#154748 — Things I did wrong when replacing smartphone battery

Things I did wrong when replacing smartphone battery

What do you all think I did wrong? 

1) It didn't hurt things because the phone worked fine for 20 minutes,
but I think it was a mistake to not insist on connecting the main ribbon
cable before I connected the battery cable.  I might have started with
the main cable first, but they both were difficult and I went back and
forth and may have succeeded with the battery before the main one.  This
means the battery was connected while the pins of the main cable were
wandering all over the place in my attempt to connect it.  Even though
the phone was not "on", this is no way to do things.   

The videos I watched, the full-color 16 picture plus text instructions
that came with the battery, and a little other stuff that I read said
nothing about this, but still. (They mainly talked about removing the
old battery and stopped once the new battery was taped in place. 

2) I didn't tighten the screws tightly on the faceplate for the logic
board.  The plate has rubber pads right over the 2 connectors I'm
talking about, plainly to keep them in place.  Even though I felt the
indicative click when I got each connector in place and pressed down,
last night I concluded that the main connector must have come loose
because of maybe stresses from the cable which I had bent back and maybe
twisted a tiny bit??.   And that it would not have come loose if I'd
tightened the screws more, especially the two on either side of the
connector.

And indeed, when I first took off the faceplate, the main connector
stuck to the faceplate, not to its other half. 

However later this morning I unsnapped the two connectors and it took
some measurable force for each one.  No force from a barely bent ribbon
cable would have been enough.  I tend to think I never connected the
main connector right, that the click I felt was misleading.  I brushed
my finger over it but maybe I should have tried harder to move it, and I
would have seen that it was not firmly connected.  OTOH, the cable
stayed in place for at least a couple minutes until I got the faceplate
into position, so maybe it was connected.  

I guess I don't know what I did wrong, but it cost me at least $300, the
trouble of setting up many apps and loading them with the previous
phones data, and the trouble of deciding what I want out of the hundreds
of models for sale. I hate that. 

What do you all think I did wrong?.

I would not dare try to replace a phone battery. I would go to a repair

Well, I came close.  I hope some day to figure out where I made my
mistake. I should have tightened the screws tighter, even though none
were tight when I unscrewed them.   I have an occasional practice of not
tightening screws enough, but this would be the first time it cost me
money. 

There is a guy about 4 miles, 20 minutes, away, but I don't know how
good he is, and didn't ask how much he charges.

I once replaced the battery of a TomTom navigator. I had to open and 
close the thing several times because of mistakes. The cables were too 
thin, a mistake and the cable would be broken beyond repair.

I did manage to do it, but after a month the brand pushed an update that 
bricked my device somehow, it would no longer take map updates.

I also replaced the battery in my Kobo reader. The replacement was hard 
to obtain. The original battery had 3 cables, the replacement had two. I 
had to unsolder a tiny PCB from the original battery and solder it on 
the replacement. It worked for a year, then the battery bulged. So I 
bought a new kobo, which says that we can repair or replace the battery.

Then I managed to connect 3 AAA batteries in an external holder with the 
tiny PCB connected (has a temperature sensor, we think), and managed to 
make the reader work again. Bulky, but it works. I then did a factory 
reset to free one "license slot".

I hate the procedure. Very easy to break something. The guys in shops 
are used to do these things.

I haven't read this yet, so a couple pre-reading comments. 

When they put in non-removeable batteries, iirc they gave the impression
it would enable the phones to be smaller or thinner, probably thinner.
Is that not what they said?   Is it not at least the impression they
tried to leave? 

I spent over an hour fiddling with the phone, two hourss total, and
until I looked at the title of your link just now, it didn't occur to me
that with my model, I donn't think there is any space or size saving
with the permanent battery: 
 
1) there are two flat cables from the bottom to the top of the phone.
One goes under the battery and one goes above it.  That's the one with
the tricky connector. It doesn't follow the same path as the other one
and could be under the battery, with a snall savings in thickness, at
least where the battery is.  But actually there is empty space above the
battery and I think everything now. 

