Battery Issues On The Lumia 950 - Microsoft Lumia 950/950 XL

So i decided to switch to Windows phone just to check out what Microsoft has to offer. Turns out the platforms quiet great except for the the fact that the battery life sucks (Lumia 950), Ever since i got the phone the battery life is not satisfactory also tried to flash the firmware with WDRT it did not really work out (the battery life is same).
I have been checking the windows forum with similar complaints but there aren't many threads that have been discussing the problem lately.
So the question is , Are Lumia 950 users still facing the battery issue? . And also if anyone has come up with a solution to fix this issue.
PS: Most of the features like glance, hello, start screen have been turned off. And background apps have been disabled with power saver turned on
Thanks For Looking Into The Thread

Lucky you !
Whats your say on this?
Should the battery be replaced?

maybe is not battery. maybe some hardware cause battery drain problems

Mine is working good without battery issue, running the latest CU win10

[Q] Battery Issue

Hello everybody,
I just bought my Flipout thought the design was kind of funny !
I am quite happy about it except the screen resolution (but I knew it before the purchase)
I need your help :
after a full charge I run out of battery after two hours of use (not standby), could you eventually help identify what is wrong ? is it because of the apps running in background or because the battery capacity is bad ? (or both )
The apps I am running: nimbuz, gtalk, several mail accounts, that is more or less it.
Another point, I have noticed that on heavy loads the Flipout becomes an oven, have you experienced the same ?
Many thanks for your help,
Bao

Nimbuz eats battery like there's no two hours from now.

The other half uses this phone
had the same problem
after a few hours the battery died completely.
I turned off the happenings rubbish and the facebook stuff and everything seems fine now
sadly i cant install any battery monitoring software to work out what was really causing the issue
(as i've actually turned off most stuff on the phone now apart from background syncing)
battery seems fine now
Personally i believe the problem was the whappenings widgets on the home screen and the battery conditioning
Hello
right ! I suspect the data exchanges could be the reason
we could also diminish the frequency of 'mail checking'
I was actually thinking of getting a second battery or making a usb charger with AA batteries for this, something like that, so I could use it how I want and extend battery life

[Q] Need help figuring out how to improve battery life of my HD2!

Hey guys. sorry if theres a thread like this already. im new to this forum and searched for nearly 3 hours but didnt find much of what i was looking for.
i have a t-mobile 1024 Hd2 with a custom windows mobile ROM LEO_firestorm_v7.4.23135-FX
and a android ROM (installed to SD)
mattcfroyo 1.5
and i also have setcpu installed. the phone(and both rom's) work great. the only issue is the battery life. my phone even when i would barely use it would maybe make it about 12 hours on a charge(doing very little web browsing, turning wifi/ bluetooth off when not in use, brightness around 30%). what have you guys done to get better battery life? should i install different ROMS? is there a WM rom that is basically barebones so it takes less resources and improves battery life? i dont care what the WM side looks like as i only want to use android anyways. i want to use Android as my main OS and how should i setup setcpu? really sorry if this thread is a repeat. if there is another asking exactly what i am please give me a link. im very new to this, so guides are very appreciated aswell.
i did find the thread "HOW TO: Wipe Battery stats to improve battery life" and ill be trying that. what i mainly want to know is how to guys have your roms and setcpu setup.
links to better roms/guides etc. are very appreciated. thanks allot guys.
any rom needs to be compatible with the 1024 hd2 though.
Hi and welcome to XDA,
I've my phone set up as shown in my signature. I don't use bluetooth, basically have no calls, some texts and fairly heavy browsing (web, tapatalk pro, newsrob pro) when I'm on the train. I have a 3mA-5mA drainage in standby. My phone will last 10-12 hours on a charge, after which I have to plug it in. I'm kinda used to it now, but last week I thought I'd give UltimateJuice a try. My phone lasted a little over 17hrs, though I probably used it a bit less intensive that day. The days after I got about 14-15 hours a day with regular use.
I have JuiceDefender installed, which also manages cpu speed. Basically it allows the cpu up to 614 Mhz when the phone is sleeping and 1190 Mhz when awake. Screen brightness is set to 15% currently. When I'm at home, JuiceDefender switches WiFi on automatically, when I'm outside it connects to 3G every 15 minute during 1 minute (adjustable).
Drainage is still somewhat heavier compared to WM, but I can live with it.
Sincerely,
Mac
looks like i found a solution today. last night i underclocked my cpu to 700mhz and i have not seen any performance difference and the battery is lasting allot longer. i have been using it moderately and the battery has gone down 8% in 3 hours of use which is already allot better than before.
i checked my battery power and after it was fully charged it showed 4.2mah so i knew that wasnt the problem. does anybody have the problem that their contacts(in android) are removed if they soft reset their phone? and if so does saving contacts to sim work to fix it? thanks

backup everything before you do this though. it's known to cause crash at startup and you won't be able to use your android again.
im having a problem with my hd2. i made a call today. and all the incoming voice sounded like a decepticon. kinda cool but definately not useful to actually talking to a person. what should i do to fix this? is it the rom i am using?

