Works great, I actually love the beefyness it adds to the phone, last 2 days no problem with normal use, 3 if seldomly used 1 if used constantly for 12 hrs

Pros:- Super long battery life: Can easily go 2-3 days on a full charge with moderate

I get 2-3 days battery, huge improvement

The close to 2 days without charging,Only problem is it take 8 hours to charge 75% or less

I can't claim three days of use, but where I work, my phone drained so fast that it was completely dead by lunch

I can happily say I would get 3 solid days of fairly heavy use from this battery

Great seller, really makes my day easier To Not worry about recharging.

not 3 times the battery life as advertised, but a good full 2 days with quite a bit of texting and fb use

Excellent battery life, lasts a good two days with no charging and steady use including GPS.It does seem to negatively affect wifi signal, though this has not become a significant problem.

I can go for like 3 days using my phone normallty without having to charge it

Anker customer service is awesome!This battery lasts me 3 days where the original battery only lasted me half a day

Can now go 2.5 days as opposed to running out of battery everyday!

Lasts all day long and well into the night.

it works great, it lasts all day now where i use to by 9 am have to plug it in and again around 3 just to get through the day

I love it, 3 days of power for a high user is great.

I use the OEM battery for every day use to work.

I used to be tied to my phone charger, carrying it with me wherever I went so that I could assure a whole work day of phone usage

Just glad the problem showed up the second day

last all day and night, make s the phone easier to handle and grip.

Google how to calibrate your phone's battery percentage if this issue arises!My battery lasts over 3 days per charge.

On a good day I cram in 4 hours of heavy use (Netflix and PPSPP gaming)

5 days vs twice daily (original battery) is definitely an improvement over the original battery performance.

but I completely loose signal numerous times a day and have to reboot my phone to get signal back

but now I can last long enough for a days worth of casual play.

this phone last a good 2-3 days but its a surviver when on it's last percentagesRead more

I charge it at night and it is good all day, I honestly think it could go for 2-3 days

It works great, I can go 3+ days before a recharge.

It did not die until 8:40a the next day

A full day is no problem for this battery

3 days worth of battery on this thing

Two days easy if on continuously and used heavily

Amazing my phone lasts 4 days!

Love the 2 days plus of heavy use time without charge

I use my s4 without even thinking about power now, i don't need to plug in and worry about battery percentage, i can play a game, use the gps, forget to plug in and charge at the end of the night and no worries, this sucker can go 2 days!

Have a nice day.

I can get a day out of a single charge, and the battery refuses to charge above 90%

I start the day fully charged and with no change in phone usage aka turning off functions to conserve battery power, I end the day at 70-80%.The case protected the phone against an accidental 7ft drop from the top of a work cabinet

I can really enjoy my phone, up to 2 days without charging it

Lasts all day no problem

First charge lasted a week then after that it seemed the battery life died down like crazy to like 3 days almost made the no screen protection not worth it anymore

Most convenient is not/not being tied to an electrical outlet every day.

The battery and accompanying case is bigger, heavier than the phone's original, but it is powerful, lasting two days between charging.

2 to 4 days stay .... solid ...

The battery life is over the top - over 2 days, I use it when I travel

So in theory I can go 5 days without charging if I am conservative the last day

The phone now works exactly as it is supposed to!If you remember Nokia phones from a decade ago that lasted a week on one charge, this battery will remind you of that long-forgotten feeling.

I didn't see any changes in performance of the device or anything that is not working as it was before start using the battery.

lots searching during the day with the screen as bright as can be for 3-4 hrs

Works great, only complaint is that the case doesn't hug my phone as tightly as I would like.

I do recommend this battery as I can go days without recharging.

An awesome battery better than zerolemon (y)
