Improved battery Life

This helped replace my prior stock battery and lasts much longer that the OEM one was. I get a solid 3-4 hours of computer time now. It isn't super long, but I appreciate it.

easy to intall and to use. it preserves battery life when not in use, so that the batteries do not prematurely die.

It is so nice to not have my phone plugged in all the time. Kind of takes the "mobile" out of mobile phone. I play games, e-mail, browse, message,and text on this phone and the original battery just was not doing the job. I thought something was wrong with the phone. I used this extended battery all day and still had plenty of charge the next day even though I didn't re-charge it. I also bought a re-charger and another regular battery package. I tried the re-charger with this extended battery and it worked like a charm. Maybe better than charging the first time in the phone. The extra batteries are still in the package,don't need them now. To make it even better, the price was right..

It definitely expanded my battery life by a large amount since my old battery could do about 30 minutes. But after about 6 or 8 months it's now at around 45 minutes when it used to be 2 hours.

Solid battery so far. Had it for about three days of  a looong road trip. Practically, it charges your phone 3-4 times, at least for me since I usually start getting nervous about the battery around 20%.
Definitely adds bulk, but I'm sure you expect that, but for me function is above form. Do lots of work and leisure on the phone and usually need to charge it two and a half times a day.
Think of this as a power bank that you don't have to be tied to with a cord. Alternatively, you can have it handy and charged and only slap the phone in it when needed. Downside might be longevity of the connector. Case can be charged independent of the phone.
One main plus/ improvement is lack of an echo during calls that used to plague their previous Note cases. Definitely the quality improved.

I purchased the laptop with the shorter-life battery because I had been warned this one was bulky.  The fact the laptop doesn't sit flat can be annoying (a bit uncomfortable if you are using it as a true LAPtop for a long amount of time), but the battery life is so much better that I'm willing to put up with it.  I now actually stand a chance of finishing what I'm working on before I have to run for the cord.

Turned the 2 hours of battery life my three year old phone had left back to two days.  Not sure if it's genuine Samsung or not, but it's a huge improvement regardless.

This battery REALLY extends the life of your phone. The first three months I only had to charge my phone every other day. Now (3 months in) it seems to be dying a bit faster and I'm in the red after a day of use, but it still isn't as bad as my original battery where I would get a hour of talking/texting/internet before it died. Although it's a bit wasteful, I'm going to probably end up just buying more of these until I get a new phone in a year.

My phone now seems to be back to its original battery life.

Much improved: better battery power and storage, tighter plug-in, good buttons, nice reception. I would prefer a shorter cord.

With this battery and changing some settings I can go a whole day or more without having to charge my phone.  Thanks

These replacement batteries were sitting around my house for eight months before I finally charged one of them up and started using it.  The talk time has DRAMATICALLY increased from what I had been getting and might even be longer than the original battery when it was brand new.  I recommended these to a friend who was just about to go out and buy a new phone, and she is having the same excellent experience.  (Unfortunately, with us both now having such long-lasting batteries, there's little incentive to curtail our phone chats, and we waste way too much time talking!)

I bought my first Beats wireless solo used and was so impressed with the battery life, that I upgraded. I work some days 12-15 hours with the headphones on streaming Pandora and have yet to hear the low battery warning. The battery life indicator is a welcome addition, 5 lights lit up 1 to 5 depending on level. My original solos look goofy on me, so these have been more cosmetically pleasing as well.

Have had the battery for a short time and so far I have been pleased with the results. At first it didn't seem to last very long. But after a few charges the battery continued to get stronger. Now I can use the phone all day and still have more than 50% charge left. Now I never look or have to find a place to charge my phone. Could probably go 2 days without charging it.
Would recommend this battery to others

I've only used one of the 2 batteries so far, because the one that came with my phone isn't totally useless yet so I just alternate back and forth between the original and one of the 2 from this kit. The charger unit is indeed pretty slow, but I gotta say it seems so be the reason for my much improved battery life. I had thought my original battery was useless, but I find that after slow charging, its capacity is not much worse than the TrendOn battery. Also, both seem to have inflated charge values and short lifespans when I charge them in the phone with a cable, so now I almost exclusively charge through the unit in this kit. It's a bit irritating to power down my phone once a day to switch out, but it's WAY better than cursing at it hourly because of its failure to keep a charge. Plus, I can go from 10% to 100% in under a minute! (by switching to the one fresh out of the charger).
One irritation - don't know if I've mishandled it, but the LED on the charger no longer comes on. I can tell it's still charging because when I use the battery from it in my phone, it is fully charged. And it's not a big issue because I usually leave them for half a day or overnight anyway, so I don't need it to visually tell me as soon as it's done. SO, overall, DEFINITELY worth the ~$25 I paid for this, and oh well about the LED. I am so glad to be done complaining about my G5 phone battery!! After all, the ability to cheaply replace the original battery by myself is why I chose a G5 in the first place.

I bought the battery expecting it to be less than advertised, but still better than the original battery. I was wrong. It actually holds more than three times the charge of the original battery, I can now actually use the smartphone for what it really is, a small computer, not just a gadget that can do lots of cool stuff but runs out of juice in a couple of hours. Before, if I kept GPS active with google maps, the battery would be almost completely dry in under 2 hours. Now in 2 hours it dropped 28%, so I expect it to hold at least 6 hours, without any charging in the meantime.

The weight the phone has with the big battery feels good in the hand. It might not be good for everyone, but I have no problem with it. The TPU casing is well built, I even dropped it at some point on a hard floor, I could barely hear the bang when it hit the floor, it was that well cushioned.

Also worth mentioning, I saw no decrease in signal strength, for both the wifi and the 3g antennas. People I spoke with on the phone said they didn't notice anything different in the way I sound, so the microphone is unaffected also.

All in all, I am very pleased about buying this. It still remains to be seen how many recharge cycles it can deliver close to 7000mah, but it will still be visibly better than the original battery even at 50-60% of the current capacity.

Put in a Brinkman metal flashlight and it works better than original bulbs plus greatly improves battery life.
