Hello there, I was hoping someone would help me on here with a problem I'm having with my S2
The batery barely lasts me 6 hours on fair-low usage and I have the screen always at 0-50% brightness, power saving mode enabled.. But always the same story with this phone. I bought it used, at first I thought the battery was dead so I bought a new one, still the same story is told by the battery life... I also noticed at first that the screen doesn't look that good in terms of colors and it looks dim, In the sun, even at 100% I can barely make what's on the screen, and in the battery manager, it's always the screen showing +45% usage of the battery... Which is barely used since I am mostly on and off on the phone. I'll provide some screenshots. Do you think replacing the screen would make the problem go away? Or is this just a S2 thing?

On the last screenshot the phone was left overnight and you see as I turn on the screen the battery just drops insanely fast with less than 2 Hours of on time...
Just an S2 thing, certainly with the battery usage at least. Screen on will always be your biggest battery drain. Plus you obviously played a lot of a very CPU/GPU intensive game; what do you expect - it's a phone, not a console. I mean, you lost 13% battery in just under 2 hrs with screen on half the time, that equates to around 4-4.5 hrs & that would be rather good given the game you were playing.
Nothing you've said strikes me as really sounding like the screen dying based on that (the battery usage), though on the other hand 'doesn't look that good in terms of colors and it looks dim' suggests there might be something going on with the screen.
You don't sound like you're experienced diagnosing electronics like this, and without the phone in front of them, nobody here is going to be able to give you an absolute answer, so your best bet is to take it to a phone repair shop you trust to give you an honest opinion - that is, they'll take a look at it & tell you the truth does the screen need replacing/not. I don't know about where you live, but some of these guys where I live I wouldn't trust to give me an honest answer (but obviously I wouldn't go to them in the first place), they'd replace the screen & pocket your money regardless.

On the screenshot that the game is being shown as a battery consumer, the phone was only on for 1h44 minutes and all I played was about 20 minutes on the bus, why would you take conclusions like that? The screen is still taking more energy than the game, tho making it so the game isn't the one to blame about this when I used my phone on the bus, having the lowest possible setting on the screen brightness. I'll do a test tomorrow, have the battery fully charged, wifi only and phone on airplane mode and only text from time to time and then at the end of the day or the battery, show a screenshot of how it went.
Actually, according to that screenshot, you played the game for more like almost 35 minutes, and you had the screen on for almost 53 minutes. And as I was saying, if you extrapolate those figures & the amount of battery you lost for that period of time, that is absolutely normal. If you kept that usage pattern & got ~5 hrs screen on with 3 hrs of game time, you'd be stoked with usage like that. If you used less or no game, you'd get even more screen on than that provided whatever you did with the screen on wasn't too CPU/GPU heavy.
No amount of your simplistic testing is going to tell you whether you have a problem with the screen or not. All your proposed test tomorrow will do is give you an indication of how much battery you go through with minimal usage & nothing else. It's a pointless exercise for the problem you say you're concerned about.
The only way you're going to know that one way or another if the screen is on the way out is to have someone who can diagnose hardware take a look at it & test it. Your 'tests' aren't going to do that.

??? I did read the whole thread. I don't post unless I have. You're welcome here, I just don't understand what else you're waiting to be answered? Use the phone normally (as the screenshots look fine to me & MistahBungle has explained how they are fine), else, if your screen is dim and isn't showing colours properly, then it's likely a hardware fault of the screen/connections... hence get it looked at by a service centre/mobile shop.
Edit : have a look at my screenshot. Screen usage for me is over 60% over the same course of time as your second screenshot.

I've loved my Galaxy SII right from day 1, but the phone's battery life has made it a complicated relationship.... I'm hoping to share my experience as a heavy user and how i'm dealing with the battery.
My usage:
I would fall into the 'power user' category. I'm rooted, on stock 2.3.4 (the update to 2.3.6 was pushed to my phone, but obviously failed). I'm often streaming audio podcasts, using Waze (a social gps program), and checking twitter and online forums and the occasional email or text. Bit of youtube in there as well. Bluetooth is on 10% of the time, wifi always, screen 1 notch below max brightness, no 'fetching' widgets.
My last phone, the iphone 4 had better battery life, but not incredibly so. During heavy use I would get ~6 hours. Standby was closer to 20 hours. I still had to charge at some point during the day, but it's different with the GS2.
Let's take a look at the Battery Usage in Settings....

