General :: HTC Desire HD - Prevent Battery Check On Boot?
Apr 1, 2014
Yesterday I made some modifications to my old HTC Desire HD. I removed the battery and instead soldered a fixed power adapter to the phone (at + and - where the battery usually is). It worked well, I could reboot it, turn it off and on as usual. But then I desided to flash another ROM (an unofficial CM 4.4 port), and now the phone is shutting down as soon as it enters the launcher. It says I need to connect the charger.
I can successfully boot the phone if I start the phone with the charger plugged in (which probobly isn't healthy for the phone but whatever). Then I can unplug the charger with no problem.
So, i've tried deleting the batterystats.bin file, replaced it with an empty file with no r/w permissions at all, but it will still be replaced by the system at reboot.
How can i skip the battery check att boot, or how can i lock it to 100% forever?

This question seems a little (a lot) odd. because naturally we want our battery to get fully charged to get the most stamina out of it.
but i read a while ago that for Li-Io batteries the most efficient charge range are 10%-90% so basically that means the full charge -discharge cycles aren't good for the battery but harmful as it cause them to die faster..
anyway i considered this reading as a good theory until i bought a sony vaio laptop which had a battery preservation feature (it limits the maximal charge to 80% or 50% depending on the option) and for more that a year and a half my battery still performed well (less than 4% degradation) so i thought this was a real deal after all.
still the use cases for a laptop and smartphone are vastly different (the laptop can sit with 50% charge just fine since it will be on charge most of the time while the smartphone has to get the maximum amount of energy to last without a charger)
so is there (or can it be made) an app that can limit the charge (to 80% or 90%)

I have noticed that, while playing games on my Xperia V, the game process itself drains less battery than the Mediaserver (=audio playback) process.
Even when I completely mute the device's sound - Strange, because no sound is playing but the Mediaserver still eats up my battery. I wonder if this issue is caused by my Xperia somehow still using CPU for audio playback despite the audio is muted. is there a way to reduce or prevent this and improve my gaming battery life?

I got a new Desire S. But after update to 2.3.5 , all the keyboards removed. So I took it to the guarantee servise and they told me that they will install a new original (stock) rom on my phone and everything will be solved.
Now they say it is done and I must go to get my phone.
How can I check if they have rooted the phone or not? Also, how can I check if the installed ROM is stock or not.

I replaced my old Droid X a long time ago. Eventually the battery swelled and I threw it away.. so my old X currently has no battery. When I plug it into PC USB, nothing at all happens. If I plug it into wall power, the Motorola logo comes up, then a few moments later a big emtpy battery icon appears with a question mark in it. I can't get it to go anywhere from there.
Is there some kind of key combination I can push to force it to boot into the OS or is a battery, even a dead one, required to operate the device?

I had made changes in S/W as suggested in post : [URL] .....
The device I am working is also having wake up lag about 2 sec.It varies from 1.2sec,0.8sec,1.8sec..etc. I implemented the new wake log to prevent the phone from deep sleep as you have mentioned. Now the time required for wake up from deep sleep is reduced to 0.8s and its quite consistent. Although I have to yet check for battery consumption during deep sleep.
However I have found that now when the phone is reset the battery consumption is more during the power up of the phone. For Ex. from 36% before power up and 24% after powerup.
Checked with another device and its only taking 3% for boot up.

I was listening to music as I always do. I didn't realize it but the phone (Rezound) drained a bit faster than expected and died completely. So I went to to charge it, and left it overnight, off naturally, now when I power it on, its stuck on a boot loop.
It goes throught the startup animation, and once it gets to Sense, in the few seconds before the radios kick in and it finds the cell service, it reboots and starts all over again. Only way to get it to stop is pulling the battery out.
I started to do the hard reset, but when I got to the window for it, all I saw was Factory Reset (I guess they are the same) so I selected the option for reboot.
The light to charge does show its charging, and at one point, when I had it plugged in this morning, and managed to swipe the ring to get to my swipe lock screen, it was saying I was at 99%. then it goes all slow and then rebooted.
I used the factory wall charger, and its drained I think once or twice before, and I have done the FoxKat method of calibrating before this. Not sure if its a battery thing, since it will power up, or not.
I'm stock, non rooted, on GB.
I don't really want to do a factory reset as I'd like to have my messages saved. I did save them last week when I saw ICS was available, but i have some new since. I'm pretty sure my pictures and videos will be saved during the reset. I don't think that folder gets wiped. However I was going to try going to a VZW store to see about a new battery. The phone is new since June.

I've got a few pics on my phone that i'd prefer if curious people trying out my phone wouldn't be able to stumble upon by accident. I downloaded astro and tried moving them to a different directory but they always show up when the photos app is opened. Is it possible to make them accessible through astro only somehow?

I want to use the Smart Alarm Clock (same as the Sleep Cycle alarm clock for iPhone), but my Desire goes into sleep mode automatically. Can only pick a time between 15 sec to 30 min. The Smart Alarm Clock doesn't work properly because it requires that the screen is on during the entire night. Is there an application or something else than can disable the sleep mode when I want it?

