Ok strange thing here
I have 2 prophets with same set up
IPL 2.20.0001
SPL 2.20.0001
Radio rom 2.20.21
flashed with the same WM5 the prophet touch IX
dow to the strange thing
prophet 1 26.8Mb Memory ideal at 103mA after soft reset
prophet 2 25.8Mb Memory ideal at 86mA after soft reset
so battery drain is not only related to rom but also hardware and why does one have 1 mb more free memory?
this is just a strange opservation I made
both have the same cell operator ?
If not ... maybe GPRS or EDGE is available for one of them.
Or the date of manufacturing is different.
when you look at their battery consumption ,did both batteries had the same amount of charge ? charge both of them to 100% then soft reset, then wait for os dll to get unloaded .. ( wait for 1 min) then look at their battery consumption

Hi Gullum,
I think it is because of the hardware itself since the manufacture cannot make 100% hardware similiarity.
New hardware will better than old hardware, the operational time will effected to the performance. Just like you have 2 cars with the same manufacture but different production year, the new one will better than old one.
Even they produced in the same time, the hardware not 100% the same. may be only 95% similar.
Twins person not the same also but looks alike.
Because of this hardware, so everyone who is using the prophet will have different problem.
Cheers
Well this is good news for me but bad news for some
now I know that some problems are not software related always.
and then there is no way that I can make rom that has the same power useage on all phones.
the bad news is that if the battery useage is good for some and not for you there isn't much you can do about it

Just additional information for electronic hardware.
Every electronic part has own MTBF - Mean Time Before Failure, so if you use bluetooth frequently, the bluetooth hardware will fail faster than others part.
If you charge your electronic frequently, the battery will be broken sooner.
As i know PDA battery will last after you charge around 500-1000 times depend on the manufacture. Let say you charge the battery every 2 days, so the battery will last between 1000 - 2000 days.
So everybody will get different problem with their electronics because it depend on what they have done to their things.
Cheers
Did you test both after hard reset with SIM card off ? You should give it a try
But consumption differences can easily be explained by different mainboard & components revisions & firmwares..

Well, this is not really a problem. The problem is when the battery drains an additional 50/100mA over another prophet or other ROMs..
That is for sure a driver problem.
The really strange thing for me is that 1mo !!!
Where's it gone ?
For battery drain, i always get more than 1% per hour. Until one day, i removed all my today items(in fact only device lock) and left only home plugin. After a full charge, I experienced only 5% drop over the next 10hours. I was using Crystal V3 and radio rom 2.19.21. The battery drain is slightly more when tested with 2.69.21. I am quite sure it works since I have tested this method on both G3 (mine and my buddy's).
Another thing. While it is achievable, you must ensure Activesync is not running in the background. There was once instance the battery drained 14% within half an hour and I realised it was Activesync that run in the background. Strange it does not terminate itself when i pulled out the USB cable???
Anyway the above is based on my observation so you may give it a try. Hope it helps.

