Yesterday I started talking about a device picker. One of the things that are critical with a smartphone is some of the common features most phones have. But I wanted to layout those features and break them down a bit as I build out a device calculator.
- Bluetooth – support for BLE and Bluetooth 4 is critical. BLE is Bluetooth low energy and Bluetooth 4 is the newest version of the protocol. Support for both on your phone is critical. 4.0 can interact with any Bluetooth device. So if the devices are running BT 1.0 or BLE, your phone can connect and leverage the device.
- 4g LTE services today. One of the things that makes me nervous is the nature of 4g LTE. It isn’t 5g. But 4g is much better than 3g. I heard a phone company ad the other day that said their unlimited plan was 4g up to 2o gig, and then switched to 3g. 3g is slow. Be aware of what your phone company can do for you!
- 5g if available (today Samsun and Motorola have 5g phones available as does Huiwue and a couple of other companies). 3g is nearly impossible to watch a live TV show on. 4g you can watch live TV, but really can’t do more than just that one thing. 5g you can watch a video, watch live TV, and still be talking on the phone without running out of bandwidth.
- Gorilla Glass screen for your phone reduces your risk of a cracked screen. Cracked screens are the number one repair issue for smartphones and smartwatches today!
- A camera that supports HDR, at least 10-megapixel images
- You will need an installed battery that can support at least 8 hours of talk time and data use. The first smartphones years ago had removable batteries. You could shut your phone down, swap the battery and reboot your phone.
- WiFi built into the phone. If possible, support for WiFi 6. (there are not phones today that support WiFi 6).
- I have integrated a GPS chip that the mapping software on the smartphone can use.
Now the other things are interesting in what people do or do not want. Those will be in the poll questions for today! As we move along the path of making a decision matrix or device picker, there are other things to be considered. There are several other things in the poll questions. The big ones are around the size of the screen.

what are your thoughts on graphene batteries?
good question, my honest opinion right now is I don’t really know anything about them.
that won’t last for long
yes, I added them to my list of things to research.
hopefully graphene and solid state batteries can help us solve some of the power issues we’re facing
i have been reading about graphene batteries, I ended up reaching out to our lab folks in New Jersey, I am talking to them Thursday.
right on. looking forward to learning what you learned
it was really interesting, our lab has prototypes walking around New Jersey right now. The tech is very new, but the batteries don’t get hot at all.
NOICE! don’t need to tell you what an issue heat is. no matter how rich or powerful you are, you can’t break Ohm’s law…
no there are certain things you cannot do. energy the way we use it today produces or generates heat because of the nature of our circuits and connections.
There is an interesting new application of the power flowing through the board continuously allowing greater dissipation of head.
if the entire device becomes heat sync, in theory there would less per square centimeter.
that’s brilliant! graphene will cool it further
The problem currently is that battery life is roughly 3 hours max. They need to get motherboards set up differently. Where the batteries are at both ends of the board. Then the power supply actually charges one battery while plugged in.
sounds like a solid solution
we shall see, right now it requires a new motherboard for the phone or the laptop.
yeah, that’s entirely new architecture…
it really is, we shall see if it happens in the near term. My guess is there is another path that will appear.
size and cost seem to be the driving factors in phone design
The first cell phones were huge.
then everyone wanted tiny.
then everyone started streaming
so big returned!
do you want tiny or do you want to see what you’re doing? currently, you can’t have both…
that is funny as all get out. sad, but true!
on the other hand, they’re impressively thin…
I laughed at the last question, because I do it all the time. Great tips! I’d need some laptop ones too.
That is a great suggestion and I may head down the laptop picker path later
It would be very useful, so looking forward to reading it!
it will be a while I have a number of topics already queued!
My smartphone has some of the features listed. I like the bigger screen.
it is funny when I think about it, my first smartphone 15 years ago, had none of the features!
I like the big screen so I can see it better …. many times it has already dropped, it is very durable
i like a larger screen as well for the same reason!!!!
Our eyes are slowly walking, but it’s good if it’s a big screen
it really helps to have the bigger screen
If the option why not,dear friend
i agree, larger screens are useful. thanks pal!
Thankfully I have not dropped my phone as of yet. I am sure it will happen.
i dropped mine once. Literally walking into my house, the phone rang grabbed it from my pocket, it was spam call, hit end and literally dropped the phone.
cracked the screen in two places.
