Hi -
I've had my HTC HD2 a few days and although I'm happy with it's features, I'm really frustrated by the poor battery life. The first day I used it the battery was dead within under 12 hours from me starting to use it, and at the start it was fully charged. On this first day I did have email and weather etc on auto check though.
So last night I disabled weather, set email to manual checking and disabled a few other things, but did leave HSDPA and 3G on. There was a slight improvement today but not much, the battery lasted the full 12 hours, but with only 2% remaining.
Both days I don't think my usage was very high. I'd maybe had 10 minutes of phone calls, sent around 10 text messages, listened to 45 minutes of music, checked one or two websites, and played games on the phone for about 15 minutes. Imagine how it would be when I need to make several calls in a day.
I have searched the forum for tips on improving battery life but the main suggestions seem to say that I should disable HSDPA and 3G but one of the main functions of the phone is internet usage and I don't see why I should how to switch to manually putting these settings on and off each time I want to use the internet, just so I can get a longer battery life - the battery should be able to cope with moderate usage!
Does anyone have any further suggestions?
Thank you
Look for an application called 'Bandswitch', it can disconnect idle connections. THis way 3G won't be enabled when you don't need it, should save some battery.
Disable automatic screen brightness and set it to something like 30%.
Disable location services and stuff.
Give the battery some cycles to reach full potential.
But of course, gaming, internetting and listening to music will drain the battery faster. It lasts about 2 days for me with moderate use (some internet, some playing around, etc) which is pretty fair imo.

I'll give that a try. So will it automatically enable it when I start browsing the internet or something?
I already changed the screen brightness and disabled location services though. That didn't seem to make a big difference.
And how much difference does giving the battery some cycles make?
Thanks.

Sorry, but it doesn't work that way
Bandswitch can definitely do 2 things- it can disconnect idle connections, which will reconnect when needed, but this won't switch the transport between 3G and GSM, and has little effect on battery life
Or it can be used to manually change between 3G and GSM, using whichever is selected for its current transport and then autodisconnecting if required. It is the action of switching to GSM which has the most impact on battery life, but there is no way to switch automatically between to 2 as it needs a phone radio off/on to execute the switch.
Poor 3G signal conditions will hammer the battery because the phone will continually hunt for the strongest signal and switch constantly between modes. If your 3G signal is less than 2 bars I'd suggest switching it to GSM until you are in a stronger signal area. Do this by going to Phone/Menu/ then scroll down to Band and from there switch between Auto and GSM. If that makes a difference then you could install a small utility to make the switch easier to access.
seems very odd, mine was fully charged around 11pm last night, have sent around 20 texts, 20 mins calls, had wifi on, done some browsing, abit of sat nav and its on 68% 20 hours later.
I get at least 24 hours with moderate use. Most of the time i get around 30 hours.
I have weather and peep updating automatically + email retrieval at every hour.
When I first got mine it was lasting less than 12 hours too.
Now I'm on ROM 1.61 and have the following settings:
HSDPA disabled
Weather update every 3 hours
Twitter updates ever 1 hours (though it actually only updates when I scroll to the Peep tab)
Facebook auto updates - Off
Stock auto updates - off
Bluetooth and Wifi off unless needed.
Screen brightness - 30%
Haptic feeback, Vibration - off
Push Email - On
I'm getting over 24 hours of life out of a full charge now. I have got the push email set to manual updates only during off-peak hours ie when I'm sleeping. During the night the charge drops around 1% per hour. It was at 47% when I went to sleep last night and was 40% when I woke 7 hours later. This seems to be typical overnight drop for me.
Over my first few days of tinkering and setting up I found the battery drain to be massive. Once you settle down to regular usage it is a lot lot better.
However, just to be careful, I do now have a desk cradle at work so I can charge my phone if I have to.
Prior to my most recent hard-reset I found that if I left the phone in stand-by over night, with it checking for email every 5 minutes, and weather every 15 minutes, the battery would go from 100% to zero in less than nine hours. And that's without using it at all! As an experiment I tried turning off everything that could possibly be using the data connection, and turning off 3G, so nothing was running at all except the phone in 2G mode listening for calls and texts. It still burned 20% of the battery overnight in stand-by.
Since doing a hard reset, if I repeat the second experiment then I find that overnight battery drain is now only 4% - so clearly some piece of software that I had installed prior to the reset was hammering the battery even in stand-by. Quite what it was, I'm not sure yet. (My current prime suspects are the task manager and 1% battery status icons).
If you're having battery drain issues then I suggest doing a hard-reset and then not installing anything remotely controversial for a day or two to see if that sorts out the drain. If it does, then you can start reinstalling things gradually to see what difference each one makes.

