HTC Evo 4G needs huge battery to keep battery life
A fresh teardown of the HTC Evo 4G by iFixit has revealed some of its inner workings and also given it an unfavorable comparison to the iPhone. Thanks to its 4.3-inch screen and 4G, Sprint's Android flagship needs a 23 percent larger battery than the iPhone 3GS just to get similar battery life to its smaller rival. The battery is also about 15 percent larger than that of a Droid Incredible and seven percent larger than the pack in a Nexus One.
The exploration does note that the Evo 4G is easier to repair or maintain than an iPhone. It's easier to remove the glass, and like "most reasonable phones," the back is removable to swap batteries on the spot.
HTC has followed Apple and the industry somewhat in including liquid damage indicators, though unlike any other company, one of its notifiers is on the battery. The decision could help Sprint identify problems where the battery and not the phone itself has gotten wet, possibly saving buyers a more expensive fix or replacement.
Components inside vary greatly from the Evo 4G's Apple-made competitor due to the platform and choice of network. Qualcomm has the dominant role as it not only makes the 1GHz Snapdragon processor but the CDMA baseband chip with built-in GPS and the power management circuits. Broadcom, which has played a role in both Apple and HTC devices, makes wireless chip with 802.11n Wi-Fi (albeit only up to 50Mbps), Bluetooth and FM radio.
