5 hours 52 minutes.

I didn't turn mine on AT ALL before it's first full charge (4 hrs, 40 minutes I believe it took) but I don't use it at full brightness quite simply because:

1) I don't need it that bright most of the time
2) I'm used to color PDA's & the methods for getting more battery life out of them since this is my3rd color PDA

So I'm getting 7 hours (50% power left) at 1/4 brightness which works fine FOR ME. It sounds like what you're getting at full brightness is just about right based on what I've read from various websites. (Brighthand said 4hrs 40 minutes on full brightness for example)

Sony should state specifically on their website what brightness level, sound volume, etc that they use in order to come up with their estimate of 8.5 hours. I always assumed from day one that it wasn't a quote for full brightness as it's common for manufacturers to state the best possible time for their devices. If you want to use it at full brightness you just have to live with shorter battery life. According to another review (Palminfocenter) if you were using a T665 at full brightness (same screen) you'd get 2 hrs & 5 minutes instead of the 4 hours 40 minutes on the SJ33. Anyway I hope people are happy with their SJ33's, after 3 full weeks I have no regrets.

Thanks PaulNB, it's nice to know my SJ33 has decent battery life. I have had mine for about two weeks without any regrets either. I had no idea I'd like it so much more than my Prism and Treo. If I had waited another week before buying it I may have opted for the new TG50 however. But maybe I'm better off with PalmOS4 until all the bugs are worked out of OS5.

In the manual it says you can get 17 days/30min a day (8.5 hours total) of use with BACKLIGHT OFF. Completely off, totally dark. (Who would use it like that?) And it says with backlight on you should get 9 days of 30min a day (4:30 total) with full baklight running simple programs, not games or MP3s. It vaguely says that battery life differs under different conditions (playing graphic-intensive games with full sound) and during MP3s. It says the max for playing MP3s with full backlight is about 4 hours. I'll test that and see.

I got 5:05 with full back light and 7:38 with the back light at half.

I think this is OK.

Ok, with backlight set at ~75% (which to me is the best compromise of awsome display and battery life), I got 5 hours 25 minutes.

I think most people are happy with their SJ33, I definitely am! The main point by the original poster was just to make sure his/her battery was performing as well as it should. Most people seem to be at around 4:40 to 5 hours with the test program.

I'm doing the reset charge thing right now since I wasn't that careful when I first charged. I'll report my test results afterwards. The funny thing is it took me a while to run my battery down to 10%. I had the screen on full bright, was playing MP3 on the internal speaker at full volume, and playing BeJeweled at the same time! Now that's a battery stress test!

I've been using a Visor Deluxe for about 3 years. I have been reading this forum for over a month now and finally ordered an SJ33. It came 2 days ago. What a difference the color screen can make!!

I knew, because of this forum, about the "supposed issue" of using the SJ33 during the initial charge so I did NOT turn it on during this charge. If I compare the battery life of the SJ33 to my Visor I'm initially quite disapointed BUT then I think about all the new features I didn't have before (Color Screen, MP3 Player, Faster Processor etc.) and I stop complaining!!

I just ran the Palm Bench with my backlight on 100%. My battery went 5 hrs, 5 mins, 8 secs.

GREAT forum guys & gals!!!

I've been warned on 2 different cellphones now that turning them on before giving them a full charge can cause shorter battery life. I assume that since they use the same type of battery as an SJ33 that a similiar warning is in order. In 3 different manuals for 3 different color rechargeable devices I've owned they all say "Before using your device for the 1st time you must charge it" & they say how long to charge it. What's the big deal, can't people wait 4-5 hours to make sure it's done right ? True, they don't come right out & say it could hurt the battery but they do tell you to charge it before using it for the 1st time & how long that charge should take.

PaulNB, it must be agonising when waiting for it to charge right

Windboi

seems the record now is 5:52....

I got 4:41 yesterday, 10 minutes more from my first test, I'll try just one more time
TO ALL TESTERS, REMEMBER TO PUT BACKLIGHT AT MAX SO WE GET COMPARABLE CONDITIONS
