[Galaxy S 4 Q&A, Help & Troubleshooting] Apad121:
I had bad battery life. I installed GSAM battery monitor and I had bad screen on time of about an hour. I had just replaced battery but I still could only manage one hour sot.

I have Samsung Smart things and Life360, We chat constantly running in the background. My standby time on top of 1hr screen on was about 6 hrs. I could never get through a day- I didn't even think about it. Look at the screenshot and look at the averages at the bottom.

I installed Albe Lollirom as I heard about its excellent battery life and I decided to give it a try as it also came with a promising Ultra Power Saving Mode (From the S5) and a ton of new features.

I installed it and my battery life was noticably better. However I then proceeded to install Xposed with PowerNap, Amplify and Greenify. I whitelisted Smarththings and Life 360.

Stock S4 Lollipop ROM: SOT 1hr Standby 6hrs>>>>> New ROM: SOT: 2hr Standby 9hr >>>>>> New ROM + Xposed: SOT: 4hr 38 min Standby 20hrs!!!!!!!!!!!!!

I would deeply recommend it. It shuts down everything in background apart from the things whitelisted. I mean everything. Deepsleep Battery Saver was Okay when I used it but the Xposed Combo of PowerNap, Amplify and Greenify is far far superior!!!!!!!!!!!!! :)

Now I get a whupping 4hr Screen on time on top of about 20hrs standby! :) I would 100% reccomend this. I used to think that 3hr screen on time with additional standby time was fake and a complete joke on modern smartphones... Well I am pretty sure people just use their devices in a very specific way to achieve their statistics of 3hr screen on time but I am comfortably power using the phone to achieve these stats. What if we installed these mods and then tried to get better battery life? :):):)