With 4 and a half hours of usage, i'm down to 13%. That means I'm up at 8:00AM, and by 1:00PM my phone is dead. It would almost be hilarious if it wasn't so sad... Charging has become a critical part of my daily routine. I'm using an external battery pack (more info below) and charge off a wall socket
Solution so far:
I've been using the Energizer XPAL4001, a 4000mah external battery for $58.00.
The thing is great, and I obviously wouldn't make it a full day without it. However it's a hassle to have to lug it around which is why i'm considering getting the extended battery which I was hoping to avoid by getting the external. But it looks like I do need both solutions.
Solutions I'm considering:
I'm about to pull the trigger on a3500mAh Extended Battery + Cover off of ebay. It's going for $11.00 with free shipping, so the price is certainly right.
What do you guys recommend? Has anyone tried the battery I'm looking at? It doesn't have NFC, but it's $11. I'd love to hear from other power users and how they're dealing with things.
PS. Still love my GS2
I'd recommend using your phone less!!
Try an i9100 rom, much better battery life.
You are expecting too much if you want it to last all day long with that much usage.
Doesn't look like your phone went into deep sleep not once.
Try flashing UnNamed 1.3.2 or 2.2.1 and a custom kernal and use SetCPU to lower clocks/volts.
This should help you in increasing the battery life a little more.
Have you checked this thread? http://forum.xda-developers.com/showthread.php?t=1308030
What about the Korean 2000mah battery? You can see my posts on this page for more info: http://forum.xda-developers.com/showthread.php?t=1281777&page=11
It would be helpful to know how much screen time you are getting. You can access this by clicking "Display" in the screens you have posted above. Your battery is dying incredibly quickly. If your screen time is less than 2.5 hours you may have a rogue app that is running up your cpu. Use CPU Spy and better battery stats to help diagnose.
Sounds like you are such a power user that you might want to consider one of the 3500mah batteries. If you don't mind the size that is. Search the accessories forum to make sure you order the right brand as some cause boot loops. You will also lose NFC.
Good luck!
thanks for the replies everyone.

Sorry, but no. I would carry a second phone before using this one less. But it's a reasonable recommendation.

I'm not expecting a full day of battery life, but 4 and a half hours of usage in undeniably on the short side. Thank you for the insight on deep sleep etc. I'm newish to android and appreciate a skilled user's input.
As for flashing a rom, I'm really waiting for an Ice cream sandwich release before going that route. I'm aware of underclocking etc but think that I might get better results by getting the extended battery.

I think i'll need 3500mah too. I'm aware of the boot loop stuff, but I can't find clarification on whether the battery i'm looking at ( ebay link ) will have those problems or not... I would like advice on that.

Time on: 2h 57m 20s
I will look into those 2 apps.
This is what I have for today with better battery stats.
/\ were you using the GPS? I was for most of my 4 hours of life.
what were you doing with your 2 hour 26 min of screen on time?
Hmmmm, 3 hours of screen on time sounds about right for the battery life you are experiencing. As far as that particular battery, I'm not sure... I would play it safe and purchase one people are linking to in some of the threads that are confirmed as working. The other thing you have to consider is cover fit- which is another reason to go with one people have posted experience with in one of the "Accessories" threads.
BTW: Not sure but the Waze app may be utlize GPS in a way that it consumes more battery than it posts in your battery usage. Not sure though.
Also, are you leaving the screen on unnecessarily, like while listening to a podcast. That's a pretty intense amount of screen usage for such a short period.
Let me know what you decide
Just for Reference
Here's my usage with the 2000mah Korean Battery.
Screen is off during podcasts, on during GPS. Waze affects my battery about as much as the google Maps/Navigation app.
As for the battery, I've heard others buying batteries that have been $50 and up, I could buy 4 of the ones i'm looking at for that price.
Someone out there must have tried this battery before.... I'd like to hear what they say first.

Install BBS (link) and cpuspy (link) today and then tomorrow make sure to reboot your phone before unplugging and doing your daily routine.
Once your battery reaches 20% post the BBS dump and screenshots so we can analyze it better and see what is draining your battery so much and how to improve it while you wait for your new battery.
I highly recommend flashing a UnNamed or ShoStock since it removes bloat and also SetCPU to lower the volts and set some profiles.
You said your new to android, so listen to others that have used it longer.
PS. Ice Cream Sandwich will be a while so don't hold your breath...

