Another vote for the Seidio 3500mah extended. Best purchase for my EVO ever. Especially if you tend to overclock on occasion.

Seidio 3500 is Good

---

I used the Seidio for a year, it was good, now its kind of weak, I got this one a week ago and its been pretty good for me.

I have the Seidio 3500Mah and love it. Before it I could barely go 8 hours on the stock battery and now can easily go over a day and a half, even after 16 months with it. Got it from Amazon and would definitely get another if this one dies.

Sprint 2600mah

---

I still have my Sprint 2600mah, the 2 back covers are a nice touch, since you can switch between black and white.
I hardly use it anymore just because I changed jobs and now have access to charge my phone whenever I need to, but it was great for when I needed it. I would barely get through my work day with the stock battery, but I was able to get through 2 days usually with my extended battery.
Now it just sits in a drawer, lol.

How about the evo 4g plus guys. Which one is best?

Trident makes a rugged case in the Electra series that comes with a 2800mah battery. I've been using it for sometime now and still get about 3 days on a charge.

Agree - I've owned the SEIDO 3500mAH extended battery for almost the life of my phone, and it's been excellent. I've mainly run CM on it, and it lasts nearly 2 days with moderate use. Definitely recommend it.

I found some batteries for the evo
