I've read in a bunch of other threads that people are getting awesome battery life out of their Z or G2. Mine is okay-ish. I had a hero before which seemed a bit better. there are a couple of odd things I thought I'd check tho...
First, the keyboard backlight turns on and off at seemingly random intervals while open. Anyone else got this?
Also I've seen screenshots of the battery use screen showing how much power is used by each system. The screen always is at least 75% on mine, even when its been sat in a pouch most of the time with just a couple of messages or a phone call- this seems quite different to other peoples experience.
Is there any reliable way of benchmarking the battery to check? If not, does anyone fancy helping me test?
im actually suffering from the same problem,
i thaught it was because the first week i was using it lots thats why the battery wasnt lasting long, but on monday morning with a full charge ,
only with a few calls , texts and checking train times on TFL , by the time i got to sleep that night the battery was on 30%
I was shocked , checked the battery useage meter , everything was below 5% except the screen which was was on a shocking 80%
I Then formatted the phone , restored to default , removed everything ,
set the brightness to lowest useable which was just above the 'o' on 'ok' in the brightness screen let it charge to 100% for use on tuesday.
Tuesday - Morn before i left for work it was on 100% , the only thing i had setup on it was email, brightness on low - but useable .
Screen must have been on onliy for 20 mins throughout the day
Got home , battery was on 45%
battery useage - again display was taking over 70% of it when it was hardly on .
I am RMA'ing this one tommorow
I think its an issue internally with something shorting on the display, battery shoudlnt be draining that much if its not on
Out of interest was yours a UK Desire Z ?
Yep. This sounds exactly like my situation in every detail. I couldn't believe reports from other people saying their batteries were at 92% after 12 hours- even without using mine at all this wouldn't happen.
Mine is a UK desire z, from play.com. I think its over 14 days so RMA might be tricky, although I know I have lots of rights thanks to distance selling regulations. Hope I can exchange without too much fuss.
Ooh, just thought of something. When I set the brightness really low on mine (below 20% or so) the screen flickers slightly. It's most visible on a totally white page. Does yours do the same? Faulty backlight maybe?

Just tested mine, definitely no flicker.
Now my experience with the battery....
I play about half hour - an hour of games every day, plus about up to an hour wifi, using the xda app throughout the day using data, 10 - 15 txts and a few 1 - 2 min calls... Not too heavy usage.
I'm getting 30-36 hours, I'm happy....
BUT..... I have not plugged in through mains once yet. I read that charging through USB gives better performance... so far that is looking true.
I got the same kind of time out of my Hero using mains but that was with zero game time.
yes! pizza65 , i noticed the flickering too! , i thaught it was just my eye being twitchy ! Noticeable on internet browsing on low brightness! .
Mine was from handtec .. (amazon delayed too much) so changed last min,
it comes with a 2 year manufacturer waranty i think so even if you take it up with HTC direct they should be able to help if play dont.
I tried a diff radio and rom , but it made no difference.
Maybe the UK batch is still faulty , wasnt that the reason why it failed google testing and got delayed for release here?
Whats your hinge like ?
ddot what network are you on ?
same to you pizza65?
im on 02 , i dont think it is a network radio issue with switching of hspda/3g to 2g signals as it does say cell standby battery useage is around only 6% , but then again the phone could be false reporting