Oh, I misunderstood it then... thank you for clearing that up!
It's very interesting, to see the number of people who have battery draining problems. I have the french SFR ROM 1.44 and since the beginning found my battery life satisfying (I didn't expect long life, as my wife has to charge her iPhone every night).
My battery lasts in heavy use 24h (though it can go down to 18h when using internet by 3G/HSPDA for long period like 1h or more) and under "normal" daily use (checking e-mail regularly, 20 min phone calls, sending some SMS, 30 mins internet, 45 mins playing around / listening some music) around 1.5 days.
My settings are:
3G/HSDPA enabled
Weather update every 6 hours
Stock auto updates - every 8 hours
Bluetooth and Wifi off unless needed
Screen brightness - auto
Haptic feeback, Vibration - off
E-mail check: every 2 hours (POP3)
Faulty batteries? I think not....
Whilst I'm a master of google searching, I get worse results using the search facility on this forum than just using intuition.
Anyway, I just wanted to add my comments on battery life after owning a stock 1.43 phone from Vodafone UK. I was getting less than 8 hours life with everything on auto and making just a couple of shortish phone calls and a couple of quick browses. The rest of the time I was in standby and I thought that my phone was one of the worst out there. I had also installed Skype which I had running in the background which sometimes causes the phone not to go into auto-standby even though it would dim normally. I also noticed that I was in a very weak signal area and that my phone was constantly switching between 2G/3G/H which I understand can consume a lot of power. Also, I had stopped using wi-fi to see if that helped.
After reading a million threads, I decided to conduct an experiment last night. Usually if I charge the phone before going to sleep for 8 hours it is down to 70% when I wake up having been left in standby. So last night I disabled everything. Turned off 3G, data connections, My Location, Weather update, Stocks Update, FaceBook login, e-mail updates, Skype, bluetooth, wifi. In fact absolutely everything I could find that could be turned off except the basic 2G phone itself.
Guess what, I wake up 8 hours later... 96%.
16 hours later.... 81% with very light use.
Now I'm going to have to spend many days playing around with different settings to see which apps or functions are gobbling the power. I have a nasty feeling that the weak signal is half the problem
So cheer up! It's not ideal, but this is a brand new, smartfone with bugs - not a Nokia 6110. Higher capacity batteries and ROM updates will come. In the meantime you just have to figure out what is sucking up the juice on your HD2 and disable these functions if you don't need them or when you are not using them.
Good luck and enjoy it! The coolest phone around...

