Mobile phone
« on: December 24, 2019, 10:34:33 AM »
I'm sure someone on here is smart with mobile phones ??

Have a Samsung J1, only use it for incoming calls and sending odd text. Is on a $70/year plan that entails no data.
Suddenly started using the battery , now instead of lasting a week, 12hrs is normal.
Nothing is enabled....no wifi, bluetooth, flight mode, no live wallpaper etc. Disabled or removed or uninstalled anything I could get my hands on. Put a new battery in....no diff.
Found developer options....no idea what to do there, but I did limit background processes to 4.
Done a factory reset......

If it was a phone that I used, like the wifes S5, I'd just look around for another, but for a work phone that gets used maybe twice a week, I'm hesitant to throw it in the bin yet ..

Is it Samsung using power for something new that I don't know about ??

Don't know about Samsung and this might be a little bit "tin foil hat", but Apple got done a while back for old phones firmware receiving "updates" that effectively killed the battery. This was percieved to be a deliberate move to sway people to get new phones? https://www.dailymail.co.uk/sciencetech/article-7614097/New-Apple-iOS-13-KILLING-batteries-iPhone-owners-battery-life-drains-quickly.html and https://www.macrumors.com/2019/08/01/iphone-throttling-lawsuit/

If Samsung have done something like this, I don't know how to check if they have ??

First link was a bug fixed with a software update in iOS 13.3.

https://support.apple.com/en-us/HT210393

Second link was Apple reducing the operating speed of the phone to extend battery life in older phones with degraded batteries. Because they didn’t  tell anyone they did it there was a big hooha which resulted in Apple offering a battery replacement program as a sign of goodwill. The throttling still exists but can now be turned off if the user wishes.

https://www.wired.com/story/how-to-stop-apple-throttling-iphones/

Neither could reasonably be described as a deliberate policy. I don’t believe any of the major manufacturers would find it advantageous to do so as their public image would be destroyed if actually true.

Do you always run flat before charging - and then let it charge 100%???
I found ONCE I recharged it only 60 odd % and its never been the same since. Read lots on it, something about battery memory or some Shit

Lithium aren't meant to be affected by memory like the old NIMH were.

Where are you keeping it? Same place as before?

Nah, haven't charged it any different to before. Even with the new battery in it, which I have changed back to the original a few times.

Funny that this has just come up. We have two note 4's for quite a few years now, Telstra all the time... Can't fault them, done every thing we needed.
We charge the phones at night and usually by the same time next night the battery is around 82%, depending on how much they are used.

Now suddenly, the phones go down to around 15% and mine went down to 9% and shut down when I tried to do a quick search on the net...

So... Got the same question.... WHY???

Maybe best to use google.  I am sure there will be a techy site with the answers.  I,ve had no issues with my Samsung but I do have it set to power save mode.

This is all very interesting - I had a Motorolla G4 plus that did this exact same thing recently - it was about 3/4 years old and suddenly started going flat and switching itself off at about 40%.
I gave up trying to find out what went wrong and just replaced it.

Same with my HTC M10. Had the battery replaced.
Went well for a while, but now the screen is unresponsive.
Apparently, the way HTC M10's are built makes them a bugger to do, so some replace the screen as the same time.

Have gone back to my old HTC M8, which has had a battery replacement and is going well.

A mate has had the battery replaced in his Samsung, and it's fine.

Used google......many times.....trouble with google, you punch in the details of what you want and it always comes back to a general info site ( that I've already used to reset things ) that doesn't address the criteria that you asked ?

Mine only has ultra power saving mode....black screen with 2 apps showing and can't use most of the settings.

My thing won't ever get 5G, and as far as I know, it hasn't been updated for a while ( no more updates for it ), but you might be right, something from Samsung is the only logical thing to cause it ??

Had an S6 (5yrs old) up until a near a year ago and had no problems with the charge time. Can't complain about a phone if it is years old and doesn't hold charge as long. Have you been in and done the normal maintenance thingy with closing down apps that aren't being used?

As I 1st posted mate, done all that...closed /disabled/uninstalled everything I could get my hands on.
As the phone hasn't got data, it shouldn't have changed from a week ago. It may have happened since the last time it was on wifi ...maybe it got something while it was connected to the web ?

Believe it or not, my wifes S5 is only 10mths old...bought it new.