HD2 HUGE BATTERY DRAIN 1% every 1 minute

Hi my hd2 is on a stock windows mobile rom and has a huge battery drain, every 1 minute or so i lose 1% of my battery and even on standby its the same.
Please can anyone help!!!! I have just flashed a stock rom from sd and have nothing on it and it still does it!
did you flash another radio rom? battery performance has a lot to do with it.
formatting your sd card could also help.
I've tried formatting my sd card and have tried flashing many radio roms right now im on the latest one (2.15...) and still it does it.
well the latest doesn't mean that it's the best for you. it depends on your carrier and area. but this wouldn't result in such a high battery drain.
sorry i can't help you then. i would try to make a freash install with task 29 and everything and if it's still not better try another battery.
Ive tried everything..no one knows anything about it
Thanks anyways
Would appreciate if anyone else has this problem too?
Sounds more like your battery is on the way out. Do you have another you could test?
Yupp, i have 3 standard htc batterys and 2 of them are brand new and still it happens
You did not say how long you have had the HD2, whether this problem has occurred from the beginning, or had just recently started. If it's been that way from the time you got it, it needs to go back to the vendor/seller for replacement. If it has suddenly started, what has changed? Other recent threads here note that a change in GMail was causing problems with high CPU levels and fast battery drain. I believe you said in one response that two of your three batteries have this problem. I assume that one of the batteries does not. If so, it sounds like bad batteries.
Sorry i meant to say that every battery that i try, it still has the problem. And also i brought this phone (used) with no problems and i put android on it, one day it turned extremely hot whilst i put it on charge, then what used to happen was whenever i left my phone on standby (screen off) my phone would switch off. But then i changed my charger cable and that problem was fixed but now i have this problem.
In that case could be the cable not supplying enough charge to the battery, or the phone reading battery stats incorrectly. Other than that I'm at a loss.
Tried everything :/
Thanks anyways I guess its just time for the bin :/

Are you using Gmail? There have been a lot of reports about overheating and battery drain from gmail accounts. Evidently there was some change in the way Google handles their accounts.
Nope, not using gmail
theres nothing on my rom as i just flashed it.
if you flashed it new and the problems started at this point you can try to wipe the battery stats in cwm. don't really now what exactly that does but it's worth a try.

thats providing hes running it and not using a stock winmo 6.5 rom
Yeah, im using a stock windowsmobile rom so no clockworkmod unfortunately..
oh right. there was something with windows on this phone ^^ sorry already forgot that.
Hi, did you try the following?
Switch off the phone completely and then remove the battery for approx. 15 to 20 seconds. Then put it in again and start the phone.
When I used this procedure the battery drain was normal again.
BR rainer
tried that still no luck :/
Take out the sim AND sd card. Maybe one of them is going bad.

Poor battery life after Mango.

With Nodo my LG has battery life little more than 24h, even when heavy used for gaming, email or internet. Mango version used almost exactly same, has battery life about half of it, and after 16h is totally dead. Turning on batery life saving in Mango does not change anything. I have open-marked phone, and to download mango I had to full flash old european firmware and upgrade to Mango. Any comments or solutions?
I noticed the same, battery drain is going down much faster then before.

The same happens on my LG
Double wattusage
This is common, I too have experienced this.
I am trying to research the issue.
I got worse batterylife after the pre-update for Mango, where they altered the speech quality and touch sensitivity on the phone. I am assuming this is related to the radio in the phone, so I've ordered a new SIM card to rule out my dated SIM card for the phone.
If you search twitter for mango and battery, you will see that 50% of posts quote better batterylife with mango, so I'm assuming this is a firmware issue from LG, and not a mango issue.
Anyhow, early tests showed E900 using 1,3watts to playback a video, while the iPhone4 used 0,7...
Also the iPhone4 manages 40 hours of music playback. I'm lucky if I get 7-8, might be due to three different apps showing up in the app-switcher when playing a podcast. The music hub start screen, the podcast list and the podcast itself. Should be just one instance...
Will post back later.
Reset your phone
By factory resetting after Mango installation I went from 0 days and 12 hours standby time, to 1 day and 16 hours.
So there is something messed up in the Mango deployment that causes batterylife to be cut in half. To bad.
The same thing
So you recommend. To factory reset or reflash and than install Mango again, don't you?

