hi every one i have recently perchest the Qtek 8500 and i see that the batry gose very shortly driy (2~3 days) now i wonder if its posibol te put out the green flashing light under the externel screen so that wil help to give the batry charg loger life. so if thair is an aap. or an program for this jub please help me.
with many thanks in advance.
There are several applications which let you disable the led's on phone's.
You can even do this yourself in the registry (if you know the path).
Problem is, I don't think it's been done on the Qtek 8500 phone. Most other phones work fine with the disabling software/registry, but not the 8500.
Anyway, it's not like the led's take a lot of power. I think it would save perhaps 15 minutes in 3 days, tops.
Things which do take 'a lot' of power is the external screen (if it's on), Bluetooth, having files/applications open and the SD-card.
If you turn everything off and get rid of the SD-card it'll probably save another few hours.
But in short, I think 2-3 days is quite general for this type of phone. It's not a Nokia, Samsung or Sony Ericsson 'regular' phone which have stand-by times of several weeks.
The current WM devices tend to have a max stand-by time of 3 days I think.
2-3 days is very good. My qtek 8500 without more than 20-30 minutes calls it stays on only a day, a day and a half most. What battery you have?
It's a LED, so we can say that it uses almost no power at all. Not even the 15 minutes in 3 days LOL

One LED does actually cut 50 percent of your phone standby time while permanently on. That's why the WM dev guys let them blink shortly in longer periods.
Let me quote WM's Mike Calligaro at this topic:
"..A typical LED, while on, burns 5 mA of current. Remember that the entire phone in standby is burning 5 mA. Turn an LED on and leave it on, and you'll cut your battery life in half. Fortunately, we don't usually leave LEDs on. We blink them. Typically, the blink rate for a LED is something like 0.2 sec on, 1.8 sec off. Since that results in the LED only being on 10% of the time, overall it just burns 10% of its 5 mA, or 0.5mA. .."

As less the phone consumes idle as more significant the LED power consumtion becomes. So the best would be to switch the LED off completely.

huh, that changes everything I've ever learned..
His stats are for 0.2 seconds on, 1.8 off. The Cing 3125 (probably same for all other variations like the 8500) is more around .2 seconds on every 4.8 seconds. SO it's probably less usage. Added to the fact that the phone probably uses more than 5mA, all things considered, I'd say it's more than negligible.
However, if you unlock your phone properly, the app "DontForget2" will successful stop the blinking. But, I read that some such apps actually might save the battery life by stopping the blinking, but utilize so much CPU to do so, that you wind up losing battery life in the long run. Unfortunately, I believe this was the case the last time I tried the app.

This would give you less than 4% standby shortage (4h..6h) assuming the 5 mA. Yes, this is negligible.

For me this seems 5 mA is really the best case (gsm off?) and 7.5 mA is with gsm radio on (and bluetooth enabled). Maybe the phone also could spend less then 5 mA if you underclock the OMAP850 CPU?