Not really if you want realistic real-world results with data connectivity etc. It varies too much since everything counts like signal strength.
You can always just turn off everything and burn the battery with a movie but first thing you should do is a few dozen full discharges before you do anything. I've noticed that HTC (and other manufacturers too) pre-use their batteries ie. charge and recharge them until they're optimal for consumers, hence the whine about bad batteries when people buy new phones (and in reviews as well).
I'm on Orange, I don't think its network because, as you confirmed, the "battery use" screen says that the screen is draining all the power. If nobody else gets a flicker on low brightness (it can take a few seconds to see it, but once you notice it...) then it looks like our screens are the culprit. Maybe.
I've deleted batterystats.bin and fully charged, so ill give that another chance before talking to play.
Ddot, what percentage of the drain is from the screen on your z? Also, if you press 'display' in that menu it will say how long the screen has been on, what does it say?
I have the same issue with battery performace. I've moved to Desire Z from my old Desire which had AMOLED display. On my old one, the display taked 5-8% of battery. On Desire Z I have minimum 50%, but ussually ~70%.
After reading that some people can use their DZs like "for two days of heavy use (gaming, browsing)" or "5% for 6 hours" I can't understand how?
Comparing to old Desire my DZ have poor battery performance. But the specs tells it must be much better.
I'll publish my battery usage stats after some days. Maybe it'll be useful.

Very interesting, thanks for sharing
And a really "geek" method here quoted from cyanogenmod issue:
Comment 27 by david.j.erickson, Aug 19, 2010
Now, I was still having abnormal drain on my battery. As suggested in the Wiki and also confirmed in another cyanogenmod post, clearing the battery stats can help. I followed this procedure:
Fully charge the battery, says Full and 100% under Settings - About phone - Status.
Reboot into recovery, wiped battery stats. Phone still plugged in at this point.
Reboot into rom, checked to make sure battery was still Full and 100%.
Unplugged phone.
Killed it, used Maps on Wifi and messing around. Killed it in about 3 hours or so.
Tried turning it on a couple times to make sure it was *dead* dead. It still tried to boot, but couldn't complete without shutting off.
Plugged phone in, booted it up. It may be better to not turn it on until it is fully charged, but this is just what I did.
Let it charge overnight, next morning took it off charger since it was full.
I have noticed pretty good battery life since doing this. This morning on my bus ride in I pretty much constantly played some Storm8 games and used Listen with Bluetooth, was only down to about 82 or 84%, can't remember. This is on par with previous CM release for me.
Not sure why this rom in particular had so much worse battery drain out of the gate, and not just for me. Fortunately it seems correctable. Maybe if a few of you could give this a try and see if it improves your battery performance we could conclusively say battery calibration is the solution.

What about the flicker? Can anyone confirm that?
I have a UK (read: QWERTY) Desire Z, first batch.
I tried reprodocuing the flicker by lowering the brightness completely and looking at a blank white page in the internet browser. Couldn't see it. Maybe I wasn't looking hard enough.
That said, I'm not getting the great battery life that most seem to be getting, and the stats always show the Display as being the number one drain. HOWEVER, it doesn't seem quite as bad as you guys are saying.
Right now, it looks like this:
Unplugged for 18 hours and 16 minutes, battery at 36%
Display accounts for 41% of the drain
It has been on for 50 minutes.
(stock ROM, running an IM client 24/7, synced to three email addresses... Typoclock seems to use 2% of the battery every time as well, which seems relatively high for such an innocuous little widget)
Yeah. I have some slight flickering too, slight when low light set.
Uk stock.
I dont think high display percent is an issue too much reading cyanogen issue comments.if you use nothing but low cpu burden apps, display should eat most.
Also if i have it off, power is eaten by cell standby.
Im still hoping for a settled battery log mentioned in forums.
My 2 cents:
If I "use" the phone, I have to plugin it every night.
If I do not "use" it (nobody calls that day, no browsing or GPS (Just work!)), I plugin it every two day (ex. mon - wed - fri).
The display is always 65-80 % of the "drain problem".
Today the stats are:
7.30 am: full chargerd 100%
7.30 pm: display drains: 70% in 1h : 21m - battery at 20%
I leave automatic background gmail sync on (only daylight, I use the "Flight mode" overnight)
No bluetooth, no wifi, no gps, brightness 35-40%

No phone either.
I'm on a North American Desire Z and I see the display using 70%-80% of the battery when I have the display on for approximately two hours out of the day. I keep my display quite dim too, at 20% brightness.
I'm also running everything stock. No root, no custom ROMs, no anything.
Isnt display percentage actually the display driver cpu time eaten?its just a theoretical value isnt it, not watts gone? It seems obvious that its eating a lot as it refreshes all the time regardless of display light level.
My screen on is only 33% today, im sure its usually higher though. Maybe its due to me flashing stuff all day. Ill do a full charge tonight and report back Sunday.

