Dear friends,
I am using an Exec ppc phone. in the recently time, it become very poor battery. When i turn on wifi, i only can use when battery is full. When it reduced to 75%, the device was soft reset. on the other hand, when i turn oFf wifi, i can use till the battery remain 40% then it is softe reset and can not continue if i don't plug on the battery charging!
Please give me an advice or measurecounter!
thank you so much!
Try this:
Control panel -> system -> power, "advanced" tab.
In the "On Battery Power" section,
make sure the tick box is on for it to turn off after x mins.
I had the same problem until I ticked this box. Closing the lid will power down the screen, but not the device, which is a bit annoying.
You got unlucky with a faulty battery, that's all. You can get a new one from eBay very cheaply these days...

Hello to you all,
My new XDA Exec has developed a fault. It works OK when plugged in to the USB on my laptop or charger but when running on battery will only do so for a short time. In fact a matter of a few minutes.
The battery indicator shows the battery at 100% when charged but the phone turns off variously at 95 - 98%. I tried a soft reset and not change.
I tried discharging the battery using small lamp then recharging in the phone. The battery indicator did show a lower %age 80 ish but not as low as I would have thought. Subsequent charging made no difference and the problem persists. Has anyone seen this before? Any bright suggestions?
Many thanks to you all for you time.
Cheers

You battery is dead therefore you would need to change. You are not unique with this problem. That is common issue for Universal (exec) batteries. For your new battery: dont charge with the USB cable and charge when is completely drained.
Hi Bulldog,
thanks for the reply and the info. Regarding charging the unit from the USB port. Does the unit not begin charging as soon as it's plugged in to a USB port? Is there a way to prevent this that you know of? My phone was normally charged for about half it's life from the charger, half from USB.
From what I understand the LI ion batteries don't have a charge memory due to milisecond pulse charging so pardon me for asking but what does the total discharge do for the battery? Obviously it does something but what? (Not doubting you but I'm curious). Is there a away to ressurect a defective battery such as the one I have currently or is it a lost cause. I know some batteries can improve with either heating or cooling by about 20 - 40°C from normal operating temeprature, have you any experience with this?
Do you know if some makes of batteries are better than others?
Please pardon the inquisition but as I spend a lot of time in remote areas it's often quite handy to be able to bodge rig stuff in order to effect a temporary fix and it seems any bits of knowledge help!
Once again many thanks

Hi, I have the exact same problem...works fine when usb or mains connected but only for a few minutes when on the battery. Usually when I give it some heavy task stuff it will suddenly just blank out the acreen and die.
I'm going to try and do what's suggested on the wiki page about masking off the charge indicator contact with tape - run the thing down and charge up again.
otherwise it's a new battery - not expensive - and plenty about on ebay.

Hi Piran,
Be Frank I am not battery specialist. Therefore I cant give a deep explanation what makes the Universal Battery having so many problems with USB charging. For my understanding it is the slow charge which leads to Battery overheat. Therefore All the post here regarding the Battery problems suggest not keeping the universal charged with USB. Just search for Post for "battery problems" and you will find few "explanations"
In Regards whether you could reverse your battery issue. From my previous experience I would say the max the you can get back is some 10-15%. However in your case the issue seams more severe as you device turns off by 90-100% therefore I think you would need to order new Battery.
following procedure I follow to drain my battery:
1) Turn off You Phone Radio (important)
2) disable the "Turn off Backlight" and put your device brightness to "full"
3) let your device drain the battery by him self( prevent doing anything with your device during this time. I found starting application, touching screen etc. leads that the device request a pick of power which the battery is not able to provide and turns the device off.
4) after certain time your battery will be to weak to keep the device on.
5) push the "power button + backlight button + reset pin" to put your device in to bootloader mode. (your screen will be almost off just some info like SERIAL or Bootloader Version will be visible)
6) again keep the device in this mode to drain as much you can until you cant see anything on the screen.
7) repeat this point6 few times as sometimes the device turns of but after trying again the button combination you can put it back to bootloader.
With above the aim is to drain the battery much as possible. After that you charge your device with power connection for min.12 hours. I guess you will gain few % however repeat the draining and charging procedure for next couple charging cycle to see how much max you will get back.
Good Luck.
I faced the same problem with my battery on Universal.
After a complete drain, the battery wont recharge:
1) Connecting the power cord it starts the boot process, after few seconds the power led ligths in red once, the screen blanks and the boot restarts again and again.
2) Using the usb cord the power led flashes in red without further actions.
I have to throw away the battery, I guess.
Thanks for any comment.

