Supposed to work with stock branded phones but you just cant calibrate your battery but again stock phone has a perfectly calibrated battery already so unnecessary..hope it helped and as zeekiz said you need to turn of your phone completely with fastboot turned off in the settings...

Do I need to calibrate after a rom restore?

I know you should after a new install but what about a restore? Cheers
[HTC Desire S] olyloh6696:
Always wondered about that too!

But if you think about it, and the backup backs up everything including the cache etc, so it would presumably backup the calibration etc
[HTC Desire S] rayulove69:
understanding that you are doing a nandroid restore I dont think thats necessary .. but if you think battery is misreading then its a good habit as always for mental peace;)

Yep, just restored my nandroid, and battery is draining fast or Being read inaccurately.

So i guess I will still need to calibrate it!
[HTC Desire S] shuprio:
This is nothing but just calibrating your battery. And following all those steps will really make a phone a very regular phone rather a smartphone. :P

Anyway. Thanks for sharing.
[HTC Desire S] rayulove69:
I dont see people from bangladesh that much here . Glad to see you man . Now it would but most option should be disabled in a not needed to disable and needed to then enable basis . And the first portion as I thought actually makes the battery to charge at a max thats why I saw that improvement from previous state . anyways . and there is thanks button you know you can press that :P

[HTC Desire S] sadsac:
Thanksfor replies, yes I think I do need to recalibrate as it doesn't seem as accurate as before I restored.

In particular, when charging it takes longer and longer to charge up per % (looking at the history on battery monitor widget) after about 75%...
[HTC Desire S] rayulove69:
yeah so recalibrate it using my method and see how it goes :)

[HTC Desire S] azunic:
I did not notice any changes to my battery life... :(
[HTC Desire S] rayulove69:
Followed this guide?
[HTC Desire S] olyloh6696:
Endymion, I have it on all ROMs, its normal :p
[HTC Desire S] rayulove69:
Umm...I am on endymion to atm but battery doesn't drain that a much with mobile network off ... Say I have 65% when going to sleep ... Waking up and after a moderate to low daily use I can go up to night 9 ...
[HTC Desire S] kylon:
So....we have to charge our phone for about 30+ hrs??

How can this increase the battery life?

Are you sure?maybe you are using the power-saver of android and you have an undervolted kernel...
[HTC Desire S] rayulove69:
I dont think you read the guidr quite clearly cause in my calculation charging time is 8+1+1=10 hours :)
[HTC Desire S] Asddsads98:
Been charging for 9 1/2 hours now, hopefully battery life increased by the time it's done :D if so, this guide deserves a thanks :)
[HTC Desire S] kylon:
Anyway,i think this can t help us.

I have all battery saver tweaks,and i sill have a battery drain

So,why a charge can help?
[HTC Desire S] Jahai:
Maybe it is a method to activate all cells from the battery ;)
[HTC Desire S] kylon:
Someone said that "charge a battery when it is 100% can damage it"
[HTC Desire S] olyloh6696:
True, extreme overcharging (+24 hours) can damage your battery
[HTC Desire S] Cole07:
Thanks for guide. But I think somethings can cause problems to users.

1) After %100 battery charged, it stops charging. that only cause more temp and affects battery life

2) I agree to disable fastboot. Device is kinda hibernating while fastboot enabled.

3) That is a myth I think.

Typical guide of improving battery life:-

1.Turn off Background Data syncing: That disable sync like pop3 mail.

2 Ditch Auto-sync : That disables sync like pop3 mail too. But it helps to lower data costs.

3.Get rid of Vibrate: Some users will want to use it. But disabling it effects batter life

4.Turn Off Haptic feedback, it's largely unecessary unless you

must have it: Settings > Sound > Untick Haptic

feedback : Some users like me will want to use it. But disabling it effects batter life

5.Lower Brightness: that works too but automatic brightness works for better visual at low or high lighting conditions.

6.Lower the Screen Timeout Interval: That works too

7.If you're out and about then you can disable WiFi : that works too. Should disable it after use.

8.Disable Bluetooth, who uses this these days anyway: that works too. Should disable it after use.

9 Clean up the Running services: Some people says cleaning up the running services cause more cpu usage so it uses more battery. I'm not sure.

10.Check the data options of the apps you have installed, many

can be customized to reduce battery usage: Totally agree. You don't have to check mails so often like 15 min.

