I think upower may have logic that tries to limit the file sizes, but I see the following on my system: ls -l /var/lib/upower/ total 14640 -rw-rw-r--. 1 root root 101008 Sep 9 10:34 history-charge-42T4619-7655.dat -rw-rw-r--. 1 root root 4781903 Sep 15 10:54 history-charge-42T4619-84-7655.dat -rw-rw-r--. 1 root root 100732 Sep 9 10:34 history-rate-42T4619-7655.dat -rw-rw-r--. 1 root root 4754805 Sep 15 10:54 history-rate-42T4619-84-7655.dat -rw-rw-r--. 1 root root 49526 Sep 9 10:34 history-time-empty-42T4619-7655.dat -rw-rw-r--. 1 root root 2969440 Sep 15 10:54 history-time-empty-42T4619-84-7655.dat -rw-rw-r--. 1 root root 58940 Sep 9 10:34 history-time-full-42T4619-7655.dat -rw-rw-r--. 1 root root 2162116 Sep 15 10:54 history-time-full-42T4619-84-7655.dat

Yup, you've found a bug. Working on this now. Thanks.
commit 260e62d872f6433348469500247b4db3ae11dd7b Author: Richard Hughes <richard> Date: Fri Sep 17 16:15:38 2010 +0100 Only save by default 7 days data to stop the log files becoming huge. Fixes rh#634228 Parsing huge log files at startup will demolish startup time. Cull old entries when the file is resaved to keep them sane. Also add the needed self tests to check this in the future.
This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