Cesare, One thing you could try before given up on your battery. Try to Use your power connection to charge for while before starting up your device.
How much is a new battery?

When I connect the power cord the start up begins automatically.
There is a way to avoid the starting up?

Cesare, you right when you plug in the device it will boot up. However after while (ca.10-15) when the first initialization complete you could go and switch off the screen(with power button) which takes allot power. Anyhow in your case it is really strange as your device behaves like it has no battery at all. there could be 2 things leading to that.
1) your battery is completely dead ( check with a voltmeter to confirm)
2) or something wrong with your Connection clips (battery and device) you could again check with a voltmeter whether you get any juice on those clips.

Hi Bulldog.
I think that the 1st one is the rigth hypothesis. I'll check with a voltmeter.
The connection clips are ok because the backup battery works perfectly.
To drain that battery I connected an optical usb mouse until the mouse ligth went off. Do you think that this action is the reason of the death?
Many thanks again

Cesare, your battery my not complete dead but it is to weak to lighten up your Universal. Said that leads to bad thing which is: you can only start to charge battery when the universal has come out of bootloader mode.
I had such case ones, after not using my device for very long time the battery was completely drained, And as you described the device keep booting after plugging to the power. However after certain time ( I think some 15-30min trying) suddenly I was able to start up. I am not sure whether that would help to overcome the booting mode with less power but you could try to take out your sim card and memory card and try booting. ( again not sure it will help)
Guys - a quick update from my previous post.
I was suffering a sudden power outage at about 75%-85% battery power - just a blank screen - power gone. Didn't happen when mains connected, only on battery.
Well, first things first, I thought...dodgy ROM for WM 6 - so I tried a few of them - Ivans, Ranju's and Beastys - no change - still this power out.
Read the posts on this forum and thought - gotta be the battery's fried.
Sooo,
I ordered a new Genuine JasJar battery and installed it - (let it charge for 8 hours) - since then...no problems - no crashes, stalls or blank outs.
I'm running Ranju's 7.4 with spb pocket plus - htc home, etc,
As a point of interest my old battery stated 3.9Volts when I put my meter across it BUT - a voltmeter isn't drawing as much as the universal - when 'under load' from power intensive apps - hence you think you've got a battery putting out the requisite power when you haven't.
This was a real niggly problem to sort out with potential culprits all over the place:
Bad battery?
Bad ROM?
PCB crack?
Hardware Fault?
At the end of the day it's good to have spent £32 or so and simply got rid of the problem totally.
I'd say to anyone who's getting outs or blank outs at 80% power or below - your battery stuffed and no amount of mucking about with ROM swaps, Freezers, charging/ discharging is going to stop it blanking out on you.
I'd also like to say how appreciative I am of this forum with a great deal of knowledge available from so many users across a very broad spectrum of skills and experience. Nice one!
Hope this helps,
fanger
Hey guys.
I'm experiencing some problems with my Touch HD. When I get it to start I'm really happy with it and every program runs as it should.
My problem is the battery or something like that. I can have the battery power at 70% one second and the next the phone is telling me to either charge the battery or the device will shut down. I try to start it again but at the start screen it says Battery level to low, your device will shut down.
When I try to charge it the LED under the power button will show a solid amber light, telling me that it's charging, for about 7-9 seconds and after that it will either start flashing between amber and green light or just turn off.
I've tried having it like that over night and try to start the phone in the morning and the same message appear on screen, "Warning! Battery level to low! Your device will shut down!"
Read in some other post about someone who had a similar problem, but not quite the same, and that was resolved by removing the battery, plug in the USB cable for a few seconds, disconnect everything and then put the battery back in and start the phone. This works for me about 30% of the time. When it works the battery shows about 60-80% power.
I've tried a hard reset and I've tried to contact HTC without any success. Any suggestions from you guys, you seem to know almost everything there is to know about these phones.
Thanks.

