I did, I even quoted the text from the Qtek9100's Manual and wrote it in my post, here is it again : "Some Batteries work the best when they will be charged/discharged fully several times".

Anyway, I wanted to share my experience in first place, and this suggestions I won't leave.

I have it in german language and translated it to english... I'll write it in german language here in case if anyone has the same modell (Qtek 9100) and the same language (german) to agree :

In the quick manual (Kurzanleitung) on page 8, it says the following in german :

"Einige Akkus funktionieren am besten, nachdem sie mehrere Male voll aufgeladen/entladen wurden."
[8125, K-JAM, P4300, MDA Vario General] IgwanaRob:
Yes,

some

batteries - but NOT the one you are using. It is a Lithium ion battery, not an antiquated Nickel Cadmium one, and what you are doing will destroy the battery no matter what you choose to believe.
[8125, K-JAM, P4300, MDA Vario General] yozh:
I dont know if he will kill the battery but its not necessary what he is doing, and anyway who wants to be cought with the battery fully discharged..... But Im trying what was suggested to me to see if its the data or the plugins that drain the battery, just disabled EDGE and direct push and Ill see how that goes over night....Next Ill try to take of the worldmate plug in and the spb plus plugin.
[8125, K-JAM, P4300, MDA Vario General] sunnycheng:
OK, I went to sleep @ 12 with 84% left, SPB Pocket Plus On, woke up @ 7:30, and it's down to 54%. This is pissing me off man.

Someone suggests flashing the rom again FULLY CHARGED...I guess I will be giving that a try and then tets it with out SPB Pocket Plus....

I am really depressed man...I mean...if I were to use Wifi..it'll probably lasts me 30 mins. Fully Charged...
[8125, K-JAM, P4300, MDA Vario General] Bratag:
Hasnt basically everyone said the SPB Pocket plus causes battery drain. My battery life improved greatly after i went to SBSH products.
[8125, K-JAM, P4300, MDA Vario General] Edyhan:
spb drained my battery too and i deleted it.

Someone said if you flash the rom fully charged it will improve your battery.

how does that work

thanks.
[8125, K-JAM, P4300, MDA Vario General] notpj:
yozh and thomas, we are just concerned. please do not kill your lithium batteries :D

from batteryuniversity.com http://www.batteryuniversity.com/parttwo-34.htm

"how to prolong lithium-based batteries

A lithium-ion battery provides 300-500 discharge/charge cycles. The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often or use a larger battery. There is no concern of memory when applying unscheduled charges."

avoid full discharges

it's ok to charge it often, even if the battery is not fully drained... no wait. let me rephrase that. it's RECOMMENDED that you charge often, while the battery is not yet fully drained

USB charging (charging while plugged in the computer, say, while in activesync) is one of the best feature of the wizard. i know how to turn off USB charging, but i won't tell you how ;) we are just concerned ;)

full discharges are recommended ONCE IN A WHILE to recalibrate the battery, but just once in a while
[8125, K-JAM, P4300, MDA Vario General] yozh:
Ok well here is my tests, I have spb plus running with the today plugin and worldmate pro with the today plug in. I disable direct push and the always on GPRS. I charged the battery with the USB PC charger at 8pm and then left the phone in stand by until 7:30am and guess what the battery is at 99%. Im going to do more testing, today is my bday so alot of phone calls will come in Ill wont use data, just do basic phone calls and stuff, maybe use mapolis (trial, Im just intrested after TOMTOM) and see how that goes, Ill write back later on the day.

Like I said spb plus is running, and the battery is still at 99% so I dont know if its spb.....

Oh and notpj thanks alot this proves my point even further, maybe overcharging is still a problem, but not as much as it was before, this phones should shut off charging when hit 100% and just use the external power, but I guess it still hits the battery.. Thanks notpj
[8125, K-JAM, P4300, MDA Vario General] yozh:
Ok here is the report...

I used mappolis from home to work about 45 minutes...

I got 1 phonecall opn the way too work and when I got here the battery was at 90%

Now after that I got few phonecalls and I had to go to a client I used TOMTOM for about an hour maybe hour and a half and got a bunch more phone calls and now the battery is at 69%.

