Pantech PN-820 Blog Day 3 — Battery Life


Last time, I wrote about using the PN-820 as a phone. It works fine, but the lack of Bluetooth voice dialing is a major downside. One thing I didn’t discuss was the PN-820’s battery life, but I will now.

The PN-820 comes with a 3.7 Volt 950 mAh lithium ion battery. Compare that to the 1130 mAh battery on my Motorola Q. The interesting thing is that the PN-820 gets much better battery life. I seem to get two days of use on the PN-820 under similar usage compared to about one day with the Q. I suspect that’s partly due to the PN-820’s smaller display.

On both phones, I keep Bluetooth on 24/7 and use a Bluetooth headset for my commute (about one hour each way). (Yes, I actually wear two Bluetooth headsets. Talk about an uber geek!) I also turn off incoming beams on both phones (which, on the PN-820, I think also turns off incoming Bluetooth). On the Q, I check E-mail every 30 minutes and have an RSS Reader running; on the PN-820, I don’t use the RSS reader, but I check E-mail every 15 minutes.

To be fair, I haven’t updated the Motorola Q with the MOL2 update, which I’ve heard improves battery life quite a bit for some. I didn’t think it was worth having to reload all of my data in the hopes of better battery life. I just make sure that I charge the Q every day.

For talk time, I found the PN-820 and the Q to be about the same. I called my office phone from the PN-820 and let them stay connected until I got a battery warning. The PN-820 was on hold most of the time (our phone system plays music while on hold, so there was audio going over the air). I got a low battery warning after 3 hours 14 minutes and the phone shut off after 3 hours 34 minutes. This compares to 3 hours 40 minutes of talk time on the Q using a similar test.

Of course, as I said, there wasn’t much real talking going on, so this test might better be called “connect time” than “talk time”. The PN-820 didn’t know it was on hold, of course, and would be picking up ambient noise during the test, so it’s similar to having somebody talk at you for over three hours.

Given those caveats, I have to say that I’m very pleased with the PN-820’s battery life. It’s not the same as you’ll get with a regular cell phone, but it’s good for a PDA, I think.

How does the PN-820’s battery life sound to you? Share your thoughts in the discussion.