I bought new HD2.
I have this phone for 4 days.
I think sth is wrong with my battery - 100%, I make a 4 min call, suddenly I have 96%. Another call - 10 min - 89%.
A tried many things, tricks mentioned here on the forum. Didnt help.
(HR, clean system without programs, took out micro sd cards - nothing changed).
Today I ve tried to charge it (from 2%) - I turned off the phone - wait 4 hours. Still amber light. But when I turn on the phone (still connected to a charger) light changed to green (and i saw 100% status battery on taksbar), then i turned off again, and green light changed again to a amber light.
Have you the same?
Or that means I have corrupted battery?
Ive been on many forums, and i see people saying - battery is for 1 or 2 days, and another group - battery for 8-10 hours.
Be grateful for your ansewers - I dont know what to do.
David
It is odd that you are getting an amber light when battery is at 100%. Even if the phone is turned off the amber light should switch to green after a few seconds. The only problems I have are with my cheap $4.00 battery I got from china. It often gets stuck at 75% charging and even when it's at 100% I get an amber charging light (or blinking light sometimes). The standard HTC battery that came with my phone works exactly as it should though. So it does sound like you may have a faulty battery.
As for the various times you see for battery life (2 days, or 8 hours). Much of it is simply users not posting accurate information or not doing proper battery drain tests. I can kill the phone in under 4 hours or make it last 4 days, it really depends on the ammount of use and settings. As for call handling and battery drain, have you tried flashing a different radio yet? Depending on your area some radios can be devastating on battery life. My stock radio was terrible compared to the one I finally settled on.
Hi
I have a pretty serious problem with the battery life on my tg01! I've read the other threads here and at Modaco on the battery problems but thought I'd raise it again. I have a mugen battery now (1100) but am barely getting a couple of hours use. The battery indicator gets stuck and can go from 100% to 40 suddenly, before a few minutes later switching off. I have the original wm 6.1 rom and spb mobile shell 3.5, but the problem was there still when that was uninstalled. I can leave it charging overnight and the battery can suddenly drop and be dead in a few hours.
I'd have thought mugen battery, although only a 1100 one would have made the difference, but there's something definitely wrong because it should not be that bad!!!
What do you suggest is the best thing to do?? Will a different rom definitely solve it? or will it be down to one of the numerous programs I've installed? Or something else? A faulty phone?? It's a problem others definitely have, but is there a single working solution??
cheers!!
as far as i know battery life is a problem with all tg01's, atleast i have the same problem. the huge screen takes alot of power, add 3g or wifi and your phones going to be dead within 2 hours ! one way to overcome this is to make sure you disable data connections when not needed and reduce the backlight settings. i've been able to get over 24 hours using this method but if you want longer life the only real solution im aware of is to get the 2600 mugen battery.
EDIT: I should also mention sense and other memory hungry apps ie opera will effect battery life greatly, infact i find if i use sense my phone can be dead within 8 hours and thats with minimal useage. Constant use of opera will have the phone drained in a matter of an hour and a half.
As for a rom solving it, i dont really think its tied to a rom in anyway but you may want to try noskers rom - i find this one to be the most stable and battery life definately seems longer but i may be imagining that !
Get Task Manager, go to tab "Devices" and stop device "BAT1". Battery indicator will not work, but you can use tg01 till battery fully discharge. After power off (there will be no "shutting down" screen) plug charger immediately.
By this you will use all the capacity of battery, so you can determine if it's battery problem or tg01 battery level measuring circuit.
I've heard about battdrvr.dll modifications for other PPCs to use with higher capacity batteries, but couldn't find anything for tg01.
What Power Saving Settings do you use?

will try that definitely. it happens with the new mugen battery too however.
The Power Saving Settings I use are CPU medium (have tried low and high too), limit CPU speed for battery (tried on and off options) Wifi power consumption, restrict sleep mode OFF, Enable Wifi during sleep mode to OFF, backlight very low. Adjust backlight automatically OFF, 30 seconds backlight timer, 1 minute device sleep timer.
I am guessing there is a rogue program using up the CPU constantly running down the battery. Have you tried a hard reset? (probably a good idea to upgrade the ROM while your at it )
Well I've tried disabling the battery device in task manager. I'm not sure that made a difference, but at least I wasn't able to see the meter jump around..
a hard reset may well sort it, and may end up doing that. I can't see any high intensity CPU programs. anything else? will google latitude suck up the battery this quick?
One other thing which has started recently, which may persuade me to hard reset is that the blue led light flashes long after an sms has arrived. a soft reset stops this, but it will start again when another sms comes through. I've tried one such notification reset program on this forum but its made no difference.
what can be done to stop this?
Edit:
I should really have considered another post really called niggles I need to sort out on my TG01.
But how can I stop the screen going off immediately when a call comes in? I'd rather it waits say 10 secs then go off. the options in pocket toolman do not seem to work. I need the screen on a bit because often I switch to speaker straight away.
When I plug the charger in the TG01 the battery will charge up to 100%. The charging process will then stop (orange light turns off and never goes on again).
If my backlight or wifi is turned on, or anything else is running, the battery will start draining back down, but the charging process will not re-start. The battery will display 100% full as it might somehow detect the charger is plugged-in (?).
When I start using it, although the battery might have drained down to 40%, it will show 100% then suddenly jump to show the actual battery level.
I used to charge it overnight with backlight at full level and it would go from 100% to 0% after using it for a minute or two in the morning. I couldn't turn the device back on, even with charger plugged back in because the battery was so empty.
The trick is to turn off the backlight / wifi when it's done charging, or if you charge overnight, turn it completely off so it doesn't drain the battery when it's done charging.
hope this helps

