thanks, i will give it a try. but i am quite sceptical, since i have the battery drain both in android and windows with clean installs

[demorez]

There is definitely something wrong with my device. Yesterday I have installed RemixOS on the tablet, as in the other thread they claim it has good battery life. Playing around with it yesterday unsuspended the device with 88% remaining. In the morning after 7 hours I am having only 50% left !!! It seems the tablet is never entering sleep mode in any OS (I can see emails being synced while it should be suspended). Sounds like a BIOS issue to me, butni have no idea hownto solve it. I am putting some hopes into bios v3.04, but it seems its impossible to get it

i am stuck at the boot screen for more than 30 mins. tried booting to recovery, but it just shows an android logo with an exlamation mark. wanted to install TWRP recovery from the first page, but cannot download it from 4pda

[demorez]

what is bootloader mode?

[demorez]

i am confused now. can someone put a quick quide how to install this while keeping windows intact?

[demorez]

just to confirm this is what I should do:

1. run intel phone flash tool
2. select flash.json from the ROM folder and select “Update”
3. put tablet in DNX mode
4. flash

is that correct?

[demorez]

battery still draining like hell. 40% down in two days without touching the tablet

[demorez]

the timing doesn’t matter, it will stay in DNX mode for a looong time.

it seems location service is not working in 3.0 (was also mentioned on xda)

[demorez]

marcus, you need to boot into android first, then restart and boot into dnx mode. from windoes dnx mode is not working

[demorez]

Settings > Battery does not show anything, only the battery graph. The usage per application is not available. HOwever I have installed the app Battery Monitor Widget, which is showing that Android System is responsible for draining 50% of battery.

Anyhow, when my phone with 2300 mA battery is draining less than 1% overnight with wifi enabled (so approx. 20 mA), than its not possible that a tablet with 8000 mA battery could drain 20% (1600 mA). That means if my phone would have a so high drain it would empty its battery in 12 hours without even turning the display on. Also not to forget that the phone has to maintain cellular connectivity, while the tablet don’t.

yesterday evening i charged the tablet, disconnected it and left it on the table. in the morning (after 12 hours) the battery was only 74%. that was on windows. do you think i have any chance for a refund? respectively you have any idea how to solve this? i have the suspicion that the tablet did not sleep at all, just the screen was off, but i dont know how i could check this

[demorez]

i use firefox and its as slow as chrome on your video. i am quite disappointed with the windows performance of the tablet.