I forgot to mention that I overclocked the little CPU to 240mhz. Ok I will report later on the day.
[8125, K-JAM, P4300, MDA Vario General] Bratag:
Looks better.
[8125, K-JAM, P4300, MDA Vario General] Thomas1234:
Thanks notpj for this interesting link. Now what I understood from it is frequent full dischargs - for lithium-ion - isn't recommended, but Several partial discharges with frequent recharges are better for lithium-ion. And recharging a partially charged lithium-ion doesn't damage it. It is recommended to keep the battery cool and avoid the heat, which means leaving it long time on the charger although it is full charged cause problems.

Well I sent e-mail to Qtek Support, and asked them about the Battery, they answered that nothing of the mentioned above will harm the battery, neither discharging the battery fully nor recharging it while it is still charged. And they even mentioned that leaving the battery long tim on the charger doesn't damage it. Well their answer sounds positively. But I think the link posted by notpj abov is more trusted IMO.

Ok well, notpj can you please tell me how to stop the charging when the Wizard get connected to the PC using USB ? because I really feel bad when I charge the battery while it still has more than 50%, I appreciate that in Advance ;)

And yozh, nice improvement.. The result is really positiv IMO, from your test, I can understand that connecting with GPRS drains the battery quickly. I think everything is clearer now.
[8125, K-JAM, P4300, MDA Vario General] yozh:
Just an update...Got bunch of calls since my last post didnt really use the phone for anything but that. Im now at 58% which I still think is good specially that this thing is overcloked :). Ill report more later. Thomas1234 so they said nothing harms this battery ? I guess thats good, dont know if I belive them but thats good
[8125, K-JAM, P4300, MDA Vario General] yozh:
Ok here is another update I had 18 phone calls today, and some were 4 -5 minutes long and the battery is now 52%, so I come to conclusion that its not the spb plus its really GPRS with direct push or maybe mail2web.com free exchange account that makes it sync more often then it supposed to, that drains the battery. I dont know if I can just leave it over night with out being charged, I cant be left with out a phone tommorow. But Ill let it run all the way until I go to sleep Im sure Ill get more phone calls by then.. Ill write more later..
[8125, K-JAM, P4300, MDA Vario General] notpj:
@thomas, you still want to turn off usb charging? like we all suggest, it's better to turn it on. don't feel bad, it's better for your device that it charges when it's on activesync while the battery is still at 50%

but if you really insist, the answer is on this forum somewhere. think registry hacks
[8125, K-JAM, P4300, MDA Vario General] yozh:
Well 23 phone calls for the whole day and the battery now is at 48%...... Like I said before the only usage besides the phone was the use of TOMTOM and the Mappolis(or whatever its called LOL)for about 2 hours all toghether, this too are very heavy on the power because the y leave the backlight always on and the processing of the directions and constant use of the bluetooth to send data from the GPS. So I think its not bad Ill leave the device not charged over night and see how it goes. Friday I will turn on GPRS, but not the direct push and see what happens then. BTW spb plus is running with the today plug in and worldmate pro is running also....
[8125, K-JAM, P4300, MDA Vario General] notpj:
i tried a hard reset and installed ONLY spb pocket plus, but turned off the top bar battery meter and all the meters in the today plugin. after a half day, my battery life is halved too. i'm performing another hard reset in a while... for the fifth time in one month
[8125, K-JAM, P4300, MDA Vario General] yozh:
Well its morning and the phone was in stand by all night I now have 43%, so its been about 36 hours of mixed use and standby and I have just below half the battery left, I think thats pretty good.

I got a question for someone that uses SBSH products, I hear good thing about them, but do they have the X taht really closes things like SBP plus and that function to be assigned to a button, like now Im using the PIE button to as the close function of SPB. Some get back to me on this THX.

I will report later on the day with more usage....
[8125, K-JAM, P4300, MDA Vario General] Tezcatlipoca:
I use SBSH's iLauncher, Pocketbreeze, ContactBreeze, & PocketWeather.

iLauncher is similar I guess to SPB Pocket Plus, although doesn't yet have a proper close button like Pocket Plus, WisBar, etc.

