Release 3.7 Battery Life

[T.Russell]

I was on a build that was a few weeks old.  When I installed the 3.7 release, my estimated battery life went down.  I installed the current build from yesterday and the battery life is the same as the one that is a few weeks old.  Does the 3.7 release actually have a shorter battery life, or is it just an issue with the reporting?  Isn't the release build one of the current builds that is know to be good?

I'm guessing you have a V1 Fuze? I saw the same with mine.....the estimated battery life went down some....I think it was 45-50 minutes, but I don't remember exactly....I sold mine two days later after I got my V2(which has much better battery life).
The estimated battery life of the V1 was actually less than that of my Clip+'s with 3.7...lol.

Revision 28000 improved battery time on the fuze v1 but cuased problems for a small group of users so it was reverted in the release. If these problems didn't affect you, you should have the same long battery time with a current build, just not the release. We have not yet decided wether to revert it in the trunk too since noone seems to be investigating a proper fix. See http://www.rockbox.org/tracker/task/11608 for more details on these issues.

The battery life estimate is based solely on the capacity of the battery and a fixed guess as to what the consumption rate is.

Do you have an iPod Video 60/80GB? The two iPod video builds were merged for this release, but the two devices have different battery capacities, so to get the right estimate you have to select the battery capacity yourself.

I could be imagining it but it feels like the battery life is less for me on iRiver H300 series when using Firmware 3.7

Then post a battery bench with 3.7 and whatever build you think had longer battery life.

Without any tests, I can tell you - 3.6 for definite.

Without tests most people aren't going to believe you.

Without seeing a battery bench for both with identical settings etc., this is all speculation.

Probably, but would people even believe it if proper benchmark tests were carried out?

Lol, some people are very difficult to please.

Although I am fairly sure the life is less, the charging issue has unfortunately taken priority here.

If you could actually back up your claims with the with battery bench logs clearly showing a noticeable decrease in battery life, and you had performed these benches in a the same way for both revisions in question (same album/playlist on repeat, same .cfg settings, don't touch the player until the bench completes, etc.) then...how could anybody question it?

But, until you do..... 

Lol, some people are very difficult to please.

No, some people just want to be able to clearly see that other people have backed up their claims/suspicions with facts.
Right now all you have is a hunch, and forgive people for not trusting your powers of perception but Rockbox does come with the battery bench plugin so that you are able to run battery benchmark tests, so it isn't like you need to do a lot to back up your claims.

Although I am fairly sure the life is less...<snip>

Again, if you're fairly sure...do a battery bench with the revision you believe has the shortened battery life, and one with a revision you believe doesn't have the problem so the results can be compared.

And it's nothing personal.  All of us are subject to the placebo effect so it's simply a matter of wanting to verify that a physical cause underlies a perceived difference.