11. Disable always on mobile data: yes it works too. It doesn't effect many auto sync apps.

12. If you are on GSM or 2G then : I agree

13. Use a Mobile network toggle widget to turn it on or off when not needed . It improves battery a lot as I find the latest radio to be a better battery hog in this case: yes it helps but disables auto sync.
[HTC Desire S] WibblyW:
For me by far the biggest battery life consumers are

1. Display

2. Having the phone in a poor signal strength area

Not a lot I can do about 2, but for 1 is there an app that can replace the auto-brightness with a version I can tune? I have a stock non-rooted phone.
[HTC Desire S] rayulove69:
@cole07 all you say is right but do you know the battery bug that causes rom to show 100% even when its 75 or something?see my another post about it. My guess here is if I keep the device plugged in it automatically reaches 100%(full) at some point in that 8hr period. Or you can also try to have your battery completely empty and then charge it to 100%.and if charging stops after 100% it isn't doing any harm is it? And hardware these days are sophisticated ver much so I don't think that keeping it plugged 8 hour does that much harm to it.

@wibblyw umm I don't know any app about it but you can always use custom roms that provide lowest settings for auto brightness. You can't do much with a stock unrooted one you know ;)
[HTC Desire S] WibblyW:
Not free, but just found one that seems to work

https://market.android.com/details?id=com.vito.lux

---------- Post added at 02:26 PM ---------- Previous post was at 02:17 PM ----------

I agree. As we know/has been reported Lithium cells tend to explode if overcharged, so the charging circuitry tends to be carefully designed to stop this. I also find the temperature reported by the phone is within 5C of ambient after being left on charge all night, re-enforcing the view that there isn't much power being absorbed by the phone in such circumstances. When in use or during charging the temp goes up a fair bit.

Taking the battery through a FULL charge discharge cycle might help any phone recalibrate what it thinks are dead and fully charged states (and help improve battery life) but be aware Lithium cells don't respond well to such cycles (reduces service life) so don't do it too often. Cycling like this does NOT recondition the battery (it actually hurts the battery a little) - what it does is help 'recondition' the phone's measurement of the battery state.
[HTC Desire S] Cole07:
From your guide; With the Desire S switched on, charge the Desire S for 8 hours or more . Your battery should be 100% by that time . If it is don't disconnect the charger . Keep it plugged in for 8 hours or more. It gives the battery time to cool down too so its a good thing.

Mostly I start charging my DS at 11pm to 7am. 8 hours ok, probably it will not cause a problem, I agree that, hardware will not let a damage. But as you wrote if it doesn't indicate %100, keeping plugged again for 8 hours, may harm battery. After 8 hours charging period, battery temp gets high. And more 8 hours charging, can cause more temp. I didn't try 8h+8h charging and inspect temp values. Pls don't get me wrong, I'm not trying to correct you, just trying to understand that high battery consume mystery:)
[HTC Desire S] rayulove69:
You can do one thing .. say try to make your battery hot by simultaneously using and charging it .. when you reach 100% see if its still hot then keep the charger plugged in for say 2 hour .. you will see your battery has cooled down!
[HTC Desire S] kylon:
Why don t undervolt the kernel?....

It is the easiest way.and you ll have battery drain only with mobile data or wifi(it is normal,unlucky...)
[HTC Desire S] rayulove69:
My guide was primarily for non rooted stock people so undervolting isn't much of an option there but one who's rooted and have will to save battery will also know about these undervolting right?;)

I use endymion with -50mV undervolting by Oc/uv beater.
[HTC Desire S] Supermatt01:
works but

it won't double the life of the battery. it was helpful and gave me some more standby time and helped condition the battery for more use time but not a heck of a lot more. it's still no where near the manufactures claim of 400 + hours standby. I was getting 107 hours standby and about 4 hours use after the conditioning trick I get about 120 standby and 5 hours use.
[HTC Desire S] eyahl:
Guys, btw, our desire s has a lithium-ion battery. Those won't continue charging when they are full. You can leave them plugged in without any harm.

But fully discharge the battery can reduce the maximum capacity.
[HTC Desire S] Supermatt01:
8 or 16

8 or 16 hours now I'm reading this first post again. charge to full if 100% charge for 8 hours then charge another 8 after full then unplug follow the other directions or is it just for the 8 hours cause my battery is now reporting that the voltage is at 4.108 instead of 4.204 the standby time is at 118 hours what should I do to get the manufactures 400 + hours?
[HTC Desire S] suku_patel_22:
well for most people out here have PC's power outlets, TV's with USB ports

Does it really matter, how to charge and when to charge

Plug it when when you have the chance..
[HTC Desire S] rayulove69:
You can hardly if ever get the manufacturer claimed battery life .... its the truth always
[HTC Desire S] Supermatt01:
ok cool

but could some of you guys post your top standby time so I can get a general temperature on how long is standard for the DS cause I'm thinking about buying a muggen cell.
[HTC Desire S] dr.higgins:
@OP: I see people writing 8+8 hrs, and you don't correct them ('cept for the 30 hrs comment).