The battery connector is too fussy for most people.  It would have to
revert to the previous style.  They would take some space in the circuit
board, a tiny bit, but the current quick connector takes as much space
on the surface of he PCB. -- I think there is plenty of space in the
battery for it's half of the connections.

3) The case is glued together, that makes it water-something.  I guess
that is very good if a dolphin is returning your phone, and even for
when it falls in the sink, tub, or toilet, or when it gets rained on,
which can happen even to careful people. But I think they could still
glue the back on and give instructions for prying it oopen and regluing.
Or people coudl buy ones that are n more water-whatever than the
previous ones were. 

2027 is not far away, but alas I still can't wait that long.  Plus EU
rules won't spread to the US until all the prior models have been sold. 

So I will be back here is 2033 trying to replace the battery in the next
phone, whatever it is.

If the new phone even lasts 7 years (some do - most don't) you would be
 wiser just to get another new one. As I said earlier, technology moves on
 (quickly). And you will save the hassle you went through with this fiasco
 that's causing your excessive premature aging. I can see your bloodshot
 eyes from here. Scary...  8-O

It doesn't cause aging.  It's the opposite.  I live to fix things.  It's
better than sex and way better than computers. 

Did you see Boys Night Out, https://www.youtube.com/watch?v=zPRhsfT7fU0
1962.   It's about 3 married guys and a single guy who want to rent an
apartment advertised in NYC for nights they are too tired to go home to
Westchester.  Then they get the idea to advertise for a girl to stay
there and be available, if you know what I mean.  By a fluke a beautiful
girl G sees the first ad, doesn't know about the second ad, and wants to
rent the apartment.  The guys think she's okay with their plan, each guy
gets one night per week.  Each guy has his eye on her.  One guy's wife
is always on a diet and she make him diet too, so G cooks for him his
night each week and he's enjoying it too much to pursue her.  Another
wife talks all the time and he never gets to say anything, so she
listens to him and he's happy. 

And the third is too proud to let him repair anything, so he doesnt' get
to.  Girl G breaks things all week so he'll have something to do when he
gets there.   That would be me.  In one scene he's fixed everything and
she's in the other room frantically trying to break something. 

Finally is the single guy who likes her, even though he doesn't want to,
because he is disgusted that she's sleeping with a married man, and 3 no
less.  They don't want to admit what they really do. 

> I can see your bloodshot

Please don't worry too much.   I will post here if my condition worsens.
I had hoped my next phone would have some cool feature I really wanted,
maybe even that I didn't know about. 

But so far, all I see is ASI stuff.  One feature was how to frame my
photograph.  Silly me, I've been doing that well since I got a camerra
at 18. 

I looked forward to eSim, but I would have to give up the SD card to get
it**.  My current SD card has 8GB of data on it.  Mostly photos that I
back up anyhow, but I haven't looked at the whole thing yet. 

**And it was a fluke that I needed esim in the first place.  My brother
and sil were in Peru, and I went to visit my brother and found out
non-citizens can't get a sim in Peru!!!!!  Have you ever heard of that?
(Roaming or whaever didn't work because I don't have band 17, which the
cellular company could have warned me about before I paid $20.  Maybe
they're bluffing and it has nothing to do with band 17.  I don't think
they use Band 17 in Peru anyhow.         They said the charge wasn't
refundable, even though they admitted it didn't work, and after a lot of
complaining, they put it in my "wallet" and I can use it to charge next
year's service.  They should have just refunded it.)  Finally my SIL got
a Peruvian to get me a sim.   This situation won't happen again. 

I thought about wireless charging, but I'm not sure that would save me
anything, since I have a wire at my desk and in the car, and the phones
I looked at haveh't mentioned it anyhow. 

I googled   What feature should I look for in a new phone?   Maybe I
missed something. 

What feature should I be looking for in this new phone?

