I purchased the XDA Extended Battery two weeks ago from 02 UK . I'm a bit confuse if it is operating when connecting . For example I'm using UPTime Meter v3.2.1 from http://ae.inc.ru/uptime_t.html and http://ae.inc.ru/uptime_sh_t.html great freeware tool. My internal battery status will 60% after long day in office. When returning home the XDA Extended Battery was fully charge 100% use it's charger pack. I connect the Extended Battery to the XDA illustrated in the manuals but one thing I'm been noticing the Extended battery read 60% or the current percentage life of the internal battery. I assuming that the Extended Battery should disabled the internal battery and all power should run from it . I done various soft rest to make sure the correct charge is displayed even in setting\power it reads the same setting. Any suggestion.
The extended battery does not disable the internal one.
The XDA does not appear to use all the extended then the internal or vice-verse but both together in some way as they both drain together but at different rates.
I wrote some code to get the battery percentage but the SDK does not appear to support the external battery properly. Reading about other PocketPC devices it appears that some (compaq I think) provide an SDK to enable reading of the extended battery on their devices but I have not found one for the XDA.
With this in mide what you might be seeing is that UPTime Meter detects that there is an extended battery there but cannot get the correct information for it.
Thanks for reply but I'm not relying on Uptime only I also check Setting\Power and get the same results. Overall your saying the battery is a extension for the internal battery ,which make since but the reading percentage status should change if the extended battery is connected. i.e. internal 30 % extended 50% equal to 80% battery consumption. Do you agree :!: :?:
30% internal and 50% external would give 40% overall, assuming that both batterys are of equal power.

people with wm6 whose battery is more than 11 months old who get a reset at 20% or anytime other than less than 4 % should change their battery , which should solve part one of the problem (because its a common symptom when batteries get old they loose amperes fast and when they dont generate that amount of current the handset resets even at 20% or 45% etc depending on bad condition of battery) ,
another part2 of problem is battery reverse charging which i observed in cross 4.00.5b ,my battery being healthy and new put on chrger seemed to be charging backwards if i keep my handset on while being on charger but turn backlight off,and this is not a good sign ,which indicated either system files needed to keep log of battery are of a handset which is not htc prophet or wm6 does not support battery hardware of prophet properly , although wm6 might support this processor but what is the use of having a ferrari when there is a hole in the fuel tank and it wont run for even a mile.
part3 battery seems to drain faster means again battery logs are not storing properly
part4 battery not seeming to charge fast again prompts to dll files for battery dont seem to support hardware
it is assumed in wm6 rom that it would be so efficient that battery would charge 2 times fast and would also drain 3 times less here

i wonder where is such a rom which would do this and why is it in chinese
It should come from the caribian sea.......
charging two times faster and 3times less battery drain.
This is wodoo..........
Just a miracle.....
3 day standby is easy with PDAViet 4.0.0.6... at least mine
I have battery status with the dynamic 123, 175, 208, so that helps my battery also.

actualy that does not help your battery because when using cpu scaling the batter will keep draining when you don't use your phone because the cpu keeps working to keep the clock down at 123Mhz..
I am using Hastarins 7.6 kernel with ext batt support and Froyostones 3.2 build (Most recent as of Oct 23)
I have done some extensive research, although, i have not yet figured out a way to get an accurate reading, in android, of my extended battery (life percentage)
I have calibrated my battery (charged to 100% w/ phone on, shut off phone and charged until green light, then booted android, then turned off and charged again until green, then turned on and booted android) only to find out that the battery discharges at the same rate as with the original battery all the way down to 0%.... but does not recognize that the battery holds twice as much power. so really, the 100% battery drains to 0% on extended battery but does not recognize that the battery still holds 50% of its power left
i have never deleted my "batterystats.bin" Because i can't find the file anywhere using a root explorer and even recovery, although, i was told that this step is not necessary in calibration.
I have current widget and my draw is around 60mA on standby with BOTH original and extended batteries but It seems the android OS cannot get accurate readings on the extended battery? It cannot multiply the battery meter by 2 so that the drainage is reciprocal to the larger battery, thus resulting in a slower drain (like 10%/hour drain with original battery would equal 5%/hour drain on extended) ?
correct me if i'm wrong somebody please, or am i missing a step (besides deleting the batterstats.bin which i cannot find out how to do even after downloading recovery)
anyone have any information on this ratio?? battery percentage reading and the extended battery? will they ever be compatible for correct readings??
i've got the same problem with a cameron sino 2400 mah battery, but not only on android! i also got the problem on windows mobile (on every radio and rom version).
after removing the battery out of the device, it will show the right percentage of the remaining batterypower, but the batteryindicator is still falling in the speed of the normal battery.
i couldn't find any solution yet, but maybe it's a battery internal problem of the chip inside the battery.
it looks like the device is reloading the battery-chip-data only when plugging in the battery.
can you tell me, if your battery also is a cameron sino battery? or is it an original?
have you recallibrate your battery? Let it drain till 0%, and keep try to turn device on until totally no vibrate, then charge to 100% after 100% turn phone off and charge till green light, unplug and charge with phone off for a few times.
i already calibrated mine many times, but no change in the result.
i have read from anywhere else in the internet, that most people got that problem with chinese extended batterys.
one of that guys ordered a 2300mah extended battery from the manufacturer leicke - looks like it is maybe the same as the original one and he said, the new battery dont have the problem anymore and is working correct.
i ordered the same battery yesterday (for 21,- euro) and i will test it myself. i think the problem is the chip inside the chinese batterys, that will tell the device its a small one.
by the way, my cameron sino 2400mah battery is made of two small batterys that are linked.
i disassembled it!
Thats guy is me ^^ . But I i really dont see the big different between extended and the original . Must i really do the "recalibrate thing " ?

