While using my car charger, it won't stay at 100%, will drain while just texting/internet. It only drains down to 97% or so but It's annoying because my EVO 4G would stay at 100% while on car charger.
Should I try to get another battery or is it supposed do to that with trickle charge/discharge?
That's how it works. If you watched your phone all night long, you'd notice it get to 100%, and then drop down to 99 a few minutes later. One day, if you're lucky, it'll be at 100%. Mine was this morning. It charges to 100, then lets itself discharge to 95% or so, then back up to 100, over and over. It also charges super slowly above 90%, not sure why, but I assume it's to "Fill" the battery up as much as possible. Also, if you do some research on battery charging, you'll find out that the closer a battery is to full, the slower it charges. (IIRC 66% of the remaining battery life per charge period. So 0-66% in the same time it takes to go from 66-88.4, 88.4 to 96, 96-98.6, 98.6-99.5, etc.. But I learned this back in High School, and can't find any thing on the internet to support it in my quick 10 min fact search... Lol)
The OG Evo did the same thing kinda, but didn't display it correctly, and it was the cause of the "Dropping 5% in the first minute of use" problem. The phone would charge to 100%, and then discharge to 95%, and stay there, but the battery icon would say 100% until you unplugged it. Then the system would check the battery, realize it was really at 95%, and change the display number.
The Evo 3D just tells it how it is, in real time.
