Hi guys. So, i?ve had my Lumia 1520 since May. I installed 8.1 dev preview and everything was fine, battery was great, even when i had 3g turned on the whole time.
Then, in August, i rolled back to 8.0 in order to get Cyan and since then, it seems to me that my battery got worse. I did a hard reset and it didn?t help. I still get through the day, but the battery is acting weird, sometimes it doesn?t drain at all even for 20 minutes, other times it drain a few % even without any use. I always turn my 3g off when i am not using it, wifi also. I have a few apps running in background, but that?s been since i got my phone. My average drain is about 15 - 20% per hour during normal usage.
So what do you guys think? Should i get my battery replaced or is this normal drain and i should expect more? Eventually, i could do another rollback to 8.0 but i doubt it would change anything and i don?t really want to go through that hassle again.
I am currenly running WP 8.1 Update 1.

When you say you rolled back to WP8 did you use Nokia Software Recovery Tool or something else?

Have you moved to WP8.1.1 on DP?

I've heard that Update 1 on DP isn't the greatest for battery life. I am using it myself and I have to admit my battery has been dying pretty rapidly.

That could be the issue here. If you're up for it, why not go back to just Cyan and see if your battery improves. There's many threads on here complaining about battery life and Update 1.

Is it possible the phone hasn't accurately calibrated the battery usage after the reflash? I understand phones have to learn based on actual experience which was erased by the re-flash. In other words, the battery usage may actually be the same but being reported differently.