I use gps for about a minute today. Most of my screen on time is messaging web surfing facebook and twitter
Was your screen at max brightness or autobrightness? Autobrightness tends to set the screen way too bright.
After all, your battery history indicates 74% of the usage was display - so I think you may just have the brightness way up.
Full brightness + GPS + CPU usage is brutal on the battery, that brings total current consumption to somewhere around 650 mA. (On the Infuse, the battery would slowly discharge with a 600 mA charger at fullbright + GPS. The GSII just barely keeps ahead with 650 mA charge current.)
I'm getting between 26-32 hrs with the config in my sig.

Alot of good advice in this thread! I highlighted above what I think is killing your battery. Go with a debloated stock like ROM, research a bit on cpu schedulers and go with a conservative one, turn the brightness down and you will be on your way to duplicating your battery life. ;
Use Siyah kernel and the Thunderbolt (TB) script. They'll do wonders for your battery. As for brightness use auto or half way. We're lucky to have such boss screen with crazy brightness. anything above 70% hurts my eyes in doors lol. Auto should be 90% effective for your day to day use. Also try to avoid apps that sync or fetch data constantly and set things to push or to auto-update every 3-6hrs instead of 15min-1hr. Those murder ur battery.

I was one notch down from max brightness. I'm going to scale it back to around 50% as many people are recommending that.

You know that isn't good for Li-Ion batteries...
http://en.wikipedia.org/wiki/Lithium-ion_battery#Prolonging_battery_pack_life
Charging via plug yellow triangle seems to be coming and going.
Is it your first time get a thing like that? If its your first, then I think something wrong with your battery.
Low battery shows red indicator, it shouldnt be green just like the picture.

Hmm. You said you "always charge your battery from dead flat" before. That made it sound like you were doing it on purpose. But I digress.
Also, you should have no problems having the battery go the full day, (I can go the full day no problem - unless I'm constantly using the phone) unless you have something holding a wake lock. Have you installed BetterBatteryStats and monitored your wake locks to see if something is misbehaving?
Yes I have wakelock issues, But last time I tried to give starts thier was an issue with how I submitted it from the phone.
Anyway I sleep very little, and my phone is almost ALWAYS on the lack of a "proper job" means I don't have an 8 hour period of time where my phone isn't getting much use.
Do NOT worry its normal the triangle appeared because your battery has totally finished just Wait for 2 minutes and the triangle will disappear

Well, you should focus on solving those, and your battery life will improve.
Otherwise, my only other advice is to simply have more chargers readily available. I keep one at my office, a car charger each in my car and my girlfriend's car, and a couple at home.

That does look pretty bad. What is your details under display? (screen on time)
EDIT to add: actually, your screen looks like it might be on for a long time? (solid blue line under battery graph, starting under the "m" in 4h 56m 15s on battery text) If your screen on time is around 3.75 - 4 hours, this is normal.
To get a better gauge, post screenshots after you click both the battery graph above, (which will show signal, wifi, screen on, awake, and charging graphs as well) and the Screen entry. (to show screen on time)
Yea that screen shot is a week old, I will keep and eye on it.

chamonix's reply suggests you try a different modem, essentially. He's saying that in the dump you posted, RILJ held a 3.5 hour wake lock, which is unusually long. Could be that the modem you have flashed right now was struggling to find signal, so it was holding a wake lock.
Have you tried flashing a different modem yet?
Yea i've changed kernel/modems since then, Should I be selecting Other Partial Wakelocks Kernel wakelocks Alarms or Process?

Depends on what you want to look at.
But you're saying the screenshot above is a week old, and the BBS dump you linked to is clearly months old (from Feb 17), so maybe it's worth it to post more recent screen shots and dumps? Otherwise, can you honestly say you've not changed ANYTHING on your phone since either the screenshot or dumps were taken?
No one can tell you anything about how your phone is behaving today using information that is outdated.
The screenshot nothing has changed since then, I have changed things since the dump.
Well I want to kind out why my phone is awake when my it should be sleeping I supppose.
That screenshot their was a day when I woke up and used the device for an hour or so, and then I hadn't used the phone till about 12 hours later.
As you can see the phone kept waking up most of the day.
The info on Android OS for that screen shot was CPU Total 1h 6m, Kept Awake 4H 9m
I was able to get 5.5 hours of on screen time with the phone being on for 17 hours.
That is with a mix of youtube, phone calls, small amount of Netflix for testing, watching a movie from SD Card.
I left the Wifi on the whole time as you can see with one of the screen shots. I did have on Stamina mode.
This was after letting my phone charge the first time to full and not plugging in again. The down time with the phone not being used was because I left it on while I slept. In 8 hours the phone only dropped 8% while I slept (very good).
So to answer a lot of questions about the battery, it is AWESOME!

Could you give us a bit better test , like more usage , I mean screen time is great but you barely did anything in t he phone , 41% of app usage is nothing , 1 min of phone call is also nothing.
Don't get me wrong I'm interested into xzu but I'd like to see regular / intensive usage , also could you tell us which brightness you were using ?

This was Web surfing, watching Netflix, you tubing, etc. It never just sat with screen on. I actually used it the whole time.
Screen brightness was about 30% the whole time.
With the screen at 30% brightness, was the perceived brightness level pretty good? Maybe a little low? I'm curious to know, because I suspect lower brightness settings than usual will be satisfactory with this display.
Screen brightness is good. Although I have not tested it outside in the sunlight. I am going on a canoe trip tomorrow so I will be able to test the waterproof and brightness out
**** dude, be careful, lol. I'm sure the phone will be fine in the water, but I'd hate for it to slip out of your pocket and be gone down the river! You'd never find it. Makes me sick just to think of, lol.
Anyway, I am definitely getting the LTE version of this when it becomes available. Thanks for the battery and display insights.
That's why I bought the insurance haha.

I was able to get 5.5 hours of on screen time with the phone being on for 17 hours.
That is with a mix of youtube, phone calls, small amount of Netflix for testing, watching a movie from SD Card.
I left the Wifi on the whole time as you can see with one of the screen shots. I did have on Stamina mode.
This was after letting my phone charge the first time to full and not plugging in again. The down time with the phone not being used was because I left it on while I slept. In 8 hours the phone only dropped 8% while I slept (very good).
So to answer a lot of questions about the battery, it is AWESOME!

In the first attached print screen with the list (phone, screen, phone radio, etc.) how did you disable the graph at the bottom to show up or how to make it disappear?, thanks
I had 18hrs 40mins of up time and 5hr 15mins of screen time. 3G/WiFi mode, Stamina mode OFF
Usage includes web surfing, facebook, messaging and video playback (1hr).
Don't worry about the brightness. ZU at 0% is brighter than S4 at -1 (lowest is -5) lol. ZU really had a bright screen.
Mine after second cycle. Not so good isn't it?

The battery capacity won't be at max after just one or two cycles. Use it for a full week and then see how it performs.
So far for me, I am down to 24% after 10 hours. I won't make it through the day since I"m still up for 5 more hours. This was on moderate usage. With Stamina Mode Enabled.
- one phone call
- three emails
- checked facebook twice, and instagram twice
- watched 20 minutes of youtube tho
- listened to music while working out for one hour
- 57 texts sent/received

I don't know, over 3.5 hours screen on time with 17% remaining seems pretty good to me. I haven't really done any formal tests, but I don't seem to get much more than about 3 hours screen on time with my Nexus 4 period, let alone with almost 20% remaining, and I can always make it through a day. This is would be an upgrade for me. The most telling thing, however, is the screen brightness. About where did you have it set?

I set it to minimum with auto brightness. So no specific number. That's acceptable to me but not so good. And we have to wait until 9 September to get the true Rom.right now only what we use is Xperia Z Rom. Not for ultra. Let's see how it goes then. Looking for better camera, screen and batt

Battery life seems to be totally acceptable, I never saw a powerful smartphone able to survive an heavy use for a full day or maybe at its time only the Nokia 6310i able to last 4/5 days of heavy use, but it was a tiny monochrome screen for a big phone and huge battery. And yet there i still no ROM/Kernel available so the battery life can be optimized.
But a question, what about the charging time?

