what about ur location ????????????????

Out of interest how much more talktime does the 3300mah battery give u?

I used Spb Benchmark to conduct battery tests with both my standard battery (1490 mAh) and the 3300 mAh Mugen Power version. Using the max backlight standard usage test I got four hours and 54 minutes with the 1490 mAh battery and a whopping 11 hours and 3 minutes with the Mugen Power battery.

1850mAh and higher battery extender

I made my very own battery extender. 1850mAh for now, soon 2000mAh and later, 2500mAh. You can find the information on my website at http://www.powercx.com/xda-ii
So far, I can use this on a lot of devices under 5.5v. This only produces 4.8v, so no regulator is needed. You can use any 4 AA battery, preferably rechargeable battery since they have higher amp.
I was able to get 7.5 hours of continuous usage listening to my MP3 on my network using WiFi to download the music on full brightness. This test includes the extender fully charged and once it's finished, it drained my internal battery. 7.5 hours is only 30% left. Without the internal battery, it last 6 hours on the battery extender alone.

Testing my batteries can you give advice?

Hi,
After feeling that something wasn't right with my HP Ipaq HX4700 running time I have decided to look into whether there is a problem.
I have now tested 2 batteries in my HX4700 and just need someone with some *knowledge* to give me some advice on my findings.
1st battery tested is an aftermarket Panasonic extended 3900mAh (assembled in China with Japan cells) with battery cover.
2nd battery tested is the original HP standard 1800mAh battery.
I set the HX4700 W2003CE (sp29841 with sp30939 update) with backlight approx 70% (my usual setting), all auto-off features disabled (backlight/standby), wifi / bluetooth / irda off, TCPMP player playing mp3 continuously from 100% charge until battery reached 10% left.
For measuring battery drain I used acbPowerMeter.
After completely tests of both batteries here are my findings;
Estimated length of test to reach 0% power remaining equaled 5 hours, mAh total drain 1800mAh;
Average drain was 355mA to 360mA
after 3/4 hours 250mAh used 85% power remaining
after 1 hours 350mAh used 80% power remaining
after 1 1/2 hours 500mAh used 70% power remaining
after 2 hours 700mAh used 60% power remaining
after 2 1/2 hours 900mAh used 50% power remaining
after 3 hours 1100mAh used 40% power remaining
after 3 1/2 hours 1250mAh used 30% power remaining
after 4 hours 1450mAh used 20% power remaining
after 4.5 hours 1600mAh used 10% power remaining
after 5 hours 1800mAh used 0% power remaining (This one is the estimate)
Getting the above test results from both batteries shows something is definately wrong!
I am happy that the HP standard battery is working correctly reaching it's 1800mAh potential.
I am shocked and upset that the Panasonic extended battery is only working like a standard battery.
1800mAh is lower than 50% of the Panasonic's 3900mAh batteries potential capacity.
Based on 355mA to 360mA average drain the 3900mAh battery should last around 10 3/4 hours!!!
Any ideas what I can do with the Panasonic extended battery now, or can only the batteries manufacturer fix it?
I have checked and the battery is still under warranty for another 5 months.
Thankyou,
Dan
Battery has been replaced under warranty.
Battery has been replaced under warranty.
Was quite a process but after two weeks of being stuffed around I got angry with the supplier and I was sent a replacement.
I have not used or tested the replacement battery as I have decided to sell the battery 'as new' condition.
I have also sold my HX4700 now. It was a great device and I may regret selling it in the future.
Fingers crossed I will find another device that is a worthy successor.
In conclusion; Li-Ion batteries 'life span' is measured from the date they are manufactured not the date you purchase them. This means that a supplier with old stock may sell you a battery that is half dead. So take this as a warning of what can happen. I recommend checking a 'manufactured date' if possible to save from disappointment before purchasing. If you do get a battery that is half dead then under the consumer guarantees act you should be able to return the battery within the warranty period. Some suppliers are now stating that if a battery looses 20% or more 'life' in its first year of use they will replace the battery.
Thanks for looking.
Side note; Charging mAh???
I am currently charging my extended battery again.
Just noticed that with my HP 2A wall charger connected to my HP cradle it is only reading approxiamately 1000mA charging current via acbPowerMeter.
Shouldn't that be 2000mA? Is it because I am going through the HP cradle?
edit #1;
Just disconnected the wall charger from the cradle and plugged it directly into the HX4700. It still is only reading approxiamately 1000mA charge current.
edit #2;
Battery is now at 80% charge and charging current has decreased to 600mA. I guess the charge current decreases as the battery fills up.
Just connected a HP 1A wall charger directly into the HX4700 and is reading 600mA charge current as well.
Makes me wonder if paying extra for the 2A max output charger was worth it???
Any explanations, advice?
I will be quite annoyed if I found that the 1A and 2A chargers both took the same amount of time to charge the batteries. Ofcourse I am suppose to be looking at testing running time of batteries at the moment not charging, maybe that could be after..
Edit;
I will see if I can find out if the HX4700 limits the charge rate to 1000mA. If so, then HP is ripping people of with 2A chargers that will never be utilised beyond what the standard HP 1A charger can do.
Do you think the charge rate may have been programmed into batteries onboard chip by the batteries manufacturer as opposed to the HX4700 being the limiting factor??
Thanks,
Dan.

No help sorry, the HP HX4700 has no phone functions.
May help others though.
Thread is now concluded
I have now finished updating/monitoring this thread.
Conclusion can now be seen in post#2 above.
If anyone wants to ask me a question or contact me please send me a PM.
I don't have much time to spend in this forum so response to communication will take a long time.
Hi,Everyone,
Unfortunately, quite a few iPAQ hx4700 owners noticed a huge reduction in how long their device's battery would last.
You see, ROM update 1.10 introduced an error where the hand held would think its battery was empty when it wasn't.

3800mAh Extended battery only showing 1750mAh

With battery monitor widget app it shows that the extended 3800mAh battery is only 1750mAh, the same as the stock battery.
Is this the real mAh of the battery or is there some reason that all batteries just show the same mAh?

Firstly if it is a cheap china 3800 mAh battery its quite possible that it only has 1750 capacity, however i would suggest clearing the data and cache for the battery monitor app and allowing the battery to fully charge then almost fully drain to see what the capacity is.

Tested my phone with an ammeter 0%-100% = 1280 mAh??

Surely this can't be right? The phone is supposed to have a 2600 mAh battery.
Is there any other way I can test the capacity of the battery as I can't rule out a faulty ammeter.
I used a quick charge 2.0 charger and it reached 70% after 45 minutes with a reading of 800 mAh on the ammeter.
I'm bamboozled by this.
