打從第一部Android手機出現至今.我們已經發展出一套測試方法..可以精準的去測量電池使用時間.現在.我們以此用來測試幾部手機.並且分享我們的測試結果
Ever since the first Android phone appeared, we’ve been developing a battery test that would accurately gauge their endurance, and lend some objective data to our anecdotal tests.Finally, we’ve come up with one, and, after testing it on a number of phones, now feel confident in the results to share it with you.
最後測試結果如下表.Motorola2部旗艦機-Droid X和Droid 2表現最佳.相反的.有著AMOLED螢幕的其他機種表現卻落於其後.電力時間表現最差的是HTC Droid Incredible. 相較於Motorola Droid X有著7小時42分的表現.Droid Incredible的電力4小時33分即告用罄.
The results, shown in complete form below, may surprise you. Motorola’s two flagship phones, the Droid 2 and the Droid X, ruled the roost, but phones with attractive AMOLED screens clearly fell behind the pack. The worst phone for battery life that we tested was the HTC Droid Incredible, which managed an average of only 4 hours and 33 minutes, compared to the Droid X’s 7 hours and 42 minutes of endurance.
測試方式
測試方式本身很簡單..我們的web director “Avram”修改原本用於筆記型電腦的應用程式.”MoreLAPTOP”使其適用於Android平台.先打開手機的瀏覽器.連結60個最受歡迎網站其中之一.持續60秒在關閉它.然後在打開瀏覽器..瀏覽另一個不同的網站.以此方式不段循環直至電力用完為止.然後紀錄下使用時間.
How We Tested
The test itself is fairly simple. Avram, our tireless Web director, modified the Notebook batteries provide power to the system whenever it’s unplugged.
Learn MoreLAPTOP Battery Test we use for notebooks, and created an Android App that does much the same thing: It opens the phone’s Web browser to one of 60 popular Web sites, remains there for 60 seconds, closes the browser, then reopens the browser to next Web site on the list. It does so until the phone’s battery dies, all while recording the time elapsed.
在測試之前我們先作了以下措施.
1.首先,我們為每部手機下載2套免費應用程式”My Settings”和”Advanced Task Killer”.
2.啟動My Settings之後.並作以下設定.
3.我們將螢幕亮度調至百分之四十.並且關閉”手機自動亮度調整””
4.關閉.WIFI”.”藍牙””GPS定位”和”自動同步化”等選項
5.暫停螢幕自動關閉.此舉是為了確保螢幕永遠亮著.
6.在劉覽器方面.關閉”Flash:”和”plug-ins”
7.確保每部手機的收訊都在4格狀態
Here’s how we set up the phones before we tested them:
1.First, we download My Settings and Advanced Task Killer, two free apps that are useful regardless.
2.Then, we open My Settings, and do the following:
3.Turn screen brightness to 40%, and turn off auto brightness.
4.Turn off Wi-Fi, Bluetooth, GPS location, cell location, and auto sync.
5.Deactivate screen timeout; that is, make sure the screen stays on indefinitely.
6.In the Web browser, we turn off Flash support and plug-ins.
7.We placed the phone in an area that was receiving at least 4 bars of service.
測試結果
因為這是新測試.我們對每部手機起碼作了2次以上的測試.並且計算出平均值.
我們了解這測試沒有包含”文字輸入””手機通話”和”多媒體應用程式”但是我們認為這個測試給了每部手機在一個同樣測試條件下.客觀的測出他們的電力使用時間.
To the right is a screenshot of the app on the Droid X, after it completed the test once. Since it’s a new test, we ran it at least twice on each phone and took the average. We know this doesn’t take into account things such as texting, making phone calls, and using multimedia apps, but we feel it gives a fair indication of how long one phone will last compared to another under similar settings.
Droid X和Droid 2比之Samsung和HTC的幾種有更長的電力使用時間.而Dell Streak就算有著較大螢幕(5")
其電力表現也比大部分機種好.Samsung的Captivate和Vibrant都是Galaxy S I9000系列.沒有疑問的.2部首機的電力表現幾乎一致.然而.較小的AMOLED螢幕尺寸似乎並沒表現出比較好的省電表現.(比之Super Amoled).Samsung 的Epic 4G和HTC EVO 4G表現在平均值之下.而Incredible則表現最差.
Motorola’s doing something right: Both the Droid 2 and the Droid X lasted much longer than competing devices from Samsung and HTC. Even with its larger screen, the Dell Streak lasted longer than most smart phones. Considering the Samsung Captivate and Vibrant are essentially the same phone, it’s no surprise that their battery life was nearly identical. However, their AMOLED displays, coupled with a smaller form factor, seem to have negatively impacted their endurance. The Samsung Epic 4G and HTC Evo 4G (running Android 2.2) came in just under the average, and the Incredible, as suspected, fared the worst.