And what is the DC current output of the Sony standard charger?
I just got my Note 7 yesterday and so far I'm pretty happy with the battery life. It's a great improvement compared to my previous phone (iPhone 6+), though I'm still figuring out on things to do to make the battery last longer.
if you want the maximum battery life, then disable animations in the dev settings (look around to learn how to get there if you don't know. only saying it cause you said you came from iPhone and thus idk what knowledge you have on android lol).
Um, also use minimalist wallpapers with a dominate black aspect.. (as in, use a wallpaper that is mostly pure black, since with AMOLED screens, true black means the 'pixels' are turned off completely, thus saving you a tiny tiny bit in battery). Also just don't use live wallpapers in general.
Ummmmmmmmmm..... oh, don't keep the phone at 100% alot. I'm kind of a hypocrite with that one though. I keep mine around 100% all the time because I never know when I'll randomly be out of the house for the majority of the day. thus having a 'full' battery means possibly an extra 30 minutes to an hour of 'usage'. But this also means that the battery will not last as long later on during its life. It also produces its most stable power delivery around the 83-85% area, so that's where you get the best 'bang for your percentage' so to speak. You'll notice it stays in the 83-85% range alot longer than it does at any other percentage.
But all in all, just keep the brightness down to a reasonable level, don't install apps that constantly run in then background (for example, I recently started using a podcast app called Pocket Cast, and ever since installing it, my battery % at the end of the day is generally 60% less than usual. As in, i normally can end my work day with about 78% battery remaining during an 8 hour shift, but after using this app, i'll be lucky to make it out with 10-20% battery. It seems to hog the battery when you're using it as well as when you're not. So at this point, I'd highly NOT recommend using it, even though its such a pleasure to use. Wow this was a long side note haha.), don't use the phone if its hot or cold, and idk I mean, everything I've listed is pretty much everyday basic things. So I doubt you are someone who doesn't already know these things XD

Thank you for the very informative reply, i have been switching back and forth from iOS to Android (eversince the first iPhone the first Xperia X10)
It is indeed an awesome switch for me this year, i hated my iPhone 6+ and the more i use the note 7 the more i like it. Given that it isn't "perfect", it's keeping me satisfied so far.
Let them tips coming

Well the biggest tip I can give is this: GET A GLASS SCREEN PROTECTOR.... if you don't, you will regret it within weeks. The "Gorilla Glass 5" screen is complete crap. It scratches easier than plastic screens.... most Gorilla Glass phones have a hardness of around 5, but the Note 7 is only a 2-3. Some people have their phones scratching at level 2, others level 3... level 3 is just slightly better than plastic, and level 2 is worse than plastic... So get proper screen protector for the front, probably one that is good to be used with a case if you plan on getting a case as well. I'll personally be getting a DBrand skin for the phone and a screen protector from a company called Myrax? I think that's what it is. lemme go check.
Myriann is who makes it =3 https://www.amazon.com/dp/B01JFHA16G/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=KYMJDORDQX1V&coliid=I2ELMRA3UAHQMC&psc=1 and here's the link to its page. lol.
I thought the TGSP for the "edge" type phone is a hit and miss. I mostly read bad reviews about them and i think i only saw around 5 good reviews (or posts here) out of like 50 reviews
Have had mine for around 24 hours now and after a good charge after buying it, I got around 6.5hrs of SoT. Pretty happy with that. Only gonna get better haha.

The battery saving option really does work!
Move from 6s Plus to Note7, I'm not really happy with Note7 battery life. But I think it will improve in next two week. I aslo need UVable kernel to make phone cooler as I did on Note5

Will updating affect the "rootability" of the phone?
First run (52-0) I got 4hrs SOT during initial set up.
2nd most present run I got 6hrs 26mins (8% left) within 15hrs of usage, although I played Pokemon Go for 3hrs on max brightness which did some pretty hefty damage.
For those who want max battery life, this is what I've learned in my limited time:
- Download (buy) Package Disabler Pro (PDP) and disable the bloatware
- Disable the unnecessary sensor stuff throughout the settings app
- If you dont use Always On Display, disable it
- Disable Auto Brightness, and use the minimum brightness manually
- If you play Pokemon Go, download "Battery Saver for Go", it turns the display off when idle
- Enable MID Battery Saver mode with unchanged resolution, enabled Limit Performance, and disabled Prevent background network (if you stream or need it, otherwise enable it). Set max brightness to 80%
---- Be sure to re-enable Device Maintenence in PDP to get customisable power savings back.
- If you want, use the BLACKEST theme you can. I personally dont like any of them, so i kept to Samsungs stock theme
- DONT USE FB OR FB MESSENGER, TWITTER, INSTAGRAM etc. Use the web versions
- DONT USE CHROME. Samsungs Stock browser takes time to get used to, but its much more battery friendly
Without me playing Pokemon Go, I could have easily pushed for 7hrs SOT++ which is damn impressive for having the brightness at 80%.

