Power issue/damage

I have a Tmo G2 that's been functioning great until recently. I've had it in an Otterbox Commuter case since purchase in January. It was dropped twice I believe. Recently, though, any moderate tap to the back lower bit of the device, below the battery door, turns it off. Does anyone know what sort of issue this might be? Is it as simple as a broken trace/solder joint on the battery leads to the board? An unseated chip? Thoughts are appreciated before I tear this baby apart (no warranty on it, and I'm not too squeamish about working inside). Let me know. Thanks!

Update: I've isolated the problem to the lower right corner of the phone, looking at it from the back. Popping the battery cover off and pushing on the lower right corner causes it to power off. Has anyone experienced anything with loose battery terminals?

Do you have an extended battery? Could be the metal on the battery making contact with and shorting out the sdcard holder slot. Put a piece of tape between the two.

No I don't have an extended battery. Everything's stock, plus the case. It could be a shorting issue, I guess. I'll try isolating any metal and see.

Nexus 4 Back Glass Replacement Help.

I know this is a silly question. But I cracked the back of my nexus 4 from a 1 foot drop, (out of my pocket while I was crouched down spray painting in the garage). Just before I did this I was starting to have battery issues, basically under 20% the phone doesn't charge unless its off. Even on the stock charger, it just loses power and then dies and turns off again. Its frustrating now because I lost my warranty due to cracking it.
So My question is, if I go on (Ebay) and buy that glass, will I be able to do a clean enough install that they will take it as warranty and not notice? I don't want to buy the whole back assembly because its rather expensive with all the antennas to keep everything working.
I'd like to hear your opinions, or from people who have replaced just the glass before. Thanks.

You can do it, you just have to take off the entire back cover, peel off the NFC and charging coils, and gently pry out the glass. Look up the thread where someone put in a second battery (total of 4200 mah) in his Nexus. He has removed the (shattered) back glass off of his phone, and replaced it with a plastic housing for the 2nd battery. You could see how he got the glass off without damaging the cover. The hardest part I would think would be getting the glass to stick on while keeping the stock look. I don't know what kind of adhesive LG uses to glue on the glass, but ideally you would want to use the same kind.

[Q] Nexus 4 Battery Major Issues After not being used for 6 months

I've had my nexus 4 in sotrage not being used for 6 months.
Have been now using over the last 3 days and it charges to 100% then less than a hour later it dies instantly when its under 80%
Is there a method to"reset" the battery so it doesn't do this?

You are probably going to need to replace the battery. Just be careful when you do it; watch a couple of disassembly videos and make sure you use proper tools to disassemble. You will need a guitar pick or a plastic case opening tool, a Torx T5 screwdriver, a Phillips #00 screwdriver and something (solvent?) to help you remove the adhesive that holds the battery to the front display/case. If you pry to hard on the battery without doing something to remove the adhesive you can break your screen. The battery itself can be ordered for less than $30. Good luck!

nexus 4 battery screws?

I was checking my battery and tried to remove it and stripped the head on one of battery screws
I am sure I can get it out, but would like to have a replacement for it.
Found several on E-Bay but they just show a many screws and I do not know if
the battery screws are included
Thanks

I would like to know where to get the little battery screws and also the back cover screws.

It's been a while, but does anyone know where to get them on the cheap?
I need both the battery screws and the back cover ones.

I didn't get any on the end, I don't have the phone anymore though.

Have you tried Ebay?

Notes from my Honor 8 Battery Replacement

While it is fresh in my mind.
1) The seam for the back is not along the surface, it is along the edge. The silver part and the glass is where you want to attack. It is going to be hot, wear gloves.
2) Don't use metal tweezers around the battery connector as it is always hot. I accidentally shorted the old battery and was afraid I'd also hit the motherboard but apparently did not.
3) The battery is glued in SOLID even though it appears to be a tight spot. The thing is, there are flat cables underneath (see photo) and the screen so you have to be careful. I have read not to use heat on it but I think you almost have to use a little. There is the frame between the battery and the screen, but too much leverage could easily damage the screen. I did not glue my new battery down. We will see.
4) If the thing turned on (or you turned it on) without the fingerprint sensor connected, you will need a reboot to find the fingerprint sensor. At first, I thought I had not seated the cable but then it dawned on me to reboot before I took the cable bracket and cable back off. That fixed it.
I managed to chip the midframe a little in one spot. Not bad and invisible in the case. Not very noticeable without the case. In fact, I didn't glue the back down yet because my case holds it all together with no issues and I thought I'd take a day or two to make sure nothing is going to pop loose in there.

Thanks for the write up.
Did you end up reusing the old battery door adhesive or go with a new one?
Wasn't sure from your post.
Also how's the new battery holding up?

After about a week with it in the case, the old adhesive was stuck on good so I left it alone. The new battery is holding up well. Phone is no longer my daily driver, though, but the battery is great.

Replaced my battery last night. End up reusing my old adhesive which worked out well. When it was still hot/soft, I took a flat head screwdriver and lightly drew the adhesive back flat on the surface as much as I could before beginning the full teardown.
That did the trick for me.
As for the battery itself, you're right... the battery is in there with some very strong adhesive. Had to actually use my heat gun to soften the adhesive and free it. For me, it wasn't coming out any other way and this part took the longest.
Didn't heat the battery directly as I didn't want to burn it so I heated the area from the screen side....be very careful as you do this as the screen can get burned as well. (Don't ask me how I know)
Overall the new battery is working very well and the phone feels like it did day 1 again. Can't wait to see the SOT time later this evening
Edit see attached...almost 5 hours again with 25% left with normal use and auto brightness on Nougat. Can easily see 6 hours at this rate! Very impressed

Damn this looks more complicated then changing it on an iPhone

YMMV but personally I can vouch that its one of the more time consuming and challenging repairs vs usual iPhone jobs. They use some type of space age adhesive that quite difficult to remove. Most of the repair is trying to gently remove the back glass, battery and screen. If you can quickly get those out without damaging the components, the rest of the repair is simple.

Are there replacement backs? My battery lasts maybe an hour of SoT at this point. I've tried factory resetting it. I'm tempted to get a new phone (because I'd like security updates), but the H8 is still fast enough to use. Mostly not knowing what I'm doing I figure breaking the back is fairly likely.
