Your probably right, it was just a thought given that the same ROM versions give different responses to the test, just as the same ROM versions given different battery performance.

It is quite possible that the ROM release of version 1.00.09 is not totally identical to the initial release with the hardware. Even on the HP site it is dated as 9 May 05. I would have thought it would have been dated as of when it was first released. So maybe there has been a driver change sneaked into the offical 1.00.09 release that is different from the original and threrefore only a new driver for the power management, for example, may be required.

it looks as if it's the only reason. Wait for HP to release a new update or send it to them so they could restore it to the factory settings? With regard to how long we had to wait for this update this may take much time. I want my iPaq to work properly now, not tomorrow.....

(After creating a full back-up)

Has anyone let the battery run down until the unit does a hard reset

I ask this as a way to see if the updated ROM is actually reducing the battery any quicker or if just incorrectly reporting that the battery is dropping quicker - ie) it could reduce quickly down to a number (such as 5%) but then stay on that number for a long period

I'm game, I'll let my 4700 cook all day until it resets on it's own. Can't hurt anything, and we might learn something. I'll run another full backup, then let it run.

OK, it finally did a hard reset. Battery was at zero, and the backup battery was also at zero. Now to charge it back up and restore my data. 6 hours, minus the hour or so I had started charging, then started over. Again, that's not very good for an extended battery.

Removing the battery and putting it back is right for the original ROM, not for 1.10 (there is the battery drain issue for sure).

When I first got my 4700 I did some benchmarking with BetaPlayer and pocket hack master. This is with the standard battery.

I found I could play music for about 4 1/2 hours with the 4700 running at full speed, and could extend that to about 8 or 9 hours running at 104MHz. Those times were calculated by fully charging the iPAQ, playing music for about an hour and extrapolating the amount of battery power remaining.

Having installed the ROM update a few days ago and now reading about the battery problem, I re-did the test. 62 minutes used 20% of the battery at 624MHz (ie 5 hours 10 minutes to flatten the battery), which is marginally better than I originally got. At 104MHz I used 16% of the battery in 85 minutes (ie 8 hours 50 minutes from full to flat).

That's not much change and maybe even a slight improvement.

As the battery's behaviour didn't improve I upgraded to ROM 1.10 again.
I charged the extended battery and started my test. It had been running down as quickly as a standart one, but this time, having reached 0% it hadn't turned off but showed 40% and continued working, then, having reached 0% again it didn't turn off either but changed to 20% and kept on working. What's with that?

Dear HP Customer,

Thank you for contacting HP eServices.

This is with reference to your email regarding the 1.10.08 ROM update which has caused swift iPAQ battery discharge.

Please note that the ROM update released for the iPAQ hx4700 series has a bug in it which greatly diminishes the run capacity of the battery. Since there is no current update released to tackle this issue the case needs to be escalated to the AET. Thus, we request you to fill up the escalation template supplied to you in our last reply.

Please e-mail us if you need any clarification and we will be glad to help.

Thank you,

HP eServices

Thank You for you response.
Please be aware that I have been using Ipaqs for many years. I am
an 'in the field' agent and am well aware of all the settings to insure
maximum battery life.
Since becoming aware of this problem,
1. I adjusted all settings to save power.
2. I have Soft reset and Hard reset many times.
3. I have drained my battery and recharged.
4. I have used several different batteries.
5. I have 2 hx 4700 units, one with the old Rom 1.0 and 1
withthe new Rom1.10.8. I have tried all batteries in both units.
The old Rom units gets 7-8 hours of battery life with the
same settings and adjustments as the new Rom unit, which gets 2-3 hours of
life. BOTH units got the same 7-8 hours of battery life BEFORE the Rom
upgrade.

I know that the battery is constantly being drained even
when the unit is switched off.

I tried to BACKROM TO THE ORIGINAL but the problem did
not revert.

This issue is definitely a problem of the Rom upgrade.

Please reference this case ID number <ID:728868-805860121>
As I see others are having this same issue.

This is a very disturbing problem as I have lost my ability to use my device
for the length of time I have had before the ROM upgrade.


Thank You \ Robert Mirenzi

I think that you are talking to me!! Yes, we have received the report about the NEW ROM and extended battery problems. After the evaluation, we found that the NEW ROM would rewrite the data of the ROM in the battery. It will cause the running time as short as std battery. After running out the battery, we checked that it still have rest mAh in the battery but 4700 wouldn't use the rest power anymore!

So it appears that the ROM has caused an error in the reported level of the battery - rather than running it down any quicker.

At least that is some relief - hopefullt HP will fix the battery reporting error soon.

They will have to.
At last I understood why not everyone experinces battery problems - not all of them use extended batteries.
I tested my standart battery with the new ROM and didn't find it to have a shorter running time if to compare to the original ROM.
