So I kept seeing threads with Android users saying that iphone users don't really get 6-8hrs of usage time on their iphones, and that the usage on the iPhone doesn't necessarily mean the screen is on. Well I decided to charge my phone to 100% and leave the display on the whole time. I tried to do all the things I normally do but ended up doing more just to kill the battery faster. I was on Wifi most of the time since my job also has wifi. Well here's my results from my iphone 5s This is about what I normally get This is with the display on all day at 50% battery This is with the diplay on all day at 1% battery Things I did on phone: talked for 30mins texted twitter used Find my Friends Played a couple of games browsed the Net a lot watched youtube videos (don't remember count) watched a episode of Family Guy on Netflix played music for about 10mins checked weather read email and sent email opened apps and to read content So my battery usage lasted about 4hrs more with the display on the whole time. I don't even know how that is even possible, and I did more stuff then normal. My display brightness is at 30% if anyone wants to know.