So, what I use for that is water's "Smartskey" - very good little free app, it gives a proper "close" button, & lets you remap various keys. See http://xdaforums.com/viewtopic.php?t=41060
[8125, K-JAM, P4300, MDA Vario General] yozh:
Maybe I should use the smartkeys, I didnt know it had the proper close button, I just tought it remaps keys..
[8125, K-JAM, P4300, MDA Vario General] Tezcatlipoca:
Yeah, it maps a hold (not press) of the right-hand soft-key to be "OK/Close", & you can set a value in the ini file so that when you use it to Close, it actually closes rather than minimises.
[8125, K-JAM, P4300, MDA Vario General] yozh:
Thats diffrent I want like the X so I can do it with the touch screen as well as the buttons like the spb does... But thats still kewl.

BTW got couple more phone calls used the TOMTOM for about 30 minutes and now the battery is at 26%, I think thats retty good, I hope I finish with a client before battery runs out so I can go the the car and charge it :
[8125, K-JAM, P4300, MDA Vario General] notpj:
someone tell me what to do!!

i just did a hard reset on my wizard. nothing was installed and after a day, my battery was drained. no battery-life-sucking programs here...
[8125, K-JAM, P4300, MDA Vario General] yozh:
notpj perhaps replace the battery ?
[8125, K-JAM, P4300, MDA Vario General] Edyhan:
don't use the brightest light(try the mid)

and turn the option that says"turn off device if not used for 4-5 minutes'

you should have 2 days or so.

if its still the same ask for a replacement
[8125, K-JAM, P4300, MDA Vario General] notpj:
wah. the backlight is in the lowest setting and it's set to turn off after one minute. i am probably going to ask for replacement
[8125, K-JAM, P4300, MDA Vario General] sunnycheng:
Guys, I have fully charge the phone @ 10:45 today using my NEW REPLACED battery. I have received two calls, duration not over 2 minutes total. It's 2:40 right now, and it's down to 90%. THis just can't be right can it? I only have batti installed. I am not going to bother testing the battery with no programs install, what's the point if I can't install most of the useful programs on it right? So I am definitely going to try to get a replace ment and see. But I am just really curious what is causing this problem on some of the wizards...... is it possible that it is indeed a hardware problem? (not the battery though)
[8125, K-JAM, P4300, MDA Vario General] jt_armstrong:
Sorry guys but this might piss a few of you off a little. I did a bit of an unscientific test last night, I fully charged my battery then disconnected it at 1am before going to bed. I have just checked it and 12 hours later it is still showing......100%.

For the record the device goes into standby after 1min, wireless and GPRS were both on although the WiFi will have switched it's self off when the device went into standby. I received no phone calls during the test. It is configured to poll my email servers every 15 mins. I run 2 main pieces of software (Battery Pack Pro and Journal Bar) BPP constantly polls the battery for charge status and JB uses the GPRS link for various updates to the weather and news etc. JB is set to update the data every hour and whilst I can't prove that it has held to that frequency, I can say that the data is upto date as per the web sites where it gets the news feeds. The GPRS link has shifted 10.1 Mb of data so it certainly hasn't been sitting idle. I might just let the test continue just to see what happens.

For the record this is exactly what I expected. My battery nomally lasts for ages.
[8125, K-JAM, P4300, MDA Vario General] yozh:
jt_armstrong this is imposible, or your battery metter is lying to you..... if it transfred that much data the battery had to be drained atleast a little, so I would suggest to soft rest your device and see what the battery metter will show now.. Good luck.....
[8125, K-JAM, P4300, MDA Vario General] jt_armstrong:
Yozh

Have just done the soft reset, both the indicator on Battery Pack pro and the system indicator are still showing 100%. This doesn't surprise me at all. When I upgrade frm the stock T-Mobile ROM to 2.17 I noticed this and thought the battery meter had a bug. I think it went 18hrs before it started to drop. I haven't tested it like this since I upgraded to to 2.21 but I hadn't noticed any difference to the battery life. I know I have a good solid battery as I normally only need to charge up every 3 days or so.
[8125, K-JAM, P4300, MDA Vario General] yozh:
Well then you must have a magic battery :) if you doing this much data transfers and your battery does not drop then it MAGIC :)

If I dont use data GPRS and WIFI the device will need to be charged every 3 days also, but with data transfers its much less then that :(
[8125, K-JAM, P4300, MDA Vario General] jt_armstrong:
Nothing magic that I can see. If you think about it 3 days is no big ask and a device such as this that doesn't last three days of "Normal" use is going to be pretty rubbish in the hands of a real user. My Nokia 9500 lasts over a week with a low call rate so this should easily do 3 days... By the way the meter is now showing 94% so the slide has started to register
[8125, K-JAM, P4300, MDA Vario General] sunnycheng:
I agree with with Yozh, there is no way this thing can last 12 hours running GPRS with data transfer, and has no drop in percentage in battery life at all. well I am not saying you are lying, but may be it really is registering wrong. At what percentage do you usually charge the phone at?

