Guest keyvan Posted January 22, 2004 Report Posted January 22, 2004 Why does my phone die when my battery reads 38%? Anybody else have this problem? I am happy with the battary life, I usually get 2 to 3 days with moderate usage but the battery meter does not seem to be very accurate.

Guest mike-oh Posted January 24, 2004 Report Posted January 24, 2004 yeah, its a real pain in the arse!! You can turn it back on and it'l say 60 odd %!?!
Guest Jiff Lemon Posted January 27, 2004 Report Posted January 27, 2004 Yup - one of the first things I noticed - Mine seems to warn me its reached a critical level at about 60%! I can still talk for another half an hour though!
Guest phonesmarts Posted January 28, 2004 Report Posted January 28, 2004 mine too, except that every so often it runs out of batts in about an hour...after a full charge! i check up on it about 30 mins in, and viola -80%. another 10 mins and it drops (without any use) to 40%. then another 10 and it gives me a critical alert. it only happened twice, though. otherwise i get a good 3 days.
Guest ratcom Posted January 28, 2004 Report Posted January 28, 2004 Same here.. I have also noticed that if I leave the handset charging overnight (from 10%ish) on the USB cable my battery lasts less than if Id charged it with the wall outlet?! Strange...... BTW I get about 14 hours standby which I spend 2 hours everyday watching a different film at work... god I love my job nowdays :lol:
Guest awarner [MVP] Posted January 28, 2004 Report Posted January 28, 2004 I've never noticed a differance between charging via USB or Mains and I always get decent battery life.
Guest phonesmarts Posted January 29, 2004 Report Posted January 29, 2004 really? but is there a difference, from a technical standpoint?
Guest lawsonium Posted January 29, 2004 Report Posted January 29, 2004 Nope, The data part of the USB connection has no bearing on charge, it works the same as the mains adapter by simply supplying a voltage (5v from the mains adapter) which is the same output you get from a USB pin 1. I use my USB to power many things, even an ANTEC light tube I bought from eBuyer to light up my keyboard. However, the Motorola mains adapter delivers it's 5v at 450mA but I believe that a USB port delivers it at 500mA so has slightly more kick behind it, but not enough to make a difference. Anyway, this is a max figure and the MPx probably doesn't draw it's power at that rate. There is a feature built into USB technology known as the 'dying-gasp' but this is a failsafe if USB power is lost to shut down a device dependant upon USB power. So I can't see that this would be occurring, though if it were then your USB port could be running at 3.3v. This is unlikely and would undoubtedly cause the MPx to stop charging, so I am only mentioning this as a possible and not probable cause. Get a multimeter and see what’s happening :lol:
Guest ratcom Posted January 29, 2004 Report Posted January 29, 2004 Thanks anyway guys .... I think it was just a one off as now I am taking more notice I dont see a real difference.
