Well, I thought I’m done with my review of the HTC HD7, but here I go again talking about this smart phone. I promise, this is my last post on the HTC HD7 for now *cross fingers* but if I do own the phone, you’d just have to expect more reviews from time to time, particularly regarding the Windows Phone 7 (WP7).
The HTC HD7 comes with a 1230 mAh Rechargeable Lithium-ion battery which is said to last for up to 380 minutes (6.5 hours) of talk time, and over 380 hours of stand-by time. Yes, no mistake there. 380 hours of stand-by time. Thats like 16 days without having to charge your phone at all! I tried testing this time, but after two days (48 hours), I gave up. Come on, 16 days is a looOOOooonggggg time!
I did however did a test on other features of the phone. The test was done with the following fixed variables:
- The temperature is at the normal Malaysian room temperature.
- Testing was done from a fully charged unit until the warning ‘low battery’ was displayed.
- The battery was not changed, replaced during the duration of test.
- All test is done with all apps synced as ‘OFF’ except for the auto update by Facebook and the contact hub.
- Wireless, 3G and roaming is all turned ‘OFF’ (except for the 3G & wi-fi test).
- The phone was not used for any other reason except for the test required/mentioned.
Let me also explain that different features the phone has requires some tweaking in my test method as stated below:
- FOR GAMING EXPERIENCE – The same game is played over and over again with short 5 minutes breaks in between.
- FOR MP3 PLAYBACK – Continuous playback with different songs using earphones.
- FOR MOVIE PLAYBACK – Continuous playback of the same movie using speakers.
- FOR WI-FI/3G USE – Left switched on without any use of any applications.
- FOR NORMAL USE – Occasional tweeting and use of basic apps related to the internet once a while (around 3 hours)
With that cleared up, here’s the graph of the battery life based on my personal test.
As you obviously can notice, the battery is longest on wi-fi on standby mode (without use), but the battery drains quickly when you use the phone continuously. Regardless of that, the phone still last longer than certain other smart phones. And before I forget, a good full charge takes about 2 hours.
Please note that the test I’ve done is only accurate at my test time.