BTW, I just got a replacement phone UK mini s, using the OLD dopod rom, and the battery issue still persist...going to try to update the rom and see what happens. cost me 90 usd man..
[8125, K-JAM, P4300, MDA Vario General] jt_armstrong:
I use Battery Pack Pro and have it configured to squawk at me when the battery drops to 25% thats normally when I charge it. Outside of that it will get a boost if I need to sync my calendar which is typically once a day but it's unlikely to be hooked up for more than 10 mins. By the way the battery meter is currently at 88% having been last charged 18.5 hrs ago. It has had two soft resets (both to see if the battery reading changed - which it didn't), still no phone calls but has continued to keep my news feeds updated. Not sure how much data it has shifted now due to the resets. BTW I don't ever use BT.

For the statiticians among us, the battery meter registed 100% 12 hours after having been charged. 18 Hrs later it now shows 88%. That is 12% in the last 6 hrs but nothing in the 12hrs previous.... I think the issue is that the output from the battery meter is not linear. It might be interesting to plot the battery reading over time to see how it drops off...
[8125, K-JAM, P4300, MDA Vario General] sunnycheng:
Ok, I have just tested out my replaced O2 Mini S, charged it full and patched it with Latest Qtek Rom, Fully charged @ 11:00am, and warns me of Battery Low @ 11:30pm with 5minutes of talk time, that's all, the rest of the time was in standby. This is my 2nd Mini S, what could be wrong?

I have tried it with two batteries and they are the same..
[8125, K-JAM, P4300, MDA Vario General] jt_armstrong:
sunnycheng

Not sure what to suggest, 12 hrs run time is on the wrong side of useless. For the record I have kept my test running and my battery is now showing 62%. It hasn't seen a bit of charge for nearly 36hrs. I've had a couple of short phone calls now as well. GPRS is still updating as expected.

Just to rule it out can you check the make of your battery incase more than one manufcturer is being used. Mine is made by Sanyo model number WIZA16 rating 3.7VDC 1250mAh.
[8125, K-JAM, P4300, MDA Vario General] xboxhaxorz:
Yep, i updated my rom with a fully charged battery and i still have crappy battery life with mine.

I cant get it replaced through t mobile.

I hate you with your super battery, ill give you 50 bucks for it. lol

ATTENTION:

Why dont we post which Wizard we are using be it, cingular, tmobile, qtek, or the imate.

Maybe this has something to do with the issues.
[8125, K-JAM, P4300, MDA Vario General] notpj:
yeah. i'm using the DOPOD 838, a WIZA100. battery life sucks. it was ok once in my life. now, even after a hard reset, battery life sucks
[8125, K-JAM, P4300, MDA Vario General] xboxhaxorz:
T Mobile MDA with updated cingular rom
[8125, K-JAM, P4300, MDA Vario General] sunnycheng:
Guys, I don't know if I am right, but I might have found the cause to this battery drain issue (hope we can fix it),

I saw this program made by a member on this forum "b_timer"

http://xdaforums.com/viewtopic.php?t=45168&start=25

well, it simply records process time (when the cpu is processing), and Idle time (when you press the power button). But apparently, my result is, even if I had it on standby the whole time, the Idle time is still zero, but processing time keeps counting. So may be that's the reason for the battery drain? Can some of you also try this software (especially those who are having battery drain problems) and discuss the results?
[8125, K-JAM, P4300, MDA Vario General] jt_armstrong:
sunnycheng

I downloaded the "b-Timer" program and although I have only had it on my device for about 30mins it is showing that it was in standby for 22 mins which is roughly correct. If yours is always showing the CPU is in use then I do believe you will have found why your battery is draining.
[8125, K-JAM, P4300, MDA Vario General] jwzg:
Re: New ROM

I about shot my water through my nose!

Classic!
[8125, K-JAM, P4300, MDA Vario General] sunnycheng:
NOTPJ, other people with crappy battery life, did you guys try installing that software and test it? Just want to know if that's the cause, then may be someone can help us out here?