But what you're actually saying is 8 hrs, wether the phone is fully charged, or not, right? (+ the additional hrs)

Or did I too misinterpreted the op?
[HTC Desire S] WibblyW:
Standby time will be significantly affected by how strong the cellular signal is where the phone is located. Manufacturer's standby time will be based on very strong signals so the phone isn't itself having to transmit at high power to maintain dialogue with the nearest cell tower.

In marginal cell signal areas with no WiFi, my DS will lose 50%+ in a day not being used. In strong signal areas, with WiFi (so background data doesn't go over the cellular network either) it will drop maybe only 10% in a day.
[HTC Desire S] Forcefire:
Some great tips on how to extend your battery, I'll get a few a try :)
[HTC Desire S] Nplus1:
Guys, I would really recommend using a brightness control app; to me it does wonders.

I'm using LUX with a convenient configuration (a bit lower than the default brightness in low light conditions and maximum brightness for direct sunlight - can't drop below max if you still want to use the phone outside).

Right now I'm getting 60% of battery used in about 51 hours (see attachment) with light usage:

- 30 min of talk time (3G)

- 9 hours of Wi-Fi on

- about 30 MB of traffic through Wi-Fi

- 4 minutes of GPS

- 10 SMS

- and this is the cool part: screen on for 2 hours in total

With the default auto screen brightness I was nowhere near these figures.
[HTC Desire S] Kavrocks:
I came across this thread and was utterly amazed by what I read. As has been pointed out the second part of the OP basically tells you you have a smartphone now lets turn off every feature on it. What kind of guide is that?

And the claim about the charging method in the OP doubling your battery life is absurd and there has been no proof. None of these type of methods can extend the life or capacity of your battery. Proper charging and discharging can slow the decay but it can't just suddenly give you a higher battery capacity. As long as your battery is charged to 100% (I'm not talking about what the phone says) you can't get anymore charge into it without damaging it. The circuitry in phones also prevents extreme overcharging.

Stock phones do not have a perfectly calibrated battery. The battery is designed for the particular model of phone but as each phone and battery are slightly different each combination would have to be manually calibrated before shipping which does not happen. They are made so as the majority of combinations produce very similar results.

It can't, no one time charging method can after its been charged/discharged once.

Its not a big it is done on purpose so people don't freak out when they notice their percentage of charge remaining has dropped dramatically since being unplugged.

This thread is rife with mis-information. Your phone is yours use it how you like.
[HTC Desire S] totalnoob34:
Don't let the title fool you, you can't get any benefit from charging your battery for 8+ hrs even though it is fully charged. Just calibrate your battery after changing rom, and enjoy your battery!

[HTC Flyer, EVO View 4G] mur4d:
So far I managed to control the button leds (but the touch function has not working yet):

To turn on :

echo 20 > sys/devices/platform/leds-microp/leds/button-backlight-portrait/brightness

To turn off :

echo 0 > sys/devices/platform/leds-microp/leds/button-backlight-portrait/brightness

Anyone know how to make the capacitive buttons work in HC? If it is working, we can use the buttons when we hide the status bar.

Update as of 28th Dec 2011 : Capacitive buttons has been succesfully enabled by LeeDroid on his HC v2.0.0 kernel. (Thanks LeeDroid for your great effort!!!) Required driver for keys was missing in official HTC HC kernel. I hope HTC will include the driver in their next release.
[HTC Flyer, EVO View 4G] DigitalMD:
The bottom bar is considered a permanent screen decoration in the same way that capacitive home/menu/etc. buttons below the touchscreen on Android phones are so there is no option to remove the bar, but there is a call that some apps use to darken the bar like some video players so it not intrusive, but you still lose that part of the screen.

There are hacks and apps for rooted HC that can hide the bar. Not sure you can recover the screen size or just darken the bar. Because the bar is at the system level, such a hack might cause issues with a lot of apps. its the same for all devices running honeycomb.
[HTC Flyer, EVO View 4G] AidenM:
Also how would you get your notifications, clock, quick settings, etc?
[HTC Flyer, EVO View 4G] mur4d:
You can hide the botom bar using app such as HoneyBar. Hiding the bar really saves space, especially for our small 7" screen. We can enjoy full screen size when browsing, viewing images, watching videos, read ebooks, playing games, etc.

Currently I'm using Button Savior to replace the missing navigation buttons when the bar is hided. But I'm thinking it would be better if we can use the capacitive buttons. (Having 2 sets of capacive buttons is actually a unique feature of HTC Flyer, but it currently useless in HC).