This is not true. When the battery charges up fully, the orange charging light is extinguished to let you know it has finished charging, however the battery is still supplied with power to keep it fully charged. I know this because I use GPS alot on the phone and when it's fully charged using the car charger, it will still be 100%.
Try hard resetting your phone too. If it doesn't work, then there is something wrong with your phone!
Well it's bizzarre... the battery meter on the tg01 is certainly pretty dodgy.
with the flashing leds, what does anyone suggest? is there a way to change the led notifications back to default?
And regarding the screen going off immediately when a call comes in, it looks like there's no fix - similar threads still have no answer, unless anyone has more suggestions?
Update: I have done a full hard reset and a wm6.5 upgrade but the battery issues are still here. Has everyone who has had this issue taken it back to orange? It barely lasts 5 hours the battery.
Anything else at all to suggest???

I stand corrected.
While this was true before and had tested a few times with two different TG01 both with Orange UK stock ROM, I have retested it now and it does not happen anymore, but I have flashed a new ROM...
Apologies for the confusion.
Hi all
I was reading this thread and preferred to add my 'query' here rather than start a new one.
My TG01 has an original WM 6.5 rom minus the SPB Shell. I haven't experiences any negative experiences yet except for the fact that I have often heard about charging the battery for 8 hours etc and charging it with phone off which I always do except on few occasions I connect with USB cable to my pc /laptop...in my case I will charge my set with the toshiba wall charger that came with the set and orange LED will illuminate a few seconds after charger is plugged-in..from there onwards the orange LED will stay illuminated for maximum 3 to 4 hours and then will turn-off. I am not having any battery problems except for the usual battery drain depending on usage and apps but nothing unusual.
I'd like to know if this is normal? Is anybody else experiencing this? Not charging more than 3 to 4 hours (orange LED turning off after 3 to 4 hours).
I would appreciate some help on this 'doubt'
Thanks
I think it's problem with driver and charging akku. I have custom rom with 6.5.5
and when i charge my akku when it is on 20 % after 20-30 min shows me that 90 % full... After 1 1/2 hour akku full charged.

Well. it's not the solution, but this procedure can be a useful roundabout to access to wifi, or allow you to take a vital picture when you really need it and your battery is under 20% charge.
Imagine that you must send urgently a picture and you can't do it because someone from Toshiba decided this stupid limitation when you are at the end of the battery life.. following the maciek90's procedure, you can save this limitation and drain your battery up to the 0% if you want

guys, also another thing i learnt from my physics class is that putting a recharegable battery in the freezer for 1 hr, somehow give it longer battery! I tried this on my tg01 battery, it strangely worked , or it was all in my mind!
you've gotta make sure the battery isnt wet from condensation when you put itback in the phone! my battery last slightly longer. i dont do it often, only once every now and again... try at your own risk!

I definitely think it is either level measuring circuit problem or battery driver itself - not too big power consumption.
I can repeat without any problems situation where battery level suddenly decreases about 20-30% . I noticed it only during internet operations via GSM so utilizing radio. Why , I do not know . How to fix it ? I do not know yet but it is enough to restart system so that battery indicator start to show correct value - until next failure .
I thought when bad indication occures it would be enough to stop-start baterry driver using way You described. It does not work. Stopping driver cause battery indicator shows unknown level. Starting driver not fix it. Battery indicator still shown unknown value. Only restart fix it. It should not behave this way.
Maybe problem is not in driver but top bar of today screen when battery indicator exists, should have any kind of reset too?
BTH. What software is responsible for displaying battery indicator ?

