I am having the same problem with the battery, I noted that after the update the battery drains much faster, same usage it used to stay for 40 hours now it on lasts 21 Hello, can you reboot it again? It may be that a lot of data has not been running after the update Hello, i found out that with NFC...

Not only the stupid red cross but the device after the update refuses to go to Deep sleep and drain the battery much faster. Please provide a solution for the Deep sleep issue