Yes it's a realy strange thing I tried to swap battery and checked then change sim cards but made no differance there is still the same battery and mb differance.
Hey would you test both of them in same config (same rom, HR, sim off & suspend timeout off) with spb benchmark or any other ? Could be interesting..
It's about 1h job (disable built-in applications tests, because they often fail) for main test, the best would be to test battery too but I suppose it will be too long for you.
DISCLAIMER - I am just putting this in here so that if anyone gets any funny ideas ... Whatever you read/use in this How-TO Post is at your own RISK. The aim of this post is to help others who had the same issues as me when they were abroad ... and were stuck without a mobile Running MGLDR 1.13 and DFT stock ROM (WP7) and a USB cable but no other chargers ... If the OS doesn't boot you WON'T manage to charge via USB UNLESS you follow this HOW TO GUIDE (it's the ONLY ALTERNATIVE YOU HAVE OTHER THAN BUYING A CRADLE CHARGER) ... it WORKS 100% but I am fed up of finnicky people emailing /posting / trying to play the "experts" on the matter when they know nothing about the matter
Dear all
After going through all sorts of Registry fixes which were momentary in nature. I decided to find a viable alternative which does in actual fact work with all current WP7 builds and all MGLDR's provided with a USB Storage option.
It has been said that the WP7 Software does not charge the battery to its full potential. I also incidentally ran into the problem of charging the mobile when the battery died. Primarily because the mobile loads ... restarts ... loads ... restarts and you keep on "praying" until the OS boots to get it charged.
Alternative fixes so far which worked for me were:
- Adding android to your SD Card ..booting in android and charging it in android mode
- Charging it in Cradle Charger
- Some people even pulled out 2 wires from a USB cable (+ve and -ve) to get their phone on again (crazy and dangerious)
- MGLDR 1.12 hangs when trying to charge mobile while it is off.
- MGLDR 1.13 reboots (as a momentary fix) in order to avoid the hanging caused in 1.12
Problem is
- I can't stand the fact that we have to have 2 OS'es to get it charged properly
- I can't stand the fact the we have to remove the battery in order to get it charged externally via cradle charger
So we have to adapt to the present circumstances unfortunately. If nothing, and the fix does not give you more battery life, this method avoids you from
- buying/carrying a cradle charger with you when abroad.
- having a dual boot system (WP7 / Android) on your phone
- making you do crazy/quick fixes such as the USB cable thingy mentioned above ... (don't try it)
no need for anything of that!
HOW TO:
So in a nutshell if you drained your battery too much and don't have a cradle charger ... with the added bonus that you may get improved battery life out of WP7 is the following.
- Boot into MGLDR setup menu (hold the end call button at start up)
- Boot your mobile and hold the "End Call button" to go into the MGLDR setup screen.
- Choose USB Storage menu
- METHOD A - Let the mobile Charge for 6 hours (typically overnight would be ideal) (Note: It will not over-charge and it will not damage your battery.
OR
- METHOD B - Charge the mobile for 4 hours (to keep mobile on overnight) and charge the last hour in usb-mass storage mode. This has the added benefit that you do not get your screen on for a long time. This will not damage your battery and those of you who are worried about over-charge can go for this alternative and not take any risks.
- NOTE that you will NOT get the charging indicator ON in this mode. PRECISELY that's the whole point of charging in this mode, the battery will charge to its fullest as it is not under the influence of the WP7 software. It is like as if you put the battery in a cradle charger and charged it outside.
- When you wake up ... hit the back button to go to main menu and choose RESET option to reboot your mobile : ) and voila!
RESULTS:
- I got improved battery life charging the mobile in this MODE. I got 36 hrs + of battery life (normal usage) which is very good.
ADDED BENEFIT: QUICKFIX FOR DEAD BATTERY - NO CRADLE CHARGER - NO DUAL BOOT
- There seems to be mixed feelings about this as some of the readers have reported no discenable difference in battery performance. While I will not contradict these people, I got improved longevity from the HD2's battery. Clearly the OS is reporting the battery level badly. If NOTHING this method still serves as a quick fix
- if you drained your battery and cannot get your HD2 on again
AND
- You Do not own a cradle charger
- Registry did not work for me.
SETTINGS - WHICH IMPROVE BATTERY LIFE:
- You can optimise settings as follows in order to get my same results, again I hear many of you not wanting this as it turns of features from their PDA but as I said above, we have to adapt for the time being:
Settings are -
- ROM DFT Stock ROM original build (issued 13/01/2011)
- Radio 2.15
- Screen timeout 30 seconds
- Screen brightness set to auto
- Wifi turned off (on only when needed)
- Bluetooth turned off (on only when needed)
- Location turned off (on only when needed)
- Data Connection turned off (on only when needing to check mail)
- Email sync turned off (not every 30 mins)
- 3g turned ON - UPDATED - I got better battery life with 3G ON but this may change from country to country so I suggest that you have a go with 3G being ON or OFF and see which is better for you....)
IF YOU USE THIS POST - HIT THE THANKS BUTTON - IT's the LEAST you could do!

Hi Alcatrazx,
sounds logical I´ll give it a try and report later, thanks.

