Tablet battery question

I also understand the programs that are much more complicated than a book reader would take much more storage, but I think in the case of a bookmark, this would be pretty cheap. Turn off everything you don't need overnight which might consume battery energy - WiFi, Bluetooth, GPS (if it's got one). With those things turned on, it will be frequently looking for updates to Apps, looking for other Bluetooth devices to pair with, and trying to work out where in the world it is. Others have mentioned Airplane mode - which will turn off at least some of those things. If it doesn't turn them *all* off, go into settings and do it manually.

That one seems active. You know while I knew and have a great deal about Ni-Cads, NiMH, Lithium, and lead acid batteries than I care to really know. And I can make Lithium batteries last over 10 years easy. Although the last few years I have realized just making them last as long as you can might be counter productive. So now I am weighing how long vs. how much use you get out of them. For example, making batteries last longer than most people would believe possible isn't very useful if you never actually use the battery for power anyway. And who cares how long it lasts, really? Now your tablet most likely use a Lithium battery. And say the worst case that I have experience with is using one and draining it down to 0% each day. I would expect getting about 6 months out of it before it becomes worthless. Most people are not that hard on them and of course would last much longer. Now you are worried about losing 5% in standby mode. I dunno, per day is my guess. Well you should easily beat that 6 month before it is worthless. Although you should make two to four years easy at that rate. Now I don't know what a replacement battery for yours cost. But if it is like 10 to 20 bucks, well I think it is well worth it, don't you? -- Bill Dell Latitude Slate Tablet 128GB SSD ('12 era) - Thunderbird v24.3.0 Intel Atom Z670 1.5GHz - 2GB RAM - Windows 8 Pro |

However, in phones and tablets, sleep still runs a number of background processes. If power goes away due to battery drain, the contents of RAM are lost. When the device restarts, everything starts for where it was left off, so long as power hadn't been lost. Hibernate is like sleep, but it saves the contents of RAM to a hard drive. As I said, I don;t think that exists in tablets and phones. Anyway, if the battery drains or other loss of power happens, the disk file is used to refresh RAM on restart. My tablet is an Acer 810. There is not a lot of documentation. As far as I know, I can do two things. Just walk away from it and it will go off in a few min or I can press and hold on/off switch for 5 seconds and it goes off. There are three options. Add this: quick press of the power button and it goes into sleep mode. And correct your "walk away" option to read that it goes into sleep mode, not power off mode. -- Gene E. Bloch (Stumbling Bloch) |

You'll have to talk to the developers who make the programs you wish changed. We can't do anything here other than express opinions. Who knows, you might eventually see a few relevant (or not) opinions in this thread :-) I know I am not going to get anything changed here, but other than here, I have no one to talk to about technology. I worked 20 years as an electrician and even with electricians as co workers, I still had very few people to talk to about computers. I am sure that has changed now, but when I retired in 2000 very few electricians were into computers. Did you notice my reply to Paul's remarks? I had misinterpreted your question. My bad. But much of what I said is true. Anyway, there's lots of info happening in this thread... And what the heck, keep up the good fight... -- Gene E. Bloch (Stumbling Bloch) |

If I put it in sleep mode, it will remember the book I am reading and the page I am on, but it uses about 5% of the battery. I've noticed something similar with my Kindle Fire HDX. Putting it into airplane mode cured the problem. I hypothesize that in "sleep" mode it's still actually running. And if it has a wireless connection, it keeps trying to update stuff. I now routinely keep it in airplane mode, except when updating on- device content once a day, or of course when streaming a video. I have seen an option for airplane mode, since I wasn't flying at the time I have always just ignored that option. Maybe I will give that one a shot. Thanks Some Android devices have some automation that will selectively turn off things like GPS and WiFi. You set up a table or something like that to say things like Turn WiFi off between midnight and 8am when device is not moving They are set up to choose criteria and actions by clicking on icons, so it's much easier than writing a program in text mode. -- Gene E.

But I bought two of those 10 years ago and one of the chargers stuck (these was suppose to kick off charge when it was finished), but it stayed on and cooked the battery. The second one never failed and I still use it today to start lots of things (that thing has saved my bacon than more times than I want to recall). Although ten years worth out of one of these batteries are pretty rare. I would guess, one of these days it is going to fail me. I guess I better start looking for a replacement before that happens. ;-) -- Bill Dell Latitude Slate Tablet 128GB SSD ('12 era) - Thunderbird v24.3.0 Intel Atom Z670 1.5GHz - 2GB RAM - Windows 8 Pro |

If I bought a tablet, it would be a very hard choice to have to make between a 7 and a 10. I went large with a laptop, but the big advantage of a tablet is that it is small. Oh man! That brings up all kinds of things. I have 4, 7, 10, and 12 inch tablets. My sig changes by the way depending on the machine I am currently on. And my first laptop was back in '84 with an Epson PX-8. And all the way till 2005, laptops couldn't match a desktop machine IMHO. Then came laptops that could like my Alienware gaming laptops and such. Now I was sold. Got rid of all of my desktops and went all laptops. Then netbook came out in 2007 with the Asus EeePC 700 series (7 inch). I bought a bunch of them for light duty tasks. I was so impressed, I did a test and only used one as my only machine for two months. It did really well as long as you didn't push it very hard. I was nonetheless very impressed. I used the Palm tablets (all pocket tablets) since 2001. I still like them a lot and the newer ones can be MP3 players, play videos, etc. Plus keep notes, appointments, etc. But that is all I knew about tablets until 2012. Bought an Android 4.3 inch v4 and it is ok and all. Kind of small for the web though and can't do a lot of things one does under Windows (I just ordered a 7 inch Android). Also it does MP3 and videos too just as well as the Palms. Palm browser is terrible by the way. If you like text only, it is just bearable. Then I bought two of these Dell Latitude ST 10 inch tablets. They came with Windows 7 Pro. One I upgraded to Windows 8 (this one). Soon I got very curious about earlier Windows tablets. And I purchased two Windows 3.1 tablets and six Windows XP tablets (one I upgraded to Windows 7 and another to Windows 8). So I now know what 3.1 to 8 Windows tablets are like now. -- Bill Dell Latitude Slate Tablet 128GB SSD ('12 era) - Thunderbird v24.3.0 Intel Atom Z670 1.5GHz - 2GB RAM - Windows 8 Pro |

Sleep just stops the device from running while using power to keep memory intact. However, in phones and tablets, sleep still runs a number of background processes. If power goes away due to battery drain, the contents of RAM are lost. When the device restarts, everything starts for where it was left off, so long as power hadn't been lost. Hibernate is like sleep, but it saves the contents of RAM to a hard drive. As I said, I don;t think that exists in tablets and phones. Anyway, if the battery drains or other loss of power happens, the disk file is used to refresh RAM on restart. My tablet is an Acer 810. There is not a lot of documentation. As far as I know, I can do two things. Just walk away from it and it will go off in a few min or I can press and hold on/off switch for 5 seconds and it goes off. There are three options. Add this: quick press of the power button and it goes into sleep mode. And correct your "walk away" option to read that it goes into sleep mode, not power off mode. Thanks DO you know whether your Iconia supports two quick presses in succession on the power button ? To go into Deep Sleep. Paul No I did not. Thank you. |
