Galaxy Tab getting better battery life than official specs?

---

Yes, according to this guy.

Anyone feel the same way?

its better than i expected, but i doubt its better than sammys tests

Same here it seem way better than I expected but I haven't tested the battery life thoroughly yet but indeed it is very good.

Tomorrow I will be flying back home. I'll be in the air for about 6 hours. I have 2 movies to watch, plus I'll be playing games and will listen to music. I am planning not to charge my tab until I get home. Let's see how it goes. I will update.

Being that my battery use is ~80% display, i should probably consider turning down the brightness. Still, I have been playing with it here and there throught the day (about 7 hours away from the charger now) and the battery level is still 75%

Somebody needs to find a way to mod the autobrightness to have a few options...I like the feature, but it is just a bit too dim for me.

My tab lost 10% battery for one hour medium usage (display on, 30% brightness, reading mainly). Dose it mean I have a battery issue here?

no. it just depends on what your doing. Wifi signal strength, Cell radio strength. the position of the moon and sun, etc.

BTW, battery life does not decrease linearly. so the numbers in that post are ridiculous.
the discharge curve will look something similar to this in most cases

(red line, also note phones cut off the extreme ends of the scale with regards to voltage to promote cell life)


it takes a few days for the battery (more specifically the charging circuitry) to get into a 'groove' when it comes to properly charging the battery and displaying the correct percentage.


if you want to know more about the Batteries in our phones and Tablets look at RCcar and RC plane sites. they use the same batteries as phones do so pretty much everything you learn there will apply here (except our phones don't draw 20+amps! )

Mine can easily last and day and a half, very impressed with the battery

Well, I understand you saying here. But 10% (90% to 80%) per hour for reading ebook only is far away from having a good battery at 4000mah. I will give it a few more days to check.

Well? How did that go?