Thx
Thx Bro!
Will try it later too. I'll report.
One question though... Do you need to do this everytime you charge your phone, or just the first charge?
Sounds interesting, I will try and report

Sounds like you have to do everytime... If you reboot your WP7, the battery is under the influence of the software again and does not charge correctly. Beat me if I'm wrong
Very interesting. I will try it
It's a good idea for some times, but I would not use it as an every night thing.
I sometimes get calls or messages during the night (and usually they are important). Another thing is that if you use your phone to wake you up this will not work at all.
I hope WP7 development progresses and solves this issue in the upcoming updates.
Nevertheless it's a nice way of going by, and thanks for taking the time to test it and post about it.
PS: does the light turn green after 6hours of charging or not. Probably not, but worth asking .
Another solution should be to charge a second battery in an external charger...
pronor
Another issue with this "workaround" is that MAGLDR keeps the screen opened, which can cause some devices to overheat, so be cautious with this one. I say that an external charger is the smartest alternative. I actually use this method and it works perfectly.

Sorry to sound pessimistic, BUT, people have already reported clearly in other Threads that they have tried the solution of charging their battery using an external charger with no luck. I can't see how this is any different. In addition, 6 hours will probably kill your battery in the long run (overcharging) - I have queried HTC support about it in the past.
Simple enough mate! Though 6 hours of battery charging will probably make significant damage to your HD2 battery... HD2 normally will charge in about 1 and a half hour or 2 udner WM6.5 or Android!
Not bad idea though! Bravo..
Charging while in Android remains for me the most convenient option. I must say though that this battery issue in wp7 is not that obvious for me. The phone charges quite well in wp7 and only sometimes I feel the need for a restart, after which the percentage increases with 15, not more.
most chargers since the beginning of time have a battery cut off, when the charger unit detects the polarity is starting to reverse it switches off, of course i cant say for sure using the MAGLDR method would use this, potentially it could just be a case of "connecting two wires to a battery" which as you guys have pointed out would not been good, at worst your battery could get seriously hot, or potentially if you reverse the battery polarity enough you would have half of a battery thats unusable.
I think what should be taken from this however, is that like myself and other have been saying for a long time, if your battery is charged propperly it will last a long longer, people reporting empty batteries within 20 odd hours, in my opinion, either have dud batteries or are not charging them properly
the MAJOR plus side to this post is the ability to fix the empty battery restart issue, that alone makes this idea a gold star and should be stickied!

People reporting these batteries issues my friend are people who are knowledgable enough to reach to xda-developers forums - i.e. people who have a pretty good understanding of what battery drainage is and whether their batteries are dying or not; who have installed a number of winmo roms, android roms etc.
there are roms that drain battery and others that handle power better. in the ports of Windows Phone 7 for HTC HD2 there is an issue with battery drainage, and thats a fact.
There is no issue with bat drainage but with false bat stat reporting.

your level of wit and sarcasm is actually quite funny given that you completely got my point wrong, the issue is quite simply this, the drivers for our HD2 are copies from another device, a device that is similar but not the same, the issues we have with battery are down to the fact that WE do not know if the battery is charged or not, at least at a first glance, and given the inability of many people on here to actually read threads and posts correctly it is not beyond the realm of possibility that many users dont know what level there battery is charged to, thus it may not be charged propperly.
If windows reports a full battery and its only half full then it will "appear" to empty twice as quick, now i think thats pretty clear for every one?

we cant
our phone must be different to a degree than the phone this ROM is based off otherwise we wouldnt have the issue, lets all assume for a second we can actually start chopping and changing files in WP7 like WM. We would need to find some sort of driver that exactly matches our HD2 and i doubt that will happen.
whoever made the driver isnt going to just bring out a new version for an old peice of hardware that isnt supported by MS, perhaps if a new piece of hardware has the same battery controller as us something can be done.....maybe

