View Full Version : Excessive battery drain

My Alpine has suddenly decided to drain its battery very quickly, for no obvious reason. It just went from 100% to totally flat overnight, and this is with GPRS, wi-fi and Bluetooth all switched off. Usually I can keep it at home in this state for several days with only a small drop in battery power.

I doubt the battery is at the end of its life - it's only a few months old, and it suddenly developed this problem, having been fine up until now.

Any suggestions anyone please?

Has it only done it the once so far? Mine did it a couple of weeks ago for no reason, charged it back up and it has been fine ever since. Might just be a one off!

Mine has done this twice in the last 2 weeks

Happened since installing the Modded 162 / 1.04 rom from here?

Are others having the porblem using this ROM? if so may be worth a ROM change

I've now done a hard reset and this seems to have solved it. I'll let you know if it happens again. I doubt it's the ROM version, as I have the latest official O2 released ROM.

I've found the culprit!

... well, I have half an explanation anyway. Last week, I updated my ROM from the official O2 site - to Ext ROM 1.11.169. I have now hard reset and reverted back to 1.11.162 (with Radio 1.04), reinstalled my software, and it's all working as normal.

I run Tom Tom Navigator 5 - don't know whether this had anything to do with it, but the power drain characteristics were similar to if I'd left Tom Tom running (except I know it was definitely closed down). I even hard reset and uninstalled Tom Tom and the problem was still there - until I did the ROM downgrade to .162 again.

Anyway - it's fixed - I hope this is useful if someone else gets this problem.

Andy.
