WOOO

I maybe jumping the gun a bit here but my phone says an up time of 1hour 27 mins. and normally its about an hour to about 5-10% of battery life and im sorry to say... im still on 100% WOO :D. I will still report how this lasts through to tomorrow, however i think theres enough evidence to suggest that the method stated earlier seems to fix what seemed to be a 'shortend battery cycle'. Anyone else with a short battery life i advise you to do the same asi have and please feedback to me with any results.. hope this has been helpful :)

EDIT: Its been two hours now and still 100% woooo :D:D:D
[Hero, G2 Touch General] Bad4ss:
I got escited too bratfink when I had 100% battery for ages while it was in sleep, then I dl'd a few progs from market and whoosh my battery started disappearing faster than expected. Try downloading a few things and you'll see your battry disappearing quicktime.

minfree or ramzswap off could be causing the issue.

I remember before I put that tweak on my phone (when it first came out), my battery life was amazing.

After I put the values in for init.d as from the forum page below:

http://xdaforums.com/showthread.php?t=622666&page=6

the battery life started disappearing like mad! and this was on a modaco rom!

I think now that all the new 2.1 roms are including this minfree tweak it is causing this battery issue to be carried over. All attempts to reduce battery drain are not having as much effect as they could because of this.

I would like to try one of these new roms without the tweak but I do not have the knowhow to stop it. i.e. put the original init.d (or equivalent) for the the roms in place.

You might argue that the memory clearing has nothing to do with the battey drain, but what i saw was that it did on a modaco rom. I don't know whether it is the switching of ramzswap or the minfree settings ( i have a feeling it is both.

Can a chef cook one of their roms without the tweak and keep the original settings?
[Hero, G2 Touch General] kendong2:
adb remount

adb shell rm /system/etc/init.d/02memkill

then reboot.
[Hero, G2 Touch General] Bad4ss:
I'm on the BeHero v1.3.2,m will that command put my phone memory settings back to what they would normally be without the taskkiller?

If so can I just remove that file with OI file explorer as atm my laptop usb aint working (can't connect to phone properly, can only charge)
[Hero, G2 Touch General] intronauta:
If you use Bluetooth, GPS*, or plug/unplug usb, CPU lock at 528Mhz and battery drain. This happend in all eris/roms.

I can see with Battery Graph while I sleep the battery is full, but no reason (only unlock to check time, kill alarms, read mail,...) the battery drains constantly. (no tweeter, no facebook, no GPS, no BT,..),

This kernel sucks. It's very buggy but is what is :(
[Hero, G2 Touch General] Bad4ss:
It's OK managed to fix the usb on my laptop.
[Hero, G2 Touch General] aziz831:
I am currently performing the third step...i really hope this works cuz I am getting really really horrible battery life right now...I get only about 8 hours with ocassional use...like listening to music, browsing, taking pictures, sms.

thanks for posting this thread.

Ill post the results tomorrow ( hopefully positive)
[Hero, G2 Touch General] jeremy89632:
I noticed that using the overclock widget (even with the lower clock option when screen is off) also eats some battery, it definitely reduced my usage time on Android 1.5.

Could someone confirm?
[Hero, G2 Touch General] Leeejohn:
I dont know what it is and why people have this bad battery drain.

I have the VillainRom 3.4 installed. Totally NO drain. I turned on Bluetooth and called several times. Battery drain is 8% in 12 hours :D.

I did not install any widgets. Pure standard custom ROM with newest radio.
[Hero, G2 Touch General] Lennyuk:
exactly my view.
[Hero, G2 Touch General] rubik:
I'm using HeroDroid and i had really bad battery drain problem. I'm a sort of heavy user and with bluetooth & gps permantly on, my phone had drained out by lunch time. After doing some tests, i have found that my problem was related to GPS. If i boot my phone with GPS off and left it at off, i get the same battery level usage as my original cupcake 1.5 ROM. Perharps you guys can try it and post your results.
[Hero, G2 Touch General] arshad14:
I found that to help as well. In the last 3h10m it only went down by 4%. That's definitely a lot better than what I was getting before and with the previous ROM. I am using the new Autokiller and Overclock widget if that helps any and booted up with my GPS off and followed the steps mentioned in the first post.
[Hero, G2 Touch General] immya:
hmm if its the case that the phone is "capping" the maximum amount of charge the phone can have then it should take longer to charge also

