I want to flash to a newer ROM, but then i'll lose my battery-calibration. I will have a couple of days a real bad battery prestation and my battery will also not get better of it. Doens anyone know how to back-up the calibration and how to put the settings back after a flash?

That is not possible since the ROM has to be trained to the battery. It is really very simple. All you have to do is run the battery dead on the new ROM and then let it recharge and it will be calibrated. There really is no calibration data so much as training the ROM to know your batteries empty state versus full state. The fastest way to run it down is turn GPS on as well as WIFI and BT and leave them on. Your battery should be dead in less then half the day.
Also please do not double post. We see your post and if no one answers then no one answers.

i agree on the first part but disagree on the rest
running the battery dead isnt good for Li-Ion batteries, and for running down the battery dead faster would actually put a lot of stress and heat (if youre connected to data and running very heavy apps that uses either wifi or data, or even A LOT of CPU) on the battery as well, heat is a no no for the battery, just let it down by leaving the backlight on and turning off auto standby, works for me and its going good
read some of this on the bottom, might help you

BATTERY SAVING TIPS
The first few days
• Immediately after flashing, you will probably observe very poor battery performance. This is due to the charging circuit having to reset itself.
• The battery meter will not settle down and give accurate readings for a few battery cycles. Give it a few days.
• For the first few battery charging cycles, try to charge to 100% with phone off and then allow battery to drain down quite a bit before recharging. This is so the meter will calculate drain well.
Recommendations
• Make sure you followed all of the flashing instructions to the letter. Especially the part about the hard reset.
• Backlight is set to high. You might want to change that.
• 3G is on by default. Recommendation is to turn it off when you are not surfing the internet.
• Don't drain your batery all the way down until it dies. Not good for these types of batteries.
• The GPS sucks the battery dry. If you want to keep track of yourself, consider something like GPSToday that only wakes up the GPS once in a while.
• Maybe you don't really need aGPS enabled. Disable and check GPS lock times and battery drain.
• Applications that run from the storage card consume more power so install oft-used or background-type applications to main memory.
Troubleshooting
• If your radio does not match your rilphone.dll you can get crazy bad battery drainage. Use the recommended radio or spend some time working out a good combination for your phone/carrier/location/usage.
• Check to see that some application is not still running in the background. Check, do not assume. USe the full Task Manager application.
• Check to see if the screen is still on when you expect it to be off. Soft reset can fix that issue.
• Some radios work better with some carriers and locations. Asking everyone to tell you what radio to use may not give you the best answer. Be specific about your situation.
If you have tried all the above and still can't get over a day with moderate use, you may actually have a bad battery. Try getting a new one that is made by another manufacturer.

I'm not sure that it helps (I do it anyway, lol), but I think it's a good idea to flash with the battery fully charged (and maybe plugged in, if you flash off a card).
But when the ROM is trained, it has to save tha calibration data somewhere in it's system? And when you can find dat data, flash a new rom and put that calibration data back, you do not have to train your phone anymiore, right?
If you flash your rom, You should be sure toloose preety much everything of your settings, as far as I know. And so on you wont be taking anything alng (as long as you havent a good backup-tool with you), ...just adjust the settings another time (If they are too many, tell me what you did, maybe I can help my own sttings ^^ (Hate the battaryusage aswell, ...)

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....)

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.
I just have my new Galaxy S2 and first thing I noted is that battery drain overnight in flight mode is significannt. I had a ZTE Blade which stayed in same % even for a whole weekend in flight mode, using CM 7 or the best GB cooked roms.
I tried many ROMs, including stock XWKK5, XILA2 and custom, doing a full wipe install and in every case they typically loose 3-5% in one night or 8-10% in one full day. Only ROM that seems to keep battery most inf flight mode CM 7, loosing some 2% in 24h (but more than ZTE Blade). Next better is The-GingerMod 0.8. I tried killing every running process in installed ROMs but consumption is still high.
In ZTE Blade made no sense turning off the phone at night since startup lost more battery, but with S2 it's better to turn it off if still has battery for another day.
I can understand that phone has some parts always running, and that S2 has a large screen that consumes more power than smaller phones, but I find strange that in flight mode, screen off, everything off there is such a difference with the ZTE Blade.
Any opinion about this?
I tend to put my phone in flight mode overnight (~8 hrs/because I like to sleep when I'm in bed ) and I normally lose 2% (0.25% per hr).
At the end of the day it's easy to overthink/stress/obsess about losing a few % overnight when you've got easy access to a charger most of the time. What I mean by this is you can spend a whole lot of time trying to find/chasing that extra couple of % in battery savings & either not find them or maybe only find 1-2%.
Obviously battery drain will depend on a whole bunch of factors not limited to kernel, rom, how you have your phone setup (apps & so on).
You may be experiencing wakelocks when the phone is in flight mode that might be causing the drain to be a bit higher than it could otherwise be. Get hold of BetterBatteryStats. Install it, read the thread on here devoted to it & you can post your wakelock details to that thread. There's a bunch of guys who post to the thread regularly (including the dev) who might be able to help you nail the wakelocks & maybe squeeze out a few % of savings.
I installed BetterBatteryStats but as for now my knowledge is very limited to decipher the processes, anyhow as I said I tried many ROMs after full wipe being intrigued for this behaviour, so they were clean installs with no app added, but I see that even custom ROMs if they're based on official and no removed apps have many things added in comparison to the more vanilla ROMs the Blade has. This explains why CM 7 (or The-GingerMod) s the one that drains less. Have not tried 'lite' ROMs whith removed apps.
Just wanted to decide if it's better to turn phone off at night or just put it in flight mode.

i am currently using a lite rom based on XILA2 and i have to say it is the best i have used hands down. I never use flight mode at night or anything else. All i do is choose the governor of my choice and that is it. Some governors have a screen off profile. That saves you having to add an extra profile in the cpu apps if you use one. Anyway choose a rom plus a kernel that gives you great battery and stick a governor that has a screen off profile and your phone will sleep like a baby
Now that you've installed BetterBatteryStats, charge your phone fully before you go to sleep, do a reboot & leave it in flight mode overnight as you have been.
If you want to find out if it's possible to squeeze out an extra few % of battery, have a read of the BetterBatteryStats thread on here (search for it), read the first page or so, and the last 10 pages. That will give you an idea of what screenshots you'll need to post/what info you'll need to provide for the guys in that thread to help you out.
As to whether it's better to turn the phone off or put it in flight mode @ night, you should realise there's no right answer to that. It's your phone after all. Battery life isn't the be all & end all as I hinted in my previous post. Obviously if you want/need your phone fully on at night (normal mode), then you're going to lose battery & you'll be happy to lose battery because your phone will be switched on. It's entirely up to you.

I can be a lot of things besides the kernel itself, for instance:
1. Sensors! Turn off motion sensors...
2. The lower cpu freq is too high. Use the lowerst possible value.
3. The cpu governor it switching to the higher cpu freq to quickly. Try interactive.
4. Constant updates of some programs, like Twitter or Facebook. Even if there is no network connection they still run on their scheduled times. I just turn them off.
Hope it helps!
hi
is it required to battery caliberate after flashing new rom?
and when ever i reboot my system either battery jumps from 10% to 30 or more
or becomes less than 10%..
if i should then which app should i use?
any guidnace
plz
TY
No such thing. After you flash a new rom, charge the phone to 100%, turn it off, remove the battery for 30 seconds, replace the battery, turn phone on, enjoy.
Anyone selling you the whole calibration thing is selling you voodoo.
hi
thanks for your reply
plz suggest me best battery app with battery saving feature , suggestion on what we can do with remaining battery , expected full time charge , complete graph or battery usage history by apps?
paid or free , tell me best one
thank you
There's lots of battery apps on Google Play, there's no such thing as the best one, go have a look under the Tools section in Apps (you'll also find some under productivity). Stay away from apps like Juice Defender that claim to save you battery by doing things automatically which you can do yourself in two seconds, these have been proven time & again on XDA to use more juice than they save.
ivl try battery monitor
thank you
No probs ;-)

Wouldn't that procedure above be considered calibrating the battery? LOL. J/K. Couldn't resist .

actually it cannot. this way you only help the system in your phone recognize full capacity of battery (which is not even full because not one battery works at it's full capacity - but it's fullest you will get at this point of your battery life). when it's about calibrating - listen to MistahBungle - it's all voodoo. you cannot calibrate li-ion battery unless you kill it and then revive. by killing it I don't mean depleting it in your phone, because even when phone shows the battery is fully depleted it's really not - there is still some juice in it. you'd have to use e.g. special charger which can drawn juice out of battery and make it really empty. only then your battery is dead and useless. you may revive it by applying cca. 5V but actually it not always works. so you cannot calibrate your battery in home environment.
what you can do is "re-calibrating" so called fuel gauge (description under links given below) and you may also help your system recognize the real state of your battery charge. sometimes it happens that systems readings are wrong and battery is on 85% but system is reading it as 50 or 100%. to help it read battery chip correctly you do the thing MistahBungle so helpfully described. sometimes you even don't have to do it but wait 2-3 charging cycles and system will adjust it's reading itself. by charging cycles I mean charging like from 20-100%. why not from 0%? because even if it's not a real depletion state, li-ion batteries doesn't like the state of being discharged too much.

and is there any way to stop auto startups of apps?i have around 200apps and most of them i use around once a day or not even once
i use android assistant to manage startup but it does on boot and after some time if i check running apps most of apps will be there running
is there any app to block it running automatically? not just at startup ? full control like anything?
thank you
actually I cannot help with that. I don't use such a software and really don't believe in it. but, the fact is that I do not use so many apps. other fact is that surely there is some useful software that could help you with that task, i just do not use one and personally I'm not interested in it. I know that perhaps the best method is to freeze them with titanium but if you use these apps from time to time then it would become complicated and not worth the effort.
still I have few questions:
why would you like to stop them from working? do they drain your battery? if so then check your logs with bbs and find out which ones are draining, try to change their setting or get rid of them, or at least close only these ones. long time ago I was fighting with some apps that I do not use often and they start themselves from time to time. I didn't want to get rid of them, so before every night I was killing them one-by-one from applications menu (actually most of them didn't wake up until I ran them myself). finally, after many tests I got to the point that it doesn't make any difference. apps I was killing, even if running, didn't use any recourses, didn't produce wakelocks, they were just using some RAM. and if it is the reason of your concern then do not be worried - they may use as much RAM as they want - android will free RAM when it will need it.
now I do not kill any apps and by night I lose 0-2% of battery which is my only concern - what should we care more? CPU, RAM - let it work as long as it doesn't stop us from enjoying our phone and make a usage of it uncomfortable.
and if you're worried about packet data then you may limit it for each app using system menu in ICS.

Thanks dude. I also have the similar problem. I have spent months on it without any improvement. Now I'm quite frustrated and not optimistic on the solution you have provided towards my issue, but your decription gives me a lot of clue.
But my problem is even more tricky, I would like to share it here so see if anyone have met it before, or if I need to start a new thread to deal with it:
The problem can be generally decribed as below:
1. When the battery is fully charged, unplug and consume the juice until the level reach around 30%, then the phone is shut down automatically; after I plugin the power and restart the phone, the battery level is displayed as 0%;
2. After charging for a while from 0% , restart the phone and you will see the battery level directly goes back to 50%, but still with very low voltage;
3. Changing with a new battery won't solve the issue -- though the new battery itself may also have problem(not sure if it is genuine), but I don't think a fake battery and an old battery should behave almost the same, so I don't think it is the battery's problem; criticize if I'm wrong
4. Re-flashing a new rom won't solve the issue either. I have tried different CM9 nightlies and now I'm using CM10 nightlies, none of them is immune to the problem;
5. Clear the battery state won't solve the problem. It is hard to say whether it improves the situation at least a tiny bit. I mean it may work somehow, e.g. My phone used to be shut down at 50% battery level and now it can last to 36%. But it never totally solve the problem once and for all, so I still don't trust this caliberation thing may work.
I hope I have clearly stated my issue. I'm so at the end of my patience, this little bastard have been always torturing me You guys are the last I can count on I really hope I came here earlier so as not to have wasted so much time.
This one is a weird one...
About a week ago, I needed GPS to navigate out of a town - I waited and waited and didn't get even any satellite reception... It turned out that I found the way by myself and just closed the navigation. A few days later, same situation, no visible satellites at all... Didn't have time to reboot the phone, so I just closed the navigation and went my way.
Now, something weird is going on with my phone... Usually I get about 2 days of battery life - but since last charging, it looks i will get about 4 days and I have been using quite a few apps, browsed the net, made SIP phone calls, made normal phone calls... (more than normal usage for me anyway).
Is it just me or are those two things connected in any way? Can it be that GPS has crashed somehow and in the result, lowered the power consumption of the phone? Is it possible to turn off the GPS 'on demand' to extend battery life?
All other stuff is working like a charm...
I am using stock ROM (4.1.2, radio: I9100BULS1, build: JZO54K.I9100XWLSD)
Why do not you try installing a different rom see why.

Well, a colleague of mine has the same phone and has experimented with various ROMs - none gave him so much more battery life. It is not the question of which ROM is better in terms of battery life, but whether some weird (non-functional) state of GPS (I have it normally disabled almost all the time via drop-down menu) can cause the extended battery life. And if this is possible, can this be done on purpose?
The ROM stock give many problems, you're not in fact the only that the strikes. I advise you to try some Sammy Rom! JellySNAP v6 and, for example, a great ROM based-stock Sammy

I am bumping this topic to continue the discussion...
I am aware of other ROMs and have experimented with a lot of them on another phone. Due to extensive set of installed applications, loads of data and relatively stable stock ROM, I haven't really taken the time to do the transition.
So, I am not really looking for a solution to fix GPS, but the opposite way. I want to know if I can break GPS on next boot in order to obtain such long battery life... How many days of inactivity do you get with non-stock ROMs? At the moment, I am getting 5 days of light use WITH stock ROM (WiFi, Bluetooth, data disabled, only connected to mobile network to accept and make calls). I was never been able to do more than 3-4 days and my battery is now over 2 years old....
So, please, don't try to persuade me to install other ROMs by stating that they are better and more stable - list your battery lifes in case of light use or inactivity.... Do you get 5 days on 2 year old battery?
If you think breaking GPS is somehow responsible for greater battery life, you're going to end up rather disappointed. That concept defies logic given GPS only uses battery when you're actually using it. How is it possible for battery life to somehow magically double as a result of GPS being 'broken' ?
Thus far you've not provided one duplicable 'test' that other people can try to see if they get similar results, and all you've done is blabbered nonsense in a couple of posts. I mean, do you honestly think people here are going to delete a bunch of GPS system files to see if they can get some magical extension in battery life ? I know I'm not, because trying to put that stuff back when your silly theory doesn't work is a pain in the arse.
Did it ever occur to you that given the battery is two years old it's quite probably on its last legs & is very likely chemically unstable (this is why 'old' batteries swell up & sometimes even burst). This instability might be causing the extra battery life as the battery approaches the point where it's no longer useful. Put it this way, that's far more likely than busted GPS causing the extra battery life.
So, please don't try to persuade us that breaking GPS somehow doubles your battery life with a 2 yr old battery. Logic & almost 3 yrs worth of different people's experiences on here with this phone just don't support your ridiculous assertions.
That was a spicy reply, MistahBungle
Some facts:
- No system update was installed in the last month
- No application has been removed
- System hasn't been rebooted for a month or so
- Never got more than 2-3 days out of battery in idle
- Battery is 2 years old and is physically not damaged or swelled
- GPS isn't working (not even receiving or predicting a satellite on a clear day)
- System is rooted for a year or so
- Battery lasts 4 days now (instead of <2days a month ago)
- Connected to 3G network (no data connection)
I would try to reboot my phone, but I am afraid that it will all be over...
So, to stay with firm facts - how much battery life do you get with alternative ROMs in real life? Is 4 days (5-6 days with new battery) something usual?
That concept defies logic given GPS only uses battery when you're actually using it.

