> How often are you not near a source of electricity at least once a day?
It's a major issue when traveling, which is when you want your fancy smartphone mapping features the most. If you want to be able to use it later in the day, you have to be careful not to use it too much earlier.
I've been pleasantly surprised with the Galaxy Nexus battery life though, which usually lasts me just about two days.
Get up from hotel room and leave before 8 to make it to the conference. On the move all day till it ends around 6. Starving. Time to Yelp up a good place to eat in this town and map my way there. Oh wait.
God help you if you took pictures or used your map application much during the actual course of the day.
The day smartphones can allow a user to use every core application heavily (maps, email, voice, camera) all day from the time they leave their bed in the morning till the time they return to it will be a great day imho. It isn't every day that you're travelling for business, but it's these users and these situations that feel the pain points of battery life the most. It happens to millions of people all the time, every day.
I think you missed the jab the parent post took at the grandparent post.
Just because you don't think you need x amount of hours of battery doesn't make it useless for everyone else.
Also, people who question why do you need more? Because you can do more things. Our usage of smartphones is increasing in many ways and improved battery life should not be counted in terms of how many hours of talktime it will give you, but how many hours of <insert heavy battery eating application here> use it will give you.
For one, when travelling, you can sometimes go for a while without having a chance to plug in and charge (due to not being on one place for long, bags being inaccessible, not having outlets on a long plane ride, etc).
But even when not travelling, I will sometimes forget to plug my phone in one night. It's really frustrating when it dies the next morning before I have a chance to recharge it again.
The unfortunate irony is I need my phone the most when I'm away from my computer for long periods of time, and these are the only times I run out of battery. I run out of battery maybe three times a year, but when it happens it's often a pain.