my battery life i kinda okay, lasts 10-12 hours with intermediate use, using battey graph app it took me 70 mins to charge from 40% to 100%

ill let it drain out tonight and see how long it takes for a full charge

it would be good if we could compare results with people with and without battery problems
[Hero, G2 Touch General] StrongOneX:
My main battery charger snap soo.. now im charging my phone with a PlayStation 3 controller charger.. any difference??
[Hero, G2 Touch General] DeXa:
There is a huge difference between USB charging and charging with phone's charger - USB charges with only 500 miliamps. at 5 volts, but the mains charger does it with 1 amp. at 5 volts. That's why charging from PC takes a lot longer. In my observations when charging from USB it discharges quicker - for about a day. When charged from the mains it lasts about a day and a half.
[Hero, G2 Touch General] chushev:
One question - do you get 1-2% loss with mobile internet ON?
[Hero, G2 Touch General] blueflash:
i had really bad battery life too i suggest changing radio, im using 63.18.55.06JU_6.35.08.29 and good battery life on orange UK
[Hero, G2 Touch General] bratfink:
Update

To be honest i have looked at many ROMs battery lives and different methods of trying to increase battery life. I have stumbled on a few bugs such as if you have your battery on say 75% and you flash a new rom doing a full wipe then its often your new rom starts up on 100% wheres the other 25% gone i wonder? Not only that but it just seems that the inconsistencies of battery life people have even on this same rom is incredible and i believe the issue runs deeper than just roms. Im not an expert but it could be to do with network or a problem such as mentioned above or many even shoddy quality batteries from HTC.
[Hero, G2 Touch General] btdag:
Did you flash the battery data too? If not try that, I've never had it show at 100% after a new ROM.

No evidence of this on my end. Where did you find out your stats about usb charging vs plug, i have been unable to verify this information.

I'm intrigued. Might try this soon.

FYI - to all: the 3000 mAh battery I have is amazing. I recently had my phone running for over a week without charging :)
[Hero, G2 Touch General] Noppes123:
I'll throw in my 2 cents on battery life and charging issues. :)

1) USB 2.0 specifies a load of 100mA per unit, with a maximum of 5 units per port, hence 500mA. If other devices drawing current are connected to the same passive hub, you'll share the load (the USB 3.0 standard increased this to 6 loads of 150mA). See the usb.org site if you don't believe me. :mad:

2) Most AC-powered USB adapters - including the one supplied with the Hero - can pass 1A at 5V, twice the current of a USB 2.0 port, but whether this makes any difference in charging time is up to the built-in battery charging circuitry and (kernel) software. I should measure the actual current drawn some day ;) to be sure.

However, apart from any alleged difference in charging time, once the battery is charged, it will have the same discharge characteristics - that's the beauty of Li-Ion batteries :).

3) Any stated difference in power/current/voltage stability between the PC USB port and the AC adapter, if true at all, is irrelevant because any modern charging circuitry does all the measuring and regulating to charge the battery properly.

No offense, but the trial and error testing methods applied by some is a bit doubtfull. Results are subject to differences in interpretation, actual phone usage, settings, running processes (!), use of built-in devices, application bugs, brightness settings, screen time-out, signal strengths, etc. The biggest problem in any test scenario is making sure the conditions between tests are as identical as possible.

As an example: to measure the actual difference in charging time - if any - between the AC-adapter and the USB-port, the phone should be switched off during charging to make sure the conditions are identical. And to get a bit fanatic: the room temperature should be the same. :D

Where am I heading with all this? The point I'm trying to make is that we should focus our 'energy' :cool: on the software, configuration or kernel. If the battery discharges fast(er) there is something keeping the Hero busy, be it a background or sync proces, bug that keeps the device from going into sleep mode or whatever. The logs and detailed device current usage patterns should tell us more, but can be hard to interpret.

When I'm going to flash a new ROM I'll check wheter I can reproduce the possible bug where the actual battery level is reset to 100%. For other tests, I may not have enough free time at hand. :(
[Hero, G2 Touch General] btdag:
Very interesting. Thanks
[Hero, G2 Touch General] frederikk:
Hi,

I don't have any "scientific" explanation, but i can clearly see that when charged from usb port's the battery life is shorter than from the htc power charger... can't explain or prooved it, but test it and you will see.

