There are numerous things you need to know about charging your phone in order to charge it any faster.
Ampere is unit of current intensity. So higher amperage means more energy in the same time. It does not damage the battery if you charge with lower (or higher) amperage than recommended by the wall adapter, if it's lower it simply charges slower.
USB 2.0 ...
Use a 1/16" drill bit.
Do not put the bit into a drill! Just grip it between your thumb and forefinger.
Press the end lightly into the lint-filled bottom of your headphone jack and spin it clockwise.
Pull the bit gently out; there should be some lint on the tip.
Repeat steps 1-3 until lint is gone.
Clean jack with alcohol and q-tip or whatever you ...
This can be done quickly and easily with a paper clip and scotch tape:
Flatten out the paperclip.
Tightly wrap scotch tape (with the sticky-side out) around the top part of the paperclip.
Carefully insert the sticky end into the headphone jack.
Remind you with the phone itself in your way
Get a small loop, strap, or lanyard which can attach to your phone or otherwise hold it (such as in a small bag). When you enter the stall, hang or clip the phone/bag onto the lock, handle, or knob that you must use to exit.
Whoa, what's that thing on the door handle? Oh yeah, my ...
In case the phone fell into water there is a high risk of short circuits due to the electrical conductivity of water. This does not only cause damage to the parts but can also lead to an overheating of the battery. Over a longer period of time the power supplied from the battery to the circuits causes a reaction resulting in corrosion of the circuits (...
I've done this before simply by taking two ziplock/sandwich bags, one inside the other.
I take both bags, inflate them slightly by blowing into them, seal them tightly, then gently push on them to make sure they seal correctly. I put my phone (in my case my tablet, yes I know) in the first one, suck out as much air as I can get, seal it (very well!), then ...
A battery, once it starts to expand or leak, cannot be safely "restored". A leaking battery will, at the least, corrode the phone and it also may catch fire. If you cannot change the battery yourself, take it to someone who can.
The iPad charger will charge your iPhone faster than the iPhone charger that came with the phone.
The iPad charger puts out 5.1v at 2.1 amps.
The iPhone charger is 5v at 1 amp.
The larger of the two is the iPad charger.
Place the phone somewhere where you have to see it on your way out.
One such place is the door handle of the cubicle / toilet. If there's an old-fashioned handle there, you can carefully lay the phone on top. Now it's impossible to forget your phone.
But not all toilets are build that way. You can:
Lay the phone on top of the toilet paper dispenser (if ...
When traveling, such as on a plane or train, I take my phone with me in case I have to wait for the bathroom. When I go into the bathroom I tuck the phone into my bra strap.
Oh, you're not wearing a bra? Well perhaps you have a shirt pocket. Or you can put it under your arm if you're using both hands for whatever you're doing. Or hold it in one hand and ...
Well, it really depends on what you are wearing. Do you have enough pockets or not? Do you have hidden / hard to reach pockets or not?
If you wear a jacket, store the phone in an inner pocket in the front. If your pant have deep side pockets (the pockets just below the belt), store the phone there.
In such cases, it is best to only carry with you what is ...
Although it would take time, you could prefix all your older contacts with the word "OLD". For example:
First name "OLD Joe"
Last name "Blow"
That way, you would keep the old contacts, but they would all be grouped together alphabetically (because they all start with "OLD") and you wouldn't mix them up with current / active contacts.
To group them ...
Get, or make, a case that covers the buttons. Cardboard or cereal box and duct tape should work well, I would make it thick so that button presses can't make it through. Use colored duct tape if you want a more refined look.
In a pinch you can use socks and a rubber band:
Get four pairs of socks that have been "folded" the way you fold socks. (I'm pretty sure everybody folds socks the same way, but just in case, I'm talking about folding them like this.) Arrange the pairs of socks in a 2x2 square, aligned like cans of beer in a 6-pack. Then pull a rubber band around them so ...
You should use a toothpick, previously buffed with a fine sandpaper. You can use other objects, but with the toothpick you can do it without turning off the phone because it isn't a electrical conductor and you can also sharpen the tip very easily to get better access to the areas. Clean the area in blue...
Pay close attention to the left and ride side of ...
You could use see-through plastic, perhaps bags. Seal with multiple folds. You can test your solution with something similarly shaped but less vulnerable to water. Test in similar conditions, including depth. Once it is working, if you are still concerned, you could make another one, and seal the first one in it.
This may seem obvious, but possibly place it in your FRONT pocket, rather than your rear?
Perhaps the looser pocket in the front will eliminate the pressure on the keys?
Outside of that, the user manual indicates these steps for locking the phone (different from your method described with the back button):
(Screen shot above is from page 91 of this ...
Short-circuit the USB data pins on the phone side, that's what the most powerful chargers do to tell the phone that it can draw the max amount of current without needing any digital negotiation (otherwise it would negotiate with the OS and only get 500mA).
From Wikipedia :
on a dedicated charging port, the D+ and D− pins are shorted with a resistance not ...
Lots of nice answers here, some uninformed answers as well, but I think that most of them miss the actual point.
First thing that needs to be understood is that device called "charger" is nothing more than a dumb power supply. It has no intelligence beyond the SMPS controller, which tries to maintain output voltage as current requirements ...
No. When a battery starts to swell, it is broken and CANNOT not be used anymore. This is a fire waiting to happen - and Lithium fires are very difficult to extinguish.
it only addresses the symptom (gas forming inside the battery), not the underlying cause (battery is defective).
Warnings saying "Do not pierce this battery" are plastered all over ...
In this answer I am going to assume you have a iPhone, smartphone or other gigantic looking phone that would fit into this mechanism. Actually many phones may fit into it, but the designs I saw are mostly for larger phones.

Use a Mini DV case. If you turn the case the wrong way then the phone can sit either sideways ...
A few things I always do to try and preserve my battery life:
I always have the brightness as low as possible while not having to strain my eyes to see the screen - the dimmer the screen, the less power it uses. Also turn off auto brightness as this usually takes more battery than needed.
Turn off WiFi and Bluetooth
Always have these off ...
Make sure that geolocation, bluetooth and wi-fi, 3G are turned off when not needed - they often consume much power
Also, when you don't use or don't need cellular communication, turn it off also (this and above can be turned off by enabling "Airplane mode")
Quit all the apps you are not using
Remove all the apps you don't need or turn off undeleteable ...
Get a thin piece of plastic. Cut it to a normal SIM size and shape and then cut a Micro SIM sized hole that will fit your SIM into it. This should now fit into your normal SIM phone easily - file it down if needed.
If the screen itself is not greasy or visibly soiled then you should just wipe it down with a microfiber cloth. If the cloth is clean the screen will be clean. Clean the cloth though sometimes, I usually clean it with water, but mild soap without buildup should work.
For greasy or just dirty screens:
Slightly damp microfiber cloths will work.
You can ...
They make small brushes for people with braces to get food out. I have a small packet of these in my desk drawer because my phone ports have gotten pocket lint in them more than once. The really expensive ones look like this, but you can get a much cheaper version from your local big box store.
Something else to take into consideration, not really mentioned in any of the other posts, but does affect how fast the phone charges: Even if you had a charger capable of delivering as much current the device was wanting to draw, there is still a limit on charging speed that boils down to how Li-Ion cells charge.
Most cells are happy (And by happy, I mean ...