Hello everyone,
like the majority of the owners of HD2, in order to optimise the duration of accumulator charge, I use Band connection control programs , to pass in 3G only when it is necessary. Thus, I have:
- phoneAlarm: to force the 2G mode the night, and also for differ quiet mode if I am in meeting, etc…. In particular, in the case which interests me there, I force the 2G the night and asks to pass to 2G the morning.
- WMlonglife (version for HD2): which normally loads himself to make the effective switch 2G towards 3G or 3G+ if an application program requiring it is launched, and otherwise to remain in 2G. It should be noted that WMlonglife has two applis, one for the configuration, and to make manually changes 2G 3G, WMbandswitch.
- recently, I tested Bandswitch v2.8
I meet the following phenomena, and I would like to know if others also have them, and/or if there are parameters to change so that it goes better.
Point A: Already some question about the icons of the bar of state in top.
There are always two icons side by side. Tell me if I interpret them well.
one with a letter: G= GSM, E= Edge, 3G = 3G, H = 3G+
This letter tellsonly that this kind of network is available, but it does not say that one is actually connected there. Is it well that?
To know in which mode one is actually connected, it is another icon, on its line, with the 1 to 4 bars of reception and a small letter, which should be looked at.
This small letter, it is “H " ==> connected in 3G+, “3G” ==> connected in 3G, “E” ==> connected in Edge
and finally a simple antenna, which I imagine wants to say that one is just connected in 2G, no data connection
Is what all that is correct?
Is there another mean of knowing in real-time the current mode of connexion (and thus mode of conso of the accumulator)?
Point B, use of Phonealarm:
like said in introduction, I force the 2G (mode GSM/GPRS) during the night, and to 6:00 of the morning, I pass it in mode “house” where I put “Car”, by also putting the pin number at it, because it seems that for this transition, one needs the pin number (is it the radio cycle on-off?)
There, the first thing, they is that every morning, when I unlock it I find myself with the screen for input of the pin number, where it is enough to make cancel (because the code already entered via PA and even already connected). Moreover, if one tries to enter a pin number, then he refuses the input.
on the other hand, at this time, the telephone seems to remain in Edge icon “E”, and does not pass in H. On the other hand, so there I reset, then he will connect to H with the boot
Have you also this history of pin number?
For hangs, it is as if WMlonglife did not take the hand to force a 3G mode or 3G+….
this brings me to the point C
Point C: WMbandswitch… after a software reset, my Tel. is connected automatically towards the 3G network (or 3G+) of orange. On the other hand the morning (after to automatic wake up through PA), it remains in E. When I test action manually a passage in 3G with WMbandswitch, it does not change anything. I tested with radio operator chip on Samsung, or Qualcomm (WCDMA). similar behavior….
To check out, I then loaded and installed Bandswitch 2.8, and tried to change into 3G, and there I see appearing the letter H. so, there is a difference with WMlonglife, which would seem to show that WMlonglife does not manage to make the switch towards 3G.
Which radio chip put in WMlonglife?
Have you to it even thing?
Poind D: use of bandswitch 2.8 (on xda): I tested. Hard to know if that is interfaced well with all the remainder. Of your experiment, which one would you advise? It does not have the system of “whitelist” like WMlonglife…
Here is, in synthesis, to summarise my questions
- Has: major significance of the icons
- B: phonealarm and switch of the 3G mode (after a forcing in 2G the night)
- C: WMbandswitch, and configuration/use for HD2
- D: alternative to WMlonglife?
For info, with normal use of browsing, email and phone, I drop of about 50% battery for 24h, that is not so bad, but I 'd like to make sure about the Bandswitch thing...
Thank you in advance for all…

How is the battery in your Optimus 7?
I don't have an exact estimate but I guess around 10 to 12 hours of normal use. With heavy usage like using Gmaps drive mode on and playing games I get a lot less battery time, though I still haven't made a true test.
My previous cell phone, Samsung SGH-T459 lasted me for days, it was truly a marvel but it wans't as pretty to look at as my LG E900. Though it had many more basic functions than my LG E900
Yeah sadly powerful phone != good battery life. Looks like you get basically the same as me. I bought 2 batteries and an external charger from Hong Kong for $15 though, so that should help.
My battery lasts for about a day and a half of normal use with UMTS and wifi on 100% of the time, with the odd game thrown in. I also have a Galaxy S2. The same use sees about 9 hours of battery life on it. I find the battery life of the E900 (with Mango beta) extraordinary for a smartphone and I'm very honestly thinking of selling my SGS2.
I see three types of scenario
normal day: no wifi, 6 hours of normal usage, plus 18 hours of laying in one place, and then it says "battery critical"
out of office day: 8 hours of moving in areas where are no GSM network in range (basements, garages, etc)
weekends: no wifi, laying in one place almost 2 days
My LG E-900 survives 2 business using the following settings:
- Regular 7392 software
- Connected to Deutsche Telekom (900 MHz)
- EDGE instead of UMTS
- No wifi
- No GPS
- Turning off data between 22:00 and 7:00 manually (i hate email notifications at night)
- E-Mail push for Active Sync account and 15 min pull for IMAP
- Daily Facebook sync
- Frequent reading of emails and writing about 5 mails per day on the phone as well
- About 30-45 min. phone calls per day (i have a fixed line in my office so it's not much)
Compared to my Samsung Galaxy S this is quit good, under the same conditions the Samsung asked for the charger during the 2nd day, the LG E900 has still about 25%-30% capacity at the end of day 2 (22:00).
As I use the LG E900 more and more my "old" HTC Legend is breaking standby records every week, about 7 days without charging. I don't use data or voice with it frequently, but it is connected to the UMTS network (O2 Germany offers GPRS and UMTS but EDGE only in very few areas). On my last cruise vacation the HTC Legend survived in standby connected to the GSM cell on the ship almost 10 days. Thus new cell phones still provide a good battery life in case you use them as regular phones, but who wants to do that?
5 days is my record
1 or 2 short calls/day, a few texts/day.
Location services off except when (rarely) needed.
Wifi off except when (rarely) needed.
Email sync on demand only (3-4 times/day).
Check trains/tubes twice/day.
Don't use it at all for music/radio.
This results in 3-5 days life.
I'm getting about 1.5 to 2 days normally - a mixture of texting, tweeting and internet, as well as the occasional call, switching between WiFi and 3G throughout the day. Obviously hitting up the GPS or internet radio kills it (about 4 hours of Tune In Radio take it to flat from a full charge), but I'd have to say I'm pretty happy with it, even after being used to a Nokia.
hi...i just bought an e900 and my battery life is terrible with latest rom.
like 6 hours and the battery was 40%. didnt do much on it!
The same problem. I'll try to reflash to Open Europe. Originally I have StarHub
my battery with:
3g active
gps active
data active and push in real time with facebook and gmail
i start my day at 8:30 and finish at 00:00 and beyond one o'clock my optimus tell me to charge.
mango update rtm
i live in italy and my operator is telecom italia mobile
I have no signal at home (from 19:00 to 00:00 and beyond)and when to look for signal consumes more energy from what we know
sorry for my bad english
Nothing Changed for now.
At 9am I disconnected phone.
At 7pm battery was critically low

