I charge my EVO off of my laptop at work and I have noticed that periodically it will wake up and the little lightning bolt indicating that it is charging disappears. The phone will go back to sleep for about 60 seconds then wake back up and the charging icon will re-appear. Is this normal?
Check your charging cable. Have you dropped your phone while it was plugged in causing it to become unplugged? That happened to mine and now the terminals aren't stiff (yeah yeah that's what she said haha), so it will only charge if the plug is at an angle that causes the terminals to make contact with the upper portion of the slot.
If so, I haven't found any way to resolve that.
If not, can you provide some more details? Will it charge if it's plugged into the wall?

Charges fine when plugged into the wall. Phone have never been dropped. When I plug the USB cable in, I get the option for Charge Only, Disk Drive, etc and choose charge only. It will charge for a long while, then the screen will wake up and the charging icon will be gone, though the icon showing that the phone is connected via USB is still present. The phone will go to sleep that way then wake back up with the charging icon present again. It's very odd.
My phone has started doing something very similar only it is connecting as Disk Drive when I select Charge Only. When it does this, I have to switch it to Disk Drive, then back to Charge Only. Sometimes while its just sitting there charging, it disconnects (like yours is doing) and reconnects to Disk Drive again while Charge Only is selected. I have to repeat the steps above and its an endless cycle.
this could very well be an issue with your laptops USB chip/circuits and/or power profile.
Often times, your computer will try to power down unused components.
Depending on your laptops usb, windows and/or bios may be powering down the usb at which point your phone wakes up, attempts to reconnect (waking your laptops usb up), then starts charging again.
You might try going to your device manager > usb controllers > usb hubs > power management tab > uncheck 'allow computer to turn off this device to save power'.
I agree with it being the power save on the USB ports. You will need to uncheck the "allow computer to turn off this device to save power" for each USB port. Keep in mind on newer desktops and laptops, that there can be eight or more of the selections available for you to uncheck.

I found out that the default setting for doubleTwist media player is to make it automatically set as a disk drive upon usb connection. This setting can be changed.

Here are some issues with a new VZW TP2 that hopefully some of you can help with:
1. I have my phone set to blank the backlight and go into standby while in either battery and non-battery mode, but there's a glitch. I have always kept the device (previously a TMO MDA) plugged into the computer overnight, but this TP2's blacklight stays on as long as the cable is plugged in, regardless of whether it is charging or not. When I power down the computer the charge light goes out but the backlight stays on dim, so in the morning the battery is nearly exhausted. Is there a way to make the phone turn off the backlight while plugged in, even when there's no power to charge the battery?
2. Is there a registry hack to make the volume buttons increase or decrease volume in lower increments? IOW, now when I hit the "+" button it jumps up maybe three bars when I would like it to go one at a time.
3. When in Opera 9.5 and I click on a link within a website it always gives me several choices, one being to open the page in a new tab. Unfortunately when I do that it always says there are no tabs remaining, and does nothing. There are no options for opening the page in the same page so nothing gets loaded, which is very frustrating. How many tabs are there available and why are there never any remaining for use, even just after launching Opera?
for #1. go to all settings--> system -->power
and click on advance tab...you can set seconds when you want to dim the phone n when to turn off for eitrher when your phone is plugged in or not plugged in...i would suggest you using s2u2 to get more backlight options..hope that helps.
2. Not sure how useful this is, but you can fine-tune the volume by sliding on the bars.
3. You can customize the amount of tabs Opera allows by going into opera:config. If you have push internet enabled, this thread may be helpful.

