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.

[Q] Z3 day old, battery awful

Hey guys i'm new to this fourm i just signed up moments ago basically in search of some answers, so yesterday i brought a sony experia Z3 based on their battery life, there freedom, the quad core processor etc, basically for the nice design blahdi blah. but battery was the seller for me as it was known as the ''king'' of batterys..
anyway!
When i opened my phone out the box and started it, it had around 40% battery which is fine i understand they all come out the box half way charged. But i stuck the phone on charge around 12am and took it off charge 8am for when i go to work, now throughout my day at work i used the phone to look on social media, send a few texts, i don't game on the phone nor do i watch loads of videos due to only 10GB of data, but from about 8am to 4pm i was left with 2% battery, now before this phone i had an iPhone5 which in all fairness didn't last me the whole day it would last me till around 11am if i was lucky. but i've gone through various options (stamina mode) was already enabled btw, but nothings made much difference, i've turned the brightness down to nearly halfway, i've turned location services to battery efficient but this is my statistic for 100% battery..
So! my phone has been on charged since i got in at 4pm, haven't take it off charge and i don't intend too till the morning, hoping this will sort it by giving it a longer charge. but anway! as it stands at the moment my phone is on 100% battery, the usage i will get from it is saying 3 hours.. right? ridiculous. WITH stamina mode enabled i get 9 hours, now it seems 9 hours isn't that bad but my expectations was somewhere near the 17 hour mark. both of my friends have a Z3 and they get 15+ hours without stamina mode i believe. but if anyone out there could suggest what the problem is. failing that i will return the phone and swap it for the same model. i might of possibly just ended up with a duff battery sadly..
Sorry in advanced for the long thread.

Curious. I have my Z3 for 4 months now and I can say the battery is brilliant. There are weeks when a 100% charge give me a 2 and a half day usage (with stamina mode on and 4h 30m screen time). In the worst situations (when I'm using it very heavy,5-6 hrs screen time in a day) a 100% charge last from let's say 8 am untill next moring at 10 am. Anyway look at the battery usage data and post a screenshot. Do you have the sync on/off? What android are you using?

Hi thanks for the reply, i cannot post a screenshot sadly but i can tell you the details for sure. the battery usage isn't telling me anything right now bizarrely, it says it's not available. if i remember rightly i know the screen was taking the most at 37% and the android im using i believe you're asking the software version or something? Android 5.0.2

For example this is a 2 day+ battery usage data I had 1-2 weeks ago... Try a hard reset but backup any personal and important data first.

Damn thats the usage i want to be able to get out of my battery, sadly for some reason it's not displaying anything for me it did earlier but now it won't let me see anything which is odd i must say, but from what i remember is that the screen was 37% then it was the android OS at like 7% no biggie, maybe shall i let the juice run all the way out till the phone dies then give it a full charge then see what happens maybe?

Try some full discharge-recharge cycles. I remember my battery wasn't ao great when I first bought it. But neither that bad as you... Try that and come back after if you have the same issue

Yeah i think that might be the best bet, i'll give it to the weekend before i swap the phone see if i can get the phone to adjust, but failing that i will just get it swapped as it's only a day old. kinda disappointing tho lol as i was expecting it to be awesome as yours is and it literally lasts the same as an iphone would

HTC One A9 Battery life and SOT

Post here your findings with the A9 in daily use; or discuss methods to improve battery life (settings, etc)
How much screen-on time do you get? How long does your battery last through the day, with what type of usage?
Mention also your ROM version pls.
If possible, post screenshot from GSAM or similar app.
inspired by similar thread for the M9 here: http://forum.xda-developers.com/one-m9/general/battery-sot-t3067585
ps: I am in the process of chosing a new phone, which could very well be an M9 or A9.

I'm generally a fairly heavy user and I've been very pleased so far with battery life. This phone and OS have so far been much better at preserving battery when asleep and it charges much faster even from standard chargers.

Well I am more then pleased, and if you use the phone as a game console only and watch videos, then it uses more power, but it is a phone right?