Hi,
On my One-X battery meter is completely inaccurate. Sometimes it sits for hours on one value (e.g. 90%) and then suddenly drops (with no CPU/data activity whatsoever) to for example 80%. This results with very jerky battery use graph (attached mine). I am on 1.29.401.7 and done multiple full discharge/charge cycles, but it does not make any difference.
I have never seen such bad battery meter behavior on any other Andoid phone. Have you got similar problem?
I have the exact same problem actually.
Same here. It's as if it doesn't update the battery meter when it's in sleep (fifth core running). I suspect it's because of the T3 architecture and power management. As soon as you wake it, after maybe a minute, it updates the battery status...
Mines does it. Can sit on a %age for an age then with little use it will plummet.
@Op,
No I didn't notice such a problem on a unrooted One X and with no modifications running the latest OTA update 1.29.401.11.
Did you play with battery apps or did you modify something yourself which could cause this issue? Did you investigate what could cause it?
How long do you have your device, did you install apps? Can you provide more info about it maybe? Do you softreset your device?
Did the problem exist when you bought the device?
Thanks.
So it must be general problem then. It happens to me not only in sleep mode, but when browsing the web, etc.
I think these sudden percentage jumps and meter inaccuracy also contribute to all these battery life complains from various people. I was personally shocked when after a few minutes of web browsing battery dropped instantly from 30 to 20%. It looks like crappy battery, but in fact seems to be just dodgy meter...

I have got the phone for almost a week now and I am pretty sure this problem has been there from the very begining. I initially though this is because a couple of full charge / discharge cycles are required to calibrate the meter, but it did not make any difference. My phone is not unlocked, no mods or battery apps. I did not try soft reset though.
It looks to me that meter is somehow not updating during the sleep. When device wakes from sleep, after a couple of minutes value drops significantly. This problem is probably a reason for various false claims that One X does not consume a single percent of battery during the overnight sleep.
Yeah, i have the same thing. Sometimes my battery drops about 2 or 3 percent at once, sometimes 10 percent...pretty annoying.
Thanks for your reply.
I'm new to Android but I do have some Windows Mobile experience.
It's weird to me seeing people having such problems because I realy don't experience it.
My battery meter is constant, also after a night sleep.
Maybe it's because I use my device different as others I don't know, it's strange to see all these reports in XDA forum as the One X to my opinion is a very cool device.
Maybe you could try some battery percentage apps and see if it realy is that insufficient?

I used your excellent ROMs on my HD2 in dark WM6.5 ages . I am glad to see you here with One X!
I installed Battery Meter Widget and (if the readings are correct), my One X consumes about 10-15mA during the sleep with Wifi and 3G on. I will keep an eye on the percentage.
Don't get me wrong - besides of erratic GPS and dodgy battery/power management problems, I really love this device.
I really wished that international One X version was based on S4 SoC (superb GPS with GLONASS and great power management as S4 is a 28nm chip). It is such a shame that dodgy Tegra 3 ruins this excellent device...
Hello, maybe this behaviour is only due to the voltage sampling/display ...
Someone here says the native battery app was only at 5% precision at display
and it looks like it updates in long time samples too ( 5 minutes ? ) ...
Knowing that Li-Ion goes from 3600 mV ( 0% ) to 4200 mV ( 100% ),
it means 600 mV of voltage variation from empty to full, with 1 mV precision.
So 1 millivolt is 0.2% of battery charge.
The display should be really more precise if all voltage precision was used.

