[Q] Are the battery drain issues with ICS fixed yet?

Hey there,
In case you can't tell, I'm a newbie.
Anyways, I'm currently using a 6-yo HTC Dopod Pro and I've finally decided to get a new phone.
I really want to get a Galaxy Note but I hear that the Note has a relatively short battery life.
I also heard that ICS for the Note causes the battery to drain even quicker.
Have these issues been fixed yet?
Cheers.

What you have heard is misinformation. A bad installation of ICS, rogue apps and weird settings are the cause of people having battery issues with ICS.
The Note has one of the best battery lifes among all android phones.

Note has excellent battery life. I have the LQ2 ICS, and I have no weird battery drain, wakelocks or any other probs

Just disable some draining apps on ICS.
Don't forget the huge power of note battery( 2500mAh)
I'm also on LQ2 ICS =]

Really?
Cuz I hear lots of things about bad battery life on ICS, even on xda.
Some examples:

I heard the battery life was pretty good whilst on GB but as soon as people upgrade to ICS, the life was substantially lower.

The battery drain "problem" of the GNote is like troubles with your Windows computer (IMHO): The more you fumble, worse it gets. Use it as it was designed and you'll be a happy person.
I have a GNote for a few months, it was Full Stock under GB and now is Full Stock under ICS. I use it moderately (2nd phone) and could easily manage 36 hours.
I pick it of the charger ~5h30, 6h00 in the morning and find it at 60~70% when I get home about 12 hours later (30~45 minutes talk time, not much else). I than read my favorite blogs and news papers that runs it down to 30-40% (reading takes about 1,5 hours).
When I go to bed it's never lower than 27-30%
The only problem I have is that it sometimes doesn't go in Deep Sleep and that I solve through a systematical reboot in the morning (of the charger).
As always (even people) the GNote is as good as you treat it

Hey Little Vince
Welcome to XDA!
I have had Note for over 6 months (bought from UK to Brissy) Been on ICS only last eight days or so - and I can report that the battery life is slightly better than GB. Speed is better too - not as much lag.
I have used Blackberry/Axim/Palm before and always got into the habit of charging overnight so anything longer than 24 hours doesnt really matter.
Please don't let others put you off a wonderful phone. It is so versatile.
PS - it always takes a few battery cycles (e.g. three or four days) before you get accurate info. I have had quick battery drain for a few hours after updating Kernel but it always settles down.

What is that systematical reboot you're talking about? Can you explain a little bit?

There are a few tricks suggested in this thread http://forum.xda-developers.com/showthread.php?t=1649041
I found my battery life was quite poor at first but it has improved after a few charging cycles. Also, I had a lot of syncing processes running (some duplicating others). Killing some of those also helped.

Never had an issue with batt drain, either on gb or ics... I think the latter is a bit better. I leave gps, wifi and 3g on all the time, and am a relatively heavy user... really haven't tweaked anything for batt life, other than removing some bloat.

OP, it would probably help if you told us what you would consider to be decent battery life. That way, people will be able to tell you if it is possible.
As for me, I'm on CM9 and have never tried stock ICS. I can confirm that battery life was better on GB, but CM9 still gets me through the day on fairly frequent use.
Usually fully charged when I get up in the morning (6am), and down to about 20-30% when I charge it at night before bed. This will normally include roughly 3-4 hours screen time from watching movies on the train and internet browsing throughout the day.

Same here no battery problem. I'm using DXLP9 firmware.

Nah battery drain is a real issue with ICS. It's too documented to be denied. Doesn't matter what I think is good battery life, but relatively with GB, it was 20-30% for about 12 hours of use (wife doesn't use it much) and after ICS, it's -110%. Hmm.. I meant for the 12 hours, it needs a charge and then some. And that's crazy since my wife really doesn't use it much.
Anyhow, this completely fixed it for me. Looks like there's a few bugs that you can come across if you have battery drain with ICS. Check the full thread for more details...

UPDATE: ok no. Still no real solution for fixing this after trying many over lots of days. AFAIK, kernal problem that Samsung needs to fix. And please do fix!!

