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,
San
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.
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.

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
Since applying the 1.47... OTA, I can literally watch the battery drop minute by minute while the phoe is active.
Within the first 1 minute of removing the phone from the charger the Battery Status Pro reports the charge droping from 100% to 97%. That's a 3% drop in 60 seconds.
Within the first 3 minutes of active use BSP reports the battery drops to 93% charge. That's 7% loss in less than 200 seconds of use.
Now I'm not saying BSP is 100% accuerate but I expect it's not too far off.
Battery life with the Evo has never been phenominal but this seems rather extreem. The drop seems far faster now than when running the 1.32 release. And... while I am in a 4G enabled market, this is with 4G disabled and the phone running purely on 3G with no flickr, twiter, facebook or other feed widgets running and autosync disabled for all of them.
When I look at Battery Use under settings / About Phone / Battery the Android System is by far the largest user of battery, nearly twice the next closest user which is Cell standby.
Am I the only person experiencing this?
The phone was doing this before the 1.47 OTA, it's a problem with charging the battery in the phone. It does not charge properly for some reason and it will drop all the way down into the 80's within an hour of unplugging it. If you get an external battery charger and use it to charge the battery the phone will stay on 100% for an hour or more...
Have you removed the HTC people widget from home screen? The day I removed that was the beginning of decent battery life. Also try turning off the phone when charging - seems to work better that way.
I would try charging to 100%, unplug, wipe the battery, plug it back in again until the light turns green and try again and report back.

I wondered if it was the powered off portion of that battery trick that was doing it. Hmmm. I'll have to watch. Is there any link/source on the idea that the phone itself is not working so well at charging?
Out of that voodoo on the getting better battery life the only thing I could come up with was...-charges better when off, - you need to charge for a bit while on to reset the battery indicator, - and charge a bit while off to top it up.
So I was leaning toward it being a charging thing and not a battery thing...would like to see any technicals though and not just my guessing.
People widget has been long gone.
I gave the charge it with the phone powered off thing a try. The device was down around 80% charged when I powered it off and plugged it in. In about 5 minutes the charge indicator turned from amber to green as if it were fully charged.
I can't believe that the battery charged 20% in 5 minutes.
This leads me to believe that the first response is correct. The battery simply isn't charging fully in the phone. I believe I'll look for an external battery charger and give it a try. See if it makes a difference.

Seriously, try full-charge, wiping your battery data and then shutting it off and 'topping it off' and reevaluate the situation.
EDIT: The "topping it off" thing is all voo-doo as far as I'm concerned. I just do it to be safe, though I'm pretty sure it's ineffective.
I screw with my phone so much, so much flashing/restoring back and forth while on charge, between
charge, car charger, USB charge at work, wall charge, flashing again, kernel swap, restore back again...etc etc etc...that if I don't wipe my battery once I hit a full charge there is no way I can trust that meter to do anything more than change colors. I do it every few days when I notice the meter isn't being trustworthy.
If this doesn't work for you I'd say you probably have a bunk cell in your battery, and failing that your phone just might not be charging well.
Also, charge with the wall and not USB. USB takes forever. And 20% in 5 minutes isn't TOO far off if you are plugged into the wall and getting full-power charge. Maybe 10-12ish minutes, unless you were timing it very specifically....
I just got my bricked replacement. Here is the data from a 100% charged battery usage up time 18:13 .. Awake time 15:27 the battery is at 87%
funny im getting 20 + hours a charge after the OTA
with heavy usage
So I noticed something weird about my phone. When you go to menu>settings>about phone>battery usage, it tells you when you last unplugged well my phone does not seem to reset that timer always . I can plug it in for a couple hours and take it off charge (battery level does increase) and it will still say i have been unplugged for X amount of hours. Anyone have this issue. Never happened in any of my previous android phones. Btw stock Nexus S 4g, Im truly stumped on this and looks like no one else has this issue.
I think it only resets once the battery becomes fully charged.
Thats what it seems like its doing but i know my previous android devices would restart the timer when i would plug in even for a second or when i turn off my phone and turn it back on granted my last phone was a Epic on 2.2 so i don't know if that makes a difference. This one only seems to do it at a full charge like you said hmm interesting. Other people having the same results?
I've seen it before. I once had it going to five days. I tried restarting the phone, but didn't work. Had to clear battery stats in recovery but like you said you're stock.
yes, since gingerbread, battery stats reset only if you keep charging until 90% or more. I have a nexus one and with 2.2 it reset every time, but not anymore.
Okay good to know its just a gingerbread 90% thing because i thought something was messed up. thanks!
Did you used the USB-charger? Then it won't reset the timer.

Yes I am using the Stock charger in my PC or plugged into the wall plug it wont reset it until it hits a high battery charge level.
Soo i fully charged to 95% last night and when i took it off this morning the timer still didn't reset hmmm at this point im tempted to go around root and clear my battery stats
No one has mentioned the battery usage graph (hard to notice, but there behind the "Time since last charge" message on the top) which shows battery usage over time since last full charge, including interim partial charges as hills...

I am now getting this problem too where it doesn't reset, even after it charges overnight and hits a high charge amount (94+%). Did you ever figure out a way to get it to reset to 0 sec on battery without resetting battery stats?
Hi!
I'm suffering from a strange battery behavior lately: This morning, after 9 hours charging, I woke up to a 75% full battery, when usually, it should get 100% charge overnight. Previously, I had an accidental power off by power depletion, some hours ago.
Now, I'm trying to charge the phone but it seems to charge way too slow.
Finally, I decided to power it off and let it charge without any possible drainage. In the moment I powered it off, I was prompted with the battery icon displaying 96% charged...??!?!?!?
I don't know if either the battery is broken, the rom is reporting it wrong or what.
I usually play Ingress, which drains the battery like crazy, and I'm usually browsing the internet and reading twitter on my phone, so, at the beginning I thought I just needed to keep my hands off the phone for a while and let it charge, but after that overnigt 75% charge incident... I don't know what to think.
ROM is Carbon ROM KK, kernel is AK without any tweaks, no undervolting or anything... any advice?

Don't over charge.
Yes, I have the bad habit of being unable to see my phone drop the battery level under 60%. At my job, I always leave it on a qi charger, regardless of it being full or empty. Perhaps I have to take the habit of letting it drain until 30% or so, and start charging then.
Other thing I can do is limit the charge level top, tweaking the kernel setting via synapse..... Could that be a good thing?
After starting the phone, the battery level seems to be OK. It's 87% now and it's draining quite slow, compared to before. I guess I'll have to start treating my battery better.

Some update: the phone was bought on March 2013,but the battery has a build date of December 2013. I think the guys that repaired the phone swapped the battery for another one and left me with a defective one.