It worked for me.
I just tried it two days ago, it seems better, but this will be the first day without having a charger handy. So, I'll post later if it actually helped.
On the bright side, setting up the phone again was a snap. Reloading the programs was the slow part, because you had to navigate from the "receant purchases" on your account to find the programs you had installed.
Not for me.
I've even reflashed from StarHub to European Open today.
Nothing changed.
I'll check tomorrow if something will change.
What is your batterytime in batterysaver when fully charged? When going to google mobile search, do you get the featurephone edition or the touch friendly for advanced phones? If you change the language for typing does it work or does you keyboard stay the same? These are all errors I had before.
I waited for my official Vodafone mango deployment, and after it was installed I 100% reset my phone in settings dialogue. No funky xda installhax0r stuff.

I have none of the other issues you descirbed... just the battery life issue. If either changing push email etc doesn't make things better, or I see a few more people saying that a reset helped them, I may go the reset route. Hopefully that doesn't need to happen... seeing as I chose WP7 and not Android so that I could avoid issues like this.
I started thread at MS Q&A

After a factory reset it seems that my battery drain is back to normal. So, for me it worked
Is there a big difference after the factory reset? Does it worth to try?
I am facing this battery drain issue too. Battery falls down by 14% overnight in standby without data connection or WiFi. Factory reset didn't solve the problem. Any solution?

I had big battery drain problems after mango. now it seems to be more stable. anyways, I think it might have been some kind of program, running under nodo intructions, like facebook, maybe some compatibility issues, I dont know, I only know that after updating all the programs I have to the oficial mango version, battery is doing better. not a lot better, still crap, but better than before!
The factory reset thingy worked for me as well , now I got about 2 days of battery instead of a half day
I have about a week if i use it as a phone only and one day if i use everything.

BUGS & BATTERY USAGE on JULY official rom

hi MI A1 owners.
for those brave enough to use the latest vanilla, official OTA rom, what change did you notice?
does the battery still suffer huge drain that appeared in 2018 roms?
it's a big "NOPE" for me to update, i'm still on official DEC rom because of this drain issue.
Battery life is good on 8.1 no issue for me getting 5-6 hours SOT on gaming.
Never had battery drain problems. Only "issue" is notification led not blinking.
Just noticed that led light is no longer blinking when notifications arrive. Light stays on only when screen is off. Also Bluetooth is constantly disconnecting.
Ambient display isn't working for me.
Led notifier is also not blinking anymore!
Led not blinking, proximity sensor doesn't work properly all the time, some scrolling lag. That's what I've got so far
dudes thanks for your answers.
i'm just more convinced to not doing the update.
maybe the drain i had was magisk-related. (?)
Nothing for me, even got ten hours of screen after some cycles. Led doesn't bother me and it's the only thing i noticed.
Yes, the LED is always on, which is annoying, but the bigger issue is there is no change in the battery drain. I charged to 100%, set the phone down and did not move it or use it overnight. 8 hours later almost 14% of battery was drained. I have tried everything I can think of to try, including turning off high accuracy location, not allowing any location things like safe area, etc. and still I get this drain even when the phone is not in use. Android kernel and system consumed 85% of that usage, and System UI, Play Store and Phone Services accounted for 7%! SO basically, basic Android paired with the A1 hardware seems to be the issue and I don't know that there is any fix for that.
At one point, I thought an upgrade to the A2 was going to be a no brainer, but with the issues with updates being broken and this battery drain issue that nobody seems to be able to pinpoint and resolve, I am thinking I may not buy ANY other Xiaomi. It may be time to try something else because the only way I can get two days of battery is to turn on airplane mode when the phone is not in use!

Dunno what to say man. Mine is below.
2-3% at most over night.
And now it would appear that there is an issue with airplane mode.
I put the phone into Airplane mode at 2300 last night with 90% battery and did not pay attention to it. This morning I turned to phone on to find there was only 69% battery left, and WiFi was working. (see screen shot) WTF???? I have started using airplane mode to keep the battery drain to a minimum when the phone is not in use, and now it would appear that this doesn't work either.
I am REALLY getting frustrated with Android and Xiaomi as it seems that every time they do an update, something else goes bump! I have gone from totally happy with the AI when I first got it to being ready to write off Xiaomi as a company I would consider for purchase.

