My HTC One XL is a few months old. Yesterday it was down to about 15% charge so I put it on the charger (wall socket). The charger was at work and came with the HTC Desire but that shouldn't make any difference.
It got to 88% by the end of the work day so I took it off charge and went home.
I made a call OK, then put the phone on the home charger (the one that came with the HTC One XL).
About an hour later I received a phone call on the home phone. This is unusual as I don't give the number out. It only rings when the mobile phone diverts to it. I use this as my message bank. I checked the phone and it wouldn't power up. I left it alone out of frustration as I had other things to do last night.
I put the phone onto charge via a USB cable into a PC this morning and after 20 minutes was able to power it up. The battery said I was at 2%.
My question is how can a phone go from 88% to 2% in under an hour (without playing Angry Birds :P)?
A bit more information, the phone has been running very slow for a few weeks. Switching between home screens can take a few seconds, the soft keyboard takes about 10 seconds to load, etc. It is intermittent but usually lasts for a couple hours. I can't find any apps that would be causing this. Any ideas on what could be causing this?
Should I return it for a service or replacement under warranty? I see this as a final step when all else has failed. I don't think I'm there yet.
The phone is stock and un-rooted.
