Hi,
I've got an idea to "fix" battery drain in WP7, as well as with Android.
I can't really assure you how much it's working as I do this each time I install WP7 since the first version of MAGLDR is out.
I started doing this because I had battery problems with magldr.
Here is the trick : In fact, when you install MAGLDR, Windows Phone 7 / Android, or even update WP7, the battery is not charging but draining (that kind of procedure eats a lot of power). But even if the installation ends with a 40% charge, the OS will be sure, at first start that it's almost 100% charged.
I think it's a reason why the battery goes empty faster than with Windows Mobile. It was default OS, with default configuration etc. so 100% was 100%.
So I think we must, at least once, charge the battery outside of the phone, with a dedicated charger. In that way, when WP7 will start, it will see the fully charged battery (100%, for real).
I think the OS will know, when the battery will be discharged, the real capacity from 100 to 0.
I hope it will help, and that I'm not wrong as I don't experience any real battery drain if I do this + camera trick since first version of WP7, and with any Android rom (except MIUI).
Hi
My solution is close to yours.
After each flash I let drop my battery until the phone died and you can't restart it under WP7
next I start to charge it under MARGL 5 min then i start WP7 and let it charge.
Now i'm sure that the phone have a good battery calibration.
My HD2, 2 years old, and with camera trick can stay 48 hours in 3G but only 24 hours in 2G??? WTF?
You're not completely right here, OS would not think that change at first boot is 100% charge, you can easily check that by booting first time on half empty battery and indicator will show about 50%.
But yes, battery stats might affect battery drain, so there is a button in MAGLDR something like "Clear battery stats", reboot to MAGLDR, charge to 100%, click that button, boot back to your OS.
intresting therys
What is we charged up to 100% and did a hard reset would that make the probum go away?

Oh ok. Weird, each time I flash WP7 or Android, it tells me that I've got something between a 100% and a 90% charge, which isn't possible, after having installed MAGLDR, then flashed the new OS and waited for the first boot (really long with Android).
Nonethless, I flashed WP 7.5 with radio 5.66, and I'm experiencing a huge battery drain, even with camera trick & external charge.
Even Miui seems to last longer. And Android tells me that I have a 62% battery charge, and I restarted the phone on WP and it tells me that I still have a 76% battery charge.
Why don't I have the same charge estimation ?

well I can't answer that question but I would bet android is not the 1 that is giving wrong charge estamations in on bttfv2 and I was on v1 and never experienced fast battery drain I personally like the wp7.5 over the other os's so I'm dealing with the fast battery drain issue & random reboots as well I also think the to problems are related some how the random Reboots it never happens when on on a charger! I really think someone should go back to bttfv1 to test and figure out what went wrong when new registry edits was implemented or the new rom was cooked but anyway I read DFT is also working on a new rom I'm not sure if it will be for hd2 tho.
I'm really hoping the problem can be sorted on my last phone I got about 300hrs out of 1 charge but charging touck a wile on my hd2 charging seams to be pretty quick which might not be a good thing not sure. But last night I had it on charge almost 10 hrs after it was already 100% and when I finly got it off the chager it seamed to last a little bit longer
But on rough estimate I'm thinking it last 5 hrs witch is just horrible

