Quick look: Seidio 1750mAh slim battery for HTC EVO
If you've already checked out my HTC EVO battery tips but still want more runtime without bulking up your phone, Seidio's 1750mAh slim battery is now shipping for $41 from Amazon (Seidio sells it for $50). Although its real capacity has been contested by BatteryBoss, its stated capacity is more than the EVO's standard 1500mAh battery. It's also the same physical size as the standard battery, which means the EVO's appearance isn't altered the way it would be with a larger extended battery that requires its own backplate.
Lithium ion batteries don't need to be conditioned, primed, or cycled the way old nickel batteries do, but Seidio still instructs users to charge the 1750mAh battery for 8 hours before first use and says performance will increase after 5 or 6 full charges.
I don't believe this but will do it anyway so my results from this battery aren't criticized because I didn't "follow the instructions." I just got the unit today so it'll take some time before I can report back with full results. In the meantime, here's a quick look at the Seidio 1750mAh slim battery.
I'm actually already getting good battery life from the standard battery, and I've only applied a few of my battery tips. This is my battery usage from a few days ago:
Usage on this day included 2 hours of 3G mobile hotspot use, email, web browsing, Android Market, and a lot of standby, which is pretty typical for me.
On a related note, G&E reader Dan4G wrote in to tell me about an upcoming 1800mAh slim battery ($54.95) made by Amzer, a company that also makes a fair amount of other EVO accessories. Amzer products for the EVO are also available on CheapDroids. Thanks, Dan4G!
