I know, maybe stupid q., but i dont know if I should just do cycles by completle discharge battery until the phone shut down and then charge...

And charge completely to 100% without interuption or there can be some??

And isnt it bad for lithium battery to completely suck it??

How many cysles??

Should I do some calibration on 100%???

Etc.

Thanks...

PS. It is said in kernel discusions (Saiyh kernel) that it have several cycles for battery to be with better life, or something..

I've always been told we really don't need to do this on our phones. Maybe in an extreme case?
[AT&T Samsung Galaxy S II SGH-I777] axis01:
Entropy preaches this.

LiIon batteries don't like to be discharged to zero. Typically, don't let it drain it past 25-30% before you recharge. The "battery cycles" are referring to your typical usage and recharging habits. Basically a more technical way of saying, give it some time.
[AT&T Samsung Galaxy S II SGH-I777] karate104:
Is there a similar upper limit guideline? Like, are we not supposed to charge to 100% overnight? I've heard for all manner of phones/laptops that it doesn't matter that much if you leave it charging overnight because at 100%, it's smart enough to not draw any more power than to keep it from discharging. But then I've also heard that shortens your overall battery lifetime. So what's the rule of thumb on this for our phone?

I need to watch my drain more closely, I think I let it drop past 25% fairly often if I'm not at home, and even sometimes when I am DX
[AT&T Samsung Galaxy S II SGH-I777] votinh:
LiIon batttery:

+ never let it completely discharged to Zero. 20% is usually a start charging point.

+ not a good idea to let it completely charged to 100% then leave it there for long time.
[AT&T Samsung Galaxy S II SGH-I777] godefroi:
Note that "overnight" does NOT qualify as a "long time". This advice is referring to things like your video camera, which, after using it, you might store for weeks or months. Charge it to 40%, and put it away. If it's away for a REALLY long time, pull it out and recharge it to 40%, because you don't want self-discharge to kill the cells.
[AT&T Samsung Galaxy S II SGH-I777] mattdm:
Doesn't the 20% rule seem rather arbitrary? If what I think I know about batteries is correct, % capacity as reported by the phone isn't based on the "actual" capacity of the battery. When the phone reports 0% charge, the battery is still supplying about 3500mV, and about 4200mV at 100%. So really, discharging to "0%" means discharging to about 83% of theoretical capacity. The 3500mV limit is determined by the minimum operating voltage of the phone's components, not really by the battery.
[AT&T Samsung Galaxy S II SGH-I777] Phalanx7621:
So if I'm reading this right...the reported battery % is actually higher than what we're shown....because it has some kind of "reserve" for when its almost completely dead? Or no.
[AT&T Samsung Galaxy S II SGH-I777] MotoMudder77:
kill your phone and take a voltmeter to it. but yes, that should be the fact, I know little about Lion batteries, but electrical power is same in general.

whatever is required to run the machine must be met or it wont run. so its smarter to have our % adjusted as such. rather than having the phone shutdown at 40% battery because of lack of voltage.
[AT&T Samsung Galaxy S II SGH-I777] yahoowizard:
Meh, in a year or two, I feel the batteries might start to deplete, but let's be honest, we'll have new phones by then =D
[AT&T Samsung Galaxy S II SGH-I777] Shammyh:
Current != Voltage.

Aka, the battery could still have 3.5 volts but no amps. And hence cannot power the phone. Volts will slightly decrease as the battery is discharged, but without any amps left it doesn't really do much good as a power source for anything...

Google "volts vs amps" or "voltage vs current" for more info.
[AT&T Samsung Galaxy S II SGH-I777] mattdm:
I'm an engineer; I understand the relationship between voltage and current.

Current is not determined by the battery; it's determined by how much current the phone draws from the battery. I'm just saying that the current demands of the electronic components of our phone are too much to operate from a power source that's only pushing 3.5V. Hence, that's the artificial "0%" power level of the battery.

You're digging too deep into what I said though...my point is just that I don't think it's bad for the battery to let the phone discharge to 0%.
[AT&T Samsung Galaxy S II SGH-I777] Felix2402:
Dang. After reading this I feel like I totally raped my battery. One question, a little off topic maybe... Even though our phones calibrate the battery themselves, is it important to charge the phone to 100% before installing new roms. I've been doing this ever since I had my fascinate. Is this still necessary?
[AT&T Samsung Galaxy S II SGH-I777] tuto3324:
I got 2 questions.. i use 2 batteries in my phone, the one thats come with it (1650 mAh) and a replacement that i bought of 1800 mAh.. So when im using the phone i let the other battery charging and then i change them when one is discharged.. it is bad for the phone to constantly use batteries with different mAh? and the other one is that if it appropiate to do battery cycle when im using the 2 batteries.
[AT&T Samsung Galaxy S II SGH-I777] Felix2402:
Thought I would get an answer but that's what I get for not searching thoroughly.

Apparently we don't need to charge to 100% before flashing a rom. Although it is not recommended to flash roms on low battery (below 50%) to prevent problems,rom related I'm guessing. This is just from what I read. Please correct me if I'm wrong.
[AT&T Samsung Galaxy S II SGH-I777] Nick281051:
You're right, it was necessary on the Captivate but not here
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
You don't. Ever, with one exception:

If you have a battery that has been sitting completely unused in storage for a VERY long time (many months, possibly longer), it may not perform well initially. Just 1-2 discharge/charge cycles of any sort will get rid of the passivation layer.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
It is not necessary on the Captivate either. Whoever told you that was completely unaware as to how that device's fuel gauge chipset worked.

