So far I really am pleased with the batteries that came with this kit. Even before conditioning they were giving me more life than the OE battery and as they are used and recharged it appears the longevity is increasing. The wall charger is handy for giving them a good charge as well. The "key chain" isn't worth much and may as well been left out of the kit. The battery cover is good quality, fits well and isn't as clumsy to handle as I had feared it would be. The 4 star rating is for the silicone protective back cover and cheapo screen cover that comes with the kit. Neither fit well and probably should not be used because I doubt if they protect anything. Both get in the way of using or changing batteries on the phone, and the silicone cover sticks to any fabric making it difficult to impossible to get the phone out of your pocket! All in all the very reasonable price would be worth paying for just the batteries so, as I said, I'm happy and would recommend this purchase to anyone needing extended battery life for their HTC EVO 4G.

I am not a super heavy user, but the OEM battery was dying in about 8-12 hours. I've cycled these batteries a couple of times each and they are getting 1.5-2 days each. It is nice to be able to plug one in the wall while the other is in the phone. It came with 2 extended cases for the batteries, so there's a back-up in case one cracks. I find it is best to install the case bottom first, and the tabs line up easier. My only (very minor) complaint was that I could not use my fingernail to remove the case, like with the OEM case.

The silicon case protector is a nice bonus. It fit a bit loosely at first and seems to snug up to the phone slightly as it is used. You can then peel it off easily to change battery. It is rubbery, which is a pro & a con. It stays put on surfaces well, but makes it harder to get in & out of a pocket.

I can go back to the OEM battery & case if a want a little slimmer phone to carry around for short periods of time, but that's rare. I keep it freshly charged with the wall charger, just in case.

The wall charger does take about 4-6 hours to fully charge a low battery (15-20% left), but so does the phone plug charger. BTW: don't let a battery fully die. It is better to charge a half-charged battery than to let one die, based on the research I've done. According to NASA research, battery memory is mostly a myth, but all batteries wear out after so many discharge/recharge cycles and based on age. However, letting a battery die will shorten the life even more. If you don't use a battery, charge at least monthly (or check it in the phone to see when they get low), so it doesn't discharge completely.

Overall, I am quite happy with the purchase, especially at 25 bucks. I just hope they last a while.

Battery works great after battery deep charged a few times, remains strong thoughout day. External charger a plus for days where I need that extra power. Lifespan of my old 3500ma extended battery from Best Buy was 1.5 years before it started to get weak, these 2 batteries cost half price of 1 best buy battery, so this is the real deal, love the batteries.

After just the first charge my evo lasted all day. I had to find ways to kill the battery just so I could charge it again. I've had my evo 4g for a little less than 1 year and from the beginning have had to have chargers at home, at work and in the car just to try to make it through the day without the phone going dead. I'm a light user...I don't surf the web, play games, watch movies or even check emails on the phone basically because up until this point doing any of those things would shut my phone down due to low battery within a few minutes. By using this extended battery I'm finally able to see just what my smart phone can do without having to be within arms reach of a charger.

I almost never use my phone (I work from home and use a landline for 95% of my calls). Yet these batteries need to be switched out every day or two with no apps (or anything) runnining. If there weren't two and I weren't at home most of the time and able to switch them out, it would drive me nuts.

I have had this battery kit for a couple of weeks now. The battery performance is outstanding. The case and battery cover both fit. I had an issue with the battery cover, and YESOO sent me a replacement. YESOO sells a great product and has excellent customer service.

Great value for the price. carries a full charge past a day at times. No more plugging in the phone.
Just switch the batteries when they get down to 5 % and pop the other fully charged in battery your phone.
Then recharge the used battery again with the enclosed charger.

Its Great

Seriously, I don't know how we ever got by without this. Our original battery was replaced when we brought it to the Sprint store with the complaint that it wouldn't hold a charge long enough. Big mistake! The new battery was worse. After tons of research I learned about this battery and cover. We are loving it! We can use the wifi almost all day posting on FB, etc and when the battery dies we pop in the fully charged one and pop the dead one in to charge up. I love the wall adapter because evey mini usb cord we have has worked for maybe a few months. This one plugs right into the wall, no more cord issues! I would have bought this set for that alone!
