[Android Q&A, Help & Troubleshooting] superbonto:
for me, i might have tried most of the steps included in here.

using battery-saving app probably was my biggest mistake after all :D
[Android Q&A, Help & Troubleshooting] rirozizo:
according to this SPREADSHEET, increasing readahead size to 3MB makes both read and write speeds to increase (write by only a little, read by a whole lot). Now this certainly indicates better performance on the sdcard (and the apps installed on it if applicable). Now I don't know if generating readahead cache uses CPU, or just the sdcard itself doing the work, but i'm sure that 3MB won't take that long to generate so this won't affect battery life as it greately affect performance.

TL;DR: make it 3MB, get better performance, no effect on battery life.
[Android Q&A, Help & Troubleshooting] peter-k:
I'll take it that a higher read ahead cache has likely no or a negligible effect on battery.

It is however still good find. I searched the forum up and down, and the opinions I found were differing. This at least has substantiated figures. My cache was set to 128 kb as well, as mentioned in the article. I was not aware that this is done for safety reasons by manufacturers.

[Android Q&A, Help & Troubleshooting] wilberfan:
I almost ordered a 1A charger, until I noticed that was the output of the charger that came with my Galaxy S3. Is a USB port even less than that? And, if so, would it follow that charging your phone via a USB port would be even 'slower' (and, therefore, better)?

Great post, BTW. I've implemented several of your suggestions!
[Android Q&A, Help & Troubleshooting] Tzfardaya:
it's in /system/build.prop

I comment out the stock value by adding a "#" in front of it...

then at the bottom of my build.prop I add

wifi.supplicant_scan_interval=1200

scan time is in seconds... (1200 seconds, 20 minutes. )

edit: sorry, should have mentioned that the stock line is the same as the one I add to the bottom... I just comment out the stock one so I can easily revert it if I need to... I do that with any changes I make to the build.prop... comment out stock, add my custom to the bottom...

usb spec is 500mA (.5A)

which means that's the max that most (not all) usb ports will be able to push... there are some usb ports that are rated to push more power for charging devices
[Android Q&A, Help & Troubleshooting] peter-k:
Here is what I learned.

USB 1 and 2 specs are 500 mA, USB 3 is 900 mA. On a same time data connection charging mA is reduced significantly.

Most phone chargers are specified in between 850 - 1500 mA, and as there is no data connection charging is faster anyway, even if the charger would output the same mA as the USB port.

It is the phone which negotiates the charging mA. Most phones in the market will reduce charging mA as the charge approaches full. Therefore, the benefit of a slow charger is not really significant and charging via USB has no advantage. The best quality charge is done via a dedicated charger and with the phone switched off, so the phones drivers can negotiate what is best without concurrent data connection issues or concurrent users.
[Android Q&A, Help & Troubleshooting] Tzfardaya:
Charging lithium based batteries requires that current drop near the end. The purpose of charging at 1/2C rather than 1C (rather than 1.5C or higher... not that there are many chargers that high) is less heat, less stress to the battery, and better charge "saturation" at the end. The saturation is why you will find that 100% to 99% usage can vary (substantially).

And you're right about the parasitic drain of charging the phone while on, if you're fully charging the phone, absolutely, turn if off... if you're just topping up the charge (20 min on the charger for a bit of extra juice for the night out) then it helps, but isn't absolutely necessary... the parasitic drain can keep the phone from dropping the current properly when the phone is near or at max charge.

[MENTION=847662]admiraljkb[/MENTION], care to double check this for me? I think this is how it was covered before, but you know these batteries better than I do.
[Android Q&A, Help & Troubleshooting] admiraljkb:
Don't have long for a reply. Yeah, you got it right. Charging at lower rates is always better long term, although what constitutes a safe lower rate for long term battery happiness varies by chemistry, which as I noted before isn't given to the common consumer in the phone market. RC Hobbyists get much better data for their batteries. The battery pack and the phone dictate the charge rate from the charger, so typically they'll start slower when the pack is low and ramp up til the last 10% and keep slowing down until its peaked. Fast charging won't kill the cells as fast as a low battery, so to keep it in perspective by all means, "when in doubt - charge it out"

Like UPS's, some mfg's always use the battery to power the phone at all times, and some will use power from the wall while the phone is charging. That could make a difference if trying to do a full charge just from a heat factor if nothing else and getting a false peak on the phones that always go through the battery for power. (not sure which ones are which truthfully, I've noticed differences over the years with phones that required a good, non-shorted battery present at all times regardless of being plugged in). The biggest consumer of juice on the phone though is the screen, so turn that off and you'll get a good charge provided the GPS and wireless radios are NOT using a lot of juice. It would take some in depth testing to properly flesh that out.

