I have O2 XdaII i Back up Battery 100% on screen but i remove main battery then i insert main battery into the phone it run customizing.
Someone know help me!!
I have same problem my friend
I have the same issue. I called O2 support and they told me that i need to change the backup battery. It must be the hardest battery to find and once you do find it you have to hope that that is the issue and not something else. Here is the only link it the 'world' i was able to find and I believe this is the battery we're after (copy the whole link in the IE or it will not work):

Let me know how you went with this.
It looks like a button cell / hearing aid battery...
Not sure, if shown battery will fit. I didn't dig Alpine, but Himalaya has Maxell CR2016 rechargeable lithium battery.
XDA IIi backup battery
As far as I know there is no separate 'hearing aid' type back up battery for the XDA IIi - it uses persistant something or other - i.e. it draws power from hte main battery and uses Flash Ram. I have a regular problem reporting backup battery low if I have charged the battery separately from the XDA on the cradle and then inserted it - It seems that the back up only charges when the XDA itself is put on the cradle

As I know its not CR2016 but ML2016
CR type is not a rechargeable one
In need to know the voltage across the diamond standard battery (900mAh) when the battery is fully charged and when the battery is fully discharged (the phone automatically switched off)
Could someone give me this information?
When my battery is low I read 3.2V
When my battery i high I read 4.1V
Is this correct?
That's about right, +-.1
Thanks, I've a lot of problems with the charging and discharging cicles, this information could help me to understand
While which is the charge current when the battery is fully discharged?
For my Diamond it can be very high, up to 800mA (I know it from BatteryStatus), it is a normal value?

Try a program, "PowerGuard", it's a very nice (and free) program developed by Muyz that will give you current and temp info, including graphs with a lot of flexibility in settings. You can get a good feel of where the current draws are. I think charge current is in the area of 700-800mA on initial charge.
Or another called Battlog. It,s better because it logs the measurements - on Powerguard it's difficult to see the actual (current, not in electrical, but in time sense ) measurement.
Thanks I'm going to try them
For now I'm testing Batlog...
This evening I'm going to make a full charging log, so I could post it tomorrow
Could you do the same? This could give me the possibility to compare them
I'm experimenting some problems with the charging circuit

I agree with mjaxa, since your post I've found and installed Battlog. Works great on my Diamond. Very robust program and easy to read the log file or import into excel for analysis.
I have no idea why I didn't find this software when searching for a good battery monitor for my Diamond except I must have not used "log" in my searchs.
Thanx mjaxa.......

I should, of course, also thank Palladium TD now that I've found the source for this fine program.
I'll also add that while the data logging is very good, I found that some of the functions do not work on my Diamond (US ROM 1.93). I know it's a beta program or maybe I just haven't figured it out yet. Using 0.2.3.130 beta I have noted:
No response on the help and other icon on the left side, battery temp read is off by a factor of 10 (noted on the Battlog thread) and cum use (mAh) does not display.
I'll post the comments on the correct thread.
In the following I reported the log of my battery charging cycle in txt and graphic format
If you can post comments or other logs, I'll appreciate
P.s. another bug in Battlog (I'think) is related to the sampling interval, as you can note observing the X axis on my plots: it is not constant in time
No one want help me with a charge/discharge log?
With the holidays I haven't had too much time to work with battlog and the phone use is not typical. I did run about 16 hrs of data and it does give some insight.
Charging overnight looked normal with current draw cycles at 2hr intervals for mail checks.
I was going to upload the excel file, but the format isn't permitted. The txt file is too large. I'll mess with it some more, but I didn't see anything that was unlike your data. 800ma on initial charges, -200ma on using various applications and phone calls, as much as -800ma on internet use and -9 to -20ma on locked standby. I did not see what I'm looking for which is an unexplainable deep discharge, overnight or during the day, I'll keep monitoring.
Does anyone know of software to monitor the charge going into / power being consumed by the Kaiser. I need to know volts or amps rather than just knowing how much charge I have, which all the titles I have found seem to do.
Many thanks
volts or amps left? or the baterry volts/amps supported?
There's a control panel applet called nueCPL-Power, which might be what you want. However, I've never used it myself, and am not sure it even works on the Kaiser.

I think Homescreen Plus will do what you want. Gives you the current in or out in real time ( as + or - mA). Pretty sure its HSPlus but do a search. I have it running on mine but I can't figure out which app it is lol!
From DIAMOND's rom :

PowerGuard v1.2 has everything I need. It monitors battery voltage and current going in or out of the battery, as well as temperature; and it shows data in text values and graphical trend.
It can be found here: http://www.freewarepocketpc.net/ppc-download-powerguard-v1-2.html, or Google it. Make a donation if you can.
Good evening to everybody!
Today I've experienced a really annoying thing!
I received a 1800mAh extended battery for my diamond (now I call it "sandwich"!), and today I've had the good idea of trying it in a small trip! well, when it was time to use GPS, all the satellites were down, or better, iGO says that GPS is connected, but it doesn't find any satellite.
Maybe a Radio problem? tryed to change Radio, but nothing happens
Maybe a ROM problem? tryed to change ROM, but nothing happens
Maybe a BATTERY problem? tryed to change BATTERY......PROBLEM SOLVED!!!
But how could it be possible? maybe low cost batteries could have interferences with GPS receiver?
How can I resolve the problem and use the extended battery(it is really long lasting!)?
Anybody has had the same problem?
Please help!
Many thanks!
It is something with the extended batteries, nothing to do about it as far as I know. Use GPS = Original 900 mAh or 1340 mAh maximum. Don't use GPS = 1800 mAh.
So you are saying that I'm only a really lucky man?
sigh!
PROBLEM SOLVED!!!!