Today morning next described previously error concerned with GSM radio.
I had GSM radio switched off in the night and phone in sleep mode.
Morning, when I set phone to operational mode , battery indicator showed 50% - the same as yesterday evening.
When I switched GSM radio on, battery indicator suddenly showed 30% and none phone operation could change it. Only system restart caused battery indicator started to show correct value again - 50%

yes! i am not the only one! recently i got a data plan for my tg01. when i use the data connection for 1-2 minutes, the battery drops 10% and it will stay at its false value until i soft reset. i thought that the problem was with the rom that i was using but i guess im wrong. what ROM are you on? it is very annoying and i have to constantly reset my phone. i have done some test, and if i keep using it, on data, the battery could conpletely go dead like when it is out of power, then when i power back in it is back to its true value. any solutions?!
Hey guys the more i use my note daily it seems I'm hating battery life already. I basically have all features turned off and the screen brightness at its lowest. my battery usage is saying about 2 hours and 45 mins of screen on time till completely dead over an 8 hour period. What's the usual you guys are seeing on this. For only actually using the phone for about 3 hours with no games or special notifications or refreshes. Wifi is off I'm under clocked to 1.1. The battery is atrocious. I know its not made for battery life but being it has a larger battery then any cell and a little smaller then the razr Maxx i expect a little more. Makes me think there is a problem.

A couple of things come to mind:
1) Have you checked CPU spy to make sure you're going into deep sleep? (are you aware of the bug with disconnecting the charger while the phone is sleeping?)
2) Are you in an area with LTE and WiFi most of the day? I know it's opposite of what we're used to, but we've learned that the WiFi radio actually uses far less power than the LTE radio. Just something to think about.
Just some thoughts.
When mine goes into deep sleep I loose 1% per hour (wifi off, data on). I agree you need to get CPU Spy to be sure yours is going to sleep. When the charge wakelock problem occurs I'll loose 3% per hour - that adds up to 1/3 of the total battery during a 12 hour day. The work-around so far is to make sure you wake the phone AND unlock it before unplugging it. Most people only seem to have a problem with non-stock chargers and charging from USB ports.
The single biggest battery user is the screen. I highly recommend using Screen Filter and setting up a Widget set to 75% to use indoors and during cloudy days (then another Widget set to 30% for dark rooms - and turn it completely off for full sun). LED screens use less energy the darker they are, which is why this helps. I go into it in detail here: http://forum.xda-developers.com/showthread.php?t=1544757
Then there is the overnight charging problem (not related to the issue in the first paragraph). Once the phone hits 100% it only trickle charges for a little while. You know when the trickle charge has ended because that's when the "unplug me" nag comes up if your phone is on, or the screen comes back on for a few seconds showing a full battery icon if the phone is off. Once this happens it stops charging - so if your battery was almost full the night before you could hit this stage by 12 or 1 am, then it will start to run down again so the next morning it will appear to discharge fairly rapidly. If your phone is heavily discharged the night before you might not hit this point until 3-4 am (or later if you are using a non-stock charger or USB port), so the battery really will be nearly full the next morning and it won't appear to discharge as fast. The only way to get around the problem is to boot in the morning and then leave it plugged in for 15-30 minutes, or if it is already on, unplug and then re-plug it. Either way it will re-start the charging process and top off properly. The stock charging algorithm is just too conservative IMO. It should cycle the trickle charge mode on and off for up to 8 hours to ensure overnight charges really give you a full battery the next day, and not a battery that is only 96% full. Right now it allows the battery to drain back to 95% before automatically starting the charge process over. So ironically the less you use your phone the day before the less battery you'll have the next day if you don't top it off.
