Hey all, time for the third Punk Love Designs Identification Contest! This one's a doozy but the prize this time is 1 year of Instructables.com pro service:

A small collection of unusually colored white moss was found growing vigorously on three large rocks at the edge of/ in the stream running alongside War Spur Trail in Pembroke, Virginia. It completely coated the upper surface of three adjacent rocks in a lone, isolated patch with no additional growth in comparable areas. The white coloration may have been a temporary seasonal effect, as each growth showed a slight green tinge at the base. However, the moss appeared vigorous with no apparent ill effects.

The first correct identification commented here with means of identification wins the code for a full year off Instructables Pro Service. The winner will be chosen from available answers on St. Patrick's Day, 3/17/2013.

Good Luck!

For the past two weeks my phone has been getting more and more difficult to keep charged. The initial symptom was slow charging/ finickiness with chargers. This showed on higher amperage chargers that normally worked quickly. Eventually, the phone would charge barely if at all on the best of chargers and slowly lose charge on the others. I also noticed an increasing frequency of connect/ disconnect notifications when plugged into my laptop via USB as well as frequent failure to mount as detachable storage. This left me in a cycle of powering down the device to charge slowly as I slept and scrounging for battery life as I was awake.

What follows is a step by step guide as I diagnosed the issue from easiest to hardest to fix cause. Please be aware that some of these procedures may damage your phone if you make a mistake or simply run into bad luck, so consider carefully whether it is worth your time to repair this on your own versus going through a paid or warrantied repair service.

For me, as my phone is tweaked exactly as I like it and has important documentation on it, it was crucial that I do not lose data as would be expected during a factory motherboard replacement.

there is another problem which was not listed here.

even after doing all these things, if u dont identify any physical damage, what else solution is remind?

i have not found fool proof solution, but i would like share my experience with this

i was getting a connector of 4-5cent from market, and was trying to replace it,

it working 2-3 days later, it again start slow down charging process graually and comes to zero in a week, i go detail here.

u all must be aware, here i am using USB tester, in between charger cable and mobile phone, where it shows current consumption of mobile.

i replaced a connector pin, worked for a week nicely, USB tester was showing max current utilization by cell phone, which is 900ma,

3 days over, started take input only 200ma to 300ma (slow charging started)

to over come this problem, we need press the connector button or pressurize with external material at connector and cable port to make it fast charge, i was using some 50gram solid material keeping on connector pin so USB tester shows 900ma

again 3 days worked, later slow charging, at this time, increase wweight to 100gram. started working nicely

a week over, again slow charging, 200 grams worked 3 days

at last, zero, if u pressure more it shows not charging,

i repeated the same with 3 diffrent connectors which was available in the market

at last, i got original phone mother board. in which processor was dead. i took of that connector and repalced to my phone

working great 15days gone.. good working.. after all suddenly its gone to zero charging....... what it mean? mobile shows charging but it never charge even 1% after 10 hours..

dont this problem of battery, after 1st attempt to over come this problem, i have replaced for original working brand new battery

i really fed up with this kind of problem, i am not getting solution anywhere, what ever i does even service center people does the same for sure.

as warranty got over, they cant give me replacement now.

i am not getting any fool proof solution across internet for this.

i feel, i am the 1st person in the world who suffering such problems and i successfully diagnose it. but not getting solution.

This was a particularly helpful article. It reminded me of some simple things I should be doing to enhance battery performance. It also reminded me to watch out for insidious software wanting to track a person locations. That's why I don't download a lot of games, they seem free, but you pay the price for your enjoyment behind the scenes as they pilfer and sell your info out to others.

this happened to me with my HTC wildfire S. I just replaced the battery and worked as good as new. i tried all of this, removing all the dust of the usb connection, i bought another USB, i removed suspicious apps, and i came to the conclusion of 2 factors: 1. the battery and 2. the internal phone stuff. Luckily, only was the battery, a cheap 7€ solution (I bought a blank brand battery)
good instructable too, i can't edit now :(

this is not how android works. only because apps show up in a task lister doesn't mean they're running. they only got loaded into memory for quick starting times if you actually use them. using android: only full ram is good ram.

also for the chargers: only because the wall wart delivers 2.1A doesn't mean it charges faster than a 1A. The current regulation is done by the charging circuit inside the phone.

Thanks for the article. The article itself notes the presence of runaway processes, and is wary not to take a firm position. Did you see the article linked to under angry birds? If I am losing some performance closing cached processes unwarily and relative to the benefit of closing runaway processes, it is still worthwhile to me for the enhanced privacy aspect of the article:

A 1A charger intended for my phone will certainly charge faster than my 300mA spare charger or for that matter a PC USB port, even if my phone is regulated to 700mA max.
I already downloaded an app killer. I am past warranty so now to take care of bloatware. Thanks a lot.