Summary - If you're at 80% and going out for the night in 20 minutes - just put it on the 2A (or 3A) charger and let it get as far as it can as quickly as it can. That is far less damaging than flattening the battery pack going empty. If the pack can't take a full 2A or higher, it'll "negotiate" and charge at 1.5A or 1A or whatever.
[Android Q&A, Help & Troubleshooting] KcLKcL:
People right here seem to be against greenify (or perhaps, not against, but "do not recommend" it) because people are using greenify the incorrect way.

So what is actually the proper way to use Greenify? Based on the posts I read here, I read: "Greenify only the apps that you rarely use". Some also said: "Greenify the apps that generates unneeded wakelocks". I'd like to ask it here because if I ask this in the Greenify thread there will be a lot of pro-greenify users that will just say "Greenify works".

Personally, I have 4 messengers on my phone (LINE, BBM, WeChat KakaoTalk), I have em all for various reasons, although I only use LINE and BBM so I left KaTalk & WeChat greenified, because I rarely use them (I seldom use it though). I usually use the Facebook app too, which actually generates wakelocks randomly even if I turn off autorefresh (I knoe the app sucks but it feels way better than using chrome to access facebook.com).

I also greenify apps like Games and Photo editors which I don't actually need for it to be run all the time (they sometimes nags me with notifications I don't want to see too).

So am I using Greenify correctly?

Hi,

does the Wizard have a maximum transfer speed for access to the miniSD card slot?

I'm looking for a miniSD card, and thinking of whether the Wizard can take advantage of the very high speeds of the latest cards. Is it worth giving the extra money to get a very fast card or not?

Is 150x about the fastest available?
[8125, K-JAM, P4300, MDA Vario General] mforce:
AFAIK 80x is the fastest available miniSD

Im using it (1GB 80x)

Maybe we can do some benchmarks? any good software to test memory?
[8125, K-JAM, P4300, MDA Vario General] georgex:

[8125, K-JAM, P4300, MDA Vario General] JNGold:
Don't bother spending extra money for a high speed card. Even going back to the earliest days of PPC's, it's all about the PPC's I/O to the media card. The only real advantages of a high speed card is when using with a digital camera or when using the card in a card reader.

I have a Sandisk 1gb card that runs just fine in my K-JAM. On my 2750, I have a 1GB Lexar sd and 1gb Lexar CF.

I'm glad I found this thread. I've installed some software onto the miniSD card and I noticed they load slower. The worsest problem is now the soft keyboard selection menu takes a full 7 seconds to pull up. I was thinking about buying a faster miniSD to solve this problem, looks like I'll just have to live with it.

this is bull****. Apple hasn't made anything copy-worthy in past one year so now copy windows 8? This stupid thing is simply live tiles (or watevz Micro$oft calls them) combined with the ****ty my magazine app and slapped on top of previous TouchWiz. I can't say i prefer it to old touchWiz

n9005 is better the the n900, but if custom roms is a concern for you, then n9005 is the right one.

in doing daily tasks, there are no noticeable differences except for battery life which i read that it is better on the n9005.

if you can get someone to buy it for you (n9005) and check for hardware issues, it would be great.

i myself had to buy it from outside my country (my cousin bought it and sent it to me) and got it right with no problems from the first time.

i bought the n9005 version because custom roms are a big concern for me (you know, why am i buying an android if i'm not going to mod it?)

For all intents and purposes, you will always want to stick with the Qualcomm Snapdragon version of any phone, including the N900x. The Samsung Exynos SoC may be able to provide you with better battery life and performance (Samsung's approach to controlling both hardware and software of their devices like Apple), but the weak developer support is simply not worth it. And all versions of the Qualcomm model (with the exception of Verizon's) are the same International version with an unlocked bootloader, and therefore can be flashed with any ROM from the Android Development forum.
