I am happy of the Precision of X9 but I only have one problem: life battery!!!!!
during my trecking setting the GPS interval at 1 minute plus activating the log file after 4.5 Hrs the battery is gone and always I cannot track all my activity :-(((
With 1 minute interval the battery should last 12 hours not 4.5 !!
Also the battery charge indicator continuosly change and so it is difficult to understand which is the real status of the battery.
Would it be possible that the battery I got was not exactly new?
how long woudl it take to recharge the battery ( I left usually for 12 hrs.)
Please kindly inform if you are experiencing the same critical problem

I have the same thing in my X9. After 4-6 hours use in 1 minute interval battery is so dead that X9 turn GPS automatically off. And also battery charge indicator did not show the truth.
One time when I was a few days hiking trip and I try to use GPS as little as possible it suddenly inform low battery and did not show my next waypoint. After 2 hous walking I turn GPS again on and battery indicator shows that battery is almost full. And after that I can use GPS about 3 hour more!
This is not fun when you are in middle of nowhere in the forest and want to know where are you. Yes I keep a map and compass with me, but it will be nice that expencive equipments will work that they should work.

After one week on holidays, I'm be back. I was able to test my X9 during this period.
First at all, the battery life was better in comparaison with my fisrt X9. During a trip, I was able to use it during about 5 hours with 1 sec fix GPS and activity mode.
Another day, I was able to use my X9 during more of 9 hours with 1 min fix GPS, and the battery was not completely empty.
But there is still a problem, that is the battery indicator is really not efficient !!!
The GPS is strange. Sometimes I have a very good satellite signal, and just after, it is very poor, in the same conditions. Another thing, I have generally 5/7 satellites in car, but to the summit of a mountain, I can't receive satellite !!!! and data is erroneous : last week I made a trek during 3 hours, and my Suunto said me that the maximal speed was 40 km/h !!!! ; the total distance is 17 km !!!!. Now I know that I very strong (LoL). I must check with the software if there is a wrong waypoint ...
I confirm you that the GPS is very long at the fisrt acquirement.
I note another very important thing : When I charge my X9 with the electric charger (7.5 volts), the battery indicator fall quickly, but if I charge it with a battery (9 volts), the indicator seems better.
