Anyone else experiencing excessive battery drain on their HD2?
I am interested to know if this is just my phone or if it actually just chews through that much juice.
I have had windows mobile phones for several years so I know all the basic ways to keep battery drain down.
Stuff that I have generally found:
1. If I keep the screen turned on without it going blank I lose about 1% every 2 minutes.
2. If I am browsing that figure almost doubles.
3. My old Touch HD used about 5% battery overnight when in standby but this phone will go through about 25%.
4. The phone gets really hot when browsing (much hotter than my old Touch HD)
I have tried flashing ROM's and Radios but nothing seems to help.
I am not running any software on the phone that I wasn't running on my old HD1.
I have only had the phone for a week so I am not sure if this is normal but I would be very surprised if HTC released a phone that lasts for only a few hours on one battery.

-1% every 3 minutes
-4% during the night (when i'am sleeping)
MAXIMUM : 45/48 HOURS

I wish I got 2 days
we really need extended battery ,hd1 battery was much more better.
Good mate but yes i agreee HTC has come up with a battery eating device this time around. My device on full charge just gives in around 8-10 hrs. This might be dat my EDGE is on and 7 mails accounts sending mails back and forth.
but truly i think that HTC better look into this very seriously cause more and more ppl are suffering in this battery drain..
Any of flashing roms and radio not helping either... did a complete hard reset but no step up
HTC come with longer battery battery for bigger devices soon......
The only solution i see now is get one of those extra battery worth mind bogling £52.87
I've had this problem ever since flashing to 1.66, I flashed the radio to 2.07.50.27 as this was said to solve the problem but it hasn't made any difference after a few days of use. My battery life used to be significantly better when I was on the original stock ROM, so much so I'm considering going back to it
I also know all the tricks as to clawing back the battery drain, my phone is idle on my desk at work most of the time and I don't use Wi-Fi, all the location stuff is turned off as are weather, stock and other updates plus my screen is set to 30% then off after 60 seconds. Despite all of that I lose 1% every 2-3 minutes
It seems to me that perhaps the radio is checking for reception pretty much constantly rather than say, 5-10 mins perhaps? This used to be a problem on my old Blackberry Storm but a few fimware updates solved it, eventually!
The only other thing I've noticed since the update is that once the battery drops below 50% or so, the drain seems to slow, I don't know if this is perhaps because the phone goes into some sort of semi-power saving mode?
Suggestions/hints welcome! I've had a semi-thorough look into this on the forums and tried most of the suggestions but still the problem remains. Will battery life improve after a few charges perhaps as this was a trait of my Storm's battery, the more you charged it the better the day to day battery life was (and no it wasn't because I had it plugged in all the time! Over time the general charge just seemed to improve when roaming).
Thanks!

You need to indicate what services you have running. Do you have any data services running eg: location services, push mail, weather? all of these have a bearing. In addition, network services can also drain a battery, especially if the signal is weak and the phone have to search for a transmitter, or 3g services.

That is a very interesting comment. Although since upgrading to radio 2.07.51.05_2 I have had very good battery life, I too have noticed a slowdown after 50%

Nothing is turned on, everything is set to manual.
As I stated I know all the basic stuff. I understand that all these things have a bearing on battery loss.
Everything I stated in the first post is for when I have nothing running. The phone is just sitting there running sense, thats all.
I have had my HD2 for a few days now. I am on Vodacom in South Africa.
I have not had a problem with battery life.
Yesterday i unplugged from the charger at 07:00. I spent about 1 and 1/2 hours of talk time on the phone, it was permanently connected to 3g doing weather updates etc. Sent and received a couple of sms's. Also played with a few tweaks and reboots.
When i got home at about 18:00 i had over 30% battery. I then surfed the web for over 2 hours to drain the battery.
try setting Network Selection to Manual

