Screwy battery behaviour - have tried batterystats etc

My phone has started to do odd things regarding battery charge level. Have tried full-charge-delete-batterystats more than once, tried restoring older version through CWM and that doesn't seem to fix it.

This pic shows the behaviour quite well:



The phone was shut down (with fast boot enabled) over night, and appeared to be off, but it was draining the battery quite fast and reports that the display was on, despite this not seeming to be the case.
Disabling fast boot cures this, but it never used to be a problem - I've used fast boot for months without this happening. And I quite like the fast power up.

I think put the phone on to charge, and it often seems to charge really slowly. I did a full reboot and left the house. Rebooting caused the charge level to jump up, and then it discharged as I used it quite heavily, before putting it on to charge when I got to work. Other times, when I do a reboot it'll drop 30-40% in charge immediately!

the phone is about 16 months old and maybe the battery is just worn out ... or is there anything else i can try which might fix it?

Hi,

WIPING BATTERY STATS, IS A MYTH

Looks like it might be worth trying a new battery.

That spike in battery % left when you rebooted looks like the standard Sensation battery goofiness... I replaced my battery at about the same age that yours was and its performance had definitely degraded quite badly. It would discharge much faster than when new and charging took longer as well. Replaced it with an Anker 1900 and it's better than ever. Lasts all day and charging is nice and fast.