Ciao

Fred
[Hero, G2 Touch General] phaelox:
Yeah, I'll go with Noppes123's well reasoned write-up. I think your experience might be more perception, than anything else. Even if there would be a difference (after all Li-Ion batteries are supposed to have no memory, but even they lose capability over time, although not as much as Ni-Cd batteries), I believe it'd be negligible for the reasons Noppes123 described.
[Hero, G2 Touch General] Deeko1:
Thanks mate - I have downgraded to this ROM and my battery life is much much better. It went from 56% at 20:16 (when I flashed) to 50% at 07:56. Contrast this to 98% at 23:01 to 83% at 07:56 the night before. As you can see - a much bigger drop over a shorter period with the lastest ROM!
[Hero, G2 Touch General] frederikk:
As i said, i can't prove it but this feeling (like you say), i have it everytime i charge my phone via usb... And i only have one android phone so can't make the test of charging it with usb, let it drain without using it, and make the same test with the power charger...

And about the rom adviced, it's ok in 2G but wifi drains the battery very quickly !

Ciao

Fred
[Hero, G2 Touch General] Noppes123:
Sorry to be a party-pooper again :D but the workings of Li-Ion batteries is well defined: they have no memory like NiCad and charging time is not reduced if you feed them higher than 1C current. In fact, high currents may cause some charging circuitry to skip phase 2 (where the cell voltage rise is flattened and the last bit of capacity is charged) and go directly to phase 3 (brief charge pulses from time to time to compensate for any leakage).

But, since USB 2.0 can supply no more than 0,5A and the HTC Hero AC adapter 1A, both are below 1C (the battery's capacity). So, apart from a small difference in charging time, both will come up with the same capacity in the end.

I keep repeating myself, but...ROM differences, actual usage, bugs, running services/apps, signal strengths, usage of the many built-in devices, and possible bugs in the charging circuitry driver (which may cause the Hero to top off too soon after ROM flashes or hard resets), are the directions to go.

Will try to verify whether ROM flashing influences the measured max charging level, as reported by some, when Villain 5.3 is released.
[Hero, G2 Touch General] torstenk:
The ones i know who have an iPhone get a battery life of about 2-3 days.

Why can the iPhone have a battery life of about 2-3 days with normal use, and most here only get 1½ days? I can get maybe just squeeze 2 days off my hero if i dont use it at all
[Hero, G2 Touch General] [funcoder]:
My battery life time is 2 - 3 Days on my Hero. I am using the origin 1.5 ROM from HTC. I do only switch on the 3G connection if i need a Connection(eg reading mails ).
[Hero, G2 Touch General] phaelox:
Because the iPhone doesn't allow you to run *user* background processes (aside from playing music; and not counting new e-mail checks). This comes back to what Noppes123 has been saying, Android lets the user do more, and as a result, the battery drains faster. Uninstall apps down to what you absolutely need and you'll see an improved battery life. And as [funcoder] says, don't turn on 3G unless you need it. Oh and as a last note: widgets are apps, too! Put only as much widgets on your home screen as you really need, uninstall others (3rd party widgets).
[Hero, G2 Touch General] gr3yh0und:
TBH, Iphone Battery Sucks. HTC Got a better battery, I use them both. Just a few minutes of wifi and Iphones Drain's more than HTC Hero. HTC Hero can survive a day or half with 3G On and surfing. While Iphone does not last a day, just say 10 hours.
[Hero, G2 Touch General] frederikk:
As i said, i didn't say that if i charge my phone when it is not completely empty it lasts less and less.... i just said charging it by USB or by power is not the same effect, and it drains faster when charged by usb. That's all. So for me there is nothing to do with memory effect on what i said.

[Hero, G2 Touch General] drspikes:
The way I have solved all battery problems and speed issues is with something on the market called overclock widget. Search the forums for help on this but basically you need to go to the advanced option, set the clock speed low for when the screen is off and max when the screen is on.

I have a great VillaineROM 5.3 experience and better battery life - good enough for me although have not formally tested.
[Hero, G2 Touch General] phaelox:
As far as the Hero goes, OverclockWidget and SetCPU only work with Android 2.1 (which is why it works for you)... I don't wanna go to the 2.1 ROMs yet, and with 1.5, unfortunately even with the overclocked kernel by maxisma, you can't use those apps to underclock.
[Hero, G2 Touch General] Dan330:
I used them both in 1.5

They worked just fine. I did like overclock more..