looking at that screenshot you have posted the sudden drops appear to be perfectly aligned to the 'screen on' or 'awake' periods so the most likely (and obvious) cause is that using the phone causes most battery use. I have seen this with many phones, I think its normal. Being in standby doesnt use much power at all but lighting the massive 4.7" screen and running a quad core processor does, so when you use the phone it uses loads more juice... thats my analysis anyway

No, this is different. Drop in fact seem to be related to wake up from deep sleep, but the point is that this drop is massive and instant i.e. battery instantly drops from 30 to 20, bypassing all other percent states in between. Also, I am sure battery state does not update properly in deep sleep in many cases. At some point I left my phone for almost a day alone (wifi, 3g, Gmail and exchange sync, etc) and it did not lose a single percent, but as soon as started using it I observed instant 20% drop.

And I have even worse problem, can anyone help me?
Take a look at my thread (not highjacking yours, just want some help too), my current widget never reads a real value AFAIK.
It stay with -850 for more than an hour at times...
And my battery life is dismal...
So this means that seeing no battery discharge throughout the night in sleep mode isn't due to excellent power saving feature of the companion core but is in fact poor battery meter?
And yes, my One X shows fast and huge discharge (3-5% at once) when I use after being in long sleep mode

I think it too. Phone on sleep with data and sync on for 1 or 2 hours and % don't change. Use it for 2 min. and it suddently goes down by 5/10%
In my opinion the battery meter lacks of accuracy. This brings to inaccurate real time current calculations and wrong information about what's consuming power when we use it. That's bad!
I'm also seeing these big drops. For me it seems to happen between 100%-60% battery, battery level will drop anything from 5%-10% chunks at a time. After 60%, it does seem to be more stable and drop in 1-2% increments.
I've recalibrated the battery through CWM a couple of times but still get this issue.
It almost seems like there's a bug in the code that is causing the fuel gauge to not update.
I can tell you this, I modified other HTC phones battery driver. The nexus one driver for example updates volt, percent, temp, every 50 seconds while the screen is on. When off the sample poll changes to 10 minutes per update. This is real easy to see in the driver code, and you can filter dmesg log for "batt" and see the time stamps do in fact match this.
But the one x looks to be getting hung up on that part. Anyone know if kernel code has been released yet?
My wife and I both got new Verizon Galaxy Nexus phones about two weeks ago. Having heard of the poor battery life, I immediately bought an official Verizon extended battery; wife stayed with the stock one. After both of us set up our phones and went through a few charge cycles, I noticed something odd: while her battery would last 24-36 hours with mid-level use, mine would die within 9-12 hours with minimal use (it has never made it overnight).
My first thought was that some widget or app was syncing or otherwise waking the phone when it shouldn't, so I removed all the widgets from my homescreens and disabled all syncing but Gmail, Google Calendar, and Google Contacts. I also turned the screen down to minimum brightness. Still had the fast discharge issues.
Next step: uninstall all apps that I've downloaded. Battery still drains too fast.
Finally, I did a factory reset of the phone, and did not download any new apps. I thought maybe there was some deeper setting that I had overlooked that was causing the issue. After the reset, the battery had its worst performance yet at ~9.5 hours with bare minimum use (mostly overnight). Wife's phone was still going strong with about 34 hours of usage.
I am in wifi coverage all day (except when driving to/from work), so I have kept that on. Bluetooth and GPS have been off the whole time. Average time without signal is ~2%. 4G is also on. I also tried 1-2 charge cycles with the regular battery to make sure that it wasn't just a faulty extended battery, but it predictably resulted in even worse discharge time.
I have kept track of the battery usage stats both in the standard Settings as well as Badass Battery Manager, but nothing has seemed out of the ordinary. Right now I am charging up my wife's standard battery in my phone, and she is using my extended battery, to make double sure that I didn't just end up with two bad batteries.
Both of us are using stock ICS 4.04, and are not rooted.
She uses her phone for Google Talk, Facebook, Tamadroid (Tamagotchi app), etc. throughout the day (don't have more exact usage stats at the moment), while mine has been sitting practically unused for the last few days while I try to see if my various steps work, so the top drainers have been (in order) Mobile Standby, Phone Idle, and Screen On.
Last night when we went to sleep, my phone was at ~70% on the extended battery, and hers was about 14%. This morning, mine was dead and hers had 5% left.
Is there anything else I could have missed that could contribute to this issue? Unfortunately I do not have access to to my actual usage graphs/stats right now, or I would link them. Any help would be greatly appreciated. Otherwise, it's back to Best Buy to exchange for a new phone.
UPDATE: This was a hardware issue. Exchanged phone and saw immediate, drastic improvement. See my last post for more detail:

It sounds like the battery to me. Not all batteries are created equally. The quality of the components is going to directly lead to the discharge rate, degradation over time, etc. It sounds like the battery you were sold sucks and the stock one would probably work better.
I certainly can't think of anything else you can try. It would seem that swapping batteries with your wife for a day would tell you for sure if it's something to do with the phone or the battery.

I am going to swap out the battery at a Verizon store later tonight, and see if it works any better.
To make a better comparison, compare screen usage as it is the big eater of the battery. You should find it on battery usage.

Its hard to say why.. but is there anything wrong with the network on your phone? My brother got one, his dropped signal every 2/3 minutes and the battery lasted at least 4-6 hours, you can also check to see what your phone is using in the battery section in settings.

Got a new extended battery from Verizon, and it seemed to be working a lot better during the day. However, once I went to sleep the charge dropped like a rock! I am doing a new charge cycle with Badass Battery Manager watching over it, and will post pictures when it is done. I have no apps other than fully updated stock apps and the battery manager. This is incredibly frustrating because my wife's phone is not experiencing any issues overnight. It is looking more and more like this is a faulty handset...
Got some usage stats now. Here is the first full cycle on the new extended battery; seemed pretty good at about 1d 5h. Unfortunately, it has gone downhill from there.
looks like your phone was working for a signal alot of the time.
Here are the results from the next cycle; there is already a noticeable drop to just over 22h.

yeah you have terrible signal. your phone is trying to push for a better signal, which causes more power drain.
if you look at your signal graph, you hit red signal, which is near dropped signal range.
This is from last night. After letting the battery completely discharge, I recharged it while the phone was off. It hit 100% around 12:30AM, when I went to sleep. Fast forward to 8:00AM, and the phone has discharged 66%! Obviously, I was not answering calls/texts/etc. during this time.

Yup, he seems to have a lot of horrible coverage in his area or his phone is in a terrible spot where there is hardly any signal.
Test your phone around your town or home.
Your signal should pretty much look like this
I'm usually full bars, rarely do I drop below to three.
If it helps, disable 4g until you need it.. it will saviour some of your battery.

This makes sense, but for that my wife's phone is usually in the same general area and is getting significantly better life. Could the signal difference at my work compared to home really cause that big a discrepancy? I am usually at 3 bars, according to Phone Radio's settings. This would also not account for the massive overnight drain that her phone does not experience 6 feet away.
I installed Badass Battery Monitor and CPU Spy on her phone for comparisons; I will check her signal levels when I get home.

Well I hope its not a hardware issue on your phone.
I've seen way too many people having this issue recently.. .My literally only issue is my screen, its covered in tint. Yellow, red, blue, purple :/ funny I get a perfect hardware phone and get a ****ty screen. Not going to return it to take chances.
Its possible you may need to update your radio - depending on it, for various users it has different effects on battery life and signal.
Anyway looking forward to the results.

The radio would affect the "time without signal," right? Last night (66% drop in ~7.5hr) it said I was without signal for 4% of the time.

