Average Customer Rating - 20 Reviews

Fast Shipping! Great buy!, October 21, 2010
This item arrived roughly 3 days after the order was placed. When it arrived, I did not use it until I was able to charge it overnight.

The first day of use, I tested the battery and turned on GPS, Wifi, Bluetooth all these while Pandora was playing for 3 hours straight. I did not use it much after that, and the battery was down to 10% around 630pm when I got home.

I was very impressed, it really lasts twice as long as the stock battery but, I was kind of expecting more from it after reading the reviews on here.

Overall - I am very satisfied with my purchase and feel like there is more room to maximize the battery.

Just got mine and I love it!, October 8, 2010
I ordered two of these batteries and I have to say I couldn't be more pleased. I had considered the Seidio 3500 battery, but I really hated the look of it. The back hump was just too ugly and wasn't worth it to me to carry around an ugly phone for a bigger battery.

This company doesn't lie when they say they are quick shippers and ship fast! I ordered each one a day apart and each one took a mere 3 days after ordering to arrive. That's amazingly fast for a Marketplace merchant, and wasn't using any expedited shipping company. And the shipping was pretty inexpensive considering the amounts for shipping I've seen others try to charge.

The pictures of this one seriously do not do it justice. It doesn't have a hump, but has a very sleek, attractive look. The thicker part where the battery sits is flat, and gently slopes down to the top and bottom edges. The camera and LEDs are framed by an inset frame, so to speak, that sits lower than the rest of the case, as does the kickstand access. Overall, it really doesn't add much bulk and, better yet, doesn't LOOK like it adds much bulk. The back almost feels like metal, and has a smooth coating that feels almost rubberized. Definitely not slick or slippery, its very easy to keep a light grip on. And a bonus is that both my son (who I got the second one for) and I have white Evos, so with the black backing, we now have Oreo Evos. :D

As far as the battery itself, I haven't had much of a chance to test it yet since I just got it yesterday. But it came with a 70% charge and I was away from home for several hours and used it non-stop, and by the time I got home, it was at 58%. I was accessing the forum through Tapatalk, checking 4 emails every 15 minutes, checking in on Foursquare and Yelp several times, used the browser to search for some information for about half an hour, texted almost non-stop, and several other things. I had background and auto sync both on, and for much of the time was in a building where I was constantly losing 3G signal and when I did get it, it was rather weak. So overall, I think it held up pretty well.

I'm very happy that I went ahead and purchased this one. Not only was it cheaper than the Seidio (actually it was the same price as the Seidio 1750, which I had ordered a couple of days before for my son and immediately returned unopened when it came).

The downside, of course, is that there aren't any cases available for it. However, there are some workarounds, so to speak. I have the Seidio Active case and while the hard shell back obviously won't fit, the inner rubber lining does. So it will have some protection. In addition, I have the Seidio Active holster. I was hoping the thickness of the new battery/back would make up for the thickness of the Active case, and that the holster would still work. I was right and wrong. The holster does not work with the extended battery when nekkid, but with the Active rubber lining on it, it *does* fit. Woot! :)

Unfortunately for my son, he has the Seidio Innocase Surface II, and the case doesn't fit. It does fit in the Surface II holster, sort of. It wobbles a bit, there's a bit of spare room, but it holds it securely enough that the phone won't fall out. (I hope he's right about that.)

So for those of you who, like me, hate the hump on the Seidio extended battery but want longer battery life without having to carry a spare, you should give this one some consideration. It adds just a small bit of size to it and not a whole lot of extra heft, and it looks very sleek and attractive.

