Offourse I will let now if I found out. I'm praying that the wallcharger is the problem.
i had that problem when i was using the razr charger with my 8125. i thought it was the same because they are both mini usb. WRONG!
i hope this is not what you are doing. is your charging cable oem?
Hi. Got a replacement wallcharger and when i plug it it in the led on my Wizard turns RED emediatly. Charger has the same spec. as the OEM. So. Still a dead wizard. Anyone any thoughts?
By the way. I cant even find out what the red light on my wizard means. Should be orange when charging. Red doesnt looks good.
same problem
I'm having almost the same problem
The red light
My wizard won't start, and by the way, I was charging it with a motorola charger cause I only had the car charger , and the cable is 2 short. I actually charge it several times... a month and some, no problems, till now I posted a new thread,
I don't know what to do ... Can it be the main battery ... mabe my charger depleted it I had resco tools installed an it said that my main battery is at 100% ...
Now when I plug it in the car charger, it does nothing..., and when I plug it in the moto charger it shows a red light.
If someone finds anything, please reply.
I found a thread...
Plug in your pda without your battery inside. It shows the red light. Insert your battery, and the led will turn off. Press the power off button, and, voila....it starts. By the way, after it was brought back to life, I quickly pluged into the usb...and the led turned orange. My battery was 0%
Hope this helps. By the way, it's not necessary to work from the first time. Worse possible scenario, let your pda to "rest" without the battery insite for an hour and then try again. I heard it has something to do with heat...I mean, if it's cold, there are less chances... don't laugh It may be true. For me it worked the first time. Good luck.
I was having the same problem. It was fine for a week using this other USB charger then yesterday it was not charging and today it was totally dead.
Thank you guys for the information
but what is different about the chargers? or USB cables I mean?
There are a few scenarios going on here.. (some of these things people have tried and got the same result, but i want to lay them all out on the table here)
A. The aftermarket chargers you are using may not meet the 5V 1A rating as the factory chargers... aftermarket chargers or even factory chargers for other devices such as motorola have an output of 5v 0.5A. Now the .5amp charger can charge the device just as long as its idle and not draining faster than it can be charged.
B. Defective Charger
C. Defective battery
D. Defective Phone
*Note- i did not mention roms due to the fact that phones will charged when they are completely off (not asleep)
Now that we have identified the possible problems we can start to identify possible solutions. (If your phone is completely dead and wont turn on then you may need to search for a thread entitled "Dead Wizard, Never lets revive" in the upgrading board)
Before you go to bed, turn the phone completely off and plug into the OEM charger that is rate output of 5V 1A, make sure the the orange charging light is on and go to sleep (you, not the phone, its off remember ) If this does not solve the issue then try this same thing with another battery and the same charger, if that fails, then try this the old battery and a new charger.....
If after you do all of this and its still not charging properly then your phone is defective.
if i didnt make much sense its cause i am tired and will clarify in the morning if i can
I'd like to make an observation here about some rather choppy battery life that I have been experiencing with my Wizard. I'd like to know if this is inside NORMAL behaviour parameters.
At 8AM this morning, my battery was disconnected from the charger with the battery fully charged.
Between 8AM and 11AM my total phone usage duration was 10 minutes. At 11AM, my battery displayed 91% Charge.
Then exatcly at 11AM, I turned on my Opera Browser and used it for 12 minutes, after which the battery dipped another 7% from 91% to 85%. I noted this reading at 11:12 AM.
After this I put my phone on standby. From 11:12 to 18:30 hrs, I recieved 1 missed call and a total of 2 SMS plus 4 emails. During this time I have not made or recieved any other calls. At 18:30 hrs, I noted that my battery was at 71%.
My phone is set to send and recieve emails every 15 mins. I have only one pull email account and one push email account.
Other than what I have mentioned above, there was no other phone activity. I do not have any background apps running except for SPB Pocket Plus and the Battery Status Application.
Please let me know if this is similar to what all of you are experiencing or should I get a new battery? My phone still has about 6 months of warranty on it? Will I be able to get a replacement for it on these grounds?

