*ORIGINAL TEXT EDITED AND UPDATED*

I have flashed at least half of the custom ROMs released for my G3 CID-unlocked MDA for the last 15 months. It has given me great respect for the efforts of kyphur, faria, molski, anchillus, and others. I have spent too much time, as well, following events here due to the 2 issues that leave my “Wizard” performing less than its best – the radio rom (stuck on 2.19.11 because of missed calls/messages) and battery life.

I do use a few add-on apps, but the main 3 I add to most ROMs that lack them are: batterystatus, todayagenda, and smartskey. I’ve tried placing the blame on battery life on overclocking (via batterystatus, I’ve run mine at all sorts of different speeds with and without cpuscaler, w/wo boost, w/wo extra indicators, etc.). I have updated, removed, reinstalled, backflashed (to ensure a extended rom was present, as many said this would fix the battery life issue) apps and ROMs and nothing has fixed the battery issue. Seemingly ever since WM6, I have been able to get about 24-36 hours out of my phone, about half of what I got before. Last night I went back to Molski’s Wm5 Aku 3.3 Crossbow ROM and over the course of several hours, battery life held firm. Then I added my push e-mail account and synced my mail for the first time (I have a lot of mail) which took like 10-15 minutes, and I dropped 10% of my charge (all levels reported per batterstatus, whatever the bias). Whoa, I thought. Well, I will chalk it up to a squirrelly initial indication of 100% because it sometimes seems to show that when it has just been unplugged from the charger, even if it soon resets to a more accurate value. Anyway, this morning the battery issue seemed to still be a problem. Could it be push e-mail, I thought?

So, I turned off the immediate send/receive, and my battery life improved a great deal. Wait, I thought, could it actually not be push e-mail (which would stink, because I NEED that), but the SD card access when it stores my attachments to SD causing the drain (this was suggested some time ago, but I couldn’t recreate at the time, because the CABs supplied didn’t resolve the issue)? I decided to check. I changed the push settings back to immediate (true push, not SMS triggered) and told the ROM to store attachments in main memory again. And guess what? My battery drain issue appears to be fixed!

I really hope this may be the case. It wouldn’t surprise me to learn that all the power users here are setting the option to store to SD card, or running apps off the SD card.

* MORE UPDATES*

I have been testing this theory for several days, and I can say with absolute certainty that the above fixed my battery issue. Some (WM6 and WM5) ROMs are better than others in this respect, but it is definitely fixed - life improved in all of them. I am currently using Business Edition v2 and it often shows 24mA consumption in BS. I am now seeing consumption under standby conditions of just a hair over 1% per hour, and excellent life even when I am working on it, using the phone, etc. And this is with bluetooth on, push e-mail, etc.

I admit I was surprised at the relatively limited response when I first posted, because this appears to be a gripe for a lot of people. Maybe I overestimated that....if it helps a post here would be nice, if only so others see it and can help themselves.

Thanks again to all the ROM cookers!
