Hello everyone,
A while ago (right at the launch of the S2, total coincidence) I made the transition from a "regular" cell phone to a so-called smartphone.
I took a look at the S2 and liked what I saw, but read absolutely horrible things about the battery (i.e. not being able to get through a day with it). To me, that's not an option as that means I can't rely on it and thereby defeats the purpose of a mobile phone for me.
So I looked elsewhere and got me a Motorla Defy (installed Cyanogenmod 7.1 on it). I'm happy with this phone as the battery usage is okay to me; during the week it easily lasts a whole day to 36 hours with plenty of room to spare (not going to claim a consistent 48 hours, but it could get there every now and then). It gets these easy 36 hours with the following usage pattern:
- Internet connection is always on (it switches automaticly between wifi and mobile internet depening on availability)
- a few widgets (stock quotes) are always on and refresh about once every 5 minutes
- e-mails refresh about every 5 or 10 minutes, not sure, I'd have to check
- usually facebook app is on as well in the background so I get notices when somebody sends me a message
- regular texting during the day
- a few calls every now and then, usually only a few minutes a day
- reading the news online with the browser, not constantly but checking every now and then
- general browser usage while looking for adresses or random info etc
- little to no gaming
A few days ago somebody told me that the battery problems with the S2 had lessened due to new Android updates and such. As my brother needs a new phone I was thinking on giving him mine and getting an S2 myself, if battery quality is any good.
So basicly, my questions:
1) can I expect the same battery durability of the S2 as from my Defy now that the problems are supposed to be fixed
2) can I also put Cyanogenmod on it (as I'm used to this and like it) without any battery problems
Any information or feedback in this regard is much appreciated, thank you.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
No thoughts on this?
Battery use is very hard to gauge because the phone doesn't do exactly the same every day. In essence, estimates on battery life are like MPG ratings for cars: different styles and circumstances dictate usage.
Having said that, the less the screen is on, the greater the battery life, in general. If you are not happy with battery life, there is an official 2Ah battery which should yield around 20-30% extra usage.
I don't think SGS2 had any real big battery problems, or at least my set has never had big issues. Pretty much the same battery capacity since I first got mine and now with the newer firmware versions.
At the end of the end it all depends on how heavy you use your phone, how strong WIFI/3G/2G signals you obtain, running apps/widgets etc. Sure, the battery life is not great on SGS2 but it's also no worse than other mobiles with similar screen sizes.
I'm sure you can manage 24h with your usage, if not then you can always later buy the higher capacity battery which Samsung have released. It's slightly thicker but barely noticeable.
i got my s2 about a month ago with 2.3.3, battery was pretty poor at the start, wouldn't last a full day, but with some tweaking, i can now get roughly 2 and a half days use, albeit with light use. currently looking at my juice defender status in notifications, and says phone has been unplugged for 57 hours.
what i did/use.
2.3.5 stock firmware
juice defender ultimate
froze wifi sharing, ap mobile, social hub with Titanium Backup
screen brightness down to about 20%
turn off wifi when not needed
Basicly, what I'm wondering about is whether, given the use above, I could unplug my phone at 6am on friday to go to work, and only have to plug it in again at 8am on saturday with room to spare for any unforseen circumstances
Seems I finally found the question to which no answer can be found on the internet

I'm fairly disappointed in this battery and will start gathering benchmark metrics,asking others to do the same for more data points and what does and doesnt work to increase.
Currently I have disabled sense ui and reduced widgets down to hardly anything, just a search and taskiller. I seem to get around 10 hours with moderate usage (occasional short call, several texts and quick searches, etc) letting android download background data and check google accounts email, contacts and calendar (this really is the power of the phone, cloud syncing pim). Weather, stocks and other "widgetable" apps are refreshed only on demand.
It's worse than I thought. I went less than 6 hours today with only one quick call (<1 minute) a few youtube clips and 2 texts. I noticed the phone was pretty warm in my pocket compared to my HTC touch (it actually felt cold sometimes if left on the desk) and a few times I noticed that there would be no radio "bars" but most of the time I had 3-4 out of 5 bars (I never have recetpion problems where I am) leading me to believe that something goofy is going on with the radio. I am going to reset since my testing is over today!!