You have the following options:
1. Try the registry tweak. That worked for me and I actually have no battery issues for the last 2 weeks or so.
2. Charge the battery under Android during the night. That's pretty usable as you only need to reboot and you still have a fully functional phone Way better IMO than the USB Mass Storage trick.
I have a minimal Android installation on my SD (Angry Birds, you know) and it currently reports roughly the same values as WP7.
So, I have had a serious battery drainage problem, like most of hd2 users with wp7.
My battery usualy run max. 24h!
Now my phone run 2-3 days without charging.
I have just turned off connection with xbox live
So, go to the settings -> applications -> games, and turn off "Connect to Xbox Live"
I have 3G off
Data connection on (but mailbox, shares, weather ect. is updated manualy)
I hope this will help you...
Interesting will give it a go..... I have to say I beleive this and other 'solutions' may be solving part of the sympton and not the root cause BUT if it helps that's always good news until the chefs can get to the bottom of it!!
Thanks will let you know.
Cool cool
I already did this now.
Will also check it, and provide feedback.
Battery life is a bit of a problem, but atleast i have a car charger
I will give it a try.
3G on
Data connection on
its work this solution ?
I think it should work. I checked battery dainage with Xbox on right after turning phone on after sleep - about - 42 mA. So without use of the phone max time is less than 30 hours. But if Xbox is OFF current is just 5-7 mA. Means 6 times less on stanby!!! Will give it real timing try. Used Battery tool to measure current.
hello
did not work for me
It doesn't work in real life. After start some apps and close it current returned to 42 ma forever.No more 5-7 ma. Only turning on Airplane mode gives 2-3ma standby. So all bad battery life comes somehow from radio is too active.
Hello all.
I hear that if u change the radio version to a down one you have more battary life ..is it true ? there is anyone that tried that?

From my experience (only 3 days rooted LOL) you have to find radio that works best with your carrier. Better reception will stop phone trying to find masts, hence improving battery.
Sent from my HTC Desire using XDA App
I don't see any problem with battery draining. If it gets you over the day, what do you need more. Over night you plug it in.
I have all switched on (location too) and no problem with music maybe 1h, reading mails, checking facebook several times surfing internet and news. I would even say its better than WM 6.5 doing the same, at least the same.
I think battery draining is not hd2 problem wp7 is the problem
the real solution for batery is - turn on 3G
try
batery life is 2 days with many calls, play and others.
22.03 - 10:00 am - charget
24.03 - 12:00 pm - charget agaen 50 hours
this is experience of one my friend and works,
I didnt try becouse I wait new rom

It is definitely problem, comparing with all android ports where battery life is x2 more longer than in this "simplified" WP7!! Battery is dead in a half day in a standby is normal for you?
I solved my battery calibration issue by installing HTC battery tool, it fixes the calibration of battery so correct full charge is 100% and correct no charge is 0%. Give this a try, I am sorry I cannot post the link but I found this app on XDA too.

ok im running HD2O_1.04_DFT_LEO70_RELEASE and WAS running radio 2.15 and after 3 days testing and very poor batter life with registry fix, i decided to change my radio to 2.12. and so far after 7 hrs of testing ( full data, 3G, and internet browsing + youtube here andhier) my battery is still 3/4 change the radio it take 2 sec. to do.
with the old radio i was using, i went to work at 6a.m. got off at 3p.m. and i only had 1/4 left. with radio 2.12 i still have 3/4 and i used it more because im no longer at work.
try it good luck it worked for me
i will post another update around 6p.m. pst.
HI GUYS
IM USING RADIO 2.15.10
AND HSPL 2.08 ,
MY BATERY DRAIN VERY QUICKLY , I HAVE ALL SETTINGS OFF , 3G OFF. WHAT I DO WRONG or what i need to to to corrrect this issue.?
anyone are having the same prob??
tnks to all
there are at least 2 threads on the first page about this...
check the first post here http://forum.xda-developers.com/showthread.php?t=1041912
i read in one of the threads that we should charge the battery in magldr usb mass-storage mode for about 6 hours, and that worked brilliantly for me...
gave me about 40 hours of battery...! (3g on / data/wifi off - data/wifi on when needed)
i try use that mode but the charger light dont show ON , is not charging , i try using the charger directly to ac power and cable directly to pc mode but nothing he didnt charge .
Radio 2.15 seem to drain battery too much (from my own experience).
You can try old radio and see if battery life is getting any better (I recommend 2.12 & 2.14)
omg my phone only hold on 11h today with low usage, i dont know how to make him stay more time alive , the raDIO 2.15 I DONT THINK is the problem because many users are using 2.15 and dont say any... any sugestion??? if i cant fix the prob i need go back to andoroid or 6.5 version