Play services also cause these type of sudden battery losses.

Thanks for the thoughts, but unless I totally misunderstand what airplane mode is, WiFi should not be active when airplane mode is invoked. You can see by the screen cap that airplane mode is on AND WiFi is active. This seems to be a one off as it has not happened again for the last two days. I turn airplane mode on to stop the overnight battery drain while the phone is doing nothing. I have location set to GPS Only. IIRC play services was just updated 3 days or so ago, so it should have the latest version. I will check it and see though. Again, thanks for the thoughts.

I can't logically understand why you would think it is the hardware causing the issue. If it was hardware, what you are seeing would be happening to every owner of the phone and clearly that is not happening. By saying it is the hardware when you have other software loaded is akin to saying your car's air conditioning doesn't work properly when you have all the windows wound down.
There is something loaded on your phone that is causing the systemUI to be working when you think nothing should be happening. The first thing I see on the screenshot on your phone is that in the top left of the screen you have two non standard icons. That tells me that you have a skin or non standard software constantly running.
The way to solve any issue like this is to go back to basics. I would get the fresh rom and do a Miflash whilst keeping your data. Make sure you do a backup first.
If that does not work, back up your data and do a clean install and check the phone's battery life. Do not load any non google software / app at this stage.
Then each day add one app and test for 24 hours. You will find this issue and the offending app or apps and I would be willing to bet you a few Singhas it will be an app you downloaded not the hardware causing this.

Actually, I think it is a combination of hardware/software, but that is just a WAG. Others have noted the exact same issue without running the same software. My bet would be on the RCS services stuff.

Those icons are my Email client and GSAM Battery Monitor (presently 0.1% and 0.8%) and are the only two constantly running programs other than the stock apps and Sophos (0.3%). Neither use much battery compared to the Android stuff. Presently Kernel is 41.6%, RCS/Phone is 30.3%. SystemUI is 3.3%, Play Services is 2.0% and Phone Services is 1.8%

Good advice. I will do this when I have a few days to play with it. In the interim, it's airplane mode every night. Thanks for the reply. If it turns out to be one of these apps, let me know where to send the Singhas.
Good luck with it. I hope you find the solution. It can be frustrating, but getting to the bottom of it will be worthwhile. I haven't used Sophos for a long time and even then it was for PC. I am not up with how Sophos AV is integrating into Android but that would be my first guess.
I have only had one issue with this phone after updating and it was that the OS was constantly asking for a password on unlock after using fingerprint not just on startup. A clean install solved it and I have been trouble free since with every update. With over 50 PCs in my office, I could only wish that I had so few issues with Windows updates as I do with Android.
For me, night light auto schedule not working properly.
I can't tether via wifi/bluetoth/usb
Made another post with the problem.

Just for grins and giggles, I uninstalled my email client, GSAM, and Sophos, the only programs that run constantly other than system and Line. I then turned my phone off and back on, forced stopped Line, charged it to 100% and set it down with the screen off. It did not move of get used for 8 hours, yet it still used 12% of the battery. (see screenshots) This is better than the 20% with those apps installed, but still not close to what I would consider normal. When I first got the phone, it easily lasted 2-3 days between charges, with 6-7 hours SoT. Overnight would use MAYBE 2% of the battery. Now if I want it to last 2 days I need to turn on airplane mode overnight and then I can make it through a day.
So I guess the next step is to do as you recommended and load up the fresh rom when I have time to mess with it. At least I am now pretty sure that those apps aren't the culprits causing the biggest part of the battery drain. I hate to do it, but I am seriously thinking of a factory reset and seeing if that clears the issue. Would that put me back to Nougat?

So those apps were causing 40% of of the 20% of the battery drain. That is a good start. I am confident there are software issues with your phone. I see you have some GPS app on your home screen, if that was running askew, it might be constantly pinging. That is just a guess.
In things like this, work methodically through it. But of cause a hard reset would be the best way to go. I see no reason why you wouldn't stay on your current version after a hard reset.
If you want to go make to version 7 you would need to use the MiFlash program and a downloaded standard fastboot rom. You may need to do something else to the phone to go back to 7, but I would not think so.
