Thank you.
People on this forum forget they're probably not the norm. My dad gets 2 days from his 5c - he's very light user, but I imagine there are more him then there are of 'us' on this forum. I get about 12 hours from my 5s. But I have an office job and I have a dock on my desk.
Your estimates are on the next iPhone are interesting.
Anandtech shows the 'tiny' battery in the 5s competes quite well against the 3000 mAh Android flagships.
Actually, the whole point of a Smartphone is to use it for tasks that a normal Nokia cannot do. If I use my phone very lightly, I can make it last over 3 days maybe. Does this mean that the phone battery life is enough?
Apple is promoting gaming on its platform. It is promoting an always connected device willing to talk to your health gadgets, laptop and tablet in real time. If I don't use any of this stuff and just use it to make 5 minute calls I am sure it is enough.
If I use it in a normal smartphone scenario, connected to my smart watch, connected for some time to my car. Listen to a little bit of radio or podcasts, read the news, interact on facebook, whatsapp, etc.
It dies. Does not last a day.
Your Anandtech charts are interesting and they have been in the business since ages and I follow their reviews so I won't say they are wrong.
All I know is that on my Nexus 5 (with a custom rom and a custom kernel), my daily habit of reading the news and responding to messages when I wake up takes about 10% of the battery (down to 90%).
Doing the exact same thing on the 5s takes it down 22% (down to 78%).
Why?
