@Kelly Kearns Maybe it's your signal in your house. Mine is yellow when I have low signal. I noticed fast battery drain when I am at a low signal. Have you tried going into Airplane mode when you sleep? There's an option to go off 4G.
This is long but it's my history for the past 3 weeks. I am not tech savvy. Everything IMO. soo.. YMMV. I tried to get the same results where I got nearly 4 days of battery usage (probably 2.5-3 days under normal use). Initially heard someone get 2% during 8 hours overnight and tried to match but ended up losing my best charge messing with charging methods.
Current Phone Provider: SPH-L710 Sprint. Unrooted stock OTA JB 4.1.1 My data speeds are 1mbps for 98% of my area. Sad, I know. Had my phone for 3 weeks. We don't have 4G here.
Battery Draining Trend:
Currently inconsistent. ~2 days under normal usage YMMV. Approximately 1% discharge per 2 hours when not in use. The best (once) I've gone is 1% every 2.5 hours on standby. During on-screen use, I drain 1% every ~4 minutes and much more if I am downloading. This is during ICS and JB (now).
Battery Charging Method
Stock Samsung USB wire with LG Optimus wall adapter (Output 5.1V--0.7A)--I like slower chargers (Stock wall 5.0V--1.0A). Currently charging at 10% to 100% phone (powered off) for 3.5 hours. Pulled plug out. Wait for 15 minutes and reinsert until 100% shows up (~15-30mins). Pull plug and (optional - IMO ease battery strain) wait 10 minutes before turning it on. Will test out charging from 20-30% to 100% in upcoming charges. I pay close attention to how long it takes to go from 100% to 99%, 1% per X idle minutes, 1% per X on-screen minutes, how long did it take to charge and usually continue to charge the average time it takes. I associate short charging time (with the same charger) = bad battery/calibration. If it's been the same then, then a fast discharge must be from the the phone itself/app/corrupt file etc.
Personal Daily Activity
Mostly gaming and surfing the web. Data is always off. Wifi only when in use. 5-8 incoming text, 0-3 outgoing text; 15min-1hour online surfing/forum, 30min-1hour gaming, 3-4 2min calls; No social apps, No productivity app, No widgets, 1 battery stat app (ave voltage 3900mV, Temp 20C), 2 home screens
JB installation
I went from ICS to JB but did a full hard reset before and twice after installing JB. (Really tempted to do another hard reset) JB intially had bad discharge at 1% per hour with standby even though I charged to full when at 30% and then at 5%. To solve, I did a full discharge to 0% and recharge for 5.5 hours (taking out the plug and reinserting it at 2hr and 4hr because someone was hogging the charger so I dunno if it was fully charged or not). This gave the best battery charge (see screenshot nearly 4 days, wished I checked on-screen time too). One full discharge and charge, that's all it takes. Afterwards, more full discharges doesn't improve but might have worsen. Currently a charge last me 2 days. I believe I pulled the battery out for 10 minutes at one charging (can't remember if it helped but doesn't hurt to try ).

The oldest one shows nearly 4 days but the first 2 days of the 4 had barely any usage just to see how the battery drain. The last two days had fair amount of downloading gaming apps. I had used a 5.0V--0.55V Motorola charger.
My own question why does it takes 3.5hours to charge s3's 2100mah battery when it took 3.5hours to charge my Touch Pro 2's 1500mah battery???
