This morning I tried to put an EP500 battery in my X10 Mini. It fits!! The tings are very tight inside, and I had to cut some of the plastic from the panel, in order to put the PCB outside the metal frame, below the camera module. Despite this, I closed everything with no problems, there are no clearances, and no sign of the intervention when operating with the phone.
I saw that SoftwareFailure used a Samsung element, mine was Sony (from Vivaz), which, as I see from the pictures, is slightly bigger, but it also fits with a little modification of the panel.

e10 not charging after battery replacement

Great... so how is the battery life?Thanx.

hello i succeeded in replacing my battery with a modded bst-38 battery,which works fine only problem is that it does not charge when connected to the charger or usb..PLS HELLLLPPPPPP!!!!!

---------- Post added at 10:38 AM ---------- Previous post was at 10:33 AM ----------

The battery used for test is a BST-38 li-ion and should be 1200mah 2€ so I don't expect to be a great battery but this is only for reference.

tear down instructions

Please read all before starting this will help you choose the most convenient acting way.

Removal of original battery from its placing is a pain in the ass, cause it is very well attached to the aluminium cover whith a very sticky double-face tape ...so proceed with caution, after that I preferred to remove that tape: this permits to connect the battery "the rough way (img 10)" and then place the cover whithout sticking.

This battery was easy to disassemble by removing printed tape and making a small cut on the bottom
...but be aware this may be not so easy with others!!

soldered wires, this is a very complicated step for those who do not know how to use a solder very well, short circuit is round the corner, so first solder positive wire, then cover it with a good thermal tape then proceed with green (again cover it) and finally go for black. (however remember to solder wires in a sequence that avoids overlapping of wires while soldering: if the sequence was black>green>red it would have been easy to melt black wire while soldering green wire... and melt both green and black wire's cover while soldering red)
Note that wires are soldered to run on the opposite direction in comparison wiht the original battery wiring, the reason is to obtain a perfect fit into battery compartment and to obtain a better resistance to wire dragging.

Paper tape has been used to insulate battery's body.
Please note that this picture does not show the final battery placing, you should imagine the batteryrotated by 180° (with wires on the right of the current image and then running on the side of the battery up to the hole which exposes the connector).
So make sure the wires are long enough if you are wishing to use this setup
(otherwise simply solder wires to run the opposite way compared to img 8).

(warning: the whole body is the Negative pole of the battery)

Wires need to be cut perfectly to make sure they don't move,
green wire should be a little bit shorter than red and black shorter than green.
Wire's edges are stained, flattened with plain edge pliers to fit into connector (a hammer and a flat surface will do the job too) and cut to result fully inserted (this avoids unwanted wire scattering while plugging into connector). All this paying much attention to not short circuit wires (I suggest to ready wires one by one insulating with tape each edge, when done proceed by deinsulating and plugging one by one).

warning : positive (red wire) and middle battery contact (green wire) are both positive so prevent any hazard, notice that the whole battery's body is NEGATIVE so handle all wires paying much attention!!

yeah I know i did'nt use the original connector but this is not meant to be a permanent solution
and still have the original battery usable

Before closing the hole with its rubber cover I placed some folded paper on the wires shown in image 10 (just to make sure the cables don't move).

Thanks
to TheCuteCriminal for making public that Bst-38 batteries can be modded to fit
hello pls i need your help, i succeeded in changing the battery of my e10i with the bst-38 battery and it works just fine the only problem is that it does not charge when connected to the usb or charger, what could be wrong ????PLS HELLLLP

Better, of course :) It is between 2 and 3 days, with wifi and bluetooth always on, ultra brightness, 1,5 - 2 hours talk. Occasional use of mail, browser, navigation, SMS, camera, Dropbox, Viber, Skype, etc.. Normal use, i do not play games. I put it in an airplane mode during night. With the same use and the original battery, when it was in good shape, i could never get more than two days.

Hey guys. I've replaced the battery in my x10mini with the help of this tutorial to an original SE BST-38 battery, but i've noticed only after soldering the wires that the BST-38 is rated 3.6V and the x10 battery is 3.7. The phone is now not charging or turning on. I've checked the battery with an LED and it's charged..
Is there any way that I can fully charge it and turn the phone on?

Thanks for any replies.

where i get this battary

regarding the 1200mah 3gpower battery:
now seems to have reached its ful capacity (in 5 cycles)
when I made the substitution the original battery used to last 8-9h with 3g data on and without sync (running miniCM 2.3.1), til now it endured about 800-900 charging cycles

It is well known that minicm (cyanogenmod) has a high battery drain under 3g with data on and
this battery lasts 12h with data on and sync enabled (more power drain), + 20 call minutes.
now I completed the definitive calibration, and will test in normal conditions

I can tell it behaves a little better than original when was new and it seems that dischargnig is more linear

takes about 100 min for charge vs first charge's 60 minutes

It took a while to obtain an almost full battery waking, but now it is all ok :)

more details in the next few days




where i get this 1200mah 3gpower battery...?

thanks

Warning : this mod is hazardous as there is no more space and in case of battery failure it may lead to the destruction of the phone.

@SoftwareFailure,

big thank you for this tutorial :cool:

following your instructions with some smoke and solder i was able to fix our x10 mini for only £4.25 (ep500 of ebay)

phone can now be on over 3 days without a charge while before the battery was shot and only rebooting all the time.

i do have to say it's a very tight fit and it will take some effort to get it all right but the fun is great when it all comes together :laugh:

Could someone please post the type of battery and the url where can be founded?

I have an x10 mini (e10i) and I cannot find a source in internet that is clear the model to suit the battery. Sometimes the title says also for e10i but inside the main content says x10 mini pro and other things that someone cannot be sure about the specific item.

In ebay there is a kinps with 2100 capacity but for the reason mentioned above it is not clear if it's ok also for x10 mini not PRO.

Google: kinps 2100mah e10i

First result.

Thank you!

    A. Disassemble the EP500 battery (same way as Gx3)
    499201DSC00138.jpg


    B. Remove the original mini battery from its metallic frame and cut the 3 wires from their solder
    736136DSC00140.jpg


    C. Preparation of the EP500 battery

    1. Remove the coating on those tracks
    2. Cut the thermal protection and bent it so that it's become flat
    3. Resolder the thermal protection
    4. Tin the prepared tracks and positive pole of the battery
    5. Solder the 3 wires of the battery connector
    6 & 7. Insulate the whole BMS board (both sides) using tape
    8. Cut a window in the tape to let the thermal protection be in contact with the body of the battery
    9. Press the BMS against the battery

    D. Insert the EP500 inside the metallic frame

    E. Finished !

    Good work !!!

    Good tutorial & good Job Gx3.......
    This will be helpful for many people....
    And thanks for mentioning my name.....:)

    ps: now im modding our data-cable. Hope after modding,the USB-OTG feauture will be available on our mini's.

    You're right, more details may help.
    After disassembled the EP500, you'll see that the BMS board is separated from the battery, there is a gap between both, and the thermal protection fill this gap.

    Is this enough ?