Try to use HD20 1.12 and do video trick - with low(if it's realy low) usage it will easely survive 2-3 days.
i confirmed last night that the charge trick in magldr in usb storage does work to charge the battery.
I found that when my phone starts to get lower on battery that a reboot gives me more power due to the power meter being out.
Also a charge in an external charger helps.
sorry im trying to understand how can users see the MA off batery in battry tools , im trying to use the trick of change the camera mode to video mod and leave , they say the batery consume go to very low usage , like they say here but i cant find the "MA" in battery tools to compare .
this is what they say to do
"i start camera with green button and then switch to video mode there, wait for autofocus and after that just simple go out to main screen by pressing windows(middle) or back button then stanby current drops to 5-6 ma from regular 40-42 ma. (Switching to video is important - if not switched no results found)
It stays 5-6 ma on standby until next reboot. If i reboot and don't do this camera play current is 40-42 ma. But if i start camera -> switch to video -> out - current 5-6 ma.
After hack applied I used phone in different ways - talk internet email - standby still low 5-6 ma. I gave it 12 hours try - lost only about 12-13 % of charge. Checked battery outside of phone with load - real lose of charge was about same as Battery tool shows. Will continue to test longer but can expect at least few days with some usage of phone.
Did the same trick with my friend's phone - same results. It looks like really a bug some where.
Please report your results and HD2 type.
Was on XBmod 1.04, 12 radio, location on, data on, bluetooth on, xbox off, wifi off.
If this problem really exist it will be found in all ROMs.
P.S. Tested phone before with most others ROMs - found this one is the best, thanks for this ROM.
Hope this will be fixed permanently in NODO."

Yes you are right it is not show ma. Electrical current is measured in Ampers or MiliAmpers. So look for Battery Current minus when on battery, nothing(plus) when on charge. Do video trick send phone to sleep mait few minutes, then wake up and fast go to battery tool wait there - you will see. Most important is ROM type. They should be all same, but a lot of testing shows they are not the same(not big difference, but exist in standby consumption).
Want to add - if used proper ROM and this trick you won't need any external charger, because i doesn't give much(internaly battery charged very well - i did a lot of external experiments with battery charged in phone), no need to go any magldr because not help much and dengerous for battery. if you use pfone a lot you may need only charged(in or out) spare battery because it works continiously only 3-5 hours.

I'll try to play with camera modules this WE since they seems the same between HD2 and HD7. But like I've said the bug is certainly due to the flash driver or a dependency with the camera driver or pdd/mdd.
For the rest (Wi-Fi apart) there is a lot of differencies between users with the same rom. Tmous/HD2, revision number of the device, OP/ coutry (for gsm band) etc. all this count to what radio we use (HD2 and HD7 extracted) and some drivers may be not acurated.
The RIL parameters for your OP are important too beside the radio because how your phone reach the GSM network has an important impact on battery consumption.
There is a tool I dindn't know exist before and testing now which I like: WP BENCH.

For the rest (Wi-Fi apart) there is a lot of differencies between users with the same rom. Tmous/HD2, revision number of the device, OP/ coutry (for gsm band) etc. all this count to what radio we use (HD2 and HD7 extracted) and some drivers may be not acurated.
The RIL parameters for your OP are important too beside the radio because how your phone reach the GSM network has an important impact on battery consumption.
There is a tool I dindn't know exist before and testing now which I like: WP BENCH.