update: now i've got the leicke 2300mah battery with backcover and metal kickstand.
cover is fitting 100% and all looks and feels like its made of high quality.
the batterydraining ist detected correct and i dont have to remove the battery to see the current chargelevel.
the problem was that chinese crappy battery!
only one thing for androidusers: because of the most kernels don't support the extended batterys (temperature is reportet wrong and android is shutting down after booting), you need to change to a kernel like hastarin 7.7 or 7.8 that is supporting the extended batterys.
overclocking of the hastarin linux kernel work with overclock-apps, so there is no need for an overclocked kernel.
i'm very happy with that battery and it cost only 21 euro over amazon in germany.
i will never get a cheap chinese battery again
So, is it correct that batteries have some kind of chip in them?
yes, they do contain microcontroller
cheap chinese ripoffs often are just badly designed, made from low-cost cells and are very dangerous to use
So don't be surprised if your 'OEM' seico, chinapower, mugen, or whatever name doesn't hold promised charge or even work as original battery
Hi,
Last night I purchased my S2 and am in the process of priming my battery. Could anyone tell me what is the standard (in the box) battery capacity that is achieved after the going through a few cycles of charge/discharge I should expect?
Coming from a HTC Desire HD, I am so far impressed with the S2, way better in every respect.
Thanks for your input
Didn't know the battery capacity could be variable in a battery... are you talking about battery duration?
Talking about the value reported in apps, the like of Quick System Info PRO, where one can see the state of the battery. For example, when my DHD arrived, batter was only at 3500mV. After a week of "training", a.k.a. priming of the battery, I reached full capacity of 4204mV when charged at 100%.
I am simply trying to establish where my battery is at today + how many cycles of charge and discharge it needs to span full capacity. Talking about this for example
Breaking In New Batteries - New batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge your new battery two to four times to allow it to reach its maximum rated capacity.

I recently purchased the original LG battery charging pack with an included battery.
So i charge the batteries exclusively using the external charger. When the battery level of the phone goes to around 20-30% I swap in the charged battery. Now the problem is, even though the new battery is charged, the percentage is the same as before i switched out the batteries.
So let's say i swap at 33%, the new battery also reads 33% after the boot.
Is there a way to recalibrate the battery meter?
Found the solution:
The battery swap was done too fast, so the phone didn't realize there could be a new battery inside.
I tried again taking out the battery, waiting maybe 20 sec, then rebooted. Now the battery percentage is accurate again!
How do you override the default android manufacturer info on battery capacity?
E.g
I'm using Xperia C5503, rooted of course. Original battery comes with 2300mAh. I've got a new fatty 3rd party 3400mAh but the Android gauge simply can't get the correct reading of the new battery capacity. I tried setting the new capacity inside of 3C battery monitor pro but seems it's only for internal comparison, calibration also doesn't help probably because it's only meant to calibrate original 2300mAh not anything more or less.
So the result is reading stuck at 1% lasting for 10 or more hours, it's really frustrating. Any ideas?
Well, to reply to myself - I found it.
The solution to 'fix the gauge' with extended battery is to not let it drain to 0% but instead to drain only to the low battery indicator! I used 10% remaining indicator mark (didn't tried with 15% as suggested @batteryuniversity or 5% when battery saving mode switches on), then the crucial point is to switch the phone off and let it recharge in powered off mode till 100%. Repeat the procedure 2-3 times and it should be good.
The charging circuitry needs to learn what the max and min are, so it can then stretch its range to fit the battery's new and much larger capacity.
As a result now I have 3400mAh that holds around 3d6h with more than 8h of screen time. Hope that helps to someone too.
