my battery and internet sharing was fine with dp 8.1 but after denim update it is very low about 4 hours and internet sharing is also not working .pls help me
Did you already try a soft reset?.
If this does not help I would recommend to do a factory reset.
Probably you got a glitch during the OTA update.
You also could use the lumia software recovery tool to flash your phone.
For Internet sharing, I think you need to use the Access Point app. (might have to change your region to Eu temporarily). Search on this forum for more details. Let us know how it goes

You don't (and can't change) region in Access point. Download access point app, and there are instructions in this forum on how to copy APN and create a new APN which might help restore your Internet sharing.
