Hello everyone.
I am using the WM6 in my Hima since 5.10 and I observed some conclusion about the power management in this ROM. While WM5 keeps a reserve in battery for keeping the RAMdisk under power,even the device stay off,the WM6 keeps it not. Also in WM5 it seems,that this reserve damages the battery-few months of use with WM5 the battery turns off not from 0%,but the switch-off limit raises and now my battery kepps power only to 40%. Now with WM6 I am able to discharge the battery to 30% of capacity,but the battery has no reserve to keep RAMdisk contents and all was gone after few minutes(discharged backup batt). I think now,the battery lifetime can now raise again to its normal capacity. While I will not use RAMdisk,I am okay. Everyone knows,if is the power management really different?
Thanks in advance.

Could we use this thread to detail the real life battery benefits of using WM5 on the Blue Angel?
Supposedly WM5 is going to be the schizzznit for battery life. Lets see if that is really the case.
Well, I'm running it at the lowest backlight, and it seems that the battery lasts about 20% longer.
Hmm
Seems a little thin for an OS that is supposed to increase battery life by 50%. Of course this OS is still in beta. My guess is there are optimizations for individual hardware profiles that could change that significantly. Lets hear from others and see what improvements come in future release candidates.
Noticed no difference ...
Ran for 2hrs 17mins & now the battery level is at 60%. Only 15mins of that time is with WiFi on.
May jump back to WM2003SE soon...
I don't think that this ROM would run any longer that 2003SE. Our device still needs to keem RAM powered. The time would be increased on newer devices that would have less RAM. Read the story on buzz site.
I know those Pocket PC devices drain their power very very quickly, but when I wifi for let's say about 5 minutes on some websites, my power is drained like 10 percent maybe. Is that extreme or 'normal' for the kaiser?
On the other hand I must admit that when I do nothing with my kaiser it can last very long without recharching.
Which rom and radio are you using? These devices are not exactly renowned for their great battery life (the cost of 3g and hsdpa), but there are ways to optimize them...
PDACORNERultimate. But I also used a HTC P4350 earlier, and it was all the same with the battery life , just wondering how I can measure what battery is better because I have 2 tytnII's until tonight, so I was wondering how I can measure what the best one is .
ALL batteries lose the ability to keep a charge as they get older. Any battery over a year old should be highly suspect.
Get the Tytn II that appears newer, then get a BRAND NEW battery for it

A new battery cured my fast discharge problem. At the time Amazon had the best price on batteries.
I've observed with my TyTnII (1yr old) that the battery drains faster from 100% to 70%. However, it retains charge from 70% to 0% for a longer time.

A 10% change on the meter means nothing. To evaluate your battery life/drain, start with a fully charged battery and run it down completely until the PDA switches off.
As said above, the percentage reading is approximate and won't always go down in a linear way. It can go down from 100% to 30% in one hour, then take 3 more to go down to 0.
I think you are using the wrong charger. The charger u are using is nog strong enough. I had the same problem. You need the original charger.
Is there a software that control how your battery will be charged?
I know there is a tweak that allow your device to connect to your phone and sync without charging it.
However, I'm looking for a program that will let my battery drain till like 2% before it start charging. The reason I want this to happen is because it'll improve the performance of my battery. It's always good to drain out the battery before fully charge it again.
I don't know about any app that will do that for you, but no charging while syncing can be done in the settings:
settings/system/energy -> Don't charge while conected to PC
Interresting?
You said you want to discharge your battery to almost 2%
Mayby interesting to read the story about Li-ion batteries.
http://www.batteryuniversity.com/index.htm
They say that's it isn't always good to discharge the Li-Ion battery totally.
besides:
Low Maintenance - no periodic discharge is needed; there is no memory.
Good Luck,