Hiding bar is temporary, we can back to normal like the HoneyBar app do. If the capacive buttons can work on HC, maybe we can make the app to auto enable the buttons when the bar is hided and disable the buttons when the bar back to normal.
[HTC Flyer, EVO View 4G] Maedhros:
Wondering if there is any update on this ?

This seems like a great idea... even if we dont disable to onscreen buttons, there are TONS of uses for the capacitive buttons!
[HTC Flyer, EVO View 4G] pfroo40:
I would love to be able to use the capacitive buttons and have been hoping someone would figure out a way to enable them in HC. Honeybar works great, but 90% of the stuff I need the bar for the capacitive buttons would work fine for and wouldn't cut into our limited screen size.
[HTC Flyer, EVO View 4G] morbidz:
Just went back to GB due to this. It's a shame It's not a customizable option on HC
[HTC Flyer, EVO View 4G] Maedhros:
I think the key has to be in the code for the pen button.
[HTC Flyer, EVO View 4G] DigitalMD:
Obviously its not a standard features in HC since its' hardware specific. We would need all the source code from HTC to compile a new HC ROM which we don't have. Someday this might happen, but not yet. You will get used to the HC implementation.
[HTC Flyer, EVO View 4G] Maedhros:
That's sad to hear, especially considering the HC implementation is pretty ****ty. Many times in HC you only need the home, menu, back buttons. The majority of time the status bar isn't needed.
[HTC Flyer, EVO View 4G] globatron:
No source, no buttons. It's just not worth the effort for any dev.
[HTC Flyer, EVO View 4G] Maedhros:
So does that mean we could achieve this if someone brings ICS to the Flyer?
[HTC Flyer, EVO View 4G] DigitalMD:
No, the hardware buttons are HTC hardware specifc. You would need HTC source. Goggle has no buttons , therefore the system bar that is omni present.

Everyone needs to understand there are a lot of pieces that must be in place to build a working ROM for a device.

When Google throws out a OS version, it works on zero, nada, nothing, no device in the world.

Then the HW makers (HTC, samsung, etc.) have to add their pieces of software to make it work. Kernel, drivers, bootloader, Sense UI, framework, libraries, etc.

HTC has to take ICS and make it work on the hardware. Then if the hardware is similar enough, you might be able to port the ROM to run on another HTC device. But without the source for the HTC specific pieces , you cannot tweak it very much or fix bugs.
[HTC Flyer, EVO View 4G] luxio:

[HTC Flyer, EVO View 4G] bsoplinger:
I have no idea if this info is at all meaningful or not but the Dell 7" Streak got a Dell approved update to HC 3.2 and they managed to keep the hardware capacitive buttons working. And they are handy, in that I agree. It'd be great if the Flyer/View had them working.

Hardware Buttons & Calls on Honeycomb

Dear Devs,

Please is there any hope of getting the hardware buttons on the flyer active on HC? Also is it possible for calls to be made; now that the source code has been released by HTC?

Thanks.
[HTC Flyer, EVO View 4G] globatron:
1. Maybe, haven't looked into yet.

2. No, the problems with calls are not kernel related.
[HTC Flyer, EVO View 4G] porcupineadvocate:
So a couple of people on this forum have linked to the Dell Streak 7 having Honeycomb and functioning hardware buttons. Amusingly people on their forum want to disable their buttons instead...

Anyway the suggested method is to edit the appropriate keyboard layout file to add/remove the Home, Back, and Menu buttons. I checked and, lo and behold, flyer-keypad-v0.kl in GB and HC differ by precisely the Home, Back, and Menu buttons.

Unfortunately it does not work to merely restore the three lines in flyer-keypad-v0.kl. So... just an FYI. There must be something else missing. Damn it, HTC! Why couldn't you have taken the easy way out disabling the buttons.

The keychar files in GB are compiled binaries whereas the HC ones are plaintext; no idea why.
[HTC Flyer, EVO View 4G] appelflap:
Do you still have access to a Gingerbread version? The keyboard files are mapped by one of the files in the /sys directory. Maybe you can find in which file the kl file is mapped. I used these mapping as a heuristic for the buttonremapper app. If you can't find it I can modify this app to recursively search all files in the sys directory for the flyer....kl mapping
[HTC Flyer, EVO View 4G] porcupineadvocate:
No, I don't have a GB Flyer.

For what it is worth, the GB Home/Menu/Back buttons have the same codes as the ones you list as standard in your app.

What file in /sys is it, anyway? Or what can I search for? I could try dumping /sys to /sdcard and searching that, haha.