Yes you are absolutly right - a lot of unknown things and differencies. It would be very good if you will be able to look closer at all this. I don't have tool, enough knowledge and actualy much time to do that. Thank you very much for your work and results!!!!!
Yes, it's true. It worked with the camera bug... Normally my battery would be empty. But now I only used a quarter of my battery life. Nice !!
Hello, guys. I know this post is awfully long, but please, bear with me
I am fairly new to Sammy, as I just got the S2 (I9100, not some other variant... it's the very original) three days ago. I rooted it, flashed CWM, and already tried a few ROMs. I'm sticking to MIUIv4 (WIUI, actually) for the moment, as I loved having MIUI on my previous devices.
There's just one thing that makes me wanna throw rocks at this phone... and that's not the Super AMOLED+ screen that has stains / ghosting effect... it's the CHARGER.
I believe the charger I'm using is original - it was in the package, so... it can't be a copy, lol. It says it can output 700mA at 5V, which is pretty standard... but it seems like it just doesn't do its job!!!
I've had three HTC devices before, and the HTC charger is just a brick that you plug into the socket, and then plug a USB cable in it (just like Motorola's and Apple's recently). It outputs 1A at 5V.
The Motorola ATRIX I previously owned had a charger that was outputting 850mA at 5.1V. Charging that 1900 mAh beast battery would take just a little over 3 hours!
I no longer own the ATRIX (sold it to get the S2, actually), but I did borrow a HTC charger (with a HTC USB cable) to see if I could charge my S2 faster. Nopes. The charger barely gave the S2 0.5 amps... which is normal, since I hear two pins must be connected in order for the Samsung phone to draw maximum power.
My Galaxy S2 is charging painfully slow with this original charger. I installed Battery Monitor Widget and let it log the battery charging overnight - the log file is attached below this post.
At the very first line of that text file, you can see the charging began. I let the phone turned on, with the screen off, to charge overnight. Wi-Fi, Mobile Data, BT, GPS, Auto-sync was off. It was just in auto 2G/3G mode. That hardly matters!
It looks like the phone is drawing 641mA constantly. It doesn't top 700mA, but that's okay - neither did the HTC phones reach more than 900mA, when the charger was able of 1A output.
It took the SGS2 exactly two hours and 50 minutes to fully charge. Given the fact that the charger outputs 700mA, and the battery is 1650mA, I'd say that's right. A 1900mAh battery was completely charged in 3 hours and something, with a 850mA output charger.
Still, that's painfully slow. I had the HTC EVO 3D, which has a 1730mAh battery. Charging that (@1A) would take little over two and a half hours. I could even browse the web via Wi-Fi or do something else on the phone and the battery would still be completely charged in less than three hours (unless I play a game on 3G with max brightness on, of course).
Also, when the battery was at 1% at lunchtime, I plugged in the charger. I continued to send text messages and browse the web via Wi-Fi (screen brightness was on minimum). The battery level did not rise from 1% even after 5 minutes! You can see that in the battery log. Yes, the phone's battery was almost dead in less than three hours.
Oh, also, the first day I got the phone, after I finished rooting and flashing MIUI and everything... I was playing Dark Legends, over Wi-Fi (screen was at lowest, again). Battery got down to 6%, I plug it into the charger. Ten minutes later, battery was down to 2% ! ! ! So, the charger cannot keep up !
I did my homeworks and did a "bit" of Google searching... it turns out the charger is just as it is. But this is just ridiculous.
-----
I remember seeing something on Twitter several months ago... an article regarding an app that would let you adjust how much power the Galaxy S2 can draw from the charger it's connected to, simply by dragging around a slider. I'm not wrong, I DID see such an article - I just can't find it anymore!
Anyone... any suggestions, please?
Also, please note that I am in Europe, Romania, so I can't just go to a shop and find the most awesome charger that outputs 2A for $5 like you guys can (there, in the US)... It's not really at hand for me, lol.
So, conclusion is the phone can consume more amps during usage than the stock charger can supply.
Either reduce the power usage (lower brightness, disable WiFi/BT) when you're using the phone during charging or get a more powerful charger (although I remember the latest stock ICS kernels don't like charging at a higher voltage than the stock charger supplies, so you'll probably have to install a different kernel which doesn't have this limitation).
Oh, and please stop the non-sense about being in Romania and not having options to buy, the market's full of all kinds of chargers. Get out of the house and search, "lol".
This is not uncommon.
In fact, with my PREVIOUS phone, the SE Mini Pro (the original one), it was actually possible to drain the battery till the phone shut down, even on it's original charger.
With some modified power settings, mostly in CPU voltages, it is quite possible to have the SII charge properly even while in use, but bear in mind, it will take longer to charge if you are using it.

Playing Dark Legends, via 3G this time (so the power consumption would be higher, right?), screen at FULL BRIGHTNESS, Bluetooth and GPS activated. Battery Monitor Widget tells me the current being drawn is 641mA. Looks like the phone draws 641mA when charging, ~80% of the time.
The only problem seems to be when the battery level is LOW. Then, no matter what you do, the power level just doesn't rise.
With HTC / Motorola, the power draw was maximum when the battery was at its (almost) lowest level, and would decrease as the battery was filling. With the SGS2, it looks like it draws 640mA from 0% to 70%, THEN it begins to slow down.

