It wouldn't change how long the battery really lasts but if the phone shuts down at 0% you won't be able to use all the energy stored in your battery and if the phone stops charging at 100% although in reality the battery isn't fully charged you'll never get the real 100%.

But I don't believe that is actually happening.

If I look at the charging process of my Macbook, calibration works in a different way.

I have to let it run completely out of juice until it shuts off and then charge it until the battery is full. The battery stats file will then get renewed with those two absolute points. No manual erasing of the stats file is necessary.

I haven't tried it but I believe Android works the same way.

So instead of erasing the stats file it would be worth a try to just give your phone one complete cycle. Let it run until it shuts itself off, no matter what the percentage reading is saying and charge it again. After that's been done, check again how long the battery will hold or better, how accurate the reading is.

I've never calibrated my battery in all the time I've been using ACA and my percentage reading has never differed more than maybe 4-5% from the reading I get in winmo at any given time, when I switch systems.

[HD2 Android SD Development] shamez23:
Maybe he's using a Mac and assuming the same thing I do.

The Macbook is the only notebook I know of that has a precise description in its handbook concerning the matter of battery calibration.

Apple is well known for being easy to use, not troubling their users with things the system can do on its own. Still they thought it necessary to address something like that.

With all the "knowledge" about batteries and how they should be treated that can be found on the internet I always kept to that description, believing that the engineers that build the macbook should know what they are talking about.

Doing so served me well in the past and until someone similarly "trustworthy" comes up with a believable explanation to do it differently, I'll keep away from erasing battery stats and things like that.

Although Apple thinks they invented the wheel, sueing everyone else to proof it, we all know that they do as much "steeling" as every other company. I'm quite sure they weren't the ones that came up with this calibration strategy. They are only using it. And if I'm not completely mistaken so does everyone else that is producing similar electronic devices.

I find it hard to believe that the engineers at htc and other companies would expect the average user to root their phone, get a file explorer, dig deep into the system to find that file and erase it, to make the battery work.

Here at xda we might think that for most users doing something like that is an easy exercise but we are only a small percentage of all users.

However almost everyone sooner or later will get into a situation where their phones will run out of juice and of course they will fully charge it again as soon as they get the chance, unwittingly calibrating their battery at the same time.

At least that would be a perfect explanation why the internet isn't completely drowning in battery issue questions by the millions of owners of billions of battery driven computers of all kinds.

Re: battery calibration...

I charge my battery in a charger many times. So, I restart my system close to 100%.

I've gotten better life from using the 2x battery app. I also have juice defender and that seems to be helping out too. It's all so relative because none of us know exactly how others are using their phones so it's hard to compare.

[HD2 Android SD Development] Jerome.Ramos:
RE: LCD Density Change

Hello...try this...

1)Download Root Explorer v2.16

2)After downloading Root Explorer, go to

/system/build.prop. Look for ro.sf.lcd_density (the default is 160) and modify the number and save and reboot.

I use 240
[HD2 Android SD Development] Nemesis2k9:
I thought 240 was the default?

Anyway I love the higher screen density but its just some apps don't scale well and it kinda takes away from the otherwise polished look and feel of the ROM. For example the default app wither is not always shown on screen properly, the dial pad is smaller and that annoying Orange line through the selection highlights. So until all of that is polished out I wanna stick with stock screen density.

[HD2 Android SD Development] shamez23:
Higher number means bigger icons. 240 is the dpi on stock ROMs.

You could try something in between 167 and 240 if you like the smaler size.

I've read several times that users found 200 to be a good compromise.

60ma battery drainage in standby after call

I am experiencing high bettery drainage while the device is in standby, the current is usually around 5-6ma but then it goes up to 60ma, it seems to happen after I make/receive a call and then stays like that until I reboot the device; this didn't happen with an older version I was using previously (a May/June one but don't know the exact version).

Does anybody knows if it is possible to addres this issue? :confused:

[HD2 Android SD Development] iivuch:
Current goes from 6mA to 56mA and back

I have been using ACA since its early days. Latest builds especially are great - very stable and nice. The only thing are these current jumps. I found that if I do not use mobile internet, with average usage, occasional WiFi and GPS, some text message etc, the phone will go without recharging easily for 4 days. However - the moment I turn the mobile internet on, the whole hell breaks loose. Battery consumption goes through the roof. But OK, I knew that mob.internet is hungry. So I keep it on for a little while to check e-mail, sync various stuff and then turn it off. Unfortunately current does not go back to 6mA, but stays on 53-56mA. In these cases when I have not noticed - the battery quickly drains completely. If I manage to see that this happens, through series of random WiFi on/off, Airplane on/off, mob. internet on/off .. all comes back to 6mA if I am lucky, but it makes me a bit nervous as to why this happens.

Any clues?

