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.
I may be wrong, but it seems to me that battery goes down qute fast in opened state (when display turned up as normal pda)...
THX
well, yes, the backlight chews battery, just like on a laptop. Turn down the brighness a bit (i use on the 2nd notch) and you will get more battery life.
Also, you do not have to have it "on" all the time to receive calls etc. as it will bring itself out of standby when a call cfomes in.
Remeber, PDAs do not have a massive batterry life, and with "normal" use, you ca expect the exec to be at around 50% battery after a days "average" use (a couple of hrs wed surfing, 30 mins calls phone on all day)
Now, I know that it depends on what programs are running, like... whether you have any minimized or in the background, but on an average 1500 mAh/3.7V battery... what is the amount of use time that one can expect...?
Let's start a thread on this subject... listing the type of battery, approximate age of same, the names of the files/programs you run & use in a given day, and the amount of hours of overall use you get before you have to recharge or switch it over to a new/fresh battery. This way, we'll all have a better idea as to what programs really drain the phones, such as when you leave the WiFi and/or Bluetooth "on" all the time - waiting to be used (a sure guarantee to have a dead battery in a matter of hours).
We can subtitle this one under "The Cost of Staying Connected" (not including air-time charges or monthly fees).
i think my battery life is terrible... but its understandable. usually i run wifi and phone all day long.. the only reason i run wifi on all the time is because i have a feeling everytime i don't... somehow i get charged for using evdo (from bell in canada)... but i dont?? its really weird because i used to always get these random charges.. but ever since i kept my wifi on all day everything is all good. i have the original battery that came with my ppc 6700.. and i use the phone around 40-70 minutes of talk time. no real apps running but a few games of solitaire here and there. but if i were to talk non stop it only seems to last like 1hr
my battery life is like 10 hours and i always have to charge it when i get home from work or school or ill be doomed the next day
Since upgrading to WM6 (thanks helmi), my battery life has found NEW life. I used to have to charge it everyday: no wifi, 50% brightness, screen off in < 1min, etc. Since upgrading, I can run it at 100% brightness, screen off in 2min, and I don't have to charge it every day.
This is with the factory battery, and an eBay replacement sometimes used.
always running: freestyl (flashlite), sms threader, mbutton
phone is usually locked with s2u2
most use it usually gets is me checking the time
update rom from verizon, .net 3.5
ever since i updated the rom, it seems like i only get <24 hours per full charge (battery purchased less than a month ago)
w/o wifi or bt i get about 3 days however it depends on what version of windows are you running have you guys updated to the new 6.1 or 6.5 biulds?
My battery life its very short but, i use my apache with core play at my car with my kids plus the wifi, and blue with hand free, soo i've to conected every day, and i'm use 2batterys
original battery... i got 3 days on standby.. and 2 days in normal call usage...
but
with wifi my battery gets drained to the bone in 40 minutes LOL
thats all =D
About twenty minutes. I know I need a new battery >_>
... that and that I'm surprised I've got over 240 hours clocked in the lifetime call timer.
Using a 2600mAh 3.7v Battery
I had my extended battery for about 2 months now.....
TCPMP:Battery life is close to 5 hours on the lowest brightness level using headphones & on speaker mode I get about 3 1/2 hours.
Making Calls: I sometimes spend about 2 to 3 hours on the phone & that leaves the battery to about 70% or 60%.
Wifi: I don't use it for a very long time, but when I do it could be about 1 hour and that can leave my battery to about 80% to 70% when done.
Videogames: I use mainly the Morpheus(emu) usually about 20 to 30 mins and only seems to leave it close to 90%..
With random use I normally have to charge the battery every 2 or 3 days... I play with the phone quite a bit tho! Mostly text messaging (turning it on & off about 20 to 30 times daily).
With my 2 normal batteries? I think they need to be discarded soon lol!!!!!!! Wifi will deplete them(each) in about 4 or 5 mins tops!!! TCPMP about 10mins(screen on at its lowest with speaker) & 15 mins max(with headphones & screen at its lowest brightness)... Phone Calls? about 20mins tops(with the screen turned off)!!!!
So.... I strongly recommend the extended battery on Ebay for about $22(shipping included) so that you can enjoy the phone alot more!!!
I try not to keep the phone on the charger until the battery has depleted to about 20% when the warning comes on and fully charge it always!
Samsung GT-T5800. Android OS 2.1-update 1, I5800XXJH1, Kernel 2.6.29 root SE-S603 #2.
The problem:
1. Battery till 50% discharges normally - about 10-15% per day, but after 50% it immediately shows 15% and asks to connect charger and phone switches off very fast. actually no chance to mane even emergency call. No 40%, no 30%, no 20% in battery level.
2. When connect phone to charger - battery charging level immediately set to 80% or every ~10 seconds: 50%, 60%, 70%, 80%. After that phone charges about 1,5-2 hours till 100% and after about 1-2hours it asks to disconnect from the charger. Battery temperature during charging and after it: 31-33C.
After 3d 8h 40min. (~80hours using applications: Battery booster and Memory Booster, no 3G) of battery usage phone switches off.
Battery usage was:
Android system: 61%
Cell Standby: 19%
Phone Idle: 12%
Bluetooth: 4%
Voice calls: 4%
Time from 15% to 5% - 15 minutes with no using the phone. Battery's temperature 20C, Voltage: 3588mV Phone switches off. I have tried 2-3 times to switch on the phone to make battery more empty and finally switched it on and at the same time connected it to charger.
Here is the interesting charging time line after phone died and was switched on to charge it (sorry - no in seconds):
0:00 - 1% - 20C/3588mV (temperature/voltage)
0:01 - 3%
0:01 - 5%
0:01 - 15%
0:02 - 15%
0:03 - 30%
0:03 - 40%
0:04 - 30%
0:05 - 15%
0:07 - 15%
0:09 - 30%
0:12 - 40%
0:14 - 30%
0:15 - 15%
0:16 - 30% - 28C/3698mV
0:18 - 40% - 28C/3718mV
0:20 - 50% - 28C/3730mV
0:21 - 40% - 28C/3727mV
0:23 - 50% - 27C/3728mV
0:36 - 60% -
0:36 - 50% - 26C/3769mV
0:37 - 60% - 26C/3774mV
0:59 - 60% - 26C/3807mV
1:24 - 60% - 26C/3807mV
2:06 - 70%
2:07 - 80% - 26C/3906mV
2:44 - 90% - 26C/3971mV
3:18 -100% - 25C/4101mV
4:03 -100% - 22C/4184mV - Asked to disconnect the charger.
After this charge GT-I5800 (with no any software changes) stoped to show 50% to 15%, but 30% disappears fast to 15% (it means one short call).
Possible that battery issue reason is that (I think) phone was charged partly switched off and partly switched on.
Maybe there are some battery level controlling OS software bugs, I do not know.
Is it official bug or issue?
Or some guru can comment that battery level issue? I saw I was not first user having it.
should be from the firmware
it seems this happening to all
Well i also have exactly the same issue...
I have observed that when i make/recieve a call the battery voltage decreases greatly because of which the battery also decreases and after sometime the battery voltage comes back to normal but NOT the battery.
My battery also drops down from 50% to 15% or 5%.....It's really very annoying...
I think that this is a frimware issue but i am not sure..I am scared that it could be a hardware issue...
Well i have mailed Samsung also regarding this issue so that they fix this issue in the next frimware upgrade and hope others also do the same so that we have a better chance of this bug getting fixed.....!!!