Insanely good battery IF YOU USE IT RIGHT!, September 13, 2010
the reason why some people have given it one star is because they aren't using the battery correctly. when the phone shows a green light, it doesn't mean the battery is 100% charged--the HTC Evo detects 1500mah as fully charged, and the battery is 3500mah. this means whenever it shows green, it really means you're at 1500mah+ charge. you have to charge it longer obviously, that's how you get it to last through a 16 hour day like I did. charging it when you sleep is usually the best idea so you don't have to wait.

the battery life on this thing is crazy. i had 4G + GPS + Bluetooth and multiple apps running at the same time all day and it's still in the green zone. it doesn't look that much bigger, and I have big hands so the extra bulk is actually a benefit to me. it's like $20+ cheaper than that Seido battery.

in short? buy it, you won't regret! i'd give this 7 stars if i could. pay no attention to the one star reviewers who didnt use it right!

One week's test results - very impressed!, October 7, 2010
Day 1: Had 4G and bluetooth on all day from 8:00AM to 5:30PM. Used phone for music for 6 hours. Battery was in yellow zone, very impressed.

Day 2: 4G on all day, used GPS navigation for 1 hour. Used from about 7:30AM to 4:00PM, battery was barely still in green zone.

Day 3: Turned 4G off, used minimally. Lasted green whole day until night time.

Day 4: Turned 4G off, didn't do much except a little bit of texting. Lasted from about 9:00AM to 8:00PM and died.

Day 5: Turned bluetooth, 4G, GPS on. Read a book at the gym on the phone for about one hour, texted a lot. Started like 7:00AM and died 6:00PM.

Day 6: Didn't use it much this day, left it on charge most of the time. Was green all day.

Day 7 (Today): Used it from about 8:00AM to 5:30, was good for the whole day, had 4G on and off. Now in the red zone.

Overall this battery seems to last about twice as long as the normal one, I'm satisfied. It's a really cheap alternative to the other ones that cost $60-100. Buy it while it lasts, sometimes this item is back ordered. Luckily when I ordered it was available right away and I received it in like three days.

5/5 Stars, satisfied.

Works GREAT!, November 26, 2010
I was a little nervous about buying this battery. It was too cheap when compared to other companies extended EVO Batteries. The battery got here QUICK and the battery and back panel for the extended battery snapped on fine and work great giving me over double the amount of battery life on my EVO.

UPDATE :), December 3, 2010
I was comparing long and hard between this one and the Seidio Innocell 3500 mAh Extended Life Battery for HTC EVO 4G (Black) by Seidio...$50's VS $30's...between the 200+ comments for the Seido I ended up going with this one even with 14 comments....Hope it does like people have commented...my purchase was mainly due to the battery cover looked my streamlined

*****UPDATE***** I just received the battery and only took 3 days from date of ordering (regular/standard shipping)...SUPER FAST DELIVERY...didn't expect it so soon.....Packaging small, able to fit in mailbox...condition excellent just like the photo's showed..........now the big question?? DOES IT LAST :P ....... I know when purchasing these new batteries, it will take up to 5-6 charges to get the full effects....but so far so good, I charged it until it showed full and left it on the charger for 3 additional hours......and I'm a heavy internet user and app gamer.........and so far 5 hours and only half power used....wifi on, 3G on, 4G on, Wallpaper Live on, texting, internet, facebook, basically i'm running everything on....no problem with the battery :) ....... definitely a great buy for anyone needing more power :) ..... plus the case design looks way better than the Seido :P .... Get your now now now LOL .... for real great product :)

must buy, October 8, 2010
I totally love my evo but the one disappoint WAS the battery life until I purchased this battery...I use my evo heavily and I mean I'm on the net alot, bluetooth both for calls and playing music via car stereo, streaming media, texting and calling. my stock battery would only last me 2 hours, like I said I'm a heavy user. I got this battery and fully charged it and used it pretty much non stop. I took it off the charger at 9am and when about my day and around 11am I started heavily using it....streamed radio for about an hour and then streamed a two hour movie, texting, downloading apps via wifi, tethered my connection,...and it is now 4pm and it just got down in the yellow..still not dead...like i said, before my phone would've been in the red by the 2nd hour...7 hours now of heavy usage and it just barely in the yellow. This battery is completely worth it, it gives the evo the fifth start it was missing!!