Thanks for replies. If possible, please post numbers (screenshots appreciated).
E.g. how much screen on time in a day, how much % left when going to bed without recharging all day.
+ add ROM version, whether 2gb or 3gb RAM...
you know, the essentials to make comments comparable.
Personally I am still on a 2.5y old One X+ that I want to replace. I don't game but need about 4h SOT (browsing, social apps, ...) without recharging. Today, I need to recharge every day during the day, and I want to put that behind me. In gsmarena battery test, the One A9 scored barely better than the X+, and worse than M9. That has me worried.
/ Updated to add: I also need all day mobile internet on 3g/4g, and 1 hour streaming radio (tunein radio app) with screen off). Maybe in future all day bluetooth for a connected watch? /
Cheers

Thx. I updated my requirements though. I'd been too brief
besides, this thread is meant to collect data from many users, to provide usage examples to all potential buyers

From my experience my a9 battery usage is impressive when the screen is off, but when the screen is on it's worse than hTc one M8
in the M8 the SOT I got is between 5 to 7 hours, and in my new a9 the SOT is 4 to 5 hours per full cycle!
this 4 hours screen I used them in 1 day and half, with all time wifi and sometimes 4G Data when I go out.
I will post Gsam battery stats in the next couple days.

Marshmallow's doze mode works as advertised, with seemingly infinite standby times. But there's only about four hours of SOT in the tiny battery, maybe almost five if you're miserly.

That's about like my M9, which is what I expected with the A9. M8 was way better on battery than the M9.

810 is a battery hog. All that heat is wasted power.
But there's no excuse on the A9. Anybody could tell you a 2150mah battery isn't gonna last long. Would it really have been that big a deal to make the phone 2mm thicker and put a 2500 in it?

Yeah, I agree. Personally, I would rather a phone the same size and the M9, with a 2840 battery, but with the 617 proc. But I'm probably not exactly who HTC was targeting with this device, either.
I was just saying that I think HTC decided that if the A9 battery performance matched the M9 then that was good enough. Once I faced fact that the M8 performance was a thing of the past, the M9 has actually been decent for me, using a custom Rom and flar's ElementalX kernel.

Day 1:
I unplugged my A9 at 7am.
3 minutes of scrolling through facebook. Then drive to work.
7pm the phone vibrates and tells me I have 15% battery life.
I made 4 phone calls all less then 5 minutes. Turned the screen on maybe 10 times to do a time check. And spent a good 15 minutes on break scrolling facebook.
12 hours of almost non use...
Then the fast power dump came.
My 20 minute drive home it went from 14% to 2%.
This is crazy.... I may have to return this thing and get my M8 back.

That battery will definitely be sufficient for the "average user" (by average I mean 9 to 5 day job with 1 hr lunch break and a 1 hr commute from home to work) that listens to music or watches movies on their way to work, uses their phone on their 30 minute or hour break, and watches movies/listens to music on their way home. Your battery stats are pretty good for 24 hours. The "average person" is out the house for about 12-14 hours a day and have time to plug unto the wall for atleast 15 minutes. If you can charge your phone for just 15-20 minutes while you eat on break (like most smartphone owners probably do already) with quick charge 2.0 (and soon to be 3.0) you'll have more than enough battery to last the day, and some, until you get home to charge for the night.
People who are complaining about the battery life must use android wear devices, wireless headsets, and keep your bluetooth on all day , and/or, are business men who are always traveling and don't have time to charge your phone, outside of those reasons I don't see why someone would need an incredibly large battery. I think that the fact that Android devices have been known for poor battery life for a very long time and people are expecting android 6.0 to be just as "battery hogging" which is why they think the 2150 battery is too small. Efficiency plays a huge factor that people are just ignorant to because they haven't used a marshmallow device or an iphone to understand it. Small batteries CAN last the day with the right operating system. Apple puts small batteries in their devices to maximize profit, but what if they put a 3200 mAh battery in an iphone 6s. the battery would probably last 2 full days with average usage. Point being the efficiency of android M seems to work wonders here. I'm wondering how much longer the Galaxy s6 battery will last after it receives the M update.
And to those who claim they don't have enough time to charge their phone or "find it annoying" to have to charge through out the day, you sound ridiculous. There are car chargers for people who drive, somewhat large (and affordable) portable chargers for people who commute via public transportation. Quick quick charging 2.0 & 3.0 . all you need to do is charge for 15 minutes, if needed, throughout the day and then you should be fine.
All in all, the average user should be fine with this phone. For you people that want a 4K display phone with a snapdragon 850 with a clock speed of 3.5GHz, along with 1 week battery life and 56 hours of screen on time for under $450, need to just pack it up. It's 2015 not 2051. Every phone will have its pros and cons. That's reality. If this phone isn't for you, then it isn't for you. Simple.

If this even is true, then you have a bad unit, I use mine like u describe and I got atleast 70% left when I come home from work.

At first I thought battery life sucked, but turned out to be a couple of bad apps (Sony life log and smartband). I ditched them and now getting similar life to my M8.
Last night I fully charged it then unplugged it to see how much charge it lost over night, so over 7.5 hours it lost just 2%. , which compared to the m8 (lost 9%) I'm pretty impressed.
Charge rate seems better too but could that be because it's such a small battery?

I checked the battery use last night. Facebook. ( Which surprisingly didn't come loaded) used 46% of my battery Yesterday ( Per Battery Use stats. ).
There is a good chance it is hogging. ???
As it stands now. I had the same morning and now I'm at 82%. It's been off the charger for 2.5 hours and I've only responded to a facebook message.
I have already turned off unnecessary settings to include enhanced 4G LTE calling .
Hopefully I'll see how it goes.
My screen is on minimum and it has already dropped from 82% to 80% in the time it took to write this.
This kind of feels like the Old days when the HTC EVO came out.

That is NO news about fb app. Never used it never will.

After a couple of days of usage, the phone is doing about ok for me. Screen on time is just as bad as phone idle time is good. Put them together and they are lasting my average work day.
Had plugged it out yesterday at 7 in the morning and when I returned at 5, it was 33% which is acceptable , given that it had been on Wifi and 4G through the day.
I just left it unplugged from the charger last night and the Doze feature really shines through. Screen shot attached.

Is it worth upgrading from m8 to a9?
Im thinking of getting the new a9 but dont know wrther to get an m9 instead. I am currently using an m8 but want to upgrade. Should i get an m9 or a9? Im sticking to htc phones as i like the desighn.

Light use endurance

Once in a while, when your significant other yells at you, you might use your phone a bit less. Rate this thread to express how the Google Pixel 2 XL's battery performs under light use. A higher rating indicates that the device goes a long time when you're using the phone sparingly: no gaming or video/audio streaming, light web browsing, some calling and texts, etc.
Then, drop a comment if you have anything to add!

Out and about (LTE/cell service only) - 13%/hour
At home on Wifi - 6-7%/hour

21h with 4h screen on, 40% left

With what I would consider light usage (email, web browsing, messaging, lots of YouTube) I have really been impressed with the battery life! Over 8hrs screen on time with my first few cycles so far. Based on this, I'm guessing that even with heavier usage (games, etc.) that I would still be pretty happy with the longevity. With very similar usage I was getting around 4-5hrs SOT on my original Pixel XL and was happy with it. Interested to hear how the battery has been for others as well.

I've been very happy. Last night I forgot to charge so I woke up with 48% battery. I plugged in for 25 minutes while getting ready for work. Left the house with 87%. Now, 9 hours later, I have had 2 hours screen on time of mixed wifi/LTE, browsing, email, Facebook, texting, a few pictures and a little YouTube. 20% brightness. Location set to high accuracy, Now Playing turned on, AOD off, Google account sync on. I am at 65%. That's a drain of 22%. Under the same conditions and usage my Nexus 5X would have drained over 40%.
This is the first smartphone I've had (I've had a Nexus One, Galaxy SII, Nexus 5, Nexus 5X and now Pixel 2 XL) that I can say that the battery life is GREAT.

This phone is ridiculous. I haven't charged it since Monday...
I won't pretend I'm a "heavy usage" person with my phone. But I've never been able to get 2 full days of usage from any of my previous phones. Most of them barely lasted 24 hours. This one is going to reach 48+ hours, easy.
I work from home full time so I'm connected to my home wifi almost all the time, which helps. I get out of the house a total of 2-3 hours a day to walk the dog, go to the gym, or meet clients for lunch. So during that time it's on full LTE with no wifi. I tend to use the phone for 2-3 client calls per day (30-60 minutes each while paired with my bluetooth headphones), listening to music at the gym (~60 minutes while paired with my bluetooth headphones), some light usage of social networking apps and Youtube videos throughout the day.
I know battery life consists of a large amount of factors but it's safe to say that with the same usage, this phone outlasts all my previous phones by at least 1.5x. It's fantastic.

Battery life sucks now compared to pre-February security patch.
Light endurance usage: 15% brightness w/auto brightness off just browsing, Facebook and a little texting on wifi. That's no games, Bluetooth off, Location on high accuracy but not doing much (ie no Maps navigation), no video, no music, no camera, no phone calls etc.
Pre February security update:
Screen on: ~10%/hr
Stand by: ~0.3333%/hr
Best battery life: 9 hours SOT over 1 day, 16 hours off the charger
Now (after February and March security updates):
Screen on: ~15%/hr
Stand by: ~0.5%/hr
Best battery life: 6 hours SOT over 1 day off the charger
Stand by battery drain up like 60% and SOT battery drain up like 50%. Very disappointing for a phone that is only 5 months old. If I break it down to a per mAh it's now no better than my Nexus 5X.

After first charge I am getting 2%/h standby drain, hope things will improve

SOT and idle drain still holding strong for my usage patterns. April update + root + Flash kernel. Not a social media user, and don't use many power/ram intensive apps :good:

just went 1 day 20 hours with 4 hours SOT and 20% left.
Data or wifi always on. Bluetooth and gps always on

No one listens to music offline only anymore ?
What is the battery consumption e.g. with PowerAMP (or similar players) and listening to music for several hours like in battery % ?
Thanks

Not me. I stream my music and play over Bluetooth. But for reference, the Nexus 6P was rated at 100 hours. So I doubt the Pixel 2 XL would be any worse.

Mine is just as bad now too. For the first 3 months the same time would leave me with almost 50% left.

I listen to music offline. For the first several months of having the phone I could play over Bluetooth and I'd use about 7% per hour. Playing over a wired connection used 4% per hour. Now it's like 8% per hour over a wired connection and 12% per hour over Bluetooth. Damn monthly updates.

Bad? LOL. What's bad for you is, I'm pretty sure, good battery life for him. I didn't get the vibe that he was complaining.

Compared to what it was for the 1st 3 months, yeah, that's bad. Maybe he never experienced how good battery life was before several of the updates so he doesn't really have a basis for comparison. Like I said, with the same time off the charger and screen on time I have about the same 20% battery left as well but for the first few months that same off the charger and screen on time left me with about 50% left. Draining almost 30% battery for the same use just a few months later is a big deal. Oh, and that's after trying a factory reset which at first (about a half a day) seemed like it helped but quickly showed that it didn't help at all.

What you were getting for the first three months was remarkable for sure but wasn't what everyone gets. Like a lot of things battery life has a bell curve and you were just on the extreme right of it. Now you're "only" getting what the majority, middle part of the bell is getting and unhappy with it. Still doesn't mean it's bad. Now it's just average.

Question Battery life since the last update

All was so good,
I was able to hold 2 days with my use (it was incredible, with my s10 I held 24h).
And, then, last update...
And now, in one night of sleep 25-30% of drain ??? Oo
What is that Samsung ? Are you aware like u destroy ur product with this... especially when you advertise about the terrific battery life of the s10 plus ?

