Love long battery life

Replaced an HTC Evo which did not last the day when using throughout the day. The Razr Maxx battery life is outstanding; goes several days without charging.

Works very well and battery life is better than expected. If needed you can keep it plugged in while using it. Well worth the price.

I love these conects easy and quick really long battery life, cant remember when i last charged them!! They aren't super loud as some of my previous ones though but loud enough. Took a star off because the volume buttons didn't work with windows 10 or while watching YouTube on my iphone 6s which kinda sucks

Great long lasting battery. I love how it always connects instantly with my iphone 6. When turned on, it states how much battery life is left. On the receiving end, calls are clear.

Long lasting battery, very thin, good large screen & all the Kindle convenience I love. When I am working late and run out of audiobooks to listen to - I can download a new one in minutes even in the middle of the night.

I love how long the battery lasts.  I wish they would bring back the MP3 capabilities of the earlier versions so that you could still plug in headphones and play tour Audible books on it.

I have used these for almost a year and love them!!  I was concerned the battery would fail quickly because there isn't room for a big battery.  Nope.  The battery last long time between charges.  My only grip is the color isn't what I hoped it would look like in person.

I notice that my battery life last longer if I just use a regular plug.  However this is convenient and very cool, I just would prefer a longer battery life for my phone.

I just received this today and I had to put it on because I was just curious what kind of life I would be getting.  When I just popped it in, it was pre-charged at 55%. Typically, my old battery (3500 mah) would last about 4 hours of heavy usage.  My term of "heavy usage" is watching netflix or streaming something on Navi X while on wifi, keeping my GPS signal on, and media casting to my TV with a bluetooth to my speakers.  So far, it's living up to my expectations.  The battery was able to survive 4 hours of heavy usage and still had plenty of juice (about 14% when I was done with a 4 hour trial).

I attempted to charge this phone and it does take quite awhile to charge it compared to a standard battery.  I'm sure it's probably because of the size though.  I think I'm going to have to take some snap shots and turn it into a video review so people can see the thickness of this thing.  Problem is I don't have a camera other than on my phone lol. Anyways, I thought my phone was big before but now.....it's bigger lol.

As far as the case though, I'm a little afraid to carry it around.  It's a thin plastic that feels easy to crack if dropped.  I'll have to start looking for a case if I decide to continue to use it.  I'm not too fond of the size but if you someone needs a big battery because they are tired of charging their phone constantly then this is it.  Typically on a regular day with normal usage - no gps, wifi on, bluetooth on, no candy crush, maybe 1-2 of internet surfing through out the day, my regular battery can last about 12 hours.  I will have to come back to this review because I feel like I need some more time with it but I expect it to last at least 30-36 hours straight without a charge.

I received this item for an honest review and it really took me awhile to really feel this one out.

Love the Battery life and clarity of sound, but also enjoy all of the compatibility features with cell phones and TVs. I still feel like I haven't even broke the surface on everything this phone can do.

I love not having to move the mouse all over my desk to move the cursor on my screen.  This mouse is very comfortable to use and the battery life is unbelievable.  I use one at work and at home.  The one I use at work has had batteries last 2+ years, not bad for something I use every day.

Amazing mouse and great battery life. I've had this a few months now coming up on a year I believe and I to my knowledge I believe I change the batteries once.