I keep my photos on Google Drive. That way when I want to bore folks I can
 show them using the Drive app (or browser) on any of my devices. And of
 course I can add a new photo to any one device and all the rest get the
 update. Phone, tablets, even this Chromebook I'm posting with.

Wireless charging is great. I just lay my phone on the pad when needed. No
 screwing around with any wires.
 
>What feature should I be looking for in this new phone?

Dunno. Different strokes. Since I got/still am getting good service out of
 my 7 year old Samsung I'll likely just stay with the brand when the time
 comes...

My Pixel 10 has 7 years of support, but I'm not sure if the battery will
hold that long. I've changed the setting so it's only charged until 80%,
because this is supposed to have a positive effect on the battery and it
should last longer. But if this is really the case?

Long proven. Higher SOCs mean higher chemical and thermal stress for the
battery. The time to charge from 80% to 100% takes as long as from 20%
to 80%. That gives you an indication how stressful these last 20% are.
Higher charging levels also mean more anode plating whereas low levels
below 10% mean cathode plating. Both states mean faster degredation.
Li-NMC-batteries feel most comfortable around 50% SOC (State of Charge).

That works with smartphones, lawn mowers, E-Bikes, BEVs and a lot more
items with rechargeable batteries we use every day.

The experts say so and I expect they're probably right. 

I'm guessing that I've been lucky to get 7 years out of my phone even though
 I've treated the battery poorly.

In the early years I was an overnight charger. My reason was that I wanted
 to start the day at 100% so I wouldn't run out of juice. In recent years my
 phone gets little use and I generally go 2 or more days before dropping to
 80% where I recharge because I suspect the capacity is now poor and I want
 to have as much talking time as possible if a family member calls. Are
 those good reasons to treat a battery poorly? It has worked for me but
 YMMV.

I have also treated my Android tablet toy's batteries poorly but seldom keep
 them very long before giving them to a great-grandkid so can't tell how
 much damage I may have done.

I'm posting with my favorite Android tablet, an Amazon Fire tablet (with
 Google installed) that is now several years old. And I've been overnight
 charging it since the beginning. Guess I'm what you would call a habitual
 battery abuser...

Will I turn on the 80% setting when I get a new phone? Probably not... 8-O

  Well, if you again buy a Samsung, you don't have to set it to 80%.
Instead, you can set it to 85, 90 or 95%! :-)

Tbat was my feeling too.

Yes.  

I've also treated my cars poorly, and none have had engine problems.  I
had one that leaked oil and I could tell when to add some because 5
turns before I got home was a left turn I made quickly, and if the oil
pressure light went on, I knew it was time to add oil.

The courts are tightening up on that, you know.  Part of the "Me 80%"
movement. 

>Will I turn on the 80% setting when I get a new phone? Probably not... 8-O

Question for me too. I don't like when it gets below 40 or 50.  I think
that is very bad for it. 

With the laptop, getting below 30 didn't seem to hurt it but one of
Nirsoft's programs show loss of lie each of the 2 or 3 times I got below
10 I think the number was. 

But I still don't like to go below 40 or 50.

I haven't had a Windows machine for awhile now and have survived. I find
 that my Chromebook does what I need since it runs (on topic) Android apps
 and virtually everything I do has an app or a website.

I'm posting with the Chromebook now. It's 3 years old and has an AUE of
 6-2031 so should last awhile longer. But then maybe not since it's seldom
 left unplugged. And leaving the charger on all the time is good for the
 battery, right? Told you I was equal device battery abuser...

BTW, while it was on, I pressed and held both up and down volume for a
while and it went into some special mode.   A woman's voice was clear as
a bell when she gave instuctions, except for the crucial word or two in
the sentence, which was totally garbled.   Go figure.   I listened at
least twice. 

It told me to double tap the button, but by this time my screen is
totally black most of the time, so I double-tapped in a few places, on
two occasions, but didn't find the right spot.