Same here with and without stock ROM.
yeah.. the phone is a battery sucker.... another cons of HD2....
This is very interesting to read because I do not have this problem. When I left my HTC HD2 on last night (I woke up at 4 in the morning to get something to drink and unplugged it) and then woke up at 8, it was at 98%. That means it went from 100% to 98% in 4 hours. Not to bad imo.
I am now at work and it is 15:34, and I am at 87%. I have made some calls, watched some videos, send a few text messages. Not much (I am at work so I got other things to do). So 08:00 (98%) - 15:34 (87%) - that's 7 and a half hours, with some calls, text messages and a video.
I am pretty sure when I get home at 18:30 the battery will still be above 75%. Then I connect to my wifi at home, refresh twitter, weather, browse the web a little bit, check e-mail etc. So that will drain my battery a little more.
But overall I have not had any problems with my battery life. I always make it trough a day, and never have a problem like 'damn my battery is almost done and I am not near a charger'.
Some info that might help:
I do not sync ANYTHING automatically. I still have some things to do with my Vodafone contract and do not have an unlimited plan yet. I only sync at home on my own wifi connection. For me this is not a problem, because I only need to refresh the weather each morning to see what the day is going to be like. Twitter I only do when I have the time. Stocks I do not use.
I have screen brightness set to automatic.
I am on 3G most of the time.
I am running the official 1.66 Dutch ROM.
I have some tweaks, games and programs installed.
I hope you all solve this issue, because it just can not be that my HD2 has a good battery life, and your HD2 not
Kind Regards
EDIT @ 17:00 still 87%.
I am in a 3G 2100 only network (I don't have 2G functionality).
ROM: Artemis 3.0
Radio: 2.06.50.23_3
Customization: Seiya 6.5.5
I don't leave any automatic updates on, except for my e-mail account every 2 hrs.
I never close my connection.
The drainage overnight is -3% (8hrs).
The battery lasts at least 12 hrs of intense usage.
Normally I have to recharge every second day (e.g. I charged last night, I answered a few calls, I did some IM and browsing and I still have 73% left).
For a phone with a 1 GHz processor, a 4.3" screen and a tiny 1250 mAh battery I find the drainage is rather decent.
Mind you, I ALWAYS do at least one full charging cycle to my battery after flashing a new ROM. I mean: full discharge, battery out 1 min, full charging in OFF mode, battery out 2 mins.

I have seen this process recommended a couple of times now. What is the theory behind it if you don't mind me asking?
maybe its also becouse some of us couldnt wait using the hd2 when they got it (like me) before it was fully charged for the first time
anyway my battery life has improved a little bit, i was at 74% this morning and did a lot of browsing, installing, tweaking and now its at 3%. it used to be much worse
I have battery consuming problem from time to time.I did everything:
installed new stock rom 1.66;
transfered all data which phone is using from card to phone memory(pictures,icons,sounds.etc...)
all updates are done manually;
Gprs connection is swiched off on the idle after one min;
One night it is loosing from 2 to 4%;
another from 30 to 40%
and it is eating memory from 10 to 15mb
I think that it is radio which is causing battery drainage so fast(to much communication wit a base stations,because when I am checking spb wireless monitor in the morning,there is no any data traffic.
I hope they can solve problem,because it is getting me mad and crazy
Try setting the screen brightness to 10-20% (on battery powered)
and dim backlight after 10 seconds (on batter powered).
It helps a lot, at least for me.