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] shawnthecableguy:
Hi guys,

I normally try and work this stuff out for myself (as you can tell by my join date and my post count) but this has me stumped..

I was attempting to change ICS rome and somewhere in the process something went wrong...

After many unsuccessful attempts of flashing, stock ICS & GB, Abyss.. I checked the partions for errors and found the actual size of p-10 was different than the reported size by 1kb.

So, tried the e2fsck fix- it reported that it had corrected some errors.. I tried flashing again and agin- no success.

I then deleted the partitions, recreated them and reformatted in CWM. ADB reports no errors on any partition. When I try to load an ICS rom, it installs then hangs when it gets to the screen where you select the language.

I can successfully install a GB rom, but after a couple of minutes I start getting errors- then the affected app closes.

Any ideas?

Thanks

When you go back to GB via Odin, you HAVE to reboot into recovery first and do a factory reset wipe. I know the other person mentioned it, I just wanted to make sure you understood.

Hello everybody........Great website by the way very helpful all the time.If anybody can please help me it will truly be appreciated...Thanks in advance!Long story short.....My GF was taking a video with her LG P970 and then it stopped because the SD had just reached its limit so the camera just forced closed.After that I noticed the phone became laggy(More than it already is btw)then there was a message in the notifications bar "Removed SD card"although it was still in the phone.The phone then started to freeze so I took out the battery and turned it on again but still the phone kept saying "Removed SD card"and when I tried the camera it would never open just a black screen would pop up and nothing......Just force close....(Good grief)..........So heres what ive tried.1.Factory Data Reset from privacy menu in settings.2.Tried other SD cards (5 other ones by the way).3.LG support mobile tool updating.4.Smartflash program to reset the phone to stock.5.Tried a bunch of different DRIVERS to see if it could find the SD on the computer.6.Ive also tried downloading a camera app from market but they all just FC's.ETC,ETC,ETC.So there you have it after all that still no SD CARD found and the camera app still crashing.I would give up and say that its a HARDWARE problem but Ive had something like this happen before with my Nexus One and somebody flashed some camera thing on it and it worked again.Her P970 is not rooted or anything like that btw.Thanks again :confused::confused::confused::confused::confused:

Thank you very much for the response.......Ive tried both of the links but unfortunantly theyre dead links.......Also I forgot to mention that I am new to Root/Flash techniques so not so good.Using the Smartflash tool has been the only thing ive ever used............But I have a question?Do you think ROOTING and maybe putting a different Rom may solve the problem?Maybe CyanogenMod idk?Thanks in advance......And would you have a good link to view "ROOTING FOR DUMMIES"because I wouldnt know the first thing to do with a ROM.Thanks
[LG Optimus Black] Pacos1:
Link updated!

I definitely don’t recommend to play with rooted roms with devices with hardware problems.

What I have linked is a tool to bring the device to stock conditions and so bring it to the service without trouble. You have said you have used Smartflashtool, this may have flashed some unofficial stuff which erase your guarantee claims.

Be aware that you do this things on your own risk!

nothing to do?

someone really solved this problem? Is frustrating 'cause i can not use my card at all, my camera don't work and some days it freezes 20 times, I must to take out the battery and it freezes again after 2 minutes..

Hi, i´m just new on Android. The HTC One X is my first Smartphone and i want to install the Android Revolution HD 6.0 rom. I know this: First i need unlocked via Htcdev and install SuperSU. That is clear for me.

But in the instruction for ARHD 6.0 says, that i need to flash the boot.img of the rom first and then install the rom. In the tutorial are 3 files: ARHD 6.0 - ARHD super wipe and flash_boot_6.0.0. In the last find a READ ME: I need to run the install-boot-windows.bat and then install the ARHD in Recovery.

That is where i´m confused.

Must i the boot.img of the ARHD One X 6.0.0 flash or run the intall-boot-windows.bat. Or both?

I know, are many tutorials but i have this problem and it´s my first time with Android and ROMS.

BTW i´ve install the last OTA (1.29.401.11), i live in germany and my phone ist unbranded. There is a problem with this. Must i have the 1.28.401.9?

Follow these steps:

1. Unlock via HTC Dev.

2. Install Clockwork Recovery

3. Boot in to the Bootloader and Flash boot.img in ARHD thread via Fastboot USB.

5. Flash Superwipe Script in ARHD thread

6. Flash ARHD 6.0.0

7. Exit Recovery and Restart.

Thanks man, i will try it.

One more question. The file Flash_boot.6.0.0. What is it? Do i need it?
[HTC One X] dr9722:
Yes you do need it and it needs to be flashed prior to flashing the rom. Simply open the zip file once its downloaded, put your phone into fastboot-usb and run the install-windows.bat file. The boot.img file is then automatically flashed.
[HTC One X] floepie:
The boot.img is packaged in the zip/rar file, which contains a batch file that somewhat automates the boot flash. So, the boot.img and the flash boot 6.0 are one and the same step.
[HTC One X] fredfb:
Yea you need it.

But you don't flash it using CWR, instead you unzip on your pc and run the script for your OS. In windows its a bat file that flashes the boot.img to your phone
