I haven't tried it. -- Cheers, Ralph. -- Next meeting: Online, Jitsi, Tuesday, 2023-06-06 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
Re: [Dorset] Android permanently Awake.
My Phone is Android 9 Motorola. Under Apps/Special App Access I can find a Battery optimisation, which for a lot of Apps, says 'battery optimisation not available' Going to try it on my phone for awhile Peter. Bah - all the android differences.

The battery chart's detail has ‘Media’ as one of the top two users, but the percentage of all those that are listed is well under 50%. I suspect Media though because clicking it shows it is Awake for 100% of the time and used CPU for about 50% of it. Perhaps that's a dual-core thing. What app is this battery chart?

She may have nothing ‘running’ in terms of apps she can swipe closed or ‘Clear all’. But Android does much unseen and without any means of controlling it. > Dear S-in-L who is an Electrical Engineer, suggests getting a better > charger with more oomph. I am not aware speed of charging has much effect on speed of discharge. If the battery charge is reported as being 100% then it doesn't matter how it got there as far as I know. I've charged this phone slowly using a 5 V, 550 mA plug and USB data cable. And quickly with the ‘TurboCharger’ plug-and-cable-in-one which shipped with the phone. I choose on convenience. It makes no difference to my tests. This is a software issue here. As I said, by ‘Force stop’, etc., on all apps, I could get the discharge to level out for a few hours. It's ‘Keep awake’ which is killing the battery. And that's caused by software telling Android it wants the phone kept awake. -- Cheers, Ralph. -- Next meeting: Online, Jitsi, Tuesday, 2023-06-06 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
Re: [Dorset] Android permanently Awake.
Hi Hugh, > Slow charging speeds are also very much caused by the cable type. But the issue is fast discharging, not slow charging. :-) -- Cheers, Ralph. -- Next meeting: Online, Jitsi, Tuesday, 2023-06-06 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