Regards

Ivan
[HD2 Android SD Development] iamlegend2:
Thanks

It changed to 3072 after restart, but in read_ahead_kb file, still shows 2048 :confused::confused:

any idea ?
[HD2 Android SD Development] evo1rs:
Not sure if that means anything, that file is deep in system files, if its changed in init.d then it should have worked.

Maybe warren or cope will answer this if they get time!
[HD2 Android SD Development] p107r0:
just in case - after reboot make sure that the changed file contains 3072,

then set its exec permissions

EDIT: checked on mine, nothing works, not copying the script to system.ext2 on PC (img mounted with gizmo), commenting the "if - fi" lines around line 28, so the command is executed each time also does not work
[HD2 Android SD Development] mcklane1:
Thanks Ivan, so you managed to get the current back to 6ma without rebooting?

Anyway the easiest way to monitor current usage is to use current widget as it can record easily the current when the screen is off.

Could the cause of the issue been the fact that the phone doesn't go in standby but only turns the screen off? Just making wild guesses here :o

I had been a huge fan of the sd builts for a long time. But if you are keen to solve your problems related to gps,battery drain and usb issues try some of the nand builts especially Ndt gingerbread v 15. There is life on there other side of the fence.

[HD2 Android SD Development] [Krueger]Dr.Stein:
Try disabling the my location using wireless network and gps.

For SD builds this is the main culprit for standby drain.

However for usage drain like the others have pointed out NAND build is the way to go.

As for the other functions I would like to mention that whatever NAND can do SD can do too, just as well, as I have used both.

Personally I prefer SD because it gives me freedom to switch builds with ease, speed and hassle-free backup.

What could be easier than backing up and restoring Roms with CWM? It makes it easy to switch between Roms and updating is as simple as installing a zip.

2x Battery was a waste of time (and money if I remember well). I have not used any of the other two because after installing the 28 August build my battery lasts a lot longer, so much so that I would call it normal. In standby mode it is really fine now.
[HD2 Android SD Development] iivuch:
Tried it - disabling those did nothing to improve the situation. With or without them, current is around 56mA after switching off mob.internet. I played a little more - if I turn mob. internet for a short while (10-15 sec) and than turn it back off - some times it helps and brings current back to 6mA. Out of 5 trials - 3 times worked, 2 of those - it did not. In order to fix the situation I activated WiFi, gave it 10-15 sec and then turned it off again.

I have a feeling that in mob.internet mode the kernel starts doing something that requires internet connection. If I turn the connection off before it has finished - it kinda loops and continues trying - and that is why if I give it some other internet connection - it manages to finish off and then calms down. That's just a guess - but developers could possibly have a look and shut off any activity when the user deactivates internet.

A Solution: Standby - battery drain ! :) :) :)

Yey, found it ! :)

If you experience high STANDBY battery drain (56-58mA instead of the the usual 3-8mA) after having used mobile internet then read on. It would be useful if any of the devs can also see it as they might use it to find a work around.

I tested this solution about 15 times - worked 100%. Not very elegant, but it works!

After killing running apps one by one, I found that the culprit was the native Android E-mail app and a service that it runs called 'Sync Manager'. For some reason it continues syncing even the internet is off, which drains battery. You can kill it by going to your Applications Manager, tap the 'Running' tab, and choose E-mail. Then stop it. It will not die gracefully, but will give you a Force Close. That's fine - no harm done. Once it has died, you can restart it from the launcher and it will behave until next time you use mob.internet.

Does any body knows how to configure what apps are being launched automatically when OS boots up? I may have to find another E-mail app and replace this one due to the described issue.

My e-mail is configured to connect to Microsoft Exchange service. It is possible that if you are checking POP3 or IMAP servers - you might not have experienced this problem.

Roaming

Is there a sure way to stop roaming? I'm off to Greece next week and it will be the first time with giffgaff as my home provider. I see that on my Mobile Network Settings that Data Enabled makes no difference at home, i.e. it is not ticked, yet I can still receive data.
[HD2 Android SD Development] uzi2:
The fact that you haven't got Data roaming or National data roaming checked should be enough to prevent unwanted data connections.

You probably have data connected elsewhere which is overriding the data connection.

To make doubly sure you can switch off all your account connections in settings>Accounts & sync

That solution did work for me :) thanks - although I had some difficulties removing the old one and installing the new one. Not straight forward. There were no problems deleting the old Email.apk, but the system would not allow me to copy anything to \system\apps. So I had to put the new Email.apk into the AndroidApps from WM and then booting to Android - it installed it automatically. Even then - Force close's .. Then Rom Manager/Fix permission/Reboot - fixed it. Now everything seems to be tic-toc :) It would be nice to include the new Email.apk into the build.

anyway - thanks for your help.

The new market has issues with the density setting of this build. Stock ROMs have a screen density setting of 240. This build is set to 167. The new market therefore thinks it's a tablet and won't let you install apps that are not meant for tablets.

Change your screen density to 240. How-to can be found by using the forum search.

After you got the apps you want, you can change back to 167 if you like.
