about one week ago I noticed that battery in my N1 was empty in 5-6 hours after charging.
My first though was that 4 years battery is just old. I bought new one (1800 mAh). Unfortunately it didn't fix the problem.
Battery stats didn't show anything interesting. So to check what exactly drain my battery I had to disable one by one GPS, WiFi and finally 3G. I noticed that if phone uses 2G network then power consumption is normal. But regardless of GPS, WiFi, BT etc.. seems that only 3G is guilty.

My question is why after 4 years of using N1 suddenly 3G drains my battery? I have turned it on since the begining.

I already tried:
  • buy new battery
  • remove battery stats
  • full wipe

ROM: 2.3.7 GB by euroskank CM7.2-20131028.2353-N1 FuZZ_

PS. It shouldn't be connected, but at that time I started to use my N1 to deploy application which I develop. It uses localization (GPS/network) and Google Play Services.

It seems that something in 3G module is broken. It can takes 40% battery in 2 hours.
In the same time 2G takes 1%.
Strange... 4 years it worked very well till now