Unfortunately, it's a mistake. I've never seen any "clear battery stats" menu in MAGLDR. But I think it exists on ClockWork.
It's a shame...
Battery life 24hrs+
All,
After reading the above posts, I started practicing the following;
* Let battery drain more than 90% or until critical battery warning appear
* Charge in full
* Power of phone. As the phone power off, power off charger ( ... this action may be insignificant)
* Boot the phone to MAGLDR
* Select "Reset" option from the menu
* Phone reboots normally
I have been doing this for the last 2 weeks I guess plus more than 8 charge cycles and now my HTC HD2 lasts 24hrs+ at any rate.
... I am not a heavy user, but still, I have OutLook, GMail, FB, Twitter running 15mins sync interval. 10+ calls + 5/6 SMSs a day in average. My good'ol battery keeps me happy.
... hope this helps someone ...
I found that it was my choice in SD cards that was causing battery drain. The camera trick got me down to a battery draing of -200. I couldn't understand why I couldn't get down to -7. WP7 "seemed" to be performing fine.
Switched to PNY 16GB class 4 and I think WP7 has accepted it. Have had a few reboots, but nothing I can pin on the card yet. My battery life is amazing in comparison to before. W/ wifi and bluetooth turned off, I get a battery drain between -4 and -7. MUCH better than before.
I can't get Battery Tool to work to check the drainage on Mango, but I found out that having 3G enabled, Push enabled (set mail check on "upon arrival") is giving me the best battery life. I'm using Mango since yesterday morning 11 am until now (it's 9.42 here) and I have 31% battery left.
Average usage (but it's enough for me) with internet, mail sync, twitter, facebook and some pictures.
for the record, I did not use the 'camera' trick at all.
When I disable push, and have email check set to 'manual' i'm starting to have drains and I have to use the camera trick to keep it low...
I know everybody has different results.. but I just wanted to share this, see if others can relate to this
Its pretty strange this battery drain issue, i struggled with it for months with the last wp7 rom i used.
With this rom i struggled with sd card issues like everyone else, in the end i'd bricked 4 cards of differing sizes and the onlycard i had left was the tiny 2gb sandisk that came with my HD2.
Since settling on that card i've had no issues other than storage space and battery drain is a thing of the past which could suggest that card compatability is at the heart of the problem.
Its my guess that constant attempts at read/write failure may be going unreported by wp7.
Currently im seeing about 36hrs at my regular usage, i can stretch it to 48hrs if im careful.
My wifi is on throughout my working day, i make on average 6-7 calls and send and receive 10 or more txts along with a steady stream of people hub updates.
I'm happy in the belief that i don't have a battery issue, i just wish i had more space.
So much for my optimistic post earlier, one reboot messed up the battery read. 40% left and 2 hours of usage .... I give up
Sent from my HD2 using XDA Windows Phone 7 App
... try this for a change

... sometime back I too had the same problem, but that all changed!
if you fully charge (100%)..your phone in wp7 , it will show erroneous battery drain,...you can rectify it by restarting the phone, then use the camera trick.
if you charge till 99%.it is ok, but 100%...you need to restart

I haven't had that experience. Sometimes WP7 won't allow a full charge to happen though.
Something weird just happened.I was having Bluetooth problems.It wouldnt turn on.I then Flashed the DEv wifi plus Eu fix cab.It fixed my bluetooth but with some added treats.My battery life has more than doubled.Used to go less than 8hrs of normal use but now i hv gone 17hrs and i have around 50 % left.I didnt do any camera trick.Has anybody experienced this?
Hi, could anyone give me the link to Battery tool for WP7 Mango. Thank

Hi,
Just ask for any other information, I'm bound to not remember to provide everything Have had this i9100 for about 30 months. No battery issues for the first two years but plenty in the past six months.
Phone would switch off suddenly (no low battery warnings) or go black / unresponsive and super-hot. Replaced the battery and after about 2 months the new battery (probably not original) was literally bent and mis-shapen. Bought a genuine (I hope) Samsung battery and installed CyanogenMod and still seeing hard power-offs when they wouldn't be expected.
See attached for this morning. Phone unplugged after charging (via USB) all night. Attempted to use Apollo and it wouldn't work so didn't even use the phone on the bus. Clearing data for Apollo after arriving at office and that is working again now. Made one long phone call before starting work and towards the end of that phone call just dropped. When arrived into the office plugged back into USB again.
Why did it power off at 70% and why wouldn't it turn on again even though after being plugged in and charged for 5 minutes it starts up at 40%?
What do you think? Is this a hardware issue and I have to give up on the phone
Does near camera get hot ? it shows media taking 21% which I assume it is not normal .
also we need to know about Rom version and recovery version .
Media scanner is the process that scans every folder and file so that if you copied or downloaded a .mp3 file it shows on your library . However for many reasons this can go wrong . Do you have folders with many files ? (talking in thousands) ... for example apps like maverick can download many thousand mapTiles that saves on internalSD or ex ... Then MediaScanner everytime needs to go trough all those many thousand files and that burns cpu/battery ...
if so try http://geeknizer.com/fix-android-media-server-scanner-sdcard-cpu-battery-drain/
other than that battery can go bad which is easily replaceable .
Attached screenshot from this morning. Notice how it drops to zero at a point. The phone switches off even though the battery isn't exhausted.
Near camera not getting hot. Not sure whether media 21% was normal or not, that morning only 30%+ of battery used when the hard switch-off event happened.
ROM is CyanogenMod 10.1.3-i9100 (Sept 23rd) and recovery is CWM v6.0.3.6
No folders with many files. Use the phone lightly really. A few MP3s, email, phone calls, general browsing, occasionally Skype.
Real question is why the drop from almost 70% battery to zero, as shown on last weeks and this mornings screenshots?
Battery is brand new, unlikely to be the problem.
Will install a battery drain app and study closer.

