I know battery patch is not developed by Pali, it was my just 2 cents about it.

In reply to Pali, i'm already using a not default profile, to undervolt my phone. I'm currently running an ULV profile without no stability issues. I did different test using the phone at 600, 720, 805 and 850 MHz too, with no significative differences in battery drain. Is still higher than with the stock kernel.

I also reflashed my phone, to have a fresh and clean installation for the PK, but the problem are still unsolved.

The thing that, more than other, sound me weird, is the time needed to charge the battery: 2hrs, sometimes less too, when with the default kernel is longer, almost 3 hrs or more. Obviously, i tested a second battery too, with the same results.

In addition, i daily use Cony to monitor process in background, there is not something wrong running in background. It just seems that my battery is recognized with less capacity than usual.

No one of you noticed the same problem?

My battery charging time has never been more than 2 hours (OK, according to battery-eye: Longest charge time 2:13).

If your was needing 3 hours or more, you were either running some demanding program while charging, or you are using a non-standard charger and/or non-standard battery.

You could install battery-eye and visually check what's going on with your N900. Powertop may also help, but it's harder to get any (useful) information from that.

After some months of testing we found two different possible causes of the problem.

- First is the concurrency of the Battery patch installation with the latest version of PK. It seems that many of us experienced heavy battery drain in standby mode (eg, during the night, no wifi, no bt, no widget, no data connection, 2g module locked), solved only after removing battery patch (reflashing the n900 without installing it again is the safest way to leave this first problem behind us)

(reflashing the n900 without installing it again is the safest way to leave this first problem behind us)

- The second one, still unsolved, is (again..) a huge battery drain when using the n900 (eg, wifi browsing, reproducing media, the tipical use of a smartphone). Most of us observed that the effective battery life in now half than what usual without power kernel or with a previous version of this. Wondering why this strange behavours occurs only with PK49, we noticed that in the version 49's changelog is indicated a new version of the bq27x00 module.
We also observed that the recharging time is now limited only at 2 hrs (from empty to full ), when with the previous PK versions (and with the stock one too) is around 3-4 hrs (from empty to full).

One of our users removed PK49 on a n900 suffering this kind of trouble, reinstalling the version 48. He got it, now the phone is back to a normal drain of the battery, excluding an hardware failure.

Btw, i didnt install any new codecs or anything. Only updated the kernel to v49 without the bt-mice patch.