Whit what tool did you test it?
It's still to early to tell but I'm seeing decent battery life. Better than my pre but not great. Certainly acceptable considering I'm playing with it all the time since its new.
i also am seeing bad battery life.. i had court yesterday, and had it OFF most of the day.. and it was dead last night, i turned it on after court.
anyone notice this:
the website has extra batteries
http://nextelonline.nextel.com/NASA...oryID=BSH5110&topPageNumber=0&subPageNumber=0
they say 1340mAh. mine says 1500mAh
do you guys think thats a mistake?

I just looked at battery usage in Spare Parts at various parts of the day and input this manually to minitab. No special app or anything.

I read that the European version has a small battery, but because it is GSM is supposed to have as good or better battery life than the CDMA version.
The GSM Hero has a 1350mAh battery, and battery life is reportedly slightly better than the Sprint Hero even with its more capacious battery. As you correctly surmise, this is due to the Sprint being a CDMA network.
Why Sprint would want to sell a lower capacity battery though, I've no idea!

my battery didn't last a full day either
I am into my 3rd day of usage (on single charge) on my week old hero.
Running on 2G network, turning off all data connectivity, manual reduce screen brightness, minimum vibrate and sound notifications for typing and applications
I have a Sprint Hero and the battery is at half strength not too long after lunch. But since I've only had the phone 3 days, I probably am playing with it more than usual. I'm guessing Seido will come out with an extended life, same size battery. They did with my Touch and it was great! It was very handy having a spare battery when I was out for a long period of time, away from anywhere to charge the phone.
Im also into my 3rd day of usage, and been off the charger all day today... had a couple calls, couple texts, bout 3hrs worth of browsing/facebook/twitter... down to about 60% as we speak so i know its a vast improvement from my tp... hell, 2 hrs of anything on that phone and it would be below 50 percent before the day even really started lol...
There are a number of things you can do to help improve battery life.
1 ) Turn off Wifi autodiscovery. You can always turn it on again if you are at a spot where you know you have a good wifi connection and plan on using it. My Hero was constantly telling me about wifi hotspots that I was driving past. I've found a number of widgets that will turn wifi on with one push.
2 ) Set Twitter, Facebook, and or email to check for updates less often than stock. I don't remember exactly what mine was set to at the beginning, but one of the first things I did was set Twitter to every four hours and Facebook to every two hours.
3 ) GPS is also a battery eater. Turn it off unless you need it.
4 ) Whenever you get a new phone, you ( well, I do, I'm just assuming that you do, too. ) use the heck out of it, playing with settings, seeing what all the programs do, downloading apps and games. Battery life should pick up as the newness wears off.
If you guys want a little more juice, Seidio just came out with a 1750mAh battery that fits in your device's existing battery space and doesn't require a replacement door.