The most advanced app I can think of is battery monitor widget pro which can show you energy flow in mA per ( by default every 10min ) . A stock i9100 has a 1650 mA .However I don't think it can explain dropping in energy like that . No battery saving app will resolve this issue . There are some battery calibration apps around . I don't know what they exactly do ...
I have an i9100 . There has been some " Episodes " when I shut down , remove the battery and re-enter , turn on and see unexpected drops in the juice but the most extreme was dropping from 38 to 15 . Never when running android .
When phone gets superhot for not reason it sure is using alot amount of battery . I would suggest a factory reset or changing rom/recovery .
Plus I would like to know do you experience a crash ( after going dark you simply turn on the device again ) or drain battery ( which your device wont turn on until its in charge for a few seconds/minutes ) .
If everything fails I would be suspicious about mainboard .
----------------------------
On a second Look I suspect the gap you are seeing in the battery is a state when you experience a crash which loads the cpu that uses juice enough that android is running to record the gap but not functional enough to respond which result in something like the image above . I don't believe the battery can go from 70 to 0 then when you connect to a charging point you gain 50-ish % battery in a jiffie . When I think back I can say I had battery stats like that and my phone still is without issues ...
It's not getting super-hot any more. I think that was down to an old battery. What confused matters somewhat was it still got super-hot with the replacement (non-genuine) battery, which after a month or two was actually buckled out of shape. The phone was running Samsung ROM then.
Since then, have installed CyanogenMod and genuine Samsung battery and it's better behaved in general. Just these occasional crashes or whatever they are.
When it goes black, it won't turn on again, until after the phone is plugged in for a minute or two. Then it will turn on and report much higher than zero battery. It could still be some kind of looping crash where the screen is black but Android is still running. That wouldn't explain why it recovers when plugged back in though.
Since these issues are across 3 different batteries and 2 different ROMs, I'm tending to suspect that mainboard myself. And I don't trust any of the high-street phone repair places. They have two options for me: (1) sell me knock-off batteries, (2) replace mainboard.
The phone is still functional to an extent, it's just I can't rely on it. It's good for a half-day, after that I can out and about uncontactable and unable to take a snap photo or whatever on demand. Annoying!

it seems that samsung firmware is becoming worse and worse. I have a 75000mAh extended battery and it would last me about 3 days with the MK software. i updated to the NC5 one, and batteyr life took a dump at most a day with the same usage. I dont even dare to put the original battery as it lasts me 5 hours. I though it was the battery so i replaced it, but same thing. I am now on NG6 and not much improvment. Besides the screen, ANDROID SYSTEM and ANDROID OS are using the most battery resources. WTF are these damn things? what is the difference between SYSTEM and OS. To me they should be the same. Has anyone noticed this, or is there something that I can do to improve it? thanks.
If you select them, they will display what is included in those packages.
Android System and Android OS are NOT the same. Not at all.
since my last full battery recharge, android os has used 64% of my battery, screen 9% android system 7%. this is ridiculous that the OS is using that much battery. forget about what people are saying that screen consume the battery is the damn android or whatever verizon is putting into it

That is not normal...sounds like you have some type of wake lock or some background app that isn't shutting off. I cant remember off the top of my head but I think theres an app called better battery stats or somethung like that and it hwlps you track down what specifically is draing you battery...as in what specific part of the android os.
usually a reboot will fix these issues, however if that fails then I would look Into the better battery stats...and then a full factory reset/or odin if possible
Too bad that those apps require root to work in kitkat due to google's change in permissions. This sucks.