Short battery time
I am having the same short battery issues you are describing and also the battery status indicator bug...
I made an experiment the other day. Fully discharged my phone and then recharged it to 100% at night. Turned data on (HSDPA 1900), wifi and location services were off, and activated battery saver mode. No app was open.
In the morning (7 hours after that) as soon as I woke up I checked the battery meter. It had 68% left!!! How could the phone lose 32% of its charge without doing anything but staying idle?
This is a way I found to charge and use your phone when your phone goes off due to low battery. This has been tested on the LG Optimus 7, HTC 7 Trophy, Samsung Focus and HTC HD7 so this may work on other devices. (Unknown about the Samsung Taylor or LG Panther)
1. Make sure your phone is off due to low battery and can still switch on
2. Turn on your device on.
3. Wait 5 seconds after you see your OEM logo (e.g. SAMSUNG, LG, HTC), then plug in your charger. (If your device turns off before 5 seconds or cannot switch on at all, this will not work for you.)
4. You would see your OEM logo for a few seconds and your network provider logo (depends whether your device is OPEN or using a Carrier ROM) then you would see the animated Windows Phone logo and your SIM PIN or Wallpaper.
Troubleshooting:
If you feel a slight vibration or hear the "low battery" alert and the device goes off after the animated Windows Phone logo, you have either waited too long, charger is faulty or not turned on or your Windows Phone does not support this.
If your device turns off before 5 seconds or cannot switch on at all, this will not work for you because your battery is completely dead. Charge it properly for 8 hours.
Thanks,

(NOTE: This works only for versions 7.0.7004, 7.0.7008, 7.0.7355, 7.0.7390 (NoDo), 7.0.7392, 7.0.7661 mojo, 7.0.7712 mojo, 7.0.7713, 7.0.7714 and 7.10.7720.68 (Mango) flawlessly. It does NOT work on 7003. DO NOT do this on 7003 as there seems to be a bug in the device firmware which MAY render the device unusable. 7003 users use this AT YOUR OWN RISK.

Have you unbranded your phone? Did you force the Mango update? If you did so, you might be missing the LG firmware update that's supposed to give longer battery life.
I had the same short battery life issue, and it went away after I rebranded my phone and got the 1.0.9.10 firmware for my e900h.
If I use only for calls, sms and mail (with wifi on all the time) probably 2 days, but if I play games,music, videos etc. only half day. If only there was a better battery available.

I haven't unbranded my phone, as it still displays Vodafone as the carrier and I got all the updates keeping it branded. I forced the mango update because my country only got marketplace support after that update (I live in Colombia) and I wanted to have a fully functioning phone and not have to wait a month or more for that. I did get a couple of LG updates, one after NoDo (If I remember well) and the tethering update too.
You suggest that those that forced the mango updated missed an LG update, are you sure about it, or just giving your thoughts? For what I've read I haven't found a pattern yet, as I'm not the only one with the feeling that battery is not lasting enough. Also, i think the 1.0.9.10 FW is for E900h only, I have only seen that FW in the posts related with phones from Canada.