Problem is, whats the point of having a phone designed to have al lthese features if you can't use them as the battery just dies.
My T-Mobile G2 / Hero dies so quick it's annoying.
Yes I've been doing lots of stuff with it this week but to have to turn of 3G to save battery is a laugh. My old Sony phone uses 3G etc and it can last a good two days without charge.
I've kept my 3G on but have kept all the updates to minimum amounts or to be done manually.
Background data also turned off most of the time but again, if it's required, then we shouldn't have to turn off.
It's about time batteries were developed or the companies actually provide longer life ones.
All the testers reviewes keep going on about how great the battery life is doing all these things and stuff, what batteries have they been given to use compared to the rest of us I wonder?
First of all, hello to everyone. I have been reading through a lot of threads here in the last few weeks after getting my HD2, especially the ones about battery life.
I have never owned a smartphone, so I have no comparison but I'm barely getting through 1 day of use when fully charged! And I'm not even using it that much yet, Wifi is off, no data transfers, just some texting and calls. I have installed Bandswitch and Battlog, didn't really help though.
Got the phone brand new (T-Mobile US) and haven't done any major tweaking yet, it's still pretty much stock with a few programs that I installed so far.
Do you guys have a similar experience or is it completely different? I love the phone, but if I dont even get through one day of use (and I want to use the phone in the future, not just for surfing but for music streaming or web browsing), I would have to bring it back.
Any help appreciated!
It's just something you have to live with, buy a spare battery, or the extended battery, flash a lighter ROM, adjust screen brightness turn off push e-mails etc etc.
I can get 2 days battery from very light use. i.e. a few texts and calls a day, no Wi-Fi, bluetooth or internet browsing. That's just how smartphones are.
So how do you do it on a daily basis?
My battery is fully charged in the morning and lets assume I'm using the phone for what I bought it for - some music streaming, gps here and there if I need it, some web browsing, calls and texts etc.
I haven't even started using most of the features of the phone and my battery has died twice on my already while I was out at night.
How can that be normal or acceptable? I can't charge my battery every 6h...

Maybe you shouldn't have a smart phone? Battery technology is ****, it's a shame, but it's true. The only thing I can suggest is a spare battery, I carry one everywhere.
I generally watch an hour and a half of video a day on my phone, text, call, use the internet and I can still make a 9 hour day with 40%+ battery left, and just incase I am out and about in the evening before I have a chance to get the phone on charge I have the spare.
But with that said half hours charge from the mains will give you a good 30% topup I very seldom have to swap the batterys and I use a pretty juicy ROM.

or maybe not
Given his kind of use, 2 days should be normal. Right now I'm squeezing 3 days out of this battery, and that's only because I swap it out when it's at 10%, otherwise it could be a little longer... and a few calls here and there is not the only thing I did with it... it's still my work pda after all
Since it's pretty much stock, unless it gets better with time (the first recharging cycles are the worst) and even after a hard reset it won't get better, it probably is something wrong not software related.
Install battclock and check the standby battery drain, shouldn't be much higher than 4mA, up to 7mA could be normal, any higher than that, especially if significant, and you've got something wrong, and found the cause to the short battery life.
First off, buy a couple of cheap oem batteries from here...
Now, these eBay batteries have performed slightly better than the original battery...
Some of us smartphone users are so used to poor battery life we have power charging cradles at home work and car just to keep the charge up... And have spare batteries every in case of emergency...
I take my phone off the charger at 6am to go to work... My avg day is 6-10 calls, 20 reminders, an hour of UNO, an hour as a wifi router and I return home at 5pm with 50-60% battery life...
they are trying to make batteries smaller and thinner so they can make the phones thinner and smaller so battery life is compromised. But you do need to give it some time to settle in.
Back up batteries and cradles to charge them are cheap and an easy solution. So are extra chargers to keep at work, in the car, etc. Most people can charge their phone at least an hour during the day and that should give you all you need.
The only smartphone that I didn't carry an extra battery for was the moto q9c, because it came with an extended life battery. But on these phones, that probably isn't the best option.
So what did you guys do to improve the battery life of your HD2? Are there any specific programs (I heared about G-Profile) you are not supposed to use or did you guys just deinstall all the T-Mobile Apps?
If I can just get 1 day of actual use out of it I am OK with that. I just dont want to have die every second or third day if I use more often than normal...
Any suggestions or may tests I could do? I feel like I could stream music on Slacker for about 90 Minutes and the battery would be dead...
EDIT: Just did Battlog for about 15 Minutes, my phone uses between 15ma and 31ma when in standby. So where do I start, how do I find the culprit?
I love huge screen HTC devices and Im a power user, so my solutions for power issues are:
Callpod Fueltank Duo
http://palmtops.about.com/od/accessoriesperipherials/fr/Callpod-Fueltank-Duo-Review.htm
Mugen Extended-size High-capacity 2600mAh Battery for HTC HD2
http://www.mugenpowerbatteries.com/
There is a 15% discount right now, better hurry.
Extra chargers and thats it! Now I browse, calls, emails, music, videos, TV stream (Slingplayer) and maximize all of the other features of my HD2 t9193.
Software and the end-user are the cause behind battery drain. I've got 2.5days out of moderate use so I don't think it's the hardware at all.
Methods for testing battery consumption and proof it is typically software related
Hi,
At the risk of looking like I'm trying to hijack this thread, I started a discussion on this particular subject a while ago as feedback on my finding after reading almost all the threads I could find regarding battery use on the HD2. Lude219 is 100% correct, the issue is always software related (yea, I know there might be exceptions to the rule) and my phone was a prime example of that.
See the thread below that explains how to measure your battery consumption, has logs and screen shots from users you have high consumption and also people who have systems where battery life is more than 48 hours so that you can compare your results.
http://forum.xda-developers.com/showthread.php?t=718173

