Glad to be of service :D

It all boils down to use some common sense in using these little gizmos we love:

- do I need constantly high download speed even when the display is off?

If not, 2G uses less power then 3G - at least on my Desire and at my place - so I change it manually when I need it or utilize a software doing that for me.

If the tip in OP concerning GSM auto works for you - even better.

- do I need my phone to have a WiFi-connection the whole time - or even worse have it look for a WiFi only to notify me that I cannot use it without paying for it (thank you, shopping centre - very customer-oriented :rolleyes:)

If not, turn it off!

- very important: do I really need all the bloatware my provider and/or the manufacturer puts on my device? No? Then get rid of that garbage - pronto :D

- many devices have a light sensor, but poorly implemented display-brightness levels - change that. Some ROMs let you finetune your own:

http://xdaforums.com/showthread.php?t=785466

Of course it´s a common sense thing, too: you don´t need your display illuminate the rest of the room, but you want to be able to decipher it´s content :D

- don´t underestimate the OP´s tip concerning kernels. By using a undervolted/overclocked kernel with some finetunings for battery saving you can easily get 10-20% more out of your battery :cool:

As you may have noticed, many of these tips are only usable with a rooted device. Conclusion: ROOT YOUR DEVICE :D

I mean, we´re here at xda - if you want to use a phone the way the manufacturer wants you to use it: get an I-Phone :eek:

Nice tips, but most are not worth the effort ...
[General Topics] alt101uk:
Many thanx for this i had forgotten how much battery sync takes to run.
[General Topics] Victek:
I tried AutoKiller on my Inc2 (can't root it unfortunately) and can't tell if it makes a difference. One thing I notice is it doesn't save the "preset" settings I select.
[General Topics] Majorx10:
thanks for the tips. ;)
[General Topics] Xenova:
Mate, it will only works on rooted device. Maybe you can try other tricks that do no need to root.
[General Topics] Victek:
Thanks for the reply. I thought AutoKiller had limited functionality on non-rooted phones, but since it didn't appear to do anything you may be right. I believe it's now possible to root the Inc2 though, so I will have to look into that first :)
[General Topics] jthomas84:
Thanks. Good info.
[General Topics] tripster69:
Interesting to see that people are using under volted kernals for sgs2. While it's good for our phones (the ones that can handle it without the extra juice) it makes me wonder just how crappy the binning process was for the silicone in these cpus...
[General Topics] chester04:
Thanks for the info...
[General Topics] Xenova:
People always claimed that there is no downside of undervolting.. sometime i also doubt that. Do anyone know what is the drawback of undervolting?
[General Topics] germanhoss:
If the voltage reaches a certain point, the phone simply gets unstable - no other drawback that I know of :-)

The other side is overclocking. Theoretically the phone can get too hot and the cpu damaged. Practically this will lead in almost all cases to a emergency shutdown.

I think tripster69 was wondering about the actual testing process after manufacturing the first chips, where the manufacter looks, under what circumstances the actual chips are working.

I know from the Desire that there is a relative wide range of phones. I can undervolt my phone to 875 mV and it works without problems at 1190 Mhz but thats not the case with all Desires.
[General Topics] tjsantos:
not if you use your phone to read books, play music etc ;-)
[General Topics] kuj0n:

[General Topics] VVarboss:
Best article I've read about saving battery.

Curious how you use 3g if you leave it on always, or use something like juice defender
[General Topics] BS_Artist:
Effect of battery itself?

I reckon that there isn't any harm in undervolting, I've never had any problems. However, some users fall into trouble 'cos they get carried away with how much they undervolt their phone. As is the case with anything, there is a limit that each phone can take.

I'm curious though, does anyone have any idea what effect the battery itself has on this. I mean, the original Lithium Polymer battery costs around $60, but there are cheaper ones available for around $25 that claim to supply the same voltage.
[General Topics] patrafter:
I turn off all wireless connectivity when I'm finished using it to save battery power eg gps, wifi, gps, bluetooth etc.