I'm sure of it for the e900h and I see no reason as to why this wouldn't apply to the e900.
I had abysmal battery life after forcing the Mango update, my phone could barely last a day.
Now, that I received the missing LG update that a forced Mango update skips, my battery life is much improved. While 1.0.9.10 is e900h specific, I am sure that you can check to see what firmware version others with the e900 have to see if you are missing a driver update.

Same here.
Battery life on my LG Optimus 7....
Mine's like only 10-22 hours... But it should be more like 50h+ atleast when it's in standby mode but it isnt.
The question will be if it is worth to buy a new battery to check if it can last longer?
No Bluetooth, No Location - Yes WiFi, LTE 100% signal coverage, no downtime, overall low brightness around 25-40% I can't seem to get past a day of regular use with 2 hours and half average screen time. Using latest OTA.
I've turned off the always-on screen, several bloatware that came preinstalled, including Facebook and Whatsapp.
The first on the battery usage is always Android System followed by Cell Standby then Android OS (again???) and then Screen. Also the voice call seems to use some great amount of battery. Naming might be different since my Android is in another language.
Have turned on energy saving for most apps that runs on background. Doesn't help much since I don't have many apps that runs on background. Imagine if I did! My day ends with about 20~27% battery left, I just turned off fast charging to see if it helps anything. My Xperia Z3 with Whatsapp and a great deal of apps installed would end the day with over 50~65% with Stamina Mode. I know the screen is smaller but so is the battery.
So I thought it would get better with time but it didn't, it's the S7 Edge Exynos Single SIM, unbranded with the official Samsung rom so I could get the latest updates or I would be stuck with no updates at all since Frebuary, since my carrier usually only releases major OTAs such Android N and skips all the minor updates.
Yes I did a factory reset already hoping for the better, maybe I got a defective Galaxy S7? I'd hate to have my phone fixed and the battery changed, it wont be the same again unless they give me a new one which is unlikely.
Why is Android System and Android OS draining so much battery? Are there any tools to debug this and trace which processes are using CPU time? Or could this be due a faulty battery?
Settings, Applications, Google. Disable all the services that will cause wakelocks such as all security options. This is something 99% of folks overlook or forget. Post a screenshot of your battery stats

Here is an average day with:
**Few moments connected to my laptop transferring pictures from yesterday - so incidentally it took some charge on the way.
1 hour 29 minutes voice call, 3G/LTE signal is excelent, VoLTE not used, WiFi on occasionaly, Location off, Bluetooth off.
1 hour 12 minutes running Fallout Shelter with power saving on, 30 fps low resolution mode, that's the CPU time at least.
2hour 28 minutes screen time with very dim brightness
Power saving ON all apps where available, I have absolutely nothing installed but a couple of games, Teamviewer and Microsoft Remote Desktop.
That left me with 49% battery. Not sure how great the results are considering the brightness was very low.

Dont quote me on this but I believe the Android System drain issue is a byproduct of the latest Samsung firmware update...

Just some heads up, in offline mode my phone went a full day with a 6% drop, half hour screen time and some minor gaming, when I turned the phone radio back on around 20:00 when it was 10:00AM it was down to 15% battery, solely on standby. No bluetooth No location - Yes Wireless Yes LTE
Experts, if thread is wrong placed or duplicated, please remove it.
I have the following situation. Bought in US LG G3 phone for a kid. Phone was stated 855 ( I live in Europe). Once I bricked him trying to revert from 5.0 to 4.4 due to huge bateery drain, it was found that actual MB model is 851 TMO.
The current situation is:
1. Phone bootloader unlocked, rooted, installed 7.1.1 Nougat, Lineage OS 14.1-20170108-UNOFFICIAL-d851 flashed with adb.
Modem is: MPSS/DI.2.0.1c1_13-00009-M89***
2. Recently purchased 4G SIM from virtual provider of Partner
3. Kid complaints on following:
- battery drains to 0 in 2 hours ( new brand battery, manufactured 8 months ago)
No applications installed - GApps pico, Chrome, Root Checker and Waze.
APN be default were set to Partner 3G portal.
I changed APN to fit virtual provider settings:
- slow surfing - I took the phone today and it indeed switches all the time between 3G and H. Talked to provider, looks like they sent me wrong SIM ( 3G flashed ).
I also see in battery usage - Mobile Strength signal - a lot of yellow lines inside green.
Network signal is HSDPA @ 7.2 Mbps
I made cross SIM test - took the SIM from a friend ( different provider and tested it with my phone) - H+ all time and Network signal is HSDPA @ 42.2 Mbps
My "blaming finger" is SIM, but Im not sure this is the main issue for battery drain.
So, I expected to get a new SIM from provider and will test it.
Q1: Am I suspicions or it can be SIM issue?
Q2: I need battery good life ROM. I'm new to LG ( mine is A0001), so I'm not sure either stay with original TMO ROM, go to AICP or else ( preferable Nougat, otherwise MM or Lollipop much better)? The most usage is surfing, WhatsApp, etc
Q3: How to set LTE correct settings? the "4636" code gives me only testing mode?
Any help will be appreciated.
Unstable signal drain your battery, just check the battery life without the sim.
I have the battery problem everytime i flash an AOSP; if i have full 100% battery and reboot the phone i got 4%-10% battery and the phone shoutdown cause no battery after a minute.
Btw try to calibrate the battery Apk