I did that and it's set at 2 and 5 sec. respectively for "On external power." Keep in mind it isn't really on external power at that point, just plugged in, as there's apparently no power coming in (charge light is off on the phone). If I unplug the USB cable the backlight gets brighter but then turns off in 2 min. under internal power.
Oddly, if I connect the phone to a USB cable that's not connected to the computer it will operate normally. But if it's connected to the computer when it has been powered down by XP (Shutdown), i.e. power is not actually cut like if the PSU is switched off, the display will remain dim all night and in the morning the battery will be nearly exhausted. It is as if there is still some signal coming from the computer telling it to stay on, even though I have the phone set to switch the backlight off and go into standby when under both internal and external power. I would like to not have to unplug it every night, as I don't always remember to do it. It's normal position in the house is plugged-in where it can continually sync with Outlook. My old MDA phone had no problem with this and would go into standby whether plugged into the computer or not.
Hey guys, have a friends Galaxy tab 3 (7 inch, SM-T210) which simply won't power on.
Firstly, the device came to me because it was completely dead. He is using an Apple charger (5v 1A) which I believe isn't the right output.
After leaving it plugged into the Apple wall charger for more than a full day, it will power on the display and go into a boot loop (displays Samsung logo for about 10secs then reboots).
It never gets to a point where it shows the battery charging icon.
If I do anything to it (hold power button, power+home+volume up, power+home+volume down) while it is in this reboot loop, it simply dies again and needs the full (more than) a day charge again before powering on the display.
It won't go into recovery or download mode.
The longest I have left it charging thus far is about 2.5 days and still the same problems.
I have tried disconnecting the battery connector multiple times also (left disconnected for up to 5 minutes) - this just causes me to have to start the whole charging process again.
Any ideas? I'm currently leaving it plugged into my PC (rear powered USB port) in the hope that it will charge properly - or at least detect a connection to the PC when it enters the bootloop (maybe try ADB).
@fubofo
I know it is difficult.
A) Regards the Power Adapter.
Listen PC USB port should not be used as a charging station. You always run the chance to burn your PC!
In the other hand PC USB is designed to produce 5V but only 0.5 A.
We should always used the Power adapter that came as original accessory. I own a TAB3 10 wifi. Due to our 10" big screen our OEM adapter is 5V 2A. But in your case 5V 1A is fine. It just charges slower.
B) The most used solution is get in to Download Mode and Install Original Stock software. The other possible solution is to get into Recovery Mode and do a Wipe of Cache and Dalvik and if possible a Factory Reset.
I know you said: "It won't go into recovery or download mode." But there is no other way.
In my cases Tab3 10 Wifi I can not get the battery out. But since you are saying that you can, I will suggest you unplug the battery for a minute. Hoping that when you reconnect it it would not turn on by it self:
1) Turn your PC On.
2) Start Odin3.07 and prepare to install your Original Stock ROM.
3) Connect the USB Cable to PC but NOT to TAB. As you see we only want to be ready to install Stock Rom is everything goes OK.
4) Disconnect the Battery on Tab, (If not possible Press Power for 6-8seconds and release, If it reboots Press Power for 6-8seconds and release. Keep trying until you see it stop doing the loop with Samsung logo. We are trying to ensure is in OFF and that it does not reboot)
Note: Please understand that if you keep pressing [Power] or any other sequence of buttons longer that 8 seconds it just loop once and nothing happens. You need to release the [Power] button.
5) Wait a minute disconnected. (OFF)
6) Reconnect Battery. This is where I an hoping that the Tab will not Turn On by itself! I do not know I never disconnect my battery.
7) Be prepare to Hook the USB cable from PC. Now Press ONLY [Volume Down] and Hook USB cable at the same time. It is been said that when we press Just [Volume Down] from OFF the battery registers are reset and the Battery Icon comes up in your screen!! At least this behavior work in TAB3 10 Wifi. I am not sure in yours.
If you see I am just trying to get away from the "Loop on Reboot" situation. And I believe it your best chance to ensure is in charging state. If you like you can leave it charging for at least 1 hour with the battery logo. If the battery logo goes away and you want to check if it is still there DO NOT USE [Power] BUTTON. use the [Menu] instead. In fact in this mode you can unhook the PC USB cable and Plug your Power Adapter with I believe is twice as effective charging than the PC USB.
Now lets say that when you unplug and reconnect the battery, Tab3 instead Reboot (power on) Then what I will suggest you is to get help from some body else so that you have an extra pair of hands. The Idea is that if it power on by it self ,that you can be only in charge of Pressing Just [Volume Down] while hooking USB cable. The other person will be in charge on reconnecting the battery. I hope you get my point.
Lets continue
8) So now that you have a TAB charged you can ensure that PC is connected to USB cable and Odin is ready.
9) With the battery Icon on the screen, now you can Press [Power]+[Menu]+[Volume Down]. to get in to Download Mode. Note that In my case a TAB3 10 Wifi I do not need to press [Menu], Just Only [Power]+[Volume Down].
10) Follow any Tutorial in the use of Odin for your device. Just be sure NOT to mark "Re-Partition" unless you had received a packages that requires that. If you do not know that means it is NO repartition. Understand that re-partition without having a complete package will Brick your device. Most Odin packages have only the minimum packages so do not required re-partition. You been warned.
I hope this will help you.

@r2d23cpo thanks for this information, though there is a problem. As soon as I unplug it from the wall charger it stops the reboot loop and just does nothing.
Also....why do I need to connect it to PC via USB with Oden if we are not yet going to flash it? Would the wall charger works just as well after I connect the battery? (disconnect battery, wait 1 minute, reconnect battery, Hold Vol Down + connect charger)

I've noticed this with the Apple charger. But only with this particular model. I experienced none with the SM-T217. Other Samsung devices also charge fine with the same charger. The tab wouldn't show the battery icon at all, and the screen kept flashing. I left it plugged in for 1/2 hour and it moved up 1%. I don't believe it's the amp, 'cause the tab charged fine with a 1A Samsung or LG. You should switch to another charger first lest it damages the battery somehow.