I wish someone made a app that could automatically switch off gsm/3g at schedule time eg midnight to 6am the 3g automatically turns off. That would be awesome and save me from prank calls.
[General Topics] Xenova:
Juice Defender can do that. of cause the paid version. :)

[General Topics] Xenova:
Feel free to ask :) we will help you with the best efforts
[General Topics] Enc0der:
From my experience, the biggest battery eating feature was "auto sync", while syncing google, weather, and "facebook for htc sense" and/or "facebook" - with a large number of facebook friends.

When switching auto sync off, my battery usage usually change from around 300mA to something like 30mA (!) or even lower.

With screen turned off of course.

I use 'tasker' to make a "2 minutes window" with auto sync, every hour. This makes my phone still synced with emails, facebook massages, etc' - but also run much much longer.

What's da difference between Lithium polymer And lithium ion battery
[General Topics] Soldier Blue:
Neat, some of this is pretty useful. I was looking for a simple guide to try out, even though I don't use my phone much I am always worried about running out of juice :p
[General Topics] Xenova:
Lithium Ion Chemistry

Lithium ion batteries use an anode of carbon, a cathode made of lithium cobalt oxide and an electrolyte gel. When charging, lithium ions move from the cathode to the anode. When discharging, they move in the opposite direction.

Lithium Polymer Chemistry

Lithium polymer batteries have the same basic chemistry as lithium ion batteries. However, the polymer cells use a porous separator that, when exposed to the electrolyte, turns to a gel. Because the gel isn't flammable, lithium polymer batteries have a different architecture, with the anode and cathode developed as a plate and stacked on top of each other. Lithium polymer batteries do not need a metal shell the way that lithium ion batteries do. In fact, the shell of lithium polymer batteries is often plastic.

Thank you for this very useful post. Over the time that I've owned my DHD I'd come to accept it as a fact of life that its short battery life was inevitable. My phone usually ran out of battery after 4 to 6 hours. A week ago I decided to see if anyone else was experiencing a similar problem and came across this post. Now my battery life has more than trebled and I'm on the quest of extending it further.

how do i know which program is using the "GPS"?

4 to 6 hours is pretty normal. And I would say if you can make it 6 hours screen on. Then you have a gold DHD. Mine just 4 hours+. Even SGS2 is about the same

what for the phone keep on switching on "GPS" for hours but there's no GPS on shown on notification nor the top notification area....
[General Topics] Duckett2Times:

Indeed there is something wrong then. Because the gps chip will only consume battery when the symbol appear on the notification bar. Then, is it your battery normal compare to other using the same phone and rom?

Hi

I installed Darkky's KG2 ROM (non-wipe version). Everything seems fine, but the screen resolution doesn't quite fit in. Eg. the letters on the app drawer are way on the bottom of the screen. I'm coming from KF3. I've already flashed back to KF3 so no screenshots.

I tried LCD Density changer and similar programs, but that just sent the phone to a black screen on reboot (yes, the phone was rooted).

Any suggestions

[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] Guyden2:
I apologize if this has been stated before; however, I have been searching for the past 2 days and could not find anything. I would greatly appreciate any help.

The problem is that I do not have an SD card and installed WP7 onto the internal memory of my HD2. Every time I connect it to zune, zune tells me I have 0 free space left; however, my phone is currently telling me that I have 70+MB left. I try to sync a picture to my phone and it does not work. I tried messing with the reserved space, restarting WP7, re-installing it, etc. But the problem still persists. Am I doing something wrong? Do you need to have an SD card to copy stuff onto the HD2? If there is a way to fix this problem, please let me know or direct me to a thread that contains the fix, either way, I would greatly appreciate it.
[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] Gmic1000:
You've answered the question yourself.

A sd card is required to let WP7 function properly as it will be part of the OS.

WP7 can be picky on sd cards though, not all are supported. It can cause wifi malfunction, bootloop or WP7 can't recognize SD error message.

It's a gamble, but SanDisk Class 2 and 4 seem to work for most people. (I use a 16gb Class2 SanDisk with no problem)

Hope this helps.

[HD2 Windows Phone 7 Q&A, Help & Troubleshooting an] Rick_1995:
Sorry sire, but you are placing wrong facts on the table.

The problem mentioned in OP is because WP7 reserves some place which is around ~10% on the device for cache use and to serve as storage of emails, msgs, call logs etc.

Your problem could be that WP7 does not work well with your SD. make sure it is class 4 or greater.
