Even though you already drained the battery and recharged it, I would recommend doing it once more (except let the phone die), just to recalibrate the battery. After that, check out what is eating up your battery in the settings. Try playing with the different radios (BT, WiFi) and seeing what effect each one has. If all of these don't work, try getting a ...

I own an Android smartphone with a lithium-ion battery. I want its installed rechargeable battery to remain useful for a decade, if possible. Completely improbable. Even in optimal storage conditions, a rechargeable Li-ion battery will not last 5 years let alone 10. And optimal storage conditions means 40% charge at 0°C, not room temperature. Secondary ...

The actual capacity of a battery decreases as the battery ages through an irreversible fading process. This capacity loss occurs both with active use, correlated with charging cycles, and with inactivity through self-discharge. The device may even come with substandard batteries. However, the amount of loss is linear with time and accelerates with ...

I am having the same problem, with no red light when charging a nexus 4. I changed the usb cable and it charged. The problem came back however. I just noticed that if I held down the buttons while inserting the cable, the red light came back on. After a while, it started blinking, and charged fully. I use my nexus4 for development, so it is on for days ...

Buy an Ampere-meter for USB-port like this LED USB Voltage & Current Detector Power Supply Amp Tester for Mobile Power ETDS Then try different charger/cable combinations until you find one that works for you. Keep in mind that the ampere-meter may influence charging behaviour.

Might be your charger, in conjunction with whatever is going on with your phone while it is charging. Check the fine-print on your charger for the output current value (measured in amperes "A" or milliamps "mA"). My Samsung charger which came with my S5 charges my phone in little over an hour. The charger supplies 2A (amperes) of current. Another charger I ...

By using a 2A Samsung charger and USB doctor and Samsung Chargring Current Lite app, I found that the MAX current reported by both USB doctor and Samsung Charging Current Lite App is 1A(1000 mA).

I had a similar problem a few years ago with my old HTC EVO 3D which was also running cyanogenmod at this time. I tried flashing different roms and kernels but the problem was persistent. Because my battery was empty as yours is at the moment, I charged it by cutting a USB Cable and applying "+" and "-" to the battery directly. It looked really bad to be ...

Not possible as for an unrooted device. I had to open the phone to identify the port.

It was happening to me to 'till yesterday. My battery was draining really quick and I went to "notifications administrator" and turn off almost every notification. The fact is that battery is not drainin' so fast. Only 15% since yesterday, so for me it worked!

By looking at your screenshot I think you should wait a few days to see if your new device settles down a bit on battery usage. Why do I say that? Even though your battery is draining fast when your screen is off, there are not many wakelocks. Give your phone a little bit off time to settle down ( syncing data between all accounts etc.) and it should be ...