And when I switch off / on the phone then it shows probably correct vallue. For an example. It shows me 15% and after restart it is 60 %. What a stupid bug - I've never have this problem with any device before. Even phones 10 years ago were able to show correct battery status. I think this problem was also with original 2.1 android firmware.
Can someone who has upgraded to froyo pl. confirm that this issue is resolved in the new firmware?

yes, in JP9 / froyo is still this battery problem. When I switch on / off the phone then it's ok. Does someone resolved this issue please ?
My issue still exists. Froyo did not help. Also I can't understand why does one time on charging battery becomes hot, another time -cold.
same for me, and today i charged my phone and after charging just put it on my table after 1h i saw that there are only 80%. Didn't see this on other firmwares
Same here. I thought it is because of my battery manager widget which I had installed, but un-installing/master clear also did not help. Looks like it is major problem. Moreover, few of the battery widgets mention that in some devices they report 1% level battery change, but in Samsung I5801, it will be 10%.
what about this issue at JPA ?
when you was installing JPA did you hard reset your phone ? (factory settings)
If yes which application do you use for restore all of the datas and settigns ?
Yes, it was done. Hard reset seems is not related, and did not help.
Same problem here...
Since built in battery meter is not accurate at all Im using custom one but problem remains.
might fix battery issue.
might work...saw it for Epic 4g and gave it a shot (as its Samsung too). Some sites say LiON do not have memory like NiCd did but somehow it worked for me. Now I stay on 100% for 5hrs or so. lasting 2 days with 45mins call time and some Wifi use. Like today charged full 100% at 9AM and now its 2230 and I have 80%.I have switched off a lot of things. See below.

