So if it drains the battery twice as fast and Kobo claims that you get 2 months between charges, using it for 30min/day, running Nickel. Then you would have to charge it once a month, if running KOReader. I could live with that. I read a lot and charge my Aura HD about once a week. It is easy to always have it ready to read. Compared with my Tablet that almost always needs to be charged if I plan to make any use of it, and then it can only be used for a few hours before it needs charging.
I also picked up a Samsung 2.0A "Travel Adapter" that came with a 5 foot charging/data USB cord. This makes it easy to charge while reading, if I should let it get lower than I like. KOReader now has a "+" added to the charge percentage displayed, when it is charging, so I can tell that it is charging. Having to charge once a week, perhaps while reading, is no hardship and being able to go two weeks between charges, instead of just one week, would not be worth much to me. (Certainly nor enough to put up with Nickel.) Luck; Ken |

One thing I miss from Nikel is the fonts sharpeness.
Is there a trick or script to increse the contrast on Koreader beyond the "darker" option? So sad, there's is a "darkest" option that suits me but is only for pdfs. |

You can change the values used for "Lighter" "Default" and "Darker" to match your preference. Luck; Ken |

That's the reason why I now power off reader if I won't read book for a longer time (in hours). Some people suggest using suspend script (suspend.sh) from CoolReader that apparently has same battery impact as nickel's script. I didn't tried that though. But, just to place here, this is suspend script from CoolReader (actually, from whole Vlasovsoft package): Code:
#!/bin/sh export PATH=$PATH:/sbin:/usr/sbin echo "suspend.sh: enter" handler() { kill -15 $pid echo 0 > /sys/power/state-extended echo "suspend.sh: killed" exit 1 } trap handler SIGTERM sleep 10 & pid=$! wait $pid # disable wifi if lsmod | grep -q sdio_wifi_pwr ; then wlarm_le -i eth0 down ifconfig eth0 down /sbin/rmmod -r dhd /sbin/rmmod -r sdio_wifi_pwr fi echo 1 > /sys/power/state-extended echo "suspend.sh: delay 2s (dragon)" sleep 2 & pid=$! wait $pid echo "sleeping... zzz-zzz-zzz-zzz :)" sync echo mem > /sys/power/state echo 0 > /sys/power/state-extended echo "suspend.sh: normal exit" Code:
#!/bin/sh export PATH="${PATH}:/sbin:/usr/sbin" # Disable wifi if lsmod | grep -q sdio_wifi_pwr ; then wlarm_le -i eth0 down ifconfig eth0 down rmmod -r dhd rmmod -r sdio_wifi_pwr fi # Go to sleep sync echo 1 > /sys/power/state-extended sleep 2 # Because reasons? echo mem > /sys/power/state |

@WolfBack: Depending on the quality of the font you're using, switching CRe to use native hinting instead of freetype's autohinter might help (i.e., set font.hinting.mode to 1 in koreader/data/cr3.ini).
@Alan_S: I merged some minor tweaks to the suspend script a few weeks ago, hopefully things have improved? |

I usually used it but I read somewhere that it may be the reason for the drain battery. Then I give it a try and... YES

Nickel or Coolreader will give me 3 weeks between charging, Koreader gives me no more than 5 days because of large, inconsistent power drains during sleeping - on both my Glo and H2O (both now on KSM8). Using a Sleepcover makes it worse - I have seen the unit light switching on and off whilst I am carrying it with the cover closed. Coolreader has a setting which seems to honour disabling the Sleepcover. I remain hopeful that someone will post a reliable fix but, in the meantime, I read my Epubs on Coolreader and am liking the personalisation of tap and swipe gestures. |

It's a workaround in that I couldn't figure out why my H2O wasn't suspending properly, but with a wait of about 7 seconds I always got a reliable suspend.* Those extra 3 seconds are basically just a safety measure. Perhaps the proportional image screensaver takes a longer time to compute so that the 10-second timeout is insufficient as a workaround? * I mean a real suspend; that's unrelated to whatever the screen might show. |

Also, this is a bit tricky to found out when battery drains faster. To me it looks like it just drains two times faster when I suspend then when I shut it off, but this may be just coincidence. Quote:

I have cover with magnets, so they may affect battery drain in strange ways. Maybe it would be good to have option to turn off sleep by cover with magnets? Quote:
But, can't tell for sure what really goes on. When I turn it off, I see increase in time between charges. This is valid for older version, not for the latest changes in suspend script. |