As I see it from the times from BBS the problem of the drain is at standby mode where the battery for the start of locking and outing on sleep it eats slot of battery till it reaches the 1% every 1 hour and 45 minutes like it was on lc1 stock, even I had on GB 2 hours 45min for 1%, it starts with 1% for 30 minutes then 45 min 1 hour and so on till it reaches the max of it.
The use with screen on is the same 25% for 1 hour and 20-30 min screen on time with low brightness, as it was with GB. On GB I had 5h30m screen on with 10-14% battery left.
So the issue for me at least, is the standby aka sleep mode.

to the OP, yes battery drain is a documented issue on ICS, with the wake locks and rogue apps (for the unlucky few.. myself included)
i was on rooted stock GB and i used to have a good 72hrs of standby time for the note especially on the weekend when it is rarely used and maybe a good 48hrs on a weekday with average usage (about an hour's call, moderate surfing, facebook etc)
during days when i travel a lot i can be surfing and listening to music and doing calls for the better part of the day and the note still lasts a day with about 20% juice left by 7-8pm
however after I upgraded to ICS LP9, my battery couldn't even last me for a day without getting a few hours of charge from my laptop, i was on stock ICS for 2 weeks and did a lot of fine tuning just to optimize the battery life and ensure the phone goes into deep sleep and still not sufficient. the thing that blew it for me was when i noticed that my note started running at 1000mhz only and not any lower (even when charging - take note i was on unrooted ICS).. so decided that ICS with all its hype wasn't polished enough yet and was not worth it for me and went back to my stock rooted GB LC2
now i'm a happy camper.. note sleeps like a baby when it is supposed to and runs smoothly when called upon
so to answer your question (sorry about the long story) yes you can enjoy great battery life on note be it GB or ICS but you won't know until you get one for yourself.. and like what the other posters said the note is such a beast of a phone that you will not look into another phone again once you get one be it on GB or ICS

I absolutely would not recommend the G Note until there is another ICS update issued - unless you want to stick to GB (in which case I would definitely recommend).
Apart from the deep sleep problem, which for me anyway, cannot be resolved, I've had stability issues, overheating and it even pulls restarts without warning.
The only battery fixes that have kind of worked for me (and they still don't get me anywhere near the battery life I was getting with GB) involved me following a 5 step programme every time I charge my phone, which is frankly unacceptable.
FYI - I've had the note since December and it's running stock everything.
The Note is an amazing phone, but ICS has rendered mine not fit for purpose.

The sad thing is samsungs and android capabilities in finding the culprits. Fancy native battery charts which dont help much, if any in analyzing.
Only best case is to check deep sleep(cpuspy) , and if deep sleep is low check partial wakelocks in betterbatterystats.
Then you can find a lot of the culprits
Good thing the XDA community picks up where Samsung/google drop the ball.

To the OP. My Note on gingerbread had wonderful battery life 16+ hrs. After the ICS LPY update my note dies after 5 hours. To all the naysayers saying there are no issues with battery life on ICS, give me a break. Just google how many note and galaxy SII users on ICS are having battery drain issues.

I get exactly the same battery life on ics that I did on gb, the battery drain people are having has nothing to do with ics. It will be apps causing the issues. Im running exactly the same apps as I was before and its exactly the same battery.

mmm.... No.... The same apps, even after a factory reset and reinstalling apps I STILL had the drain. You say it's apps that aren't optimized? That could be true... but then again, I guess it must be a VERY VERY common app that's causing this because most everyone says they've experienced a decrease in battery life.

Performance and Battery in JB.

I was wondering. I looked everywhere and cannot find exact confirmation or Review. The 4.1.2 update is coming soon for the Optimus 4X and I read on 2-3 blogs that it'll apparently improve battery life. Is that true? Has anyone tried that themselves? From what I observe on my 4X that there are a couple of apps running in the system sucking up the battery. Will the future update fix this to extend its life? Sorry if this question was asked before and/or I've made a double post.