I'm also sure it's software related. My phone would use app. 2% overnight with all connections closed. This i tested over months. Then suddenly without me changing anything drastic software wise, it pulled 5% per 3-4 hours. So after going thru all the cleaning routines nothing helped exept a good "ram cleaning" . Somehow or other the phone starts processes over time wich consume alot of power. One would have to look into it with a process manager to find out what exactly it is. WinMo seems to be quite sofisticated looking at all the running processes. So my view is , keeping the system tidy might be the only way to save the extra power.This is where the huge diffrence to other platforms seems to be, it can take quite a while until you have configured your phone the way you need it. I am useing the stock rom 1.66 German
thanks you guys for participating and sharing your thoughts.
But now, here is a thinker:
Last night, I let my battery drain all the way to zero and then recharged it at night. The only other thing I did was installing BSBTweaks and Touch X Taskmanager. I also changed my Bandswitch Settings to turn off data when not used and put it at 60 sec (instead of 500 sec before).
And I couldnt believe what I was seeing, I took my phone off the charger this morning around 8.30am and now at 7pm I am still at 84%!!! I did not use the phone heavily but sent and received a few texts, made 1 call and played around with it for a little bit. Similiarly to what I did in the beginning after I got the phone, but then the battery had almost died at 7pm!
I am super happy and hope it stays like that but cannot explain why all the sudden it is that different...
Hi everyone,
This is a very usefull thread, for me it is, thanks to everybody that answered.
regrding the last post, a noobish quesition is
”Bandswitch Settings to turn off data when not used and put it at 60 sec (instead of 500 sec before): how do i do this?”
I remember stumbling upon this setting the day i got the phone and started viciously going through it.
Somehow it didnt store in my memory the path i went that day so i can try doing what the man sugested.
So if anyone can lay a hand, much obliged.
Regards
i lost 12 pct over night in 9 hours with my radio turned off last night and only gmail and texts were open...
with battlog how do i do the test so it stays in standby? it keeps turning the screen on and off when i run benchmark
You may want to flash a new radio. Try a new one each day and measure battery life. I use radio 2.12.50 and have had a good experience.
yeah but with my radio turned off the radio shouldnt affect it shoudl it?
i use blackberry to stream pandora radio thru aux for about 8 hours a day and it still has 2 bars left after that.
HD2 just sits there and kills the battery lol
what kind of phone is that when you have to disable all its functions every time you dont use it?
seriously this is called unfinished product or poor design, that is beeing sold to customers as a next best thing.
you guys can argue with me all you want. i heard many excuses from users advocating the companies. such as. if you dont like this than pay more for a better product. well HD2 is a better product, its a 500 dollar phone damn it.
but you dont realize that even the "better" products suffer from same underdevelopment syndrome.
companies spend millions on consumer research and consumers spend millions on **** they dont need every year. cows eat grass, consumers eat garbage made by big companies.
where are the better products? they dont exist because it became "normal" to have a faulty OS or for your phone buttons to fall off, or battery to explode.
companies worked long and hard to make consumers get used to the idea that garbage is just a part of life, and worked long and hard to minimize costs of production, and cut corners.
which corners?
the final QA testing that is not beeing done by a company, so they can release the phone 3 months earlier, the consumers pay for the phone and test it.
we work for the company and we pay for it instead of getting paid.
the phone breaks oh how sad ,
company takes note(dont use this cheap glue or the buttons fall off, get a lil more expensive glue next year)
so they use better glue and cut another corner and we buy another "new and improved phone" and this time screen goes dim oh dang not again...and it continues.
do you disconnect your car battery every night so it doesnt die? or when you buy a lexus do you drive with your AC off because it cant pull the car around when ac is on same time as the stereo?
After reading through so many threads about owners having issues with the battery life, I thought I'd start a happy thread!
I've had my SGS2 for almost two weeks now and I've always been happy with the battery life because it seemed to last a while.
I'm not up to the stage where i can just leave the phone alone (because I always want to play with it!), but I did an experiment 3 nights in a row to see how much power the phone drains in standby mode.
Each night, I'd charge my phone up to 100% and take it off the charger and then wake up to see how much power is remaining.
I left all the settings as-is and DID NOT turn anything off (eg 3G, etc).
The first night, I didnt touch my phone from 11pm and woke up at 7am to see that there was 97% battery left.
The second night, I left the phone alone at 11:30pm and woke up at 8am with 96%.
The third night, I slept at midnight and woke up at 8am to have 97% left.
If I average it out, it means that the phone on standby drains a lot less than 1% per hour. At that rate, the bettary seems like it can go with minimal use for at least two or three days. But it's something that I haven't been able to test just yet because I'm constantly surfing the net, testing out apps, etc during the day.
Admittedly, I don't have all that much installed on the phone that could possibly drain battery:
Friend Caster
Kakao
Whatsapp
Crazy Colours Live Wallpaper
Seekdroid
Official EBay
Battery Solo Widget
"Standard" clock
"Applications Running" widget
(I've got more applications, but the ones listed above are the ones that might have some sort of network connection and/or widgets that may need to update during the night).
I'm also using stock Vodafone Australia firmware in Melbourne city (in Australia):
Baseband: I900TDUKF4
Kernel Version: 2.6.35.7-I9100TDUKF4-CL331615
Build Number: GINGERBREAD.DUKF4
Does anyone else get battery life like this?
I'm not sure how big a role the network plays in these stats because I'm based in the centre of a major city.
As much as I hate the Vodafone bloatware, I've been reluctant to flash other firmwares like I did on my previous HTC Aria/HTCHD2/HTCDiamond because this one works so well with the battery.
3% battery over night ?. I get under 10%, with all off what can be off, with no funky widgets, no data, no wifi, no nothing. Still phone wakes up in the night for unkown reason and 80% of battery is taken by mysterious Android OS process.
I had Optus bloatware and I kept it for a week or two. I wasn't unhappy with the battery life but wanted to customise it and get root.
After flashing Lite'ning it was obvious how much less battery drain there was. I have since moved to Cognition and I am very happy with how it's going. I charge nightly, but I've never had the battery drop below 50%, and I do use the phone quite a lot. I wouldn't say I'm a heavy user (it's all so subjective) but I would have to be at least medium if not more.
I also love the Black Theme by Nitrozk and Pele, which is why I moved from Lite'ning to Cognition to begin with.