Ok this is silly .I ordered an andida 2000 mah battery and I can't edit sys/class/power_supply/battery/full_bat . I can't even access it in terminal with Su . I tried to Change the value from 1620 to 2000 and even tried editing subfolders to But it will not stick .I tried in es explorer changing permissions editing then changing them back so nobody can write but it still reverts back .
Is this kernal related ? If it is can kozmik make it avaible to change the value via aroma ?there is only these options 1620 stock .1800 .2000.or the extended at 3500 mah .
I fear this is kicking out and charging to full capacity and that's why most batterys suck in these phones .
Anyone have advice ?

I tried accessing the "battery" folder using Root explorer, and it caused Root Explorer to FC. (S-Off, pure velocity rom, bell raider)
I have the 2000mah andida battery also, and would like to ask: Is what you're trying to do necessary? What do you expect to happen if you can successfully edit and save the changes to that file?
Well it is part of the hardware files that controls LEDs and etc . What I believe is that it is sensing a full charge at 1620 mah and kicking off . With a green led indicating so. Just like you can leave you phone on the charger all night and it won't over charge it right . HTC has made it in the folders ad. Safety net . Where I'm sure other phones have N auto detect feature .just a thought

I don't think we know if what the OP is suggesting is even necessary for using the 2000maH battery. It would be nice to know that first. Keeping an eye on this one!

i need a script to be made from this ? its in the android.os .
i did someones suggestion to flash a new battery using the android kitchen and it seems to be better lol .just have to learn a bit of java i guess.and the command isnt in adb .
Hopefully someone will correct me if I am wrong here. But you are right, the /sys/ folder is very kernel related. They are not files that can be modified like normal. I will leave you something to do for homework! Browse the /sys/ folder and find your vibe in a terminal. Now this stuff links to your hardware, you cant open and edit the file. But you can "echo 1 > vibe" replacing vibe with the "file" of your vibe and of course no quotes. Now with your phone vibrating push a 0 to it with ........ echo 0 > vibe. Welcome to an excellent question that delves into linux hardware hacking!!!!! As for the mAH with these newer batteries, I am a lot less clear. Unless the battery has the info encoded to it, it should calculate that value from charge/discharge rate, change in battery voltage & change in time.
edit, should be able to use cat to get info btw ie "cat /sys/class/power_supply/battery/full_bat" will show its full value
Neat.
Running
Code:
cat /sys/class/power_supply/battery/full_bat
produced a value of 1620. I assume that is mAh? I currently have an Andida 2000mAh battery in my phone. Does this mean the phone isn't identifying my battery like a 2000 mAh battery? Or.. does it mean I could be missing out on extra life that this battery could offer?
Again, my normal disclaimer. I am not a pro at these things so my info may be off. The battery life SHOULD be dependant upon the actual capacity of the battery - drain rate. The phone should just monitor the voltage of the battery and shut it off when it reaches a minimum level (Lithium battery tend to not like to take a charge if drained too low). Charging is a different story as it will monitor charging rate, battery V and battery temp (Lithium batteries like to explode when too hot). Back to draining, as the batter drains its voltage drops. Now I have no clue if the OS does some sort of tom foolery and crazy calculation using batter V, capacity & discharge rate to get the percentage, or if it just reports back what percent it is between Vmax and Vmin. If its the former, you should notice its seems to last a long time when its nearly empty. if its the former it should stay slope a little bit the opposite way.
Lastly its a really long winded way to say who cares if it actually lasts longer? If it does not last any longer & reports as 1620 you probably got ripped off.

Yeah, it was a cheap eBay battery anyway. Haha... I wasn't expecting too much from it.
In ES Explorer if you go into settings you can change it to explore root (after granting SU permission) and then mount the system as writable. The system file defaults to read only otherwise.

Unfortunately, this class just represents values. You can't modify anything in it (no field setters, and the values are all declared "final", which means you can't modify them.) This class gets populated from somewhere else, and is only accessed to get values.
Like lamebmx says, I'm not so sure that value actually matters. Whether or not the 1620mAh value is hardcoded somewhere, batteries charge capacities change over time (ie worsen the older they get), and they are still able to fully charge because the charging and charging rate are based on electrical feedback from the battery charging circuit.
The charger will provide a certain number of volts at a certain regulated current, and time and test the response of the battery. Charging slows as the battery reaches it's max charge. It's logarithmic. Once the change in battery voltage growth slows to below a certain threshold, the charger will kick off. I very much doubt that the software controls the charge sensing. It might control the min and max charge current available (ie fast charge or slow charge) but I don't think it can control when the charge stops.
I might be way off here, but I've never seen a battery charger circuit anywhere for anything that has a max charge dictated by anything besides the actual voltage feedback from the physical battery.
