Battery jumped from 8 hours to 5 day life!

So I recently upgraded from my trusty HTC Desire to a Razr I XT890. Before I started using the Razr, I had it sitting in standby for about 17 hours and it only used 8% of the battery, this was amazing to see having been getting only maybe 8 hours out of the Desire on a regular working day and I remember overnight I had it plugged out once, just in standyby while I slept and it went through about 30% battery in 6 hours.

Eventually I got my micro sim and the Razr I became my main phone. The desire was now without a sim and was therefore unable to check emails with k9 mail etc. It was fully charged and I then plugged it out and began matching settings on certain apps from phone to phone, I'm not sure how long this took, maybe 30/60 minutes of desire usage. Anyway, got the settings copied over and noticed how well the Desire battery had become since taking the sim out, so decided to leave it in standby and not charge it. It's currently been on battery for 3 days, 12 hours and is only at 37% so may well make the 5 day mark at this rate!

This is a vast vast improvement over the standby rate of before and the only difference really is that I took the sim card out!

As I had copied pretty much all settings, I noticed the Razr I life getting worse than it was in Standby itself. Given there was an obvious improvement over connected and non connected sim, I decided to cut down on the amount my emails got checked and this seems to have improved the life.

I had k9 mail checking 3 email accounts every minute so I reduced 1 account to every 5 minutes, another to every 10 minutes and another to every 15 minutes. This seems to have improved the life on the Razr I, I'm not sure how it would have improved the Desire also?

Has anyone else experienced anything like this? Funny enough, k9 mail isn't mentioned in the battery use list so I'm not even sure if that's the culprit?

Since I changed from using my old desire and taking the sim out, it too had jumped battery life to days. I also had cm7 as the rom and that makes a huge difference in battery use in general.

So I wonder what the drain was? My battery life seemed to drop after I set up a proper SD-EXT partition on the phone and went from Mildwild 4.3 to 4.4, but I don't know what may have caused that drop, but this is a crazy change in life just from not having a sim card in it.

I wonder was it the constant email checking or what?

Had similar results from my old desire.
Would it be the phone stayig i constant contact with the mobile network

Phones of yesterday year would use battery alot quicker if you were out of coverage as the phone was constantly searching for a signal

I'm not sure if this is a new thing with the newer androids, a dialler issue or what, but the phone is automatically adding gaps between numbers when I try and save. I've a lot of numbers and prefer to keep them all the same formatting, which is, for example, +353871234567, if somebody rings me, sometimes it comes up as +353871234567 which is grand, other times it might come up as 0871234567 so all I used to need to do was delete the 0 and add a +, now when I edit the number, spaces are automatically added and it shows up something like 087 123 4567. This used to only happen with landline numbers and then sometimes if you tried to delete say the space between 3 and 4, it would delete the space AND the 3!

I thought it was an issue with Go Contacts/Dialler EX but it's happening on EX Dialler too even though I've clicked off the area code setting, so I'm thinking it might be an android issue? Anyone managed to sort it out?

oops, that was meant to be a new thread!
