I don't see a reason why people would lie about battery life on a forum, but since you don't seem to believe anyone, I'll take a screenshot when I'll have to charge my phone.
He is right you know, some people do not lie but omit facts like using their phone as a statue, ok I'm exaggerating but what he is talking and so do I is real usage with all it's functionalities enabled.
For example, I always have on
- Wi-Fi with all features on (wifi sense etc)
- Bluetooth having the DT-903 nearby always for notifications.
- NFC
- Location On
- Cortana On
- Auto Brightness
- Outlook + Gmail
- I am always in Roaming
- Find my phone ON
- Hey Cortana ON
Allowed in background:
- Skype
- Instagram
- Facebook
- WhatsApp
- Twitter (official app)
- Store
- Weather
- Pin.it
- Disqus
- OneDrive
I frequently use:
- Tubecast (full hd clips) like 20-40 min per day
- Skype 3h per day cumulated usage, only text
- WhatsApp (few minutes only)
- Instagram (only browsing) 30 min per day
- Camera , few pictures per day
- Here Transit 2 times per day
- People app where I check for news on facebook and twitter.very often, like each time I unlock the phone.
- Internet explorer quite a lot
- Pin.it browsing pins
Using all this it goes down in 6 hours.
Now don't tell me that having all these on and my pattern usage, you can juice out 2 days because it's completely bullocks.