This Tab doesn't ever get to the point of showing the charging icon. I currently have the device plugged into USB port of my server as it's powered on 24hrs. I'm happy to leave it in there for a few days to see if it charges better.
My hope is that it will at least get to the boot loop stage, and maybe show up as a connection on my server so I can fastboot it or something.

Not to belabor the point, but mine wouldn't charge at all at 500mA, which is what my regular cell charger outputs. So unless your server delivers more punch than standard USB ports on PCs, looks like you're in for a long and futile wait. Just my guess.
Hey, what's up everyone?
Today I embarked on externalizing the power button on my Nexus 7, That's the easy part.
Now the hard.
What I wanna do is use a time delay or pulse to complete the ground connection to turn the screen on When power is applied. (To what I'm assuming is a time delay relay/pulse relay.)
The part I'm confusing myself on is how to do this. I basically need to know what that thing is.
It would sit between the two ground wires from the tab.
When power is applied to unknown item.
It connects the grounds for a millisecond and then release.
Resulting in screen on.
Any help is appreciated thanks alot
This $1.50 Time Relay Module will do the job, but instead of "externalizing the power button" why not leave your N7 intact and interrupt its power supply?
Settings - Display - Wake on plug​

Thank you very much.
It's a hardwire install. No battery constantly on.
It's in the early stage, so externalizing the power button may not need to be done.
Just getting the research ahead of time.
I'm not really sure if the external powered hub can wake it up, When the screen is off. Or if the USB port will act the same anymore.
The hardwire is connected to the battery board. So the USB port may function as normal. If it does then wake on plug or activity at the USB port wake up is the best outcome.
If functionality is lost at the port a secondary trigger such as
simulated power button
Or wake on Bluetooth activity
Maybe my only routes.
I'm completely open to any ideas and suggestions anyone may have.
"Wake on plug" will work regardless of USB data status or type of power source. I'd cut the [+] wire of a USB cable and splice Time Relay Module there.

The battery board is integrated with a Lipo. Did you remove the Lipo and connect a power supply to ex-Lipo's terminals? If so, what voltage did you apply and is it working reliably?
I attached a picture of the battery board from a mod I did...

We did the exact same mod.
Your bcb looks a little different though.
I too removed the board from the lipo and soldered to the Positive and negative.
I then ran from the ground to the first black wire at the connector and tied in.
I'm using a 12v downstep to 5v 3a to power the nexus.
If the USB port works regardless.
I will not need the relay module. The external powered hub will trigger screen on. (If I'm reading you correctly)
Currently on the bench it has ran flawlessly. Android doesn't seem to mind or notice that it's hardwired or that it's running continuously. Android reads out 100% battery

Yes the hub will trigger screen on but I thought you need an interface to another, controlling device. I suppose you will simply power up the hub to initiate screen on.

That is correct. I was gaining research knowledge, to hopefully get ahead of the game. Incase the port did not act the same after removing the battery. The project comes home tomorrow, Where my real test can begin.
Solved!! If anyone would like to use my way. Don't hesitate to ask.
Hello, so I'm on Android Q and recently having this issues. Tried multiple USB cable but nothing works.
The problem is that when I try to charge-plug USB, it won't automatically charge, instead I need to tap notification-"charging connected via device USB" and select 'thus device' then it starts charging.
The strange things is that when phone off, I could plug the charger and it works. I'm so fed up with this, also the 'charging connected via device usb' seems persistent and annoying
Anyone having this problem? Any suggestion?
Thanks!
You can set default USB activity in developer options. You can control the notification by pressing and holding it and turning notification off.
Thank you, what works for me was cleaning both USB and port with perfume.. thank you tho
Have a P3XL that I'm I was going to load a custom image on. But I can't for the life of me get it to recognize having any form of usb data connection.
When I plug it in, it simply starts charging, no usb notification appears on the phone for adjusting the connection, the computer doesn't make a sound, nothing.
With the very same cable I can plug in a P6 and P3 and they will immediately be detected in the device manager.
I've tried messing with all the USB settings on the phone, turning them off, adjust the default use to File Transfer / etc... (note that none of this is from the usb notification, but the actual usb settings under preferences since it's unable to detect it's even attached!)
I'd had a couple issues with the port only charging sometimes so I bought a replacement charging assembly and installed that assuming that would make all my problems go away and while it definitely fixed the cable so it charges every time, it continues to refuse to be recognized as a device.
Does anyone have any ideas what would cause something like this and what might be wrong to cause it to not be recognized AT ALL (to re-iterate, the computer literally can't detect that a device was attached it's not doing anything, both with old and brand new charging port).
(One other quirk, not sure if it's related...The phone never actually stays off. If you power it down, it will power itself back on just a few seconds later. The power button itself isn't stuck and works perfectly for all the normal functions: tapping/holding etc.. And to be clear, it never shuts itself off randomly or anything like that, it's just if you hold the power button and choose "Power Off" it shuts down and then just reboots 2-3 seconds later)
