The warning about the speaker module being “very delicate and prone to breaking" is no joke! I took the speaker out of the phone I was repairing with no issue. When I attempted to take the speaker out of the phone I was salvaging parts from, the front “screen" part of the speaker stayed stuck to the phone as I pulled the module out. It fell apart, accordion style; the innards falling out in stages. I'm guessing I did not shove the point of the tweezer quite far enough in while I was prying it out.

My contact wires got bent the first time I took a phone apart. I am pretty sure I bent them when I was prying the phone open (not while I was putting back together). Now I'm extra careful prying the phone open on the volume button side and it hasn't happened again.

After replacing the battery, I charged my phone to 100% on an original Motorola charger (powered off, slow charge, overnight). I ran the battery all the way down (it lasted all day with heavy use), then charged it overnight again (powered off, original charger). After that, I tried to charge it with my fast charger and it will not recognize it at all. I also noticed when plugging it into the original charger, while powered on, it says it's charging by USB - that's trickle charging. I'm going to try wiping the cache to see if that helps.

I have a Droid Turbo that I fast-charged for years without compromising the battery (I'm using it as a backup now and the battery is still fine).

The screws in my phone were both sizes. I had to use the T3 and T4. A few of the screws would not take either bit (I had to use a dremel tool to strip it slightly so the T4 would fit it). Luckily, I had some replacements.

My phone had odd, terrible screws. Some of them were half way between a T3 and T4

I was so scared of puncturing and bending the battery. I slid a guitar pick under one edge (long side) and then wiggled a grocery store loyalty card under the battery. I took my time and it came out intact with no bending.

Good idea. I always do that.

Definitely pull it off from the bottom corner of the battery. That work so much better. It came off mostly intact and I stuck it to a piece of wax paper till I needed it.