I'm an average user... Not much into games but I message a lot and play on YouTube use wifi and phone regularly... This is much improved for me over 10x

One day+?! Holy-- yeah that's surely an improvement to what I'm experiencing now. Is the phone running smoother as these blogs say? Any crashes/freezes or its a perfect charm. I'd just want to know what to expect...
Also, I've noticed that my phone tends to warm up from... almost everything. Is it still happening?
Edit: Sorry about this post... I rushed on asking this question without realizing that there's a Q&A section.. is there anyway to move the post? If not then I'll delete it.

Disabled them as in uninstalled them? And wow.. yeah that's surely a lot better than now. Better then my last phone.

My battery is still the same as that in v10f. I get about 3.5h of screen on time( mainly web browsing ) to reach 10%

How is the overall performance?

Depends on what you think is important. My phone is my "phone". I expect it to be as such. I can't imagine Web browsing for 3+ hours on my device. My Dell mini is better suited for that task and has better then 3+ hrs battery life. But maybe if your a gamer or a Facebook addict or Web browser cowboy, you find like people that use their device in the same manner as yourself and then compare notes.
Because of my job I'm often on the go and don't have the opportunity to recharge my device at leisure. It's nice to know it can be used as a phone all day and I'll still be able to call my wife at the end of that day. There if definitely improved battery in 20x after a few services are disabled and be r uninstalled. Prior to leaked JB my device required recharge after i got home. This is how I use my device and the condition under what I use it. These are my results but your milage may vary.
Yes the interface experience for me feels silky smooth. No lag, and no crashes or FCs. Best device I've owned to date.

its not specificly the browsing he did that makes the post usefull unlike some people posting battery charts its the fact that he posts screen on time rather then the chart.
the full charts are useless as you cannot see how often the phone was actualy used.
if i link you 2 charts 1 with slow battery drain in standby and no apps used at all (no screen on time) lasting 2 days exactly and 1 with near no battery in standby and 4 hours app use.
they both look the same if you post a battery chart but only the second one shows the potential of the battery life.
the first just shows the phone needed to be charged after 2 days the second showed the phone is capable of lasting 2 days with near no idle battery drain and gives a verry descent 4 hours screen on time.
a phone that is configured correctly and had good 3g/wifi signal and has 3g/wifi managed correctly, has no apps with adds and no apps that drain battery wil berely use any juice in standby leaving almost all the juice for screen on time.
a badlymanaged phone might drain up to 10% an hour because of adds and poort wifi/3g management/signal.
so in a perfect world (which we should aim for) only screen on/inapp time is important as there should be no other power hoggers.

Those on Lollipop, has battery life changed?

One of the key features of Lollipop is Project Volta, which is supposed to improve battery life, specifically standby time. I know the update has only been out a few days, but for those that have it, how much has your battery life improved?

It seems drastically better for me. Enough so that I'm going to keep the phone after thinking about getting rid of it after early battery life underwhelmed me. Where I used to finish the day at 10% or so, I'm now closer to 30-40%.

What I've found is that L without Greenify has battery life like Kitkat did with Greenify. Now that we have root we'll see if greenify makes it even better.

It's been a solid improvement for me, at least when I'm connected to wifi and the phone isn't being actively used. Probably only losing about 1% an hour now, as opposed to more like 3% before.

Project Volta optimizes battery consumption but app developers have to support the APIs, see here:
https://developer.android.com/about/versions/android-5.0.html#Power
So, basically, Google and Motorola apps probably already use this, but battery life will not be so much better until app developers introduce support for these APIs

Battery Issues
I may be in the minority here, but my battery life has significantly decreased since the update. I don't have specific figures but I do know that on normal usage, whereas my battery used to be at about 70% after approximately 4 hours, it's now down to about 50%. I suspect it is due to some apps that are not optimized for 5.0 that are restarting again and again in the background. Either way, I hope this issue is corrected because I am having a hard time walking away from the charger for very long.

Mine is much better then before on KK.

After updating from KitKat to lollipop 5.0.1 I am very dissatisfied with the battery.

Hello all, I am assuming other people have had this issue, but are there any roms out there that fix the battery life between the KitKat and Lollipop updates? My battery was amazing at first, I could come off battery in the am, and still be at 95% around noon to 1pm, but now it drains about 20% faster it seems (wild guess, but I very much do not like it.)
Let me know if anyone has come across a rom that has the awesome battery as KitKat had, otherwise I might just try and go back to that.
Thanks!

