Extended Battery Test Begins

Up to 50 hours? You must not use your phone all that much. Still pretty awesome though. I have the extended battery, and I think I can get probably 15 hours of very heavy usage.

I just got my extended battery from Verizon. I'm testing it right now. 40% left after about 6hrs of use. The standard battery would have been dead by now. I work in a dead zone building, so web browsing is the killer battery in my case. My D1 would only last 2hrs! Lol.

Mines at 60% still and has been off the charger for almost 17 hours now with moderate use. Very very impressed.

Im still looking for a case though that fits this damn thing :/

 

I got the extended battery with the 60% off coupon that was posted here a while back. Running GummyJar 2.1, no task killer, battery-conservative settings. I'm at 13h38m unplugged, and still have 40% battery left, with a decent amount of use, including streaming Pandora for about 5 hours on wifi, an hour of MP3 playback and some mild web browsing. BatteryLeft estimates 7h15m left of similar use. Pretty impressed.

 

I got the extended battery on around 12/13/10 and it does indeed run quite a long time but the phone is a huge battery hog unless I don't use it. If I don't use it, the stand by time is several days. As soon as I start using the wireless or 3G for some browsing or play something like Need For Speed, it drains very quickly.

Just charged it off the wall charger and it's topped off at 4.200V. I'll use it "normally" (for me) and see when I have to plug it back in and report back. It's 9:07 on 1/5/11. Wireless is currently off.

By the way, the phone still runs cool for me but, when I was visiting my parents over Christmas and using their Wi-Fi (802.11g) which has a very weak signal, the phone definitely heated up while using Wi-Fi. At home, it's always cool but I have a stronger signal. Apparently the phone tries to compensate for a weak signal by increasing the power to send/receive.

 

It never occurred to me that that's why my phone would heat up so much. Thanks for posting. =>

Ok, here are some results:

Unplugged the phone at 9:07AM 1/5/11 at 4.200V

Used phone for one 15 minute call, some moderate web browsing, some market updating, a couple of low-powered games, one quick race in NFS Shift, a few minutes of YouTube videos, SocialWidget checking (FB) and checking the weather using WeatherBug several times. Screen is set to minimum brightness, sounds are middle with haptic feedback turned off on most things, and I set Airplane Mode both nights. The phone spontaneously rebooted once yesterday for no apparent reason.

The phone shut itself off at 11:50AM 1/7/11 at 3.123V (I knew it was going to shut off and checked the battery level minutes before it quit).

That's a total of 50h, 43m on the extended battery. To me, that's not great but it's at least a day longer than the stock battery. Over Christmas vacation I was at my parent's and I used it a lot comparing it to my brother's iPad and I had to charge it up every night I used it so much.

I'll probably run this test again over the next few days/weeks and see how it reacts but this seems to be what I expected of the extended battery. Anyone who says they use it a lot and it lasts 4 or 5 days is probably not being 100% accurate. Note that this morning it was at 30% and took almost 5 hours to drain that.

FWIW,

Kevin

 

Extended Battery and FM radio issue

I got my Varizon extended Battery last week and een testing it as well... I'm using my phone pretty heavy and get just slidly more out of it - maybe about 10-12h.

However reason I'm posting is that I seem to have an issue with the FM radio. I read somewhere on here that the FM radio will not work anymore when the larger battery is installed.

Anyone experiencing the same issue? Does anyone have a solution?

 

Yes I do use the cover which came with the battery...
