You're assuming the LEDs represent one third of the charge each.
I lost one LED after the first charge. After the second charge I still had two showing. Then ten minutes into the third charge it died. I wonder if it wasn't properly charged in the first place since it came partially pre-charged and it only took a couple of hours to top it up to "full".
I am charing my Bee to full now and then I will test again over the next few days.
Well I am experiencing the same "issue".
Just after my last post my phone was depleted, i was playing games and doing heavy navigation on it.
So I decided to do a second charge with the pebble.
20 minutes after it started to charge the second led went off, the phone was about 15%. One led was left. About one hour later my phone reached 90% and the pebble shut down, wont turn on again.
This is really dissapointing because I barely got 2 charges from it, not 3 or 4 as other people here stated, which is exactly why I ordered 2 of these chargers.
Anyways,
I plugged it into my computer USB port and it has been charging since then. It has been more than 10 hours. The charging pattern is pretty strange:
2 hours: first led stop blinking
3 hours: second led stops blinking
10 hours: third led is still blinking
I've been thru a lot of portable chargers. from the cheapest ones to the expensives ones, but the pebble is a strange device.
I'll do more test in this week and hopefully to get 3 full charges out of it.
edit: btw I also ordered a Energizer Xpal 8001 charger for my desire. I got it for $50 in a woot.com daily deal. 8000mah capacity and can charge 12v and 19v netbooks as well.
I have 2 energizer chargers and they worked wonderfully in the 18 months I've been using them. Their capacity is REAL, shows actual remaining battery and the supplied cable are high quality ones.