That is a problem with the 2.3.3 firmware mate. Best switch to 2.3.4 ASAP!
To answer your question, yes, I'm hugely impressed by the battery life.
Here's my latest and I'm still at 15%. I'm bone stock on KF3 with all the syncs set to every three hours and using Exchange push.
People blame everything (Wi-Fi Sharing, AOS) for their issues except what they do to their individual phone. Network signal strength plays a big role so does the individual router used for Wi-Fi access. But outside of that there's no other explanation other than individual configuration when identical phone's from the factory get such different results.
I don't participate in battery threads because they're pointless. Dozens of different people using the phone differently with different apps and settings on different carriers all talk in circles when there's no common basis for a legitimate discussion.
I'd call 3% overnight something impressive.
I'll try it out tonight.
I'm running 2.3.3 (No updates avaliable here in Brazil) and i'm not about to root it now. I'm getting a generic 7" tablet to mess around and learn how to do it properly.
So i'll be running minimalistic UI, Snowstorm, Battery Monitor Widget Pro on the desktop, with 2 screens.
HSPA+, bluetooth and wifi disabled.
Let's see how it turns out tomorow morning.
One thing i wanted was to flash in Samsung's oficial fw for Brazil, mine's a carrier customized one, and that's sort of pissing me off since i wanted to uninstall 75% of the garbage Claro has installed here.

