After two hours of idle in the pocket and one phonecall the green led is still on and the battery icon shows full. If I keep the screen on for a while the battery icon drops to 50%, but with screen off for while it returns to 100%. Hal-device bme readout and bq27200.sh at this point.

As the green led is still on I connect the charger again and it starts charging and pulsing yellow led. After a while, before battery full level is reached I disconnect the charger and led goes out as normal.

If you dont count the strange led behavior the phone feels like its working normally. I'll keep testing the new bme.

I can confirm this but do not know under what circumstances it happens. Many times it works fine.

Re: BME Replacement

What about N9/N950 target ? could an open BME replacement fit in nemomobile ?

Re: BME Replacement

is this bme installed with the PK? Does it fix the issue of the battery randomly dropping off to 4%?

Re: BME Replacement

I dont think this bme solves any other problems directly than the fact that Nokia BME is closed source blob and Palis BME is not. It may ofcourse be better in many ways, I think the main purpose of this is to replace the closed source version and thus enable better compatibility with current and future applications.

Re: BME Replacement

Ok, I can add one more bug to report. Regardless of the current battery level (100% or 50%) after a while of moderate use like web surfing and for example reading mail, the battery level drops to red and the phone sounds the low battery alarm and notification banner tells me that the battery level is low. This does not affect the usage of the phone in any way and the autoshutdown does not kick in. After the work is done, and I put the phone on idle the battery level rises back to 50% or 100%, where it was before moderate usage.

I got tired of the low battery alarm so yesterday I decided to replace the new bme with the stock one and confirm that the 100%-50% battery level and the low battery alarm was connected to the new bme. I installed the stock BME with this line:

Code:

apt-get install bme-rx-51=0.8.55+0m5

After hitting the reboot button, phone went of, but didn't reboot. I couldnt get the phone to boot or to charge. I swapped a full extra battery inside and the phone then responded to power button and booted up. The battery icon was 100% and the green led was on on when the screen was off (normally even with "full"battery after the boot, my phone show one level lower than the full battery). I then concluded that the batterylevel problem had something to do with the bme-helper files and not the bme itself, so I reverted them also back to stock:

Code:

apt-get install hald-addon-bme=0.0.17+0m5

apt-get install libbmeipc0=0.8.55+0m5

apt-get install dsme-thermalobject-surface=0.0.1+0m5

And everything went back to normal. Have to see in the future to test only the BME replacement, if it works without the other new files.

I think I know at least one situation when this happens. And this observation also relates to the posts with which I opened this thread.

With bme replacement (how was it before???), my n900 is quite sensitive to a partial-contact made whilst (ever so carefully) inserting the wall-charger connector.

With usb mode installed one can readily see this. If you make a "hesitant" contact, usb mode will display to request mode selection. The device will charge but in fact thinks it is connected via usb and not the charger. This likely happens because the hesitant (partial-) contact does not register the expected current and so defaults to the lower.

I get the persistent green light when the charge completes under this scenario. Don't know if it always happens however. So far, the persistent green led has not occurred when the wall charger was seen at the start or when I used usb mode to set the mode as "usb peripheral mode" after a partial-contact connection was made (whereupon the n900 sees the wall-charger).

Re: BME Replacement

I'm wondering, has the situation with the BME-replacement gone forward, as the CSSU-Testing now has new status-area-applet for the battery? I think there is also something going on on the backroung that us mere mortals are not fully aware as a custom version of the older applet is mentioned in Estels post.

Has anyone used the BME-replacement with the new applet and how it works?

I am on thumb/testing and have bme replacement. I love the battery applet as it gives the proper info but of course the calibration must be there.

Looks as such:
