Hi Xavier. Thanks for your lucid response. Questions understood, and the reason for them. 1) Phone - IS the same as a couple of years ago. 2) Battery - IS the same as a couple of years ago. "Aha! There's the problem"; I hear you cry. And I understand your logic, (where you're coming from). I am an engineer and am cognisant of the problems of aging batteries, diminished capacity, reduced current delivery, and such. However, in defence of the battery in this instance, I am reasonably confident that it is still giving respectable delivery. Daily drain under normal circumstances is so far not unduly reduced since new.
Clearly you are technically aware so I'll refer back to parts of my original post:- a) "Just normal daily use receiving mail, texts, making the odd phone call, *running Osmand as a map*, the consumption is OK". To which I could add listening to radio for several hours per evening, and other usage. b) " Battery lasts all day, and more." This phone model does have an unusually high capacity battery. It can still easily do 24 hrs between charges, but is generally charged overnight. I could send a screenprint of the battery status at the end of a typical day (with no Osmand usage) for comparison. I could send another including Osmand usage (ie tracking location whilst moving, but WITHOUT NAVIGATION INSTRUCTIONS) Purpose of the above - To confirm long running time (slow battery drain) in the two foregoing conditions. I believe I have already satisfied myself of this but do not have any recorded evidence to hand. Hence my question "Power consumption - Has it crept up?" Am I really the first user to comment? Thanks in advance.
