Didn't work. But anyway as I said in first post the problem is fixed. The battery has just a very bad voltage curve as i found out using a voltmeter while discharging.
I just waited. It takes until the battery is unter 4V. Then it switched to 99%. The driver isn't the problem just the OEMSPL and the battery itself. Just switch on bluetooth and phone and keep the device on. After max 1h the battery level bar will change.
thanks @ChrBeck it seems i gut a different prob altogether mine seems to be a faulty h/w ,charges up and shows 100% if i remove it from the charger the battery drops quite quick, and when i reset it comes back with almost nothing left but when i charge the battery externally it can keep the charge for approx 2-2 1/2 days. so my artemis does false charge ups i guess.
