Default Review of Anker 5200 mAh extended battery w/lots of pics!!!

This is a review of Anker extended 5200 mAh battery for S4:

With a lot of different phone battery releases, Anker established themselves with a strong and dependable reputation. I used their battery with my Note 2, so testing their extended with S4 was no brainer. Although Anker doesn't manufacturer their own batteries, each one features grade A cells and full CE and RoHS certification. I know these guys stand behind their product and make sure it passes all the required built-in over-load and over-voltage protection. And to back it up, they always include 18-month warranty and a top notch support. This particular battery is no exception.

It comes in capacity of 5200 mAh which is a double of OEM 2600 mAh from Samsung. The battery has a built in NFC, just like a standard one. Obviously, double capacity comes at a price of double thickness and double weight. I confirmed that by measuring original battery to be 44g (1.6oz) and 5mm (0.2in) in thickness, while extended one 90g (3.2oz) and 11mm (0.47in). No matter what you find on ebay claiming capacity of more than 5200 - I would never trust it because it's physically impossible to stuff more cells into that footprint.

The battery comes with a cover that doubles the thickness of the phone. The one I received had a very nice deep blue color, and a smooth finish. I did find the finish to be somewhat on a slippery side. The good news, you can easily find extended tpu honeycomb case for S4 on ebay for about $6. That will add more grip and give your phone extra protection. I just found that Anker also offers their own TPU case for S4 ( AnkerŪ Glaze Case for Samsung Galaxy S4 with Flexible Matte TPU - Super Slim Fit of most Durable Case - Retail Packaging - Blue: Cell Phones & Accessories), but do NOT get confused since this one is for a standard 2600 battery/cover which they offer as a replacement for OEM.

Performance of the battery was very impressive. I captured screen shot of it below. I run a stress test of keeping phone display at full brightness, no time out to shut it off, and playing HD movie in the loop for 10.5 hours!!! Along with web browsing, running some apps, and making phone calls, I had it running for over a day on 4G (no wifi) and still had 16% of battery left. That was not a light use, almost 11hr of hd movie at full brightness is not a joke. Overall, definitely a great battery to provide you with some extra juice!!!
