@amorek13: From some other threads it appears that there's a pulse audio equalizer which runs in the CPU (unlike the actual player application), it's there to protect the speakers from damage from certain frequencies. If you try with a headset instead then the equalizer presumably shouldn't run.

Hard to say. And as offline mode doesn't recover the device from the Wi-Fi bug, it is possible.

Of course usage that is both CPU and GPU intensive, will use the battery very fast. You don't get too long battery life with a laptop playing 3D games either.

alias b="lshal|g ng.c"

And then to check battery level I use "uptime;b" to get both current time as well as current mAh remaining. Then keep the terminal on background to see both old values as well as new values. Do note you can scroll the terminal text to see backlog.

.
this might be a noob question but how do u key in that vertical line between the l and g "lshal|grep bat".

Ooooh ... thanks for making me try the Symobl option ... that'll be useful ...

... | is also available in the virtual keyboard that you can enable in the settings, and is accessed when you're in a text box with the physical keyboard closed ...

Re: Fix battery time from under 7 hours to over 9 days!
 
my battery life seems to have gotten worse.

Only 11hrs today.

I only have nokia messaging on and the only widgets are the callender and data usage meter. I did not browse either.

I did dl something from extras over Wifi though. I then did the ifconfig command but after inputing it I dont seem to get a response. If i just do ifconfig wlan0 this is i see:

0 Link encap:Ethernet HWaddr 34:7E:39:42:B5:03
BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:6959 errors:0 dropped:0 overruns:0 frame:0
TX packets:4366 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:9467151 (9.0 MiB) TX bytes:415553 (405.8 KiB)

Does that mean the wifi was still on? Even so why would it drain so fast.

*confused*

It's using SDL. Which is not as power-saving friendly as other solutions I was told (my mClock is using PyGame which uses SDL which seems to disable some CPU power saving states).

Command not working
-sh: lshal|grep bat: not found

nor

alias b="lshal|g ng.c"

This one didn't return anything.

Run as root?