Thanks.
[8125, K-JAM, P4300, MDA Vario General] Edyhan:
mine was very bad but after i get the replacement and turn on the option says turn off the device if not used for 5 min.

really changed my battery life.now it lasts about 2.5 days
[8125, K-JAM, P4300, MDA Vario General] notpj:
@sunnycheng, i'll try that app out. btw, what device do you have and what ROM version?

i think you may be right on this one. i notice that my battery is warm all the time

will tell the results later
[8125, K-JAM, P4300, MDA Vario General] sunnycheng:
I just had my German Version O2 Mini S replaced by a UK Version. Using the newest O2 Rom on the FTP.

I notice somthing today, for the first time, my phone actually had the idle time counted for 4 hours..after it was charged....so it was reallly on standy by for those 4 hours, and guess what? After four hours, it still had 100 % on it... which did not happen before in my case.. but then..after turning the phone....it did not go on standby anymore....so back to beginning... awaiting other ppl's result.
[8125, K-JAM, P4300, MDA Vario General] notpj:
i think i found the solution to my problem. all these time i was on vacation, where my network couldn't reach me. i let the GSM radio on all these times. thankfully, bycastro pointed out that my wizard could be draining battery because it kept on searching for a signal.

so i turned radio of at got ok results. didn't really check how good the improvement was.

now that i'm back from my vacation, where i finally have a signal, i guess i could say the battery life is normal. although i don't know to what extent.

if i don't get 2.5 days under normal usage i won't be contented

sorry sunnycheng haven't installed the app that counts idle time yet... but it looks like your problem is solved too
[8125, K-JAM, P4300, MDA Vario General] jpolster2005:
why dont you just charge your phone every night while you sleep and only worry if it doesnt last a full day? I get up at 7:30, take off charger, put it back on about 10pm and i never even have to check my battery power. all you people saying "oh yea 5 days, 2 days, 3 days" thats crap! I have never gotten that much out of a phone! Not my N-gage, my Tmobile Pocket PC, my h6315, my black berry, my treo, non of them last that long if i forget to charge! i even had a ppc4100 for a while.... that was dead by 7pm! most normal people charge there phone every day!. and dont care about 4 days! I cant believe how picky you are being considering the low cost of this device
[8125, K-JAM, P4300, MDA Vario General] Halfhoff:
Thanks for the tip!
[8125, K-JAM, P4300, MDA Vario General] sunnycheng:
The point is, this is abnormal, if you just leave the phone on standby doing totaly NOTHING at all, and you have to charge it in around 12 hours, but KNOWNING your phone shouldn't behave this way. That's a big problem if you put in a few hundred bucks for the phone.

NTOPJ, My battery problem still persist. If I can't find the fix for this, I'll have no choice but to sell it.... Can you please install the program when you have time and see? Thanks. THe fact that you turned off radio signal should lengthen your battery life, that's the only reason.
[8125, K-JAM, P4300, MDA Vario General] notpj:
sunnycheng is right. we are complaining about it because it is abnormal. the device is also not low cost (not low cost for me at least) AND the longer the battery lasts, the less number of times you have to recharge it. take note that Li-ion batteries have a set number of recharge cycles. if you have to recharge your battery every night, then for sure your battery wont last that long. batteries aren't cheap either (not cheap for me at least, again)

@sunnycheng

sure man. i'll be installing it right now. i just have to check if my uptime is correct right? if it counts that it is off when it is really off?
[8125, K-JAM, P4300, MDA Vario General] jpflaw00:
suggestion

I really suggest people with the battery drain issue to download the program and see if your phone goes idle during standby.

http://xdaforums.com/viewtopic.php?t=45168&start=25

If you read my post it will state that my idle time only ticks when my memory card is not in the device. I really wonder if this is a voltage issue with the memory card, as I have read this somewhere else stating this fact.
[8125, K-JAM, P4300, MDA Vario General] jpflaw00:
Try to pull out the card then go into standby for more than a few seconds. Wait for a minute and see if the idle time changes. I believe that the Wizard has a delay when going into standby. This can also be seen with overclocking. If you go in and out of standby quickly, smartkey will not be able to clock your settings at the given speed correctly, and it will default back to 180 (195 mhz). Really, if you want to know if it's your card try to use a different brand and compare the battery life. I would do this, but I don't feel like spending anymore money on another memory card. Let me know your results.