from what i can remember when i had my wizard i think that sounds pretty good actually...
thanks for that shogunmark. Do you have an approximation as to how much battery drain there would be for apps like Opera? 7% in 12 mins seems to be a lot. Also I have a feeling that if Opera is running in the background, the battery drains very quickly even though the device is set to go into standby after 1 min of inoperation. I can't confirm this but I have a feeling this has happened to me.
Also, since my messaging app checks for email ever 15 mins, how much of a battery drain will that be?

i cant offer an approximation since it has been a month since i switched to the hermes.. but i can say that i would pull mine off the charger around 8am and by 11pm i would need to charge.. but i used data heavily.. opera, pushmail, at LEAST 30 text a day, and maybe 45 minutes in calling a day. now 7% in 12 minutes does seem excessive, but running java apps is demanding on the phone, takes a lot of resources.
Tips on extending battery life.

I can not aggree with this. I use my windows live and it syncs every 15 min I send out at least 300 txts a day and I use around 90 min of talk time during the day, (thank God for unlimited txt msgs and free nites and weekends). I use the web at least 40 min total and I listen to my MP3s on it on the train ride to and from work which lasts about 20 min from Manhattan to BKlyn. I dont recharge the phone the until I get home around 7pm charge for an hour and go out again.
I have noticed that certain Roms tend to suck out power much like my x-girfriend sucks out my money for Child Support. I have played around with running certian programs and adjusting the backlight settings and this has helped me keep the phone running all day.
My suggestion would be to change the rom and see if your drain contiunes. Then try to have your backlight turn off with in the 10 secs. If you are overclocking your phone when you dont need that extra Mhz turn it back down to 195 or if your really adventurous turn it down to the 170's for some extra power savings. Last but not least make sure your Active Sync is not turning on all the time by adding a fake server source. If all that fails buy the cradle with the spare battery charger and carry an extra battery. Good luck and godspeed!
Use 1A charger
This has been stated already, but after buying 5 extended batteries thinking they were all dying, I bought a 1A charger on ebay. Payed about US$25 shipped, but it made all my troubles go away. A reseller sold me my 8125 with a Razr charger and I thought it would be fine but it wasn't. Use a 1A charger!!!
I keep reading about this "Wizard draining battery" issue on here. I can't say that I've EVER had a problem with my battery draining.
I keep mine on the USB sync cable overnight to charge, pull it off in the morning around 8:30 when I leave for work. At that point, the battery is at 100%. Send/receive 4 - 5 text messages, 15 - 20 minutes of phone calls, PocketWeather updating every 2 hours, emails pulled from my POP3 server every 1/2 hour PLUS intermittent internet browsing and data entry into some of my apps. . . also running WA2 in the background. When I leave work at night, I still have between 77% - 83% battery life left.
Maybe it's just that I keep it "topped off" that I'm not experiencing any battery drain throughout the day -- I don't know. But, I've had no problems with mine.
Just curious what people do with their bricks when their sleeping..I like the idea of leaving it on, plugged in overnight next to my bed in case I get any emergency calls, but is there any possible wear/damage issues to the microdrive by leaving it on for extended periods of time?
About the Microdrive, no, not really.
But I couldn't vote in your poll: I personnaly leave it unplugged and in stand by (not completly shut down).
I am one of those who believe micro-leaking hurts batteries, even if they are supposed to be without memory-effect. So I don't leave it plugged, and when I charge it, I disconnect it ASAP.
That worked for me for all my batteries, which I kept up and in shape for a long, long time.
Thanks for the input Heartofdarkness, I guess I should have added another option to the poll at least one for none of the above. With work and everything, it seems like I am constantly in and out of my office with wifi, and bluetooth on. I'm fairly sure I would not make it thru the entire day on one charge, should I be charging it in spurts of like 30 mins? Currently im trying to get it as much charging time as possible, and unfortunatly thats in short bursts. I'm interested to see what everyone else does as well....... I guess it really doesent matter if the battery eventually craps out, at least its a replacable item.
My devicedoesn't shut down. It's always on 24x7. At night, it's my MP3 player if I'm not listening to my am talk back radio. It's also my alarm clock for the morning calls. Yes, my golf buddy can call me closer to the morning if there is any change in golfing plan, or just send me an SMS. Most probably, I still read and answer to XDA forum on bed until I get sleepy. Sometimes I download youtube videos and watch it before sleeping.
There will also be a scheduled backup that happens automatically at 4am.
Im option E: plugged in and completely off.
I suspect you would be fine if you didnt charge it all day. Mine goes on at 6am, gets a call or two and some browsing through the day (staying on standby otherwise), and by 8pm I have about 80 to 90% left. It then gets heavy browsing between me and my wife between 8 and 10pm leaving me around 30% at the end of the day. If I start browsing earlier than 8 Ill be left with 10 to 20%. Most of the day Im on a 3G/HSDPA network which uses more power than EDGE.
Have you tried going all day without charging?

