Does anybody else notice?
Does anybody else notice that for some reason, when you pull your phone from the charger and it's at 100%, that the first 1% to be used up lasts really long; probably longer than any other percent? Like I just checked ms posted two things on twitter, checked my email, sent and received about ten texts, and posted this topic and it's still at 100%. Anybody else notice that or have any reasoning for it

I suspect its the battery meter itself...
As batteries charge and discharge, the voltage fluctuates.
For example, the iphone4 uses a 3.7volt battery...
The meter may be set so that 3.7 = 100%, and 3.3 = 0%
Usually the charging voltage is slightly higher than the voltage of the battery, so when you unplug it its at 3.8v. and that 0.1v takes a while to use up so it looks like it stays at 100% longer. The example of shorter time on 100% could be attributed to the fact it just hit 100% charge and just made is at exactly 3.7 and drops to 3.699999 so 99%
Thats my best guess....
Yeah it's weird, after I posted that, I checked Facebook, replied to another topic, texted a few more time, and watched a short video and it was still at 100%, but I think you're right about the percentages not being completely accurate.

I noticed the same about the 100%...but after that the percentage drops rather quickly until around 75%...than I have to work harder to get the percentage to drop at the same rate. Either way, my battery lasts all day and than some (sometimes 2 days with lighter usage)...I'm happy with it. It blows all the other Android phones (now in my drawer at home) out of the water.

I always leave my IPhone on and I plug it in over night to charge. When I get up in the morning the percentage is usually at 100%. For some reason this past Tuesday morning the percentage was at 98% after the nightly charge. First I figured I must have lost power for a considerable period over night or something but that wasn't the case. All of the clocks were still correct (yes even the ones without battery backup) and I asked around the neighborhood if anyone thought we lost power. The answer was an anonymous no.

Yeah I also noticed that, another thing i saw was the fact that when i am at 20% my phone lasts almost a hole day! If it's morning and i forget to charge my phone and i am at 20% ,it usually lasts me until i come home from work!It's great!Before i got i4 i had the iPhone 3G, i used to charge it in the morning and it would barely last the hole day!Not missing those times!
