I'll throw kudos to Juice Defender as well. I went with the full premium version shortly after installing the free one. I has at times doubled the battery life in my EVO 4G. There's a learning curve to the initial set-up, but it's an app I won't do without.

I have a splash portable charger for my OG EVO .It is smaller than the phone and can get 3 full charges before it goes dead,and can charge all my other devices! This makes more sense if you worry about battery life and you don't end up with a drawer full of old batteries for phones.The whole imbedded battery is no big deal for me.

Hello derick1073, look about eight posts up. An alternative type charger may be just the thing you're looking for. they have battery, fuelcell, and solar type out there.

I agree, people make too much of needing a spare battery when there are alternate ways to get battery life.  Anyways, looks like Evo LTE has been delayed so...  http://betanews.com/2012/05/16/apple-patents-block-htc-one-x-and-evo-4g-lte-from-u-s-market/

Re: What now? HTC EVO Imbedded battery! No way!

This is probably a really dumb question, but I guess I will ask anyway.  I believe that we are instructed to fully charge cell phone batteries before first use, and fully deplete/recharge the battery for at least the first few cycles.  Supposedly this will allow the battery to take a better (i.e. fuller) charge, and improve battery life.  I do know that when I let my old media player sit too long without a charge, it would never take a proper charge again.  Obviously phones are shipped and sit in inventory for extended periods all the time, so I doubt there is a significant issue.  However, I am wondering if anyone is concerned about the extra time our Evos are sitting without getting the initial charge, especially since the battery is not replaceable.  Is this a non-issue?

Lithium-Ion Polymer batteries do not have a "memory" that older batteries exhibited (i.e. Ni-Mh and Ni-Cad technology).

I've always had good experience with information from here in the past: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries

Simple Guidelines for Charging Lithium-based Batteries

  • A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.
  • Charge at a moderate temperature. Do not charge below freezing.
  • Lithium-ion does not need to be fully charged; a partial charge is better.
  • Chargers use different methods for “ready” indication. The light signal may not always indicate a full charge.
  • Discontinue using charger and/or battery if the battery gets excessively warm.
  • Before prolonged storage, apply some charge to bring the pack to about half charge.
  • Over-discharged batteries can be “boosted” to life again. Discard pack if the voltage does not rise to a normal level within a minute while on boost.