Never happen for me. A single battery will not last the whole day for me. I use it so much that I normally also use a spare battery. When a battery runs out, I simply go the charger to take out the then fully charged one and swap them. So I never get caught not having any juice. If I'm in the car, then a single battery will suffice as the car battery quickly fully charge it.

Today I went 5 am to about 7:30 pm without a charge. But man was I hurting when I got to the car! Had to plug in right away, down to the short red bar on the top, I think that's 10%.
thanks for the responses
cool, I feel a bit better about leaving it on all night. even if its just standby mode, I need it there for the calls....and who knows maybe ill wake up and wanna check some news
On and powered - Its on the bedside table and runs SPBTime as a bedside clock. I use phonealarm to turn down the screen brightness to zero, volumes to 10% at midnight, then at 6.45, turn up the display back to 100%, volumes upto 60% and then trigger a connection to BBC Radio 1 via Windows Media Player to wake me up. And if that fails, SPBTime kicks off an alarm at 7am which I can't ignore and wakes me up.
I pretty much leave the thing running 24x7 and it doesn't spend that much time off the charger (Charged when by the bed, and charged at work - only between times that it doesn't get plugged in). I accept that the battery will probably need to be replaced at some point, my biggest concern is the backlight wearing out.
Well, I don't really use wifi that much, but BT's always on. And it is always in stand-by mode when I'm not using it. And currently, I think I could go about 3-4 days without charging it, and using it quite heavily as it is both my personnal AND professionnal PDA and phone and I'm on the phone A LOT.
My secret (I feel like a "Barbara Gould Woman" ) ?
- stand-by after 1 minute inactivity instead of the default 2;
- Pocket Hack Master + "disabled XScale scaling functionalities" + PHM scaling engine with specific settings, among which 204 MHz as lower speed;
That way, my Athena's about 98% of the time at 204 MHz, and still feels responsive because of my scaling settings.
Thanks for all your responses!
hi all i have had to charge this phone so much its kinda doin my head in, last night i charged it and took it off at 6pm fully done and my 11pm after taking approx 30pics + 4vids(4min long each) it was down to very low life.
so i chargeed the battery fully again, and this time from 8am ~ 10am today my battery is at 77% i have done sofar
*backlight set @ 30%
*hspda ON
*Weather, facebook download every 1 hour;
*1call, 5min
*3 SMS got, 5 SMS sent
*1hours playing with phone (general settings)
*took 10 photos
*took 1 vid 3min long
from 100% to 77%,
Simple, turn off 3G. On regular GSM my phone was at 37% after 12 hours with at least 30min talking, lots of browsing, emails, texting, and 30 minutes GPS.

did u run with 3g/hspda on before and did it improve alot or not, as i use net alot and really nead hspda
TBH I doubt you are fully charging in 2 hours. The iPhone is the same, fully charging is not till the meter says 100%, that is more likely 80%.
The battery meter may also need calibrating. Personally I would drain the battery dry by running videos etc, and then charge it back up and leave it charging overnight.

i charge it alot longer till green light came on not two hours matey, it took two hours to lose that much life lol
ps. i will run a satnav a few hours should run life down and then recharge
My battery was draining fast too. I realised it was because it would stay connected to my data (mobile web for O2 in my case) and never disconnect. I only clicked on the notification bar and saw i was connected to my data for over 1 hour and half. That is a big battery drain. Don't switch to gsm mode - that would suck. What is the point of having such a high end phone and use it in gsm mode?
All I can suggest to you for the time being (until someone figures out how to have data connections auto disconnect after a couple of minutes) is to disable auto downloads for the following:
facebook, weather, mail, stocks, time sync, twitter etc.
You now have to check manually these items. Sucks i know but only way for me to not stay connected to data and drain my friggin battery
That happens to me too..I have everything set to update manually! No internet time no twitter,weather etc..And no other apps!!! And it still connecting by itself and stays this way for hours till i notice it!! Any ideas of what does it try to update??
(dont tell me the obvious ones!!)

