i have been doing some non-scientific but reproduceable experiments

the battery drain is the fastest if i leave a browser window open and then leave the n810 unattended

if i close the browser it is still very fast drain

if i manually stop browserd then *NO* drain at all



i have been tethered to my wifi at home all day with rss open and email open and occasionally clicking through to a web page but closing browserd after clicking through

since 8:45 am (that was about 7 hours ago) i have not charged the tablet... but left email (imap) on all day and rss to refresh every hour....
batterystatus says 86.8% the battery icon says Estimated battery time left, when idle 9 days and when in use 5 hours.

home applets running- internet search, gpe summary

in my non-scientific opinion it is browserd that is causing the drain
