Usually, when I apply a screen protector on a phone, it typically last the duration of my phone, this appears to be true for my son as well.

However, for both my wife and daughter, I seemed to have to apply a new screen protector several times a year. First the sides starts separating often a week after they are applied. Often cracks starts to develop. My wife is particularly careful with her phone, and drop it a lot less than me so it's not because they dropped it too much.

My current hypothesis is that this is due to some sort of skincare product that they use that may causing the adhesive to fail. The other possibility is that they stored their phone in their purse instead of their pocket like I typically do. I would expect being stored in my pocket would be more stressful?

Anyone in the fixit community have a clue?

Hi everyone,

unfortunately, the battery connector on my ASUS motherboard broke off directly from the board.

The connector didn’t just come loose — it actually broke off the PCB. I’m wondering whether this can still be repaired, for example by soldering the connector back on.

Does anyone have experience with this kind of repair?

• Is there generally a chance that the battery connector can be soldered back on?
• Is it still repairable if some of the solder pads on the motherboard are damaged or ripped off?
• Would it be worth taking it to a repair shop that does microsoldering / motherboard repairs?

I can also upload photos of the damaged area and the broken connector if that helps with assessing it.

Thanks in advance for any advice!

I want to share my experience with replacement batteries because over the last few days I have been testing NOHON, DEJI, and original batteries on older Samsung phones, and I discovered something quite important.

On my Galaxy S6 edge, I installed a brand-new NOHON battery and, even after several charge cycles, AccuBattery was basically stuck at around 91% health.

On my Galaxy S8+, the situation looked even worse. A new NOHON battery was showing only around 86% capacity after several cycles.

At first, I naturally assumed that the batteries simply had less real capacity than advertised.

However, the problem turned out to be more complicated.

Older Samsung phones can keep battery-related data from the previous battery, including cycle count, discharge data, fuel-gauge/ASOC values, and other information used by the system to estimate battery condition.

Simply replacing the physical battery does not necessarily reset all of this data properly.

Because of that, the phone may continue estimating the new battery using old battery/fuel-gauge information, and an app such as AccuBattery can then calculate capacity based on incorrect system data.

On the Galaxy S6 edge and S8+, a proper battery/fuel-gauge reset is not as simple as doing a factory reset or clearing AccuBattery data. On these older devices, gaining the necessary access may require procedures involving Odin, TWRP/root, etc., which in my case also means accepting Knox 0x1.

After properly resetting the relevant battery data, the results changed dramatically:

Galaxy S6 edge + NOHON: around 96% capacity

Galaxy S8+ + NOHON: around 99% capacity

So the exact same batteries that I initially thought had only 86–91% of their rated capacity showed almost their full advertised capacity after the old battery/fuel-gauge data was reset.

On newer Samsung devices, things are much easier.

Samsung provides the Self Repair Assistant / Repair Assistant, which can reset the relevant battery cycle information after a battery replacement. On some devices and software versions, methods involving Shizuku + SMT Shell can also be useful, although compatibility depends on the exact model and Android/One UI version.

So my advice to anyone replacing a battery in an older Samsung phone is:

Do not immediately assume that a new battery is bad just because AccuBattery shows 80–90% health.

If the phone has many years of use and a large number of cycles from the previous battery, first check whether the battery/fuel-gauge data has actually been reset correctly.

Also, a normal factory reset of the phone is not necessarily the same thing as a proper battery statistics/fuel-gauge reset.

Of course, I am not saying that every 80–90% AccuBattery result is caused by calibration. Some replacement batteries really do have lower-than-advertised capacity. But my experience shows that on older Samsung phones, you should not judge a new battery only by AccuBattery before checking the phone's battery/fuel-gauge data.

I actually made this mistake myself and initially blamed the NOHON seller because I thought the batteries were under capacity. After much more testing and a proper reset, it turned out that the batteries were actually very good.

Hopefully this helps someone avoid buying a second or third battery unnecessarily.

I have a Microsoft surface 7 with a broken screen & requires the power to be wall plugged in all times. Can I remove the screen and use it as a “CPU” of sorts?

I have a M1 Macbook Pro 2020 and a M1 Macbook Air 2020. Logic board of the Air works bur cosmetically its unusable, the Pro is perfect cosmetically but the logic board is dead(other parts work just fine). My question is can I swap the motherboard of the Air one directly to the Pro and have it working? Its going to be a headless setup and im only gonna use it to run a server so its going to be used in clamshell. Do you guys think its possible?

It's a rural electrical grid with 20 year old house n wiring.

Recently moved there and my Macbook pro started giving my finger shock or made my fingers numb. Time passed my fingers got worse, lost flesh. After 1 year mac book pro died.

Same happened to 1 more old laptop dell latitude.

Two mobile phones even with plastic chesis - same

I thought earthing is missing- fixed it - still same

I thought I would charge them while switched off and use on battery. Same.

I thought may be higher voltage - used a stabilizer.

Voltage usually arround 210 to 245 shows on stabiliser .

I got broke amid all losses, Recently I got a new Idea pad slim 3. 2 days and the cycle of hands numbing has started while typing or touching.

So stabilizer failed too.

I suspect the Lenovo adapter, Belkin adapter of mac are damaged as well and they will kill more electronics if used? If you know , can u confirm ?

I called and electrician and the guy either did not care or gas lighted me. He came with a old school tester as a tool. It's rural India. I feel trapped. I hate this.

If you know a full proof cost effective solution, please share.

does anyone know how i can fix it? or do i have to take it to a repair shop

As mentioned on the caption, the guided access touch is turned on. I accidentally turned it on and I cant even unlock my phone because the touch aren't even responding.
I already did some ts:
- force or hard reset multiple times and waited for half a day to try again but still not working (quickly releasing the volume up and down then tapping and holding the power button)
- charged iphone to 100% and depleted it until shuts down then charged it again to 100 (still not working)
- i paid a technician to replace the screen and inspect if there is water damage (there's none)
- i can't delete / erase all data because i cant unlock the phone. i can't go into a recovery mode because i can't tap the screen.
- i also tried to access my iphone using pc. i connected my iphone to my pc using the apple device app but in order for me to delete data on my iphone using the pc, i have to allow the permission on my phone which i can't do because i can't even unlock the phone... i really believe the guided access touch is turned on because i airdy charged it to 100% but after a few hours, it is down again and it heats if there's battery so after it completely turns off because of lowbattery, i didn't charge it so it wont be on
