While gema's issue (which was dealing with raw sysfs read data) is gone with this patch, I suspect your issue might well be related to upower. Did you try with the second patch as well? The Provide energy measurement ? A quick skim through the relevant upower code would indicate that it does try to use the energy_now node when present, which may change the behaviour you see.

[Desktop-packages] [Bug 1093543] Re: Battery status behaves erratically
Actually I don't think the energy patch will change much. Fact is that, since we don't provide current_now nor power_now, upower will do, /* the hardware reporting failed -- try to calculate this */ if (energy_rate 0.01) energy_rate = up_device_supply_calculate_rate (supply, energy); energy_rate will be 0 because of the absence of those two sysfs nodes. I'd suspect any issue being in this software-based rate calculation. Something that would be worth trying out is providing a current_now node, which is something the fuel gauge chip provides. That would allow upower to use a different rate calculation mechanism and possibly avoid the issue altogether. I'll post a quick patch to provide current_now in a bit.

[Desktop-packages] [Bug 1093543] Re: Battery status behaves erratically
Well, here go 3 more patches 1 for upower, 2 for the kernel. The upower one just fixes a logic bug that will allow the design capacity to be read via charge, even though the current energy is read directly as energy. The kernel patches are: 1) Fix a bug in a previous patch - even though the datasheet says that energy_now is in units of 10 mWh, it turns out it isn't - it is in units of mWh. 2) Add charge_full and charge_full_design nodes. With these patches, upower seems to report the right percentage, time to empty, etc. Would appreciate some testing from someone suffering from the problem. Remember to apply all the patches (the upower one, these two kernel ones, and depending on which kernel you are running, also the patches that add the current_now and energy_now fields - although those are committed already).

[Desktop-packages] [Bug 1093543] Re: Battery status behaves erratically
The issue here is a bug in the bq27541 fuel gauge driver. The get_property() function is not thread-safe, but reentry is possible in several different scenarios. The attached patch fixes this issue by protecting get_property() via a mutex. Below is the patch commit message, for clarity: * Currently, get_property() and its callees are not thread-safe, since they share some global state, which they access without serialization or guaranteed atomicity. * get_property() can be called in a reentrant fashion from either several concurrent sysfs accesses, or a sysfs access concurrently with an access from power_supply_core.c, which in turn are triggered from a work queue in the driver itself. * This fixes bogus readings affecting the capacity and the charge_now values - possibly others as well. ** Patch added: 0001-power-bq27541-driver-serialize-get_property.patch https://bugs.launchpad.net/ubuntu-nexus7/+bug/1093543/+attachment/3505724/+files/0001-power-bq27541-driver-serialize-get_property.patch -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to upower in Ubuntu. https://bugs.launchpad.net/bugs/1093543 Title: Battery status behaves erratically Status in Ubuntu on the Nexus 7: Confirmed Status in “upower” package in Ubuntu: Confirmed Bug description: I've recently updated my nexus and I've noticed that the battery system behaves very erratically.
