I am either seeing things or battery life drain is much slower when development mode is left on. I do not know how or why but it's definitely slower drain. And by quite a lot. Or... I'm just going nuts. Anyone else noticed this strange thing or is it just me? lol
Battery life is pretty bad anyway I think. Never the 9 hours I was led to believe it could be. I get a few hours tops with wifi on. Even without it on and not doing much, it's still around 3-4 hours. I did a full test the other day. I left it in standby with a full charge and picked it up exactly 52 hours later. Battery was at 7% and died in 2 minutes. Backlight is at around 30% constant during every scenario. I never change it.
Dev mode off, wifi off. I left it in standby and checked after 52 hours.
Only 52 hours? Hmm can you test it again with Dev mode on, see how long can it last? Though I know it's a torture not to be able to use the playbook for days :P