Have you tried keeping the battery out for a day?
When I got my phone, the first 7 charges I turned the phone off and charged it all the the way up (to get the calibration accurate). Now the battery life is excellent, I can use it for couple of days without charging.
You should try returning the phone, seems it is fine software wise. Can you use the phone with the charger in? If yes, then there is probably something wrong with the battery or the hardware that is interacting with the charging.
I've tried keeping the battery out for about 24 hours but it didn't help. I can't start the phone when I have it plugged to the charger. I'm going to return it today and see if they can just exchange the phone in store or if they need to ship it somewhere to be repaired
Thanks anyway.
Sounds like a defective battery to me...
That's a good idea, better to get a new one.

switch off wifi, install Advanced Config, select all power management enabled
and try again. i also had the situation that my hd took 1550 mA. so the battery was sucked empty within several hours. now everything runs perfect...
Have exactly the same problem
I have exactly the same problem. One moment the phone works and charges fine and the next it shows irratic battery levels and eventually needs to be shut down. Following the shutdown you get the 'Battery level too low' message on startup, right after the Smart Mobility screen. In my case I think the problem mostly started when the phone was either just connected to a PC using the sync cable or when trying to top-up the charge using the wall charger. I also noticed that when the problem appears the plug symbol would appear (indicating it is charging) or sometimes not and then when checking the battery level, the indicators would actually go down sometimes losing 2 or 3 at a time until there is only 1 left and the phone says it needs to shut down. Pluging in the wall charger does not help as the LED indicating the phone is charging only stays on for a few seconds.
Now, I had many trials with removing battery, sim card, memory card or any of those in combination and sometimes these seem to work, but I think the key is the temperature of the phone. Every time I went to the car to drive home, where it was cold, the phone would start charging again, when just before that it would not react to anything all the time I was in the warm office.
I have now contacted HTC and am sending it to their repair centre tomorrow. Hopefully this is recognised as a fault and I will get a replacement. BTW, they arranged for a free courier pickup. Not bad, but the key for me is that the phone is being replaced as I really like the phone.
Update: Got a replacement after 1 week
Got my replacement phone today and hope that this time I have no further problems. I also had to return my previous one with a screen problem (see my post here http://forum.xda-developers.com/showthread.php?t=439410&page=2).
Everything went quite smootly and I liked the offer of a free of charge UPS pickup, so the only complaint I really have is that HTC send me a new phone but no replacement screen protector. Just the original screen sticker (the one with some writing on it) had been stuck on. It was in a bit of state like it had been taken off and put back on several times. I just called them to send me a replacement screen protector, but I don't hold my breath to get one. Probably end up buying it from the website.
Hello people,
All of a sudden today after the battery of my topaz got empty I could not start it any more
I get to the waves screen with the rom information and then freezes...even the power button is not working...only battery removal helps
1.I can do a softreset but it doesn't bring anything
2. I can reach the hard reset menu but I desperately need my data
3. I can log to the bootlogger but I don't know what to do then
Any help wil be appreciated!