as far as i know, the battery has an integrated digital circuit (ic) which estimates the state-of-charge (soc). the procedure resets/calibrates the ic to obtain a more accurate estimation. since the radio rom is in charge with the power management (among other things), by changing it you decalibrate the "gauge".
i don't know if i've got the theory right but i tested this myself and it surely works.
Hi guys, this is not another rant post about battery life, but i'm starting to become really
frustrating with it, i tried almost all the solutions provided here on the forum but i can't
simply get the **** out of it. This is my story:
I bought the phone as used around 1 month ago (the guy who sold me the phone used it for around 1
month as well). I was quite satisfied about the device, but i noticed almost immediately the damn
poor battery life. With stock battery, my stats are (this is an average of the last 3 times i
used it):
Average duration: 27 hours
Average display usage: 2.5 hours
Average display %: around 45%
Average standby: Cell 30%, phone 15-16, other apps and android core 1-2
This with the following configuration:
3g off
gps off
background data off
bluetooth off
display brightness set to the minimum
no background applications or live wallpapers
No animations
No vibration feedback
No sounds
No widgets
Removed 5 touchwiz panels out of 7
Wi fi on (actually i noticed some small improvements by leaving it off)
The strange thing is, i noticed that the phone drains a LOT of battery while in standby. During
the night (7-8 hrs standby) my phone can drains up to 20% of the battery life. I read on the
forum that a lot of you guys have a battery drain overnight of around 2-3% which is 10 times
lower than mine.
So i thought about 2 possible causes:
1) Software related(processes or applications running in background)
2) Hardware related (battery ****ed up by the previous owner; phone not going in standby correctly)
Regarding the problem 1) i tried almost every solution provided here on the forum. Updated to new roms (JM5 and JM8) installed ultraslim roms, installed battery saving applications and task killers, performed some exotic "fixes" (removed battery stats file, tried to completely drain the battery following some procedures explained here on the forum). Nothing helped. To check case 2) i bought a cameronsino extended battery. Well with this battery i have exactly twice the duration of the stock battery. Last night i charged it to full before going to bed. This morning, when i woke up, the phone drained 10% (!) of the battery in 8 hours. So the stock battery is not the problem. What should i think then? that My phone is ****ed up? is There no chance to obtain a decent battery life? How is possible that a lot of guys have almost twice my battery life with stock battery?
I guess your phone may not be going into the sleep mode correctly ... try using system panel (from the market) and figure out which rogue app is causing the problem. Mine usually drains 4-5% at night.. (jm8 stock + voodoo)...
Ye, my battery just went from 48% to 3% in about 3 minutes. Does anyone have any idea why this is?
Same problem here. From about 43 % down to 7 % while it started to charge the battery with the original charger. Afterwards the Tab didn´t charge at all. Battery drained and got very warm.
I Called Vodafone and was told i have to send the Tab in for fixing. I hate waiting for the tablet 3 weeks.
Update: After 2 hrs. of waiting the Tab cooled down and i was able to start it again. Did a factory reset and was able to charge again with the wall mount charger.
Just wanted to bump this as my battery life is miserable and it discharges really fast in standby...
My HTC desire has been on for 52 hours, used for a lot of stuff and is at 20% battery.
The Tab charges to 100%, I unplug it at night and in the morning it has lost approx 10%, I leave it a few more hours and it't down to around 60%. This is with no use and no apps running!
I've tried killing apps or leaving them in memory and it doesn't seem to make much difference. I also use setcpu and have a profile where the CPU speed decreases when in standby to conserve battery?!
If I charge to 100% and use it constantly, I get fair life out of it maybe 4-6 hours of light use - some streaming over wifi, web surfing, kindle, sudoku etc. If I use it occasionally or heavily though, it dies very quick and if I leave it at about 40% on the evening, it's generally dead in the morning.
Why does it discharge so fast in standby??
Check to see if it continually searching for a signal. I've noticed that mine loses a lot of power constantly searching for a signal, cellular and wifi. So, I used airplane mode to conserve power. Remember that it syncs to different services that require it to periodically download data. That may be your issue.

