Hi all guys 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.