ok sounds like a good plan matey, im currently playing a video over and over to kill my battery 0% then im going to charge from no power while phones turned off, 5% life left lol....common...
i keep getting message battery low may lose data is this true will i lose data on my fone?
on the old PDA's if you drained the battery ( <1% or something like that ) your data can be gone, its like performing a hard-reset... don't know how it is now though... propably its safe, or it turns off before 0%

You don't have to worry about that any more. A different type of memory is used. You can even take the battery out and leave it for days and all your programs and data are still there.
ok people i completely deaded the battery till it wouldnt turn on and started it charging at 15:43, its now 17:00 and still showing orange led light so i will keep checking every 15min to find out...
1) how long to charge from total flatnesss
2) how long battery last tomorrow on full charge from now to when it conks out again
will keep you updated
just for information: HD2 has a battery that needn't get totally depleted to get the full charging cycle like on older battery packs. On the contrary, the battery suffers when completely discharged. It is recommended not to leave it till the phone dies, this reduces the battery life. Charge it whenever possible. I have mine in active dock when driving in car, as well as when in office. I know the battery life could be better but well...

I would imagine video recording puts quite a strain on the battery.
Also don't forget that gorgeously massive screen runs from a 1200mAh-ish battery. I have the Xperia X1, with a 1500mAh battery. When I get the HD2 I can't help but feel there just won't be enough juice to go around.
Lower battery capacity + bigger screen = ever-so-slight reduction in battery.
I wonder whether captive or resistive screens take more power?
I'm using wi-fi at home for all data and the battery is lasting forever!
Strongly recommend tying this - see if it works for you?
ok all i have the full charge time of the battery, from complete flaness 0% life to full charge 100% life time taken
start 15:43 ~ finish 18:12 = TOTAL 3:19min.
now i will take note of all i do on the device and post results tomorrow or the next day if im lucky and it last that long lol

Also the way you charge your battery affects the charge time.
Example:
- Charging through phone using stock charger
- Charging through phone using third-party charger
- Charging using a short USB connection
- Charging using a long USB connection
- Charging through phone with phone off
- Charging through phone with phone on
- Charging through official external battery charger
- Charging through third-party external battery charger
Sometimes stock accessories are slower, others, not so. Some manufacturers refer to a "power charge", for example some Sony Walkmans. For that to work though the phone / device has to be off. Thats how they get those 3min = 3hr charge times.

Erm that's not what I advised. The aim was to re-calibrate the battery meter. All you have done is wait till the batery meter says 100%, whether in reality it's 80%, 75% or whatever. A full overnight charge would have guaranteed that 100% = 100%.
I don't see what you've done other than continue to use it the same as you already were.
I said I doubt you can get 100% in 2 hours, 3:19 isn't much more.

No he's right, completely draining the battery isn't good and shouldn't be done too often. regularly topping the battery up is the way to go.

hi i plan to monitor usage till battery drops dead and then tomorrow night or the net if im lucky i will redo the recharge test over night
I left my nexus one, which I just got on Friday, next to the TV and it was fully charged. When I came back to it about 4 hours later it had turned its self off and wouldn't turn on until I connected the charger. The battery was at 0%, anyone seen anything similar?
I have now left the phone off, connected to an AC charger and will turn it back on only when it's fully charged!
Sounds like you got yourself a defective unit.
Charger it fully then let it completely die. After it dies charge it again fully see if that helps.
Charging via the USB cable does not seem to be very efficient/reliable. Using the AC charger is quite fast, and much more reliable.
Also check the apps that are running in the background, and turn off the ones you don't need. I discovered that the animated wallpaper was quite a drain... since I switched to a static wallpaper image, battery life has improved significantly.
It has the star field wall paper, but I didn't think that would run when the phone is locked and the screen was blanked. I'll leave it to fully charge, using an old nokia charger from a n85.
So the recommendation is to run it tomorrow until it dies then charge in the off state and only turn on when it's fully charged?
I have had a G1 for the last year.

