Yeah I threw that 1% per 30 minutes as a conservative estimate. I checked after that and it was doing something like what you mentioned.
This is all plugged into the wall with the correct adaptor and everything.
I plugged it in for charging 7 hours ago and with about 4 hours of playing around with the ipad at 100% and about an hour with 30-35% is stands at a total of 80% charged.
This is a little more than depressing. Shouldn't affect me most days, but I fear for that one day..
The other thing I don't like is having to sit with that short cord stretched out while it's charging all this time. I'm going to have to get an extension plug just for the iPad.
Has anyone tested how long it takes to charge up from 0%?
I did, but here's how.
Started charging at 1:45pm. Usage non stop with 100% brightness. Battery level 0%.
Approx 3pm, still using it, battery level 12%.
Approx at 5:30-6:00 still at 100% brightness. Battery Level in the 30s% iirc.
Now I turned the screen to 30% brightness, and in another hour or so the battery level went up to 55 odd percent.
So around 7-7:30 I stopped playing with it. And in that hour it went upto 80. I think it finally reached 100% at 10-10:15.
So with mixed usage it took approximately 8:15hrs. I used it to browse the web, install apps and thats about it.
Been taking pictures and surfing the net for 45 minutes now since I took it off the charger, still at 100%. The reason? Screen brightness at 25%.
The charger will not charge more than a percent per 30-45 minutes if you are using it.
This screen is a black hole when it comes to power consumption.
Disclaimer: What I have just described is the first charge cycle, expect there to be some differences in the future cycles.
