Battery Problems

[KrazieF00]

My TJ 35 battery seems to lose its charge way too fast, while using it i will watch the battery drop about 1% per every minute of use. and another thing i've noticed is if i charge it while the unit is powered off, when i turn it back on the battery meter will only show about 80% then if i leave it on for about 2 minutes the battery will slowly creep up to 90%, then i have to soft reset to get the battery meter to show 100%. Please someone tell me if they are experiencing similar problems.

this is a common problem for all clies, i noticed this when borrowing my friends, it goes up and down, there is a post somewhere on this forum of TJ series that details it more, hope it helps

This is more likely just slowness in the battery voltage monitoring code and icon update code, and has nothing to do with the actual amount of charge in the battery.

welp, i just did a test, and my fears are confirmed. My battery seems to be messed up. Looping a kinoma video for an hour dropped my battery reading down to 50%. So either i have no clue where everyone is getting run times of 5+ hours or my battery is whacked.

Kinoma with the backlight on high will run down the battery more than twice as fast as an ebook reader (when not scrolling often) with the backlight on low. Cold temperatures will also reduce the Li-Ion battery run time significantly. I got almost 7 hours of run time out of my TJ35 battery once in a warm room, backlight on minimum, IR turned off.

KrazieFOO,

Did you charge it until the orange light turned green before you used it the first time?

Charged it all the way up the first time,

hotpaw4, i know that a kinoma video will put much more drain on the battery than palm reader, which is why i did the test. The websites I have been reading that have tested the TJ35, have not tested battery life with palm reader, they have either used kinoma or Atomsmash and they say they still get a run time of 5 hours+ while looping kinoma or atomsmash

Charging time on Lithium ion batteries doesn't matter, they don't have a memory. So the amount of time you charged it the first time doesn't matter.

[KrazieF00]

so the general consensus is my battery is whacked? i think i'll go exchange it today afer classes.

It is true that charging time does not matter to the battery itself. But the Clies often don't deal well with the battery if itsn't charged fully before its first use. It uses the first charge to calibrate the OS to what a fully charged battery looks like.