I'm considering getting a screen protector, but I'm also wondering how much it'll affect sensitivity/responsiveness. If I do get something to protect my phone, what is the best material/brand/manufacturer to go with? Or perhaps just a leather case would be enough? That way the screen stays perfect and it's still protected when I'm not using it.
After all, I heard the screen quality is pretty good. It's glass, or am I thinking of a different phone? It might not be a "Gorilla" screen like the Samsung Galaxy, but I've heard it's pretty resilient. I think it should be ok with just a leather case, unless anyone here's already got some bad experiences with the screen?

I tried the to update software on my X2, and ota all went fine until the last step - installing the updates on my phone, there it failed with massage that it could not install and I should check my battery and then that I should try again after recharge. I tried after recharging and still the same error. Now I cannot even start my phone - after switching on it stops with SonyEricsson symbol and hangs there. I need the phone.

A Galaxy user emailed us to report that one of our apps crashes when he performs a function, we had over 10k downloads of this app with no similar report. Since the Galaxy is not yet available in the US, is there a simulator to help resolve issues like this?

As phones like the Desire can be online a lot, should we all be using Internet firewalls to prevent unwanted attention from hackers, etc.?

I try to understand android boot sequence on my JB (under CM10). I found some docs and there should be specific partitions (boot, recovery, system, cache, data).
My understanding of the boot sequence is now:
A) normal boot:
1) Power ON ->
2) bootloader ->
3) boot-partition where i flashed the kernel aka boot.img ->
4a) system-partition with the OS (libs, UI, etc) where i unpacked over CWM my customROM.zip ->
4b) data-partition, where i unpacked google-apps.zip and installed all the apps ->
4c) cache-partition with user data
B) recovery boot (adb reboot recovery):
1) Power ON ->
2) bootloader ->
3) recovery-partition with CWM where i may unpack all the .zip stuff to proper partitions, or restore from sdcard, etc.
Is this correct? I wonder, because i didn't installed CWM into recovery-partition. It cames from install of CM10 (fastboot -i 0xfce flash boot boot.img), so it must be in boot-partition and not in recovery?
So, next confusion: i looked up to /proc/mtd and i don't see neither boot nor recovery partition here:
Quote:
# cat /proc/mtd
dev: size erasesize name
mtd0: 19000000 00040000 "system"
mtd1: 00600000 00040000 "appslog"
mtd2: 06580000 00040000 "cache"
mtd3: 1a400000 00040000 "userdata"
I did a backup with CWM and loocked the data. There aren't boot, and recovery backups:
Quote:
# ls -lha /sdcard/clockworkmod/backup/2012-10-04.18.49.55/
d---rwxr-x 2 system sdcard_r 4.0K Oct 4 18:56 .
d---rwxr-x 3 system sdcard_r 4.0K Oct 4 18:49 ..
----rwxr-x 1 system sdcard_r 1.6K Oct 4 18:54 .android_secure.vfat.dup
----rwxr-x 1 system sdcard_r 54.6M Oct 4 18:55 cache.yaffs2.img
----rwxr-x 1 system sdcard_r 360.2M Oct 4 18:53 data.yaffs2.img
----rwxr-x 1 system sdcard_r 212 Oct 4 18:56 nandroid.md5
----rwxr-x 1 system sdcard_r 214.6M Oct 4 18:51 system.yaffs2.img

So, i think i didn't understand the boot sequence and partition schema corectly.

I am trying to do some low level performance testing related to device processor cores through adb which I feel it is affected by Android background services and system stuff.
As I know that the Android boot sequence stages are as follow:
1.Execute Boot ROM code.
2.Execute the boot loader.
3.Load the Linux kernel.
4.Launch Zygote, which initializes the Dalvik VM.
5.System server which loads the Android system.
So my question is how can I interrupt this sequence to force it stop on stage 3 to load Linux kernel. This can implement my intermediary performance testings before loading again Android system.
Does Fastboot or Clockworkmod recovery can load my device to a kind of Linux kernel?

Instead of seeing the boring old Android logo or my service provider's logo, I'd love to see the standard text-based Linux boot screen that shows the status of all the hardware and configuration info as my phone boots. My current phone is an HTC EVO 3D running Cool ICS with Sense 3.6 and Revolutionary CWM.

I'm with VF, luckily I didn't get the dreaded OTA last week. My phone is totally unbranded, so I'm wondering if it will let me install 2.2 manually without the need for a goldcard and all the messing about. is there an easy way to check ? I don't want to attempt an install for it to screw up and brick the phone.

I got a notification today about the Froyo update being available (yay!) but was in the middle of something so hit cancel, thinking I could get it later. But I can't work out how to!
It did say that the phone would check again at the next scheduled time so I can download it then if need be - but does anyone know how to make the phone check before then?