And I feel that it saved a lot of battery life.

I am also using it in 2.1

Not sure if it helps in 2.1

But it cold not hurt.
[Hero, G2 Touch General] Krishna.duvvuri:
There is an app on the market called Battery Calibration that does it all for you :)
[Hero, G2 Touch General] o0rebelious0o:
Does It Work?

I've seen a lot advising people not to use "task killers" and the like as one is implemented by the OS (hence just wasting battery) and it is a well known fact that battery performance is improved by allowing it to drain fully before charging (not hard with the battery life I tend to get), however, I've never tried apps such as battery calibration and I definately didn't know about the bug if you boot while charging. Well have to give it a try and see how it goes :)
[Hero, G2 Touch General] shantur:
Try Battery Calibration...

It works really well... It increase my hero's backup just to double

Kinda short notice, and who better to ask than the fellas/gals around here...

Need an answering machine (not a phone in one) that has these capabilities:

1. Multiple mailboxes

2. Multiple Outgoing messages

3. Ability for the caller to choose which outgoing message they want to hear

example: Joe Schmoe calls, answering machine picks up, and then is given the option to press *2 to listen to outgoing message 2 and/or *3 to listen to outgoing message 3...and then leave a message on the box that corresponds to the message they just heard.

Very important that the outgoing messages be able to be personally recorded, and not just some 'mailbox 2, record now' message.

Thank you!!!

i've had customers come in and ask i personally obviously dont know the answer but maybe ya can help. is it possible with android to view security cams like a winmo phone can?
[Hero CDMA General] poor_red_neck:
Be more specific.... Need more info on how the "security cameras" are broadcast.

How did you view the cameras on your winmo phone?

Was it through an application? Streaming?

If it is streamed over a network, then with a 2.1 ROM you should be able to view a flash video stream.

If it was an application written for windows mobile, then unless someone makes a version for android more than likely not.
[Hero CDMA General] Kcarpenter:
There are several apps in the market that allow you to view a cam if it is on an IP Address that can be accessed outside of the network or in conjunction with an FTP Server if the cam uploads pics to an FTP server. "Security Cams"/ Web Cams are in general one in the same. The Security cams could be a little more sophisticated as far as weather conditions and visible specturms, but... potatoe potatoe...damn it i did it agian.

[Windows Phone 7 Development and Hacking] starchildx:
hi,

Sorry that i open a new thread for it but i hate the discussions about the numbers of buttons of the hd2 and WP7.

And i hate that microsoft isn't telling us the truth.

So,

The HD2 have 7 Buttons.

1. (On the left side) Volume (there are actually 2 buttons, but who cares ;))

2. (in the middle ;)) the Screen

3. Phone Button

4. Home Button

5. Start Button

6. Back Button

7. Power/Sleep Button

Let's take a look on the "UI Design and Interaction Guide for Windows Phone 7 Series" on page 20.

The WP7 have 7 Buttons.

1. (On top) Power/Sleep

2. (On the left side) Volume (again, two buttons)

3. The good old screen

4. (on the right side) the camera button

5. Back Button

6. Start Button

7. Search Button

So, the difference is the layout.

at windows mobile 7, the home and the start button would do the same, so one of the two buttons could be the search buttons and the windows mobile 7 dont use the phone buttons, so this could be the camera buttons.

sorry for the bad english ;).

starchildx

EDIT : if someone wants to see the guide here it is
[Windows Phone 7 Development and Hacking] GuestK0081:
as it has been said before, the reason isnt the buttons, but the hardware image scaler, and the presence of an sd card slot
[Windows Phone 7 Development and Hacking] bedoig:
Um... Count again?

[edit]Maybe I'm getting ahead of myself since I don't actually own one. Doesn't the HD2 also have a dedicated power button (other than the End key) at the top of the phone? No?
[Windows Phone 7 Development and Hacking] H3ALY:
Nope the "end" button is also the power button.
[Windows Phone 7 Development and Hacking] vangrieg:
And therefore you decided to start another one?
[Windows Phone 7 Development and Hacking] bedoig:
