Battery life getting worse, common problem?

Yesterday a post was made to /r/nexus5 on reddit about how battery life was getting worse as time went on. Over 100 people replied saying that their phone was getting worse battery life as well. Here's the link: http://www.reddit.com/r/Nexus5/comments/1yxj2g/battery_life_went_from_insane_to_terrible/ The most people were able to find out was that there was a problem with the Android OS process. Are you guys having similar issues? And do you have any fixes?

Batteries do lose their max charge over time. We're now 6 months aged for the first purchased devices, so it could simply be those batteries are starting to age. They still have years to go, but a brand new battery will always be impressive.
It's one reason why I silently laugh at people bragging about great battery life for a brand new device. of course it will get good life, it's a new battery running optimized software that isn't pushing the hardware as hard as the software 2 years into a device life cycle.

posted by people that know nothing..
as time goes on, you install more and more apps. many apps arent coded very well, and have other issues. anyways, people get more and more of these crappy apps that will drain more and more battery without you even using them. anywho, not a problem here. i get pretty much the exact same battery life now as i did months ago.

great battery life for an "old" device, 5-6 hours screen on time every single day. the batteries life doesnt reduce that quick, and generally youll change phones(within 2 years) before you see the life of your battery shorten.

6 months isn't going to be noticeably less max charge unless the battery was severely abused. Also the phone has been out for 4 months and most are younger.
Here's something to think about: Usage patterns change. People install new apps.

Indeed usage patterns play a massive part. And some of which can be completely out of your control.
At home on WiFi I'll get 6-7 hours of screen time.
At home on hspa I'll get 5-6
At work on hspa I'll get 3-4
So at worst case scenario I can lose half of my normal battery usage just based on the carrier performance.

I get about 3-4 hours SoT daily... If anything, that has gone up since I got my device (one of the first batches shipped in US).
I wish I could get 5-7 SoT, with numbers like that, I'm beginning to think I'm doing something very very wrong
Point is... I have one of the first phones shipped out, and my battery life has stayed exactly the same.

High battery usage by Android OS is probably good indication that there are some wakelocks. It has nothing to do with battery being "older".
My battery is great from day one.
Captain obvious mode now:
Posting SoT is pointless and proves nothing. It really depends on what you are doing when screen is on. It is really obvious that it is not the same if you read some book with 5% brightness or play a game.
My SoTs go from 2h up to 7h, depending on usage...

wake lock is main reason makes battery drains so much. try to use greenify to hibernate apps.

LOL. Yep. Give me a day and I'll show you screenies of ten hours of SOT. It'll be BS because to get those results I have to set my phones brightness to less than stock. I also have to set screen timeout to 30 minutes. As well I need to remember to turn the damn screen back on after 30 minutes. I also have to make sure my phone is in my sock drawer doing nothing when the screen is on. It'll still show 10 hours SOT though.

Only 10? Think you could do much higher in those conditions.

Yeah, the common problem.... My battery just is used for 5 hours.
But there are some fixs to follow:
http://forum.xda-developers.com/showthread.php?t=1168036

I posted my usual screen times on a typical day for me.
Typically I do the same things which are a lot of xda and viewing the verge and YouTube. A few calls and texts.
And from my experience the difference between being at home with WiFi off and being at work with WiFi off is that my battery usually lasts nearly twice as long at home.
I was trying to get across the message that your carriers signal strength plays a massive role on how long your battery lasts.
So say if a mast went down and you get bumped onto one a bit further away (they don't rush when fixing these things unless it's a critical one). You would have done nothing and all of a sudden your battery life has started taking a massive hit.

I'm also having this problem with the android os draining my batter And this started happening within the last week or so.I used to be able to easily get about 30 hours out of my phone, now I'm only able to get about half that. As you can see in the 4th pic, android os has been the cause of a 3h45m partial wakelock, which doesnt seem right to me and is probably the cause of most of the battery drain. the last 2 pics are something that also seems weird to me, as google accounts manager shouldnt take 4% in about an hour. I dont even know why its running that long. Though i know how to quick fix the account manager drain (simply disable it) the android os isnt that simple as i dont know how to see exactly what apps or processes are making it cause a partial wakelock.
Im on omnirom using chaos kernel 9.2

I had a similar issue a while back, and in the end it was Google location reporting within Google now service. Try to switch location reporting off but leave location history on and see if it helps. Also choose Location mode to battery saving.
Turning off location reporting does not affect Google Now functionality...
It can be something else in your case, but this problem was common...

One thing I've noticed as a weirdness is the cache of a phone can get stale and so it gets into some weird loop that drains battery or something and clearing the cache improves battery life. Also sometimes apps can develop bugs or new wakelocks when you do an update so sometimes you have to stay on top of it to track it.

If I did not use some preventative measures to prolong battery life I would maybe get 14-16 hours in a day of usage, I always left wifi on, bluetooth even when not connected, data, force LTE, etc. I did not care because I charge my phone every night. I just find it silly if I get a day usage out of my phone and it is at 50% well assuming you use the phone the exact same as the last day you will use another 50% and it will be dead by the time you get to your charger.

S10E stand-by battery drain. Let's get on top of this.

So, I have a Exynos variant of the S10E and I'm having mixed result with battery life:
If I use my phone a lot (and I mean a lot) for example when I'm traveling i get about 6 hours of SoT which is great with a 3.100mah battery and heavy usage.
However on a regular day the phone just seems to discharge itself when in standby mode and I don't even reach 3 hours of SoT.
My setup is simple: all apps are disabled when on standby except for WhatsApp, Telegram and some e-commerce stuff and in the Battery stats "Android OS" in on top of everything (except for screen).
Are you having the same issue? Did you manage to find the cause? Let's discuss it.

This solution was posted on the S10 forum and certainly helped me.
There's a bug that stops the phone from going into a deep sleep mode post making a call (audio/video) on apps like WhatsApp, Skype et al. The solution for the time being is to reboot the phone once before going to bed. I tried a lot of other things but had a ~2% hourly standby drain which reduced to <5% overnight after figuring out this solution. I have both WiFi and Bluetooth on at night.
You may try to play around with the battery saving tweaks in ONE UI but nothing worked as well as this has. Hopefully there'll be a more practical fix to this soon.
Cheers!

Hi! Thanks for your feedback.
I have my S10E scheduled to reboot every night but this doesn't seem to fix the issue and I also don't use whatsapp/telegram voice/video calls, so I don't think is is quite the issue.
There's probably something else preventing deep sleep, but I think that waiting for an update from Samsung will be my best bet

That's interesting. There are over two dozen people on the s10 page confirming this to have solved their drain.
For how many days have you had your device? Mine took a while to understand my usage pattern
I am currently getting over 5 hours SoT over 18-20 hours now, it was ~3 hours previously.

I'm having the same issue. No video calls and still losing ~2% per hour. Restart doesn't help.

Mine too, lost 3% in under an hour sitting in my pocket doing nothing. As usual the battery stats are not much use.

There's a bug with the proximity sensor. The phone gets turned on automatically in the pocket which might cause battery drain.
BTW putting the phone on battery saver (Medium power saving) mode stops battery drain. Until we get a fix from Samsung this seems like a worthy option.

Nope. It's not only when sitting in the pocket. Basically put it on a table and the battery will drain.

There's people on the S10 forum reporting a much better battery performance after a software update (ASC8) on the Exynos S10 / S10+ (see here or here) that should fix the drain issues. Do you know if they are rolling it out also for the S10e Exynos?

It seems ASC8 has been stopped, and they are releasing ASCA. For now it has only released for Germany firmwares. Let's see what's new in this update. Regards

Same issue
I have the same problem, when phone is in use it gets great SoT of around 6 hours, but when not in use throughout the day battery still drains very quickly. I was hoping the update will fix it , but even after updating, nothing changed. Hopefully there is a solution soon.

Seems like battery drain issue was fixed in the latest update ASCA. Mine was previously draining 15% overnight. Now it only drained 4% in 8 hours!! Which is pretty amazing.

Anyone have the Hong Kong model G9700? I've noticed standby drain is quite high.

I have German ASCA version, but battery is draining awfully. I use both SIM cards and loose 25 percent half a day being in standby-mode.

Expected at least 5 hours of SOT from a phone at this price point. This is bad. Even with the second sim turned off, battery drains heavily.

I was also having pretty bad battery drain, 15% overnight. But after the ASCA update I'm getting about 5% overnight, maybe it's just my phone?

Used this guide:
https://forum.xda-developers.com/s10-plus/how-to/galaxy-s10-battery-optimisation-guide-t3911988
After i made the tweaks the standby is decent compared to my OP6

I disabled bixby on the Maine screen 4 hours ago and I do have a feeling my battery od much better. Will see...

ASDA update seems to help with drainage for me.
Using 970U1 TMB version. Attached is typical usage for me last few days. I get another 6-8 hours sot average by 15% or so and about ~5% overnight drain

S10e Weird 999:MAILBOX_CP2AP Wakelock
Not sure why the "Android OS" always so high usage, I think in normal case, it should be lower than "Android System"..
And by using Battery Historian, I saw this kernel wake up, does anyone knows what's that?
I'm having a lot of RILJ_ACK_WL too.. Sigh.

Note 10 Plus bad standby battery drain

I've had my AT&T Note 10 plus for over a week now, and for the first week the battery life was stellar. Three days ago seemingly out of nowhere, battery life had tanked. Some context - I came from a Note 9 which had fantastic battery life. Location on, widgets, notifications, etc were enabled. I feel I shouldn't have to yield to or cripple my phone to get decent battery life from it so I refuse to do that on a device that costs this much. It should just work.
Anyway, fast-forward to three days ago with my note 10+ - same settings and everything as my previous note 9 - and out of nowhere the battery life just starts to tank. Android System is seems to be the drain, but I'm not sure what in there is causing it. The phone is constantly warm. As an experiment, I've put it on airplane mode now with wifi still on and the phone has cooled down but I'm not sure yet if the battery is being drained less or not as it's only been a few minutes. But, I am losing about 6% battery/hr not even using the phone. That is rather unacceptable after it having worked just fine the first several days I've had it. I refuse to disable location and do other seemingly band-aid tricks to help the battery along as I don't feel that really solves the issue and should be unnecessary for a device that costs this much money. I also refuse to factory reset unless I ABSOLUTELY have to because these phones are a pain in the rear to setup, even with Samsung/Google's restore. So many settings to go in and manipulate.
I hope this resolves itself or I can get to the bottom of it somehow. I really love this phone and really don't want to go back to my iPhone XS Max over a battery issue but it is just unacceptable for the battery to drain like this with little to no actual use of the phone. The other night by the time I had placed it on the charger, android system was up over 30%...
is anyone else experiencing this problem?
I apologize if this has been discussed before - I couldn't find anything similar.
EDIT
After putting the phone in airplane mode (wifi left on), it has cooled down and battery drain seems to have improved. According to the battery graph it looks like the phone is also finally going to sleep. Previously the graph went straight down to the right with no flat spots.
What could this be? My cell reception hasn't changed and I'm at wit's end

I use Naptime from the play store by Francisco Franco and no as the title of his app says you don't get 9000% better battery. You'll need a couple of adb commands to get it to work it you're not rooted.
https://play.google.com/store/apps/details?id=com.franco.doze&hl=en
This is a quote from Franco - Unbelievably improve the battery life during idle of your device by empowering Android's built-in Doze power saving functionality. It supports Marshmallow, Nougat, Oreo and now Pie. It features more options for rooted devices, but it'll also work if you're unrooted.
Naptime also allows you to disable WiFi, mobile data, location & bluetooth during doze for that battery life /flex ?

I find that I'm losing around 1 to 0.7% per hour is that normal or considered good? The other night my phone was at 95% I woke up 6 or so hours later and it was a 89%. I'll need to do some thorough testing, but I don't know what to make of those results.
Anyone on here have some advice on weather that idle time is good or bad? My device is an unlocked n10plus running Snapdragon

-If you charge to 100 and put it next to your bed. How much is it next morning?
-do you use the led cover?
-are there any less known apps in your list?
Switching off wifi, Bluetooth etc is useless. These are efficient enough nowadays.
I tested these kind of "tricks" and no difference after my nightly sleep test.
Sometimes an app like evernote, google foto's or journey is downloading a lot of data in your new phone.
---------- Post added at 02:06 AM ---------- Previous post was at 01:51 AM ----------
With all my last Notes I get a .6 till .9% per hour in a situation where i put my Note next to my bed and do not touch it during sleeping hours.
I live on three different locations, in different countries even, and that shows some battery consuming difference. Routers and provider locations are not the same.
I have more than 180 apps installed. No games however.
I am not rooted, but use GSAM battery monitor. The quickest way to see the hourly consumption.
Factory reset means a full day work for me. E.g. banking apps need a lot of tuning. Even using Google and Samsung restore.

I charge it overnight while I'm sleeping. No lesser-known apps installed, no LED cover either. Not rooted. this literally happened out of nowhere after days of it being great. Not sure what could have happened, or if it's something on ATT's end? I don't know where else to look. I'm with you on the factory reset. It's such a waste of time and will take up hours.

mine also been facing this battery drain issue since day one. Tried using naptime just now and it improve my battery life ALOT!! Thanks for the suggestion

Pls try to charge it before going to bed and leave it to see how much it spends overnight w i t h o u t touching it. If it is higher than 1+%/hr something is wrong..
I buy a new phone every year because I am nuts. But I always register in Evernote my findings.
Frequently the power consumption is higher in the beginning, because a lot of background activity like data reading and background update of software.
If it is more than, let's say 1.2%/hr during overnight sleep it is not ok.
I am doing this test now with my Note 10+ 512 (Yes i am nuts, I told you) and will inform you later.
After seven hours .8%/hr which is normal.

I can tell you right now that it's losing 5-6% an hour just sitting there. The phone has been set up for days now so I know it's not the setup process. Like i said, it was fine for almost a week, then out of nowhere this happens...

Pffff, you have a problem. So in settings/maintenance/battery there no apps with high use?
After just rebooting the phone the consumption starts immediately?

Yes...I know I have a problem...Android System is the culprit. Beyond that, I do not know what in "android system" is causing it. Perhaps a wake lock bug? A wifi bug?

It's always the same with my Samsung devices it's rediciculus Samsung. On your note 10 or note 10+ before switching to flight mode set the network setting to 3g only! In 7 hours you will loose only 2% battery instead of 8 or more. Same was on my note 9 but Samsung finally patched this behavior a few month ago. Now the same with my note 10+.
This problem is only for the flight mode. So you can test 3 things in 3 nights. You have 3 options before going in flight mode. In network selection choose 3g only. Than watch what happens over night. Next time you choose 2g/3g only and you can try it with 2g only.
For me doing so 1-2 % battery drain in 7-8 hours.

I've pretty bad reception with 4G. But no crazy 25% drain over night, more like 4-5%. And that's with the non plus Note with exynos.

With naptime, do you get notifications instantly? I have auto sync on all the time, is there any issues around this?

Just bought a new galaxy note 10 and overnight from 100 % i have 57 this morning. Whats going on?

Is this normal on note 10 plus battery health?

My N10+ is about 3 weeks old, but I found, like you, that after a couple days of stellar battery life my idle was starting to drain pretty fast. Going to bed and waking about 6 hours later I was missing around 20%. This is with all apps closed, WiFi, BT, Location, Link to Windows, Mobile data, NFC, Sync, and AOD turned on. I turned off AOD, NFC, and Link to Windows. My battery drain since, for the better part of 2 weeks, has been about 5-6 percent. Around 1% an hour while sleeping. I don't know how I can help, but I hope this does. I honestly can't complain about this battery. I have been getting 6-7 of screen time before having to charge around 10%.
Edit: also turned off edge lighting, which I had enabled before.

ehm so you made your top shelf 1000$ device into a feature phone ... that's no solution

I don't remember saying, "Here's a solution for you!" No, I simply posted what I did to stop the horrible battery drain that I was experiencing.
Also, I spent the $1,100 on this phone and I'm pretty sure I can use it however I want. Feature phone, paper weight, fish tank decoration..:good:

My N10+ has been sat on my desk and not used for 4 hours yet battery has gone from 100% to 78%.
I don't know how this is acceptable.

I have the reg note 10 and ive been battling this for a couple weeks. nothing seems to keep the system from sucking the batter dry. Standby life is a joke. i lost 40% today with the phone on for about 10 hours and 30 min SOT while i was at work. I cant figure out whats stuck in the system, tried literally everything

Question New Poco X3 Pro - defective battery?

I've ordered a Poco X3 Pro directly from the localized Xiaomi online shop a few days ago and have received it on Saturday.
It arrived with the battery at 72%.
After setting it up, downloading and installing a new firmware version, installing a few apps that I'm using as well as uninstalling several of those that came with the phone (all done only with the phone itself - no adb debloating, yet) I put the phone aside with I think around 45% of battery capacity left. (Possibly something around 35%.)
Just now - about a day later - I picked it up again to continue and am shocked to find out that the battery is completely drained. (I haven't even put a SIM card in, yet)
Does that mean that I've received a defective device or is there another plausible explanation why the battery has completely drained within just about 24 hours at the most of not even touching it?
Could it be the not having a SIM in while NOT in airplane mode or is the modem off anyways when there's no SIM?
I'm hoping that someone in this subreddit can give me some advice on the issue.

It means you should charge a new device to 100% before using. Charge to 100% then use it until shutdown for 3 times and see what you got.
It's best to establish a baseline before optimizing. Otherwise you have no frame of reference to the performance improvement or degradation.
Return it if it doesn't function normally.

if the problem persists bring it to sc or for replacement.

Thanks to the both of you for replying.
In the meantime I've fully charged it and put it into airplane mode with wifi on (its not my main phone, yet, so there's still no SIM in it). Now, two days later I'm still on 64% charge.
To me that either points towards the new battery having to be trained first issue or indeed is an issue caused by not having at least one SIM in causing the modem to go on continues search draining the battery. Had I better battery stats on the phone I could test that latter theory - unfortunately I haven't.

try using it with sim and fully charge it 100 then use as normal with wifi or just play games, let's see if how it goes.

See what app(s) is using up the battery.
AOD is off, right?
Otherwise that's a high drain.

does our unit have aod? hmm. maybe it's because of running apps or android setup

Just saying... if not standby time should be very long. Likely an app.

Poco X3 Pro is LCD, no need AOD.
MIUI system itself drains battery fast.
Personally uses custom ROM. Whole day with 3G only, WIFI off mostly, phone mostly in standby, battery drain is around 5~6% or less per day.
Stop charging at 55%, start charging at 49 and below, charge once daily.

I wouldn't mind lineageos but I have to use an official ROM for my banking app to work.

I see

Just a heads up:
After little over three months of using the phone I've come to the conclusion that the issue was caused by using the phone without SIM while it was constantly looking for a connection. Putting it into airplane mode fixed the issue.
Once I had fully swapped phones from my Axon 7 to the Poco X3 Pro (i.e. also moved the SIM over) it still worked as originally expected.
Now, since I currently can not sit due to a few surgeries a few weeks ago I'm fighting boredom in bed with the phone watching videos, surfing the web, checking some apps or by playing games via the Steam link app. So wifi and Bluetooth are both on all day every day, not to mention the normal mobile network connection.
With doing that I would guess a full charge would last 12-13 hours because typically I'm charging the phone before I sleep at which point I'm down to about 20% and having a full day with around 10.5 hours of screen on time.
I can only say that I'm really satisfied with the battery life of the X3 Pro - so far there's nothing to complain (besides a lack of updates and MIUI 12.5 which although ok isn't my favorite).

Question Huge battery draining

Hi all! Hope I can have son help from anyone... I'm experiencing a huge battery drain on my watch 4 40mm... Usually battery for me lasts around one day and an half, but right now I can't barely complete a day. Here's my screenshot on my galaxy manager app.
I saw the thread about Google Assistant draining battery a lot and I've already disabled it since I'm not using it. But as you can see in a little more than 4 hours by battery has drained a lot...

