The new iPad 車拚 iPad 2
大家通常都用 iPad / 平版電腦做甚麼? 瀏覽網頁, 看電子書/雜誌, 看電影? 因為size 太大, 所以通常應該不會帶出去外拍吧? 我個人是都用來和家人 facetime 比較多, 但是, 非常想complain 的是, iPad 的front side camera 真的是爛的沒話說, 這次雖說是採用 Retina display, 但好像只有在 backside camera, 所以只有後拍有進步, 至於 facetime 仍是用front side camera, 所以我還是一樣氣……不過至少為下一代iPad留下一些進步空間….
今天的兩代iPad 車拚, 主要針對 camera quality, text quality, speed, power consumption.
大致上我們都知道 the new iPad 較 iPad2 贏在畫面品質, 速度快些, 也比較耗電 ( 之前 youtube 看到有人拿來熱茶 ), 但實際上拿到貨, 也是要來客觀的比一比, 已證實網路上有些批評是不是太過誇張….
What do you usually use iPad/tablet for ? Web browsing, reading ebook/emagazine, watching movie? I think you usually won’t use iPad to take photo too much because the size is not that small to carry all the time with you…. I personally use it to facetime with my family all the time. That makes me really want to complain the front side camera of iPad ( no matter which one) sucks! Even though they adopted the Retina display, but it seems only applied to the backside camera. Facetime is using the front side camera, which is not benefit from that at all! Well, at least they still have space to improve for the next generation..
Today we’re gonna try to compare these two generations from some perspectives, like camera quality, text quality, speed, power consumption. Generally speaking, we all know that the new iPad has better image quatily, faster speed, but also consume more power than iPad2. However, I still wanted to test it in person to prove if some web criticize is too over exaggerated or not.

10 分鐘過後, iPad3 掉到 97%, iPad2 仍維持在 100%, 我摸了摸兩台, iPad3 的確是熱了點, 但是還不到可以熱茶的程度…
剛剛又有朋友建議 ( 3Q! ), percentage 的確無法明確表示掉了多少power, 讓我簡單計算一下:
iPad3 的官方資料, 電池消耗率是 42.5-watt-hr, 約可玩10 hr –> 電池滿格應該有 425 watt-hr –> 也就是說, 1% 約相當 4.25 watt-hr 的電量
drop 3% ~ 12.75 watt-hr
( 但官方 Averate power consumed for 10 mins= 42.5 * 10min/60min = 7.08 watt-hr)
所以說, iPad3 播放電影的耗電量大大高出了平均值
iPad2 的官方電池消耗是 25-watt-hr, 約可玩10hr –> 電池容量應有 250 watt-hr (1% 算2.5 watt-hr)
但如果沒掉格, 不知道該怎麼算?
給各位參考一下, 25-watt-hr * 10min/60min = 4.16 watt-hr
如果說1% 算 2.5watt-hr, 那也應該要掉個一格了, 但卻沒有, 也許是有些unknown 因素影響了結果? 或者是說, iPad2 播放電影異常的省電?
我想應該要放個 2小時的電影, 結果會更好分析些……等我有空再來玩!
Based on iPad3’s official battery spec, 42.5 watt-hr, so the total battery should be around 425 watt-hr ( spec says can last for 10hr), that means each percentage represents ~ 4.25 watt-hr
drop 3% ~ 12.75 watt-hr
( Based on the official average information, the average power for 10 mins = 42.5 * 10min/60min = 7.08 watt-hr)
So, the conclusion is, iPad3 consumed much more power when playing vedio.For iPad2 is 25-watt-hr * 10 hr –> 250 watt-hr (full amount of the battery, 1% battery = 2.5 watt-hr) However, the bar didnt drop, I am kind of confused how to calculate it…
let’s say, for 10 min, the power consumed is around – 25-watt-hr * 10 min/60min = 4.16 watt-hr
So, theoretically, the bar should drop 1%, but it didnt….
