I just rooted and installed a custom ROM on my Evita One X earlier in the week. I had used wizzrah's excellent EZToolkit
to get S-off, install a custom recovery and then a custom ROM. I had originally had a CM11 nightly installed, where I noticed high battery drain when having mobile data enabled. I went back to a CM10.2 stable build and have experienced the same. It's a really fast drain while mobile data is enabled, maybe a percent every few minutes. I have an AT&T LTE SIM installed and am in an HSPA+ area with LTE nearby. I keep noticing that the status bar icon keeps cycling between H, H+, and 3G. I had noticed the same with CM11 nightlies, but it's also happening on CM10.2. Is this normal? Do I need to flash a new radio? Something seems a bit unusual.
Recovery: TWRP 188.8.131.52
ROM: CM 10.2.0-evita
Build number: cm_evita-userdebug 4.3.1 JLS361