That's interesting
Thanks
this is totally wrong
you drain the ni/cd batteries for better performance not the cellularphones.
you drain the cellularphones battery ,potentially kill some battery cells.
drain it to 2% more than 15 times kills half of it capacity and/or age.
i am one of those anal people who likes to keep his battery in good condition by always letting it empty completely before recharging and i have noticed alot that i run into a situation where i need the phone fully charged for some reasion or another but dont have the time to sit around with all the nic's turned on waiting for it to die. i have seen a battery discharge feature on some devices that will rapidly drain the battery to 0 so it doesent develope memory when you plug it back in i was wondering if anyone has made one of these for the raphael?? any links would be apreciated.
i have already rtfw'ed and searched everyone seems so obsesed with prolonging battery life not draining it so i have had no luck
You are actually doing more damage to the battery draining it all the way then if you'd just charge it when you can if you are indeed doing this every single time.
All HTC devices use a Li-ion (Lithium Ion) battery, which do not get a charge memory in the cells like rechargeable batteries of yesteryear.
Instead their life cycle is based on number of discharges and recharges and the batteries age. If you're needlessly discharging your battery and recharging it, you are dramatically shortening it's life.
You should read up...
http://en.wikipedia.org/wiki/Lithium_ion#Advantages
...they may be irreversibly damaged if discharged below a certain voltage.

Like many rechargeable batteries, lithium-ion batteries should be charged early and often.

Lithium-ion batteries should not be frequently fully discharged and recharged ("deep-cycled"), but this may be necessary after about every 30th recharge to recalibrate any electronic charge monitor (e.g. a battery meter). This allows the monitoring electronics to more accurately estimate battery charge.

It is clearly stated in the Fuze manual that it is SUGGESTED that you fully discharge your battery and fully recharge to get the most out of it.
thanks for the advice i will look into it but i would still apreciate someone answering my origional question as to wether or not anyone has actually made one of these apps

This is almost certainly suggested so the battery meter maintains a good calibration. As GldRush points out, you are not doing any damage to the battery or shortening its life by short-cycling it. You could also harm it by deep-cycling it. Allowing the phone to go to 0% is not, however, deep-cycling the battery. For the phone, 0% is the point at which the operating voltage of the battery has dropped to a level that is approaching the lower limit for the board set (with a safety factor included). That's almost certainly nowhere near a discharge level that could damage the battery.
So if you want to let/make your phone go to 0% before every charge you are probably wasting your time (except for the slight benefit of frequent battery meter calibration), but also probably not harming the battery.
After the 2nd battery warning notification comes up, I end up just launching youtube and running a video. The use of 3g coupled with video playback gives me an auto shutdown of the unit with 5 mins or so.
Turn on the GPS. That should drain it in less than an hour.
I haven't seen any discharge apps but I do know that the biggest battery vampire is palringo...start palringo and join a group with a lot of members and your battery will drain at least 20% in about 10 minutes...even if there are no conversations going on you will still get a dramatic battery drain running palringo in the background
Haha, or use an older version of S2U That drains your battery like crazy too.
Way to discharge a full battery within an hour:
- Start Wifi and let it stay on (no need to connect).
- Start Bluetooth and keep it on (also no need to connect).
- Open Google maps and let it use GPS
- Put Google maps in the background and start playing Teeter.
it's almostly no necessary......

These batteries actually get hurt by completely discharging - you're not supposed to do that - you'll kill the battery by bringing it down to 0% too often..
(but to answer you - that's easy.. turn it on.. this phone's a battery hog..)
-m
There's an interesting artice in The Reg about lithium battery maintenance (albeit more related to netbook and laptop batteries).
http://www.reghardware.co.uk/2009/05/07/beginners_battery_maintenance/
not needed, but just run palringo and google maps while listening to music streamed from di.fm in Kinoma. (pretty much what I run day in and out )

this works for me
I changed the battery for a new one with 3400mAh capacity and of course android gauge reporting it wrongly. How do I patch kernel manually to change default values from manufacturer's 2300 to 3rd party 3400mAh? Any ideas?
Well, to reply to myself - I found it.
The solution to 'fix the gauge' with extended battery is to not let it drain to 0% but instead to drain only to the low battery indicator! I used 10% remaining indicator mark (didn't tried with 15% as suggested @batteryuniversity or 5% when battery saving mode switches on), then the crucial point is to switch the phone off and let it recharge in powered off mode till 100%. Repeat the procedure 2-3 times and it should be good.
The charging circuitry needs to learn what the max and min are, so it can then stretch its range to fit the battery's new and much larger capacity.
As a result now I have 3400mAh that holds around 3d6h with more than 8h of screen time. Hope that helps to someone too.
can u please tell in simple english !
