Bests & Worsts Reviews from Amazon

Something to add to the old saying, you can never be too rich or too thin, you can never have too much battery life. I often run a 4400mah extended battery, and when I travel I carry around a 16000 Mah backup battery in addition to a car charger and wall charger. This battery is going to change what I pack. I ran the phone with gps running screen on full brightness, Wifi, Bluetooth, and CPU load, and it is still going 12 hours later, I'll upload some pictures both of the battery and how long it lasts. I regularly get 35-45 hours on the 4400 battery so I would anticipate topping 70 hours with this battery but I will update with a real world runtime once I get a chance to fully charge it again. From 15% it took over 8 hours on the stock 1A charger, which makes sense when you consider that the phone will use some of what is being put in. The size with the provided case is comparable to an Otterbox case (see pictures) and slimmer than Seidio Active extended case for the 3500-4400 MAH batteries. The case has a slick back which allows it to slide in and out of your pocket easily and the sides are textured so it does not feel like it will slide out of your hand. It does slide easily, however, when placed on it's back on a desk or in your lap, so keep that in mind when you are getting out of the car or setting it on a counter. The case itself is very nice and seems to be of a much nicer and thicker material than the much thinner TPU case that can be purchased for the 3500-4400MAH batteries. In fact it seems thick walled enough that it would provide good protection from those times you say "whoops" although I won't be testing that. One last thing to consider, This battery comes from a company with a proven name and customer service to back it up. If you check anywhere you will see that they do honor their 18 month warranty and they have been around long enough to have a proven track record. I do need to add that this battery was provided for me to test and review as a part of the Anker power user program. My review fairly represents my experience with this product. Update: 3 days 19 hours runtime on second charge!
