"Deep Sleep Battery Saver" .. a great way to save battery. topic

ok... to save even more battery life. Get "Deep Sleep battery saver"

I have a smartphone connected 100% of the time to get all my notifications.
I only use my Note8 for reading and play. There is no reason it needs to be getting notifications of emails, texts, news, social media.. unless I wake it up to use.

after I did the battery disconnect tip. it went from 1.5hrs WAKE time to more than 5 hrs.

but.. even when sleeping.. it would drain about 1-2% battery per hr sleeping.
android and system processes! and media updates.

so I found this app called: "Deep Sleep battery saver".
when the screen is off.. it turns everything off.. all connections.
allows NO updates.
you can set it up .. to wake up for 1 minute every hr.. or 2 hrs.. or 4 hrs. l selected "no waking up".
when the screen comes back on.. it lets the tablet get updates. normally there are none, because I have already taken care of them via the smartphone.

now the Note8 sleeps .. and only uses about 1% every 3 to 4 hrs.
I estimate about 10% per day lost if left alone sleeping.
I think if I left the tablet alone for a week.. it would still have a charge!

Can't save screenshots topic

I just bought an HTC Desire 816 smartphone running KitKat 4.4.2. Before today, I was able to capture screenshots the same way I do so on my Nexus 7 (2013) tablet, by holding down the Power button and the Volume control button. But today, I did that and received a 2-line notification that said:
Couldn't capture scree...
Couldn't save screenshot. Storage ma...

I tried to turn the phone horizontally so that perhaps more of the message would show up, but although I have "auto-rotate" checked and it works on other screens, it doesn't do so here. I have no idea what the problem is nor how to fix it. I'd be most grateful for some help.
