So, I got a new phone a bit ago. A better smart phone -- a Galaxy S3. I know, I'm two models behind. But our plan is a "buy your own phone" plan, and I have a set budget. And the S3 is a great phone.
I wanted it mainly for the superior camera. The screen size doesn't hurt given my 50 year old eyes are suffering from 50-year-old disease.
At any rate, the original battery just wasn't cutting it. It'd typically drop 10% in the first hour, and that's with no GPS and no Bluetooth. I like a phone with a good 24 hours time on it before I think it needs recharging (this one would give me about 12 or 14 before it was getting down close to half empty ... sometimes emptier.)
I want to be able to use it -- use the features -- and not really worry about being a battery miser and calculate when and where I could get my next charge. So I started hunting around for a better battery. They make them... but not MUCH better... unless you want to go bigger.
And you can. There are double capacity batteries. And there are triple+ capacity batteries.
Turns out the way ZeroLemon does the triple capacity battery means the phone won't be thicker than with a double-capacity, and so I went with that one. It's thick. The phone was originally about 1/4" thick. With this battery it's just about 5/8" thick. So it's a bit of a brick. Almost 3 times as thick and probably about three times as heavy -- I even changed the startup sound to the intro-flute riff to Jethro Tull's "Thick As A Brick".
So What Would McGyver Do???? (WWMD?)
I went to Westlake's Hardware and bought a packet of brass shim stock. There were varying thicknesses. One was almost foil ... so I picked the next thicker. I marked the side of the battery to show the position of the two contacts it covered, and I cut two strips of that shim stock and used double-sided tape to tape it to the battery. Two parallel strips.
Before I taped them and cut them to size, I rolled up one end of each so that they would stick down into the holes where the contacts were for Qi charging. Ended up cutting about a 1/8" strip of foam to attach to the bottom of the battery to push them down into the contact wells.
I then filed down the contacts on the Qi receiver card to about 1/32 of an inch to keep it from bulging the silicon back too much, taped it down with some packing tape, and put the back on.
Wireless charging works like a charm.
I used the phone rather more than I typically do after a full charge ... as a test, and after 64 hours it was down to 50%. I don't like getting lower than say about 25% ... and with a lesser capacity battery, probably more like 40%.
I charged it fully last night, and this morning I turned both bluetooth and GPS on and I've used it to play music in the car and otherwise used the phone as I normally would.
12 hours later it's at 89%.
This is what I want.
I want to be able to use the darned phone however I feel like using it and not have the battery so low I worry about conserving it so I can make or receive a phone call if I need to.
So I'll charge it up every night, and just use it. That's the ticket.