Thanks Chuck, I use it in airplane mode all the time and only use web over wifi (bought unconnected in the UK). Would it still be syncing for email etc? I didn't think it could turn on wifi and sync itself but only when I turn wifi on. I always turn wifi off when not in use. I had problems with widgetlocker asking for superuser permission quite often and that killed the battery quicker so I removed that until it's fixed and saw an improvement.
I'm not seeing the times that other people are though, losing at least 10% overnight and there's nothing really running.
I installed battery doctor and the times it quotes are high for different types of usage and nowhere near what I'm getting.
I'll make sure email and calendar are set to manual update, adjust brightness etc and see what happens. It seemed better when I first got it so perhaps an app is draining it? I installed system panel to monitor this but it's hard to see what is actually draining it, any recommendations anyone???
Quite disappointed at the moment, ipads barely drop 1% overnight and I'd rather not have to turn it off to conserve battery when it should maintain it in standby...
Check the task manager and see what application are running. Also you can go in settings- about device - battery use to see if a specific application is using your battery out of normal. Also , the display is generally the battery hog, you may have set it to a super high level. One last thing you may have the buggy 3d gallery app, and it will show in the battery usage.
P_
this is an interesting problem. its very similar to the Apple Macbook Air.
The Macbook Air was very thin - very nice looking - however it needed to depend on wifi to do most things.
the association i am trying to build here is this: the Tab needs a bluethooth headset so you dont get all your calls broad-casted over speakers and that could drain the battery a lot.
for me the battery drainage didnt seem so bad and its been on for the last 36 or so hours. the battery icon didnt look like it moved so much and i was impressed considering this thing had a gigantic battery. then i loaded up a utility that read the battery and said i had 59% so my jaw dropped. not only is the battery indicator wrong there maybe rogue processes casuing the battery drainage. and this is on 2.2 which is supposed to be somewhat battery efficient.
i dont know - frustration is what i am all about here with this thing. it seems that every time i buy a new android device i want to move to another android device. no one is getting the damn thing correctly setup.
Am at work right Now, Charged the tab overnight, just few minutes ago my battery said 60% left and now the tab is completely dead, wont turn on, I ll wait until i get home to charge, fingers crossed.
Change the battery...

I am experiencing the same thing. Tab on flight mode and charged to 100% overnight. Unplugged at 9am, still on flight mode with no apps running, and it is 88% at 2pm.
12% drop in 5 hours with no usage whatsoever is way too much imo, comparing let say to my HD2, even not in flight mode. Wonder if they have a bad batch of battery for certain tabs........
Just wanna report back after my last post. When the percentage was dropped to 85%, I did a reboot. And guess what, now it displays 95% !!!!!!
5% drop from the morning til now in flight mode seems right and okay. Does it mean the tab is miscalculating the percent left?
PS.
I have been following the voltage in Spare parts this morning. All settings are the same (no apps opened, same screen brightness and in flight mode. Only turn on to record voltage)
94% - 4087mV
91% - 4081mV
88% - 4075mV
85% - 4067mV
But then after the reboot
95% - 4040mV
Man, I am not sure whats going on here........

let me jump in here again and share a similar deli-ma i had with my X10i.
while i was messing around with some custom roms i decided to stick to one that looked somewhat nice. well the funny thing is the battery indicator would always display 100% and for about 4 hours it would drop ever so slightly. then i removed the battery and put it back in -- the battery indicator showed 0% and i got a red light flashing ....
after screwing around with it for a bit i re-flashed the stock firmware from Sony-Ericsson and magically my battery meter and my battery worked fine.
so to sum up -- it maybe a software issue like the one i had on my SE X10i above?
As the title says, standby battery is awful.
I have all the bloatware disabled, only things on push are gmail and facebook messenger.
Cell standby is also sitting at 20% battery usage, no matter what, 2nd on the list behind screen time. Note 3 had exactly the same issue where cell standby is concerned. None of my other phones have had this issue, including my S2 with buggy as hell CM11, OnePlus One, Moto G LTE, etc.
No matter what I do, even with everything disabled and on airplane mode, there's a constant 1% battery drain every hour.
In my Note 3's case, this only happened on stock samsung firmware. When I flashed CM11, the issue went away completely. Something like 0.3% drained per hour instead.
So to me the issue is with Samsung's crappy software. I know the battery life was woeful on the Note 4 anyway before an update came in to fix things up a bit. Maybe they're saving the fixes for 5.0?
I know a new update for the N910C was released a couple of days ago too, but not available on European models yet.
Anyone else having these issues?
I dont have this issue at all my friend if i were u id try a complete wipe 1st, some people have had this issue too so returning could be an answer
Same here...
I only lost 4% battery overnight and don't have this problem too
20% battery loss on standby but mobile data was enabled.
^ you may have a bad app and/or bad signal
I have 4 bars lte at home, 2-3 bars at work, wifi always full signal at both work and home, one is ac 5ghz, other n 2.4ghz, no difference in drain either way.
Ive done a factory wipe 3 times now, even through recovery once. No change. Better battery stats and gsam both report no rogue apps, and ive also tested by having no apps installed, with and without bloatware disabled.
Im not really keen on the idea of voiding my warranty to test other kernels etc, and the only other option is to flash the ank5 update to test.
Ive attached another screenshot showijg the issue better. The drain gets noticeably worse after the first 50% or so, but that could be caused by many things, like inaccurate readings.
Like i say though, 1 of my 2 note 3s had the same issue. Could well be a faulty wifi/cellular chip.
Ignore the time its been on, the same thing happens during a day of heavy usage when in standby, same level of drain constantly.
1%+ may not seem that much to a lot of people, but with my usage i should get through 2 days regardless. It should be less than half of what it is. From the curent reporting in the battery stats, im losing almost 50% of my battery in standby over a day and a half or so.

