Sprint iPhone 4S Battery Life (Hint: Can Last A Full Day No Problem)

So how does the battery life of Apple’s iPhone 4S on Sprint’s CDMA network perform?

Read below to find out!

Here is my usage very first day till next morning.  Phone was charged to 100% then used regularly till it died at 1%.

Only about 20-30min talk time, and mostly just surf and netflix.  While on netflex, it’s amazing that the phone only used about 4-5% of battery for half an hour of video…  The thing I find it uses most battery is when I did intensive wifi and 3G speed tests thing droped 10% in less than 20 min (which you can see screenshot of the test result on my website here:

And some videos I’ve made compareing my old captivate and new iphone 4s sprint version)

3G speed test, AT&T vs Sprint, Indoor, less than ideal signals.

PS, I always thought sprint had better 3G than AT&T, but I guess not, it is a tad bit slower, however, coverage is definitely better at my office location (4 bars on Sprint vs 1-2 bars on AT&T… now just need to wait for the LTE deployment next year and the iPhone 5……

I hope this helps you guys in making your purchasing decisions.

Update

After a day of use, battery life has improved somewhat, lasting me at least 1.5 days of regular usage (internet browsing, maps, fb, talk and txt, no push emails though) See screenshot below:
