Guess, I get to ask for help. [Ticket Closed for Now]

Background: I have had phone 11 months. I am very familiar with how the battery drain is while it is stock (WiFi ON all the time). battery lasted ~16h which is plenty for me.
Rooted phone, Battery Life on AR14 and IceColdSandwich (and others) was around 20h with WiFi on all the time and light use.
Recent Kernels (anything IceColdSandwich 3.0.0+ or AR 23+ (haven't tested between 14 and 23) cause a base of around 50mA of drain even when phone is locked. Battery life is ~8-10hours WITH NO USE. I have tried these ROMs without installing ANYTHING on them with the same results.
Current Widget does not identify an offending program from what I can tell.
WiFi off, the phone lasted 2d9hr of pretty light use.
I first started looking into WiFi when I forgot to turn off airdroid and unplugged the phone for 3 hours. I found AirDroid still running but could not connect to it via laptop or desktop until I tinkered with the phone a bit more and the WiFi connection cycled.
However during this time, the charge lost on the battery was a reasonable rate, and after the WiFi connection cycled it dropped like the usual rock.
What I've tried:
WiFix
WiFi polling interval increase
Cleaning/checking battery cover contacts
Changing battery covers
Battery Calibration (which is a myth from other reading I've done)
A couple of different programs like Juice Defender.
On the list to do:
Try a different Kernel
Root my friend's phone and trade him hardware (he says he never uses WiFi, so it won't be an issue for him)
/wrists
Thanks for all the suggestions and help so far. I understand that the problem is pretty obscure and seems rare.

on icecoldsandwich ive seen quite a few people show an improved battery draining using lordmods newer bfs kernel. maybe give that a try and report back?

btw, very good informative question. its heart warming usually we get 'my battery sucks yo, fix it!' haha

Here is some irony.
Exitz ICS AR25 has been on the phone for a couple of days and has lost essentially 10% per hour when not on the charger (been off work in my house) After the 4th day, I installed AirDroid and AngelCamera. I took it off the charger last night...
92% 6 hours later AND the phone has been awake(?) all night...
Seems I left AirDroid 'running' but couldn't connect to the phone through AirDroid until after the WiFi cycled...
I will see how the drain is today. I'll out of the house all day tomorrow (half a day in Denver), toggle off the wifi for a day at home, and then try your suggestion Darunion.
Here are a few screen shots (first two are old), and honestly, I don't know how much I trust the battery stats.
IceColdSandwich 2.0.0 pretty much shows that battery life I have been used to for a long time including before rooting. Not AMAZING, but not fail. (WTF Proximity Recaibrator 29% of Drain on a 16 hour day?) Also note this is about the same rate of drain I experienced with Existz AR14 last week. Light use and ~16-19 hours of battery life. Not amazing, but I can live with it.
IceColdSandwich 3.0.0 pretty much shows the battery life I have been getting with any ICS roms since.. well 3.0.0 was released. Oh and the voice call that is 37% of drain lasted less than 10 minutes.
Existz AR25 (someofthedrain.png) the steep drop was a 20 minute phone call...
And Finally Airdroidwtf.png is the same install three nights later (this morning) If I could get battery drain like THIS on a regular basis...
Anyway, I'll keep trying to isolate this down to the specific 'area' of the phone that is causing it....
Edit: and as for Darunion commenting about the information I've included... I'm a patient person, I don't want to be a drain on the community, and I have no issue trying to solve a ROM, APP, Radio, RIL, Or watever issue. I'm only posting because the issue isn't unique to a ROM but is unique to a time frame AND the issue is not solveable via Google or XDA search

Right now it is looking like the 'extra' drain on newer ROMs is directly related to the wireless being on*.
Right now the phone is at 1day 19 hours with 14% left and the wireless was only on for the first couple of hours this charge cycle.
I never thought there would be such a considerable difference between battery usage on any ROMs.
I'm going to continue looking around and trying to solve things, and I haven't quite made it to trying the Kernel, Darunion. It is on the list after I toggle WIFI on and off throughout a day.
*The rest of this post is just back-story I have ran the phone on stock for 11 months before rooting it and during that time, I got used to leaving the WIFI running all the time simply because the battery always lasted through my longer days and my-typical light-use. I'm near WIFI that my phone connects to about 80% of the time.
So after rooting, I had a little increase in battery life and I never changed this habbit, or more to the point, I was leaving WIFI on as to make it one less variable in drain while testing various ROMs and different build dates.

I was on battery for around 13 hours yesterday with wifi on for at least 8 hours of that and plugged my phone in with 51% battery remaining.

Yeah, I know this isn't a typical issue for most everyone, and am not implying so.
Likely it will end up being something very specific to the two WIFI networks I am at for 80% of the time OR something else that is very specific to my circumstances.

Have you, by chance, removed and reinstalled your back covers? I know it's unlikely, but since they contain the antennae, maybe they've come a little loos, resulting in higher imepedence connections.

I have not specifically toyed with the covers as part of trouble shooting. I will be sure that I look at them after my battery finishes charging on WIFI.
It does seem to be more a software difference, (I've casually be at this for the better part of 2 months) as I have seen expected performance when flashing back to a ROM I've used.
Thanks, I like being able to limit variables and this will be one I check before charging the phone again.
(What I'd really love to do is convince my brother or one of two friends who have the Inspire 4g to let me root their phones so I can trade them phones for a week and really isolate out hardware issues

fyi if you are still running icecoldsandwich. 6.2 just was released. Maybe give that a try?

Right now, I'd like to figure out WHY my WiFi is so bad on battery drain with later AOKP releases.
I'll try to rule out hardware issues (I'll look into antenna and MAYBE convince a friend to let me root their phone and trade them for a week... if not then covers at least.)
But likely this is something about newer releases and how my WIFI is setup. I don't live in a high-density area, so it's not because of too much wifi trafficz (I can barely see a 2nd wifi with any device and it's on the opposite end of the frequency choices.... by my settings)
Anyway, I am a very patient person, so I'll continue working on this slowly so that I can be thorough and find the real cause of the problem.
What I would wish is for someone to point me in the direction as to how WiFi MIGHT drain the battery so hard for later releases but not earlier. I'll be reading up more on logcat and how to read it in regards to wifi... but searching and reading is hard because 'wireless' and what not are very vague terms
Now at 1% (still) and 2d9h... is MORE than double my record on the first roms I tried after rooting OR my stock rom. and MORE than quadruple my record on any of the newer roms

I've swapped battery covers with a friend this past weekend, and the WiFi being on still drains the phone considerably (~8%/hr) when turned on. So if it's a hardware issue, it's not in the battery cover.

Wifi and blue tooth are very hard on the battery regardless. But 8% an hour seems pretty steep tho.
I would start by getting the current widget in Google market and put in on your home screen to monitor your Mili-volt ussage. If its running high like the 200+ constantly you have a lot of drain going on. When in sleep mode it should drop down to 0mv up to 8mv. If it stays high in the sleep mode you have apps waking your phone from sleeping. Which causes tremendous drain.
Next I'd try removing apps that have wifi permissions. To see if that drops your mv ussage.
Drop your notifications to less frequent times on your email and Facebook.
Remove any task managers or juice defender. They run constantly.
Google + is a massive battery drainer. Remove or limit notifications and sync as much as possible.
Also running wifi fix apk could also help. If you are knowledgeable enough you could also edit the build.prop to set the wife scan at a less frequent rate as well.
Last but not least get a toggle button widget for wifi and turn it off when not using.
I'd you follow these steps this will drasticly decrease your battery drain.

Thanks for taking the time for this response!
I started by running current widget for about a week and with a 3 different roms AR23(?), IceColdSandwich 2.0.0, IceColdSandwich 3.0.0.
I was stock for 11 months, and ICS2.0.0 was a little better than battery drain than stock. AR23 and ICS3.0.0 were terrible and pretty much ran a constant 50ma drain asleep or awake as a baseline.
I'd really like to figure out what the difference is with the older AOKP and the newer AOKP, but that may never happen.

I've been testing with stock roms since a couple weeks before I posted this thread. This is because current widget didn't really show any specific program causing the issue, so I wanted to make sure that I didn't have some issue from my installed programs.
The most I've installed (out of necessity is AirDroid and AngelCamera) in the past few weeks. Both were installed when I ran without wifi on one charge for 2d9hrs.
(I don't have a google+ account, I don't have juice defender or any task managers aside from the stock rom)
Also running wifi fix apk could also help. If you are knowledgeable enough you could also edit the build.prop to set the wife scan at a less frequent rate as well.

This is likely going to have to be my solution. Just run cell data all the time unless I am doing something specific like downloading files or uploading pictures.
OR
Maybe I can convince my friend to let me trade him phones (root his and nand backup and then restore all his stuff to my phone) and see if it is about the same drain. His phone was bought a couple months after mine AND from a different vendor, so it isn't going to be out of the same manufacturer's lot.

Thanks again. I'll definitely try the wifix along with the rest of your suggestions that apply

I'm in the same boat you are. I'm running ics aospX ar-26 and I can barely get mine to last from 8 til 4. Wifi is pretty prevelent around here and I leave it on most of time. I guess I could try turning it off til I need it. Anyway I'll be following this thread.

You also might consider reading the threads on calibrating battery after flashing roms. I made the mistake of flashing a rom @ 40% battery. It jacked my stats all up. The new rom thought 40% battery was actually 100%. It had my stats all screwed up too. Except mine was Bluetooth. Showed running at 60% of battery ussage. So don't trust that system tool. Because the display is almost alway gonna be the biggest drain on the battery. An app called "spare parts" is a little more accurate.
I ran the gambit on this one finnally got my battery back to normal for me anyway. I've never seen a full days use with out charging. Get about 14 hours Max now. But the calibration steps is the way to go.

I actually have read quite a bit about battery calibration... and before I flashed a new ROM, I've made sure that current widget has been tracking 0ma for a while. (Only reliable way to be sure you have a full battery from what I can tell)
The batterystats.bin file and calibration has been ... contended in a number of places, mostly stating that when taken off the charger 'full' the battery stats file is overwritten... which makes calibration a non-issue (assuming that you occasionally charge your phone for a while after it hits 100% from time to time)
The problem is that the WiFi mA draw is HUGE compared to what it should be (in theory from reading other people's logs), and it's not because of the battery cover. AND It's not as bad in older AOKP ROMs than it is in newer ones. SO it could be a hardware issue exacerbated by a change in how WiFi is handled, but the hardware issue was never noticed because the battery life Stock was sufficient for my needs.
I've been busy working so I haven't been able to continue troubleshooting the phone (damn my patience), but Mondayish, I'll likely have traded my phone with a friend and root it and flash a new rom and see how the drain is with completely different hardware from a different vendor from a different lot of phones.

I had a similar issue with wifi. I changed the build.props wifi supliment scan from every 15 seconds to 180 and used the wifi fix manager apk. That seemed to help. Coupled with a proper battery calibration and I'm back to my display being the major battery draw.
So don't know if that helps but it seemed to work out my bugs.

This I can do right now.. and given I'm on the same, unmodified AR24 release, I can observe it for the weekend before I annoy my friend about his phone.
Seems the WiFi scan interval was already set to 100... moved it to 180 anyway.

I used to have this issue. I could literally see my battery draining while I was using it. I keep wifi on most of the time. I recently purchased an anker battery online. It is AMAZING! My old battery wouldn't last more than 6 hours or so. Right now I'm at about 14 hours on this charge, and I'm at 47 percent. Try swapping his battery for yours for a day or two. Another thing to try is different radios if you're losing power to cell standby.

The phone ran for 2days 9hours with WiFi off and lasts for 8-10 hours with WiFi on. I am pretty sure that it's not a Radio/RIL or a Battery capacity issue. ;(

[Q] battery dropping significantly?

I've been using the latest ota 44s rooted, but with no modifications. its probably the most stable yet. no issues apart from this. despite the battery being actually quite good, i get 6+ sot within 40+ hours. but i'm getting an issue where according to the battery monitor, it drops a few percentages in one go without me actually using the device. its still on deep sleep. no wakelocks or anything like that.
Could it be that the battery stats is not being monitored properly by the phone? where the phone is going down steadily and then it realises the battery is at a slower percentage than its already displaying?
or is it something else?
This has happened to me several times previously. though no reboots, and battery life is still good.
as you can see here it drops from 86% to 77% whilst the -mAh is at -9mAH

Use a app such as better battery stats and debug your apps. There's most likely a app causing the phone not to properly deep sleep

i used to use bbs, but then found wakelock detector easier to use. if i install v2.000b7, do i just go into the advanced setting and add debug info to logcat?

Re: Phone deep sleep battery drain
I have also come across the sudden battery drain issue this past week. My phone deep sleeps well and I can find no wakelocks. It appears to use excessive battery when idle. I have tried a fresh, blank install of CM11S 44S and that didn't resolve the issue. I have since moved to Cm11 nightlies and that slowed the battery drain but I am losing 12% battery per hr when idle and the phone is staying warm. I do not understand how this happened and why it just spontaneously began. A fresh install with no additional apps, and no problems entering deep sleep. shouldn't be doing this This phone was brilliant for battery life and I cannot work out how to resolve this.

I have checked that and it appears to be sitting at the minimum 300MHz as far as I can tell. Since posting I have tried PA 4.6 for 24 hrs, no additional apps, and now I have moved to Liquid Smooth Lollipop nightly just to see how they compare. Even changing radios doesn't appear to have any impact on the power consumption.
When using GSam battery monitor on both the CM11 and PA (both behaved similarly) my phone was using anywhere from 500mA to 800mA (minimum screen brightness) for no apparent reason. I am unsure what usage this phone should be to be honest but I think that is high.
On Lillipop, the category 'Miscellaneous' is by far the greatest usage category and is seeing 2-3 times expected mAh drain compared to its computed usage, though I am unsure how that is worked out.
The most my phone will last now is 8hrs standby, in deep sleep. I am beginning to wonder if there is something wrong with the hardware of this device now. Perhaps the power regulator... Not sure what test to do next TBH

The next thing I'd do would be a complete wipe and flashing the fastboot images. This still return the device to a completely stock state (including wiping the user data), leave it like that (don't install any apps) and test for a day or two.

Fresh install, data off and left to own devices for a few hours and it is deep sleeping like you would expect, but a neat linear drop in the battery of 10-12% per hour as before...

I saw the same type of behavior while running CM11 based ROM. At night, I would put device into sleep (no data/no wi-fi/no sync/etc.) - basically everything off. In the morning, it would still show 100% - but then quickly drain several percentage each minute for the first 10 or so minutes. It was like it was catching up to the correct %. I have used wakelock and BBS and nothing sticks out. I also set Google Play services to stop wake (which did help battery life a lot).

Low signal battery drain

Hey all, firstly I'm running stock everything on my nexus 5. 5.0.1 with stock kernel and root. Using twrp however for recovery.
When I go to work I get really bad signal and my battery usually drains away (that's understandable) however when I leave work and head home to better coverage the phone stays hot (36°c) and continues to drain with "android os" having a large awake time. I usually fix this by restarting the phone.
I would like to know if there is any other way to fix this without a reboot? Sometimes it happens sometimes it doesn't, but it happens more often than not with the phone draining 10-20% per hour and staying continuously warm @ 35-36°C during idle.
Thanks in advance !

I assume by "36C" you mean battery temperature - I would not ever even take battery temperature into any sort of consideration at all unless it goes above 60-70C. Keep in mind there are also throttles - when the battery reaches a certain temperature and when the CPU reaches certain temperatures, the CPU clock rate is throttled to reduce heat - the CPU will almost always throttle before the battery has a chance to even reach near it's throttle temperatures. Keeping an eye on the battery temperature is ultimately pointless as it is meaningless unless you know you have a physical battery issue, in which case you should be replacing it immediately anyways.
Of course, if your signal is low then your signal is low and there isn't much you can do about that, but since you have root access, I recommend visiting the stickied battery life help thread and posting the recommended screenshots. Saying that your battery is "hot" and "Android OS has a large awake time" doesn't say much if anything at all.

It may be something using data. The stock battery stats will tell you how long the mobile radio/data was active I believe. If location is on, it may be something using it to update it (probably a Google service).
Another trick that seems to help is to delete the cache. IDK why but the phone seems to run hot until you do this if you OTA upgrade from KK.

Hmm, I have gsam installed and during when the problem occurs, the android OS awake time corresponds to high kernel wake lock. Since I'm off work today the problem hasn't occurred so I can't post screenshots. But even when it does the battery page or gsam or anything doesn't show anything unusual except high awake. I dont have Better battery stats anymore so I can't get a better idea beside what gsam offers me. But since the battery idles at a higher temperature than normal I suspect its because something is running in the background keeping it awake and constantly using data or something. And I don't have gps on.
I've also come fresh from 5.0 with a full wipe before installing via twrp. I never ota on my nexus 5.

Android System huge battery drain

Does anyone else have the issue where android system is consuming 35+% of the battery? Looking at the stats it seems like one of the bundled services is keeping the radio on for 14/18hrs its been on.

Have the same isssue
Yeah, I'm having this issue too. Android System is consuming HUGE amounts of battery for me.

Thought I was the only one but glad that's not true! Still got good battery stats with the android system drain nonetheless.

Charged mine to full last night right before hitting the sack.
Woke up 7½ hours later and it had consumed 33% of the battery just sitting doing nothing bar getting email & polling (presumably) for Facebook updates.
And that was with Power Saving enabled. Bit disappointing, hoping when I disable auto-sync that it'll kill the drain.

There's lots of services running under Android Systems disable the ones u don't use, I have disabled some got better battery life, still testing some others...

The hardware on the phone is great, but touchwhiz drives me up the wall. I'll be happy if and when we get anything AOSP based, CM being the holy grail. Nice to know I'm not the only one getting this battery drain. I've disabled pretty much everything that's able to be disabled, as all I use is google services.

Same problem here.... Huge Android System battery drains.

I've played around with several things, and as of yet I haven't gotten it to stop other than turning off WiFi. Anyone found a fix?

Mine's more a combo of Android System and Google Services... both take up a majority of my usage... Services typically being a bit more.

Why are there two android systems? wtf...
Is there any way to reduce cell standby?

Same sh*t here. Went to bed last night fully charged, and 7-8 hours later, wake up with 23% of my battery gone.
I'm starting to wonder if moving away from the Nexus line was a mistake. I started running again and the N6 was just too big to lug along with me, on arm or in a waste band, so I decided to try Samsung.

Just got my S6 and I noticed this right away. Last charge I had 2:42 of SOT and "Android Systems" used 47% of the battery. I was just watching Netflix and YouTube mostly. My overnight drain is also quite high, about 1% every 30-40 minutes of standby.
Is that normal for most S6 owners?

To all:
Turn off VoLTE, turn off WiFi calling, install CPU Spy, ensure your phone is going into deep sleep. If it isn't, flash the stock recovery with Flashify, wipe the cache with it, then flash TWRP back with Flashify.
Post your results.

Turn off VoLTE, turn off WiFi calling, install CPU Spy, ensure your phone is going into deep sleep. If it isn't, flash the stock recovery with Flashify, wipe the cache with it, then flash TWRP back with Flashify.

Is this only for people who already flashed TWRP? I'm stock rooted and seeing this.

This is for everyone. If you haven't flash TWRP, then simply wipe the cache with stock recovery.
I just assumed most people would have TWRP flashed, my bad.

I am guessing that that this is an Android problem as the Galaxy S6 Edge has the same problem with battery drains.

I'm not rooted and I don't plan on doing so. I'm not sure of any other options. I unplugged it last night an let it sleep. Android system used about 14% of the battery. And I lost 20% charge. Cpu run time was 38 minutes too. and I never even woke it up post unplugging it.

I believe this Battery Drain Issue is a Lollipop issue. Was haing it with my One Plus One, I fixed it by going into privacy Guard, and going to Google Play Services and not allowing it to stay awake, and start by itself.
Ill find the actual thread and post it, same issues happening with a lot of phones using lollipop

Battery drain on a new device = bad flash (very common on android devices, first run)
1 wipe the devices and start it again from factory problem should go away. (at least the excessive drain anyway)
2 Ensure you have updated the Samsung Services app (this was responsible for most if not all battery drain issues if you reset your device)
3. Turn the bloody Screen brightness down and turn off Adaptive display (way way way too much battery drain using them)
4. LTE off and Cell data off if you on wifi, your wasting battery power communicating with cell sites you arnt using, the weaker the signal the more power you will drain for no benefit
6. GPS / Loc data off unless you need it even then wifi / AGPS is usually more than accurate, remember GPS + poor sky visibility = more power used to get a loc.
5 NEVER measure battery life for the first 24 hours way too much stuff syncing and updating to measure with any accuracy.
I get a solid 2 days out of the S6 with mixed use and a screen on time of 2:30 could get that upto 3 hours but i have a hearthstone addiction

As mentioned above, I highly recommend wiping the cache, even when not rooted.
Also, worst comes to worse, i'd completely redo the phone from scratch via the Smart Switch software samsung provide.

Phone idle using a lot of battery?

Sorry if the question has been answered before but does anyone else get a lot of battery drain due to 'phone idle'. I'm unsure whether if deep sleep not working or what but have never had this problem with any other phones I have had.

Yes, I'm definitely experiencing the same problem. I left the phone overnight and it lost almost 7% which is a lot compared to my old Z1 (only 1-2%). Other time is also similar. Sometimes, it feels like it as if actively using the phone actually uses less power than leaving it idle. Looking at the battery chart seems normal but the phone actually discharges fast on standby (sometimes I lost 25% after just 4-5 hours standby) I'm really want to know if others experience this as well and how to fix.

