Battery Life: Unimpressive

The iPhone doesn't have a very long lasting battery. Before my iPhone I was a Blackberry user; my battery lasted for days. With the iPhone, especially while I'm traveling, I have to keep charging it throughout the day or risk a completely dead phone by 6PM. The Nexus One is worse.

To test battery life I ran the same suite of battery life tests I have been using in our smartphone reviews for the past couple of years:

The wireless web browsing test uses the 3G or WiFi connection to browse a series of 20 web pages varying in size, spending 20 seconds on each page (I timed how long it takes me to read a page on Digg and came up with 36 seconds; I standardized on 20 seconds for the test to make things a little more stressful). The test continues to loop until the phone dies. This test is designed to simulate a relatively heavy, but realistic data load on the phone. We're stressing the modem/WiFi radio, SoC, memory and display subsystems here. This should also be the sort of battery life you get when you are using any apps that use data (but not 3D acceleration). The display brightness was set to roughly 30% on the Nexus One and 50% on the iPhone.

The H.264 movie playback test loops a 480 x 208 632Kbps re-encode of Slumdog Millionaire until the phone dies. The majority of the device is idle during this test stressing the memory subsystem, video decoder, audio decoder and display more than anything else. The display brightness was set to roughly 30% on the Nexus One and 50% on the iPhone.

The talk time test measures battery life over the course of a conversation between the phone being tested and another phone. The conversation is actually an MP3 playlist on repeat played into the microphone of the phone being tested. The display was disabled.

Battery Life
 
Apple iPhone 3G
Apple iPhone 3GS
Google Nexus One
Wireless Web Browsing (3G) 4.50 hours 4.82 hours 3.77 hours
Wireless Web Browsing (WiFi) 6.67 hours 8.83 hours 5.62 hours
H.264 Movie Playback 4.70 hours 9.65 hours 6.67 hours
3G Talk Time 4.82 hours 4.82 hours 4.67 hours

 

Despite having a larger 1400 mAh battery, the Nexus one proved to have worse battery life across the board than the iPhone 3GS both in my tests and in my day to day usage. The only redeeming quality here is that you can easily swap out spare batteries, while the iPhone requires a 3rd party external battery if you need more juice on the go.

Talk time is lower than on the iPhone 3GS. Using the 3G data or WiFi connections both result in the phone dying faster than the 3GS. Even H.264 video playback discharges the Nexus One's battery faster.

I'm not sure if it's the AMOLED display, the Snapdragon SoC or just inefficiencies in Android but the battery life story isn't a good one.

Android does have a power consumption page that shows what percentage of battery drain can be attributed to various components in the phone (e.g. display, OS, specific apps, idle time). It’s not granular enough for my needs but it’s a great way of showing users, at a high level, what’s killing the battery.

    Sorry for repeating myself, but I really look forward to a test of the HTC Sense UI with either the HTC Desire, Legend (slower though) or Evo. I read several reviews and in every single one they were really impressed by the onscreen keyboard.

    I love the android platform. Now my last smart phone was the first Palm ever, so I could be thrilled with anything.

    The kicker for me was buying my android at Amazon for $49 (3 weeks ago), and now it's only $19!

    It's hard for me to grasp how much power is in my hands for $19. Sure I have to have a 2 year contract, but I'd have that anyway.

    As far as difference between mine and Goggle's? there's some, but the core functionality is present in both, just like an HP and a Dell computer with their built in thingy's.

    Cheers on a great review!

    Today on Amazon the Motorola Droid is $19.99.
    Amazing. I bought mine about 3 weeks ago at $49. I thik that it is great and a bargin at the price I paid.
    They are practically giving it away now. That tells you how profitable their $30/month data plan is.

    Wow, I've got to say: Super Job! Not only did you review the Nexus One, but you managed to simultaneously review Android, review the iPhone OS, compare the two's strengths and weaknesses, and describe ARM's role in the smartphones and microprocessor business (which I never understood). Long yes, but every page was well worth it.

    After reading all the hyperbolic tech news coming from Engadget, CNET, and PhoneArena, I was under the mistaken impression that Snapdragon was a clear smartphone platform champion, so I found it rather interesting that Snapdragon's integrated GPU was inferior to the PowerVR solution on the iPhone 3GS. If I'm not mistaken, this is the GPU that is used in the TI chip in the Droid, so does this mean that my Droid may be able to keep up with Nexus Ones/Snapdragons with 3D gaming apps, or will there be too much hardware and OS fragmentation for any app developer to create any optimized 3D gaming app for Android.

    This is going to be my go-to resource to provide to people who ask, "What is that strange object pressed to your face that isn't an iPhone? Does it cure cancer like the iPhone?" Trying to explain to my clueless tech friends that there are other viable smartphone options out there is an uphill battle, but one that may go a little easier now.

    Anand, I'll admit, this is the gist of what I expected from your article (I don't mean that in a bad way, mind you--). I own an iPhone 3G, and have for almost a year now. I like it, but I don't particularly love it. I imagine the 3GS would be a more fluid (and therefore more enjoyable) experience. For some reason, tech reviewers tend to not want to get rid of their iPhones for some reason. Even with a device like the Nexus One at their fingertips. I type this from a Motorola Droid right now, and I love it.

    I agree, I love the fluidity of the iPhone compared to Android devices (why must they be so powerful, but so choppy? That's my biggest complaint), but I love the feature set of Android even more.

    I also really want to know, why do you feel Android's pull-down notification menu is awkward? The first time I picked up an Android device and used it (never knowing about the feature), I felt it was very intuitive and a wise design choice.

    I completely agree with your general consenus that Android needs some polish, however.

    I absolutely love your website, reviews, and attention to detail. Keep up the good work! I just thought I'd share my honest opinion with you. Hopefully you'll have time to respond.

    Excuse my extra "for some reason" in that post. I was a bit distracted while typing up my reply...
  • Anand Lal Shimpi - Thursday, April 8, 2010 - link

    It's just an odd construct in my opinion. It's the only place in the entire OS that you pull something down to reveal more notifications. If anything I'd expect a tap to expand sort of deal, but the pulldown seems strange to me.

    I will say that after using it for a while, it has lost it's weirdness in my opinion :)

    Take care,

    Love the slide out keyboard - if only this was like the original G1 but with all the new horsepower.

    The G1 is the first phone that has tempted me away from a blackberry (well...almost) in 5 years.

    I have been a WinMo user for past 3-4 years, but I have to agree that Android, not WinMo7, is the replacement for Windows Mobile 6.5, and hence I will be jumping to Android phone (as of today I like the HTC Desire, but want QWERTY) from my current HTC Touch Pro 2.

    wow I cant believe how biased this article is towards apple. Almost every word you used when talking about the Nexus One had a negative connotation. Most of your 'negatives' towards the nexus one are completely false.

    The notification area for one--this implementation is 100% better than apple or palm and you think its a poor way of handling it? Wtf are you smoking.