If you have drained the battery then the power may be insufficient to restart the phone.
Plug it in without a restart and leave it to charge for as long as possible.
You should do this from a wall socket and use a power supply giving at least 1Ah charge current.
If this doesn't work then the battery condition could be terminal, especially if your charging practice has been to allow the battery to drain as a matter of course. They don't like this at all and after a while the internal circuitry will cut off permenantly.
Then your only recourse is to buy a new battery.
Have you got your battery replaced? Has it solved the problem?
hi
my htc touch hd has been a bit jittery for the past week. occasionally just turning itself off or having various hangups.
I have the Stock ROM on it and have not tried to do anything extra to it.
Problem is now it has gone off completely and won't come back on. Took the battery out for 15 minutes and it started briefly and went off again after the very first smart mobility screen.
any ideas?
hard reset if i can get it started or is it a more serious issue?
don
Sounds like you need a new battery.
Hi there,
i agree with stuntdouble, sounds like a hardware (battery) issue. Is your phone still under warranty? If so, HTC could maybe send you a replacement battery?
To diagnose whether it is a battery issue or not, please try the following if possible:
(1) Charge the battery to 100%.
(2) Disable from running or uninstall any 3rd party applications.
(3) Disable Bluetooth and Wi-Fi,
(4) Enable flight mode
(5) Set backlight to maximum settings.
(6) In the power management settings, uncheck any option that would set the backlight to turn off.
(7) Let phone stay idle for 1 hour and check battery capacity.
(8) If there is a loss of 40% or more, then this means that battery is faulty and needs to be replaced.
Best of luck.
My 2 cents
This should help identify if it's a battery OR hardware OR software issue
* Is your battery completely charging? (i.e the light in your power button should be green when fully charged)
* Can you access the Bootloader? If you can, will it stay there and drain the battery?
* Have you tried a complete Battery Charge Cycle?
Battery Charge Cycle (As I do it)
* Turn the device off
* Attach to charger / USB cable and charge the device until the light in the power button goes GREEN
* Remove SD Card and enter the Bootloader
* Leave the system powered on in the Bootloader running from BATTERY ONLY - the device usually does NOT charge from an external source while in Bootloader - Either way, just to be safe, disconnect all external power sources
I use the cycle every once in a while on ALL my electronic devices to ensure their batteries are being completely charged and completely discharged. It is my PERSONAL OPINION that ALL batteries suffer from a "battery memory". Google it.
(8) If there is a loss of 40% or more, then this means that battery is faulty and needs to be replaced.

- This is a good method of testing, however it seems the OP can't get the device to stay on at all, which is why I suggested using the bootloader. So no offence intended by posting similar steps. (I'm not a fan of cutting another man's grass LOL)
Ive been having the same problem as well.
The phone would randomly freeze or even shut off by itself and the only way to restart it would be to take out the battery and put it back in. Sometimes, it gets stuck on the "Smart Mobility" bootup screen and I have to take out the battery multiple times for it to actually boot up to the home screen.
It's been a bit finicky with the charger too. I would leave it charging for a bit and come back to find the phone either frozen or shut off completely.
I'm not sure if I'd be able to test if it were the battery if my phone gets moody and decides to shut off. How do you enter the bootloader?

(mine was not battery issue). The problem is corrupt file system on internal storage or memory card. After fixing the file system, I dont have this problem anymore.
how did you fix the file system? Would a hard reset fix the problem?
Take out memory card and do HR.
It should bring device to original HTC state... so yes, it should fix it.
In the meantime, you can check memory card on some PC...
I have a Galaxy GT-i9505 S4 and whenever the phone is fully charged, I plug out the micoUSB charger cable from the phone FIRST and then after the power charger adaptor from the power outlet. Thats the way to do it according to the user guide.
But, after doing all that after its charged, the phone's screen stays on and the Screen does not time itself out even though I set the display to time out after 30 seconds.
It does time out after 30 seconds whenever I tap something or do something on the screen, or nornally after doing tasks on the phone, it does do its normal time out after 30 seconds.
But I dont know why it did not time out after a full charge session.
Thanks.
I had a smiliar problem, the screen never shut off when connected to a power source. I think somehow the Android debug settings got transferred from my last phone.
These are not the exact words (I use Swedish) but it should get you where you need to go.
Go to Settings - More - About - click "Build nr" until you get a prompt saying Developer options activated - press Back - Developer options - Uncheck "Stay awake".
Hope that helps.

Stay Awake was already UNCHECKED.
And just to understand here, the screen itself DOES shut off during charging, but the screen remains ON after unplugging it from the charger. And the only time the screen times out, is after when I press or do something on the screen. or after normal operating usage.
I just noticed that after I unplugged it from the charger, then I went to another room to do something and this was way longer than 30 seconds, and came back and the screen was still ON.
But, AFTER normal operating usage, the screen always times out after 30 seconds. So, thats OK. No issues there.
I had the problem with the no longer automatically / manually turn-off display and for me it was rename / delete the bootsamsung.qmp in system / media / the cause, soon to rename them or delete the display turns of not more itself off or even manually by button ...
is reproducible, but why no idea, when an idea who likes because nothing is even now what you would normally get in touch oO