Yes I'm having the same problem.. Phone idle taking more drain than screen right now..
It's deffo a bug with this 7.0 update.. Hopefully it gets fixed in next update..

My battery sucks now after the Nougat update! Drains really quickly on standby. I even turned WiFi scanning off but it didn't seem to help

I am facing the same issue too
Phone idle appears at the top of the list, claiming 135 mah
While my screen states its using 49 mah

Similarly and annoyingly. Since Nougat my phone barely deep sleeps.
My phone was deep sleeping amazingly on mm. But now it barely deep sleeps. Ridiculous update which now requires me to perform a clean full wipe install of Nougat. Which currently I have no time for, hence my battery dies ridiculously fast. Annoying and not what I was expecting, this removed my excitement away from receiving the new Nougat update and instead am left with work to do to get this one back to par.
This has happened to me before on previous Sony phones when installing new ota updates. Clearly something Sony is good at.
For the OP - this is one of the best apps to determine CPU behaviour, simple and to the point. Particularly scroll to the bottom to obtain how well or not the phone deep sleeps.

Since upgrading via OTA to Nougat my device barely deep sleeps, rather it sits at 307mhz when idle. Battery gone to sh!t. Forced to do a factory reset fresh installation (when I get enough time to.)

To save everybody's time, I have performed a clean install of nougat and the issue still persists

Thanks,
It's seems the idle just stays on all the time even if the phone is being used..
Sony needs to release a patch for this asap..

Clean install, locked and unrooted, DRM in tact?
Still unfavourable deep sleep?
Then that surely is pointing to a inherent issue with Sony Nougat.
However why isn't everyone here with XZ Nougat complaining the same?
We need more input.
In the meantime I will need to bite the bullet and reset my phone as well and report back.

Been using kernel auditor to check usage. Will reset it and will use the phone as normal tomorrow and report any findings.

I got the same problem with you too, 7% after night, my old phone was Z1 to compare too. After update to 7.0 then back to 6.0.1 battery drain is less, but still more than normal.

I also Started to get huge Phone Idol drain (top of battery usage) after OTA update to Android 7 on Stock unrooted, Ive done a complete fresh start through xperia companion and still getting big drain from Phone Idol.

Got the same problems you guys are facing.
My phone did drain from 100% to 88% in just 2 hours (Display on: 35 minutes half brightness, phone calls 10 minutes) and its on WiFi not even mobile data. My girlfriends phone did drain about the same with 35 mins display on BUT calls of 45 minutes.
Oh and idle yeah on WiFi about 1% every hour and on Mobile Data 3%/hour.
This is really bad imho and it's been 2 times I've repaired the device via Xperia Companion. Funny about this is, that always on the first run I get a message "Firmware could not be repaired". Then I restart the whole process and it does just fine. Same with restoring images/videos.

I've started to notice my phone idle is near the top of battery usage. Initially after installing Nougat, battery life was great. Now I narrowly get 5hours of SOT. Currently at 70% and phone idle has used 19% of battery at 196mAh and SOT 1.5hrs with 182mAh. Not sure why the phone is not sleeping.

I upgrade to 7.0 again recently, and it only cost 1% per night, it's quite good . But battery consume while using is not much improvement like idle.

Facing the same problem, though i dont think its actually draining in my case, the phone deep sleeps fine but the drain with screen on is just appaling, since I got it I only got 4 hrs Max SoT thats with MM and N. It just seems that the battery generally sucks.
As of now, i have 84%: sot 23% 48 min - phone idle 20% (time on 4 h 35 min). By this it means i'll get about 3.5 hrs SoT which is normal in my case (though not good in my opinion)

I've just updated to the lastest .374 from .327. From what I experienced, the standby battery life have improved. I left it overnight and it only lost 2% (unlike 7% like before) which is probably ok for now.

Do you want to say.....that leaving the phone all the night....it lose 2% only???? I can't belive....normally it goes down by step of 2/3% for hours....so in 7/8 night you have to lose at least a 20%....minimum....

Well my battery result probably need more testing but it has never lost up to 20% per night. It would be outrageous if that happens. Are you sure there isn't anything that continuously running in the background of your phone? You could try a factory reset? Usually losing that much of battery per hour is only when the phone is actively being used, I think.