Oh, but trust me, I have. You know, in our country, even cheap Chinese copies are over-rated. It's hard to find stuff like what they have in the US .
I've seen some sort of a digital charger, so-to-say, which would allow you to set the amperage and voltage that was being outputted. It was able of throwing out anything from .5 to 2 amps, at 3.7 - 5.5V (given your choice). Guess what : friend got it from the States...
You don't see such stuff here, in Romania.
Oh well...

On the HTC EVO 3D and Motorola ATRIX, it was yet to be proven whether undervolting the CPU would increase battery life or not. Undervolting as much as 200mV only reduced the ammount of heat that was generated (especially during gaming sessions). Although current = heat... the power consumption didn't seem to change a bit!
I even tried to downclock the CPU to 400 MHz - power draw would still not be sufficient in order for the phone to charge (when the battery level was under 10%). Everything was turned off, light on lowest, CPU pretty low... still going down, lol.
I have also experienced this in the past.... which was rather annoying if I must say however, recently I haven't had this issue, although it still charges quite slowly, it's slightly faster than before. I noticed this difference after I decreased the voltage from the cpu in each step, yes my phone is heavy undervolted thanks to magic config, might want to check that out, but it's still as smooth as ever without a hint of lag props to the hyperdroid team...they are the best in my opinion, I use their rom since the hd2 days recommend their rom to all galaxy s2 users.
Anyway, my point is, I can have my screen in full brightness and still use the phone as is when off charge and it will continue to charge. Also, battery life isn't an issue for me anymore after undervolting, I can live with 15 hours battery life under extreme heavy usage with full screen brightness of 4-5 or more hours of screen on time....and that's with 1650mah battery. I plan to get an official 2000mah battery which will increase it's life more

That's... impressive.
I'm using MIUIv4 (WIUI) wth Siyah v3.2.6.3 kernel. For some reason, if I undervolt even -50mV, the phone freezes :/

That's.... weird. I thought siyah kernal was more undervolt friendly :/ besides, I read somewhere that not every galaxy s2 can handle undervolting whilst some can. Rather, it could be the kernal too, I use the redpill kernal provided from the hyperdroid team, it's not the best in benchmark wise but what the heck... it doesn't stop to lag, it's extremely fast and responsive, great battery life, undervolt support for further improvements... you won't even notice any slowness compared to high benchmark devices. Red pill kernal is well optimised. I use noop scheduler and conservative governor, it's amazing how redpill handles this. Try it some time. Could solve your problem.

Just like your 48x CD burner doesn't write at 48x from start to finish, that's how the charging current is not constant; it depends on the remaining capacity, charging algorithms, etc. You're using a special case and asking too much, the solution has been given already (powerful charger and modified kernel to allow a higher charging current and voltage).

Yes you do. I got a 1A Energizer charger which really gives 1A for less than 10$. The variable supply you're describing can be found in any proper electronics shop, try "Maica Domnului" street

Yeah, I know that. That's exactly what I'm saying. The algorithm is different on the S2, it seems.
On all HTC devices I had, the current draw was at its highest (~900mA) when the battery was near depletion, and as the battery was filling up, the current draw was slowly decreasing. On the S2, it looks like it's the other way around. When the battery is nearly empty (1%), barely 100mA are being drawn. As it fills up, near 10% or so, the current draw remains steady at ~641mA, and decreases only past the 70% point.
Good thing is, the current draw remains steady at 641mA, no matter how much I stress the phone! That's astonishing - the other day, the battery was LEAKING 600mA instead of GETTING 641mA when the simplest tasks were done (no stress, that is), during charging...
Guess the guy who had this phone before me didn't really ever charge up the battery properly He said he had an iPhone charger back at home; I told him "nevermind, keep it".

The benchmarks are simply amazing; even with the CPU downclocked to 800 MHz...
I'll look for that kernel, hope it's MIUIv4-compatible. Thank you!

Everyone's talking about a specific shop down that street... and I never got to actually go there. Guess I gotta look for it... Was kind of doubting it was much of a big deal.