Can you then explain me the difference between Cold and Warm GPS start? As far as I know, phone tries to keep as accurate GPS time as possible and a bunch of ephemerisis data in order to decode GPS data faster, next time you enable GPS. This defies logic that GPS is completely OFF when it is 'disabled' by GPS button in Android system.
I mean, do you honestly think people here are going to delete a bunch of GPS system files to see if they can get some magical extension in battery life ?

No, I don't expect it to. I am looking for information whether anyone experienced anything similar.

In Lithium-powered batteries, I haven't come across the fact that battery capacity is increased with battery ageing and sweling up... On the contrary, internal resistance goes haywire and capacity drops, contributing to even more heat being spent internally by the battery and speeding up the process of degradation...
I may have not been cooking my own ROMs and writing drivers for phones, but I have quite extensive background in embedded systems and electronics. Battery life can not increase just by itself - there must be a reason... My lifestyle hasn't changed, my environment also didn't change, other phones at home didn't experience such battery life extensions... The only thing that I noticed is that the GPS is not working. I opened this topic in order to discuss whether that's the true cause or not.
So, based on '3 yrs worth of different people's experiences on here', what could be the cause for such prolonged battery life? How can I debug it by myself without rebooting the phone?
My wife and I both have the Galaxy S4, verizon flavor.
My phone's battery usage is very nice. Most of the time I go to bed with 30-70% left on the battery. Hers does the same. The only difference is I use my phone a lot and she barely uses it during the day. A couple of texts, maybe a phone call and on occasion an internet search. Before this happened, and I don't know what was the tipping point, she use to charge her phone every third day, now she charges it every night.
Her phone is also 6 months newer than mine. Both are running stock, both are Android 4.3. I have both phones setup as close as possible so I can make comparisons between the two. Obviously she has different needs and will have different apps running/installed.
I have taken all of her apps off the phone and it hasn't changed the battery problem. I have reset the phone and still the battery drain persists.
I have put Battery Monitor Widget and GSam on her phone and I really haven't been able to locate the offending app/program/function. The only possibility is the 1013 system and "AudioOut_2". But that seems unlikely as this drain is about every 20 minutes and goes on all day.
Usually she runs with her phone in minimal activity. Data off, Sync off, GPS off, Power Saving on.
Here is a chart from a while back, everyday looks similar with the drains. My phone has long periods of straight white lines when inactive, hers just keep going down.
can't post the image of the battery chart. Gonna make it more difficult to solve.
Just wondering where to look and if this is something that can be solved or is possibly a phone problem/defect. As I mentioned, mine works nice and I have it setup as close to my phone as possible to get results that can be compared.
first of all im no expert, but i think it could go either way. before assuming its hardware it wouldnt hurt to back everything up, try a factory reset and a wipe mk2 odin flash. then seeing if the issue persists. just throwing my thoughts out there. hope it gets resolved regardless. :good:

Have you tried Better Battery Stats + a Wakelock Detector? Between those two it should be really easy to see if this is a software problem or perhaps a bad battery.
I'll link you to the wakelock detector I use. In my opinion it's the easiest to use.
Here

You can see wakelocks in BBS as well.... But I just like the options this one gives

I haven't tried BBS+, but Wakelock Detector has been running since the problem was detected. That is how I found the 1013 and Audio2_Out running. At the beginning it seemed to correlate with the problem but as time moved on it seemed less and less the culprit.
I haven't really found anything using wakelock detector. I could give you some stats off of it tonight when I have access to my wife's phone again.
Any stats that you'd like me to post I can do that. Eventually I'll be able to post that Battery Monitor Widget graph so you can see what is happening.
Pretty sure we can rule out a bad battery. About 99.9% sure.
First things first I would swap batteries between the two phones. Lets rule out a faulty battery first, because trying to figure out battery drain with a faulty battery can be maddening!

OK, all day with swapped batteries. Same thing. My phone is fine, her's is still doing the same stair step battery drain.
