I downloaded free battery widget on the market. It shows my battery is 65%, but stock battery indicator (blue bar) looks like more than 87~90% or so. Is this only my phone or stock UI battery indicator is wrong?
most battery widgets need to be calibrated. after a few charge cycles they give their best "guess" as to how much time/charge you have left based on your previous patterns. Also the battery indicator isnt that reliable. Battstat is a great battery widget that uses the system battery settings, or if you root you can get the battery percentage instead of the battery icon.
I would guess that it just needs recalibrated, yes. Although it may also just be that the stock can't be that accurate. I have another app replacing it so I can't check, but say the entire thing is four pixels wide. For 100% of course it'd have all four pixels. But it may wait until it's below 75% to only show three pixels. Until then all you know it it's somewhere between 75 and 100%. Same with three bars - it could be anywhere from 74 to 50% battery life. It's just that the app's size limits its accuracy.
I've found that the stock battery indicator is a little flakey. I use Battstatt and Battery Indicator to see the %.