I'm going into deep sleep immediately if i leave my phone off the charger over night prolly 6-8 hours I'll only lose maybe 3 percent at most with wifi on. My standby time is awesome its my on screen time that's the problem. I don't have lte available where i live yet. My phone is always at 98 percent max after charging. I did check out a screen filter before but do i seriously need for my 750 dollar phone to look like sh*t to make it through a day? I jumped from a 4s to here where i got at least 20 standby and 6 plus hours screen time before charging with medium auto brightness full notifications enabled. Granted it is a smaller screen but its also smaller battery with what i would think is more draining data features. I thought led screens were supposed to draw a lot less power? My basic reason for the post is wanting to know what everyone else was concluding from average use of screen time before needing a charge. 3 hours of screen time is like two movies and my phone is dead. What's the point of a big screen cell if i always need to charge it after light use every few hours. Its basically a tv at that point which is always plugged in.
Sent from my oversized communication device.
Which is why I recommended Screen Filter. It doesn't make your screen look like crap, applying a light filter (like the 75% I recommended) just dims it down a little. It works along with the stock auto-brightness feature, too. Using this I get 4 hours of screen time with 15-16 hours total run time. Most people report 3-3 1/2 hours of screen time w/o using Screen Filter. You won't get 6 hours - count the number of pixels on your old phone compared to this one.
With no tweaks other than lowering the brightness I'm averaging right at 4hrs of screen time.
Sent from my Samsung Galaxy Note
i get about 4-3 hours of screen time with my overall screen time ranging from 10-16 hours depending on what else im am doing.
i also have profiles set up to keep my cpu in check while in call or screen off. i keep my phone on 100% brightness ALL the time as well. so if i did choose to dim it i could probably squeeze more life out of it.
Ya I'm at 27 percent right now 13 hours on battery about 2 hours of screen time with screen filter at 64 percent the phone brightness all the way dim. I can't see 4 hours if i tried. I dunno what the hell is wrong. What roms are you guys running? Any refreshes on face book tango scramble with friends etc. i lost about 5 percent over night with everything on. I'm using go launcher and handcent sms mostly occasional Facebook checks and fancy weather widget i use system tuner on demand 192-1.5. with screen off on 192-718 max and call settings. I drop like a percent like every 2 mins it seems when the screen is on. Also I'm on unofficial alpha 2
Sent from my oversized communication device.
Simply put, my battery seems to be able to go above 100% displayed charge. Metrics included. There was no variability in the testing: exact same brightness, pretty much the same sequence of actions. The phone was in airplane mode, so no variance from that end. The device is a 2 month old p765.
The two cases I tested: firstly, charge up to 100, unplug the moment I hear the notification, and use. Second case, charge for 30 mins beyond that notification, then use.
100 - 99%; in case I, it took 41 seconds. in case two, it took 7:26 minutes.
99-98% - case I, it took 1:58m, in case two: 2:20 seconds.
Note that I have previous re-calibrated the battery through draining it. I've been having battery issues where even while reading an ebook @ 75-100% brightness on Aldiko causes it to drain at approximately 1% per 3 minutes. There isn't much beyond the stock lg stuff, which i've trimmed somewhat, active on the phone.
So, is this normal? (I hope not.) My first 'smartphone' and I'm seriously underwhelmed by the 2150 battery.
Had the same issue
Hello SoberDogs,
I have been having the same issues as yourself. I stumbled upon another thread in this forum which the op noted that the battery lasted much longer when he tried a different charger.
So to test this, I fully discharged my battery, powercycled, and tried charging to 100% from my USB port instead of using the wall charger, which unfortunately, takes significantly longer. Previously, my battery would be totally drained after 14 hours of typical use, but now my battery lasts a full day (24hrs) with 20% to spare with similar usage. There may be slight discrepancies in the difference as the test was not conducted in a fully controlled environment but there was more than enough of a difference to eyeball.
I also want to mention that the wall voltage where I'm living at is 220V/50Hz. I have no logical explanation for why this the way it is as the wall charger should convert any voltage/current to the correct charging specs. I hope this response helps you in some way.
If this also works for you, please report back so that we can confirm some kind of common issue exists.
Good luck!