Thanks mate, planned to do so. I remember that it was like 1 day standby with 4-5% battery lost only when no SIM was in there. will try again overnight.
Basically you say - go with Stock ROM? I'm a little scare since i can potentially loose ability to surf at all.
Tried wife SIM in there and no stable stable as well, when this SIM works well at her OnePlus. Still the result was better. Possible I have to clean all APN and stuff ( cache, so so so) before letting new SIM in.
or those are both bad SIM + bad ROM...
Hi,
My Samsung S8 since last upgrade to Oreo was a complete disaster. Just to be clear battery life during Android Nougat was good and it was the first thing ive noticed that samsung completely stepped up their game since their battery disaster on their certain phone model. Battery life would run at least from a day to 2 before recharging. Ive noticed there are other threads similar to these so i knew im not the only one affected, my colleagues also experience similar issues since upgrading to oreo so this is not something isolated to my s8 phone.
Few key points that ive noticed since upgrading to oreo:
1. Going to settings then battery usage. Screen would be the foremost battery hog at 26%, followed by Android System at 13%, then Device Idle at 9-8%. Cell Standby and Android OS remains normal.
2. Go to Settings then App. Ive noticed by checking each one of the apps that beaming services, device maintenance, settings, gear vr services were among the ones that took up most of the battery usage this is excluding system apps like AASAservice, etc.
3. Go to settings then data usage. The Android OS is sending or receiving 100MB of data (still counting). I wanted to know what are these data that is worth 100MB.
4. Device easily gets hot even light use of facebook, ig or 7 minutes of youtube video.
5. It sometimes restart, this is rare but ive noticed it since fingerprint cannot be used initially when there's a restart.
Now what ive done so far:
1. Cleared partition cache by holding bixby btn, volume up and power.
2. Disabling unused apps, even certain bixby services, etc.
3. Went to developer option and disable always on mobile data.
4. Factory reset device hoping it would go back to nougat but it did not. With a mint condition reset, it still drain too much battery. (without any third part apps or data restore)
5. Called up samsung customer service but was told to go to service center. Went to service center they check the ASOC of battery (which i think is unrelated) and according to them reprogram oreo. which did not help. wasted my time.
Now what is the implication?
1. I need to charge my phone at LEAST twice a day.
2. It heats up the phone which would definitely have negative impact on the longevity of this device one way or another.
3. It drains too much battery, with the amount of charge discharge multiplied at least by 2, this will literally messed up the battery life in the long run.
4. Im currently using 2 phones and my samsung s5 which is a 4 year old phone had better battery life. lol. Since in just 3 hours it consume almost 40% of battery.
There are tons of related post like these on different forums and on reddit but i surmise i should dig more on this problem before writing a more concrete post. At this point, i can only see 2 remaining options: 1. There is a step online that would revert the OS back to nougat but this would involved third party apps like odin, there are risk involved like phone brick, etc. Im not sure if it will void the warranty. OR i can just wait for a patch from samsung.
Now SAMSUNG NEED TO FIX THIS ASAP or provide us a way to revert back to nougat. With the s9 just available at the market, this terrible oreo release could not come at better time. I know there are several issues like the battery issues with their previous note model and Apples intentionally slowing down their phone, Samsung got to fix this fast before this issue becomes a blowout and many people will start to notice.

On what version of Oreo are you? Since CRC7 batterylife is great.
Android 8.0.0

What security patch do you have and what can you see under "Baseband"? Everything will be fine with latest March security Patch and CRC7 Baseband. Just be patient, if you do not have it, yet.

