iPhone 4S Battery Tips
Well, I would like to make some comments of a set of settings that worked for me:
1. first of all I really don't know why but if I turn Wifi On during the night my battery drops like 30% in 6 hours of sleep, so try not to turn on Wifi unless is necessary, u can test it out but 3g works much better in standby than wifi in my phone.
2. i use all the normal settings: icloud on with push, facebook, whatsapp, location services all on, data on, notifications all on, background apps, etc...
But I found 3 things that improved me a lot my battery life: Wifi On only when needed, siri off, setting time zone off, and most important, Gmail with gmal setting in fletch at 15 min, without using ms exchange at all.
If u need the mail with push, i think is better wait for an update, but for now this solution has worked for me very well...
I attached my results, it said's that the iPhone has been plugged, but i only plugged to transfer 4 photos to my PC at work, so imagine the percent is at 3% or so.
I hope this can help someone with a problem like mine, this is my fourth day with positive results so you can check it out if it helps somehow...
Sorry for my bad english, Im not from USA.
Thank You
