Hey, Today i've been doing some tests with a lead and acid battery at 5,2V and 4,5 A/H . I plugged my Xperia E1 in the battery using the usb charger connected to the battery, and the phone, well, the charging led became green, 5 secons later red and the phone shut down. now, the phone is "dead" and the charging led is allways red... has it any solution? is the phone dead forever?
Solved! Go to Solution.

the voltage was only 0,2 v more, and the amps, i said Ah, not A what means that the battery can give 4,5 Amps maximum, but that is auto-regulated by the device.

a microfuse? that seems less bad as i thought it could be...

Sorry but the phone doesn't regulate amps or volts - Thats the chargers job and a USB 2 port on a Pc only has a 5v 1amp output so the phone would have no issues charging from that so as I said in my 1st post too many amps and as your phone doesn't have quick charge then I'm not surprised by the outcome

Many years ago when I was 16 I became a qualified Mechanical and Electrical engineer so I must emphasize that the battery you were using is a DC and you tried to charge a phone which requires AC - At no point have you mentioned you used an inverter to convert the power types so although you keep saying it's not Amps it's A/H then without an inverter to regulate this then the A/H or amps output was far to high
