This is not a battery life thread, in short all I wish to know is whether the Droid X battery (which stupidly only reads in 10% intervals) is reported higher or lower than its actual value?

For example, when it is at 70% reported, is it at 79% (or lower)? Or is it at 61% or higher? Obviously logic says it rounds down so it is always showing battery levels lower than it actually is (which is good because your battery is always higher than what it tells you), but it is also plausible that it ticks down (to 70%) when it actually hits 70%, then stays there until it gets down to 60%.

Not really a support question but its something I've been wondering, I assume it is the former as that makes the most sense from both a mathematical standpoint and a logical standpoint (show less battery than you really have left and you will not run out of battery when the phone goes into its battery reserve state).

I always assumed it to be that once it hit 50% or 60% that it was actually at that level.

Thats what I'm trying to figure out......but from what I have read in the past it rounds down to the nearest 10th. This was why (supposedly) the battery seemed to drop from 100% to 90% after taking it off the charger faster then it dropped from 90% to 80%. But from what you are suspecting, when it says 50% you are at 50% and lower (down until you hit 40%), as opposed to being above 50% until it drops to 40% (in which case it drops to 40% as you just passed below the 50% mark).

I'm saying half way point maybe. Like it'll drop to 60% once it gets below 65%, so at 64% it would start saying 60% and stay there through 55 or 56% somewhere in that area? Sounds good... lol

Such a stupid move for something so simple....they have showed they can read the battery at least in 5% intervals based on the power off at 5%, 1% intervals should be capable with any modern battery.

Maybe they will update it eventually to show in 1% intervals like most phones do so we get a better idea of where our batteries are instead of somewhere +/- 5% or so.

Yeah, I haven't seen anything officially confirmed on the reading of it. I know that if I see it hit, say 40% I will plug mine in and it almost immediately goes to 50% at times.....so I'm thinking it's anywhere from 40%-49% that it will actually read 49%.....which I hate because I like higher numbers obviously

Yeah, mine hit 60% once and within about 10 seconds of plugging it in it went back up to 70%, which is what makes me think that it rounds down to the nearest 10th (69% would read as 60%). It is kind of annoying, but at the same time you can keep the thought in the back of your head that your phone has more charge than it says.

But, as you said, no official confirmation so its hard to tell.

Im pretty sure that when it says 90%, its between 90-99%. It drops too fast to be the othe way around.

I do miss the 1% battery level intervals on my iPhone, it's nice knowing pretty close to what you have instead of this 10% crap. At least the battery seems to last long enough that it isn't an issue. Never got my 3Gs to go 24+ hours off the charger like my DX is at now, and it is still showing 20%! And being new to me, I'm playing with it a LOT!

That sounds "kinda" logical... until you get down to the 15% and 5% marks. Maybe at that point it shifts to "reading high' since it stays at 5% until shutdown (I think).
What a perplexing questions wmpeck.
I miss the HTC Eris 1% marks!
