New iPhone 4G in 2010: What battery life should be minimum?

By Gary Johnson - Jun 5, 2010

The battery life of the earlier versions of the iPhone has always been an issue with owners, but with the anticipated launch of Apples new handset just days away certain features of the next iPhone are becoming hot news.

A story by Derrick Johnson is reporting that the new handset will still not have great battery life; even though the handset probably will not have too much demanding technology it will only offer equal performance from other company’s smart phones.

We have spoken in the past about the battery on the iPhone 4G and the fact it is a lot bigger than previous models but will it be enough?

There is some help for owners of the current iPhone in maximizing their battery life. Keeping the device cool is said to improve performance, so try and keep it from places that will generate heat like the glove box of your car.

Updating the devices software or optimizing the phones settings can also add life to the device’s battery. With the expected announcement of the iPhone 4G next week what do you think the minimum battery life should be? Let us know your views.

    The 4g battery is in fact worse than my old 3 G! it sucks dry even when not in use. I have Tweaked every possible way to keep the background usage down. The processor is fantastic and thereon might be the 'sucking' problem….

    So let's compare first the 3GS and the Droid Incredible, and then the basic stats for the 3GS vs. 4G

    3GS is
    Talk time:
    Up to 12 hours on 2G
    Up to 5 hours on 3G

    Standby time: Up to 300 hours

    Internet use:
    Up to 5 hours on 3G
    Up to 9 hours on Wi-Fi

    Video playback: Up to 10 hours
    Audio playback: Up to 30 hours

    Android –
    Rechargeable Lithium-ion battery
    Capacity: 1300 mAh
    Talk time: Up to 313 minutes
    Standby time: Up to 146 hours
    (The above are subject to network and phone usage.)

    This is from their respective sites. I don't know how accurate the android is to the site, but the iPhone I know is pretty darn accurate.

    SO just commenting on the talk and Standby time, the iPhone would actually win out. It's over double the Droid Incredible on standby. Everything else, HTC doesn't comment on. HTC EVO has even worse battery life according to reviews. Especially with the 4G network turned on.

    Now the 4G will come with a 16% larger battery, an A4 chip that will help focus it's power and conserve battery life, and a possible solar cells in the glass/ceramic back

    If we just calculate the 16% larger battery, bare against the current 3GS specs, it'll be

    5.48 of 3G talk time (or 3G internet time) so just shy 6 hours
    standby time up to 348 or 14.5 days (original is 12.5 days) and the android is just 6 days.

    Wifi – 10.5 (instead of 9)
    video – 11.5 (instead of 10)
    Audio 1800 + 288 equals – 35 hours of Audio

    Again, not counting possible solar cells replenishing the battery throughout the day nor the A4 chip streamlining the battery, so we can hypothesize that these are low estimates and the battery will actually be much more powerful.

    My guess:
    I'd wager the audio playback would be probably be around 40+ hours. Which would be about a 1/3rd better battery life overall for each statistic (of the 3GS)

    3G talk/internet time 6.5 Hours
    16.5 Days Standby
    Wifi 12 hours
    Video 13 hours