Yes, and use the charger that came with the N1.

I have the same problem. I got the phone approx. 1 week ago. before i go to work, I would have a fully charged phone. during lunch break break, ( about 4 hrs later from fully charged) its below half already! then 2 hrs later, its at to the point where it says connect your charger. Finally, off work, Phone is turned off and dead at 0% battery life. When im working, i dont even use the phone to browse or anything. just check the time on it and put it back on standby. I dont know whats wrong. Ive also rooted the phone btw with MoDaCo's rom. Any suggestions?
It was fulling charged again about 3 hours ago, not I've left it without wi-fi and with a static wallpaper and the battery is still full. I wonder if the wi-fi or the live wallpapers keep running even when the screen is off. I have checked and wi-fi is set to sleep when screen is off :-/
While modern batteries don't have the "memory" problems that cause them to lose life, they can suffer from miscalibration which will cause them to inaccurately report their remaining charge. If they report a very low charge to the phone (when this may not necessarily be true) the phone will probably turn itself off.
To recalibrate your battery, force it to drain completely. Even after the phone turns itself off, turn it on a few times more. I can't guarantee this is good for your phone, but it should get the last of the juice out. Then, when you let it charge, let it charge LONG after it reports being full, at least a few hours, to make sure it's completely full.
Sounds like something isn't quite right with your phone tbh. I have the star field wallpaper, wifi on and it's checking e-mails for 2 accounts every 15 mins.
I've also had some phone calls, been surfing the web, market and generally played around with it since I just got it on friday.
I checked the battery info on the phone now and it's been 15 hours since I charged it and it's now on 46% still. In my (limited) experience the battery seems to hold up pretty good on this phone.
That's the weird thing, it was fine Friday night and Saturday night and that was including quite a bit of playing with around
I received my phone last week. the battery was fine the first four days. after that the same problem stated above happened to me. the battery dies every 4 or 5 hours even in standby with no GPRS, WIFI or BT.
I did a complete wipe-out and the problem was gone.
I think that there were something that is draining the battery and gone with the wipeout.
by the way, i was using MCR and still using it.
thanks.
It has now been sitting for another 7 hours without wi-fi or starfield and the battery is still showing full. I'll now enable wi-fi and see how that goes. Then I'll try statfield later on. I'm wondering if the starfield keeps running even if the screen is blanked.
Actually it's showing 92% in the About page whereas the icon look full :-/
First day with nexus at work. Unplugged it from the main charge at 6:30 am at till 1:00 pm its was turned off. Made 3 short calls, no wifi, bluetooth, or gps and screen set to auto dim.
Only 6 1/2 hours is not long enough. I wish there was like a juice pack for nexus like the iphone. I could buy another battery but cannot be bothered carrying too many bits with me and opening it and changing.
Aslo charging through usb is very very slow.
my phone did this yesterday too, first time ever. I dunno why it drained so fast, something must have kept the screen on in my pocket or something.
Here's what I found.
I got my phone friday, took it off the charger and went to bed. When I woke it up was dead. What I do know is that since I'm with Roger's in Canada I don't get the 3G. I think it was searching for a 3G signal all night and that's what killed it. Try limiting it to 2G and see how the battery stands. I went a full two days without a charge, playing with it every chance I got and wifi turned on.
I'll try the 3g thing as the phone reception is poor in the room I left it. It is at 79% with the star fields wallpaper and wi-fi enabled (sleeps when screen off)

The star field wallpaper KILLS my battery even when the phone is idle with the screen off, just FYI... I switched to a default regular wallpaper and it has been fine since.

thanks i will try 2g setting tomorrow.
There gotta be something wrong with your phones or some software that is draining it.
Like I said on the previous page I use:
WiFi on
Star Field live wallpaper, with the background image nontheless
Some GPS use
Several phone calls
Some texting
Browsing the web
Screen brightness at maximum
2 email accounts updating every 15 mins
My battery still lives through the day with ease and I'm usually at 40% when I go to bed at around 1 am. I would call HTC or do a thorough check at what software is running.
edit:
Oh and I have 3G on with low reception (1 bar) where I live.