Simply put, my battery seems to be able to go above 100% displayed charge. Metrics included. There was no variability in the testing: exact same brightness, pretty much the same sequence of actions. The phone was in airplane mode, so no variance from that end. The device is a 2 month old p765.
The two cases I tested: firstly, charge up to 100, unplug the moment I hear the notification, and use. Second case, charge for 30 mins beyond that notification, then use.
100 - 99%; in case I, it took 41 seconds. in case two, it took 7:26 minutes.
99-98% - case I, it took 1:58m, in case two: 2:20 seconds.
Note that I have previous re-calibrated the battery through draining it. I've been having battery issues where even while reading an ebook @ 75-100% brightness on Aldiko causes it to drain at approximately 1% per 3 minutes. There isn't much beyond the stock lg stuff, which i've trimmed somewhat, active on the phone.
So, is this normal? (I hope not.) My first 'smartphone' and I'm seriously underwhelmed by the 2150 battery.

Hey guys what's this means?!
My battery is falling down automatically with no use!
See
I am wondering about this faulty behavior because i am in 510 firmware with no extra apps installed
I had this issue with. 475 too.
Help me please if this is a hardware issue send it back for second time in this week!
Instead of i charged this phone two time totally when i am bought it.first time faulty drainage happened yesterday when i played some game and battery went to 80% then i went to sleep for half an hour and when i turn the phone on again,noticed to battery is lost to 30%!

I noticed a faulty battery usage indicator on mine.
It happened 2 or 3 times, when I plugged the USB cable to the phone (other end connected to a PC or charger) and the phone LED immediately turned green and the battery indicator jumped from 60% to 100%.
Nothing happens if I re-plug the charging cable, the phone keeps saying it's fully charged. Even powering off doesn't help.
The 100% power won't drain faster but I noticed that when it goes to 30% the phone will shutdown because no more juice is inside the battery and the indicator will go back to less than 10% after re-plugging the power cord.

In your case i think that's better try it with latest firmware.maybe solved.
But for me,the story is different,unfortunately!
another Q has been busy in my mind. Why sony didn't used a better charger for this phone?! Charger has only 1.5 mA output power! For test, i am charging the phone now with s IV charger (2mA)

Higher mA output is not necessarily better.
Taking more time to charge is more gentler on your battery.
Pumping up the mAh to 2 or higher will improve the charging time, but the number of total cycle charges (i.e. life span of your battery) will go down and suffer.
Anyway, 3 hrs from empty to full is normal, right? Anything quicker is a quickcharger.

Ok.no problem dude.3 hours is good time charge for me,but i have another issue that is explained to you.my battery is falling down suddenly!i don't know what is caused for this behavior.see picture in this post!this is a normal drain after a couple of hours.but after one or more hours that is falling down suddenly to 40%! Without any usage.

Good thing you included screenshots from GSAM, so that we have something to go on now.
Remaining (Av.use) 18:51
This tells me that you once had a phone that was efficient, so from the day you realised this drop in performance, scrutinize what settings have changed (inc app installation)
Remaining (last 15 min usage) 5:47
IF u continue using your device in the way you have done in the last 15 mins, you have under 6 hours left of battery power.
In the 15% discharge since fully charged (and since when GSAM started taking this data on your screenshot), 62.9% of power was used by screen.
Some conclusions can be drawn here.
As you mention, you were probably playing some games during the 4hrs and 11min the phone was turned on(from when it was fully charged and then unplugged), very likely during the latter stages than earlier from when the phone was fully charged.
I see your screen is set on DIM, and that it has been active for nearly one hour. Your display was on for 25% of the time since full charge, and that has only used up 15% of battery.
Whether it is games or video playback, screen will be on, and looking at the data there is nothing faulty. In another words, set at dim, 7 hours or so of continuous display on sounds about right..(1 hr already used plus 5:47 expected left)
Now, if your complaint is that if you turned your phone screen off and left it that way for a few hours, came back, then found massive power drain, again, a few conclusions can be taken.
It is a shame there is no screenshot of the app usage form the exact same period. But, If you left the game app open in the background, it is possible that power is drawn still, possibly if your phone is not sleeping properly. In another words, CPU usage for game is there even when not used.
Do you have stamina mode on?
Conclusion... Form GSAM data, there is nothing wrong.
Looking at the first screen capture in OP, as you say, drain happened when phone was not awake, and screen off. I can only conclude that there was an app(s) open at the time which had been still running. If the app(s) is not closed or hibernated properly, it can happen.
If your phone felt hot at that time, it confirms CPU usage.In another words something was left open. If it was cold, even though the phone had been off for a while, then it could be faulty battery calibration.
And next time you see this big drop in charge, take screen shots of GSAM from apps and system. We would know then for sure.

Special thanks for your great comment
Fortunately,that horrible battery drainage don't happened from yesterday to now.
This means there is no faulty behavior after last full charge that i have been!
I don't know that reason but i done some actions after fully charged phone yestarday:
1.instilling Gsam battery pro as you have seen!
2.Charging with another charger(2mA galaxy s4 charger)
3.setting screen brightness to 30%
4.setting off "optimized backlight"
5.battery calibration with "battery calibration" app
This new informations from my battery behavior after 19 hours fully charged at last day from now and i hope that horrible drainage wouldn't happen in future else!