Is location / sync off? Those a major battery drain during standby.

The only things enabled for sync right now are the basic google apps such as chrome, calendar etc. They rarely sync though, and no other phone I've used in the last 2 years has had an issue with them.
Samsung sync constantly returns errors so I leave that off.
Last thing I'll be trying tonight is a full wipe without disabling any built in apps. Its doubtful, but maybe one of the core shamsung apps are trying to communicate with a disabled app or something. I really don't know.

Any update?
My n910c is terrible too. 15% battery loss in 3 hours of standby alone! Wtf! Tried every battery saving trick' no location on etc...
i would suggest u do few thing while u get on bed next time,
Full charge your phone and unplug before you on bed,
1. Restart the phone while on charging,after restart go to home screen and lock the screen and unplug then go to sleep,check it at the next morning u wake.
2.Left the phone with your daily apps running,full charge and unplug then go to sleep,check it at the next morning too when u wake.
this is how i solve those apps running not right.
like the screenshot below,
An apps running at night drained 30% battery within 6hours & 30mins & without switch on the screen or touch anything since i'm asleep *with wifi on*
2nd screen shot shown that cm browser running and consume 94% of processing among 30% battery
while cpu only running 20mins since i had weather & sync on during night.
After that i report to cm team and they send me latest version,
after re-install my phone just back to normal.
now my N910c note 4 is consuming 1% every 1.5hours standby with wifi/3g connected *my area 4g only 1~2 bar so i changed to 3G*
average daily usage were 4.5~5.5 hours screen on time with social apps,browsing infomation,checking e-mail every 1or2 hours,reading news with flipboard,news app,drawing something,watch some youtube video & with auto brightness but indoor most of the time.
hope this would help you

I did a full wipe, installed ANK5 update, unplugged at 10pm at 100%, woke up at 7am with 97%. This is what it should ALWAYS be.
However, after the 2nd charge after the full wipe, it's back to what it was, if not worse. Last night I unplugged at 11pm, woke up at 7am with 92% left. That's bang on 1% an hour again.
There is nothing keeping the device awake at all. It's very frustrating.
I can only assume Cell Standby is so high due to the fact that the phone isn't actually doing anything while the screen is off. After a 20hr day with only 1 hour SoT it's sitting at 72% battery left, with cell standby at 31%, just above Device Idle at 29%. It's a mystery to say the least.

average daily usage were 4.5~5.5 hours screen on time with social apps,browsing infomation,checking e-mail every 1or2 hours,reading news with flipboard,news app,drawing something,watch some youtube video & with auto brightness but indoor most of the time.
hope this would help you