You will need to supply a lot more info. Like what settings you use, especially AOD, how often you use it and what you use, how old the watch is, how often it is charged, etc.

Sorry you are right.
Aod always disabled.
I have the watch since 7-8 months.
I'm not using the watch really hard, just to see and reply text messages (not so frequently) and track my sleep during the night. Wifi always in automatic mode. Localization disabled.
I was used to charge it once every two days usually, now two times in a day...

I would start by using either command prompt or adb app control to debloat the watch and see if that makes a difference

how many times a week you restart the watch?
i think is full, close every app and restart the watch then try to use risparmio energetico (you are italian vero)

Here is my stats. This is ofc with multiple charges. I have the same 42mm Watch 4 classic with LTE. Normally it does not last even a day.. If I enable battery saver it last 1 and a half day. So you can try that? My watch 3 46mm lasted around 3 days lol..

Hello, I have had the same, suddenly barely getting a day out of the watch with no change of settings or face etc, many on Reddit say the same too.
https://www.reddit.com/r/GalaxyWatch/comments/w9f923
Hopefully just a dodgy app update that will be corrected in the next update but very frustrating, ~I have turned off "raise to wake" today and I'm still on 50% which is about what I would have normally had at this time of day before this change.

I'm really hoping the problem is just a crappy update honestly

If you have already performed a factory reset and the problem persists, then I wonder if it could be a bad calibration on the battery, or hardware failure. Chances are that it is something else, like you mentioned -- a bad update -- but it is possible that the device "thinks" the battery is draining faster than it actually is, or "thinks" the battery is fully charged before it really is. Just something to consider.

And if that is so, it is easy to fix. Just charge to 100%, then allow it to run COMPLETELY down to zero charge (just use it normally) and it shuts off. Don't use battery saver. Then charge it up 100% and do it again. I have done this with phones before to fix calibration.
Remember, Lithium Ion devices don't really know the state of the battery completely. There is a lot of guess work going on. But this calibration usually fixes the issue where it thinks there is MORE battery available than actual, not the other way around.

Yesterday I had a Health Services update on the watch and it seems to have fixed my battery drain problem, hopefully you have the update already or soon.

I done that Health update last night and it drained 30% overnight, I'm hoping a cache clear, reboot and full charge this evening will sort that out, they fix one thing and break another!

This is not encouraging me..
With my old galaxy watch 1, in the entire night with sleep tracker on, it was losing 2/3%... this watch lose 15/20% in the same hours... maybe depending on OS used, but it's really strange that a 3 years old watch is better than a new one... I was charging the old one every 2/3 days, this new is impossible to achieve 2 days..

Yes, I too had a GW1 but I believe that Tizen was much more optimised by Samsung as it was their own OS, still disappointing with the consistency (or rather inconsistentcy) of Wear OS3.
Hopefully the next version that is currently in Beta will be more optimised and bug free.....

Don't ask how..
But after 1 month and a half, I've reached for first time 2 entire days of battery.. nothing changed in last days, except aod off. But 3 days ago I returned home with 54% of battery after 22 hours from charging and aod on, while yesterday with same hours and aod off I was at 62%, so not a big difference... maybe some minor updates of some apps? Someone other noticed improvements in last days?

I have a somewhat long story but it may help some of you here. I was wanting more complications on my watchface for more info and finally when I was annoyed enough that I couldn't find a watchface with how many I wanted, I went to work with watchface studio only to waste a ton of time making it look just like I wanted only to find out that there is an 8 complication limit on faces. So I started looking for alternatives and found bubble cloud launcher. A replacement launcher and watchface for wear os. After the steep learning curve that came with this AND emailing the dev back fourth a bit with questions. I found that using his watchface and his liveinfo (what he calls them) bubbles instead of using complications I get WAY better battery life WITH more info on my watchface than ever before. According to the dev, his liveinfo bubbles update dynamically from the phone companion app and not just whenever the watch wants to, he said that during his time learning about watchfaces that some complications update every second and others every minute and some are really bad on your watch battery and so when he designed his app he had battery longevity in mind and boy does it help me.
