BACKside IHO ROM Charging Issue

    I installed the ROM today and have slowly been figuring things out. Really learned a lot today haha. I was wondering if anyone else has had issues with the phone automatically turning on once the charger is plugged in. It's pretty annoying. I turned off the phone and then plugged it in only to see the phone boot up in front of me. Any ideas?

    It's something everyone has grown accustomed to. I have it too.

    It's the same on all gingerbread ROM's but there working on it. For now just turn off the screen.

    That reminds me, my screen also doesn't turn off sometimes. Is that an issue when charging? If you leave the screen on it won't turn off while charging?

    There's a setting to keep the screen on all the time when plugged in.

    settings>>applications>>development>>Stay awak

    Uncheck it. ;)

    Wondering if I'm the only one experiencing this: I flashed backside a few weeks ago and am overall very pleased with it. However, from day one after rooting, the phone won't charge if I plug OEM USB charger cable directly into pc. (Or it will charge VERY slowly.) Same cable plugged into wall charger works great. It's very frustrating because I spend a lot of time in the car and use the USB cable alone plugged into car stereo as my car charger.

    Anyone else have this issue? Any thoughts on how to fix it?

    Thanks

    It's likely you aren't plugged into a powered usb port. Not every port on your pc is powered that's why sometimes you may see an error that something needs to be plugged into a different port. While they all may technically have power not all have enough to properly power or charge a device. Usually the front ports are not powered.

    But of course you know once you start charging you can quickly press the power button and it will black out the screen, it doesn't have to stay illuminated the whole time, the unit will still be on but at least not lit up (like AndyOpie150 said):)

    Ben is right. Unpowered USB ports put out around three to five hundred milliamps at 3.3 or 5 volts, but powered ones put out three times the amperage.

    When I charge mine from the PC, I always turn everything off (airplane mode) and turn off the screen. This always speeds up charging for my OpV.

    same here. It charges up a lot faster.

    turning on airplane mode or booting into recovery will shorten your charging time, so your phone will charge quicker.

    Uh I'm pretty sure if voltage is a constant and if you had a usb port that put out 12volts it would fry any normal USB device since they're all designed for five volts. If you meant 12 watts that would make more sense. 2-3amps at 5 volts.
    The voltage wouldn't be able to change on the fly like that but the amps can. I guess the best way to explain it is you don't draw voltage. You get what you get from the source for voltage as a constant and then you draw amps depending on the power demand usually represented in watts.
    [edit]
    Linkage
    USB = 5v + - 5%=4.75v-5.25v max

    Can you turn the screen off in recovery?

    no, but when you press the power button, it goes to a "stand by" screen, showing just an icon. having the screen on in recovery wont affect your charge time, considering your phone isnt running the android OS in this state, or any other power hungry functions. if you were to have a full charge, and keep your phone on everyday in recovery mode, it would stay on for about a week and a half. (ive tested this, my phone lived for 9 days... in recovery mode) so id say charging your phone in recovery is your best bet at a fast charge.

    Interesting. I always assumed the LCD backlight was more of a power draw.

    it all depends whats being shown on the display, if its just more or less a solid native color such as black, or a small image, it will use less power, but if theres several different images, colors, and other items on display, then it would have to use more power to display the image. also, brightness also plays a part in the display power consumption. the OS and background processes and radios actually takes up the most battery life from my experiences.

    Had a very bad second night with the new baby, and my brain was fried. You are correct, and I should have known better, but insomnia didn't prepare me for the kind of lack of sleep I now get to enjoy.

    Thanks for the tips. I'm pretty sure it's not a powered/unpowered USB issue. I'm using all the same ports I used before flashing that charged the phone just fine, and now aren't charging at all. Juice Defender helps marginally. I'll try airplane mode.

    Then it might be the USB cable.. I noticed that mine wasn't charging at all via USB or a/c outlet. And discovered that the cable is defective and will "go bad~ after so long.

    Most people don't realize that usb cables can go bad. It's like that one pair of headphones with only one working speaker.

    I'm constantly going through them with my car charger. I do get them from the dollar store ;)

    Notice: You can now charge your phone while it is powered off, effective the special 01102012 build of BACKside, and all future builds of IHO. ;)

    Big thanks to Tom Marshall for finally finding a fix for this long standing bug!
