Not only did I beat the Ars reviewer's time of 444 minutes (7:24), but I got the same battery life I did under iOS 6. I have never in my life seen an iPhone 5 get 11 hours of battery life. I once got close to 10, under very conservative conditions at the very beginning of its life, but on average it's been around 8. I'm not sure what sort of test Ars was running, but it doesn't reflect actual use very faithfully.
I just used the phone as I normally do during the day. A mix of Twitter, web browsing, twitter, texting, reading RSS feeds, and various other apps. I let the device regulate screen brightness by itself.
Now, there's a caveat to this. As I mentioned, I noticed worse than normal battery drain after installing iOS 7 last night. As a test, this morning before using my phone I turned off Parallax backgrounds (Settings > General > Accessibility > Reduce Motion [switch to 'on']). That seems to have made all the difference. I still expect Apple to optimize battery life in subsequent updates, but for now it may be best to switch that feature off if you want an extra 30-60 minutes of battery life a day. |
Well...
That's not my case.
I usually end my day with 40% or more and by 3pm CST my cellphone had about 20% battery. It was so bad that I actually had to turn it off so I can use it for an important phone call that I had to make by 5pm, few hours laters.
By 6pm it was dead!
I am re-charging it right now but I am really disappointed. One of the reason why I bought my iPhone 5 few months ago, after having a Galaxy SII, it because wanted better battery life. I'm on call all the time and battery life is key for me.
