Replacement 3.7V 3800mAh Extended Battery w/ Back Cover for Samsung Galaxy Nexus Prime i9250

Pros: - High capacity battery - din't do any comparable testing but the battery life extends at least twice comparing to the battery included with the phone - Low price comparing with other alternatives (some reaching $99 price mark -fits nicely into my docking station: http://dx.com/portable-charging-dock-cradle-usb-data-cable-for-samsung-galaxy-nexus-i9250-black-116667

Cons: Bulkier back cover (delivered with the battery) higher weight of the phone

Other: For those who does not mind having a bigger phone it is very good alternative.

Pros: This replacement battery lasts, as expected, longer than the stock one for that phone

Cons: The battery is a little too big for the actual capacity. The phone gets really huge on the back side. I also expected it to double the battery life of my Galaxy Nexus phone, but it didn't that much. It sure lasts longer, but it still drains quite fast.

Other: Overall, the battery is quite nice. Its big, but not really heavy. I got used to the new back cover after a while, although the phone now looks a little big more ugly, at least now I can use the phone from the time I get up and the time I go to bed again.

Pros: Extended battery life! Perfect for example when traveling with much GPS usage.

Cons: Makes the phone bulkier and a little heavy, but it is worth it. No NFC (as expected), this makes me use another battery when the extra power is not needed.

Other: Buy it if you are going to use your phone more than usual from time to time. Or if you are not worried about the extra size/weight/lack of NFC use it as you day-to-day battery.

Pros: The standard battery for the nexus is 1750 mAh and this is 3800. I am used to having to charge my phone every night and I am now using this battery for the second day with 55% battery left. It really extends the time between charges and I use the phone a lot. Back cover fits nicely btw.

Cons: The phone gets big and somewhat heavy. I expected that and with that big battery I don't think there is any way around that issue.

Other: Very good if you want the phone to make it through a weekend or so without having to charge all the time. The phone gets bigger but it's not that much really.

Pros: - cheap - charges fast - back casing fits perfectly

Cons: -looses charge easily if left out over time - not really 3800mAh, got about the same time as my OEM 1800mAh battery - THe battery is quite large, almost double the oem one

Other: Considering an OEM battery is roughly 10 times the price of this, it's a nice backup for when you forget to charge your phone or something, but won't recommend it for daily use

Pros: The cover snaps perfectly to phone. Battery lasts way much better than stock. Screen time is around 6 hours. With stock I was able to get 3-4. Looks pretty solidly built overall.

Cons: Nfc probably does not work. Looks a bit ugly and geeky. Charging via USB takes eternity, using AC is highly recommended.

Other: If you need extra battery life and do not mind a little thickness, go ahead and buy this.

Pros: - Provide extra long hours phone usage; don't need to worry about running out of battery - Good quality, especially for this price - Make the phone larger but I like the new size and weight of the phone with this battery

Cons: - The cover is hard to remove after attaching to the phone. This makes it harder if I want to switch back and forth between this battery and the original one.

Other: This is the battery I would recommend to all Google Galaxy phone users. It makes using the phone become such joyful experience.

Pros: In my experience, lasts for almost 3 days with moderate usage and almost a day with heavy gaming usage. Battery length reminds me of the time before phones became "smart" and lasted for several days before recharge.

Cons: For those who enjoys the slim profile of the Galaxy Nexus, this will be bulkier and noticeably heavier. Also, I had trouble setting in the custom back cover, but that is not an issue anymore. Another con would be that, obviously, the increased size will not allow cases or some windshield mounts to fit.

Other: If you are not cool with battery drain on your Galaxy Nexus, this will definitely help. Might as well; look how inexpensive it is!

Pros: This battery lasts twice as original and significantly extends phone working time without charging. Good price; Everything you need is included - it takes one minute and you are ready to go! NFC is working without any problems.

Cons: Phone gets thick and bulky; Cover quality is lower than original; After using it for 6 months, capacity slowly decreases.

Other: Good product for this price!

Pros: Lasts 2 days of heavy usage; Great for holiday trips when you take lots of videos and photos; Also great for gaming / watching videos Back cover feels solid and one-piece Awesome price! You will get used to the increased size an weight. No big deal.

Cons: Bulky, no NFC The very steep discharge curve near 20% charge may surprise you (i.e. went from 20% charge to zero in less than an hour)

Other: Worths every penny!
