Battery drains unbelievably fast!

[sabertooth]

Please tell me if anybody else is experiencing the same problem. If it is just me i wont replace my ppc and find solution for it. If everybody else is going through the same problem i will ditch this.

I mean my older ppc which i have had for two years lasts longer than this. I haven't even inserted my GSM card, nor used wifi etc. And whats more it requires such a long time to get the battery fully charged.

I have updated my roms as you can see below:
Rom Date: Jun212008
Rom Version: MP-1.01.04
Bootloader: MP-1.00.03

...but battery still drains like mad.

I have searched here but not found any solution.

BTW how do you turn the screen to off completely. When i manually turn off the display i can still see light coming off of the screen. My other pocket pc's turns dark completely. This is at my desperate attempt to save power.

Currently I'm turning off the keyboard as well as the SmartWheel, yet another attempt to see if power is conserved. So far it is showing signs that it is. Will let you know tomorrow. However the backside of the ppc still gets heated up considerably more when compared to my other devices that i've had.

How to solve this? My ROM is even more recent than the one posted on HP's website! I really love everything about the Ipaq 612c except this battery issue.

TIA

i suggust you either try other rom or contact hp for exchange, there is known issue with battery for some ipaq 61x

I had the same problem with my 614C.

The battery started draining really fast even without use and another symptom was that it would no longer connect to active sync through the cable.

I had no idea what caused it and it was exchanged by HP.

A week after that I connected the phone to my car adapter (12volt to USB) and the same problem came back. Once again it was replaced by HP and the adapter is in the trash.

I belive there was somethinh wrong with the adapter that caused some electric damage to the phone.

hello to you both,

So does this sound normal? Using programs like AE Button and B_Uptime it says that i have around an uptime forecast of 5 hours and 7 minutes.

So far i have used 1 hour and 40 minutes. I have another 3 hours and a half left.

Does five hours of usage sound normal for a brand new battery?

Anybody else can get more uptime out of their system without underclocking it?

[sergiorus]

Maybe you have ActiveSync always running in background?? See in processes repllog.exe file.

[sabertooth]

no replog.exe in processes registering zero percent usage.

How about you, how long does power last with your 600 series ipaq? Does the battery get hot also?

[thebranded]

mines lasts 3 days with normal phone use (probally lite compared to others) music playing for about 2 hours a day and GPS for maybe 30mins a day, after 3 days i'd have at least 30% battary. Screen on setting 3 (which is almost the same as max anyway) not much wifi/bt though, its a 612c as well.

since you've posted other problems as well i'd ge it changed.

[edit] i get some heat only with the gps and after an hours of continuous music. otherwise its rather cool

Using a registry editor on the Pocket PC add a new DWORD value of DisablePowerManagement with a value of 0 to the following keys:

HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms
HKEY_LOCAL_MACHINE\Comm\PPTP1\Parms

After saving the new DWORDs, turn your phone off for 10 seconds, and then press the soft reset button. Once the phone reboots, you should see a noticable improvement in battery life.

This battery saving trick has been used successfully on many WM devices...

Glad to hear that guys...

I will show this to the people at HP at i'm not B**lsh*ting.

The battery looks different to the one that came with my 612c is white allover. This one is not HP made? But lasts longer?

No, it is an aftermarket battery.
Lasts longer then the original HP, I have one about 1 year.

if anything that battary would last shorter than your current battary (assumeing your current battay is not defective) The ebay one is only 1500mAh while the stock HP one is 1590mAh.

But if you only get say half a day on a single battary, two should last you a full day.

I am trying this now... Will let you know how much it saves power.

But something is strange with this Pocket PC. I use a program such as B_uptime to see how much the device has running and how much it has been idle. (See picture)

http://forum.xda-developers.com/attachment.php?attachmentid=187619&stc=1&d=1242959396

When i press the power button to turn it off it doesn't generate ANY idle time. It seems that when i press the power button the some processes are still active. In this example I have only 2 hours of usage time left.

But with my other Pocket PC, which I have the exact applications installed and exact applications running, if i press the power button, idle time is never zero. So for example in a day i would typically have five hours of Processing Time and Five hours of Idle Time. Not so with the Ipaq 612c.

This is definitely what's causing the PPC to be warm even when i'm not using for it for hours.

I use ROM by Yevg001 with FW 0.89.

When I disconnect my active sync. I have set an application to automatically kill active sync. When checking processes, replog.exe is not running.

So what gives??

I have found the bloody culprit!!! :mad:

Do not install SPB Phone application that came with your phone.

UNINSTALL IT IMMEDIATELY!

Now when it's turned off, the processor really sleeps ;)

[thebranded]

strange, i use SPB shell and have not noticed any battary drain. The before mentioned battary life was with SPB shell running. I too use Yevg001's rom (1.4 rev2 to be exact) with FW 0.89.

[sabertooth]

strange indeed :confused:

all is o.k now...

I now just have to check the battery problem where the ppc resets its self (or turns off by itself) when calling or receiving a call when the battery level is below 50%...

If that happens then i'll get in touch with hp tech support...

thanks to all...

No Not SPB Shell but SPB Phone and not the latest version. The version that came with box, the older version.

I would also commend HP Indonesia, they have been extremely helpful, kind and responsive, thanks HP!
