If your n900 is constantly connected to wifi, then check your wifi power saving settings

Re: 400% battery performance improvement?
 

It seems that something was draining Your battery life (some script that stopped working? Cell signal quality was improved, so Your device isn't constantly switching between 2G and 3G?), and now it's gone. It's hard/impossible to tell what it was, without powertop readings from situation, when the problem actually *occurred*.

@freemangordon and @estel,

Check the thread linked in the first post. The poor guy suffered from this problem even with the N900 being *turned off* (whether completely or ACT_DEAD is unclear, I vote for ACT_DEAD).

Powertop outputs are also on that thread...

The problem apparently only happened when the phone was *not* connected to the charger, hence my question about bq module.

I don't know if things have changed with KP50, but the bq27.. module was not supposed to be loaded when bme is also running. At least I haven't loaded it since KP46 days.

Now AFAIK nobody has (yet?) had a real problem when combining bq27 and bme. Perhaps we have a case here?!

Re: 400% battery performance improvement?
 

Note that the issue was occurring with a reflash to stock settings as well. Basically the one thing that was constant since I've had it, regardless of hacking, tweaking & enabled hardware, was the extreme battery drain. Was quite depressing actually.:(

The only thing I've noticed that different now, is the messages in dmesg about bad battery calibration. That was not present before.

Re: 400% battery performance improvement?
 

It would drain if the battery was in it at all. Even if I removed it for awhile and then put it back in, without powering on, it would get warm and drain batteries.

@knoxy420,

I don't know what to think anymore. It might have been some bad contact, making the battery actually drain (letting the current flow) even when nothing was "using" it, hence the warming.

What will you say about this friends ? :confused:

From the graph you can see my battery is not fully charged still it runs for 49 hours with lots of cpu usage.:D :D
and good thing is....:cool:

This is my regular battery back up time. :eek::eek:

Re: 400% battery performance improvement?
 

Hmm.. lemme think. Answer: that you are hijacking a thread? :)

So, your battery lasted ~ 2 days. Mine lasts 4 says with low-normal use, a few hours with very intensive use. Your point being?

Re: 400% battery performance improvement?
 

Check the first 30 hours Graph again...
Is this low-normal use ?:confused:
almost 65 % of that time cpu usage is showing more that means it's not a low-normal use.

Re: 400% battery performance improvement?
 

Hey all, just an update on my mysterious/miraculous n900 improvement.

The previous issues were not battery dependent. i can use either of my batteries and get 12+ hours of usage (vs 3-4 hours battery previously). so something in the phone's hardware "cured" itself. I can also now over clock up to 1000MHz and it stays stable. Previously, if I went over 850MHz it would reboot immediately.

I really wish I knew what happened for this improvement.