Thanks for your post. I'll definitely try restarting etc again beforehand. I'm also considering another wipe, as S-Voice being disabled seems to cause quite a few errors in the camera app. The battery drain increased after I opened the camera app too, even after force closing etc. That could just be coincidence though.
1% every 1.5 hours still seems like a lot to me, but it seems like you have a lot more apps and things running, so it's actually very good!
Very tempted to just root the thing now and throw on a debloated OS and custom kernel.
Last night i go sleep with 10% of battery left, ( im not force closing any application at all - just exit ) when i wake up ( about 7 hours of sleeping ) phone was showing 8%
No data/wifi/gps etc. If you are not using mobile internet, switch to GSM! It takes more than 30% less battery power than 3G
I'm thinking this is a hardware fault of some sort. Maybe battery, I'm gonna replace and see cause tried from full charge placing it in airplane mode to see if signal was causing the problem, didn't touch it, screen off whole time for 2 hours. Upon looking at it I saw I'd lost 7% battery! Omg! In airplane mode?! In 2 hours?! In standby?!!
In normal use there are no Rouge apps or strange readings in battery stats at all. May be hardware fault.
I've had the N910K exynos, 6 hours plus sot battery life
I've had the N910F snapdragon, 6 hours plus sot battery life
This n910c give me 3 hours sot. I'm pissed lol. Right off!!
Thats really weird, it can be issue of the battery. My 910C has about 8/9 hours of SOT ( wifi only ).

I have 4 bars lte at home, 2-3 bars at work, wifi always full signal at both work and home, one is ac 5ghz, other n 2.4ghz, no difference in drain either way.
Ive done a factory wipe 3 times now, even through recovery once. No change. Better battery stats and gsam both report no rogue apps, and ive also tested by having no apps installed, with and without bloatware disabled.
Im not really keen on the idea of voiding my warranty to test other kernels etc, and the only other option is to flash the ank5 update to test.
Ive attached another screenshot showijg the issue better. The drain gets noticeably worse after the first 50% or so, but that could be caused by many things, like inaccurate readings.
Like i say though, 1 of my 2 note 3s had the same issue. Could well be a faulty wifi/cellular chip.

Your mobile signal is very poor. I believe you have full bars but your screenshot ... well it shows us that your reception is poor. It may be one of the causes for your fast drain...

Yes, in airplane mode I should lose practically nothing withing 2 hours. Please screen shot your battery stats for us!

My SoT is fine if im only using it during 1 day. Its usually close to 6 hours. But its not heavy usage, just browsing mainly.
Let me know how the battery change goes. Im likely going to order a spare anyway for when im away from home, so will also report back.

So mobile data completely disabled? Not that it should matter much if youre on wifi all the time.

At work its pretty poor, usually a bar or two on lte, but no other phone ive had has displayed battery drain like this in standby.
That still doesnt explain why it drains 1%/hr with nothing happening at home though with 4 bar lte and full wifi signal.
Ive also noticed voice calls are taking up significant battery. A 3min call used more battery than 20 mons of screen time at half brightness apparently, unless thats normal.
If its normal, then to me the cause seems to be battery related. If not, then faulty cellular chip.
Also heres some more screenshots.
This is over the course of the day with barely any usage.
The chunks where its awake, that's just when I'm playing music, not a rogue app.
Note the big standby drop at the start, then the standby drop later, both completely different amounts of drainage, yet both when doing nothing.
Hello,
So I've had the V20 since it first came out and I'm loving it. With the stock battery, I'd charge it every night and not notice many issues. Noticed a respectable 3-4 hours of SOT, which is decent but not spectacular. Then i got the Zerolemon 10,000mAh extended battery for it and I still feel like the phone doesn't have the battery life it should. With the extended battery in, I would sometimes leave it unplugged overnight and lose 15-18% (which, in a 3x battery, correlates to almost 50% of a stock battery) in just one night. So i'm wondering, any apps/servies that just guzzle battery overnight? Any info is a help, thanks!
Good possibility that the new battery you have may be junk.
But you'll have to pop the stock battery in and do battery usage comparisons between the two.
Have you calibrated the Zero Lemon battery? Run it all the way down until it turns off the phone. Pull the battery and then put it back in turn the phone back on to make sure the battery is drained all the way.
Then recharge it without disturbing it. Recommend doing this overnight.
Also make sure you aren't switching batteries once you've got the lemon calibrated otherwise your battery gauge won't read accurately.