I agree with you BarryH... having put the great battery stats in the first post, I wouldn't expect anywhere near that sort of level had I been playing with the phone or I had a thousand apps that run constantly in the background.
Having said that, it seems that there are the people who do have legitimate problems and then there are the people who simply have unrealistic expections of the battery in such a powerful phone. Kinda like buying a big truck expecting it to run on the same amount of fuel as a little car.

Let me know how you go Unreal... I saw on a thread a couple of weeks ago (not sure exactly which one now because there's so many of these "bad battery" threads) that someone had said that their phone lasted more than three days with minimal use.. and noone believed him! lol
How strange, I was about to make a similar thread. I had just gotten 3 and a half days out of my battery earlier tonight, no connection to charger since friday night. Minimal use of course, few phone calls and general tinkering, but still impressed with the standby. It was at 1% battery left so time to charge her up again. I charged my phone till the 100% alert came up, then charged it for another 45 minutes as I heard it stops it dropping immediately to 95% as some others have experienced. I've experienced similar too.
So after unplugging it, I pressed the power button to turn the screen off and haven't touched the phone till just now, about 6 and a half hours later. I pressed the power button and battery widget shows me 98% on the battery. If i was to leave the phone completely in standby and not use it, at about 1% drain per 3 and a quarter hours, that's about 13 and a half days standby!
I'm on 2.3.3 btw.
2-3% overnight drain is along the lines of what I get with KE2 and KF3. Data off, 2G. I get about 20-30% of drain a day, 30 mins usage, 30 mins talk.
I get great battery life on mine, although I have not made a valid experiment using quatitative data
Hopefully, this will be the NEW TREND for all the Android Gingerbread dual core phones.

We have one guy who went five days supposedly. The majority of posts in that thread are just like ours, a combination of moaning and pleased. It all comes down to how the phone is used and what's loaded on it.

Im very happy with battery life. Froze a couple of apps and I was good to go.
First phone I've had that didn't need to.be flashed on a daily basis.
I think anyone that's needs more than a day from a single charge needs a blackberry or a home to charge daily.

I have owned a lot of androids and my sgs2 has the best battery life.
I guess you think it's ok, probably because coming from another android phone, it is.
For me is a pain, every half day have to think about charging, my whole usage of this phone although brilliant, has been taken over by thoughts of how I'm going to next get it charged aposed to what I want to do with my phone.
Something I didn't expect was just how much this phone discharges whilst playing music with the screen off.

Im not impressed, it just met my expectation coming from an SGS1, but the first one impressed me so ergo Im also impressed on the SGS2
I have had this phone since pretty much near release date. I have been and still am very impressed,by the battery life.
I'm currently on KG1 2.3.4, but since before this past Saturday I was always on 2.3.3 (KE2). Even on 2.3.3 with the AOS bug I was still very happy with battery life.
Now with KG2 out, I'm sure ill be even way more impressed.
I love this phone, and I have been a religous iphone user previously too!