I'm currently finding myself in the same situation as you. I've been on 5.0.1 for a while, but my battery life has been pretty bad. I just haven't bothered to do anything about it until my son got a Moto G and can get 5.5-6 hours of SOT, and I'm struggling to get 2.5 lately.
I installed CM 12.1 nightly last night, and so far, it may actually be worse. I can't keep it anyways due to music playback bugs.
I was on TEKXodus N4 URv3.6R3 prior to switching. Like the ROM (as much as one can like a TW ROM), but didn't deliver battery life.
I actually came here tonight to read up on the KK downgrade routine and find a KK ROM and start that.

Well that is unfortunately not what I was hoping to hear, but it may just be worth downgrading. I do like the aesthetics and such, especially of 5.1.1 which I have on my Nexus 4, but I much prefer usability and battery that kitkat provided.

I'm sure I'm not alone in saying it's possible to get just as good battery life on LP as KK. I think you need to look at your setup, wakelocks, rogue apps, too many notifications or apps that constantly sync over the internet etc. Example: I lose 2% battery over night (8 hours).

Fwiw, I reverted to ank4 based FireKat and my battery life is back to great. 4 hours sot + 8 hours of music via slacker and/or Google.
People say you can good battery life on LP but I never could. I went through guide after guide, and none of it ever did anything for me. I'm also not going to cripple my phone for the sake of battery. I'd still like it to work.

How is Pie battery life on the Note 8?

Are people noticing any improvement or worsening?

It's been a lot better for me

Battery life for me is ok, with the official installed for the last 4 days. I'm upto 6 hrs sot on my usage and intend to leave it on charge overnight to complete any optimisations that may have not been done.
The call screen number flashing bug is still there though, but no other issues for me as yet.

i dont know guys... its lottery? i went down from 7h SOT to 2h... i did full wipe ect... i heard a lot of people that said it its better for them with battery and a lot of people saying its even worse than oreo

I'm having about the same batt life as I had with Oreo, but I've upgraded to Pie 2 days ago, so I'm hoping it will get better in about a week when the OS settles down and I'm done with setting it up. I've always had the idea that after a major OS upgrade, it keeps doing a lot of things in the background, making it use more battery than expected. For iOS this is even verified by Apple, but I don't know about Android.

Im used pie for about 2 weeks now.
For me, battery usage for idle is better, im got better standby time than oreo, but once im start using it, it drop faster than oreo. Phone also feel little more hot than on oreo.
Im got battery leakage last 2 days and then i realised that putting video wallpaper on lockscreen eat the battery alive even screen is turn off.. Its just still played in background.
Im got constant 6 and half hour of SOT on pie and 7 hour SOT on oreo (from 100 to 20%) of my battery. I
Im not heavy user, just used chrome and facebook only. No games.
So far, phone is more responsive on pie but never been lack on oreo.
However, im monitor my battery charge capacity with Aida64, im got 3139 mAh on pie and 3220-3298 on oreo. Its seems its limit to 3139 only now for my phone.
By the way, im used Note8 with exynos processor.

Pretty much the same as on Oreo on my N950N running Pie.

Note 8 battery much better with pie...... Verizon
I was expecting the same like for years new update new battery drain. This is the best a battery has ever done. I use my phone alot I have stopped background data for the battery hungry apps. With device care. I set it to see a week at a time. I only done this with Facebook and messenger and chrome. Even before it's been great for me I hope that all of you get better battery life. I know it's hard to do things when you have tug battery charger.

Pie is a joke don't update you will thank me

oreo it's a lot better, but i use custom kernel on pie, "phantom kernel" and my battery life it's a lot better even better than oreo with stock kernel.

Not bad.

Some people here hating on pie, more power to you, but I've only had one minor bug with the sound "popping" in the "My Noise" app, turning off Wifi during use fixes it. Also, all the benefits such as Good Lock, Bixby Routines and dark mode more than make up for the one minor bug I have. FWIW I am on Sprint and Snapdragon model.

Curious. Considering updating soon. Need help manuals. OTA keeps saying "processing failed"
