I don't start having issues until my phone is a 5% then the battery saver switches on, which in an of itself makes my phone lag like a youtube video on dialup, it also drops any video quality to that of an abstract painting.
Yeah, it underclocks the cpu to reduce the power consumption it drops mine from 1440mhz to about 600mhz it sucks, but if I leave the phone alone I can get three hours of standby time on 5% or 45 minutes of talk time.
Meanwhile my shit last an hour on 1% although it won't play music or videos it'll still let me play videos on YouTube. To be fair it's probably cause of the extended battery pack I have on it though
Phone was being laggy

Battery was at 13% then died immediately
