Hope someone can offer some advice.
I have recently noticed some serious drain in the last couple of weeks. From the battery being at 100% when I went to sleep I woke up 6 hours later and the battery was down to 71%! Android OS was showing as 49% of the battery usage. I did a fresh wipe and install however this hasn't made any difference and the drain is still there.
I also have an issue with the external memory card not working, I have so far used a 32gb and 64 gb card and each time they work for a few minutes and then appear to no longer be formatted and info gets corrupted on the cards, i have reformatted and they work fine in a htc desire hd, but then when i put them back in the note they corrupt again.
And finally, I have tried to install cwm through Odin, Odin shows everything has gone through however when I go into recovery mode stock recovery is still shown. so unable to add a custom rom or change the kernel to try and improve battery life.
My baseband version is N900XXUCMK1
Kernel is 3.4.39-2217357 dpi@DELL134#1
Build Number JSS15J.N900XXUCMK2
I am in the UK on Three network
Apologies if this is in the wrong thread but this is the only thread I can post in currently