I must agree, this is my 3rd Android phone (out of a total of 37 phones since 1990) and it's by far the best battery of any smart phone.
My best battery usage is 3 days 13 hours with 25% battery left. That was with wifi on all the time, over an hour of screen time (I was working at home, so no need to play with the phone) and over an hour of phone calls. I'm sure it would have reached 5 days. BTW, I'm running 5 pages of widgets, firefiles wallpaper and GMail is updating all the time.
During the 3 days time I switched off 3G as this is the biggest battery drainer I have seen. I live in a 40 floor tower which is made of thick concrete and the 3G signal in my home office is terrible, the phone is constantly hunting for 3G. When I'm at home, I don't need 3G as I'm using Wifi.
I have been using my AT&T Galaxy S II for a while now, and I have run into a bit of an issue. I had been able to optimize my phone's battery to last almost 26 hours, but I don't even mind not getting that. I wouldn't mind even 20 hours at a charge. The problem is that I get intermittent times when my phone barely lasts 13 hours, even when doing nothing on it. Anyone got any thoughts??
Take a look in Settings>About Phone> Battery Usage. It should tell you what is sucking the juice.
You might want to look at what processes are running in the background too. You may have wifi/GPS/BluTooth enabled on those days... So many possibilities. Haha! Good luck!
*I also found this post over in the General Forum: [REF] Known identified battery drainers
This has almost everything to do with how you use your phone, and the conditions of your environment. If signals are weak, or you are checking email a lot, or getting a lot of texts, battery life can easily cut in half. Doing battery tests in a proverbial vacuum are the only way to really be certain, but they never represent actual use.
If you can get about 1 hour of screen time per 10-15% of your battery, you're fine.
If you can get about 1 hour per 1-2% of your battery during screen-off standby, you're fine.
Hello all, it's been a while since I've posted but this is quite a serious issue and could some guidance. A few weeks ago, I finally updated my Galaxy S9+ to Android 10 after being on 8.0 for so long and it's been a decent update so far. I had gripes with SoT not being the greatest but it was tolerable. Last night, I received an update for my phone and I installed it. Didn't think too much of it and continued on. I charged from my phone to ~87% today, used it lightly while working. By the end of my shift, I had 50% left.
I left the house to go for a 81 minute walk with 47%. I usually don't worry about having enough juice to make it back home but I experienced the worst battery drain I've had with this device so far. During my 90 min walk I:
listened to Spotify using my Galaxy Buds (one ended up dying towards the end because I forgot to charge them)
Checked Instagram occasionally and responded to some texts
Took 2 pics in Snapchat
Had a short video call on Messenger
It was right after the video call I noticed my battery was at 17%, which I thought was very strange. I don't leave apps running in the background for long and I have a habit of closing them out when not actively using them and I noticed the battery kept on draining despite there being no apps open besides Spotify.
Turned on the medium power saving and within a few minutes, I was at 5%. Decided to kill everything and pit my device on max power saving mode for the first time since I've owned the device. By the time I was home, my phone was at 1%.
I'm really baffled at how the battery drained at an exponential rate. I'm a medium user and I've had this phone since late 2018. Never leave location services on, never used AOD, and used the FHD display instead of QHD along with dark mode.
I'm hoping today was just an outlier as I want to keep this phone for another 2 years, but if this happens on a consistent basis I'm gonna have to start searching for a new device.
In the meantime, I have charged my phone to a 100% and disconnected the phone and observed the following:
Within 2 minutes of disconnecting, battery went from 100 - 98%. Not a good sign considering it was just idling
The battery continue to drain every other minute and I could see the battery go down on each unlock
Wiped the cache partition and I went from 93 to 94% for a brief moment prior to the phone going back to the same pattern
This is very worrisome to me as I don't believe the phone will last until midnight, I'm wondering if it's possible to roll back to the previous update.
TL;DR - After the update yesterday, the battery drained at an exponential rate despite light to medium usage
Also, here's some screenshots of my battery usage

I know this isn't the answer you are looking for, but all I can do is suggest changing the battery and doing a full, stock firmware flash via Odin to completely wipe your phone.
I recently replaced my phone's battery and did flash the firmware and my battery is really hanging in there. My battery was also 2 years old and before, I would get about 3h SOT when I play a game (and I do a lot). Now, I'm getting 5h SOT no problem with about 2-3h gaming included, so I really do suggest a battery change. I'm thinking you could be able to squeeze another 1 or 2 years into this amazing phone.