I've got the Exynos model of the s9+ and it appears to get pretty hot. Almost uncomfortable at times.. this a long with battery drain when I've got barely any apps installed is pretty poor. Note 8 never had these issues.. anyone else experiencing this?
Pretty common for a samsung phone why are you surprised

This is NOT normal. Install aida64 or any monitorung software and check your temps. You may have a faulty unit! My temps right now on exynox are 34.5 cpu and 34.6 battery with normal usage
Is this normal?

Samsung's cooling and clock speed are just fine for normal use. Runnning Antutu is NOT normal phone use. Why slow down the phone for everyone else just to run some silly benchmark.

I'd like my phone to be stable at all times, in any situation, especially at this price point.
I also was shocked to see it since I never had it with any other device in the past.

My US unlocked s9+ never got uncomfortable hot/warm even under heavy task like gaming. And, during normal use like- calling, texting, chating, browsing it never got any hot/warm. Just normal. During 16 to 24 hrs of usage- i got avg 5:30 to 7:30hrs of screen on time
This thread has been cleaned now lets get it on topic...
Same happened to me
Found out that the problem is with battery temprature..did a settings reset and now back to normal..seems to me it's like a bug with some settings
Update
Again battery temps hitting 37degrees during normal work such as whatsapp and youtupe...feels a little warm..asked samsung and told me to get a replacement..
Hi, same here. I have Exynos 9 plus model and all of a sudden, apparently without any reason, it starts to burn...yesterday it was at 42...I'm a Samsung lover I had S5, S7 edge, S8, Gears s3 but now i'm quite upset because I spent a lot of money for it and now I have to do a reset factory to see if I can solve the problem...I spoke with Samsung care and they told me it can depend on the many apps I've installed in it...maybe, he said, it depends on Nova Launcher! I can't belive that I've always had Nova Launcher and now in a 1000 Euro phone I cannot use it because of the heat! The heat it always starts on the camera zone on the back
Had this with the Snapdragons before but the Exynos usually cooler, have you checked to see if it has an app running in the background causing it

Yes, I've installed System panel and Gsam battery monitor but i can't see any app the in particular is going crazy. I can see that sometimes, without any specific use, is starts to burn untill 42 like yesterday; I restarted the phone but i keeped doing it. I've took off all the background working for many apps like spotify and others....Now i'm doing hard reset and I will see...

Maybe better, maybe...you know the heat was going along with a strong battery drain. So I will wait one day to decide if bring it to assistance or not...
By the way, it's not fair to spend time to try to fix problems in a 1000 euros and 3 weeks phone and eventually bring it to assistance and stay without it for one week...I need the telephone for work!

?? mine appears to be normal now...dunno what changed
For me the video enhancement feature in settings was causing increased temperature and also battery loss. Turn it off and it will surely increase the battery life.
Mine gets warm too, but randomly. It stays cool most of the time. But all of a sudden it would get warm in my pocket. Don't know what's going on.
S9 overheating
Hi. I have been having the same issue. I took my phone back and got a replacement due to it overheating but the new phone overheats as well. It overheats the most when I use the Screen Mirroring (Smart View) feature to watch movies on my Samsung smart TV. I am curious to find out if this happens to other S9 owners as well. While I am watching movies using this feature it gets so hot the phone will freeze up halfway through the movie . My kids were watching a movie and they said the screen displayed a message stating it overheated and then shut off. This doesn't happen with any other of my other Samsung phones. I was walking with the phone on my hip on day and it started to get hot as well. I am so disappointed. I really am a fan of these phones but this is a huge problem of course. Also my first phone was was trouble shooted, updated and reset but it still had the same issues unfortunately. I had to go through all those steps before getting a new replacement device.
