Ok , i been plugging my phone to my usb hub for the last 2 days and took up to 10 hours to recharge my phone until I plugged my phone directly to my motherboard.
I'm now charging at a rate of 2-3% /5 mins
I'm actually at 20% , 2:38AM

New to the TB - I have a question about the battery. No it's not about how fast it drains. My concern is charging time. My previous phone was an iPhone 3g. It would charge in about three hours. 1 hour would net you about 50% charge.
My TB seems to take FOREVER to charge. As of writing this post - it has taken one hour to charge from 55% to 65%. This is with the screen, data, gps, wireless and bluetooth off. the only thing on is the voice portion. Anything more would be airplane mode.
At this rate it would take 10 hours to charge this phone. On the iPhone, you would get 10 hours usage and 3 hours charge. On the TB you get about 3 hours usage and ten hour charge time.
Does this seem right?
That's not right if you're using the AC charger which came with it. Are you?
If you're charging over USB, it's going to take a long time. Charges via the A/C Adapter usually take about 3 hours, same as your I-phone. The first charge I recommend leaving it on for 4-5 hours to make sure battery is fully charged.
BTW, there's really no reason to turn off all of the features just to charge your phone. I leave all of those features on and still charge in < 3 hours.
well I have been charging by pc usb port on both mac and pc.
Tonight I plugged into ac adapter. It took 1 hour to go from 85% to 99%. 50% faster, but still excessive. It's a ~6 hour charge time instead of 10 hours.
I would love a 3 hour charge time.

going from 0 to 75 % will be faster than 75 to 100.. charging isnt a linear thing. as you reach the the end of the charging cycle you are trying to move charge across the battery with a 5V potential but fighting the potential now built into the battery...

Depending on the level you start at, somewhere around 85% is where charging changes over from constant current to constant voltage. If you charge with the AC adapter, you'll find it takes ~2 hours to go from 0 to 85, and another hour to go from 85 to 100.

My Streak is only 3 days old and I am thrilled with it but .....
Last night I shut it off and put it on the wall charger as usual at bedtime. It had about 80% charge left and had been working fine all day.
When I got up this morning and tried to turn the phone on, it said "0% Charge" and shut itself off. I had it on my cigarette lighter/usb charger in the car on the way to work (1 hour) and it still said 0% charge. I have had it on charge from the usb on my desktop computer in the office for 1-1/2 hours now and it says 20% charge.
When the phone is shut off, what the heck could discharge the battery completely in 6 hours????? Could the charger be bad and drawing current from the battery? (Shouldn't happen - poor design if it did!)
If it is REALLY sensitive to input voltage, maybe the USB charger in my car isn't high enough to charge the Dell? (I have seen some usb devices that actually want 5.1 to 5.2 volts to charge.)
Anyway, it is slowly coming up but I need to figure out what killed it over night. Has anybody else had this happen????

Did you fully shut-down your streak, or just turn-off the screen? There is circuitry that stops the battery from charging once a full charge is reached, as over charging will ruin the battery. So the phone should be on while charging. Another thought... Will it even charge if it's not on?
P.S. the thread title does leave some room for jokes
Yes, the phone will charge while it is powered off.
Your car charger may not have the power needed. I have seen a few posts about the car chargers.
Something does not seem right. While on the wall charger it should have been at 100 percent.
Also, my phone will charge fully in 2 hours on the wall charger, not sure of the time on USB.

[email protected] dc can charge a hungry streak to full power in 2 hour.
It'll take about 3 H if you are using [email protected]

Getting stranger!
After two incidents where the phone SHOULD have charged over night but was dead or nearly dead in the morning, I plan to switch to a USB charger that I KNOW is good but .....
When I tried to power up the Streak this morning (after being shut off last night and left on the charger over night) it was TOTALLY dead - didn't even light up again when I plugged it back into the charger! - so I stuffed it in my pocket until I got to work.
I popped the battery out and measured it - no-load voltage showed 4.0 Volts. When I put the battery back in, the Streak booted fine and showed 100% charge! (It was not battery contacts - I cleaned them a few days ago after the no-charge incident).
It appears that there may be something in battery-backed memory that got out of whack and removing/replacing the battery cleared the error state allowing the Streak to boot. This could tie in with the apparent charging problem?
Any ideas?
Hey XDA community,
Two days ago, I flashed my S2 to Cyanogenmod 12.1 and as always, the battery dropped to below the 15 %, so I put it to recharge. After some downloading and updating and installing, I put the phone to recharge again while it was on 4%, and I left it all night (for 7 hours) and when I woke up, I found it only at 22 % !!!
I turned it off and went to work on my laptop and put it to recharge on USB cable, the problem is that instead of recharging and going up, it showed that it was recharging but going down from 22 to 19 to 12 !! After some turning on and off and going to recovery mode, the battery died and I left it turned off for recharge, but it stayed on 0% for more than an hour !! It won't budge anymore.
I turned it on and off so it will completely discharge and recharge it with USB cable and an AC USB adapter and it actually started recharging. I took it off at 64%, flashed back to Jellybeans (JellySnap) thinking that the CM 12's battery issue isn't fixed yet, but even on Jellybean, I'm still struggling with the battery problem ! This is what happens now :
_ Recharging while turned on : It would show that it is recharging for 7~15 seconds, then it will ask to connect charger even though it's connected.
_ Recharging while turned off : The loading bar is moving but after 7~10 seconds, it would stop and the phone would either turn on by itself and start the same problem up there OR keep on rebooting on the Empty battery with the loading circle screen.
I also left it to recharge all night (6 hours) and when I woke up this morning, I found it stopped on 20%
I left it to recharge now (turned off), and so far so good, the loading bar hasn't stopped, but I need to know what is the cause of this issue. Is it software/firmware problem ? The battery ? The micro USB port ?
I have had my g3 for about 2 months now and the last 2 days i realise that it barely charges. I usually leave my phone overnight and its always at 100% in the morning but 2 days ago i plugged it in at about 15% at 12am and by 9am it was only at 54%. I thought it was really strange but didnt think much of it i took out the battery put it back in and put it to charge again. In 3 hours it was only at 70%. I realised there was something wrong but i couldnt figure out what was causing the problem so i let the battery emptey and tried charging again. Again the charging was extremley slow. So i took my friends charger and it was full in an hour or so. This was a relif knowing it wasent my phone that was the problem. So i decided to see what the problem was i took his usb cable (which was also original) and plugged it into my charger and it charged quickly but when i plug in my cable its slow w even on his charger. Does anyone know whats going on?
I've never had good charging in this phone. Sometimes its super fast other times it barely charges if the screen is on. I have the damn thing plugged in and just saw it drop a percent. Charging port is to blame IMO. Its a piece of ****.
Had the same issue with my 4 months old LG G3. Different cables didn't make a change, original LG Charger was the problem - when charging on external battery it was always fast, when charging on my genuine Nvidia Shield charger it was always fast. So i decided to buy a different charger (i-tec USB Power Charger 2 Port) and also new cable (Wsken X-Cable) and no longer any problems...
This phone worked fine for a month and then suddenly one day the tubo charging stopped working.
Usually, when we connect the phone to the charger it shows Turbo charger connected, but it's showing charging only now and taking too much time to charge. From 15 to 34% in 2 hours almost. Battery temperature is 31°C and have restarted it many times. Phone is not charging in switched off state. Any help.
