I have a MOTO w755. I use a home charger at night to charge my phone. I was at work and my phone was showing a small sliver of battery life and was blinking at me LOW Battery LOW Battery. I don't have a car charger or wall charger at work. I do have a camera here though that has the same size plug as my phone so I turned off the phone, plugged the cable into my phone and plugged the USB end of the cable into the computer. After 10-15 seconds the phone powered up and said unauthorized charger. I left it plugged in for maybe a total of 30 seconds and I got a fully charged battery!! it's been on for 5 hours now and it's still fully charged! Anyone have an explanation for this? Is this hurting or shortening the life of the battery? I mean a 30 second charge is pretty cool :biggrin:
If it said it was a full charge I would not believe it. Something is up with that battery, and possibly the phone. The energy required to charge that battery to full capacity in 30 seconds would probably melt the battery, and possibly the phone as well.
Well.. I used the phone and it worked perfectly. It was on for 8 hours after that and had 3/4 battery life still showing. I didn't believe it either but it stayed charged and made phone calls with no problems.
I'm thinking that some other error came up where it was misreading the battery charge level, and it was jolted into resetting its charge level parameters. Its physically not possible to charge a dead battery of that type to a full charge in 30 seconds. It would melt.
Just for a test I'm gonna have to let the battery run out completely where it won't turn on at all and try it again and see what happens. There's obviously something wierd going on. If I blow it up I'm way over due for a new free phone anyway :wink:
Phonescoop.com shows the the W755 having a 950 mAh Li-ion battery. A computer USB port can deliver up 500 mA of current. Your expected charge time is approximately two hours. As Jay2theRescue suggests, something else happened--like an error in the "battery gauge". Discharging down to self turnoff should recalibrate it on the "zero" level. COtech
So I let discharge completely and plugged it in to the usb and it didn't charge up to full. I left it on for about a minute and it gave a little bit of charge but not like before. So yes most likely when it was saying it was going to die it probably had more charge than indicated.
can one replace the battery in the HTC One ? I am considering a T-Mobile 2 yr contract, but have a sense the battery will become very poor performer in a year. According to T-Mobile, 'effen' phone won't be paid off for 2 years.