I have the same issue but thanks for the info as I'm still on the February security patch
I have to agree CRC7 shows good improvement with battery life

Man, i´m totaly on same boat!
In CRC7, i'm experiencing terrible battery life. Max 2.00 to 2.30 Screen on time in one charge. Now, for the first time, i have to recharge my phone befoure dinner.
Wifi , Bluetooth, Aod On, location history Off.
It´s the worst experience on any phone that i had in the past.
Like you, already disabled some apps, clear cache and already done a fresh install. Nothing works, nothing improved my battery.
I´m thinking send it to warranty, but it´s probaly not worth the time...
Maybe it´s time to forget about Samsung phone and move on. P20, or even iPhone X...
After updating to OREO and updating all galaxy apps, "beaming service" was draining my battery (67% of the battery actually). After uninstalling the updates on beaming service, the phone seems fine now. Maybe uninstalling the updates of which apps are draining the battery could help you guys as well.

ive tried that before but after fresh install. beaming service could no longer be disabled, nor its updates uninstalled.
Besides other apps are also draining battery like AASAservice, settings, device maintenance, etc.
I received an update yesterday for the CRC7 March security patch.
Battery life aint any better

You're right, that can't be disabled but I was simply able to uninstall the updates by clicking three dots top-right corner of app info screen. I've the latest version CRC7 on the phone by the way.
Hello !
I've been s8 for three months and I've never had any particular problems, I've upgraded to CRC7 (second update of Oreo) and I've already got twice the phone with a flat battery:
last week in the morning I found it at 1% from 35% the night before (during the night only the gsm network was active, everything else off); when in doubt I did a factory data reset by installing only minimal applications (FB, whatsup and little else) and I installed the Accubattery application to monitor the battery.
Last night put away (active gsm only) at 65% of residual charge and this morning after 10 hours it was 5%: 60% of charge consumed in one night.
Android does not report any abnormal consumption of any application .... it seems an anomalous battery drain
I enclose battery data screenshots; is not that the new Oreo update is buggy? or could the battery or the phone power circuit or the radio part that consume excessively might have a problem? Before bringing it to service I wanted your opinion and in case I wanted to try to put back the CRB7 version of Oreo .... how do I do it? do I lose the guarantee in this case?

i'vre tried with beaming service but clicking three dots top-right corner of app info screen not available for this app : three dots top-right corner are for all the apps
Do you have a drain simillar to mine ? Help me please !!

I have the exact same problem as you and many others. I have tried various things to solve it and I concluded on that the modem firmware has a serious bug . airplane mode consumes more battery than on cellular. To make sure we are talking about the same thing please try removing your SIM card and let it all night . By the morning you have to be -2% of the battery . With the SIM inside now you have to drain 15-20% . If thats the case for you , you make sure that its not a faulty device and there is no drain from your setup (like an application draining etc .. in this case factory reset should fix it).
Cinfirm your findings and lets hope they will release update soon.

he doesn't do it every night, but random : in a week it happened twice
It's not in airplane mode, modem is switched on only for phone line (LTE off) ; I already tried two factory reset
Yours is affected only in airplane mode ?
Tonight , my s8 have to drain 60 % in 9 hours !

It drains in general but while in cellular it's difficult to distinguish if it's a bug or bad signal . Each ones phone may consume different amounts of energy depending on coverage etc. But in airplane mode you can be sure it's a bug because antenna transmission should be off and therefore not consuming energy . Just try as I said just to be sure we have the same issue . One night with airplane mode and SIM card in and another night airplane without SIM. You should see great difference .

Tonight ( gsm on ) have no drain : 0,3 % / h. ( 3 % in 10 hours ).
if it is faulty the battery should always do it?
Did you try to see if it drains, leaving the radio part active?

This will not help determine the bug because as I told you it's signal dependant. It's 3% in 10 hours because you probably had good signal . Else it could be more and even if you contact a service they will say it's not a bug but the signal . Anyway if you were with data on and 4g seems more than fine to me . Now if you try this night airplane mode for 10 hours it could drop 15-20% ... is this reasonable ?

in airplane mode is a bug, but a 60% night-time consumption with active gsm?
0.3% / h. the device was in the same position the night before when it consumed 60% in 9 hours

Your case seems more like a random application wakelock . Did you do a reboot between the 2 nights?
To distinguish better the cause of the drain , when you see an abnormal consumption try removing your SIM card for a while . If this fix the drain it's the buggy modem/radio firmware ...
