Hi guys,

I have been struggling for quite a while to investigate why my battery drain is about 150mA best case. I have installed Onyx micro version and disabled almost all unnesessary services and applications, and yet could not live a day even in stand by mode without recharging. Battery capacity is 1100mA, so with 150mA drain, it lasted less than 10 hours per day.
I have checked almost all available ROM's on this site, starting with the original HTC one.
No luck ! So, I've concluded it was no ROM issue. Then, I started to play with IPL and SPL. I had both version 3.14.
To make the long story short, I found the best combination of IPL 3.14 and SPL 3.10
Now I have 91-100mA stand by current drain all the time. Sometimes during the night this value droops to 41mA.
I am preety happy with this and also wonder whether anyone has managed to get a better battery life for his Elf ?

Cheers.

The two things you haven't looked at are the radio and the SIM. I'd try with a different sim for 24 hours and search for the best radio rom. My Elfin battery life is terrible but I think it's down to using M2D.

there is a lot of factor that could affect the battery life, from software, to hardware, the most common problem, is battery age, as old your battery are, the less it will hold the charge. on my elfin I have onyx 5.1.1, IPL 3.10 and HSPL 3.10, radio 3.39.90(I'm having better signal with almost no difference in battery drain) I use the backlight on the second darker step, not the default second brighter one. I usually take no more than 10 calls at day, each one of about 1 to 2 minutes, usually don't use(and is always off) the wifi, the bluetooth I use it occasionally while driving about 3 miles from work to home, and to listen to music at work, 1 or 2 hours per day. data connection(EDGE) is always on, but not used very often just to check email once in a while and update weather once of two time a day.
my battery holds for 2 days, most 2 days and a half.

I think your battery may be the problem, maybe is quite old.

dont forget it can be affected by the network coverage too. in fact some of the power regulation in gsm network is managed from the base station.

EDIT: i mean, besides a hundred other things network-controlled that can affect your battery life, the antenna can actually tell your phone how much power it must use when transmitting.
