Battery life fix

[tomksoft]

Today I have been away from home with my HD2 for few hours. I have noticed that without intense use(only checking mail few times and listening to a bit of music for few minutes, had HSDPA on and Palringo on), I went down from 100% battery to 40% in about 6 hours. That did not seem to be good. I have checked battery life fixes for other phones and checked which are available for HD2.

Here's what I changed in regs:

HKLM\Comm\AsyncMac1\Params
DisablePowerManagement=0

HKLM\Comm\PPTP1\Params
DisablePowerManagement=0

HKLM\Comm\L2TP1\Params
DisablePowerManagement=0

HKLM\Drivers\SDCARD\ClientDrivers\Class\SDMemory_Class\High_Capacity
DisablePowerManagement=0

HKLM\Drivers\SDCARD\ClientDrivers\Class\MMC_Class\High_Capacity
DisablePowerManagement=0

HKLM\Drivers\SDCARD\ClientDrivers\Class\SDMemory_Class
DisablePowerManagement=0

HKLM\Drivers\SDCARD\ClientDrivers\Class\MMC_Class
DisablePowerManagement=0

HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Battery
PollInterval=20000
// probably time between checking battery status, it's 10s by default, changed it to 20s

Tomorrow I will test it out and report if applying these fixes helps or not. You can check them out too if you want. So far I did not notice any problems after these reg changes, but I am not sure if they help.

I think the same can be applied via Advanced Config.

 

[tomksoft]

I do not know, perhaps. However, not all hacks I have found are available for HD2. I'd not risk playing with advanced config tools that are not compatible with Leo.

will be interesting to see how the test goes - just dont forget to make a softreset

By the way I must ask You... Where did you bought the HD2 so early in Poland? I'm still waiting for mine...

hope, it will be better take a look, if it doesn`t close (or minimize) programs like opera in sleep mode, and if mail is still synchronizing... it should be good, but one never know...

You can also use "Advanced Configuration Tool v3.3" t do so.

My battery have a "problem" and "solution" on drain.

I charge to 100% and then go down to 50% or something really fast. Then from 50% to 5%, last looooooooooooooong,

like

100-50% = 10 hours
50-5% = 25 hours.

have you trying this? Maybe it is the problem and not a really fast drain.

This is a know thing on phones using the Snapdragon chip.

i dont get it.
i really dont like the battery life of the leo,mine is finished within hours
and im not using it intense.

It is not that bad for me, lasts 10-15 hours depending on usage. And mine is used intensely: 60-80 minutes of call, corporate push email; 4 private mail boxes and weather synchronized every hour, RSS feeds checked 3-4 times a day, etc. I expected something like this from the combination of a 4,3" screen and a 1230 mAh battery.

An idea

Hi All,

Those of you experiencing battery life issues - are you using the Facebook/Twitter/Weather sync tools in Sense? It appears they don't drop the connection once they have done their sync.

So any of (or all) these tools running means your data connection is constantly on... If your using 3G that's a big drain on your battery!

Try turning off this functionality and see if that improves your battery life, if so then you know what the culprit is.

You could always switch 3G off and turn it on when you want to web browse etc... which would also help rather than turning the Facebook/Twitter/Weather functionality off completely.

Unfortunately it looks like bad coding from HTC...

Hopefully either they or 'us' can fix it soon

Battery life

After a brief honeymoon with HD2, I am back to earth.
Though I love this device, if battery life is due to ordinary use, I'm stuffed.
I'm used to the HD which had really good battery life.
Hopefully it is only settings.

Data is only a battery drain if bytes are being sent/received. If the connection is idle it doesn't do anything.

Wellthe battery if I remember is only 1230mAh (or was it 1250) compared to the Kaiser which has 1350mAh and as we all know within a few months there are higher capacity ones available. So keep an eye out on places like batterymill.co.uk etc for bigger batteries.

 

[tomksoft]

Today, after same usage as yesterday I have 83% left! Seems these hacks really work.

 

[Ruudfood]

For those complaining about the battery life, did you characterise the battery properly?

Its well documented that you do not need to do this with Li-Ion batteries. All you can try and do is "reset" the circuit which is used to try and "estimate" the amount of battery life remaining based on voltage levels. This is inaccurate at best and just wrong at worst.

Why would power management have been disabled in the first place? Any ideas? Have HTC put in their own power management?

My first day with the HD2 today, and I charged it from 40% (as it came) to full overnight. An hour of audible audiobook whilst plugged in, 30 mins of music, browsing, 30 mins of calls and regular email checks on battery, and I'm down to 15% after 10 hours. This seems rather low. I've put these tweaks in, and disabled auto-refresh on twitter and weather (everything else is off), so we'll see what happens tomorrow.

 

[tboy2000]

Despite adding the battery optimization tweaks I have read in this post and ones I have out in my hints and tips thread, I still am so disappointed with battery life. It just runs down too quickly. The autodisconnect data reg tweak seems to work sometimes and othertimes it doesn't

Lets all try our very best to discover, research on other forums the best way to improve our battery life.
