I have a mate 7 that is about 3 years old now.
The battery ran out at >5%, and never turned back on again.
Even when plugging into charger, nothing happens, no light, no vibrate, nothing, complete stillness.
No matter what buttons I press the phone is completely off.
I opened the phone and checked the battery and measured some test points.
The 5V is present when I plug in the usb charger, and the battery measured at 3.6V.
What is strange to me is that even when I plug in the charger, the battery voltage doesnt increase (charger).
Any suggestions? Any ideas? Any other tests I can do?
Edit: Should the phone turn on without the battery and only with charger?

Does anyone have experience charging the battery?
I was using the phone it went dry, as in
I did get the warning that i only have 10% left / 5 % left and then i kept using it until it pop up a message saying
"To prevent damage to the phone, it will now turn off"
and off it goes
but when i plug it back to the USB cable, it got no sign of charging, no light, or indication of any kind.
if i try to turn on the phone, only the Soft buttons lid up, but it doesn't do anything.
Also when i had it plugged directly into the wall, it was not shown as charging, when the phone is ON and running the OS.
but now that the phone is completely OFF, when i plug in the USB charger directly to the wall then it shows the Battery Bar @ 5% for only a brief moment and then goes back off

Yes, it always happens if you squeeze all the juice out of the battery. Be patient and let the cable connect. After a few mins, the touch buttons will light up. then after a few more minutes, the screen will light-up and show you the charging icon. By that time it reached 15%, you can already press the power button to boot the phone.

The same exact thing seems to be happeneing to me. Did you figure out how to turn it on? I charged it overnight and nothing has changed except that the battery status shows a full charge. I still can't turn it on. After I take it off the charger and replug it in, it shows 5% again. Thanks.
the problem with mine was just a cable issue, found another cable, and it worked fine.
it didn't like the after market chargers
Most of the time this is not cable problem... If your battery is down and you put in PC USB - it will light after... you will wait a lot. If you put it in AC charger it will light after while.
PC USB is 500mA, AC charger is 600mA or more.
thanks for all the advice. I did get it to charge and boot. I left the battery out of the phone overnight then plugged in the original charger and the soft keys lit up and aftr 25 minutes I was able to turn it on all the way. Quite a relief.
Today my Triumph seemed to be draining the battery faster than normal, though I was also making a lot more calls than normal. I have a cable plugged into my PC at work which I plugged into my phone but the driver install window didn't pop up like it normally does and my PC's network connection got very slow. I unplugged it and my PC connection was fine again. I left my phone unplugged for the most part after that though I did plug it in once or twice. I don't think it was ever truly recognized by my PC at work today (it has worked before) though I'm not certain.
When I was about to go home I noticed my phone was off. I knew it was low on battery so I assumed that it had turned off due to low battery. It couldn't have been off any more than 30-60 minutes. I didn't think it should have turned off already for low battery yet though.
I plugged it into my car charger and my phone refused to turn on. About 20 minutes later i unplugged my phone and the red charging light was still on. I had to pull the battery. I then turned on my phone and it was working, but low on battery.
About 45 minutes later I drove home with my phone plugged in, but I didn't check to see if the charging light was on. The phone was still on. When I got home I tried plugging in the phone and I noticed that it was not charging. It still isn't. I have tried the following:
Restarting phone
Plug in while it is turned off (charge light comes on but not charging animation, must pull battery for light to go off. phone will not start while plugged in or charge light is on)
Try plugging into computer rather than wall
Try car charger
Swap battery to stock battery (I use an Anker battery rather than the stock. I haven't used my stock battery for a few weeks to a month. It should have been fully charged but only had less than 50%) and try everything again with same results
Right now I have my Anker battery in which was nearly dead (below 10%) plugged into the wall with it off hoping it will charge. My phone is mostly stock other than I rooted it using the b_randon14's method, installed b_randon14's tweak mod, and flashed in the Sprint PRL using a method from howard forums with the 60681 version. I had links but had to remove them due to not previously posting on this forum.
I noticed the usb cable is not solid in the prot on my phone, but it never was and doesn't seem any different. For example I can move the cable back and forth a little bit while plugged in. It remains plugged in when I do this and while the phone is off it knows it is plugged in obviously. Any ideas?
Ok... I left it plugged in while off for an hour then it started working... very odd. Nevermind then I guess, lol.
Saw this thread, was going to suggest that. Your issue seems to be one that happens across all sorts of devices that have rechargeable batteries, even Android phones (and especially $&!t MP3 players that you'll find at K-Mart). I once made the mistake of buying a $30 MP3 player that refused to turn on once its battery dropped to a certain level. Twice. From K-Mart, of course.
Thank goodness for returns.
I am still having issues and it is really frustrating. Sometimes it will charge when on, some times it won't. The only thing I think MIGHT be common between when it does and doesn't work is how much battery is left. I think it might work more often when the battery is closer to a full charge. What I often do is plug in the phone, shut it off, it will charge but charging animation isn't there and I cannot turn it on until the charging animation shows up. I think it only shows up when the phone is fully charge or close to it (I've only ever seen it when it is fully charged).
Unfortunately I don't have a lot of concrete information on this as i haven't had much time to troubleshoot and verify any of my suspicions. I do know that USB Debugging has nothing to do with it and clearing my battery statistics didn't have any affect either. This issue is very frustrating and I believe are all software based, not hardware.
Any ideas or pointers?
Out of curiosity, have tried a different USB cable? I know that you talked about switching chargers, and I couldn't tell if this was just the base unit and you plugged the same cable in or, if it was a completely different charger and cable.
I have a wall charger with a usb cable at my office, a wall charger with a (different) usb cable at my house, and a car charger with its own non detachable usb cable. All have the same issue.
I recently picked up an unknown condition motog 4g. Won't boot. I figure it had self-discharged into oblivion. Cells came up at 2.16v, but I didn't trust it, got a fresh battery off Amazon. New battery shows no love.
When plugged in, I get no screen but the notification light goes white.
Things I've tried:
Charging for 24H on 2A charger
VOL DOWN + PWR 2min
freezing it
unplugging the screen and letting it charge
holding power for 10+ minutes while off
holding power for 10+ minutes while on charger
So, I've tried everything. Still don't know if it's a corrupted bootloader (possibly?) or if something else is wrong.
Any suggestions?
I've got a friend with the same situation pretty much. We have not frozen it yet, who can tell me how to do that?
He has had it since new, it is bone stock, and nothing will bring the battery above 0%. I'm looking for some last ditch things to try before we pull the back off and unplug the screen to charge, or replace battery.
Any help would be appreciated.
Have you tried charging it on a low amperage charger? I know other variants have had charging issues which were solved by charging on low amp chargers, such as a computer's USB port. Those generally put out about 500mA or less unless they're powered.

Figured I'd update here:
I bought a new battery and put it on a 5W charger for 24 hours. Came back to life.
Hello,
With an Xperia SP phone, i have something very strange, the battery is empty, i plug the charger, see charge animation with low level, one minute later or less i see 100%, i power on the phone, still 100%, unplug the charger, the phone immediately power off, i plug again the charger, again, empty to 100% in one minute or less.
Thank to take time to read me.
Been having some issue with my Xperia 5 II with wall outlets. Phone does not charge with wall outlet and portable battery. Tried different wires but does not charge. I did notice that when I plug the phone to the wall outlet the phone detects it cause I feel it vibrate but just doesn't charge. However it does charge with the same wires to a computer.
Anyone having this issue or have any solutions?
My phone was dead one morning and when I plugged it in I got a vibration but the LED light that indicates charging did not light. I tried everything and as last resort I went to the manual. It said that if you drain the battery when you start charging it gives no visible clue, none, until it hits around 15%. That was true. I plugged it in and read a book and eventually the red LED came on and the phone charged and all has been well.

before this happen when i charge my phone either below or above 15% it shows the charging icon on the battery and the red LED. And like I mention plug in to charge on the computer under 15% i see the LED on and charge icon on the battery. Nonetheless i will try your method and try plugging it in under 15% to see if it charges.
Tried charging the phone at 0% and also inbetween 0% and 15% still not charging. The only way for it charge now is on a fast charger sony usb c cable.
