I know battery problems have been discussed already, but I still wonder if anyone experienced the problem as I do and what the solution was.

So, after upgrading, my extended battery seems like to be recognized as Standart one. It runs downs just as quickly as standart. Discharging and charging the battery didn't help. I asked for the help HP Service, but the only thing they could suggest is to downgrade the ROM to the earlier version and check if the issue is resolved or not.

Is there any other way out? Thanks for the help.

P.S. I has been waiting for this f*****g update and I'm really disillusioned. WMP10 still doesn't play video in full screen, and now I'm experiencing problems I had never experienced before.

I thought I was the only one experiencing this situation.

I am currently experimenting. I've run the extended battery down to 5%. I removed it, and put in the original battery. I've charged it fully, then run it back down, then recharged it again. Currently running the battery down again. Then I will charge the battery fully, remove it and put in the extended battery and charge it fully.

Hopefully, this will make the 4700 re-'learn' the extended battery capacity. Alex, let me know if you go back to the original ROM, and if it helped.

Before the update, did you fully charge/discharge the extended battery? Also, the extended battery is a different mA rating than the standard one. A rom update, as far as I know, cannot make any difference to how fast the battery is discharged, seeing as the rom update is essentially software, and the battery has no software integration.

I do understand that software isn't connected with battery's capacity by no means, perhaps, it's nothing but a coincidence. I did the ROM downgrade and, as I expected it to be, that didn't help at all. Even more, the half discharged battery was shown as 100% charged. I fully dischared both batteries, upgraded to the new ROM again, installed regular battery and now it's charging. Haven't decided yet what I am to do next, I just hope it'll work this time.

I will agree with you that the ROM update is just software, but that software controls the hardware of the device. Power management, screen brightness, etc., are all controlled by the ROM and have an affect on battery life. I am using the same settings as before the ROM update.

Before the ROM update my extended battery would easily run for two days of normal use, without recharging. Now I am lucky to make it through my work day. I get about the same time with my expensive extra capacity extended battery that I do with the standard battery that came with the 4700.

Has anyone else noticed similar results since doing the ROM update?

Yes.

I had problems at first, then thought it was just the display reading the amount juice left inaccurately, but over the last couple days I've come to the conclusion that my extended battery lasts about as long as my standard.

This really sucks!

Maybe the person from Mugen that occasionally posts here will have an idea. I am disappointed to get no more life out of my 4500 mAh battery than I do the stock 1800 mAh battery. And the aggravating thing is I could get two days between charging it before the ROM upgrade.

This issue has also being reported on the HP Forums. A Jonathan there and I have been discussing this issue. You can read the thread here.

Stronggeek and Alex, are you using both an SD and CF cards together on your 4700's?

My 4Gb CF and 1 Gb SD are working together. But does this cause the problem? I removed both cards and tested for a while. Nothing changed. I downgraded to the previous version of ROM but the Extended battery had the same life time as a standart one. Before upgrading it worked fine. I am at a loss...

P.S. I use HP 3600 Battery.

OK, that means it is not just the Mugen batteries, so I would rule them out (actually didn't think it was the battery, but this confirms it).

I'll try to keep following the HP forums and see if Jonathan gets any other responses, possibly from an HP tech.

I have spent more than an hour in HP Avtive Chat with Shyla R. I've got no help from HP service as usual. They don't know themselves what it might be.

Here is an extract from our talk:

[ Thu, May 26, 2005 2:16 AM] -- Shyla R
Hello Alexander, thank you for contacting HP and for your interest in our Active Chat online support. My name is Shyla and I see you have a question regarding your iPAQ. I'm going to take a few moments to review your information and will message you back very soon.
[ Thu, May 26, 2005 2:22 AM] -- Shyla R
Alexander, please give me few moments. I will discuss this issue with my senior colleague and get back to you.
.......
[ Thu, May 26, 2005 2:38 AM] -- Shyla R
Alexander, is it possible to test your iPAQ with another battery?
.......
[ Thu, May 26, 2005 2:42 AM] -- Shyla R
Please give me few more moments. I am still researching on this issue.
.......
[ Thu, May 26, 2005 2:54 AM] -- Shyla R
Thanks for staying online. I am still discussing this issue with the department concerned.
[ Thu, May 26, 2005 2:54 AM] -- Shyla R
I appreciate your patience and co-operation.
......
[ Thu, May 26, 2005 3:05 AM] -- Shyla R
Alexander, this case needs to be escalated.
......
[ Thu, May 26, 2005 3:33 AM] -- Shyla R
Once we escalate this issue to higher authority, they will work on this issue and then contact you back.
[ Thu, May 26, 2005 3:33 AM] -- Shyla R
They will proceed with the necessary steps.

Everyone experiencing this issue should contact her or report a problem to HP eService. If they recieve more complains they won't deny the problem's existence as they do right now.

OK, after I eat supper, I will get back here and go to the HP site. Something is using more power, SD and CF cards excluded. I'll post back here later.

I too spoke with Shyla R. As I expected, I was told to revert to the prior ROM and check the battery life again. Since I do have a current backup from just before the update, I can revert back rather easily. I don't agree with them, but what can I do? I have to prove my case one way or the other.

I am going to go back to the original battery only, and will charge and discharge a couple of times in the next few days.

When I first updated, It seemed like I had at least the same battery time, if not better. I had not been using wi-fi much right after the update, but only a quick web page or two all day. I had been keeping wi-fi turned off while not being used, and would typically read for over an hour each day and still go home with the battery reading 100%.

Yesterday, I had wi-fi turned on much longer and I didn't seem to get very good battery time compared to what I had before.

I'm one of those who got caught by the nasty typo on HPs download page and loaded the old ROM. I could have sworn there was the slightest improvement in wi-fi performance, so it makes me wonder if there could be some changes to wi-fi, even in the file that is supposed to be the old ROM.

My guess is that they decided to improve the speed of the wi-fi, possibly due to complaints about the performance, who knows, and they gave up some of the power saving, when they really should have put in an option for the user to select which they would prefer.

I'd be interested to find out if anyone else got battery times better or comparable to the old ROM as long as wi-fi was left off.

From my post on the HP Forums:

Quote:

Using the original battery, and having reverted to the original ROM, my battery life after about 5 hours of normal use is 88% remaining. This is what I was getting before I upgraded to the 1.10 ROM. This would indicate that the problem IS related directly to the newer ROM. Reverting to the original ROM is only a workaround, and one I am not willing to settle for. The new ROM has many bug fixes and improvements that I want on my 4700. I will continue using the original ROM and I will switch over to the extended battery when I get home. I'll discharge it and do a full charge like I did on the original battery. I feel fairly confident that I will see the extended life, like I did before the ROM update. Then I will go back to HP with my findings. If it were only one or two of us, I could agree, yes, maybe there is something wrong with our 4700's. But the number of users reporting decreased battery life after the ROM update seems to be growing. And my own findings point back to the ROM update.