Someone correct me if I'm wrong but.. the RADIO should help or make your coverage "signal" worse. If its hardware or just horrible signal the % loss should be a lot higher with normally about an hour of screen on it should show around 20-40% signal loss.
Normally signal loss is around 2-4%.
I would keep an eye on your signal bar "on the status bar" if it drops - plummets to an empty bar with an × then its possible you have a hardware issue. If it don't drop or if it does check the signal loss occasionally to see how much is lost.
If its horrible signal I do suggest a new radio to help you, if you dabble in the radio world.. please read carefully on them. They can cause serious issues if you get a bad download or wrong download "md5 mismatch". At the least harmful it can boot but without any type of signal etc.
Its easy to use but can be dangerous to your device if not handled properly

Mine is 4% loss also. I've never noticed any significant differences in battery life going from the cornfields to the city.
This phone is known for radio issues. It's pretty disappointing but I've just grown used to it.
Which radios are you currently on? Settings, about, baseband. Should say fc04 fc05 if you're on the latest.
Some people have better luck with different radio combinations depending on their phone.
From your battery Stats its like you barely use your phone. Could you show a screen shot of cpu spy?
Would you consider a different rom and kernel?

Assuming you mean me, give me a few hours? Gonna throw on a full charge and wear it down. I'll give my screens of my phone when its near dead, I heavily use my phone. I'm surprised I was on 2hours with half battery after watching videos.

I have the same baseband as this image. I just added CPU Spy this morning. I will add some screenshots of it after my next full charge cycle.
If it is a faulty radio, would it be in my best interest to exchange the phone at Best Buy? I have about another week to do that if necessary.
I'm having similar issues, although it doesn't seem as bad. I'm going to take the chance of exchanging it because I also have 4G dropping issues, because like you said, we've got a week, and I'll exchange the phone as many times as I need to until I get a *new* one without any issues.
Kind of disappointing, my screen seems great.
hey guys
I'm new to GNex (3 days user here )
my nexus has a serious battery drops when it reaches to 40% on every roms and kernel!!!
it is like this that when battery percentage is under 40% it drains super extremely fast even w/o any usage to nearly zero ( in about 20 min ) of course some times it even does not get to 20% and phone shutdown!!!!!
i also calibrate battery but no success .
( my battery usage above 40% is normal and i get nearly 3+ hours screen on with moderate usage but it sucks below 40%)
any help/suggestion/etc is welcome.
thanks in advance
edit: screen shot added
**********************************************************************
i notice several nearly same topic but no one exactly mentioned to my issue so i created a separate thread
sorry for spamming
Do you have consistent network signal throughout the day? Just saying as 40% may have been reached by the time you get back home, for example.
Have you checked if your phone wakes up too often - triggered by some application?
(Further to above example, perhaps some location based applications starting up?)
A screenshot of battery usage would be nice.

as soon as my battery get to 40% period i'll take screen shots
thanks bro
screen shots added to the OP
any help? solution?
When you say you "calibrate" your battery, what exactly do you mean? If it's wiping battery stats, that has nothing to do with anything even remotely related to battery charge or indication.
From the screenshot you posted, it looks as though your screen is constantly on. That's another tangent, though.
You'll need to try a factory reset, but be advised you'll lose your data. If that doesn't fix it, then you're likely looking at a bad battery.

It really bears mentioning that there's no user calibration of the battery. Anyways, if this is happening regardless of rom, then you're looking at it being defective hardware. You'd want to first try a new battery. If it still exhibits the same symptoms, the problem would be the phone itself.