Yeah i might have to, i've been trying to avoid that. I honestly think that it's the phone not the battery, because when i leave it alone overnight it loses like 12-16%. Losing that even off a stock battery is ridiculous so i figured it was something with the phone that caused it to run all night without dozing. i read up on some threads about wakelocks after installing GSam and seeing that the phone is held awake quite a lot (as i type this, i'm sitting on 72%, 13h16m of usage, 3h5m SOT, and 4h28m held awake. So i honestly think it's the phone, but then again if i do drain it down then do a battery pull and it jumps up to 30-40%, then i'll know it was the battery
Also, would you recommend once the phone shuts off plugging it in and leaving it off, or turning it back on once i plug it in?

Don't think its the battery, it's highly likely the ROM you're using. I had terrible life after the last update.

I'm running bone stock on everything, no root
Update: been getting significantly better battery life after doing two things:
1. Turned off Bluetooth location scanning (I already had WiFi scanning turned off).
2. Using my phone without WiFi on (on the chance that it might be the WiFi causing wakelocks, which is something I researched a bit with the help of GSam. Wifioffdelayifnotused was the suspected culprit).
I'm not sure which one could be the bigger factor, but I'm going to leave my phone unplugged overnight with WiFi off, then after tomorrow night when i charge it fully again I'm going to see how much battery life I get with WiFi on (this way I should be able to determine if it was the Bluetooth scanning, or the WiFi.)
Any input would be appreciated. Thanks!
Had a zerolemon on my Galaxy S4 and while it was a great battery that added a lot of additional life, I never felt I got enough extra life that corresponded to the amount of mAh that the zerolemon brought. Though it wasn't anything like what you are describing. Just never felt like I got 3x the battery life even though it was like 3x the mAh amount but maybe that's just because I don't understand the whole science behind the mAh ratings on batteries.
Update part 2: turning off the Bluetooth scanning and Wifi (only yesterday, had wifi on today) has resulted in much better battery life so far. Oddly enough, early on it seemed a lot better, on pace for almost 15 hours SOT. I'm at 18% now and almost at 10, but still pretty good and better than what I was getting. I'm chalking it up to the Bluetooth scanning since I use an Android wear watch that I leave always connected. I'll do another full drain tomorrow after charging it tonight, this time leaving wifi on to see how much of a difference the Bluetooth scanning makes (3rd pic is early on when I was on pace for 15h SOT; left phone unplugged last night and stayed at 64% all night. So my 12-18% overnight drain (40-ish% on stock battery) problem is cured )
hi
my v20 phone battery draining was about 1% per hour before (about 7% totally ) and recently increased to 2% during sleeping time overnight. (draining 15% overnight in sleeping state) .this situation's screenshot is attached and named : Screenshot_2018_01_21_07_05_15.
it seems that during day either performance off battery is decreased.(about 5h with wifi and screen on usage)
Fast charging while second screen is On , is slower than when it is off therefore when second screen is Off , fast charging goes better . exactly , first 30 mins fast charging makes about 40% battery charge(instead of 50%) and after 60 min leads to 85% and full charging taking place after about 100 min instead of 80 mins.
another important thing is that sometimes shades have been seen on the LCD that many users have complained about it.
phone information is :
Android security patch level: September 1, 2017
BASEBAND : MPSS.TH.2.0.1.c3-00045-M8996FAAAANAZM-1
KERNEL : 3.18.31
BUILD NUMBER : NRD90M
SOFTWARE VERSION : V10g-AME-XX
MODEL NUMBER : LG-H990ds
my actions are as follows :
phone is factory reseted. No third party apps is installed. [especially social media apps.]
battery calibration steps for not rooted phones is taken place.(turning off the phone and charging several times repeatedly).
testing battery drain in safe mode in done and didn't change results
turn off location services and location scanning for WiFi and Bluetooth scanning
turn off WiFi being On during screen is Off.
turn off auto sync, NFC, GPS etc.
not using auto brightness.
not using comfort view .
turn off location services and location scanning for WiFi and Bluetooth scanning
second screen is off during test overnight. (either with second screen is ON with faced down to lower brightness in other day test [this situation's screenshot is attached and named : Screenshot_2018_01_21_07_49_27] )
phone is in Air Plane Mode and all data services is off.
system apps like Google services and Play and Assistance is limited by permissions.
following are some advanced battery drain overnight figures of my phone for more analyzing.
any help with this issue is appreciated.
