I have had Exchange setup for 3 days. I'm still seeing Exchange Services take a big chunk of battery. It is always first or a close second to screen in battery use. I have tried tweaking the settings. I tried changing from push email to update every 5 min. I even tried changing it to 10 min. I am synching email, calendar and contacts. I have it set to not auto download attachments. Are there other settings I should be looking at? I also turned off 4g since it's not available in my area yet. Phone is rooted, but I'm using stock ROM, kernel, etc. I ordered extended battery but it looks like it only adds ~15% capacity.
For those who have very low Exchange Services battery usage, can you post details of settings?
