Battery life darn short?!

[gcianc]

You do believe the earth is round right? LOL

World phone sold with Vcast TV and prominently displayed in the WORLD TRAVELER HOTSPOT... any local shopping mall!

With 4x overprices Verizon ACCESSORIES!

Same with OZONE a $29-49 device probably going to 99% world travelers ROTFLMAO. All too dumb to TURN ON GSM when they sit on the 12 hour plane ride!

Happy New Year!

Then again, the Imagio is a WORLD phone and the vast majority of people that use phones are idiots as well and wouldn't know enough to turn the GSM setting on and off.

I still don't see a buy more batteries conspiracy though.

mine automatically uses CDMA when im in the US

I'll reinforce the answer given by other people -- the battery life sucks at first, then gets better and better as you go through charge cycles. My battery life now is perfectly fine.

I just switched to SPB mobile shell from TF3D and in very unscientific testing it seems to me that my battery life has improved -- could TF3D itself be a drain?

Back in the beggining someone that seemed like a battery expert said not to discahrge like this. He had all the numbers and readings of our type battery (i think he was a pro due to remote controlled cars). He said "our type battery actually works better if you constantly charge it". He said "the more you keep it close to fully charged the better". It was way back in the begging. I will try and find his post.

I know nothing about it. I'm just telling you what I read. But he did seems to know what he was talking about.....

here it is. It's from another site ( I don't know if we can say the name or not but you know who it is). I made the text red for the charging part i spoke of.

Ok so the battery life on the delivered phone is an absolute joke. Loosing 10-20% state of charge every 20min is not uncommon! There are two primary resons for this and it is NEITHER what you are doing, NOR what you are running's fault.
1) The device ships in GSM mode and there aint that many damn GSM towers in the US. This thing will connect to your local US cdma network and then search unendingly for a GSM nework on its other RF unit. Set the device to CDMA only mode and you will cut your average current draw to a quarter of what it regularly is. (youll also notice the phone doesn't heat up as much near the RF circuitry)

Settings->Menu->Phone Network Mode
Mode of operation = CDMA only

Changing nothing else, running no extra programs other than startup, having wifi enabled (no bluetooth). You should go from draining 10-20% soc/20min to 10-20% soc/6+ hours.

2) As I suspected some of the lipo stock they are sending out is old / was stored improperly charged. Go/call Verizon and get your free replacement battery (keep both). I fly ALOT of R/C and have been using big boy lipo's for afew years now. The stock battery is 1s 1500mah 1.5C lipo cell. (sorry, I was tired and wrong math in a previous post. The batt is 1.5c not 3.666C)

Now, a lipo should never be run below 20% soc, and longevity (charging/discharging cycles) is kept much higher by keeping discharges to a minimum (try to charge before 30% SOC, always). (please remember that the phone's meter may or may not be calibrated correctly, take the phone as only a guesstimate of what the battery is actually doing)
Testing the capacity of the cell revealed that pulling the battery down to 20% SOC (3.8v) and charging back up to 4.1v (vs an r/c lipo's 4.2v/cell) revealed only 917ma were replaced in the battery. This battery is a complete DUD and should have taken on average 1100-1150ma for a "blah" cell, to 1200-1250ma for a great cell.

In closing... Set the damn phone in CDMA only mode & get a free replacement battery, hoping its good stock! You can play with cabs that turn off push internet, ect to incrase battery life. But it's absolutely pointless until you get a good batt & have it stop searching for non-existant towers!

Do you happen to have any recommendations for a good replacement battery for the Imagio?

Sorry but no. I just remembered that post. I depend on these guys for that kind of stuff. I'm barely a step above amature....

I think NSA-Sailor found a cheap battery. But i don't know about good quality ones like that Battery Pro talks about

Sorry

[Ride33]

does the imagio have push internet? I know it has push email but i do not see push internet.

[sp3edd0g]

Yes it does. Ran through it when I was browsing the registry.

By the way, the first few posters are right. Battery life is getting better everyday. Thanks guys!