Above needs to be done once only. If it doesn't work then go to service center. Remember battery has 6 months warranty only so be quick and try above on new battery.
I also run LauncherPro instead of stock. Disabled data and enable when out of AP range (only use Wifi when needed and have an AP). Background data/synch is always off unless I use market. All apps are set to never except Gmail. Use K9 Email too and ATK. Am on DDj6 FM. Have removed a lot of apps, foursquare included and run 2 screen with LauncherPro widgets only.
Settings to switch off are here.

As long as I know li ion batteries doesnt have the memory effect but they still have to be recalibrated from time to time, lets say once a month. That means dont charge the phone until it goes off and then charge to the top.
I wasnt willing to wait for 11 hours for phone to charge when I bought it and after few days I ve notice that battery last very short. After that I ve performed the full cycle (drain to the bottom - when phone turn itself off, then after few minutes turn it on, wait until it goes off - repeat few times until its completely off then charge it fully - I usually turn off the phone while charging ).
As long as I know all modern devices like phones, notebooks etc shut down before the battery is completely drained because they want to have safe margin of the battery power because of, as long as I know, when li ion batteries become completely drained then could be damaged completely so you cant recharge them again. Anyway with that "turn on then its drained" I believe that I use the battery more than normal and that phone will recalibrate to the new situation figuring that battery have more voltage than phone "expected".
Anyway with few recharging cycles like those I ve described above I can use the phone now for a 2 days with moderate usage...
That 50-15 problem still exist but 100% period last quite long and also phone can be used a long time from the moment battery reach 15% ...
Try doing it the other way round!
Keep your device on constant charge or at least as much as possible for 10 days from new and you should have now problem.
I have run tests on Lion powered devices for the past 5 years and I have never had to "calibrate" once.
My battery usage is always consistent and seemingly accurate.
And this method encourages max power from the battery.

i just flashed my I5801 with Froyo (XXJPB and then XXJPA), but having very low battery back up, can anyone advice something which can help boosting the performance of the battery? Please help.
Hello, Im noticing that the battery charge is too short.
I disconnected it from the computer (battery at 100%) at 23:00. Inmediately put it on fly mode (all services disconnected, low battery consumption). When I wake up at 9 o'clock, the battery was like 60% (and disconnected fly mode). Now, at 11, the battery is like 40%...
Yay, I usually charge it every night... I don't want to charge it twice/day.
I don't know if trophy have now battery problems or is just wp7.
Anyone with the same problem?
If you just got your phone, I think the battery was not run in yet. I have the same problem for the first 3 charge. Now battery life is slightly better than my old omnia 2 which last me 12-14 hours as I am a heavy user.
It have like 15 charges. It usually takes longer to uncharge, but not today, I will test it more days.
Thanks for you reply.
Sounds like there could be something wrong with it. Mine is a lot better than the HD2. I'm not a heavy user, but I get like an hour of music/radio on the way to work, then a few calls and SMSs during the day, an hour of music/radio on the way home - and it's still on like 70% when I set it to charge before bed time.
Update: seems location services cut the battery life in half. MS needs to do something about it to make it more efficient.
battery ??
How can i check how many % of my battery left
I've charged my Trophy about 4 times and the last time i overcharged just like in formating a battery ( i know the bqattery in Trophy doesn't require it but I can't hurt can it??).
The last time I charged it was on the new years eve just before midnight between 22-23. Now the battery has been showing the "critical battery mode" thingy for about two hours. I admit that I am not a heavy user however per day I make couple of phone calls, I make a few SMS and use the 3G mobile network/ WiFi(if available) to check internet write a mail, Facebook etc. and about 30 minutes / per day of music...( need to say that I don;t use the standard phones which came out of the box but Seenheiser 515HD model )
I have set the 3G and mobile data etc off, the brightness level to automatic, set the theme to dark etc. to save the battery as much as I can.
