Hi, thanks for the reply.
I have tried the soft and hard shutdowns, 1 buzz and 3 buzzes. Tried the battery charging when phone off thing 2 or 3 times now. This issue manifested itself after reformatting due to it throwing a wobbly, this was some 3 weeks ago. Restore done from previous backup too.
To reitterate, once down to 50% (quicker than used to) the battery level declines rapidly, then it seems to jump to 30%, then 20% and by the time the charger is plugged in 10-13% then 3, 1, and off sometimes.
Another longstanding issue, irrelevant to this is 4 text message seem held on a server somewhere as everytime the phone is restarted they come through. This is the tail end of coverage issues in the local area mid last year sometime. How can I clear these too? This issue isn't phone based or related to the battery issue.
I have researched on this and other forums but found nothing decisive on any that has worked. I have checked the phone over a day with no visible apps running, or when the system was interrogated, to cause the sudden decline commensurate with the latest software. I have also turned location services off even though this had, up until recently, not caused an issue.