I had my S10+ that ever had bad battery life, my s21+ looks like is much better, having 25% of drain in standby means there is an app that is causing that, when you talk about your last update, you should explain which version of firmware do you have now.

My T-Mo USA S21+ gets really great battery life. No change with the latest (AUAG) USA firmware. My S10 got very good battery life (24 Hrs +) but the S21+ (so far) gives me 2 days with MANY hours of screen on time.
Here's a partial dump of a discharge to 10%:

I'm using the exynos variant. I bought the phone on 13th Feb. The battery life is really realty bad for a 4800mah device. I was getting a expecting a decent battery life. But I'm getting like 4.5hrs SOT for 10.5 hours usage which is like half of what snapdragon verison is giving. This sucks. Should have waited for op9pro. Made a huge mistake.!!

Did you use it 60hz refresh rate ? This is insane battery life . I'm getting nowhere near this !!

I'm getting 2h SOT if I'm lucky, on AUB9.
Really wondering where those big differences between different users come from...

No, that is with Adaptive Motion Smoothness (120Hz) turned on.
I thought maybe my AOD was adding too much Screen On time, giving me a very misleading value, so in one of the tests I made i just played a few movies, and I still got hours and hours of battery life. I have no idea why there is such a variance.
Edit: So I thought of two things to mention. I run my screen brightness at about 35%. If you run yours much higher, that could effect your results significantly. If you use your phone outside a lot and it's set to automaticly adjust its brightness, that could set the screen brighness very high (for when you're outside). Also, I have bluetooth turned off.
2nd Edit: I ran another test last night and I'm surprised to report that there was no significant difference at full screen brightness versus my normal 35% brightness. I had Netflix playing for 3 hours at normal brightness followed by 3 hours at full brightness and the slope of the battery level curve is essentially the same. I'm at a lost to explain this as well as it's been my experience that screen brightness significantly affects power usage.
fwiw

My battery life seems okay but charging is very slow. I've never had so much trouble getting up to a full charge

I use it outside about 2 hrs a day. That too usage. Only for changing the song. Nothing more . I use dual sim .listen to music atleast 1 hour a day via Bluetooth. Even then what you are getting is truly amazing.

I did some tests the other night and much to my surprise turning up the screen from my usual 35% to full didn't make much of a difference.
I'm in the habit of using the "Close all" function in the recent apps screen almost all the time. Maybe that makes a difference?

I'm trying all the scenarios to reach that level of battery life but I go out for atleast 3 hrs a day. So I use my phone in mobile data as well. That also contribute. Yeah closing all applications all the time prevent unnecessary background process. That may actually help in apps like Twitter and Instagram.

Here is the latest I have managed . I removed one of the sim and used carefully . This is the best I have managed so far. But again, I use it outdoors with mobile internet for atleast an hour of screen time. 3 hours of outdoor usage . I'm still not sure if it's a good battery life but I will take it.

As a new S21+ owner I can say that I have had great battery life so far consistently getting 7.5-8 sot. This is with the latest march update.

Watch some YouTube videos on battery optimizations

My battery has been good so far exynos.

Hi. Looking at your screenshot, it seems you are using an Indian variant. I do not want to get into specifics, but Indian networks are far more congested compared to other countries. So the modem has to work 4 times as hard compared to say the US. Also, dual sims nearly halve the standby time. So the usage you have is fine and I wouldnt worry too much about it.

Have anyone tried disable auto optimize app daily and disable adaptive battery.
Some say it really improve the battery on the previous samsung gen. I'm going to try it. And report to all of you guys.
Just came up to xda to search about anything related to battery and didn't find the solution yet.
Sometime I got a good battery like about 6 hours sot. The other day it just to bad only around 4 hours. It seems auto optimize overreacting to apps and make it closed and open daily causing a worst battery live. And the adaptive battery just seems not good at all in some report.

My best so far today, 10h of SoT doing mostly multimedia stuff. Exynos, 4G, 60Hz, April update. No power saving mode.

Im currently trying out power saving mode at 120hz . I will let you know if this works.