You could try and rest the phone (switch wifi off, screen off and keep phone unused), and see if the drop is still drastic after say 50%.
Tried the ZenSeries v8/9 too? I had good battery times with that, close to 4 hours screen time with 25% remaining.
Do check what month the battery was manufactured on, and if it's a recent manufacture month, it may be faulty.
I have the same problem too with my Yakju. I am using stock ROM updated to JB 4.2.1 manually. Battery drops dramatically from 40% when sitting idle.
First two days I had the phone it had great battery. I was getting 16-18 hours of life with 4-6 sot. Now the last two days at work it's worse than my op2. By the time I got home yesterday I was at like 35%. Previous days I was well over 60.My android system is taking most of the blame. On my good days it was at like 8% when the phone would die. Right now with my phone at 79% it's already at the top with 5%. I've barely used the phone while I'm at work right now. It's been unplugged for 3 hours and my sot is 35 minutes. Not sure if it's got something to do with the ambient display. Maybe finger print scanner. Any one have ideas?
Download gsm battery monitor, are you rooted?

Seems like you had been on LTE for quite long. Mobile data takes pounding on battery life. You will always see android system, android os and Google services etc on battery stat when using mobile data. Not the same case with wifi.
same here
i have mixed net usage with m,mostly lte on and wifi
can anyone have its quick fix pls report asap
i have greenified many OPservices but it didnt helped

Not rooted yet. Didn't want to loose dash charge with a new rom but cat just chewed the cord so guess I'll make a jump. Is that only a rooted app?

Humm I thought it was the other way around. Nevertheless I have WiFi at work. Can't remember if I was on it though. I'll have to test that out.
You don't have to run a custom rom or loose dash charge cause your rooted. I'm still using stock oxygen 3.1.3,and have the basic functions like dash charge working. I'm not sure if you have to be rooted to use gsm, cause I'm always rooted, but it may gave you more specific insight as to what exactly is draining your battery quickly.

You know the image you attached, with the graph on it? Tap that and check the Awake heading. Is it one long solid blue bar? If yes: your phone stays awake (doesn't go in deep sleep mode). Does restarting it make a difference (i.e. does the solid blue bar get broken up)?
The problem emerged on my OP3 as well yesterday AND I had it on my prevous phone (a OPO). On the OPO the problem was that it wouldn't release a wakelock that kicked in during charging. While I haven't explored the problem on my new OP3 enough to know if this is the same problem, here's what fixed it for me if the problem is indeed charger related: when charged to your liking turn off your phone with the charging cable still in. Once turned off, remove the cable and restart the phone.

I'll have to check that out. I'll root today. Just haven't had a need with the OP3 I'm digging this version of oxygen and not missing any of my root abilities. Also I use android pay. But I guess I can live without it lol

Are you talking about under history details? I'll check tonight once my phone is drained. I did a battery cycle yesterday. Let it die and charged to 100 while it was off. We'll see how it goes today. And your saying it was an actual charger problem?
Heavy battery drain might have to do with the "pocket problem". The fingerprint sensor constantly activates and is not properly blocked by the proximity sensor.
There are several threads and posts about it, here and on the oneplus forums...

Yea I had that once in a while with my op2 I'd take the phone out of my pocket and it would say too many attempts at the scanner. Nothing on this phone like that though. And of course today is a different story with the battery lol its good today. So maybe it's while I'm at work. Idk it's odd. I need some more testing. Currently I'm at 9.5 hours on battery with 56% left and almost 3 hours sot. I'll see how this week goes at work and see if I can diagnose anything
I've been having this problem as well, losing as much as up to 20% of battery overnight, while it was doing absolutely nothing. I've tried a couple of things, but last night it 'only' drained 5%, betterbatterystats reports 0.6% of drainage per hour.
I think this is due to the weather option in the launcher, could anyone else try turning it off and see if battery life improves significantly?

You don't even need to do that. You can just check it after an hour or even less. Just put the phone away for an hour with the screen off and check history details.

Not quite. I'm saying it was a wakelock that kicked in during charging and that wasn't released when I took the phone off the charger. I don't know if it was the charger caused the wakelock.
Great for two days now I'm leaving work with 45% battery and only an hour and a half sot. Unplugged for 9 hours. Idk I feel like it's hit or miss