I had the same issue. My battery used to last me about 17 hours (two work shifts). After some updates it would be at about 5% after an 8 hours shift. I replaced the battery thinking it would help but it made no difference. I finally got fed up enough and installed Safestrap and the Hyperdrive Rom. The difference is night and day. After one shift my battery has been 50% - %70 depending on my usage. Not being familiar with Safestrap it took a little work, but it was well worth it.
As indicated above, most battery life issues are caused by apps failing to allow the phone to sleep properly.
Get better battery stats, root your phone, and allow it to run for a at least half a day. Wake lock detector works well too, also requires root.
Google location services is a big culprit of background activity.
Tracking down the actual causes takes time, lots of it.

I got replacement phone with NG6 already on it. The battery life sucks. For some reason when it goes sleep, sometimes the battery will go up a 1 or 2% , have No idea how it's doing it
hi guys,
I have an Lg G5se (H840) and after the last update I noticed something strange with my battery stats; i.e. it happens that doing the same tasks for an hour sometimes it dicharges very rapidly and sometimes, for the same task, the line stays flat and it never drops a 1%.
What do you think the problem might be?
What could I do?
In the attached screenshot you can view an example of what I'm saying: be adviced that I keep doing the same stuff again and again (ten minute of a YT video, rendering the same pages of the same site etc etc)

Its hard to tell without the usage at that time too
I do agree that that is a pretty hard drop in batt very short time
Next time it does it also post screen shots of whats using the battery also and we can go from there....
ok: next time I'll post the whole list.
In the mean time I made a factory reset and restored the backup with of bridge.
it's hard to tell if the battery controller sits inside the battery or in the chassis's (in the first case I'd just swap a new battery).
the thing that concerns me is that this strange behavior started after the last ota but it could be a coincidence.
by the way after the reset the phone feels a little bit snappier.
I'll keep you updated in the next few days.

The third is newer, Actually will only get 2 to 2.5 Also have noticed the "good" never charge in the cradle to 100% when I put them in my G5 they start at 1 98% and the other at 96% but lasts longer through the day than the 3rd batt that is newer and does charge 100%

I run my batteries down to about 30 % and swap out and I go through 2 batteries a day
[A quick update]
I made a factory reset & I pulled out and reinserted the battery (the same) in (and removed a little bit of dust inside the phone).
Now then drain is the same as it used to be and the slope of the curve is regular.
it's so sad there is not so much enthusiasm for this phone: I've just read about a fingerprint reparation on this forum that was very easy but I know, LG is a b**ch.
I'm getting an appalling battery life on my S9+
The device is a European version with the Exynos CPU, non-rooted (and i don't wish to do so as i do like using the Samsung security features that the device offers)
I've attached a screen grab which was taken right after waking up in the morning. During the night (around 7 hours of sleep) i've lost 14 percent from when i put it away
Any suggestions? I'm really in a loss for what to do other than rooting and modding
PS: Suggestions of the sort like: Turn off AOD or Turn off Sync or Turn off Mobile Data aren't really helpful. I know that these drain battery but the device has these features for a reason and the battery was mostly fine when i purchased it with them on.

I know you didn't want to hear it but AOD will be responsible for most of the drain, I lose < 1% per hour overnight with it off and about 2% with it on. Totally agree about the functionality but I just set my AOD on a timer so it isn't on overnight.
The android system drain isn't unreasonably high given the phone has spent a fair amount of time idle, but you could try is going apps > show system apps > android system > turn off background usage (doesn't break anything that im aware of but will turn back on when the phone is rebooted)
Other things to try is wipe the system cache and turn off wireless device scanning from the location menu
Seems I'll have to test it out. Never before noticed a huge drain from using AOD on my old s7 edge and it's a lovely lovely feature. The Android OS seemed a bit high to me but unsure to why
S9+exynos also here. No issues with batterylife for me
I'm having the same problem. Around 16% lost at night. Maybe the last firmware update is to blame.

As someone pointed out, just disable background activity for Android System and that should do the trick.
I have been running with this option since launch with zero collateral effects; just remember to do this each time you reboot the phone.

You go to Apps and after which Show System Apps - Android System - Battery
You'll see the option there. I tried it for me it did practically nothing. Battery drain for Android System combined with Android OS takes more than 25% according to the battery stats. With a messily 3 hours of screen time including in that an hour of gaming with a 2D freemium game.
